Description

Technical Field

[0001] This invention belongs to the field of solid-liquid separation and relates to an acid washing and filtration separation device and a nanomaterial separation device. Background Technology

[0002] Solid-liquid separation is a crucial step in the production of nanomaterials. Due to their extremely small particle size and huge specific surface area, nanomaterials present numerous challenges in solid-liquid separation. Pressure filtration, as a highly efficient solid-liquid separation technology, has been widely used in nanomaterial production. Its principle is to apply pressure, forcing the liquid in a suspension to flow through a filter medium, while solid particles are retained on the medium, thus achieving solid-liquid separation. Pressure filtration technology has advantages such as simple operation, high separation efficiency, and wide applicability, and is widely used in various fields such as chemical engineering, pharmaceuticals, food, and environmental protection.

[0003] Washing and filtration are common operations in the production of nanomaterials. For example, ferric phosphate, a raw material for lithium iron phosphate batteries, undergoes a process where semi-finished ferric phosphate is washed with pure water and then filtered once to remove most of the moisture, resulting in a semi-dry product. Subsequently, it undergoes acid washing and conversion, involving the addition of sulfuric acid to transform the yellow semi-finished product into a white product. The acid-washed product is then filtered again to further remove moisture and residual acid, ultimately yielding a dry, pure ferric phosphate product. However, in existing production processes, the need for acid washing and conversion between the two filtration processes, along with multiple transfers of raw materials, not only increases operational complexity but also reduces production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an acid washing and filtration separation device and a nanomaterial separation device, which can quickly perform primary filtration, acid washing and secondary filtration in sequence without the need for additional transfer during the process, thereby reducing the difficulty of operation and improving production efficiency.

[0005] To solve the above technical problems, the present invention provides an acid washing and filter press separation device, including a support frame, a support platform at the upper end of the support frame, vertical track platforms on both sides of the support platform, vertically arranged drive wheels rotatably connected to both ends of each vertical track platform, two drive wheels on the same side cooperating with a racetrack-shaped vertical transmission belt, a first drive motor for driving the drive wheels to rotate is installed on the support frame, multiple connecting slides distributed along the length direction are connected to each vertical transmission belt, two opposite connecting slides on two vertical transmission belts are cooperating with a storage cylinder with open ends, and the inward end of each storage cylinder can be sealed and slidably connected to the upper surface of the support platform;

[0006] Filter press supports are provided on the sides near both ends of the support platform. Each filter press support has a hydraulic telescopic rod installed downward at its upper end, which matches the position of the storage cylinder. Each hydraulic telescopic rod has a connecting plate at its lower telescopic shaft. Each connecting plate is connected to a pressure plate via multiple connecting shafts at its lower end. The outer diameter of each pressure plate is equal to the inner diameter of the storage cylinder. A sliding hole is opened through the middle of each pressure plate. Each sliding hole is slidably connected to a permeation cylinder with a sealed lower end. Each permeation cylinder includes a sliding section at the upper end and a permeation section at the lower end. A limiting ring is provided on the outer wall of each sliding section above the corresponding pressure plate. Several water seepage holes are opened on the side wall of each permeation section. Each permeation section is covered with a filter cloth sleeve. A liquid extraction pipe extending downward into the bottom of each permeation cylinder is connected to the upper end of each filter press support. A suction pump is installed on each filter press support. The inlet end of each suction pump is connected to the upper end of the liquid extraction pipe via a suction hose. The outlet end of each suction pump is connected to a drain pipe.

[0007] A liquid filling rack is provided on one side of the middle part of the support platform. A liquid filling pipe is provided at the upper end of the liquid filling rack, which is matched with the position of the storage cylinder. A solenoid valve is provided on the liquid filling pipe. The upper end of the liquid filling pipe is connected to an injection pipe. An installation cavity is provided at one end of the support platform, and an electric push rod is installed in the installation cavity, facing outward. The telescopic shaft of the electric push rod is connected to a push plate. The outer diameter of the push plate is equal to the inner diameter of the storage cylinder.

[0008] By adopting the above technical solution, the semi-finished nanomaterial mixture is added into the storage cylinder. The storage cylinder slides along the support platform with the vertical transmission belt. When it slides below the first filter press support, the hydraulic telescopic rod extends, pushing the pressure plate and permeation cylinder downwards. First, the permeation cylinder falls to the bottom of the storage cylinder, spreading the internal solution to both sides. Then, the pressure plate continues to move downwards, compressing the mixture. The water in the mixture is squeezed through the filter cloth and flows into the permeation cylinder. At the same time, the suction pump works, using the liquid extraction pipe to drain the liquid from the permeation cylinder. After squeezing out all the water from the permeation cylinder, the hydraulic telescopic rod... The rod shortens, causing the pressure plate and permeation cylinder to reset. The storage cylinder then continues to move forward. When it reaches the liquid addition rack, the solenoid valve opens, adding pickling solution through the liquid addition pipe. It then continues to move forward. After passing the filter press support at the tail end again, the hydraulic telescopic rod extends, compressing the water in the storage cylinder into the permeation cylinder, and the water in the permeation cylinder is then drained by a suction pump. Finally, the storage cylinder moves to the end of the support platform. When the storage cylinder rotates to a horizontal position, the electric push rod extends, causing the pusher plate to extend into the storage cylinder and push out the dried nanomaterial cake inside, allowing the storage cylinder to continue to be used.

[0009] The invention is further configured such that each vertical track platform has a racetrack-shaped vertical circulating slide rail at its edge, each connecting slide bar has a connecting strip that connects to the corresponding storage cylinder around the corresponding vertical circulating slide rail, and the upper end of each connecting slide bar is rotatably connected to a roller that is rollingly connected to the outer surface of the corresponding vertical circulating slide rail.

[0010] The present invention is further configured such that each storage cylinder is provided with a sealing rubber ring for sealing and sliding connection of the upper surface of the support platform at one end.

[0011] The present invention is further configured such that the outer diameter of the sliding section is equal to the inner diameter of the sliding hole, the outer diameter of the permeation section after being covered by the filter cloth sleeve is equal to the inner diameter of the sliding hole, and a support ring is provided at the lower edge of the permeation section.

[0012] The invention is further configured such that each drive wheel is a gear and each vertical transmission belt is a toothed belt with teeth on the inner side.

[0013] The present invention also provides an acid washing and filter press separation device. A stirring frame is provided on one side of the middle of the support platform. A movable platform is provided at the upper end of the stirring frame. A horizontal chain in the shape of a racetrack is movably connected to the movable platform. A second drive motor for driving the horizontal chain is installed inside the stirring frame. A plurality of vertically arranged vertical sliding sleeves distributed along the length direction are connected to the outer side of the horizontal chain. Each vertical sliding sleeve is slidably connected to a vertical sliding shaft. A stirrer is provided at the lower end of each vertical sliding shaft. The vertical sliding sleeves near the support platform are located above the storage cylinder, so that the stirrers can extend into the storage cylinder one by one.

[0014] A circulating track is provided on the outer side of the movable platform. The circulating track smoothly forms a downward translation track on the side near the support platform. Each vertical sliding shaft is provided with a drive sliding shaft slidably connected to the circulating track and the downward translation track below the vertical sliding sleeve. A friction conveyor belt for driving the vertical sliding shaft is vertically movably provided on the side of the stirring frame near the support platform. Both ends of the friction conveyor belt are provided with vertical drive shafts rotatably connected to the stirring frame. A third drive motor for driving the friction conveyor belt is installed on the stirring frame.

[0015] By adopting the above technical solution, the horizontal chain on the movable platform drives the vertical sliding sleeve to move synchronously with the storage cylinder. When it moves to the position of the lower translation track, the agitator extends into the storage cylinder through the connection between the drive sliding shaft and the lower translation track. The friction conveyor belt moves and drives the agitator to rotate through friction, mixing the solid and liquid in the storage cylinder and making it fully transformed. During the process, the agitator moves with the storage cylinder until it extends out of the storage cylinder at the end of the lower translation track. Then the storage cylinder is squeezed and separated.

[0016] The invention is further configured such that the movable platform is rotatably connected to and meshes with sprockets at both ends of the horizontal chain, and the power output shaft of the second drive motor is connected to one of the sprockets.

[0017] The invention is further configured such that the movable platform is connected to a horizontal circulating slide rail located above the horizontal chain and in the shape of a racetrack, and the upper end of each vertical slide sleeve is connected to a sliding connecting hook that is slidably connected to the horizontal circulating slide rail, and each sliding connecting hook is rotatably connected to a roller that is slidably connected to the inner side of the horizontal circulating slide rail.

[0018] The present invention is further configured such that each stirrer includes multiple spiral stirring rods that are circumferentially connected to the lower end of the corresponding vertical sliding shaft.

[0019] The invention is further configured such that the outer surface of the friction conveyor belt is rough, and each vertical slide shaft is provided with rough knurling below the corresponding drive slide shaft to cooperate with the friction conveyor belt.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Firstly, this invention integrates primary filtration, acid washing, and secondary filtration into a single production line, enabling rapid primary filtration, acid washing, and secondary filtration through a continuous flow operation. No additional transfer is required during the process, which reduces operational difficulty and improves production efficiency.

[0022] Secondly, during pickling, the agitator can move with the storage cylinder and rotate and stir at the same time, which enables rapid pickling conversion and shortens the time spent on the support platform, so as to facilitate faster filtration and improve production efficiency.

[0023] Thirdly, the present invention adopts a brand-new pressure filtration method. By first inserting the permeation cylinder into the storage cylinder, the water is squeezed into the permeation cylinder by the pressure plate, which can increase the area of ​​water passing through the filter cloth sleeve and speed up the pressure filtration efficiency.

[0041] Working principle: The semi-finished nanomaterial mixture is added into the storage cylinder 11. The storage cylinder 11 slides along the support platform 2 with the vertical transmission belt 5. When it slides below the first filter press support 13, the hydraulic telescopic rod 14 extends, pushing the pressure plate 17 and the permeation cylinder 18 downward. First, the permeation cylinder 18 falls to the bottom of the storage cylinder 11, spreading the internal solution to both sides. Then, the pressure plate 17 continues to move downward, compressing the mixture. The water in the mixture is squeezed through the filter cloth sleeve 20 and flows into the permeation cylinder 18. At the same time, the suction pump 23 works, using the liquid extraction pipe 22 to drain the liquid in the permeation cylinder 18. After the water in the permeation cylinder 18 is squeezed out, the hydraulic telescopic rod 14 shortens, driving the pressure plate 17 and the permeation cylinder 18 to return to their original positions. Then, the storage cylinder 11 continues to move forward. When it reaches the liquid addition rack 26, the solenoid valve 28 opens, adding pickling solution into the storage cylinder 11 through the liquid addition pipe 27, and then continues to move forward. During this process, the movable platform 33... The horizontal chain 34 drives the vertical sliding sleeve 37 to move synchronously with the storage cylinder 11. When it moves to the position of the lower translation track 44, the drive shaft 45 is connected to the lower translation track 44, allowing the agitator to extend into the storage cylinder 11. The friction conveyor belt 46 moves and drives the agitator to rotate through friction, mixing the solid and liquid in the storage cylinder 11 to achieve full conversion. During this process, the agitator moves with the storage cylinder 11 until it extends out of the storage cylinder 11 at the end of the lower translation track 44. Then, it passes through the filter press bracket 13 at the tail end again, and the hydraulic telescopic rod 14 extends to compress the water in the storage cylinder 11 into the permeation cylinder 18. The water in the permeation cylinder 18 is then drained by the suction pump 23. Finally, the storage cylinder 11 moves to the end of the support platform 2. When the storage cylinder 11 rotates to a horizontal position, the electric push rod 30 extends, allowing the push plate 31 to extend into the storage cylinder 11 and push out the dried nanomaterial cake inside, so that the storage cylinder 11 can continue to be recycled.
