Description

Technical Field

[0001] The utility model belongs to the technical field of dust cleaning equipment, and particularly relates to a dust cleaning device capable of preventing electron beam explosion and drilling. Background Art

[0002] Electron beam dust explosion is a violent explosion phenomenon caused by the interaction of an electron beam (a high-energy electron stream) with combustible dust in an environment where combustible dust exists. When the electron beam comes into contact with the combustible dust, it collides and excites the dust particles, generating a high-temperature and high-pressure reaction, resulting in a violent combustion and explosion of the dust cloud or dust. Electron beam dust explosions usually require two main conditions: the presence of combustible dust and the energy input of the electron beam. When there is a sufficient concentration of combustible dust, a fire source or ionization source, and the presence of oxygen, in some cases, the energy input of the electron beam can cause the combustible dust to spontaneously ignite and explode. This explosion can produce effects such as high temperature, high pressure, flames, and shock waves, which pose serious dangers to the surrounding environment and personnel. Therefore, in industrial environments involving combustible dust, especially when using electron beam processing or cleaning equipment, appropriate safety measures must be taken to prevent the occurrence of electron beam dust explosions.

[0003] Some existing dust cleaning devices may not be able to completely clean the combustible dust in the industrial environment. This may be due to the unreasonable design of the cleaning device, which cannot cover all dust accumulation areas, or improper operation of the cleaning device, resulting in some dust being missed or not effectively removed. Therefore, we hope to design a dust cleaning device with a new structure to solve this problem. Summary of the invention

[0030] The dust cleaning assembly 300 includes an air cylinder 310 and a solenoid valve 320. The air cylinder 310 is connected to the air pump outlet through an air supply pipe. The front and rear sides of the upper end of the air cylinder 310 are connected to a battery valve through a connecting pipe respectively.

[0031] See also Figures 1 to 4 The cleaning assembly 200 also includes an air inlet box 240, a dust hopper 250, a cleaning pipe 270 and a filter module 260. The air inlet box 240 is fixed to the rear side of the filter box 220. The lower part of the filter box 220 is connected to the inside of the air inlet box 240, and the air inlet box 240 is not directly connected to the upper part of the filter box 220.

[0032] A cleaning pipe 270 is installed at the rear side of the air inlet box 240. The cleaning pipe 270 includes a connection box 271 and a corrugated hose 272. One end of the corrugated hose 272 close to the air inlet box 240 is fixedly connected to the rear side of the connection box 271.

[0033] The front end of the connecting box 271 is fixedly connected to the rear side of the air inlet box 240 and the two are interconnected. A dust hood is provided at the end of the corrugated hose 272. The setting of the corrugated hose 272 allows the equipment to move the dust hood at will as needed, thereby cleaning the dust at various positions and reducing the residual amount in the cleaning dead corners.

[0034] A dust hopper 250 is welded at the lower end of the filter box 220, and a filter module 260 is installed inside the filter box 220. The filter module 260 includes a filter cartridge 261 and a mounting plate 262;

[0036] As the first embodiment of the utility model, in actual use, according to the actual position where dust needs to be cleaned, the corrugated hose 272 with the dust hood is moved to the designated position, and then the user turns on the fan 230. The drive of the fan 230 reduces the internal air pressure of the filter box 220, and then the air inside the air inlet box 240 is drawn into the filter cartridge 261 and then into the filter box 220. Subsequently, the air in the corrugated hose 272 is drawn into the air inlet box 240, and finally a negative pressure is generated at the position of the dust hood to clean the air at the designated position. By quickly cleaning the air at the designated position, the purpose of quickly removing the combustible dust at the position is achieved, thereby effectively preventing the electron beam from causing the combustible in the surrounding air to explode, thereby greatly improving the safety of the equipment.

[0039] As the second embodiment of the utility model, based on the above-mentioned first embodiment, in actual use, at regular intervals, the user can deliver compressed air to the inside of the air storage cylinder 310 through an external air pump, open the battery valve at the corresponding position as needed, and then the high-pressure and high-speed airflow inside the air storage cylinder 310 quickly enters the inside of the main air pipe 330 and sprays high-pressure and high-speed airflow through multiple back-blowing pipes 340 opposite to the filter cartridge 261, thereby achieving the purpose of back-blowing cleaning of the filter element inside. Under the action of the back-blowing pipes 340, the combustible dust intercepted in the filter element will be blown downward, and finally gradually fall into the ash hopper 250 for temporary storage under the action of its own gravity. The setting of the cleaning component 300 can effectively reduce the frequency of manual cleaning of the filter module 260, greatly reduce the labor intensity of the staff, and at the same time ensure that the equipment is always in a good filtering state, and can effectively and high-quality filter the combustible dust in the air, so as to protect the dust explosion caused by the dust contacting the electron beam in the purification environment.
