Abstract
The utility model relates to a fire coal processing device used in the production of fossil-fired power plants, in particular to a purging type pebble coal discharging device for processing pebble coal in fire coal, which comprises a valve body installed between a pebble coal hopper and a delivery mechanism and a flash-board which is matched with the valve body to open and close the channel of the valve body, wherein the flash-board is driven by actuating mechanisms, such as a motor or a hydraulic cylinder and the like, the inner wall of the valve body is provided with groove rails which are matched with the flash-board, an air bag is arranged outside the valve body, and the air outlet of the air bag is led to the groove rails through a hole channel of the valve body, and the air inlet of the air bag is connected with a gas source through an electromagnetic valve. The purging type pebble coal discharging device can purge dust and slag in the groove rails of the valve body by impulse air flow in the closing process of the flash-board through arranging an impulse purging device on a traditional flash-board valve, guarantees the full closedown of the flash-board, and increases the closedown reliability.
Description
Technical field
The utility model relates to the coal-fired processing equipment that uses in the production of a kind of thermal power plant, specifically is a kind of sweeping type pebble coal dumping device that stone coal in the fire coal is handled.
Background technique
Power plant handles in the journey at fire coal, can produce a large amount of stone coals during medium-speed pulverizer work, these stone coals that are stored in the hopper need periodically to be discharged into conveying equipment by discharge mechanism, existing discharge mechanism generally includes a gate valve that is made of valve body and flashboard, by the open and close controlling discharge process of gate valve.In its working procedure, the grooved rail that cooperates with flashboard in the body cavity is not closed completely flashboard in often having dust and expecting that slag remains in, and has influenced the normal operation of coal pulverizer, also causes the leakage pollution of dust.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, can clean valve cavity automatically, valve seals reliable sweeping type pebble coal dumping device.
Sweeping type pebble coal dumping device of the present utility model includes a flashboard of closing or open valve channel that is installed in the valve body between stone coal hopper and the conveying equipment and cooperates with valve body, flashboard is driven by actuators such as motor or oil hydraulic cylinders, valve interior wall is provided with the grooved rail that cooperates with flashboard, it is characterized in that: a gas bag is arranged in the valve body arranged outside, the air outlet of gas bag is led in the above-mentioned grooved rail through the duct on the valve body, and the suction port of gas bag is connected with source of the gas by an electromagnetic impulse valve.Rounded or the rectangle of the intracavity section of described valve body, corresponding flashboard shape also adapts with it.
The utility model is owing to be provided with the pulse blowing cleaner on traditional gate valve, thereby can flashboard close utilize on the closed procedure pulsing airflow to the dust in the valve body grooved rail and the material slag purge cleaning, having guaranteed that flashboard can cut out puts in place, has improved the reliability of sealing.
