Abstract
The invention relates to a hung ceiling of a tunnel kiln. The hung ceiling is constructed by arranging a plurality of refractory bricks, a hanging bracket is arranged above the refractory bricks, and hooks for hanging the refractory bricks are arranged between the hanging bracket and the refractory bricks. The upper portions of the two opposite sidewalls of each refractory brick are each provided with an upper groove with an open top surface and an open side face, a through hole is formed between the upper grooves of each refractory brick, the upper ends of the hooks are connected with the hanging bracket, the lower ends of the hooks are inserted into the through holes, and the lower portions of the two opposite sidewalls of each refractory brick are provided with a protrusion and a lower groove respectively and correspondingly. When the refractory bricks are arranged, the refractory bricks are attached to one another, and the protrusion on the corresponding sidewall of one refractory brick is embedded in the lower groove of another refractory brick. The hung ceiling of the tunnel kiln is rapid to install, firm in connection and good in product quality.
Description
Technical field
The present invention 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 by this invention is: provide a kind of quick for installation, be connected firmly, the good tunnel cave furred ceiling of product quality.
The technical solution adopted in the present invention 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, tunnel cave furred ceiling of the present invention 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.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Fig. 1 ~ Fig. 4, tunnel cave furred ceiling of the present invention, arranged to build by laying bricks or stones by multiple refractory brick 1 and form, suspension bracket is provided with above refractory brick 1, the suspension hook 4 hanging refractory brick 1 is provided with between suspension bracket and refractory brick 1, the top of refractory brick 1 two opposite side walls is equipped with the upper groove 1.2 of end face and lateral opening, through hole 1.1 is provided with between upper groove 1.2, namely bow and see in " work " font in refractory brick 1 top, each suspension hook 4 hooks one block of refractory brick 1, suspension hook 4 two ends all bend, suspension hook 4 upper end and suspension bracket are welded to connect, suspension hook 4 lower end is inserted in through hole 1.1, the bottom of refractory brick 1 two opposite side walls is respectively equipped with corresponding projection 1.3 and low groove 1.4, multiple refractory brick 1 arrangement refers to that refractory brick 1 is bonded to each other, projection 1.3 on refractory brick 1 sidewall embeds in the low groove 1.4 of another refractory brick 1.
