Description
Technical field
The present invention relates to the burning equipment of a kind of Nixing pottery, be specifically related to a kind of Nixing pottery binary kiln.
Background technology
The kiln firing Nixing pottery at present substantially uses shuttle kiln, has an advantage in that the structure letter of shuttle kiln
Single, cost of equipment is low, goes for the burning till of goods of different calcining system, it is also possible to according to goods
Requirement firing atmosphere is varied and controlled neatly.But traditional shuttle kiln mainly carries out technique by people
The control of parameter, owing to people is accurate not to the state recognizing of kiln atmosphere, air temperature and current, therefore,
The acquisition of pottery art fine work has the biggest occasionality, and calcining system is difficult to optimize, high-quality goods output capacity
Little, higher relative to high-quality product yield kiln, certainly will firing kiln number be increased.On the other hand,
Shuttle kiln production process belongs to batch production method, according to the ablating work procedure of Nixing pottery possess low temperature dehumidifying,
It is dried, the feature (temperature of calcining is up to 1120 DEG C) of high-temperature calcination, by green at room temperature loading of kiln,
Being gradually heating to firing temperature subsequently, Nixing pottery base substrate, after reduction treatment, the most gradually drops
Temperature is to lower temperature, and product could kiln discharge.Kiln constantly circulates in intensification temperature-fall period, temperature-fall period
In waste heat fail to be fully recycled, this certainly will increasing along with firing process energy consumption.Therefore
It is necessary that researching and developing a kind of efficient waste heat utilizes Nixing pottery calcining kiln to control the Novel kiln under technical controlling
Stove, reduces the heat consumption of unit product, improves the utilization rate of the energy, it is achieved high efficiency of energy utilizes and pollutant
The industrialization reduced discharging produces.
It addition, to improve high-quality product yield further, it is important to improve the temperature of firing process, gas
The intelligentized control method of atmosphere sintering curve, and realize remaining pick up the heat at temperature-fall period simultaneously.
Summary of the invention
It is low that the technical problem to be solved is to provide a kind of energy consumption, it is possible to reaches the mud of energy-conservation purpose
Emerging pottery binary kiln.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of Nixing pottery binary kiln, including switch board and two kilns being set up in parallel, on two kilns
All offering ventilation mouth, two ventilation mouths are connected by warm-air pipe；Each kiln is the most all offered free
Gas exchange mouth, is equipped with blower fan on air exchange mouth, and described blower fan is respectively with the outfan of switch board even
Connect；Be equipped with heater and thermocouple in each kiln, described heater respectively with the outfan of switch board
Connecting, described thermocouple is connected with the input of switch board respectively through transmitter.Nixing pottery in this programme
Binary kiln, a kiln is in cooling, cooling stage (hereinafter referred to as high temperature kiln), one be in dehumidifying,
In the stage (hereinafter referred to as low temperature kiln) being dried, utilize the effect of blower fan, in making low temperature kiln, form negative pressure,
High-temperature gas in high temperature kiln is introduced in low temperature kiln, green compact are heated, reduce heater and use
Electricity, thus reach the purpose of electricity saving and energy saving.It addition, being turned on and off of blower fan, it is according to thermocouple
The testing result of kiln in-furnace temperature is determined, such as, switch board sets the burning of Nixing pottery base substrate
Maximum temperature processed is 1120 DEG C, the most persistently fires 0.8 hour, when switch board (herein means height
Temperature kiln) receive thermocouple send temperature value signal arrive 1120 DEG C time, start timing, timing reaches
After 0.8 hour, close heater, stop kiln being heated, start blower fan, by high temperature kiln simultaneously
In interior high-temperature gas introduces low temperature kiln rather than as existing monomer kiln, open air vent,
High-temperature gas is expelled directly out, makes high-temperature gas can be used again Nixing pottery base substrate in low temperature kiln
Dehumidifying, be dried, and the dehumidifying temperature of Nixing pottery base substrate is generally about 100 DEG C, and needs slow
Slowly reaching this temperature, the time that dehumidifying is dried is the longest, the high temperature of slow cooling, discharge in high temperature kiln
Gas can meet the demand of low temperature kiln furnace heat completely.
Cooling characteristic according to the Nixing pottery after having fired and the dehumidifying of Nixing pottery base substrate, drying property,
Described ventilation mouth is the most all opened in the bottom of kiln.
In order to accurately control the change of kiln in-furnace temperature, that improves Nixing pottery base substrate further burns till rate
With fine work rate, the thermocouple in each kiln is preferably two, all by described transmitter and switch board
Input connect, one of them thermocouple be located at ventilation mouth at, another thermocouple is located under kiln
Portion.
The kiln wall of described kiln preferably includes internal layer high temperature foam brick, intermediate layer warming plate and layer structure wall
Brick.
In order to can more uniform lower the temperature in making high temperature kiln, can more uniform heat up in low temperature kiln, to enter
One step improves rate of burning till and the fine work rate of Nixing pottery base substrate, and described warm-air pipe stretches into the length in kiln at most
Half for kiln cavity length.
Described kiln is shuttle kiln.
Compared with prior art, each section of sintering process, according to Nixing pottery firing process feature, is entered by the present invention
Row level-density parameter: such as at high-temperature calcination stage (more than 1000 DEG C), be the opportunity of Nixing pottery generation transmutation,
In this time period, the deep low gear of blower fan can be started, make the high-temperature gas in high temperature kiln flow,
Strengthen the reducing atmosphere in high temperature kiln, to improve the transmutation rate of Nixing pottery, and high-temperature gas is introduced
In low temperature kiln, owing to low temperature kiln needs to heat slowly, high-temperature gas at this moment can meet low
The heat of temperature kiln needs；And after the Nixing pottery in high temperature kiln has been fired, enter temperature-fall period,
The high-temperature gas discharged increases, and the heat demand in low temperature kiln also increases, and both energy levels just mate；
The level-density parameter of two kilns, can arrange in switch board, make the shape of kiln atmosphere, air temperature and current
State is precisely controlled, burns till rate and fine work rate to improve.And it is simple numeric ratio that switch board runs
Relatively and control the rotating speed of blower fan, the target that calcination parameter controls is reached.
