Description

Technical Field

[0001] The invention relates to the technical field of lithium hexafluorophosphate processing, in particular to a solid-liquid separation device for lithium hexafluorophosphate production. Background Art

[0002] Lithium hexafluorophosphate is the most important component of electrolyte, accounting for about 43% of the total cost of electrolyte. In the fluorine chemical industry, although the traditional products have declined significantly year-on-year, the demand for high-end products has maintained a strong momentum. In particular, the production and sales of lithium hexafluorophosphate continue to maintain a good trend. With the continued expansion of the new energy field in the future, lithium hexafluorophosphate is expected to usher in a continuous explosion.

[0003] For example, a lithium hexafluorophosphate crystal solid-liquid separation and drying device with publication number CN116422029A has an extrusion assembly, and the lithium hexafluorophosphate after preliminary solid-liquid separation in the separation chamber enters the fixed box through the connecting pipe. After the lithium hexafluorophosphate falls onto the filter plate, the electric push rod 1 is turned on, and the electric push rod 1 pushes the extrusion plate to move, and the extrusion plate squeezes the lithium hexafluorophosphate on the filter plate. Then the electric push rod 1 contracts to drive the extrusion plate to move, and then the electric push rod 2 is turned on to push the push plate to move, and the push plate pushes the lithium hexafluorophosphate on the filter plate to move, and the lithium hexafluorophosphate is drained through the drainage plate 2 and enters through the gap. Drying is carried out in a drying chamber. By setting an extrusion component, lithium hexafluorophosphate can be extruded to achieve better solid-liquid separation of lithium hexafluorophosphate and improve the subsequent drying speed of lithium hexafluorophosphate crystals. However, in actual use, if the lithium hexafluorophosphate dropped on the filter plate is extruded by an extrusion plate, mobile water will leak out of the filter plate after the lithium hexafluorophosphate is extruded. The filter plate is not completely closed. During the extrusion process, the lithium hexafluorophosphate may be subjected to the extrusion force and enter the holes on the filter plate, causing blockage of the filter plate and affecting the subsequent extrusion process of the lithium hexafluorophosphate. There are certain defects in use.

[0004] Therefore, we propose a solid-liquid separation device for lithium hexafluorophosphate production to solve the above problems. Summary of the invention

[0023] Compared with the prior art, the invention has the following beneficial effects: the solid-liquid separation device for lithium hexafluorophosphate production is provided with a processing component below one side of the processing box, so that the lithium hexafluorophosphate crystals can be extruded after preliminary separation, and the through holes will not be blocked during the extrusion process, thereby avoiding affecting the passage of water flow, improving the efficiency of drying the lithium hexafluorophosphate crystals, accelerating the solid-liquid separation of the lithium hexafluorophosphate crystals, and improving the work efficiency and practicality; 1. A processing component is set at the lower side of the processing box, and lithium hexafluorophosphate crystals and liquid are added to the interior of the processing box. The driving motor is started to drive the spiral blade to rotate, so that the liquid is discharged through the filter plate and the drain port, so that the lithium hexafluorophosphate crystals can enter the box through the connecting pipe. After the lithium hexafluorophosphate crystals enter the box, they fall on the top of the fixed plate, and the residual moisture therein can leak out through the through hole and be discharged through the water outlet. The first electric push rod is started to extend, so that the extrusion plate can be driven to move, and the extrusion plate can squeeze the lithium hexafluorophosphate crystals to squeeze out the residual moisture therein. The extrusion plate can drive the movable block to move while moving, so that the movable block drives the connecting rod to move, and then the installation rod can be lifted, and the installation rod drives the movable rod to move upward, and the movable rod drives the sliding block to slide in the sliding groove for limiting, and after the movable rod moves upward, it drives the vertical rod on the support table to insert into the through hole on the fixed plate. In the process, the sliding block moves to the top of the sliding groove, the vertical rod is level with the fixed plate, and the water generated by the extrusion plate extruding the lithium hexafluorophosphate crystal can flow out through the gap between the vertical rod and the through hole, so as to prevent the lithium hexafluorophosphate crystal from entering the through hole after being extruded. After extrusion, the moving plate is lifted by the second electric push rod, and the extrusion plate is continued to be moved, so that the extrusion plate can push the extruded lithium hexafluorophosphate crystal into the drying box through the discharge pipe for drying. The movement of the extrusion plate drives the sliding rod to move at the same time. After the sliding rod moves, the movable block slides inside the movable groove, so that the vertical rod is level with the fixed plate, and the extrusion plate will not get stuck when it moves again. The lithium hexafluorophosphate crystal can be extruded through the processing component, and the through hole will not be blocked during the extrusion process, so as to avoid affecting the passage of water flow, thereby improving the efficiency of drying the lithium hexafluorophosphate crystal, accelerating the solid-liquid separation of the lithium hexafluorophosphate crystal, and improving the work efficiency and practicality. 2. The extrusion plate can drive the crossbar to slide on the box body when extruding the lithium hexafluorophosphate crystal. After the extrusion plate moves, the cover plate can be lifted. When the extrusion plate extrudes the lithium hexafluorophosphate crystal, the roller on the fixed block contacts the cover plate and rotates, so that when the lithium hexafluorophosphate crystal is extruded, the roller can abut against the cover plate, so that the cover plate covers the unloading part of the connecting pipe. After the extrusion is completed, the extrusion plate is reset. The cover plate is perpendicular to the horizontal line under the action of gravity, so that the connecting pipe can continue to unload, and the initial separation of lithium hexafluorophosphate does not need to be stopped during the extrusion process, so as to avoid affecting the extrusion process; The driving motor can drive the first bevel gear to rotate while running, and then drive the rotating shaft to rotate on the support frame by meshing the second bevel gear. After the rotating shaft rotates, the rotating rod can drive the column block to rotate in a circle. The column block can drive the movable frame to reciprocate through the sliding connection with the movable frame, thereby driving the reciprocating rod to reciprocate under the inner bottom of the processing box. The reciprocating rod drives two knocking rods to rotate while moving in one direction. The knocking rod can drive the movable sleeve to rotate on the support rod, and the knocking rod slides on the movable sleeve, so that the knocking rod on one side knocks the filter plate, which can dredge the filter plate and avoid clogging of the filter plate. The filter plate can be knocked by the moving assembly to avoid clogging of the filter plate, and the bottom two sides of the filter plate can be knocked intermittently, so that the two knocking rods are not synchronized, so as to avoid knocking the filter plate together and improve the service life of the filter plate.

After the extrusion is completed, the extrusion plate 212 is reset, and the cover plate 222 is vertically moved under the action of gravity. The first bevel gear 301 is driven by the driving motor 106 to rotate, and the second bevel gear 3031 is engaged with the driving motor 106, and the rotating shaft 303 is driven to rotate on the supporting frame 302. After the rotating shaft 303 rotates, the rotating rod 3032 is driven to rotate, and the rotating rod 3032 is driven to drive the column block 306 to rotate in a circle. The column block 306 is connected to the movable frame 305 by sliding, and the movable frame 305 is driven to reciprocate, thereby driving the reciprocating rod 304 to reciprocate at the bottom of the processing box 1. The reciprocating rod 304 drives the two knocking rods 307 to rotate while moving in one direction. The knocking rod 307 can drive the movable sleeve 309 to rotate on the supporting rod 310.The knocking rod 307 slides on the movable sleeve 309, so that the knocking rod 307 on one side knocks the filter plate 108, which can clear the filter plate 108 and prevent the filter plate 108 from being blocked. The filter plate 108 can be knocked by the moving component 3 to prevent the filter plate 108 from being blocked.
