Door.
The hydrofuge air channel is provided with air-valve, and electric control gear connects the air-valve.
The utility model has the following advantages：
The utility model is case structure, simple in construction, easy to remove, can be according to using needing to be moved to different fields
Close.The utility model is heated using ptc heater, and PTC has certain Curie point, more than this temperature spot, PTC
Electric current can drastically reduce, therefore will prevent that ptc heater peripheral temperature is too high, avoid the occurrence of Mars, prevent fire,
Improve the safe coefficient of drying course.
Air mixing cabin will uniformly be mixed by the air of ptc heater, make the air themperature humidity into hothouse equal
It is even, ensure the drying quality of material.
It know humiture situation in air -return duct due to that can be popped one's head in by humiture, therefore can be with using the utility model
Make drying course and the humiture situation of reality more adaptable.
Brief description of the drawings
Fig. 1 is circuit catenation principle figure of the present utility model；
Fig. 2 is structural representation of the present utility model.
Embodiment
Direction shown in arrow is airflow direction in Fig. 2.
As depicted in figs. 1 and 2, the box drying system of the present utility model based on PTC heating includes casing 1, and casing 1 is left
Portion is provided with vertical demarcation strip 2, and casing 1 is divided and is located at the first chamber for first chamber and second chamber, second chamber by vertical demarcation strip 2
On the right side of room；Second chamber internal upper part is provided with horizontal splitter plate 3, and second chamber is divided into positioned at horizontal splitter plate 3 by horizontal splitter plate 3
The air -return duct 4 of top and the hothouse 5 positioned at the lower section of horizontal splitter plate 3, the left end of horizontal splitter plate 3 are connected with vertical demarcation strip 2
Connect, there is gap between the right-hand member of horizontal splitter plate 3 and the right wall of casing 1；
First chamber middle and upper part is provided with ptc heater 6, and first chamber is divided into return air storehouse 7 and air mixing cabin by ptc heater 6
8；The through hole of return air storehouse 7 and air -return duct 4 is communicated with vertical demarcation strip 2（It is routine techniques that through hole is set on platy structure,
The not shown through hole）, return air storehouse 7 is interior to be provided with hydrofuge air channel 9, and casing 1 is stretched out in hydrofuge air channel 9 to the left, and the right-hand member in hydrofuge air channel 9 opens
Mouthful；The blower fan 10 being connected on vertical demarcation strip 2 is provided with air mixing cabin 8, the outlet of blower fan 10 is connected with hothouse 5；
