Description

Technical Field

[0001] This invention relates to the field of rubber crushing technology, specifically to a waste rubber pyrolysis and crushing processing equipment. Background Technology

[0002] Tires are consumables. After a period of use, the tread pattern on the tire surface gradually wears down, so tires need to be replaced regularly to ensure driving safety. To improve the reuse rate of rubber and reduce resource waste, waste tires are now centrally recycled and processed. The recycled tires are then crushed into rubber granules. Currently, waste tire recycling typically involves first removing the steel wires and then cutting the strip-shaped tire rubber into blocks using a primary crusher. These blocks are then added to a secondary crusher to further pulverize the rubber into granules. Existing secondary crushers generally use crushing rollers or high-speed rotating blades to pulverize the rubber. However, due to the high elasticity of rubber, the uniformity of the crushed material is not high. Therefore, when rubber granules of a certain size are needed, the crushed material is often screened, resulting in significant losses due to the lack of uniformity. Summary of the Invention

[0003] The purpose of this invention is to provide a waste rubber pyrolysis and crushing processing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A waste rubber pyrolysis and crushing processing device, comprising:

[0006] The base has positioning pins fixedly installed on both sides, and a drive shaft is rotatably connected to the top of the base. A drive motor is installed on the top surface of the base, and the output end of the drive motor is rotatably connected to the bottom end of the drive shaft.

[0007] There are three crushing units, which are stacked sequentially between two positioning pins. Each crushing unit includes a bearing ring, an outer shell, a conical screen, and an execution module. The bearing ring and the execution module are slidably inserted into the drive shaft, and the outer shell is slidably inserted into the two positioning pins.

[0008] The feeding hopper is located above the three crushing units and is used to feed materials into the crushing units.

[0009] The receiving hopper is located below the three crushing units. The receiving hopper is installed between two positioning pins. One side of the receiving hopper is fixedly connected to the discharge port. The receiving hopper is used to receive and discharge the processed material.

[0010] Furthermore, the transmission shaft has a rib section at its middle position, a step is provided between the rib section and the bottom end of the transmission shaft, a threaded groove is provided on the outer side wall of the top end of the transmission shaft, and a nut is screwed onto the top end of the transmission shaft.

[0011] Furthermore, the outer wall of the conical screen is frustum-shaped, the top of the conical screen converges towards the middle, and the top of the conical screen is provided with a vent hole, which is used to prevent interference between the screen and the drive shaft.

[0012] Furthermore, the inner wall of the conical screen is fixedly connected with three annular frames at equal intervals, and the bottom surface of the lowest annular frame is fixedly connected with multiple positioning blocks at equal intervals. The inner bottom surface of the outer shell is provided with multiple positioning holes at equal intervals, and the multiple positioning holes correspond to the multiple positioning blocks.

[0013] Furthermore, the execution module includes a second transmission sleeve, which is used to slide and engage with the rib portion of the transmission shaft. A mounting bracket is fixedly connected to the outer side wall of the second transmission sleeve. An arc-shaped blade is fixedly connected to one end of the mounting bracket. A cutting edge is provided at one end of the arc-shaped blade. A guide plate is fixedly connected to the side wall of one end of the arc-shaped blade.

[0014] Furthermore, a transmission sleeve is provided at the middle position of the bearing ring, the transmission sleeve is slidably sleeved with the rib portion of the transmission shaft, the inclination of the outer wall of the bottom end of the bearing ring is the same as the inclination of the conical screen, the outer diameter of the bottom end of the bearing ring is larger than the outer diameter of the bottom end of the conical screen, and an eccentric frame is fixedly connected between the transmission sleeve and the bearing ring, the transmission sleeve and the bearing ring are in an eccentric state.

[0015] Furthermore, an intermediate chamber is formed between the bearing ring and the conical screen, and an inclined pusher is fixedly connected to the inner wall of the bearing ring on the side opposite to the transmission sleeve.

[0016] Furthermore, the size of the screen holes on the plurality of conical screens decreases sequentially from top to bottom, and adjacent conical screens are staggered by 180 degrees.

[0017] Furthermore, both sides of the outer side wall of the outer casing are fixedly connected to a fixed sleeve, which is used to slide and engage with the positioning pin. The sum of the heights of the second transmission sleeve and the first transmission sleeve is the same as the height of the fixed sleeve.

[0018] Furthermore, the top of the uppermost ring in the three crushing units is fixedly connected to a horizontal ring plate, and the bottom of the hopper is in close contact with the top surface of the horizontal ring plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Through the setting of the crushing unit, the drive shaft drives the execution module and the bearing ring to rotate synchronously. After the material falls between the bearing ring and the conical screen, the rotation of the bearing ring squeezes the material towards the conical screen, so that part of the blocky material passes through the screen holes on the conical screen to the inside of the conical screen. When the execution module rotates, it cuts the part of the material that passes through the conical screen, thereby realizing the cyclic cutting and crushing of the material. The uppermost crushing unit performs primary crushing of the material. The crushed material enters the middle crushing unit for secondary crushing. Finally, after passing through the lowermost crushing unit for tertiary crushing, the material falls into the receiving hopper and is discharged. This device utilizes the elasticity of the waste rubber itself, cyclically squeezes the material through the bearing ring, and cuts the part that protrudes to the inside of the conical screen, thereby realizing multiple crushing of the blocky material. The size of the part cut off each time is relatively uniform, and the material avoidance during the cutting of the execution module is reduced, thereby improving the crushing effect and uniformity of waste rubber.

[0021] 2. By setting the bearing ring and the inclined pusher, the bearing ring is eccentric relative to the transmission sleeve, which in turn causes the bearing ring and the conical screen to be eccentric as well. This results in a larger gap between the side of the bearing ring away from the transmission sleeve and the conical screen, and a smaller gap between the side of the bearing ring closer to the transmission sleeve and the conical screen. The arc-shaped blade is aligned with the other side of the bearing ring. When the bearing ring rotates, it pushes the material against the conical screen. When the material is at the narrowest point of the middle chamber, the execution module cuts the material. Subsequently, the bearing ring gradually releases its pressure on the material. The inclined pusher is then positioned to further compress the material. The material is scraped and pushed by the conical screen to disengage the material blocks stuck in the screen holes, facilitating subsequent adjustment and re-compression of the material blocks. This allows other parts of the material blocks to pass through the screen holes. Through the eccentric setting and revolution of the bearing rings, the material in the intermediate chamber is circulated, compressed, and relaxed. Combined with the continuous agitation of the material in the intermediate chamber by the bearing rings, the posture of the material is constantly adjusted, rather than being continuously compressed, thus facilitating partial passage of the material through the conical screen, thereby facilitating the compression, cutting, and crushing of the material.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8In this embodiment of the invention, a waste rubber pyrolysis and crushing processing device includes a base 100, a feeding hopper 200, a crushing unit 300, and a receiving hopper 400. Positioning pins 130 are fixedly installed on both sides of the base 100. A drive shaft 120 is rotatably connected to the top of the base 100. A drive motor 110 is installed on the top surface of the base 100, and the output end of the drive motor 110 is rotatably connected to the bottom end of the drive shaft 120. There are three crushing units 300, which are stacked sequentially between two positioning pins 130. Each crushing unit 300 includes a bearing ring 310 and an outer... The housing 320, conical screen 330, and execution module 340 are slidably connected to the drive shaft 120. The housing 320 is slidably connected to the two positioning pins 130. The feeding hopper 200 is located above the three crushing units 300 and is used to guide materials into the crushing units 300. The receiving hopper 400 is located below the three crushing units 300 and is installed between the two positioning pins 130. One side of the receiving hopper 400 is fixedly connected to the discharge port 410 and is used to receive and discharge the processed materials.

[0034] Specifically, the drive motor 110 drives the transmission shaft 120 to rotate, and the transmission shaft 120 drives the execution module 340 and the bearing ring 310 to rotate synchronously. Material is added from the hopper 200 to the top of the crushing unit 300. The material falls between the bearing ring 310 and the conical screen 330. Through the rotation of the bearing ring 310, the material is squeezed towards the conical screen 330, causing some of the lumpy material to pass through the screen holes to the inside of the conical screen 330. When the execution module 340 rotates, it cuts the portion of the material that has passed through the conical screen 330, thereby achieving cyclic cutting and crushing of the material. The uppermost crushing unit... The material is first crushed in unit 300, and then crushed in the middle crushing unit 300 for secondary crushing. Finally, it is crushed a third time in the bottom crushing unit 300 before falling into the receiving hopper 400 and being discharged. This device utilizes the elasticity of the waste rubber itself, and the material is circulated and squeezed by the ring 310. The part protruding into the inner side of the conical screen 330 is cut, thereby realizing multiple crushing of block materials. The size of the cut parts of the material is relatively uniform each time, and the material avoidance during the cutting of the execution module 340 is reduced, thereby improving the crushing effect and uniformity of waste rubber.

[0035] Example 1

[0036] like Figures 3-9As shown, in this embodiment, the middle position of the drive shaft 120 is a rib section, and a step is provided between the rib section and the bottom end of the drive shaft 120. A threaded groove is provided on the outer side wall of the top end of the drive shaft 120, and a nut is screwed onto the top end of the drive shaft 120. The outer side wall of the conical screen 330 is frustoconical, and the top end of the conical screen 330 converges towards the center. A vent hole is provided at the top end of the conical screen 330 to prevent interference with the drive shaft 120. Three ring-shaped frames 331 are equidistantly fixed to the inner wall of the conical screen 330. The frame 331 supports the conical screen 330, improving its strength and reducing deformation caused by the ring 310 pressing the material. Multiple positioning blocks 332 are equidistantly fixed to the bottom surface of the lowest annular frame 331. Multiple positioning holes 321 are equidistantly formed on the inner bottom surface of the outer casing 320, corresponding to the positioning blocks 332. The positioning blocks 332 and positioning holes 321 facilitate the snap-fitting of the conical screen 330 onto the outer casing 320, ensuring proper contact between the conical screen 330 and the outer casing 320. The connection between the two rings 20 is detachable, which avoids the material from rubbing against the conical screen 330 and facilitates the rotation of the bearing ring 310 relative to the conical screen 330. The execution module 340 includes a transmission sleeve 2 341, which is used to slide and engage with the rib section of the transmission shaft 120. A mounting bracket 342 is fixedly connected to the outer wall of the transmission sleeve 2 341. An arc-shaped blade 343 is fixedly connected to one end of the mounting bracket 342. One end of the arc-shaped blade 343 is provided with a cutting edge. A guide plate 344 is fixedly connected to the side wall of one end of the arc-shaped blade 343. The transmission sleeve 341 is located in the middle of the bearing ring 310. 12. The transmission sleeve 312 is slidably sleeved with the rib section of the transmission shaft 120. The inclination of the outer wall of the bottom end of the bearing ring 310 is the same as the inclination of the conical screen 330. The outer diameter of the bottom end of the bearing ring 310 is larger than the outer diameter of the bottom end of the conical screen 330. An eccentric frame 313 is fixedly connected between the transmission sleeve 312 and the bearing ring 310. The transmission sleeve 312 and the bearing ring 310 are in an eccentric state. An intermediate chamber 350 is formed between the bearing ring 310 and the conical screen 330. An inclined pusher 311 is fixedly connected to the inner wall of the bearing ring 310 on the side opposite to the transmission sleeve 312.

[0037] In this embodiment, when the drive shaft 120 rotates, it drives the second drive sleeve 341 and the first drive sleeve 312 to rotate. The second drive sleeve 341 drives the two arc-shaped blades 343 to revolve, and the first drive sleeve 312 drives the bearing ring 310 to rotate. Because the bearing ring 310 is eccentric relative to the first drive sleeve 312, the bearing ring 310 and the conical screen 330 are also eccentric, resulting in a larger gap between the side of the bearing ring 310 away from the first drive sleeve 312 and the conical screen 330. The gap between the other side of the transmission sleeve 312 and the conical screen 330 is small. The arc-shaped blade 343 is aligned with the other side of the bearing ring 310. When the bearing ring 310 rotates, it drives the material to be squeezed into the conical screen 330. When the material is at the narrowest point of the intermediate chamber 350, the execution module 340 cuts the material. Then, the bearing ring 310 gradually relaxes its pressure on the material. Through the setting of the inclined pusher 311, the relaxed material is scraped and pushed, removing the material stuck on the screen holes of the conical screen 330. The block detaches from the conical screen 330, facilitating subsequent posture adjustment and re-compression of the material block. This allows other parts of the material block to pass through the screen holes of the conical screen 330. Through the eccentric setting of the bearing ring 310 and its revolution, the material in the intermediate chamber 350 undergoes cyclic compression and relaxation. Combined with the continuous agitation of the material in the intermediate chamber 350 by the bearing ring 310, the material is cut by the arc-shaped blade 343. The guide plate 344 guides the cut material. This facilitates guiding the cut material to fall into the coverage area of ​​the top of the bearing ring 310 at the lower position, thereby facilitating the introduction of the material into the lower intermediate chamber 350. The detachable connection between the conical screen 330 and the outer casing 320 allows for easy replacement of the conical screen 330 with different screen hole sizes as needed. When replacing, loosen and remove the nut at the top of the drive shaft 120 to remove the bearing ring 310 and the outer casing 320 above the target conical screen 330, and then replace the target conical screen 330.

[0038] Example 2

[0039] Based on Embodiment 1, in order to facilitate the material passing through multiple crushing units 300 from top to bottom in Embodiment 1 and to prevent the material from falling between the bearing ring 310 and the outer shell 320, thereby enhancing the crushing and processing effect of the material.

[0040] like Figures 3-7As shown, in this embodiment, the size of the screen holes on the multiple conical screens 330 decreases from top to bottom. The two adjacent conical screens 330 are staggered by 180 degrees. Fixed sleeves 322 are fixedly connected to both sides of the outer wall of the outer casing 320. The fixed sleeves 322 are used to slide and engage with the positioning pin 130. The sum of the heights of the transmission sleeve 2 341 and the transmission sleeve 1 312 is the same as the height of the fixed sleeve 322. The top of the uppermost ring 310 in the three crushing units 300 is fixedly connected to a horizontal ring plate 314. The bottom of the hopper 200 is in close contact with the top surface of the horizontal ring plate 314.

[0041] In specific implementation, by staggering two adjacent conical screens 330 by 180 degrees, the cutting edge of the arc-shaped blade 343 corresponds to one side of the lower ring 310, making it convenient for the lower ring 310 to catch the falling material. The arrangement of multiple conical screens 330 facilitates the sequential crushing of materials from top to bottom, thereby improving the uniformity of material crushing. By setting the height of the fixed sleeve 322, the transmission sleeve 2 341, and the transmission sleeve 1 312, the multiple fixed sleeves 322 squeeze upwards and downwards, while the multiple transmission sleeves 2 341 and the transmission sleeve 1 312 stack and squeeze upwards and downwards, so that the height of the ring 310 is supported by the transmission sleeve 1 312, avoiding tight pressure between the ring 310 and the outer shell 320, thus facilitating the rotation of the ring 310.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
