Raw material sand treatment device for producing concrete

Abstract

The invention relates to a raw material sand treatment device for producing concrete, which comprises a bottom plate, side plates are arranged on the two sides of the bottom plate, an outer cylinder is fixedly arranged between the side plates on the two sides, an inner cylinder located in the outer cylinder is rotationally arranged between the side plates on the two sides, a first driving motor used for driving the inner cylinder to rotate in the outer cylinder is fixedly arranged on the side plate on one side, a plurality of first stirring shafts penetrate through the cylinder wall of the inner cylinder in the circumferential direction of the inner cylinder and are rotationally connected with the cylinder wall of the inner cylinder, a plurality of groups of first stirring shafts are arranged in the length direction of the inner cylinder, each first stirring shaft is provided with a plurality of first stirring rods, each first stirring rod is internally provided with a first heating piece used for heating the corresponding first stirring rod, and a first driving device for driving the first stirring shafts to rotate on the cylinder wall of the inner cylinder when the inner cylinder rotates in the outer cylinder is arranged between the outer cylinder and the inner cylinder. The device has the advantage of improving the raw material sand heating efficiency.

Description

technical field [0001] The application relates to the field of concrete production, in particular to a raw material sand processing device for concrete production. Background technique [0002] Concrete is 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 the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] The Chinese patent application publication number CN112683029A discloses a raw material sand drying device for concrete production. The staff injects the raw material sand into the inner cylinder through the material pipe, and then starts the heating plate and the heating block to realize the heating inside the inner cylinder. Then it brings ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following technical defects: the inner wall and the outer wall of the inner cylinder can be directly heated by using the heating plate and the heating block, thereby realizing the indirect heating of the inner space of the inner cylinder. The raw sand directly contacting the inner wall of the inner cylinder has a better heating and drying effect, while the raw sand inside the pile of raw sand that is not in direct contact with the inner wall of the inner cylinder does not have a better heating effect
