Description

Technical Field

[0001] This utility model relates to dust removal equipment technology, and more specifically, to dry electrostatic precipitators. Background Technology

[0002] A dry electrostatic precipitator is a highly efficient dust removal device. It consists of a housing, a dust hopper, and a power control cabinet. The housing is connected to an inlet pipe and an outlet pipe at both ends. Inside the housing, a filter, an electrode section, and a dust collection section are arranged sequentially. The filter removes larger dust particles from the air. The electrode section consists of several metal plates or rods carrying high voltage, creating a high-voltage electric field around it. This ionizes the air passing through the electrode section and charges the dust particles. The dust collection section consists of several dust collection plates, each carrying a low-voltage current and an opposite charge to that of the electrodes. This allows the charged dust particles to be attracted and adsorbed onto the dust collection plates, thus achieving dust removal.

[0003] When the dust collection plate has accumulated a large amount of dust, its adsorption effect on dust particles will decrease significantly. Therefore, it is necessary to clean and collect the dust on the dust collection plate regularly. The housing is usually equipped with a dust removal device. Most existing dust removal devices use mechanical vibration to shake the dust off the dust collection plate and into the ash hopper below. After cleaning, the dust collected in the ash hopper is cleaned. Since it is mechanical vibration dust removal, dust will be generated during the vibration process. This will cause the dust collection section to be filled with a certain amount of dust, which will have a certain impact on the filtration effect when the dry electrostatic precipitator is used.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dry electrostatic precipitator.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dry electrostatic precipitator, including a housing, an electrode plate and a dust collection plate are provided in the housing, a dust hopper is fixed on the housing and located directly below the dust collection plate, a scraper is slidably connected to the housing, the scraper has a perforation for the dust collection plate to pass through, a brush is provided on the inner peripheral wall of the perforation to abut against the outer peripheral wall of the dust collection plate, a driving component is provided on the housing to drive the scraper to make reciprocating linear motion on the dust collection plate, and a telescopic component is provided between the top surface of the scraper and the inner wall of the housing and arranged around the dust collection plate.

[0007] The present invention is further configured such that: the driving component is fixed on the outside of the housing, a rotating rod passing through the housing is provided below the driving component, a screw hole is provided on the scraper, and the rotating rod is threaded into the screw hole.

[0008] The present invention is further configured such that: a guide strip is provided in the vertical direction inside the box, and a guide groove for embedding the guide strip is provided on the side wall of the scraper.

[0009] The present invention is further configured such that: a cleaning component is provided on the side of the scraper facing the ash hopper, and the cleaning component is provided near the outer edge of the perforation.

[0010] The present invention is further configured such that: the number of perforations is two, and both perforations are located within the vertical projection plane of the telescopic member.

[0011] The present invention is further provided with a rubber strip on the scraper.

[0012] The present invention is further configured such that the rubber strip is annular.

[0013] In summary, this utility model has the following beneficial effects: When it is necessary to clean the dust on the dust collection plate, first seal the box and the air outlet pipe, start the drive to drive the scraper to move along the dust collection plate towards the ash hopper, so that the brush and the outer wall of the dust collection plate will rub against each other, so that the dust originally accumulated on the outer wall of the dust collection plate will be scraped off, thus completing the cleaning of the dust collection plate. As the scraper moves, the telescopic component originally clamped between the scraper and the inner wall of the box is stretched, so that the telescopic component is wrapped inside the dust collection plate cleaned by the brush, so that the dust caused by the brush scraping off the dust is not easy to drift between the cleaned dust collection plates. At the same time, the scraper moving towards the ash hopper can also push some of the dust into the ash hopper. When the scraper is in contact with the top surface of the ash hopper, people open the ash hopper and clean the dust in the ash hopper. At this time, the telescopic component wraps all the dust collection plates, which can effectively reduce the dust content in the dust collection plate area after cleaning, and reduce the impact of dust between the dust collection plates on the filtration effect of the dry electrostatic precipitator.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Dry electrostatic precipitators, such as Figure 1 and Figure 2 As shown, the device includes a housing 1, with an inlet pipe and an outlet pipe connected to both ends of the housing 1. An electrode plate 2 and a dust collection plate 3 are located inside the housing 1. The electrode plate 2 is positioned near the inlet pipe. A dust hopper 4 is fixed to the housing 1, located directly below the dust collection plate 3. A scraper 5 that slides up and down is provided on the housing 1. The scraper 5 has perforations 6 for the dust collection plate 3 to pass through. A brush 7 is provided on the inner wall of the perforations 6 to abut against the outer wall of the dust collection plate 3. The housing 1 is equipped with a mechanism for driving the scraper 5 to move the dust collection plate. The drive component 8 moves reciprocating linearly on the plate 3. A telescopic component 9, made of PU material, surrounds the side of the dust collection plate 3 between the top surface of the scraper 5 and the inner wall of the housing 1. During normal operation of the dry electrostatic precipitator, the scraper 5 is located at the end of the dust collection plate 3 furthest from the ash hopper 4, while the telescopic component 9 is clamped between the scraper 5 and the inner wall of the housing 1. The telescopic component 9 is used to seal the dust collection plate 3 between the top surface of the scraper 5 and the inner wall of the housing 1. When it is necessary to clean the dust on the dust collection plate 3... First, seal the space between the housing 1 and the outlet pipe. Then, activate the drive unit 8 to move the scraper 5 along the dust collection plate 3 towards the ash hopper 4. This causes the brush 7 to rub against the outer wall of the dust collection plate 3, scraping off the dust that was originally gathered on the outer wall of the dust collection plate 3, thus cleaning the dust collection plate 3. As the scraper 5 moves, the telescopic component 9, which was originally clamped between the scraper 5 and the inner wall of the housing 1, is stretched. This allows the telescopic component 9 to wrap around the dust collection plate 3 that has been cleaned by the brush 7, making it less likely for dust caused by the brush 7 to drift between the already cleaned dust collection plates 3. At the same time, the scraper 5 moving towards the ash hopper 4 can also push some of the dust into the ash hopper 4. When the scraper 5 is in contact with the top surface of the ash hopper 4, the ash hopper 4 is opened to clean the dust in it. At this time, the telescopic component 9 wraps around all the dust collection plates 3, which can effectively reduce the dust content in the area of ​​the dust collection plate 3 after cleaning and reduce the impact of dust between the dust collection plates 3 on the filtration effect of the dry electrostatic precipitator.

[0020] like Figures 1 to 3As shown, the drive component 8 is fixed to the outside of the housing 1. This arrangement ensures that dust inside the housing 1 will not affect the drive component 8, thus guaranteeing its service life. Below the drive component 8, a rotating rod 10 passes through the housing 1. A screw hole is provided on the scraper 5, and the rotating rod 10 is threaded into the screw hole. The screw hole is located on the two short sides of the scraper 5. The threaded transmission provides good stability, allowing the scraper 5, driven by the rotating rod 10, to slide smoothly along the dust collection plate 3. This enables the brush 7 to stably scrape the dust off the outer wall of the dust collection plate 3, thereby ensuring the scraper's performance. The cleaning effect of plate 5 on dust collection plate 3 is achieved by a guide strip 11 fixed vertically inside the housing 1. A guide groove 12 is provided on the side wall of scraper 5 for the guide strip 11 to be embedded in. The guide groove 12 is located on the two long sides of scraper 5. When the rotating rod 10 drives scraper 5 to move, the inner wall of the guide groove 12 abuts against the guide strip 11, allowing the guide strip 11 to provide good guidance for scraper 5 and further ensuring the stability of scraper 5's up-and-down sliding. A cleaning component 13 is provided on the side of scraper 5 facing the ash hopper 4. The cleaning component 13 is located near the outer edge of the perforation 6. Specifically, the cleaning component 13... Composed of several bristles surrounding the outer edge of the perforation 6, when the scraper 5 moves towards the ash hopper 4, the rotating rod 10 rotates and slides relative to the cleaning component 13, allowing the cleaning component 13 to promptly remove the dust adhering to the outer wall of the rotating rod 10. This also prevents wear caused by dust residue on the surface during relative friction between the inner wall of the screw hole and the outer wall of the rotating rod 10. There are two perforations 6, both located within the vertical projection plane of the telescopic component 9. This design allows the telescopic component 9 to enclose the rotating rod 10 after it has been cleaned by the cleaning component 13, preventing the scraped dust from re-adhering to the rotating rod. The rotating rod 10 can maintain its cleanliness. The scraper 5 is also provided with a rubber strip 14 on the same side as the cleaning component 13. The rubber strip 14 is ring-shaped. When the scraper 5 reaches the end near the ash hopper 4, the rubber strip 14 abuts against the top surface of the ash hopper 4. This arrangement allows the rubber strip 14 to separate the scraper 5 from the ash hopper 4, changing the original hard contact into a soft contact. At the same time, the ring-shaped rubber strip 14 can better seal the gap between the scraper 5 and the ash hopper 4, so that when people clean the dust in the ash hopper 4, the dust will not return to the box 1.
