Description

Technical Field

[0001] The present application relates to the technical field of boiler grates, and in particular to a boiler grate plate anti-deviating mechanism. Background Art

[0002] Boiler grates are essential components in boilers, supporting fuel and facilitating the combustion process. They typically consist of a series of strips or plates made of heat-resistant metal. These structures are arranged in a specific pattern to form a flat or slightly inclined surface upon which the fuel is placed for combustion. Grate designs can be either fixed or movable. Movable grates can rotate the fuel through movement, helping to improve combustion efficiency and reduce ash formation.

[0003] For example, a modular grate fixed end structure with publication number CN215723246U includes a bracket, a plurality of reciprocating grates are arranged in the bracket, two slides are arranged in the bracket, two first springs are fixedly connected to the opposite sides of the two slides, and the first springs are fixed to the bracket, a rack is fixedly connected to the opposite sides of the two slides, two rotating holes are provided on the outer wall of one side of the bracket, a rotating shaft is rotatably connected in each of the two rotating holes, one end of the rotating shaft is keyed to a gear, and the gear is meshed with the rack, and a fixing mechanism is provided on the outer side of the two rotating shafts for fixing the rotating shaft. Through the use of the slide and the first spring, after the furnace is stopped, the fixing mechanism no longer fixes the rotating shaft. At this time, the slide will be pulled to move under the action of the first spring, so that the slide is separated from the reciprocating grate, and foreign matter at the fixed end can be cleaned.

[0004] In the above-mentioned related technologies, since the grate plates are subjected to the influence of high temperature, mechanical vibration and other factors for a long time, wear will occur between two adjacent grate plates. When the spacing becomes larger, the grate plates will be offset. This offset will not only affect the uniform distribution of fuel and combustion efficiency, but may also cause damage to the grate structure and affect the safe operation of the boiler.

[0023] The boiler grate is set on the chain, and the chain and sprocket cooperate. At the same time, a plurality of mounting shafts are set on the chain. The grate is passed through the mounting shafts. The chain is driven to rotate by the rotation of the sprocket, and then the grate can be rotated.

[0024] The following is combined with Figure 1-4 This application is described in further detail.

[0025] The embodiment of the present application discloses a boiler grate anti-deviating mechanism. Figure 1 A boiler grate anti-deviation mechanism includes a mounting plate 1 arranged on a chain, a mounting shaft is fixed on the mounting plate 1, and a grate plate 11 is slidably connected to the mounting shaft, and a pushing component 2 is provided on the mounting plate 1. The pushing component 2 is used to push the grate plates 11 at the edge to move toward the middle, so that the position of the grate plates 11 with a larger spacing can be adjusted, the gap between the grate plates 11 can be reduced, and then the deviation of the grate plates 11 can be reduced.

[0026] The pushing assembly 2 includes a pushing block 21 slidably connected to the mounting plate 1 and a pushing surface 22 arranged on the pushing block 21. At the same time, a mounting groove 12 is opened on the mounting plate 1. The pushing block 21 is slidably connected in the mounting groove 12, and the pushing surface 22 abuts against the inner wall of the mounting groove 12. When the pushing block 21 slides along the opening direction of the mounting groove 12, under the action of the pushing surface 22, the grate piece 11 on the mounting shaft will be pushed to move, and then the spacing between the grate pieces 11 will be reduced, thereby reducing the offset of the grate pieces 11.

[0027] The fixing assembly 3 is provided on the mounting plate 1, and the fixing assembly 3 is used to fix the position of the pushing block 21 after adjustment, and then the grate plate 11 can be prevented from moving on the mounting shaft; the fixing assembly 3 includes a fixing plate 31 slidably connected to the mounting block and a fixing rod 32 fixed on the fixing plate 31. A plurality of fixing grooves 13 are opened on the side of the pushing block 21 away from the pushing surface 22, and a plurality of fixing grooves 13 are provided along the length direction of the pushing block 21. At the same time, a fixing spring 33 is provided on the mounting plate 1, and one end of the fixing spring 33 is fixed on the mounting plate 1, and the other end is fixed on the fixing plate 31. The fixing spring 33 is used to push the fixing rod 32 to move into the fixing groove 13, so that the position of the pushing block 21 can be fixed. When the fixing block is in the fixing groove 13 at different positions, the pushing block 21 is in different positions, and then when the pushing block 21 is adjusted to different gaps, the fixing assembly 3 can still fix the position of the pushing block 21.

[0028] A control assembly 4 is mounted on the frame. This assembly is used to control the movement of the fixing plate 31 away from the push block 21, thereby disengaging the fixing rod 32 from the fixing slot 13. This facilitates the sliding of the pushing block 21 along the length of the mounting slot 12, thereby facilitating adjustment of the position of the grate 11. Because the control assembly 4 is fixed to the frame, when the grates rotate, the mounting plate 1 on any grate corresponds to the control assembly 4, allowing the control assembly 4 to adjust the position of the pushing block 21 and the fixing rod 32, thereby enhancing convenience during use.

[0029] The control assembly 4 includes a control screw 41 rotatably connected to the frame, a control plate 42 rotatably connected to the control screw 41, and a control block 43 fixed to the control plate 42. The control screw 41 is threadedly connected to the frame. By rotating the control screw 41, the control plate 42 and the control block 43 can be driven to move away from or closer to the push block 21. In this embodiment, the moving direction of the control plate 42 is parallel to the moving direction of the push block 21.

[0030] When the control assembly 4 and the pushing assembly 2 correspond to each other, the control block 43 and the gap between the fixed plate 31 and the pushing block 21 correspond to each other, and then when the control screw 41 drives the control block 43 and the control plate 42 to move, the control block 43 will first move between the fixed plate 31 and the pushing block 21, at this time the control block 43 will push the fixed plate 31 to move away from the pushing block 21, so that the fixing rod 32 disengages the fixing groove 13, the fixing spring 33 is compressed, and then continue to move, so that the control plate 42 abuts against the pushing block 21, and at this time pushes the fixed plate 31 to continue to move in the opposite direction, and the control plate 42 pushes the pushing block 21 to move, under the action of the moving surface, the grate plate 11 can be pushed to move, thereby facilitating the adjustment of the gap between the grate plates 11, so that when the grate plates 11 are worn, they can still be used after the gap adjustment is completed. In addition, since the control assembly 4 is arranged on the frame, on the one hand, multiple groups of grates can be adjusted in sequence through the control assembly 4, and on the other hand, the position of the grate plates 11 can be adjusted more conveniently.

[0031] A control rubber 14 is provided on the control block 43, and the control rubber 14 is tilted. Then, when the control block 43 moves, the tilted control rubber 14 pushes the fixing plate 31 to move away from the pushing block 21, thereby facilitating the separation of the fixing rod 32 and the fixing groove 13, and then facilitating the control plate 42 to push the pushing block 21 to move, thereby making it more convenient to use.

[0032] When the cam 432 is in the unlocking state, the cam 432 is in the unlocking state, and the cam 432 is in the unlocking state, so that the cam 432 is unlocked.

[0033] An adjustment component 5 is provided on the mounting portion 431, and the adjustment component 5 is used to adjust the position of the control portion 432. The adjustment component 5 includes an adjustment plate 51 rotatably and slidingly connected to the mounting portion 431 and an adjustment screw 52 rotatably connected to the adjustment plate 51. The adjustment screw 52 is threadedly connected to an adjustment rod 53, and the adjustment rod 53 is slidably connected to the frame. When the adjustment plate 51 extends out of the mounting portion 431, the adjustment plate 51 will push the control portion 432 to move, and then the reset spring 15 will be in a stretched state, so that when the control plate 42 and the control portion 432 move, the control rubber 14 can push the fixed plate 31 to move.

[0034] When the adjusting plate 51 is slidably connected to the mounting portion 431 and the adjusting rod 53 is slidably connected to the frame, when the control plate 42 moves, the adjusting plate 51 and the adjusting rod 53 are driven to move at the same time, and then the control rubber 14 is abutted against the fixing plate 31, and then it is convenient to push the fixing plate 31 to move. When the fixing rod 32 and the fixing groove 13 are separated, the control screw 41 is continued to be rotated, and the control screw 41 drives the control plate 42 to move, so that the control plate 42 abuts against the pushing block 21. At this time, the control plate 42 will push the pushing block 21 to move. During the movement of the pushing block 21, the grate plate 11 will be pushed to move, and finally the gap between the grate plates 11 can be adjusted. When the position adjustment of the grate piece 11 is completed, the position of the control plate 42 remains unchanged. At this time, the adjusting screw 52 rotates, which will drive the adjusting plate 51 to move into the mounting portion 431. Then, under the action of the return spring 15, the control portion 432 is driven to move in the direction away from the fixed portion. At this time, the control rubber 14 will separate from the fixed plate 31, and under the action of the fixing tube spring, the fixing rod 32 is pushed to move into the fixing groove 13 to fix the position of the push block 21. Then the grate piece 11 rotates, and the other mounting plates 1 correspond to the control components 4. The position of the push blocks 21 on the remaining mounting plates 1 can be adjusted, so that it is convenient to adjust the gap between the grate pieces 11 during use.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
