Embodiment Construction
[0017] The following will be described in detail in conjunction with the examples, but the embodiments of the present invention are not limited thereto.
[0018] 1. Method
[0019] Such as Figure 1 ~ Figure 3 As shown, a solid-liquid separation device is composed of a filter element 1 and a cylinder 2. The cylinder body 2 is composed of a bottom plate 2-1 and a cylinder wall 2-2. The bottom plate 2-1 has a hole 2-3; the filter element 1 is composed of a buffer layer 1-1, a filter layer 1-2 and a protective layer 1-1 from the inside to the outside. 3 components, the lower end surface of the filter element 1 is convex; the filter element 1 is set in the cylinder 2 and the lower part of the filter element 1 passes through the cylinder 2 through the holes 2-3, the lower part of the filter element 1 is exposed outside the cylinder 2, and the protective layer 1-3 only Covering the part of the filter element 1 located in the cylinder body 2, the lower edge of the permeable mesh pr...

The invention discloses a solid-liquid filtering device, which comprises a filter element and a cylinder body; the cylinder body is composed of a bottom plate and a cylinder wall, and the bottom plate is provided with holes; the filter element is arranged in the cylinder body and the filter element passes through the cylinder body through the holes; the filter element is from inside to outside It is composed of buffer layer, filter layer and protective layer. The lower end surface of the filter element is convex; the filter layer is composed of flexible capillary fiber material, and the buffer layer is composed of elastic hydrophobic material. The object of the present invention is achieved in this way: the material to be filtered by solid and liquid is put into the cylinder, and the liquid flows from the cylinder to the outside of the cylinder through the capillary formed by the flexible capillary fiber material, and the solid matter cannot be transferred to the cylinder through the capillary In vitro, so as to achieve the purpose of solid-liquid separation. Due to the cushioning effect of the elastic hydrophobic material, even when the capillary fiber material absorbs water and swells, it will not cause capillary blockage. The problem that the usual flexible capillary fiber material filter device expands and is easily blocked when encountering water is solved. The invention is an energy-saving solid-liquid separation device. The invention can be used in combination with technologies such as auxiliary pressurization or vacuuming to further improve work efficiency.
Description
technical field [0001] The invention relates to the field of solid-liquid separation, in particular to a solid-liquid filtering device. Background technique [0002] Solid-liquid separation technology, including filtration technology, will be applied in many fields such as mineral processing, papermaking, medicine and health, food, environmental protection, chemical industry, biotechnology and so on. The carrier of the application of filtration and separation technology is the filtration device, and the technical level of the filtration device often affects the efficiency and results of production and research. [0003] The flexible capillary fiber material will swell when it absorbs liquid, and it will cause blockage of the capillary channel when the space is limited. The invention solves this problem by combining the flexible capillary fiber material with the elastic hydrophobic material. [0004] The filter device uses the capillary formed by the capillary fiber material...
