Anti-caking sand dryer

Abstract

The invention relates to an anti-caking sand dryer, comprising a drying barrel, a controller, a sand incoming tube, a sand outgoing tube, a hot air tube and a plurality of support legs. A dischargingmechanism is arranged in the sand outgoing tube. A crushing mechanism and a filtering mechanism are arranged in the drying barrel; the crushing mechanism includes a first motor, a spindle, a rocking component and a plurality of crushing components; the filtering mechanism includes a strainer, a sealing component, support rods and a driving component. The anti-caking sand dryer has the advantages that blades are rotated and rocked through the crushing mechanism during drying, sandstone is cut and crushed at different parts, and drying effect being affected by moist sand caking is avoided; in addition, after drying, the strainer in the filtering mechanism is rotated down, a discharge plate in the sand outgoing tube is rotated down, sand in the drying barrel slips from the bottom, accumulation of fine sand, passing through the strainer, in the drying barrel is avoided, sand damage and dryer damage are avoided, and the dryer has improved practicality.

Description

technical field [0001] The invention relates to the field of building material production and processing equipment, in particular to an anti-caking sand dryer. Background technique [0002] Sand dryer, also known as river sand dryer, yellow sand dryer, and quartz sand dryer, is a drying equipment for processing a large amount of materials. It has excellent drying effect for drying sand, river sand, quartz sand, etc. Its advantages are large production capacity, wide application range, small flow resistance, large fluctuation range allowed in operation, and convenient operation. [0003] However, during the operation of the existing sand dryer, the sand is easily bonded together due to its high humidity before drying, so that the inside of the sand is not easily heated during drying, so that the sand is easy to agglomerate, and for some fine sand , because the size of the sand is smaller than the mesh of the filter screen inside the drying box, these fine sand particles are ...

AI Technical Summary

Problems solved by technology

[0003] However, during the operation of the existing sand dryer, the sand is easily bonded together due to its high humidity before drying, so that the inside of the sand is not easily heated during drying, so that the sand is easy to agglomerate, and for some fine sand , because the size of the sand is smaller than the mesh of the filter screen inside the drying box, these fine sand particles are easy to pass through the filter screen and remain at the bottom of the drying box, causing sand loss. These lost sand accumulates inside the dryer. It is easy to affect the operation of the equipment, and in severe cases, the equipment will be damaged, which will reduce the practicability of the existing sand dryer
