Background technique

Welding, also known as welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heat, high temperature or high pressure; modern welding energy sources are many, including gas flame, arc, laser, electronic beam, friction, and ultrasound. In addition to being used in factories, welding can be performed in a variety of environments, such as in the field, underwater, and in space. Welding can be dangerous to the operator wherever it is, so proper precautions must be taken when welding.

At present, during the welding process, the workers often place the workpieces to be welded on the welding platform for welding operations. However, a large amount of welding fumes are easily generated during the welding process, which will not only affect the vision of the workers, but also lead to inconvenience in welding. Operation, the metal particles and toxic and harmful gases in the welding flue gas will also affect the health of the staff, so a flue gas collection structure will be set next to the welding platform to collect the generated flue gas, but the existing flue gas collection The structure is inconvenient to adjust the height of its flue gas collection. The welding platform varies in height according to the welding habits and height of the workers. However, the existing collection structure is not convenient for the collection operation of the flue gas, and the existing The existing flue gas collection structure simply sucks and discharges the flue gas, and cannot effectively treat the metal particles and toxic and harmful gases in the flue gas, which is easy to cause harm to other workers around. The existing flue gas collection structure In order to prevent small-volume workpieces or large particles of welding slag from falling into the structure, a protective net is often installed at the position where the flue gas enters. However, when the collection structure is used for a long time, the surface of the protective net is easy to adhere to a lot of stains.

A method of using a welding fume collecting structure of a welding platform for processing, characterized in that: the using method comprises the following steps: A: When the height of the flue gas collection needs to be adjusted, the worker first moves the structure to one side of the welding platform, and then the worker turns on the biaxial motor (131), so that the front and rear sides of the biaxial motor (131) are turned on. The output shaft rotates, which in turn drives the bevel gears (132) on the front and rear sides to rotate, and the bevel gears (132) mesh with the gear disc (133), so that the gear disc (133) drives the threaded rod (14) to rotate. , the threaded rods (14) on the front and rear sides rotate in the same direction, and the limit block (28) limits the sleeve (15), so that the sleeve (15) moves up and down on the threaded rod (14), The staff controls the rotation direction of the output shaft of the biaxial motor (131) according to the height of the welding platform, so that the sleeve (15) pushes the upper connecting plate (16) to move up and down, and adjusts the height of the collection cover (2). , so that the collection cover (2) and the table top of the welding platform are kept horizontal, so as to complete the operation of adjusting the height of the flue gas collection; B: The worker turns on the air pump (12) before welding. When the worker is welding, the collecting hood (2) directly inhales the flue gas generated during welding, and the gas enters the first ventilation pipe (17) into the first Inside a process box (18), after the gas enters, the first motor (191) and the electromagnet (22) are turned on at the same time, so that the output shaft of the first motor (191) drives the rotating rod (192) to rotate, stirring the plate (193) stirs the incoming gas to make the gas contact the surface of the adsorption cover (20) as much as possible, the electromagnet (22) enables the adsorption cover (20) to adsorb the metal particles in the gas, and the gas and the adsorption cover (20) can adsorb the metal particles in the gas. After the adsorption cover (20) is in contact, the metal particles inside it are effectively treated, and then enter the inside of the second processing box (24) through the second ventilation pipe (23), and the dust and toxic and harmful gases in the gas pass through the activated carbon filter layer (252). ), the photocatalyst filter layer (253) and the filter screen (254) after multiple filtration and purification, are discharged from the exhaust pipe (26), so as to complete the filtering operation of the welding fume; C: When the structure has been used for too long and a lot of stains are attached to the surface of the protective net, the staff first presses the picks (9) on both sides to move the picks (9) toward each other, and the picks (9) follow the It drives the movable piece (71) inside the cavity (6) to move, and squeezes the spring (72), the fixing rod (73) moves out from the fixing hole (74) of the upper block (4), and then works The personnel pushes the clamping block (4), so that the clamping block (4) is removed from the interior of the clamping slot (5), and then the entire fixing frame (3) is removed. After cleaning, the staff presses the movable pieces (71) on both sides again, and puts the fixing frame (3) into the collecting cover (2) again, and the clamping block (4) enters the clamping slot (5). Inside, then the staff releases the paddle (9), so that the spring (72) rebounds, and pushes out the fixing rod (73), so that the fixing rod (73) enters the fixing hole (74) again, so as to complete Disassembly and assembly of the protective net and cleaning operations.
