Material raising device for ramsbottom dryer

Abstract

The invention discloses a material raising device for a ramsbottom dryer. The device comprises material raising plates 2, a large flange ring 4, a small flange ring 5, a supporting tube 6, material guide plates 7, a feeding plate 8, a discharging plate 9 and other members, wherein the material raising plates and the material guide plates are equally distributed inside a dryer cylinder along the circumference; and due to design of the shape, structure and arrangement position, the material raising direction is changed in the process of rotating and propelling the dryer cylinder, the raising height is reduced, collision between materials and between materials and equipment is greatly reduced, heat is uniformly transferred, materials are propelled easily, and the material damage rate is reduced. The material raising device has the advantages that: the damage rate of a finished product is reduced from over 24 percent to below 13.4 percent, the production efficiency is improved, the service life of the equipment is prolonged, and the device has a simple structure and is convenient for maintenance personnel to repair and clean. Meanwhile, the device can be applied to material raising devices for rotary straight cylinder dryers for coke, slag, fly ash, bentonite, desulfurization gypsum and the like of which the damage rate is needed to be reduced.

Description

Technical field [0001] The invention relates to a material lifting device of a dryer. Background technique [0002] At present, the known semi-coke, also known as semi-coke or coke powder, is a light black block, which is generally fired from clean coal blocks; it can also be an industrial accessory for refining coal tar in chemical plants, with a fixed High carbon, high resistance ratio, high chemical activity, low ash content, low aluminum, low sulfur, low phosphorus characteristics, can replace metallurgical coke, smokeless block and charcoal and widely used in calcium carbide, metal silicon, ferroalloy, ferrosilicon In the production of products such as ferrochrome, silicon manganese, silicon carbide, and chemical fertilizers, the particle size requirement is not less than 5mm. Due to the relatively high content of mud and water mixed before the semi-coke is dried, it is easy to break during the drying process. Most of the lifting devices used in the cylinder cavity of...
