A kind of multistage form spiral coke discharging valve is characterized in that this device is comprised of several form coke discharging teeth, and several form coke discharging teeth are arranged on the coke discharging axle; Each form coke discharging tooth comprises coke discharging tooth and dividing plate, and coke discharging tooth, dividing plate and coke discharge box housing form the closed cell with lock gas and even discharge effect, is the coke discharging passage between the coke discharging tooth; Two coke discharging teeth of the adjacent installation of two form coke discharging teeth certain angle that staggers, coke discharging tooth bus are spiral-line and distribute.
This device is provided with ratchet and pawl, and described ratchet can be driven by hydro-cylinder or other power set, and ratchet matches with ratchet, and ratchet is fixed on the coke discharging axle; Also can drive the coke discharging axle by motor, step-down gear and drive multistage form spiral coke discharging valve.
Coke discharging tooth on described each form coke discharging tooth evenly distributes.
The both sides of described multistage form spiral coke discharging valve are provided with to support uses bearing.
The rotating speed of described multistage form spiral coke discharging valve can according to the manufacturing technique requirent of semicoke, be adjusted by regulating hydraulic fluid flow rate or motor speed.
Compared with prior art, the invention has the beneficial effects as follows:
1) multistage form spiral coke discharging valve of the present invention has the spirane structure of unit sealing, multistage coke discharging tooth, adapts to especially the characteristic of semicoke or other small grain size coke product, and flow control is more stable, has extraordinary air-tightness;
2) can be the evenly controlled discharge semicoke of multistage form spiral coke discharging valve, and effectively solve the bulkhead effect;
3) effectively overcome the drawback of the inapplicable pulverulent material of traditional vertical type pit kiln, so that become possibility with upright furnace production semicoke;
4) to the high-valued cracking utilization of low-rank coal, has wide industrial application prospect, remarkable in economical benefits.
