Abstract

The utility model provides a pin wheel rim drive automatic ash disposal coal gas producer. The fire-resistant wall is a furnace shell provided with a water jacket, wherein the top part of the furnace shell is provided with a coal-hatch; The upper part of the internal surface of the fire-resistant wall is provided with a lateral windshield board; the lower part of the internal surface of the fire-resistant wall is provided with a steel jacket; the pinions connected with the electromotor contact the barbed nails between the pin wheels; a slag-breaking firebar provided with a slag hammer is fixed on the pin wheels; slideways are fixed below the pin wheels; steel balls are arranged between the slideways; cone-shaped funnels are connected to the bottom parts of the slideways. As the utility model adopts the above-mentioned structure, the pin wheels transmit the force stably and are capable of bearing great torque force and shearing force; chute balls are adopted to support the rim drive, thereby the combustion of coal is uniform without coking or scarring, the gas yield is improved, automatic ash discharge is achieved, the operation and maintenance are more convenient, and the energy consumption is reduced.

Description

Pin wheel edge transmission automatic ash-discharging producer gas generator

Technical field

The utility model relates to the mechanical transmission of coal chemical technology, and particularly the used Gas-making Furnace of coal gas is produced in industry, and this stove is mainly collected carbon monoxide, with other industrial chemicals reaction. as the sodium formiate production line.

Background technology

At present, producer gas generator adopts static fire bars directly to carry coal and produces carbon monoxide, its structure is by the gas collection mouth, charcoal-adding opening, stove outer covering, refractory wall, water jacket, blast inlet/ash output hole, blower fan, help the airduct road, the self-priming blast inlet, major partss such as fire bars are formed. and its working process adds raw coal by charcoal-adding opening, lower floor is a cinder layer, be in the ash discharge state for the treatment of, the middle level is that heat zone is in state of combustion, the upper strata is a run of mine coal seam, be in the combustion state for the treatment of, lower floor was through more than the ten hours intact gas of sufficient combustion system, can manually unload ash from blast inlet/ash output hole utilization, a small amount of ash of part falls from the fire bars slit, is gone out clearly by the self-priming blast inlet.Coal gas is collected from the gas collection mouth, finishes system gas whole process, blower fan, helps the airduct road when the special requirement shutdown maintenance, work when lighting a fire again, the after wind office of igniting, blower fan place normally off under the ordinary production situation.The shortcoming of its existence: the self-priming blast inlet is a side air intake, and airborne oxygen is gone up when inhaling automatically, skewness, and it is insufficient to burn, and coal utilizaton rate is low; When opening blast inlet/ash output hole, place, coal seam limit wind is excessive around its mouthful, and easily coking scabs, and hard and diameter is at 300-500MM, and it is very big manually to unload grey difficulty, influences the gas making time, inefficiency.By analysis, if blower fan 24 continuous throughout the twenty-four hour24s, loss so increases electric power.In addition, slow excessively because of artificial ash discharge, the fire bars place condition of high temperature reduces working life greatly.

Summary of the invention:

The purpose of this utility model provides a kind of sufficient combustion, noncoking, does not scab, the pin wheel edge transmission automatic ash-discharging producer gas generator of high efficiency.

The purpose of this utility model is achieved in that refractory wall is the stove outer covering of band water jacket outward, coal filling hole is arranged at stove outer covering top, the refractory wall upper inside wall has limit wind plate washer, steel bushing is arranged at refractory wall inwall bottom, pin finger between the pinion(gear) contact pin wheel that motor connects, the break fire bars that has the break tup is fixed on the pin wheel, and slideway is fixed under the pin wheel, steel ball is arranged between the slideway, be connected with conical hopper below the slideway.

Because the utility model adopts said structure, the pin wheel power transmission is steady, can carry bigger distortion, shearing force, adopt the transmission of slideway steel ball revolution bearing edge, make coal combustion even, and noncoking, do not scab, improve gas production rate, reach automatic ash discharge, make things convenient for the workman to operate, maintenance is convenient, and is energy-saving and cost-reducing.

Description of drawings

Fig. 1 is a structure iron of the present utility model.

1 pinion(gear), 2 motors, 3 slideways, 4 steel balls, 5 pin wheels, 6 break fire bars, 7 break tups, 8 steel bushings, 9 refractory walls, 10 stove outer coverings, 11 coal filling holes, 12 water jackets, 13 limit wind plate washers, 14 pin fingers, 15 conical hoppers among the figure

Embodiment

Embodiment: be the stove outer covering 10 of band water jacket 12 outside the refractory wall 9, coal filling hole 11 is arranged at stove outer covering 10 tops, refractory wall 9 upper inside wall have limit wind plate washer 13, steel bushing 8 is arranged at refractory wall 9 inwall bottoms, pin finger 14 between the pinion(gear) 1 contact pin wheel 5 that motor 2 connects, the break fire bars 6 that has break tup 7 is fixed on the pin wheel 5, and slideway 3 is fixed on pin wheel 5 times, steel ball 4 is arranged between the slideway 3, be connected with conical hopper 15 below the slideway 3.

The type of drive that design is adopted is the 4 revolution bearing edge transmissions of slideway 3 steel balls; pinion(gear) 1 pin wheel 5 under the propulsion source effect of motor 2 drives break fire bars 6, break tup 7; utilize the deadweight of coal in the stove axially to move down; circumference is motionless; the rotation of furnace bottom produces friction, fragmentation under the effect of break tup 7, make cinder fall conical hopper 15 in the gap of break fire bars 6; ash under finishing automatically, 8 pairs of refractory walls 9 of steel bushing, stove outer covering 10 shield.

Pin wheel 5 transmissions, power transmission is steady, can carry bigger distortion, and shearing force, and convenient maintenance are changed pin finger 14, and be economical and practical; Design the up-small and down-big certain taper shape that has at refractory wall 9 internal diameters, different sites is established limit wind plate washer 13, and effectively anti-limit wind is excessive, makes burning evenly; Slideway 3, steel ball 4 its essence is that a kind of weight mechanical axis holds, and can carry axle pressure and radial location; Conical hopper 15 is main blast inlets, also is automatic ash output hole, and center cloth wind improves gas production rate.

Claims

1, a kind of pin wheel edge transmission automatic ash-discharging producer gas generator, refractory wall is outward the stove outer covering of band water jacket, coal filling hole is arranged at stove outer covering top, the refractory wall upper inside wall has limit wind plate washer, and steel bushing is arranged at refractory wall inwall bottom, it is characterized in that: the pin finger between the pinion(gear) contact pin wheel that motor connects, the break fire bars that has the break tup is fixed on the pin wheel, slideway is fixed under the pin wheel, and steel ball is arranged between the slideway, is connected with conical hopper below the slideway.
