Specific embodiment

It is with reference to the accompanying drawing and specific real to make those skilled in the art more fully understand the technical solution of the utility model Mode is applied to be described in further detail the utility model.

Embodiment 1:

As shown in Figure 1, mullite system can be used the present embodiment provides a kind of internal wall brick for annular passage interior wall At.

Internal wall brick in the present embodiment includes brick ontology 1, and the upper surface of brick ontology 1 is provided with the groove along first direction 11；The raised line 12 along first direction is arranged in the lower surface of brick ontology 1, and raised line 12 is adapted with groove 11；Raised line 12 is in brick ontology 1 Lower surface orthographic projection of the orthographic projection with groove 11 in the lower surface of brick ontology 1 it is not be overlapped.

Wherein, first direction refers to the circumferential direction of the annular passage using the interior wall brick masonry.It should be noted that Upper and lower surfaces in the present embodiment are an opposite concepts, and when brick ontology 1 is horizontally arranged, face upward is brick sheet The upper surface of body 1, face directed downwardly are the lower surface of brick ontology 1.

In the present embodiment, the upper surface of brick ontology 1 is arranged in groove 11, and the lower surface of brick ontology 1 is arranged in raised line 12, Groove 11 is adapted with the shape of raised line 12, and orthographic projection of the groove 11 with raised line 12 in the lower surface of brick ontology 1 be not be overlapped, I.e. the two is located at the different location of annular passage radially.Meanwhile the distance between groove 11 and medial surface and raised line 12 The distance between lateral surface is identical, wherein medial surface and lateral surface refer to brick ontology 1 perpendicular to annular passage radial direction Two sides.Thus when using interior wall brick masonry annular passage interior wall provided in this embodiment, it can be by upper layer internal wall brick following table The raised line 12 in face is embedded in the groove 11 of lower layer's internal wall brick upper surface, that is, passes through the raised line 12 of upper layer internal wall brick and lower layer's internal wall brick Groove 11 formed occlusion structure, adjacent two layers internal wall brick is locked together.Specifically, in the present embodiment, brick ontology 1 Raised line 12 and groove 11 are located at the different location of annular passage radially, therefore in the annular passage interior wall built, phase The integrated structure position of adjacent two layers of internal wall brick is different, interlaced occlusion, to make the relatively reliable jail of the connection between internal wall brick Gu enhancing the structural strength of annular passage radially, it is made to better meet the characteristic of expanding with heat and contract with cold of resistance to material, extends coke dry quenching furnace Service life.Further, in the present embodiment, ring can be enhanced using the occlusion structure (raised line 12 and groove 11) being staggered The structural strength of shape air duct interior wall makes internal wall brick to can reduce the setting quantity of occlusion structure compared with the existing technology Structure is more simplified, convenient for the masonry of annular passage interior wall.

It is understood that the setting position of raised line 12 and groove 11 can mutually be exchanged, that is, will be convex in the present embodiment The upper surface of brick ontology 1 is arranged in item 12, and groove 11 is arranged in the lower surface of brick ontology 1, this equally can achieve practical Novel purpose.

Preferably, in the present embodiment, the section of the raised line 12 be it is semi-circular, radius is 15 to 20 millimeters.Wherein, it cuts Face refers to the cross section of brick ontology 1 radially in annular passage.In the present embodiment, compared with the existing technology in radius be 12 millimeters Calculon ditch brick tongue, the radius of raised line 12 is bigger in the present embodiment, by increasing the section radius of raised line 12, can increase phase Bite force between adjacent two layers of internal wall brick, enhances the structural stability of annular passage interior wall.Specifically, according to the radius of raised line 12 Size according to actual conditions such as dry coke quenching scale, internal wall brick sizes to be configured, herein with no restrictions.

It should be noted that the cross sectional shape of the raised line 12 in the present embodiment is not limited to half on normal meaning Circle can be the arcuate shapes such as semicircular or ellipse due to the limitation of manufacture craft.

Preferably, the minimum range at the edge of raised line 12 and groove 11 apart from brick ontology 1 is 30 millimeters.That is groove 11 and brick Ontology 1 perpendicular to the two sides of annular passage radial direction minimum range and raised line 12 and brick ontology 1 perpendicular to annular wind The minimum range of the two sides of road radial direction is 30 millimeters.Further, the two and brick ontology 1 are perpendicular to annular passage radial direction The minimum range of the two sides in direction should be between 30 to 50 millimeters, to guarantee both to join to the snap action of internal wall brick most It is good.

Embodiment 2:

As shown in Fig. 2, the present embodiment provides a kind of annular passage interior wall, including provided in embodiment 1 any one in Wall brick.

Preferably, annular passage interior wall further include: the chamotte of resistance to material being set between adjacent two pieces of internal wall bricks (does not show in figure Out).The chamotte of resistance to material is filled between adjacent two pieces of internal wall bricks in adjacent brick layer and same brick layer, internal wall brick is carried out Bonding, prevents occurring crack between internal wall brick, guarantees the stability of annular passage interior wall.

In the annular passage interior wall of the present embodiment, raised line 12 and groove 11 cooperate, and two layers adjacent of internal wall brick is locked It is buckled together.Specifically, the raised line 12 of upper layer internal wall brick lower surface is embedded in the groove 11 of lower layer's internal wall brick upper surface, that is, pass through The raised line 12 of upper layer internal wall brick and the groove 11 of lower layer's internal wall brick form occlusion structure, and adjacent two layers internal wall brick is latched in one It rises.And the raised line 12 and groove 11 of brick ontology 1 are located at the different location of annular passage radially, therefore in the annular built In air duct, the integrated structure position of adjacent two layers internal wall brick is different, interlaced occlusion, to make connection between internal wall brick more Adding robust, the structural strength of enhancing annular passage radially makes it meet the elastic characteristic of resistance to material expanded with heat and contract with cold well, The problems such as to avoid the bulge of annular passage interior wall, collapse, extend the service life of coke dry quenching furnace.

Embodiment 3:

The present embodiment provides a kind of coke dry quenching furnaces, including the annular passage interior wall provided in embodiment 2.

In the coke dry quenching furnace of the present embodiment, in the raised line and lower layer that the internal wall brick of annular passage interior wall passes through upper layer internal wall brick The groove of wall brick forms occlusion structure, and adjacent two layers internal wall brick is locked together.And the integrated structure of adjacent two layers internal wall brick Position is different, interlaced occlusion, so that the connection between internal wall brick is relatively reliable securely, the structure of annular passage radially is strong Degree is bigger, can meet the characteristic of expanding with heat and contract with cold of resistance to material well, therefore the coke dry quenching furnace service life is longer.

It is understood that embodiment of above is merely to illustrate that the principles of the present invention and uses exemplary Embodiment, however the utility model is not limited thereto.For those skilled in the art, this is not being departed from In the case where the spirit and essence of utility model, various changes and modifications can be made therein, these variations and modifications are also considered as this reality With novel protection scope.
