Uniform-speed discharging and mixing material bin used in pneumatic wet spray machine

Abstract

The invention relates to a uniform-speed discharging and mixing material bin used in a pneumatic wet spray machine. The uniform-speed discharging and mixing material bin comprises a material mixing bin, a material discharging bin arranged at the bottom of the material mixing bin and feeding bins arranged at the top of the material mixing bin; a feeding pulling bin is arranged in the material mixing bin, the material mixing bin and the material discharging bin are provided with an air outlet channel and a through hole, and an air source is connected so that the air source is directly, slantly and upwards blown to the feeding bins of the feeding pulling bin; in the rotating process of the feeding pulling bin, each feed bin can be pneumatically cleaned, so that depositing or accumulation of materials in the feed bins is effectively prevented, the materials are saved as much as possible, the use time of the feeding pulling bin is prolonged, and the number of cleaning and repairing is reduced; the feeding bins adopt vibration type material screening and discharging, and the materials in large particle sizes are prevented from entering the material mixing position and blocking or clamping rotation of the feeding pulling bin; a pressure relief valve is arranged so that the pressure balance in the material mixing bin can be ensured, and normal falling of the slurry materials is ensured; and a hole cover is arranged so that slurry in the material mixing bin can be prevented from being splashed outwards in the rotating process.

Description

technical field [0001] The invention relates to the technical field of wet spraying machines, in particular to a uniform feeding mixing bin used in pneumatic wet spraying machines. Background technique [0002] Mine pneumatic wet spraying machine is a kind of equipment with good comprehensive performance that can reduce springback and save materials. It is widely used in mines, culverts, building foundation pit support, river slope protection and other projects. It generally uses pumping to transport concrete materials, and then pneumatically sprays the concrete materials to the workplace. The working principle of the pneumatic wet spraying machine is generally to use high-pressure gas to blow out the slurry in the storage bin at a high speed, so that it adheres to the surface of the building, so as to achieve the purpose of strengthening and protecting the building. Among them, the most critical factor that determines the working efficiency of the pneumatic wet spraying ma...

AI Technical Summary

Problems solved by technology

Among them, the most critical factor that determines the working efficiency of the pneumatic wet spraying machine is the feeding silo. Since the wet spraying machine uses slurry when it is working, the slurry will easily deposit in the feeding silo in the feeding bin after a long time passing. After a long time of use, it is necessary to take out the feeding dial for cleaning, and the materials deposited in the feeding dial also cause a certain degree of waste, thus affecting the production efficiency of the overall equipment
