Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device for casting, grinding and polishing. Background Technology

[0002] Grinding and polishing metal castings generates waste gas containing large amounts of dust and harmful gases, severely polluting the environment and affecting worker health. Current technology typically involves installing a gas collection hood above or to the side of the grinding station, using negative pressure to extract dust and ensure the waste gas is captured at its source. However, this method is ineffective when processing large castings, as the waste gas easily disperses, and the hood's coverage is limited, making comprehensive collection difficult. Furthermore, this method requires individual installation at each station, resulting in high costs and complex maintenance. Therefore, a waste gas treatment device with wide coverage and easy maintenance is needed to completely solve the waste gas pollution problem during the casting, grinding, and polishing process.
