Double-channel ceramic filtering membrane

Abstract

The invention provides a double-channel ceramic filtering membrane. A main body of the membrane is in a cylindrical shape, the center of a circle is provided with a drainage hole, the periphery of the drainage hole is radially provided with two layers of membrane holes, membranes are coated in the membrane holes, the drainage hole is externally connected with a water outlet pipe, the membrane holes are externally connected with a water inlet pipe, penetrating liquid after being filtered by an inner-layer membrane hole enters the drainage hole under the action of pressure of the water inlet pipe and is recovered by the water outlet pipe, penetrating liquid after being filtered by an outer-layer membrane hole is infiltrated under the action of pressure of the water inlet pipe by the outer wall of the main body of the double-channel ceramic filtering membrane and is also recovered so as to form double channels, and the water inlet pipe and the membrane holes are sealed; moreover, the compactness degree of the water inlet pipe is greater than the compactness degree of the membranes in the membrane holes, and a plurality of grooves are integrally arranged on the outer circumference of the main body of the membrane in an axial direction; and moreover, the width of the grooves is greater than the diameter of the membrane holes. According to the double-channel ceramic filtering membrane, the path of liquid reaching a penetrating side from a material inlet side in the main body of the membrane is shortened, one penetrating side is added for the inner-layer membrane hole which is adjacent to the drainage hole by the drainage hole, the filtration resistance is greatly lowered, and the filtration efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a dual-channel ceramic filter membrane. Background technique [0002] At present, the health of drinking water has received great attention all over the world. In order to remove harmful substances such as bacteria, microorganisms and heavy metals in water, all human beings are doing their best to explore methods, such as high temperature, bleaching and other methods are widely used, but they cannot Thoroughly remove impurities in water; filter cotton, activated carbon, etc. have very limited filtering effects, and cannot filter impurities with small or finer molecular volumes and heavy metals. For this reason, the membrane filtration technology in the prior art can effectively solve this problem, because the membrane filtration needs to apply a huge pressure to the liquid to form a pressure difference to achieve the purpose of small molecules passing through the membran...

[0002] At present, the health of drinking water has received great attention all over the world. In order to remove harmful substances such as bacteria, microorganisms and heavy metals in water, all human beings are doing their best to explore methods, such as high temperature, bleaching and other methods are widely used, but they cannot Thoroughly remove impurities in water; filter cotton, activated carbon, etc. have very limited filtering effects, and cannot filter impurities with small or finer molecular volumes and heavy metals

For this reason, the membrane filtration technology in the prior art can effectively solve this problem, because the membrane filtration needs to apply a huge pressure to the liquid to form a pressure difference to achieve the purpose of small molecules passing through the membrane while the macromolecules are blocked by the membrane. Membrane filtration devices generally have the problems of poor permeability, high filtration resistance, low filtration efficiency and high energy consumption
