Dry-mixed mortar gravel raw material treatment device

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a dry-mixed mortar gravel raw material treatment device. Gravel raw materials are dried. The dry-mixed mortar gravel raw material treatment device comprises a cylindrical sealing barrel, and supporting legs are vertically and fixedly mounted below a bottom plate of the sealing barrel. A rotary motor isvertically and fixedly mounted on a top plate of the sealing barrel through a motor seat, and an output shaft of the rotary motor penetrates through the top plate of the sealing barrel and stretches into the sealing barrel. An annular feeding opening is formed on the top plate of the sealing barrel around the motor, and an annular first striker plate is mounted at the position, located on the edgeof the feeding opening, of the upper portion of the top plate. A dispersing mechanism, a grinding mechanism and a drying mechanism are sequentially arranged in the sealing barrel from top to bottom.When the dry-mixed mortar gravel raw material treatment device is adopted for drying the gravel raw materials, the gravel raw materials can be dried sufficiently and evenly, the situation that screening holes are blocked by the gravel raw materials in the subsequent screening process is avoided, the surfaces of the gravel raw materials are ground into filleted corner shapes, and the precision in the subsequent screening process is improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a device for processing dry-mixed mortar and gravel raw materials. Background technique [0002] Dry-mixed mortar refers to a granular or powdery building material that is physically mixed in a certain proportion with dried and screened aggregates, inorganic gelling materials and additives, and can be used directly after mixing with water. Dry-mixed mortar plays the role of bonding, lining, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. The sand and gravel raw materials in the dry-mixed mortar are mainly quartz sand, river sand, broken limestone, etc. Before use, the sand and gravel raw materials containing impurities must be washed and dried, and then the sand and gravel raw materials must be screened. At present, the following problems exist in the drying of sand and g...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a dry-mixed mortar sandstone raw material processing device, the purpose is to solve the following problems existing in the current drying of sandstone raw materials: (1) the moisture on the surface of sandstone raw materials will make the sandstone raw materials agglomerate together, It makes it difficult for the sand and gravel raw materials to be fully and uniformly dried, which in turn causes the sand and gravel raw materials to block the screening holes in the subsequent screening process, which damages the equipment and reduces the screening effect; (2) the surface of the sand and gravel after drying There are many irregular sharp corners, which reduces the screening accuracy in the subsequent screening process
