Description

Technical Field

[0001] This utility model relates to the field of welding dust removal and fume extraction technology, specifically a dust removal and fume extraction device for welding equipment. Background Technology

[0002] In the current field of welding dust removal technology, welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Potential injuries to the human body from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation.

[0003] The toxic gases and fumes generated during welding need to be removed to reduce their impact on the human body. However, current welding dust removal equipment has low dust removal efficiency and is inconvenient to use, requiring manual adjustment.

[0004] As disclosed in Chinese Patent CN216418790U, a dust removal and fume extraction device for welding equipment is described. A sliding device adjusts the position of the suction pipe via a slider. The conical hood and suction pipe are aligned with the welding section. Activating the device activates the suction fan, which accelerates the airflow, drawing in harmful gases and dust through the suction pipe. These gases and dust enter the dust removal chamber. A booster pump connects to an air source, blowing air through nozzles and causing dust to fall and pass through the dust collection rollers. Simultaneously, a drive motor rotates two dust collection rollers. The rollers absorb and filter dust through dust collection bags. Air enters the spray chamber, where a water pump draws water into the spray pipes, which is then sprayed onto a water curtain through multiple nozzles. The water-soaked water curtain wets the air, effectively removing dust and smoke, reducing the smoke content in the air, and purifying the air. The exhaust port facilitates the discharge of smoke and dust for centralized treatment.

[0005] However, the fume treatment devices used in existing welding equipment are not easily adjustable according to the welding position during use, thus failing to effectively adsorb and collect welding fumes to achieve better fume treatment results.

[0006] Therefore, we urgently need to provide a dust removal and fume extraction device for welding equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Example 1:

[0028] The existing fume treatment devices for welding equipment are not easily adjustable to different welding positions, thus hindering effective fume adsorption and collection for better fume treatment. Please refer to [reference needed]. Figures 1-3 The embodiment provides a dust removal and fume extraction device for welding equipment, which can effectively improve the adsorption and collection effect of welding fumes, thereby effectively reducing the harm of welding fumes. The dust removal and fume extraction device for welding equipment includes a welding workbench 1, an adjustment device is installed on the back and top of the welding workbench 1, a purification device is installed on the top and back of the adjustment device, and an exhaust device is installed on the back of the purification device.

[0029] The adjustment device includes a position adjustment structure and a height adjustment structure, with the height adjustment structure mounted on top of the position adjustment structure. The height adjustment structure includes an electric push rod 105, with a lifting plate 106 mounted at its output end. A fume hood 107 is connected to the left end of the lifting plate 106, and a telescopic tube 108 is mounted at the top of the fume hood 107. A connecting tube 109 is connected to the top of the telescopic tube 108. The position adjustment structure includes an adjustment slot 101, with an asynchronous motor 102 mounted at its right end. An adjustment rod 103 is connected to the output end of the asynchronous motor 102, and an adjustment frame 104 is connected to the middle of the outer surface of the adjustment rod 103.

[0030] The front of the adjustment groove 101 is fixedly connected to the top back of the welding workbench 1, the bottom of the adjustment frame 104 is slidably connected to the inner wall of the adjustment groove 101, the electric push rod 105 is detachably installed on the top of the adjustment frame 104, and the outer surface of the connecting pipe 109 is fixedly connected to the middle of the top surface of the adjustment frame 104.

[0031] By adjusting the device, the electric push rod 105 drives the fume hood 107 to rise and fall, and the adjusting rod 103 drives the adjusting frame 104 to adjust its position, thereby facilitating better adsorption and collection of welding fumes as the welding position changes.

[0032] When the welding position changes and the position of the welding fume adsorption needs to be adjusted, the asynchronous motor 102 is started to drive the adjusting rod 103 to rotate. The adjusting rod 103 is a threaded rod with threads on its outer surface, and its outer surface is threaded to the middle of the bottom end of the adjusting frame 104. At the same time, the bottom end of the adjusting frame 104 is slidably connected to the middle of the adjusting groove 101. Thus, the position of the fume hood 107 is adjusted by the adjusting frame 104. Then, the electric push rod 105 is started to drive the lifting plate 106 to rise and fall. Since the lifting plate 106 is fixedly connected to the fume hood 107, and the top of the fume hood 107 is fixedly connected to the telescopic tube 108, the height of the fume hood 107 can be flexibly adjusted, effectively enhancing the adsorption and collection effect of welding fumes.

[0033] Example 2:

[0034] Based on Implementation 1, the existing technology still has issues regarding the purification and filtration effect of welding fumes after adsorption and collection. Please refer to... Figures 4-5This embodiment provides a dust removal and fume extraction device for welding equipment, which can effectively solve the problem of adsorbing and collecting welding fumes and enhance the purification and filtration effect of welding fumes. The dust removal and fume extraction device for welding equipment includes a purification device including a purification cylinder 202. A guide tube 201 is installed on the center of the front of the purification cylinder 202 near the bottom. A guide plate 203 is fixedly installed inside the purification cylinder 202. A nozzle 204 is installed on the center of the top surface of the purification cylinder 202. The bottom end of the purification cylinder 202 is fixedly connected to the center of the top surface of the adjusting frame 104 near the back. The end of the guide tube 201 away from the purification cylinder 202 is fixedly connected to the top end of the connecting pipe 109.

[0035] The emission device includes an exhaust pipe 301, a filter plate 302 installed inside the exhaust pipe 301, a drain pipe 303 installed in the middle of the bottom end of the exhaust pipe 301, and an exhaust fan 304 installed inside the bottom end of the exhaust pipe 301 near the back. The top end of the exhaust pipe 301 is fixedly connected to the inner wall of a rectangular hole in the middle of the back of the purification cylinder 202. The outer surface of the filter plate 302 is slidably and sealingly connected to the inner wall of the rectangular hole in the middle of the outer surface of the exhaust pipe 301.

[0036] By setting up purification and emission devices, the welding fumes are purified by spiral guidance of the guide plate 203 and spraying of purification liquid by the nozzle 204. Then, the welding fumes are effectively treated and discharged by filtration of the filter plate 302.

[0037] When adsorbing welding fumes, the exhaust fan 304 is activated to create a negative pressure inside the pipeline. The fume hood 107 then adsorbs and collects the welding fumes. After entering the purification cylinder 202 through the guide pipe 201, the welding fumes are guided by the spiral of the guide plate 203. At the same time, the purification liquid is atomized and sprayed by the nozzle 204, which effectively enhances the mixing reaction between the welding fumes and the purification liquid. The welding fumes then enter the exhaust pipe 301, where multiple filter plates 302 filter and adsorb the welding fumes, effectively reducing the harm caused by the emission of welding fumes. The purified liquid after the reaction is then discharged through the drain pipe 303, while the smoke is emitted by the exhaust fan 304.
