[0004] This patent can effectively avoid slagging on the chute surface and damage to the chute, and the chute is easy to replace and maintain. However, the existing mobile slag chute will be subjected to the vibration and impact force generated by the operation of the rotary kiln or the flow of slag during use, which will damage the equipment and reduce the service life of the equipment. Therefore, we have proposed a new type of mobile slag chute for rotary kiln. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 - Figure 4As shown, the utility model provides a mobile slag chute for a rotary kiln, including a base 1, the two side surfaces of the base 1 are respectively connected to a first support frame 2 and a second support frame 3, the bottom of the base 1 is connected to a shock-absorbing protection component 4, the shock-absorbing protection component 4 includes a moving seat 401, the surface of the moving seat 401 is plugged with two groups of sliding rods 402, the surfaces of the two groups of sliding rods 402 are connected to two groups of moving blocks 403, the sliding rod 402 is located between the two groups of moving blocks 403 and is sleeved with a first spring 404, the top of each group of moving blocks 403 is connected to a first rotating shaft 405, the surface of the first rotating shaft 405 is connected to a connecting rod 406, and one side of the connecting rod 406 is connected to the second rotating shaft. Shaft 407, the four corners of the surface of the movable seat 401 are connected with fixed blocks 408, and a second spring 409 is provided inside each group of fixed blocks 408. The top of the second spring 409 is connected with a top block 410. The base 1 is rotatably connected with the connecting rod 406 through the second rotating shaft 407, and the connecting rod 406 is rotatably connected with the movable block 403 through the first rotating shaft 405. The outer surface of the sliding rod 402 is in contact with the inner wall of the movable block 403, and a sliding connection is formed between the movable block 403 and the sliding rod 402. An elastic structure is formed between the movable block 403 and the first spring 404, and an elastic structure is formed between the fixed block 408 and the second spring 409.

[0025] The effect achieved by the entire embodiment 1 is that when the mobile slag chute is in use, it can slide on the guide rail through the moving seat 401, driving the wear-resistant steel plate 505 to be located below the rotary kiln discharge port (not shown in the figure), receiving the kiln slag discharged from the rotary kiln discharge port, and guiding the kiln slag to the water quenching slag pool (not shown in the figure) through the wear-resistant steel plate 505. When receiving, the kiln slag will be subjected to the vibration and impact force generated by the operation of the rotary kiln or the flow of molten slag. At this time, the impact force will cause the entire device to move downward, and the second rotating shaft 407 will rotate with the connecting rod 406, so that the connecting rod 406 can push the moving block 403 to slide on the surface of the sliding rod 402 through the first rotating shaft 405, thereby achieving a shock absorption effect. At the same time, the top block 410 will also squeeze the second spring 409 to improve the shock absorption effect, thereby avoiding damage to the equipment during use and increasing the service life of the equipment.

[0026] Example 2, as Figure 1 and Figure 5 As shown, the surface of the second support frame 3 is connected to the disassembly assembly 5, and the disassembly assembly 5 includes a fixed box 501, and a bidirectional screw 502 is inserted into the interior of the fixed box 501. Two groups of movable plates 503 are provided on the surface of the bidirectional screw 502, and the inner sides of the two groups of movable plates 503 are connected to plug blocks 504. The surface of the fixed box 501 is provided with wear-resistant steel plates 505, and slots 506 are provided on the bottom of both sides of the wear-resistant steel plates 505. A threaded connection is formed between the bidirectional screw 502 and the movable plate 503, and a plug-in connection is formed between the plug block 504 and the slot 506.

[0027] The effect achieved by the entire embodiment 2 is that when the wear-resistant steel plate 505 needs to be replaced, the bidirectional screw 502 can be rotated in the opposite direction, so that the bidirectional screw 502 and the two sets of movable plates 503 rotate simultaneously, and drive the insert block 504 to be pulled out from the slot 506, and then the wear-resistant steel plate 505 can be removed, and the new wear-resistant steel plate 505 can be placed on the surface of the fixed box 501. At this time, the bidirectional screw 502 can be rotated forward, so that the two sets of movable plates 503 push the two sets of insert blocks 504 to move inward at the same time, driving the insert block 504 to be inserted into the slot 506 to achieve the installation and fixation of the wear-resistant steel plate 505, avoiding the problem that the existing device does not fix the wear-resistant steel plate 505 when it is installed, thereby making the wear-resistant steel plate 505 not stable when used.

[0028] Working principle: When the mobile slag chute is in use, it will be subjected to the vibration and impact force generated by the operation of the rotary kiln or the flow of slag. At this time, the impact force will cause the entire device to move downward, thereby pushing the first spring 404 through the connecting rod 406 to achieve a shock-absorbing effect. The second spring 409 can also enhance the shock-absorbing effect, thereby avoiding damage to the equipment during use and increasing the service life of the equipment. When replacing the wear-resistant steel plate 505, the plug block 504 can be pulled out of the slot 506 by rotating the thread, and then the wear-resistant steel plate 505 can be replaced and fixed by inserting the plug block 504 into the slot 506, thereby avoiding the problem that the existing device does not fix the wear-resistant steel plate 505 when it is installed, thereby making the wear-resistant steel plate 505 not stable when used.
