Description

Technical Field

[0001] This utility model relates to the field of industrial welding fume purification technology, specifically to an explosion-proof industrial welding fume purification safety device. Background Technology

[0002] Welding is frequently required during the manufacturing of various equipment in industrial plants, generating large amounts of welding fumes.

[0015] 1. This utility model provides an explosion-proof industrial welding fume purification safety device. It employs a combination of a purification chamber, a fume extraction chamber, a fume extraction machine, a fume extraction shell, a fume extraction port, a water tank, and a cooling and adsorption mechanism. By activating the fume extraction machine, external fumes are drawn into the purification chamber through the fume extraction port and filtered by the filtration mechanism.

This improves the safety of the fume purification device and solves the problem that existing welding fume purifiers, due to the high heat of the surrounding air during welding, can heat the internal temperature of the purification chamber after gas is drawn in, potentially causing safety hazards.

When cleaning the dust filtered in the filter mechanism, the filter mechanism is pulled out of the purification box, and then the cleaning component is moved up and down along the surface of the filter element in the filter mechanism, so that the bristles clean the dust on the surface of the filter element. This solves the problem that although the filter element can filter the fumes when they enter the purification box, some dust may adhere to the surface of the filter element with repeated use and is not easy to clean. This achieves the beneficial effect of conveniently cleaning the dust in the filter element. Attached Figure Description

Then, the cooling and adsorption mechanism 8 sprays water from the water tank 7 in a mist form, cooling the gas and adsorbing water-soluble harmful gases.

[0026] like Figure 2 As shown, this utility model provides a technical solution for an explosion-proof industrial welding fume purification safety device: the cooling and adsorption mechanism 8 includes a water pump 81, a water pumping pipe 82, a conveying pipe 83, three diversion pipes 84, and several atomizing nozzles 85.

[0028] like Figure 4As shown, this utility model provides a technical solution for an explosion-proof industrial welding fume purification safety device: the filter mechanism 6 includes a mounting frame 61, a pull-out plate 62, a filter element 63, and an iron sheet 64. The outer wall of the filter element 63 is fixedly connected to the inner wall of the mounting frame 61, the back of the pull-out plate 62 is fixedly connected to the front end of the mounting frame 61, the interior of the cleaning component 9 is disposed on the outer wall of the mounting frame 61, and the surface of the iron sheet 64 is fixedly connected to the back of the pull-out plate 62 near the outer wall of the cleaning component 9. Limiting grooves 610 are respectively opened at the left and right ends of the outer wall of the mounting frame 61. The outer walls at the left and right ends of the mounting frame 61 are slidably connected to the inner walls of two guide rails 105, and the surface of the iron sheet 64 is magnetically connected to the surface of the magnetic suction plate 104. The two ends of the mounting frame 61 are pushed into the purification box 1 along the inner wall of the guide rail 105 until the iron sheet 64 is magnetically fixed to the surface of the magnetic suction plate 104, which facilitates the installation and disassembly of the filter mechanism 6.

[0029] like Figure 5 As shown, this utility model provides a technical solution for an explosion-proof industrial welding fume purification safety device: the cleaning component 9 includes a movable plate 91, several brush bristles 92, a sealing gasket 93, and two sliders 94. The movable plate 91 is U-shaped, and slots 910 are respectively opened at the left and right ends of the inner wall of the movable plate 91. One end of the several brush bristles 92 is fixedly connected to the upper and lower sides of the inner wall of the movable plate 91 at equal intervals. The inner wall of the sealing gasket 93 is fixedly connected to the outer wall of the movable plate 91. One end of the slider 94 is fixedly connected to the inner wall of the slot 910. The interior of the movable plate 91 and the slot 910 is sleeved with the outer wall of the mounting frame 61, and the outer wall of the slider 94 is connected to the limiting slider. The inner wall of the groove 610 is slidably connected, and the movable plate 91 slides along the limiting groove 610 via the slider 94, which limits the movement trajectory of the movable plate 91. The outer wall of the movable plate 91 engages with the inner wall of the mounting port 102, and the outer side of the movable plate 91 is inserted into the mounting port 102, so that the outer surface of the sealing gasket 93 is tightly attached to the inner wall of the mounting port 102, which further increases the sealing between the filter mechanism 6 and the purification box 1. The outer walls of several bristles 92 overlap with the surface of the filter element 63. By sliding the movable plate 91 back and forth along the outside of the mounting bracket 61, the bristles 92 clean the dust adhering to the surface of the filter element 63.

[0030] The working principle of this explosion-proof industrial welding fume purification safety equipment will be explained in detail below.

[0031] like Figure 1-5As shown, during the welding process of various equipment manufacturing parts in an industrial factory, when using this welding fume purification safety equipment to purify the welding fumes generated in the air, firstly, the control panel 12 is connected to an external power source via wires to control the opening and closing of the fume extractor 3, water pump 81, and solenoid valve 11. Controlling the control panel 12 starts the fume extractor 3 and water pump 81, causing external fumes to be drawn into the purification chamber 1 through the fume extraction port 5. The drawn-in fumes are filtered by the filter element 63. Simultaneously, the water pump 81 draws water from the water tank 7 into the delivery pipe 83 through the water extraction pipe 82, and then delivers it into three branch pipes 84. Finally, the water is atomized and sprayed out through the atomizing nozzle 85, thus purifying the fumes inside the purification chamber 1. The gas temperature is cooled to prevent the internal temperature of the purification box 1 from becoming too high and causing a potential explosion. It can also adsorb harmful gases that are dissolved in water. The filtered and adsorbed gas is discharged from the exhaust port 106. The water deposited at the bottom of the purification box 1 is discharged back into the water tank 7 through the return pipe 10 by opening the solenoid valve 11 for reuse. After use, by pulling the pull plate 62, the iron plate 64 is disengaged from the surface of the magnetic plate 104, and the mounting bracket 61 is pulled out from the purification box 1. Then, the brush bristles 92 slide back and forth along the limiting groove 610 through the sliders 94 on both sides, so that the brush bristles 92 clean the dust adhering to the surface of the filter element 63 on the sealing gasket 93, making it easy for the next use.

[0032] The control panel 12, the smoke machine 3, the water pump 81, the atomizing nozzle 85, and the solenoid valve 11 used are all existing products in terms of their specific types and structures. The specific circuit connection structure and control relationship between the control panel 12 and the smoke machine 3, the water pump 81, and the solenoid valve 11 are also existing technologies, and will not be described in detail here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
