Description

Technical Field

[0001] This utility model specifically relates to a device for preventing ash accumulation on insulators of electrostatic precipitators. Background Technology

[0002] In the recycled lead industry, the dust content of the flue gas at the inlet of electrostatic precipitators can reach over 100 grams per Nm3. The cathode rapping insulator connects the cathode rapping shaft and the reducer. When the electrostatic precipitator is running, the insulator is exposed to high dust levels in the flue gas, so dust easily accumulates on its surface, leading to insulator creep and breakdown, which affects the normal operation of the electrostatic precipitator. It is necessary to remove the dust from the insulator in a timely manner to ensure the normal operation of the electrostatic precipitator.

[0003] However, the existing electrostatic precipitator structure cannot remove the accumulated dust on the insulators. For example, the rapping structure of the electrostatic precipitator cannot remove the accumulated dust on the insulators. The dust generated after rapping will still adhere to the surface of the insulator. When the dust accumulation on the insulator is too thick and encounters condensed water vapor, the wet dust will still cause the insulation effect to be lost, which will lead to insulator creep and breakdown, affecting the normal operation of the electrostatic precipitator. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for preventing ash accumulation on insulators of electrostatic precipitators.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An anti-ash accumulation device for an electrostatic precipitator insulator includes a housing plate, a cover fixedly installed to the housing plate by bolts, a reducer fixedly installed at the tail of the cover by bolts, a vibrating shaft located inside the cover and connected to the output end of the reducer by a coupling, an insulator mounted on the vibrating shaft, and a jetting assembly fixed inside the cover and mounted on the insulator. The jetting assembly includes a spirally arranged tube, jetting holes opened inside the tube and facing the insulator, an air inlet pipe end bent upward from both ends of the tube, a connecting sleeve welded to the air inlet pipe end and penetrating the cover, a screw-on nut screwed onto the connecting sleeve and located outside the cover, an air supply pipe located outside the cover and fixedly connected to the connecting sleeve, and an air inlet pipe welded to the air supply pipe.

[0007] Preferably, there is a gap between the tube body and the inner wall of the casing.

[0008] Preferably, the blow holes are set at an angle.

[0009] Preferably, the blow holes are evenly distributed along the spiral line of the pipe body.

[0010] Preferably, two column base pipes are welded and connected to the air supply pipe, and a connecting nut is fitted at the lower end of the column base pipe.

[0011] Preferably, the air inlet pipe has air inlet ports at both ends.

[0012] Preferably, the top of the cover has two tube insertion holes.

[0013] The beneficial effects of this utility model are as follows: the spiral layout can expand the dust removal coverage area and avoid the dead angle problem of traditional straight-line blowing. The air pressure is balanced by the gradually narrowing orifice. The first air inlet pipe end and the second air inlet pipe end supply air at the same time to achieve the synergy of the two air inlet pipes, which enhances the airflow intensity and uniformity. In addition, the blowing assembly composed of the pipe body, blowing hole, air inlet pipe end, connecting sleeve, screw nut, air supply pipe and air inlet pipe works in coordination with the rapping shaft. That is, mechanical rapping is combined with airflow blowing to form a "dynamic and static" dust removal method, which ensures that the dust on the surface of the insulator is completely removed and prevents the insulator from creeping and breaking down.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Example

[0019] An anti-ash accumulation device for insulators of electrostatic precipitators, such as Figure 1-3 As shown, it includes a housing plate 1, a cover 2 fixedly installed to the housing plate 1 by bolts, a reducer 3 fixedly installed to the tail of the cover 2 by bolts, a vibrating shaft 4 located inside the cover 2 and connected to the output end of the reducer 3 by a coupling, an insulator 5 mounted on the vibrating shaft 4, and a jetting assembly 6 fixed inside the cover 2 and mounted on the insulator 5.

[0020] The top of the cover 2 has two tube insertion holes 21.

[0021] The blowing assembly 6 includes a spirally arranged tube 61, a blowing hole 62 opened inside the tube 61 and facing the insulator 5, an air inlet pipe end 63 bent upward from both ends of the tube 61, a connecting sleeve 64 welded to the air inlet pipe end 63 and penetrating the cover 2, a screw-on nut 65 screwed onto the connecting sleeve 64 and located outside the cover 2, an air supply pipe 66 located outside the cover 2 and fixedly connected to the connecting sleeve 65, and an air inlet pipe 67 welded to the air supply pipe 66.

[0022] It should be further explained that after the tube body 61 is placed inside the cover 2, the connecting sleeve 65 is passed through the tube body through hole 21 and screwed in the screw nut 65 so that the tube body 61 can be suspended inside the cover 2.

[0023] In this embodiment, there is a gap between the tube body 61 and the inner wall of the cover 2. Specifically, the gap between the tube body 61 and the inner wall of the cover 2 is designed to avoid contact between the tube body 61 and the cover 2, reduce dust blockage, extend the service life of the components, and prevent failures caused by friction or blockage.

[0024] In this embodiment, the blow hole 62 is inclined, which can blow the dust in one direction and improve the dust blowing and cleaning effect.

[0025] In this embodiment, the blow holes 62 are evenly distributed along the spiral line of the tube body 61. Specifically, the evenly spaced design of the blow holes 62 can balance the airflow distribution pressure.

[0026] Two column bases 661 are welded to the air supply duct 66, and a connecting nut 662 is fitted onto the lower end of the column bases 661. Specifically, the column bases 661 of the air supply duct 66 are aligned with the upper end of the connecting sleeve 65, and then the connecting nut 662 is screwed into the connecting sleeve 65 to fix the column bases 661, so that the air supply duct 66 is connected to the duct body 61.

[0027] The air inlet duct 67 has air inlet ports 671 at both ends. With the double-bent air inlet port 671 design, the air inlet duct 67 can simultaneously introduce pressurized and heated air, thereby achieving dual air inlet duct coordination through the air supply duct 67 and the air inlet ports 63 at both ends of the duct body 61, enhancing the airflow intensity and uniformity.

[0028] It should be further explained that the blowing assembly 6 works in conjunction with the rapping shaft, that is, mechanical rapping combined with airflow blowing, forming a "dynamic and static" dust removal method to ensure that the dust on the surface of the insulator is completely removed and to prevent insulator creep and breakdown.

[0029] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
