Description
Technical field
The utility model relates to tunnel cave technical field, specifically a kind of tunnel cave furred ceiling.
Background technology
Tunnel cave is the Thermal Equipment that modern continous way is burnt till, be widely used in the baked for producing of pottery, brick and tile product, tunnel cave divides by the width of firing chamber roughly to be had: the large cross-section tunnel kiln of more than 4.5m, 2.5m-4.0m middle section tunnel cave, be less than the narrow-bore tunnel kiln of 2.5m, but narrow-bore tunnel kiln belongs to the backward kiln type be eliminated.
Tunnel cave is generally long linear tunnel, and its both sides are wall, and top is furred ceiling, and furred ceiling is provided with refractory masses, are fixed by anchoring piece or suspender, and furred ceiling mainly contains vault peace furred ceiling, and refractory material mainly adopts refractory brick or heat-preservation cotton.The shortcoming of vault tunnel cave is that in kiln, upper and lower temperature difference is comparatively large, overdoing below, deficient temperature above, and product percent of pass is lower, and is not suitable for the tunnel cave of middle section or big cross section; And refractory material adopts heat-preservation cotton, it just plays function of heat insulation, but easily agingly to become fragile, change frequent, cost is high, and the phenomenon of crackle, fracture easily appears in product, although employing refractory brick carries out, suspension is fixing also has related application, but in property quick for installation, connectivity robustness or defectiveness, kiln accident of collapsing odds is still larger.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of quick for installation, be connected firmly, the good tunnel cave furred ceiling of product quality.
The technical scheme that the utility model adopts is: provide a kind of tunnel cave furred ceiling, is arranged to build by laying bricks or stones to form by multiple refractory brick, is provided with suspension bracket, is provided with the suspension hook hanging refractory brick between described suspension bracket and refractory brick above described refractory brick; The top of described refractory brick two opposite side walls is equipped with the upper groove of end face and lateral opening, through hole is provided with between upper groove, described suspension hook upper end is connected with suspension bracket, and suspension hook lower end is inserted in through hole, and the bottom of described refractory brick two opposite side walls is respectively equipped with corresponding projection and low groove; Described multiple refractory brick arrangement refers to that refractory brick is bonded to each other, and the projection on refractory brick sidewall embeds in the low groove of another refractory brick.
After adopting above structure, the utility model tunnel cave furred ceiling uses refractory brick as flame retardant coating, hang fixing in through hole by suspension hook insertion refractory brick, flame is difficult to skewered to suspension hook, the top of refractory brick two opposite side walls is equipped with upper groove, not only alleviate the weight of refractory brick, also the operation of suspension hook is facilitated, installation becomes quick, refractory brick sidewall is fitted together to mutually by protruding and low groove, the furred ceiling of formation is made to connect closely, sturdy and durable, the wide above tunnel cave of 3.6 meters, section can be built by laying bricks or stones, adopt the furred ceiling of this structure, product quality is better, and save coal more than 15%, reduce production cost more than 30%.
As improvement, described tunnel cave furred ceiling is the micro-arch in middle part, and the height of the micro-arch in middle part and the wide ratio of kiln are 0.013 ~ 0.014.Compared with vault peace furred ceiling, the advantage of this kind of tunnel cave furred ceiling improves kiln scetion utilization, reduces the section temperature difference, be beneficial to baking operation.
As improvement, described suspension bracket is made up of I-steel and angle steel, and bottom is located at by described I-steel, and angle steel is located on I-steel, and suspension hook is stainless steel suspension hook, and this vibrational power flow makes suspension bracket steadiness strengthen, and kiln situation of collapsing not easily appears in kiln furred ceiling.
