Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, specifically to a discharge structure for a grinding mill. Background Technology

[0002] Grinding mills are widely used in the grinding and processing of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. After the raw materials are ground into powder, they are discharged from the mill's outlet. Compared to granular raw materials, powdered materials are easier to discharge. However, in actual production, large amounts of powdered material often accumulate into clumps, increasing the likelihood of blockage at the mill's outlet. If not manually cleared, the raw material will accumulate inside the mill and cannot be discharged in a timely manner, affecting normal production operations and increasing the risk of equipment damage.

[0003] Currently, most existing grinding mills have a hopper-shaped discharge section. However, during the discharge process, powder easily bridges and clumps inside the hopper, causing blockages and affecting the discharge. Generally, when bridging and clumping occur in the discharge hopper, it is necessary to manually tap the outside of the hopper to loosen the clumps and allow them to flow out through vibration. However, manual tapping is not only inconvenient, but each tap can only be applied to one side of the discharge hopper, thus affecting the efficiency of breaking up the clumps. Therefore, we propose a new discharge structure for grinding mills. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a discharge structure for a grinding mill, which solves the problems mentioned in the background section.

A spring is installed on the outside of the slide rod. A horizontal plate is fixedly installed at one end of the slide rod. A striking head is fixedly installed on both sides of the horizontal plate. The striking head cooperates with the discharge pipe.

[0011] This utility model provides a discharge structure for a grinding mill, which has the following beneficial effects:

[0012] 1. The discharge structure of this grinding mill, through the arrangement of mounting frame, limiting plate, gear ring, guide rod, rotating groove, motor frame, stepper motor, gear, convex plate, concave frame, sliding rod, abutment plate, spring, horizontal plate and striking head, can simultaneously strike the four sides of the discharge pipe when powder bridging and clumping occurs inside the discharge pipe. This causes vibration in the discharge hopper and discharge pipe, breaking up the powder bridging and clumping inside the discharge hopper and discharge pipe, thereby improving the efficiency of solving powder clogging.

The discharge structure of this grinding mill, through the setting of guide rods, guide bearings, ball grooves and supporting balls, can effectively improve the smoothness and stability of the gear ring rotation.

Gear 10 meshes with gear ring 5. Several protruding plates 11 are fixedly installed inside gear ring 5. Several concave frames 12 are fixedly installed on the outside of discharge pipe 2. Sliding rods 13 are slidably installed inside concave frames 12. Sliding rods 13 cooperate with protruding plates 11. A stop plate 14 is fixedly installed on the outside of sliding rods 13. A spring 15 is installed on the outside of sliding rods 13. The stop plate 14 cooperates with spring 15. A horizontal plate 16 is fixedly installed at one end of sliding rod 13. A striking head 17 is fixedly installed on both sides of the horizontal plate 16. One end of the striking head 17 is covered with rubber. The striking head 17 cooperates with discharge pipe 2. The rubber covering one end of the striking head 17 is used to reduce the noise when it strikes the discharge hopper 1.

[0023] A guide bearing 19 is provided on the outer side of the guide rod 6. The rotating groove 7 cooperates with the guide bearing 19. A ball groove 20 is provided inside the top of the guide rod 6. A supporting ball 21 is rolled inside the ball groove 20. The supporting ball 21 cooperates with the gear ring 5.

[0024] Two guide rods 18 are fixedly installed on one side of the horizontal plate 16. The guide rods 18 are slidably connected to the inside of the concave frame 12. The inside of the concave frame 12 is provided with holes that cooperate with the slide rod 13 and the guide rods 18. The function of the guide rods 18 is to guide and limit the horizontal plate 16.

[0025] In summary, when powder bridging occurs inside the discharge hopper 1, the discharge structure of this grinding mill can be used to drive the gear 10 to rotate by turning on the stepper motor 9. The gear 10 meshes with the gear ring 5 and drives it to rotate. As the gear ring 5 rotates, the inner convex plate 11 intermittently contacts the sliding rod 13 around the discharge pipe 2 and pushes it to slide. Then, the outside of the discharge pipe 2 can be knocked by the knocking head 17. The vibration generated by the knocking can break up the powder bridging inside the discharge hopper 1, thereby preventing the powder bridging from causing blockage inside the discharge hopper 1.
