Description
Technical field
The utility model relates to a kind of roasting kiln, and especially circulate roasting kiln.
Background technology
When manufacturing refractory material, the aridity of raw material is very large to the quality influence of refractory product, existing roasting kiln can accurately not control the aridity of raw material when drying, the temperature and time of drying relies on the experience of workman to control, and the uniformity of kiln temperature and change air quantity and all can not accurately control, and causes the automaticity of producing low, drying effect is unstable, affect product quality, energy consumption is large simultaneously, and cost of use is high.
Utility model content
For solving the problem, the utility model provides the circulation roasting kiln that a kind of automaticity is high, good drying effect, energy consumption are low, and concrete technical scheme is:
Circulation roasting kiln, comprises conveyer belt and baking zone, and described baking zone two ends are preheating zone and radiating area, and described conveyer belt is located in preheating zone, baking zone and radiating area;
Also comprise heating air duct, frequency conversion centrifugal blower and humidity sensor;
Described heating air duct many groups is distributed in the side of baking zone side by side, heating air duct air outlet is located on the inwall of baking zone, heating air duct is connected with the hot air intake of radiating area by hot gas duct, there is frequency conversion fan the junction of heating air duct and hot gas duct, have heater between frequency conversion fan and heating air duct air outlet, there is temperature sensor at heating air duct air outlet place;
Baking zone opposite side has inlet scoop, and there are humidity sensor and temperature sensor in inlet scoop place;
The both sides of preheating zone are respectively blowing mouth and exhaust outlet;
Described frequency conversion centrifugal blower connects the inlet scoop of baking zone and the blowing mouth of preheating zone respectively by pipeline;
The opposite side of radiating area has cold wind import;
Described frequency conversion centrifugal blower, humidity sensor, temperature sensor, frequency conversion fan are connected with control system respectively with heater.
Described heater is heater strip or heating tube.
During use, radiating area is from cold wind import inspiration cold air, and cold air is to the heat radiation of roasted raw material, and cold air becomes hot-air.The hot-air of radiating area to be drawn onto in heating air duct by frequency conversion fan and to heat by baking zone, then blows to baking zone.Moisture in raw material is become steam and takes away by hot-air, hot-air containing steam is siphoned away by frequency conversion centrifugal blower and blows to preheating zone, the raw material to be dried of hot air preheating zone, hot-air becomes cold air, and the cold air containing steam is discharged by exhaust outlet.By recycling hot-air, greatly reduce energy consumption and operating cost.
The data that control system detects according to humidity sensor and temperature sensor and the difference of setting value control heater crawl and heat and provide institute's calorific requirement, the rotating speed of control frequency conversion fan and frequency conversion centrifugal blower simultaneously, thus change air quantity in control kiln.Temperature and to change Boiler pressure control accurate, heats save electricity by crawl simultaneously.
Many groups heating air duct the mode of column distribution improves kiln temperature uniformity.
The circulation roasting kiln structure that the utility model provides is simple, drying effect good, temperature homogeneity good, automaticity is high, energy consumption is low and use cost is low, save electricity 40%.
