[0015] The drying apparatus for preparing chromium formate provided by this utility model has the following advantages:

[0016] By incorporating a drying structure, the heating element inside the heating seat heats the interior of the main body, thereby drying the chromium formate. To ensure uniform heating of the chromium formate within the main body, a stirring motor is activated, causing the stirring shaft to rotate on the outer wall of the heating chamber. This, in turn, causes the chromium formate to tumble within the main body, thus improving the drying effect of the device.

[0017] By incorporating a sealing structure, the sealing plate is slid into the chute to the side away from the feed inlet during the feeding process, thus facilitating the addition of chromium formate into the main body. During the drying process, it is slid to the top of the feed inlet and positioned by a threaded connection to prevent external oxygen from entering its interior, thereby achieving the purpose of facilitating the sealing of the feed inlet.

[0025] Please see Figures 1-5 The present invention provides a drying device for the preparation of chromium formate, comprising a main body 1 and a feed inlet 2.

[0026] Reference Figures 1-3 As shown, the main body 1 has a feed inlet 2 at its top, and a sealing structure 3 is provided inside the feed inlet 2. The sealing structure 3 includes a groove 301 inside the feed inlet 2, a sealing plate 302 inside the groove 301, a sealing ring 303 on the outside of the sealing plate 302, a fixing plate 304 fixed to the top of the sealing plate 302, and a fastening bolt 305 passing through one side of the top of the fixing plate 304. The sealing plate 302 is slidably connected inside the groove 301. The sealing plate 302 is a rubber sleeve. The fixing plate 304 has an L-shaped design. The bottom side of one side of the fixing plate 304 abuts against one side of the top of the feed inlet 2. The fastening bolt 305 extends into the inside of the feed inlet 2 and is threadedly connected to the feed inlet 2.

[0027] In the preparation of chromium formate, it needs to be dried. To prevent oxidation during drying, inert gas is introduced into the device through the gas filling pipe 4. To prevent excessive oxygen from entering the main body 1 during drying, a sealing structure 3 is provided, allowing the sealing plate 302 to slide inside the groove 301. A rubber sealing ring 303 is provided on its outer wall to enhance the sealing effect. To prevent the sealing plate 302 from shifting away from the top of the feed inlet 2 and affecting the sealing effect, one side of the fixing plate 304 abuts against the top of the feed inlet 2, and the fastening bolt 305 extending through it extends into the feed inlet 2 to form a threaded connection, thus fixing the position of the fixing plate 304 and greatly increasing the practicality of the device.

[0028] Reference Figure 2 , Figure 4 and Figure 5 As shown, an air inlet pipe 4 is provided on one side of the main body 1, and an air inlet valve 5 is installed inside the air inlet pipe 4. A drying structure 6 is installed on one side of the main body 1, and a pressure relief port 7 is provided at the top of the main body 1. The drying structure 6 includes a stirring motor 601 installed on one side of the main body 1 and a heating chamber 602 opened on the inner wall of the main body 1.

A heating seat 605 is provided inside the heating chamber 602, and heating wires 606 are evenly installed inside the heating seat 605. A temperature sensor 607 is installed on the inner wall of the main body 1 inside the heating chamber 602. The stirring shaft 603 extends into the interior of the main body 1. The heating wires 606 are evenly distributed inside the heating seat 605. A microcontroller is externally connected to the temperature sensor 607, and the output terminal of the microcontroller is electrically connected to the input terminal of the heating wires 606.

[0029] During the drying process of chromium formate, water vapor is generated inside, increasing the pressure. A pressure relief port 7 with a one-way valve inside is provided to relieve pressure and prevent oxygen from entering. To improve the drying effect, a drying structure 6 is installed. The stirring motor 601 is started, causing the stirring impeller 604 to rotate inside the main body 1 via the stirring shaft 603, thus stirring the chromium formate inside and making the heating more uniform. A temperature sensor 607 monitors the internal temperature of the main body 1 in real time, and an external microcontroller controls the heating wire 606 to start the heating process. This ensures that the internal temperature of the main body 1 is always within the appropriate range for drying, thereby improving the production efficiency of the device during the drying process.
