[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] like Figure 1 - Figure 7 As shown, a multi-partition vacuum drying box proposed by the present invention includes a shell 1, a drying component 3, a partition frame 4 and a heat conducting plate 5. An exhaust fan 101 is fixedly installed on the top of the shell 1, and two foot pads 102 are fixedly installed on both sides of the bottom of the shell 1. A threaded hole 104 is opened on the right side of the front of the shell 1. The shell 1 can provide an installation position for the internal components. The exhaust fan 101 adopts the DPT07-13H type. After the exhaust fan 101 is powered on, it can exhaust the interior of the shell 1, and then a high vacuum environment can be formed inside the shell 1, so that the boiling point of water can be reduced by the high vacuum environment, so as to quickly evaporate and dry the moisture in the material. The foot pad 102 can support the bottom of the shell 1, so as to ensure the overall stability of the device. The threaded hole 104 can be connected with the locking wheel disc 201 through a threaded structure, so as to facilitate the connection of the box cover 2 with the shell 1, so as to form a sealed environment inside the shell 1, and vacuum dry the material inside the shell 1; The front of the shell 1 is provided with a box cover 2 by means of hinges. The box cover 2 can cooperate with the shell 1 to form a sealed environment inside the shell 1, so as to facilitate the internal air extraction of the shell 1 to form a high vacuum environment, so that the material can be vacuum dried in the high vacuum environment inside the shell 1; A partition frame 4 is fixedly installed inside the shell 1. The partition frame 4 is an H-shaped structure, and the edge of the partition frame 4 is fixedly connected to the inner wall of the shell 1. A plurality of connecting holes 401 are opened inside the partition frame 4. A plurality of electric heating rings 402 are fixedly installed inside the partition frame 4. The partition frame 4 can divide the space inside the shell 1 into a plurality of small partitions, so as to facilitate the partition vacuum drying of the material. The connecting holes 401 can make the air in the plurality of cavities inside the partition frame 4 circulate, so as to facilitate the vacuuming of the shell 1. The electric heating ring 402 can emit heat after being powered on, so as to facilitate the heating of the internal environment of the shell 1, so that the moisture inside and on the surface of the material is vaporized after being heated, so as to achieve the purpose of vacuum drying; A plurality of drying components 3 are fixedly mounted on the back of the housing 1, and the drying components 3 extend out of the back of the housing 1; A plurality of heat conducting plates 5 are fixedly mounted on the inner wall of the shell 1 and the surface of the partition frame 4, and the installation position of the heat conducting plates 5 is in the same horizontal and vertical planes as the drying component 3. A heat conducting groove 502 is provided inside the heat conducting plates 5, and a plurality of heat releasing rods 501 are provided on the surface of the heat conducting plates 5. The heat conducting plates 5 can absorb the heat inside the partition frame 4, thereby increasing their own temperature, and then release the heat through the heat conducting groove 502 and the heat releasing rod 501 inside the heat conducting plates 5, so that the ambient temperature around the drying component 3 rises rapidly, so as to facilitate rapid drying of the material inside the drying component 3.
[0018] Furthermore, the drying component 3 includes a bearing disk 301, which is connected to the back side of the shell 1 through a bearing seat, and the back side of the bearing disk 301 extends to the back side of the shell 1 through a connecting shaft and is equipped with a turntable 302. A mounting seat 303 is fixedly installed on the front side of the bearing disk 301, and a mesh cage 304 is fixedly installed on the front side of the mounting seat 303. The mesh cage 304 is a mesh spherical structure, and a reinforcement ring is fixedly installed inside the mesh cage 304 near the front position. The bearing disk 301 can provide an installation position for the surrounding components and drive the surrounding components to rotate. The turntable 302 can facilitate the staff to rotate the mounting seat 303 and the mesh cage 304 from the outside of the shell 1, thereby driving the material inside the mesh cage 304 to rotate, and can achieve centrifugal drying when rotating at high speed, thereby accelerating the drying of the material.
[0019] Furthermore, an exhaust pipe 103 is fixedly installed on one side of the exhaust fan 101, and one end of the exhaust pipe 103 is fixedly connected to the top of the shell 1. The exhaust pipe 103 can facilitate the exhaust fan 101 to exhaust air from the inside of the shell 1, thereby reducing the internal air pressure of the shell 1, thereby reducing the boiling point of water inside the shell 1, so as to facilitate vacuum drying of the material inside the shell 1.
[0020] Furthermore, a control box 202 is fixedly installed on the front of the box cover 2, and a locking wheel 201 is installed on the right side of the front of the box cover 2 through a threaded structure, and the back of the locking wheel 201 extends to the inside of the threaded hole 104. The control box 202 can be connected to other electronic components through wires, so as to control multiple electronic components to cooperate with each other to complete the work, so that the device can be automatically operated. The locking wheel 201 can cooperate with the threaded hole 104 to lock one side of the box cover 2 to ensure that a sealed environment is formed between the shell 1 and the box cover 2, thereby facilitating vacuum drying of the material inside the shell 1.
[0021] Furthermore, a current controller 403 is fixedly installed on one side of the electric heating ring 402, and the top of the current controller 403 is fixedly connected to the inner wall of the partition frame 4. The current controller 403 can be connected to an external power supply to energize the electric heating ring 402, and according to the data detected by the temperature sensor 404, the electric power of the electric heating ring 402 is intelligently adjusted, so that a low-pressure and constant temperature environment is formed inside the shell 1, so as to facilitate vacuum and low-temperature drying of the material placed inside the mesh cage 304.
[0022] Furthermore, temperature sensors 404 are fixedly installed on the sides of the partition frame 4. The temperature sensor 404 is a PT100 type. The temperature sensor 404 can continuously monitor the temperature inside the shell 1, thereby feeding back the temperature data to the control box 202, so that the control box 202 can control the electric heating ring 402 to achieve a constant temperature environment inside the shell 1.
[0023] Working principle: After the device is assembled and checked to confirm that it is correct, the material to be dried is evenly placed inside the mesh cage 304, and the temperature inside the shell 1 is continuously monitored by the temperature sensor 404. The inside of the shell 1 is evacuated to a near vacuum through the exhaust fan 101, so that a low-pressure constant temperature environment is formed inside the shell 1. The electric current controller 403 releases current to the electric heating ring 402, so that the electric heating ring 402 generates heat to increase the ambient temperature inside the shell 1. At the same time, the turntable 302 is rotated according to the use requirements, so that the mesh cage 304 drives the material inside to rotate, so that the moisture inside and on the surface of the material is vaporized and sucked out of the shell 1 by the exhaust fan 101 to achieve vacuum drying of the material.
