Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal device for fumes during laser welding. Background Technology

[0002] The welding process of the acid continuous rolling laser welding machine generates a certain amount of fumes. These fumes are absorbed by the dust collector built into the welding machine. After the dust is initially filtered out by the filter screen in the dust collector, the exhaust gas is directly discharged into the factory. As the number of welding operations accumulates, if the filter screen is not cleaned in time, it will become clogged, and the fumes cannot be effectively extracted and discharged, which will seriously affect the light transmittance of the laser welding machine and affect normal welding operations. Utility Model Content

[0003] The purpose of this invention is to provide a fume dust removal device for laser welding machines to solve the problems mentioned in the background art.

[0013] The technical effects and advantages of this utility model are as follows:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The illustrated fume extraction device for laser welding includes a suction hood 1, and further includes:

[0022] Dust removal component 2 is used for dust removal. Dust removal component 2 includes a vent pipe 201 set on the top of the suction protective cover 1. A variable diameter pipe 202 is set on the top of the vent pipe 201. A main interface pipe 203 is set on one side of the variable diameter pipe 202. A main dust removal main pipe 204 of the scale breaking and straightening machine is set on one side of the main interface pipe 203.

[0023] Connection component 3 is used to connect the vent pipe 201 to the intake protective cover 1 and the reducing pipe 202;

[0024] A pipe valve 4 is provided in the middle of the reducing pipe 202. The pipe valve 4 is used to adjust the flow rate of the gas inside the reducing pipe 202. The horizontal longitudinal section of the reducing pipe 202 is set to L-shape. The reducing pipe 202 is used to connect the vent pipe 201 and the main interface pipe 203.

[0025] It should be noted that laser welding machines generate a large amount of fumes and harmful gases during operation, which pose a threat to the health of operators and the long-term operation of the equipment. The exhaust hood 1 is used to absorb the fumes generated during laser welding. The pipe valve 4 is an existing ball valve used to regulate the airflow. The ventilation pipe 201 is an existing telescopic pipe, with its two ends connected to the exhaust hood 1 and the variable diameter pipe 202 respectively through the connecting assembly 3. This allows the telescopic pipe to deform when the exhaust hood 1 moves with the welding, thus avoiding any impact on the welding process. The secondary pipe diameter reduction increases the dust removal air intake pressure. A 300mm diameter main interface pipe 203 is connected to the middle of the main dust removal pipe 204 of the scale breaking and straightening machine to ensure the air intake volume at the inlet. A 100mm diameter variable diameter pipe 202 is connected to the newly added main interface pipe 203 through a diameter reduction. The variable diameter pipe 202 must be directly above the ventilation pipe 201 and vertically connected to ensure the movement of the welding machine.

[0026] Specifically, the connecting component 3 includes a sealing gasket 305 disposed at the connection between the vent pipe 201 and the suction shield 1 and the variable diameter pipe 202. The sealing gasket 305 is used to seal the connection between the vent pipe 201 and the suction shield 1 and the variable diameter pipe 202. Both ends of the vent pipe 201 are fitted with sliding rings 301. A connecting ring 303 is fixedly connected to one side of the sliding ring 301. Multiple connecting rings 303 are respectively fitted at one end of the variable diameter pipe 202 and the suction shield 1. Multiple positioning blocks 306 are fixedly connected to one end of the variable diameter pipe 202 and the suction shield 1. A bolt 304 is threadedly inserted into the middle of the connecting ring 303. One end of the bolt 304 is threadedly inserted into one side of the positioning block 306. Both ends of the sliding ring 301 are fitted with positioning rings 302 for limiting the movement distance of the sliding ring 301. The positioning rings 302 are inserted into the inside of the connecting ring 303.

[0027] It should be noted that the sealing gasket 305 is made of rubber, which will deform when compressed. During use, the deformed sealing gasket 305 seals the connection between the vent pipe 201 and the suction shield 1 and the reducing pipe 202, preventing gas from leaking out from the connection. The sliding ring 301 is slidably sleeved on the vent pipe 201, allowing it to slide on the vent pipe 201. The positioning ring 302 is fixedly sleeved on the end of the vent pipe 201, limiting the movement distance of the sliding ring 301.

[0028] Furthermore, when it is necessary to fix the vent pipe 201 to the suction shield 1 or the reducer pipe 202, first place the sealing gasket 305 at the connection between the vent pipe 201 and the suction shield 1 or the reducer pipe 202, then fit the vent pipe 201 to the suction shield 1 or the reducer pipe 202, then move the position of the sliding ring 301 so that the connecting ring 303 on one side of the sliding ring 301 is fitted onto the outer wall of the positioning block 306, and finally use bolts 304 to fix the connecting ring 303 to the positioning block 306. The vent pipe 201 is fixed between 06, and the position of the positioning ring 302 is clamped and fixed to one end of the intake protective cover 1 or the variable diameter pipe 202 by the fixed position sliding ring 301 and the positioning block 306. The vent pipe 201 is fixed to the intake protective cover 1 or the variable diameter pipe 202 by the fixed position positioning ring 302, and the connection is made by bolt 304 to avoid the vent pipe 201 from separating from the connection between the intake protective cover 1 and the variable diameter pipe 202 after long-term use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
