Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a silicon carbide ceramic membrane filtration device with a self-reverse washing cleaning method. Background Technology

[0002] In conventional water treatment projects, such as those involving groundwater, industrial circulating water, and some surface water, pretreatment is required before ultrafiltration systems are used to prevent fouling of the ultrafiltration system by suspended solids, silt, and organic matter. Furthermore, the ultrafiltration system's backwashing function suspends water production when activated. Membrane fouling worsens with prolonged system operation, affecting continuous operation. Additionally, the combined operation of a pre-filter and ultrafiltration system is disadvantageous in terms of investment and potential chain reactions.

[0003] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] According to the self-reverse washing cleaning method of the silicon carbide ceramic membrane filtration device of this utility model, the bottom of the second arc-shaped cavity is provided with several sets of support frames.

[0011] This invention provides a silicon carbide ceramic membrane filtration device with a self-backwashing cleaning method, comprising: a hollow shell with a first arc-shaped cavity at the top and a first circular plate at the connection between the first arc-shaped cavity and the shell; a second arc-shaped cavity at the bottom and a second circular plate at the connection between the second arc-shaped cavity and the shell; several sets of ceramic membranes connected to the first and second circular plates inside the shell; a sealing connector at the top of the first arc-shaped cavity; a motor at the top of the sealing connector; a central shaft penetrating the sealing connector and the interior of the shell at the output end of the motor; a water inlet at the top of the first arc-shaped cavity; a product water outlet on one side of the shell; a drain outlet at the bottom of the shell; and a sealing assembly on the central shaft.

The backwash water is discharged from the drain outlet. This simultaneous water production and backwashing mode continuously produces water while sequentially backwashing each set of ceramic membranes, improving filtration and backwashing efficiency, reducing fouling, and extending the lifespan of the ceramic membranes.

[0022] See Figure 2 and Figure 3 Preferably, the sealing assembly of this utility model includes an upper sealing member 12 and a lower sealing member 13, which are fixedly connected to the central shaft 8 respectively. The upper sealing member 12 and the lower sealing member 13 are located on the same vertical plane, and the ceramic membrane 9 can be sealed and cleaned synchronously through the upper sealing member 12 and the lower sealing member 13 on the same vertical plane.

[0023] See Figure 2 and Figure 3 In addition, the upper plug 12 of this utility model is a horizontal plate and the lower plug 13 is a sewage pipe. The horizontal plate makes it easier to seal the ceramic membrane 9, and the sewage pipe makes it easier to discharge sewage.

[0027] The working principle of this utility model:

[0028] This invention allows for alternating backwashing of each ceramic membrane group 9 while simultaneously producing ultrafiltration water. Several ceramic membrane groups 9 are installed inside the housing 1.

For backwashing a single ceramic membrane group 9, the inlet 10 is closed, the drain 15 is opened, and the upper and lower plugs 12 are rotated to the designated position of the ceramic membrane 9 via the motor 6 and the central shaft 8. At this time, the upper plug 12 blocks the top of the ceramic membrane 9, allowing external pressure backwashing of the ceramic membrane 9 using the water produced by other ceramic membranes 9. The backwash water is discharged from the drain 15. This simultaneous water production and backwashing mode continuously produces water while sequentially backwashing each ceramic membrane group 9, improving filtration and backwashing efficiency, reducing fouling of the ceramic membranes 9 by contaminants, and extending the service life of the ceramic membranes 9.
