Description

Technical Field

[0001] This utility model relates to the technical field of welding fume dust removal devices, and in particular to a mobile welding fume dust removal device. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. When a welding fume dust collector is in use, it draws the fumes generated during welding into the machine and filters them through the internal filter cartridges to remove the dust from the welding fumes. Finally, the filtered air is discharged.

[0003] In existing welding fume dust removal devices, dust tends to accumulate in the filter cartridge and easily adheres to the filter screen during prolonged dust removal processes, causing clogging. To overcome these disadvantages, this invention provides a mobile welding fume dust removal device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mobile welding fume removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable welding fume dust removal device, comprising a supporting shell, a base fixedly connected to the bottom end of the supporting shell, a dust collection tank fixedly connected to the upper end of the supporting shell, an air inlet pipe fixedly connected to the side of the dust collection tank, a one-way valve installed inside the air inlet pipe, an air inlet hood fixedly connected to the outer end of the air inlet pipe, a second servo motor fixedly connected to the middle position of the upper end of the supporting shell, a turntable fixedly connected to the output end of the second servo motor through the top of the supporting shell, an annular filter screen fixedly connected to the outer ring of the upper end of the turntable, discharge ports opened on both sides of the upper end of the supporting shell, a sealing plate installed at the lower end of each discharge port, an end cover fixedly connected to the upper end of the dust collection tank, an exhaust assembly installed on the end cover, and a power assembly for driving the sealing plate to rotate on the supporting shell.

[0006] Furthermore, self-locking casters are fixedly connected to the four corners of the bottom of the base, and a material inlet is provided on one side of the bottom of the support housing, with a sealed door inside the material inlet.

[0007] Furthermore, a fixing plate is fixedly connected to one side of the upper end of the support shell, and a brush is fixedly connected to the inner side of the fixing plate.

[0008] Furthermore, the exhaust assembly includes a fixed base and a first servo motor. The fixed base is fixedly connected to both sides of the upper end inside the support housing. The sealing plates are rotatably connected to the corresponding fixed bases respectively. The output end of the first servo motor is fixedly connected to one side of the corresponding sealing plate.

[0009] Furthermore, each of the sealing plates is fixedly connected to a rotating shaft at one end, and the outer end of each rotating shaft is fixedly connected to a gear through the support housing, with the gears meshing with each other.

[0010] Furthermore, the exhaust assembly includes an exhaust fan, an exhaust grille, and a sealing ring. The exhaust fan is fixedly connected to the middle of the end cover. An exhaust grille is fixedly connected to the upper end of the exhaust fan. A protective net is fixedly connected to the bottom end of the exhaust fan. The sealing ring is fixedly connected to the bottom end of the end cover, located outside the exhaust fan. The outer upper end of the annular filter mesh rotates and seals with the inner side of the sealing ring. A controller is fixedly connected to one side of the upper end of the exhaust grille.

[0011] The beneficial effects of this utility model are:

[0012] In use, this movable welding fume dust removal device is easily moved by its self-locking casters. The exhaust assembly draws outside air and welding fumes into the dust collection tank through the air inlet hood and air inlet pipe. After being filtered by the annular filter, the fumes are discharged through the exhaust grille. When dust removal stops, the power assembly drives the sealing plate to rotate, opening the discharge port. The second servo motor then drives the turntable and the annular filter on its upper end to rotate, throwing out the adhering dust through centrifugal force. The brushes can assist in cleaning, allowing the dust to settle into the support housing through the discharge port. Attached Figure Description
