Preferably, the air source heat pump host (1) is half buried in the closed drying room (2), the air outlet (4) and the air return opening (5) are both arranged in a closed space and form an included angle of 90 degrees, the air outlet (4) and the air return opening (5) do not have heat exchange with an external space, the loss of waste heat is avoided, and the heat recovery efficiency is highest.
Preferably, baking house (2) adopt the polyurethane heated board to build in order can dismantling, and not only it is respond well to keep warm, and transportation, installation, the dismantlement of heated board material are all very convenient moreover, and the polyurethane heated board can also reuse, effective reduce cost.
Preferably, both sides of the drying room (2) are provided with observation windows (12) so as to observe the drying condition of the materials at any time.
Preferably, baking house (2) adopt intermediate bottom (10) and push-and-pull door (15) to separate baking house (2) for controlling two regions, and push-and-pull door (15) adopt handle (14), gyro wheel (16), upper guideway (9) and lower guideway (17) to realize closing, and the material car can freely push away arbitrary one region when push-and-pull door (15) are opened, and regional mutual noninterference in both sides when push-and-pull door (15) are closed, and hot-blast can not form the sinuous flow, leads to the stoving effect to worsen.
Preferably, regional diagonal angle in both sides all disposes a set of fan frame (6) in baking house (2), and fan frame (6) are from top to bottom, left and right sides direction evenly arranges certain quantity of internal recycle fan (7), and the air-out wind direction of internal recycle fan (7) is opposite, has formed 360 heated air circulation of level in whole baking house (2), and internal recycle fan (7) evenly arrange, guarantees that there is not dead angle in whole baking house (2), and the amount of wind is more even and stable.
Preferably, the material trolley (3) is integrally of an assembly type structure, is convenient to transport, mount and dismount, can be pushed in any direction by adopting universal wheels (13), is more labor-saving, and can be matched with material trays of various forms to adapt to different materials.
Preferably, the contact area of the fins of the U-shaped fin type electric heating pipe (11) and the circulating air is wide, so that the U-shaped fin type electric heating pipe can quickly assist the air source heat pump host (1) in increasing the temperature in the drying room (2).
Compared with the prior art, the invention has the following advantages:
the drying device has the advantages of simple structure, wide application, good heat preservation effect compared with the traditional drying mode, high drying efficiency, good finished product quality, energy conservation, environmental protection and effective reduction of drying cost.

Fig. 2 is a cross-sectional view a-a of fig. 1.
Fig. 3 is a front view.
In the figure: the device comprises an air source heat pump host 1, an air source heat pump drying room 2, a material trolley 3, an air outlet 4, an air return opening 5, an air blower frame 6, an internal circulation fan 7, a drying room door 8, an upper guide rail 9, a middle partition plate 10, a U-shaped fin type electric heating tube 11, an observation window 12, a universal wheel 13, a handle 14, a sliding door 15, a roller 16 and a lower guide rail 17.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The device comprises an air source heat pump host 1, an air source heat pump drying room 2, a material trolley 3, an air outlet 4, an air return opening 5, an air blower frame 6, an internal circulation fan 7, a drying room door 8, an upper guide rail 9, a middle partition plate 10, a U-shaped fin type electric heating tube 11, an observation window 12, a universal wheel 13, a handle 14, a sliding door 15, a roller 16 and a lower guide rail 17.
As shown in fig. 1: the air source heat pump side air supply type dryer comprises an air source heat pump host (1), a drying room (2), a material vehicle (3), an internal circulation fan (4) and an electric auxiliary heating device (5). The air source heat pump host (1) is half buried in the closed drying room (2); the drying room (2) is a closed drying room (2) built by polyurethane insulation boards and is provided with a drying room door (8) and an observation window (12); the material trolley (3) is a movable trolley, and a material tray can be loaded on the trolley.
The implementation process of the invention is as follows: the air source heat pump side air supply type dryer generates heat by the action of an air source heat pump host machine (1), the heat enters a closed drying room (2) from an air outlet (4), the heat is uniformly and stably blown to the surface of a material by an internal circulation fan (7), the moisture on the surface of the material is evaporated and taken away, and the moisture enters the air source heat pump host machine (1) from an air return opening (5) to remove moisture, so that the purpose of drying the material is achieved; two sets of internal circulation fans (7) of (2) in the closed drying room are respectively arranged at opposite angles of two sides of the drying room (2), and the air outlet directions are opposite, so that 360-degree circulating air of a side air supply type is formed in the whole drying room (2), the material is always in a hot air state, the retention time of moisture on the surface of the material is short, the material is guaranteed not to mildew, and the drying quality is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
