A kind of semicoke coke discharging technique, this process using up and down twice have the coke discharging valve of lock airway dysfunction, and adopt the cooled coke discharge box between the twice coke discharging valve, and described cooled coke discharge box adopts water-cooling jacket and nitrogen sealing gland.
But described coke discharge box top coke discharging valve adopts the multistage form spiral coke discharging valve of continuous uniform coke discharging, and multistage form spiral coke discharging valve is comprised of several form coke discharging teeth and coke discharging axle, and several form coke discharging teeth are serially connected with 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.
Described cooled coke discharge box bottom coke discharging valve adopts the form feed valve.
The chain conveyor of described cooled coke discharge box bottom is provided with the closed shell structure.
Described cooled coke discharge box sidepiece is provided with upper level gage, meta level gage, the next level gage.
Compared with prior art, the invention has the beneficial effects as follows:
1) to the high-valued cracking utilization of low-rank coal, has wide industrial application prospect, remarkable in economical benefits;
2) effectively overcome the drawback of the inapplicable pulverulent material of traditional vertical type pit kiln, so that become possibility with upright furnace production semicoke;
3) it is obvious that water-cooling jacket and nitrogen air seal set reduce semicoke coke discharging temperature effect;
4) upper and lower twice have coke discharging valve and the stock column sealing of lock airway dysfunction, and are aided with nitrogen-sealed, have guaranteed the complete secluding air of coking chamber, guarantee the safety of production process;
5) three level gages in upper, middle and lower are effectively controlled the charge level height of cooled coke discharge box, make the material envelope more reliable;
6) the sealing chain conveyor has solved the airborne dust problem when effluxing semicoke.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See Fig. 1, it is the structural representation of semicoke coke discharging technique, be provided with multistage form spiral coke discharging valve 1 on the top of cooled coke discharge box 2, the structure of described multistage form spiral coke discharging valve 1 can make the powdery semicoke along axially evenly the draining in the cooled coke discharge box 2 of multistage form spiral coke discharging valve 1, effectively overcomes the bulkhead effect.The rotating speed of described multistage form spiral coke discharging valve 1 is set according to the semicoke coking time.The gear gabarit of described multistage form spiral coke discharging valve 1 and housing form an enclosed space, and secluding air upwards enters coking chamber effectively.
Be provided with form coke discharging valve 10 in the bottom of cooled coke discharge box 2, the structure of described form coke discharging valve 10 can make semicoke drain into faster chain conveyor 5.When upper level gage 7 triggers, described form coke discharging valve 10 quick coke dischargings; When meta level gage 8 triggers, described form coke discharging valve 10 low speed coke dischargings; When the next level gage 9 triggered, described form coke discharging valve 10 stopped coke discharging.
