Description

Technical Field

[0001] The utility model relates to the field of polishing powder processing devices, and more specifically to a polishing powder grinding and impurity removal device. Background Art

[0002] A polishing powder grinding and impurity removal device is a device specifically designed to grind and remove impurities from rare earth polishing powder. The working principle of polishing powder impurity removal is to select an appropriate impurity removal method based on the nature and characteristics of the impurities, thereby separating the impurities from the polishing powder to improve the purity and quality of the polishing powder. In practical applications, multiple impurity removal methods are often combined to achieve optimal impurity removal results.

[0003] In the polishing powder grinding and impurity removal device, the mesh screening efficiency is not high during the screening of impurities in the rare earth polishing powder block, which will cause the impurities to stick to part of the finished powder. After this part of the impurities is transferred, the finished powder that is stuck to the impurities cannot be effectively separated and recovered, resulting in a waste of raw materials, which is not conducive to ensuring the benefits of the enterprise. Therefore, it is necessary to design a polishing powder grinding and impurity removal device with an auxiliary screening device to solve the above problems. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of this utility model is to provide a polishing powder grinding and impurity removal device to solve the problem that after some impurities are transferred, the finished powder with impurities attached cannot be effectively separated and recovered, resulting in waste of raw materials.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] A polishing powder grinding and impurity removal device comprises an equipment body, the upper end of the equipment body is fixedly connected to a grinding upper bin, the lower end of the equipment body is fixedly connected to a discharge middle bin, a impurity removal lower bin is arranged between the equipment body and the discharge middle bin, an electric conveyor belt is installed at the inner end of the lower impurity removal bin, the electric conveyor belt comprises a mesh impurity removal screen layer, the left and right ends of the mesh impurity removal screen layer are symmetrically fixedly connected to the electric conveyor belt, a impurity removal mechanism that cooperates with the electric conveyor belt is arranged in the impurity removal lower bin, the impurity removal mechanism comprises a plurality of load-bearing vertical plates distributed at the front and rear sides of the electric conveyor belt, the end of the load-bearing vertical plate close to the electric conveyor belt is fixedly connected to a vibrator, and the output end of the vibrator is fixedly connected to a flexible hammer contact head.

[0007] Furthermore, the front and rear ends of the mesh surface impurity removal screen layer are symmetrically connected with reinforced side strips, and one end of the reinforced side strip close to the mesh surface impurity removal screen layer is fixedly connected with a plurality of spring cross members.

[0008] Furthermore, a plurality of spring cross members are interconnected with the mesh surface impurity removal screen layer, and the plurality of spring cross members are distributed equidistantly from left to right.

[0009] Furthermore, the flexible hammer contact head contacts the outer side wall of the reinforced side strip, and the lower end of the load-bearing vertical plate on the same side is fixedly connected with an inclined bent material guide plate.

[0010] Furthermore, the upper parts of the two inclined-bent material guide plates are connected to each other, and the two inclined-bent material guide plates respectively pass through the inner side of the electric conveyor belt.

[0011] Furthermore, the lower end of the middle discharge bin is fixedly connected with a discharge opening, and the inclined bent guide plate cooperates with the discharge opening.

[0012] Furthermore, a plurality of supporting columns are provided at the lower end of the equipment body and the lower end of the electric conveyor belt.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In this scheme, when the rare earth polishing material passes through the mesh impurity removal screen layer in the electric conveyor belt, the two sets of vibrators in the impurity removal mechanism are installed on the load-bearing vertical plate and their output ends are facing the sides of the reinforced side strips on both sides of the electric conveyor belt. The vibration force output by the vibrator is transmitted to the reinforced side strips through the flexible hammer contact head, which can provide continuous vibration or elasticity for the mesh impurity removal screen layer, helping to disperse the rare earth polishing material and impurities that are stuck together, making the material looser, and facilitating the impurities to be more thoroughly separated through the mesh impurity removal screen layer. By reducing the loss of finished powder, the waste of raw materials is reduced, and the reliability of the equipment and the continuity of production are improved.

[0015] (2) At the same time, multiple spring cross members are set at the connection between the mesh surface impurity removal screen layer and the electric conveyor belt. The multiple spring cross members can transmit the vibration force generated by the vibrator more evenly to the positions on both sides of the mesh surface impurity removal screen layer, so that the horizontal screening efficiency of the mesh surface impurity removal screen layer is higher. In addition, the flexible hammer contact head on the contact surface between the vibrator and the electric conveyor belt can reduce the hard contact with the outer wall of the electric conveyor belt, thereby ensuring the service life of the vibrator and the electric conveyor belt.

[0016] (3) When the rare earth polishing material passes through the electric conveyor belt and falls into the middle discharge bin and is discharged through the discharge port, two inclined curved guide plates arranged in a triangular tilted state can be set in the mesh surface impurity removal screen layer. The inclined curved guide plates can play a role in diverting and guiding the material, so that the discharge port is not prone to blockage risks during the discharge process.
