Description

Technical Field

[0001] This utility model relates to ceramic membrane filtration materials, and more particularly to a multi-dimensional folded ceramic membrane filter material. Background Technology

[0002] Ceramic membrane filter media are asymmetric membranes formed from inorganic ceramic materials through a special process. The walls of ceramic membrane filter media are densely covered with micropores. Under pressure, the feed liquid flows inside or outside the membrane tube. Small molecules permeate through the membrane, while large molecules are retained, thus achieving separation, concentration, purification, and environmental protection. Due to the fine pore size and high specific surface area of ​​ceramic membrane filter media, it can achieve highly efficient filtration. Furthermore, ceramic membrane filter media also possesses high chemical and thermal stability, allowing it to be used in various environments and is not easily corroded or contaminated by substances in the water. It is widely used in environmental water treatment, gas purification, petrochemical catalyst recovery, pharmaceutical fine separation, and new materials, among other fields. However, most existing ceramic membrane filter media are conventionally cylindrical in shape, and the flow holes are all circular straight-through holes. The contact area between water or gas and the filter media is limited, and the contact time is relatively long, resulting in less than ideal filtration effects. Moreover, after prolonged use, the compressive strength of existing ceramic membrane filter media decreases significantly, leading to damage. Utility Model Content

[0003] To address the problems existing in the ceramic membrane filtration technology mentioned above, this utility model proposes a multi-dimensional folded ceramic membrane filter material with a large specific surface area, high compressive strength, and greatly improved filtration effect.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a multi-dimensional folded ceramic membrane filter material, including a body with a direct current through hole inside, a flange matching the shape of the end of the body being sleeved at the bottom end of the body, a number of continuously and smoothly connected outer folded bodies being arranged in a ring on the outer side of the body, forming an outward flow groove between the outer folded bodies, a striped arc head being provided on the outer side of the end of the outer folded body, a number of continuously and smoothly connected inner folded bodies being arranged in a ring at corresponding positions between the inner folded bodies, forming an inner flow groove between the inner folded bodies, and an inwardly inclined striped slope being provided on the inner side of the end of the inner folded body.

[0005] Furthermore, the width of the body gradually decreases from the top to the bottom.

[0006] Furthermore, the bottom end of the body is a sealed end.

[0007] The beneficial effects of this utility model are as follows: 1. Due to the ring-shaped arrangement of multi-dimensional folded outer and inner folded bodies that are smoothly connected to each other, the specific surface area of ​​the ceramic membrane filter material is greatly increased, which is more than five times the filtration area of ​​a filter tube of the same volume. This increases the residence time of the filter medium (water or gas) within the material, and the overall filtration effect of the ceramic membrane filter material is increased by 50%; 2. The multi-dimensional folded structure has higher structural support and increases the compressive strength of the ceramic membrane filter material by more than 3 times. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-4 As shown, the multi-dimensional folded ceramic membrane filter material of this utility model includes a body 1 with a direct current through hole 8 inside. A flange 2, matching the shape of the body's end, is fitted onto the bottom end of the body. The flange is also made of the same raw material as the body. A series of continuously and smoothly connected outer folded bodies 9 are arranged in a ring around the outer side of the body, forming an outward flow groove 4 between the outer folded bodies. A striped arc-shaped head 3 is provided on the outer side of the end of each outer folded body. A series of continuously and smoothly connected inner folded bodies 5 are arranged in a ring around the corresponding positions of the outer folded bodies on the inner side, forming an inner flow groove 7 between the inner folded bodies. An inwardly inclined striped ramp 6 is provided on the inner side of the end of each inner folded body. When the width of the top and bottom ends of the body is the same, the top and bottom views of this utility model are identical. Figure 2 , 4As shown; when the width (aperture) of the body gradually decreases from the top to the bottom, the top of the body ( Figure 1 The upper end of the middle section is the open end, and the bottom end is the open end. Figure 1 When the lower end (of the middle part) is the sealed end, the bottom view of this utility model is as follows: Figure 5 As shown.

[0016] The multi-dimensional folded ceramic membrane filter material described in this utility model can be manufactured using wet or dry methods. The wet method involves using high-purity powders such as alumina, zirconium oxide, titanium oxide, and silicon carbide as raw materials to form a blank, which is then extruded using a specially shaped mold, coated, and sintered. The dry method involves dry pressing or isostatic pressing. This utility model, by annularly folding outer and inner folding bodies on the outer and inner sides of the main body, creates a multi-dimensional folded three-dimensional structure with staggered inner and outer parts. Compared to existing cylindrical ceramic membrane filter tubes of the same volume, this significantly increases the specific surface area of ​​the ceramic membrane filter material. When the filter medium passes through the direct flow holes and flow channels of the ceramic membrane filter material, it has more opportunities to contact the filter membrane on the ceramic membrane filter material body, resulting in more impurities or harmful substances being filtered, and a significant improvement in the overall filtration effect of the ceramic membrane filter material. Furthermore, because the flange, made of the same raw material, is integrally connected to the multi-dimensional folded structure of the main body, the support is higher, resulting in relatively higher compressive strength and a longer service life for the ceramic membrane filter material.

[0017] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to specific embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of protection of the claims of this utility model.
