Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a mobile dust removal device. Background Technology

[0002] Industrial welding operations are widely used in the metal processing industry, but they inevitably generate large amounts of high-concentration welding fumes and harmful gases. These pollutants are complex in composition, containing not only inhalable metal particles (such as manganese, chromium, and nickel) but also toxic gases such as ozone, nitrogen oxides, and carbon monoxide. They pose a serious threat to the respiratory systems of workers exposed to these fumes for extended periods, easily inducing various occupational diseases such as pneumoconiosis, metal fume fever, and asthma. Simultaneously, the pervasive fumes significantly reduce visibility in workshops, contaminate equipment surfaces, and deteriorate the overall working environment.

[0003] However, most welding fume purification devices currently in use are fixed in design. This design means the equipment is in a fixed position and can only vacuum the welding points at designated locations. Once the welding points move, effective dust collection becomes impossible. Therefore, when the welding points are far from the suction port or outside the effective capture range of the suction hood, a large amount of harmful fumes cannot be captured in time and escape directly into the workshop air. This severe lack of adaptability directly results in a significant reduction in the efficiency of existing dust removal systems, and the actual purification effect falls far short of the ideal, failing to effectively protect workers' occupational health and safety and making it difficult to maintain a clean production environment. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a mobile dust collection device that can effectively collect fumes and harmful gases generated during welding in a limited space, improve the working environment, and protect the health of workers.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A mobile dust removal device includes a support frame; the support frame includes a left column and a right column respectively disposed on both sides of the welding station along the X direction, a translation mechanism is installed between the left column and the right column, the translation mechanism is disposed along the Y direction, and a fume hood is installed on the translation mechanism;

[0007] The fume hood includes a top and a curtain surrounding the edge of the top. The top and the curtain together form a dust collection area with an opening at the bottom. A drive motor is installed on the left column. The output shaft of the drive motor is connected to the top of the hood through a transmission assembly. One end of the telescopic smoke pipe is fixedly connected to the top of the hood and communicates with the dust collection area. The other end of the telescopic smoke pipe is connected to the dust purifier.

[0008] Preferably, a left crossbeam arranged in the Y direction is installed on the left column, and a right crossbeam arranged in the Y direction is installed on the right column.

[0009] Preferably, the translation mechanism includes a left sliding component and a right sliding component, wherein the left sliding component and the right sliding component have the same structure; both include

[0010] The C-shaped channel steel rails in the left sliding assembly and the right sliding assembly are respectively installed on the left crossbeam and the right crossbeam;

[0011] The roller is mounted on the top of the cover and is located within and adapted to the C-shaped channel steel track. The roller is made of stainless steel.

[0012] Preferably, the dome includes a top frame, the top frame is connected to the rollers, and a top plate is mounted on the top frame.

[0013] Preferably, the transmission assembly includes a gear mounted on the output shaft of the drive motor and a rack mounted on the top of the cover, the rack being arranged along the Y direction, and the gear meshing with the rack.

[0014] Preferably, the drive motor is a sliding door motor, and a set of limit magnets is installed on the rack.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] The mobile dust collection device of this application includes a support frame, which includes a left column and a right column respectively located at the welding station. A translation mechanism is installed between the left column and the right column. The translation mechanism is arranged along the Y direction and a fume hood is installed on the translation mechanism. The fume hood includes a top and a curtain. The top and the curtain together form a dust collection area with an opening at the bottom. A drive motor is installed on the left column. The output shaft of the drive motor is connected to the top of the hood through a transmission assembly. One end of the telescopic smoke pipe is fixedly connected to the top of the hood and communicates with the dust collection area. The other end of the telescopic smoke pipe is connected to a dust purifier.

[0020] When welding is not in use, the fume hood is positioned along the Y-axis to one side of the welding station, without occupying the space above it, facilitating welding operations. When welding begins, the drive motor starts, moving the hood towards the welding station via a transmission assembly to remove dust. Furthermore, if the weld point position changes due to site conditions, the drive motor can move the fume hood along the Y-axis to adjust its position, ensuring dust removal from different weld points within the welding station. This effectively collects fumes and harmful gases generated during welding within a limited space, improving the working environment and protecting worker health. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] like Figures 1 to 4 As shown in the figure, the present invention includes a support frame 1, which includes a left column 11 and a right column 12 disposed on both sides of the welding station 2 along the X direction. A translation mechanism 3 is installed between the left column 11 and the right column 12. The translation mechanism 3 is disposed along the Y direction and a fume hood 4 is installed on the translation mechanism 3.

[0036] The fume hood 4 includes a top 41 and a curtain 42 surrounding the edge of the top 41. The top 41 and the curtain 42 together form a dust collection area with an opening at the bottom. A drive motor 5 is installed on the left column 11. The output shaft of the drive motor 5 is connected to the top 41 through a transmission assembly 6. One end of the telescopic smoke pipe 43 is fixedly connected to the top 41 and communicates with the dust collection area. The other end of the telescopic smoke pipe 43 is connected to the fume purifier 7. The fume purifier 7 is a well-known technology in this field, and its specific structure will not be described in detail here. The fume purifier 7 is used to absorb welding fumes generated at the welding station 2 using negative pressure and perform adsorption filtration to achieve dust removal.

[0037] Preferably, one end of the telescopic smoke pipe 43 is a flared end, which is fixedly connected to the top cover 41 and communicates with the dust collection area.

[0038] In this application, when welding station 2 is not in use, the fume hood 4 is located on one side of welding station 2 along the Y direction, without occupying the space above welding station 2, thus facilitating construction at welding station 2. When welding is being performed at welding station 2, the drive motor 5 starts, driving the top of the hood 41 towards welding station 2 via the transmission assembly 6 to remove dust from welding station 2. Of course, if the position of the welding point changes due to actual site conditions, the drive motor 5 can drive the fume hood 4 to translate along the Y direction, adjusting the position of the fume hood 4, so that dust can be removed from different welding point positions in welding station 2. This effectively collects fumes and harmful gases generated during welding within a limited space, improving the working environment and protecting worker health.

[0039] In this application, a left crossbeam 13 arranged in the Y direction is installed on the left column 11, and a right crossbeam 14 arranged in the Y direction is installed on the right column 12.

[0040] The left crossbeam 13 and right crossbeam 14 are used to connect the translation mechanism 3. Specifically, the translation mechanism 3 includes a left sliding assembly 31 and a right sliding assembly 32. The left sliding assembly 31 and the right sliding assembly 32 have the same structure; both include a C-shaped channel steel rail 311 and a roller 312. The C-shaped channel steel rail 311 in the left sliding assembly 31 and the right sliding assembly 32 is installed on the left crossbeam 13 and the right crossbeam 14, respectively. The roller 312 is installed on the top cover 41, and the roller 312 is located inside and adapted to the C-shaped channel steel rail 311. The roller 312 passes through the opening of the C-shaped channel steel rail 311 and is located inside it. The roller 312 is a stainless steel roller. Alternatively, the left sliding assembly 31 and the right sliding assembly 32 are both slider-rail assemblies, where the rail is installed on the left crossbeam 13 and the right crossbeam 14, and the slider is installed on the top cover 41.

[0041] The canopy 41 includes a top frame 411, which is connected to the rollers 312. A top plate 412 is mounted on the top frame 411. The top plate 412 seals the top of the canopy 41, preventing outside air from entering the telescopic smoke pipe 43 and affecting the dust removal effect.

[0042] In this application, the transmission assembly 6 includes a gear 61 mounted on the output shaft of the drive motor 5 and a rack 62 mounted on the top cover 41. The rack 62 is arranged along the Y direction, and the gear 61 meshes with the rack 62. Preferably, the drive motor 5 is a sliding door motor, and a set of limit magnets (not shown in the figure) is mounted on the rack 62. Alternatively, the drive motor 5 is a servo motor.

[0043] When the drive motor 5 is a sliding door motor, it is adapted to the limit magnet group, which includes an initial limit magnet and a dust removal limit magnet. When dust removal is not performed, the fume hood 4 is located outside the welding station 2, and the sensor on the drive motor 5 corresponds to the initial limit magnet. When welding is performed, the drive motor 5 drives the rack 62 to move, which moves the fume hood 4 to the welding station 2. At this time, the sensor on the drive motor 5 corresponds to the dust removal limit magnet, and the drive motor 5 stops driving.

[0044] Preferably, the welding station 2 includes a welding torch 21 and a welding turntable 22 located below the welding torch 21, with the bottom end of the cover curtain 42 located between the welding torch 21 and the welding turntable 22.

[0045] The curtain 42 includes several flexible curtains 421, which are long strips and are arranged alternately between adjacent flexible curtains 421.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
