[0013] How to use the dust removal device: Start the exhaust fan, the air in the workshop enters the filter chamber through the air inlet pipe, the air entering the filter chamber is filtered by the mesh belt and then discharged from the air outlet pipe, and the particles in the air are intercepted on the mesh belt on one side of the air inlet pipe.

[0014] After the device has been used for a period of time, the driving assembly drives the lower wheel to rotate, and the lower wheel drives the upper wheel to rotate through the mesh belt. When the mesh belt rotates, the brushing and collecting assembly can brush and collect the particles intercepted by the mesh belt.

[0015] When the lower wheel rotates, the swing assembly swings, and when the swing assembly swings, the sliding shaft is located in the arc groove.

[0016] When the mesh belt is seriously blocked, the ventilation volume of the mesh belt is reduced, and the pressure difference in the filter chambers on the front and rear sides of the mesh belt increases. After the pressure difference in the filter chambers on the front and rear sides of the mesh belt increases, the mesh belt part between the upper wheel and the lower wheel has a tendency to move toward the outlet duct. During the swinging process of the swinging assembly, when the vertical slot corresponds to the second slide slot left and right, the sliding shaft corresponds to the vertical slot up and down. Under the pulling force of the mesh belt, the upper wheel and the sliding shaft move downward, and the sliding shaft moves into the vertical slot. Then, as the swinging assembly continues to swing, the sliding shaft can drive the upper wheel to continue to move downward. After the lower wheel moves downward, the elastic support assembly is compressed. At the same time, a gap is generated between the upper end of the mesh belt and the upper end of the filter chamber, and the pressure difference in the filter chambers on the front and rear sides of the mesh belt is reduced. During the swinging restoration process of the swinging assembly, when the vertical slot corresponds to the second slide slot again, the upper wheel quickly moves upward and restores and tensions the mesh belt under the action of the elastic support assembly. When the mesh belt is tensioned, the particles on the mesh belt can be shaken off, thereby playing a role in dredging the mesh belt.

[0017] When the dust removal device is used in an ammonium perchlorate production workshop, the box is fixed on the packaging process side of the ammonium perchlorate production workshop, the air inlet pipe is facing the packaging process of the ammonium perchlorate production workshop, the exhaust fan is started, and the air in the workshop enters the filter chamber through the air inlet pipe. The air entering the filter chamber is filtered by the mesh belt and then discharged from the air outlet pipe. The ammonium perchlorate in the workshop air is intercepted on the mesh belt on one side of the air inlet pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This device uses a rotatable mesh belt to filter the air in the workshop. The ammonium perchlorate intercepted by the mesh belt can be brushed and collected by the brush collection component, which can reduce the content of ammonium perchlorate in the air and thus improve the air quality in the workshop.

[0020] 2. When the mesh belt is seriously blocked, the cooperation between the upper wheel, the swing assembly and the elastic support assembly can make the upper wheel quickly return to the original position and tension the mesh belt after it goes down. When the mesh belt is tensioned, the ammonium perchlorate on the mesh belt can be shaken off, thereby playing the role of unblocking the mesh belt.

[0021] 3. When the mesh belt is unblocked, the air is filtered by the filter, which can effectively collect the ammonium perchlorate in the air and avoid waste of raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

A top wheel 12 is rotatably arranged on the upper end of the support plate 11, and the upper end of the top wheel 12 is in rolling contact with the lower end of the upper wheel 10.

[0039] When the dust removal device is applied to an ammonium perchlorate production workshop, the box 1 is fixed on one side of the packaging process of the ammonium perchlorate production workshop, the air inlet pipe 4 faces the packaging process of the ammonium perchlorate production workshop, the exhaust fan 6 is started, and the air in the workshop enters the filter chamber through the air inlet pipe 4. The air entering the filter chamber is filtered by the mesh belt 9 and then discharged from the air outlet pipe 5. The ammonium perchlorate in the workshop air is intercepted on the mesh belt 9 on one side of the air inlet pipe 4. A brushing and collecting component is arranged in the filter chamber below the air inlet pipe 4, and the brushing and collecting component can brush and collect the ammonium perchlorate intercepted by the mesh belt 9 when the mesh belt 9 rotates.

[0040] The brushing and collecting assembly includes a fixed block 27, which is fixed in the filter cavity on the front side of the mesh belt 9.

The particles brushed away by the brush 28 pass through the air holes 29 and the dust collection box 26 and enter the dust collection box 30. The particles entering the dust collection box 30 are intercepted by the filter element provided in the dust collection box 30.

[0043] Embodiment 2: Based on Embodiment 1, refer to Figure 1 and Figure 7 As shown, a filter screen 7 is fixed inside the air outlet pipe 5 .

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a swing assembly is arranged in the driving cavity, and the lower wheel 8 can drive the swing assembly to swing. An arc groove 22 is provided at the upper end of the swing assembly. A sliding shaft 21 is coaxially connected to the upper wheel 10, and the sliding shaft 21 is located in the arc groove 22. A vertical groove 23 is provided on the swing assembly below the arc groove 22, and the vertical groove 23 is connected to the arc groove 22.

[0045] When the swing assembly swings, the sliding shaft 21 is located in the arc groove 22. After the upper wheel 10 moves downward, the sliding shaft 21 can enter the vertical groove 23.

[0046] After the sliding shaft 21 enters the vertical groove 23, when the swing assembly swings, the sliding shaft 21 can drive the upper wheel 10 to continue to move downward.

[0047] The swing assembly includes a rotating plate 18 , an arc-shaped groove 22 is formed at the upper end of the rotating plate 18 , and a vertical groove 23 is formed on the rotating plate 18 below the arc-shaped groove 22 .

[0048] The lower end of the rotating plate 18 is rotatably connected to the lower end of the supporting plate 16 via the fixed shaft 17. The arc groove 22 is concentric with the fixed shaft 17.

[0049] A torsion spring is sleeved on the fixed shaft 17, one end of the torsion spring is fixedly connected to the support plate 16, and the other end of the torsion spring is fixedly connected to the rotating plate 18. Under the action of the torsion spring, the rotating plate 18 can maintain a vertical state.

[0050] The support plate 16 is fixed in the driving cavity, and a vertical second slide groove 25 is provided at the upper end of the support plate 16, and the sliding shaft 21 is slidably arranged in the second slide groove 25. A connecting shaft 34 is rotatably arranged on the support plate 16, and the connecting shaft 34 is coaxially fixedly connected with the lower wheel 8, and the connecting shaft 34 is fixedly connected with one end of the rotating rod 19, and the other end of the rotating rod 19 is rotatably connected with the slider 20, and a vertical first slide groove 24 is provided on the rotating plate 18 above the fixed shaft 17, and the slider 20 is slidably arranged in the first slide groove 24.

[0051] When the lower wheel 8 rotates, the connecting shaft 34 drives the rotating rod 19 and the sliding block 20 to rotate, and the sliding block 20 slides in the first sliding groove 24 when rotating. At the same time, the rotating plate 18 swings back and forth. When the rotating plate 18 swings, the sliding shaft 21 is located in the arc groove 22.

[0052] When the mesh belt 9 is seriously clogged, the ventilation volume of the mesh belt 9 is reduced, and the pressure difference in the filter chamber on the front and rear sides of the mesh belt 9 increases. After the pressure difference in the filter chamber on the front and rear sides of the mesh belt 9 increases, the mesh belt 9 portion between the upper wheel 10 and the lower wheel 8 has a tendency to move toward the air outlet duct 5. During the swinging process of the rotating plate 18, when the vertical groove 23 corresponds to the second slide groove 25 left and right, the sliding shaft 21 corresponds to the vertical groove 23 up and down. Under the pulling force of the mesh belt 9, the upper wheel 10 and the sliding shaft 21 move downward, and the sliding shaft 21 moves into the vertical groove 23.

[0053] Then, as the rotating plate 18 continues to swing, the rotating plate 18 drives the sliding shaft 21 to continue to move downward in the second slide groove 25, and the sliding shaft 21 can drive the upper wheel 10 to continue to move downward. During the downward movement of the upper wheel 10, the upper wheel 10 drives the supporting plate 11 and the light rod 13 downward through the top wheel 12, and the spring 15 is compressed. At the same time, a gap is generated between the upper end of the mesh belt 9 and the upper end of the filter chamber. After the gap is generated between the upper end of the mesh belt 9 and the upper end of the filter chamber, the pressure difference in the filter chamber on the front and rear sides of the mesh belt 9 is reduced.

[0054] During the swinging and restoring process of the rotating plate 18, when the vertical groove 23 corresponds to the second chute 25 again, the pressure difference in the filter chamber on both sides of the mesh belt 9 is reduced, so the upper wheel 10 quickly moves upward to restore and tension the mesh belt 9 under the elastic force of the spring 15. When the mesh belt 9 is tensioned, the particles on the mesh belt 9 can be shaken off, thereby playing the role of unblocking the mesh belt 9. In this embodiment, the particles are ammonium perchlorate flying in the production workshop.

[0055] When the mesh belt 9 is unblocked, the air is filtered by the filter screen 7, which can effectively collect the particulate matter in the air and avoid the waste of raw materials.

[0056] After the sliding shaft 21 is located in the vertical groove 23, in order to facilitate the sliding shaft 21 to drive the upper wheel 10 to continue to move downward when the rotating plate 18 rotates, the diameter of the sliding shaft 21 is set to be smaller than the groove width of the vertical groove 23. When the groove wall of the vertical groove 23 that is away from the swinging direction of the rotating plate 18 contacts the sliding shaft 21, the rotating plate 18 and the groove wall of the vertical groove 23 that contacts the sliding shaft 21 are in an inclined state. Subsequently, during the swinging process of the rotating plate 18, the groove wall of the vertical groove 23 that is in an inclined state and contacts the sliding shaft 21 makes it easier for the sliding shaft 21 to drive the upper wheel 10 to move downward.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

The present invention relates to a trend that during the swinging process of the swinging assembly, when the vertical slot (23) corresponds to the second slide slot (25) left and right, the sliding shaft (21) corresponds to the vertical slot (23) up and down, and under the pulling force of the mesh belt (9), the upper wheel (10) and the sliding shaft (21) move downward, and the sliding shaft (21) moves into the vertical slot (23). Then, as the swinging assembly continues to swing, the sliding shaft (21) can drive the upper wheel (10) to continue to move downward. After the lower wheel (8) moves downward, the elastic support assembly is compressed. At the same time, a gap is generated between the upper end of the mesh belt (9) and the upper end of the filter chamber, and the pressure difference in the filter chamber on the front and rear sides of the mesh belt (9) is reduced. During the swinging process of the swinging assembly, when the vertical slot (23) corresponds to the second slide slot (25) again, under the action of the elastic support assembly, the upper wheel (10) quickly moves upward to restore and tension the mesh belt (9). When the mesh belt (9) is tensioned, the particles on the mesh belt (9) can be shaken off, thereby playing the role of clearing the mesh belt (9).

8. Based on the application of the dust removal device according to claim 1 in an ammonium perchlorate production workshop, It is characterized in that The box body (1) is fixed on one side of the packaging process of the ammonium perchlorate production workshop, the air inlet pipe (4) is directed toward the packaging process of the ammonium perchlorate production workshop, the exhaust fan (6) is started, and the air in the workshop enters the filter chamber through the air inlet pipe (4). The air entering the filter chamber is filtered by the mesh belt (9) and then discharged from the air outlet pipe (5), and the ammonium perchlorate in the workshop air is intercepted on the mesh belt (9) on one side of the air inlet pipe (4).
