[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] Example 1: Reference Figure 1-3 A plate material drying kiln comprises a kiln body 1, a cover 2 is hinged at one end of the kiln body 1, an inner cylinder 13 is rotatably installed inside the kiln body 1, a heat transfer oil pipe 3 is fixedly installed inside the inner wall of the kiln body 1, the inside of the heat transfer oil pipe 3 is used to transport heat transfer oil, the end of the heat transfer oil pipe 3 is connected to an external oil storage device through a circulation pump, the external oil storage device is provided with a device for heating it, the heat transfer oil inside the oil storage device is heated by the heating device, the heated heat transfer oil can be circulated through the heat transfer oil pipe 3, when the heat transfer oil pipe 3 transports the heat transfer oil, the heat transfer oil can transfer heat to the kiln body 1 during the flow, the heat transfer oil pipe 3 is bent and spirally arranged in the inner wall interlayer of the kiln body 1, so that the inside of the kiln body 1 can be heated evenly, and the raw materials inside the kiln body 1 can be heated more evenly.

[0016] A rotating support mechanism is fixedly installed on the outer surface of the kiln body 1, and the rotating support mechanism is connected to the inner cylinder through the rotating support mechanism, and the inner cylinder 13 can be driven to rotate. The rotating support mechanism includes a gear ring 4, which is coaxially arranged with the inner cylinder 13 and fixedly installed on the outer surface of the inner cylinder 13. A spur gear 5 is meshed at the bottom of the gear ring 4, and the spur gear 5 passes through the inner wall of the kiln body 1. Figure 1 As shown, the spur gear 5 is rotatably arranged on the upper surface of the base 6, and the end of the spur gear 5 is fixedly connected to the external motor. The external motor can drive the spur gear 5 to rotate, and the rotation of the spur gear 5 can drive the gear ring 4 to rotate. The rotation of the gear ring 4 can drive the inner tube 13 to rotate. The rotation of the kiln body 1 will drive the raw materials placed inside it to rotate.

[0017] A limit seat 8 is fixedly installed on the upper surface of the base 6, and a ring 7 is also fixedly installed on the outer surface of the kiln body 1. One side of the limit seat 8 cooperates with the inside of the ring 7. The limit seat 8 and the ring 7 cooperate with each other to support and fix the entire kiln body.

[0018] A support seat 9 is fixedly installed inside the inner cylinder 13, and a placement rack 10 is placed on the upper end of the support seat 9. The placement rack 10 is used to place the plates to be dried. The placement rack 10 has multiple layers, and the placement rack 10 is in the shape of a rectangular parallelepiped. Except for the five surfaces close to the cover 2, the other five surfaces are blocked by the rod body. The fixed blocking by the rod body will not affect the heating of the plates, but also can support the plates safely, and can prevent the plates from falling from the placement rack 10 during the rotation process. In addition, multiple layers of plates can be placed in the placement rack 10, and there are gaps between each plate, so that all surfaces of each plate can be exposed in the kiln body 1, which can improve the efficiency of heating. A clamping seat 11 is fixedly installed on the lower surface of the placement rack 10, and the lower end of the clamping seat 11 is slidably sleeved on the outer side of the upper end of the support seat 9. The placement rack 10 is slidably sleeved on the upper end of the support seat 9 through the clamping seat 11. The placement rack 10 can be clamped and fixed through the support seat 9 to prevent the placement rack 10 from shaking and deviating in the kiln body 1 during rotation. A roller 12 is also fixedly installed on the lower surface of the placement rack 10. When the placement rack 10 moves on the upper surface of the support seat 9, it can be pushed more conveniently through the support of the roller 12, which saves effort.

[0019] Working principle: During the operation of the plate raw material drying kiln, the plate is placed in the placement rack 10, and then the placement rack 10 is placed in the inner cylinder 13 through the holder 11 and the support seat 9. The placement rack 10 is pushed deep into the inner cylinder 13 under the support of the roller 12, and the circulation pump connected to the heat transfer oil pipe 3 is started. The heat transfer oil is heated by the heating equipment, and the heat transfer oil is transported by the heat transfer oil pipe 3. The kiln body 1 and the inner cylinder 13 are heated by the heat transfer oil, and the temperature inside the inner cylinder 13 will increase. The external motor is started to drive the spur gear 5 to rotate, and the rotation of the spur gear 5 will drive the gear ring 4 to rotate, and the rotation of the gear ring 4 will drive the inner cylinder 13 to rotate. When the inner cylinder 13 rotates, its interior can be evenly and fully heated by the heating oil pipe 3, and the rotation of the inner cylinder 13 will drive the placement rack 10 to rotate through the support seat 9 and the holder 11. The placement rack 10 will drive the plate to rotate during the rotation process. The plate can be heated evenly during the rotation process, which can improve the drying effect of each plate.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
