Abstract

The invention discloses a method for manufacturing a sintered product by wet sludge, which relates to the technical field of building material manufacture. The technical process comprises the following steps that: the wet sludge with the moisture content being 50 percent to 90 percent is conveyed to a sludge storage cabin, and the wet sludge is conveyed into a stirring machine to be uniformly mixed with pulverized coal refuse after being stirred in the sludge storage cabin; and the materials obtained by mixing the wet sludge and the coal refuse are conveyed to a curing warehouse through a conveyer belt, and the sintered product is obtained through aging, blank preparation, drying and roasting. The method has the advantages that a large amount of sludge and silt is treated, the problem of urban sludge treatment difficulty is solved, the heating value of the sludge is also utilized for producing sintered type novel wall body materials conforming to national standards, the effects of land saving, energy saving and environment protection are reached, and in addition, social and economic effects are obvious.

Description

A kind of method of utilizing wet mud making sintered article

Technical field

The present invention relates to material of construction manufacturing technology field, be specifically related to a kind of method of utilizing wet mud making sintered article.

Background technology

At present; Environment protection has become the problem of national governments' growing interest; In China; Along with the propelling of urbanization process, sedimentary mud in the city river, mud are more and more, how to solve the severe problem that the mud that forms in domestic sludge and the river course after the sanitary sewage disposal has become a lot of cities to face.To also having proposed some solutions like domestic sludge, river and lake mud, but the sludge quantity that it consumed all seldom in the prior art, and the city result of use that solves various a large amount of mud is just not ideal enough for much pressing for.Moreover because the water cut of mud is many, general solution all is earlier with mud, mud drying treatment, then in the processing of carrying out next step, has so just increased treatment scheme, has increased processing cost.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of mud that do not need to wet to carry out drying treatment, directly adds behind the coal gangue through preparation, can be made into the method for sintered article.

Technical problem to be solved by this invention adopts following technical scheme to realize,

A kind of method of utilizing wet mud making sintered article, it is characterized in that: its technological process is following,

Be that wet mud between the 50%-90% is transported to the mud storage bin at first with water ratio; In the mud storage bin, after stirring, be transported in the stirrer and the coal gangue uniform mixing after pulverizing; Wet mud of gained and the mixed material of coal gangue are delivered to Cheng Huaku through conveying belt, through ageing, base, oven dry, roasting, obtain sintering finished.

Useful volume is 300M in the storehouse of described mud storage bin ², mud storage bin set inside has the hydraulic pressure balladeur train, and the middle part is provided with pilot beam, and the top is provided with top cover, and described top cover adopts hydraulic pressure opening.

Said water ratio is the mud about 50%-90%, and its component concentration is between 5-40, and the coal gangue component content of pulverizing is between 60-95.

Said through ageing, base, oven dry, roasting, obtain sintering finished in, digestion time is 2-7 days, drying time is 24-30H, roasting time is 24-30H.

The further technical scheme of the present invention is and the wet mud of water ratio between 50%-90% is mixed with sintering finished coal gangue, can be that one or more of shale, clay, building waste or flyash substitute.

The invention has the beneficial effects as follows that the present invention has not only handled a large amount of mud, mud; Solve municipal sludge and handled difficult problem; Utilized the thermal value of mud to produce the sintering class novel wall material of National standard again; Reached save land, energy-saving and environmental protection, and society and remarkable in economical benefits.
