Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane technology, and specifically to an assembled ceramic membrane module. Background Technology

[0002] Ceramic membranes are asymmetric membranes formed from inorganic ceramic materials through a special process. They are mainly divided into two types: tubular ceramic membranes and flat-sheet ceramic membranes.

[0003] Modular ceramic membrane modules are ceramic membrane filtration systems constructed using a modular design concept. These modules are typically composed of multiple ceramic membrane units, and the number of units can be flexibly increased or decreased as needed to adapt to different processing capacities and space requirements. In a modular ceramic membrane module, each ceramic membrane unit usually consists of one or more ceramic membrane tubes with specific pore sizes, capable of retaining particles or molecules of different sizes according to the required separation precision.

[0004] To ensure good sealing and prevent liquid leakage, existing modular ceramic membrane modules typically employ a combination of sealing methods. Furthermore, the connecting pipes in these modules usually utilize welding, flange connections, or threaded connections. While welding provides a very strong connection, it requires cutting tools for disassembly and can easily damage the pipes and membrane module.

[0005] Therefore, it is necessary to invent a modular ceramic membrane module to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an assembled ceramic membrane module to address the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modular ceramic membrane assembly, comprising a sleeve, wherein a plurality of uniformly distributed tubular ceramic membranes are vertically placed inside the sleeve, the plurality of tubular ceramic membranes are arranged in a ring array, a top cover is installed on the top of the sleeve, and a bottom cover is provided at the bottom of the sleeve.

[0008] A sampling interface is fixedly installed on the outside of one side of the sleeve, an inlet pipe is fixedly installed on the upper side of the other side of the sleeve, and an outlet pipe is fixedly installed on the lower side of the other side of the sleeve. Multiple locking rods are provided between the edges of the top cover and the bottom cover, and the multiple locking rods are located outside the sleeve.

[0009] As a preferred embodiment of this utility model, the top cover and the bottom cover are provided with a plurality of positioning holes, which are arranged in a ring array and correspond to the ends of a plurality of tubular ceramic membranes.

[0010] As a preferred embodiment of this utility model, the top cover has multiple through holes along its edge, and the bottom cover has multiple threaded holes at its upper end along its edge. The number and position of the threaded holes correspond to those of the through holes, and the lower end of the locking rod is threadedly connected to the threaded holes along the edge of the bottom cover.

[0011] As a preferred embodiment of this utility model, limiting rings are fixedly installed on the exterior of both the upper and lower ends of the tubular ceramic membrane. The limiting rings at the upper and lower ends of the tubular ceramic membrane are respectively located at the bottom of the top cover and the top of the bottom cover. The outer diameter of the limiting ring is larger than the diameter of the positioning hole.

[0012] As a preferred embodiment of this utility model, a connecting part is fixedly installed on the upper end of the bottom cover, the connecting part is threadedly connected to the lower outer surface of the sleeve, and a cap is installed on the outside of the front opening of the sampling interface.

[0013] As a preferred embodiment of this utility model, the upper end of the tubular ceramic membrane is inserted into the positioning hole of the top cover, and the lower end of the tubular ceramic membrane is inserted into the positioning hole of the bottom cover.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The top and bottom covers are tightly fixed to both ends of the sleeve by locking rods, and the connection is made by threaded connection. This design can effectively prevent liquid from leaking from the end and side of the component, ensuring the sealing of the entire ceramic membrane component. Multiple tubular ceramic membranes are distributed in a ring array inside the sleeve. Their upper and lower ends are matched with the top and bottom covers by limiting rings. This not only plays a good positioning role for the tubular ceramic membranes, but also further enhances the stability of the internal structure of the component. This ensures that even if subjected to certain pressure or vibration during operation, the relative position between the components can remain stable, reducing the risk of sealing failure caused by component displacement.

[0016] 2. Compared to traditional ceramic membrane modules that use welding or other methods to connect pipes, this module primarily uses threaded connections. This connection method eliminates the need for special welding equipment during installation, simplifying operation and effectively shortening assembly time. When disassembly is required, such as for cleaning, maintenance, or replacement of the tubular ceramic membrane, simply unscrew the locking rod and the connection between the bottom cover and the sleeve to open the top and bottom covers, allowing for the removal or replacement of the tubular ceramic membrane. This avoids the need for cutting tools and the risk of damage associated with welding, significantly reducing disassembly difficulty and the risk of damage to the module. This contributes to lower maintenance costs and improved maintenance efficiency. Attached Figure Description

[0024] 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.

[0025] This utility model provides, for example Figure 1-4The illustrated modular ceramic membrane module includes a sleeve 1, which provides space for internal tubular ceramic membranes 2. Its structural shape ensures that multiple tubular ceramic membranes can be arranged in a ring array, facilitating the formation of stable flow channels within the sleeve 1. This allows the liquid to contact the ceramic membranes uniformly, improving the efficiency and effectiveness of filtration and other treatment processes. Simultaneously, the sleeve 1, as the main frame of the overall structure, withstands internal liquid pressure and external mechanical stresses, providing a fundamental guarantee for the stability of the entire module. Several uniformly distributed tubular ceramic membranes 2 are vertically placed inside the sleeve 1. As the core filtration element, the porous structure of the tubular ceramic membranes 2 allows for the separation, filtration, or concentration of different substances in the liquid based on their pore size. The ingeniously designed limiting rings 14 at the upper and lower ends, through their cooperation with the top cover 3 and bottom cover 4, achieve precise positioning, ensuring the accuracy of the ceramic membrane's position during module assembly and preventing it from shifting or shaking within the sleeve 1. This ensures the stability and operational reliability of the entire module structure. Several tubular ceramic membranes 2 are arranged in a ring array. A top cover 3 is installed on the top of the sleeve 1, and a bottom cover 4 is provided at the bottom of the sleeve 1. The top cover 3 and the bottom cover 4 cooperate with the ends of the tubular ceramic membranes 2 through positioning holes 8, which plays a role in precisely fixing the position of the ceramic membranes, so that the ceramic membranes maintain a stable arrangement within the sleeve 1, which is conducive to the uniform passage of liquid through each ceramic membrane for treatment.

[0026] A sampling interface 10 is fixedly installed on one side of the sleeve 1, an inlet pipe 12 is fixedly installed on the upper side of the other side of the sleeve 1, and an outlet pipe 13 is fixedly installed on the lower side of the other side of the sleeve 1. Multiple locking rods 5 are provided between the edges of the top cover 3 and the bottom cover 4. These locking rods 5 are located outside the sleeve 1 and serve as key components connecting the top cover 3 and the bottom cover 4. Their lower ends penetrate the through hole 6 of the top cover 3 and are threadedly connected to the threaded hole 7 of the bottom cover 4. Tightening the locking rods 5 applies sufficient pressure, ensuring that the top cover 3 and the bottom cover 4 fit tightly against both ends of the sleeve 1, thus guaranteeing the overall sealing and structural stability of the assembly. During installation and disassembly, the operation of the locking rods 5 is relatively simple, requiring no complex tools or techniques, facilitating assembly, maintenance, and replacement by workers, thereby improving work efficiency and reducing labor intensity.

[0027] Furthermore, in the above technical solution, the top cover 3 and the bottom cover 4 are provided with a number of positioning holes 8. The number of positioning holes 8 on the top cover 3 and the bottom cover 4 are arranged in a ring array and correspond to the ends of the number of tubular ceramic membranes 2.

[0028] Furthermore, in the above technical solution, the top cover 3 has multiple through holes 6 along its edge, and the bottom cover 4 has multiple threaded holes 7 at its upper end along its edge. The number and position of the threaded holes 7 correspond to those of the through holes 6. The lower end of the locking rod 5 is threadedly connected to the threaded holes 7 along the edge of the bottom cover 4 through the through hole 6.

[0029] Furthermore, in the above technical solution, limiting rings 14 are fixedly installed on the upper and lower ends of the tubular ceramic membrane 2. The limiting rings 14 at the upper and lower ends of the tubular ceramic membrane 2 are respectively at the bottom of the top cover 3 and the top of the bottom cover 4. The outer diameter of the limiting ring 14 is larger than the diameter of the positioning hole 8.

[0030] Furthermore, in the above technical solution, a connecting part 9 is fixedly installed on the upper end of the bottom cover 4. The connecting part 9 is threadedly connected to the lower outer surface of the sleeve 1. This connection method has a certain degree of tightness and stability, which can effectively prevent the bottom cover from loosening or falling off during operation, ensuring the sealing of the bottom of the component. At the same time, the threaded connection is easy to disassemble. When it is necessary to inspect, clean, or replace the tubular ceramic membrane 2 inside the component, the bottom cover 4 can be unscrewed from the sleeve 1 relatively easily without causing serious damage to the sleeve 1 and the bottom cover 4, which helps to reduce maintenance costs and extend the service life of the component. A cap 11 is installed on the outside of the front opening of the sampling interface 10. The cap 11 protects the sampling interface 10 when sampling is not required, preventing external impurities, dust, or microorganisms from entering the interface and the inside of the sleeve 1, avoiding the impact of contamination on the accuracy of sampling and damage to the ceramic membrane, and ensuring the reliability and stability of the component operation.

[0031] Furthermore, in the above technical solution, the upper end of the tubular ceramic membrane 2 is inserted into the positioning hole 8 of the top cover 3, and the lower end of the tubular ceramic membrane 2 is inserted into the positioning hole 8 of the bottom cover 4.

[0032] The modular ceramic membrane assembly provided by this utility model operates as follows:

[0033] The sampling interface 10 provides a convenient channel for real-time monitoring of the liquid treatment status inside the component. During the operation of the component, a small amount of the treatment liquid can be taken out periodically through this interface for analysis and testing, so as to understand the treatment effect in a timely manner, adjust the operating parameters according to the test results, and ensure that the entire treatment process is always in the best state.

[0034] The inlet pipe 12 and outlet pipe 13 are located on opposite sides of the sleeve 1, with the inlet pipe 12 above and the outlet pipe 13 below, which facilitates a good liquid flow pattern. After the feed liquid enters from above, it can be evenly distributed within the sleeve 1 under gravity and fully contact the tubular ceramic membrane 2. The liquid, after being filtered or treated by the ceramic membrane, flows out from the outlet pipe below. This rational pipe arrangement improves the contact efficiency between the liquid and the ceramic membrane, reduces dead zones and short-circuit phenomena in the liquid flow, thereby enhancing the overall treatment performance and effect of the ceramic membrane module.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
