Description

Cover of coke-oven

The utility model has related to a kind of enclosed appts that is used for the pit kiln constructed by refractory materials, is specially a kind of pit kiln bell to be opened/closed.

At present, use many soil coke ovens in China, from top construction, roughly comprise two big classes, spacious top formula of one generic or non-cover type, with Pingxiang stove is representative, this type of furnace is feeded and is discharged of the coke more convenient, shortcoming is that burning is uneven, coke quality instability, pay product such as tar, the coal-gas recovering utilization ratio is low, cause very serious pollution, in order to overcome above-mentioned deficiency, in recent years design a kind of soil coke oven again with top construction, also claim closed pit kiln, as Chinese patent CN87212113U disclosed a kind of " pit kiln ", its formation is to support an arch form furnace roof of being constructed by same material by the four sides sidewall wall that refractory brick and blue or green ceramic tile are built by laying bricks or stones, on arch form top, be provided with the air distribution coal inlet hole of holding concurrently, on the arch form top, also be provided with and left and right sides sidewall wall, hole on the tempering road that furnace bottom tempering road communicates, the shortcoming of this type of furnace is, because furnace roof adopts refractory materials to build into the overall fixed form by laying bricks or stones, in different stepss such as coking and quenchings, because of difference variation is very big, furnace roof is affected by thermal expansion and contraction, cause the crack easily so that the top of collapsing, thereby influence the coke oven life-span greatly, secondly, owing to advance coal mainly by the furnace roof opening for feed, cause into coal inconvenience, time increases, and is difficult to raw material is tamped, and also influences the coke quality; The 3rd, this type of furnace heat radiation is slow, and the quenching cycle is long, and the interior temperature of stove is higher when the discharging of the coke, and has increased labor strength.

The purpose of this utility model is to avoid above-mentioned deficiency, and providing a kind of is convenient charging and discharge of the coke, and is easy to compacting, can prevents flue dust to airborne release again, contaminate environment, and the pit kiln bell to be opened/closed that can not cause furnace roof to subside.

The utility model is achieved in that this pit kiln bell is constituted by a plurality of separable arch form tegillums, each tegillum connects with side wall of furnace employing activity, and each isolating arch form tegillum is served as reasons with the activity connection of sidewall of the furnace body and constituted greater than the track that body of heater length cooperates with scroll wheel at the scroll wheel of each arch form tegillum two ends installation and the length that is provided with in the body of heater two side.

Described separable arch form tegillum, each tegillum can also be provided with the lid pin of band connecting hole at the one end, lid on the pin connecting hole and fix with the sidewall of the furnace body rigidity and the connecting hole that has on the bell base of connecting hole matches, and pass through steel pin and constitute with the activity of sidewall of the furnace body and connect.

There is the tooth of adhering to each the arch tegillum inboard that constitutes bell described in the utility model, and is convenient to the fixing of refractory materials, also has louvre covering.

The utility model has the advantages that: charging with discharge of the coke comparatively convenient; Shortened coking time; Be convenient to raw material is tamped; Alleviated pollution to environment; Avoided fully because the furnace roof that causes that expands with heat and contract with cold subsides.

Embodiment 1, the pit kiln bell that present embodiment is described is constituted by a plurality of arcual tegillums 5, each tegillum and sidewall of the furnace body, 2, the employing activity connects, when bell is closed, each isolating tegillum is combined into a complete bell, thelid pin 12 of twoband connecting holes 9 is arranged at tegillum 5 bottoms, connectinghole 9 on thelid pin 12 of tegillum 5 and match with the connectinghole 16 sidewall of the furnace body internal fixing and on thetegillum base 8 that the isometric channel-section steel 7 of sidewall of the furnace body is connected, and constitute each tegillum bysteel pin 15 and connect with the activity of sidewall of the furnace body, be provided with in the inboard of each tegillum and adhere totooth 13, increasing the stability thatrefractory materials 14 adheres to the bell inboard, and havelouvre 11 thereon, be provided withsuspension ring 6 at the arch tegillum by top, be convenient to the switching of tegillum, when bell need open, can use small winch tegillum to be sling one by one by set suspension ring inarch tegillum top 6, when needing closure, do inverse operation and get final product.

Embodiment 2: the described pit kiln bell of present embodiment is made up of some joint arch tegillums, at the tegillum two ends scroll wheel 17 is installed, be provided with thetrack 18 of length greater than body of heater length in the body of heater two side, the scroll wheel 17 at arch tegillum two ends andtrack 18 cooperate the flexible connection that constitutes bell and sidewall of the furnace body, and bell can respectively save the arch tegillum by push-and-pull and carry out opening and closing.

Arch tegillum described in the utility model can directly be cast or be welded.
