Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a waste tire rubber granulation and reuse equipment. Background Technology

[0002] In the process of recycling and reusing waste tires, crushing equipment is needed to crush the waste tires into granules.

[0003] Existing technology, patent CN208697746U, discloses a waste tire rubber crushing and sorting device, including a housing, a feed hopper at the upper end of the housing, servo motors at both ends of the housing, the output ends of the servo motors connected to a rotating shaft via couplings, a crushing roller mounted on the rotating shaft with crushing teeth on its outer surface, a servo motor mounting plate at the lower end of the servo motor, a vibrating motor installed inside the motor mounting plate, a vibrating screen plate below the crushing roller, a sorting box below the vibrating screen plate, a filter screen at the lower end of the sorting box, a partition plate below the limiting plate, a support frame at the lower end of the housing, and a collection box at the upper end of the load-bearing plate. This invention provides more uniform crushing, and waste tire rubber that is not thoroughly crushed can be poured back into the equipment for further crushing. The dual sorting process results in finer rubber material being screened out at the end.

[0004] The aforementioned patented technology generates dust during the pulverization of waste tires by two pulverizing rollers. This dust is discharged through the top of the feed hopper, polluting the environment and the equipment. Furthermore, since some waste tires contain metal objects, such as nails, the pulverized waste tires contain metal contaminants, which is detrimental to subsequent production. In other words, the patented technology has the drawback of failing to effectively remove metal objects. Therefore, this application proposes a waste tire rubber granulation and recycling device.

[0056] Specifically, by setting the guide block 800, the crushed rubber particles can fall onto the surface of the cylindrical electromagnet 502, thus achieving thorough removal of metal objects.

[0057] In this embodiment, by setting up a crushing component 400 and a screening component 500, the equipment can quickly crush waste tires during the crushing process.

[0058] Example 2

[0059] Based on Example 1, referring to Figure 1 , Figure 3 and Figure 4 The front of the shredder 100 is provided with a dust collection component 600. The dust collection component 600 includes a dust collection box 601 fixed on the lower surface of the mounting box 404 and a dust collection bag 602 disposed inside the dust collection box 601. A sealing door panel 603 is hinged to the front of the dust collection box 601, and a dust collection fan 604 is embedded in the inner bottom wall of the dust collection box 601.

[0060] Specifically, the dust collection bag 602 facilitates dust collection, while the sealing door panel 603 facilitates the replacement of the dust collection bag 602.

[0061] Reference Figure 3 and Figure 4In a preferred embodiment, a plurality of dust suction holes 605 are arranged in a circumferential array on the inner wall of a rotating cylinder 401 and a crushing roller 402, and an intercepting net 606 is provided at the end of the dust suction hole 605. A dust suction pipe 607 extending into the mounting box 404 is embedded in the inner wall of the dust collection box 601.

[0062] Specifically, by providing a dust suction hole 605, dust can be absorbed inside the crushing chamber 100 during the crushing process.

[0063] Reference Figure 3 In a preferred embodiment, the end of the suction pipe 607 away from the dust collection box 601 extends into the interior of a rotating cylinder 401, and the end of the rotating cylinder 401 is provided with a rotating hole that is rotatably connected to the outer surface of the suction pipe 607. The dust collection bag 602 is fixed to the other end of the suction pipe 607 by wire.

[0064] Specifically, by setting up a suction pipe 607, dust can be easily diverted to the dust collection bag 602 for collection.

[0065] In this embodiment, by setting up a dust collection component 600, the dust generated during the crushing process of waste tires can be effectively reduced, thus avoiding dust pollution to the environment and equipment.

[0066] Working Principle: When crushing waste tires, the equipment feeds waste tires into the crushing box 100 through the feed hopper 200. The drive motor 405 is activated, and the cylindrical electromagnet 502 is energized. The rotation of the drive motor 405 drives one rotating drum 401, which in turn drives another rotating drum 401 via two gear discs 406. This causes the two crushing rollers 402 to rotate in opposite directions, rapidly crushing the waste tires into granules that fall downwards. Under the action of the energized cylindrical electromagnet 502, the falling metal objects are effectively adsorbed, thus achieving the crushing of the waste tires. The method effectively screens and removes metal objects from tire rubber granules, making it highly practical. Furthermore, during the shredding process of waste tires, the dust extraction fan 604 can be activated to expel air from the dust collection box 601, creating negative pressure within it. At this time, the dust collection box 601 draws air from the rotating drum 401 through the suction pipe 607, creating negative pressure within the drum 401. This allows the rotating drum 401 to effectively adsorb dust generated during the shredding process through the suction hole 605, which is then collected by the dust collection bag 602. This effectively reduces dust generated during the shredding process, preventing dust pollution to the environment and equipment.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
