[0015] Reference Figure 1-6 The present invention proposes a pharmaceutical production electric heating drying oven, which mainly consists of an equipment box 1, several sets of multi-layer drug carriers 2, an electric heating blowing device 3, and a recovery device 4. The specific scheme is as follows: The equipment box 1 is equipped with a partition 11, which divides the interior of the equipment box 1 into a drying chamber 12 and an equipment chamber 13. The drying chamber 12 is used to place several sets of multi-layer drug carriers 2, providing a place for drug drying. The equipment chamber 13 is used to install an electric heating blower 3. At the same time, ventilation windows 14 are installed on both sides of the equipment chamber 13. The ventilation windows 14 can ensure the air circulation in the equipment chamber 13, which is convenient for the normal operation and heat dissipation of the electric heating blower 3. The multi-layer drug carrier 2 includes a guide rail 21 installed on the bottom surface inside the drying chamber 12. The front end of the guide rail 21 is connected to a forward stop plate 211, which prevents the movable shelf 22 from exceeding the safe range when moving forward. The rear end of the guide rail 21 has a slot 212, and the side of the rear end is rotatably connected to a rear stop plate 213. When the movable shelf 22 moves to the appropriate position, the rear stop plate 213 can be inserted into the slot 212 to fix the position of the movable shelf 22. The movable shelf cart 22 is pushed into the drying chamber 12 along the guide rail 21. The interior of the movable shelf cart 22 is provided with several layers of transfer boxes 23. The interior of the transfer box 23 is connected with several protruding pillars 231. These protruding pillars 231 are used to support the cover plate 24 so that the cover plate 24 will not bend or deform under pressure. The cover plate 24 is installed on the transfer box 23. A positioning groove 241 is opened on its upper surface. The positioning groove 241 is adapted to the medicine box 26 and can lock the medicine box 26 into place on the upper part of the cover plate 24. Several diversion holes 25 are also opened inside the cover plate 24. Several air inlets 261 and air outlets 262 are opened at the bottom and top of the medicine box 26 respectively. The positions of the diversion holes 25, air inlets 261 and air outlets 262 are in a one-to-one correspondence. Hot air enters the medicine box 26 through the diversion holes 25 and air inlets 261 in sequence, dries the medicine, and is discharged from the air outlets 262. The front end of the movable shelf vehicle 22 is equipped with an air inlet split pipe 27 with several air outlets. Each air outlet is connected to a corresponding transfer box 23. The front end of the air inlet split pipe 27 is connected to a secondary air inlet pipe 28. The outside of the secondary air inlet pipe 28 is connected to an annular locking protrusion 281. The annular locking protrusion 281 is an elastic locking structure that is adapted to the annular groove 37 on the air outlet split pipe 36, which facilitates the docking and separation of the air inlet pipe 28 and the air outlet split pipe 36. The electric heating blower 3 includes a fan 31 and an electric air heater 32 installed inside the equipment chamber 13. The air inlet of the fan 31 is connected to a main air inlet pipe 33, which extends to the outside of the equipment box 1 and is equipped with an air filter 34. The air filter 34 filters the air entering the fan 31, removing dust, impurities, etc., to ensure the cleanliness of the hot air. The air outlet of the fan 31 is connected to the air inlet of the electric air heater 32, which heats the incoming air into hot air. Its specific structure and principle are existing known technologies, and are not described here. Further details are omitted; the air outlet of the air heater 32 is connected to the air outlet pipe 35. The air outlet pipe 35 has several air outlets, each of which is connected to the air outlet diversion pipe 36. The inner side of the end of the air outlet diversion pipe 36 has an annular groove 37 that matches the annular locking protrusion 281. Through the cooperation between the annular locking protrusion 281 and the annular groove 37, the air outlet diversion pipe 36 and the air inlet pipe 28 can be connected by plugging in. The elasticity of the annular locking protrusion 281 seals the connection, allowing hot air to be smoothly delivered to the air inlet diversion pipe 27 and then enter each transfer box 23. The recycling device 4 includes a recycling box 41 installed at the top inside the equipment box 1. The lower surface of the recycling box 41 has several recycling holes 42 that communicate with its interior. These recycling holes 42 can collect the hot air discharged from the vent 262 of the medicine box 26. The upper surface of the recycling box 41 is connected to a recycling pipe 43 that communicates with its interior. The vent end of the recycling pipe 43 extends to the outside of the equipment box 1. The recycling pipe 43 can be connected to an external pipeline so that the used hot air can be used in other equipment for secondary utilization. During operation, the medicine to be dried is first placed in the medicine box 26, and then the medicine box 26 is placed in the positioning groove 241 of the cover plate 24. Next, the movable shelf 22 is pushed into the drying chamber 12 along the guide rail 21 until it reaches the appropriate position. The rear stop plate 213 is inserted into the slot 212 to fix the movable shelf 22. After the movable shelf 22 is pushed into place, the air inlet pipe 28 will connect with the air outlet diversion pipe 36 through the annular locking protrusion 281 and the annular groove 37. Because of the locking action, the connection will not be separated. Then the door of the equipment box 1 is closed. The electric heating blower 3 is started. The blower 31 draws in outside air through the air inlet pipe 33. After being filtered by the air filter 34, the air is sent to the air electric heater 32 for heating to form hot air. The air electric heater 32 has temperature setting and monitoring functions, which are existing known technologies and will not be described in detail here. The hot air enters the air outlet diversion pipe 36 through the air outlet pipe 35, and then is delivered to each transfer box 23 through the air inlet pipe 28 and the air inlet diversion pipe 27. The hot air is evenly distributed to the bottom of the medicine box 26 through the diversion hole 25 on the cover plate 24, and then enters the medicine box 26 through the air inlet 261 to dry the medicine. The dried exhaust gas is discharged from the air outlet 262, enters the recovery box 41 through the recovery hole 42, and finally exits the equipment box 1 through the recovery pipe 43. In addition, a sensor for monitoring temperature is also installed in the drying chamber 12, which will not be described in detail here. After drying is completed, wait for the internal temperature of the drying chamber 12 to reach room temperature, open the door of the drying chamber 12, flip the back stop plate 213 to disengage from the slot 212, and then pull the multi-layer drug carrier 2 out of the drying chamber 12. At the moment the multi-layer drug carrier 2 is pulled to move, due to the intervention of external force, the annular locking protrusion 281 will separate from the annular groove 37, thereby realizing the separation of the air inlet pipe 28 and the air outlet diversion pipe 36.
