Detailed Description of the Invention

[0033] The present invention will be further described below in conjunction with specific embodiments and the drawings.

[0034] Figures 1 to 3A solid waste recycling and treatment device is presented, including a crushing chamber 200. An inlet 100 is provided at the upper end of the crushing chamber 200, and an outlet 210 is provided at the lower end. A crushing roller set is arranged in the crushing chamber 200. The crushing roller set includes two crushing roller bodies 300 with differential speed settings. By the double-roller differential rotation, the double superposition of shearing and tearing forces is realized, which not only improves the crushing efficiency but also prevents the entanglement of ductile materials.

[0035] The specific method of the differential crushing roller set is as follows: One end of the crushing roller body 300 of the crushing roller set is provided with a driving gear 350 and a driven gear 340, and a differential gear set 360 is in transmission cooperation between the driving gear 350 and the driven gear 340.

[0036] In order to protect the above gear set and prevent potential safety hazards, a protective box cover 700 fixedly installed on the outer wall of the crushing chamber 200 is provided for the driving gear 350, the driven gear 340, and the differential gear set 360.

[0037] A dust suction channel 220 is arranged inside the inlet of the crushing chamber 200. The dust suction channel 220 is provided with a plurality of dust suction ports 230 communicating with the crushing chamber 200, and filter nets are arranged at the dust suction ports 230. At the same time, at least one of the crushing roller bodies 300 of the crushing roller set is hollow, and a negative pressure channel 313 is arranged inside it. A negative pressure guide vane 320 is arranged in the negative pressure channel 313, which is used to generate negative pressure as the crushing roller body 300 rotates, so as to prevent dust from overflowing.

[0038] The inlet end of the negative pressure channel 313 is communicated with the dust suction channel 220, and the outlet end of the negative pressure channel 313 is communicated with a dust collection box 600. A filter bag air outlet 620 is arranged at the top of the dust collection box 600. The dust collection box 600 can be integrally arranged with the crushing part or can be arranged as a split type, and both have their own advantages. The integral type has good integrity and can also save some space, while the split type is more convenient for replacement and personalized layout. In this embodiment, the split type is taken as an example. The inlet 100 is arranged as a hopper module, and the hopper module and the crushing chamber 200 are detachably and hermetically connected; the outlet end of the negative pressure channel 313 is detachably and hermetically connected with the dust collection box 600.

[0039] The connection structure at both ends of the crushing roller body 300 is as follows: The inlet end of the negative pressure channel 313 is provided with an air inlet cylinder shaft 310, and the outlet end of the negative pressure channel 313 is provided with an air outlet cylinder shaft 330. The air inlet cylinder shaft 310 and the air outlet cylinder shaft 330 are respectively communicated with the dust suction channel 220 and the dust collection box 600 through corresponding rotary connectors 500 and pipelines. The function of the rotary connector 500 is to realize the rotational connection. The existing technology is very mature and is very easy to achieve. The existing technology can be adopted and will not be elaborated here.

[0040] In order to facilitate regular dust cleaning and prevent the suction flow channel 220 from being blocked, the intake cylinder shaft 310 is fixedly and sealingly connected to the external diversion pipe 400 through a rotary connector 500, and the other end of the external diversion pipe 400 is fixedly and sealingly connected to the air outlet hole of the suction flow channel 220. The protective box cover 700 is provided with a mating hole 710 adapted to the external diversion pipe 400.

[0041] In order to ensure that the crushing roll main body 300 does not affect the rotational connection stability with the external diversion pipe 400, a support 510 for installing and fixing the rotary connector 500 and the external diversion pipe 400 is fixedly installed on the outer side wall of the crushing chamber 200.

[0042] In order to ensure the smooth installation of the gear set, a connection end 311 is provided at the end of the intake cylinder shaft 310. The connection end 311 is provided with a flange for sealing connection with the rotary connector 500, and the maximum outer diameter of the flange is less than or equal to the outer diameter of the intake cylinder shaft 310. In this way, stable flange connection can be achieved without interfering with the installation of the gear set.

[0043] The negative pressure diversion vane 320 can be integrally provided with the crushing roll main body 300 or can be selectively provided in a split type. The advantage of the split type is that it is convenient for replacement and maintenance. By selecting negative pressure diversion vanes 320 of different specifications, the required negative pressure magnitude can be generated, and the negative pressure can be adjusted, having better adaptability.

[0044] In order to achieve the detachable installation of the negative pressure diversion vane 320, one end of the negative pressure channel 313 is provided with a detachable end cover, and the intake cylinder shaft 310 and its connection end 311 are both arranged on the end cover;

[0045] The intake cylinder shaft 310 is provided with an installation sleeve 312 with a coincident central axis, and the negative pressure diversion vane 320 is provided with an installation shaft head 321 adapted to the installation sleeve 312.

[0046] In order to stably fix the installation sleeve 312 to achieve the stable installation of the negative pressure diversion vane 320 and reduce the influence on the operation of the negative pressure air flow, the installation sleeve 312 is installed and fixed in the intake cylinder shaft 310 at intervals through a plurality of support plates 314.

[0047] The bottom of the dust collection box 600 is provided with a detachable and sealingly connected dust discharge port 610, which is convenient for receiving and discharging the dust of the mobile phone;

[0048] The working principle and process of the solid waste recycling and treatment device are as follows: negative pressure is generated by the movement of the crushing roller itself, specifically, the rotation of the negative pressure guide vane generates negative pressure at the entrance of the crushing chamber 200. The negative pressure guide vane 320 can be set to a structure similar to the impeller of a centrifugal fan, or it can be set to a spiral guide vane. When rotating, the airflow on one side of the negative pressure channel 313 can be transported to the other side, so that the transported airflow is discharged from the crushing chamber 200 to generate negative pressure. Then, negative pressure is generated in the entrance part of the crushing chamber 200 that is connected to the negative pressure channel 313 through the dust suction channel 220 and the dust suction port 230, so as to suppress dust overflow. At the same time, the negative pressure attracts dust along with the airflow through the dust suction port 230, the dust suction channel 220, the external guide tube 400, the negative pressure channel 313, and then enters the dust collection box 600 to complete dust collection.

[0049] The solid waste recycling and processing device achieves multi-functional integration by combining the crushing function with the negative pressure generation. It not only prevents the dust from overflowing during the crushing process, but also significantly reduces the energy consumption of the overall system, making it more efficient, environmentally friendly and easy to maintain when processing complex waste (such as waste tires, electronic waste, textiles, etc.), solving many technical problems existing in traditional crushing equipment.

[0050] In summary, the device includes a crushing chamber 200, a crushing roller group with a differential setting, and a self-generated negative pressure dust removal system. The crushing roller group realizes the double superposition of shear and tearing forces through the differential rotation of the double rollers, effectively preventing the entanglement of tough materials and improving the crushing efficiency. The crushing roller body 300 is hollow in design, with a built-in negative pressure guide blade 320, which generates negative pressure during rotation to inhibit dust overflow. The dust suction channel 220 is connected to the negative pressure channel 313, and the dust is collected into the dust box 600 with the airflow to reduce environmental pollution. The device adopts a modular design, and the components are detachably sealed and connected for easy maintenance and cleaning. The protective box cover 700 protects the gear set to ensure safe operation. This equipment not only solves the problem of entanglement that is prone to occur when traditional crushing equipment processes high-fiber or tough materials, but also achieves efficient dust removal and energy-saving effects. It is suitable for the treatment of various solid wastes such as waste tires and electronic waste.
