Description

Technical Field

[0001] The invention belongs to the technical field of smoke treatment, and in particular relates to a smoke treatment device for laser cutting of steel structures. Background Art

[0002] Laser cutting is a technology that uses high-energy laser beams to cut materials. It is widely used in the processing of various materials such as metals, plastics, wood, and cloth. Laser cutting has the advantages of high precision, high speed, and high efficiency, and is suitable for cutting complex shapes. The laser cutting machine will produce smoke during the cutting process, and the smoke contains Fe2O3, SiO2, MnO, TiO2, etc. Among them, Fe2O3 has the highest content, generally accounting for 35.56% of the total smoke, followed by SiO2, which accounts for 10-20%, and MnO accounts for about 5-20%. The smoke contains manganese compounds, and long-term inhalation of manganese compounds can cause chronic manganese poisoning, causing organ lesions such as the nervous system, lungs, liver, and blood. Other metal oxides, such as chromium oxide, can accumulate in the body, causing headaches, digestive organ diseases, and anemia. Long-term contact with SiO2 and TiO2 causes silicosis or pneumoconiosis.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) During operation, the smoke treatment device has an alternating filtering structure and an automatic cleaning function by providing a filter box, a cleaning box, a first fan, a smoking pipe, a honeycomb activated carbon box, a second fan, an exhaust pipe, a rectangular frame slot, a rectangular movable frame, a filter, a cleaning structure and a drawer. The alternating filtering structure effectively ensures that the device can continuously filter the smoke, and the automatic cleaning function can effectively clean the replaced filter structure, so that the filter can effectively filter the smoke generated by laser cutting. The alternating filtering and automatic cleaning effectively improve the efficiency and quality of the device in treating the smoke;

[0014] (2) By starting the electric telescopic rod to extend, the short vertical tooth plate is pushed downward, and the downward movement of the short vertical tooth plate will drive the first gear to rotate. The rotation of the first gear can effectively drive the two first connecting shafts to rotate through the two sprockets and the chain, so that the two first connecting shafts drive the filter screen thereon to rotate and adjust the filter screen to a vertical state. The filter screen in the vertical state can make the particulate matter filtered on the surface fall into the inside of the drawer;

[0015] (3) The large disc is rotated by starting the first forward and reverse motor, and the rotation of the large disc drives the arc-shaped rack to rotate. The rotation of the arc-shaped rack will first mesh with one of the fourth gears to drive the rotation. The rotation of one of the fourth gears will drive one of the second connecting shafts and one of the third gears to rotate. The rotation of one of the third gears will drive one of the horizontal long racks to move. The movement of one of the horizontal long racks will drive one of the rectangular moving frames inside the cleaning box to slide on the surface of the sliding rod and move to the inside of the filter box, so that one of the rectangular moving frames and the two filter screens inside it are spliced ​​into a large filter screen structure and moved to the inside of the cleaning box for interception and filtration. After that, the arc-shaped rack will be separated from one of the fourth gears;

[0016] The movement of one of the rectangular moving frames will drive the sleeve, T-pin, conical plug, spring and toggle pin thereon to move, so that the toggle pin is separated from the baffle plate at the same height as the toggle pin, and then the elastic restoring force of the spring will cause the T-pin to drive the conical plug to move toward the second gear and get stuck on the second gear, so that the second gear is limited and fixed, so that the two filter screens inside one of the rectangular moving frames can be stably in a horizontal state, so that the two filter screens can be spliced ​​into a large filter screen structure that can stably filter inside the cleaning box;

[0017] (4) As the arc-shaped rack continues to rotate, the arc-shaped rack will mesh with another fourth gear and transmit the rotation thereof, wherein the rotation of the other fourth gear will drive another second connecting shaft and another third gear to rotate, wherein the rotation of the other third gear will transmit the movement of another horizontal long rack, wherein the movement of the other horizontal long rack will drive another rectangular moving frame located inside the filter box to slide on the surface of the slide rod and move to the inside of the cleaning box, thereby causing another rectangular moving frame and two horizontal filter screens inside it to move to the inside of the cleaning box;

[0018] At this time, the two rectangular moving frames are replaced alternately, so that the filter box can continuously filter smoke and dust; and the other rectangular moving frame moves to the interior of the cleaning box, driving the first gear on it to move toward the short vertical tooth plate aligned with it and mesh with it, and driving the toggle pin on it to move toward the baffle plate aligned with it, so that the baffle plate blocks the toggle pin and drives the T-shaped pin to be inserted into the interior of the sleeve to compress the spring, and at the same time separates the conical plug from the second gear;

[0019] (5) When the filter is adjusted to a vertical state, and the two vertical filters are respectively located between the two pairs of cleaning brushes, the second forward and reverse motor is started to make the rotating rod drive the two pairs of cleaning brushes to rotate. The rotation of the cleaning brush can clean both sides of the vertical filter. By adjusting the positions of both sides of the filter, the cleaning brush can comprehensively and effectively clean the surface of the filter, and the cleaned particulate matter falls into the inside of the drawer for collection.
