Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and aggregation of plastic particles, in particular to a device for dust removal and aggregation of plastic particles. Background Art

[0002] Plastic particles, also known as plastic particles or resin particles, are the basic raw materials for making plastic products. Plastic particles are usually solid granular structures made of a specific type of plastic resin.

[0003] During the production process, plastic particles are generally extruded into a granular structure using an extruder.

[0004] The specific production and processing principle is to put the plastic raw material into the feeding hopper of the extruder, then pass through the screw and heat in the extruder, and finally cool and extrude it into granular plastic particle products through the extruder head.

[0005] At present, during the extrusion molding process of existing plastic particles in an extruder, fine plastic raw material particles will be generated. These fine plastic raw material particles will fly directly in the production workshop through the feeding hopper and finally fall to the ground, thereby causing waste of these fine plastic raw material particles.

[0006] In addition, during the extrusion process of existing plastic particles in the extrusion device, harmful waste gas will be generated. These harmful waste gases will fly directly into the production workshop through the feeding hopper. If the operator inhales them directly, it will cause harm to his health.

[0007] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-5 A plastic particle dust collection device comprises a dust collection box 1, an extrusion device 2 is provided below the dust collection box 1, a filter housing 7 and a telescopic material pipe 41 are provided on the dust collection box 1, a feeding hopper 21 and an extrusion head 22 are provided on the extrusion device 2, a gear box 23 is provided at the left end of the extrusion device 2, an adjusting cylinder 3 is provided on the gear box 23, a lifting frame 31 is provided on the adjusting cylinder 3, a collection cover 32 is provided on the lifting frame 31, a connecting material pipe 4 and a discharge cover 42 are provided on the telescopic material pipe 41, a fixed block 5 is provided on the dust collection box 1, a positioning column 6 is slidably connected on the fixed block 5, a storage tank 73 and a dust filter element 74 are provided on the filter housing 7, a suction pump 8 is provided on the extrusion device 2, the extrusion device 2, the feeding hopper 21, the extrusion head 22, and the gear box 23 are all related structures on the plastic particle extrusion production equipment, which are prior art. Some existing structures are not drawn and marked, and there is no need to repeat them.

[0029] The interior of the aggregate sealing cover 32 is a hollow cavity and is connected to the connecting material pipe 4. The circular cross-sectional size of the inner cavity of the aggregate sealing cover 32 when viewed from above is not smaller than the circular cross-sectional size of the inner cavity of the feeding hopper 21 when viewed from above, and has a sealing covering effect to avoid air leakage during the suction and aggregation process.

[0030] The telescopic material pipe 41 is made of a bellows material and is fixedly welded and penetrated on the dust collection box 1. The upper end of the telescopic material pipe 41 is fixedly welded to the connecting material pipe 4. The discharge cover 42 is a downward diffusion structure as a whole. When the regulating cylinder 3 drives the collection cover 32 to move up and down, the telescopic material pipe 41 itself will vertically expand and contract and deform, which will not affect the extraction and collection of materials.

[0031] The top view cross-section of the storage tank 73 is a rectangular inner tank that is open upward. The dust filter element 74 is embedded in the storage tank 73 and is not higher than the storage tank 73. It can block fine plastic raw material particles and aggregate and store them in the storage tank 73.

[0032] The dust filter element 74 is made of activated carbon, is durable, and can filter and purify harmful exhaust gas contained in fine plastic raw material particles.

[0033] A sealing opening 11 and a sealing slot 12 are provided on the dust collection box 1, and the filter housing 7 passes through the sealing opening 11 and is squeezed and plugged into the sealing slot 12. Sealing gaskets are provided on the inner walls of the sealing opening 11 and the sealing slot 12, which have high elastic sealing properties to ensure the sealing between the filter housing 7 and the dust collection box 1 after installation.

[0034] A finger buckle groove 71 and a positioning groove 72 are provided on the filter housing 7, and the positioning column 6 is snap-fitted into the positioning groove 72. A pull plate 61 is provided on the positioning column 6, and a spring 51 is provided between the pull plate 61 and the fixed block 5. When the pull plate 61 is pulled upward and drives the positioning column 6 to exit the positioning groove 72, the spring 51 is stretched and deformed. When the finger no longer pulls the pull plate 61, the spring 51 pulls back and drives the positioning column 6 to quickly snap downward into the positioning groove 72, thereby facilitating the positioning and snap-fitting installation of the filter housing 7.

[0035] A suction pipe 81 and an exhaust pipe 82 are respectively provided at both ends of the suction pump 8. The suction pipe 81 is connected to the inner cavity of the dust collecting box 1. The suction pump 8 is a powerful air pump to ensure the suction and collecting effect.

[0036] Working method: a certain amount of plastic particle raw material is put into the feeding hopper 21, and the extrusion device 2 is started to perform extrusion molding (which is the existing technology). At the same time, the regulating cylinder 3 is started to drive the collection cover 32 to move downward and seal the feeding hopper 21 as a whole, stop the regulating cylinder 3 and start the suction pump 8, the collection cover 32 will draw the fine plastic raw material particles produced by extrusion molding into the dust collection box 1 through the connecting material pipe 4 and the telescopic material pipe 41, and finally the fine plastic raw material particles will be accumulated in the storage tank 73 through the discharge cover 42 to avoid the waste of these fine plastic raw material particles flying directly through the feeding hopper 21 and falling on the ground in the production workshop.

[0037] Moreover, when the fine plastic raw material particles are sucked and stored through the aggregate cover 32, the harmful waste gas contained in the fine plastic raw material particles will also enter the dust collection box 1, and then be effectively sucked out, filtered and purified by the dust filter element 74, and finally discharged through the exhaust pipe 82, thereby preventing the harmful waste gas from directly flying into the production workshop through the feeding hopper 21 and being directly inhaled by the operator to cause health damage.

[0038] In addition, when the storage tank 73 is full of fine plastic raw material particles, one hand pulls up the pull plate 61 to drive the positioning column 6 to move upward and exit the positioning tank 72, and the other hand grabs into the finger buckle groove 71 and pulls it to the right, driving the filter housing 7 as a whole to move horizontally out of the sealing port 11, and then the fine plastic raw material particles stored in the aggregate can be conveniently poured into the storage bucket next to it for later recycling.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
