Technical Field

The invention relates to the technical field of water pollution treatment, in particular to a packaging assembly of a flat ceramic membrane for filtration.

Background

The membrane filtration is a filtration means with high separation efficiency and excellent product water quality, and the separation object can cover the separation between millimeter particles, micron particles, even nano particles and ions. The flat-plate hollow ceramic membrane is a new army in the membrane filtration industry, in the filtration process, pollutants in a solvent, such as suspended particles, colloidal particles, bacteria and the like, are intercepted on the outer surface by a membrane layer, solvent molecules penetrate through the membrane layer, and water is produced through a hollow flow channel in the membrane.

At present, due to the limitation of industrial production and development, the produced water in the hollow runner is generally collected in a water collecting tank mode. This water catch bowl is mostly single-chip or multi-disc package assembly, and in order to guarantee the space separation of purifying feed liquid and external feed liquid of treating in the diaphragm, generally all adopt the form of casting glue to seal the diaphragm. For example, patent (publication No. CN 105709603B) discloses a glue-pouring sealing process for a large-size flat ceramic membrane filter element, which includes steps of firstly processing a section of a large-size flat ceramic membrane body by a precision cutting machine or a grinding machine, then performing glue-filling sealing on the large-size flat ceramic membrane and a water collecting tank by manual insertion and glue-pouring of a glue-pouring machine, and finally performing drying and curing to obtain the large-size flat ceramic membrane filter element.

However, the flat ceramic film is generally made of inorganic oxide material, the encapsulation sealant usually adopts other materials, such as a sealing sealant and an inorganic adhesive, and the external water collecting tank usually adopts another material, such as an aluminum plate. In the casting process, the operation is usually carried out at room temperature or constant temperature in order to meet the requirement of adhesive sealing. The temperature conditions for these packaging are significantly different from the actual use temperature conditions of the flat ceramic film. Each material having different physical properties, particularly thermal expansion properties. Therefore, the temperature difference between the use temperature and the casting time is large, expansion limitation or contraction stress can occur between different materials, and the flat ceramic membrane is damaged.

moreover, at present, most of water collecting tanks are designed to be close to the maximum size of the flat ceramic membrane in the designed size as much as possible in order to meet the packaging requirement of the single flat ceramic membrane. And in order to better finish the collection of the filtered clean liquid, the filter is mostly designed into a single water outlet. The size of the single water outlet water flowing channel is usually smaller due to the design requirement of the water collecting tank and is far smaller than the total flow area of the flat ceramic membrane hollow flow channel. Therefore, the water yield of the membrane element with the packaging structure can not reach the water permeability of the membrane surface of the flat ceramic membrane, and the water yield becomes a limiting bottleneck of the membrane element.

The invention has the beneficial effects that:

(1) The invention aims to overcome the defects existing in the prior art when the glue packaging is adopted, and relates to a novel packaging structure which comprises a filtering membrane, a sealing outer plate, a sealing inner plate and a sealing ring. The filtering membrane penetrates through a combination body formed by the sealing outer plate, the sealing inner plate and the sealing ring, the outer surface of the filtering membrane is closely attached and contacted with the inner side of the sealing ring in an expansion deformation mode, and a gap is formed between the outer surface of the filtering membrane and the sealing inner plate. When the filter membrane is fixed by adopting the structure, when the filtering high temperature is higher than the packaging temperature, the sealing outer plate and the sealing inner plate expand, the linear expansion coefficient of the sealing outer plate is smaller than the macroscopic size, and the sealing outer plate still cannot contact with the filter membrane, namely the filter membrane cannot be extruded. The sealing ring has a certain elastic modulus, so that the deformation rate of the sealing ring changes when the sealing outer plate and the sealing inner plate expand, and the extrusion strength under the deformation condition is smaller than the tolerance strength of the filter membrane, so that the filter membrane cannot be damaged.

(2) In the invention, in order to increase the clamping and fixing effect of the sealing ring, the shape of the hollow cavity in the inner plate is designed to form a structure with a wide end and a narrow end, such as a quadrangular frustum pyramid shape. The clamping force is increased by reacting the hollow cavity of the inner plate which gradually shrinks with the sealing ring.

(3) According to the invention, after the filter membrane, the outer sealing plate, the inner sealing plate and the sealing ring form the packaging structure, the end part of the filter membrane leaks outwards and can be directly used as a clear liquid outlet, no overflowing and flow limiting is realized, and the development of the membrane element is not limited.
