[0002] Filtration devices for lithium borohydride production refer to specialized filtration equipment used in the synthesis, purification, and refining of lithium borohydride (LiBH4) to separate solid impurities (such as unreacted raw materials, reaction byproducts, and mechanical dust) from the feed liquid, achieving efficient separation of the solid and liquid phases. These devices are also designed to accommodate the chemical properties of lithium borohydride, such as its tendency to hydrolyze, strong reducing properties, and corrosiveness to certain materials.

[0003] Existing filtration devices used in lithium borohydride production typically use scrapers to remove impurities. However, this single-structure impurity removal method is not efficient enough and can easily clog the filter screen, reducing its filtration effect.

[0004] Therefore, it is necessary to propose a filtration device for lithium borohydride production to solve the above problems. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be understood that the terminology used is for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] This utility model provides, for example Figures 1-4 The filtration device for lithium borohydride production shown includes a filter tank 1, a filter groove 11 on the top surface of the filter tank 1, a first rotating shaft 13 rotatably mounted in the middle of the filter groove 11, and multiple frames 14 evenly installed on the outer periphery of the first rotating shaft 13. Filter screens 15 are fixedly connected between the inner walls of the frames 14. During lithium borohydride production, liquid raw materials are added to the filter groove 11 through a pipe on one side of the filter tank 1. The first rotating shaft 13 is rotated, which drives the frames 14 and filter screens 15 to rotate. The filter screens 15 filter the liquid, and the filtered impurities adhere to the side wall of the filter screens 15. The filtered liquid is discharged through a discharge pipe.

[0020] Furthermore, multiple receiving shells 12 are evenly arranged on one side of the filter tank 11. A connecting frame 2 is fixedly connected to the top surface of the filter tank 1 near the receiving shell 12. Multiple air jet frames 21 are fixedly connected to the side wall of the connecting frame 2. Multiple rotating rods 23 are rotatably connected to the side wall of the connecting frame 2. Multiple elastic strips 24 are fixedly connected to the outer periphery of the rotating rods 23. A striking ball 25 is fixedly connected to the end of the elastic strip 24. The striking ball 25 is in movable contact with the side wall of the corresponding filter screen 15. The receiving shell 12 and the frame 14 The filter screens 15 are spaced apart. Inert gas is delivered to the jetting frame 21 through the connecting frame 2. The jetting frame 21 sprays the gas onto one side of the filter screen 15. The gas spray can blow off the impurities adhering to the filter screen 15 and the impurities fall into the receiving shell 12. At the same time as the jetting frame 21 blows the inert gas, the rotating rod 23 rotates synchronously. The rotation of the rotating rod 23 drives the elastic strip 24 and the striking ball 25 to rotate. The striking ball 25 strikes the side wall of the filter screen 15, and the striking can make the stubborn impurities adhering to it fall off.

[0021] It should be noted that both the elastic strip 24 and the striking ball 25 are elastic; the setting of the elastic strip 24 and the striking ball 25 can prevent the impact force generated by the tapping from damaging the filter screen 15.

[0022] It should also be noted that multiple blades 22 are uniformly fixedly connected to the outer periphery of the rotating rod 23, and multiple nozzles 26 are fixedly connected to the bottom surface of the jet frame 21. The nozzles 26 are inclined to one side of the blades 22. The jet frame 21 delivers gas into the nozzles 26. Since the nozzles 26 blow towards the blades 22, the gas blown out by the nozzles 26 drives the blades 22 to rotate, and the blades 22 drive the rotating rod 23 to rotate.

[0023] This invention utilizes multiple structures to remove impurities from the filter screen 15. The scraper 27 can scrape off the impurities adhering to the filter screen 15, while the jet frame 21 uses inert gas to blow away the impurities from the filter screen 15. During the blowing away of impurities, the elastic strip 24 and the striking ball 25 simultaneously strike the side wall of the filter screen 15, effectively removing impurities from the filter screen 15, preventing impurities from clogging the filter screen 15, preventing raw material contamination, and improving the filtration effect of the filter screen 15.

[0024] In this invention, multiple receiving shells 12 and multiple filter screens 15 are spaced apart. A scraper 27 is fixedly connected to one side of the top surface of the receiving shell 12. The scraper 27 is inclined and its top contacts the side wall of the filter screen 15. The waste material adhering to the filter screen 15 is scraped off by the cooperation of the scraper 27 and the filter screen 15 after the filter screen 15 rotates to the top of the receiving shell 12. The scraped waste material falls into the receiving shell 12.

[0025] In this invention, a motor 4 is fixedly connected to one side of the filter tank 1. One end of the first rotating shaft 13 passes through the filter tank 1 and is fixedly connected to the rotating shaft of the motor 4. Two transmission wheels 42 and a transmission belt 41 are provided on the side of the filter tank 1 away from the motor 4. The two transmission wheels 42 are fixedly connected to the end of the second rotating shaft 31 and the end of the first rotating shaft 13, respectively. Both transmission wheels 42 are connected to the transmission belt 41 for transmission. When in use, the motor 4 is turned on, and the motor 4 rotates, driving the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the top transmission wheel 42 to rotate. The top transmission wheel 42 drives the bottom transmission wheel 42 to rotate through the transmission belt 41. The rotation of the bottom transmission wheel 42 drives the second rotating shaft 31 to rotate.

[0026] It should be noted that a conveying shell 3 is fixedly connected to the bottom of one side of the filter tank 1, and the bottoms of multiple receiving shells 12 are all connected to the conveying shell 3. A second rotating shaft 31 is rotatably installed inside the conveying shell 3, and an auger blade 32 is fixedly connected to the outer periphery of the second rotating shaft 31. The auger blade 32 is in contact with the inner wall of the conveying shell 3. After the waste falls into the receiving shell 12, it enters the conveying shell 3 along the receiving shell 12. The rotation of the second rotating shaft 31 drives the auger blade 32 to rotate, and the auger blade 32 moves the waste from the conveying shell 3 to the discharge port. The user collects the waste and processes it uniformly.
