Description

Technical Field

[0001] This utility model relates to the technical field of lithium fluoride, and in particular to a lithium fluoride washing and filtration device. Background Technology

[0002] Lithium-ion batteries, with their advantages of high energy density, high power density, long cycle life, low self-discharge, and high performance-price ratio, have become the primary choice for rechargeable power sources in today's portable electronic products. The electrolyte is made by dissolving electrolyte salts in a mixed organic solvent. Inorganic electrolytes include lithium perchlorate (used only in primary lithium-ion batteries), lithium tetrafluoroborate, lithium hexafluoroarsenate, and lithium hexafluorophosphate. Among these, lithium tetrafluoroborate and lithium hexafluorophosphate are the most commonly used, while lithium fluoride is the main raw material for the production of lithium tetrafluoroborate and lithium hexafluorophosphate. Currently, the common method for synthesizing battery-grade lithium fluoride is to directly react hydrofluoric acid with a suspension of lithium carbonate and water (or a lithium bicarbonate solution) to obtain lithium fluoride. The main drawback of this method is that the lithium fluoride slurry exhibits severe agglomeration during drying, which affects the screening process and consequently the production quality of lithium tetrafluoroborate and lithium hexafluorophosphate. Some existing lithium fluoride solid-liquid separation devices require solid-liquid separation of the lithium fluoride slurry during processing because the slurry contains solid particles.

[0003] In the prior art, publication number CN221267369U includes: an outer cylinder, a cover, and a liquid injection pipe. The outer cylinder is used to carry lithium fluoride, thereby performing solid-liquid separation of lithium fluoride. The solid-liquid separation mechanism includes a separation cylinder with a filter screen and separation holes. When lithium fluoride enters the interior of the outer cylinder, it is filtered through the separation holes and the filter screen, thereby achieving solid-liquid separation of lithium fluoride. This lithium fluoride solid-liquid separation device, through the solid-liquid separation mechanism, can perform solid-liquid separation of lithium fluoride slurry, thus facilitating subsequent processing of lithium fluoride slurry. The solid-liquid separation mechanism, through the extrusion mechanism, can extrude the lithium fluoride slurry, thereby accelerating the efficiency of solid-liquid separation of lithium fluoride slurry through extrusion.

[0004] During use, it was found that the above device can achieve solid-liquid separation, but the solid remains in the separation cylinder and needs to be cleaned with other tools, which is not very convenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lithium fluoride washing and filtration device.

[0006] This utility model discloses a lithium fluoride washing and filtering device, comprising a housing, a filter screen, and support legs. The filter screen is located at the front end of the housing, and a set of support legs is located at each of the four corners of the bottom end of the housing. A feed pipe with a valve is located at the rear end of the housing. The device also includes a squeezing assembly and a descrambling assembly. The squeezing assembly is located inside the housing, and the descrambling assembly is located at the left end of the housing. In use, the descrambling assembly seals the left end of the housing. Then, material is injected into the housing through the feed pipe, the valve is closed, and the squeezing assembly is operated to squeeze the material, causing the liquid material to pass through the filter screen and be discharged, while the solid material remains inside the housing. The descrambling assembly then releases the seal on the left end of the housing, and the squeezing assembly is operated to push the solid material remaining inside the housing out of the housing, achieving rapid solid-liquid separation.

[0007] Preferably, the extrusion assembly includes a first hydraulic cylinder, an extrusion plate, guide rods, and a limiting plate. The first hydraulic cylinder is located at the right end of the housing. The left moving end of the first hydraulic cylinder extends into the housing and is connected to one end of the extrusion plate. The extrusion plate is slidably and sealed inside the housing. Multiple guide rods are provided on the extrusion plate, and each guide rod is slidably connected. A limiting plate is provided at the end of each guide rod away from the extrusion plate. When the first hydraulic cylinder is activated, it extends, thereby pressurizing the material inside the housing under the guidance of the multiple guide rods, thus improving the solid-liquid separation efficiency.

[0008] Preferably, the unloading assembly includes a vertical plate, a horizontal plate, a guide bar, a lifting plate, a sealing plate, a second hydraulic cylinder, and a connecting plate. Two sets of vertical plates are installed at the top of the housing. A set of horizontal plates is installed at the outer ends of the two sets of vertical plates and at the front and rear ends of the housing. A guide bar is installed between the two sets of horizontal plates. A lifting plate is slidably installed on each guide bar. One end of each lifting plate is connected to the right end of the sealing plate. A second hydraulic cylinder is installed at the top of the housing. A connecting plate is installed at the top moving end of the second hydraulic cylinder, and the bottom end of the connecting plate is connected to the top of the sealing plate. During solid-liquid separation, the second hydraulic cylinder is shortened, causing the connecting plate to lower the sealing plate under the guidance of the lifting plate and the guide bar. The sealing plate seals the left end of the housing. When it is necessary to discharge the solid material inside the housing, the second hydraulic cylinder is extended, releasing the seal on the left end of the housing. The first hydraulic cylinder is extended, causing the extrusion plate to discharge the solid material inside the housing.

[0009] Preferably, it also includes a U-shaped clamping plate, a shaft pin, a lead screw, and a wing nut. The bottom end of the sealing plate is provided with a U-shaped clamping plate, and the bottom end of the housing is provided with a shaft pin. The lead screw is hinged to the bottom end of the housing through the shaft pin, and the lead screw is threadedly connected to the wing nut. The sealing plate seals the left end of the housing. The operating lead screw enters the inside of the U-shaped clamping plate, and the wing nut is rotated, so that the wing nut is pressed against the U-shaped clamping plate to seal and reinforce the sealing plate.

[0010] Preferably, it also includes a base, with a base provided at the bottom of each set of legs; multiple sets of legs and multiple sets of bases work together to provide stable support for the equipment and improve stability.

[0011] Preferably, it also includes a flow guide channel, which is installed at the front end of the box; liquid materials pass through the filter screen and are guided through the flow guide channel, improving convenience.

[0012] Preferably, the filter screen is made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the unloading component seals the left end of the box, then the material is injected into the box through the feed pipe, the valve is closed, and then the extrusion component is operated to extrude the material, so that the liquid material is discharged through the filter screen and the solid material remains inside the box. Then the unloading component releases the seal on the left end of the box, and the extrusion component is operated to push the solid material remaining inside the box out of the box, thereby realizing rapid solid-liquid separation of the material.
