[0002] The vertical mill in the mineral powder plant is an ideal equipment for the grinding industry that integrates crushing, drying, grinding, and grading and conveying. It has the advantages of high grinding efficiency, low power consumption, and simple process flow.
[0003] In the related technology, when the vertical mill of the mineral powder factory is in production, the iron particles magnetically selected by the return belt iron remover carry dust, and a chute is often used to directly transfer the iron particles magnetically selected by the iron remover into a sealed bag for storage or transportation. In the process of the material falling, due to the large gap between the iron particle chute and the sealed bag, the material will splash out, which will cause the dust carried by the iron particles to fly, and it needs to be cleaned manually from time to time, which brings great pressure to environmental protection work. In the process of transportation or loading, it will also cause dust problems, which is not conducive to the cleanliness of the environment in the production workshop, and the flying dust will also affect the health of the staff, so it needs to be improved.

[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] The present application discloses a device for preventing dust from being generated by the return iron particles of a vertical mill. Figure 1 and Figure 2 , including a return material iron remover 1 and an iron particle chute 2, the return material iron remover 1 is used to magnetically separate iron particles, the magnetically separated iron particles are 1mm-5mm spherical, the iron particle chute 2 is arranged at the outer row of the return material iron remover 1, and a bracket 4 is arranged below the iron particle chute 2, the bracket 4 includes four legs 41, and a fixed bucket 3 is arranged in the bracket 4. In this embodiment, the fixed bucket 3 is a quadrangular pyramid, and the four inner walls of the fixed bucket 3 are inclined toward the center. Each outer wall of the fixed bucket 3 is connected to a connecting rod 31 by welding, and the other end of the connecting rod 31 is connected to the inner wall of the bracket 4 by welding to achieve stable operation of the fixed bucket 3.
[0030] Reference Figure 1 and Figure 2 A sealing cover 5 is provided at the opening of the fixed bucket 3 through bolts. The sealing cover 5 can effectively prevent the problem of dust flying during the material unloading process. One end of the iron particle chute 2 passes through the sealing cover 5 and is inserted into the fixed bucket 3. The iron particle chute 2 and the fixed bucket 3 are set at an angle of 60° so that the material can slide stably, thereby improving the problem of blockage between the fixed bucket 3 and the iron particle chute 2.
[0031] Reference Figure 1 and Figure 2 A discharge port 8 for discharging materials is provided at one end of the fixed bucket 3 away from the iron particle chute 2, and the discharge port 8 is located at the center of the fixed bucket 3. A closed bag for loading materials can be provided at the discharge port 8. A safety hook 6 is provided on the inner side of each leg 41 of the bracket 4. The outer wall of the closed bag is propped open and fixed by the safety hook 6 to increase the volume of the closed bag that can be loaded with materials. A bag mouth fixture 9 for fixing the closed bag is provided at the discharge port 8 to improve the connection stability of the closed bag, prevent the closed bag from falling off, and improve production safety; a circular gate valve 10 is provided above the bag mouth fixture 9, so that when the closed bag is full and replaced, the gate valve 10 is closed so that the material can be buffered in the fixed bucket 3 without stopping work, thereby improving production continuity.
[0032] Reference Figure 1 and Figure 2 A tray 7 for loading a sealed bag is provided below the bracket 4, and the bottom of the sealed bag is located in the tray 7.

[0033] The implementation principle of the dust prevention device for the external discharge of iron particles of the return material of the vertical mill in the embodiment of the present application is as follows: during the operation of the vertical mill, 50% of the return material of the slag vertical mill is iron particles, and 50% is semi-finished products that are difficult to grind, which are mixed with a lot of dust. When the material enters the fixed bucket 3 through the iron particle chute 2, under the shielding of the sealing cover 5, dust can be effectively prevented from flying. The material further enters the sealed bag through the discharge port 8, and is sealed throughout the process, thereby reducing dust. When the sealed bag is full and needs to be replaced, the discharge port 8 is closed through the circular gate valve 10, and the material is buffered in the fixed bucket 3, and then the bag mouth fixer 9 and the safety hook 6 are opened, and the sealed bag is transferred through the tray 7 to replace the new sealed bag. The dust prevention device of the present application can effectively solve the dust problem and improve production continuity and safety.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
