[0013] A method for using a welding and cutting fume automatic purification device comprises the following steps:

[0014] Step 1: Start the driving fan to extract the gas in the installation frame, and then suck the welding and cutting smoke into the L-shaped duct through the bellows and the collecting bucket. Then the welding and cutting smoke will be introduced into the upper end of the inner cavity of the treatment sphere and the dust in the welding and cutting smoke will be intercepted and filtered by the interception filter plate, and the welding and cutting smoke after preliminary treatment will be introduced into the vertical duct through the lower end of the inner cavity of the treatment sphere. Then the welding and cutting smoke after preliminary treatment will be introduced into the installation frame through the connecting elbow and the harmful gas in the welding and cutting smoke will be absorbed and treated by the treatment filter element, and the gas after secondary treatment will be discharged;

[0015] Step 2: At the same time, the welding and cutting smoke entering the L-shaped duct will pass through the first through slot and the second through slot in sequence, so that the welding and cutting smoke can fully contact the Z-shaped partition, and then the heat in the welding and cutting smoke can be fully introduced into the heat dissipation guide frame through the Z-shaped partition, and the driving fan can introduce part of the gas into the air supply duct and guide it to the heat dissipation guide frame by the air supply duct, so that the heat in the heat dissipation guide frame can be fully absorbed and taken away, thereby effectively reducing the temperature of the welding and cutting smoke guided to the interception filter plate, and further can play a good protective role on the interception filter plate;

[0016] Step three, when the welding and cutting smoke treatment operation is completed, the two limit hand wheels need to be rotated synchronously, so as to drive the two limit rotating rods to rotate synchronously, and then drive the two limit clamps to rotate synchronously and twist the corresponding limit torsion springs, and when the limit clamps rotate 180 degrees, stop rotating the limit hand wheels, and at this time the limiting force of the limit clamps on the limit clamp frame disappears, and then the two reset springs will drive the two sliding vertical rods to move downward synchronously through the sliding ring, thereby driving the sliding push plate to move downward, and then the used post-processing filter element can be gradually pushed out to install the outer frame, and the reset rack can be driven to move downward synchronously through the connecting vertical rod, and then the reset gear can be driven to rotate synchronously, and further the flip inner frame can be driven to rotate synchronously through the installation rotating rod, and when the flip inner frame is flipped 180 degrees, the positioning hole just corresponds to the positioning slide rod, and at this time the positioning spring will drive The positioning sleeve moves to the side close to the installation outer frame, so that the positioning slide bar can be inserted into the corresponding positioning socket, and then the sliding push plate and the flip inner frame can be limited and stabilized, and then the used treatment filter element can be pulled out and replaced. At the same time, under the action of gravity, the driving counterweight block will drive the driving screw to move downward, thereby driving the driven screw barrel to rotate, and then driving the cleaning rotating frame and the cleaning fan blades to rotate synchronously, so that the dust intercepted by the interception filter plate can be scraped off, and the cleaning fan blades can blow away the scraped dust. When the top of the treatment filter element after replacement contacts the sliding push plate, the driving grip bar is pulled, so that the two positioning slide bars can be reset and separated from the positioning socket, and then the sliding push plate is pushed up and reset, so that the flip inner frame can be reversed and reset and the driving counterweight block can be moved down and reset, and then the blocking bottom plate can be reset and fixed;

[0017] The fourth step is to rotate the auxiliary rotating rod, thereby driving the first gear, the rotating partition, the connecting ring and the toggle rotating rod to rotate synchronously, thereby twisting the reset torsion spring and driving the second gear to reverse, further driving the auxiliary turntable to reverse synchronously through the side connecting rotating rod, and stopping the rotation of the auxiliary rotating rod when the fixed cross bar moves to the vertical part of the L-shaped slot. At the same time, the toggle rotating rod will drive the first stabilizing plate to move through the toggle push groove, thereby driving the stabilizing rack 1 to move synchronously through the first side rod, and then driving the stabilizing rack 2 to move in the opposite direction through the stabilizing gear, and further through the stabilizing rack The second and second side rods drive the second stabilizing plate to move in the opposite direction, and when the auxiliary rotating rod stops rotating, the rotating partition can separate the vertical duct from the auxiliary vertical pipe, and the first stabilizing plate and the second stabilizing plate will be completely separated from the bottom end of the dust collecting cylinder, and then the dust collecting cylinder can be removed for cleaning, and after cleaning, the dust collecting cylinder will be reset and the auxiliary rotating rod will be released, and then the reset torsion spring will drive the rotating partition, the L-shaped slot and the toggle rotating rod to reverse and reset, thereby driving the first stabilizing plate and the second stabilizing plate to move in opposite directions, and then the cleaned dust collecting cylinder can be fixed again and its bottom end can be supported and stabilized.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the coordinated use of the dust treatment mechanism, the gas treatment mechanism and the connecting mechanism, the welding and cutting smoke can be effectively purified step by step for dust and gas, and the flip inner frame can be synchronously flipped 180 degrees while replacing the treatment filter element, and the sliding push plate and the flip inner frame can be limited and stabilized, thereby effectively improving the stability of the flip inner frame after rotation and being able to drive the driving screw to move downward under the action of gravity, thereby driving the driven screw barrel to rotate, and then driving the cleaning rotating frame and the cleaning fan blades to rotate synchronously, so that the dust intercepted by the interception filter plate can be scraped off, thereby realizing the automatic flipping and cleaning of the interception filter plate, without manual cleaning, thus saving manpower, and the cleaning fan blades can blow away the scraped dust, thereby effectively improving the cleaning effect of the interception filter plate, and when the post-replacement treatment filter element is pushed up and reset, the flip inner frame can be reversed and reset, and the driving counterweight block can be moved down and reset;

[0020] 2. Through the setting and use of the cooling mechanism, the welding and cutting smoke entering the L-shaped duct will pass through the first through slot and the second through slot in sequence, so that the welding and cutting smoke can fully contact the Z-shaped partition, and then the heat in the welding and cutting smoke can be fully introduced into the heat dissipation guide frame through the Z-shaped partition, and the driving fan can introduce part of the gas into the air supply duct and guide it to the heat dissipation guide frame by the air supply duct, so that the heat in the heat dissipation guide frame can be fully absorbed and taken away, thereby effectively reducing the temperature of the welding and cutting smoke guided to the interception filter plate, and further can play a good protective role on the interception filter plate;

[0021] 3.

[0041] A method for using a welding and cutting fume automatic purification device comprises the following steps:

[0042] Step 1: Start the driving fan 33, so that the gas in the installation outer frame 32 can be extracted, and then the welding and cutting smoke can be sucked into the L-shaped duct 22 through the bellows 24 and the collecting bucket 25, and then the welding and cutting smoke will be introduced into the upper end of the inner cavity of the processing sphere 21, and the dust in the welding and cutting smoke will be intercepted and filtered by the interception filter plate 28, and the welding and cutting smoke after preliminary treatment will be introduced into the vertical duct 23 through the lower end of the inner cavity of the processing sphere 21, and then the welding and cutting smoke after preliminary treatment will be introduced into the installation outer frame 32 through the connecting elbow 31, and the harmful gas in the welding and cutting smoke will be absorbed and treated by the processing filter element 34, and the gas after secondary treatment will be discharged;

[0043] Step 2: At the same time, the welding smoke entering the L-shaped duct 22 will pass through the first through slot 52 and the second through slot 53 in sequence, so that the welding smoke can fully contact the Z-shaped partition 51, and then the heat in the welding smoke can be fully introduced into the heat dissipation guide frame 54 through the Z-shaped partition 51, and the driving fan 33 can introduce part of the gas into the air delivery duct 55 and guide it to the heat dissipation guide frame 54 by the air delivery duct 55, so that the heat in the heat dissipation guide frame 54 can be fully absorbed and taken away, thereby effectively reducing the temperature of the welding smoke guided to the interception filter plate 28, and further can play a good protective role on the interception filter plate 28;

[0044] When the welding smoke treatment operation is completed, the two limit hand wheels 39 need to be rotated synchronously, so as to drive the two limit rotating rods 38 to rotate synchronously, and then drive the two limit clamping blocks 311 to rotate synchronously and twist the corresponding limit torsion springs 310. When the limit clamping block 311 rotates 180 degrees, the limit hand wheel 39 stops rotating, and the limiting force of the limit clamping block 311 on the limit clamping frame 36 disappears at this time. Then the two reset springs 45 will drive the two sliding vertical rods 43 to move downward synchronously through the sliding collar 44, so as to drive the sliding push plate 41 to move downward, and then the used post-processing filter element 34 can be gradually pushed out of the installation outer frame 32, and the reset rack 47 can be driven to move downward synchronously through the connecting vertical rod 46, and then the reset gear 48 can be driven to rotate synchronously, and further, the flip inner frame 27 can be driven to rotate synchronously through the installation rotating rod 26, and when the flip inner frame 27 is flipped 180 degrees, the positioning hole 411 just corresponds to the positioning slide rod 42, and the positioning spring 410 will drive the positioning slide rod 42 to rotate synchronously. The positioning collar 49 moves toward the side close to the mounting outer frame 32, so that the positioning slide rod 42 can be inserted into the corresponding positioning hole 411, and then the sliding push plate 41 and the flip inner frame 27 can be limited and stabilized, and then the used treatment filter element 34 can be extracted and replaced. At the same time, under the action of gravity, the driving counterweight block 214 will drive the driving screw 215 to move downward, thereby driving the driven screw barrel 29 to rotate, and then driving the cleaning rotating frame 210 and the cleaning fan blades 211 to rotate synchronously. The dust intercepted by the interception filter plate 28 can be scraped off, and the cleaning fan blades 211 can blow away the scraped dust. When the top of the post-processing filter element 34 contacts the sliding push plate 41, the driving grip 412 is pulled, so that the two positioning slide bars 42 can be reset and separated from the positioning sockets 411. Then, the sliding push plate 41 is pushed up and reset, so that the flip inner frame 27 can be reversed and reset, and the driving counterweight block 214 can be moved down and reset, and then the blocking bottom plate 35 can be reset and fixed.

[0045] Step 4, rotate the auxiliary rotating rod 73, so as to drive the first gear 75, the rotating partition 74, the connecting ring 81 and the toggle rotating rod 83 to rotate synchronously, and then the reset torsion spring 76 can be twisted and the second gear 78 can be driven to reverse, and the auxiliary rotating disk 79 can be driven to reverse synchronously through the side rotating rod 77, and the auxiliary rotating rod 73 is stopped when the fixed cross bar 61 moves to the vertical part of the L-shaped slot 710. At the same time, the toggle rotating rod 83 will drive the first stabilizing plate 88 to move by toggling the pushing groove 89, so that the stabilizing rack 1 85 can be driven to move synchronously through the first side rod 87, and then the stabilizing rack 2 86 can be driven to move in the opposite direction through the stabilizing gear 84, and further the stabilizing rack 2 86 and the second side rod 810 drive the second stabilizing plate 811 to move in the opposite direction, and when the auxiliary rotating rod 73 stops rotating, the rotating partition 74 can separate the vertical duct 23 from the auxiliary vertical pipe 72, and the first stabilizing plate 88 and the second stabilizing plate 811 will be completely separated from the bottom end of the dust collecting cylinder 6, and then the dust collecting cylinder 6 can be removed for cleaning, and after cleaning, the dust collecting cylinder 6 is reset and the auxiliary rotating rod 73 is released, and then the reset torsion spring 76 will drive the rotating partition 74, the L-shaped slot 710 and the toggle rotating rod 83 to reverse and reset, thereby driving the first stabilizing plate 88 and the second stabilizing plate 811 to move in opposite directions, and then the cleaned dust collecting cylinder 6 can be fixed again and its bottom end can be supported and stabilized.

After cleaning, the dust collecting cylinder (6) is reset and the auxiliary rotating rod (73) is released, and then the reset torsion spring (76) drives the rotating partition plate (74), the L-shaped slot (710) and the toggle rotating rod (83) to reverse and reset, thereby driving the first stabilizing plate (88) and the second stabilizing plate (811) to move in opposite directions, and then the cleaned dust collecting cylinder (6) can be fixed again and its bottom end is supported and stabilized.
