The purpose of this utility model is at existing problem, provide a kind of differential of the arc type kiln top to people, promptly the kiln section width of calcining kiln is 2.5M～4.6M, and thermal property is better, have a narrow range of temperature, life-span is long, good product quality, output height, hear rate is low, kiln structure is simple, and cost is low, integrates the energy-efficient tunnel cave of the advantage of semicircular arch, basket handle arch vault tunnel cave and flat-top tunnel cave.
The utility model comprises calcining kiln and hothouse, it is characterized in that:
A, calcining kiln comprises reinforced concrete base, the kiln top, the kiln body, ventilating duct and wicket, differential of the arc type kiln top is by top board, heat-insulation chamber between masonry and top board and masonry is formed, the roasting band masonry of kiln body is by the brick layer of building of following refractory arch, middle thermal insulation layer and top employing standard brick or coal gangue sintering porous brick, the arch layer that protects that hollow brick is built by laying bricks or stones constitutes, the preheating zone of kiln body, the salband masonry is by brick layer and top employing standard brick or the coal gangue sintering porous brick built of following refractory arch, the arch layer that protects that hollow brick is built by laying bricks or stones constitutes, place the kiln body both sides on the reinforced concrete base to be respectively equipped with brick ventilating duct, kiln body entrance point is equipped with the twice wicket, is provided with one between the twice wicket and reserves the chamber;
B, top, the hothouse chamber of comprising, chamber body, ventilating duct and import and export door, the top, chamber comprises the heat exchanging chamber composition between ceiling, top panel and ceiling, top panel, place the body both sides, chamber on the reinforced concrete base to be respectively equipped with brick ventilating duct, body top, chamber is equipped with one and is taken out air-heater and be communicated with calcining kiln by taking out warm-air pipe.
The kiln section width of calcining kiln is 2.5M～4.6M, be provided with temperature tube in the calcining kiln, the front portion is the preheating zone in the calcining kiln, the middle part is the roasting band, the rear portion is a salband, have coal feeding hole on the kiln top of calcining kiln roasting band, kiln body entrance point, preheating zone, salband both sides are equipped with the sand tube that adds of logical inboard from top to bottom respectively.
The masonry both sides are cast with the reinforced concrete longeron and are cast with the equidistant reinforced concrete vertical beam of a row, and reinforced concrete vertical beam lower end is connected with the kiln reinforced concrete base, and the upper end adopts the banded column lacing wire to connect.
The ventilating duct top of calcining kiln is equipped with an airway plate, have the air port on the ventilating duct of both sides in the kiln body, the air port that feeds preheating zone, salband two side lower parts in the air port of preheating zone in the calcining kiln, the air port that feeds roasting band in the calcining kiln, the feeding calcining kiln is equipped with alternating temperature regulator, roasting regulator, temperature control regulator respectively, and strong air-cooler is equipped with in the calcining kiln outlet.。
The ventilating duct top of hothouse is equipped with airway plate, it is middle certainly to gradually little air port, both sides to have a row in the kiln body on the ventilating duct of both sides, moisture-eliminating blower is equipped with at hothouse entrance point top, and hothouse entrance point and both sides, kiln body stage casing are equipped with the sand tube that adds of logical inboard from top to bottom respectively.
During use, when kiln car to be baked bricks being housed entering the kiln body on differential of the arc type kiln top, the first road wicket rises automatically, kiln car enters by the import hauling machine and reserves the chamber, after the first road wicket fell automatically, the second road wicket rose automatically, preset to reserve indoor kiln car and automatically kiln car is ejected by kiln car pusher and reserve the chamber and enter differential of the arc top kiln body, kiln car pusher automatically resets, and the second road wicket falls automatically.Kiln car enters and enters the preheating zone behind the kiln body and enter the roasting band again, because strong air-cooler is equipped with in the calcining kiln outlet, cold wind is sent into by brick air channel, body both sides, chamber, and brick body waste heat is blown into the roasting band when before kiln car continues, being advanced into salband, both, replenished oxygen to the roasting band again with UTILIZATION OF VESIDUAL HEAT IN.The high-temperature flue gas of roasting band burning advances backward, reached to after the adobe of coming in carry out preheating, after-heat enters hothouse by taking out air-heater.Because of not being sucks from atmosphere by wind circulation nature separately, but machinery is supplied with by force, thereby make the interior firing temperature of kiln even, firing period shortens, and can avoid the black core brick that occurs because of kiln temperature is inhomogeneous, energy-conservation, efficient, the advantage of burning till fast of having guaranteed therefore that this tunnel cave has.Because of the ventilating duct top of hothouse both sides is equipped with airway plate, it is middle certainly to gradually little air port, both sides that ventilating duct has a row, thereby change air supply mode into the side air-supply by the top air-supply of generally adopting, moisture-eliminating blower is equipped with at hothouse entrance point top, because hot gas is sent under two inboards, chamber,, avoided because of moisture regain causes the collapse generation of phenomenon of base substrate by the blower fan humidity discharging from the top, firing chamber, the body drying effect obviously improves.
Effect of the present utility model
1, the utility model has adopted differential of the arc type kiln top, and promptly calcining kiln internal diameter width is 2.5M ~ 4.6M, and the twice wicket is equipped with in the import of kiln body, be provided with one between the twice wicket and reserve the chamber, calcining kiln, hothouse all have brick ventilating duct simultaneously, and strong air-cooler is equipped with at calcining kiln port of export top again, moisture-eliminating blower is equipped with at hothouse entrance point top, hothouse port of export top is equipped with and is taken out air-heater, thereby thermal property is better, has a narrow range of temperature, life-span is long, good product quality, the output height, hear rate is low.
2, the utility model kiln structure is simple, and cost is low, is beneficial to popularization.
