Equipment of dry-method sand making process based on sieved materials

Abstract

The invention relates to the technical field of dry-method sand making, and discloses equipment of a dry-method sand making process based on sieved materials. The equipment comprises a raw material bin; a feeding belt capable of being driven is movably connected below the raw material bin; and a drying device for drying is arranged in front of the feeding belt, and a sorting device for sorting isarranged in front of the drying device. In the equipment, by arranging a drying cylinder, in use, raw materials are conveyed into the drying cylinder on a supporting plate through the feeding belt from the raw material bin, one end of the drying cylinder inclines downwards, and meanwhile rotation at a constant speed is achieved under driving by a driving device; meanwhile a material raising deviceof a special structure is installed in the drying cylinder, and the structure of the material raising device is that a plurality of groups of similar-bucket-shaped material raising blades with different shapes are welded to the inner wall of the drying cylinder. The material raising device raises materials and makes the materials collide with one another in the rotating process, so that the materials do regular free falling motion in the drying cylinder from the upper end to the lower end, and the effects of drying and primary dust separation are achieved.

Description

technical field [0001] The invention relates to the technical field of dry sand making, in particular to equipment for the dry sand making process based on screening material. Background technique [0002] Traditional wet sand making requirements (mud content not more than 3%) and wet sand making process requirements will consume a lot of water in the manufacturing process, and the sewage cannot be collected and discharged indiscriminately, and the sludge discharge will cause environmental pollution. [0003] The existing solution is through secondary recycling and sludge landfill after sewage sedimentation. However, sewage sedimentation requires a large area; sludge landfill is a fundamental solution to the problem of sludge discharge. For this reason, we have proposed equipment for dry sand making process based on sieving material. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present inventi...
