Description

Technical Field

[0001] The utility model relates to the technical field of waste gas recovery, in particular to an exhaust gas collection and treatment device for a sandblasting machine. Background Technique

[0002] A sandblasting machine is a machine that uses compressed air in a pipeline to transport powdery particles (with a diameter of 1 - 4 mm) from one place to another, and the high-speed moving sand grains scour the surface of an object to improve the surface quality of the object. The sandblasting machine uses compressed air as power to form a high-speed jet beam to spray the abrasive at a high speed onto the surface of the workpiece to be processed. Due to the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface obtains a certain cleanliness and different roughness, thereby improving its mechanical properties. The sandblasting machine is particularly suitable for cleaning the rough surfaces of forgings, stampings and machined parts, as well as the pretreatment processes before spraying and electroplating. Due to the different abrasives sprayed by the sandblasting machine, various waste gases are generated. If the organic waste gas does not meet the standards, it cannot be discharged. Therefore, there is a need for an exhaust gas collection and treatment device for a sandblasting machine that can filter and treat the waste gas generated by the sandblasting machine so that the equipment can meet the national use standards.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Embodiment: Refer to Figures 1 - 3, An exhaust gas collection and treatment device for a sandblasting machine, including a main body 1. An air inlet pipe 2 is connected and installed at the top of the main body 1, and support feet 3 are fixedly installed at the bottom of the main body 1. A treatment box 4 is connected and installed at the bottom of the main body 1. A latch is provided at the connection between the bottom of the main body 1 and the treatment box 4, and it is distributed in a circular array. A buckle adapted to the latch is fixedly installed on the outside of the treatment box 4, which is convenient for disassembling, installing and fixing the treatment box 4. A cavity 5 is opened in the main body 1. A connecting seat 6 is connected and installed in the cavity 5, and a gas collection frame 7 is fixedly installed between the connecting seats 6. There are several connecting seats 6, and they are distributed in a circular array. The tops of the connecting seats 6 are all designed in a triangular structure, which can effectively avoid sand and gravel accumulation while supporting the gas collection frame 7. A support plate 8 is connected and installed in the gas collection frame 7. Several ventilation holes are opened in the support plate 8 to facilitate air circulation.
