[0002] The welding fume dust removal system is an industrial environmental protection equipment, which is mainly used to collect and purify the fume generated during welding. This equipment plays a vital role in electric welding operations such as manual arc welding and soldering. It not only protects the working environment, but also helps to protect the health of workers. The main components of the welding fume dust removal system include universal dust suction arms, high temperature resistant dust suction hoses, dust hoods, flame arrester nets, flame retardant high-efficiency filter elements, etc. These components work together to ensure the efficient operation of the equipment. The welding fume dust removal system sucks the welding fume exhaust gas into the air inlet of the equipment through the gravity of the fan. A flame arrester is installed at the air inlet to prevent sparks from entering. After the fume gas enters the settling chamber, the coarse dust falls directly into the ash hopper, and the fine dust is captured on the outer surface by the filter element. The clean gas flows into the clean room after being filtered and purified by the filter element, and is further purified by adsorption by the activated carbon filter before being discharged.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] See also Figure 1-6The present application provides the following technical solutions: an air suction arm for a welding smoke dust removal system, comprising a support arm 15; a hard guide pipe 3 is laid along the extension direction of the support arm 15, one end of the support arm 15 is rotatably connected to a support arm 4 through a rotating support 13, a hard guide pipe 12 is laid along the extension direction of the support arm 4, the end of the hard guide pipe 12 is connected to the end of the hard guide pipe 3 through a flexible bellows 14, the other end of the support arm 4 is connected to a support arm 3 11 through a rotating support 5, a hard guide pipe 3 7 is laid along the extension direction of the support arm 3 11, one end of the hard guide pipe 3 7 is connected to the other end of the hard guide pipe 2 12 through a flexible bellows 2 6, the other end of the hard guide pipe 3 7 is connected to a steel belt bellows 8, and a suction nozzle 9 is installed at the end of the steel belt bellows 8.

[0026] Specifically, the position of the suction nozzle 9 can be conveniently adjusted up and down through the steel belt bellows 8, and the suction nozzle 9 can be moved and adjusted in the horizontal plane by rotating the support arm 2 4 and along the support arm 3 11. The flexible bellows 2 6 and the flexible bellows 1 14 are both high-temperature resistant tubes with steel belts.

[0027] A mechanical support arm is provided inside the steel belt corrugated pipe 8, and two ends of the mechanical support arm are hinged to the hard guide pipe 3 7 and the suction nozzle 9 respectively.

[0028] Specifically, after the steel belt corrugated tube 8 is adjusted to a certain position, it is supported by a mechanical support arm, which can effectively prevent the suction nozzle 9 from being displaced without external force.

[0029] Furthermore, a mounting seat 1 is installed at the other end of the support arm 15 , and an electric-controlled gate valve 2 is installed on the outer side of the hard flow guide tube 3 near the mounting seat 1 .

[0030] Specifically, the suction arm can be installed on the negative pressure pipe network in the workshop through the mounting base 1.

[0031] More specifically, the suction nozzle 9 can be used normally only after the electric-controlled gate valve 2 is opened. When the suction nozzle 9 is not in use, the electric-controlled gate valve 2 is closed to maintain the pressure of the negative pressure pipe network in the workshop, so that other suction arms can have sufficient negative pressure when working.

[0032] Furthermore, the rotating support 1 5 and the rotating support 2 13 are both damping supports, and the damping supports include a stepped rotating platform 51 and an outer cover 52, the stepped rotating platform 51 and the outer cover 52 are respectively connected to two different rotating parts, and the stepped rotating platform 51 and the outer cover 52 are rotatably connected through bearings.

[0033] Specifically, the stepped rotating platform 51 is disposed close to the outer cover 52 , which can effectively increase the friction force when the stepped rotating platform 51 rotates.

[0034] Furthermore, a handle 10 is provided on the outer side of the suction nozzle 9 .

[0035] Specifically, the position of the suction nozzle 9 can be conveniently moved by the handle 10 .

[0036] Furthermore, the mechanical support arm includes a support arm four 16, one end of the support arm four 16 is rotatably connected to the hard guide tube three 7 through a hinge support one, the other end of the support arm four 16 is rotatably connected to the support arm five 18 through a hinge support two 17, and the end of the support arm five 18 is rotatably connected to the suction nozzle 9 through a hinge support three.

[0037] Specifically, when adjusting the suction nozzle 9 up and down, it is sufficient to rotate the support arm four 16 and the support arm five 18. Since the rotating support arm four 16 and the support arm five 18 are hinged through a hinge support, it is convenient to adjust the position of the suction nozzle 9.

[0038] Furthermore, the hinge support 1, hinge support 2 17 and hinge support 3 are all damping hinges, which include a mounting plate 171. Two symmetrically arranged vertical plates 173 are installed on the outer side of the mounting plate 171. A polygonal rotating shaft 172 is rotatably connected between the two vertical plates 173. The end of the polygonal rotating shaft 172 passes through the vertical plate 173 and is connected to a baffle 176. A spring 175 and a friction plate 174 are sleeved on the outer side of the polygonal rotating shaft 172. The two ends of the spring 175 are fixedly connected to the baffle 176 and the friction plate 174 respectively. The outer side of the friction plate 174 is provided with a ring-shaped clip strip, and the outer side of the vertical plate 173 is provided with a radial clip groove 177 corresponding to the clip strip. The polygonal rotating shaft 172 and the mounting plate 171 are respectively connected to two different hinged parts.

[0039] Specifically, after the positions of support arm four 16 and support arm five 18 are adjusted, the damping hinge can fix the positions of support arm four 16 and support arm five 18, and when the card strip is inserted into the radial card slot 177, the rotational torque of the polygonal shaft 172 can be effectively increased.

[0040] When in use: when adjusting the position of the suction nozzle 9 up and down, the handle 10 is held to pull the suction nozzle 9 up and down, and the support arm 4 16 and the support arm 5 18 rotate at this time. After the height adjustment of the suction nozzle 9 is completed, its height is fixed by the hinge support.

[0041] When the suction nozzle 9 is adjusted horizontally, the suction nozzle 9 is pulled by the hand-held handle 10 to move in the horizontal plane, and at this time, the support arm 2 4 and the support arm 3 11 produce relative rotation.

[0042] When the suction arm is working, the suction nozzle 9 is adjusted to a suitable position directly above the welding station, and the electric control gate valve 2 is opened. The negative pressure in the pipeline sucks the smoke generated during the welding process into the negative pressure dust removal equipment.

[0043] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
