Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, specifically to a mobile welding fume purifier with high-efficiency dust collection device. Background Technology

[0002] Welding fumes are highly complex substances, containing more than 20 elements. The most abundant are iron, calcium, and sodium, followed by silicon, aluminum, manganese, titanium, and copper. The main harmful substances in welding fumes are iron oxide, silicon dioxide, and manganese oxide, with iron oxide being the most abundant, generally accounting for 35.5% of the total fumes. Silicon dioxide accounts for 10%–20%, and manganese oxide accounts for approximately 5%–20%. During metal welding, a large amount of fumes are suspended in the working environment. Inhaling these fumes can seriously affect health, and in severe cases, can lead to chronic manganese poisoning and welder's pneumoconiosis. Therefore, welding fumes pose a significant threat to operators, making welding fume purifiers essential to eliminate this hazard.

[0003] Currently, the suction arm of traditional welding fume purifiers is usually made of a flexible suction tube. However, during normal use, the suction tube has a certain degree of elasticity, making it impossible to accurately aim the suction hood at a specific point for suction, which is inconvenient for users. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency dust collection device for a mobile welding fume purifier, which can solve the problem that the dust collection arm of the traditional welding fume purifier is usually made of a flexible dust collection tube, but during normal use, due to the elasticity of the dust collection tube, it is impossible to accurately aim the dust collection hood at a certain point for dust collection.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mobile welding fume purifier with high-efficiency dust collection device includes a purifier body, a fixed tube connected to the top of the purifier body, a telescopic tube connected to the upper end of the fixed tube, a dust collection tube connected to the front end of the telescopic tube, a dust collection cover detachably connected to the front end of the dust collection tube, an angle adjustment mechanism at the top of the purifier body, and a clamping mechanism at the top of the angle adjustment mechanism for clamping the dust collection tube.

[0007] Preferably, the angle adjustment mechanism includes an inverted L-shaped support base. The upper end of the support base is provided with a threaded rod, one end of which is provided with a handwheel. A threaded sleeve is threadedly connected to the threaded rod, and a sliding sleeve is connected to the lower end of the threaded sleeve. The sliding sleeve is slidably connected to the support base. A guide groove is provided at the lower end of the support base, and a rotating shaft is provided in the guide groove. The two ends of the rotating shaft pass through the two side walls of the sliding sleeve and are connected to adjusting rods. A support rod is rotatably connected to the middle of the two adjusting rods, and the other end of the support rod is rotatably connected to the mounting base. A clamping mechanism is connected to the top of the adjusting rod.

A left clamping arm and a right clamping arm are threadedly connected to the threaded rod. The left clamping arm and the right clamping arm cooperate to clamp the vacuum pipe. A handwheel is provided at one end of the threaded rod.

[0009] Preferably, the front end of the suction pipe and the rear end of the suction hood are connected by a socket joint, and a threaded hole is provided on the front end of the suction pipe, and a positioning hole that mates with the threaded hole is provided on the rear end of the suction hood. The positioning hole and the threaded hole are connected by bolts.

Detailed Implementation

[0019] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0020] like Figures 1 to 2 As shown, this utility model discloses a mobile welding fume purifier with high-efficiency dust collection device, including a purifier body 1. The bottom of the purifier body 1 is equipped with casters 23. A fixed tube 2 is connected to the top of the purifier body 1, and a telescopic tube 3 is connected to the upper end of the fixed tube 2. A suction tube 4 is connected to the front end of the telescopic tube 3, and a dust collection hood 5 is detachably connected to the front end of the suction tube 4. This utility model, by setting the dust collection hood 5 and the suction tube 4 to be detachably connected, facilitates the replacement of dust collection hoods 5 with different diameters, so as to be suitable for adsorbing different fume areas and ensuring dust collection effect. Specifically, the front end of the suction tube 4 and the rear end of the dust collection hood 5 are connected by a socket joint, and a threaded hole 20 is opened on the front wall of the suction tube 4. A positioning hole 21 that mates with the threaded hole 20 is opened on the rear wall of the dust collection hood 5. The positioning hole 21 and the threaded hole 20 are connected by a bolt 22.

[0021] The purifier body 1 is equipped with an angle adjustment mechanism at its top, which allows for adjustment of the angle of the dust hood 5, suitable for dust collection at different heights. The angle adjustment mechanism includes an inverted L-shaped support base 6. A threaded rod 7 is provided on one side of the upper end of the support base 6. A handwheel 8 is provided at one end of the threaded rod 7. A threaded sleeve 9 is threadedly connected to the threaded rod 7. A sliding sleeve 10 is connected to the lower end of the threaded sleeve 9. The sliding sleeve 10 is slidably connected to the support base 6. A guide groove 11 is provided at the lower end of the support base 6. A rotating shaft is provided in the guide groove 11. The two ends of the rotating shaft pass through the two side walls of the sliding sleeve 10 and are connected to adjusting rods 12. A support rod 13 is rotatably connected to the middle of the two adjusting rods 12. The other end of the support rod 13 is rotatably connected to the mounting base 14. During adjustment, rotating the handwheel 8 drives the threaded rod 7 to rotate, causing the threaded sleeve 9 on the threaded rod 7 to move. The threaded sleeve 9 drives the sliding sleeve 10 to slide on the support seat 6, thereby causing the rotating shaft to move in the guide groove 11. Finally, the adjusting rod 12 moves to achieve angle adjustment.

[0022] A clamping mechanism is rotatably connected to the top of the adjusting rod 12. The clamping mechanism is used to clamp the vacuum tube 4 and provide fixed support for the vacuum tube 4. The clamping mechanism includes a base plate 15, and a threaded rod 16 is provided on the top of the base plate 15. A left clamping arm 17 and a right clamping arm 18 are threadedly connected to the threaded rod 16. The left clamping arm 17 and the right clamping arm 18 cooperate to clamp the vacuum tube 4. A handwheel 19 is provided at one end of the threaded rod 16. When clamping, rotating the handwheel 19 drives the threaded rod 16 to rotate, causing the left clamping arm 17 and the right clamping arm 18 on the threaded rod 16 to move towards each other until the vacuum tube 4 is clamped.

[0023] Working principle: When in use, first clamp the suction pipe 4 with the clamping arm of the clamping mechanism, and then adjust the angle of the suction hood according to the welding position. When adjusting, turn the handwheel 8 to drive the threaded rod 7 to rotate, so that the threaded sleeve 9 on the threaded rod 7 moves. The threaded sleeve 9 drives the sliding sleeve 10 to slide on the support seat 6, so that the rotating shaft moves in the guide groove 11. The rotating shaft drives the adjusting rod 12 to move to achieve angle adjustment. After the adjustment is completed, the purifier body 1 can be opened to perform vacuuming.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
