Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery recycling, in particular to a plastic mud washing device for lead-acid battery recycling. Background Art

[0002] After the lead-acid battery shell is recycled, it needs to be broken into recycled plastics. However, since the recycled plastics are covered with lead, the recycled plastics need to be cleaned. Some recycled plastics have less lead, while other recycled plastics have more lead. When the existing cleaning device stirs and cleans the recycled plastics, all the recycled plastics are stirred together by the stirring mechanism. The stirring mechanism has a large overall volume, has great resistance when rotating, and is easily damaged. When the lead on the recycled plastics with less lead is washed away, there is still residual lead on the recycled plastics with more lead. Therefore, the stirring mechanism of the cleaning device needs to increase the working time, so that all the recycled plastics meet the cleaning standards. As a result, the motor used to drive the stirring mechanism in the existing cleaning device has a large load and high energy consumption. At the same time, the existing cleaning device lacks a cleaning water recycling device and consumes a large amount of water.

[0003] The patent document with application number CN202122866416.X discloses a plastic mud washing device for lead-acid battery recycling, which adds recycled plastic to the mesh cylinder in the first box body, and then uses the first spiral blade and the stirring rod to fully stir the recycled plastic in the mesh cylinder. Then the recycled plastic washed for the first time is transferred to the filter in the second box body, and the recycled plastic entering the second box body is cleaned under the stirring action of the second spiral blade in the second box body. When the recycled plastic is washed for the first time, the first spiral blade and the stirring rod are required to stir all the plastics in all the mesh cylinders. Therefore, the load of the first motor driving the first spiral blade and the stirring rod is large, the energy consumption is high, and the stirring mechanism composed of the first spiral blade and the stirring rod has large resistance when rotating and is easy to be damaged. When the recycled plastic is washed in the second box body, the second spiral blade is used to stir the recycled plastic above the filter. The recycled plastic is easy to accumulate above the filter. The residual lead in the recycled plastic is not convenient to be washed away. If the cleaning standard needs to be met, more water is required. At the same time, the patent cannot recycle the washing water.

[0004] The patent document with application number CN202222827874.7 discloses a plastic mud washing device for lead-acid battery recycling. When working, the recycled plastic is added into the box through the material port, and the cleaning liquid is added into the box, and the liquid level of the cleaning liquid is located below the turntable. The recycled plastic with more lead adhesion sinks into the cleaning liquid, and the recycled plastic with less lead adhesion floats on the liquid surface of the cleaning liquid. Start the motor, the motor drives the turntable, the support rod, the first stirring rod and the second stirring rod to move, and the recycled plastic floating on the cleaning liquid is stirred and cleaned by the first stirring rod and the second stirring rod.

[0005] Start the aeration pump, which aerates the lower end of the box through the aeration pipe. The bubbles generated during the aeration process cause the recycled plastic to move in the cleaning liquid in the lower end of the box. By setting multiple inner rods, the bubbles drive the recycled plastic to move, which can cause the recycled plastic to collide with the inner rod, which can accelerate the shedding of the lead on the recycled plastic, thereby improving the cleaning efficiency. At the same time, under the dual effects of upper stirring and lower aeration, the cleaning efficiency of the recycled plastic can be further improved. When the lead adhered to the recycled plastic that sinks into the cleaning liquid is separated from the recycled plastic, the recycled plastic floats to the liquid surface of the cleaning liquid under the action of buoyancy. The cleaning liquid is left to stand for a set time to allow the lead in the cleaning liquid to precipitate, and then the valve on the discharge pipe is opened. The upper cleaning liquid will carry the recycled plastic floating on the cleaning liquid and be discharged from the discharge pipe and enter the vibrating screen. The recycled plastic remains in the vibrating screen, and the cleaning liquid enters the sump. Then the water pump is started to spray water from the spray pipe, and the vibrating screen is started to disperse the recycled plastic in the vibrating screen, thereby improving the flushing efficiency of the recycled plastic and reducing the water consumption. The liquid in the sump can pass through the filter press to remove the lead inside, and the liquid with lead removed can be added to the box for secondary use. The technical solution of this patent has the following technical problems during use: 1. The plastic in the lower end of the box is cleaned by aeration, and the cleaning efficiency is low. During the aeration process of the cleaning liquid in the box, the cleaning liquid is prone to produce more foam, and the foam is easily discharged to the outside of the box through the material port during the aeration process. 2. When flushing the plastic on the vibrating screen, it is necessary to take water again. Utility Model Content

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0050] Example 1: Reference Figure 1-Figure 2 As shown, a plastic mud washing device for lead-acid battery recycling includes a box body 1, and an inlet 8 is opened at the upper end of the box body 1. Plastic can be put into the box body 1 through the inlet 8.

[0051] A vertical spline shaft 3 is rotatably connected in the housing 1, a motor 2 is fixed at the upper end of the housing 1, and the output shaft of the motor 2 is fixedly connected to the upper end of the spline shaft 3. A sliding plate 4 is slidably arranged on the spline shaft 3 in the housing 1, and a plurality of support rods 5 are evenly fixed on the outer circumference of the sliding plate 4, the support rods 5 are perpendicular to the spline shaft 3, and a plurality of stirring rods 6 are evenly fixed at the lower end of the support rods 5 along the axial direction thereof, and the length of the stirring rods 6 decreases in sequence from the end of the support rods 5 away from the slide plate to the end of the support rods 5 close to the slide plate.

[0052] A buoyancy box 7 is fixed at the lower end of the sliding plate 4. A guide cone 10 is fixed in the lower end of the box body 1. A retaining ring 9 is fixed on the spline shaft 3 above the guide cone 10. An outlet pipe 11 is fixed on the bottom plate of the box body 1 outside the guide cone 10, and a discharge pipe 12 is fixedly connected to one side of the box body 1.

[0053] When cleaning the plastic in the box 1, a cleaning liquid is added into the box 1. When the cleaning liquid is added into the box 1, as the level of the cleaning liquid in the box 1 continues to rise, the buoyancy of the buoy 7 causes the buoy 7, the sliding plate 4, the support rod 5 and the stirring rod 6 to move upward along the axial direction of the spline shaft 3.

[0054] After the cleaning liquid is stopped from being added into the box 1, some plastics float on the upper end of the cleaning liquid, and plastics with more lead mud sink into the lower end of the box 1. The motor 2 is started, and the motor 2 drives the spline shaft 3, the sliding plate 4, the floating box 7, the support rod 5 and the stirring rod 6 to rotate. When the stirring rod 6 rotates, the plastics floating on the upper end of the cleaning liquid can be stirred.

[0055] After the plastic floating on the upper end of the cleaning liquid is stirred and cleaned, the discharge pipe 12 is opened to discharge part of the cleaning liquid and the plastic floating on the upper end of the cleaning liquid to the outside of the box body 1. During the cleaning liquid discharge process, the sliding plate 4, the floating box 7, the support rod 5 and the stirring rod 6 move downward along the axial direction of the spline shaft 3.

[0056] After the sliding plate 4, the floating box 7, the support rod 5 and the stirring rod 6 move downward, the motor 2 is started again. The motor 2 can drive the sliding plate 4, the floating box 7, the support rod 5 and the stirring rod 6 to rotate through the spline shaft 3 and stir the plastic at the lower end of the box body 1.

[0057] By setting the retaining ring 9, when the buoyancy box 7 contacts the retaining ring 9, the sliding plate 4, the buoyancy box 7, the support rod 5 and the stirring rod 6 cannot continue to move downward. At this time, there is a gap between the stirring rod 6 and the guide cone 10 to prevent the guide cone 10 from causing rotational friction after contacting the stirring rod 6.

[0058] The length of the stirring rod 6 decreases gradually from the end of the support rod 5 away from the slide to the end of the support rod 5 close to the slide. When stirring the plastic in the lower end of the box body 1, the lower end of the stirring rod 6 can be close to the guide cone 10, which can ensure the stirring efficiency of the plastic in the lower end of the box body 1.

[0061] A filter screen 21 is fixed in the filter box 20. An opening is provided on the side wall of the filter box 20 above the filter screen 21, and a sealing plate 22 is detachably fixed and sealedly connected to the filter box 20, and the sealing plate 22 blocks the opening.

[0062] After the outlet pipe 11 is opened, the lead mud and plastic in the lower end of the box body 1 enter the filter box 20 through the outlet pipe 11 and the seventh pipe 26. The plastic entering the filter box 20 is intercepted by the filter screen 21, and the cleaning liquid and lead mud are located in the lower end of the filter box 20.

[0063] The filter box 20 is connected to the filter press 17. Specifically, the lower end of the filter box 20 is connected to the inlet end of the filter press 17 through the third pipe 19. When the third pipe 19 is opened, the lead mud and the cleaning liquid at the lower end of the filter box 20 can enter the filter press 17, the filter press 17 filters the lead mud, and the cleaning liquid is discharged from the liquid outlet of the filter press 17.

[0064] The filter press 17 is connected to the storage tank 16. Specifically, the liquid outlet of the filter press 17 is connected to the storage tank 16 through the sixth pipeline 25. After the cleaning liquid is discharged from the liquid outlet of the filter press 17, it enters the storage tank 16 through the sixth pipeline 25 for storage.

The liquid outlet of the vibrating screen 13 is connected to the inlet end of the filter press 17 through a second pipe 18, and the storage tank 16 is connected to the flushing pipe 14 through a first pipe 15, and a water pump is installed on the first pipe 15.

[0067] The cleaning liquid and plastic discharged from the discharge pipe 12 enter the vibrating screen 13, the vibrating screen 13 and the first step pipeline water pump are started, the cleaning liquid in the storage tank 16 can be pumped into the flushing pipe 14, and the cleaning liquid discharged from the flushing pipe 14 can perform secondary spray flushing on the plastic on the vibrating screen 13. The cleaning liquid discharged from the vibrating screen 13 can enter the filter press 17 again for filtration.

[0068] The storage tank 16 is connected to the filter box 20. Specifically, the storage tank 16 is connected to the upper end of the filter box 20 through the fourth pipe 23. The water pump on the fourth pipe 23 is started, and the cleaning liquid in the storage tank 16 can be transported to the filter box 20. After the cleaning liquid in the storage tank 16 enters the filter box 20, it can wash the plastic above the filter screen 21. The cleaning liquid for washing the plastic flows back to the filter press 17 through the third pipe 19 for pressure filtering.

[0069] In this embodiment, the cleaning liquid in the storage tank 16 can be used to wash the plastic in the vibrating screen 13 and the plastic on the upper end of the filter screen 21 of the filter box 20. At the same time, the cleaning liquid in the storage tank 16 can also be returned to the box body 1 for use, and the recycling rate of the cleaning liquid is high.
