Description

Technical Field

[0001] This utility model relates to the field of suspension production technology, specifically a nano-active calcium carbonate suspension filtration device. Background Technology

[0002] Suspensions are multiphase systems in which small, uniformly dispersed solid particles are often opaque or translucent. Due to the scattering of light by the particles, their stability depends on the interaction between the solid and the liquid, as well as between the particles. Surfactants are often added to prevent agglomeration and sedimentation. Nano-activated calcium carbonate suspensions are suspension systems in which nano-sized activated calcium carbonate particles are uniformly dispersed in a liquid medium (such as water or organic solvent), and surfactants are added to improve dispersibility and stability. They have excellent reinforcing properties, dispersibility, and stability.

[0003] In the preparation of nano-activated calcium carbonate suspension, filtration is required to remove impurities, achieve particle classification, enhance suspension stability, and protect downstream equipment. However, due to prolonged use of the filter element, impurities accumulate on it, reducing filtration efficiency and affecting the purity of the filtered suspension. To maintain filtration performance and ensure filtration quality, a nano-activated calcium carbonate suspension filtration device is provided, which eliminates the drawbacks of existing devices.

[0053] The above embodiment discloses a nano-activated calcium carbonate suspension filtration device.

This can prevent impurities from accumulating on the outer wall of the filter element 6, thereby effectively maintaining the filtration performance and ensuring the filtration quality.

[0055] Meanwhile, the first gear 209, driven by the connecting rod 208, drives multiple second gears 2010 to rotate synchronously through meshing. At this time, the drainage fan 204, driven by the second gears 2010 through the transmission rod 206, rotates in the inner cavity of the drain port 8. This can further improve the efficiency of filtration of the suspension by extracting air and suspension in the inner cavity of the filter element 6.
