A kind of baking oven
Technical field
The utility model relates to a kind of drying unit, is a kind of baking oven specifically.
Background technology
Comprise electric dry oven, steam baking oven at the employed baking oven of chemical field at present, aborning especially based on the steam baking oven, but existing steam baking oven all is static drying mode, so not only needs to make steam consumption big but also drying time is long, can not reach the requirement of energy-saving and emission-reduction.
The utility model content
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, can energy savings, the baking oven that reduces cost.
Technical scheme: in order to solve the problems of the technologies described above, a kind of baking oven described in the utility model comprises the casing of being with door, and the air purification filter device is installed above casing, in the outside of casing blower fan, airduct is installed; Wherein have hot humid air outlet in the top of a face wall at casing, the import of described hot humid air outlet and air purification filter device is in the same side, bottom at the other face wall of casing is equipped with heater, and the port of export of air purification filter device links to each other with heater by blower fan, airduct successively; Also be provided with the function adjustable plate of the import and the outlet of hot humid air that are used for being communicated with, cutting off the air purification filter device in the outside of casing; In casing, be provided with Temperature Humidity Sensor, the controller that joins with Temperature Humidity Sensor is installed outside casing.
Operation principle of the present utility model is: existing static oven dry pattern is become dynamic oven dry pattern, that is: opening function adjustable plate at first, open blower fan, heater, make fresh air pass through blower fan successively by the import of air purification filter device, airduct, heater enters in the casing, hot then humid air is discharged from hot humid air outlet, after the humiture in the casing reaches setting value, the closing function adjustable plate, hot-air in the casing is by the casing that acts on of blower fan at this moment, air cleaning filter, blower fan, airduct, form hot air circulating system between the heater, again after the humiture in the casing reaches setting value, the open function adjustable plate, again after the humiture in the casing reaches setting value, the closing function adjustable plate, make the material in the casing in dynamic hot air circulating system, dry again, continuous above-mentioned steps repeatedly is till drying materials.
In order to gather the heat of baking oven, on described casing, be provided with heat-insulation layer.
In order to realize that the function adjustable plate regulates automatically, described Temperature Humidity Sensor joins by controller and function adjustable plate.
Easy for installation in order to make, described blower fan is installed in the top of casing.
Beneficial effect: compared with prior art, the utility model has the advantages that rational in infrastructurely, can save 10 tons of live steams every day, can save 500 tons of mark coals every year, thereby reduce cost; Adopt dynamic hot air circulating system, clean dry-heat air can be provided, can shorten drying time, improve the efficient of producing, can also reach the requirement of energy-saving and emission-reduction simultaneously.

Fig. 3 is the fundamental diagram of the utility model when the function adjustable plate is closed.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of baking oven of the present utility model comprises the casing 1 of being with door, and air purification filter device 2, blower fan 3 are installed above casing 1, in the outside of casing 1 airduct 4 is installed; The outlet of air purification filter device 2 links to each other with the import of blower fan 3, and the exit of blower fan 3 is connected with airduct 4; Wherein have hot humid air outlet 5 in the top of a face wall at casing 1, the import of hot humid air outlet 5 and air purification filter device 2 is equipped with heater 6 in the same side in the bottom of casing 1 an other face wall, and airduct 4 links to each other with heater 6; Outside at casing 1 also is provided with function adjustable plate 7, function adjustable plate 7 can be used for being communicated with, the import of partition air purification filter device 2 and hot humid air outlet 5, when the needs fresh air enters, function adjustable plate 7 is equalized, so just the import and the hot humid air outlet 5 of air purification filter device 2 can be separated, enter and make hot-air when needs stop fresh air at casing, air purification filter device 2, blower fan 3, when carrying out thermal cycle between airduct 4 and the heater 6, function adjustable plate 7 is erected, so just the import of air purification filter device 2 can be communicated with hot humid air outlet 5, thereby form hot air circulate; In casing 1, be provided with Temperature Humidity Sensor 8, the controller 9 that joins with Temperature Humidity Sensor 8 is installed outside casing 1.
On casing 1, be provided with heat-insulation layer.Temperature Humidity Sensor 8 is joined by controller 9 and function adjustable plate 7, so just can realize that the function adjustable plate automatically adjusts.Described heater 6 adopts steam heater, also can use various thermals source such as hot water heating, electrical heating.
Shown in Figure 2 is that fresh air enters in the baking oven, and hot humid air is discharged the state of baking oven.
Shown in Figure 3 is that fresh air stops to enter baking oven, and the hot-air in the baking oven carries out thermal cycle then.
The above only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
