Abstract
The present invention relates to a coke oven cover made from fireproof materials, which is divided into a plurality of small strip-shaped double-arch covers; the curvature radii of the two arches are the same; the centers of circle of the curvature radii are respectively arranged in horizontal equidistant positions at both sides of the perpendicular bisector of arch tops of the small covers; the magnitude of the curvature radii and the horizontal distance of the perpendicular bisector and the two centers of circle need to ensure that the arch tops are positioned in the highest position of the oven covers. The small covers can be separately made from fireproof materials and can be simultaneously made from fireproof materials and thermal insulating materials. The oven cover has the advantages of no collapse and low cost for fabrication and repair.
Description
The present invention relates to a kind of lid for coke oven that is used on the pit kiln that refractory materials constructs.
Traditional Pingxiang stove (soil coke oven) does not have bell, and environmental pollution is big, and hot benefit is low, and coke quality is difficult to guarantee.
75 general type coking furnace roofs are provided with the bell of constructing with refractory materials integral body, though improved environmental pollution, but also brought disadvantages such as coal, compacting, quenching, the difficulty of the discharging of the coke, and the arch bell because thermal stresses is inhomogeneous the phenomenon of coke oven lid partial collapse often appears.
For addressing the above problem, CN 90207844 discloses a kind of movable bell that is made of heat resisting iron and embedded quarl, though in applying process, find again to a certain degree solving environmental pollution problems, and coal, compacting, quenching, the convenience of the discharging of the coke, initial cost is big, the burnt cost height of ton but also brought, disadvantages such as troublesome poeration.
The bell that a kind of refractory materials is constructed is disclosed among the CN95117431.2 " unit combination type up igniting coke oven and coking process thereof ", it is made of a plurality of small wave type vaults, be provided with register between two small form arches, apply and show, this arch bell caves in seriously, and the bell life-span is short, the thermal-insulating sealing poor performance, fire box temperature is difficult to guarantee, thereby has influenced the coke quality.
The objective of the invention is to develop a kind of not caving in and lid for coke oven that the thermal-insulating sealing performance is good.
The major technique feature of lid for coke oven of the present invention is: whole bell is divided into several bar shaped tegillums, dilatation joint is arranged between tegillum, each tegillum is made of two dome shaped cover, be that tegillum is two domes, described two arcual radius-of-curvature are identical, the garden heart of two radius-of-curvature splits in the horizontal equidistant in the both sides of whole bell vault midperpendicular, and the size of radius-of-curvature and the two garden hearts will guarantee that apart from the distance of midperpendicular described vault is in the vertex of whole bell.
Described dilatation joint is provided with the quenching hole near a side of furnace wall, seals in the carbonization process, opens during quenching.
The embodiment accompanying drawings of lid for coke oven of the present invention is as follows:
Fig. 1 is the synoptic diagram of two arch bells.
Fig. 2 is the bell overall schematic that places on the pit kiln.
Fig. 3 is the sectional schematic diagram of arch bell along radius-of-curvature.
As shown in the figure, 1 is left dome shaped cover, and 2 is right dome shaped cover, and 3 is dilatation joint, and 4 are the quenching hole, and 5 is flame retardant coating, and 6 is the thermal-insulating sealing layer, R

Described dome shaped cover 1 and 2, available refractory materials or flame-proof thermal insulation material integral body or split are fired, and can also be covered with the heat insulating sealing ply outside it near the side refractory materials in the stove.
The apparent advantage of the present invention is as follows:
1. long-time running is not caved in, and operation reaches that profile and structure are unchanged more than a year.
2. good thermal-insulating sealing performance is arranged, can make burner hearth keep best coking temperature, guaranteed The quality of coke has improved the thermal efficiency, has shortened coking time, has improved the production efficiency of stove.
3. can be used for the multiple type of furnace:
(1). can replace the whole bell of 75 type pit kiln to be used for 75 type pit kiln
(2). the bell that can replace unit combination type up igniting coke oven is also with in the above; Also can replace living
Moving bell.
4. initial cost is little, and maintenance cost is low, has reduced the burnt cost of ton.
Claims (4)
1. lid for coke oven that is used on the pit kiln that refractory materials constructs, it is characterized in that described bell vertically is divided into a plurality of pairs of arch tegillums along pit kiln, between described tegillum dilatation joint is arranged, two arch tegillums wherein are made up of two dome shaped cover, the radius-of-curvature of two dome shaped cover is identical, the garden heart of two radius-of-curvature splits in the horizontal equidistant in the both sides of whole bell vault midperpendicular, and the size of radius-of-curvature and the two garden hearts will guarantee that apart from the distance of midperpendicular top, described bell vault place is in the vertex of whole bell.
2. lid for coke oven as claimed in claim 1 is characterized in that in the both sides and the described dilatation joint intersection of the close furnace wall of bell the quenching hole being arranged.
3. lid for coke oven as claimed in claim 2 is characterized in that described pair of arch tegillum constructed by refractory materials integral body or split to form.
4. lid for coke oven as claimed in claim 2 is characterized in that described pair of arch tegillum is made of refractory materials near the side in the stove, and its outside is covered with the heat insulating sealing ply.
