Heated-air circulation ovenTechnical field
The utility model belongs to a kind of drying plant, specifically, particularly relates to a kind of heated-air circulation oven.
Background technology
Heated-air circulation oven is mainly used in being heating and curing of the industry materials such as medicine, chemical industry, food, agricultural byproducts, aquatic products, light industry, drying and dehydrating.Its general principle utilizes steam or electricity as heat energy, produces heat by steam radiator or electrical heating elements.Utilize blower fan to carry out heat convection, heat transmission is carried out to material, and constantly supplement fresh air and discharge humid air, time dry, in case, can suitable relative temperature and humidity be kept.The enterprises such as medication chemistry often need to dry chemical products with heated-air circulation oven, dry waste gas that chemical products produce without filtration and process by directly emptying, have not only wasted material but also contaminated environment.
Utility model content
The utility model object is to provide a kind of heated-air circulation oven, dries waste gas filtered and process that chemical products produce by directly emptying to overcome heated-air circulation oven in prior art, has not only wasted material but also the defect of contaminated environment.
The utility model realizes by the following technical solutions: a kind of heated-air circulation oven, comprise thermal-insulating body, thermal insulating door thermally insulated door and appliance controller, described thermal-insulating body is provided with air channel, air regulating board, heater, baking car, circulating fan, air inlet and moisture exhausting port, described air inlet and moisture exhausting port are respectively equipped with efficient air intake filter and high efficiency exhaustion filter, described high efficiency exhaustion filter is connected with retracting device.
The inner position, three, upper, middle and lower of described thermal-insulating body is respectively equipped with temperature probe.
Described thermal insulating door thermally insulated door is the left and right two-door structure being located at thermal-insulating body front.
Described heater is U-shaped.
Heat-insulation layer is provided with outside described air channel.
Compared with prior art, the beneficial effects of the utility model are: (1) the utility model is dried the waste gas that produces through high efficiency exhaustion metre filter and reclaimed through retracting device, decreases waste and avoids the pollution of air; (2) the utility model bake out temperature controls precisely, insulation good drying effect, and compares economize energy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of heated-air circulation oven, comprise thermal-insulating body 1, thermal insulating door thermally insulated door 2 and appliance controller 7, thermal-insulating body 1 is provided with air channel, air regulating board, heater 5, dries car, circulating fan 8, air inlet and moisture exhausting port, preferably heat-insulation layer is wrapped up outside air channel, to reduce the loss of heat, heater 5 preferably adopts U-shaped heater, heating effect is better, air inlet and moisture exhausting port are respectively equipped with efficient air intake filter 6 and high efficiency exhaustion filter 3, and high efficiency exhaustion filter 3 is provided with retracting device 4.
Thermal insulating door thermally insulated door 2 of the present invention is preferably the left and right two-door structure being located at thermal-insulating body 1 front.
Position, thermal-insulating body 1 of the present invention three, inner upper, middle and lower is also respectively equipped with temperature probe, the particular location of temperature probe is: the downward 200mm of top board is point for measuring temperature above, base plate upwards 200mm is point for measuring temperature below, center is middle point for measuring temperature, this kind of thermometric mode is convenient to the temperature difference in adjustment thermal-insulating body 1, and in thermal-insulating body 1, temperature controls more accurate.
Appliance controller 7 adopts PLC to control touch screen operation or shift knob controls, after setting temperature required value, when temperature rises to set temperature value, in temp controlled meter, relay accepts the automatic switching power supply of command signal of sensor, makes the magnetic valve in circuit or steam pipework and pneumatic operated valve open or close.
