Description

Technical Field

[0001] The utility model relates to the technical field of workshop dust removal, in particular to a workshop dust removal extension component and a workshop dust removal device. Background Art

[0002] The welding workshop is an important part of the metal processing and manufacturing industry. It is used to perform various welding operations. A large amount of metal smoke and harmful gases will be generated during the welding process. Long-term inhalation of these substances may have serious effects on the workers' respiratory system and health. The welding workshop will produce some debris and particulate matter during welding operations. These mainly include: metal debris, welding slag, and wear particles.

[0003] The dust removal equipment in the welding workshop is installed above the welding station. The dust removal device is connected to multiple workstations in the workshop through exhaust ducts. The exhaust duct branches located at the workshop workstations are installed with exhaust hoods. In order to prevent the dust removal equipment from interfering with the welding process during operation, a certain distance is left between the exhaust hood and the workshop workbench.

[0004] Traditional dust removal devices can collect dust dispersed in the air, but some metal debris will be generated during the welding process in the workshop. This metal debris has a higher density than particles such as smoke, and it is difficult for the exhaust hood at a long distance to collect some of the metal debris generated by welding. Utility Model Content

[0005] Aiming at the defect that the dust removal tools in the prior art are difficult to clean the metal debris, the utility model provides a workshop dust removal extension assembly, which can achieve the effect of cleaning the metal debris.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A workshop dust removal extension assembly comprises an air suction hood for dust and debris adsorption, a first baffle and a second baffle parallel to each other are arranged below the air suction hood, and a plastic sheet foldable in the width direction is arranged between the first baffle and the second baffle in the height direction;

[0008] The second partition slides along the width direction of the plastic sheet, and after sliding, the second partition can form a flow channel for air circulation through the plastic sheet with the first partition.

[0009] A closed flow channel is formed by the first baffle, the second baffle and the plastic cloth of the utility model, and the suction hood generates negative pressure inside the flow channel. This negative pressure will spread along the flow channel, thereby generating suction at the lower end of the flow channel to collect metal debris on the workbench in the welding workshop, thereby improving the device's ability to collect metal debris.

[0010] Among them, the second partition is pushed back to its original position, and the first partition and the second partition are folded and stored, which does not affect the normal welding operation in the workshop and improves the convenience of the actual use process of the device.

[0011] Among them, after the first partition and the second partition are folded and stored, a single-sided barrier is formed, which can block particulate matter such as smoke and dust floating towards the first partition, reduce the dispersion width of particulate matter such as smoke and dust, and improve the collection effect of the device on smoke and dust particles.

[0012] Preferably, a T-shaped groove is provided on the lower surface of the air suction hood, and the T-shaped groove extends along the width direction of the air suction hood.

[0013] In the utility model, the first partition plate and the second partition plate are directly installed on the lower part of the suction hood through the T-shaped groove, thereby improving the convenience of device installation.

[0014] Preferably, the upper ends of the first partition and the second partition are arranged inside the T-shaped groove, and the second partition slides inside the T-shaped groove.

[0015] In the utility model, through the setting of the T-shaped groove, the second partition slides inside the T-shaped groove, and pushing the second partition can quickly change the distance between the second partition and the first partition, thereby realizing rapid extension and storage of the device and improving the convenience of device operation.

[0016] Preferably, the first partition plate and the second partition plate are both made of phenolic foam.

[0017] In the utility model, the phenolic foam itself is relatively light, thus reducing the burden on the suction hood caused by the weight of the first partition plate and the second partition plate.

[0018] Preferably, an L-shaped plate is threadedly connected to the plastic sheet at the connection between the first partition and the second partition, and the inner wall bending part of the L-shaped plate is pressed against the edge of the plastic sheet.

[0019] In the utility model, the L-shaped plate is provided, and the L-shaped plate can compress the plastic sheet at the adhesion part, thereby improving the stability of fixing the plastic sheet to the first partition plate and the second partition plate.

[0020] Preferably, an L-shaped block is fixedly connected to the upper portion of the L-shaped plate outside the first partition, and the L-shaped block is fixedly connected to the corner of the lower surface of the suction hood.

[0021] In the utility model, the position of the first partition is fixed by setting the L-shaped block to prevent the traction force generated by the suction hood during the collection process from pulling the first partition toward the center of the suction hood, causing the flow channel to become smaller, thereby improving the stability of the device during the suction process.

[0022] Preferably, a first square groove is provided on the outer side of the second partition plate, a limit plate is slidably connected to the interior of the first square groove in the height direction, a limit groove extending along the length direction is provided on the lower surface of the air hood, and the limit plate is plugged into the limit groove.

[0023] In the utility model, the second partition plate is fixed to the suction hood by setting a limit plate, so as to prevent the traction force generated by the suction hood during the collection process from pulling the second partition plate toward the center of the suction hood, thereby further improving the stability of the device operation.

[0024] Preferably, second square grooves are provided on both sides of the outer wall of the limiting plate, a flip plate is rotatably connected inside the second square groove, a receiving groove is provided on one side of the second partition plate close to the second square groove, and the flip plate is rotatably engaged with the receiving groove.

[0025] In the utility model, the turning plate is arranged so that the turning plate is engaged with the receiving groove, thereby preventing the limiting plate from falling and improving the stability of the limiting plate in the limiting groove.

[0026] Preferably, the flip plate is provided with a taking slot extending along the length direction.

[0027] In the utility model, by setting the taking groove, a person pushes the limit plate by hand through the taking groove, and the taking groove facilitates the staff to apply force in the subsequent limiting process, thereby improving the comfort of device operation.

[0028] In addition, the utility model also provides a workshop dust removal device, including a dust collector, a ventilation duct is arranged at the dust collector, and the above-mentioned workshop dust removal extension assembly is arranged at the branch of the ventilation duct.

[0029] The dust collector provides suction and removes dust at each workstation through the ventilation duct. The dust removal extension component of the workshop is used to clean metal debris at multiple workstations, thereby improving the overall cleanliness of the welding workshop.
