Roller piece crossing combined conveying type supporting pipe exhaust dryer

Abstract

The invention discloses a roller piece crossing combined conveying type supporting pipe exhaust dryer. The major characteristic of the dryer is a roller piece crossing combined type conveying mechanism which is formed by transversely laying multiple supporting pipes in a longitudinal and horizontal direction; the two ends of the supporting pipes are provided with bearings respectively; the bearings are fixed on bearing supports at the two ends respectively; one end of each supporting pipe is provided with a double-groove transmission wheel; each supporting pipe is provided with roller pieces;the roller pieces on one supporting pipe and the roller pieces on the adjacent supporting pipe are orderly arranged and installed in a crossing manner; and a high-pressure fan is connected to one endof a heat exchanger box of the dryer and is used for sending hot air with a set temperature into the supporting pipes and then exhausting the hot air from exhaust holes of the supporting pipes. By adopting the roller piece crossing combined conveying type supporting pipe exhaust dryer, when the dryer runs, under transmission of a motor and a transmission belt, all the supporting pipe components roll in one direction, exhausting of the hot air from the exhaust holes is multi-directional, and a material can be multi-directionally heated at a close range when passing through a space above supporting pipes, so that water evaporation of the material is fast, the efficiency is improved, and the quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of drying, and in particular relates to a support pipe exhaust dryer with cross-combined conveying of roller sheets. Background technique [0002] Belt dryers are currently divided into single-layer and multi-layer, but the working principle is basically the same. It is composed of stainless steel mesh belt, mesh belt transmission mechanism, circulating fan, distributor, heat exchanger, box and other main components. The working principle is that the material is evenly spread on the mesh belt by the distributor, and moves forward with the conveying mesh belt. The hot air is blown vertically to the material layer by the fan to heat the material and evaporate the water to achieve the drying effect. [0003] The problem is: [0004] When the mesh belt dryer is blocked by the material, the hot air penetration is poor, and the drying material is heated unevenly, especially the sheet material. Since the material...

AI Technical Summary

Problems solved by technology

[0004] When the mesh belt dryer is blocked by the material, the hot air penetration is poor, and the drying material is heated unevenly, especially the sheet material. Since the material distributor has a certain thickness when spreading the material, the material sandwiched in the middle cannot be heated by the hot air. Blowing will affect the heat and make it difficult for the water to evaporate, which will affect the drying quality. Both the traditional multi-layer belt dryer and the single-layer belt dryer are large in size and waste space resources.
