Description

Technical Field

[0001] The utility model relates to the technical field of mixer feeding, in particular to a dust-free feeding device for a mixer used in the production of fire-retardant coatings. Background Art

[0002] The mixer is composed of a horizontally rotating container and a rotating vertical stirring blade. When the molding material is stirred, the container rotates to the left and the blade rotates to the right. Due to the effect of countercurrent, the movement directions of the particles of the molding material are crossed, and the chances of contact with each other increase. The countercurrent mixer has a small extrusion force on the material, low heat generation, high stirring efficiency, and relatively uniform mixing. Common mixers can be divided into vertical mixers, horizontal mixers, and drum mixers. The existing public patent: CN206454599U provides a dust-proof feeding device for the mixer, which can absorb the raised dust. However, when the stirring material is too small or in dusty form, the device is likely to remove the stirring material together with the dust, which wastes materials and is inconvenient to load. Moreover, when the bagged material is put into the storage box, dust will float out and cannot be handled.

[0003] Therefore, improvements are made to address the above problems. Utility Model Content
