Efficient three-return-stroke roller dryer for wet sand treatment

Abstract

The invention relates to the technical field of drying equipment, in particular to an efficient three-return-stroke roller dryer for wet sand treatment. The efficient three-return-stroke roller dryercomprises a base, a controller, a conveying belt and a drying mechanism, wherein the controller is arranged at the top of the base through a supporting rod, the drying mechanism comprises a drying box, a warning assembly, a driving assembly and three sets of stirring assemblies, the drying box is vertically arranged through an annular frame body, the warning assembly is arranged at the top of thedrying box, the driving assembly is vertically inserted into the drying box through a bearing, the three sets of stirring assemblies are arranged in the drying box at equal intervals and are connectedwith the driving assembly in a sleeving mode, and the warning assembly and the driving assembly are electrically connected with the controller. According to the efficient three-return-stroke roller dryer for wet sand treatment, the wet sand can be dried in step-by-step and layer-by-layer mode, the drying work can be prompted gradually, the drying stroke is effectively prolonged, the drying efficiency is improved, and the drying effect of wet sand is obviously improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a high-efficiency three-pass drum dryer for wet sand treatment. Background technique [0002] Sand can usually be used as a raw material for construction or environmental protection materials, but sand is usually located in rivers and lakes. After it is salvaged, it usually contains a lot of water. As a raw material for construction or environmental protection materials, it usually needs to control its moisture content. If the rate is too high, it will affect the finished texture of construction or environmental protection materials, affect the use, and thus fail to achieve the expected effect. However, most of the existing wet sand dryers are drum dryers. The wet sand has high adhesion and is easy to accumulate inside it. Every part of the wet sand is dried, which affects the drying effect. In addition, due to the high moisture content of the wet sand, it is easy to ad...

[0002] Sand can usually be used as a raw material for construction or environmental protection materials, but sand is usually located in rivers and lakes. After it is salvaged, it usually contains a lot of water. As a raw material for construction or environmental protection materials, it usually needs to control its moisture content. If the rate is too high, it will affect the finished texture of construction or environmental protection materials, affect the use, and thus fail to achieve the expected effect

However, most of the existing wet sand dryers are drum dryers. The wet sand has high adhesion and is easy to accumulate inside it. Every part of the wet sand is dried, which affects the drying effect. In addition, due to the high moisture content of the wet sand, it is easy to adhere to the inner wall of the drum, resulting in waste of resources and increasing production costs, which is not conducive to improving corporate profits. For some three-pass dryers, the drying effect needs to be improved
