Description

A kind of strong limekiln is laid bricks

Technical field

The utility model relates to a kind of brick constructions more particularly to a kind of strong limekiln to lay bricks.

Background technique

Limekiln is a kind of MAERZ lime kiln that lime stone high-temperature calcination is generated to industrial quick lime.Two kiln thoraxes in limekiln Between by be arranged in middle part circular passage be connected to.Annular channel structure is as shown in Figure 1, by channel roof 1, interior wall 2 and exterior wall 3 Composition.Channel roof 1 is poured and is formed by top steel plate, heavy heat insulating casting material and lightweight heat-proof castable, is equipped in castable Anchor studs, for the self weight of heavy heat insulating casting material and lightweight heat-proof castable to be passed to top steel plate.Since castable is solidifying Gu when have obvious volume contraction, therefore before pouring, need to be arranged between lightweight heat-proof castable and top steel plate it is certain between Gap is closely knit with mineral wool filling after the completion of pouring.

In production run, temperature is up to 900 DEG C at circular passage, and pressure reaches 20kP in kiln, is that upper work is equipped in limekiln Condition environment is most severe, one of is easiest to the place for structure destruction occur, but corresponding interior wall is laid bricks in high-temperature flue gas at mineral wool Under huge horizontal pressure force, it is easy loose or dislocation since the mineral wool of behind can not provide enough horizontal supporting forces, it is this Partial structurtes, which are destroyed, to spread to surrounding rapidly, eventually lead to the destruction of entire kiln thorax brick construction, influence the limekiln operation longevity Life.

Utility model content

Problem to be solved in the utility model is, in view of the problems of the existing technology, providing a kind of can improve lime Kiln circular passage heat structure intensity, heated be pressurized that effectively prevent laying bricks loosen and the simple strong limekiln of structure is laid bricks.

In order to solve the above technical problems, the utility model proposes technical solution are as follows:

A kind of strong limekiln is laid bricks, including both ends of the surface, two sides and two junction, the faying face laid bricks in from Incline upwardly in kiln to relative level on the direction outside kiln.

As a further improvement of the above technical scheme:

Each faying face is parallel to each other.

In the faying face laid bricks, top surface is equipped with raised line and/or bottom surface is equipped with groove, and the raised line and groove are equal Vertical with side, two neighbouring described lay bricks mutually are locked by raised line with the cooperation of groove.

Described to lay bricks comprising dome brick, bottom brick and middle part brick, the bottom surface of the dome brick is equipped with groove；The top surface of the bottom brick It is equipped with raised line；The top surface of the middle part brick is equipped with raised line and bottom surface is equipped with groove.

The dome brick and bottom brick are fixed as one or the middle part brick is fixed between dome brick and bottom brick.

Compared with the prior art, the advantages of the utility model are:

The strong limekiln of the utility model is laid bricks, including both ends of the surface, two sides and two junction, the knot laid bricks Incline in facing upward out of kiln to relative level on the direction outside kiln in conjunction face.By masonry of laying bricks kiln body during the work time, by When the pressure F of horizontal direction from inside to outside, horizontal pressure force F can be decomposed into power F1 straight down and be tilted towards along faying face On power F2.It is even closer that power F1 straight down connects neighbouring laying bricks, and increases bonding strength, inclines along faying face Power F2 obliquely can be offset by frictional force with suffered Gravitational sliding component itself is laid bricks, and connected compared to straight brick body When brick body between can only be guaranteed for bonding strength with the bonding force of adhesive between frictional force and brick body, faying face is incline structure The stress performance laid bricks it is obviously more preferable, even behind be laying bricks for mineral wool region will not be easy to loosen and fall off, respectively Bonding strength between laying bricks is higher, and the kiln body wall surface for masonry of laying bricks is also stronger.

Specific embodiment

For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to practical new herein Type, which is done, more comprehensively, meticulously to be described, but the protection scope of the utility model is not limited to following specific embodiments.

Embodiment:

The strong limekiln of the present embodiment is laid bricks, including both ends of the surface, two sides and two junction, lay bricks 4 faying face Incline in facing upward out of kiln to relative level on the direction outside kiln.By the kiln body wall surface for 4 masonry of laying bricks as shown in Fig. 2, by from When the pressure F of horizontal direction from inside to outside, lay bricks 4 stress condition as shown in figure 3, horizontal pressure force F can be decomposed into vertically to Under power F1 and the power F2 that is tilted upward along faying face.Power F1 straight down keeps neighbouring 4 connections of laying bricks even closer, Bonding strength is increased, the power F2 tilted upward along faying face can be by frictional force and 4 itself suffered Gravitational sliding point of laying bricks Power is offset.It can only guarantee to connect with the bonding force of adhesive between frictional force and brick body between brick body in connection compared to straight brick body Connect for intensity, faying face be incline structure lay bricks 4 stress performance it is obviously more preferable；Even it is in the block in mineral wool region Brick 4, due to adjacent 4 tightness degrees height of laying bricks, the probability for occurring individually loosening and falling off is greatly reduced, 4 masonry of laying bricks Kiln body wall surface it is also stronger.

In the present embodiment, lay bricks 4 each faying face it is parallel to each other, the anti-thrust direction that parallel faying face provides is more Unanimously, resist and push away that ability is stronger, and parallel structure is easier to process.

In the present embodiment, as shown in Fig. 2, fig. 4 to fig. 6,4 are laid bricks comprising dome brick 43, bottom brick 44 and middle part brick 45, dome brick 43 Bottom surface be equipped with groove 42, top surface is vertical with both ends of the surface；The top surface of bottom brick 44 is equipped with raised line 41, and bottom surface and both ends of the surface Vertically；The top surface of middle part brick 45 is equipped with raised line 41 and bottom surface is equipped with groove 42.Raised line 41 and groove 42 are vertical with side.

When building to limekiln, it first is laid with the straight bottom brick 44 in bottom surface in bottom surface, then be superimposed above bottom brick 44 Middle part brick 45, after the completion of the superposition of middle part brick 45, at middle part, the top of brick 45 is laid with the straight dome brick 43 in top surface；It is each neighbouring Lay bricks and mutually locked by raised line 41 with the cooperation of groove 42 between 4, when by being internally pointed to external horizontal direction from kiln body Pressure when, anti-pressure ability can be further strengthened between 4 by this locking mechanism by laying bricks, this locking mechanism make to lay bricks 4 it Between bonding strength it is higher, local pressure can be dispersed to entire wall surface, improve the anti-pressure ability of limekiln brick face entirety.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment.For those skilled in the art, obtained by under the premise of not departing from the technical concept of the utility model Modifications and variations also should be regarded as the protection scope of the utility model.
