[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a sodium bicarbonate drying fluidized bed dust recovery device, comprising a collection box 1, with a cover plate 2 detachably installed on the top of the collection box 1. The cover plate 2 and the collection box 1 are detachably connected using existing technology, which will not be described in detail here. A filter bag 3 is detachably installed on the inner wall of the collection box 1. When the dust-laden airflow passes through the filter bag 3, the dust particles are trapped in the filter bag 3 due to inertial collision, Brownian diffusion, and sieving effect. The purified gas is discharged from the bag. A fixed plate 4 is fixedly connected to the surface of the collection box 1, and a movable plate 5 is slidably connected to the top of the fixed plate 4. The movable plate 5 has openings on it. The moving plate 5 has a slanted groove, which can be used to squeeze the round rod 8 to make it move. The inner wall of the moving plate 5 is connected to a connecting block 6 through and fixedly connected to it. The inner wall of the connecting block 6 is connected to a fastening bolt 7 through and threadedly connected to it. The inner wall of the connecting block 6 has a groove corresponding to the fastening bolt 7, which can satisfy the fastening bolt 7 to move along the inner wall of the connecting block 6. The inner wall of the moving plate 5 is connected to a round rod 8 through and slidably connected to it. The bottom end of the round rod 8 is fixedly connected to a slider 9. The slider 9 mainly connects the return spring 10 and the insert block 11. The inner wall of the slider 9 is provided with a limit mechanism. The top of the cover plate 2 is provided with a pressure relief component.

[0019] The limiting mechanism includes a plug 11, which is slidably connected to the inner wall of the slider 9. The slider 9 has a slot, which allows the plug 11 to move back and forth along the slot. The front end of the plug 11 is elastically connected to the slider 9 through a return spring 10.

[0020] Reference Figure 1 and Figure 6The pressure relief assembly includes a connecting pipe 12, which is fixedly connected to the top of the cover plate 2. The cover plate 2 is connected to the connecting pipe 12, allowing gas to enter the connecting pipe 12. The top of the connecting pipe 12 is elastically connected to a piston pipe 14 via a positioning spring 13. The contact surface between the piston pipe 14 and the connecting pipe 12 is made of rubber material, which can ensure the sealing during its sliding process. A pressure relief hole 15 is provided on the outer wall of the connecting pipe 12, through which gas can be discharged. The top of the connecting pipe 12 is fixedly connected to one end of the positioning spring 13. When the piston pipe 14 moves upward, it will stretch the positioning spring 13. When resetting, the elastic force of the positioning spring 13 will bring the piston pipe 14 back to its original position. The other end of the positioning spring 13 is fixedly connected to the inner side wall of the piston pipe 14. The piston pipe 14 passes through and the piston is connected to the inner wall of the connecting pipe 12.

[0021] Reference Figures 2-4 The front end of the insert block 11 is fixedly connected to one end of the return spring 10. When the insert block 11 moves forward, it will compress the return spring 10. When resetting, the elastic force of the return spring 10 will carry the insert block 11 to reset. The other end of the return spring 10 is fixedly connected to the inner wall of the front end of the slider 9. The insert block 11 is inserted into the outer wall of the upper edge of the cloth bag 3. The upper edge of the cloth bag 3 is made of plastic material, and a corresponding slot for the insert block 11 is opened at the upper edge, so that the insert block 11 can be inserted into the slot to limit the position of the cloth bag 3.

[0022] Reference Figures 4-5 The slider 9 is slidably connected to the inner wall of the fixed plate 4, the round rod 8 passes through and is slidably connected to the inner wall of the fixed plate 4, the connecting block 6 is slidably connected to the top of the fixed plate 4, and the fastening bolt 7 is inserted into the top of the fixed plate 4. The fixed plate 4 has two sets of slots, which are the same as the fastening bolt 7, so that the fastening bolt 7 can be inserted.

[0023] Working principle: First, when disassembling the cloth bag 3, simply rotate the fastening bolt 7 to separate it from the top slot of the fixing plate 4. Then, move the connecting block 6 to the right, moving the moving plate 5 and the fastening bolt 7 to the right. The slot of the moving plate 5 presses against the round rod 8, causing the round rod 8 to bring the slider 9 and the insert block 11 closer together, separating the insert block 11 from the slot of the cloth bag 3. This simultaneously releases the limiting position of multiple cloth bags 3, allowing the cloth bags 3 to be moved upwards from the collection box 1. (The text abruptly ends here, seemingly mid-sentence.) Figure 3 In the initial state, simply follow the steps above. If it is necessary to release the limit of a single cloth bag 3, simply move the insert block 11 by hand and compress the reset spring 10 to separate the insert block 11 from the slot of the single cloth bag 3, and then the single cloth bag 3 can be replaced.

[0024] When the entire device experiences high pressure, the pressure inside the collection box 1 will push the piston tube 14 upward and stretch the positioning spring 13. When the piston tube 14 moves to the inner wall of the top of the connecting pipe 12, the gas will be discharged outward from the pressure relief hole 15. When the pressure decreases, the reverse elastic force of the positioning spring 13 will use the piston tube 14 to return to the initial state downward.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
