AI Technical Summary

Technical Problem

Traditional paint mixer exhaust gas collection devices, in order to avoid collision between the mixing column and the collection chamber, make it difficult for the collection chamber and the mixing tank to fit tightly together, resulting in exhaust gas leakage, which affects air quality and increases treatment costs.

Method used

A waste gas collection device for a paint mixer was designed, including a collection chamber set on the top surface of the mixer, with mounting holes and a fan on the bottom surface of the collection chamber, and a sliding tube and a rotating ball fitted on the surface of the mixing column. The rotating ball rotates in the sliding groove to ensure that the collection chamber is tightly fitted with the mixing tank, and the height is adjusted by a threaded structure. With the help of a limiting groove and a limiting block, a seal is achieved during the mixing process.

Benefits of technology

It effectively prevents exhaust gas leakage, improves collection efficiency, reduces air pollution and treatment costs, and protects the health of operators.

Abstract

This utility model discloses a waste gas collection device for a paint mixer, relating to the field of paint waste gas collection technology. It includes a mixer with a waste gas collection assembly on its top surface. The assembly includes a collection chamber disposed on the surface of the mixer's stirring column. Multiple mounting holes are provided on the bottom surface of the collection chamber, and a fan is fixedly connected to the inner wall of each hole. A sliding tube is fitted onto the surface of the mixer's stirring column. The waste gas collection assembly allows the collection chamber to be placed on the top surface of the mixing drum, ensuring the inner wall of the mixer is in contact with the upper end of the mixing drum. This improves the tightness between the collection chamber and the mixing drum, preventing excessive waste gas leakage. When the mixer's stirring column rotates, multiple rotating beads adhere to the surface of the stirring column, causing them to rotate within the sliding groove, thus preventing the stirring column from affecting the collection chamber during rotation.
