Abstract

The utility model discloses a kiln body refractory brick which comprises a brick body which is enclosed by two oppositely-arranged top surfaces, two lateral sides and two end faces. The two lateral sides are provided with clamp connection protrusions, the two end faces are provided with clamp connection grooves, and the clamp connection protrusions and the clamp connection grooves are arranged on the small horizontal plane to form a clamp connection ring. In a refractory layer built by the refractory bricks, friction between horizontal brick layers and vertical bricks is improved compared with smooth surface refractory bricks in the prior art. Thus, even if bricks are different in deformation due to expansion with heat and contraction with cold for a long time, the integral strength of the refractory layer is hardly affected due to the clamp connection protrusions and clamp connection grooves. Curve gaps can effectively insulate heat loss directly caused by thermal radiation in a kiln.

Description

Kiln body of heater refractory brick

Technical field

The utility model relates to a kind of kiln body of heater refractory brick, particularly relates to a kind of firebrick structure for kiln body of heater refractory layer.

Background technology

Kiln is the multi-field important Thermal Equipments such as metallurgy, chemical industry, building materials and light industry, is used for product and fires.By the heating by ignition of fuel, firing temperature can reach 1200～1300 ℃ usually in the kiln, for prevent heat energy in the kiln to external diffusion, the kiln furnace body inside is provided with flame retardant coating usually, flame retardant coating is comprised of the fibrous material such as cotton, felt and refractory brick.

By the flame retardant coating that forms the kiln body of heater of piling up of refractory brick, conventional refractory brick brick body is cuboid, makes up flame retardant coating with the mode of piling up building wall, fills the grey matter binding agent between the refractory brick.Kiln in use, furnace body temperature changes greatly, it is a repeatedly process of heating and cooling, because the single individual difference of refractory brick, its degree varies of expanding with heat and contract with cold, after therefore must using in a period of time, bulk deformation easily appears in flame retardant coating, flame retardant coating after the distortion is so that the slit between each monolithic refractory brick changes obviously, and some greatly can not fill the mortar joint of filling fully owing to the slit between the refractory brick becomes.Heat very easily passes through these slits to external diffusion in the kiln body of heater like this, causes energy loss, affects furnace heat efficiency.At kiln repeatedly behind the heating and cooling, the grey matter binding agent of filling between refractory brick also can cause and peel off, on the one hand so that between the refractory brick connection power weaken, affect the flame retardant coating bulk strength, on the other hand, the slit that reserves after the grey matter binding agent peels off also can be so that the loss of heat in the kiln.

The utility model content

The purpose of this utility model is to provide a kind of kiln body of heater refractory brick, and a little less than the frictional force, the problem of thermal loss is easily caused in the gap between the brick body between solution brick body.

For solving the problems of the technologies described above, the technical solution of the utility model is such, a kind of kiln body of heater refractory brick, comprise the brick body, described brick body is surrounded by two end faces that are oppositely arranged, two sides and two end faces, it is characterized in that: two sides are provided with the clamping projection, and two end faces are provided with the clamping groove, and described clamping projection is positioned at same level with the clamping groove and forms the clamping ring.

The effect that runs off in order to obtain stronger trap heat, described brick body is provided with at least two clamping rings.

The advantage of technical scheme provided by the utility model is, side and end face at the brick body arrange respectively clamping projection and clamping groove, when piling up refractory brick, side and the corresponding clamping of the end face of another piece refractory brick with a refractory brick, in seam, fill simultaneously the grey matter binding agent, the like.The flame retardant coating that uses the refractory brick of this structure to pile up, between horizontal brick layer and brick layer and vertical fragment of brick and the frictional force between the fragment of brick compared to existing technology in the refractory brick blocks of surface smoothing be improved, therefore after the impact that is subject to for a long time expanding with heat and contract with cold, even distortion is inconsistent between single fragment of brick, but since clamping projection and clamping groove be arranged so that the impact that the flame retardant coating overall construction intensity is subject to is less, tortuous connection slit can effectively intercept in the kiln and directly cause heat-energy losses by heat radiation.

The specific embodiment

The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.

See also Fig. 1 to Fig. 4, the kiln body of heater is formed through high-temperature firing by refractory material with refractory brick.Refractory brick brick body is surrounded by two end faces 1 that are oppositely arranged, two sides 2 and two end faces 3, wherein two sides 2 are provided with clamping projection 41, two end faces 3 are provided with clamping groove 42, the cross sectional shape of clamping projection 41 is corresponding with the cross sectional shape of clamping groove 42, forms clamping ring 4 so that the projection 41 of the clamping clamping between brick body and the brick body is positioned at same level with clamping groove 42.Clamping projection 41 can be selected semicircle, rectangle or triangle as required with the cross sectional shape of clamping groove 42.

When piling up refractory brick of the present utility model, see also Fig. 5, the side 2a of a refractory brick 51 is relative with the end face 3b of another piece refractory brick 52, and namely so that clamping projection 41a is corresponding with clamping groove 42b, the rest may be inferred can form flame retardant coating.Interosculating so that the frictional force between the refractory brick increases of clamping projection and clamping groove strengthened the flame retardant coating bulk strength, and the labyrinth gap that forms between brick body side surface and end face also can effectively stop heat with the quick loss of heat radiation or thermal convection current form.

Another embodiment of the present utility model as shown in Figure 6, the clamping ring 4 of refractory brick can be arranged to three, and the refractory brick of a plurality of clamping ring setting is after piling up the formation flame retardant coating, and the frictional force between brick and the brick is larger, so that flame retardant coating intensity is larger, non-deformability strengthens.
