Abstract
The invention relates to the field of coke oven doors, and particularly relates to a novel coke oven door. The oven door comprises an iron groove, an upper transversal bolt, a lower transversal bolt, a hinge device, a slide plate, a knife edge web, a knife edge-pressing spring group, an oven door lining castable block and a guide block, wherein one end of the hinge device is connected with the iron groove, and the other end of the hinge device is connected with the slide plate. The oven door is characterized in that the section of the guide block is in an L shape, and one side edge of the guide block is connected with the iron groove via a bolt; a stop block I is arranged at one end, which corresponds to the hinge device, on the iron groove; a stop block II is arranged at the other end, which corresponds to the hinge device, on the slide plate. Compared with the prior art, the oven door disclosed by the invention has the following advantages that 1) the guide block is small in the occupied space, and knife edge-pressing springs are uniform in array, thus reducing air pollution and the labour intensity of workers; 2) the design types of the springs are reduced, thus machining, manufacture and installation are more easier; and 3) the stop blocks bear most of a shear force during picking up and hanging for the oven door, thus avoiding the occurrences of security incidents and ensuring the long-time stable production of the coke oven.
Description
Technical field
The present invention relates to coke oven door field, relate in particular to the new Type Coke Oven fire door of a kind of good airproof performance, safety and stability.
Background technology
In coke oven production process, need furnace retaining ironware to be protected coking furnace shaft, prevent the body of heater deformation effect coke oven life-span, wherein fire door is most important equipment in coke oven guarding iron system.In each coking cycles, coke oven door is seted out each once, and before coke pushing, fire door is taken from firedoor frame by pushing machine (or coke guide), and after coke pushing completes, fire door is suspended on firedoor frame again.Coke oven door not only plays the effect of protection body of heater, the more important thing is that fire door also plays the effect that sealing prevents that in stove, raw gas leaks.
Mainly there is following some drawback in traditional coke oven door:
1) the orienting lug cross section of fire door is T shape, adopt both sides bolt fastening structure, feature dimension is large, take up room many, cause fire door push type broach limit spring large at the arrangement pitch at orienting lug place, knife-edge discontinuity, easily causes raw gas in stove to leak in atmosphere, fire door is smoldered and is burned with anger, and causes atmospheric pollution and has increased workman's labour intensity;
2) because of push type broach limit spring skewness, cause spring model numerous, cause processing and manufacturing and difficulty is installed, increased the maintenance cost of production and coke oven and workman's labour intensity;
3) the dependence articulated mounting such as fire door liner in pouring material piece, slide plate, knife-edge web is connected on fire door metal trough, when seting out fire door operation, the weight of fire door liner in pouring material piece, slide plate, knife-edge web etc. is delivered on the joint bolt at articulated mounting two ends by the connecting rod of articulated mounting, joint bolt bears very large shearing force because of prolonged and repeated, easily cut off or threaded off, cause fire door liner in pouring material piece, slide plate, knife-edge web etc. to come off from metal trough, lead to security incident.
Summary of the invention
The object of this invention is to provide a kind of new Type Coke Oven fire door, overcome the deficiencies in the prior art, require good seal performance, be convenient to make processing, reduce labor strength, can reduce security incident, make the coke oven production that maintains a long-term stability.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of new Type Coke Oven fire door, comprise metal trough, upper cross bolt, lower cross bolt, articulated mounting, slide plate, knife-edge web, push type broach limit spring assembly, fire door liner in pouring material piece and orienting lug, articulated mounting one end is connected with metal trough, the articulated mounting the other end is connected with slide plate, described orienting lug cross section is L shaped, and a side of orienting lug is connected with metal trough by bolt.
Described orienting lug is provided with stiffening web.
On described metal trough, one end of corresponding articulated mounting is provided with block one.
On described slide plate, the other end of corresponding articulated mounting is provided with block two.
Compared with prior art, the invention has the beneficial effects as follows:
1) the one-sided bolt fastening structure of orienting lug, institute takes up space little, and fire door push type broach limit spring is arranged evenly, knife-edge is stressed evenly, make raw gas in stove be difficult for leaking in atmosphere, reduced the phenomenon of burning with anger of smoldering of fire door, alleviated atmospheric pollution and workman's labour intensity;
2) push type broach limit spring is arranged evenly, and the design model of spring is reduced, and processing and manufacturing and installation are become easily, has reduced the maintenance cost of coke oven;
3) on metal trough and slide plate, block is set, make articulated mounting one end and metal trough junction, the articulated mounting the other end and slide plate junction, when dislodging fire door, block is born most shearing force, be difficult for being cut off or threading off, the possibility that fire door liner in pouring material piece, slide plate, knife-edge web etc. are come off from metal trough reduces greatly, has avoided the generation of security incident, has guaranteed coke oven production steady in a long-term.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
See Fig. 1 to Fig. 7, it is a kind of new Type Coke Oven fire door of the present invention example structure schematic diagram, comprise metal trough 1, upper cross bolt 2, lower cross bolt 3, articulated mounting 4, slide plate 5, knife-edge web 6, push type broach limit spring assembly 7, fire door liner in pouring material piece 8 and orienting lug 9, articulated mounting 4 one end are connected with metal trough 1, articulated mounting 4 the other ends are connected with slide plate 5, orienting lug 9 cross sections are L shaped, and a side of orienting lug 9 is connected with metal trough 1 by bolt.Orienting lug 9 is provided with stiffening web 13, to improve shear strength.In order to improve the shear strength of articulated mounting 4, on metal trough 1, one end of corresponding articulated mounting 4 is provided with block 1, and on slide plate 5, the other end of corresponding articulated mounting 4 is provided with block 2 11.
While plucking fire door, by being arranged on the keying road door gear on pushing machine (or coke guide), fix and lift upper cross bolt 2 and lower cross bolt 3, drive metal trough 1 to move upward, metal trough 1 and then drive slide plates 5, knife-edge web 6 to move upward together with fire door liner in pouring material piece 8 by articulated mounting 4, make fire door from firedoor frame 12 throw off and pluck from.
The above-mentioned fire door process of plucking of process that fire door is suspended on firedoor frame is contrary.
After fire door is suspended on firedoor frame 12, push type broach limit spring assembly 7 applies a constant power to knife-edge web 6, makes knife-edge web 6 closely oppress the trim of firedoor frame 12, thereby play the sealing to coking furnace shaft, prevents the effect that raw gas leaks.
