Description

Technical Field

[0001] The invention relates to the technical field of ferric phosphate preparation, and in particular to a pressure shower washing device for preparing anhydrous ferric phosphate. Background Art

[0002] At present, lithium iron phosphate electrode materials have entered the stage of rapid industrial development and application promotion. Power and energy storage batteries made of lithium iron phosphate as the positive electrode have also shown good safety and cycle performance, and their application scale is gradually expanding. However, future energy needs have put forward higher energy density requirements for lithium iron phosphate power and energy storage batteries. As a precursor of lithium iron phosphate, the physical and chemical indicators and morphology of iron phosphate are closely related to the compaction density of lithium iron phosphate batteries. High-compacted anhydrous iron phosphate usually refers to iron phosphate materials with high density characteristics, which are mainly used to manufacture positive electrode materials for lithium-ion batteries, especially lithium iron phosphate batteries. By increasing the compaction density, this material can encapsulate more active substances in a unit volume, thereby improving the energy density of the battery, extending the driving range or reducing the battery volume.

[0003] The iron phosphate precipitate produced during the preparation of anhydrous iron phosphate first needs to be separated from the solid and liquid through a filter press operation. A filter press is usually used to force the suspension to pass through the filter medium under a certain pressure, leaving solid iron phosphate deposited on the filter cloth to form a filter cake. Once the filter cake is formed, the next step is a rinsing step. An appropriate amount of water or other suitable solvent is used to evenly spray or flow the filter cake surface to dissolve and wash away the soluble impurities and remaining reaction reagents on the surface and inside of the filter cake. The plate and frame filter press equipment is widely used in the above links. The plate and frame filter press is a typical intermittent operation process, which means that the filtering, washing and unloading of the material must be carried out in stages, which directly leads to low production efficiency. From filtration to washing to replacing the filter plate, the entire process involves multiple manual or semi-automatic operation steps, which not only increases labor costs, but may also cause operational errors and affect product consistency and stability.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a pressure shower washing device for preparing anhydrous ferric phosphate includes a horizontal conveying frame 1, a circulating guide rail 101 is arranged around the middle of the horizontal conveying frame 1, and also includes:

[0037] Unit filter cartridge 2, multiple unit filter cartridges 2 are evenly arranged in sliding connection around the outside of the circulation guide rail 101, a circulation traction chain 104 is arranged around the middle of the circulation guide rail 101, and the circulation traction chain 104 drives all unit filter cartridges 2 to move synchronously along the circulation guide rail 101, a filter support plate 201 is horizontally fixedly arranged at the center of the unit filter cartridge 2, a plurality of filter openings 202 are evenly distributed in the middle of the filter support plate 201, and an elastic filter cloth 301 is installed above the filter support plate 201;

[0038] A horizontal support frame 107 is horizontally connected and arranged above the horizontal conveying frame 1. A filtering conveying mechanism 4, a plurality of raw material filter pressing mechanisms 5 and a plurality of raw material washing mechanisms 6 are evenly and continuously arranged in the middle of the horizontal support frame 107 in the horizontal direction. A plurality of raw material filter pressing mechanisms 5 and raw material washing mechanisms 6 are alternately arranged, and the spacing between adjacent mechanisms is the same as the spacing between adjacent unit filter cartridges 2.

[0039] The filter conveying mechanism 4 includes a raw material conveying pipe 401. When the unit filter cartridge 2 moves to the position directly below the raw material conveying pipe 401, the raw material conveying pipe 401 conveys the raw material liquid to the unit filter cartridge 2 to be filtered through the elastic filter cloth 301.

[0040] The raw material filter pressing mechanism 5 includes a horizontal filter pressing plate 502, and a hydraulic telescopic rod 501 is connected to the top of the horizontal filter pressing plate 502. When the unit filter cartridge 2 moves to the bottom of the horizontal filter pressing plate 502, the hydraulic telescopic rod 501 drives the horizontal filter pressing plate 502 to move downward to apply pressure to the raw material to squeeze out excess liquid therein;

[0041] The raw material washing mechanism 6 includes a washing tray 601 , and a plurality of washing nozzles 603 are evenly arranged on the bottom surface of the washing tray 601 . When the unit filter cartridge 2 moves to the bottom of the washing tray 601 , the washing tray 601 evenly sprays washing liquid through the washing nozzles 603 to wash the filtered raw material above the elastic filter cloth 301 .

[0042] In this embodiment, the device is provided with a plurality of independent unit filter cartridges 2, each of which is provided with an elastic filter cloth 301, and the circulating traction chain 104 drives all the unit filter cartridges 2 to move synchronously and cyclically along the circulating guide rail 101, so that the plurality of unit filter cartridges 2 can synchronously move cyclically along the circulating guide rail 101 and pass through each mechanism in turn. When the unit filter cartridge 2 moves to the position directly below the raw material conveying pipe 401 of the filter conveying mechanism 4, the pretreated iron phosphate raw material is conveyed through the raw material conveying pipe 401 to release the raw material liquid into the filter cartridge. At this time, the elastic filter cloth 301 in the unit filter cartridge 2 is used as a filter medium to preliminarily separate the raw material. The solid and liquid in the material, and the filtering and conveying mechanism 4 also includes a filtering and recovering cylinder, which is arranged below the upper horizontal conveying guide rail 102. When the unit filtering cylinder 2 moves to the bottom of the raw material conveying pipe 401, it is simultaneously located above the filtering and recovering cylinder, and the filtered liquid naturally falls into the filtering and recovering cylinder for recovery. After completing the preliminary filtering and separation, the unit filtering cylinder 2 continues to move along the circulating guide rail 101 to reach the bottom of the raw material filter pressing mechanism 5. The upper and lower ends of the hydraulic telescopic rod 501 are respectively connected to the top surface of the horizontal support frame 107 and the horizontal filter pressing plate 502, and the hydraulic telescopic rod 501 is evenly surrounded by a plurality of , so as to apply pressure evenly. At this time, the upper horizontal filter press plate 502 is driven by the hydraulic telescopic rod 501 to slowly move downward, applying uniform and controllable pressure to the raw materials on the filter cloth, effectively squeezing out excess water or solvent in the raw materials, and improving the solid-liquid separation efficiency. Then the unit filter cartridge 2 is moved to the bottom of the washing tray 601, and the multiple evenly distributed washing nozzles 603 configured on the bottom surface of the washing tray 601 are started to spray out the prepared washing liquid. These washing liquids accurately cover the elastic filter cloth 301, effectively dissolve and remove residual impurities attached to the surface of solid particles, and further improve the purity of the product, so that the unit filter cartridge 2 can complete a process. It can immediately transfer to the next process without interrupting production for equipment reconfiguration or material transfer. This continuous operation mode covers the entire process from raw material transportation and filtration, filter pressing and dehydration, and spray cleaning, realizing a fully continuous automated process from raw material filtration, filter pressing to washing. Compared with the intermittent operation of traditional plate and frame filter press equipment, it greatly shortens the production cycle, improves production efficiency, and meets the needs of large-scale continuous production. The continuous production process ensures the continuity and consistency of operations in each link, avoids quality fluctuations caused by manual intervention or equipment restart, and effectively improves the purity of the finished ferric phosphate product and the stability between batches.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, preferably, the left and right ends of the horizontal conveying frame 1 of the device are connected with conveying gears 105, the conveying gears 105 are meshed with the circulating traction chain 104, the axial end of the conveying gear 105 is connected with a conveying motor 106, the upper and lower sides of the circulating guide rail 101 are respectively provided with horizontal conveying rails 102, the left and right ends of the circulating guide rail 101 are respectively provided with semicircular conveying rails 103, the two ends of the horizontal conveying rails 102 on the upper and lower sides are connected to each other through the semicircular conveying rails 103, and a discharge collection funnel 108 is provided on the rear side directly below the circulating guide rail 101. When the unit filter cartridge 2 runs to the left and right ends of the circulating guide rail 101, they The filter cartridge 2 will enter the semicircular conveying guide rail 103 in turn. This design allows the unit filter cartridge 2 to be naturally turned over in the process of transitioning from the upper horizontal conveying guide rail 102 to the lower horizontal conveying guide rail 102. During the turning process, the solid materials previously attached to the elastic filter cloth 301 naturally fall off due to gravity and fall into the unloading collection funnel 108 arranged below. The unloading collection funnel 108 is specially designed to receive and temporarily store the solid materials that fall off from the unit filter cartridge 2. The horizontal conveyor belt 109 arranged at the bottom of the funnel is immediately started to smoothly and continuously convey the collected materials to other subsequent processing links, and the center of the elastic filter cloth 301 is fixedly connected with a The center traction rod 302 and the center sleeve 203 are arranged at the center of the filter support plate 201.

The center traction rod 302 is made of ferromagnetic material. When the unit filter cartridge 2 is turned over for unloading, a high-frequency alternating current is passed through the vibration coil 204 to generate a rapidly changing magnetic field. Since the center traction rod 302 is made of ferromagnetic material, when it is nested inside the center sleeve 203 and exposed to the alternating magnetic field generated by the vibration coil 204, it will be affected by the electromagnetic force, thereby moving up and down along the center sleeve 203. The high-frequency micro-vibration of the central traction rod 302 is transmitted to the elastic filter cloth 301 through the physical connection, so that the surface of the filter cloth and the internal fibers vibrate rapidly. This vibration effect can effectively shake off the solid particles and fine impurities accumulated on the filter cloth, reduce blockage, and maintain the filtering efficiency of the filter cloth. The size and frequency of the alternating current introduced can be adjusted according to actual production needs to adjust the vibration frequency and intensity, so as to achieve precise control of the cleanliness degree and filtering efficiency of the filter cloth. In the continuous production process, the automated vibration cleaning mechanism significantly reduces the need for manual intervention and reduces maintenance costs, while ensuring the continuity of the production process and the stability of product quality.

When the filter cloth needs to be replaced, the unit filter cylinder 2 moves to the top of the filter cloth replacement mechanism 7. The unit filter cartridge 2 first moves to the top of the recycling storage rack 702, and then the unlocking electromagnet 207 is energized to attract the elastic locking pin 206 of the magnetic material to slide backward and disengage the locking annular groove 303 to unlock the filter cloth fixing ring 3. The filter cloth fixing ring 3 naturally falls downward under the action of gravity and fits into the recycling storage rack 702 to perform the piston, completing the removal of the filter cloth fixing ring 3. Then the unit filter cartridge 2 continues to translate and moves to the top of the feeding storage rack 703, and the screw motor 707 is driven by the lifting screw 706 and the lifting screw sleeve 705. The lifting support plate 704 can be driven to move upward, and the multiple filter cloth fixing rings 3 stacked thereon can be driven to move synchronously, so that the top filter cloth fixing ring 3 is embedded in the unit filter cylinder 2, and then the unlocking electromagnet 207 loses power and the elastic locking pin 206 moves forward and embeds into the locking annular groove 303 to lock the filter cloth fixing ring 3, thereby completing the automatic replacement of the filter cloth fixing ring 3 and the elastic filter cloth 301, simplifying the operating procedures for filter cloth maintenance and replacement, shortening the equipment downtime, and being conducive to improving the overall production efficiency and maintenance convenience of the equipment.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, preferably, a C-type detection frame 8 is also connected to the top of the horizontal support frame 701 of the device, and the C-type detection frame 8 is located in front of the recovery storage frame 702 and the loading storage frame 703. When the unit filter cartridge 2 moves, it will pass through the C-type detection frame 8, the recovery storage frame 702 and the loading storage frame 703 in sequence. An interlocking detection groove 801 is provided in the middle of the C-type detection frame 8. When the unit filter cartridge 2 moves to the C-type detection frame 8, the unit filter cartridge 2 is located in the middle of the interlocking detection groove 801, and the upper and lower sides of the interlocking detection groove 801 are respectively provided with an upper detection plate 802 and an upper detection plate 803. The lower plate 805 is provided with a plurality of detection delivery pipes 803 evenly distributed in the middle of the detection upper plate 802, a constant pressure valve 804 is provided in the middle of the detection delivery pipe 803, and a plurality of recovery funnels 806 are evenly distributed in the middle of the detection lower plate 805, the recovery funnels 806 are provided one by one with the detection delivery pipes 803, the lower end of the recovery funnel 806 is connected with a detection recovery pipe 807, and a flow meter 808 is provided in the middle of the detection recovery pipe 807, so that when the elastic filter cloth 301 is located between the detection upper plate 802 and the detection lower plate 805, the plurality of detection delivery pipes 806 are evenly distributed in the middle of the detection lower plate 805, and the recovery funnels 806 are provided one by one with the detection delivery pipes 803, and the lower end of the recovery funnel 806 is connected with a detection recovery pipe 807, and a flow meter 808 is provided in the middle of the detection recovery pipe 807, so that when the elastic filter cloth 301 is located between the detection upper plate 802 and the detection lower plate 805, the plurality of detection delivery pipes 806 are provided with a constant pressure valve 804, and the plurality of recovery funnel ... Under the control of the constant pressure valve 804, 803 uniformly conveys constant pressure water flow downward to the surface of the elastic filter cloth 301, which can not only clean the filter cloth, but also ensure the consistency of the test conditions by the constant pressure water flow design. Then the water flow passing through the filter cloth is collected to the detection recovery pipe 807 and monitored in real time by the flow meter 808. The data recorded by the flow meter 808 directly reflects the filtration efficiency of the filter cloth. Any abnormal change in flow rate may indicate that the filter cloth is blocked or damaged. By collecting and analyzing the data of the flow meter 808 and comparing it with the standard value or historical data, the overall filtration performance of the filter cloth and whether there are local problems can be quickly determined, and targeted maintenance or replacement of the filter cloth can be achieved to ensure the continuity of the production process and product quality. Through real-time monitoring of the filter cloth status, the cleaning and replacement cycle of the filter cloth can be reasonably arranged to avoid waste of resources caused by excessive maintenance, while ensuring production efficiency and product quality. At the same time, the data collected by the flow meter 808 provides a scientific basis for the optimization of the production process, which is helpful to further analyze the efficiency of the filter cloth, guide the selection of filter cloth materials and the adjustment of production parameters, continuously optimize the production process, and improve the overall operational efficiency.

[0050] When in use, first connect the corresponding pipelines of the device, and then the conveying motor 106 drives the circulating traction chain 104 to move through the conveying gear 105, and the circulating traction chain 104 drives all the unit filter cartridges 2 to move synchronously and cyclically along the circulating guide rail 101. When the unit filter cartridge 2 moves to the bottom of the raw material conveying pipe 401 of the filter conveying mechanism 4, the pretreated iron phosphate raw material is conveyed through the raw material conveying pipe 401, and the raw material liquid is introduced into the central conveying pipe 404 and continues to flow downward to the annular distribution pipe 405. The annular distribution pipe 405 can drive all the horizontal distribution pipes 406 connected to it to rotate synchronously. When the central conveying pipe 404 drives all the horizontal distribution pipes 406 to rotate through the annular distribution pipe 405, the conveying opening 407 is synchronously and evenly The raw material liquid is evenly sprayed onto the elastic filter cloth 301 located below. At this time, the elastic filter cloth 301 in the unit filter cylinder 2 is used as a filter medium to preliminarily separate the solid and liquid in the raw material. The filtered liquid naturally falls into the recovery conveying cylinder 606 for recovery. After completing the preliminary filtration and separation, the unit filter cylinder 2 continues to move along the circulation guide rail 101 to reach the bottom of the raw material filter press mechanism 5. At this time, the upper horizontal filter press plate 502 is driven by the hydraulic telescopic rod 501 to slowly move downward, applying uniform and controllable pressure to the raw material on the filter cloth, effectively squeezing out excess water or solvent in the raw material. At the same time, the hydraulic drive rod 507 drives the pressure piston 506 to slide along the liquid storage sleeve 505 to press the pressure-conducting liquid into the elastic water storage sleeve 505 through the connecting conveying pipe 504. The capsule 503 is expanded to apply uniform and strong pressure to the elastic filter cloth 301 located below, effectively squeezing the material on the filter cloth and accelerating the discharge of excess liquid. Then the unit filter cartridge 2 is moved to the bottom of the washing tray 601, and the multiple uniformly distributed washing nozzles 603 configured on the bottom surface of the washing tray 601 are started to spray out the prepared washing liquid. These washing liquids accurately cover the elastic filter cloth 301, effectively dissolve and remove the residual impurities attached to the surface of the solid particles, and further improve the purity of the product. Then the unit filter cartridge 2 is naturally turned over in the process of transitioning from the upper horizontal conveying guide rail 102 to the lower horizontal conveying guide rail 102. During the turning process, the solid material previously attached to the elastic filter cloth 301 naturally falls off due to gravity and falls into the bottom set In the unloading collection funnel 108, the horizontal conveyor belt 109 arranged at the bottom of the funnel is started to smoothly and continuously convey the collected materials to other subsequent processing links. When the unit filter cartridge 2 is turned over for unloading, a high-frequency alternating current is passed into the vibration coil 204 to generate a rapidly changing magnetic field. The central traction rod 302 performs high-frequency micro-vibration along the upper and lower directions of the central sleeve 203. The high-frequency vibration of the central traction rod 302 is transmitted to the elastic filter cloth 301 through a physical connection, so that the surface and internal fibers of the filter cloth vibrate rapidly, effectively shaking off the solid particles and fine impurities accumulated on the filter cloth, reducing blockage and maintaining the filtering efficiency of the filter cloth. Then the unit filter cartridge 2 is further moved to the filter cloth replacement mechanism 7, so that the unit filter cartridge 2 is located in the middle of the embedded detection slot 801.When the elastic filter cloth 301 is located between the detection upper plate 802 and the detection lower plate 805, multiple detection delivery pipes 803, under the control of the constant pressure valve 804, uniformly deliver water with constant pressure downward to the surface of the elastic filter cloth 301, and then the water flowing through the filter cloth is collected to the detection recovery pipe 807 and monitored in real time by the flow meter 808. The data recorded by the flow meter 808 directly reflects the filtering efficiency of the filter cloth. Any abnormal change in flow may indicate that the filter cloth is blocked or damaged. By collecting and analyzing the data of the flow meter 808 and comparing it with the standard value or historical data, the overall filtering performance of the filter cloth and whether there are local problems can be quickly determined, so as to achieve targeted maintenance or replacement of the filter cloth. After the detection is completed, the filter cloth replacement mechanism 7 is reset, and the unit filter cartridge 2 continues to move along the circulation guide rail 101 and circulates to the bottom of the filter delivery mechanism 4 to carry out the next working cycle.

[0051] The pressure shower washing device for preparing anhydrous ferric phosphate provided by the present invention is provided with a plurality of independent unit filter cartridges 2, each of which is provided with an elastic filter cloth 301, and the plurality of unit filter cartridges 2 can be synchronously moved in a cycle along the circulation guide rail 101 and pass through various mechanisms in sequence. The circulation guide rail 101 enables the unit filter cartridges 2 to be immediately transferred to the next process after completing one process, without interrupting production for equipment reconfiguration or material transfer. This continuous operation mode covers the entire process from raw material conveying and filtration, pressure filtration dehydration, and spray cleaning, thereby realizing a fully continuous and automated process from raw material filtration, pressure filtration to washing. Compared with the intermittent operation of traditional plate and frame filter press equipment, it greatly shortens the production cycle, improves production efficiency, meets the needs of large-scale continuous production, and the continuous production process ensures the continuity and consistency of operations in each link, avoids quality fluctuations caused by manual intervention or equipment restart, and effectively improves the purity of the finished ferric phosphate product and the stability between batches.
