[0020] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.
[0021] like Figure 1-7 As shown, the utility model provides a high-efficiency drying machine for ginkgo leaf processing, including a high-temperature drying device 1, a heat preservation device 2, and a water vapor exhaust device 3; the feed port of the heat preservation device 2 is connected to the discharge end of the high-temperature drying device 1, the water vapor exhaust device 3 is connected to the discharge end of the heat preservation device 2, and the discharge port at the lower end of the water vapor exhaust device 3 is connected to a discharge conveyor belt 4; the upper end of the high-temperature drying device 1 is connected to a feeding conveyor belt 5; the high-temperature drying device 1 includes a drying room 11, a feed hopper 12, a drying drum 13, and a discharge hopper 14; the feed The hopper 12 is installed on the top of the drying room 11 and docked with the loading conveyor belt 5. The lower end of the feed hopper 12 is docked with the feed end of the drying drum 13 installed inside the drying room 11; the drying drum 13 is rotatably installed on the support frame Ⅰ15 set on the inner wall of the drying room 11, and the outer wall of the drying drum 13 is provided with transmission teeth, which is connected to the motor Ⅰ16 installed on the top of the drying room 11 through gear transmission; the discharge end of the drying drum 13 is docked with the upper end of the discharge hopper 14, and the discharge hopper 14 is installed on the drying side wall, and the end is docked with the feed end of the insulation device 2. When the dryer is working, the fresh ginkgo leaves are conveyed to the feed hopper 12 through the feeding conveyor belt 5, and the ginkgo leaves enter the drying drum 13 along the feed hopper 12. The high temperature generated in the drying room 11 dries the ginkgo leaves in the drying drum 13. Under the drive of the motor Ⅰ16, the drying drum 13 is rotated to turn and stir the ginkgo leaves, so that the ginkgo leaves are evenly heated. Then, the dried ginkgo leaves enter the discharge hopper 14 from the discharge end, and enter the heat preservation device 2 through the discharge hopper 14 to be kept warm so that the water vapor in the ginkgo leaves evaporates, and the water vapor in the ginkgo leaves is discharged through the water vapor discharge device 3. The utility model adds the ginkgo leaves to the drying drum 13, and during the drying process, the drying drum 13 rotates to turn and stir the ginkgo leaves, so that the ginkgo leaves are evenly heated and can be evenly dried, so as to avoid that a part of the ginkgo leaves are heated less, resulting in insufficient drying and the need for repeated drying. The device dries the ginkgo leaves evenly and fully, and improves the drying efficiency of the ginkgo leaves.
[0022] The inner wall of the drying drum 13 is provided with a spiral blade Ⅰ131 and a stirring plate 132 parallel to the axis of the spiral blade Ⅰ131. When the ginkgo leaves are heated and dried in the drying drum 13, the drying drum 13 rotates, and the stirring plate 132 stirs and turns the ginkgo leaves, so that the ginkgo leaves are mixed and heated more evenly and dried more fully. Under the push of the spiral blade 131, the ginkgo leaves move toward the discharge end while being dried, so that the ginkgo leaves automatically enter the heat preservation device 2 for water vapor evaporation.
[0023] The support frame Ⅰ15 includes a support ring 151 and a support foot 152. The drying drum 13 is sleeved in the support ring 151 and is rollingly connected to a roller 153 provided on the inner wall of the support ring 151. One end of the support foot 152 is connected to the support ring 151, and the other end is connected to the inner wall of the drying room 11. The drying drum 13 is supported by the roller 153 in the support ring 151 and driven by the motor to rotate, flip the ginkgo leaves, and move the ginkgo leaves in the drying drum 13.
[0024] A drying furnace 17 is provided in the drying room 11, and the drying furnace 17 is connected to an addition port for adding burning charcoal provided on the side wall of the drying room 11. Coal is added to the drying furnace 17 through the addition port, and the coal is burned, and the drying furnace 17 generates heat to heat and dry the ginkgo leaves.
[0025] The heat preservation device 2 comprises a heat preservation drum 21 and a support frame II 22. The heat preservation drum 21 is rotatably mounted on a roller 23 arranged on the support frame II 22. A circular rail 24 is arranged on the outer wall of the heat preservation drum 21 to roll with an annular groove 25 on the roller 23. A motor II 26 is installed on the support frame II 22 to be connected to the roller 23. A spiral blade II 211 is arranged on the inner wall of the heat preservation drum 21. The dried ginkgo leaves enter the heat preservation device 2. The motor II 26 drives the roller 23 to rotate. The roller 23 drives the heat preservation drum 21 to rotate. The spiral blade 131 makes the ginkgo leaves gradually move forward. The ginkgo leaves gradually evaporate water vapor in the heat preservation device 2, thereby drying the ginkgo leaves.
[0026] The water vapor discharge device 3 includes a connecting pipe 31, a collecting cylinder 32, a fan 33, and a screw conveyor 34; one end of the connecting pipe 31 is rotatably connected to the discharge end of the heat preservation drum 21, and the other end is connected to the upper part of the side wall of the collecting cylinder 32. The fan 33 is installed at the air outlet opened at the top of the collecting cylinder 32; the screw conveyor 34 is installed at the bottom of the collecting cylinder 32 to transport the ginkgo leaves to the discharge conveyor belt 4. The fan 33 rotates at the upper end of the collecting cylinder 32 to generate airflow, so that negative pressure is generated in the connecting pipe 31, and the ginkgo leaves and water vapor in the heat preservation drum 21 are sucked into the collecting cylinder 32 through the connecting pipe 31. The water vapor is discharged from the upper end, and the ginkgo leaves automatically fall to the bottom of the collecting cylinder 32 due to gravity. Under the push of the screw conveyor 34, the dried ginkgo leaves are pushed to the discharge conveyor belt 4 and transported to the packaging machine for bagging and packaging.
[0027] The screw conveyor 34 is provided with a screw conveyor rod 341, which is in driving connection with a motor III 342 provided at the end of the screw conveyor 34. The motor III 342 drives the screw conveyor rod 341 to rotate, pushing the ginkgo leaves from the collecting barrel 32 to the discharging conveyor belt 4, thereby facilitating the control of the discharging speed of the ginkgo leaves.
[0028] Working process:
[0029] When the dryer is in operation, the fresh ginkgo leaves are conveyed to the feed hopper 12 through the feeding conveyor belt 5, and the ginkgo leaves enter the drying drum 13 along the feed hopper 12. The high temperature generated in the drying room 11 dries the ginkgo leaves in the drying drum 13. Driven by the motor Ⅰ16, the drying drum 13 rotates, and the ginkgo leaves are turned over and stirred, so that the ginkgo leaves are heated evenly. Then, the dried ginkgo leaves enter the discharge hopper 14 from the discharge end, and enter the heat preservation device 2 through the discharge hopper 14 for heat preservation to evaporate the water vapor in the ginkgo leaves. The water vapor in the ginkgo leaves is discharged through the water vapor discharge device 3, and the ginkgo leaves fall into the collecting cylinder 32 and are discharged from the bottom, thereby obtaining dry ginkgo leaves.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
