[0002] The circulating fluidized bed boiler is widely used in industry due to its high combustion efficiency and wide fuel adaptability.

[0042] like Figures 3-9 As shown, according to an optional embodiment of the present invention, the return material component includes a return material machine 22, and a return material chamber 23 is opened on the return material machine 22.

[0044] As shown in Figure 5 According to an optional embodiment of the present application, the thickness of the bottom wall of the return material machine 22 decreases from top to bottom, so as to facilitate its insertion into the slag.

[0045] As shown in Figure 5 According to an optional embodiment of the present application, the return material machine 22 is fixed with a guide rail bar, and the rack 25 is slidingly connected to the guide rail bar.

[0046] The guide rail bar has a guiding and limiting function for the rack 25, and the number of guide rail bars is preferably two, forming a stable guiding function.

[0047] As shown in Figure 3 According to an optional embodiment of the present application, the inner bottom wall of the guide hopper 7 is inclined, the inner bottom wall of the feeding channel 6 is inclined, and the inner bottom wall of the receiving cavity 10 is inclined, which can facilitate the slag to slide by its own gravity.

[0048] According to an optional embodiment of the present application, a control system is further included, and the boiler slag feeding system and the bucket elevator 1 are electrically connected to the control system. The control system is provided with a processor for data analysis and component control.

[0049] According to an optional embodiment of the present application, an image acquisition device is further included, and the image acquisition device is provided with a visual module. The image acquisition device can acquire slag image data on the boiler slag feeding system, and the visual module is used to identify the slag image data to determine the amount of slag. When the amount of slag is too much, the control system controls the transportation speed of the boiler slag feeding system to slow down, and when the amount of slag is too little, the control system controls the transportation speed of the boiler slag feeding system to speed up.

[0050] According to an optional embodiment of the present application, the material of the bucket elevator 1 includes stainless steel. The stainless steel preferably includes carbon steel Q235, which has the characteristics of high hardness and high temperature resistance, and can provide good stable support for the bucket elevator 1.

[0051] Implementation process:

[0052] The boiler slag feeding system feeds the slag into the guide hopper 7, and then the slag slides to the bottom wall of the feeding channel 6 and then slides to the hopper, which feeds the slag upward to the discharge part of the bucket elevator 1 at a high position for discharge.

[0053] Since there is a gap between the hopper and the left wall of the machine cavity 3, the slag falling from the feeding channel 6 to the hopper will fall from the gap. At this time, the receiving disc 9 will receive the slag falling from the gap, and the slag will slide along the inclined surface of the receiving cavity 10 into the box cavity 21.

[0054] When one of the conveying rollers rotates, it will drive the linkage shaft 1 5, sprocket 1 29, chain 30, and sprocket 2 31 to rotate clockwise. After the speed change and reversal of the transmission 38, the sprocket 2 31 drives the linkage shaft 2 19, gear 16, movable bar 17, and push cylinder 18 to rotate counterclockwise. The push cylinder 18 slides on the inner wall of the bar hole 15, thereby driving the movable piece 14, the linkage rod 13, and the receiving tray 9 to move back and forth left and right, so that when the hopper passes the same horizontal plane as the receiving tray 9, the receiving tray 9 will move to the left without hindering the upward movement of the hopper. When the receiving tray 9 is located between the two hoppers, it will move to the right to receive the slag.

[0055] The slag in the box chamber 21 gradually increases and enters the return chamber 23. When the detector 24 detects that the height of the slag is higher than the preset value, the control system controls the electromagnet 28 to generate a sufficiently large magnetic repulsive force, so that the rack 25 overcomes the elastic force of the spring 27 and moves left and keeps meshing with the gear 16. The gear 16 drives the rack 25 to move upward, thereby moving the return machine 22 upward, and the pressure bar 35 pushes the guide bucket 7 to rotate counterclockwise, so that the slag on the guide bucket 7 stops falling to the bottom wall of the feeding channel 6, temporarily preventing the furnace from When too much slag enters the hopper, the boiler slag feeding system does not need to be shut down, and the slag continues to be transferred from the boiler slag feeding system to the guide bucket 7. By setting the number and elastic force of the spring three 36, the pressure bar 35 can push the guide bucket 7 to rotate without excessively squeezing the airbag 2 37. When the guide bucket 7 rotates counterclockwise to the point where it can no longer rotate, the pressure bar 35 overcomes the elastic force of the spring three 36 and moves downward, compressing the airbag 2 37. The air in the airbag 2 37 enters the airbag 1 34 through the trachea, causing the airbag 1 37 to be compressed. 4 expands, and the airbag 1 34 pushes the push plate 32 to overcome the elastic force of the spring 2 33 and move rightward, thereby pushing the slag in the return cavity 23 to fall to the bottom wall of the feed channel 6, completing the return of part of the slag in the box cavity 21 to the feed channel 6, so that the hopper can convey the slag. Then the control system controls the electromagnet 28 to cut off the power, and the rack 25 moves to the right and resets under the elastic force of the spring 1 27. The rack 25 is disengaged from the meshing with the permanent magnet 26, and the return machine 22 falls again under the action of its own gravity. The thickness of the bottom wall decreases from top to bottom, and the return machine 22 can be inserted into the slag of the box cavity 21 until the bottom wall of the return machine 22 and the bottom wall of the box cavity 21 are against each other. The guide bucket 7 also reverses and resets under the action of its own gravity, and the pressure strip 35 moves upward and resets under the elastic force of spring three 36, and the push plate 32 moves left and resets under the elastic force of spring two 33. Part of the gas in airbag one 34 flows back to airbag two 37 to expand airbag two 37, completing the reset of the return machine 22 so that the return machine 22 can continue to return the slag.

[0056] The present invention has the following beneficial effects:

[0057] The automatic material receiving is realized, the risk of slag accumulation is reduced, the slag is prevented from accumulating on the bottom wall of the cavity 3 through the gap between the inner wall of the bucket elevator 1 and the hopper when the slag falls from the feeding channel 6, the receiving disc 9 can move left and right, and the receiving disc 9 can automatically give way or receive material during the operation of the hopper, so that the probability of the transmission roller assembly 4 being stuck due to slag accumulation is effectively reduced.

[0058] The driving action of the transmission roller assembly 4 is realized, the power transmission path is formed by the linkage shaft one 5, the linkage shaft two 19, the chain wheel one 29, the chain wheel two 31 and the transmission 38, the transmission roller assembly 4 and the receiving disc 9 are cooperated to act, and the system stability and the control precision are improved.

[0059] The automatic slag return conveying function is realized, the slag accumulation is monitored in real time by the detector 24, it is automatically judged whether the slag needs to be returned, the excess slag can be returned to the bottom of the feeding channel 6 through the push plate 32 and then conveyed by the hopper, and the excess slag is prevented from accumulating in the cavity 21.

[0060] The rack 25 is embedded with the permanent magnet 26 and cooperated with the electromagnet 28, the magnetic control engagement action is realized by combining the spring one 27, the movement of the slag return machine 22 is controlled, the air bag one 34 and the air bag two 37 are communicated through the air pipe, the material pushing action of the push plate 32 and the coordinated reset of the pressing strip 35 and the push plate 32 are realized, and the system has the multi-round continuous automatic slag return capacity.
