[0002] Jingli is a traditional Chinese medicinal herb derived from the stems of Vitex negundo or Vitex malvaceae, both members of the Verbenaceae family. Processing involves roasting the stems in an oven, causing the juice to flow from both ends. This process is then collected in a container. This is a traditional method of preparation, utilizing the heat of fire to extract the juice from the stems.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Example

[0023] See also Figure 1-5 The utility model provides a technical solution: a Jingli oven exhaust gas recovery and reprocessing device, comprising an oven 1, wherein two drying chambers 2 are provided on the top of the oven 1, wherein one of the two drying chambers 2 is used for medium-heat drying and the other for high-heat drying, wherein a preheating chamber 3 is provided inside one of the drying chambers 2, and the preheating chamber 3 is located inside the medium-temperature drying chamber 2 of the two drying chambers 2, and the exhaust gas generated in the two drying chambers 2 can be transported to the preheating chamber 3, thereby conducting the remaining heat of the exhaust gas to the drying chamber 2 through the heat conduction plate 4 for auxiliary drying and heating;

[0024] The interior of the preheating bin 3 is provided with a cleaning component for cleaning impurities, and the cleaning component includes slag discharge holes 301 arranged on both sides of the inner wall of the preheating bin 3. The control valve inside the slag discharge hole 301 is used to regularly open and close and discharge the cleaned impurities from the preheating bin 3. The inner wall of the preheating bin 3 is provided with a heat conducting plate 4; the inner wall of the preheating bin 3 is provided with a chute 5 for limiting the angle of the slider 6 and the scraper 601 when they move. The inner wall of the chute 5 is provided with an annular groove 501, which is provided with a ring groove 501. The two ends of the annular groove 501 are connected. An electromagnet 502 is provided on the inner wall of the annular groove 501. After activation, the electromagnet 502 can generate magnetic poles and magnetically repel the magnetic plate 701 extending to the outer wall of the top block 7 inside the annular groove 501. A slider 6 is provided inside the chute 5. Scrapers 601 are provided at both ends of the slider 6. When the slider 6 moves in the chute 5, it drives the scrapers 601 to move and scrape off the impurity particles attached to the heat conducting plate 4 and push them to the slag discharge holes 301 on both sides of the inner wall of the preheating chamber 3.

[0025] A top block 7 is provided on the top of the slider 6. The top block 7 extends from the top of the slider 6 and is embedded in the annular groove 501. Magnetic plates 701 are provided on both sides of the top block 7. Support rods 702 are provided on the inner walls of the two magnetic plates 701. An air chamber 8 is provided inside the top block 7. The air chamber 8 is loaded with inert gas. When the exhaust gas enters the preheating chamber 3, the residual heat of the exhaust gas will heat the gas in the top block 7. After heating, the inert gas expands and pushes the piston to cooperate with the support rod 702 to drive the magnetic plate 701 to rotate and extend from the outer wall of the top block 7. The tilt angle is coordinated with the repulsive force of the electromagnet 502 to make the top block 7 slide in a cycle inside the annular groove 501, and at the same time drive the slider 6 to move back and forth in the slide groove 5, so that the heat of the exhaust gas is used as the driving source of the slider 6.

[0026] In this embodiment, all electrical components are controlled by conventional controllers.

[0027] For example, please refer to Figure 1-5, the two drying bins 2 are both equipped with air pipes, and the outlet of the air pipe extends to the preheating bin 3 on the top of one of the drying bins 2, the two slag discharge holes 301 are respectively located on both sides of the inner wall of the preheating bin 3, and a control valve is installed inside the slag discharge hole 301, the slider 6 is located in the chute 5, and is slidably connected to the inner wall of the chute 5, one end of the scraper 601 is connected to the outer wall of the slider 6 by a bolt, and the other end extends to the inner wall of the preheating bin 3 and fits with the heat conducting plate 4, the annular groove 501 is distributed in an annular manner on the inner wall of the chute 5, and is circulated and connected, the electromagnet 502 is inlaid with the inner wall of the annular groove 501, and the electromagnet 502 is connected to the annular groove 501. The magnetic plate 701 outside the slider 6 in the groove 501 is magnetically connected, one end of the top block 7 is embedded in the top of the slider 6 and is slidably connected to the inner wall of the slider 6, and the other end extends into the annular groove 501 and is slidably connected to the annular groove 501. When the slider 6 slides in the slide groove 5, the angle of the annular groove 501 cooperates with the top block 7 to make the slider 6 move back and forth in the slide groove 5. The two magnetic plates 701 are respectively located on both sides of the top block 7, and are both rotatably connected to the top block 7 through a connecting shaft. One end of the support rod 702 is embedded in the inner wall of the magnetic plate 701 and is slidably connected to the magnetic plate 701, and the other end extends into the air chamber 8 and is connected to the piston. The air chamber 8 is loaded with inert gas. When in use, the jingli is first placed in the two drying bins 2 in turn for two dryings. During the drying process, the exhaust gas generated by baking in the two drying bins 2 is injected into the preheating bin 3 of one of the drying bins 2 through the air pipe. When the exhaust gas enters the preheating bin 3, the remaining heat of the exhaust gas will be transferred to the drying bin 2 through the heat conduction plate 4 for auxiliary heating. At the same time, the heat of the exhaust gas will heat the gas in the top block 7 to cause it to expand and push the magnetic plate 701 and the top block 7 to rotate and tilt out through the piston and support rod 702. The electromagnet 502 is activated and generates magnetic poles through the PLC controller. The angle of the magnetic plate 701 and the repulsive force between the electromagnet 502 and the magnetic plate 701 drive the top block 7 to circulate in the annular groove 501, and at the same time drive the slider 6 to slide back and forth in the slide groove 5. When the slider 6 moves, the scraper 601 scrapes the impurities remaining on the heat conduction plate 4 into the slag discharge hole 301; the control valve in the slag discharge hole 301 is controlled by the PLC controller to open periodically for slag discharge.

[0028] The working process of the present invention is as follows: when in use, the jingli is first placed in the two drying bins 2 in turn for drying twice. During the drying process, the exhaust gas generated by baking in the two drying bins 2 is injected into the preheating bin 3 of one of the drying bins 2 through the air pipe. When the exhaust gas enters the preheating bin 3, the remaining heat of the exhaust gas will be transferred to the drying bin 2 through the heat conduction plate 4 for auxiliary heating. At the same time, the heat of the exhaust gas will heat the gas in the top block 7 to cause it to expand and push the magnetic plate 701 and the top block 7 to rotate and tilt out through the piston and the support rod 702, and the electromagnet 502 is controlled by the PLC controller to activate and generate magnetic poles. The angle of the magnetic plate 701 and the repulsive force between the electromagnet 502 and the magnetic plate 701 drive the top block 7 to circulate in the annular groove 501, and at the same time drive the slider 6 to slide back and forth in the slide groove 5. When the slider 6 moves, the scraper 601 scrapes the impurities remaining on the heat conduction plate 4 into the slag discharge hole 301; the control valve in the slag discharge hole 301 is controlled by the PLC controller to open periodically for slag discharge. The utility model realizes the recovery of the waste gas generated during the baking of jingli for auxiliary heating utilization, and reuses the heat as a driving source for the movement of the scraper, driving the scraper to clean the particulate impurities generated by the waste gas in the preheating bin, avoiding the accumulation of impurities, improving the utilization rate and ensuring the conduction effect of the waste gas heat.
