Abstract
The utility model relates to a vertical screw quantitative discharging device for a coke furnace coal cart, comprising a hyperbolic coal bunker, a screw mechanism and a drive mechanism. A screw is arranged in the coal bunker, and a variable-speed electric motor is driven by a speed reducer. The quick and quantitative coal charge is realized, the coal loading of a carbonization chamber is added, and pollution is reduced by using the utility model.
Description
The utility model belongs to coke oven coal charging car vertical spin blanking device.
Coke oven production is batch production for the single hole coking chamber, promptly coalings, and---doing slide---discharging of the coke---coalings ... working cycle.Requirement coalings that speed is fast, the time is short, coal capacity is many and stablize, and can save time like this; Save the energy, also favourable to the coke oven prolongs life, and can reduce leaking of flue dust.
The interior quality of coalingging of coking chamber in modern age more and more causes the attention of domestic and international coal tar industry.All manage to improve the quality of coalingging by fair means or foul.Guaranteeing to improve the coal amount as far as possible under the requisite space height of coking chamber top, this can not only improve the throughput of single hole stove, and directly has influence on the quality of coke and tar.At present, the most pit kiln of China still adopt the hyperbolic line coal bunker, and by the gravity of the coal self gravitation blanking method of coalingging, its device is simple, and following coal is fast, but the bad control of coal amount down is difficult to realize quantitatively coalingging.If Japan's employing garden dish feed-type, but that it requires the moisture content of coal is strict is moisture content height then the putty phenomenon is arranged.Germany adopts the flat spin cutting mode, and feed opening is arrived in the coal horizontal shift of coal bunker, falls by the deadweight of coal then.Its motivating force of this dual mode just realizes quantitatively, is still at last and falls reinforced by the deadweight of coal.
The purpose of this utility model is exactly for overcoming above-mentioned the deficiencies in the prior art, design a kind of energy fast, quantitatively, coal under the program, and can increase the coke oven coal-charging device of dump proportion.
The utility model is by the hyperbolic line coal bunker, and vertical spin mechanism and transmission rig are formed, and its principal feature is in the hyperbolic line coal bunker screw mechanism to be installed, and spiral 1 top is that banded pitch is less, and the bottom is that entity pitch is bigger, is complementary with hyperbolic line hopper 2.Vertical shaft 11 and bearing 4, tubular shafts bearing 5 are fixed on the bulkhead 3 by gusset 12.A pair of conical gear 10 is equipped with in vertical shaft 11 upper ends, and the other end of the conical gear that is meshed with it is installed on the transverse axis 8, links to each other with transmission rig step-down gear 7, change speed motor 6, forms the complete transmission mechanism of a cover.As long as starter motor just makes screw rotation, promotes the coal charge whereabouts, control blanking velocity like this,, during stall,, play the control action kou of stopping valve even the frictional force coal charge of helicoidal surface stops to move down because lead angle is less by changing motor speed.
When coking chamber needs coal, coal car is sailed to coke oven coal tower, open the sluices, the coal in the coal tower enters in the coal bunker.When reaching predetermined amount, close gate.Coal car drives towards coking chamber to be installed hole, to good position, take off bell, vertical spin drives rotation by drive unit, coal supply is with motivating force.Coaling with gravity and to compare, coal is except that the action of gravity that is subjected to vertically downward, and the power that also is subjected to being produced by screw drives has strengthened the whereabouts motion of extruding coal, and the bulk density of coal is increased, and has improved the coal amount.
This device has following advantage:
1, the advantage of coal under collection gravity and the spiral, can realize quantitatively, fast, coal under the program, helping realizing smokelessly coalingging the minimizing pollution.
2, can improve the bulk density of coalingging, increase the coal capacity of single hole stove, can increase production.
3, power consumption is few, has only about 1/3 of flat spin.
4, as long as the coal of having a surplus in the storehouse can be enclosed in flue dust, play the effect of valve.
5, suitability is strong, and existing coal charger can both be reequiped.Has more general promotional value.
6, simple in structure, compact, spiral top is band shape makes in the coal bunker coal charge uniform mixing more, also can destroy coal charge " bridge formation ", fluffy material, has avoided the putty phenomenon, has saved hopper wall vibrator or pressurized air is disclosed material.
Vertical spin technical parameter (is example with 4.3 meters coke ovens)
Revolution speed of screw: 10-15 rev/min
The speed of coalingging: 6 tons/minute (every bucket)
Power of motor: 4 kilowatts
Description of drawings: Fig. 1 is a Coke Oven Charging Car Vertical Spin Quantitative Blanking Apparatus.
1, spiral 2, hopper 3, feed bin 4, bearing 5, tubular shafts bearing 6 change speed motoies 7, step-down gear 8, transverse axis 9, umbrella gear box 10, conical gear 11, vertical shaft 12, gusset
