Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill for cement production. Background Art

[0002] Ball mills are primarily used in cement production to grind raw materials, crushing and grinding various raw materials into fine powders to meet cement production requirements. The grinding media (such as steel balls) in the ball mill break down and grind the raw materials into a fine powder through friction and impact with the material. This process has a significant impact on cement yield and quality. Raw materials for cement production primarily include limestone, clay, sand, iron ore, and other materials. These raw materials undergo multiple grinding and screening processes in the ball mill to achieve the appropriate fineness and particle size distribution. The ground raw materials then undergo calcination, clinker crushing, and grinding to ultimately produce cement. The performance and operating status of the ball mill have a significant impact on cement production efficiency and product quality. Therefore, regular maintenance and overhaul of the ball mill are essential in cement production to ensure its proper operation and effectiveness. Furthermore, the appropriate ball mill model and parameters should be selected based on production requirements and raw material characteristics to improve production efficiency, reduce energy consumption, and minimize wear.

[0003] The existing ball mill needs to use a container to receive the powder when discharging. When the container is received, the operator needs to manually open the valve of the discharge pipe, and also needs to manually close it when closing it. It is time-consuming to use, which affects the overall production efficiency. Utility Model Content

[0025] The trigger mechanism includes a sliding frame 1001 . An opening slot 1002 is formed inside the sliding frame 1001 . A second connecting tooth plate 1003 is fixedly connected inside the opening slot 1002 .

[0026] One side of the second connecting tooth plate 1003 is meshedly connected with a transmission gear 1004 . Both ends of the transmission gear 1004 are rotatably connected to the inner wall of the opening slot 1002 . One side of the transmission gear 1004 is meshedly connected to the first connecting tooth plate 7 .

[0027] The working principle of this embodiment is as follows: when it is necessary to ball-mill cement raw materials, first open the cover plate 3, and then put the raw materials into the ball mill body 1 through the feed port 2, then wait for the ball mill body 1 to crush the raw materials inside, and then the user moves the material receiving box 8 to the left, so that the material receiving box 8 pushes the trigger plate 9 to move to the left, and the trigger plate 9 moves to the left and then pushes the sliding frame 1001 on the top to move to the left, and the sliding frame 1001 drives the second connecting tooth plate 1003 to move to the left, and the second connecting tooth plate 1003 drives the transmission gear 1004 to move to the left, and the transmission gear 1004 drives the first connecting tooth plate 7 to move to the right, and the first connecting tooth plate 7 drives the blocking plate 5 to move to the right, so that the blocking plate 5 drives the sealing plug 6 to move to the right, at this time, a gap is exposed between the blocking plate 5 and the discharge pipe 4, and the crushed raw materials in the ball mill body 1 will fall into the material receiving box 8 through the gap, and the discharge of the discharge pipe 4 can be achieved by putting in the material receiving box 8, and the user does not need to open it manually, thereby improving the overall efficiency of cement production.

[0028] Example 2

[0029] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 5 A connecting frame 11 is fixedly connected to one side of the bottom of the sliding frame 1001, and a clamping plate 12 is slidably connected to one side of the connecting frame 11. The length of the gap between the clamping plate 12 and the trigger plate 9 is greater than the length of the wall thickness of the material receiving box 8. A tension spring 13 is sleeved on the outer side of the connecting frame 11, and one end of the tension spring 13 is fixedly connected to the clamping plate 12.

[0030] One end of the ball mill body 1 is fixedly connected to a push plate 14 , one end of the push plate 14 passes through the right side of the sliding frame 1001 , and the push plate 14 is slidably connected to the clamping plate 12 .

[0031] When the material receiving box 8 moves to the left and pushes the sliding frame 1001 to move to the left, the push plate 14 will enter the sliding frame 1001 and contact the clamping plate 12. As the sliding frame 1001 continues to move to the left, the clamping plate 12 will be squeezed by the push plate 14 and move downward. After the clamping plate 12 moves downward, it cooperates with the trigger plate 9 to clamp the material box 8. When the material receiving box 8 has received the raw materials and needs to be taken away, it moves out to the right. After the material receiving box 8 moves to the right, the material receiving box 8 will drive the sliding frame 1001 to move to the right through the clamping plate 12, and then the blocking plate 5 moves to the left and resets, so that the blocking plate 5 blocks the outlet pipe 4 through the sealing plug 6 to prevent the raw materials in the ball mill body 1 from flowing out.

[0032] One side of the trigger plate 9 is fixedly connected to a first connecting rod 15 , one side of the first connecting rod 15 is slidably connected to a second connecting rod 16 , and one end of the second connecting rod 16 is fixedly connected to the ball mill body 1 .

[0033] A spring 17 is sleeved on the outer sides of the first connecting rod 15 and the second connecting rod 16 . One end of the spring 17 is fixedly connected to the ball mill body 1 , and the other end of the spring 17 is fixedly connected to the trigger plate 9 .

[0034] By setting the first connecting rod 15, the second connecting rod 16 and the spring 17, the second connecting rod 16 can slide left and right on one side of the first connecting rod 15, and the elastic force of the spring 17 will apply elastic force to the trigger plate 9. Through the connection between the trigger plate 9 and the sliding frame 1001, the second connecting tooth plate 1003 in the sliding frame 1001 and the transmission gear 1004 are connected more tightly.

[0035] A stopper 18 is fixedly connected to the end of the first connecting rod 15 , and a sliding groove 19 for cooperating with the stopper 18 is defined inside the second connecting rod 16 .

[0036] By setting the stop block 18 and the sliding groove 19, after the material receiving box 8 moves to the right, the first connecting rod 15 moves to the right inside the second connecting rod 16. After the stop block 18 at the end of the first connecting rod 15 contacts the stop groove, the trigger plate 9 will stop moving. At this time, the material receiving box 8 will follow and stop moving. At the same time, the push plate 14 will leave from between the clamping plate 12 and the inner wall of the sliding frame 1001. The tension of the tension spring 13 will pull the clamping plate 12 to move upward, so that the clamping plate 12 slides upward from one side of the inner wall of the material receiving box 8 into the sliding frame 1001. At this time, the material receiving box 8 can be pulled out to the right again to pour out the powder in the material receiving box 8, and the next time the empty material receiving box 8 can move to the left again to push the trigger plate 9 to the left.

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
