The temperature sensor 210 indicates the temperature inside the vessel 100. The temperature sensor 210 can confirm an appropriate temperature necessary for stirring the raw material. In addition, the lid 200 may be provided with a transparent window 220 that can identify the interior of the container 100. The lid 200 may be formed with a raw material input port 230 into which raw materials are input. A plurality of raw material input ports 230 may be formed.

The raw material supply member 300 can introduce the raw material into the container 100. Referring to FIG. 2, the raw material supply member 300 may include a raw material supply pipe 310 and a pump 320.

The raw material supply pipe 310 may be installed in the raw material input port 230 formed in the lid 200. A plurality of raw material supply pipes 310 may be formed corresponding to the raw material input ports 230.

The pump 320 may be installed in the raw material supply pipe 310 to supply the raw material into the container 100.

The first stirrer 410 may rotate clockwise or counterclockwise. For example, the first stirrer 410 may rotate clockwise. The first agitator 410 may include a plurality of first agitating blades 411. The plurality of first stirring vanes 411 may be provided along the vertical direction of the container 100. The first stirring blades 411 may be spaced apart from each other by a predetermined distance.

The second agitator 420 may rotate clockwise or counterclockwise. For example, the second agitator 420 may rotate in the direction opposite to the direction in which the first agitator 410 rotates. The second agitator 420 may include a plurality of second agitating blades 421. The plurality of second stirring vanes 421 may be provided along the vertical direction of the container 100. Each of the second stirring blades 421 may be disposed between the plurality of first stirring blades 411.

Accordingly, a vortex phenomenon may occur in the interior of the container 100 due to the first agitator 410 and the second agitator 420 rotating in opposite directions. Therefore, the raw material inside the container 100 can be uniformly mixed.

Referring to FIG. 1, the cleaning unit 430 may rotate along the inner wall 120 of the vessel 100. The cleaning unit 430 may include a projection 431 that contacts the inner wall 120 of the container 100.

The pressure reducing pipe 510 may be connected to the air outlet 130 of the container 100.

The pump 520 may be provided as a vacuum pump. The pump 520 may be installed in the decompression pipe 510 to suck air inside the container 100 to maintain the inside of the container 100 at a reduced pressure lower than the normal pressure. Accordingly, the boiling point of the raw material is lowered due to the pressure inside the lowered vessel 100, and damage due to heat load and heat load can be reduced. Further, the bonding force between the raw material and the base oil can be improved. In addition, since the raw material reacts at a low temperature due to the reduced pressure state below the atmospheric pressure, consumption of raw materials can be reduced.

The measuring unit 600 may be installed in the container 100 to measure the weight of the container 100. The measuring unit 600 can measure the weight of the container 100 in real time according to the change in the volume of the raw material supplied into the container 100. The measuring unit 600 may be provided with a display in which the weight of the container 100 is displayed in real time.

The control unit 700 can control the raw material supply member 300, the agitator 400, the pressure reducing member 500, and the measuring unit 600.

The control unit 700 may drive the decompression member 500 to lower the internal pressure of the hermetically sealed container 100. That is, the controller 700 can produce the grease by stirring the raw material while maintaining the internal pressure of the vessel 100 at a reduced pressure lower than the atmospheric pressure at the time of manufacturing the grease. The control unit 700 can stir the raw material by driving the stirrer 400. [ The control unit 700 can measure the weight of the container 100 using the measuring unit 600 during stirring of the raw material. The control unit 700 may control the raw material supply member 300 to drive the raw material into the container 100 when the measured weight of the container 100 falls below a predetermined weight. That is, the grease can be produced without stopping the stirring in a state in which the raw material above the set amount is always maintained in the vessel 100.

The lifting and lowering portion 800 can move the lid 200 up and down. Conventionally, a creel lift system is used to move up and down the lid 200. However, the crane lift system was connected to the outside line, and vibration occurred, and the stirrer was damaged. In addition, the load that can be sustained was also low. 3 to 4, the ascending and descending portion 800 may be formed of a hydraulic cylinder 810, a first support member 820, and a second support member 830.

The hydraulic cylinders 810 may be formed on both sides of the container 100, respectively.

The first support member 820 supports the lifting and lowering motion of the hydraulic cylinder 810 and guides the lifting and lowering lid 200 of the lid 200 so that the vertical height of the lid 200 can be precisely adjusted.

The second support member 830 is connected to the lid 200 and can move up and down according to the movement of the hydraulic cylinder 810 up and down.

The ascending and descending portion 800 can support a larger load than the conventional creel lift method. The ascent / descent part 800 supports the lid 200 on both sides and can move up and down. Since the ascending and descending portion 800 is supported on both sides, the occurrence of vibration can be minimized. The ascending and descending portion 800 descends the lid 200 and provides the lid 200 to seal the inside of the container 100 completely.

The rotary motor 900 can rotate the stirrer 400 clockwise or counterclockwise. The rotary motor 900 may include a rotary shaft 910 connected to the stirrer 400.

The manufacturing method using the above-described grease-reduced manufacturing apparatus 10 will be described in detail.

5 is a flowchart showing a method of manufacturing a reduced-pressure grease according to an embodiment of the present invention.

Referring to FIG. 5, the method for producing a reduced-pressure grease includes a sealing step S100, a first raw material supplying step S200, a depressurizing step S300, a stirring step S400, a weighing step S500, (S600).

The closing step S100 is a step of lowering the lid 200 with the lifting and lowering part 800 and sealing the lid 200 completely inside the container 100. [ The first raw material applying step (S200) is a step of driving the raw material supplying member (300) and injecting the raw material into the hermetically sealed container (100). The depressurization step S300 is a step of driving the depressurizing member 500 to lower the pressure inside the container 100 to a depressurized state lower than normal pressure. At this time, the pressure inside the lowered vessel 100 lowers the boiling point of the raw material, so that the damage due to heat load and heat load can be reduced. Further, the bonding force between the raw material and the base oil can be improved. In addition, since the raw material reacts at a low temperature due to the reduced pressure state below the atmospheric pressure, consumption of raw materials can be reduced. The stirring step (S400) is a step of stirring the raw material by driving the stirrer (400). At this time, the first and second stirrers 410 and 420 rotate in the clockwise direction and the counterclockwise direction, respectively, so that the swirling phenomenon may occur. Thus, mixing of the raw materials can be made more smooth. The weight measuring step S500 is a step of measuring the weight of the container 100 in real time using the measuring unit 600 during stirring. The second raw material applying step S600 is a step of driving the raw material supplying member 300 to feed the raw material into the container 100 when the measured weight of the container 100 falls below a predetermined weight. At this time, the charged raw material is introduced into the vessel 100 through the raw material supply pipe 310, so that the grease can be produced while the pressure inside the vessel 100 is maintained at a reduced pressure lower than the atmospheric pressure.

Accordingly, conventionally, when the raw material is consumed while producing the grease under a reduced pressure lower than the normal pressure, the pressure inside the vessel 100 is returned to the normal pressure state and then the raw material is supplied into the vessel 100, there was.

However, the apparatus for producing a reduced-pressure grease according to the present invention is capable of continuously supplying the consumed raw material to the inside of the vessel 100 without stopping the agitator 400 while maintaining the internal pressure of the vessel 100 at a reduced pressure lower than the atmospheric pressure, can do.

That is, the stirrer 400 can be driven continuously without interruption until it meets a predetermined production amount. Therefore, the weight measuring step (S500) and the second raw material applying step (S600) may be repeatedly performed.

The foregoing detailed description is illustrative of the present invention. In addition, the foregoing is intended to illustrate and explain the preferred embodiments of the present invention, and the present invention may be used in various other combinations, modifications, and environments. That is, it is possible to make changes or modifications within the scope of the concept of the invention disclosed in this specification, within the scope of the disclosure, and / or within the skill and knowledge of the art.
