CN2261430Y - Combined coke oven cover with oxygen supplying hole - Google Patents

Abstract

The utility model belongs to the technical field of coking equipment, particularly relates to a coke oven cover, which is mainly composed of longitudinal beams, firebricks, a fixed screw bolt, refractory cement, etc. The utility model is characterized in that lower ends of two L-shaped longitudinal beams are clamped in H-shaped grooves of a plurality of oxygen transportation firebricks, oxygen transportation holes are arranged on the oxygen transportation firebricks, and a screw bolt with a double head is arranged between the two longitudinal beams. When the utility model is used, a matched crane is used for grouping oven covers which are assembled well in advance, the oven covers move between two ovens, and seams among each group are sealed by using yellow mud. Compared with the prior art, the utility model has the advantages that operation is flexible and convenient, coke ingress and egress are convenient, seal performance is good, outer dust invasion does not exist, coke maturation is consistent, quality is good, and the utility model is suitable for various oven shapes.

Description

Have the built-up type lid for coke oven of curing by oxygen therapy the hole

The utility model belongs to the coking equipment technical field, is specifically related to a kind of lid for coke oven.

The bell that binds of existing pit kiln generally adopts TJ75 type, 89I type, 89II, these several pit kiln of 9L type, adopting arch form furnace roof and body of heater as the TJ75 coke oven is inseparable one, be unfavorable for coalingging compacting with discharge of the coke, consume man-hour big, the production cycle is long, yield poorly; Binding of 89III type is made up of the some arch form metal tegillums that flexibly connect, owing to influenced by the coking pyritous, easy deformation can not cooperate each other well, sealing effectiveness is poor: the binding to be worn on the T sections beam by some quarls of 91 types formed, the slit of refractory brick is that a large amount of slags are poured on the burnt body when the discharging of the coke, and enter in the coke by the slag sealing, outer ash is increased, grade reduces, and economic benefit is impaired, is difficult for continuing to promote the use of.

The utility model overcomes the weak point of prior art existence and provides a kind of oxygen therapy effective, and coking time is short, and conveniently moving is installed, sealing good heat preservation performance, a kind of built-up type lid for coke oven of free from dust.

The utility model is to realize like this, have the built-up type lid for coke oven of curing by oxygen therapy the hole, comprise longeron, refractory brick, holding bolt, the lower end that it is characterized in that two L type longerons is stuck in the I-shaped groove of some blocks of oxygen therapy refractory brick, the oxygen therapy hole is located on the oxygen therapy refractory brick, between two longerons threaded stud is housed, L type longeron adopts cast iron materials to make.Oxygen therapy of the present utility model hole is located on the bell burns fully, can burn the waste residue at coke top, has solved the burnt phenomenon of body of heater oxygen therapyization.

Description of drawings:

Fig. 1 has the built-up type lid for coke oven structural representation of curing by oxygen therapy the hole

Label declaration:

1, longeron 2, oxygen therapy refractory brick 3, holding bolt

With reference to the accompanying drawings embodiment is further described, have oxygen therapy hole built-up type lid for coke oven by the L shaped longeron of cylinder iron making 1, oxygen therapy refractory brick 2, holding bolt 3, the lower end of two L shaped longerons 1 is stuck in the I-shaped groove of some blocks of oxygen therapy refractory brick 2, oxygen therapy hole 4 is located on the oxygen therapy refractory brick 2, between two longerons 1 threaded stud 3 is housed, during assembling, after refractory brick 2 arranged, the lower end of longeron 1 is snapped in the I-shaped groove of refractory brick 2, then with the fastening top, furnace wall that places of threaded stud, according to the coke oven size, some groups of bells can be formed a complete bell, cover refractory cements above every group, seal with yellow mud between two groups of refractory brick.When the discharging of the coke, the bell grouping that combines is moved between two stoves, also can install and remove as required, be convenient to discharge of the coke with supporting lifting machine

The utility model compared with prior art has saves the material that binds, and flexible and convenient operation is convenient to charging Discharge of the coke, good seal performance, coking time is short, does not have outer ash and invades environmental contamination reduction, furnace temperature height, coke Ripe consistent. The advantages such as quality is good are applicable to the various type of furnaces, are convenient to extensive popularization.

Claims (2)

1, a kind of built-up type lid for coke oven of curing by oxygen therapy the hole that has, comprise longeron, oxygen therapy refractory brick, holding bolt is characterized in that the lower end of two L shaped longerons 1 is stuck in the I-shaped groove of some blocks of oxygen therapy refractory brick 2, oxygen therapy hole 4 is located on the oxygen therapy refractory brick 2, between two longerons 1 threaded stud 3 is housed.

2, bell according to claim 1 is characterized in that described L type longeron 1 adopts cast iron materials to make.
