It is low that technical problem to be solved in the utility model is to provide a kind of energy consumption, can reach the emerging pottery binary of the mud kiln of energy-conservation object.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The emerging pottery binary of a kind of mud kiln, comprises switch board and two kilns that are set up in parallel, and on two kilns, all offers scavenge port, and two scavenge ports connect by warm-air pipe; On each kiln, also all offer air exchange mouth, on air exchange mouth, be equipped with blower fan, described blower fan is connected with the output of switch board respectively; In each kiln, be equipped with heater and thermocouple, described heater is connected with the output of switch board respectively, and described thermocouple is connected with the input of switch board through transmitter respectively.The emerging pottery binary of mud kiln in this programme, a kiln is in cooling, cooling stage (hereinafter referred to as high temperature kiln), one in hydrofuge, dry stage (hereinafter referred to as low temperature kiln), utilize the effect of blower fan, make to form negative pressure in low temperature kiln, the high-temperature gas in high temperature kiln is introduced in low temperature kiln, green compact are heated, reduce heater power consumption, thereby reach the object of electricity saving and energy saving.In addition, the unlatching of blower fan or close, according to thermocouple, the testing result of temperature in kiln to be decided, for example, the maximum temperature of firing of setting the emerging greenwave body of mud in switch board is 1120 DEG C, at this temperature, continue to fire 0.8 hour, when receiving the temperature value signal that thermocouple sends, switch board (referring to high temperature kiln at this) arrives 1120 DEG C time, start timing, timing reached after 0.8 hour, close heater, stop kiln heating, start blower fan simultaneously, high-temperature gas in high temperature kiln is introduced in low temperature kiln, instead of as existing monomer kiln, open exhaust outlet, high-temperature gas is directly discharged, make high-temperature gas can be again used in the hydrofuge of the emerging greenwave body of mud in low temperature kiln, dry, and the hydrofuge temperature of the emerging greenwave body of mud is generally 100 DEG C of left and right, and need to slowly reach this temperature, dry time of hydrofuge is also longer, slow cooling in high temperature kiln, the high-temperature gas of discharging can meet the demand of low temperature kiln furnace heat completely.
According to hydrofuge, the drying property of the cooling characteristic of the emerging pottery of mud after having fired and the emerging greenwave body of mud, described scavenge port is preferably all opened in the bottom of kiln.
In order accurately to control the variation of temperature in kiln, further improve the rate of burning till and the fine work rate of the emerging greenwave body of mud, thermocouple in each kiln is preferably two, all be connected with the input of switch board by described transmitter, one of them thermocouple is located at scavenge port place, and another thermocouple is located at the bottom of kiln.
The kiln wall of described kiln preferably includes internal layer high temperature foam brick, intermediate layer warming plate and layer structure wall brick.
For making can be compared with uniform decrease in temperature in high temperature kiln, in low temperature kiln, can more evenly heat up, further to improve the rate of burning till and the fine work rate of the emerging greenwave body of mud, described warm-air pipe stretches into length in kiln and is at most the half of cavity length in kiln.
Described kiln is shuttle kiln.
Compared with prior art, the utility model is according to the emerging pottery firing process of mud feature, each section of sintering process carried out to energy level coupling: such as at high-temperature calcination stage (more than 1000 DEG C), it is the opportunity of the emerging pottery generation of mud transmutation, in this time period, can start the deep low gear of blower fan, high-temperature gas in high temperature kiln is flowed, strengthen the reducing atmosphere in high temperature kiln, to improve the transmutation rate of the emerging pottery of mud, and high-temperature gas is incorporated in low temperature kiln, because low temperature kiln need to heat slowly, at this moment high-temperature gas can meet the caloric requirement of low temperature kiln, and after the emerging pottery of mud in high temperature kiln fired, enter temperature-fall period, and the high-temperature gas of discharge increases, and the heat demand in low temperature kiln also increases, and both energy levels just mate, the energy level coupling of two kilns can arrange in switch board, makes the state of kiln atmosphere, air temperature and current precisely controlled, to improve the rate of burning till and fine work rate.And switch board operation be simple numeric ratio and control the rotating speed of blower fan, reach the target of calcination parameter control.
