A processing device for raw material sand for concrete production

Abstract

This application relates to a raw material sand processing device for concrete production, which includes a bottom plate, side plates are arranged on both sides of the bottom plate, an outer cylinder is fixedly arranged between the side plates on both sides, and an outer cylinder is installed between the side plates on both sides. In the inner cylinder, a first drive motor for driving the inner cylinder to rotate in the outer cylinder is fixedly arranged on one side plate, and a plurality of first drive motors are installed on the wall of the inner cylinder along the circumferential position of the inner cylinder and connected in rotation. A stirring shaft, a plurality of first stirring shafts are arranged in multiple groups along the length direction of the inner cylinder, each first stirring shaft is provided with a plurality of first stirring rods, and each first stirring rod is provided with a The first heating member heated by the first stirring rod is provided between the outer cylinder and the inner cylinder to drive a plurality of first stirring shafts to rotate on the inner cylinder wall when the inner cylinder rotates inside the outer cylinder. Device; this application has the advantage of improving the heating efficiency of raw sand.

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
