In addition, the drying apparatus in this embodiment further includes support legs 12, as shown in fig. 2. Wherein, there are four support legs 12, and each support leg is respectively located a bight of drying box 1 bottom to install through the welding mode.
In addition, a rubber pad 11 is attached to the lower portion of each support leg 12.
Through the elasticity of each rubber pad 11, can reduce the vibration that drying equipment during operation produced effectively.
In addition, the present embodiment further provides an operation method of a drying apparatus, which includes the following steps:
I. the door 15 is first opened by the handle 10, and then the materials to be dried are put on the respective drying trays (i.e., the first drying tray 24, the second drying tray 37, and the third drying tray 38), and then the door 15 is closed.
II, opening the second motor 20, the second motor 20 drives the first gear 19 to rotate, then drives the second gear 34 to rotate, and then drives the sleeve 33 to rotate, thereby driving each drying disk to rotate, and the material rotates along with the drying disk.
And III, turning on the first motor 2, wherein the first motor 2 drives the first rotating shaft 25 to rotate, then drives the mounting block 29 to rotate, then drives the fixing rod 28 to rotate, and then drives the stirring rod 18 to rotate, so as to start stirring the materials.
Wherein, stirring rod 18 and each stoving dish rotate to opposite direction, have realized the intensive mixing of material, are favorable to material and hot-blast abundant contact, have improved drying efficiency to the material is the outside stoving keeps unanimous.
The opposite direction is adopted, for example, when the stirring rod rotates along the anticlockwise direction, each drying disk rotates along the clockwise direction; in contrast, when the agitating bar 18 is rotated in the clockwise direction, the respective drying trays are rotated in the counterclockwise direction.
Iv. open the cyclone 6, dehumidifier 8, blower 21, electric hot plate 22 and suction fan 23.
Firstly, the blower 21 blows the hot air inside the heating box 14 into the drying box 1 through the exhaust pipe 13, and the air inlet is arranged at the bottom of the drying box 1, so that the principle that the hot air rises is met, and the drying speed is accelerated.
The hot air carries the water vapor and dust on the materials to enter the cyclone dust collector 6 from the air suction pipe 3; the dust is separated by the cyclone dust collector 6 and falls into the dust collecting box 7 to be collected.
Then, the hot air enters the dehumidifier 8 through the first conveying pipe 4 to remove water vapor from the hot air.
Through the treatment of cyclone 6 and dehumidifier 8, greatly reduced the content of steam and dust in hot-blast, be favorable to promoting circulating hot air drying's effect, be favorable to getting rid of the dust on the material, promoted the quality of material.
Hot air enters the heating box 14 through the second conveying pipe 9 under the action of the suction fan, and is heated by the electric heating plate 22; finally, the heated hot air is re-introduced into the drying cabinet 1 through the exhaust duct 13 by the blower 21.
Therefore, the hot air circulation is realized in the process, the heat loss is reduced, and the energy utilization rate is improved.
The drying equipment in the embodiment is beneficial to energy conservation and emission reduction, and meanwhile, the drying cost is reduced.
It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
