Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, specifically to an air purification device for welding. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials, such as metal workpieces, by heating, high temperature or high pressure.

[0003] The welding process generates unpleasant odors, so welding equipment is equipped with corresponding air purification devices to remove these odors. However, most existing purification devices are fixed to the welding equipment, making them inflexible and difficult to reposition. Furthermore, most existing air purification devices can only purify the air and cannot separate the particles generated during welding. This allows particles to enter the air purification device, causing blockages and affecting its normal operation. Therefore, a more comprehensive welding air purification device is needed to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an air purification device for welding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air purification device for welding, comprising a base plate, a longitudinal rod fixedly connected to the left side of the top surface of the base plate, a purification box fixedly connected to the right side of the top surface of the base plate, casters fixedly connected to the four corners of the bottom surface of the base plate, a sliding groove provided on the front of the longitudinal rod, a slider slidably inserted into the sliding groove, a driving structure provided in the sliding groove to allow the slider to move up and down, a horizontally arranged suction pipe fixedly connected to the front of the slider, a folded flexible hose fixedly connected to the right end of the suction pipe, and the folded flexible hose being located away from the suction pipe. One end of the duct is fixedly inserted into the top left side of the purification box. A collection drawer and a plate are movably inserted into the center of the front of the purification box. The collection drawer is located above the plate, and a filter screen capable of intercepting particulate matter is embedded in the bottom of the collection drawer. A frame inside the purification box is fixedly attached to the back of the plate. A placement slot is opened on the top surface of the frame, and an activated carbon filter plate is placed in the placement slot. A fan is fixedly attached to the lower right side of the purification box. An exhaust pipe is fixedly sleeved on the air inlet end of the fan. The end of the exhaust pipe away from the fan is fixedly inserted into the bottom right side of the purification box.

[0006] As a further embodiment of this utility model: the driving structure includes a servo motor and a screw. The servo motor is fixed to the bottom of the inner wall of the slide groove, the screw is fixed to the output end of the servo motor, and the slider is threaded onto the surface of the screw.

[0007] As a further embodiment of this utility model: two limiting grooves are respectively opened on both sides of the inner wall of the purification box, which correspond to the collection drawer and the insert plate respectively. Both sides of the collection drawer and the insert plate are fixedly connected to the limiting blocks located in the corresponding limiting grooves, and the limiting blocks can slide in the limiting grooves.

[0008] As a further embodiment of this utility model: an air-expanding funnel is fixedly sleeved on the left end of the suction pipe.

[0009] As a further embodiment of this utility model, sealing strips are provided at the connection points between the collection drawer and the insert plate and the purification box.

[0010] As a further embodiment of this utility model: handles are fixedly attached to the front of both the collection drawer and the slide.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] This invention is not only highly flexible and easily movable during use, but also separates welding particles while purifying the welding air, preventing particle accumulation within the purification device and ensuring its normal operation. Specifically, the base plate is pushed to the side of the welding equipment using the casters. Then, the servo motor is turned on. When the servo motor rotates forward, the screw rotates forward, causing the slider on its surface to move upward, thus moving the suction pipe upward along with the slider. When the servo motor rotates in the reverse direction, the suction pipe moves downward. The operator adjusts the position of the suction pipe using the servo motor to direct the airflow. The duct is adjusted to be next to the workbench of the welding equipment. Then, the fan is turned on. The fan creates a suction force in the purification chamber through the exhaust duct. This suction force will expel the air in the purification chamber, while fresh air will enter the purification chamber through the intake duct and the folded flexible hose. This fresh air will bring all the welding particles and toxic gases into the purification chamber. The particles will be intercepted by the filter and remain in the collection drawer. The toxic gases will pass through the filter and then be filtered by the activated carbon filter plate. Finally, they will be discharged from the purification chamber by the fan through the exhaust duct. After the purification work is completed, the staff only needs to pull out the collection drawer and the plug plate to dispose of the waste generated during the purification process.

[0013] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

The end of the exhaust pipe 13 away from the fan 12 is fixedly inserted into the bottom right side of the purification box 3.

[0022] In one embodiment of this utility model: the driving structure includes a servo motor 14 and a screw 5. The servo motor 14 is fixed to the bottom of the inner wall of the slide groove 4, the screw 5 is fixed to the output end of the servo motor 14, and the slider 6 is threaded onto the surface of the screw 5. Turning on the servo motor 14 will allow the screw 5 to rotate, and as the screw 5 rotates, the slider 6 will move up and down.

[0023] In one embodiment of this utility model: two limiting grooves 16 are provided on both sides of the inner wall of the purification box 3, which correspond to the collection drawer 10 and the insert plate 11 respectively. Limiting blocks 17 located in the corresponding limiting grooves 16 are fixedly connected to both sides of the collection drawer 10 and the insert plate 11.

[0027] Working principle:

[0028] First, the base plate 1 is pushed to the side of the welding equipment using the casters 15. Then, the servo motor 14 is turned on. When the servo motor 14 rotates in the forward direction, the screw 5 rotates in the forward direction, and the slider 6 on its surface moves upward, causing the suction pipe 7 to move upward along with the slider 6. When the servo motor 14 rotates in the reverse direction, the suction pipe 7 moves downward. The operator adjusts the position of the suction pipe 7 using the servo motor 14, positioning it next to the workbench of the welding equipment. Then, the fan 12 is turned on. The fan 12 generates a suction force in the purification chamber 3 through the exhaust pipe 13. The force will expel the air from the purification chamber 3, while fresh air will enter the purification chamber 3 through the suction pipe 7 and the folded flexible hose 9. This fresh air will bring all the welding particles and toxic gases into the purification chamber 3. The particles will be intercepted by the filter screen 18 and remain in the collection drawer 10. The toxic gases will pass through the filter screen 18 and then be filtered by the activated carbon filter plate 21. Finally, they will be discharged from the purification chamber 3 through the exhaust pipe 13 by the fan 12. After the purification work is completed, the staff only needs to pull out the collection drawer 10 and the insert plate 11 to dispose of the waste generated during purification. At this point, the entire workflow is complete.
