Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and more specifically, to a storage bin for preparing materials for a lithium battery coating material. Background Art

[0002] In the production process of lithium batteries, as an important component, the performance of the coating material directly affects the overall electrochemical performance and service life of the lithium battery. The main function of the traditional storage bin for preparing coating materials is to seal and store raw materials to prevent external impurities from contaminating, but this method cannot fully guarantee the purity of the raw materials. When traditional storage bins store raw materials, it is often impossible to avoid the problems of caking or deterioration of the raw materials caused by excessive humidity during storage, which not only affects the utilization rate of the raw materials but also reduces the performance of the coating material. Secondly, for the coating material, the mixing uniformity of its raw materials is crucial to the quality of the product. However, traditional storage bins cannot achieve automatic mixing of raw materials during storage and require manual intervention or additional equipment to complete the mixing work, which not only increases production costs but also may affect the product performance due to uneven mixing. Therefore, we propose a storage bin for preparing lithium battery coating materials to solve the above problems. Summary of the Utility Model

A drying and dust removal mechanism 6 is installed between the storage bin 1 and the sealing cover 2. An annular sealing block 7 is installed on the lower surface of the sealing cover 2, and the annular sealing block 7 is snap-fitted inside the storage bin 1.

[0023] As Figures 4 to 6 shown, in another embodiment of the present utility model, the drying and dust removal mechanism 6 includes a rotating shaft 601. The rotating shaft 601 is movably installed through the inside of the sealing cover 2, and the lower end of the rotating shaft 601 is movably installed inside the storage bin 1. A plurality of stirring rods 608 are fixedly installed on the outer side of the rod body of the rotating shaft 601 inside the storage bin 1. A motor 607 is installed at the upper end of the sealing cover 2, and the output end of the motor 607 is connected to the upper end of the rotating shaft 601. A sealing frame 602 is installed at the upper end of the sealing cover 2, and the rotating shaft 601 is movably installed through the inside of the sealing frame 602. The upper and lower ends of the rotating shaft 601 close to one side of the sealing frame 602 are respectively provided with sealing grooves 603. The upper and lower ends of the sealing frame 602 are respectively snap-fitted inside the sealing grooves 603. Sealing gaskets are respectively installed between the sealing frame 602 and the sealing grooves 603. A through groove 606 is provided inside the rotating shaft 601 and the stirring rods 608. A plurality of first through holes 604 are provided through the outer side of the rod body of the rotating shaft 601 between the sealing frames 602. The first through holes 604 are connected to the through groove 606. An air inlet pipe 605 is installed through the front end of the inside of the sealing frame 602, and the air inlet pipe 605 is connected to an external hot air blower. A plurality of second through holes 609 are respectively provided through the outer side of the rod body of the stirring rods 608. The second through holes 609 are respectively connected to the through groove 606. Filters are respectively installed inside the second through holes 609. A placement rack 610 is installed on one side of the storage bin 1. A connecting pipe 613 is installed through between the placement rack 610 and the storage bin 1. A second valve 614 is installed inside the connecting pipe 613. An air outlet pipe 612 is installed through the side of the placement rack 610 away from the connecting pipe 613. A filter 611 is installed inside the placement rack 610. The filter 611 is respectively connected to the connecting pipe 613 and the air outlet pipe 612.

[0024] The user opens the first valve 5 inside the feed pipe 3, and then the user can pour the raw materials into the inside of the storage bin 1 through the feed pipe 3. After the raw materials are poured, the user closes the first valve 5 to maintain the sealing performance inside the storage bin 1. Then the user starts the motor 607 and an external hot air blower, so that the motor 607 drives the rotating shaft 601 and the stirring rod 608 to rotate, and the stirring rod 608 mixes and stirs the raw materials. At the same time, the hot air blower blows hot air along the air inlet pipe 605 into the space between the sealing frame 602 and the rotating shaft 601. Then the hot air enters the inside of the through groove 606 along the first through hole 604. Finally, the hot air entering the inside of the through groove 606 blows between the raw materials along the second through hole 609 to dry the raw materials, and at the same time blows the remaining dust on the surface of the raw materials, so that the air drives the water vapor and dust to enter the inside of the filter 611 along the connecting pipe 613. After the filter 611 filters the water vapor and dust inside the air, it can be discharged through the air outlet pipe 612;

[0025] The sealing frame 602 and the sealing groove 603 cooperate with the sealing gasket to seal the space between the sealing frame 602 and the rotating shaft 601, prevent gas leakage, and at the same time assist the rotating shaft 601 to rotate, improving the stability of the rotating shaft 601 during rotation;

[0026] The filter screen inside the second through hole 609 is used to isolate the raw materials to prevent blockage when entering the inside of the through groove 606 through the second through hole 609, thus making it more convenient to mix and dry the raw materials.

[0027] The working principle of this kind of storage bin for preparing lithium battery coating materials:

[0028] When in use, first the user opens the first valve 5 inside the feed pipe 3, and then the user can pour the raw materials into the inside of the storage bin 1 through the feed pipe 3. After the raw materials are poured, the user closes the first valve 5 to maintain the sealing performance inside the storage bin 1. Then the user starts the motor 607 and an external hot air blower, so that the motor 607 drives the rotating shaft 601 and the stirring rod 608 to rotate, and the stirring rod 608 mixes and stirs the raw materials. At the same time, the hot air blower blows hot air along the air inlet pipe 605 into the space between the sealing frame 602 and the rotating shaft 601. Then the hot air enters the inside of the through groove 606 along the first through hole 604. Finally, the hot air entering the inside of the through groove 606 blows between the raw materials along the second through hole 609 to dry the raw materials, and at the same time blows the remaining dust on the surface of the raw materials, so that the air drives the water vapor and dust to enter the inside of the filter 611 along the connecting pipe 613. After the filter 611 filters the water vapor and dust inside the air, it can be discharged through the air outlet pipe 612.

[0029] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
