[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 1 As shown, the intelligent Chinese herbal medicine drying device described in this embodiment includes a drying system and a drum weighing system 3, the drying system is externally provided with a dust removal and dust prevention system 7 and an automatic loading and unloading system, and an automatic control system 8 is installed on the dust removal and dust prevention system 7, and each system is connected by wire or wirelessly;

[0049] The drying system is composed of a bellows system 1 and a drum drying system 2. The bellows system 1 is arranged at the bottom of the drum drying system 2. The drum drying system 2 can be turned over at a fixed time. The bellows system 1 can be lifted up and down. When heating and drying are required, the hot air mesh plate 23 on the drum is turned to the bottom of the drum. The hot air bellows 11 rises and is tightly combined with the drum. The hot air passes through the mesh plate and penetrates the material from the bottom of the material to dry it.

[0050] Specifically, if Figure 2As shown, the drum drying system 2 includes a drum 21, and the drum 21 is installed on a drum bracket 22. Eight supporting rollers are installed at the bottom of the drum bracket 22. The supporting rollers are used to support the drum and assist the drum to rotate 360 ​​degrees, so as to perform uniform drying and mixing. The drum 21 is composed of a 3 / 4 radially arranged drum body + a 1 / 4 mesh plate.

[0051] It should be noted that the drum 21 is also connected to a transmission assembly, which drives the drum to rotate based on the transmission assembly, thereby providing rotational power to the drum. The drum needs to rotate in occasions such as feeding, discharging, mixing, and clearing.

[0052] More specifically, if Figure 3-4 As shown, two small parts of the drum body are cut, and a hot air mesh plate 23 and a breathable mesh plate 24 with mesh holes are installed. The hot air mesh plate 23 and the breathable mesh plate 24 are positioned facing each other. During drying, the hot air mesh plate 23 is rotated to the bottom of the drum, and the hot air is passed through the hot air mesh plate 23 from the bottom of the material by the hot air bellows 11 which is closely matched with the drum 21, and penetrates the material for drying. The generated hot and humid air is discharged to the outside of the drum 21 by the breathable mesh plate 24 located just above the drum 21.

[0053] like Figure 5 As shown, a material knife 25 is installed in the drum 21, and the material knife 25 can play the role of automatic feeding, automatic discharging, and mixing of materials. The material knife 25 is arranged on the inner side of the hot air mesh plate 23. When the drum 21 is cleared and inspected, after the hot air mesh plate 23 is removed, the internal structure of the drum 21 is completely exposed and unobstructed, and the clearing and inspection are simple and convenient.

[0054] like Figure 6 As shown, the bellows system 1 includes a hot air bellows 11, and the hot air bellows 11 is connected to a hot air fan 12 through an air inlet at one end, and the hot air fan 12 is connected to a heat source 13, and the heat source 13 includes steam heating, electric energy heating and air energy heating. The hot air fan 12 conveys hot air to the hot air bellows 11 through an air duct connector 14, and dries the material in the drum through the drum hot air mesh plate 23. The hot air generated by the hot air fan 12 is received, and three circular air outlets 15 are arranged in the hot air bellows 11. The hot air duct is designed for the hot air bellows 11, and the hot air is discharged into the drum through the three air outlets 15. A wind shield 16 and an air equalizing plate 17 are installed at each circular air outlet 15, and wind shields 16 of different designs are installed on different vents to ensure that the air output of each vent is basically equivalent. The wind plate 17 is used to block back a part of the forward wind, so that the hot air in the wind box is more uniform, and the hot air fan 12 is prevented from directly acting on the material to be dried, so that the faster the wind speed and the larger the air volume, the higher the drying efficiency of the material to be dried under the condition of a certain temperature.

[0055] Four roller lifting devices 4 are installed at the bottom of the hot air bellows 11 and can move up and down. When drying is required, the hot air bellows 11 is raised through the roller lifting devices 4 to cooperate with the roller and seal to ensure that the hot air does not leak out. When the roller needs to rotate or other movements, the bellows is lowered; in order to ensure the convenience of clearing the site and prevent collision with the oil cylinder and the overall aesthetic effect, the roller lifting devices 4 for raising and lowering the hot air bellows 11 are designed inside the hot air bellows 11.

[0056] The drying principle of the drying system is as follows: the hot air mesh plate 23 is rotated to the bottom of the drum 21, the hot air blower 11 rises and is tightly connected to the drum 21, and a large amount of hot air is passed through the hot air mesh plate 23 at the bottom of the drum 21 through the hot air blower 11 to penetrate the material for drying. The energy of the hot air is fully absorbed by the material, and at the same time, the humid air is promptly discharged through the mesh holes at the top of the drum 21, so that the air temperature and humidity in the drum can be controlled to ensure that both the temperature and convection factors are met at the same time: since the material that is first exposed to the hot air dries quickly, in order to ensure uniform drying, the drum 21 can mix the material regularly according to the drying process, so as to ensure that the material is evenly heated and the drying uniformity is high.

[0057] The drum weighing system 3 cooperates with the drying system to realize the weighing of the material to be dried in the drum 21 before and after heating, which solves the problem of large deviation in weighing accuracy of dynamic structures using ordinary weighing sensors. The dynamic weighing method can be converted into static weighing with high weighing accuracy.

[0058] Specifically, if Figure 2 As shown, the roller weighing system 3 includes a weighing sensor and a weighing bracket; the weighing bracket is connected to a roller lifting device 4 that drives the roller to move up and down; when the equipment is running, the roller lifting device 4 rises, and the weighing bracket is separated from the weighing sensor as a whole, and the vibration generated when the equipment is running has no effect on the weighing sensor; when the equipment stops running, the roller lifting device 4 drops, and the weighing bracket falls on the weighing sensor as a whole, and the static weighing measurement is not affected by the accuracy. This makes it simpler and more convenient to replace the weighing sensor to a certain extent. Since the weighing sensor is not connected to the roller bracket 22, the roller lifting device 4 rises, and the weighing sensor is in a free state, it is convenient and quick to disassemble and assemble.

[0059] like Figure 7 As shown, the automatic loading and unloading system includes an automatic loading system 5 and an automatic discharging system 6; the automatic loading system 5 transports the material to be dried to the drum drying system 2, and the feeding modes include climbing type, automatic transmission belt type bucket lifting type and creeper type; the feeding modes are configured according to the on-site installation requirements. The automatic discharging system 6 transports the material to be dried from the drum drying system 2 to a specified position, and the feeding modes include climbing type, automatic transmission belt type bucket lifting type and creeper type; the feeding modes are configured according to the on-site installation requirements.

[0060] The automatic loading system 5 is fixedly connected to the drum door, which is composed of an inner door that can rotate with the drum and a fixed outer door, and the outer door is connected and fixed to the frame by a hinge device; when the lower hopper corresponding to the drum 21 is used for drum discharge, the drum 21 turns over to store the material to be dried in the loading basket after drying, and the material is automatically output from the drum 21 and received by the material basket, and is transmitted to the designated storage point through the automatic discharge system 6;

[0061] The dust removal and dust prevention system 7 packages the drying system and the drum weighing system 3 according to safety and aesthetic requirements to ensure that people cannot touch them.

[0062] Automatic control system 8, composed of PLC and industrial computer, includes automatic control, human-computer interaction and data storage, data analysis, data control and production management; intelligent prediction and control of moisture content, one-button start of equipment, no manual intervention required.

[0063] This embodiment realizes the automated and intelligent drying process of Chinese herbal medicines through the coordinated work of the above-mentioned components. The automatic feeding system 5 feeds the materials into the drum, the hot air bellows 11 provides hot air for drying, and the intelligent control system monitors the entire drying process to ensure precise control of temperature and moisture content, and finally the dried materials are output through the automatic discharging system 6. During the whole process, the dust removal system and protective cover ensure the cleanliness and safety of the operating environment, and the weighing system ensures accurate monitoring of the moisture content of the materials.

[0064] Example 2

[0065] like Figure 8 As shown in Example 1, this embodiment provides a method for drying Chinese herbal medicine, comprising the following steps:

[0066] Step 1: Loading through the automatic loading system 5;

[0067] Specifically, the automatic feeding system 5 includes: when processing incoming materials, the incoming material basket is directly placed on the feeding mechanism,

[0068] Step 2: Pour the materials into the drum in baskets. If the materials are piled up too high in the drum and cannot be fed, swing the drum to spread the materials into the drum and continue feeding until the feeding is completed.

[0069] Step 3: Start the drying system and dry and mix the Chinese herbal medicines through the drying system;

[0070] Specifically, the drying system consists of a bellows system 1 and a drum drying system 2, wherein the drum drying system 2 includes a 3 / 4 radially arranged cylinder + a 1 / 4 mesh plate; the hot air mesh plate 23 is turned to the bottom of the drum 21, and the hot air bellows 11 rises and is tightly connected to the drum 21, and a large flow of hot air is passed through the hot air mesh plate 23 at the bottom of the drum 21 through the hot air bellows 11 to penetrate the material for drying, and the energy of the hot air is fully absorbed by the material. At the same time, the humid air is promptly discharged through the mesh holes at the top of the drum, thereby controlling the air temperature and humidity in the drum 21 to ensure that both the temperature and convection factors are met at the same time: since the material that is first exposed to the hot air dries quickly, in order to ensure uniform drying, the drum 21 can mix the material regularly according to the drying process, thereby ensuring that the material is evenly heated and the drying uniformity is high.

[0071] Step 4: After each mixing, the drum support 22 is lowered, weighed, and the moisture content is evaluated in real time; after the moisture content of the medicinal materials is tested to meet the standard, the heat source 13 is turned off, and cold air is directly blown to start cooling the medicinal materials, and the drying process is completed at the same time.

[0072] Step 5: Place the finished product basket at the exit of the drum 21, and the drum 21 turns over to load the materials into the finished product basket. The cooled finished materials are transported to the designated location through the automatic discharging system.

[0073] Specifically, the finished materials are outputted through the automatic unloading system, the finished basket can be placed at the outlet of the drum 21, the drum 21 is turned over and the materials are loaded into the finished basket, or the cooled finished materials are transported to the designated location through the automatic unloading system.

[0074] The drying method provided in this embodiment is automated and intelligentized through an intelligent control system, ensuring the standardization, uniformity and high-quality finished products of the drying process, while reducing energy consumption, maintaining the appearance of the medicinal materials, and adapting to the drying needs of various medicinal materials.
