Slot and bury scraper plate discharge of the coke machine 11 formed tapping channel.
The working principle of the utility model are as follows:
Coking process are as follows: the Pyrolysis Char of red heat successively passes through water-cooling wall and economizer, reaches reciprocating ram 5, past
Compound ram 5 scrapes half defocused, and semicoke falls through into collection coke bin 7 due to gravity naturally.Coking process is using upper gate valve 8 under
Gate valve 10 controls.Upper gate valve 8 and lower gate valve 10 are always in the alternate position of opening and closing；When coke discharging, first close on intermediate buffering storehouse 9
Gate valve 8(valve is connected with collection 7 bottom of coke bin in portion), the lower subordinate's gate valve 10 in intermediate buffering storehouse 9 is opened after the completion of coke discharging, by semicoke
Discharge.When semicoke is not discharged, lower subordinate's gate valve 10 is in the closed position, and gate valve 8 is in the open position on top, collection coke bin 7
Semicoke drops down onto intermediate buffering storehouse 9.This switch system can guarantee harvesting and storing and being discharged for material, and guarantee that coal gas is not from bilayer in furnace
Valve leakage.
Concrete operations are: as ceaselessly horizontal reciprocating moves ram 5, the Pyrolysis Char (about 500 DEG C ~ 600 of red heat
DEG C) constantly move down from carbonization furnace 1 from the discharge of coke discharging mouth, water-cooling wall 2 and economizer 3 are sequentially entered, red coke exists
By the medium heat release into pipe of water-cooling wall 2 in dropping process, temperature is down to 300 ~ 350 DEG C after semicoke exchanges heat with water-cooling wall 2, semicoke
Exchanging heat with economizer 2 into pipe, temperature is down to 150 ~ 200 DEG C or so after medium heat release, then reaches ram 5, and ram 5 is scraped
Half is defocused out, and semicoke is since gravity falls through into collection coke bin 7 naturally, at this point, being first shut off subordinate's gate valve under intermediate buffering storehouse 9
10, gate valve 8 on 9 top of intermediate buffering storehouse is opened, semicoke enters intermediate buffering storehouse 9, when intermediate surge bunker 9 stores certain semicoke
Afterwards, gate valve 8 on top is closed, the lower subordinate's gate valve 10 in intermediate buffering storehouse 9 is opened, semicoke falls through into semicoke by intermediate buffering storehouse 9
Chute, discharges of the coke machine 11 into furnace bottom, and the machine 11 that discharged of the coke is transported into semicoke stockyard.During this, gate valve 8 and lower subordinate on top
Steam blowing can be led at gate valve 10, prevent furnace gas from leaking outside, collect coke bin 7 and intermediate buffering storehouse 9 is also provided with intermittent shower water pipe, depending on life
Situation is produced to assist controlling temperature of the discharging of the coke, guarantees that back strap transportation system is unlikely to because overheating the tenability limit more than belt.
