Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing machines, and particularly relates to a cleaning device for an ore dressing machine. Background Technique

[0002] There are many devices for separating small ores, including a beneficiation centrifuge disclosed in a Chinese patent with the patent publication number CN206046274U, which includes a feed pipe, a frame, a tailings tank, a driving motor, a hollow shaft and beneficiation components. The beneficiation components are divided into two layers, an inner cylinder and an outer cylinder. The characteristics are as follows: the inner cylinder is a cone, which reduces the water consumption and also reduces the driving force requirement; the outer wall and the inner wall of the inner cylinder are both conical, the inner wall is provided with annular grid bars, there are many small holes on the inner wall, a closed water jacket is formed between the outer cylinder and the inner cylinder, the water inlet pipe enters the interlayer between the outer wall and the inner wall of the inner cylinder through the hollow shaft, and then enters the cavity of the inner wall cone through the small holes on the inner wall.

[0003] However, during the operation of the centrifuge provided in the above patent, mineral particles with a relatively large specific gravity will be stored in the annular grid bars. At the same time, the existing annular grid bars are not convenient to disassemble, which is not conducive to the staff to clean the accumulated ores. Although the backflush water can wash away the stored ores, because the backflush water holes are distributed at intervals, there are still some mineral particles accumulated. Even more, under the action of centrifugal force, the mineral particles are very likely to block the backflush water holes at the annular grid bars, affecting the flow of the backflush water. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a cleaning device for an ore dressing machine.

[0005] A cleaning device for an ore dressing machine is placed on the ore dressing machine. The top of the ore dressing machine is provided with a feed pipe, the feed pipe extends into the inner cylinder, the inner wall of the inner cylinder is provided with a screening groove, the wall of the screening groove is provided with backflush water through holes, and a cleaning block is arranged in each screening groove. The cleaning block is connected with a support rod through a connecting rod, and a through groove allowing the cleaning block to pass through is arranged on the end cover at the top of the ore dressing machine.

[0006] Further, a limiting block is arranged at the top of the support rod. The limiting block includes a top plate and a bottom plate. The length of the bottom plate is less than that of the through groove, and the length of the top plate is greater than that of the through groove.

[0007] Further, a pull ring is arranged above the limiting block.

[0008] Further, an eccentric wheel is rotatably installed on the end cover, and the far center end of the eccentric wheel abuts against the top plate.

[0009] Further, inclined surfaces are arranged at both ends of the cleaning block.

[0010] Due to the adoption of the above technical solution, the beneficial technical effects of the present utility model are as follows: When ores are blocked in the screening trough of the present utility model, the support rod is inserted into the inner cylinder in an inclined state, and then the cleaning block is horizontally moved to insert it into the screening trough. Then, the motor of the ore dressing machine is started to drive the inner cylinder to rotate. During the rotation of the inner cylinder, the cleaning block clears the ores blocked in the screening trough. After the cleaning is completed, the motor stops working, the support rod is horizontally moved to move the cleaning block out of the screening trough, and then the support rod is pulled upward obliquely to move the entire cleaning device out, without affecting the normal ore dressing work of the ore dressing machine.

Detailed Description of the Preferred Embodiment

[0015] In order to more clearly illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0016] According to Figures 1 - 3 As shown, a cleaning device for an ore dressing machine is placed on the ore dressing machine 1. The top of the ore dressing machine 1 is provided with a feed pipe 2, the feed pipe 2 extends into the inner cylinder 3, the inner wall of the inner cylinder 3 is provided with a screening trough 4, the wall of the screening trough 4 is provided with a backflush through hole, and each screening trough 4 is provided with a cleaning block 5. The cleaning block 5 is connected to the support rod 7 through a connecting rod 6. The end cover 9 on the top of the ore dressing machine 1 is provided with a through groove 8 allowing the cleaning block 5 to pass through.

[0017] In the above specific technical solution, when the ore is blocked in the screening tank 4, the support rod 7 is inserted into the inner cylinder 3 in an inclined state, and then the cleaning block 5 is laterally moved to insert it into the screening tank 4. Then, the motor of the ore separator 1 is started to drive the inner cylinder 3 to rotate. During the rotation of the inner cylinder 3, the cleaning block 5 clears the ore blocked in the screening tank 4. After the cleaning is completed, the motor stops working, the support rod 7 is laterally moved to move the cleaning block 5 out of the screening tank 4, and then the support rod 7 is pulled upward obliquely to move the cleaning device out as a whole, without affecting the normal ore separation work of the ore separator 1. Then, the cover plate is placed on the through groove 8 to ensure the sealing performance during the normal operation of the centrifuge.

[0018] A limit block is provided at the top of the support rod 7. The limit block includes a top plate 10 and a bottom plate 11. The length of the bottom plate 11 is less than that of the through groove 8, and the length of the top plate 10 is greater than that of the through groove 8. The bottom plate 11 moves laterally in the through groove 8, and the lateral movement direction only includes the direction of inserting or moving away from the screening tank 4 by the cleaning block 5, so as to ensure that the cleaning block 5 inserts into or moves away from the screening tank 4.

[0019] A pull ring 12 is provided above the limit block, which is convenient for the staff to pull out the cleaning device.

[0020] An eccentric wheel 13 is rotatably installed on the end cover 9. The far center end of the eccentric wheel 13 abuts against the top plate 10. When the cleaning device needs to be installed, the eccentric wheel 13 is rotated so that the eccentric wheel 13 does not affect the normal installation of the limit block. When the cleaning device is inserted into the inner cylinder 3, the limit block is laterally moved to drive the cleaning block 5 to insert into the screening tank 4. Then, the eccentric wheel 13 is rotated so that the far center end of the eccentric wheel 13 tightly abuts against the limit block, thereby positioning the limit block. When the cleaning block 5 is inserted into the screening tank 4, the groove wall of the through groove 8 and the eccentric wheel 13 cooperate to position the limit block.

[0021] Inclined surfaces 14 are provided at both ends of the cleaning block 5, which are convenient for shoveling out the ore in the screening tank 4.

[0022] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
