Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation or liquid-liquid separation, and in particular to a high-flux flat ceramic membrane component based on densely placed single-piece detachable membranes. Background Art

[0002] Flat ceramic membranes are mainly used in sewage treatment, seawater desalination and other fields. When the flat plate is used for sewage treatment, its efficiency mainly depends on the structure of the component. Therefore, the component structure is an important component that determines the membrane flux size of the flat ceramic membrane and the filling volume per unit volume.

[0003] Traditional flat ceramic membrane modules are not only bulky, but also have a small filling volume per unit volume, poor space utilization, and the disassembly of the flat ceramic membrane is relatively cumbersome. The main problems of flat ceramic membrane modules at present are:

[0004] (1) The small unit filling volume of the components and the low space utilization rate result in the construction of a larger sewage pool, which increases the cost of using the components.

[0005] (2) When the flat ceramic membrane is damaged, the disassembly of the traditional flat ceramic membrane assembly is rather cumbersome.

[0006] (3) Existing ceramic membrane assemblies all require external aeration pipelines, which not only increases additional costs but also reduces the filling volume of the flat ceramic membrane.

[0007] In response to the above problems, in 2020, Zhang Yuxin and others arranged flat ceramic membranes of different sizes into a circular shape in a utility model patent for a ceramic membrane assembly (authorization announcement number: CN 209952605 U). Although this improved the space utilization of the flat ceramic membrane, the multi-sized flat ceramic membranes increased the number of molds during production, greatly increasing the cost of the production process.

[0008] In order to solve the problem of assembling flat ceramic membranes of different sizes, Su Xinke et al. assembled multiple identical flat ceramic membranes in a utility model drawer-type flat ceramic membrane assembly (authorization announcement number: CN 211487205 U) to form multiple drawer-type wholes. Although the filling amount of the flat ceramic membrane is increased, the formation of the drawer-type whole requires additional components, which invisibly increases the cost of the ceramic membrane assembly. The drawer-type module consists of eight ceramic membranes, which also increases the inconvenience in disassembly.

[0009] In response to the above-mentioned filling volume problem, Liu Min et al., in their utility model patent for an immersed large-flux flat ceramic membrane device (authorization announcement number: CN 210495956 U), placed the flat ceramic membranes adjacent to each other, thereby increasing the filling volume of the flat ceramic membranes. However, they did not consider the ease of disassembly of the flat ceramic membrane assembly, and required additional aeration pipes, which increased the cost of the assembly.

[0010] To sum up: the existing flat ceramic membrane components do not take into account the weight relationship between the ceramic membrane filling volume and disassembly in their design. In order to solve the problems of low filling volume, cumbersome disassembly and the need for additional aeration pipes in the above components, and in comparison with the prior art, this patent proposes a large-flux flat ceramic membrane component based on densely placed single-piece detachable Utility Model Content

[0043] The collecting pipe 1 is connected to the water collecting pipe 2 and sealed. The water outlet of the collecting pipe 1 is connected to a water pump. The water in the middle of the flat ceramic membrane 3 is continuously sucked by the suction force of the water pump to complete the treatment and purification of sewage.

[0044] An alignment plate 9 is provided at the side end of the vertical support frame 7, and a fastening bolt 8 is threadedly installed on the side end of the alignment plate 9. An aeration support plate 11 is welded and installed in the middle of the horizontal square steel 6, and a baffle 13 is threadedly fixed on the side end of the vertical support frame 7; by removing the baffle 13, the flat ceramic membrane 3 can be disassembled in a single piece, and by extracting a single piece, the single-layer flat ceramic membrane 3 can be inserted and pulled in a single piece, wherein the fastening bolt 8 is threadedly installed on the vertical support frame 7, and the aeration support plate 11 is connected to the horizontal square steel 6 by welding, and gas can circulate inside; a plurality of aeration ports 12 are provided at the lower end of the aeration support plate 11, and an air inlet 14 is provided at the side end of the horizontal square steel 6; wherein the air inlet 14 is connected to the air pump.
