Abstract
The invention relates to an oven door of a coke oven. The oven door comprises an oven door body, a propeller shaft, a spring door latch, an oven door lining brick and a jacking and pressing seat, wherein the oven door body is separately connected with the propeller shaft and the jacking and pressing seat; the propeller shaft is connected with the spring door latch, and a diaphragm plate knife edge is mounted between the oven door lining brick and the oven door body; a spring is arranged between the oven door body and the propeller shaft, the diaphragm plate knife edge comprises a knife edge frame, and a diaphragm plate is arranged in the knife edge frame; a folding edge is arranged on the periphery of the diaphragm plate, and is connected with the inner wall of the knife edge frame; a plurality of bolt holes are formed in the surface of the diaphragm plate, the diaphragm plate penetrates through the bolt holes through bolts to be connected with the lower end of the oven door body, and the jacking and pressing seat jacks and presses the diaphragm plate knife edge. The oven door disclosed by the invention is simple in structure, the sealing properties of the oven door of the coke oven is improved, the discharge of flue gas is reduced, the operating environment is improved, the labor intensity of workers is reduced, the environmental protection level of the coke oven is increased, the investment is low, the regulating range of the oven door is large, and the examining and repairing are convenient and quick.
Description
Technical field
The present invention relates to a kind of coke oven door, for sealing and keying capacity coke oven carbonizing chamber Two-port netwerk, belong to carbonizing chamber of coke oven opening and closing device technical field.
Background technology
Coke oven door extension set side fire door and two kinds, burnt side fire door are the equipment opening and closing coke furnace carbonization chamber Two-port netwerk. When fire door is closed, coking chamber and atmospheric isolation, when opening, pushing ram is released coke. Whether tight the sealing of fire door is smolders with preventing, burns with anger, protection of the environment and with firedoor frame, stove post distortion, lost efficacy have substantial connection. Existing 7.63 meters of coke ovens are the coke ovens that China's coking chamber height is the highest, single hole coking chamber volume is maximum at present, are the domestic advanced coke making process technology introduced from Germany, represent current coke making process technological development direction. Existing door structure is mainly by configuring spring keeper, fire door hanger bar, furnacing door lifting bar outside fire door main body, and the sealed knife limit of inner side configuration " Z " shape section, top water flat seat, fire door lining brick adopt pouring material, surrounding configuration push type broach side seat assembly. Coke oven pushing car and block burnt car by operation furnacing door lifting bar, biasing springs keeper, is suspended on firedoor frame by fire door, and coke furnace carbonization chamber port is closed; Hook furnacing door lifting bar, biasing springs keeper, mention and pull out fire door, coke furnace carbonization chamber port open. For guarantee sealing property, " Z " shape cutter limit is connected employing heat dress interference and connects with fire door main body, realizes the sealing of cutter limit and firedoor frame by the pressure of the push bolt on adjustment periphery push type broach side seat, spring. Due to fire door main body and cutter limit shrink range, to control difficulty in the fabrication process bigger, and " Z " shape cutter limit profile material straightness error and regulate time toughness less, during this Formed Coke Furnace production run gone into operation at home is put into practice, four, cutter limit fillet weld cracking phenomena is serious, generally exist between fire door knife edge and fire door body contact face and between cutter limit and firedoor frame trim smolder, phenomenon of running away, sealing weak effect, spare parts consumption amount is big, maintenance and maintenance load are big, have impact on the overall Environmental Protection Level of coke oven.
Summary of the invention
For above-mentioned defect, it is an object of the invention to provide a kind of good airproof performance, less investment, reliable a kind of coke oven door easy to maintenance, durable.
The technical solution adopted in the present invention is for this reason:
Comprise fire door main body, advance axle, spring keeper, fire door lining brick and top pressure seat composition, fire door main body is connected with propelling axle and top pressure seat respectively, advance axle and single or double acting door to tie to connect, between fire door lining brick and fire door main body, diaphragm plate cutter limit is installed, it is provided with spring between fire door main body and propelling axle, described diaphragm plate cutter limit comprises cutter side frame, it is provided with diaphragm plate in described blade framework, described diaphragm plate periphery is provided with flanging, described flanging is connected with cutter side frame inwall, described diaphragm plate surface is provided with some bolts hole, diaphragm plate is connected with the lower end of fire door main body by bolt passing through bolt hole, pressure diaphragm plate cutter limit, pressure seat top, top.
Described bolt hole is waist shaped hole.
The flanging direction of described diaphragm plate is towards fire door main body.
The flanging of described diaphragm plate adopts welding process to be connected with cutter side frame.
Described coke oven door can be used on 7.63 meters of coke ovens.
It is an advantage of the invention that:
Present configuration is simple, by adopting diaphragm plate cutter limit and be arranged between fire door lining brick and fire door main body, eliminate between conventional knives limit and fire door main body the leakage caused by tolerance clearance existed, invention increases the sealing property of coke oven door, decrease the discharge of flue gas, improve operating environment, reduce the labour intensity of workman, it is to increase the Environmental Protection Level of coke oven, less investment, fire door regulation range is big, overhauls convenient and swift.
