Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and more specifically, to a high-efficiency electrostatic dust collector. Background Technology

[0002] An electrostatic precipitator is a device used for air purification. It primarily uses electrostatic force to remove fine particulate matter (such as dust, smoke, and particulate matter) from the airflow. It is widely used in industrial fields, especially in flue gas emissions and air pollution control, to reduce harmful particulate matter emissions and protect the environment. Particles are attracted by an electric current and move towards another electrode (usually a collecting electrode). The collecting electrode is typically a positively charged surface, creating an electric field that attracts charged particles to its surface.

[0003] However, most high-efficiency electrostatic precipitators currently have the following problems:

[0004] For example, the wet electrostatic precipitator with publication number 202320272199.8, although it can clean the dust on the electrode plates by spraying water through the spray head, will change the original resistance distribution of the electrode plates after they get wet, resulting in inaccurate or failed signal transmission, affecting the dust removal effect. Moreover, the gas after dust removal is often quite humid, and the discharged humid gas can easily affect the surrounding environment, making it inconvenient to clean the dust and remove moisture. At the same time, the moisture-proof electrostatic precipitator with publication number 202322055615.1, although it can transport and remove dust through the air inlet pipe, cannot control the airflow speed. If the airflow is too fast, it is easy for the airflow to not be dehumidified. In addition, the high speed means that the airflow stays between the cathode plate and the anode plate for a short time, and cannot be electrostatically adsorbed for dust, resulting in poor dust removal effect and inconvenience in adjusting and controlling the airflow speed.

[0005] Therefore, we have made improvements to this and proposed a high-efficiency electrostatic precipitator. Utility Model Content

[0006] The purpose of this invention is to address the current problems of inconvenient dust and moisture removal, and the inconvenience of adjusting and controlling airflow speed.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] High-efficiency electrostatic precipitators are used to improve the above problems.

[0009] The application is as follows:

[0010] The system includes a conveying pipe, a connecting shaft connected to a sealed bearing on the conveying pipe, a baffle fixedly connected to the connecting shaft, a rotating shell fixedly connected to the connecting shaft, a first spring fixedly connected inside the rotating shell, a limit plate fixedly connected to the other end of the first spring, a Velcro fastener fixedly connected to the limit plate and the conveying pipe, a connecting frame fixedly connected to the limit plate, a housing fixedly connected to the conveying pipe, a mesh box disposed inside the housing, a limit block fixedly connected to the mesh box, dehumidifying particles disposed inside the mesh box, a cover plate disposed on the housing, a filter plate fixedly connected to the cover plate, an activated carbon plate fixedly connected to the cover plate, a dust collection electrode plate fixedly connected to the cover plate, a collection box fixedly connected to the housing, a sealing cover bolted to the collection box, a fixing plate fixedly connected inside the housing, and a dust removal scraper fixedly connected to the fixing plate.

[0011] As a preferred technical solution of this application, the connecting shaft is fixedly connected to the center of the baffle and the rotating shell. The width of the baffle is smaller than the width of the conveying pipe. The side end face of the limiting plate is in contact with the inner side of the rotating shell. The first spring is distributed at equal angles on the limiting plate.

[0012] As a preferred technical solution of this application, the top surface of the mesh cage is attached to the inner top surface of the cover plate, the side surfaces of the filter plate and activated carbon plate are attached to the inner side surface of the shell, and the dust collection electrode plates are evenly distributed on the cover plate.

[0013] As a preferred technical solution of this application, the housing and the cover are provided with a limiting frame, a card box is fixedly connected to the limiting frame, a second spring is fixedly connected inside the card box, and the dust removal scrapers are evenly distributed on the fixed plate.

[0014] As a preferred technical solution of this application, a connecting plate is fixedly connected to the other end of the second spring, a locking block is fixedly connected to the connecting plate, a pressing plate is fixedly connected to the connecting plate, and the side end face of the connecting plate is in contact with the inner side of the card box.

[0015] As a preferred technical solution of this application, the second spring is symmetrically distributed on the upper and lower sides of the card box, and the second spring corresponds to the card block one by one through the connecting plate. The length of the card block is less than the length of the groove in the card box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. Equipped with a cover plate; during dust removal, the gas passing through the mesh box can be adsorbed and dehumidified by the internal dehumidifying particles. Combined with multiple evenly distributed dust collecting electrode plates, electrostatic dust removal is achieved. Under the action of the filter plate and activated carbon plate, multi-stage filtration is possible, improving the filtration effect. During disassembly and cleaning, the squeezing plate on the card box can be squeezed, which drives the connecting plate to move within the card box. The connecting plate squeezes the second spring, causing the connecting plate to detach from the limiting frame, housing, and cover plate, and retract into the card box. The limiting frame and card box can be removed from the housing and cover plate for disassembly, allowing the cover plate to be disassembled and the activated carbon plate and dust collecting electrode plates removed for cleaning. The dust collecting electrode plates on the cover plate can also be removed from the dust removal scraper, which scrapes away dust for early cleaning, preventing interference with the cleaning effect of gaps. The mesh box can be unobstructed for replacing the dehumidifying particles, improving the cleaning and installation effect.

[0019] 2. Equipped with a baffle; when adjusting the wind speed, the connecting frame can be pulled to move the limiting plate. The limiting plate can compress the first spring, and at the same time, the Velcro on the limiting plate can detach from the Velcro on the conveying pipe. After being unobstructed, the rotating shell can be rotated to drive the connecting shaft to rotate. When the connecting shaft drives the baffle to rotate, the tilt angle of the baffle can be adjusted. The wind speed can be adjusted under the baffle's blocking effect for control and regulation.

[0035] Example 1:

[0036] like Figure 1-9 As shown, this embodiment proposes a high-efficiency electrostatic precipitator, including a conveying pipe 1, a connecting shaft 2 connected to the conveying pipe 1 by a sealed bearing, a baffle 3 fixedly connected to the connecting shaft 2, a rotating shell 4 fixedly connected to the connecting shaft 2, a first spring 5 fixedly connected inside the rotating shell 4, a limiting plate 6 fixedly connected to the other end of the first spring 5, a Velcro 7 fixedly connected to the limiting plate 6 and the conveying pipe 1, a connecting frame 8 fixedly connected to the limiting plate 6, a housing 9 fixedly connected to the conveying pipe 1, and a mesh disposed inside the housing 9. Box 10, with a limiting block 11 fixedly connected to it, and dehumidifying particles 12 inside the box 10. Cover plate 13 is provided on the shell 9, with filter plate 14 fixedly connected to cover plate 13, activated carbon plate 15 fixedly connected to cover plate 13, and dust collection electrode plate 16 fixedly connected to cover plate 13. Collection box 17 is fixedly connected to the shell 9, with sealing cover 18 bolted to collection box 17. Fixing plate 19 is fixedly connected inside the shell 9, with dust removal scraper 20 fixedly connected to fixing plate 19.

[0037] Example 2:

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, the connecting shaft 2 is further fixedly connected to the center of the baffle 3 and the rotating shell 4. The width of the baffle 3 is smaller than the inner width of the conveying pipe 1. The side end face of the limiting plate 6 is in contact with the inner side of the rotating shell 4. The first spring 5 is distributed at equal angles on the limiting plate 6, which can ensure that when the rotating shell 4 rotates, the connecting shaft 2 can smoothly drive the baffle 3 to rotate and adjust the angle.

[0040] like Figure 6 As shown, in a preferred embodiment, based on the above method, the top surface of the mesh box 10 is attached to the inner top surface of the cover plate 13, the side surfaces of the filter plate 14 and the activated carbon plate 15 are attached to the inner surface of the shell 9, the dust collection electrode plates 16 are equidistantly distributed on the cover plate 13, the shell 9 and the cover plate 13 are provided with a limiting frame 21, a card box 22 is fixedly connected to the limiting frame 21, a second spring 23 is fixedly connected inside the card box 22, and the dust removal scrapers 20 are equidistantly distributed on the fixing plate 19, which can ensure that multiple dust removal scrapers 20 can clean the dust on the corresponding dust collection electrode plates 16.

[0041] like Figure 9As shown, in a preferred embodiment, based on the above method, the other end of the second spring 23 is further fixedly connected to a connecting plate 24, a locking block 25 is fixedly connected to the connecting plate 24, and a pressing plate 26 is fixedly connected to the connecting plate 24. The side end face of the connecting plate 24 is in contact with the inner side of the card box 22. The second spring 23 is symmetrically distributed on the upper and lower sides inside the card box 22. The second spring 23 corresponds one-to-one with the locking block 25 through the connecting plate 24. The length of the locking block 25 is less than the length of the groove inside the card box 22, which can ensure that the locking block 25 can be retracted into the card box 22 for disengagement.

[0042] Specifically, when using this high-efficiency electrostatic precipitator: (in conjunction with...) Figure 1-9 When adjusting the wind speed, the connecting frame 8 can be pulled to move the limiting plate 6. The limiting plate 6 can compress the first spring 5, and at the same time, the Velcro 7 on the limiting plate 6 can detach from the Velcro 7 on the conveying pipe 1. After being unobstructed, the rotating shell 4 can be rotated to drive the connecting shaft 2 to rotate. When the connecting shaft 2 drives the baffle 3 to rotate, the tilt angle of the baffle 3 can be adjusted. The wind speed can be adjusted under the blocking of the baffle 3 for control and adjustment. After the adjustment is completed, the connecting frame 8 is released, and the limiting plate 6 is reset under the push of the first spring 5. The Velcro 7 on the limiting plate 6 is stuck to the Velcro 7 on the conveying pipe 1 for fixed positioning, which can fix the use angle of the baffle 3.

[0043] When the conveying pipe 1 delivers air, the gas passing through the mesh box 10 is dehumidified by the internal desiccant particles 12. Combined with multiple evenly distributed dust-collecting electrode plates 16, electrostatic dust removal is achieved. Under the action of the filter plate 14 and activated carbon plate 15, multi-stage filtration is performed. The filter plate 14 cleans the residue in the gas, and the activated carbon plate 15 purifies the air, improving the filtration effect. Furthermore, during disassembly and cleaning, the compression plate 26 on the card box 22 can be squeezed, which in turn drives the connecting plate 24. Moving within the card box 22, the connecting plate 24 presses against the second spring 23, causing the connecting plate 24 to drive the card block 25 to detach from the limiting frame 21, the housing 9, and the cover plate 13, and retract into the card box 22. The limiting frame 21 and the card box 22 can then be removed from the housing 9 and the cover plate 13 for disassembly, allowing the cover plate 13 to be separated. The activated carbon plate 15 and the dust collecting electrode plate 16 on the cover plate 13 can then be removed for cleaning. Furthermore, the dust collecting electrode plate 16 on the cover plate 13 is removed from the dust removal scraper 20. Multiple dust removal scrapers 20 on the fixed plate 19 can scrape off dust for early cleaning. After disassembly, they can be used for detailed cleaning, avoiding the inability to clean narrow gaps completely. The scraped dust can fall into the collection box 17 for centralized collection. When cleaning is needed later, the sealing cover 18 on the collection box 17 can be removed to collect and clean the dust, avoiding affecting the cleaning effect of gaps. The mesh box 10 can be replaced without obstruction to clean the dehumidifying particles 12, improving the cleaning and installation effect. When installing the reset cover plate 13, the cover plate 13 is installed and reset on the housing 9. The card box 22 on the limit frame 21 is inserted into the housing 9 and the cover plate 13. The pressing plate 26 is released, and under the push of the second spring 23, the connecting plate 24 and the card block 25 are reset. The card block 25 is locked in the housing 9 and the cover plate 13 for fixed positioning, which can improve the fixed stability and save time and effort in disassembly and installation. The limiting block 11 on the mesh box 10 is locked in the housing 9, which can play a limiting role and prevent shaking during filtration.

[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
