Abstract
The utility model relates to the field of coke oven doors, and particularly discloses a novel coke oven door. The novel coke oven door comprises an iron groove, an upper horizontal bolt, a lower horizontal bolt, a hinge assembly, a sliding plate, a knife edge web plate, a pushing knife side spring group, an oven door liner pouring block and a guiding block, wherein one end of the hinge assembly is connected with the iron groove, and the other end of the hinge assembly is connected with the sliding plate; the novel coke oven door is characterized in that the section of the guiding block is L-shaped, and one side edge of the guiding block is connected with the iron groove through bolts; and one end of the iron groove, corresponding to the hinge assembly, is provided with a stop dog I, and the other end of the sliding plate, corresponding to the hinge assembly, is provided with a stop dog II. Compared with the prior art, the novel coke oven door provided by the utility model has the advantages that (1) the occupying space of the guiding block is small, the pushing knife side springs are uniformly arranged, and the air pollution and labour intensity of workers are lightened; (2) the design types of the springs are reduced, and the processing and manufacturing and installation are easy; and (3) the stop dog can bear most shear force when the over door is set, accident is avoided, and a coke oven is guaranteed to stability run for a long time.
Description
Technical field
The utility model relates to the coke oven door field, relates in particular to the new Type Coke Oven fire door of a kind of good airproof performance, safety and stability.
Background technology
In the coke oven production process, need the furnace retaining ironware that coking furnace shaft is protected, prevent the body of heater deformation effect coke oven life-span, wherein fire door is most important equipment in the 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 was completed, fire door was 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 the 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, the knife-edge discontinuity causes easily that in stove, raw gas leaks 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 the 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 mountings such as fire door liner in pouring material piece, slide plate, knife-edge web are connected on the fire door metal trough, when seting out the 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 purpose of this utility model is to provide a kind of new Type Coke Oven fire door, overcomes the deficiencies in the prior art, requires good seal performance, is convenient to make processing, reduces labor strength, can decrease safent accident, make the coke oven production that maintains a long-term stability.
For achieving the above object, the utility model 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, an 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 beneficial effects of the utility model are:
1) the one-sided bolt fastening structure of orienting lug, institute takes up space little, makes the limit spring arrangement of fire door push type broach evenly, knife-edge is stressed evenly, make the interior raw gas of 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 spring design model 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, block is born most shearing force when the dislodging fire door, be difficult for being cut off or threading off, the possibility that makes fire door liner in pouring material piece, slide plate, knife-edge web etc. 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, embodiment of the present utility model is described in further detail.
See Fig. 1 to Fig. 7, it is a kind of new Type Coke Oven fire door of the utility model 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 ends 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, an end of corresponding articulated mounting 4 is provided with block 1 on metal trough 1, and the other end of corresponding articulated mounting 4 is provided with block 2 11 on slide plate 5.
When 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, driving metal trough 1 moves upward, metal trough 1 and then drive slide plates 5, knife-edge web 6 and fire door liner in pouring material piece 8 by articulated mounting 4 and move upward together, 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 opposite.
After fire door was suspended on firedoor frame 12, push type broach limit spring assembly 7 applied a constant power for knife-edge web 6, makes knife-edge web 6 closely oppress the trim of firedoor frame 12, and sealing prevents the effect that raw gas leaks to coking furnace shaft thereby play.
