[0007] Preferably, the outer side of the recycling tank is fixedly connected to a discharge port, the bottom of the recycling tank is fixedly connected to a discharge pipe, and a valve is installed on the outer side of the discharge pipe.

[0008] Preferably, the cover structure includes a cover body and multiple hydraulic cylinders. The cover body is disposed on the top of the recycling tank and is rotatably connected to the outer side of the top of the rotating shaft. A feed hopper is installed on the top of the cover body. The multiple hydraulic cylinders are all fixedly connected to the outer side of the recycling tank, and the tops of the multiple hydraulic cylinders are all fixedly connected to the cover body. The arrangement of multiple hydraulic cylinders ensures the smooth lifting and lowering of the cover body, improving the stability of the equipment and the safety of operation.

[0009] Preferably, the filtration structure includes a first filter plate and a second filter plate, both of which are disposed inside the recycling and processing tank. The second filter plate is disposed at the bottom of the first filter plate. A limiting ring is rotatably connected to the center of both the first and second filter plates. A limiting block is slidably connected inside each of the two limiting rings. Both limiting blocks are fixedly connected to the rotating shaft. Multiple magnetic rings are installed at the bottom of the first filter plate, and magnetic strips are installed at the bottom of each magnetic ring.

[0010] Preferably, the filter structure further includes multiple vertical grooves and multiple vertical plates. The multiple vertical grooves are all opened inside the recycling and processing box, and the multiple vertical plates are slidably disposed inside the multiple vertical grooves. The top ends of the multiple vertical plates are fixedly connected to the cover. The first filter plate and the second filter plate are disposed between the multiple vertical plates. The multiple vertical plates are respectively connected to the first filter plate and the second filter plate by internal hex bolts. The arrangement of the multiple vertical plates allows the first filter plate and the second filter plate to be moved out together when the cover is opened, which further facilitates the operator to clean and replace the first filter plate and the second filter plate.

[0011] Preferably, the operating structure includes a hollow circular seat, which is fixedly connected to the top of the rotating shaft. The top of the threaded rod extends into the interior of the hollow circular seat and is rotatably connected to the hollow circular seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a worm gear and a worm wheel meshing together. The worm wheel then drives the threaded rod to rotate inside the square groove. Since the threaded rod is threadedly connected to the two lifting blocks, the two lifting blocks will drive multiple fixed blocks to slide towards the top of multiple L-shaped grooves under the rotation of the threaded rod. As the fixed blocks move, they will release the limit on multiple cross blocks. At this time, the operator can lift the impeller that needs to be replaced upwards, move the cross blocks to the L-shaped groove position, and then pull out the cross blocks. Through this operation, the impeller and the crushing blade can be replaced, which is convenient for operators and greatly improves the practicality of the device.

[0015] 2. This application uses multiple hydraulic cylinders to lift the cover upwards, separating the cover from the recycling tank. Since the cover is connected to the first and second filter plates through multiple vertical plates, when the cover is lifted, the cover will drive the first and second filter plates to move upwards together through the multiple vertical plates, thereby moving the first filter plate, the second filter plate, and the rotating shaft out of the recycling tank, which facilitates the disassembly of components such as the stirring impeller.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a recycling and processing device for propylene raw materials, including a recycling and processing tank 1. A discharge port 100 is fixedly connected to the outside of the recycling and processing tank 1, and a discharge pipe 101 is fixedly connected to the bottom of the recycling and processing tank 1. A valve is installed on the outside of the discharge pipe 101. A rotating shaft 11 is provided inside the recycling and processing tank 1. A cover plate structure is provided on the outer side of the top of the rotating shaft 11. A filter structure is provided on the outer side of the rotating shaft 11. A square groove 110 is formed inside the rotating shaft 111. A threaded rod 16 is provided inside the square groove 110. The bottom end of the threaded rod 16 is rotatably connected to the rotating shaft 11. An operating structure is provided at the top of the threaded rod 16. Two sets of stirring structures are provided on the outer side of the threaded rod 16. The stirring structure includes two L-shaped grooves 20. Both L-shaped grooves 20 are formed inside the square groove 110. A fixed block 21 is slidably arranged inside each of the two L-shaped grooves 20. A lifting block 19 is fixedly connected between the two fixed blocks 21. The lifting block 19 is threadedly connected to the outside of the threaded rod 16. A cross groove 190 is formed at the bottom of each of the two L-shaped grooves 20. A cross block 121 is slidably arranged inside each of the two cross grooves 190. The two cross blocks 121 are in contact with the two fixed blocks 21 respectively. A stirring impeller 12 is fixedly connected to one side of each of the two cross blocks 121. Both stirring impellers 12 are arranged above the first filter plate 4. Both sides of the two stirring impellers 12 are equipped with crushing blades 120. The other two stirring impellers 12 are arranged above the second filter plate 5.

[0025] The operating structure includes a hollow round seat 13, which is fixedly connected to the top of the rotating shaft 11. The top of the threaded rod 16 extends into the interior of the hollow round seat 13 and is rotatably connected to the hollow round seat 13. A worm gear 17 is fixedly connected to the outer side of the top of the threaded rod 16, and a worm 18 is meshed with the outer side of the worm gear 17. Both ends of the worm 18 pass through the inner side of the hollow round seat 13 and are rotatably connected to the hollow round seat 13. A throttle is installed at one end of the worm 18. A motor is installed at the top of the hollow round seat 13 and is fixedly connected to the top of the cover 2. The output end of the motor is fixedly connected to the hollow round seat 13.

[0026] Specifically, the operator first turns the handle, at which point the worm 18 meshes with the worm wheel 17, and the worm wheel 17 drives the threaded rod 16 to rotate inside the square groove 110. Since the threaded rod 16 is threadedly connected to the two lifting blocks 19, the two lifting blocks 19 will drive multiple fixed blocks 21 to slide towards the top of multiple L-shaped grooves 20 under the rotation of the threaded rod 16. As the fixed blocks 21 move, they will release the limit on multiple cross blocks 121. At this time, the operator can lift the impeller 12 that needs to be replaced, move the cross block 121 to the position of the L-shaped groove 20, and then pull out the cross block 121. Through this operation, the impeller 12 and the crusher blade 120 can be replaced, which is convenient for operators and greatly improves the practicality of the device.

[0027] Example: Figure 1 - Figure 3 As shown, the cover structure includes a cover body 2 and multiple hydraulic cylinders 3. The cover body 2 is located on the top of the recycling tank 1 and is rotatably connected to the outer side of the top of the rotating shaft 11. A feed hopper is installed on the top of the cover body 2. The multiple hydraulic cylinders 3 are all fixedly connected to the outer side of the recycling tank 1, and the tops of the multiple hydraulic cylinders 3 are all fixedly connected to the cover body 2.

[0028] The filter structure includes a first filter plate 4 and a second filter plate 5. Both the first filter plate 4 and the second filter plate 5 are located inside the recycling tank 1. The second filter plate 5 is located at the bottom of the first filter plate 4. A limiting ring 15 is rotatably connected to the center of both the first filter plate 4 and the second filter plate 5. A limiting block 14 is slidably connected inside both limiting rings 15. Both limiting blocks 14 are fixedly connected to the rotating shaft 11. Multiple magnetic rings 9 are installed at the bottom of the first filter plate 4. Magnetic strips 10 are installed at the bottom of the magnetic rings 9. The filter structure also includes multiple vertical grooves 6 and multiple vertical plates 7. The multiple vertical grooves 6 are all opened inside the recycling tank 1. The multiple vertical plates 7 are slidably arranged inside the multiple vertical grooves 6. The tops of the multiple vertical plates 7 are fixedly connected to the cover 2. The first filter plate 4 and the second filter plate 5 are both arranged between the multiple vertical plates 7. The multiple vertical plates 7 are connected to the first filter plate 4 and the second filter plate 5 respectively by internal hex bolts 8.

[0029] Specifically, the operator can activate multiple hydraulic cylinders 3, which will lift the cover 2 upwards, separating it from the recycling tank 1. Since the cover 2 is connected to the first filter plate 4 and the second filter plate 5 through multiple vertical plates 7, when the cover 2 is lifted, it will move the first filter plate 4 and the second filter plate 5 upwards together through the multiple vertical plates 7, thereby moving the first filter plate 4, the second filter plate 5 and the rotating shaft 11 out of the recycling tank 1, which facilitates the disassembly of components such as the stirring impeller 12. In addition, if it is necessary to disassemble the first filter plate 4 and the second filter plate 5 themselves, the operator can remove the multiple hexagonal bolts 8 set on the multiple vertical plates 7, which makes it easy to disassemble and replace the first filter plate 4 and the second filter plate 5.
