Description

Technical Field

[0001] The utility model belongs to the technical field of welding dust collection, and in particular relates to a welding dust collection device. Background Art

[0002] The main health hazards of welding fume include respiratory diseases, metal poisoning, skin and eye irritation, nervous system damage and increased cancer risk. In factories, welders wear masks, goggles and other equipment for protection, but because welding fume spreads easily, the entire workshop is often filled with fume, causing harm to the health of other workers.

[0003] Problems with existing technologies:

[0004] Existing welding dust suction devices often use a fan connected to a dust suction port to directly aim at the welding area for direct dust suction. Although this is direct and effective, when welding requires shielding gas, such as carbon dioxide shielded welding, argon arc welding, etc., the shielding gas will often be sucked away, reducing the shielding gas and thus reducing the quality of the weld. Utility Model Content

[0005] The purpose of the utility model is to provide a dust suction device for welding, which can increase the air flow rate inside the sliding connecting tube when the air pump is started, thereby reducing the pressure inside the sliding connecting tube, and then connect to the outside world through the sliding connecting dust suction device so that the smoke and dust are sucked into the interior of the sliding connecting tube to filter and repel the air.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A welding dust collection device comprises: a welding station, a sliding connecting pipe disposed transversely above the welding station, a suction filter disposed at one end of the sliding connecting pipe, an air pump disposed at the other end of the sliding connecting pipe, a filter purification box disposed on a side of the air pump away from the sliding connecting pipe, and the suction filter, the sliding connecting pipe, the air pump, and the filter purification box being connected by a pipeline;

[0008] A plurality of plug-in interfaces are provided in an array on one side of the sliding connecting tube, and a sliding connecting dust suction device is provided on the outside of the plug-in interface. The sliding connecting dust suction device is detachably and slidably installed on the sliding connecting tube, and the sliding connecting dust suction device includes a connecting slider, and a dust collecting block is fixedly connected to the bottom of the connecting slider. A plug-in handle is provided on one side of the connecting slider, and a connecting column is fixedly connected to one end of the plug-in handle close to the connecting slider. The connecting column is located inside the connecting slider and is slidably installed with it, and the connecting column is plug-connected to the plug-in interface.

[0009] The two sides of the connecting column are fixedly connected with limiting buckles, and the connecting slider is provided with an L-shaped limiting sliding groove at a position corresponding to the limiting buckles.

[0010] The inner side of the sliding connecting tube is fixedly connected to the two sides above the plug interface with sealing disc fixing seats, and the middle position of the two sealing disc fixing seats is fixedly connected to a sealing disc fixing rod, and a rotating sealing disc is rotatably connected to the sealing disc fixing rod.

[0011] The sliding connecting tube is fixedly connected to fixed spring seats at both sides above the rotating sealing disk, and a spring fixing rod is fixedly connected between the two fixed spring seats. A return spring is sleeved on the outer side of the spring fixing rod, and one end of the return spring contacts the inner wall of the sliding connecting tube, and the other end of the return spring contacts the rotating sealing disk.

[0012] One end of the connecting slide block away from the plug-in handle is bolted to a limit plate, and the sliding connecting pipe is located between the connecting slide block and the limit plate.

[0013] The technical effects achieved by this utility model are:

[0014] According to the utility model, when the air pump is used, the air flow rate inside the sliding connecting tube is increased, thereby reducing the pressure inside the sliding connecting tube, and then the sliding connecting dust suction device is used to connect to the outside world so that smoke and dust are sucked into the interior of the sliding connecting tube and filtered and discharged into the air. Due to the speed limit of air flowing through the sliding connecting tube, the suction force of the sliding connecting dust suction device is relatively smooth, which can effectively absorb dust without affecting the use of protective gas.

[0015] The utility model adopts the detachable sliding installation design of the sliding connecting tube and the sliding connecting dust collecting device, so that the number of sliding connecting dust collecting devices can be installed according to the needs, and the installed sliding connecting dust collecting devices can be slid along the sliding connecting tube to the required position to save resources.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0026] like Figure 1 As shown, a dust suction device for welding includes: a welding station 6, a sliding connecting pipe 1 is horizontally arranged above the welding station 6, a suction filter 2 is arranged at one end of the sliding connecting pipe 1, an air pump 4 is arranged at the other end of the sliding connecting pipe 1, and a filter purification box 5 is arranged on the side of the air pump 4 away from the sliding connecting pipe 1, and the suction filter 2, the sliding connecting pipe 1, the air pump 4, and the filter purification box 5 are connected by a pipeline.

[0027] Among them, when shielded gas welding is required, the air pump 4 is started and extended to the suction filter 2 through the sliding connecting pipe 1, and the outside air is sucked into the filter purification box 5 for filtration and discharge. During this period, the gas flow rate inside the sliding connecting pipe 1 increases, which reduces the pressure. At this time, the sliding connecting dust suction device 3 connects the sliding connecting pipe 1 with the air above the welding position of the welding station 6, and the air will smoothly enter the interior of the sliding connecting pipe 1, so that the welding smoke in the welding station 6 is absorbed and the outside air rushes in. This absorption method is gentle and can effectively avoid the impact on the shielding gas.

[0028] Refer to the attached Figure 2 - Figure 5A plurality of plug-in ports 101 are provided on one side of the sliding connecting tube 1. A sliding connecting dust collecting device 3 is provided on the outside of the plug-in port 101. The sliding connecting dust collecting device 3 is detachably installed with the sliding connecting tube 1. The sliding connecting dust collecting device 3 includes a connecting slider 301. A dust collecting block 303 is fixedly connected to the bottom of the connecting slider 301. A plug-in handle 302 is provided on one side of the connecting slider 301. The plug-in handle 302 is fixed near one end of the connecting slider 301. A connecting column 304 is connected, and the connecting column 304 is located inside the connecting slider 301 and is slidably installed with it. The connecting column 304 is plugged into the plug interface 101; the two sides of the connecting column 304 are fixedly connected to the limit buckles 305, and the connecting slider 301 is provided with an L-shaped limit slot 306 at the position corresponding to the limit buckle 305; the end of the connecting slider 301 away from the plug-in handle 302 is bolted to the limit plate, and the sliding connecting tube 1 is located between the connecting slider 301 and the limit plate.

[0029] According to the above structure, when the sliding connected dust suction device 3 needs to be disassembled, the limit plate is removed by rotating the bolt at one end of the connecting slider 301, and the connecting slider 301 is moved away from the sliding connecting tube 1 to achieve disassembly. When the sliding connected dust suction device 3 needs to be moved, it is only necessary to release the connection between the connecting column 304 and the plug interface 101; the dust collecting block 303 is used to receive welding smoke so that it can be more easily sucked into the sliding connecting tube 1.

[0030] Refer to the attached Figure 6 - Figure 7 The inner side of the sliding connecting tube 1 is fixedly connected to the two sides of the upper side corresponding to the plug-in interface 101 with sealing disc fixing seats 104, and the middle position of the two sealing disc fixing seats 104 is fixedly connected to the sealing disc fixing rod 107, and the rotating sealing disc 106 is rotatably connected to the sealing disc fixing rod 107; the sliding connecting tube 1 is fixedly connected to the two sides of the upper side corresponding to the rotating sealing disc 106 with fixed spring seats 102, and a spring fixing rod 105 is fixedly connected between the two fixed spring seats 102, and a return spring 103 is sleeved on the outer side of the spring fixing rod 105, one end of the return spring 103 is in contact with the inner wall of the sliding connecting tube 1, and the other end of the return spring 103 is in contact with the rotating sealing disc 106.

[0031] According to the above structure, when the connecting column 304 is plugged into the plug interface 101, the rotating sealing disk 106 is pushed to rotate along the sealing disk fixing rod 107. At this time, the reset spring 103 is elastically deformed. At this time, the airflow inside the sliding connecting tube 1 is connected to the outside world through the sliding connecting dust collection device 3. When the connection between the connecting column 304 and the plug interface 101 is released, the reset spring 103 returns to its original position and pushes the rotating sealing disk 106 to the position of the plug interface 101 to seal it, thereby preventing the gas in the sliding connecting tube 1 from contacting the outside world.

[0032] The working principle of the present utility model is as follows: when shielded gas welding is required, the air pump 4 is started and extended to the suction filter 2 through the sliding connecting pipe 1, and the outside air is sucked into the filter purification box 5 for filtration and discharge. During this period, the gas flow rate inside the sliding connecting pipe 1 increases, so that the pressure is reduced. At this time, the sliding connecting dust suction device 3 connects the sliding connecting pipe 1 with the air above the welding position of the welding station 6, and the air will smoothly enter the interior of the sliding connecting pipe 1, so that the welding smoke in the welding station 6 is absorbed and the outside air rushes in. This absorption method is gentle and can effectively avoid the impact on the shielding gas.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
