Abstract
The production process of the formed coal is completed by conveying, crushing, stirring, conveying, forming, cutting and matching the mineral crushed coal with the crushed coal forming system. It adopts double-roll crushing, push-type double-shaft stirring and coal: 4-8: 1 of water; the particle size of the crushed coal before molding is 0-20 mm, and the viscosity is greater than 1. The coal briquette machine has the advantages of compact structure, continuous forming, high production speed, high efficiency, simple and feasible process, moderate formed coal compactness, high ignition speed and complete combustion, can be cut into pieces as required, and is suitable for collective large-scale coal consumption and small-quantity coal consumption of urban and rural residents.
Description
What broken coal formation system and shaped coal production technique related to is a kind of technology with the moulding of the broken foam material of particle processing and fabricating.
Coal is China's industrial and agricultural production and the required main fuel of the living standards of urban and rural residents.Yet coal produces a large amount of broken coals inevitably in its recovery process, and these broken coals are conveyance transportation difficulty not only, and throwing is loose more, stack inconvenience, and fuel is incomplete, and utilization ratio is low.For this reason, people study invention and have made multiple machineries such as honey-comb briquet, broken coal shaper.These machineries have been got very positive effect for solving the broken coal problem, but their yet exist 1 simultaneously, will be with addition of weighting agent or tackiness agent; 2, broken coal moulding production efficiency is low; Many weak points such as 3, employed broken coal kind selectivity is little.
The objective of the invention is to solve a large amount of broken coals that produce in the Coal Production and provide a kind of high-quality and efficient broken coal formation system and shaped coal production technique fast for society.
Broken coal formation system of the present invention and shaped coal production technique, its broken coal formation system comprises the broken coal transfer mechanism of being made up of three transfer rollers, by two broken coal crushers, two broken stirring mechanisms that pusher biaxial rneader is formed, a screw-pushing type shaper, saddle, cutting machine and supporting actuating unit.The production process route of shaped coal is: the mineral products broken coal at first is transported to first crusher and carries out fragmentation, then adding water stirs and trembles, be transported to second crusher again and carry out the fragmentation second time, adding water again stirs, be transported to shaper at last and carry out moulding, shaped coal transports through saddle, gets the shaped coal product after cutting machine is cut.The key problem in technology of this production technique is: broken coal total amount (being the water that broken coal is added when stirring for twice) with addition of water in moulding process is: broken coal: water=4～8: 1; The granularity of broken coal before entering shaper is: 0～20 millimeter, viscosity is greater than 1.
Broken coal formation system of the present invention and producing and manufacturing technique thereof are compared with prior art, it is reasonable to have system arrangement, compact construction, the continuous equalization of broken coal moulding, production rate is fast, the efficient height, characteristics such as producing and manufacturing technique is simple, prepared shaped coal also has simultaneously: 1, surfacing, smooth, hardness is moderate, easy carrying, stacking; 2, be convenient to the user and do not have broken foam generation by the free stripping and slicing of actual needs; 3, the shaped coal degree of compactness is moderate, characteristics such as the firing speed of igniting is fast, burning is complete, fuel availability height.This shaped coal not only is suitable for using in a large amount of occasions of fuel of using such as collective's brick kitchen range, boiler, also is suitable for the coal consumption of living as vast urban and rural residents.
Accompanying drawing 1 is a broken coal formation system orthographic plan.
Below we will be described in further detail the present invention program in conjunction with the embodiments.
With reference to the accompanying drawings 1, transfer roller (2) will flow to crusher (3) fragmentation endlessly from the mineral products broken coal that blanking port (1) falls, and enter pusher biaxial rneader (9) carry out adding the first time water stir coarse fodder, then coarse fodder is transported to crusher (5) by transfer roller (4) again to carry out the second time broken, then enter pusher biaxial rneader (10) carry out adding the second time water stir grog, this grog flows to screw-pushing type shaper (12) by transfer roller (11) and carries out moulding, shaped coal saddle (7) transport cutting machine (8) cut the finished product shaped coal, (13) are screw-pushing type shaper speed reduction unit among the figure, and (6) are the shaped coal outlet.
In native system, the concrete shape of shaped coal is by the shape and the structures shape of shaped coal outlet (6), and it can make circle, square, cellular coal cinder on demand, or other shape coal cinder; Crusher (3), (5) are the pair roller attrition crushing, and stirrer (9), (10) are pusher biaxial rneader, and the holder rod (14) on the saddle (7) can rotate around axle (15).
In addition, when the granularity of mineral products broken coal own little, and broken foam more for a long time, the crushing process of being finished by crusher (6) second time can omit, more when the broken foam of mineral products broken coal itself, when the less and viscosity of the hardness of coal was big, the stirring technique of being finished by pusher biaxial rneader (10) second time also can omit, it is more simple that its system and operational path just become, and production efficiency does not but reduce.
Also to point out, its broken coal grog of shaped coal production technique of the present invention enter the preceding granularity of shaper (12) should be between 0～20 millimeter, the broken coal granularity of best molding effect of its broken coal and the best result of use of shaped coal should be between 0～10 millimeter.The viscosity of broken coal grog should be greater than 1, and optimum viscosity is greater than 1.5.
Broken coal also needs in moulding process with addition of a certain amount of water in addition, adds water inventory and is: broken coal: water=4～8: 1; The best water yield that adds is: broken coal: water=5～6: 1.The adding of these water should be finished in two batches and when carrying out stirring for first, second twice.
