Abstract
The invention discloses a production method of casting briquette, which utilizes anthracite as a main material and coking coal, bonder and additive as auxiliaries to produce the casting briquette. The production method includes the following steps: feeding the anthracite, the coking coal, the bonder and the additive into a feed bin for metering after being crushed by a crusher; proportioning the anthracite, the coking coal, the bonder and the additive according to the preset production formula before feeding the same into a primary mixing system to mix uniformly, and feeding the same into a mixing feed bin; feeding mixed materials from the mixing feed bin into a secondary mixing system, forming in a punching manner and producing green briquette; drying the green briquette in a drying furnace at a high temperature and cooling the same to form the casting briquette. The invention further discloses the casting briquette produced by the above preparation method, which can be used as new fuel to substitute for casting coke.
Description
Technical field
The present invention relates to the casting molded coal technical field, relate in particular to a kind of casting molded coal and working method thereof.
Background technology
Exploitation coke substitute technology is to solve the high-quality caking coal shortage, satisfies the needs of industry STRENGTH ON COKE such as metallurgy, machinery, chemical industry and alleviates the effective way of environmental pollution.For this reason, countries in the world are dropped into a large amount of such technology of human and material resources exploitation one after another, have obtained good progress.China lacks low ash, low-sulfur, coking coal resource that cohesiveness is good, along with Iron And Steel Industry and Development in Machine Industry, is becoming tight coking coal resource day and price rises steadily, and forces people to go to study coke substitute production technology.Casting is the ideal substitute of foundry coke with moulded coal.
Clean coal technology is the important technology of control pollution, save energy and raising coal resources utilization ratio.It is exactly to greatly develop shaped coal technology that China develops one of main path of clean coal.Coal powder formation is produced moulded coal or formed coke,, not only can practice thrift coal resources, also have the remarkable environmental benefit for industry provides clean raw material or fuel.Shaped coal technology belongs in " catalogue is instructed in industry restructuring " (2005 editions) that State Council openly issues encourages intermediate item.State Council is about promoting some suggestions (No. (2005) 18, promulgated by the State Council) that coal-mining industry develops in a healthy way and State Planning Commission about all spelling out encourage growth shaped coal technology energetically in the files such as notice of printing and distributing " Chinese clean coal technology the ninth five-year plan and development outline in 2010 ".Develop coke substitute shaped coal technology, not only can satisfy the needs of industry STRENGTH ON COKE such as metallurgy, machinery, chemical industry, also can enlarge coking coal resource, solve the overstocked problem of fine coal and significantly alleviate environmental pollution.
Utilizing hard coal production casting to use shaped coal technology, is coal deep processing frontier.Succeeding in developing of this technology not only can prolong enterprise's industrial chain, improves the business economic benefit, and meets clean coal developing direction and national coal industry policy, has vast market prospect.
Summary of the invention
To above-mentioned defective, the object of the invention is to have proposed a kind of casting molded coal and working method thereof, the alternative foundry coke of casting molded coal product that this working method is produced.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of working method of casting molded coal is a main raw material with the hard coal, is aided with coking coal, sticker and Additive Production casting molded coal, may further comprise the steps:
Hard coal, coking coal, sticker and additive respectively after crusher in crushing, are got in the feed bin and measure;
After carrying out proportioning according to preset production formula, get into stir in the one-level stirring system after, get in the mix feed bin;
After the mixed material that comes out from the mix feed bin got into the secondary stirring system, green briquette was produced in impact briquetting;
Above-mentioned green briquette gets into and carries out the high temperature drying processing in the drying oven, processes the casting molded coal finished product after the cooling.
Preferably, green briquette gets into and carries out the high temperature drying processing in the drying oven, and its drying temperature is 500-600 ℃.
Preferably, the defective green briquette after the impact briquetting, incoming stock broken process.
Preferably, the defective casting molded coal finished product of processing after the cooling is as the raw materials for production of casting molded coal.
A kind of casting molded coal is a main raw material with the hard coal, is aided with coking coal, sticker and Additive Production casting molded coal, uses the working method of above-mentioned each described casting molded coal and processes.
Compared with prior art, the present invention has following beneficial effect:
In a kind of casting molded coal working method that the present invention proposes, be main raw material, be aided with coking coal, sticker and Additive Production casting molded coal with the hard coal; Raw material is independent respectively broken; After fragmentation reaches the requirement of grain size distribution, carry out proportioning, stirring according to a certain percentage, the mixed material after the stirring is by the impact molding machine moulding; Green briquette carries out high temperature drying to be handled, and cooled moulded coal is the casting molded coal product.Use the casting molded coal that aforementioned production method is processed, this casting molded coal can be used as a kind of fresh fuel and substitutes foundry coke.
Description of drawings
According to embodiment and accompanying drawing the present invention is done further explain below.
Fig. 1 is the outflow synoptic diagram of the working method of a kind of casting molded coal of the present invention's proposition.
Embodiment
Fig. 1 is the outflow synoptic diagram of the working method of a kind of casting molded coal of the present invention's proposition.
With reference to Fig. 1, in the working method of a kind of casting molded coal that the present invention proposes, main production raw material is a hard coal, and subsidiary material are coking coal, additive and sticker, and this method comprises the steps:
Hard coal, coking coal, sticker and additive after the independent fragmentation, after fragmentation reaches the requirement of grain size distribution, are got in the feed bin and measure in crusher respectively;
After carrying out proportioning according to preset production formula, raw material gets in the mix feed bin after getting into and stirring in the one-level stirring system;
The mixed material that comes out from the mix feed bin carries out impact briquetting after getting into the secondary stirring system in the impact molding machine moulding, produce green briquette;
Above-mentioned green briquette gets into and carries out the high temperature drying processing in the drying oven, and its drying treatment temperature is 500-600 ℃, processes the casting molded coal finished product after the cooling.
In above-mentioned casting molded coal working method; Additive as the casting molded coal raw material is the processing waste of coke-oven plant, adds certain proportion of additive in the casting molded coal production process, both can play the moulded coal skeleton function; Improve the intensity index of casting molded coal, can reduce production costs again.
