Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane module technology, specifically a self-cleaning ceramic membrane module. Background Technology

[0002] For materials containing suspended solids and particulate matter, the main method of purification is filtration to separate the solid-liquid mixture. Currently, the commonly used filter media are various organic and inorganic membranes. Inorganic membranes are manufactured using traditional ceramic sintering processes. In recent years, with the development of science and technology, inorganic membrane separation technology has been widely used in industries such as chemical, pharmaceutical, environmental protection, food, and beverage. Ceramic membranes, on the other hand, have been widely used in microfiltration and ultrafiltration due to their significant characteristics such as good chemical stability, acid and alkali resistance, organic solvent resistance, resistance to microbial erosion, and strong anti-fouling ability. Ceramic membranes are divided into tubular ceramic membranes and plate ceramic membranes.

[0003] When using plate ceramic membranes, a lot of impurities accumulate inside. Excessive impurities not only affect the filtration effect of the ceramic membrane but also cause blockage inside the membrane. Therefore, it is necessary to clean the inside of the plate ceramic membrane regularly. However, the existing cleaning method requires disassembling the ceramic membrane module and placing it in a special cleaning device to clean the ceramic membrane. This cleaning method requires disassembling the ceramic membrane, which is very time-consuming and labor-intensive, increasing the cleaning cost and indirectly reducing the overall purification efficiency of the ceramic membrane module.

[0004] Therefore, this invention provides a self-cleaning ceramic membrane module to solve the above problems. Utility Model Content

[0006] This invention provides a self-cleaning ceramic membrane module, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A self-cleaning ceramic membrane module includes a housing with openings on both sides. A first circular plate for sealing the housing is fixedly installed on the left side of the housing, and a second circular plate for sealing the housing is fixedly installed on the right side of the housing. Multiple equidistantly distributed plate-type ceramic membranes are fixedly installed between the first and second circular plates, with the plate-type ceramic membranes penetrating the first and second circular plates respectively. A first protective shell is installed on the side of the first circular plate, and a second protective shell is fixedly installed on the side of the second circular plate. A sealing component is provided inside the second protective shell to seal the right side of the plate-type ceramic membranes. A first water outlet pipe is fixedly inserted into the right side of the top surface of the housing, and a second water outlet pipe is fixedly inserted into the left side of the bottom surface of the housing.

[0010] As a preferred technical solution of this application, a feed pipe is fixedly inserted into the side of the first protective shell, and a discharge pipe is fixedly inserted into the side of the second protective shell.

[0011] As a preferred technical solution of this application, a drain pipe is fixedly inserted into the bottom of the first protective shell, and a control valve is provided inside the drain pipe.

[0012] As a preferred technical solution of this application, the sealing assembly includes a bolt threaded into the top of the second protective shell, and a circular baffle tightly attached to the side of the second circular plate is rotatably mounted on the bottom of the bolt via a bearing. The side of the circular baffle has a plurality of through holes respectively adapted to the plate ceramic membrane.

[0013] As a preferred technical solution of this application, positioning grooves are provided on both sides of the inner wall of the second protective shell, and positioning blocks that are fixedly installed on the side of the circular baffle are slidably inserted into the positioning grooves.

[0014] As a preferred technical solution of this application, two symmetrical auxiliary baffles are fixedly installed on the bottom surface of the circular baffle.

[0015] As a preferred technical solution of this application, when the positioning block contacts the bottom of the inner wall of the positioning groove, the through hole on the side of the circular baffle is connected to the channel of the plate ceramic membrane, and when the positioning block contacts the top of the inner wall of the positioning groove, the circular baffle will seal the channel of the plate ceramic membrane.

[0016] (III) Beneficial Effects

[0017] The ceramic membrane assembly used in this invention allows for internal cleaning without disassembling the plate ceramic membrane after use, improving cleaning efficiency. Furthermore, no additional operations are required during cleaning, enhancing the ease of cleaning. Specifically, the control valve is opened, and the bolt is tightened. The bolt causes the circular baffle to move upwards until the positioning block contacts the top of the inner wall of the positioning groove. Tightening the bolt then stops, sealing the right side of the plate ceramic membrane. Clean water is then introduced into the housing through the first and second outlet pipes. Once the housing is full, the clean water seeps into the plate ceramic membrane, rinsing its interior. The rinsed wastewater enters the first protective shell and is eventually discharged through the drain pipe. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: This utility model provides a self-cleaning ceramic membrane module, such as... Figure 1-4As shown, the ceramic membrane assembly includes a housing 1 with openings on both sides. A first circular plate 2 for sealing the housing 1 is fixedly installed on the left side of the housing 1, and a second circular plate 3 for sealing the housing 1 is fixedly installed on the right side of the housing 1. Multiple plate-type ceramic membranes 12 are fixedly installed between the first circular plate 2 and the second circular plate 3. The first circular plate 2 and the second circular plate 3 are respectively penetrated by the plate-type ceramic membranes 12. A first protective shell 4 is installed on the side of the first circular plate 2, and a second protective shell 5 is fixedly installed on the side of the second circular plate 3. A sealing component is provided inside the second protective shell 5 to seal the right side of the plate-type ceramic membrane 12. A first water outlet pipe 8 is fixedly inserted into the right side of the top surface of the housing 1, and a second water outlet pipe 9 is fixedly inserted into the left side of the bottom surface of the housing 1.

[0026] In Example 2, based on Example 1, a feed pipe 6 is fixedly inserted into the side of the first protective shell 4, and a discharge pipe 7 is fixedly inserted into the side of the second protective shell 5.

[0027] In Example 3, based on Example 1, a drain pipe 10 is fixedly inserted into the bottom of the first protective shell 4, and a control valve is provided inside the drain pipe 10.

[0028] In Example 4, based on Example 1, the sealing assembly includes a bolt 11 threaded into the top of the second protective shell 5. The bottom of the bolt 11 is rotatably mounted with a circular baffle 13 that is tightly attached to the side of the second circular plate 3 via a bearing. The side of the circular baffle 13 has a plurality of through holes 14 that are adapted to the plate ceramic membrane 12.

[0029] In Example 5, based on Example 1, positioning grooves 15 are provided on both sides of the inner wall of the second protective shell 5, and positioning blocks 16 fixedly installed on the side of the circular baffle 13 are slidably inserted into the positioning grooves 15.

[0030] In Example 6, based on Example 1, two symmetrical auxiliary baffles 17 are fixedly installed on the bottom surface of the circular baffle 13. The auxiliary baffles 17 can improve the sealing effect of the circular baffle 13 and avoid incomplete sealing.

[0031] In Example 7, based on Example 1, when the positioning block 16 contacts the bottom of the inner wall of the positioning groove 15, the through hole 14 on the side of the circular baffle 13 is connected to the channel of the plate ceramic membrane 12. When the positioning block 16 contacts the top of the inner wall of the positioning groove 15, the circular baffle 13 will seal the channel of the plate ceramic membrane 12.

[0032] Working principle:

[0033] Wastewater to be filtered is fed into the first protective shell 4 through the feed pipe 6. Once the first protective shell 4 is full, the wastewater enters the plate ceramic membrane 12, which filters the material. The filtered clean water passes through the side of the plate ceramic membrane 12 into the shell 1 and is finally discharged from the first outlet pipe 8 and the second outlet pipe 9. Concentrated wastewater enters the second protective shell 5 and is discharged from the discharge pipe 7. This completes the wastewater filtration process. When cleaning the device is required, the operator simply opens the control valve and tightens bolt 11. Bolt 11 will move the circular baffle 13 upward until the positioning block 16 contacts the top of the inner wall of the positioning groove 15. Then, stop turning the bolt 11. At this time, the circular baffle 13 will seal the right side of the plate ceramic membrane 12. Then, clean water will be introduced into the housing 1 from the first water outlet pipe 8 and the second water outlet pipe 9. After the housing 1 is filled with clean water, the clean water will seep into the plate ceramic membrane 12 and rinse the inside of the plate ceramic membrane 12. The rinsing wastewater will enter the first protective shell 4 and finally be discharged from the drain pipe 10. At this time, the purpose of cleaning the plate ceramic membrane 12 is completed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
