Description

Technical Field

[0001] The utility model relates to the technical field of smoke purification, and more specifically to a mobile welding smoke purification device. Background Art

[0002] Electric welding is a welding method that uses electricity to achieve atomic bonding between the welded parts through heat, pressure, or both, with or without filler materials. The equipment used for electric welding is called a welding machine. Outdoor welding is also necessary in environments with high levels of smoke and dust. During outdoor work, smoke and dust are constantly raised, so purification is necessary to prevent them from interfering with the welding process.

[0003] However, existing smoke purification equipment often adopts the method of dust extraction and filtration, which is difficult or takes a long time to purify the smoke that is constantly raised in the environment. In the face of the continuous smoke, the workers' vision is blocked and the workers' mouths and noses are damaged, making it difficult for them to perform welding work normally. In view of this, we propose a mobile welding smoke purification device. Utility Model Content

[0028] like Figures 1 to 9 As shown, the utility model relates to a mobile welding fume purification device, comprising four lower partitions 1, an upper partition 2 slidably connected to the front end of the lower partition 1, an extension plate 3 slidably connected to both sides of the upper partition 2, and moving wheels 4 installed on both sides of the bottom end of the lower partition 1;

[0029] One side of the two adjacent lower partitions 1 is rotatably connected, and the four lower partitions 1 form a cavity structure with openings at the top and bottom ends. The four upper partitions 2 form an extension part connected to the cavity structure through the extension plates 3 extending on both sides. The four lower partitions 1 are divided into two lower partitions 1 on the outside and two lower partitions 1 on the inside. The rear end of the outer lower partition 1 is fixedly connected to the exhaust fan 5, which is fixed by but not limited to an embedded fixing method, and the exhaust parts of the two exhaust fans 5 are respectively facing the front and rear ends of the lower partition 1; the exhaust part of the exhaust fan 5 facing the front end is provided with a filter 501, and an annular groove 502 is provided in the connection hole between the rear end of the lower partition 1 and the exhaust fan 5, and a plug-in ring 503 is inserted in the annular groove 502. The plug-in ring 503 is fixedly connected to the end of the wind tube 504, and the head end of the wind tube 504 is eccentrically set. The utility model forms a cavity structure by arranging four lower partitions 1, and an extension portion is formed by arranging four upper partitions 2 and matching extension plates 3. The extension portion and the cavity structure form a high space, which is matched with the exhaust fan 5 to complete the purification, thus forming a purified work space. The utility model can create a new space with less smoke and dust in scenes where smoke and dust are constantly flying, thereby facilitating workers to complete electric welding work.

[0030] Furthermore, a wedge-shaped slide 201 is provided at the front end of the lower partition 1 in the vertical direction. A wedge-shaped slide 101 is slidably connected to the wedge-shaped slide 201. The wedge-shaped slide 101 is provided at the rear end of the upper partition 2. By providing the wedge-shaped slide 201 and the wedge-shaped slide 101, the upper partition 2 can move vertically on the lower partition 1 without moving forward or backward or rotating, thereby limiting the direction of movement.

[0031] Furthermore, the grooves B on both sides of the front end of the upper partition 2 are provided with extension rods 202 along the longitudinal direction. The extension rods 202 are slidably connected to extension holes 301, which are provided on one side of the extension plate 3. By providing the extension rods 202 and the extension holes 301, the extension plate 3 can move along the longitudinal direction on the extension rods 202 without moving forward or backward or rotating, thus limiting the movement direction.

[0032] Furthermore, the front end of the lower partition 1 is provided with a spring hole 102, in which a tensioning spring 103 is disposed. The spring hole 102 is connected to a snap rod 104 via the tensioning spring 103, and the front end of the snap rod 104 extends to the front end of the lower partition 1. By providing the tensioning spring 103 and the snap rod 104, the snap rod 104 restricts the movement of the upper partition 2, preventing the upper partition 2 from automatically sliding down after being opened.

[0033] In the embodiment of the present invention, in order to enable the lower partition 1 to be folded together when not in use and optimize its portability, as shown in FIG. Figure 5 and Figure 6The present utility model discloses a specific structure of a lower partition 1. The outer lower partition 1 is rotated to fit the front end of the adjacent inner lower partition 1. The upper partition 2 and the extension plate 3 are arranged in a groove A provided at the front end of the lower partition 1, and the front end of the upper partition 2 and the front end of the lower partition 1 are located in the same plane. A wedge block 6 is provided on one side of the inner lower partition 1 along the short axis direction. The wedge block 6 is slidably connected to a rotating plate 601, and the rotating plate 601 is rotatably connected to another inner lower partition 1. The present utility model provides a rotating plate 601 and a wedge block 6, so that the inner lower partition 1 can be stretched outward after rotation. Each lower partition 1 rotates to 180 degrees along the connection to fit together and fold together. The present utility model can fold the lower partitions 1 together when not in use, thereby improving the portability of the device.

[0034] As another embodiment of the present invention, in order to prevent the edge of the lower partition 1 from automatically expanding when forming the cavity structure, as shown in FIG. Figure 2 and Figure 7 The present invention discloses a specific structure at the edge of the lower partition 1. An adsorption block 7 is fixedly connected to one side of the outer side of the lower partition 1. Two mirror-image inclined surfaces are provided on the two adsorption blocks 7, and the inclined surface is adapted to the other inclined surface after being rotated 90° counterclockwise along the axis. An adsorption magnetic strip 701 is provided on the inclined surface, and an adsorption groove 702 adapted to the adsorption magnetic strip 701 is provided on the other inclined surface. The present invention adsorbs the two lower partitions 1 that are close to each other when closed by providing the adsorption block 7, the adsorption magnetic strip 701 and the adsorption groove 702. The present invention provides an adsorption structure, which can automatically adsorb the edges of the lower partition 1 at the closed position when the lower partition 1 forms a cavity structure, thereby preventing the lower partition 1 from automatically unfolding.

[0035] Working Principle: This embodiment provides a mobile welding fume purification device. When in use, the staff pulls the lower partition 1, and the lower partition 1 moves via the moving wheel 4, so that the four lower partitions 1 form a rectangle. The inclined surfaces of the two adsorption blocks 7 are abutted against each other, and the adsorption magnetic strip 701 is inserted into the adsorption groove 702, adsorbing the adsorption blocks 7, so that the lower partitions 1 are connected to form a cavity structure.

[0036] The staff then pulls the upper partition 2, which moves on the lower partition 1 along the wedge-shaped slide 201 through the wedge-shaped slide groove 101. After the upper partition 2 is pulled to a high position, the buckle rod 104 is no longer blocked, and the tightening spring 103 pushes out the buckle rod 104, blocking the upper partition 2. After the upper partition 2 is fixed, the extension plate 3 is pulled. The extension plate 3 moves along the extension hole 301 through the extension rod 202, so that the extension plate 3 and the upper partition 2 form an extension part of the cavity structure. Since smoke and dust often float at a lower position on the ground, only a small amount of smoke and dust will enter from above at the height of the extension part and the cavity structure;

[0037] By cooperating with the plug-in ring 503 and the ring groove 502, the air tube 504 is plugged into the ventilation hole of the air inlet part of the exhaust fan 5, so that the air flow is deflected through the air tube 504. The exhaust fan 5 on one side draws the air in the cavity structure and the extension part to the outside, and the exhaust fan 5 on the other side draws the external air into the cavity structure and the extension part after filtering the dust through the filter 501, completing the air exchange, thereby purifying the smoke and dust in the cavity structure and the extension part, and creating an environment suitable for electric welding work.

[0038] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
