Two left and right water tanks 8 are provided on the right side of the frame 1. The two water tanks 8 are respectively located below the two water filter plates 14. The two water tanks 8 are fixedly connected by bolts. The left water tank 8 is fixedly connected to the right side of the frame 1 by bolts. The water tank 8 The upper inner part is connected with two front and rear filter screens 82, and a gap is left between the filter screen 82 and the inner bottom of the water tank 8 for impurities to flow out. A collection frame 81 that can be withdrawn outward is slidably provided in the water tank 8. The collection frame 81 in the left water tank 8 is withdrawn to the left, and the collection frame 81 in the right water tank 8 is withdrawn to the right. The collection frame 81 is located between the front and rear filter screens 82 and fits with the filter screen 82. The two collecting frames 81 are connected with a valve pipe 83 on the side away from each other, and the two water tanks 8 are connected with a valve pipe 2 84 located above the collecting frame 81 on the side away from each other. The two filter screens 82 in the left water tank 8 are connected with gauze 85 on the side away from each other. The upper inner part of the collecting frame 81 is connected with a filter screen 2 86, and the inner bottom of the collecting frame 81 is designed as an inclined surface. In order to guide impurities to the valve pipe 83, a spray assembly is provided on the water tank 8, and the spray assembly is used to spray water filtered by the filter screen 82 into the material frame 2 and the screw conveyor 12 to clean the materials. The spray assembly includes a water pump 9, a hose 91, a float 92, a water pipe 10, a nozzle 11 and a nozzle 2 16.

The two nozzles 16 extend into the screw conveyor 12. The two nozzles 16 are respectively located above the two water filter plates 14. The water spray port on the nozzle 2 16 above the left water filter plate 14 is smaller than the water spray port on the nozzle 2 16 above the right water filter plate 14, so as to achieve different cleaning intensities and effects.

[0022] First, pour water into the water tank 8, and then put the tungsten ore into the material frame 2. At the same time, the control motor 51, the water pump 9 and the screw conveyor 12 work, and the water pump 9 on the left water tank 8 works, and the water in the left water tank 8 is input into the water pipe 10 through the left hose 91, and the water is input into the nozzle 11 through the water pipe 10, and the water is sprayed into the material frame 2 toward the lower left through the nozzle 11 to clean the tungsten ore in the material frame 2. The motor 51 drives the rotating shaft 5 to drive the cam 6 to rotate. When the longer end of the cam 6 rotates to contact the upper shaking plate 3, the cam 6 continues to rotate to push the upper shaking plate 3 to swing upward, and the upper spring 4 is stretched accordingly. When the longer end of the cam 6 rotates to disengage from the upper shaking plate 3, the upper shaking plate 3 is pulled downward by the reset action of the upper spring 4. When the longer end of the cam 6 rotates to contact the lower shaking plate 3, the cam 6 continues to rotate to push the lower shaking plate 3 to swing downward, and the lower spring 4 is compressed accordingly. When the longer end of the cam 6 rotates to disengage from the lower shaking plate 3, the lower shaking plate 3 is pushed to swing upward under the reset action of the lower spring 4. Repeating this process can make the shaking plate 3 shake up and down, and the shaking of the shaking plate 3 up and down can shake the tungsten ore apart, so that the tungsten ore can be evenly distributed, ensuring that each ore can be effectively cleaned and improving the cleaning effect. The tungsten ore that has completed the first cleaning falls into the screw conveyor 12 through the feed channel 21, and the tungsten ore and wastewater can be transported to the right through the screw conveyor 12. The dirtier wastewater falls into the front and rear two filter screens 82 in the left water tank 8 through the left water filter plate 14, and the cleaner wastewater falls into the front and rear two filter screens 82 in the right water tank 8 through the right water filter plate 14. The water pump 9 on the right water tank 8 works, and the water in the right water tank 8 is input into the second nozzle 16 through the right hose 91, and the water is sprayed downward into the screw conveyor 12 through the second nozzle 16, so as to perform a secondary cleaning of the tungsten ore. In the process of being conveyed to the right by the screw conveyor 12, the tungsten ore can rub against each other, and perform a second deeper cleaning, so as to ensure that the impurities on the surface of the ore are completely removed, thereby significantly improving the quality of the ore. The cleaned tungsten ore is discharged to the right from the screw conveyor 12, and the water in the tungsten ore can be discharged to the left through the drainage hole 15 to achieve dehydration. The fine tailings falling from the water filter plate 14 fall onto the second filter screen 86 in the collection frame 81, and impurities such as soil enter the collection frame 81 through the second filter screen 86. The waste water falling into the water tank 8 can be filtered by the filter screen 1 82 and the gauze 85, and the impurities are blocked between the front and rear filter screens 1 82. The floating block 92 can make the hose 91 float at a higher position in the water tank 8, so that the hose 91 extracts the relatively clean waste water in the upper half of the water tank 8, realizing efficient water circulation, greatly reducing the discharge of waste water, saving water resources, and reducing the impact on the environment. The valve on the valve pipe 2 84 can be opened to discharge the waste water in the water tank 8 to replace clean water, and the impurities in the collection frame 81 can be discharged by opening the valve pipe 1 83, and the collection frame 81 can be pulled out of the water tank 8 to collect and clean the tailings on the filter screen 2 86.

[0023] See also Figure 1-Figure 2 The top of the shaking plate 3 is connected with convex strips 31 at intervals. When the shaking plate 3 shakes up and down, the convex strips 31 are driven to shake up and down, hitting the tungsten ore and frictionally contacting with the tungsten ore, thereby enhancing the cleaning effect and removing impurities on the surface of the ore.

[0024] See also Figure 2 A roller brush 7 located between two cams 6 is connected to the rotating shaft 5. When the rotating shaft 5 rotates, the roller brush 7 is driven to rotate. The rotation of the roller brush 7 can scrub the tungsten ore, thereby improving the ore washing effect, thoroughly removing impurities on the surface of the ore, further improving the quality of the ore, and ensuring the efficiency and thoroughness of the cleaning process.

[0025] See also Figure 1 Two front and rear baffles 13 are connected between the tops of the two water tanks 8. The front and rear baffles 13 are respectively located directly above the front and rear filter screens 82 on both sides. The baffles 13 can block the wastewater discharged from the water filter plate 14 so that the wastewater falls accurately between the front and rear filter screens 82 on both sides, thereby ensuring effective filtration of the wastewater.

[0026] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
