Abstract
The utility model provides a refractory brick for vertical back burning boiler firepot groups, which is provided with a refractory brick body. The utility model is characterized in that a recessed cambered surface which is matched and inserted with the blank space between the firepot tube bank of the back burning boiler firepot is arranged between the inner side of the refractory brick body facing the firepot and the outer side, and the upper part and the lower part of the recessed cambered surface are symmetrical. The outer part of the intersecting of the cambered surface and the outer side is formed into a brick body which is clamped and bunted on the periphery side of the firepot tube bank and an outward convex clamping arris, the upper part and the lower part of which are symmetrical in directions, and the connecting position of the clamping arris and the cambered surface is formed into an adhesive feeding channel used for feeding the gap between the outer curved surface of the firepot tube bank and the combining position of the brick body. When the utility model is used, the brick body is clamped between the tube bank successively to form a combining firepot.
Description
The utility model relates to a kind of refractory brick, particularly a kind of vertical counter-burning boiler furnace spelling refractory brick.
The vertical counter-burning boiler is to use comparatively general a kind of middle-size and small-size heating and life use stove at present, its burner hearth generally adopts clay to ward off and makes the arch flame retardant coating, this flame retardant coating in use for some time, easily because of high temperature sintering and expand with heat and contract with cold and produce be full of cracks and come off, can't use and often need patching again to making.Another kind of burner hearth is to adopt the rigid structure that the mode of weld metal fireguard constitutes between the burner hearth comb, referring to Fig. 1, all be the bigger metal material of thermal deformation influence of catching a cold then in burner hearth comb and fireguard, be the rigidity Welding Structure in addition, therefore, Chang Yin expand with heat and contract with cold and produce distortion and stress concentrated, cause comb often to be in the varying stress state that support is repeatedly drawn, so the comb life-span is short and easily crack and cause leaking, in case leak then boiler can't use.Repair and replacement are extremely required great effort time-consuming.In addition, the heat insulation effect of welding burner hearth is relatively poor, and heat utilization efficiency is low.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and provide a kind of and need not to weld, be affected by thermal expansion and contraction little, comb is difficult for breaking because of distortion and leaks, and has higher service life, fire box temperature, lights the vertical counter-burning boiler furnace spelling refractory brick of effect and characteristics easy to maintenance.
The purpose of this utility model is to realize by following technical scheme:
The utility model is a refractory brick body, it is characterized in that: the refractory brick body towards between the inside portion of burner hearth and the outside portion be one and the burner hearth comb of back firing boiler burner hearth between neutral gear place kissing by insert piece together and the recessed cambered surface of symmetry up and down, cambered surface be formed with a card rib that fastens at burner hearth comb outer circumferential side with the intersection, outside portion along brick body above-below direction symmetry evagination, card rib and cambered surface junction formation one are used to clog the adhesive of burner hearth comb positive camber and brick body assembling part gap using and fill out sticking conduit.During use, the brick body blocked successively be put between comb, promptly form an assembled burner hearth.
Therefore remarkable result of the present utility model is:
1, owing to substituted former welding metal fireguard with refractory brick body that can the assembly group, the distortional stress that not only having eliminated expands with heat and contract with cold is produced pulls open bad to the support of burner hearth comb, improved the service life of comb, and, have and implement conveniently, the characteristics of being convenient to keep in repair can be keeped in repair when normal operation of boiler.
2, be to have the refractory brick body that fine resistant to elevated temperatures rare earth high aluminium material is made owing to what adopt, thus good heat endurance and intensity had, thereby, have very high service life, simultaneously, have better heat insulating ability and thermal radiation effect than the metal baffle burner hearth.Help saving energy and reduce the cost, and can reduce smoke density, the protection environment.
3, because what adopt is that assembly group inlay card mode is combined into burner hearth and burner hearth comb bag is blocked in it, not only be convenient to construction, and be beneficial to local replacing, especially comb is covered by the latent dress mode in the brick body, the direct combustion that can make comb avoid stove fire is baked and oxidation, so not yielding and damage.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing:
Fig. 1 is the structural representation of existing counter-burning type burner hearth;
Fig. 2 is a structural perspective of the present utility model;
Fig. 3 is that the A of Fig. 2 is to view;
Fig. 4 is that the B of Fig. 2 is to view;
Fig. 5 is result of use figure of the present utility model;
Be described in detail below in conjunction with 2 to 5 pairs of concrete structures of the present utility model of accompanying drawing:
The utility model is a refractory brick body, it is characterized in that: the refractory brick body towards between the inside portion 1 of burner hearth and the outside portion 6 be one and the burner hearth comb of back firing boiler burner hearth between neutral gear place kissing by insert piece together and the recessed cambered surface 2 of symmetry up and down, cambered surface 2 be formed with a card rib 4 that fastens at burner hearth comb outer circumferential side with 6 intersections, outside portion along brick body above-below direction symmetry evagination, card rib 4 and cambered surface 2 junctions form one and are used to fill out the adhesive of the sticking vertical positive camber of burner hearth comb and brick body assembling part gap using and fill out and glue conduit 3.Referring to Fig. 2 to Fig. 4
The vertical section of the refractory brick body that the rare earth high aluminium material is made is shaped as that the inside portion is 1 wide, outside portion 6 is narrow, and half bushing shirt for recessed cambered surface 2 between the transition position of interior outside portion launches shape.Referring to Fig. 2 and Fig. 3
The inside portion 1 that burner hearth is formed in the assembly of the refractory brick body of being made by the rare earth high aluminium material is to have a bib convex edge 11 that all sides in the burner hearth comb are vertically screened, cambered surface 2 be by an arc sections 21 and one and the tangent inclined plane part 22 of arc sections 21 constitute.Referring to Fig. 2 and Fig. 3
The height of the inside portion 1 of the refractory brick body that the rare earth high aluminium material is made is the 100-210 millimeter, the height of outside portion 6 is the 40-60 millimeter, and thickness is 60 to 180 millimeters, and length is the 90-200 millimeter, the radius of arc sections 21 is the 20-80 millimeter, and bib convex edge thickness is the 10-15 millimeter.
Using method of the present utility model as shown in Figure 5, brick body described in the utility model is inserted assembly along neutral gear between each adjacent comb successively from inside to outside from inside to outside, before inserting assembly, can between cambered surface 2 and card rib 4, be coated with and spread adhesive or the bonding filler of using by transition position, insert then to piece together and form a refractory burner hearth, as a certain damage, can be by anchor clamps or the hand of putting on heat resistant gloves with its taking-up and change.
And in the utility model to the qualification of brick body size, be consider brick body size specification should with the comb spacing, diameter and boiler size match and make after test.
