Description
Technical Field
[0001] This utility model relates to the field of welding dust removal technology, and in particular to a mobile welding fume filtration and dust removal device. Background Technology
[0002] In industrial production processes, welding operations such as manual welding, electric arc welding, CO2 shielded welding, MAG welding, carbon arc gouging, gas cutting, and special welding generate fumes. To ensure environmental cleanliness and the health of users, it is often necessary to collect and treat the fumes generated during the welding process.
[0003] Currently, an existing welding dust removal device, with publication number CN219943200U, includes an air suction arm. One end of the air suction arm is connected to a movable purification main unit. The purification main unit contains, from top to bottom, a flame arrester, a filter settling chamber, and a clean chamber. The filter settling chamber contains a filter element for capturing particulate dust and a dust hopper for collecting coarse dust. The clean chamber contains an impeller for purifying the gas, and the impeller is connected to a motor. An air outlet is located at the bottom of the clean chamber. The filter settling chamber and the clean chamber are connected by an air duct. Compared with existing technologies, this invention can achieve efficient purification of welding fumes while reducing equipment maintenance costs and facilitating user operation. It also has advantages such as robust structure, long service life, low noise, and small footprint.
[0004] During the implementation of the existing technical solution, at least the following technical problems were found: The existing device uses an air suction arm facing the welding position, working with a fan and motor to perform dust removal. However, the air suction arm of the existing device can only remove dust from one side of the welding position. In the actual welding process, the generated fumes can drift in all directions. Setting the air suction arm on only one side can absorb most of the fumes, but some fumes will still not be filtered and will drift around the welding position. Therefore, the existing device has the problem of poor dust removal effect. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a mobile welding fume filtration and dust removal device, which solves the problem of poor dust removal effect of existing devices.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A portable welding fume filtration and dust removal device includes a filter box, a PLC controller fixedly connected to the top surface of the filter box, four casters fixedly connected to the bottom of the filter box, a first handle fixedly connected to one end of the filter box, an air guiding mechanism on the top of the filter box, two filter cotton elements on the inner side of the filter box, and an exhaust mechanism on the bottom of the filter box away from the first handle. The air guiding mechanism includes an air intake pipe fixedly connected to the top surface of the filter box, a flow divider fixedly connected to the end of the air intake pipe away from the filter box, and three memory tubes fixedly connected to the side of the flow divider plate away from the air intake pipe. The exhaust mechanism includes an exhaust pipe and a fan, the fan fixedly connected to the filter box, the exhaust pipe fixedly connected to the side of the fan away from the filter box, and a bellows tube threadedly connected to the end of the exhaust pipe away from the fan.
[0007] Preferably, the top surface of the filter box has a slot, and a middle partition is fixedly connected to the middle section of the filter box.
[0008] Preferably, a maintenance window is provided on one side of the filter box, and an observation window is fixedly connected to the side of the filter box with the maintenance window. A sealing groove is provided on the top surface of the middle partition near the maintenance window. Multiple filter cotton plates can be placed in the upper half of the filter box above the middle partition to improve filtration efficiency.
[0009] Preferred configuration: A partition plate is slidably connected inside the slot, a second handle is fixedly connected to the top of the partition plate, and rubber sealing strips are detachably connected to the corners of the partition plate by adhesive. The rubber sealing strips can be replaced after they wear out.
[0010] Preferably, the end of the isolation plate away from the second handle is adapted to the sealing groove, and both side walls of the isolation plate are slidably connected to the inner side wall of the filter box.
[0011] Preferably, the surface of the partition plate has two mounting holes, the inner bottom surface of the filter box is fixedly connected to two mating plates, two filter cotton elements are respectively fitted into the inner side of the two mounting holes, and the top of the two filter cotton elements is provided with a sealing ring, which contacts the top surface of the partition plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects: I. This application uses a PLC controller to control the start of the fan. The operation of the fan creates negative pressure in the lower half of the filter box, which in turn causes the air in the upper half of the filter box to flow to the bottom of the middle partition. During this process, the air is filtered by two filter cotton elements. After the filter box generates negative pressure, it draws in outside air through the suction pipe, the diverter plate, and the memory tube. The three memory tubes are oriented towards the sides and above the welding position, respectively, surrounding the welding position. The fumes generated during welding are drawn in by the three memory tubes, filtered by the two filter cotton elements, and discharged from the exhaust pipe and the bellows pipe. This solves the problem of poor dust removal effect of existing devices.
[0013] Second, in this application, the isolation plate can be removed from the sealing groove and slot through the second handle. At this time, the two filter cotton elements are directly exposed to the maintenance window, which makes it convenient to remove and replace the two filter cotton elements, thus making this application easy to replace the filter cotton elements.

[0023] Two mounting holes are provided on the surface of the partition plate 103. Two mating plates are fixedly connected to the inner bottom surface of the filter box 1.
