[0033] See also Figures 1 to 3In order to better understand the solid-liquid separation device 10 for nickel-iron particle materials of the present application, the solid-liquid separation device 10 for nickel-iron particle materials is further explained below:

[0034] The solid-liquid separation device 10 for nickel-iron granular material according to one embodiment includes a base 100, a driving assembly 200 and a separation mechanism 300. The base 100 is provided with a collecting chamber 110. The driving assembly 200 is fixedly mounted on the base 100. The separation mechanism 300 includes a solid-liquid screening cabin 310 and a centrifugal rotating cabin 320; the solid-liquid screening cabin 310 is located in the collecting cabin 110, and the centrifugal rotating cabin 320 is located in the solid-liquid screening cabin 310; the top of the centrifugal rotating cabin 320 is rotatably connected to the collecting cabin 110, the centrifugal rotating cabin 320 is provided with a material injection port 3201, the bottom end of the centrifugal rotating cabin 320 is connected to the power output end of the driving assembly 200, and the peripheral wall of the centrifugal rotating cabin 320 is provided with a plurality of primary filter holes 3202 connected to the solid-liquid screening cabin 310; the peripheral wall of the solid-liquid screening cabin 310 is provided with a plurality of secondary filter holes 3101 connected to the collecting cabin 110, and the aperture of the secondary filter hole 3101 is smaller than the aperture of the primary filter hole 3202.

[0035] In this embodiment, the liquid raw material containing nickel-iron metal particles is filled into the centrifugal rotating chamber 320 through the injection port 3201, and the driving assembly 200 is started to drive the centrifugal rotating chamber 320 to rotate, so that the centrifugal rotating chamber 320 generates a high-speed centrifugal force, which can throw the nickel-iron solid particles that are not completely dissolved and the liquid raw material into the solid-liquid screening chamber 310 through multiple primary filter holes 3202; wherein, the nickel-iron solid particles that are not completely dissolved and qualified cannot pass through the secondary filter holes 3101, while the liquid raw material doped with the nickel-iron solid particles that are dissolved and qualified can pass through the secondary filter holes 3101 into the collecting chamber 110, thereby achieving efficient separation of the nickel-iron solid particles that are not completely dissolved and the liquid raw material containing qualified nickel-iron solid particles, thereby avoiding the problem of the nickel-iron solid particles violently scratching the inner wall of the transportation pipeline during the subsequent pipeline transportation of the liquid raw material, thereby causing the transportation pipeline to require frequent maintenance.

[0036] like Figures 1 to 3 As shown, in one embodiment, the solid-liquid separation device 10 for nickel-iron particulate material also includes a sealed cabin 400, which is located at the bottom end of the centrifugal rotating cabin 320 and is fixedly connected to the base 100, and the sealed cabin 400 is provided with a first rotating through hole 401; in one embodiment, the drive assembly 200 includes a centrifugal motor 210, which is arranged in the sealed cabin 400, and the power output end of the centrifugal motor 210 is fixedly connected to the bottom end of the centrifugal rotating cabin 320 through the first rotating through hole 401.

[0038] It can be understood that by starting the centrifugal motor 210, the power output end of the centrifugal motor 210 drives the centrifugal rotating cabin 320 to run at a high speed, and reliably generates centrifugal force, so that the qualified nickel-iron solid particles and liquid raw materials that are not completely dissolved can be thrown into the solid-liquid screening cabin 310 through multiple primary filter holes 3202; solid-liquid separation is then performed by the solid-liquid screening cabin 310, that is, the qualified nickel-iron solid particles that are not completely dissolved cannot pass through the secondary filter holes 3101, and fall into the stockpile cabin 3110 by their own weight; the unqualified nickel-iron solid particles in the stockpile cabin 3110 are regularly sucked and transported to the solid collection assembly (not shown) by the solid negative pressure pump 520 to wait for further processing.

[0045] It can be understood that a rotating bearing member 600 is installed at the second rotating through hole 1101. Specifically, the annular rotating portion 3220 of the centrifugal rotating chamber 320 can be rotatably connected to the second rotating through hole 1101 through the rotating bearing member 600. At the same time, a plurality of fixed columns 120 are distributed circumferentially on the outer wall of the collecting chamber 110, thereby enhancing the structural connection strength of the device of the present application, ensuring the balance of the centrifugal rotating chamber 320 during high-speed rotation, and further increasing the structural rationality of the centrifugal rotating chamber 320.
