Description

Technical Field

[0001] This utility model belongs to the field of smoke and dust collection technology, and specifically relates to a smoke and dust collection device. Background Technology

[0002] A fume collection device is a piece of equipment used to collect and treat fumes generated during industrial processing and production. It is mainly used to prevent fumes from spreading into the environment, thereby ensuring the green and environmentally friendly nature of industrial processing and production. It is mainly used in welding, laser cutting and grinding processing. In the electric welding process, in order to ensure the safety and environmental protection of the welding process, it is usually necessary to use a fume collection device to collect and purify the welding fumes.

[0003] Currently, common dust collection devices mainly consist of dust collection and conveying pipes, filter elements, negative pressure exhaust systems, and other auxiliary accessories. In practical applications, the negative pressure exhaust system and dust collection and conveying pipes are used to adsorb and guide welding fumes under negative pressure, and then the fumes are discharged after being filtered by the filter element.

[0004] When welding is performed using different welding processes and welding materials, dust of different properties is generated. Different types of filter media are needed to filter the dust for different properties. However, most dust collection devices in the current technology have a single filter element. When different types of dust need to be filtered, the filter element needs to be disassembled and replaced. This process is not only cumbersome and complicated, but also has poor filtration effect, resulting in poor applicability and filtration effect of the dust collection device.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a smoke and dust collection device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 5 As shown, a dust collection device according to one embodiment of the present invention includes: a housing 1, a multi-functional collection and filtration mechanism 2, and a locking and positioning mechanism 3.

[0031] like Figure 1 As shown, multiple sets of evenly distributed omnidirectional casters 101 are fixedly connected to the bottom of the chassis 1. The multiple sets of omnidirectional casters 101 support, limit, and assist in the movement of the chassis 1, improving the convenience of moving the chassis 1.

[0032] Specifically, the 101 omnidirectional casters are commercially available and can be purchased and used directly.

[0033] like Figure 1 As shown, an exhaust screen 102 is fixedly connected to one side of the chassis 1. The filtered air inside the chassis 1 is discharged through the exhaust screen 102.

[0034] like Figure 1 As shown, the multi-functional collection and filtration mechanism 2 is fixedly assembled inside the housing 1. The multi-functional collection and filtration mechanism 2 includes a supporting base 201, which is assembled inside the housing 1. The supporting base 201 serves to limit the assembly of the collection cylinder 202.

[0035] like Figure 1 As shown, a pair of base rods 206 are fixedly mounted below the supporting chassis 201. Each base rod 206 is threadedly connected to a lifting threaded rod 207. One end of the lifting threaded rod 207, located outside the base rod 206, is rotatably connected to a support base 208. The support base 208 is fixedly connected to the bottom surface of the supporting chassis 201. By controlling the extension of the lifting threaded rod 207, the base rods 206, lifting threaded rods 207, and support base 208 can provide adjustable support and limit for the supporting chassis 201.

[0036] like Figures 1 to 3 As shown, a collection cylinder 202 is rotatably mounted above the supporting chassis 201, and a limiting top cylinder 203 is rotatably sleeved above the collection cylinder 202.

[0037] Both the supporting chassis 201 and the limiting top cylinder 203 are provided with a single ventilation hole. This allows the air delivered by the air intake pipe 210 to enter the single filter element 205 through the ventilation hole and then exit through the ventilation hole on the supporting chassis 201.

[0038] like Figure 1 As shown, an exhaust pipe 209 is fixedly connected to the lower part of the supporting chassis 201. The air filtered inside the filter element 205 is discharged through the exhaust pipe 209.

[0039] Specifically, in practical applications, the exhaust pipe 209 can be connected to a negative pressure ventilation system. By continuously exporting air from the exhaust pipe 209 through the negative pressure ventilation system, the guide pipe 211 can continuously collect and guide welding fumes under negative pressure.

[0040] like Figure 1 As shown, an air inlet pipe 210 is fixedly connected to the top of the limiting top cylinder 203. Both the exhaust pipe 209 and the air inlet pipe 210 are connected to the ventilation hole. The air inlet pipe 210 serves to connect the guide pipe 211 and the filter element 205.

[0041] like Figure 5As shown, a guide pipe 211 is fixedly connected to one end of the air intake pipe 210 located outside the casing 1. The guide pipe 211 guides and collects the welding fumes.

[0042] like Figure 1 As shown, an assembly connecting rod 212 is fixedly connected between the limiting top cylinder 203 and the chassis 1. The assembly connecting rod 212 supports and fixes the chassis 1 and the limiting top cylinder 203.

[0043] like Figures 3 to 4 As shown, multiple filter media labels 213 are fixedly connected to the outer side of the collection cylinder 202, and these labels correspond to the filter element 205. This allows for easy observation and judgment of the position of different types of filter media through the multiple labels 213. A marking groove is provided on the side of the limiting top cylinder 203 near the ventilation hole. The position of the filter element 205 is adjusted by the corresponding matching of the marking groove and the filter media labels 213.

[0044] like Figures 1 to 2 As shown, an inner baffle 204 is fixedly connected inside the collection cylinder 202. The inner baffle 204 serves to limit the assembly of multiple filter elements 205. Multiple evenly distributed filter elements 205 are inserted and assembled inside the inner baffle 204. The multiple filter elements 205 are used to collect and limit different types of filter media.

[0045] It is worth noting that the inner stop block 204 has multiple T-shaped assembly holes, and multiple sets of filter elements 205 are evenly distributed in the T-shaped assembly holes. The T-shaped assembly holes are used to limit the assembly of the filter elements 205.

[0046] like Figures 3 to 4 As shown, multiple evenly distributed positioning pins 214 are fixedly connected above each of the multiple T-shaped assembly holes. The positioning pins 214 are used to insert and engage with the filter element 205 to limit the assembly of the filter element 205.

[0047] like Figures 1 to 4 As shown, the locking and positioning mechanism 3 is assembled inside the limiting top cylinder 203. The locking and positioning mechanism 3 includes a positioning rod 301, which is slidably assembled inside the limiting top cylinder 203. The positioning rod 301 cooperates with the locking and positioning hole on the inner stop 204 to limit the rotation of the inner stop 204, ensuring the stability of the connection between the filter element 205 and the air intake pipe 210 and the exhaust pipe 209.

[0048] like Figures 1 to 4 As shown, a return spring 302 is sleeved on the outer side of the positioning rod 301. The positioning rod 301 is supported and reset by the release of the return spring 302.

[0049] The inner stop 204 has multiple locking and positioning holes on its upper surface, each corresponding to the filter element 205. The positioning rod 301 engages with the locking and positioning holes to assist in positioning the limiting top cylinder 203 and the inner stop 204.

[0050] Specifically, a guide limiting hole is provided above the limiting top cylinder 203, and the positioning rod 301 is slidably assembled in the guide limiting hole. The guide limiting hole provides assembly clearance space for the positioning rod 301.

[0051] like Figures 3 to 4 As shown, a limiting ring 303 is fixedly connected to the outer side of the positioning rod 301, and a hole cover 304 is fixedly connected above the guide limiting hole. A return spring 302 is arranged between the limiting ring 303 and the hole cover 304. The limiting ring 303 and the hole cover 304 limit the compression and expansion of the return spring 302.

[0052] like Figures 3 to 4 As shown, a traction ring 305 is fixedly connected to one end of the positioning rod 301 outside the guide limiting hole. The positioning rod 301 is lifted by pulling the traction ring 305.

[0053] In practical use, the chassis 1 is moved to the welding position by the movement of the universal casters 101, and the air inlet of the guide pipe 211 is aligned with the welding position. When it is necessary to collect welding fumes, the air in the exhaust pipe 209 can be continuously extracted by controlling the operation of the negative pressure exhaust system in the chassis 1. This allows the external welding fumes to be transported along the guide pipe 211 and the air inlet pipe 210 to the filter element 205 for filtration. The filtered air can then be discharged along the exhaust pipe 209 and the exhaust screen 102.

[0054] When different types of welding fumes need to be filtered, the casing 1 can be opened, and the positioning rod 301 can be disengaged from the locking positioning hole by pulling the traction ring 305. Then, different filter media can be selected according to the information marked on the filter media label 213. By controlling the rotation of the collection cylinder 202, the exhaust pipe 209 can be connected to the filter element 205 filled with different types of filter media. After the adjustment is completed, the traction ring 305 can be released, and the inner stop block 204 can be locked and positioned by the cooperation of the positioning rod 301 with the locking positioning hole on the inner stop block 204, which ensures the effect of filtering different types of fumes by using different types of filter media.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
