Description
Technical field
The invention belongs to coal high-efficiency and utilize technical field, especially relate to a kind of fragmentation and dry device for improving quality that integrates brown coal.
Background technology
Brown coal have another name called the bavin coal, are the minimum pit coals of degree of coalification, a kind of brownish black, lacklustre grizzle between peat and pitch coal.China's brown coal proven reserve are 1,303 hundred million tons, account for 1/3 of coal in China reserves, and reserves are huge.And the general depth of burial of brown coal is shallow, and minable coal seam is thick, and cost of winning is low, mostly suitable strip mining transformation.But, because brown coal calorific value low (generally between 2700-3600Kcal/kg), moisture high (total water is between 26-40%), run-of-mine coal (ROM coal) is soft, and porosity is large, and is easily cracked, easy-weathering, oxidation, burning-point is low, the outward transport difficulty.Inner Mongol brown coal reserves account for 77% of the whole nation, because the Inner Mongol serious water shortage can not develop electric power stations near coal-mines in a large number, the essential outward transport of the brown coal that produce, and because long distance transportation is uneconomical, need to carries out dehydrating after the fragmentation to brown coal in order just addressing this problem, and then to transport again.
At present state, inside and outside, the fragmentation of brown coal and drying plant are separately independently equipment, brown coal broken general adopts hammer broken etc.; The drying plant kind of brown coal is more, and roller drying, vibrating mixed flow drying, fluidised bed drying etc. are arranged.Technical process is satisfied dry Belt Conveying to the moisture eliminator that passes through that requires and is carried out drying generally with the screening of the process of the high-moisture brown coal after the fragmentation, can not satisfy the macrobead that drying requires, and then enters crusher by revert system and carries out again broken.In technique, for the thin broken of brown coal, need to set up specially corresponding disintegrating apparatus, the brown coal after the fragmentation need to adopt belt or bucket to carry and be transported to moisture eliminator again.These equipment take up an area large, and investment is high, and flow process is complicated.Present stage, state, inside and outside also not with the broken of brown coal and the dry brown coal device for improving quality that integrates.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of fragmentation and dry device for improving quality that integrates brown coal, this equipment has been realized pulverizing and dry process combination, greatly reduced brown coal upgrading floor space, reduced equipment cost, drying efficiency is high, has greatly improved production efficiency.
For achieving the above object, the present invention adopts following technical scheme:
A kind of fragmentation and dry device for improving quality that integrates brown coal, comprise base, body of heater, cloth tray, breaker roll, heat exchanger plates and drive unit, body of heater is installed in the top of base, be provided with the high speed hot gas entrance that communicates with the body of heater inner chamber on the base, upper of furnace body is provided with material inlet and material outlet, be provided with heat exchanger plates in the body of heater, feed-pipe and accumulation storehouse, heat exchanger plates is the platy structure of hollow, described heat exchanger plates connects respectively the air inlet nest of tubes that is arranged on the body of heater shell wall and the nest of tubes of giving vent to anger, feed-pipe one end is corresponding with material inlet, the other end communicates with the accumulation storehouse, pile up the bottom, storehouse and contact with cloth tray, the cloth tray top is provided with breaker roll, and is gapped between breaker roll and the cloth tray, cloth tray is installed on the drive unit, and drive unit is positioned at base.
Described fragmentation and the dry device for improving quality that integrates brown coal is provided with heat exchanger plates and supports on its heat exchanger plates.
Described fragmentation and the dry device for improving quality that integrates brown coal, its heat exchanger plates is obliquely installed.
Described fragmentation and the dry device for improving quality that integrates brown coal, the angle of inclination of its heat exchanger plates is supported by heat exchange and is adjusted its angle of inclination.
Described fragmentation and the dry device for improving quality that integrates brown coal, it is piled up to be provided with between storehouse and the body of heater shell wall and piles up the storehouse support.
Described fragmentation and the dry device for improving quality that integrates brown coal is provided with feed-pipe and supports on the outer wall of its feed-pipe
Described fragmentation and the dry device for improving quality that integrates brown coal, its breaker roll is at least 2, and is arranged symmetrically with in cloth tray.
Described fragmentation and the dry device for improving quality that integrates brown coal, it is piled up the storehouse and is the hourglass shape structure.
Because adopt aforesaid technical scheme, the present invention has following superiority:
1, the plant area area is little.The fragmentation of original brown coal and drying plant are independent of each other, therefore just need to occupy respectively very large place, and the mass transport after the fragmentation is needed other working equipment and takies corresponding place to the process of moisture eliminator.The efficient device for improving quality of these integrated form brown coal only need to occupy original drying nest place, 1/5 of traditional technology layout that the place occupation rate is not enough.
2, equipment cost is low.The efficient device for improving quality of integrated form brown coal has been saved the handling equipment of broken rear mass transport to the drying plant process, compare traditional fragmentation and drying process equipment, its cost more than 1/2.
3, efficient simple in structure is high.The efficient device for improving quality of integrated form brown coal can by the control of exchange hot plate (pipe) quantity, be controlled its heat interchanging area; By the gap between cloth tray and the breaker roll is adjusted, satisfy the grain graininess requirement of its broken rear material.
4, the scope of application of charging brown coal granularity is larger.Owing to adopt roller crushing, the granularity of its charging brown coal can be selected different sizes according to the diameter of breaker roll, and the maximum feed granularity can reach 200mm.
5, the granularity of discharging brown coal can be adjusted.Discharging brown coal granularity can be adjusted gap between breaker roll and the cloth tray and the crushing force of breaker roll by adjusting hydraulic ram or spring, and then change broken after the granularity of material, in addition, by the wind speed of adjusting high speed hot gas, the angle of heat exchanger plates, further control the size range of dry rear material, dry rear raw meal particle size can be 0
~Adjust as required between the 10mm.
