Description

Technical Field

[0001] This utility model relates to the technical field of waste gas cleaning devices, specifically a welding waste gas cleaning device. Background Technology

[0002] The fumes and harmful gases generated during welding contain metal oxides, non-metallic dust, and harmful gases. Long-term inhalation can damage the respiratory, nervous, and cardiovascular systems of workers. Welding exhaust gas cleaning devices can effectively remove these harmful substances, providing workers with a relatively safe and healthy working environment. Welding fumes not only affect workers' health but also interfere with vision, reduce the stability and accuracy of welding operations, and thus affect production efficiency. Welding exhaust gas cleaning devices can reduce the interference of fumes on operations and improve welding quality and production efficiency.

[0003] For example, the welding exhaust gas cleaning device disclosed in the authorization announcement number CN220424907U includes a box, an air inlet pipe symmetrically connected to the box, a drawer inserted into the lower end of the box, a hopper installed on the inner wall of the box, a support frame installed on the top wall of the box, a vibration filter mechanism provided at the lower end of the support frame, a slot provided on the inner wall of the support frame, an activated carbon filter screen inserted into the slot, an air duct provided on the upper surface of the box, a negative pressure fan installed at the air outlet of the air duct, and the air inlet pipe connected to the air hood through a flexible hose;

[0004] Although it achieves the collection of particles accumulated on the filter screen falling into the hopper and then into the drawer for collection, and the activated carbon filter adsorbing harmful gases and then discharging them through the air duct, thus facilitating the collection of welding exhaust dust particles and the adsorption and elimination of harmful gases, by installing the fan hood on the welding end of the industrial robot, it ensures that the position of the fan hood is always relatively fixed relative to the welding point position when the welding end of the industrial robot moves to weld, thereby allowing the fan hood to fully draw in the welding exhaust gas into the box for cleaning and improving the cleaning and purification effect.

[0005] However, this does not solve the problem that existing exhaust gas cleaning devices of this type are generally not conducive to conveniently raising and lowering the suction port to absorb exhaust gas, nor to conveniently adjusting the position of the suction port in multiple stages to absorb exhaust gas, thus affecting the range of exhaust gas absorption and the flexibility of the exhaust gas cleaning device in adjusting the position of the suction port in multiple stages to absorb exhaust gas. Utility Model Content

[0006] The purpose of this utility model is to provide a welding exhaust gas cleaning device to solve the problems mentioned in the background art, such as the inconvenience of raising and lowering the suction port to absorb exhaust gas, the inconvenience of multi-stage rotation adjustment of the position to absorb exhaust gas, which affects the range of exhaust gas absorption and the flexibility of multi-stage rotation adjustment of the position to absorb exhaust gas.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a welding exhaust gas cleaning device, comprising a base plate and a telescopic column. The telescopic column is mounted on the top of the base plate, and four sets of equally spaced wheels are movably mounted on the bottom of the base plate. A telescopic rod is installed inside the telescopic column, extending to the outside of the telescopic column. A filter device is installed on the side wall of the telescopic rod, and a negative pressure fan is installed at the bottom of the filter device. A flexible hose is installed at the top of the filter device. A support block is installed at the end of the telescopic rod away from the filter device. A suction port body is provided outside the support block, and a guide tube is fitted at the top of the suction port body. The guide tube extends to and connects to the side wall of the telescopic rod. The side of the flexible hose away from the filter device is connected to the guide tube. Power motors are symmetrically installed inside the telescopic column. Each output end of the power motor is fitted with a threaded rod, which extends to and is movably connected to the top of the telescopic column. Threaded blocks are fitted onto the surface of each threaded rod, and the threaded rods are threadedly connected to the threaded blocks. A connecting plate is installed at the bottom of the telescopic rod, and the connecting plate is connected to two sets of threaded blocks.

[0008] Preferably, the guide tube has a first arm on its outside and a second arm on its outside.

[0009] Preferably, the second arm is connected to the suction port body, and a servo motor is installed at the top of the support block.

[0010] Preferably, the output end of the servo motor is equipped with a rotating shaft, and the servo motor is connected to the first arm through the rotating shaft.

[0011] Preferably, the rotating shaft is movably connected to the support block, and a bracket is fitted onto the surface of the first arm.

[0012] Preferably, a buckle is installed at the top of the bracket, and the buckle is in contact with the guide tube.

[0013] Preferably, a stepper motor is mounted on the side of the first arm away from the rotation axis, and a support shaft is mounted on the output end of the stepper motor.

[0014] Preferably, the stepper motor is connected to the second arm via a support shaft, and the support shaft is movably connected to the first arm.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the exhaust gas cleaning device not only realizes the convenient lifting and lowering of the dust suction port to absorb exhaust gas, but also facilitates the convenient multi-stage rotation adjustment position to absorb exhaust gas, increases the range of exhaust gas absorption, and improves the flexibility of the exhaust gas cleaning device to absorb exhaust gas through multi-stage rotation adjustment position.

[0016] (1) When using the welding exhaust gas cleaning device, move the exhaust gas cleaning device to the working area. With the support of the bracket, open the buckle and fix the guide pipe. The power motor drives the threaded rod to rotate. The threaded rod drives the threaded block to move. The threaded block drives the connecting plate, telescopic rod, filter device, negative pressure fan, hose, guide pipe, first arm, second arm, and dust suction port body to rise and fall to the required height. Turn on the negative pressure fan to generate suction so that the exhaust gas is sucked into the filter device through the dust suction port body, guide pipe, hose and filter device for filtration. The filtered gas is discharged through the negative pressure fan. This makes it convenient to raise and lower the dust suction port. It realizes the convenient raising and lowering of the dust suction port to absorb exhaust gas, and improves the convenience of the exhaust gas cleaning device to raise and lower the dust suction port to absorb exhaust gas.

[0017] (2) The servo motor drives the rotating shaft to rotate, which in turn drives the first arm, the second arm, and the dust suction port body to rotate. The stepper motor drives the support shaft to rotate, which in turn drives the second arm and the dust suction port body to rotate. This facilitates convenient multi-level rotation adjustment of the position to absorb exhaust gas, and realizes convenient multi-level rotation adjustment of the exhaust gas cleaning device to absorb exhaust gas. This increases the range of exhaust gas absorption and improves the flexibility of the exhaust gas cleaning device to absorb exhaust gas through multi-level rotation adjustment.
