[0027] As Figures 1 - 4As shown in the figure, a limit component is arranged outside the recycling bin 1. The limit component consists of a turntable 6, a rotating rod 7, a first bevel gear 8, a second bevel gear 9, a threaded rod 10, a lifting plate 11, a baffle plate 12, a T-shaped slider 20 and a support plate 21. A turntable 6 is arranged outside the recycling bin 1. A rotating rod 7 is fixedly arranged on one side of the turntable 6 close to the recycling bin 1. A first bevel gear 8 is fixedly arranged on the other side of the rotating rod 7.

A T-shaped chute adapted to the T-shaped slider 20 is arranged on the side surface of the recycling bin 1. The T-shaped slider 20 is slidably connected to the recycling bin 1 through the T-shaped chute. A support plate 21 is fixedly arranged on the side surface of the recycling bin 1. The bottom surface of the second bevel gear 9 is rotationally connected to the support plate 21. The threaded rod 10 penetrates through the support plate 21 and is rotationally connected to the support plate 21. The support plate 21 supports the second bevel gear 9. Rotating the turntable 6 to drive the baffle plate 12 to move upward can facilitate removing the mounting frame 3 to disassemble the filter net 17. When the baffle plate 12 moves upward and closely adheres to the mounting frame 3, the cover plate 4 and the partition plate 5, the positions of the mounting frame 3, the cover plate 4 and the partition plate 5 can be limited, thereby facilitating limiting the position of the filter net 17.

[0028] Specifically, when it is necessary to disassemble the filter net 17, rotate the turntable 6 to drive the rotating rod 7 and the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the lifting plate 11 to move upward, thereby driving the baffle plate 12 to move upward. When the baffle plate 12 disengages from the mounting frame 3, the cover plate 4 and the partition plate 5, pulling the first fixing rod can remove the mounting frame 3, thereby facilitating the disassembly of the filter net 17. After completing the installation of the filter net 17, install the mounting frame 3 back to its original position. Rotate the turntable 6 in the reverse direction to drive the baffle plate 12 to move downward until the baffle plate 12 closely adheres to the mounting frame 3, the cover plate 4 and the partition plate 5, and the positions of the mounting frame 3, the cover plate 4 and the partition plate 5 can be re-limited, thereby facilitating limiting the position of the filter net 17. When it is necessary for the filter net 17 to filter the liquid and sediment generated by the reaction of the waste alkali liquid and the precipitant, rotate the turntable 6 to drive the baffle plate 12 to move upward. When the baffle plate 12 just disengages from the partition plate 5, pull the second fixing rod to drive the partition plate 5 to move outward until the slot 19 is aligned with the baffle plate 12. Rotate the turntable 6 in the reverse direction to drive the baffle plate 12 to move downward and engage it inside the slot 19, and the position of the partition plate 5 can be limited. At this time, the partition plate 5 is completely away from the filter net 17, thereby facilitating the filter net 17 to filter the liquid and sediment generated by the reaction of the waste alkali liquid and the precipitant.

[0029] Specific working principle:

[0030] When the device is in use, waste alkali liquor and precipitant are added into the inside of the recovery barrel 1 through the feeding port. The partition plate 5 is arranged on the bottom surface of the filter net 17 and covers the filter net 17. The partition plate 5 can prevent the liquid from passing through the filter net 17, thus facilitating the full mixing and reaction of the waste alkali liquor and the precipitant. The running motor 2 drives the rotating shaft 13 and the stirring rod 14 to rotate, thereby accelerating the reaction between the waste alkali liquor and the precipitant. The waste alkali liquor and the precipitant react to produce liquid and sediment.

[0031] After the waste alkali liquor finishes reacting with the precipitant, rotate the turntable 6 to drive the rotating rod 7 and the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the lifting plate 11 to move upward, thereby driving the baffle plate 12 to move upward. When the baffle plate 12 just disengages from the partition plate 5, pull the second fixing rod to drive the partition plate 5 to move outward until the slot 19 is aligned with the baffle plate 12. Reverse-rotate the turntable 6 to drive the baffle plate 12 to move downward and engage it into the inside of the slot 19, which can limit the position of the partition plate 5. At this time, the partition plate 5 is completely away from the filter net 17, thus facilitating the filter net 17 to filter the liquid and sediment produced by the reaction of the waste alkali liquor and the precipitant. The liquid passes through the filter net 17 and enters the recovery barrel 1 below the filter net 17, and the sediment remains on the top surface of the filter net 17.

[0032] After the filter net 17 finishes filtering the liquid and sediment, opening the valve allows the liquid to flow out through the liquid outlet pipe 15. Rotate the turntable 6 to drive the baffle plate 12 to move upward. When the baffle plate 12 disengages from the mounting frame 3, the cover plate 4 and the partition plate 5, pull the first fixing rod to remove the mounting frame 3, open the cover plate 4 to take out the support sleeve 16 and the filter net 17, thus facilitating the recovery of the sediment on the top surface of the filter net 17, cleaning the surface of the filter net 17, repairing or replacing the filter net 17. After installing the filter net 17, install the mounting frame 3 in place. Reverse-rotate the turntable 6 to drive the baffle plate 12 to move downward until the baffle plate 12 closely adheres to the mounting frame 3, the cover plate 4 and the partition plate 5, which can re-limit the positions of the mounting frame 3, the cover plate 4 and the partition plate 5, thus facilitating the limitation of the position of the filter net 17.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and do not limit the present utility model.
