Description

Technical Field

[0001] This utility model relates to the field of drying lithium dihydrogen phosphate, and more particularly to a drying device for lithium dihydrogen phosphate. Background Technology

[0002] When lithium dihydrogen phosphate is produced, it contains a certain amount of moisture and needs to be dried. Previously, we used a traditional microwave oven for drying. If this drying process is not intervened, the dried product will clump together and the drying time will be long. Therefore, based on this technical problem, we optimized and designed a drying device for lithium dihydrogen phosphate. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a drying device for lithium dihydrogen phosphate, including a drying outer box, a drying inner box, a turntable, and a material holding tray. The drying inner box is set inside the drying outer box, and the drying inner box and the drying outer box have an opening on the same side. The opening of the drying inner box is embedded in the opening of the drying outer box. A sealing door is hinged at the opening of the drying inner box, and the sealing door is opened and closed by a buckle. A turntable is set in the middle of the bottom of the drying inner box. The turntable is driven to rotate by a motor inside the drying outer box. A material holding tray is placed on top of the turntable. Microwave generators are set on both sides above the drying inner box. A vacuum pump and a pressure relief valve are set on one side of the drying outer box. The vacuum pump and the pressure relief valve are connected to the drying inner box.

[0004] A gap is provided between the outer drying chamber and the inner drying chamber, and a heat dissipation grille is provided on one side of the outer drying chamber.

[0005] A thermocouple and a vacuum gauge are installed above the outer drying chamber. The probes of the thermocouple and the vacuum gauge are inserted into the inner drying chamber. A temperature display is installed on one side of the opening of the inner drying chamber.

[0006] The turntable has three circular limiting slots in a circular array. A circular limiting piece is provided at the corresponding position on the bottom of the material holding tray. The limiting piece is inserted into the limiting slot for installation.

[0007] The material holding tray is equipped with a serrated scraper at a 180-degree angle to the material holding tray. A connecting vertical rod is located in the middle of the serrated scraper. A connecting horizontal rod is located on the side of the drying inner chamber away from the opening. The upper end of the connecting vertical rod is attached to the connecting horizontal rod. Insertion holes are provided on the upper end of the connecting vertical rod and the upper end of the connecting horizontal rod. The two insertion holes are fixed by U-shaped inserts.

[0008] The serrated scrapers on both sides of the connecting vertical rod have serrated teeth arranged in an alternating pattern, and the paths swept by the serrated teeth on both sides are intersecting.

[0009] The beneficial effects of this utility model are as follows: This device uses continuous vacuuming followed by drying via a microwave generator, greatly accelerating the generation and evaporation of water vapor. A vacuum pump continuously extracts water vapor, ensuring high efficiency throughout the drying process. A 180° serrated scraper constantly moves the material to prevent sticking. This device accelerates drying while preventing material adhesion. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figure 1-5 .

[0014] This utility model discloses a drying device for lithium dihydrogen phosphate, including an outer drying chamber 1, an inner drying chamber 2, a turntable 3, and a material holding tray 4. The inner drying chamber is located inside the outer drying chamber, and both the inner and outer drying chambers have an opening on the same side. The opening of the inner drying chamber is embedded in the opening of the outer drying chamber. A sealing door 5 is hinged to the opening of the inner drying chamber and is opened and closed by a latch 6. The turntable 3 is located in the middle of the bottom of the inner drying chamber and is driven to rotate by a motor inside the outer drying chamber. A material holding tray is placed on top of the turntable. Microwave generators 7 are located on both sides of the upper part of the inner drying chamber. A vacuum pump 8 and a pressure relief valve 9 are located on one side of the outer drying chamber, and the vacuum pump and pressure relief valve are connected to the inner drying chamber. By loading the material into the material holding tray 4 and then closing the sealing door 5, the inner drying chamber 2 is sealed. A vacuum is created by the vacuum pump 8, and after completion, the microwave generator is started for drying. The steam generated during drying is then extracted by the vacuum pump 8.

[0015] A gap is provided between the outer drying chamber and the inner drying chamber, and a heat dissipation grille 10 is provided on one side of the outer drying chamber. The gap between the outer drying chamber and the inner drying chamber is vented by a fan to the outside of the heat dissipation grille 10, so that the inside of the inner drying chamber 2 can continuously dissipate heat.

[0016] A thermocouple 11 and a vacuum gauge 12 are installed above the outer drying chamber. The probes of both the thermocouple and the vacuum gauge are inserted into the inner drying chamber. A temperature display 13 is installed on one side of the opening of the inner drying chamber. The thermocouple 11 and the vacuum gauge 12 monitor the temperature and air pressure of the inner drying chamber 2 in real time.

[0017] The turntable has three circular limiting slots 14 arranged in a circular array. A circular limiting piece 15 is positioned at the corresponding location on the bottom of the material container. The limiting piece is inserted into the limiting slot for installation. The material container can be removed to hold material, and after completion, it can be placed back onto the turntable and positioned by inserting it into the circular limiting slot 14.

[0018] The material holding tray is equipped with a serrated scraper 16 forming a 180-degree angle with the material holding tray as the center. A connecting vertical rod 17 is located in the middle of the serrated scraper. A connecting horizontal rod 18 is located on the side of the drying inner chamber away from the opening. The upper end of the connecting vertical rod is attached to the connecting horizontal rod. Insertion holes 19 are provided on the upper ends of the connecting vertical rod and the upper ends of the connecting horizontal rod. The two insertion holes are fixed by U-shaped inserts 20. When material is placed into the material holding tray, the serrated scraper 16 with the connecting vertical rod 17 is inserted into the material holding tray. After the material holding tray is placed in the predetermined position, the connecting vertical rod 17 and the connecting horizontal rod 18 are attached, and the U-shaped inserts 20 are installed to fix it. This allows the material holding tray to rotate while the serrated scraper 16 remains stationary, thus continuously turning the material.

[0019] The serrated scrapers on both sides of the connecting vertical rod have staggered serrations, and the paths swept by the serrations on both sides are intersecting. The serrated scraper on one side scrapes the material, and after rotating 180°, the staggered serrations of the serrated scraper on the other side push the material again, thus continuously pushing the material to prevent it from sticking.

[0020] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
