AI Technical Summary

Technical Problem

When handling dusty or small-particle materials, existing mixers are prone to remove the stirred material together with the dust, waste materials, and dust will float out when the bagged materials are put into it, which cannot be effectively treated.

Method used

A dust-free feeding device including feeding barrels, telescopic cylinders, closure blocks, feeding components and feeding dust removal components is designed. Through the cooperation of outer pipes, inner pipes, pushing cylinders and vacuum cleaners, effective dust-sucking and dust-free input of materials is achieved.

Benefits of technology

It realizes effective removal of dust during the feeding process, avoids material waste and dust floating out, and improves the utilization efficiency of materials and the cleanliness of the working environment.

Abstract

The utility model relates to the technical field of mixing machine feeding, and provides a mixing machine dust-free feeding device for fireproof coating production, which comprises a feeding barrel, a telescopic cylinder and a sealing block, the telescopic cylinder is mounted at the top in the feeding barrel, the sealing block is connected to the output end of the telescopic cylinder, and a feeding assembly is arranged at the top of the feeding barrel. The feeding dust removal assembly is arranged at the bottom of the feeding barrel and comprises an outer pipeline, the outer pipeline is arranged at the bottom of the feeding barrel, an inner pipeline is arranged at the bottom of the feeding barrel, and the inner diameter of the inner pipeline is the same as that of an opening in the bottom of the feeding barrel. According to the technical scheme, the problems that in the related technology, when stirred materials are too small or are in a dust state, the device easily removes the stirred materials together with dust, materials are wasted, feeding is inconvenient, and bagged materials can blow out dust when being put into a storage box and cannot be treated are solved.
