Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to an automatic discharging mechanism for an intermittent ball mill. Background Art

[0002] Intermittent ball mill is a kind of grinding equipment widely used in the industrial field. It is mainly used for crushing and grinding materials. It achieves the purpose of crushing by impacting and grinding the materials through the grinding media (such as steel balls, steel rods or ceramic balls) loaded inside the rotating inner cylinder. Ball mills are used in many industries such as mineral processing, building materials, chemicals, metallurgy, electric power, ceramics, silicate products, etc.

[0003] During the grinding process of the intermittent ball mill, a cover plate is usually installed in the discharge port set on the upper side of the outer arc surface of the inner cylinder to prevent the material from spilling out of the discharge port during the grinding process of the intermittent ball mill. When the intermittent ball mill needs to discharge, the cover plate is replaced with a grid plate. At this time, the gap on the upper end of the grid plate will allow the fine powder material to be thrown out of the inner cylinder and the grinding media (balls, columns) will remain in the inner cylinder of the ball mill, thereby realizing the discharge work;

[0004] When using the existing intermittent ball mill, although it can perform grinding and discharging work by replacing the cover plate and the grid plate, the switching process will cause powder spillage and pollution, low manual production efficiency, difficulty in maintaining personnel occupational health, and the cover plate is heavy, making it difficult to scale up the equipment. Therefore, we propose an automatic discharging mechanism for an intermittent ball mill. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an intermittent ball mill automatic discharging mechanism, which realizes grinding and discharging work by adjusting the position of the insert plate, basically eliminates the spillage of materials, and realizes semi-automatic operation. Personnel do not need to perform high-intensity handling, and the equipment can be large-scale, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: an automatic discharging mechanism for an intermittent ball mill, comprising an inner cylinder and a discharging assembly;

[0007] Discharging assembly: It includes a cover plate, a grid plate and a protective cover. The cover plate is arranged in the discharge port arranged on the upper side of the outer arc surface of the inner cylinder. A grid plate is arranged on the lower side of the cover plate, and a protective cover is arranged on the upper end of the cover plate. By adjusting the position of the plug plate, the grinding and discharging work can be realized, which basically prevents the spillage of materials and realizes semi-automatic operation. Personnel do not need to perform high-intensity handling, and the equipment can be large-scale.

[0008] Furthermore, the discharging assembly also includes an adjustment plate and an insert plate. The adjustment plate is slidably connected to the inner wall of the protective cover. The lower end of the adjustment plate is respectively provided with an insert plate. The insert plates are installed in conjunction with the gaps provided at the upper end of the grid plate to seal the grid plate.

[0009] Furthermore, it also includes a cylinder, which is arranged at the upper end of the protective cover, and the lower end of the telescopic end of the cylinder is fixedly connected to the upper end of the adjustment plate, so that the position of the plug plate can be adjusted.

[0010] Furthermore, pneumatic nozzles are provided in the avoidance grooves opened on the upper sides of the left and right ends of the protective cover, and the pneumatic nozzles can spray compressed air to reduce material accumulation and blockage.

[0011] Furthermore, a connecting seat is provided in the connecting groove opened in the middle of the left and right ends of the protective cover, and an exhaust pipe is provided in the exhaust port opened at the left end of the left connecting seat.

The air intake pipe may be used to balance the negative pressure generated after the air is extracted from the protective cover to maintain the pressure balance inside and outside the protective cover.

[0013] Furthermore, flanges are provided on the side of the outer arc surface of the air inlet pipe and the air exhaust pipe away from the inner center of the inner cylinder, so that the air inlet pipe and the air exhaust pipe can be connected to external equipment.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the intermittent ball mill automatic discharging mechanism has the following advantages:

[0015] After the insert plate is pulled out, the gap on the upper end of the grid plate will allow the fine powder material to be thrown out from the inner cylinder, and the grinding medium (balls, columns) will remain in the inner cylinder.

The lower end of the adjusting plate 24 is provided with an inserting plate 25. The inserting plates 25 are all arranged in cooperation with the gaps provided at the upper end of the grid plate 22. After the insert plate 25 is pulled out, the gap on the upper end of the grid plate 22 will allow the fine powder material to be thrown out from the inner cylinder 1, and the grinding medium (balls, columns) will remain in the inner cylinder 1. At the same time, the external exhaust equipment will generate suction to extract the ground material to the next level equipment. By adjusting the position of the insert plate 25, the grinding and discharging work can be realized, which basically eliminates the spillage of materials and realizes semi-automatic operation.

Through the regulation of the external solenoid valve, the cylinder 6 starts to run, and the telescopic end of the cylinder 6 extends, so that the adjustment plate 24 drives the plug-in plate 25 to move downward, and finally the plug-in plate 25 is inserted into the gap set at the upper end of the grid plate 22 in turn, thereby blocking the grid plate 22.

[0023] Among them, pneumatic nozzles 7 are provided in the avoidance grooves opened on the upper sides of the left and right ends of the protective cover 23. The pneumatic nozzles 7 can spray compressed air to reduce material accumulation and blockage.
