The invention discloses a kind of device for sorting different grain size cleaned coal, belong to cleaned coal sorting technology field, including streaming tank, coal cylinder is provided with the top of streaming tank, bottom is provided with air inlet pipe；Steam pipe is provided with a side wall of streaming tank, another side wall takes coal plate provided with some stretch into inside streaming tank, and pressure gauge and some thermometers are additionally provided with the fluidisation pot sidewall for taking coal plate is set.The device is using thermophoretic effect sorting different grain size cleaned coal, mixed using steam and air in streaming tank, under the cross-mixing of steam and air concentration gradient is being formed along streaming tank short transverse, because contained air capacity is different in the steam on streaming tank different height direction, the temperature of mixed gas is also different.Varigrained coal grain is fed in coal bucket, and in the Temperature Distribution being gradually reduced along streaming tank short transverse, suspended state is presented in coal grain, and thermophoresis phenomenon is realized under concentration gradient effect, and the apparatus structure is reasonable in design, easily realizes, and energy-conserving and environment-protective.
Description
Technical field
The invention belongs to cleaned coal sorting technology field, is related to a kind of device for sorting different grain size cleaned coal.
Background technology
China is coal consumption big country, in order to realize that the sustainability of energy-conserving and environment-protective and coal uses, improves coal product
The economic benefit of quality and coal consumers.The core of Coal dressing is coal separation during steam coal.Existing coal jigging
With the device such as inclined trough washing coal can be sorted for bulk, middle piece, fritter, beans etc., to meet different user to coal cinder granularity
It is required that the sorting of further varigrained coal grain has to use sieve, screening not only causes artificial consumption, and
It is irregular that uneven coal grain will also result in the heat absorption such as burning, pyrolysis, it is necessary to using significantly more efficient method to different grain size coal
Grain is more accurately sorted.
The content of the invention
It is an object of the invention to provide a kind of device for sorting different grain size cleaned coal, the apparatus structure is reasonable in design, easily
Realize, coal particle size distinguishes the problem of coarse during can effectively solve the problem that coal washing in the prior art.
The present invention is to be achieved through the following technical solutions：
A kind of device for sorting different grain size cleaned coal, including streaming tank, are provided with coal cylinder, bottom is provided with the top of streaming tank
Air inlet pipe；Steam pipe is provided with a side wall of streaming tank, another side wall takes coal plate provided with some stretch into inside streaming tank, set
Put and pressure gauge and some thermometers are additionally provided with the fluidisation pot sidewall for take coal plate.
Preferably, it is described take coal plate be two, first respectively from top to bottom set takes coal plate and second to take coal plate.
Preferably, thermometer is also two, is respectively arranged on first and takes the first thermometer above coal plate, and sets
The second temperature meter above coal plate is taken second.
Air inlet pipe end is connected with blower fan, and intake valve and flowmeter are additionally provided with air inlet pipe.
Steam valve is additionally provided with steam pipe.
Compared with prior art, the present invention has technique effect beneficial below：
The device of sorting different grain size cleaned coal disclosed by the invention, is divided varigrained cleaned coal using thermophoretic effect
Choosing, is provided with steam pipe in a side wall of streaming tank, and air intake duct pipe is provided with fluidisation pot bottom, can be respectively to streaming tank
Middle importing steam and air, are acted in the cross-mixing of steam and air, and concentration gradient is formed along streaming tank short transverse, due to
Contained air capacity is different in steam on streaming tank different height direction, and the temperature of mixed gas is also different.Varigrained coal
Grain is fed in coal cylinder, and in the Temperature Distribution being gradually reduced along streaming tank short transverse, suspended state is presented in coal grain,
Thermophoresis phenomenon is realized under concentration gradient effect, granule coal dust is shown as and is distributed in lower floor, big beans powder is distributed in upper strata, passed through
Be arranged on fluidisation pot sidewall on it is some take coal plate, can by varigrained cleaned coal rationally separate.Apparatus structure design is closed
Reason, easily realize, and energy-conserving and environment-protective, coal particle size distinguishes coarse ask during can effectively solve the problem that coal washing in the prior art
Topic.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1 is steam pipe；2 be steam valve；3 be streaming tank；4 be coal cylinder；5 take coal plate for first；6 take for second
Coal plate；7 be intake valve；8 be air inlet pipe；9 be blower fan；10 be pressure gauge；11 be the first thermometer；12 be second temperature meter；13
For flowmeter.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, the device of sorting different grain size cleaned coal disclosed by the invention, including streaming tank 3, at the top of streaming tank 3
Provided with coal cylinder 4, bottom is provided with air inlet pipe 8；Steam pipe 1 is provided with a side wall of streaming tank 3, another side wall is provided with some stretch into
Coal plate is taken inside streaming tank 3, pressure gauge 10 and some thermometers are additionally provided with the side wall of streaming tank 3 for taking coal plate is set.Enter
The end of tracheae 8 is connected with blower fan 9, and intake valve 7 and flowmeter 13 are additionally provided with air inlet pipe 8, and steam is additionally provided with steam pipe 1
Valve 2.
Preferably, it is two to take coal plate, and first respectively from top to bottom set takes coal plate 5 and second to take coal plate 6；Temperature
Meter is also two, is respectively arranged on first and takes the first thermometer 11 of the top of coal plate 5, and is arranged on second and takes on coal plate 6
The second temperature meter 12 of side.
The device of the sorting different grain size cleaned coal of the present invention, when in use：
Steam valve 2 is first opened, steam is sent in streaming tank 3 from steam pipe 1, air is drawn into air inlet pipe 8 by blower fan 9
In and be fed in streaming tank 3, while varigrained cleaned coal is sent into streaming tank 3 from the top of coal cylinder 4.Coal grain is steaming
Suspended state is under the blowing of vapour and air, while is distributed in the thermograde effect lower leaf along streaming tank height, is being flowed
The pressure of streaming tank 3 and temperature can be measured by changing the pressure gauge installed on tank on different height and the first thermometer 11 and second temperature meter 12
The distribution of degree.Coal plate 5 and second is taken to take coal plate 6 to be used for different grains along the first of the different height directional spreding of streaming tank 3 simultaneously
The coal of degree takes out out of streaming tank 3.
The device sorts different grain size cleaned coal using thermophoretic effect, is mixed using steam and air in streaming tank,
Concentration gradient is being formed along streaming tank short transverse under the cross-mixing of steam and air, due on streaming tank different height direction
Steam in contained air capacity it is different, the temperature of mixed gas is also different.Varigrained coal grain is fed in coal bucket,
