DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution for an automobile parts welding workbench: an automobile parts welding workbench, comprising a bottom plate 1, a welding device 2 fixed to the top of the left end of the bottom plate 1, a purification tank 4 is fixedly connected to the top of the bottom plate 1 away from the welding device 2, the purification tank 4 is filled with purification liquid 5, and a fume hood 3 is provided on the side of the welding device 2 close to the purification tank 4;

[0024] refer to Figure 3 and Figure 4 As shown, in order to absorb and purify the smoke generated by welding of automobile parts, the following settings are made: a smoking assembly 6 is provided on the top of the purification tank 4, and when the smoking assembly 6 is started, negative pressure is provided for the smoking hood 3. The smoking assembly 6 includes an air pump 61, and a stabilizing frame 10 is fixedly connected to the top of the bottom plate 1. The air pump 61 is fixed to the inner wall of the stabilizing frame 10. The air suction end of the air pump 61 is fixedly connected to the inside of the smoking hood 3, and the air outlet end of the air pump 61 is rotatably connected to the air transfer pipe 62. When the air pump 61 is started, negative pressure is generated at the smoking hood 3, and the smoke is transmitted to the purification tank 4 through the air transfer pipe 62;

[0025] Furthermore, the bottom end of the air transfer pipe 62 penetrates the inner wall of the purification tank 4 and extends to the inside of the purification tank 4. The bottom end of the air transfer pipe 62 is fixedly connected to a hollow flow plate 63. The peripheral surface of the hollow flow plate 63 is fixedly connected to a plurality of airflow direction plates 64. The flue gas entering the purification tank 4 is diffused through the hollow flow plate 63, and the flow direction of the flue gas is changed according to the different directions of the airflow direction plates 64, so that the flue gas is evenly contacted with the purification liquid 5, which can effectively remove smoke and some oxides, and also has a certain removal effect on some volatile organic compounds.

[0026] Furthermore, a plurality of one-way exhaust pipes 65 are fixedly connected to the interior of the plurality of airflow direction plates 64, and the end surfaces of the plurality of one-way exhaust pipes 65 are connected to the interior of the hollow flow plate 63, and the flue gas with changed flow direction is ejected through the plurality of one-way exhaust pipes 65 respectively.

[0027] Furthermore, the circumference of the purification tank 4 is fixedly connected with an exhaust pipe 8, and an activated carbon filter 9 is fixedly installed on the inner wall of the exhaust pipe 8 by a buckle. The flue gas after particle removal floats upward and is discharged through the exhaust pipe 8.

The driving mechanism 7 includes a motor 71. The motor 71 is fixed to the side of the top of the stabilizing frame 10. The outer wall of the output end of the motor 71 is fixedly connected with a right gear 72, and the right gear 72 is meshed with a left gear 73. The air transfer tube 62 is fixed to the inner wall of the left gear 73. The motor 71 is started so that the output end drives the right gear 72 to rotate and mesh with the left gear 73, so that the air transfer tube 62 rotates and drives the hollow flow plate 63 and a plurality of airflow plates 64 in different directions to rotate, so that the flue gas rotates and sprays out to contact the purification liquid 5 evenly, which can improve the purification efficiency, evenly distribute the purification liquid, increase the contact time and reduce the pressure drop. These advantages are helpful to improve the flue gas purification process and improve the purification effect.

[0029] The working principle and use process of the utility model are as follows: the purification liquid 5 is poured into the purification tank 4 to a depth of one-half of the purification tank 4, and the welding device 2 (the specific working process is consistent with the publication number CN206356786U) starts to weld the automobile parts. The smoke generated during welding is absorbed into the purification tank 4 through the fume hood 3, and the motor 71 is started to make the air transmission tube 62 drive the hollow flow plate 63 and a plurality of air flow plates 64 in different directions to rotate, so that the absorbed smoke rotates and is ejected from a plurality of one-way exhaust pipes 65 to uniformly contact with the purification liquid 5. The smoke purified by the purification liquid 5 is purified again through the activated carbon filter 9 during the process of being discharged through the exhaust pipe 8, thereby removing the volatile organic compounds in the smoke of parts welding, and further improving the quality of smoke purification.
