Description

Technical Field

[0001] This utility model belongs to the field of dust collector cleaning technology, specifically relating to a pulse jet cleaning device for electrostatic precipitators. Background Technology

[0002] Baghouse dust collectors filter dust-laden gas using filter materials, trapping dust particles on the surface of the filter bags to purify the air. The filter bags are made of woven fiber materials, such as polyester or glass fiber, which have good filtration effects and a certain mechanical strength. After a certain period of use, the filter bags of baghouse dust collectors need to be cleaned. In current technology, pulse jet cleaning devices are generally used for cleaning, and the dust removal effect is significant. However, there are often some shortcomings in actual use, so improvements are needed.

[0003] Chinese patent CN217795077U discloses a pulse jet cleaning device for a baghouse dust collector, comprising a support plate on which an electromagnetic pulse valve is mounted. The outlet of the electromagnetic pulse valve is connected to an airflow main pipe, which is a conical pipe with a specific taper. Branch pipes are evenly connected to the bottom of the airflow main pipe, and the branch pipes are a row of equal diameter pipes distributed at equal intervals on the side of the airflow main pipe. A movable flow guiding component is slidably fitted on the branch pipe. This utility model belongs to the field of dust collector cleaning technology, specifically referring to a pulse jet cleaning device for a baghouse dust collector that can make the gas flow rate ejected from each branch pipe equal, resulting in uniform pulse jet cleaning and thus improving the pulse cleaning effect.

[0004] However, although the above-mentioned technical solution can achieve the purpose of cleaning the dust inside the filter bag, in actual use, because the branch pipe sprays high-pressure gas vertically downwards, if the branch pipe descends and there is a certain distance between it and the top of the inner wall of the filter bag, the dust at the top of the inner wall of the filter bag will be difficult to clean, resulting in an insufficient cleaning effect on the filter bag. Over time, this can easily cause blockage and affect subsequent use, thus having certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a pulse jet cleaning device for electrostatic precipitators to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrostatic precipitator pulse jet cleaning device includes: a fixed plate, an electromagnetic pulse valve fixedly connected to the top of the fixed plate, a conical tube fixedly connected to the output end of the electromagnetic pulse valve, a plurality of sleeves fixedly connected to the bottom end of the surface of the conical tube, an extension tube slidably connected to the inner side wall of the sleeves, a rotating seat rotatably disposed at the bottom end of the surface of the extension tube, blades fixedly connected inside the rotating seat, an air inlet hood fixedly connected to the bottom end of the extension tube, an abutment block fixedly connected to the top of the rotating seat, a conical air guide hood slidably connected to the bottom end of the surface of the extension tube, a plurality of trapezoidal blocks fixedly connected to the bottom of the conical air guide hood, a plurality of first air outlet holes opened on the surface of the rotating seat, and a plurality of second air outlet holes opened at the bottom of the rotating seat.

[0011] Preferably, the input end of the electromagnetic pulse valve is fixedly connected to an air supply pipe, the surface of the extension pipe is provided with a sliding groove, and the conical air guide shroud slides inside the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When the bag filter is in use, the filter bag inside can be blown by the pulse jet cleaning device to separate the dust inside from the filter bag. At the same time, the dust at the top of the inner wall of the filter bag can also be guided by the high-pressure gas through the conical air guide hood, so that the dust on the inner wall of the filter bag can be cleaned, further improving the cleaning effect of the filter bag.

[0014] (2) The rotating seat and extension tube can be adjusted by electric telescopic rod to lower the distance, so that they can better blow the dust inside the filter bag. When blowing, the rotating seat rotates so that the gas is sprayed out through the first air outlet and blown towards the inner wall of the filter bag, thus improving the cleaning effect.

Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] Please refer to Figure 1 and Figure 2 As shown, an electric dust collector pulse jet cleaning device includes a fixed plate 1. The top of the fixed plate 1 is fixedly connected with an electromagnetic pulse valve 2. The output end of the electromagnetic pulse valve 2 is fixedly connected with a conical tube 3. The bottom end of the surface of the conical tube 3 is fixedly connected with a plurality of sleeves 4. The inner side wall of the sleeve 4 is slidably connected with an extension tube 5. The bottom end of the surface of the extension tube 5 is rotatably provided with a rotating seat 6. The inside of the rotating seat 6 is fixedly connected with a blade 7. The bottom end of the extension tube 5 is fixedly connected with an air inlet hood 8. The top of the rotating seat 6 is fixedly connected with a contact block 9. The bottom end of the surface of the extension tube 5 is slidably connected with a conical air guiding hood 10. The bottom of the conical air guiding hood 10 is fixedly connected with a plurality of trapezoidal blocks 11. A plurality of first air outlet holes 12 are opened on the surface of the rotating seat 6. A plurality of second air outlet holes 13 are opened at the bottom of the rotating seat 6.

[0022] Through the setting of the conical tube 3, the gas entering its interior through the electromagnetic pulse valve 2 can enter the interior of the sleeve 4 evenly. The conical tube 3 adopts a conical design with a contraction angle of five to eight degrees, causing the gas flow rate to decrease along the way, compensating for the static pressure change, and reducing the flow deviation from 25% to within 5%. Through the setting of the extension tube 5, the rotating seat 6 can be rotatably arranged at the bottom end of its surface. The gas is sprayed onto the blade 7 through the extension tube 5, causing the rotating seat 6 to rotate, thereby causing the抵触块9 (it seems there is a typo here, maybe it should be a specific component name) to rotate, and finally causing the抵触块9 to push the trapezoidal block 11, causing the conical air guide cover 10 to move up and down, changing the direction of gas flow, and enabling the dust on the top position of the inner wall of the dust removal cloth bag to be blown. It should be noted that air outlet holes are also provided at the position on the surface of the extension tube 5 covered by the conical air guide cover 10 at the bottom end, facilitating the discharge of gas, and enabling it to be discharged through the conical air guide cover 10. Through the opening of the first air outlet hole 12 and the second air outlet hole 13, high-pressure gas can be blown onto the dust removal cloth bag.

[0023] The input end of the electromagnetic pulse valve 2 is fixedly connected to a gas supply pipe 17. A sliding groove is provided on the surface of the extension tube 5, and the conical air guide cover 10 is located inside the sliding groove and slides. Through the setting of the gas supply pipe 17, the high-pressure gas generated by the high-pressure pulse generating device can be blown into the interior of the electromagnetic pulse valve 2 and finally enter the interior of the conical tube 3. The sliding groove facilitates the up and down sliding of the conical air guide cover 10.

[0024] Embodiment 2:

[0025] Please refer to Figure 1 and Figure 3 As shown, an electric telescopic rod 18 is fixedly connected inside the fixing plate 1, and a linkage rod 14 is arranged below the fixing plate 1.

[0026] A connecting block 15 is fixedly connected to one side of the surface of the linkage rod 14, and the output end of the electric telescopic rod 18 is fixedly connected to the top of the connecting block 15. Through the setting of the electric telescopic rod 18, it can带动衔接块15下降 (it seems there is a typo here, maybe it should be a more accurate description like "cause the connecting block 15 to descend"), and then cause the linkage rod 14 to descend, thereby adjusting the position of the extension tube 5 inside the dust removal cloth bag.

[0027] A connecting rod 16 is fixedly connected to the top end of the surface of the extension tube 5, and the other end of the connecting rod 16 is fixedly connected to the top end of the surface of another extension tube 5. Through the setting of the connecting rod 16, several extension tubes 5 can move up and down simultaneously.

[0028] The working principle of this utility model is as follows: The operator first opens the high-pressure pulse generator, allowing high-pressure gas to enter the electromagnetic pulse valve 2 through the gas supply pipe 17, and then enters the conical tube 3. Inside the conical tube 3, the gas passes through the sleeve 4 and enters the extension tube 5. Part of the gas then exits through the air outlet inside the extension tube 5 into the conical air guide shroud 10, while another part flows downwards through the extension tube 5 and is blown onto the blades 7. A further portion of the gas is discharged through the first air outlet 12 and the second air outlet 13, blowing onto the dust collector bag, thus facilitating the dust collection. The bag vibrates at high frequency, causing the dust to fall off. When the blade 7 rotates, it drives the rotating seat 6 to rotate, which in turn causes the contact block 9 to continuously push up the trapezoidal block 11. When the top of the contact block 9 slides to the inclined position of the trapezoidal block 11, it continuously moves to the right, causing the conical air guide hood 10 to be continuously pushed up and down. This allows the conical air guide hood 10 to discharge the gas to the top of the inner wall of the dust collector bag, improving the dust removal effect. The operator can also control the electric telescopic rod 18 to drive the linkage rod 14 to descend, so that the position of the conical air guide hood 10 can be adjusted, further improving the dust removal efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
