Novel vertical drying equipment

Abstract

The invention discloses novel vertical drying equipment, which comprises a drying tower body with drying chambers. The drying tower body is provided with a feeding hole on the upper portion and a discharging hole on the lower portion, ventilative screen plates are mounted inside the drying tower body and between the feeding hole and the discharging hole, and an included angle between each ventilative screen plate and the cross section of the drying tower body is larger than zero and smaller than 90 degrees. The novel vertical drying equipment is simple in structure, small in occupation area, energy-saving, high in drying efficiency, low in cost and convenient in operation, and can be used for first drying or first discharging according to different material particle sizes, and accordingly, the problems of adhesion, blockage, revert and the like in drying of highly fine materials high in water content are solved, production process is simplified especially, potential equipment accidents are eradicated, investment is reduced, and benefits are improved.

Description

technical field [0001] The invention relates to drying equipment for materials, in particular to a drying and drying device for mixed materials in industries such as coal mines, chemical industry, mines, and grains, which have large proportions, uneven particles, require low-temperature drying, and must be continuously produced in large quantities. Background technique [0002] In the raw coal drying equipment of the prior art, the traditional rotary flue gas (steam) drying technology has been continued. There are two types of vertical and horizontal. The structure is mainly composed of a rotary body, a lifting plate, a transmission device, a support device and a sealing device. circle and other components. The rotating speed is basically fixed, and the appearance of the rotating body is a cylinder with a certain inclination angle. The material needs to be fed from the higher end, and the high-temperature hot flue gas (steam) and the material flow into the cylinder together....

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a new type of vertical drying equipment with simple structure, small footprint, energy saving, high drying efficiency, low cost and convenient operation. The size is different so that the material is dried first and the material is discharged first, which completely solves the problem of sticking, clogging and returning material in the drying process of materials with high water content and fine particle size.
