Description

Technical Field

[0001] The invention relates to the technical field of purifiers, in particular to a welding fume purifier. Background Art

[0002] Welding fume purifier is a purification device specially designed for industrial welding fume and light particles. It is light, flexible and easy to operate. It is widely used in chemical, electronic, metal processing and other industries. A large amount of fume will be generated during metal welding. The fume will be suspended in the workshop. If it is not handled in time, it will be inhaled into the human lungs and affect human health. Therefore, the harmful fume must be purified before it enters the welder's breathing zone.

[0003] The Chinese patent publication number is CN208975390U, which discloses a welding fume purifier, including a filter cartridge, a box body and a centrifugal fan installed inside the box body. A back panel is provided on the back of the box body, and a support plate is provided in the middle of the box body. The support plate divides the interior of the box body into two parts. The two ends of the filter cartridge are respectively fixed on the back panel and the support plate. The filter cartridge is inclined, and a filter cartridge cover is provided at the connection between the filter cartridge and the back panel. An air inlet is provided at the upper end of the box body, and the air inlet is located above the filter cartridge. The centrifugal fan is installed at the lower end of the box body, an air suction port is provided at the upper end of the centrifugal fan, and an air outlet is provided at the lower end of the centrifugal fan. The air outlet is arranged at the front of the box body, and a sliding door is provided at the upper end of the air outlet, which is fixed on the box body. The suction force of the centrifugal fan generates a negative pressure inside the box body, so that the smoke enters the box body and is filtered by the filter cartridge to meet the emission standards.

[0004] During the operation of the device, a large amount of high-temperature welding slag will be generated due to the welding operation. These high-temperature welding slags will be sucked into the box through the air intake port. When these high-temperature welding slags come into contact with the surface of the filter cartridge, they will fall and accumulate on the filter cartridge. This continuous high temperature and physical impact will damage the filter cartridge, resulting in structural damage or reduced filtration efficiency. Once the filter cartridge is damaged, the smoke generated by the welding can overflow through the damaged part of the filter cartridge, thereby reducing the filtration quality of the entire system.

[0049] Specifically, Figure 1-Figure 10 As shown, a fixed block 206 is fixedly installed on the side of the filter plate 201, a moving rod 207 is slidably installed on the top surface of the fixed block 206, a fixed plate 208 is fixedly installed on the bottom surface of the moving rod 207, an arc plate 209 is fixedly installed on the bottom surface of the fixed plate 208, the outer wall of the arc plate 209 is slidably connected to one end of the rotating rod 205, an elastic member 210 is fixedly installed on the top surface of the fixed plate 208, the upper end of the elastic member 210 is fixedly connected to the bottom surface of the fixed block 206, and a limiting plate 217 is fixedly installed on the side of the upper end of the moving rod 207.

[0050] In this embodiment, the arc plate 209 is pushed to move by the rotating rod 205 , and the arc plate 209 drives the fixed plate 208 to move. Under the joint action of the elastic member 210 , the fixed plate 208 is made to reciprocate up and down.

[0051] Specifically, Figure 1-Figure 10 As shown, two T-shaped slots 211 are provided on the side of the fixing plate 208 , and T-shaped blocks 212 are slidably mounted on the inner walls of the two T-shaped slots 211 , and connecting rods 213 are rotatably mounted on the sides of the two T-shaped blocks 212 .

[0052] In this embodiment, the T-shaped block 212 is limited by the T-shaped slot 211 , and the T-shaped block 212 slides inside the T-shaped slot 211 .

[0053] Specifically, Figure 1-Figure 10 As shown, the other ends of the two connecting rods 213 are fixedly connected to the sides of the two scrapers 214 respectively, and two arc grooves 216 are formed through the side of the filter plate 201. The inner walls of the two arc grooves 216 are slidably connected to the outer walls of the two connecting rods 213 respectively.

[0054] In this embodiment, the scraper 214 is provided to scrape off the welding slag on the side of the filter plate 201 , so that the welding slag is not easy to block the filter holes of the filter plate 201 .

[0055] The vibration mechanism 3 is arranged at one side of the filter plate 201 . The vibration mechanism 3 comprises a knocking head 304 located at one side of the filter plate 201 .

[0056] Specifically, Figure 1-Figure 10 As shown, a mounting groove 301 is provided on the top surface of the moving rod 207 , a fixing frame 302 is fixedly installed on the top surface of the fixing block 206 , and the inner wall of the fixing frame 302 is hinged to the middle outer wall of the knocking rod 303 .

[0057] In this embodiment, the knocking rod 303 and the knocking head 304 are provided, and the knocking rod 303 drives the knocking head 304 to rotate and knock the filter plate 201, so that the filter plate 201 vibrates and shakes off the welding slag.

[0058] Specifically, Figure 1-Figure 10 As shown, the outer wall of the other end of the knock rod 303 is provided with two slide grooves 305, and the inner wall of the mounting groove 301 is fixedly installed with two fixing columns 306, and the two fixing columns 306 are slidably connected with the inner walls of the two slide grooves 305 near the outer wall of the end.

[0059] In this embodiment, the fixed column 306 is slidably connected to the inner wall of the sliding groove 305, thereby driving the knocking rod 303 to rotate.

[0060] The specific solution is as follows: the suction hood 107 is moved to above the welding part, and the fan 112 is turned on. The fan 112 absorbs smoke and dust through the suction hood 107. The filter plate 201 is set to block and filter the high-temperature welding slag entering the interior of the purifier body 1, so that the high-temperature filter residue is not easy to fall directly onto the filter cartridge 117 and damage the filter cartridge 117. The wind force through the air inlet 105 drives the fan blade 204 and the rotating shaft 203 to rotate. When the rotating shaft 203 drives the rotating rod 205 to rotate and contact the arc plate 209, the rotating rod 205 pushes the arc plate 209, the fixed plate 208 and the moving rod 207 to move upward, and the fixed plate 208 drives the connecting rod 213 to rotate in the arc groove 216 through the T-shaped groove 211. The connecting rod 213 drives the scraper 214 to swing. After the rotating rod 205 is separated from the arc plate 209, the fixed plate 208 is driven to move downward and return to its original position under the action of the elastic member 210. Thereby, the scraper 214 is driven to swing to its original position, and then the scraper 214 continuously removes the welding slag on the surface of the filter plate 201, so that the welding slag is not easy to block the filter plate 201. The filter plate 201 further blocks the welding slag and allows the smoke to pass through, thereby improving the filtration efficiency. When the moving rod 207 moves up and down, the moving rod 207 drives the fixed column 306 to move up and down through the installation groove 301. When the fixed column 306 moves up and down, it drives one end of the knocking rod 303 to swing up and down through the slide groove 305. The other end of the knocking rod 303 drives the knocking head 304 to swing up and down and knock the filter plate 201, so that the filter plate 201 vibrates. When the filter plate 201 vibrates, the welding slag on the surface is shaken off to ensure the cleanliness of the filter plate 201. The filter plate 201 blocks the welding slag and allows the smoke to pass through, thereby further improving the filtration efficiency. The smoke is then filtered by the filter cartridge 117 and discharged from the air outlet 113.
