Description

Technical Field

[0001] This utility model relates to the field of metal products, and in particular to a dust suppression device for metal product processing. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products, etc. With social progress and technological development, metal products are being used more and more widely in various fields of industry, agriculture and people's lives, creating greater and greater value for society.

[0003] Metal products require welding during processing, which generates a large amount of welding fumes containing metal particles. Inhaling these fumes can damage the respiratory tract of workers. Currently, it is not convenient to treat the welding fumes generated during the welding process, causing them to disperse and affecting the processing environment. Therefore, we propose a dust suppression device for metal product processing to solve the above problems. Utility Model Content

A universal tube 12 is fixedly connected to the right side of the vacuum cleaner housing 1. A dust suction hood 9 is fixedly connected to the end of the universal tube 12 away from the vacuum cleaner housing 1. A handle 10 is fixedly connected to the outer surface of the dust suction hood 9. A top cover 8 is hinged to the upper surface of the vacuum cleaner housing 1. A negative pressure fan 4 is fixedly connected to the left side of the vacuum cleaner housing 1. A limit frame 23 is fixedly connected to the inner wall of the vacuum cleaner housing 1. A filter assembly 2 is placed on the upper surface of the limit frame 23. Two limit plates 24 are provided above the filter assembly 2. A connecting rod 21 is movably hinged to the upper surface of each limit plate 24 through a first hinge seat 22. The top end of each connecting rod 21 is connected to a... The second hinge seat 20 is hinged to the bottom surface of the top cover 8. Two tension springs 17 are fixedly connected to the bottom surface of the top cover 8. The bottom end of each tension spring 17 is connected to the outer surface of the connecting rod 21. A cleaning port 19 is provided on the back of the vacuum cleaner housing 1. The movable connecting rod 21 at the bottom of the top cover 8 can limit the filter assembly 2 by the limiting plate 24 at the bottom of the connecting rod 21 and the limiting frame 23. When the negative pressure fan 4 is running, the vacuum cleaner housing 1 generates a negative pressure, which draws the welding fumes from the welding process into the vacuum cleaner housing 1 through the universal tube 12. The filter assembly 2 is installed in the vacuum cleaner housing 1. The filter assembly 2 filters the particles in the welding fumes, thus ensuring the metal product processing environment.

[0023] A handle 6 is fixedly connected to the front of the top cover 8, and a buckle 5 is provided on the front of the vacuum cleaner housing 1. The buckle 5 is fastened to the handle 6. A fixing clamp 11 is fixedly connected to the right side of the vacuum cleaner housing 1. The top cover 8 is easily fixed by the buckle 5 and the handle 6. The top cover 8 can be opened to facilitate cleaning and replacement of the filter assembly 2. The filter assembly 2 includes an activated carbon mesh 201, an air filter element 202, a metal wire mesh 203, and a filter frame 204. The activated carbon mesh 201, the air filter element 202, and the metal wire mesh 203 are all connected to the inner wall of the filter frame 204. The metal wire mesh 203 first contacts the particles in the welding fume, which can prevent the heat in the welding fume from damaging the air filter element 202. The activated carbon mesh 201 and the air filter element 202 are used for secondary filtration to ensure the quality of welding fume purification.

[0024] Two guide rails 15 are fixedly connected to the back of the vacuum cleaner housing 1. A baffle 16 is slidably connected between the two guide rails 15. A slot 14 is provided on the back of the baffle 16. An observation window 3 is provided on the front of the vacuum cleaner housing 1. The two guide rails 15 cooperate with the baffle 16 to facilitate the sliding of the baffle 16 by using the slot 14, thereby facilitating the opening of the cleaning port 19 to clean the inside of the vacuum cleaner housing 1. A handle 7 is fixedly connected to the upper surface of the top cover 8. A brake caster 18 is installed on the bottom of the vacuum cleaner housing 1. The handle 7 facilitates the opening and closing of the top cover 8, and also facilitates the movement of the dust suppression device by cooperating with the brake caster 18. A control switch 13 is installed on the front of the vacuum cleaner housing 1. The control switch 13 is electrically connected to the negative pressure fan 4 through a wire, and the dust suppression device can be easily controlled by the control switch 13.

[0025] The working principle of this utility model is as follows:

[0026] In use, the dust suppression device is first moved to the metal product welding position by the cooperation of the brake caster 18 and the handle 7. Then, the universal tube 12 is released from the fixing clamp 11, and the dust suction hood 9 is adjusted so that the dust suction hood 9 is above the welding position. The dust suppression device is then started. During the welding process, the negative pressure fan 4 is operated to generate a negative pressure effect in the dust collector housing 1, which draws the welding fumes into the dust collector housing 1 through the universal tube 12. The dust collector housing 1 is equipped with a filter assembly 2. The welding fumes are filtered sequentially by the metal wire mesh 203, the air filter element 202, and the activated carbon mesh 201 in the filter assembly 2, thereby filtering out the particles in the welding fumes and ensuring the metal product processing production environment.
