Description
Technical Field
[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a baghouse dust collector with a filter anti-accumulation structure. Background Technology
[0002] Baghouse dust collectors are a common type of environmental protection equipment, mainly used to remove dust, particulate matter, and pollutants from gases. The bag filter can effectively filter dust and particles from the gas, and the filtered gas is discharged through an exhaust fan. However, existing baghouse dust collectors still have certain shortcomings in use.
[0003] In existing technologies, baghouse dust collectors are typically pulse-jet type. Baghouse dust collectors have advantages such as large air volume handling capacity, high dust removal efficiency, stable operation, simple operation, and convenient maintenance. Therefore, they are widely used in many industries, such as steel, power, chemical, food, and cement. After a certain period of use, the dust and particles adhering to the bag filter can be blown off by pulse jet cleaning. The dust and particles will fall into the conical ash hopper and the ash discharge pipe. Because the inner wall of the conical ash hopper is inclined, the dust and particles on the inner wall of the conical ash hopper are prone to accumulate and do not easily fall into the ash discharge pipe. Over time, this will make it difficult for the dust and particles on the inner wall of the conical ash hopper to be discharged. Utility Model Content
[0004] The purpose of this invention is to provide a bag filter dust collector with a filter anti-accumulation structure to solve the problem mentioned in the background art of dust accumulation on the inner wall of the conical ash hopper of current bag filters.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bag filter dust collector with a filter anti-accumulation structure, comprising: a housing, a conical ash hopper, an ash discharge pipe, an ash inlet pipe, a support frame, and a bag filter body. The bottom of the housing is connected to the conical ash hopper, the bottom of the conical ash hopper is connected to the ash discharge pipe, the outer side of the conical ash hopper is connected to the ash inlet pipe, the outer side of the housing is connected to the support frame, the bag filter body is installed inside the housing, an installation block is installed inside the housing, a triangular block is connected to the top of the installation block, a rotating rod is connected to the installation block via a bearing, a first scraper is connected to the outer side of the rotating rod near the conical ash hopper, a second scraper is connected to the outer side of the rotating rod near the ash discharge pipe, a guide rod is connected to the outer side of the rotating rod away from the second scraper, an annular groove is formed on the inner wall of the ash discharge pipe near the guide rod, a motor is installed on the outer side of the housing, the output end of the motor is connected to the housing via a rotating shaft via a bearing, and a belt is connected to both the rotating shaft and the rotating rod.
[0006] Preferably, the guide rod and the ash discharge pipe form a sliding structure through an annular groove.
[0007] Preferably, both the first scraper and the second scraper are made of plastic.
[0008] Preferably, a connecting block is welded between the two support frames, a threaded knob is threaded to the top of the connecting block, and a slide rod is slidably connected inside the connecting block.
[0009] Preferably, a support rod is connected to the bottom of the slide rod, and a mounting bracket is connected to the top of the slide rod, with a threaded rod internally threaded into the mounting bracket.
[0010] Preferably, the top end of the threaded rod is provided with a movable seat, and an arc-shaped support plate is welded to the top of the movable seat.
[0011] Preferably, a limiting rod is connected to the bottom of the arc-shaped support plate, and the limiting rod and the mounting frame form a sliding structure.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the motor runs, the bag filter with the anti-accumulation structure can drive the rotating shaft to rotate, and when the rotating shaft rotates, it can drive the belt to rotate, and when the belt rotates, it can drive the rotating rod to rotate. When the inner wall surface of the arc-shaped support plate moves to the bottom surface of the ventilation duct, the arc-shaped support plate can support the ventilation duct, making the ventilation duct less prone to loosening, thus eliminating the need for additional support devices. At the same time, it can ensure the stability of the connection between the ventilation duct and the ash inlet pipe, and the position of the arc-shaped support plate can be adjusted at any time according to the length of the ventilation duct.
[0013] 1. A bag filter is a highly efficient and stable dust filtration device. The bag filter body filters dust and particles from the gas, preventing them from being emitted to the outside. Since dust and particles on the bag filter body fall onto the inner wall of the conical hopper, they easily accumulate. When the motor runs, it drives a rotating shaft, which in turn drives a belt, which in turn drives a rotating rod. This rotating rod, in turn, drives a guide rod, which in turn drives the first and second scrapers. The first scraper scrapes away the dust and particles on the inner wall of the conical hopper. Before the first and second scrapers rotate, the ash discharge pipe can be opened to discharge the dust and particles from the inner walls of the conical hopper and the ash discharge pipe. The first scraper prevents dust and particles from accumulating on the inner wall of the conical hopper.
[0014] 2. During the use of the baghouse dust collector, the ventilation duct and the ash inlet pipe are connected to prevent loosening between them. When the support rod moves, it drives the sliding rod to slide through the connecting block. Simultaneously, the sliding rod moves the mounting bracket and the arc-shaped support plate. When a set of threaded holes inside the sliding rod moves directly below the threaded knob, the threaded knob can be tightened, allowing the end of the threaded knob to slide threadedly into the sliding rod, thus fixing its position. When the threaded rod rotates, it slides threadedly through the mounting bracket. Simultaneously, the top of the threaded rod rotates inside the moving seat, pushing the moving seat upwards. The movement of the moving seat drives the arc-shaped support plate. When the inner surface of the arc-shaped support plate moves to the bottom surface of the ventilation duct, it supports the ventilation duct, preventing it from loosening and eliminating the need for additional support devices. This ensures the stability of the connection between the ventilation duct and the ash inlet pipe, and the position of the arc-shaped support plate can be adjusted according to the length of the ventilation duct.

[0022] 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.
[0023] Please see Figures 1-4 It is understood that this utility model provides a technical solution: a bag filter dust collector with a filter anti-accumulation structure, comprising: a housing 1, a conical ash hopper 2, an ash discharge pipe 3, an ash inlet pipe 4, a support frame 5, and a bag filter body 6. The bottom of the housing 1 is connected to the conical ash hopper 2, the bottom of the conical ash hopper 2 is connected to the ash discharge pipe 3, the outside of the conical ash hopper 2 is connected to the ash inlet pipe 4, the outside of the housing 1 is connected to the support frame 5, the bag filter body 6 is installed inside the housing 1, an mounting block 7 is installed inside the housing 1, a triangular block 8 is connected to the top of the mounting block 7, and a rotating rod 9 is connected inside the mounting block 7 via a bearing. The moving rod 9 is connected to the outer side of the conical ash hopper 2 by a first scraper 10, the rotating rod 9 is connected to the outer side of the ash discharge pipe 3 by a second scraper 11, and the rotating rod 9 is connected to the outer side away from the second scraper 11 by a guide rod 12. The inner wall of the ash discharge pipe 3 near the guide rod 12 has an annular groove 13. A motor 14 is installed on the outer side of the housing 1. The output end of the motor 14 is connected to the housing 1 by a rotating shaft 15 through a bearing. The rotating shaft 15 and the rotating rod 9 are connected by a belt 16. The guide rod 12 and the ash discharge pipe 3 form a sliding structure through the annular groove 13. The first scraper 10 and the second scraper 11 are both made of plastic.
[0024] In practical implementation, the bag filter is a highly efficient and stable dust filtration device. The bag filter body 6 filters dust and particles in the gas, preventing them from being emitted to the outside. Since dust and particles on the bag filter body 6 fall onto the inner wall of the conical hopper 2, they easily accumulate there. Over time, this accumulation becomes difficult to remove. The motor 14 can be started. When the motor 14 runs, it drives the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 drives the belt 1... When belt 16 rotates, it drives rotating rod 9 to rotate. When rotating rod 9 rotates, it drives guide rod 12 to rotate. When guide rod 12 rotates, it can slide along annular groove 13. At the same time, rotating rod 9 can drive first scraper 10 and second scraper 11 to rotate. When first scraper 10 rotates, it can scrape the dust and particles on the inner wall of conical ash hopper 2. When second scraper 11 rotates, it can scrape the dust and particles on the inner wall of ash discharge pipe 3. Triangular block 8 can reduce the accumulation of dust and particles on mounting block 7.
[0025] See Figures 1-4 It can be seen that before the first scraper 10 and the second scraper 11 rotate, the ash discharge pipe 3 can be opened, so that the dust and particles on the inner wall of the conical ash hopper 2 and the ash discharge pipe 3 can be discharged. The first scraper 10 makes it difficult for dust and particles on the inner wall of the conical ash hopper 2 to accumulate.
[0026] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that a connecting block 17 is welded together between the two support frames 5. A threaded knob 18 is threadedly connected to the top of the connecting block 17. A slide rod 19 is slidably connected inside the connecting block 17. A support rod 20 is connected to the bottom of the slide rod 19. A mounting frame 21 is connected to the top of the slide rod 19. A threaded rod 22 is threadedly connected inside the mounting frame 21. A movable seat 23 is provided at the top of the threaded rod 22. An arc-shaped support plate 24 is welded to the top of the movable seat 23. A limit rod 25 is connected to the bottom of the arc-shaped support plate 24. A sliding structure is formed between the limit rod 25 and the mounting frame 21. A threaded hole is opened inside the slide rod 19.
[0027] In practical implementation, during the use of the bag filter dust collector, the ventilation duct is connected to the ash inlet pipe 4. The ventilation duct is not shown in the diagram. After the ventilation duct is installed, it usually requires an additional support device to support it and prevent loosening between the ventilation duct and the ash inlet pipe 4. Traditional support devices are relatively troublesome to install and are not easy to adjust in position. After one end of the ventilation duct is connected to the end of the ash inlet pipe 4, the support rod 20 can be pulled away from the support frame 5. When the support rod 20 moves, it can drive the sliding rod 19 to slide through the connecting block 17. At the same time, the sliding rod 19 can drive the mounting frame 21 and the arc-shaped support plate 2. 4. Move the slider 19. When a set of threaded holes inside the slider 19 moves directly below the threaded knob 18, tighten the threaded knob 18 so that the end of the threaded knob 18 can slide into the slider 19, thereby fixing the position of the slider 19. At this time, the threaded rod 22 can be rotated clockwise. When the threaded rod 22 rotates, it can slide through the mounting bracket 21. While the threaded rod 22 slides, its top end can rotate inside the movable seat 23 and push the movable seat 23 upward. When the movable seat 23 moves, it can drive the arc-shaped support plate 24 to move. When the arc-shaped support plate 24 moves, it can drive the limit rod 25 to move.
[0028] See Figure 1 , Figure 2 , Figure 5 and Figure 6It can be seen that when the inner wall surface of the arc-shaped support plate 24 moves to the bottom surface of the ventilation duct, the arc-shaped support plate 24 can support the ventilation duct, making the ventilation duct less prone to loosening, thus eliminating the need for additional support devices. At the same time, it can ensure the stability of the connection between the ventilation duct and the ash inlet pipe 4, and the position of the arc-shaped support plate 24 can be adjusted at any time according to the length of the ventilation duct.
[0029] In summary, when using this baghouse dust collector with a filter anti-accumulation structure, the motor 14 drives the rotating shaft 15 to rotate, which in turn drives the belt 16 to rotate, and the belt 16 to rotate the rotating rod 9. Before the first scraper 10 and the second scraper 11 rotate, the ash discharge pipe 3 can be opened, allowing dust and particles on the inner wall of the conical ash hopper 2 and the ash discharge pipe 3 to be discharged. The first scraper 10 prevents dust and particles on the inner wall of the conical ash hopper 2 from accumulating. When the inner wall surface of the arc-shaped support plate 24 moves to the bottom surface of the ventilation duct, the arc-shaped support plate 24 can support the ventilation duct, preventing it from becoming loose and eliminating the need for additional support devices. At the same time, it ensures the stability of the connection between the ventilation duct and the ash inlet pipe 4, and the position of the arc-shaped support plate 24 can be adjusted at any time according to the length of the ventilation duct.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
