Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a cross-flow filtration device. Background Art

[0002] The cross-flow filter is a device that uses cross-flow filtration to filter. It has a specific structure and working principle, which can effectively achieve multiple filtration and the cleaning and recycling of filter materials to prevent clogging.

[0003] The main structure includes components such as a filter tank, a filter element group, filter media, and water inlet and outlet pipes. A filter element group is provided inside the filter tank, and the filter element group is usually composed of a large filter element and a small filter element. A cylindrical shell is provided outside the small filter element. Filter media is provided between the large filter element and the small filter element inside the filter tank to further filter impurities in the fluid. A water outlet pipe is connected to the top of the cylindrical shell, and a water outlet pipe connected to the water outlet pipe is provided on the top of the filter tank to facilitate cleaning and discharge of sewage. A water inlet pipe is provided at a lower position on the surface of the filter tank to introduce the fluid to be filtered. A sewage pipe and a filter media outlet pipe are connected to the bottom of the filter tank to discharge pollutants and replace the filter media.

[0004] In terms of working principle, the cross-flow filter device adopts a unique vertical cross-flow filtration method, which can clean the filter element online and realize automatic control. Specifically, the fluid to be filtered is introduced into the filter tank through the water inlet pipe. After the filtration of the large filter element and the small filter element, the filter material further intercepts the suspended matter, particles and impurities in the fluid. The cleaning water enters the filter element group through the connection between the cylindrical shell and the outlet pipe, and the filter element is cleaned online. The cleaned water is discharged through the outlet pipe. When the filter material needs to be replaced, it can be discharged and replaced by opening the sewage pipe and the filter material outlet pipe.

[0005] In general, the cross-flow filter has a compact structure, small size, large filtration flux, long service life, low pressure, small footprint, low investment, convenient maintenance, low operating costs, and no need for disassembly and cleaning. At the same time, its unique vertical cross-flow filtration method can effectively prevent blockage and improve filtration efficiency. For more information, it is recommended to consult relevant professionals.

[0006] For example, a Chinese utility model patent (CN216366812U) discloses a ceramic filter with high filtering accuracy, which solves the following problems: some structures are stacked one layer at a time to make each layer of the filter mesh tightly connected to each other. When the metal liquid impacts the filter mesh, the filter layer below filters fine particles, so the holes of the filter mesh become smaller accordingly, which makes the flow rate below smaller. Under the continuous impact of the metal liquid, it cannot be filtered quickly and may even be blocked, so that the liquid always stays in the top filter mesh, causing the filter mesh pressure to increase or even be damaged. The metal liquid contains impurities and gases, which are tightly The densely stacked structure will cause the holes of the filter to be clogged due to gas pressure and impurities, resulting in a decrease in filtering accuracy; the device includes a supporting shell, which is a hollow cylindrical structure, and a first filter is arranged on the upper end of the supporting shell, the first filter includes a filter layer and a first reinforcement layer on one side of the filter layer and a second reinforcement layer on the other side of the filter layer, a gap space is formed between the outer wall of the first filter and the inner wall of the supporting shell, a second filter is arranged at the bottom of the first filter in the supporting shell, the second filter is a microporous honeycomb structure, and the gap space extends to the upper end surface of the second filter. The utility model has high filtering accuracy, is not easy to be clogged, and has a long service life.
