Description

Technical Field

[0001] This invention relates to the field of welding fume purification technology, and in particular to an air intake device for a welding fume purifier. Background Technology

[0002] Welding fume purifiers are industrial environmental protection equipment, typically used in welding environments such as soldering and manual arc welding, to collect and purify the welding fumes generated, thereby protecting the environment and the health of workers. Welding fume purifiers can purify a large number of fine metal particles suspended in the air that are harmful to the human body.

[0003] Therefore, the fumes generated during welding need to be collected to prevent workers from inhaling them and causing harm. Existing fume purification methods mostly involve using welding fume purifiers to draw the welding fumes into the purifier, preventing them from remaining in the air and being inhaled, thus avoiding harm. However, existing welding fume purifiers have the following problems: 1. The air intake pipe used in the welding fume purification device cannot be easily adjusted according to the height and position of the welding point, resulting in the air intake pipe failing to capture all the fumes generated during welding; 2. When the air intake pipe of the welding fume purifier is at a low or high position for fume adsorption, it cannot remain fixed at the adsorption position. Because the air intake pipe is mostly a corrugated pipe structure, it cannot maintain stability at the air intake position when the pipe is stretched long. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an air intake device for welding fume purifiers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

By adjusting the height of the sliding plate on the side wall of the collection box and the rotation process of the support rod on the rotating frame, the contact frame can be driven to contact the collection tube, providing contact support for the air inlet end of the collection tube and ensuring the stability of the air intake when the collection tube is at a high position.

[0019] 3. The present invention is provided with a fixed pipe, a mounting bracket, an auxiliary fan and a rotating groove. With the support of the rotating groove and the mounting bracket, the auxiliary fan is directed toward the welding point. By driving the air circulation in the air intake part of the collection pipe, the air intake process in the collection pipe is assisted, which improves the collection efficiency of the smoke generated during the welding process and at the same time prevents the welding smoke from escaping during the welding process.

[0032] Mounting plates 22 are fixedly connected to both the side wall of the filter tube and the inner wall of the collection box 1.

The traction mechanism includes a rotating gear 19 fixedly connected to the side wall of the filter tube.

An electrical control box 17 is fixedly connected to the side wall of the collection box 1 located on the side of the control panel 16. The electrical control box 17 is electrically connected to the control panel 16.

[0035] The functional principle of this invention can be explained through the following operational methods: such as Figure 1-5As shown, during use, the fan 26, connected to the exhaust pipe 25, first connects the air inlet of the fan 26 to the filter pipe and the collection pipe 4. When the collection pipe 4 is located at the fixed pipe 5, a negative pressure is applied to absorb the smoke. During the adjustment of the collection pipe 4, the corresponding adjustment buttons on the control panel 16 control the up-and-down movement of the cylinder 20, which in turn moves the connecting ring 18 up and down, thus moving the collection pipe 4 up and down. At this time, rotating the sliding contact between the base 3 and the sealing base 2 seals the collection box 1. Simultaneously, the filter pipe extends into the collection pipe 4, allowing for welding. The smoke is sealed during the air intake process to prevent the escape of welding fumes. When it is necessary to adjust the position of the collection pipe 4 in the left and right directions, the left and right control buttons on the control panel 16 drive the motor 23 to rotate and rotate in the opposite direction. The motor 23 drives the drive gear 24 to mesh with the rotating gear 19, thereby driving the rotation of the filter pipe. Through the contact of multiple limiting grooves 21 and limiting blocks between the side walls of the filter pipe and the collection pipe 4, the synchronous rotation of the collection pipe 4 and the filter pipe can be achieved. At the same time, under the sliding limiting action of the limiting grooves 21 and the limiting blocks, the up and down movement of the collection pipe 4 on the side wall of the filter pipe can be satisfied.

[0036] During the process of collecting welding fumes generated at the welding point, the mounting bracket 7 located in the rotating groove 6 rotates to adjust the air intake direction of the auxiliary fan 8, guides the fumes near the welding point, and delivers them to the air inlet of the collection pipe 4. This guides the flow of welding fumes and prevents the escape of welding fumes, thus assisting the collection pipe 4 in the process of collecting welding fumes.

[0037] When adjusting the extension length of the collecting tube 4 to correspond to the welding point, rotating the adjusting screw 15 causes the sliding block to move within the adjusting groove 9, thereby adjusting the position of the sliding plate 10. This causes the support rod 13 and contact frame 14 within the rotating frame 12 to abut against the side wall of the collecting tube 4. This provides support for the collecting tube 4 at a relatively high adsorption position, preventing the welding fume collection position from being too high and causing the collecting tube 4 to be unable to support itself, thus preventing the welding fume from escaping from the welding point. Simultaneously, the contact support of the guide rod 11 and contact plate 14, along with the threaded connection between the adjusting screw 15 and the sliding block, keeps the sliding plate 10 and support rod 13 fixed, providing support for the contact frame 14. When the collecting tube 4 is located at... Figure 1 When the tube is positioned close to the front end of the collection box 1, the sliding plate on the side is installed in the adjustment groove 9 located at the front end to adjust the support of the collection tube 4 in different positions and directions.

[0038] When the flue gas passes through the filter tube, it is filtered by the filter cotton core inside, which performs the initial filtration and cleaning of the particulate matter. After long-term use, the filter cotton core inside the filter tube can be removed by disassembling the disassembly plate 27 and then cleaned or replaced.
