Mesh Belt Dryer

Abstract

The invention provides a net belt drying machine, which solves the problem of nonuniform drying of materials in the thickness direction. The drying machine comprises an oven, a material feeding machine and a hot air conveying device, wherein the material feeding machine and the hot air conveying device are respectively communicated with the oven, the oven is provided with a hollow casing, the interior of the casing is provided with a net belt conveying unit for conveying the material, the net belt conveying unit comprises an upper net belt and a lower net belt which are vertically staggered and can continuously and circularly rotate, the material outlet end of the upper net belt is correspondingly arranged above the material inlet end of the lower net belt, a material turnover device is arranged between the material outlet end of the upper net belt and the material inlet end of the lower net belt, the material turnover device mainly consists of a hydraulic oil cylinder and a material hopper, the telescopic direction of the hydraulic oil cylinder is vertical to the movement direction of the lower net belt, a material inlet of the material hopper is fixedly arranged under the material outlet end of the upper net belt, a material outlet of the material hopper is provided with a metal flexible pipe, and a telescopic head of a hydraulic oil cylinder is fixedly connected with the metal flexible pipe. The drying machine has the advantage that when the materials are conveyed at the upper and lower layers, the material is turned over by the swinging material discharging of the material hopper, and caking is avoided.

Description

Technical field [0001] The invention relates to a drying device, in particular to a mesh belt dryer capable of breaking up agglomerates. Background technique [0002] The mesh belt dryer is generally divided into multi-layer mesh belt conveyor units parallel to each other; when working, the material is distributed on the conveyor belt, the wind penetrates evenly, exchanges heat with the feed particles, and is supplemented by a suction device to discharge evaporated water. In order to achieve the purpose of uniform drying. However, the dryer with this structure has the following problems: when the material layer is unevenly distributed, there will be a local short circuit of the air path, resulting in uneven water removal; and the material layer has a certain thickness, because the material layer is not disturbed, when the wind penetrates , will cause moisture differences in the thickness direction of the material layer. At the same time, each layer of mesh belt conveying u...

Problems solved by technology

[0003] In order to overcome the disadvantage that the materials in the existing ovens are easy to agglomerate, the invention provides a mesh belt dryer, which can not only complete the drying task of the normal oven, but also turn or break the agglomerated materials during material transmission, preventing Uneven drying across material thickness
