Burn till requirement for the flow velocity that can control haydite satisfies, the angle that forms between the bottom of said clinkering zone and its floor projection line is 5-15 °.
For the high energy of the sintering temperature that makes clinkering zone reaches 1300 ℃, the heater that is located at the clinkering zone top board is an elema heater.
In order to make haydite utilize self gravitation to flow, the angle that forms between the bottom of said dry zone and its floor projection line is 35-45 °.
In order to get rid of moisture content and the volatile component in the granule materials, the heater that is located at the dry zone bottom is a resistance wire heating carborundum heating board, the exhaust rod is installed above dry zone and heating tape the gas of generation is in time discharged.
In order to make haydite utilize self gravitation to flow, the angle between the bottom of said preheating zone and its floor projection line is 35-45 °.
The top and the heater on the bottom that are located at the preheating zone are resistance wire heating carborundum heating board.
The principle of the utility model: haydite is uniform circular granule good fluidity; Utilize the flowability of haydite self and the controllability of flow velocity to make it divide speed to flow, make a naughty grain material in flow process, accomplish sintering from dry zone, preheating zone, clinkering zone, salband segmentation; Haydite is circular granule, in sintering process, adds having a narrow range of temperature of thermosetting, is easy to soaking and grills thoroughly, and can implement to burn till fast.
Beneficial effect: compared with prior art, the advantage of the utility model is that kiln is a stationary, and heating space is little; Be easy to insulation, the firing temperature system is stable, and the firing temperature control accuracy is high; Heat utilization efficiency is high, and heat consumption is low, and power consumption is little; Automaticity is high, significantly reduces production costs effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement (as changing sectional dimension, mode of heating, angle of inclination etc.), these improve the protection domain that also should be regarded as the utility model.
As shown in Figure 1, a kind of haydite rapid firing kiln stove comprises body of heater; On body of heater, be provided with charging aperture 1 and discharging opening 2; The inner chamber of body of heater is divided into dry zone 3, preheating zone 4, clinkering zone 5 and salband 6 successively along the direction of charging aperture 1 to discharging opening 2, and dry zone 3 communicates with charging aperture 1, and discharging opening 2 communicates with salband 6; The bottom surface of body of heater inner chamber is domatic; Outside at dry zone 3, preheating zone 4 and clinkering zone 5 is equipped with heat-insulation layer 7, between preheating zone 4 and clinkering zone 5, is provided with the flashboard 8 of control haydite flow velocity, in dry zone 3 and preheating zone 4, is equipped with a plurality of exhausts rods 9; Be equipped with resistance wire heating carborundum heating board in the bottom of dry zone 3, the top and the bottom of preheating zone 4, be provided with elema heater 10 at the top of clinkering zone 5.
