Description

Technical Field

[0001] This utility model relates to the technical field of plasma cutting fume adsorption and purification equipment, and in particular to a plasma cutting machine fume adsorption and purification mechanism. Background Technology

[0002] With the widespread application of plasma cutting machines, the problem of smoke pollution has always been a major concern. Traditional smoke adsorption and purification methods have many drawbacks, posing serious challenges to the working environment and ecological protection. Early common single-filtration purification methods, relying on simple filtration devices, cannot effectively cope with the complexity of smoke composition. Single filtration cannot comprehensively remove these pollutants, resulting in low air cleanliness after purification. A large amount of harmful smoke is emitted into the atmosphere, exacerbating environmental pollution phenomena such as smog, seriously violating the increasingly stringent national industrial waste gas emission standards, and causing great damage to the ecological environment. Moreover, the filter plates of traditional purification equipment have complex installation and disassembly structures. Maintenance personnel need to spend a lot of time and effort, using specialized tools for cumbersome operations, when cleaning or replacing clogged filter plates. This not only leads to long equipment downtime, affecting production efficiency, but also increases maintenance costs. Due to the inconvenience of maintenance, filter plates cannot be cleaned or replaced in a timely manner. As the usage time increases, the filtration performance declines significantly, making it difficult to continuously and effectively adsorb and purify smoke, and failing to provide reliable protection for the working environment. Therefore, we propose a plasma cutting machine smoke adsorption and purification mechanism to solve this problem. Utility Model Content

This greatly improves the cleanliness of the purified air and, compared to a single filtration purification method, can more comprehensively remove various pollutants, thus contributing to the protection of the ecological environment.

Placement slots are opened on both sides of the purification box 13. A disassembly component 8 is provided inside the two placement slots. The disassembly component 8 includes a pull plate 801. Two sets of inclined rods 802 are slidably abutted inside the pull plate 801. The two sets of inclined rods 802 are respectively movably inserted into the interior of the primary filter plate 11 and the secondary filter plate 12.

[0021] In this embodiment, a purification component 9 is provided on one side of the purification box 13. The purification component 9 includes a water tank 901, a short pipe fixedly installed inside the top of the water tank 901, a connecting pipe 904 provided at the top of the short pipe, a water box 905 fixedly installed at one end of the connecting pipe 904, and multiple sets of water mist nozzles 906 fixedly installed on one side of the water box 905. The water box 905 and the multiple sets of water mist nozzles 906 are both located inside the purification box 13 to facilitate the purification of the fumes generated during cutting. Two sets of pull plates 801 are slidably installed on opposite sides. Inside the corresponding placement slot, a connecting shaft 803 is fixedly installed on one side of each of the two sets of pull plates 801. The two sets of connecting shafts 803 slide through to both sides of the purification box 13. A spring 804 is sleeved on the outer side of each of the two sets of connecting shafts 803. The two ends of the two sets of springs 804 are fixedly connected to the corresponding pull plate 801 and the inner wall of one side of the placement slot, respectively. A pull block is fixedly installed on one end of each of the two sets of connecting shafts 803 to facilitate the quick reset of the pull plate 801 and to facilitate the quick installation and removal of the primary filter plate 11 and the secondary filter plate 12.

[0022] In this embodiment, the water tank 901 is fixedly connected to the purification tank 13. The top of the water tank 901 is fixedly installed with a pump body 903 and a water inlet pipe 902. The two ends of the pump body 903 are fixedly connected to a short pipe and a connecting pipe 904, respectively, so that the water source can be quickly sprayed out from the water mist nozzle 906. The two sets of limit rods 805 are slidably installed inside the two sets of pull plates 801. The two ends of the two sets of limit rods 805 are fixedly connected to the inner walls of the corresponding placement slots on both sides, so that the pull plates 801 can slide stably. An exhaust pipe and a drain pipe are fixedly installed on one side of the purification tank 13. A door 15 is rotatably installed on one side of the purification tank 13, so that the primary filter plate 11 and the secondary filter plate 12 can be pulled out from the inside of the purification tank 13.

[0023] In this embodiment, during use, the electric support 2 can slide flexibly under the action of two sets of sliding grooves inside the workbench 1, adjusting its position according to cutting requirements. After adjustment, the cylinder 14 is activated, and its output end pushes the cutting blade 3 downward, preparing to cut the workpiece. When the cutting blade 3 starts working and generates smoke and dust, the dust hood 4 is installed near the cutting blade 3, effectively collecting the smoke and dust generated during the cutting process. The dust suction pipe 5 connects the dust hood 4 to the vacuum cleaner 6. After the vacuum cleaner 6 is activated, it generates strong suction through the dust suction pipe 5, drawing the smoke and dust near the dust hood 4 into the vacuum cleaner 6. After the smoke and dust are drawn into the vacuum cleaner 6, they are then... The dust outlet pipe 7 discharges into the dust discharge shell 10 inside the purification chamber 13. The structural design of the dust discharge shell 10 allows the smoke and dust to be distributed more evenly after entering the purification chamber 13. Through the primary filter plate 11 and the secondary filter plate 12, larger particles in the smoke and dust are intercepted by the primary filter plate 11. The secondary filter plate 12 filters the smoke and dust again after primary filtration and water mist purification, intercepting the remaining small particles and impurities that have not been adsorbed by the water mist, making the purified air cleaner. At this time, the water in the water tank 901 is drawn from the water inlet pipe 902 under the action of the pump body 903, enters the connecting pipe 904 through the short pipe, and finally reaches the water box 905. Multiple water mist nozzles 906 on one side of the water box 905 atomize water and spray it onto the smoke and dust inside the purification chamber 13. The water mist comes into full contact with the harmful gases and fine particles in the smoke and dust, further purifying the smoke and dust and reducing the harmful components in the smoke and dust. The water mist is discharged through the exhaust pipe on one side of the purification chamber 13. The wastewater generated during the water mist purification process is discharged through the drain pipe on one side of the purification chamber 13 for subsequent wastewater treatment. When it is necessary to clean or replace the primary filter plate 11 and the secondary filter plate 12, pulling the pull block will move the connecting shaft 803. The connecting shaft 803 will pull the pull plate 801 to slide in the placement groove. At this time, the spring 804 is compressed. The two sets of inclined rods 802 that slide against the inside of the plate 801 are gradually pulled out from inside the primary filter plate 11 and the secondary filter plate 12 as the pull plate 801 moves. This facilitates disassembly, allowing operators to clean or replace them. After cleaning or replacement, the primary filter plate 11 and the secondary filter plate 12 are slid back into the purification box 13. The pull block is released, and under the elastic force of the spring 804, the pull plate 801 returns to its original position, and the inclined rods 802 are reinserted into the primary filter plate 11 and the secondary filter plate 12, completing the installation and fixing of the filter plates. The box door 15 can then be rotated and opened, facilitating maintenance and operation of the inside of the purification box 13 by the operators.
