Description
Technical field
The utility model belongs to the technical field of chain grate machine equipment, particularly a kind of refractory material masonry construction of chain grate machine preheating section.
Background technology
Along with the fast development that China's chain grate machine-rotary kiln pelletizing process is produced acid pellet, this technology progressively receives the extensive approval of industry.The normal operational relation of chain grate machine, rotary kiln, central cooler three big main frames is to the operating rate of whole production line, and the factor that can influence the normal operation of three big main frames is a lot, wherein refractory material rationally be used for the most important thing, receive generally attention.Chain grate machine-rotary kiln device is many, and each equipment working condition differs greatly, and the different parts refractory lining will bear the chemical erosion, rapid heat cycle effect of the washing away of different material, eutectic etc. respectively, and complex structure, construction and baking difficulty.As everyone knows: select the building method of rational refractory material and science not only can farthest protect the normally operation under the condition of high temperature of three big main frame steel construction pieces; And can also play energy saving purposes, thereby reduce the operation cost of manufacturer.
Chain grate machine preheating section can be divided into preheating I section and preheating II section generally speaking.Chain grate machine preheating section refractory material is because consider should high temperature resistant heat insulation again effect, and making composite construction generally speaking is that working lining adopts the heavy pours; Thermal insulation layer adopts lightening casting material, and these two kinds of pours form through the anchored brick one-piece casting.This structure has following shortcoming: 1) under the condition of high temperature; Because temperature difference causes the expansion amplitude of heavy pours and lightening casting material inconsistent; Will between two-layer pours, form shearing force like this; This shearing force finally can be delivered on the anchored brick, changes the maximum shear stress that can bear and will destroy anchored brick when this shearing force reaches anchoring, make two-layer pours from the junction tomography and the side wall bulge takes place or problem such as come off; 2) the work progress difficulty is big, because two-layer pours needs the lightening casting material of first construction heat-insulating layer, treats the lightening casting material outer heavy pours of constructing again after fixed.Owing to need anchored brick to connect, when construction internal layer lightening casting material, construction formwork must be dodged out anchored brick like this between the two-layer pours, and, also need the branch plurality of sections carry out pouring construction on the vertical direction, so more increased difficulty of construction; 3) internal layer pours moisture can't effectively be got rid of; Will reduce the lightening casting material function of use like this; Simultaneously, can be varied to steam when this part moisture runs into high temperature, this part steam has a thrust side wall may produce problems such as bulge perhaps comes off to outer heavy pours.
Summary of the invention
The purpose of the utility model provides a kind of high life, is prone to the refractory material masonry construction of a kind of chain grate machine preheating section of construction and easy baking.
The purpose of the utility model realizes through following technical proposals:
The refractory material masonry construction of the utility model chain grate machine preheating section; It is characterized in that by chain grate pusher side wall steel plate; Through the seccotine water layer calcium silicate board with microporous that is fixedly connected of chain grate pusher side wall steel plate therewith; Spread upon the water-repellent paint layer on this calcium silicate board with microporous, abut against the heavy cast bed of material on this water-repellent paint layer, evenly be embedded in one group of anchored brick in this heavy cast bed of material; One group of being connected of one group of anchored brick is hung brick spare and is formed therewith respectively; Described one group of extension brick spare all is embedded in the tissue of said calcium silicate board with microporous, and described calcium silicate board with microporous is provided with one group of anchored brick termination spliced eye, and described extension brick spare plugs with described anchored brick in this anchored brick termination spliced eye.
The utility model has the advantages that:
1) the utility model is because the lightening casting material intensity that calcium silicate board with microporous hardens is much lower; Like this when high-temperature condition during down when outer heavy pours drive anchored brick displacement the internal layer calcium silicate board with microporous can not stop the displacement of anchored brick; Can not produce shearing force between heavy pours and the calcium silicate board with microporous like this, can not destroy anchored brick anchored brick;
2) the utility model is because calcium silicate board with microporous intensity is lower, and it is simple, easy to dig anchored brick termination spliced eye during construction;
3) the utility model is because the calcium silicate board with microporous that is in internal layer contains moisture hardly, even the high temperature internal layer can not produce destructive steam yet, only need just can to outer field heavy pours formulation baking system during baker like this.And be provided with the water-repellent paint layer between the calcium silicate board with microporous and the heavy cast bed of material, can prevent effectively that heavy pours moisture from entering in the calcium silicate board with microporous, moisture can be along the final body of wall of discharging of diffusion on the calcium silicate board with microporous water-repellent paint course when baker, and baker is simple, quick.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The specific embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1; The refractory material masonry construction of the chain grate machine preheating section of the utility model; It is characterized in that by chain grate pusher side wall steel plate 1,, spread upon the water-repellent paint layer 5 on the calcium silicate board with microporous through seccotine water layer 7 calcium silicate board with microporous 3 that is fixedly connected of chain grate pusher side wall steel plate 1 therewith; Abut against the heavy cast bed of material 6 on this water-repellent paint layer 5; Evenly be embedded in one group of anchored brick 4 in this heavy cast bed of material, a group of being connected in the termination of one group of anchored brick 4 is hung 2 compositions of brick spare therewith respectively, hangs brick spare 2 and all is embedded in the tissue of said calcium silicate board with microporous for described one group; Described calcium silicate board with microporous is provided with one group of anchored brick termination spliced eye, and described extension brick spare 2 plugs with described anchored brick 4 in this anchored brick termination spliced eye.
Above-mentioned calcium silicate board with microporous has substituted original lightening casting bed of material; Because the lightening casting bed of material intensity that calcium silicate board with microporous hardens is much lower; Under high-temperature condition, when the outer field heavy cast bed of material drove the anchored brick displacement, the calcium silicate board with microporous that is in internal layer can not stop the displacement of anchored brick like this; Make between heavy pours and the calcium silicate board with microporous and can not produce shearing force, also just avoid anchored brick to be sheared the possibility that power is destroyed anchored brick.
Calcium silicate board with microporous and heavy cast branch surface, bed of material convergence part are provided with the water-repellent paint layer.Can prevent effectively that heavy pours moisture from entering in the calcium silicate board with microporous, moisture can be along the final body of wall of discharging of diffusion on the calcium silicate board with microporous water-repellent paint course when baker, and baker is simple.
