Description

Technical Field

[0001] This utility model relates to the field of polyamide production technology, specifically to a polyamide production equipment. Background Technology

[0002] When polyamide materials are granulated, the particle size range is relatively wide, resulting in some residue that needs to be screened. According to a polyamide production equipment with continuous feeding capability (application number CN218803373U), a motor and auger shaft are installed in the feeding channel to achieve continuous feeding of polyamide. Simultaneously, a sieve plate is installed in the feeding channel to screen impurities within the polyamide particles. Furthermore, vibrators are installed on both sides of the slag discharge pipe below the feeding channel to vibrate and discharge impurities deposited on the bottom wall of the feeding channel, reducing accumulation and significantly improving polyamide production efficiency. However, some impurities can become stuck inside the sieve holes on the sieve plate, which the equipment cannot clean, causing some sieve holes to become blocked, thus affecting the efficiency of screening raw materials through the sieve plate.

[0010] This utility model provides a polyamide production equipment, which has the following beneficial effects:

[0011] 1. This polyamide production equipment is equipped with a push column, filter holes, and filter plates. The output of a second motor drives a threaded rod to rotate, which in turn drives a drive block to move a drive box downwards along the surface of the first and second support bars. The drive box then moves to the working position. Next, the output of a third motor drives the threaded column to rotate, which in turn drives the push block and one end of the push column. This causes one end of the push column to pass through the filter holes and push out the blockages inside the filter holes. At this point, one end of the push column can be inserted to the very top of the filter holes, making the inner side of the filter plate flat. Then, the output of the first motor drives a screw conveyor shaft to rotate, which discharges the blockages inside the conveying cylinder through the discharge pipe into a waste collection container, thereby ensuring the efficiency of the filter holes in screening the raw materials.

[0022] The drive box 21 has three rows of drive chambers 22. A third motor 24 is fixedly connected to one end of each drive chamber 22. A threaded column 23 is rotatably connected to the other side of each drive chamber 22. The output end of each third motor 24 is fixedly connected to one end of the threaded column 23. A push block 25 is threadedly connected to the outside of each threaded column 23. A push column 26 is fixedly connected to one end of each push block 25. One end of each push column 26 extends to the outside of the drive box 21. The positions of the three rows of push columns 26 correspond to the positions of the three rows of filter holes 9. The push columns 26 push out the blockages inside the filter holes 9.

[0023] Two second support bars 19 are fixedly connected between the two side plates 1. The two second support bars 19 are located below the two ends of the drive box 21, and the two ends of the drive box 21 are supported by the two second support bars 19.

[0024] Two first support bars 18 are fixedly connected to one side of the fixed frame 13. The two first support bars 18 are located below both ends of the drive box 21, and the two first support bars 18 support both ends of the drive box 21.

[0026] Example 2

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a collection tray 20 is placed between two side plates 1 and below the filter plate 8. Two threaded holes 11 are opened inside the conveying cylinder 2 and on the inner walls at both ends of the mounting groove 7. Four screws 10 are threaded inside the filter plate 8. One end of each screw 10 extends into the threaded hole 11 and is threaded into the threaded hole 11. A first motor 3 is fixedly connected to one side of one side plate 1. The output end of the first motor 3 passes through the side plate 1 and extends into the conveying cylinder 2 and is fixedly connected to one end of the spiral conveying shaft 4. A controller is fixedly connected to the back of the fixing frame 13. The electrical components of this device are controlled by the controller.

[0028] In summary, when using this polyamide production equipment, the power is turned on, and the raw material is poured into the conveying cylinder 2 through the feed pipe 5. The output end of the first motor 3 drives the screw conveyor shaft 4 to rotate, so that the screw conveyor shaft 4 drives the raw material inside the conveying cylinder 2 to move inside the conveying cylinder 2. The raw material with smaller particles falls into the collection tray 20 through the filter hole 9. Then, the raw material that meets the particle size is pushed into the discharge pipe 6 through the screw conveyor shaft 4, and then discharged into the collection container placed below the conveying cylinder 2 through the discharge pipe 6.

[0029] When it is necessary to clean the blockage inside the filter hole 9, the output end of the second motor 16 drives the threaded rod 15 to rotate, causing the threaded rod 15 to drive the drive block 17 to move the drive box 21 downwards in the conveying cylinder 2. This causes the drive box 21 to move along the surfaces of the first support bar 18 and the second support bar 19. Then, the drive box 21 moves to the working position. Next, the output end of the third motor 24 drives the threaded column 23 to rotate, causing the threaded column 23 to drive the push block 25 and one end of the push column 26. This causes one end of the push column 26 to pass through the filter hole 9 and push out the blockage inside the filter hole 9. At this time, one end of the push column 26 can be inserted to the very top of the filter hole 9, making the inner side of the filter plate 8 flat. Then, the output end of the first motor 3 drives the screw conveyor shaft 4 to rotate, causing the screw conveyor shaft 4 to push the blockage inside the conveying cylinder 2 through the discharge pipe. 6. The waste is discharged into the waste collection container. Then, the output end of the third motor 24 drives the threaded column 23 to reset and rotate, so that the threaded column 23 drives the push block 25 to move the push column 26 out of the filter hole 9, so that the push block 25 and the push column 26 move to the initial position. Then, the output end of the second motor 16 drives the threaded rod 15 to reset and rotate, so that the threaded rod 15 drives the drive block 17 and the drive box 21 to move through the removal groove 12 to the top of the first support bar 18. When the filter plate 8 needs to be replaced, one end of the screw 10 is unscrewed from the threaded hole 11 to release the limiting fixation of the filter plate 8. Then, the filter plate 8 is taken out from the installation groove 7 and placed into the installation groove 7. Then, one end of the screw 10 is screwed into the threaded hole 11 to fix the position of the filter plate 8, so that the filter plate 8 is installed on the conveying cylinder 2.
