[0002] At present, during the recycling and dismantling process of scrap aluminum products, non-metallic substances and metallic non-aluminum substances will be mixed into the scrap aluminum products. The non-metallic and metallic non-aluminum impurities are very harmful to the smelting of scrap aluminum. Among them, the metallic non-aluminum impurities are mainly iron impurities. When there is too much iron, brittle metal crystals will be formed in the aluminum, thereby reducing its mechanical properties and weakening its corrosion resistance.

[0003] For the recycling of waste cans, it is very necessary to sort out the non-metallic and metallic non-aluminum impurities contained in the waste cans. The metallic non-aluminum impurities in the waste cans are usually separated by magnetic separation, while the non-metallic impurities in the waste cans are difficult to remove. Since the weight of waste cans is relatively light, in order to facilitate transportation and storage, the recycled waste cans are usually pressed into cakes or blocks, making the non-metallic impurities in the waste cans more difficult to separate. Summary of the invention

In this embodiment, the two ends of the bottom of the washing tank 302 are arranged obliquely to form an inverted umbrella shape. The lower ends of the light material mesh belt machine 303 and the heavy material mesh belt machine 304 are immersed in the inside of the washing tank 302. The light material mesh belt machine 303 can transport non-metallic impurities to the outside of the washing tank 302, and the heavy material mesh belt machine 304 can transport the washed waste cans to the outside of the washing tank 302.

[0023] The discharge end of the heavy material mesh belt machine 304 is located above the feed port of the spin-drying centrifuge 4, and a mesh belt conveyor 5 is provided between the spin-drying centrifuge 4 and the vibrating fluidized bed 6, and the feed end of the mesh belt conveyor 5 is located below the discharge port of the spin-drying centrifuge 4, and the discharge end of the mesh belt conveyor 5 is located above the feed port of the vibrating fluidized bed 6. In this embodiment, the heavy material mesh belt machine 304 conveys the washed waste cans to the spin-drying centrifuge 4, and the spin-drying centrifuge 4 dehydrates and spin-dries the washed waste cans, and the dried waste cans are discharged from the discharge port of the spin-drying centrifuge 4 and fall onto the mesh belt conveyor 5, and then the waste cans fall from the discharge end of the mesh belt conveyor 5 into the vibrating fluidized bed 6, and the vibrating fluidized bed 6 dries the waste cans through the action of steam.

[0024] A bracket is provided at the bottom of the vibrating feeder 2, and the vibrating feeder 2 is arranged above the water washing machine 3 through the bracket. In this embodiment, the bracket supports the vibrating feeder 2 so that the vibrating feeder 2 is located above the water washing machine 3.

[0025] The water washing machine 3 further comprises a frame 301, a slag removal screw and an internal circulation pump 305. The water washing tank 302 is fixedly arranged on the frame 301. The width of the water washing tank 302 gradually decreases from top to bottom. In this embodiment, the frame 301 plays a role of fixed support for the water washing tank 302.

[0026] The deslagging screw machine is arranged at the bottom of the water washing tank 302, and the internal circulation pump 305 is arranged on one side of the frame 301. The inlet end and the outlet end of the internal circulation pump 305 are respectively connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are connected with the water washing tank 302. In this embodiment, one end of the deslagging screw machine is connected with a sewage tank, and a valve is installed at one end of the deslagging screw machine. The deslagging screw machine can discharge the slag slurry precipitated at the bottom of the water washing tank 302 into the sewage tank, wherein the deslagging screw machine includes a screw shaft and a motor, the screw shaft is located inside the water washing tank 302, and the motor is located outside the water washing tank 302, and the motor drives the screw shaft to rotate to achieve the effect of removing the slag slurry at the bottom of the water washing tank 302.

[0027] In this embodiment, the water inlet pipe is connected to multiple water inlet branches, and the water outlet pipe is connected to multiple water outlet branches. The water inlet branch is connected to the middle of the water washing tank 302 and is communicated with the water washing tank 302. The water outlet branch is connected to the bottom of the water washing tank 302 and is communicated with the water washing tank. Under the action of the internal circulation pump 305, the water inside the water washing tank 302 can circulate, and the direction of the water circulation is clockwise, so as to achieve the effect of stirring the waste cans entering the water washing tank 302, so that the non-metallic impurities on the waste cans can be separated from them.

[0028] The lower end of the light material mesh belt conveyor 303 is higher than the lower end of the heavy material mesh belt conveyor 304. In this embodiment, the non-metallic impurities float on the upper part of the water washing tank 302 due to their light weight, so the light material mesh belt conveyor 303 can take away the floating non-metallic impurities, and the waste cans will settle in the lower part of the water washing tank 302, and the heavy material mesh belt conveyor 304 can take away the waste cans in the lower part of the water washing tank 302, wherein the light material mesh belt conveyor 303 and the heavy material mesh belt conveyor 304 are both belt conveyors.

[0029] The working principle of the utility model is as follows: after the waste cans are crushed in the crushing process, the crushed waste cans are transported to the magnetic separation process, and the iron impurities in the waste cans are removed in the magnetic separation process, and then transported to the feeding belt conveyor 1, which transports the waste cans to the vibrating feeder 2, and the vibrating feeder 3 evenly feeds the waste cans into the washing machine 3. Under the action of the internal circulation pump 305, the water in the washing tank 302 circulates, and the direction of the water circulation is clockwise, stirring the waste cans entering the washing tank 302, so that the non-metallic impurities in the waste cans are separated from them. Non-metallic impurities float on the upper part of the water washing tank 302 due to their light weight. The light material mesh belt conveyor 303 takes away the floating non-metallic impurities, and a collecting bucket is placed below the light material mesh belt conveyor 303 to collect the non-metallic impurities; the waste can materials are deposited in the lower part of the water washing tank 302, and the heavy material mesh belt conveyor 304 takes away the waste can materials in the lower part of the water washing tank 302.

[0030] The waste cans fall from the discharge end of the heavy material mesh belt conveyor 304, and fall into the spin-drying centrifuge 4 from the feed port of the spin-drying centrifuge 4. Under the centrifugal action, the waste cans are dehydrated and dried once, and the water content of the waste cans is reduced from 80% to 15%. Then, the waste cans fall onto the mesh belt conveyor 5 through the discharge port of the spin-drying centrifuge 4, and are transported to the vibrating fluidized bed 6 by the mesh belt conveyor 5. The waste cans fall from the discharge end of the mesh belt conveyor 5, and enter the vibrating fluidized bed 6 through the feed port of the vibrating fluidized bed 6. Under the action of steam, the vibrating fluidized bed 6 dries the waste cans, and the water content of the waste cans is reduced from 15% to 5%.
