Concrete premixing device and concrete premixing production process

Abstract

The invention relates to a concrete premixing device and a concrete premixing production process, and relates to the technical field of concrete. The concrete premixing device comprises a stirring tank; the bottom of the stirring tank is provided with a main discharge port, the top of the stirring tank is sequentially provided with a sand and stone feeding mechanism, a cleaning mechanism, a mixingmechanism, an auxiliary material mechanism and a clear water circulation mechanism from top to bottom; sand and stones are conveyed to the cleaning mechanism through the sand and stone feeding mechanism, the stones are conveyed to a mixing and stirring machine through the cleaning mechanism, the sand and the stones are stirred in the mixing and stirring machine, and after concrete in the stirringtank is completely discharged, a mixed material in the mixing and stirring machine is introduced into the stirring tank, and concrete materials in the auxiliary material mechanism and the clear watercirculation mechanism are introduced into the stirring tank. The device has the technical effect of improving the concrete forming efficiency and the concrete forming quality.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a ready-mixed concrete device and a production process thereof. Background technique [0002] Ready-mixed concrete is also called commercial concrete. Commercial concrete refers to concrete that can be sold or purchased for commercial purposes. Most of the current building construction uses commercial concrete. [0003] A general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to cement as cementing material, sand and stone as aggregate; mixed with water (with or without admixtures and admixtures) in a certain proportion, and obtained by stirring, molding and curing. Cement concrete, also known as ordinary concrete, is widely used in civil engineering. [0004] The existing Chinese patent with the publication number CN109049333A discloses a ready-mixed concrete raw ma...

AI Technical Summary

Problems solved by technology

[0005] The defect of the above-mentioned technical solution is that the various conveying methods of sand and stones are uniformly conveyed into the cylinder body, and then the stirring shaft is used to drive the stirring blades to stir the concrete material, so the next concrete product in the cylinder body needs to be Wait for all the sand and stones to pass into the cylinder, and at the same time need to wait for the cylinder to be fully stirred before the finished concrete can be produced. At the same time, the concrete is easily stained with dust during the transmission process, which affects the molding efficiency and quality of the concrete.
