Description
Technical Field
[0001] This utility model belongs to the field of industrial silicon production technology, specifically relating to an environmentally friendly dust removal device for industrial silicon production. Background Technology
[0002] Baghouse dust collectors are commonly used in industrial silicon production for dust removal. They are a type of dry dust filtration device, suitable for capturing fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.
[0003] Pulse-jet baghouse dust collectors are a type of dust removal equipment widely used in baghouse dust collectors. However, existing pulse-jet baghouse dust collectors experience continuous dust particle impacts on the filter bags during operation, leading to filter bag wear. With increasing usage time, the filtration efficiency of the filter bags gradually decreases, and problems such as pulse valve malfunction and equipment aging may also occur.
[0004] Secondly, improper operation or inadequate equipment maintenance during the cleaning of dust from industrial silicon ash hoppers can lead to dust emissions that negatively impact the surrounding environment and worker health. Based on these issues, this application proposes an environmentally friendly dust removal device for industrial silicon production to address these problems. Utility Model Content
[0005] The purpose of this invention is to provide an environmentally friendly dust removal device for industrial silicon production. This device helps dust particles in a baghouse dust collector to fall off more easily, thereby improving dust removal efficiency. Vibration also promotes gas flow inside the baghouse dust collector, allowing the gas to pass through the filter bags more evenly, further enhancing the dust removal effect. Secondly, vibration reduces filter bag clogging because it helps dust fall off the filter bags more easily, thus reducing filter bag resistance and extending their service life. Furthermore, the conveying device ensures worker health while transporting collected dust and waste to designated locations for easy recycling, reducing production costs.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] An environmentally friendly dust removal device for industrial silicon production includes a chassis, a dust hopper fixed to the lower end of the chassis, a crossbar fixed to the lower end inside the chassis, an arc-shaped plate rotatably connected to the outer side of the crossbar, a rotating part rotatably located inside the dust hopper, the rotating part being adapted to the arc-shaped plate and positioned at the lower end of the arc-shaped plate, a motor and a transmission assembly assembled at the lower end inside the chassis, and the motor and transmission assembly, as well as the rotating part and the transmission assembly, being interconnected, with a conveying assembly assembled on one side of the transmission assembly.
[0008] In one preferred embodiment of this utility model, the transmission assembly includes a bracket, a first rotating rod, a first gear, a second rotating rod, a second gear, a third gear, a third rotating rod, and a fourth gear. The bracket is fixed to the lower end inside the chassis. The first rotating rod is rotatably connected to the lower end inside the bracket. The first rotating rod is fixedly connected to the output end of the motor and is also connected to the output assembly. The first gear is fixed to the outside of the first rotating rod. The second rotating rod is rotatably connected to the inside of the bracket. The second gear is fixed to the lower end outside the bracket and meshes with the first gear. The third gear is fixed to the upper end outside the second rotating rod. The third rotating rod is rotatably connected to the upper end inside the bracket and is fixedly connected to the rotating part. The fourth gear is fixed to the outside of the third rotating rod and meshes with the third gear.
[0009] In one preferred embodiment of the present invention, the conveying assembly includes a screw conveyor and a drive shaft. The screw conveyor is fixed to the lower end of the machine housing. A dust outlet is provided at the end of the screw conveyor away from the motor. The drive shaft is rotatably connected to the inside of the screw conveyor. The screw conveyor and the first rotating rod are fixedly connected, and the dust outlet and the drive shaft are adapted to each other. A detachable cover plate is installed at the upper end of the screw conveyor.
[0010] In one preferred embodiment of the present invention, the ash hopper is equipped with a filter plate, and the filter plate has uniformly sized round holes inside.
[0011] In one preferred embodiment of the present invention, the cross-sectional shape of the arc-shaped plate is arc-shaped.
[0012] In one preferred embodiment of the present invention, the outer surface of the arc-shaped plate is provided with a rubber layer.
[0013] In one preferred embodiment of the present invention, the upper end of the screw conveyor is equipped with a detachable cover plate.
[0014] The technical effects achieved by this utility model are as follows:
[0015] After the motor is started, the rotating part is driven to rotate through the transmission component. The rotating part intermittently drives the arc plate to knock on the ash hopper. The resulting vibration can reduce the maintenance cost of the bag filter, reduce the frequency of filter bag replacement, and reduce the number of times the equipment needs to be cleaned.
[0016] This invention uses a conveying component to effectively collect and transport dust and waste from the dust collector, avoiding the hassle of manual cleaning and handling, and improving work efficiency.
[0017] This invention reduces noise and increases wear resistance by setting a rubber layer on the outer side of the curved plate. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an environmentally friendly dust removal device for industrial silicon production includes a housing 10. A dust hopper 15 is fixed to the lower end of the housing 10. A crossbar 19 is fixed to the lower end inside the housing 10. An arc-shaped plate 18 is rotatably connected to the outer side of the crossbar 19. A rotating part 16 rotates inside the dust hopper 15, adapting to the arc-shaped plate 18 and located at the lower end of the arc-shaped plate 18. A motor 11 and a transmission assembly 20 are assembled at the lower end inside the housing 10, and the motor 11 and the transmission assembly 20, as well as the rotating part 16 and the transmission assembly 20, are interconnected. A conveying assembly 30 is assembled on one side of the transmission assembly 20. A filter plate 17 is assembled inside the dust hopper 15, with uniformly sized circular holes inside the filter plate 17. The filter plate 17 is funnel-shaped to facilitate the falling of silicon dust.
[0029] In the above embodiment, the ash hopper 15 is fixed to the lower end of the casing 10, the filter plate 17 is fixed to the upper end inside the ash hopper 15, the rotating part 16 is rotatably connected to the inside of the ash hopper 15 and located at the lower end of the filter plate 17, a crossbar 19 is fixed to the lower end inside the casing 10, and an arc-shaped plate 18 is rotatably connected to the outer side of the crossbar 19. One side of the arc-shaped plate 18 penetrates the filter plate 17 and extends into the inside of the ash hopper 15. When the rotating part 16 rotates, it can strike the arc-shaped plate 18. After being struck, the arc-shaped plate 18 can rotate around the crossbar 19 as the axis. When the arc-shaped plate 18 rotates, it will further impact the lower end of the filter plate 17. After being struck, the filter plate 17... The resulting vibrations cause the silica dust particles attached to its surface to fall off more quickly and slide down to the bottom of the ash hopper 15. In addition, when the arc plate 18 rotates clockwise, it will strike the filter plate 17, and the filter plate 17 will exert a reverse impact force on the arc plate 18. Under the action of the reverse impact force from the filter plate 17 to the arc plate 18 and the gravity of the arc plate 18 itself, the arc plate 18 begins to rotate in the opposite direction around the crossbar 19. At this time, the next blade of the rotating part 16 will continue to strike the arc plate 18, and the arc plate 18 will continue to strike the filter plate 17. This reciprocating vibration helps to shake off the dust on the filter bag of the bag filter. It should be noted that, in the initial state, one end of the arc plate 18 is tilted toward the inside of the ash hopper 15 under its own weight and the action of the crossbar 19. The arc plate 18 is located between the two blades on the outside of the rotating part 16. Under the reverse impact force of the filter plate 17 on the arc plate 18 and the action of the arc plate 18's own weight, the arc plate 18 can rotate in the opposite direction to the next two blades on the outside of the rotating part 16.
[0030] like Figure 2 and Figure 3 As shown, the transmission assembly 20 includes a bracket 21, a first rotating rod 22, a first gear 23, a second rotating rod 24, a second gear 25, a third gear 26, a third rotating rod 27, and a fourth gear 28. The bracket 21 is fixed to the lower end inside the housing 10. The first rotating rod 22 is rotatably connected to the lower end inside the bracket 21 and is fixedly connected to the output end of the motor 11. The first rotating rod 22 is also connected to the conveying assembly 30. The first gear 23 is fixed to the outside of the first rotating rod 22. The second rotating rod 24 is rotatably connected to the inside of the bracket 21. The second gear 25 is fixed to the lower end outside the bracket 21 and meshes with the first gear 23. The third gear 26 is fixed to the upper end outside the second rotating rod 24. The third rotating rod 27 is rotatably connected to the upper end inside the bracket 21 and is fixedly connected to the rotating part 16. The fourth gear 28 is fixed to the outside of the third rotating rod 27 and meshes with the third gear 26.
[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the conveying assembly 30 includes a screw conveyor 31 and a drive shaft 32. The screw conveyor 31 is fixed to the lower end inside the housing 10. A dust outlet is provided at the end of the screw conveyor 31 away from the motor 11. The drive shaft 32 is rotatably connected to the inside of the screw conveyor 31. The screw conveyor 31 and the first rotating rod 22 are fixedly connected, and the dust outlet and the drive shaft 32 are compatible. A detachable cover plate 33 is installed at the upper end of the screw conveyor 31 to facilitate internal maintenance by personnel.
[0032] like Figure 5 , Figure 6 and Figure 7 As shown, the dust hopper 15 is equipped with a filter plate 17. The filter plate 17 has uniformly sized round holes inside and is funnel-shaped to facilitate the falling of silicon dust.
[0033] Furthermore, the cross-sectional shape of the arc plate 18 is arc-shaped.
[0034] Furthermore, the exterior of the curved plate 18 is provided with a rubber layer for noise reduction.
[0035] The working principle of this utility model is as follows:
[0036] When the chassis 10 is started, the motor 11 begins to run. The operation of the motor 11 will drive the transmission assembly 20 to rotate. The bracket 21 is fixed to the lower end inside the chassis 10. The first rotating rod 22 is rotatably connected to the lower end inside the bracket 21. Therefore, when the output end of the motor 11 drives the first rotating rod 22 to rotate, since one side of the first rotating rod 22 is fixedly connected to the transmission shaft 32, the transmission shaft 32 also begins to rotate. The first gear 23 is fixed to the outer side of the first rotating rod 22. The first rotating rod 22 and the first gear 23 mesh, so the first gear 23 begins to rotate. Since the first gear 23 meshes with the second gear 25 and the second gear 25 is fixed to the outer side of the lower end of the second rotating rod 24, and the second rotating rod 24 is rotatably connected to the inside of the bracket 21, the second rotating rod 24 also begins to rotate. The third gear 26 is fixed to the outer side of the upper end of the second rotating rod 24. Therefore, the third gear 26 and the second rotating rod 24 rotate together. The fourth gear 28 meshes with the third gear 28, causing the fourth gear 28 to rotate. The fourth gear 28 is fixed to the outside of the third rotating rod 27, and the third rotating rod 27 is fixed to the upper end inside the bracket 21. Therefore, the third rotating rod 27 begins to rotate under the drive of the fourth gear 28. Since the third rotating rod 27 is fixedly connected to the rotating part 16, the rotating part 16 begins to rotate. During its counter-clockwise rotation, the rotating part 16 strikes the arc-shaped plate 18. The lower edge of the arc-shaped plate 18 is struck by the rotating part 16. The rotating center crossbar 19 begins to rotate clockwise. The filter plate 17 is fixed on the ash hopper 15. As the arc plate 18 rotates clockwise, it strikes the filter plate 17, generating vibration. The filter plate 17 exerts an impact force on the arc plate 18, causing the arc plate 18 to begin reciprocating motion. At this time, the next blade of the rotating part 16 will continue to strike the arc plate 18, and the arc plate 18 will continue to strike the filter plate 17. This reciprocating vibration helps to shake off the dust from the filter bags on the bag filter. When the output end of the motor 11 drives the first rotating rod 22 to rotate, the other side of the first rotating rod 22 drives the drive shaft 32 to rotate. The drive shaft 32 is rotatably connected to the inside of the screw conveyor 31. When the drive shaft 32 rotates, large dust particles fall from the ash hopper 15 into the inside of the screw conveyor 31 and are transported to the dust outlet under the action of the drive shaft 32. The conveying assembly 30 is also equipped with a removable cover plate 33 for easy internal inspection and cleaning maintenance by the staff.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
