Description

Technical Field

[0001] The utility model relates to the technical field of specific gravity separation equipment, in particular to a specific gravity separation equipment for separating and recycling copper and aluminum from waste batteries. Background Technique

[0002] The specific gravity separation equipment is a kind of equipment that separates materials by using the specific gravity difference of materials. It mainly works based on the principle that the sedimentation velocity of materials in the gravitational field is proportional to the density of materials. The specific gravity separation equipment is usually used to separate substances with different densities and is widely used in industries such as minerals, food, and pharmaceuticals.

[0003] For common specific gravity separation equipment, first, a magnetic separator is used to separate metals and impurities, and then different-density and -weight metals are further separated through a flotation liquid to achieve the effect of separation and recycling. However, it lacks the function of circulating filtration and cannot filter the flotation liquid during the process of recycling and remove impurities in the liquid. As a result, the flotation liquid becomes too turbid after multiple cycles of use, and it is necessary to re-inject the flotation liquid, which reduces the recycling time of the flotation liquid and increases the use cost.

[0004] Therefore, aiming at the problem that the above-mentioned specific gravity separation equipment lacks the function of circulating filtration and cannot filter the flotation liquid during the process of recycling and remove impurities in the liquid, a specific gravity separation equipment for separating and recycling copper and aluminum from waste batteries can be designed. The flotation liquid in the filter box can be filtered through a filter plate to separate impurities from the flotation liquid. Moreover, the second motor can drive the first telescopic rod and the scraper to move synchronously to the right. The movement of the scraper will push the impurities remaining in front of the filter plate towards the through groove, so that the impurities are discharged through the through groove, achieving the purpose of filtering and removing impurities, thereby not only increasing the recycling time of the flotation liquid but also reducing the use cost. Content of the Utility Model

[0005] In order to overcome the problem that the common shoe processing gluing device lacks the function of circulating filtration and cannot filter the flotation liquid during the process of recycling and remove impurities in the liquid, resulting in the flotation liquid becoming too turbid after multiple cycles of use and needing to re-inject the flotation liquid, which reduces the recycling time of the flotation liquid and increases the use cost.

[0006] The technical solution of the present utility model is as follows: A specific gravity separation device for separating and recycling copper and aluminum from waste batteries, which includes a workbench, and also includes a circulating filtration assembly. The circulating filtration assembly includes a filtration tank, a filter plate, a first telescopic rod, a scraper, a second motor, a second telescopic rod, a third motor, a sealing block, and a rubber frame. A separation tank is arranged on the top of the workbench, and a filtration tank is arranged at the bottom of the workbench. The bottom of the separation tank is connected with a first water outlet pipe, and the bottom of the first water outlet pipe passes through the workbench and is communicated with the top of the filtration tank. A filter plate is arranged inside the filtration tank. A first telescopic rod is arranged on the left side inside the filtration tank corresponding to the front side of the filter plate. The right end of the first telescopic rod is connected with a scraper. A second motor is installed at the position corresponding to the first telescopic rod on the left side of the filtration tank, and the output end of the second motor is connected to the left end of the first telescopic rod. A second telescopic rod is arranged on the right side inside the filtration tank, and a third motor is installed at the position corresponding to the second telescopic rod on the top of the filtration tank. The output end of the third motor is connected to the upper end of the second telescopic rod. The lower end of the second telescopic rod is connected with a sealing block, and a rubber frame is installed around the sealing block.

[0007] Preferably, the filter plate can filter the flotation liquid in the filtration tank, so that the impurities in the flotation liquid remain on the front side of the filter plate, while the filtered flotation liquid will flow to the rear side of the filter plate to achieve the purpose of filtering the flotation liquid. And when the flotation liquid in the filtration tank is pumped into the separation tank, the second motor can be started to drive the first telescopic rod to move to the right. The movement of the first telescopic rod will drive the scraper to move synchronously. The movement of the scraper will push the impurities remaining on the front side of the filter plate towards the through groove, so that the impurities are discharged through the through groove. And when the scraper moves to the right, the third motor will be started simultaneously. The start of the third motor will drive the second telescopic rod to move upward, thereby driving the sealing block to move synchronously, so that the sealing block releases the sealing effect on the through groove.

Through the feed inlet, the copper-aluminum powder mixture and the flotation liquid can be conveyed into the sorting box. By starting the first motor, the rotating shaft can be driven to rotate. The rotation of the rotating shaft will cause the stirring rods on its side wall to rotate synchronously, so as to fully mix the copper-aluminum powder mixture and the flotation liquid. After the mixing is completed, the stirring device can be turned off, so that the heavier copper powder sinks to the bottom, while the lighter aluminum powder floats up to achieve the effect of specific gravity separation.

[0013] Preferably, a sealing cover is installed on the top of the collection box. A second screening plate is arranged inside the collection box. L-shaped inserts are connected to the left and right sides of the second screening plate. Slots corresponding to the L-shaped inserts are opened on the left and right sides of the top of the collection box. The L-shaped inserts are connected to the collection box through the slots. A support seat is arranged at the bottom of the collection box, and a second water pipe is connected to the center of the bottom of the collection box. The other end of the second water pipe passes through the support seat and communicates with the top of the filtration box. The aluminum powder and the flotation liquid can be separated by the second screening plate in the collection box, so that the aluminum powder remains on the top of the second screening plate, and the flotation liquid will enter the filtration box through the second water pipe for convenient circulating filtration operation.

[0014] Advantages of the present utility model:

The movement of the scraper will push the impurities remaining on the front side of the filter plate towards the through groove, so as to discharge the impurities through the through groove. And when the scraper moves to the right, the third motor will be started simultaneously. The start of the third motor will drive the second telescopic rod to move upward, thus driving the sealing block to move synchronously, so that the sealing block releases the sealing effect on the through groove. After the scraper finishes cleaning, the second motor will drive the scraper to move to the left, and at the same time the third motor will also drive the sealing block and the rubber frame to move downward, so that the rubber frame outside the sealing block seals the through groove to achieve the purpose of circulating filtration and cleaning impurities.
