Description

Technical Field

[0001] The utility model relates to the technical field of fume collection, in particular to a fume collection mechanism and argon arc welding equipment thereof. Background Art

[0002] The working principle of argon arc welding equipment is based on the principle of arc welding. It uses the high temperature energy of the arc to heat the material to be welded to a molten state, and then uses argon gas as a shielding gas to isolate the molten welding material and the welding part to prevent it from reacting with oxygen, water vapor, etc. in the air. Smoke will be generated during the operation. In order to protect the working environment and the health of the operators, the argon arc welding equipment will be equipped with a smoke collection mechanism for use.

[0003] In the prior art, the fume collection mechanism on the argon arc welding equipment generally consists of a container that can generate negative pressure, a pipe for transmitting the fume, and a dust collecting component for capturing particulate matter and smoke in the fume. The fume is transported from the pipe to the dust collecting component installed in the container through the negative pressure to filter the particulate matter and smoke in the fume, and the filtered gas is discharged from the container.

[0004] When the flue gas comes into contact with the dust collecting component, the particulate matter and smoke in the flue gas will adhere to the dust collecting component. Gradually accumulating will cause the outer wall of the dust collecting component to be blocked and clogged, resulting in a reduction in the effective use area of ​​the dust collecting component and a decrease in the ability to capture smoke and particulate matter. Manual cleaning or replacement will be required, which shortens the usable life of the dust collecting component, increases the frequency of cleaning, and makes it inconvenient to use.

The front opening of the welding smoke recovery box 100 is rotatably connected to a box cover 104, and the box cover 104 can be rotatably opened and closed, which can facilitate the inspection or replacement of the structure in the welding smoke recovery box 100 and is convenient for cleaning. The side wall of the box cover 104 is fixedly connected to a movable seat 105, and the side wall of the welding smoke recovery box 100 is located below the movable seat 105. The static seat 106 is fixedly connected at the position, and the dynamic seat 105 and the static seat 106 are in the same vertical line and are hollow. The dynamic seat 105 rotates with the box cover 104. When the box cover 104 is closed, the dynamic seat 105 moves to the top of the static seat 106. The box cover 104 can be locked by inserting a latch in the hollow position in the same vertical line between the two, so that the box cover 104 cannot be opened, which increases safety.

The welding smoke recovery box 100 is provided with an exhaust fan 300 that generates a negative pressure in the inner cavity of the welding smoke recovery box 100. The exhaust fan 300 is used to exhaust the air in the welding smoke recovery box 100, so that the internal pressure is reduced to generate a negative pressure suction effect, thereby generating a suction effect at the hood head 102 to absorb the smoke generated by welding;

[0021] Furthermore, a cleaning mechanism is provided in the welding smoke recovery box 100 for intermittently beating the outer wall of the dust bag 200. The cleaning mechanism is used to beat the outer wall of the dust bag 200 so that the smoke or particulate matter remaining in the dust bag 200 can fall to the bottom of the inner cavity of the dust bag 200 for storage, thereby maintaining the usable area of ​​the side wall of the dust bag 200, improving the usable time of the dust bag 200 and the filtering effect of the smoke.

A transmission belt 304 is provided between the double-layer driving wheel and the two transmission wheels 303. When the rotating shaft of the exhaust fan 300 is driven to rotate by the motor, the double-layer driving wheel is driven to rotate. The transmission belt 304 is used to drive the two transmission wheels 303 to rotate. One transmission wheel 303 drives the driving gear 302 to rotate, and the other transmission wheel 303 drives the disc 206 to rotate. The driving gear 302 is used to drive the transmission gear 301 to rotate, so that it drives the other disc 206 to rotate in the opposite direction, so that the two discs 206 rotate in opposite directions. In this way, the two discs 206 rotate in opposite directions. Cooperating with the driving rod 207 on the disc 206, intermittent pressing on the bottom of the beating rod 203 can be achieved, thereby achieving an intermittent cleaning structure for the dust bag 200.
