[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a microcrystalline cellulose dehydration and drying device, including a drying box 1, which includes a box body and cylindrical bodies with opposite side walls. One side of the cylindrical body has a feed hopper at its upper end, and the other side has a discharge channel at its lower end. Two annular mounting seats 2 are provided, positioned opposite each other on the side walls of the drying box 1, located outside the openings of the two cylindrical bodies. An annular filter cloth 3 is disposed between the two annular mounting seats 2. A conveying assembly 4 is disposed on the drying box 1 for conveying the raw material within the annular filter cloth 3. The conveying assembly 4 is installed between the two cylindrical bodies and supports the inner wall of the annular filter cloth 3. Through the cooperation of the annular filter cloth 3 and the conveying assembly 4, the microcrystalline cellulose is effectively collected and conveyed. The air assembly 5 is located at the bottom of the drying chamber 1 and is used to dry the raw materials in the annular filter cloth 3 with hot air. The air outlet channel 6 is located at the top of the drying chamber 1 and is used to exhaust the humid hot air. There are two sealing covers 7, which are installed at the feed end and the discharge end of the drying chamber 1, respectively. The two sealing covers 7 are located at the top of the feed hopper and the bottom of the discharge channel, respectively. In use, microcrystalline cellulose is added into the annular filter cloth 3 and the sealing covers 7 are closed. The conveying assembly 4 is started to convey the microcrystalline cellulose, and the hot air assembly 5 is started to dry the microcrystalline cellulose with hot air. The humid hot air is discharged from the air outlet channel 6. Through the annular filter cloth 3, the surface-dried microcrystalline cellulose is effectively prevented from being blown into various angles of the drying chamber, thus ensuring the cleanliness of the drying chamber.

[0023] Specifically, the conveying assembly 4 includes a drive motor 4-1 mounted on the drying chamber 1. The drive end of the drive motor 4-1 extends into the drying chamber 1 and is equipped with a rotating rod 4-2. The side wall of the rotating rod 4-2 is provided with several spirally distributed stirring rods 4-3. The ends of the stirring rods 4-3 are collectively provided with a spiral conveying plate 4-4. The contact end of the spiral conveying plate 4-4 with the annular filter cloth 3 is set as a smooth surface. The spiral conveying plate 4-4 is used to support the inner wall of the annular filter cloth. In use, the drive motor 4-1 is started to drive the rotating rod 4-2, stirring rods 4-3 and spiral conveying plate 4-4 to rotate. The rotation of the stirring rods 4-3 stirs the microcrystalline cellulose, effectively improving the drying efficiency of the microcrystalline cellulose. The rotation of the spiral conveying plate 4-4 realizes the conveying of the microcrystalline cellulose.

[0024] Specifically, the spiral conveyor plate 4-4 is provided with several scrapers 4-5, which are located between the two side walls of the spiral conveyor plate 4-4. The scrapers 4-5 are evenly distributed on the spiral conveyor plate 4-4. When the microcrystalline cellulose on the surface is dried, it will be adsorbed onto the inner wall of the annular filter cloth 3 under the action of hot air. The scrapers 4-5 scrape off the microcrystalline cellulose adsorbed on the inner wall of the annular filter cloth 3, ensuring the ventilation of the annular filter cloth 3 and ensuring the effective discharge of humid hot air.

[0025] Specifically, the hot air assembly 5 includes an air chamber 5-1 located inside the drying chamber 1 and below the annular filter cloth 3. The upper surface of the air chamber 5-1 is set as an arc-shaped surface adapted to the annular filter cloth 3. The air inlet of the air chamber 5-1 is connected to a hot air blower 5-2. The air inlet of the air chamber 5-1 and the air outlet of the hot air blower 5-2 are connected through an air duct. Several evenly distributed air nozzles 5-3 are provided on the arc-shaped surface of the air chamber 5-1. By setting the air nozzles 5-3 on the arc-shaped surface of the air chamber 5-1 adapted to the annular filter cloth 3, the drying efficiency of the hot air assembly for microcrystalline cellulose is effectively improved. In use, the hot air blower 5-2 is started to allow hot air to enter the air chamber 5-1, and the hot air is sprayed out through several air nozzles 5-3 to achieve hot air drying of the microcrystalline cellulose in the annular filter cloth 3.

[0026] Specifically, one end of the sealing cover 7 is hinged to the drying chamber 1, and the other end of the sealing cover 7 is snapped to the drying chamber 1. When drying microcrystalline cellulose, the sealing cover 7 at the discharge end of the drying chamber 1 is in a closed state. After opening the sealing cover 7 at the feed end of the drying chamber 1 and adding microcrystalline cellulose raw materials, the sealing cover 7 is closed. By setting sealing covers 7 at both the feed end and the discharge end of the drying chamber 1, it is effectively prevented that the surface-dried microcrystalline cellulose is blown out from the feed end and the discharge end of the drying chamber 1 when the hot air assembly 5 dries the microcrystalline cellulose with hot air. At the same time, by opening the snap between the sealing cover 7 and the drying chamber 1, it is convenient for users to open or close the sealing cover 7. The operation is simple and convenient.

[0027] Working principle: When this utility model is working, firstly, microcrystalline cellulose is added into the drying box 1, and the sealing cover 7 of the feed end and discharge end of the drying box 1 is closed. Then, the conveying component 4 is started to convey the microcrystalline cellulose into the annular filter cloth 3. At the same time, the hot air component 5 is started to dry the microcrystalline cellulose in the annular filter cloth 3 with hot air. Meanwhile, the humid hot air is discharged from the air outlet channel, realizing the dehydration and drying operation of the microcrystalline cellulose.
