This technology discloses "including a frame, a support plate is fixedly arranged horizontally inside, a discharge port is opened on the side wall of the frame, and a switch component for opening and closing the discharge port is provided at the discharge port; a conveying component is arranged on the support plate, and the top of the conveying component is connected to a feed pipe, which passes through the top of the frame upward and is connected to the outside; a water filter component is arranged on one side of the conveying component, the water filter component is connected to the discharge port, and a water storage component is provided on one side of the water filter component; a water sprinkling component, the input end of which is arranged in the water storage component, and the output end extends into the conveying component through the inner wall of the frame. The utility model solves the problem of poor ore cleaning effect in the prior art due to water being separated without sufficient contact with the ore, and is suitable for ore cleaning."

[0004] When the existing ore cleaning device is in use, after the ore is put into the feed pipe, it is located at the bottom of the conveying pipe. The water sprayed from the sprinkler assembly may not be able to clean the bottom of the ore, resulting in residual mud and sand in the ore. At the same time, the cleaning process often requires a large water pressure. When the water pressure is relatively low, the mud and sand may not be discharged from the conveying pipe with the water flow in time, and will accumulate at the bottom of the conveying pipe and be discharged together with the ore, causing the cleaned ore to adhere to mud and sand again.

[0027] An ore cleaning device comprises a bracket 1.

[0028] In this embodiment: after investigation, the public (announcement) number: CN220942156U discloses a new type of ore cleaning device. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "after the ore is put into the feed pipe, it is located at the bottom of the conveying pipe. The water sprayed from the sprinkler assembly may not be able to clean the bottom of the ore, resulting in residual mud and sand in the ore. At the same time, the cleaning process often requires a large water pressure. When the water pressure is relatively low, the mud and sand may not be discharged from the conveying pipe in time with the water flow, and thus accumulate at the bottom of the conveying pipe and be discharged together with the ore, resulting in the ore after cleaning being stuck with mud and sand again." In terms of combined use, this problem is obviously a problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, the inner cylinder 2 and the spiral blade 7 are added to the present application document;

[0029] More specifically:

[0032] In this embodiment, after the ore is put into the inner cylinder 2, the water flow in the nozzle 13 and the centrifugal force of the inner cylinder 2 throw the mud and sand from the holes in the inner cylinder 2 to the inner wall of the outer cylinder 3, thereby realizing the separation of mud and sand from the ore. By arranging the spiral blades 7 on the outer wall of the inner cylinder 2, the mud and sand on the inner wall of the outer cylinder 3 are cleaned while the inner cylinder 2 rotates, so that the mud and sand can be discharged from the device in time, thereby avoiding the situation where the ore after cleaning is adhered to mud and sand again due to the accumulation of mud and sand.

[0033] In an optional embodiment, the outer diameter of the spiral blade 7 is consistent with the inner diameter of the outer cylinder 3 , and the length of the spiral blade 7 is consistent with the length of the outer cylinder 3 .

[0034] In this embodiment, the edge of the spiral blade 7 can contact the inner wall of the outer cylinder 3, and the spiral blade 7 can clean the inner wall of the outer cylinder 3 while rotating.

[0035] In an optional embodiment: the top of the outer cylinder 3 is provided with through holes evenly distributed laterally, and the through holes of the outer cylinder 3 are each provided with a nozzle 13, and the right side of the bottom end of the outer cylinder 3 is provided with a sewage outlet, and the inner wall of the sewage outlet is fixedly connected to the outer side of the sewage pipe 8.

[0036] In this embodiment, the nozzle 13 is arranged in the hole of the outer cylinder 3 so that the rotation of the spiral blade 7 will not affect the water spraying of the nozzle 13 .

[0037] According to the above content, in order to recover small particles of ore in the mud and sand, the water tank 11 is also provided with a sliding connection fixing frame 14, a vibration motor 16 is fixed inside the fixing frame 14 by bolts, and a screen 15 is fixed at the bottom of the fixing frame 14 by bolts.

[0043] The working principle and use process of the present invention are as follows: when in use, the motor 4 is started, and the motor 4 drives the main gear 5 to rotate. Since the motor 4 is fixed on the bracket 1, the main gear 5 can drive the driven gear 6 to rotate, and the driven gear 6 drives the inner cylinder 2 to rotate, and the water pump 10 is started. The water pump 10 transports water from the water tank 11 to the water storage box 12 through the water inlet pipe 9, and sprays water to the inner cylinder 2 through the nozzle 13 at the bottom of the water storage box 12. Ore is put into the device from the feeding hopper 17. The ore entering the inner cylinder 2 is thrown from the hole of the inner cylinder 2 to the inner wall of the outer cylinder 3 under the action of the water flow and the centrifugal force of the inner cylinder 2. To achieve the separation of mud and ore, while the inner cylinder 2 rotates, the spiral blades 7 arranged on the outer wall of the inner cylinder 2 clean the mud on the inner wall of the outer cylinder 3, and enable the mud to be discharged from the sewage pipe 8. The vibration motor 16 is started, and the vibration motor 16 transmits the vibration to the screen 15 through the fixed plate. Since the sewage pipe 8 is located above the water tank 11, the discharged mud and water can return to the water tank, and the small particles of ore therein can be screened out by the vibration of the screen 15. When the small particles of ore are collected to a certain extent, the screen 15 is taken out of the water tank 11 through the handle of the fixing frame 14 to recycle the small particles of ore.
