Description

A garbage sorting and recycling device

The invention relates to a garbage processing machine, more particularly to a garbage sorting and recycling device.

With the continuous development of urban construction, garbage disposal is an increasingly important issue. Due to the many components of garbage, in order to recycle or process, it is necessary to sort the garbage, and separate out construction waste, plastics, ferromagnetic substances, organic substances, etc. for recycling.

The object of the present invention is to provide a garbage sorting and recycling device, which can effectively sort garbage for separate treatment or recycling.

In order to achieve the above object, a garbage sorting and recycling device of the present invention includes a garbage crusher, a vibrating screen, a fan, a sorting machine, a magnetic separator and a belt conveyor. The garbage crusher is arranged below the garbage inlet. The vibrating screen is located under the garbage crusher to screen the garbage. A first belt conveyor is located below the front end of the vibrating screen to receive the oversize, and a blower fan is installed at the outlet of the belt conveyor to air-select the oversize. A second belt conveyor is located under the vibrating screen and is used to receive and transport the underscreen, and along its travel path on the second belt conveyor, a sorter for sorting light materials and a sorter for sorting out iron are arranged in sequence. Magnetic separator for magnetic substances.

Using the garbage sorting and recovery device of the present invention, the garbage is first crushed by the crusher, and then screened by the vibrating screen. The large pieces of construction waste are sent to the distribution center by the first belt conveyor for processing, and the broken garbage is continuously transported by the second belt conveyor. Sorting is carried out by sorting machine and magnetic separator, and the remaining shredded garbage can be suitable for fermentation treatment.

In order to better understand and understand the present invention, a preferred embodiment will be described in detail below with reference to the accompanying drawings.

Fig. 1 is the schematic diagram of garbage sorting recovery device of the present invention;

2A and 2B are respectively an axial view and a side sectional view of the garbage crusher;

Fig. 3 is a side view and a top view of the vibrating screen;

4A and 4B are respectively an axial view and a side view of the sorting machine.

Referring to Fig. 1, device of the present invention mainly comprises rubbish breaker, vibrating screen, separator, magnetic separator and belt conveyor.

The fresh garbage contained in the hopper 2 is transported to the top of the garbage crusher by belt conveyors 1, 3, 7 and falls, and is crushed by the crusher. The crusher mainly includes an elastic knife 10, an isolating ring 9, a stripping sleeve 11 and an elastic feeding device 8.

The vibrating screen 6 is located below the crusher to receive the rubbish falling from the crusher. The exciter 5 makes the vibrating screen 6 reciprocate horizontally.

A first belt conveyor 13 is arranged under the front end of the vibrating screen 6 to send the slid down large pieces of sieve to the distribution center, and a fan 12 performs air selection on it at the discharge port to separate light materials such as plastics. quality matter.

A second belt conveyor 4 is located below the vibrating screen 6 to receive the undersize and transport it to the right.

A separator and a magnetic separator 17 are provided in sequence along the travel path of the second belt conveyor 4 . The sorting machine mainly includes a fan 16 , a sorting device 15 and a conveying pipe 14 . The sorting machine sorts out light substances such as plastic bags and sends them into the conveying pipe 14 . The magnetic separator 17 sorts out ferromagnetic substances. Remaining shredded rubbish is sent to fermentation bin by belt conveyor 18 for fermentation.

Referring to Fig. 1, one end of the elastic feeding device 8 of the garbage crusher is hinged, and the other end is supported by a spring. The elastic feeding device 8 is used to slow down the falling of garbage and control the crushing force.

Please refer to Fig. 2A and 2B again, the crusher comprises a high-speed rotating shaft 19, and four rows of elastic knives 10 are housed on it, and the elastic knives are made by twisting 90° of spring steel plates, and its near-axis section has circumferential elasticity, and the far-axis section has circumferential elasticity. In this way, when the knife edge encounters a hard object, the elastic section of the knife body allows the knife edge to deform elastically in the circumferential direction, so as to reduce the dynamic load and prevent the early damage of the knife edge. The spacer ring 9 is tangentially welded to the eccentric stripping sleeve 11 and fixed on the frame (not shown). The isolation ring 9 is concentric with the circle of revolution of the crushing knife (ie elastic knife). The function of the spacer ring 9 is: when the elastic knife 10 encounters a hard object, it will not deflect axially, and can accurately enter the circumferential slit 20 of the eccentric stripping sleeve 11 when rotating. The circumferential slits 20 of the stripping sleeve 11 correspond to the positions of the elastic knives 10 of each layer, and are opened along a circumferential direction of 180°. The width of the slit is slightly larger than the thickness of the elastic knife. When the knife edge turns out to work along the narrow slit, due to the eccentric effect, when the knife edge retracts into the narrow slit, the flexible material wrapped on the knife edge is scraped off by the narrow slit.

It can be seen from Fig. 3 that the screen surface of the vibrating screen 6 is a strip-shaped screen gap.

4A and 4B again, the sorting device 15 includes a low-speed rotating shaft 25, on which a plurality of rows of elastic teeth 26 are housed. material segment. The outlet of fan 16 is a flat air slot, and the wind bundle is a flat rectangular wind bundle, and the wind direction is blown into the sorting material conveying pipe 14 through the rotating shaft 25 below. The wind speed and air volume of the wind beam are adjustable, and the rotation speed of the rotating shaft is adjustable. When the sorting device 15 rotates clockwise, the elastic teeth 26 can pick up light substances such as plastic bags, and the fan 16 blows these substances into the conveying pipe 14 .
