Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figure 1-4 As shown, an embodiment of this utility model discloses a self-circulating welding fume purifier with intelligent air supply temperature regulation, comprising a main body 1, and further comprising: The fan chamber 101, backflushing chamber 102, and filter cartridge chamber 103 are arranged sequentially from top to bottom inside the main body 1. The main body 1 serves as the core load-bearing structure, featuring an overall vertical cabinet design. It is made of cold-rolled steel plate with powder coating, providing excellent rust resistance and wear resistance. The internal space of the main body 1 is functionally divided from top to bottom into the fan chamber 101, backflushing chamber 102, and filter cartridge chamber 103. Each chamber is separated by a sealed partition to ensure airflow follows a preset path and prevents leakage of unpurified dust. A suction duct 4 is connected to the rear side of the main body 1, and its lower end is connected to the side wall of the filter chamber 103. The suction duct 4 is made of galvanized steel pipe, and its lower end is connected to the side wall of the filter chamber 103 through a flange, forming a channel for smoke and dust to enter the filter chamber. Exhaust vents 13 are symmetrically arranged at the upper part of the main body 1, and are connected to the fan chamber 101. An exhaust duct 14 is connected to the outside of the exhaust vents 13, and is located inside the main body 1. Air outlet louvers 15 are located on the side wall of the main body 1 and are connected to the exhaust duct 14. Exhaust vents 13 are symmetrically arranged at the upper part of the main body 1, and are connected to the fan chamber 101 by welding, guiding the purified gas output from the fan chamber into the exhaust duct 14. The exhaust duct 14 is made of PP... The material is galvanized steel pipe, which is fixed inside the main body 1 by buckle. Its end is connected to the air outlet louver 15 on the side wall of the main body 1, so as to realize the directional delivery of purified gas.

[0017] An air inlet 2 is provided on one side of the upper end face of the main body 1, and the air inlet 2 is connected to the air intake pipe 4. A spark catcher 3 is fixed on the upper end face of the air inlet 2. The air inlet 2 can be used to guide the gas, and the spark catcher 3 has the functions of "flame arrest + pre-filtration". Functionally, it intercepts large particles of welding slag and sparks, preventing high-temperature sparks from entering the main filtration area and causing safety hazards such as fire in the filter cartridge 6. The filter cartridge chamber 103 includes a support frame 5 and filter cartridges 6. The support frame 5 is symmetrically fixed inside the filter cartridge chamber 103, and the filter cartridges 6 are arranged inside the support frame 5. There are 6 sets of filter cartridges 6. The position of the filter cartridges 6 can be limited by the support frame 5, which can facilitate the subsequent disassembly, cleaning and installation of the filter cartridges 6. Then, the filter cartridges 6 can capture metal dust and welding fume particles in the smoke and dust through physical interception, diffusion adsorption and other effects, purifying the air. A filter cartridge cover can be set on the top of the filter cartridges 6 to seal and fix the filter cartridges, prevent unfiltered smoke and dust from leaking out, and ensure purification efficiency. Some designs include a quick-release structure for easy replacement and cleaning of the filter cartridges. The fan chamber 101 includes a support frame A8, a motor 9, fan blades 10, and sound-absorbing plates 11. The support frame A8 is fixed inside the fan chamber 101, the motor 9 is fixed inside the support frame A8, and the fan blades 10 are fixed to the output end of the motor 9. The sound-absorbing plates 11 are evenly distributed on the inner wall of the fan chamber 101. The support frame A8 can limit the motor 9, preventing it from shifting or shaking. The motor 9 drives the fan blades 10 to rotate, creating a negative pressure in the suction duct 4, which draws welding fumes from the outside into the equipment. This is the system's "power source," determining the equipment's suction power and processing air volume. The inner wall of the fan chamber 101 is evenly covered with sound-absorbing plates 11, which are made of centrifugal glass wool and covered with an aluminum foil moisture-proof layer, effectively absorbing noise generated by the motor and airflow. An indoor evaporation module 12 is installed at the upper end of the fan chamber 101, and the indoor evaporation module 12 is located inside the main body 1. The indoor evaporation module 12 is fixed to the upper end of the fan chamber 101 by bolts. The indoor evaporation module 12 is located inside the main body 1 and is connected to the external refrigeration / heating system. It exchanges heat with the evaporation coil through copper pipes. When the purified gas flows through the indoor evaporation module, the gas temperature can be automatically adjusted according to the set temperature to achieve intelligent control of the air supply temperature and avoid the purified gas temperature being too low or too high, which would affect the workshop environment. The backflush chamber 102 includes a steam drum 7 and backflush valves 701. The steam drum 7 is fixed in the center of the backflush chamber 102 and is symmetrically arranged. The backflush valves 701 are symmetrically arranged on the left and right sides of the steam drum 7. The backflush chamber 102 is located above the filter cartridge chamber 103. Two sets of steam drums 7 are symmetrically fixed in the center of its interior by bolts. The steam drum 7 is a stainless steel pressure vessel, whose main function is to store compressed air and stabilize the air pressure, providing a continuous and stable air source for the backflush system. The backflush valves 701 are symmetrically arranged on the left and right sides of the steam drum 7 by threaded connections. The backflush valves 701 are electromagnetic pulse valves. The backflush valve is located above a set of filter cartridges 6 and is connected to the filter cartridges 6 via a blowpipe. When there is a lot of dust on the surface of the filter cartridges, the backflush valve 701 opens at regular intervals. Compressed air in the steam drum 7 is ejected through the backflush valve to form a high-speed airflow that sweeps the surface of the filter cartridges, causing the dust to fall off and restoring the filter cartridge's filtration performance. A funnel 16 is fixed to the lower end face of the main body 1. A hopper 17 is slidably engaged at the bottom of the ash funnel 16. The funnel 16 is welded and fixed to the lower end face of the main body 1. The funnel 16 adopts a conical structure, and the upper diameter matches the bottom size of the filter cartridge chamber 103, which can concentrate and guide the dust falling off the filter cartridges and the dust collected in the filter cartridge chamber to the bottom. The bottom of the funnel 16 is slidably connected to the bucket 17 via a slide rail. The bucket 17 is made of plastic or stainless steel and has a handle at the front end for easy pulling and cleaning by the operator. A rubber sealing strip is set at the connection between the bucket 17 and the funnel 16 to prevent dust leakage. When the dust in the bucket reaches a certain amount, the bucket can be directly pulled out for emptying and cleaning, making the operation convenient.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
