Description

Technical Field

[0001] The utility model relates to dust removal equipment for a plastic film granulator, belonging to the technical field of granulation equipment. Background Art

[0002] When recycling waste plastic, a plastic granulator heats and melts the recycled plastic raw material, extruding it into plastic strips and then cutting it into uniformly sized plastic pellets to facilitate secondary processing into finished industrial products. During the smelting and granulation of the waste plastic in the granulator, the extrusion die produces dust and debris as it cuts the plastic into pellets. This dust and debris mix with the pellets, affecting their overall quality. A search revealed that Chinese patent publication number CN205835733U discloses a dust removal device for a plastic granulator. In this patent, plastic pellets are placed between a drive roller and a nozzle. During the plastic transfer process, the edges of the plastic come into contact with the grinding wheel. As the pellets move, the nozzle 3 cleans the upper surface of the pellets, flushing away plastic powder and preventing dust from forming in the air. A low-pressure water pipe allows the sponge sleeve to absorb sufficient moisture to clean the lower surface of the pellets. However, after the water wash, the plastic pellets need to be dried or aired again to prevent clumping, which affects production efficiency. Summary of the Invention

[0030] The blowing assembly includes a blower 41 and a blowing pipe 42. The blower 41 is installed on the frame 1. One end of the blowing pipe 42 is connected to the air outlet of the blower 41, and the other end of the blowing pipe 42 faces the dust removal bin 3.

[0031] The external plastic film granulator is suitable for conveying the produced plastic particles to the first conveyor belt 23, the first conveyor belt 23 is suitable for conveying the plastic particles to the dust removal chamber 31, and the blower 41 is suitable for blowing gas into the dust removal chamber 31 to remove dust on the plastic particles in the dust removal chamber 31.

[0032] Specifically, if Figure 1-3 As shown, the dust removal equipment for the plastic film granulator further includes a second conveying assembly, which includes a third conveying roller 51, a fourth conveying roller 52 and a second conveyor belt 53. The third conveying roller 51 and the fourth conveying roller 52 are both rotatably mounted on the frame 1, and the second conveyor belt 53 is suitable for connecting the third conveying roller 51 and the fourth conveying roller 52.

[0033] The second conveying assembly is arranged below the first conveying assembly, and the dust removal outlet 33 faces the second conveying belt 53 .

[0035] In this embodiment, the first conveying assembly further includes a first drive motor, the movable end of which is connected to the first conveying roller 21. The first drive motor drives the first conveying roller 21 to rotate clockwise, thereby driving the first conveyor belt 23 to move toward the dust removal inlet 32.

[0036] The second conveying assembly further includes a second drive motor, the movable end of which is connected to the third conveying roller 51 . The second drive motor drives the third conveying roller 51 to rotate counterclockwise, thereby driving the second conveyor belt 53 to move toward the storage chamber 61 .

[0037] Specifically, if Figure 1-3 As shown, the dust removal equipment for the plastic film granulator also includes a first conveying pipe 7, which is installed on the frame 1.

[0044] In this embodiment, the plastic pellets produced by the external plastic film granulator are conveyed to the first conveyor belt 23 through the first inlet 71 of the first conveying pipe 7. The first conveyor belt 23 is driven by the first conveyor roller 21 and the second conveyor roller 22 to convey the plastic pellets forward to the dust removal bin 3. When the plastic pellets enter the dust removal chamber 31, the blower 41 is started to blow air into the dust removal chamber 31 through the blowing pipe 42, blowing off the dust attached to the surface of the plastic pellets. The dust follows the airflow through the dust removal channel 35 and is adsorbed on the dust removal bag.
