DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1

[0027] Combination Figure 1-5 As shown, this embodiment provides an environmentally friendly electric welding machine with a fume purification function, including: an electric welding machine body 100 and a purification module 200.

[0028] The electric welding machine body 100 is used to supply current to the welding gun, so as to facilitate the welding operation of the welding gun.

[0029] The purification module 200 is fixed on one side of the welding machine body 100 and is used to purify the fume generated during welding. It includes a shell 210 fixed on one side of the welding machine body 100, an air supply pipe 220 installed on the top of the shell 210 and connecting the inner cavity of the welding machine body 100 and the shell 210, a primary filter 230 fixed on the inner wall of the shell 210, a plurality of high-speed fans 240 installed on the inner wall of the shell 210 and located above the primary filter 230, a filter element 250 embedded in the inner cavity of the shell 210 and fixed to the shell 210 by magnetic attraction, a cooling element 260 fixed on the inner wall of the shell 210, a water inlet pipe installed on one side of the shell 210 and connected to the inner cavity of the shell 210, a water outlet pipe installed on the other side of the shell 210 and connected to the inner cavity of the shell 210, and a bellows 290 installed on one side of the shell 210 and connected to the cavity of the shell 210 below the primary filter 230.

[0030] The shell 210 is fixed on the welding machine body 100 to form a sealed space. The air supply pipe 220 is used to send the purified smoke into the inner cavity of the welding machine body 100 to increase the air flow rate in the inner cavity, thereby improving the heat dissipation performance of the welding machine body 100.

[0031] The air supply pipe 220 includes a tube body 221 connecting the top of the shell 210 and the inner cavity of the electric welding machine body 100, a gas sensor 222 installed at the top of the tube body 221 and extending into the tube body 221, and an alarm light 223 installed at the top of the tube body 221. The tube body 221 facilitates the purified flue gas to be delivered into the inner cavity of the electric welding machine body 100. The gas sensor 222 is used to monitor the content of toxic molecules in the flue gas after purification in real time. When the content of toxic molecules in the purified flue gas is higher than the set value, it can be judged that the filter element 250 is in a saturated state and needs to be replaced. At this time, the alarm light 223 is started to prompt the workers, so that the workers can replace the filter element 250 in time.

[0032] The primary filter 230 is used to perform preliminary filtration on the smoke and remove dust particles in the smoke. One end of the bellows 290 is connected to the cavity of the shell 210 located below the primary filter 230, so that the smoke can enter the shell 210 and be filtered through the primary filter 230. The high-speed fan 240 is used to suck the smoke into the inner cavity of the shell 210 to facilitate the purification of the smoke.

[0033] In addition, a mesh frame 291 is provided at the end of the bellows 290 , so that clogging of the end of the bellows 290 can be avoided.

[0034] The filter element 250 is used to filter toxic and harmful molecules in the flue gas, and includes a mesh box 251 movably embedded in the inner cavity of the shell 210 and activated carbon particles 252 filled in the inner cavity of the mesh box 251. The mesh box 251 is used to load the activated carbon particles 252 and facilitate the passage of flue gas. The activated carbon particles 252 are used to adsorb toxic and harmful molecules in the flue gas.

[0035] In addition, a pull ring 2511 is fixed on one side of the mesh box 251 to facilitate the removal of the mesh box 251 from the shell 210. Magnets 2512 are symmetrically fixed on both sides of the mesh box 251. The magnets 2512 are adsorbed on the surface of the shell 210 and fixed by magnetic attraction, which facilitates the installation and disassembly of the mesh box 251.

[0036] The cooling element 260 is used to cool the flue gas, and includes a partition 261 symmetrically fixed on the inner wall of the shell 210 and a plurality of heat pipes 262 arranged relative to the partition 261. A sealed cavity is formed between the relative partition 261 and the inner wall of the shell 210. The water inlet pipe 270 and the water outlet pipe 280 are both connected to the cavity, and are used to send cooling water into the cavity or send out the cooling water after absorbing heat. The heat pipe 262 is made of copper alloy material and has excellent thermal conductivity. When the purified flue gas passes through the heat pipe 262, it can exchange heat with the cooling water on the outside through the heat pipe 262, thereby cooling the flue gas.

[0037] The working principle and use process of the utility model are as follows: when performing welding operations, the mesh frame 291 at the end of the bellows 290 is placed near the working position, and the high-speed fan 240 is started. The high-speed fan 240 is started, and the welding fume near the mesh frame 291 is sucked into the inner cavity of the shell 210 through the bellows 290. After the fume enters the inner cavity of the shell 210, it is filtered through the primary filter 230 to remove dust particles in the fume. Then the fume enters the filter element 250, and the toxic and harmful molecules in the fume are adsorbed by the activated carbon particles 252. The purified fume enters the heat pipe 262. At this time, cooling water enters the cavity formed by the relative partition 261 and the shell 210 through the water inlet pipe 270. When the fume passes through the heat pipe 262, the heat in the fume is removed by The heat pipe 262 exchanges heat with the cooling water to cool the flue gas. The cooled flue gas enters the tube body 221 and enters the electric welding machine body 100 through the tube body 221, thereby improving the air flow rate in the inner cavity of the electric welding machine body 100, that is, improving the heat dissipation performance of the electric welding machine body 100. In addition, the gas sensor 222 monitors the toxic molecule content of the flue gas in the tube body 221 in real time. When the toxic molecule content in the purified flue gas is higher than the set value, it can be determined that the activated carbon particles 252 are in a saturated state and need to be replaced. At this time, the alarm light 223 is started to prompt the worker. The worker pulls out the mesh box 251, pours out the saturated activated carbon particles 252, replaces them with new activated carbon particles 252, and then embeds the mesh box 251 into the shell 210.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
