Description

granulator

This invention relates to a pelletizer, and more particularly to a pelletizer that can process and recycle waste materials at low cost.

Currently, the construction and manufacturing industries use materials such as wire, wood, and polystyrene to make items. After these materials are cut, waste residue is left behind. This waste residue is usually sent to a recycling center, where it undergoes chemical processes to remove impurities and purify into clean raw materials, thus enabling the waste to be recycled and reused.

However, conventional chemical processes for waste treatment are costly. Therefore, developing a low-cost waste treatment system has become a worthwhile research topic.

The primary objective of this invention is to provide a pelletizer for the low-cost processing and recycling of waste materials.

To achieve the above objectives, the present invention provides a granulator comprising a feeding module, a pressurizing zone, a pressurizing assembly, a conveying module, and a power module. The feeding module receives a raw material and includes a main auger. The pressurizing assembly is located on one side of the feeding module and connected to it via the pressurizing zone. It includes a tube, a piston, a pressurizing assembly outlet, and a pressurizing assembly drive. The tube surrounds the pressurizing zone. The piston is located below the pressurizing zone. The pressurizing assembly outlet is located at the top end of the tube. The pressurizing assembly drive is connected to the piston to drive the piston up and down. The conveying module connects to the pressurizing module. The conveying module includes a top opening plate located at the pressurizing module's outlet, used to open or close the outlet, thus maintaining either a closed or open state. The power module drives the main auger, piston, and top opening plate. When raw material is fed into the infeed module, the rotating main auger moves the material towards the pressurizing zone. When the top opening plate covers the pressurizing module's outlet, the material in the pressurizing zone is pushed and pressurized by the piston against the top opening plate, thus compressing the material into compressed material.

According to one embodiment of the present invention, the feeding module is inclined relative to a horizontal plane, such that the feeding module has a first angle θ relative to the horizontal plane.

According to one embodiment of the present invention, the granulator further includes a control module, and the feeding module further includes a plurality of detectors electrically connected to the control module; the plurality of detectors are used to detect the amount of raw material in the feeding module.

According to one embodiment of the invention, if the plurality of detectors detect that the amount of raw material in the feeding module has reached a specific threshold, the plurality of detectors transmit a full-load message to the control module. The control module then transmits the full-load message to the power module, which in turn causes the feeding module drive to rotate two flaps according to the full-load message.

According to one embodiment of the invention, the control module further includes a pressure detector for detecting pressure within the pressurized zone.

According to one embodiment of the invention, when the piston pushes the material inside the tube toward the top opening plate, a pressure detector detects whether the pressure in the pressurized zone reaches a pushing pressure.

According to one embodiment of the invention, the feeding module further includes a main auger and two flaps, the two flaps being located above the main auger and the secondary auger, respectively.

According to one embodiment of the invention, the feeding module further includes a feeding module driver, through which the power module drives the main auger, the auxiliary auger, and two flaps.

According to one embodiment of the present invention, the feeding module further includes at least one sprayer for spraying adhesive onto the raw material within the feeding module.

According to one embodiment of the present invention, the feeding module further includes a heating element for heating the raw material within the feeding module.

According to one embodiment of the invention, the conveying module further includes a conveying module driver, through which the power module drives the top opening plate to move relative to the outlet of the pressurized module.

According to one embodiment of the invention, the conveying module further includes a conveying channel located beside the top opening plate to facilitate the separation of the compressed material from the pelletizer.

According to one embodiment of the invention, after the raw material is compressed into a compressed material, a top opening plate moves to open the outlet of the pressurizing module, and a piston rises until the compressed material moves through the outlet of the pressurizing module. When the compressed material has moved through the outlet of the pressurizing module, the top opening plate moves to close the outlet of the pressurizing module, and moves the compressed material to a position on the conveyor channel.

According to one embodiment of the invention, the conveying module further includes a screen plate with a plurality of holes, the screen plate covering the outlet of the pressurizing module, the plurality of holes for raw materials to pass through.

According to one embodiment of the invention, the conveying module further includes a moving plate and a moving plate driver. The moving plate is positioned above a plurality of holes, and the moving plate driver is connected to the moving plate and used to rotate the moving plate. When the raw material passes through the plurality of holes, the rotating moving plate breaks the material to form granular compressed material.

According to one embodiment of the invention, the conveying module further includes a pusher, a conveying channel, and a conveying module driver. The pusher is located beside the screen and connected to the conveying module driver, and is used for lateral movement to move the granular plurality of compressed materials onto the conveying channel.

As shown in Figures 1 and 7, in the first embodiment of the present invention, the pelletizer 1 can compress the volume of the raw material 800. According to a specific embodiment of the present invention, the pelletizer 1 can compress the volume of the raw material 800 to one-tenth of its original volume. The raw material 800 can be construction or industrial waste, such as wire, wood, sawdust, polystyrene, fiber, clay, etc. The pelletizer 1 includes a feeding module 10, a pressurizing zone 20, a pressurizing module 30, a conveying module 40, a power module 50, and a control module 60. The feeding module 10 is inclined relative to the horizontal plane, so that the feeding module 10 has a first angle θ relative to the horizontal plane, and the feeding module 10 includes a main auger 12. The pressurizing module 30 is located at a relatively inclined height above the feeding module 10 and is connected to the feeding module 10 through the pressurizing zone 20. The pressurizing module 30 includes a piston 32. The conveying module 40 includes a top opening plate 41. The power module 50 of this embodiment is a hydraulic system and is electrically connected to the control module 60. The power module 50 of this embodiment is a conventional hydraulic system. Specifically, a hydraulic system increases mechanical force through the principle of fluid mechanics. A hydraulic system includes a pump, pipelines, actuators, a storage tank, and valves. The storage tank stores a specific liquid. The pump pressurizes the liquid and then delivers it to the pipeline system. Various valves are installed on the pipelines, leading to components requiring hydraulic pressure. The valve controls the flow rate, pressure, and direction of the liquid in the pipeline. One end of the pipeline is an actuator that generates force; however, it should be noted that the hydraulic system is existing technology and not the focus of this invention's improvement, therefore its operational details are not described here. Furthermore, to make the key improvements of this invention clearer in the illustrations, details of the pump, pipeline, actuator, reservoir, and valve of a conventional hydraulic system are not shown in the figures. However, those skilled in the art should understand how the pump, pipeline, actuator, reservoir, and valve of a hydraulic system connect to the components requiring hydraulic pressure and transmit force.

In this embodiment, the power module 50 can be further divided into a feeding module hydraulic drive system 51, a pressurizing module hydraulic drive system 52, and a conveying module hydraulic drive system 53. The feeding module hydraulic drive system 51, the pressurizing module hydraulic drive system 52, and the conveying module hydraulic drive system 53 all include the aforementioned components such as pumps, pipes, actuators, storage tanks, and valves. The feeding module hydraulic drive system 51 drives the main auger 12 in the feeding module 10 to rotate, thereby conveying the raw material 800 to the pressurizing zone 20. After the raw material 800 accumulates to a certain quantity in the pressurizing zone 20, the hydraulic drive system 52 of the pressurizing module drives the piston 32 of the pressurizing module 30 to compress the raw material 800 into the compressed material 900. The hydraulic drive system 53 of the conveying module drives the top opening plate 41 of the conveying module 40 to move relative to the discharge port 34 of the pressurizing module, so that the compressed material 900 can be released from the granulator 1.

As shown in Figures 1, 2, and 7, the feeding module 10 receives raw material 800. The feeding module 10 includes a feeding box 11, a main screw 12, a secondary screw 13, two flaps 14, a feeding module drive 15, a feeding module outlet 16, multiple detectors 17, four spray elements 18, and a heating plate 19. The feeding box 11 is a rectangular box for the user to put in the raw material 800. In this embodiment, the feeding box 11 has an inclination θ relative to the horizontal surface. That is, as shown in Figure 1, the feeding box 11 in this embodiment is set with the left side lower and the right side higher, so that the operator can pour the raw material 800 from the lower position of the feeding box 11. The main auger 12 includes a helical blade 121, which is helically arranged along the shaft of the main auger 12. When the main auger 12 rotates, the helical blade 121 moves the raw material 800 in the feed box 11 to the feed module outlet 16. The auxiliary auger 13 has the same shape as the main auger 12 and is arranged parallel to the main auger 12. The auxiliary auger 13 is used to move the raw material 800 in the feed box 11 to near the feed module outlet 16 when it rotates. Two flaps 14 are located above the main screw 12 and the auxiliary screw 13, respectively, and are connected to the feed box 11. When the two flaps 14 rotate, they can move the raw material 800 in the feed box 11, so that the raw material 800 stacked in the feed box 11 is loosened and evenly distributed, making it easier for the main screw 12 and the auxiliary screw 13 to move. The feed module drive 15 is a hydraulic motor, which drives the main screw 12, the auxiliary screw 13, and the two flaps 14. A plurality of detectors 17 are electrically connected to the control module 60 and are used to operate the main screw 12, the auxiliary screw 13, the two flaps 14, and the plurality of detectors 17. The feed module outlet 16 is an approximately elliptical opening that connects to the pressurization zone 20. Its approximately elliptical shape facilitates the removal of the raw material 800 entangled on the main screw 12 and the auxiliary screw 13. It should be noted that the hydraulic motor is existing technology and not the focus of this invention; therefore, its operational details are not described here.

Multiple detectors 17, such as infrared sensors, are installed in the feed box 11. The multiple detectors 17 are electrically connected to the control module 60 and are used to irradiate light along a specific height and sense whether the light is blocked by an object. This allows the detector to detect whether the amount of raw material 800 in the feed module 10 has reached a specific threshold, requiring the lifting plate 14 to assist in loosening the raw material 800. If the plurality of detectors 17 detect that the amount of raw material 800 in the feeding module 10 has reached a certain threshold, the plurality of detectors 17 send a full load message to the control module 60, the control module 60 sends a full load message to the power module 50, and the power module 50 causes the feeding module drive 15 to rotate the two flaps 14 according to the full load message, so that the raw material 800 stacked in the feeding box 11 is loosened and evenly distributed, and becomes easier to be moved by the main screw 12 and the auxiliary screw 13; however, the type of detector 17 is not limited to an infrared sensor, and it can also be other components with a weight detection function. Four spray nozzles 18 are disposed in the feed box 11 and are used to spray adhesive onto the raw material 800 inside the feed module 10. For example, if the raw material 800 is sawdust, the spray nozzles 18 can be designed to spray an adhesive formed by a mixture of starch and water, so that the sawdust binds into larger granules or blocks for subsequent pressing. However, the number of spray nozzles 18 is not limited to four; it can be more than one depending on design requirements, and the type of adhesive is not limited to the above; it can also be other adhesives. A heating plate 19 is disposed at the bottom of the feed box 11 and is used to heat the raw material 800 inside the feed module 10 to soften the raw material 800, such as thermoplastic plastics.

As shown in Figures 3, 4, and 7, the pressurization zone 20 receives raw material 800 conveyed from the feed module outlet 16. The pressurization module 30 is located on one side of the feed module 10 and is connected to the feed module 10 through the pressurization zone 20. The pressurization module 30 includes a tube 31, a piston 32, a pressurization module outlet 34, and a pressurization module drive 35. The tube 31 surrounds the pressurization zone 20. The piston 32 is located below the pressurization zone 20. The pressurization module outlet 34 is located at one end of the tube 31 and is used to allow material to exit from the tube 31. The pressurizing module driver 35 is a hydraulic motor connected to piston 32 to drive piston 32 to rise or fall in the opposite direction of rising direction C within the tube 31; in this way, the rising piston 32 can squeeze the raw material 800 within the pressurizing zone 20, so that the raw material 800 is compressed into compressed material 900.

As shown in Figures 1, 4 to 7, the conveying module 40 is connected to the pressurizing module 30 and is used to convey the compressed material 900 to the external storage box 700. The conveying module 40 includes a top opening plate 41, a conveying channel 42, and a conveying module drive 43. The top opening plate 41 is located at the pressurizing module outlet 34 and is used to open or close the pressurizing module outlet 34, presenting a closed state A or an open state B. The top opening plate 41 has a slope 411, which functions as a cutter to cut the compressed material 900. A conveyor channel 42, such as a conveyor belt, is located beside the pressurizing module outlet 34 and is used to convey the compressed material 900 to the storage box 700. A conveyor module drive 43, such as a hydraulic motor, is connected to a top opening plate 41 and is used to drive the top opening plate 41 to move in the opening direction D, thus opening the pressurizing module outlet 34 to state B, or to drive the top opening plate 41 to move in the closing direction E, thus closing the pressurizing module outlet 34 to state A.

The power module 50 is a hydraulic system connected to the main screw 12, auxiliary screw 13, pressurizing module 30, and conveying module 40 of the feeding module 10, and provides hydraulic power to drive the feeding module 10, pressurizing module 30, and conveying module 40. The control module 60 is a computer host, electrically connected to the feeding module 10, pressurizing module 30, conveying module 40, and power module 50, and can be operated by personnel to control the operation of the feeding module 10, pressurizing module 30, conveying module 40, and power module 50. The control module 60 further includes a pressure detector 61, which is a pressure gauge used to detect whether the pressure within the pressurized zone 20 reaches a pushing pressure.

When the staff wants to recycle the waste material 800, they can put the material 800 into the feed box 11 of the feed module 10. The rotating main screw 12 and auxiliary screw 13 will drive the material 800 towards the pressurization zone 20. The material 800 will pass through the feed module outlet 16 to enter the pipe 31 and the pressurization zone 20. If the multiple detectors 17 detect that the amount of raw material 800 in the feed box 11 of the feed module 10 has reached a certain threshold, the multiple detectors 17 will send a full load message to the feed module driver 15, causing the feed module driver 15 to rotate the two flaps 14 according to the full load message, so that the raw material 800 piled in the feed box 11 is loosened and evenly distributed, and becomes easier to be moved by the main screw 12 and the auxiliary screw 13. If the raw material 800 is a granular or powdery substance (such as sawdust), the operator can also operate the control module 60. The control module 60 controls the sprayer 18 of the feeding module 10 to spray an adhesive formed by a mixture of starch and water, causing the raw material 800 to bind into larger granules or blocks for subsequent pressing. Alternatively, if the raw material 800 is a material that softens when heated, the operator can also operate the control module 60. The control module 60 controls the heating element 19 of the feeding module 10 to heat the raw material 800 within the feeding module 10, softening it for easier subsequent pressing.

After the raw material 800 enters the tube 31 and the pressurization zone 20, the piston 32 will first descend slightly to make the distribution of the raw material 800 in the tube 31 and the pressurization zone 20 more uniform and relaxed. At this time, the top opening plate 41 moves to cover the pressurization module outlet 34 so that the pressurization module outlet 34 is in a closed state A. Then, the raw material 800 in the pressurization zone 20 is pushed and pressurized by the piston 32 towards the top opening plate 41, so that the raw material 800 is pressed into compressed material 900. When piston 32 pushes the raw material 800 inside pipe 31 toward the top opening plate 41, pressure detector 61 detects whether the pressure in pressurized zone 20 reaches a pushing pressure. In this embodiment, the pushing pressure is 260 kg. If the pushing pressure is reached, control module 60 controls piston 32 of pressurized module 30 to maintain this pressure for a period of time (e.g., 3 seconds) to squeeze out water from the raw material 800. The squeezed water flows down pipe 31 to the bottom, where workers can then remove the wastewater. However, the values of pushing pressure and pressing time are not limited to the above and can be changed according to the type of raw material required.

After the raw material 800 is pressed into compressed material 900, the piston 32 will drop slightly for 3 to 4 seconds to allow more space around the outlet 34 of the pressurizing module. Then, the top opening plate 41 moves along the opening direction D to make the outlet 34 of the pressurizing module open B, and the piston 32 rises until the compressed material 900 moves through the outlet 34 of the pressurizing module. When the compressed material 900 moves to pass through the outlet 34 of the pressurizing module, the top opening plate 41 moves along the closing direction E until the outlet 34 of the pressurizing module is in a closed state A, and the compressed material 900 is moved to the conveying channel 42; finally, the compressed material 900 on the conveying channel 42 is transported to the collection box 700. Actual measurements show that after the pelletizer 1 of this invention compresses the raw material 800 into compressed material 900, the volume is reduced to one-tenth, and the compressed material 900 is a cubic block that can be recycled and used in the construction industry or other industrial applications, thus achieving environmental protection.

Please refer to Figures 8 through 12 below for the granulator of the second embodiment of the present invention. Figure 8 is a schematic diagram of the granulator of the second embodiment of the present invention. Figure 9 is a schematic diagram of the screen plate of the second embodiment of the present invention. Figure 10 is a cross-sectional view of the raw material being pushed through the screen plate by the granulator in the second embodiment of the present invention. Figure 11 is a schematic diagram of the moving plate shredding the raw material to form granular compressed material in the second embodiment of the present invention. Figure 12 is a system architecture diagram of the granulator of the second embodiment of the present invention.

As shown in Figures 8 to 12, the difference between the second embodiment and the first embodiment is that, in the granulator 1a of the second embodiment, the conveying module 40a further includes a screen plate 44, a moving plate 45, a moving plate drive 46, and a pusher 47. The screen plate 44 is a flat plate that includes a plurality of holes 441. The screen plate 44 covers the discharge port 34 of the pressurizing module, and the plurality of holes 441 are used for the raw material 800a to pass through. The moving plate 45 is located above the plurality of holes 441. The moving plate drive 46 is a rotary motor that is connected to the moving plate 45 and used to rotate the moving plate 45. After the raw material 800a passes through the plurality of holes 441, the rotating moving plate 45 cuts the raw material 800a to form a plurality of granular compressed material 900a. The pusher 47 is a flat plate located beside the screen plate 44 and connected to the conveyor module drive 43, used for lateral movement to move the granular compressed material 900a onto the conveyor channel 42.

When workers need to recycle waste raw material 800a (such as sawdust or clay) to form granular compressed material 900a, the raw material 800a can be put into the feeding module 10, which will send the raw material 800a into the pressurizing module 30. The piston 32 will rise and push the raw material 800a against the screen plate 44. As the raw material 800a passes through the plurality of holes 441, it will form an elongated shape. Then, the rotating moving plate 45 will cut the raw material 800a passing through the holes 441 to form granular compound compressed material 900a. Finally, the pusher 47 moves laterally to move the granular compound compressed material 900a onto the conveyor channel 42, so that the conveyor channel 42 can transport the compressed material 900a to the outside.

The granulator of this invention allows for the low-cost processing and recycling of waste raw materials. It extracts moisture from the waste materials and compresses them into cubic or granular compressed material. This compressed material is reduced to one-tenth of its original volume for easier handling and storage. Furthermore, the compressed material can be recycled and used in the construction or industrial sectors, thus achieving environmental benefits.

It should be noted that the above are merely embodiments, not limitations thereof. Anything that does not depart from the basic framework of this invention should fall within the scope of the rights claimed by this patent, and the scope of the patent application shall prevail.
