Technical Field
The utility model belongs to the technical field of the sediment is arranged to the buggy stove, especially, relate to an automatic ash discharge system of buggy stove.
Background
The coal powder furnace can generate a large amount of ash slag after combustion, the ash discharge of the existing coal powder furnace is realized by regularly discharging ash from a scraper conveyor, directly discharging the ash from an ash outlet of the scraper conveyor onto an ash pushing trolley, and manually pushing the ash onto a slag warehouse; the ash in the slag storage is carried away by a truck; because the ash produced by the pulverized coal furnace can be mixed with the condensed water outside the boiler, the water content of the transported ash is high, so that the transportation cost of manually pushing the ash is increased, and the ash is easy to spill out in the transportation process to pollute the environment, so that an automatic ash discharging device needs to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an effectual problem among the above-mentioned background of solution has proposed an automatic ash discharge system of buggy stove, and concrete technical scheme is as follows:
an automatic ash discharging system of a pulverized coal furnace comprises a slag discharging groove (2) connected with a scraper (1), wherein the slag discharging groove (2) is communicated with an ash pool (3), one end of the ash pool (3) is connected with a clean water pool (4) for injecting water into the ash pool (3), the other end of the ash pool (3) is connected with a drum-type dehydrator (5), and the water outlet end of the drum-type dehydrator (5) is connected with the clean water pool; the device is characterized in that a slag flushing pump (6) for flushing the ash pool (3) and a circulating pump (7) for absorbing the waste water discharged by the drum-type dehydrator (5) are arranged in the clean water pool (4), and a spiral conveyor (8) is arranged at the lower end of the drum-type dehydrator (5).
Preferably, a filter screen (9) is arranged between the clean water tank (4) and the ash water tank (3), and a stirring rod (10) for mixing the pulverized coal and the water is arranged in the ash water tank (3).
Preferably, a slurry pump (11) and a dosing tank (12) for accelerating the separation of the mixture materials are arranged between the ash water tank (3) and the drum-type dehydrator (5).
Preferably, the front ends of the mud pump (11) and the dosing tank (12) are respectively provided with a flowmeter (13)
Compared with the prior art, the beneficial effects of the utility model reside in that: this device is direct with exhaust ash material and water stirring to separate ash material and water through drum-type hydroextractor, be the water cyclic utilization of separation, through mixing the ash material with water after the transportation, at the process of separation loading, guaranteed that the ash material can not fly away at the in-process of transportation and cause environmental pollution, simultaneously for the ash material of graininess or piece dress, the mud after the mixture more conveniently transports through the drive of the pump body.
