Abstract
The utility model relates to a dryer, in particular to a sludge dryer special for a hollow blade. The sludge dryer special for the hollow blade comprises a machine body consisting of a dryer shell and a dryer shell jacket, wherein at least one rotary hollow shaft is arranged in the dryer shell and provided with the screw-type hollow blade. By the sludge dryer special for the hollow blade, sludge is stirred by the screw-type hollow blade until the granular size is uniform, so that the inside of the dry sludge equals the outside, the noise is low, the sterilization degree is high, and materials and environment cannot be polluted.
Description
Technical field
The utility model relates to a kind of drying machine, the special-purpose sludge drier of especially a kind of hollow blade.
Background technology
Along with the quickening of Urbanization in China and the reinforcement of urban infrastructure construction, wastewater treatment rate progressively improves in recent years, and has supervened a large amount of excess sludges.If these mud can not be in time, effectively and stable treated, will make the regional environment of China and the safety of life bring great hidden danger.Municipal sludge can reduce pathogenic agent after the bakingout process mummification, reduce the magnetism of material to insect, insect, becomes nutritious organic residue.Biological sludge safety after the processing does not have peculiar smell.Mummification can reduce cost and the environmental exposure that landfill causes, and trucking costs reduces greatly, and the biological sludge after the mummification can be used for soil improvement agent, potting soil, Urban Parks etc., can practice thrift transportation cost, avoids buying chemical fertilizer.
Commercial runs such as industrial sludge such as papermaking, chemical industry and pharmacy and rivers and lakes dredging etc. also can produce a large amount of mud.The harmless treatment of mud become in the urban science evolution must solution great environmental issue.Moisture percentage in sewage sludge after sewage work's process dehydration is also up to 75%-85%, and is bulky.No matter final sludge treatment mode is to burn or other purposes, and the drying of mud and moulding are very important.Dried mud is a kind of valuable raw material, under safety condition, is easy to store, can burn, or fuel or as fertilizer sources.
The high mud of mud bag axle and wall sticking phenomenon, particularly viscosity appearred in drying machine easily in the sludge-drying process in the past, easy caking, surperficial mummification and the inside is still the difficult difficult problem of pulverizing of sposh.
The utility model content
The technical problem that the utility model will solve is: for solving the problem of above-mentioned existence, provide a kind of revolution tubular shaft that is positioned to be provided with the hollow blade of type in the shape of a spiral, and be equipped with scraping blade on the blade; Can remove attached to the material on the blade of opposite, prevented that mud from wrapping main shaft and rotating the generation with wall sticking phenomenon together, and heat transfer area be big; Rate of drying improves greatly, and is easy to operate, and noise is low; The sterilization degree is high, and drying effect is good, not the special-purpose sludge drier of the hollow blade of contaminated material and environment.
The utility model solves the technical scheme that its technical problem adopted: the special-purpose sludge drier of a kind of hollow blade comprises the body of being made up of drying machine housing and drying machine housing chuck.
Be provided with at least one revolution tubular shaft in the drying machine housing, the revolution tubular shaft is provided with the hollow blade of spiral, stirs through blade and makes the mud granule size evenly; Hollow blade is provided with scraping blade; Scraping blade axially becomes angle with the revolution tubular shaft, can remove attached to the material on the blade of opposite, has prevented that mud from wrapping main shaft and rotating the generation with wall sticking phenomenon together; Can guarantee heat transfer surface not by the knot that becomes silted up, successive spiral blade has propulsive forward effect and weares and teares little mud.
Drying machine housing both sides are provided with at least one steam inlet; Siccative housing lower end is provided with at least one condensation-water drain; Drying machine housing top is provided with in order to reinforced charging opening; The drying machine case top lid is provided with hot carrier gas and imports and exports, and all passes to thermal barrier in drying machine housing chuck, revolution tubular shaft and the hollow blade, and hot face heats material simultaneously.The revolution tubular shaft is two and side by side horizontally prevents the mud alluvial, effectively protects sealing socket and chock.
The beneficial effect of the utility model is; The special-purpose sludge drier of the hollow blade of the utility model through on the revolution tubular shaft in the shape of a spiral the stirring of the hollow blade blade of type make the mud granule size evenly; And be equipped with scraping blade on the blade; Can remove attached to the material on the blade of opposite, prevent that mud from wrapping main shaft and rotating the generation with wall sticking phenomenon together, thereby dried mud thought and acted in one and the same way, noise is low, the sterilization degree high, not contaminated material and environment.
