Rotary drying device suitable for high moisture material

Abstract

The invention provides a rotary type dryer which is suitable for high moisture materials. The dryer comprises a cylinder body, a driving device and a riding wheel device; a preheating zone, a baking zone and a drying zone are successively divided in an inner cavity of the cylinder body from head to tail; a plurality of lifting blades I rearward inclined with the bus of the cylinder body, a lifting blade II perpendicular to the bus of the cylinder body, a lifting blade III frontward inclined with the bus of the cylinder body and a lifting blade IV rearward inclined with the bus of the cylinder body are respectively arranged on the inner walls of the cylinder bodies of the preheating zone, the front zone and rear zone of the baking zone and the drying zone, and a plurality of the gammadia lifting blades with crisscross brackets are arranged in the cylinder body of the drying zone; a plurality of arch breaking chains, the two ends of which are fixed with the inner wall of the cylinder body, are arranged on the inner wall of the cylinder body. The rotary type dryer has the advantages that the dry processing can be directly performed to the high moisture materials, the equipment investment and the occupied area are effectively reduced, the processing period is shortened, the secondary pollution is avoided, the energy consumption and the operating cost are decreased, the moisture content can be decreased to 3 to 5 percent after the dry processing, and the dry processing effect is good.

Description

technical field [0001] The invention relates to a drying equipment for water-containing materials, in particular to a rotary dryer suitable for drying high-moisture raw materials and solid wastes in industries such as building materials, chemical industry, and papermaking. Background technique [0002] At present, in building materials, chemical industry, papermaking and other industries, the drying equipment used for raw materials and waste mainly includes single-cylinder rotary dryers, double-cylinder rotary dryers, three-cylinder rotary dryers and vertical dryers. dryer. Existing drying equipment has relatively strict requirements on the initial moisture of materials, such as single-cylinder rotary dryers, when the initial moisture of the materials to be dried is greater than 25%, it is difficult for the equipment to dry them, or even unable to dry them. Operation; vertical dryer, double-cylinder rotary dryer, and three-cylinder rotary dryer have stricter requirements on...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a rotary dryer suitable for high-moisture materials (25%-85%) in view of the deficiency that existing drying equipment cannot directly dry high-moisture materials (≥25%). type dryer to reduce equipment investment and floor space, shorten the processing cycle, avoid secondary pollution, reduce energy consumption and operating costs
