A kind of automatic control air dry oven
Technical field
The utility model relates to a kind of drying box, is specifically related to a kind of automatic control air dry oven that can carry out temperature control voluntarily.
Background technology
At present, in the chemical products production process, often want some chemical products of forced air drying.Existing air dry oven variations in temperature is fast, the Artificial Control temperature, and operation is frequent and have a hysteresis quality.Heat waste is serious, and dry homogeneity is poor, and drying efficiency is not high.
Summary of the invention
The purpose of the utility model is customer service deficiency of the prior art and a kind of reasonable in design is provided; Can make the thermal current material surface of flowing through uniformly; It is high to improve drying efficiency, and attemperating unit has promptly been simplified operation simultaneously, has improved the automatic control air dry oven of the accuracy of temperature control again.
The purpose of the utility model is achieved in that a kind of automatic control air dry oven; Comprise drying box; Described drying box one side is provided with heater, and described drying box another side is provided with air outlet, and the drying box upper surface is provided with air inlet; Described drying box set inside has the blast fence one and blast fence two with the parallel sided that heater is installed; The outer surface of described drying box is provided with heat-insulation layer, on drying box, also is provided with thermocouple thermometer, between thermocouple thermometer and heater, is provided with temperature controller.
Described heater comprises steam inlet pipeline, steam pipe coil, steam outlet tube road; Wherein on steam inlet pipeline and steam outlet tube road, be respectively arranged with magnetic valve one and magnetic valve two; Described temperature controller is arranged between magnetic valve one and the thermocouple thermometer; Described steam inlet pipeline, steam pipe coil, steam outlet tube road are interconnected, and described steam pipe coil is embedded into the drying box side.
Described air outlet set inside has air-introduced machine.
Described air inlet is arranged on blast fence one and is inlaid with between the drying box side of steam pipe coil.
The utlity model has following advantage: the utility model provides a kind of steam that utilizes to be thermal source, air dry oven that can be temperature automatically controlled.Its reasonable in design can make the thermal current material surface of flowing through uniformly, and it is high to improve drying efficiency, and attemperating unit has promptly been simplified operation simultaneously, has improved the accuracy of temperature control again.
