Description of drawings

Fig. 1 is a schematic structural view of a hot air dryer in an embodiment of the present invention.

In the figure: 1. Fan; 2. Air duct; 3. First heating wire; 4. Raw material barrel; 5. Breathable support net; 51. Feeding port; 6. Second heating wire.

detailed description

Specific embodiments of the present utility model will be further described below in conjunction with accompanying drawings.

As shown in Figure 1, the hot air dryer in this embodiment includes a fan 1, an air duct 2, more than one heating wire, a raw material barrel 4 for holding heated materials, and a support for heated materials. The breathable support net 5 of the material; the fan 1 is located at the air inlet of the air duct 2, and the heating wire is arranged on the air duct 2; the top and the bottom of the raw material barrel 4 are provided with openings, and the air outlet of the air duct 2 communicates with the raw material barrel 4; The air-permeable support net 5 is a mesh structure, and is located in the raw material barrel 4. The air-permeable support net 5 is provided with a closable blanking opening 51, and the air outlet of the air duct 2 is located below the air-permeable support net 5. In the embodiment, the mesh opening size of the air-permeable support net is smaller than the size of the material to be heated.

Preferably, the hot air dryer in the embodiment includes two heating wires, respectively the first heating wire 3 and the second heating wire 6, which are arranged on the air duct between the fan 1 and the air outlet, and the two heating wires are spaced apart. some distance.

In order to facilitate the drying of the material directly out of the raw material barrel, preferably, the bottom of the raw material barrel 4 is conical. Preferably, the opening at the bottom of the raw material barrel 4 is located directly below the feeding opening 51 .

In order to save the occupied space of the equipment, preferably, the air duct 2 is L-shaped.

In the embodiment, the cold air enters the air duct 2 through the blower fan 1, dehumidifies and heats the air through the first heating wire 3, heats it up twice through the second heating wire 6, and enters the raw material barrel 4; the top of the raw material barrel 4 The opening is used to add raw materials therein; the raw materials fall on the breathable support net 5, the hot air entering the raw material barrel 4 rises, passes through the breathable support net, and heats the material in the raw material barrel during the rising process. The principle is to dry it; after drying, open the discharge port 51 on the ventilating support net 5, and the dried material is discharged through the opening at the bottom of the raw material barrel 4.

The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned embodiments. The various changes made below should also be regarded as the protection scope of the present utility model.
