Abstract
The invention relates to a knife edge for a coke oven door, wherein the knife edge comprises a knife edge frame made of flat steel; a diaphragm plate is arranged in the knife edge frame; a fold 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 connected with a main oven door body are formed in the surface of the diaphragm plate; a knife-edge sealing edge is arranged on the outer wall of the lower end of the knife edge frame. The knife edge for the coke oven door is simple in structure, smoke-tight, durable and reliable, and good in sealing effect because the cracking phenomenon of four corners of the knife edge is avoided by connecting the fold edge of the diaphragm plate with the knife edge frame.
Description
Technical field
The present invention relates to a kind of coke oven door knife-edge, belong to carbonizing chamber of coke oven opening and closing device technical field.
Background technology
Coke oven door extension set wing furnace door and two kinds of coke side fire door, be the equipment opening and closing coke furnace carbonization chamber Two-port netwerk. When fire door is closed, carbonization chamber and atmospheric isolation, when opening, pushing ram is released coke. The sealing of fire door whether tight with prevent from smoldering, burning with anger, protection environment and with firedoor frame, furnace stay deformation, inefficacy close relation. Existing 7.63 meters of coke ovens are the current China coke ovens that carbonization chamber height is the highest, single hole carbonization chamber volume is maximum, 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, the inner side configuration sealing knife-edge of Z-shaped section, upper water flat seat, fire door lining brick adopt pouring material, surrounding configuration push type broach side seat assembly. Coke oven pushing car and coke guide are operated by furnacing door lifting bar, biasing springs keeper, are suspended on firedoor frame by fire door, coke furnace carbonization chamber port shutdown; Hook furnacing door lifting bar, biasing springs keeper, mention and pull out fire door, coke furnace carbonization chamber port open. For ensureing sealing property, Z-shaped knife-edge is connected by hot charging interference with fire door main body and is connected, and realizes the sealing of knife-edge and firedoor frame by the pressure of the hold-down bolt on adjustment periphery push type broach side seat, spring. Due to fire door main body and the knife-edge magnitude of interference, to control difficulty in the fabrication process bigger, and toughness is less when Z-shaped knife-edge profile material straightness error and adjustment, in this Formed Coke Furnace production run practice gone into operation at home, four angle welding cracking phenomenas of knife-edge are serious, between fire door knife edge and fire door body contact face and between knife-edge and firedoor frame sealing surface ubiquity smolder, phenomenon of running away, sealing effectiveness is poor, spare parts consumption amount is big, safeguard and maintenance load is big, have impact on the overall Environmental Protection Level of coke oven.
Summary of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple in construction, good airproof performance, do not run cigarette and durable reliable a kind of coke oven door knife-edge.
For this technical solution adopted in the present invention it is:
Including the knife-edge framework that band steel is made, being provided with diaphragm plate in described knife-edge framework, described diaphragm plate periphery is provided with flanging, and described flanging is connected with knife-edge frame inner wall, described diaphragm plate surface is provided with some bolts hole being connected with fire door main body, and knife-edge framework lower end outer wall is provided with edge seal limit.
Bolt hole of the present invention is waist-shaped hole.
The flanging direction of diaphragm plate of the present invention is contrary with edge seal limit.
The flanging of diaphragm plate of the present invention adopts welding manner to be connected with knife-edge framework.
The invention have the advantage that
Present configuration is simple, by adopting diaphragm plate flanging and knife-edge framework connected mode, it is to avoid knife-edge corner cracking phenomena, thus good airproof performance, do not run cigarette and durable reliably.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional view of Fig. 1.
Figure 1 is knife-edge framework, 2 is diaphragm plate, 3 is flanging, 4 is bolt hole, 5 is edge seal limit.
Detailed description of the invention
A kind of coke oven door knife-edge, including the knife-edge framework 1 that band steel is made, it is provided with diaphragm plate 2 in described knife-edge framework 1, described diaphragm plate 2 periphery is provided with flanging 3, described flanging 3 is connected with knife-edge framework 1 inwall, described diaphragm plate 2 surface is provided with some bolts hole 4 being connected with fire door main body, and knife-edge framework 1 lower end outer wall is provided with edge seal limit 5.
Bolt hole 4 of the present invention is waist-shaped hole.
Flanging 3 direction of diaphragm plate 2 of the present invention is contrary with edge seal limit 6.
The flanging 3 of diaphragm plate 2 of the present invention adopts welding manner to be connected with knife-edge framework 1.
