[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to solve the technical problems in the background technology, the following material buffer device in the cement mill is provided:

[0025] Combine Figure 1-Figure 4 As shown, the material buffer device in the cement mill provided by the present invention includes a buffer frame 1, which is arranged on the inner side of the shell 5. The buffer frame 1 includes a buffer rod 11, and a buffer bottom plate 12 is provided at the bottom end of the buffer rod 11. The buffer bottom plate 12 can buffer the contacted material and reduce the flow rate of the material. A movable mechanism 4 is provided on the side of the buffer rod 11. The movable mechanism 4 can improve the buffering effect of the buffer frame 1. The buffer rod 11 is provided with multiple buffer mechanisms 2 for buffering materials on the top surface of the buffer bottom plate 12, and a ball bouncing mechanism 3 is provided on the bottom surface of the buffer rod 11. The ball bouncing mechanism rebounds the contacted steel ball. The buffer mechanism 2 includes a buffer plate 1 21, a buffer plate 2 22 and a buffer plate 3 23. The buffer plate 1 21 is fixed on the side of the buffer rod 11. The buffer plate 1 21 is Inclined mirror distribution, the buffer plate 1 21 with a mirror-inclined distribution can buffer the gathered flowing materials, and a buffer plate 22 is provided below the buffer plate 1 21. The buffer plate 22 is in an inverted V-shaped structure. The buffer plate 22 with an inverted V-shaped structure can buffer and divert the materials buffered and gathered by the buffer plate 1 21. Connecting rods 221 are provided at both ends of the buffer plate 22. The connecting rod 221 is fixedly connected to the buffer rod 11. A buffer plate 3 23 is provided below the buffer plate 22. The buffer plate 3 23 is fixedly arranged on the side of the buffer rod 11. The buffer plate 3 23 is in an inclined mirror distribution. The buffer plate 3 23 with an inclined mirror distribution can buffer the materials gathered and in contact with the buffer plate 2 22, and further buffer the materials. A material discharge port is left between the buffer plates 1 21 and directly between the buffer plates 3 23;

[0026] When the buffer device is in use, the high-speed flowing material in the cement mill will pass through the buffer mechanism 2. The buffer plate 1 21, the buffer plate 2 22 and the buffer plate 3 23 in the buffer structure can perform multi-stage buffering and deceleration on the material. The material buffered by the buffer mechanism 2 will fall on the buffer bottom plate 12. The material will enter the cement mill after being buffered by the buffer bottom plate 12. In this way, the flow rate of the material flow can be reduced, the crushing effect of the material in the cement mill can be increased, and the material crushing effect can be improved.

[0027] In this embodiment, a guide plate 13 is provided on the top surface of the buffer bottom plate 12. The top surface of the guide plate 13 is inclined. The guide plate 13 can ensure that the material can enter the cement mill in time after the buffer bottom buffers the material.

[0028] like Figure 1-Figure 2 As shown, based on the above embodiment, this embodiment further provides the following content:

[0029] In order to further improve the effect of material crushing in the cement mill, this embodiment provides the following design:

[0030] In this embodiment, the ball-bouncing mechanism 3 includes a spring 31 and a spring plate 32. The spring 31 is provided on the bottom surface of the buffer base plate 12. The springs 31 are arranged in an array. The spring plate 32 is provided at the bottom end of the spring 31. The edge of the spring plate 32 is inclined downward. The spring plate 32 with an inclined downward edge can prevent steel balls from accumulating in the gap between the spring plate 32 and the buffer base plate 12. With the assistance of the springs 31 arranged in an array, the spring plate 32 can eject the steel balls in contact with the spring plate 32, thereby increasing the activity in the mill and improving the crushing effect of the steel balls on the materials.

[0031] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following content:

[0032] In order to further improve the effect of the device in buffering materials, this embodiment provides the following design:

[0033] In this embodiment, the buffer rod 11 engages and slides with the housing 5, and the movable mechanism 4 is mirror-distributed on the outside of the housing 5. Through the engagement and sliding of the buffer rod 11 and the housing 5, the buffer frame 1, the buffer mechanism 2, and the pinball mechanism 3 can be raised and lowered in the middle of the housing 5.

[0034] In this embodiment, a movable groove 51 is opened inside the shell 5, and the movable mechanism 4 includes a movable rod 41 and a movable block 42. The movable rod 41 is arranged on the outside of the shell 5, and a movable block 42 is provided in the middle of the movable rod 41. The movable block 42 is fixedly connected to the buffer rod 11, and the movable block 42 is engaged and slid with the movable groove 51. By engaging and sliding with the movable block 42 and the movable groove 51, the lifting distance of the buffer rod 11 can be limited, and the stability of the buffer rod 11 during lifting and lowering can be improved.

[0035] As an improvement to the above-mentioned solution, a spring 2 43 is provided on the top and bottom surfaces of the movable block 42, the movable rod 41 is arranged corresponding to the buffer rod 11, and a cross bar 44 is provided between the movable rods 41. The spring 2 43 can support and pull the movable block 42 when the movable block 42 slides in the movable groove 51, thereby increasing the buffering effect of the buffer frame 1 and the buffer mechanism 2 on the material.

[0036] When using:

[0037] First, the material buffer device is arranged at the part where the material flows in the cement mill. When the material flows through the middle of the shell 5, the flowing material will pass through the buffer mechanism 2. At this time, the buffer plate 1 21 and the buffer plate 3 23 with mirror-image inclined distribution and the buffer plate 2 22 with inverted V-shaped structure in the buffer structure can perform multi-stage buffering and deceleration on the passing material, thereby reducing the flow rate of the material. The material buffered by the buffer mechanism 2 will fall on the guide plate 13 above the buffer bottom plate 12. After the guide plate 13 further buffers the material, the material will slide into the cement mill. Under the buffering of the material by this device, the flow rate of the material flow is reduced, the crushing effect of the material in the cement mill is increased, and the material crushing effect is improved.

[0038] During use:

[0039] During the process of the steel balls crushing materials in the cement mill, the steel balls are likely to come into contact with the spring plate 32. At this time, the spring plate 32, supported by the springs 31 distributed in the array, can eject the steel balls that come into contact with the spring plate 32, thereby increasing the activity in the mill and improving the crushing effect of the steel balls on the materials.
