Abstract

The utility model relates to the technical field of coking equipment, in particular to a U-shaped hollow insulated coke oven door lining brick, comprising a U-shaped brick body and brick ditches. The U-shaped brick body is composed of an arch groove inner brick body and a convex arch inner brick body matching with the arch groove inner brick body. The groove matches with the convex arch. The inner brick body is a hollow brick body. The brick ditches are installed outside the convex arch inner brick body. The combining part of the outer brick body and the inner brick body is provided with an inner lockhole passage. The U-shaped brick body is a high alumina cordierite lining brick with middle long holes with the height of 400 to 600 mm. The external surface of the U-shaped brick body is provided with a glaze layer with the thickness of 1 to 3 m. A heat-resistant cast-iron bar which is thick in the middle and thin at both ends is installed under a raised head of the inner brick body. An oven door metal trough is fixedly connected with the oven door lining brick via an internal lock stay bolt passing through the oven door metal trough. The U-shaped hollow insulated coke oven door lining brick has the following advantages that: the inner brick body is a hollow brick body, thereby obviously reducing the heat loss of the coke oven; the groove matches with the convex arch, thereby improving the intensity of the whole oven door lining brick. The external surface of the oven body is difficult to be hung with coke tar and is easy to be cleaned, thereby reducing the labor intensity.

Description

Shape of a hoof hollow insulation fire door lining brick of coke oven

Technical field

The utility model relates to the coking equipment technical field, particularly a kind of shape of a hoof hollow insulation fire door lining brick of coke oven.

Background technology

Coke oven door is the important component part of coke oven, and present employed coke oven door is high alumina trichroite lining brick mostly, and minority is used the high-strength float bead lining brick, and the brick type is thinner, and horizontal joint is many, tar easy to hang, cleaning difficulty.The brick type divides levorotation right type, and the right type of levorotation is staggered when building by laying bricks or stones.This fire door lining brick anti-vibrating and impact ability, fire door is low work-ing life, and gross weight is big, and effect of heat insulation not what is enough desirable, and environment distributes a large amount of heats towards periphery, is referred to as tropical island effect.Utility model patent ZL200620091980.1 " fire door lining brick of coke oven of the diffusing heat insulation material of shape of rest shape of a hoof hollow perfusion " is made up of shape of a hoof brick body, outside glaze layer, the diffusing heat insulation material elongated hole of shape post pouring body and brick ditch.This fire door lining brick of coke oven has many advantages, but also still exists some can room for improvement.

Summary of the invention

The purpose of this utility model is to provide a kind of good heat insulating, good integrity, shape of a hoof hollow in light weight, that the life-span is long to be incubated fire door lining brick of coke oven.

The purpose of this utility model realizes by following technical proposals:

Shape of a hoof hollow insulation fire door lining brick of coke oven of the present utility model, comprise shape of a hoof brick body, Zhuan Gou, it is characterized in that described shape of a hoof brick body by the outer brick body of arc groove and therewith groove shape outward in the convex that is complementary of brick body the brick body formed, the convex arc of brick body is complementary in the groove of the outer brick body of arc groove and the convex, the brick body is the Hollow brick body in this convex, and described brick ditch is located at the external side of brick in this convex.Shape of a hoof brick body is suspended on the furnace door brick groove by the brick ditch.

The junction of brick body is provided with the internal lock duct in outer frog brick body of described arc and the convex.

Described shape of a hoof brick body is the high alumina trichroite lining brick of elongated hole in the middle of having of high 400-600mm.

The outer surface of described shape of a hoof brick body hangs with the glaze layer that a layer thickness is 1-3mm.

The plush copper of brick body has the thin heat resisting iron rod in thick two, a centre in the described convex, thin two is imbedded in the described brick body internal lock duct, and this heat resisting iron rod is fixedly connected fire door metal trough and fire door lining brick by an internal lock thru-bolt that passes the fire door metal trough.

Shape of a hoof hollow insulation fire door lining brick of coke oven of the present utility model has following advantage:

1, because the interior brick body of convex is the Hollow brick body, alleviated the weight of brick body, simultaneously middle elongated hole becomes fabulous thermofin, has reduced the loss of coke oven heat significantly, and shape of a hoof brick body head temperature raises, and therefore can improve the quality of coke; Simultaneously, the temperature of fire door ironware reduces 50-100 ℃, and both energy-conserving and environment-protective can prolong life-span of fire door again.

2, since shape of a hoof brick body by the outer brick body of arc groove and therewith in the convex that is complementary of the outer brick body of groove shape the brick body formed, the convex arc of brick body is complementary in the groove of the outer brick body of arc groove and the convex, interlock mutually, it is well whole to make whole fire door lining brick become sealing property, has improved the intensity of whole fire door lining brick.

3, owing to fire door metal trough and fire door lining brick are fixedly connected with the internal lock thru-bolt, can in time adjust contact tightness degree between fire door metal trough and the fire door lining brick with nut, guarantee that whole fire door is well integral body of sealing property all the time.

4, because the outer surface of shape of a hoof brick body hangs with the glaze layer that a layer thickness is 1-3mm, the outside surface of brick body tar not easy to hang, cleaning is just not difficult yet, thereby has reduced labor intensity of operating personnel.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Embodiment

Given embodiment further specifies embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, according to shape of a hoof hollow insulation fire door lining brick of coke oven of the present utility model, comprise shape of a hoof brick body 1, brick ditch 4, it is characterized in that described shape of a hoof brick body 1 by the outer brick body 5 of arc groove and therewith arc groove outward in the convex that is complementary of brick body 5 brick body 6 formed, the groove 7 of the outer brick body 5 of arc groove is complementary with the convex arc 8 of the interior brick body 6 of convex, brick body 6 is the Hollow brick body in this convex, and described brick ditch 4 is located at brick body 6 outsides in this convex.Shape of a hoof brick body 1 is suspended on the furnace door brick groove 10 by brick ditch 4.

The junction of brick body 6 is provided with internal lock duct 9 in outer brick body 5 of described arc groove and the convex.
