[0002] With the development of modern industry, baghouse dust collectors are used in industries such as steel, chemicals, and cement to efficiently remove dust and exhaust gases, meeting environmental protection requirements. During long-term operation, as dust accumulates on the filter bags, a pulse-jet cleaning system is needed to prevent clogging. However, this system requires a large amount of compressed air. In cold regions where temperatures drop below 0 degrees Celsius, the air condenses and freezes, causing blockages in the system. Prolonged exposure to extremely low temperatures can also damage the electromagnetic pulse valve housing, internal diaphragms, and other components, affecting their service life. Therefore, a pulse-jet cleaning protection device is urgently needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a pulse jet cleaning protection device, which uses the heat preservation box body to heat and electrically heat the electromagnetic pulse valve in the pulse jet cleaning component, so that the compressed air in the jet air circuit does not freeze or condense, thus ensuring the normal operation and service life of the electromagnetic pulse valve.

[0004] To achieve the above objectives, this utility model provides a pulse jet cleaning protection device, including an insulated box body and a pulse jet cleaning assembly fixed inside the insulated box body. The bottom of the pulse jet cleaning assembly is provided with several fixed flanges at equal intervals. The pulse jet cleaning assembly includes an air tank, an electromagnetic pulse valve, and an air distribution pipe. One end of the air distribution pipe is connected to the electromagnetic pulse valve, and the other end of the air distribution pipe passes through the bottom of the insulated box body and is connected to the fixed flanges. The inner wall of the insulated box body is fixedly connected to the air tank.

[0005] Preferably, the gas storage tank has an air inlet for filling high-pressure gas on one side, and a manual drain valve is provided on the bottom of the gas storage tank away from the air inlet.

[0006] Preferably, the electromagnetic pulse valve is fixedly installed on the top of the gas storage tank, and the number of electromagnetic pulse valves is the same as the number of fixed flanges.

[0007] Preferably, the insulated box body includes an insulation board, and the inner wall of the insulated box body is provided with a heating cable for heating. Several heating cables are snapped and fixed to the inner wall of the insulated box body through slots. An electric heating terminal is provided on one side of the insulated box body, and the heating cable is electrically connected to the electric heating terminal.

[0008] Preferably, the top of the insulated box body is provided with a top plate, and the top plate is movably connected to one side of the insulated box body by a hinge.

[0009] Preferably, the insulation board and the top plate are filled with aluminum silicate insulation cotton, and the thickness of the aluminum silicate insulation cotton is not less than 50mm.

[0010] Preferably, a temperature sensor is provided at the upper end of the insulation box body, and the temperature sensor and the electric heating terminal are electrically connected to the external control cabinet in sequence, so that the temperature inside the insulation box body can be displayed and adjusted on the PLC in the external control cabinet.

[0011] Therefore, the pulse jet cleaning and protection device of this utility model, which adopts the above-described structure, has the following advantages compared with the prior art: (1) In this utility model, aluminum silicate insulation cotton is filled into the body of the insulation box to facilitate the insulation of the electromagnetic pulse valve in the jet cleaning component, ensuring the normal operation and service life of the pulse valve. At the same time, the top plate on the body of the insulation box is easy to disassemble and install, making it convenient to inspect the jet cleaning component inside the box.

[0012] (2) In this utility model, the temperature inside the heat preservation box is detected by a temperature sensor. When the temperature inside the box is lower than the set temperature, the heat tracing cable is powered on and heated by the PLC. The heat tracing cable is ring-shaped and layered and attached to the inner wall of the heat preservation box body, which effectively improves the heating uniformity and heating effect inside the heat preservation box body, so that the ambient temperature around the spray cleaning component is not lower than 5 degrees Celsius, and ensures that the spray air path of the electromagnetic pulse valve does not freeze or condense.

[0017] Example like Figures 1-2 As shown, Figure 1 This is a schematic diagram of the overall structure of an embodiment of the pulse jet cleaning and protection device of this utility model. Figure 2 This is a front view of an embodiment of the pulse jet cleaning and protection device of this utility model. It includes an insulated box body 1 and a pulse jet cleaning assembly 2 fixed inside the insulated box body 1. Several fixed flanges 3 are equidistantly arranged at the bottom of the pulse jet cleaning assembly 2. The pulse jet cleaning assembly 2 includes an air tank 22, an electromagnetic pulse valve 21, and an air distribution pipe 23. One end of the air distribution pipe 23 is connected to the electromagnetic pulse valve 21. An air inlet 4 for filling with high-pressure gas is provided on one side of the air tank 22. A manual drain valve 5 is provided on the bottom of the air tank 22 away from the air inlet 4 for manually draining moisture from the air tank 22. Figure 4 As shown, the other end of the gas distribution pipe 23 passes through the bottom of the insulation box body 1 and is connected to the fixed flange 3. The electromagnetic pulse valve 21 is fixedly installed on the top of the gas storage tank 22, ensuring that the number of electromagnetic pulse valves 21 is the same as the number of fixed flanges 3. The inner wall of the insulation box body 1 is fixedly connected to the gas storage tank 22.

[0018] like Figure 3As shown, the insulation box body 1 includes an insulation board. The inner wall of the insulation box body 1 is provided with heating cables 6. Several heating cables 6 are fixed to the inner wall of the insulation box body 1 via slots 7. During installation, the heating cables 6 are arranged in a ring-shaped, layered manner on the inner wall of the insulation box body 1, effectively improving the heating uniformity and heating effect inside the insulation box body 1. This ensures that the ambient temperature around the jet cleaning assembly 2 is not lower than 5 degrees Celsius, preventing ice formation and condensation in the jet air path of the electromagnetic pulse valve 21. An electric heating terminal 8 is provided on one side of the insulation box body 1, and the heating cables 6 are electrically connected to the electric heating terminal 8. A top plate 9 is provided on the top of the insulation box body 1, and the top plate 9 is movably connected to one side of the insulation box body 1 via a hinge. The insulation board and top plate 9 are filled with aluminum silicate insulation cotton 11. The thickness of aluminum silicate insulation cotton 11 is not less than 50mm, and the thickness of aluminum silicate insulation cotton 11 can be appropriately increased according to the temperature of the area where it is used. The aluminum silicate insulation cotton 11 is filled inside the insulation box body 1 to facilitate the insulation of the electromagnetic pulse valve 21 in the jet cleaning assembly 2, ensuring the normal operation and service life of the pulse valve. At the same time, the top plate 9 on the insulation box body 1 is easy to disassemble and assemble, making it convenient to inspect and maintain the jet cleaning assembly 2 inside the box.

[0019] A temperature sensor 10 is installed at the upper end of the insulation box body 1. The temperature sensor 10 and the electric heating terminal 8 are electrically connected to the external control cabinet in sequence, so that the temperature inside the insulation box body 1 can be displayed and adjusted on the PLC in the external control cabinet. The temperature inside the insulation box body 1 is detected by the temperature sensor 10. When the temperature inside the box is lower than the set temperature, the PLC controls the heating tape 6 to be powered on for heating.

[0020] Therefore, in this invention, the electromagnetic pulse valve in the jet cleaning assembly is insulated and electrically heated by the heat preservation box body, so that the compressed air in the jet cleaning air path in the air storage tank does not freeze or condense, thus ensuring the normal operation and service life of the electromagnetic pulse valve.
