Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a welding smoke exhaust and dust removal filtering system. Background Art

[0002] The smoke exhaust and dust removal filtration system is a complete set of equipment that discharges and filters the dusty smoke generated during the drying and mixing process. It is composed of a dust-generating equipment hood, an exhaust hood, an exhaust duct, a dust collector, a ventilator, an exhaust duct (including a chimney), duct accessories, dust exhaust equipment, and maintenance and monitoring facilities. When assembling some parts or devices, welding function is required, and smoke will be generated during the welding process. The welding smoke is mainly composed of tiny particles generated by metal melting, oxidation, and incomplete combustion of gas during the welding process. These particles may contain metal oxides, ammonia oxides, carbon monoxide and other harmful substances. Therefore, a smoke exhaust and dust removal filtration system is needed for filtration.

[0003] Although the dry filtration method in the current smoke exhaust and dust removal filtration system uses filter products such as filter cotton and activated carbon, the filtration effect is still not ideal when dealing with fine dust in the flue gas. The main reasons are as follows:

[0004] First of all, the dry filtration method mainly relies on the principle of physical isolation to capture particulate matter in the air through the adsorption of filter cotton and activated carbon. However, for extremely small dust particles or particles smaller than the pores of the filter medium, they may pass through the filter layer directly without being captured, resulting in a decrease in the filtration effect.

[0005] Although activated carbon has strong adsorption capacity, its adsorption effect is affected by different factors such as particle size, shape and ambient humidity. For fine dust particles, due to their light weight, large surface area and easy suspension in the air, the adsorption effect of activated carbon may not be significant enough to completely remove these particles.

[0006] Therefore, it is necessary to design a welding fume exhaust and dust removal filtration system. Utility Model Content

[0007] In order to overcome the shortcoming that the filtering effect is not significant enough, the utility model provides a welding smoke exhaust dust removal filtering system.

[0008] A welding smoke exhaust dust filtration system includes an exhaust pipe, a protective plate, a clamping rod, an exhaust fan, a fixing frame, filter cotton, an adsorption frame, activated carbon, a connecting frame, screws, a first isolation frame, a sprayer, a connecting frame and a fan. The protective plate is arranged at the front side of the exhaust pipe through the clamping rod, the sides of the exhaust pipe are connected to the exhaust pipe, the exhaust fans are arranged inside the exhaust pipe, the fixing frame is arranged inside the exhaust pipe, the filter cotton is arranged at the lower part of the fixing frame, the adsorption frame is symmetrically arranged inside the fixing frame, the activated carbon is arranged at the upper part of the fixing frame, the connecting frame is symmetrically arranged on the exhaust pipe, the screws are arranged on the connecting frame, the first isolation frame is symmetrically arranged in the middle part of the exhaust pipe, the sprayers are arranged in the first isolation frame, the connecting frame is arranged on the exhaust pipe, and the fan is arranged in the connecting frame.

[0009] Preferably, a second isolation frame is further included, the first isolation frame is designed as a semi-enclosed structure, and the second isolation frame is arranged on the front side of the first isolation frame by bolts.

[0010] Preferably, it further comprises a collecting frame and a fixing member, and the collecting frame is arranged at the bottom of the discharge pipe through the fixing member.

[0011] Preferably, a handle is further included, and the handle is arranged on the side of the fixing member.

[0012] Preferably, at least three filter cottons are provided.

[0013] Preferably, at least two adsorption racks are provided.

[0014] The beneficial effects and significant improvements of the utility model are:

[0015] The utility model uses filter cotton and adsorption frame combined with activated carbon to achieve efficient dry filtration, effectively removing dust and harmful substances in the flue gas. At the same time, the sprayer humidifies the flue gas, enhances the wet filtration effect, and makes the filtration more thorough. This double filtration method significantly improves the filtration effect and makes the flue gas cleaner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] Embodiment: A welding fume exhaust dust removal filtration system, such as Figures 1 to 7 , including a discharge pipe 1, a protective plate 101, a clamping rod 102, an exhaust fan 2, a fixing frame 3, filter cotton 4, an adsorption frame 5, activated carbon 6, a connecting frame 7, a screw 8, a first isolation frame 9, a sprayer 10, a second isolation frame 11, a collecting frame 12, a fixing piece 13, a handle 14, a connecting frame 15 and a fan 16. A protective plate 101 is installed on the front side of the discharge pipe 1 through the clamping rod 102. The left and right sides of the lower part of the discharge pipe 1 are connected with an inverted "L"-shaped exhaust pipe. The exhaust fan 2 is installed inside the exhaust pipe. The inner middle part of the discharge pipe 1 is longitudinally connected with a fixing frame 3. Filter cotton 4 is arranged at the lower part of the fixing frame 3. At least three filter cottons 4 are arranged to achieve a better filtering effect. Adsorption frames 5 are symmetrically arranged inside the fixing frame 3. At least two adsorption frames 5 are arranged to achieve a better filtering effect. The adsorption frame 5 is located above the filter cotton 4. Activated carbon 6, connecting frames 7 are connected to the left and right sides of the upper and middle parts of the discharge pipe 1, screws 8 are installed on the connecting frames 7, first isolation frames 9 are connected to the left and right sides of the middle part of the discharge pipe 1, sprayers 10 are installed in the first isolation frames 9, the water inlet pipe at the lower end of the sprayer 10 runs through the bottom of the first isolation frame 9, and the water outlet pipe of the sprayer 10 runs through the left side of the discharge pipe 1, the first isolation frame 9 is a semi-wrapped structure design, and a second isolation frame 11 is installed on the front side of the first isolation frame 9 by bolts to facilitate the subsequent maintenance of the sprayer 10, a collecting frame 12 is installed at the bottom of the discharge pipe 1 through a fixing 13, and the collecting frame 12 is used to collect the substances precipitated inside the discharge pipe 1, a handle 14 is connected to the side of the fixing 13 to facilitate the removal of the fixing 13, and a connecting frame 15 is connected to the top of the discharge pipe 1, and a fan 16 is installed in the connecting frame 15 to accelerate the circulation of flue gas.

[0025] The welding smoke exhaust dust removal filtration system is installed at the designated working position by using the connecting frame 7 and the screws 8, the external water pipe is connected to the water inlet pipe of the sprayer 10 itself, and then the fan 16, the exhaust fan 2 and the sprayer 10 are started to make them start working. When the staff is performing welding work, the smoke generated during welding will be sucked into the exhaust pipe. The dry filter layer of the welding smoke exhaust dust removal filtration system is composed of filter cotton 4, adsorption frame 5 and activated carbon 6. The smoke will first pass through the exhaust pipe into the filter cotton 4, and the filter cotton 4 can filter out slightly larger dust. Secondly, the smoke will pass through the two adsorption frames 5. In this process, the sprayer 10 will sprinkle clean water into the discharge pipe 1, and the water can precipitate the fine dust in the smoke. The adsorption frame 5 can filter the smoke again. Finally, the smoke will pass through the activated carbon 6. The activated carbon 6 has good adsorption capacity and can adsorb and filter harmful substances in the smoke. Finally, the filtered smoke is drawn away by the fan 16. The welding smoke exhaust dust removal filtration system uses filter cotton 4, adsorption frame 5 and activated carbon 6 to achieve dry filtration of flue gas, and uses a sprayer 10 to humidify the flue gas to achieve wet filtration. The use of double filtration can better filter dust and harmful substances in the flue gas, and the filtering effect is more significant, making the flue gas cleaner. When the welding smoke exhaust dust removal filtration system is not needed, the fan 16, the exhaust fan 2 and the sprayer 10 can be turned off in sequence. According to the design of the collection frame 12, the substances precipitated in the discharge pipe 1 can be collected. When cleaning is required, only the fixing member 13 needs to be removed from the discharge pipe 1 to clean the inside of the collection frame 12. When it is necessary to regularly clean the inside of the discharge pipe 1, the clamping rod 102 can be disassembled, the protective plate 101 can be opened, and the filter cotton 4, adsorption frame 5 and activated carbon 6 inside the discharge pipe 1 can be replaced.
