Abstract
The utility model relates to a fire-barrier beam of industrial tunnel kiln, which consists of two stainless steel plates, wherein a block of refractory insulation cotton is clamped between the two stainless steel plates with bolts, the size of the refractory insulation cotton is matched with that of the stainless steel plate, and the two sides of the stainless steel plate are respectively and vertically connected to a regulation screw rod which is used for regulating the height of fire-barrier beam. The stainless steel plate of the utility model is subjected to creep deformation, namely dropping off stepwise, under high temperature condition, and is prevented from dropping off largely or completely, such that the smashing accident of conventional fire-barrier beam can be prevented; the insulation cotton cannot be expanded largely at high temperature, and the severe deformation which is caused by high temperature expansion can be prevented by applying the insulation cotton to the stainless steel plate; and the fire-barrier beam which is damaged and cannot be used can be replaced at any time, and the production cannot be influenced.
Description
Technical field
The utility model relates to a kind of industrial tunnel cave and keeps off fiery beam, belongs to the improvement of the retaining fire girder construction of using in the industrial production.
Background technology
In the sponge iron tunnel production technology, tunnel cave keeps off the design of fiery beam and normally does framework with reinforcing bar, high alumina fine powder, well as clay fines add the aggregate cast and form, learn according to production practices, there are the following problems in the design of the fiery beam of this retaining: 1. water material feeding owing to calcination for a long time, its quality becomes loose, and the time is long slightly, meeting expansion, cracking, fritter come off, the fiery effect of influence retaining.2. be shed to a certain degree when watering material feeding, can make outside its inner steel bar framework is exposed to calcination at high temperature for a long time, reinforcing bar melts, fracture, and the material feeding of watering of adhering on it loses impetus, can bulk come off, hinder car, find untimelyly, then can cause the major accident that pours in down a chimney.
Summary of the invention
The purpose of this utility model is to provide a kind of industrial tunnel cave to keep off fiery beam, and it is simple in structure, is easy to manufacture, even long-time calcination can guarantee that also keeping off fiery effect does not reduce, guarantees to produce and normally carries out.
The purpose of this utility model is achieved in that a kind of industrial tunnel cave keeps off fiery beam, this keeps off fiery beam and comprises two corrosion resistant plates, by the bolt clamping fire resistant heat preserving cotton is installed in the middle of two corrosion resistant plates, the size of heat-preservation cotton and the size of corrosion resistant plate are complementary, and the both sides of corrosion resistant plate vertically connect respectively to catch fire one adjusts the adjusting screw mandrel of retaining deck-molding lower position.
The utility model is made two corrosion resistant plates by the fiery beam size of its original retaining, makes an addition between two corrosion resistant plates with heat-preservation cotton again, and compacting, last, tighten with bolt; With the retaining fire of making " plate ", add to original retaining Huo Liang position, two ends are the up-down adjustment screw mandrel fixedly, is convenient to adjust the fiery beam of retaining height up and down, and the top is sealed with seat clay and heat-preservation cotton; " creep " takes place and promptly successively comes off under hot conditions in stainless steel, can bulk or integral body come off the accident of avoiding the fiery beam bulk of tradition retaining to fall to pounding jar; Bigger expansion can not take place in heat-preservation cotton under hot conditions, add among the corrosion resistant plate with heat-preservation cotton, can guarantee gross distortion not to take place because high temperature expands; Keep off fiery beam and damage in the time of to use, can change at any time, can not influence production.The utility model is simple in structure, is easy to manufacture, even long-time calcination can guarantee that also keeping off fiery effect does not reduce, guarantees to produce and normally carries out.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of industrial tunnel cave keeps off fiery beam, as shown in Figure 1, the two ends that keep off fiery beam are set up in above the kiln wall 4, this keeps off fiery beam and comprises two corrosion resistant plates 1, by the bolt clamping fire resistant heat preserving cotton 2 is installed in the middle of two corrosion resistant plates 1, the size of the size of heat-preservation cotton 2 and corrosion resistant plate 1 is complementary, and the both sides of corrosion resistant plate 1 vertically connect respectively to catch fire one adjusts the adjusting screw mandrel 3 of retaining deck-molding lower position.
Said fire resistant heat preserving cotton 2 is for to be made of alumina silicate heat-preservation cotton or ceramic fibre heat-preservation cotton, and the thickness of heat-preservation cotton 2 is 1-10cm.
Claims (2)
1. an industrial tunnel cave keeps off fiery beam, it is characterized in that: this keeps off fiery beam and comprises two corrosion resistant plates, by the bolt clamping fire resistant heat preserving cotton is installed in the middle of two corrosion resistant plates, the size of heat-preservation cotton and the size of corrosion resistant plate are complementary, and the both sides of corrosion resistant plate vertically connect respectively to catch fire one adjusts the adjusting screw mandrel of retaining deck-molding lower position.
2. industrial tunnel cave according to claim 1 keeps off fiery beam, it is characterized in that: said fire resistant heat preserving is cotton for to be made of alumina silicate heat-preservation cotton or ceramic fibre heat-preservation cotton, and the thickness of heat-preservation cotton is 1-10cm.
