[0042] like Figure 1 , Figure 2 As shown, the present invention provides a drying device with lifting and flipping functions, comprising:

[0043] Gantry 1;

[0044] The drying cylinder 2 is made of a transparent material. The drying cylinder 2 is arranged on the gantry 1 through a lifting structure. The left end of the drying cylinder 2 is provided with a material inlet and outlet and an air inlet. The right end of the drying cylinder 2 is provided with an exhaust port, and an exhaust fan is provided at the exhaust port.

[0045] The overturning structure is arranged on the gantry 1 and connected to the drying drum 2. The overturning structure drives the drying drum 2 to rotate so as to overturn the materials in the drying drum 2.

[0046] In the above embodiments, the gantry 1 includes a bottom frame and support rods. The support rods are vertically fixed at both ends of the bottom frame, and the support rods can be in an inverted L shape or a U shape. Optionally, two U-shaped support rods are vertically fixed at both ends of the bottom frame to form the gantry 1. The bottom frame can be rectangular. The drying cylinder 2 can be in a cylindrical structure. The drying cylinder 2 can be made of any light-transmitting material such as transparent plastic or glass. The lifting structure can be a winch mechanism, a hydraulic lifting mechanism or a similar mechanism. For example, when the lifting structure is a winch mechanism, the traction motor of the winch mechanism is fixed at the horizontal part of the U shape of the gantry. A rotating shaft is provided at the end of the drying cylinder, and a bearing is rotatably fixed on the rotating shaft so that the drying cylinder can rotate relative to the bearing. One end of the traction rope is connected to the bearing provided at the end of the drying cylinder, and the other end of the traction rope is connected to the traction motor. By winding the traction rope by the traction motor, the lifting of the drying cylinder 2 is realized without affecting the rotation of the drying cylinder. Optionally, the air inlet is provided on the upper side of the left end of the drying cylinder 2. The air inlet can be circular, square or triangular. The feeding and discharging port is provided on the lower side of the left end of the drying cylinder. The feeding and discharging port can be square or circular. The flipping structure can be a belt-driven flipping structure, including a driving device and a belt. The driving device can be a motor, an internal combustion engine, etc. The driving device is fixed on the gantry. One end of the belt is sleeved on the body of the drying cylinder or sleeved on the rotating shaft at the end of the drying cylinder, and the other end of the belt is sleeved on the driving device to drive the drying cylinder to rotate through the driving device. The flipping device can also be a driving wheel type flipping structure. Specifically, the driving device is fixed on the gantry, and a driving wheel is rotatably fixed on the gantry. The driving wheel abuts against the drying cylinder, and the output end of the driving device is fixedly connected to the driving wheel. When the driving wheel rotates, the drying cylinder is driven to rotate due to the frictional force between the driving wheel and the drying cylinder. In the present invention, the drying cylinder is arranged on the gantry through the lifting structure, so that both ends of the drying cylinder can move relative to the gantry. When the lifting structure lifts the left end of the drying cylinder, the left end of the drying cylinder tilts upward, which is convenient for loading materials into the drying cylinder. When the lifting structure lifts the right end of the drying cylinder, the left end of the drying cylinder tilts downward, which is convenient for discharging the materials in the drying cylinder. Through the combined action of the drying cylinder made of transparent material and the flipping structure in the present invention, centralized drying, one-time drying of materials and improvement of drying uniformity are realized.

By arranging a cylinder frame on the outside of the drying cylinder to support the drying cylinder, the requirements of the drying cylinder on the material structure strength can be reduced, and the production cost of the drying device can be reduced. The shape of the cylinder frame can be cylindrical. Optionally, the cylinder frame includes a plurality of axial rods and a plurality of radial rods, the axial rods are arranged along the length direction of the drying cylinder, and the plurality of axial rods are arranged at intervals along the circumferential direction of the drying cylinder.

[0052] The present invention realizes the lifting of the drying cylinder in the form of a wire rope being wound by a lifting motor. The connection structure is relatively simple, which helps to lift or lower the two ends of the drying cylinder respectively to adjust any height of the drying cylinder on the gantry, facilitating the loading and unloading of the materials in the drying cylinder. In some embodiments, the lifting structure can be a hydraulic lifting rod, that is, the hydraulic lifting rod is connected to the two ends of the drying cylinder, and the lifting functions of the two ends of the drying cylinder are respectively realized through the extension and contraction of the hydraulic lifting rod.

[0053] In another technical solution, the flipping structure includes: a flipping motor 4 and a transmission belt 9; the flipping motor 4 is arranged on the gantry 1 and above the drying cylinder 2, and the flipping motor 4 is connected to the main shaft 7 in the middle of the drying cylinder 2 through the transmission belt 9 to drive the drying cylinder 2 to rotate. Optionally, the flipping motor 4 is fixed above the horizontal bar of the U-shaped support rod.

By setting the flipping structure to drive the drying cylinder to rotate, the materials in the drying cylinder are flipped, and the materials continuously change positions in the drying cylinder, making the drying of the materials more uniform.

[0054] In another technical solution, at least one material turning plate 16 is arranged inside the drying cylinder 2, and the material turning plate 16 is arranged along the length direction of the drying cylinder 2. The shape of the material turning plate 16 can be rectangular. Optionally, a number of through holes are arranged on the material turning plate 16. By arranging through holes on the material turning plate 16, it helps to reduce the mass of the material turning plate 16 and further realizes the lightweight setting of the drying cylinder. By setting the material turning plate, the materials at the position of the drying cylinder wall can be better turned towards the inside of the drying cylinder, making the materials in the drying cylinder heat more evenly and improving the drying effect.

[0055] In another technical solution, the number of the material turning plates 16 is 3. The included angle between the two outer material turning plates 16 and the middle material turning plate 16 is 30 - 60°, and the height of the material turning plate is 1 / 3 - 1 / 2 of the radius of the drying cylinder. By limiting the number of the material turning plates, it can promote the materials at the drying cylinder wall to be better flipped to the middle of the drying cylinder, and the materials in the middle to be better flipped to near the drying cylinder wall, greatly improving the drying effect.

[0056] In another technical solution, a battery 12 and a control unit 13 are provided at the bottom of the gantry 1, and a humidity sensor and a temperature sensor are provided in the drying barrel 2.

The battery 12 can be fixed above the bottom frame or fixed below the bottom frame. The battery can be a ternary lithium battery, a lithium iron phosphate battery, or a lead-acid battery. The control unit can be fixed at any position on the gantry. The temperature sensor can be optionally fixed at the connection position between the flip plate and the drying barrel, and the humidity sensor can be optionally fixed on the inner wall of the drying barrel on the other side opposite to the position of the temperature sensor. By providing battery power supply, the use of the drying device does not depend on the use environment, that is, the material can be dried in places without power supply, so that the use range of the drying device is wider. The use of the control unit makes the drying device more automated and improves the drying efficiency by automatically controlling the operation of the exhaust fan, etc.

[0057] In another technical solution, the drying barrel 2 is connected to an auxiliary heating device. The auxiliary heating device may be an electric heating device, a magnetic heating device, a hot air furnace, etc. Specifically, when the auxiliary heating device is an electric heating device, the electric heating device is fixed to the inner wall of the drying barrel 2, and power is supplied to the electric heating device to make the electric heating device work, so as to provide heat to the inside of the drying barrel. By adding an auxiliary heating device, the material can be dried even in cloudy or rainy weather when the temperature in the drying barrel is low, avoiding damage to the material caused by the inability to dry the material due to weather reasons, thereby improving the practicality of the drying device.

[0058] In another technical solution, the drying cylinder 2 is connected to a hot air furnace to introduce hot air into the drying cylinder 2. Optionally, a hot air inlet is provided at the end of the drying cylinder, and the hot air inlet is connected to the hot air furnace through a pipeline, so that hot air can be provided to the drying cylinder. When it is rainy, cloudy or when there is insufficient sunlight, the hot air generated by the external hot air furnace can be introduced into the drying cylinder 2 to dry the materials in the drying cylinder 2. The hot air device can not only provide heat to the materials, but also use the hot air to take away the moisture in the drying cylinder, thereby improving the drying efficiency of the materials.

[0059] In another technical solution, the drying drum 2 has a length of 3-4 m and a diameter of 1-1.5 m. By controlling the length and diameter of the drying drum, the drying weight of the drying drum is controlled to be about 1-1.5 tons, which is convenient for the production of the drying device and its later movement.

[0060] In another technical solution, the volume of the material in the drying drum 2 is 1 / 3-1 / 2 of the volume of the drying drum 2. By controlling the filling volume of the material in the drying drum, the material in the drying drum can be turned over better, the drying efficiency of the material is improved, and the utilization rate of the drying device can be improved.
