Description

Technical Field

[0001] This utility model relates to the field of argon arc welding machine fume purification, specifically to a fume purification device for argon arc welding machines. Background Technology

[0002] Argon arc welding machines are machines that use argon arc welding, employing a high-pressure breakdown arc initiation method. Argon arc welding, also known as tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as a non-consumable electrode and inert gas as a protective layer. The contact tip conducts electricity, generating an electric arc between the base material and the welding wire, melting the welding wire and the base material. The arc and molten metal are protected by inert argon gas for welding.

[0003] A search revealed a utility model patent with publication number CN218904068U, which discloses a welding machine fume purification device. The device includes a welding machine body, a welding clamp with a protective cover on its outer side, and a purification box fixedly installed on the top of the welding machine body. The device works by activating an exhaust fan to extract welding fumes, which are then transported through a pipe to the purification box. Inside the purification box, activated carbon filter cotton, honeycomb activated carbon, and a high-efficiency air filter are used to filter the fumes. The filtered gas is then discharged from the outlet, thus achieving fume purification. After a period of use, pulling the handle backward removes the locking block from its slot and pulls the drawer out of the purification box, facilitating the cleaning and replacement of the activated carbon filter cotton, honeycomb activated carbon, and high-efficiency air filter fixedly installed inside the drawer, effectively improving the filtration and purification quality.

[0004] Existing welding machine fume purification devices typically use activated carbon materials to filter the inside of the fume during use. However, activated carbon generally performs adsorption filtration and cannot effectively intercept and filter larger particles. Welding machines generate not only adsorbable harmful gases but also larger particulate impurities. Furthermore, the existing adsorption process generally involves passing the fume through activated carbon materials for adsorption filtration during transport, which greatly reduces the efficiency and quality of filtration.

[0005] Therefore, it is necessary to invent a fume purification device for argon arc welding machines to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a fume purification device for argon arc welding machines. By rotating the drum and the entire machine, the flow guide fan is driven to rotate, which increases the adsorption and filtration area of ​​the graphene material inside and also guides the fume. The annular glass fiber filter element can filter the particles in the fume, and the brush can clean the annular glass fiber filter element during the rotation process, so as to solve the problem of low efficiency and quality of fume filtration in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fume purification device for an argon arc welding machine, comprising a purification tank, an air inlet pipe connected through the top of the purification tank, and multiple sets of exhaust pipes connected through the side of the purification tank.

[0008] The drive assembly installed inside the purification tank includes a connecting cylinder, which is installed above the inner wall of the purification tank, and the through connection of the air inlet pipe is located inside the connecting cylinder. Multiple sets of through holes are arranged in a ring on the inner wall of the connecting cylinder.

[0009] The filter assembly installed inside the purification tank includes two sets of annular glass fiber filter elements. The two sets are installed on the upper part of the inner wall of the purification tank and are arranged concentrically. The surfaces of the two sets of annular glass fiber filter elements are arranged in a ring and have multiple sets of filter holes.

[0010] Preferably, the drive assembly further includes a motor, which is installed below the purification tank. A connecting plate is rotatably connected to the lower inner wall of the purification tank, and the connecting plate is axially connected to the output end of the motor.

[0011] Preferably, a positioning ring is fitted and fixed on the connecting plate, and an annular groove is formed on the inner wall of the purification tank, with the positioning ring slidably connected to the annular groove.

[0012] Preferably, multiple sets of rotating cylinders are installed in a ring on the connecting plate, and multiple sets of through holes are opened on the surface of each set of rotating cylinders, and graphene adsorption material is provided inside the rotating cylinder.

[0013] Preferably, a gear is installed above each set of rotating drums, a toothed ring is installed on the inner wall of the connecting cylinder, and the toothed ring meshes with each set of gears, and a guide turbine fan is installed at the center of the connecting disc.

[0014] Preferably, the filter assembly further includes sealing rings, which are concentrically distributed and sequentially installed above the connecting disc, with each group of sealing rings fitting against the lower edge of the corresponding annular glass fiber filter element. Connecting rods are sequentially installed above the connecting disc, and brushes are symmetrically installed on the connecting rods, with the brushes fitting against the surface of each group of annular glass fiber filter elements.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] The motor drives the connecting disc to rotate, causing the entire rotating drum to rotate while also rotating on its own axis. This increases the adsorption area of ​​the graphene material inside the drum. Simultaneously, the connecting disc moves the brushes across the surface of the annular glass fiber filter element, allowing the filter element to filter larger particles in the smoke and dust while preventing clogging. Furthermore, the guide fan, following the rotation of the connecting disc, guides the flow of smoke and dust. This structure not only enhances the adsorption and filtration effect of the graphene material but also allows the annular glass fiber filter element to filter larger particulate impurities in the smoke and dust. Its mechanical structure also guides the flow of smoke and dust while cleaning its internal structure, preventing clogging and significantly improving the filtration quality and efficiency of the equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The present invention provides a fume purification device for an argon arc welding machine, including a purification tank 001, an air inlet pipe 101 connected through the top of the purification tank 001, and multiple sets of exhaust pipes 102 connected through the side of the purification tank 001.

[0027] The air intake pipe 101 allows smoke and dust to enter the purification tank 001 for purification, and the dust can be discharged through the exhaust pipe 102 after purification is completed.

[0028] The drive assembly 002 installed inside the purification tank 001 includes a connecting cylinder 201. The connecting cylinder 201 is installed above the inner wall of the purification tank 001, and the through connection of the air inlet pipe 101 is located inside the connecting cylinder 201. Multiple sets of through holes 210 are arranged in a ring on the inner wall of the connecting cylinder 201.

[0029] The smoke and dust are sent into the connecting cylinder 201 through the air inlet pipe 101, and finally enter the purification tank 001 through the through hole 21O.

[0030] The filter assembly 003 installed in the purification tank O01 includes two sets of annular glass fiber filter elements 301. The two sets are installed on the upper part of the inner wall of the purification tank 001, and the two sets of annular glass fiber filter elements 301 are arranged concentrically. The surfaces of the two sets of annular glass fiber filter elements 301 are arranged in a ring and each has multiple sets of filter holes 305.

[0031] Larger particles in the smoke and dust can be filtered through the filter holes 305 on the surface of the annular glass fiber filter element 301.

[0032] Furthermore, in the above structure, the drive assembly 002 also includes a motor 202, which is installed below the purification tank 001. A connecting plate 203 is rotatably connected to the lower inner wall of the purification tank 001, and the connecting plate 203 is axially connected to the output end of the motor 202.

[0033] The motor 202 can drive the connecting plate 203 to rotate.

[0034] Furthermore, in the above structure, a positioning ring 204 is fixedly fitted onto the connecting plate 203, and an annular groove 205 is provided on the inner wall of the purification tank 001, with the positioning ring 204 slidably connected to the annular groove 205.

[0035] The connection plate 203 can rotate stably inside the purification tank 001 through the cooperation of the annular groove 205 and the positioning ring 204.

[0036] Furthermore, in the above structure, multiple sets of rotating cylinders 206 are installed in a ring on the connecting disk 203, and multiple sets of through holes 211 are opened on the surface of each set of rotating cylinders 206, and graphene adsorption material is provided inside the rotating cylinder 206.

[0037] Through the through-hole 211 on the surface of the rotating drum 206, smoke and dust can enter the rotating drum 206, and the harmful substances in the smoke and dust are adsorbed by the graphene material inside.

[0038] Furthermore, in the above structure, gears 207 are installed above each set of rotating cylinders 206, and gear rings 208 are installed on the inner wall of the connecting cylinder 201, with the gear rings 208 meshing with each set of gears 207. A guide turbine fan 209 is installed at the center of the connecting disc 203.

[0039] Through the meshing of gear 207 and gear ring 208, the connecting disc 203 can drive the rotating drum 206 to rotate as a whole, while the rotating drum 206 can also rotate independently. Furthermore, the connecting disc 203 can drive the guide fan 209 to rotate, thereby guiding the smoke and dust.

[0040] Furthermore, in the above structure, the filter assembly 003 also includes sealing rings 302. The sealing rings 302 are concentrically distributed and sequentially installed above the connecting plate 203, and each set of sealing rings 302 is in contact with the lower edge of the corresponding annular glass fiber filter element 301. Connecting rods 303 are sequentially installed above the connecting plate 203, and brushes 304 are symmetrically installed on the connecting rods 303, and the brushes 304 are in contact with the surface of each set of annular glass fiber filter elements 301.

[0041] The sealing ring 302 ensures the sealing between each group of annular glass fiber filter elements 301, and the brush 304 can rotate with the connecting disc 203, thereby ensuring the unobstructed flow of the filter holes 305 on the surface of the annular glass fiber filter element 301.

[0042] The working principle of this practical application is as follows:

[0043] Refer to the instruction manual appendix Figure 1-5The motor 202 starts, causing the connecting plate 203 to rotate, which in turn causes the rotating drum 206 to rotate simultaneously. At this time, the intake pipe 101 draws in the smoke and dust, and the guide fan 209 guides the smoke and dust, allowing harmful substances in the smoke and dust to be adsorbed by the graphene material inside the rotating drum 206. Furthermore, the rotation of the graphene material driven by the rotating drum 206 increases the adsorption area, thereby improving the adsorption effect. When the smoke and dust flow through the through-hole 210 into the spaces between the annular glass fiber filter elements 301, larger particles remaining in the smoke and dust can be adsorbed by the annular filter elements. The annular glass fiber filter element 301 filters the air, and due to the rotation of the connecting disc 203, the brush 304 can move along the filter holes 305 on the surface of the annular glass fiber filter element 301, thereby avoiding clogging. This structure not only increases the adsorption and filtration effect of the graphene material, but also allows the annular glass fiber filter element 301 to filter larger particulate impurities in the dust. Furthermore, its mechanical structure can guide the dust while cleaning its interior, preventing internal clogging, thus greatly improving the filtration quality and efficiency of the equipment.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
