Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Example 1: As Figures 1-4 ,include: A workbench 100 is provided, and a drying oven 110 is fixedly installed on the top of the workbench 100. The drying oven 110 is used to dry medicines. A first temperature sensor is fixedly installed on the inner wall of the drying oven 110. Electric heating elements are evenly fixedly installed on the inner wall of the drying oven 110. Ultraviolet disinfection lamps are evenly fixedly installed on the inner wall of the drying oven. The hot airflow circulation assembly includes an air pump 200, which is fixedly installed on the top outer wall of the drying chamber 110. The input end of the air pump 200 draws out the airflow from the right side of the drying chamber 110 through the circulation pipe 210 and the air outlet pipe, and then returns the airflow to the left inner wall of the drying chamber 110 through the air inlet pipe 250 for airflow circulation. The dryer assembly includes a dryer 300, two sets of dryers 300 are symmetrically arranged, a drying filter element 340 is fixedly installed on the inner wall of the dryer 300, and a drying plate 330 is inserted inside the drying filter element 340.

[0018] The specific application scenario of this embodiment is as follows: The workbench 100 provides a supporting foundation for the device, and the drying chamber 110 on top of it is the main space for drying medicines. The electric heating elements on the inner wall of the drying chamber 110 generate heat after being energized, heating the medicines inside. A first temperature sensor monitors the temperature inside the chamber in real time. In the hot air circulation assembly, when the air pump 200 is working, it draws air from the right side of the drying chamber 110 through the circulation pipe 210 and the outlet pipe. After processing, the air returns to the left side of the drying chamber 110 through the inlet pipe 250, forming a hot air circulation, making the temperature inside the chamber uniform and drying... In the dryer assembly, the drying filter element 340 and drying plate 330 in the dryer 300 work together to adsorb moisture in the airflow, ensuring the drying of the circulating airflow and improving the drying effect. By setting two sets of dryers 300, after one dryer 300 becomes saturated with water, it automatically switches to the other dryer 300 for drying and filtration. At the same time, the drying plate 330 dries the inside of the drying filter element 340. The water is discharged through the drain pipe 350, restoring the water absorption capacity of the drying filter element 340. The ultraviolet disinfection lamp is used to disinfect the medicine during the drying process.

[0019] Example 2: Figures 1-3 The front outer wall of the drying oven 110 is connected to the movable door 120 by a hinge. When the movable door 120 is closed, it is sealed to the inner wall of the drying oven 110. The drying oven 110 has an inlet on the left side and an outlet on the right side. Both the inlet and outlet have curtains 130 installed on their inner walls.

[0020] The specific application scenario of this embodiment is as follows: The movable door 120 at the front end of the drying chamber 110 rotates via a hinge and is sealed to the inner wall of the drying chamber 110 when closed, reducing heat loss inside the chamber. The door curtains 130 at the left inlet and right outlet of the drying chamber 110 can be automatically opened and closed when medicines are put in and out, which not only facilitates continuous feeding and discharging of medicines, but also reduces air exchange between the inside and outside of the chamber, maintains a stable temperature inside the chamber, and ensures that the drying process is not disturbed by the external environment.

[0021] Example 3: Figures 1-5The drying filter element 340 is annular and has several layers. A drying plate 330 is provided between adjacent layers of the drying filter element 340. The surface of the drying plate 330 has uniformly distributed through holes for water to drain from the drying filter element 340. The end of the dryer 300 is detachably fixed with an end cover plate 310 via a flange. Two branch pipes 320 are connected in series on the outer walls of the two end covers 310. The middle outer wall of the branch pipe 320 is connected to the right inner wall of the drying chamber 110 via an exhaust pipe 240. A first electric... The first humidity sensor 232 and the first check valve 233 are fixedly installed on the outer walls of both ends of the solenoid valve 231 and the diverter pipe 320. The diverter pipe 320 is used to guide the airflow in the exhaust pipe 240 to the interior of the two dryers 300. The return pipe 220 is connected in series on the left outer wall of the dryer 300. The second check valve 221 is fixedly installed at both ends of the return pipe 220. The middle part of the return pipe 220 is connected to the circulation pipe 210 at the input end of the air pump 200. The output end of the air pump 200 is connected to the air inlet pipe 250 between the left inner wall of the drying chamber 110.

[0022] The specific application scenario of this embodiment is as follows: The drying filter element 340 is annular and has several layers. The through holes on the surface of the drying sheet 330 between adjacent layers can discharge the moisture in the drying filter element 340. The air pump 200 drives the airflow. The airflow on the right side of the drying chamber 110 enters the diversion pipe 320 through the exhaust pipe 240. The first solenoid valve 231 controls the airflow rate. The diversion pipe 320 guides the airflow to the two dryers 300. When the airflow passes through the multiple layers of drying filter element 340 and drying sheet 330, the water vapor is fully adsorbed. The first humidity sensor 232 monitors the humidity of the airflow after drying. The first check valve 233 prevents the airflow from flowing back. The dried airflow enters the air pump 200 through the return pipe 220 and the circulation pipe 210, and then flows back to the drying chamber 110 through the air inlet pipe 250. The second check valve 221 prevents the airflow from flowing back, ensuring stable and efficient drying cycle. The end cover plate 310 is detachable through the flange, which facilitates the replacement of the drying filter element 340 and the drying sheet 330.

[0023] Example 4: Figure 3 and Figure 4 A drain pipe 350 is fixedly connected to the bottom outer wall of the dryer 300, a drain valve 351 is fixedly installed on the outer wall of the drain pipe 350, and a water collection tray 360 is provided below the drain pipe 350.

[0024] The specific application scenario of this embodiment is as follows: the liquid water generated by the dryer 300 during the adsorption of water vapor is collected through the drain pipe 350 at the bottom. Opening the drain valve 351 can drain the water into the water collection tray 360 below, realizing the centralized collection and treatment of water, avoiding the accumulation of water in the dryer 300 and affecting the drying effect, and facilitating regular cleaning. All components involved in this utility model are externally connected to the controller in a conventional manner. The above structures and principles are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

The air pump 200 of the hot air circulation assembly operates, drawing air from the right side of the drying chamber 110 through the circulation pipe 210. After being processed by the dryer assembly, the air flows back to the left side of the drying chamber 110 through the air inlet pipe 250 to form a circulation. The drying filter element 340 in the two sets of dryers 300 adsorbs water vapor, the drying plate 330 assists in water removal, the diversion pipe 320 guides the airflow, the first solenoid valve 231 controls the flow, the first humidity sensor 232 monitors the humidity, the first check valve 233 and the second check valve 221 prevent the airflow from flowing back, and the drain pipe 350 and drain valve 351 at the bottom of the dryer 300 drain water into the water collection tray 360.
