Description
Technical field:
The utility model relates to the cement slurry delivery system, belongs to the cement clinker production field.
Background technology:
In existing cement slurry production process, homogenizing storehouse storage capacity is less, the homogenizing ability a little less than, go out homogenizing storehouse and adopt the monobucket lifting, cause into temperature booster raw material homo-effect poorly, the raw ingredients fluctuation is larger, for the calcining of follow-up grog, causes very large difficulty.And to adopt the scheme of independent transformation raw material homogenizing silo, cost of investment is larger, and the transformation cycle is longer.Raw material after homogenizing enter raw material silo, directly give the temperature booster feeding by air lift mud pump again, raw material silo does not have gauging device, so the raw material amount in storehouse can't be learnt in time, be easy to cause the phenomenon of buying securities with all one's capital in operating process, can stop up raw material silo top transfer line when serious; The air lift mud pump pump housing is tall and big, takes up room more, and power consumption is also larger, and the hoisting capacity of air lift mud pump is limited, seriously restricts the output of whole production system, causes output on the low side; And while using air lift mud pump, can not continue feeding once preheater section generation putty and breakdown of equipment, the material promoted will fall down suddenly in riser tubing, cause solid accumulation below riser tubing, need a large amount of time and manpowers to be dredged, when serious, the material riser tubing of can scurrying out causes a large amount of airborne dusts and the damage of lift pump motor.
The utility model content:
The purpose of this utility model is to provide a kind of homogenizing ability that increased, and improves the homogenization degree of raw material, shortens the floor time that barrier causes for some reason, and reduces the cement slurry delivery system of settlement of accident manpower.
The utility model is implemented by following technical scheme: the cement slurry delivery system, it comprises that homogenizing storehouse, two bucket elevators, raw material homogenizing measuring chute, speed governing constant feeder, revolving plow reclaimer, steel wires twist band gig, electronic positive threeway scraper-trough conveyer and auger loader, wherein, described homogenizing storehouse discharging opening is connected with the inlet point of two described bucket elevators; The discharging opening of two described bucket elevators is connected with the inlet point of described raw material homogenizing measuring chute, and the discharging opening of described raw material homogenizing measuring chute is connected with the inlet point of described speed governing constant feeder; Be provided with described revolving plow reclaimer between the inlet point of the discharging opening of described raw material homogenizing measuring chute and described speed governing constant feeder; The discharging opening of described speed governing constant feeder is connected with the inlet point of described steel wire strand with gig; Be provided with described electronic positive threeway scraper-trough conveyer on the discharging opening of described steel wire strand with gig, two discharging openings of described electronic positive threeway scraper-trough conveyer are connected with described auger loader inlet point with described homogenizing storehouse inlet point respectively.
Described raw material homogenizing measuring chute comprises measuring chute main body, two adjustable speed damping screw mixers and load sensor, be provided with two described adjustable speed damping screw mixers in described measuring chute main body, on described measuring chute main body outer wall, be provided with described load sensor.
Advantage of the present utility model: adopt twin-bucket lifting raw material, increased the homogenizing ability, and install original raw material silo additional band spiral agitator and load sensor, stop to buy securities with all one's capital and stop up the phenomenon of transfer line, again strengthen the homogeneization to raw material, improve the homogenization degree of raw material, stay-in-grade raw material are provided to follow-up calcining; After using this system, the problem of raw ingredients fluctuation thoroughly solves, and clinker quality significantly promotes; Efficient steel wire strand band Structure of hoist is simple, low cost of manufacture, and small investment, hoisting depth is high, and hoisting capacity is large, and, because the steel wire rope rubber band strength is large, makes this elevator system operate steadily, and electricity consumption of equipment power is little, few easy workout part, maintenance cost is low; And after adopting efficient steel wire strand band gig; once outage or equipment occur mediates; logistics is still stayed in the elevator bucket in gig so; can not cause material to fall to stopping up delivery system; joint shortens the floor time that barrier causes for some reason greatly, and has reduced the manpower of settlement of accident, and this gig is furnished with stop device; by the effect of stop device, equipment can not reverse and cause the situation of damage driving motor and reductor.This plant maintenance and troubleshooting effort are simple, generally only need 1-2 name personnel can operate and trouble-shooting.And this equipment is provision for sealing, the situation of can not cause airborne dust, running the serious environment pollutions such as material.Fill electronic positive threeway scraper-trough conveyer at steel wire strand band gig end, the material in gig can return in homogenizing storehouse by electronic positive another exit passageway of threeway scraper-trough conveyer; Whole raw material conveyor system forms the system of a self-loopa; once temperature booster generation putty or fault; raw material in load transfer device can loop back raw material homogenizing silo in time, and when the homogenizing warehouse compartment allows, raw material preparation system is also without shutting down for a long time because of faults of preheater.
