Description
Technical field
The utility model relates to chemical industry unsetting solid material fluidization field, particularly a kind of anti-blocking fluidized bed type blow sorting apparatus for coking industry.
Background technology
Coking coal is that one contains certain moisture (≤14%) and the unsetting material of grade composition more complicated (generally dividing by >25mm, 25mm ~ 10mm, 10mm ~ 5mm, 5mm ~ 3mm, 3mm ~ 1.5mm, 1.5mm ~ 1mm, <1mm), also contains rigid block foreign material (as stone, wooden unit, ironware etc.) and the easy winding-type foreign material of flexibility (as straw, woven bag, cloth, the rope made of hemp etc.) 2 large class foreign material in addition in coking coal.Coking coal enters the fineness level that ratio that stokehold need be crushed to grade≤3mm accounts for 65% ~ 80%.
Limit by resource and cost, modern coking generally adopts coal-blending coking technology, and because each single grade coal exists materialization difference, therefore to the pulverizing of as-fired coal material, coking industry has " joining after first powder ", " first joining rear powder " 2 kinds of techniques.Some coal chemical enterprises adopt selective molecular attraction for preventing coal charge from excessively pulverizing, and selective molecular attraction had both comprised to be selected to pulverize to single grade coal, also comprises after all kinds of coal charge coordinates and carries out sieve classification, then the coarse granule pulverized will be needed to be crushed to the fineness level of technological requirement.Its advantage had both maintained the coking physical and chemical performance of coal charge, can effectively reduce pulverizer energy consumption again.Equipment coal charge being carried out to sieve classification mainly contains machinery and selection by winnowing 2 kinds of modes; Wherein fluidized bed type coal blow sorting apparatus applies a more class pneumatic separator in recent years.
In the fluidized bed type blow sorting apparatus course of work, differ because the uneven and moisture of coal charge granularity distributes in size fractionated material and there is density variation, add the impurity containing aforementioned heterogeneity in material, when the material that particle in material flow in machine is big and heavy or density is larger (the comprising impurity) rate of settling is higher, critical fludization velocity needed for it is also large, when fluid bed wind speed < critical fludization velocity, such material will deposit to fluidisation bed surface and form putty, thus worsen fluidisation operating mode, need periodic cleaning, labour intensity is large, and impact is produced.
Utility model content
The purpose of this utility model is just to provide a kind of anti-blocking fluidized bed type blow sorting apparatus solving blockage problem.
Solution of the present utility model is such:
A kind of anti-blocking fluidized bed type blow sorting apparatus, comprise the air compartment of fluidising chamber and multi-stage serial connection and be positioned at the air distribution plate of air compartment, it is characterized in that: at least two air compartments are provided with unimpeded pipe, described unimpeded pipe one end is connected with air distribution plate, and the air distribution plate place be connected with unimpeded pipe has unimpeded mouth; Blast cap on described air distribution plate comprises blast cap around common blast cap and unimpeded mouth, and wherein common blast cap controls wind direction and is fluidising chamber's feed end toward discharge end, and around unimpeded mouth, blast cap controls wind direction towards discharge gate; Be provided with separately every formula dispenser at described unimpeded pipe.
Technical scheme also comprises more specifically: each unimpeded open area of described air distribution plate is 0.06m
2~ 0.12m
2.
Further: described unimpeded pipe is down through corresponding air compartment.
Further: the exit lower end of described unimpeded pipe is provided with putty conveyer.
The utility model has the advantages that:
1, fluidized bed air separating screening machine can realize automatically tackling blockage, avoids the large and problem such as work under bad environment, long impact production consuming time of block clearing labour intensity in artificial frequent ingress engine.
2, because unimpeded can on-line automaticly in fluid bed running to be carried out, without the need to shutting down, to keeping, the continous-stable of production line is significant.
3, blockage-removing mechanism arrange and the quantity that comes into operation can select according to operating mode, each unimpeded mouth unimpeded frequency and effluent amount controllability good, simple to operate.
4, can application good, all applicable to the wind-force fluid bed (as directly utilized the fluidized bed type coal humidity drier of coke oven flue waste gas, the fluidized bed type coal damping machine etc. of indirect) of character similar materials.
