Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a ceramic membrane filtration device. Background Technology

[0002] A ceramic membrane filter is a filtration device with inorganic ceramic membrane tubes as its core component. The inorganic ceramic membrane tubes are evenly distributed inside the ceramic membrane filter, and both ends of the inorganic ceramic membrane tubes are fixed inside the ceramic membrane filter by a fixing mechanism.

[0003] However, existing ceramic membrane filtration equipment does not pre-filter the liquid entering the inorganic ceramic membrane tube, allowing large particles to enter. This necessitates frequent, time-consuming, and labor-intensive cleaning of the inorganic ceramic membrane tube. Furthermore, the presence of supporting components at both ends results in low overall strength of the inorganic ceramic membrane tube, making it prone to bending and damage, thus shortening its lifespan. Therefore, innovative designs based on existing ceramic membrane filtration equipment are urgently needed to address these issues. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ceramic membrane filtration device, comprising a housing, wherein ceramic membrane tubes are uniformly arranged inside the housing through a fixing mechanism, the ceramic membrane tubes pass through a support frame, the support frame is evenly distributed on the ceramic membrane tubes, and the housing and the support frame are connected to each other; The housing is equipped with a filter screen installed inside, and the filter screen is set at an angle downwards. A drain pipe is provided on one side of the housing near the filter screen.

[0006] Preferably, the end of the sewage pipe is provided with a sealing cap.

[0014] 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.

[0015] Please see Figure 1-6This utility model provides a technical solution: a ceramic membrane filtration device, including a shell 1, with ceramic membrane tubes 2 evenly arranged inside the shell 1 by a fixing mechanism. The ceramic membrane tubes 2 slide through the interior of a support frame 3, and the support frame 3 has water flow holes. The support frame 3 is evenly distributed on the ceramic membrane tubes 2, and the outer side of the support frame 3 is fixed to the inner side of the shell 1, which increases the overall strength of the ceramic membrane tubes 2, reduces the probability of deformation of the ceramic membrane tubes 2, and extends the service life of the ceramic membrane tubes 2. Inside the outer casing 1, above the ceramic membrane tube 2, a filter screen 4 is fixed. The diameter of the filter holes on the ceramic membrane tube 2 is smaller than that on the filter screen 4. The filter screen 4 is set at an angle downwards. A drain pipe 5 is fixedly connected to one side of the outer casing 1 near the filter screen 4. A sealing cap 6 is provided at the end of the drain pipe 5. A sealing gasket is engaged inside the sealing cap 6. The filter screen 4 can filter large particles of impurities that enter the ceramic membrane tube 2 in advance, reducing the chance of the ceramic membrane tube 2 becoming clogged. This allows impurities at the top of the filter screen 4 to flow to the bottom of the filter screen 4 and enter the drain pipe 5, facilitating the quick cleaning of large particles of impurities inside the outer casing 1.

[0016] The lowest point inside the drain pipe 5 is in contact with the lowest point at the top of the filter screen 4, which facilitates the flow of impurities on the filter screen 4 into the interior of the drain pipe 5.

[0017] The fixing mechanism includes a base plate 7. The bottom of the outer shell 1 is fixed to the base plate 7 by bolts and nuts. A sealing gasket is provided between the base plate 7 and the outer shell 1. A support ring is fixed to the inner side of the outer shell 1. An inner plate 8 is fixed to the top of the support ring by bolts. Clamping rings 9 are evenly distributed and fixed to the bottom of the inner plate 8 and the top of the base plate 7. A sealing ring is fixed to the inner side of the clamping ring 9. The inner side of the sealing ring is in contact with the outer side of the end of the ceramic membrane tube 2. Liquid inlet holes 10 are evenly opened on the inner plate 8. The liquid inlet holes 10 are interconnected with the clamping rings 9, so that both ends of the ceramic membrane tube 2 can be fixed.

[0018] The diameter of the ceramic membrane tube 2 is larger than the diameter of the liquid inlet hole 10, ensuring that the end of the ceramic membrane tube 2 will not pass through the interior of the liquid inlet hole 10.

[0019] The top of the outer casing 1 is fixed with a top plate 11 by bolts and nuts. A sealing gasket is provided between the outer casing 1 and the top plate 11. The top of the top plate 11 is fixedly connected to an inlet pipe 12, and the bottom of one side of the outer casing 1 is fixedly connected to an outlet pipe 13, which increases the sealing between the outer casing 1 and the top plate 11.

[0020] Working principle: When using this ceramic membrane filtration equipment, the liquid to be filtered first enters the interior of the outer shell 1 through the inlet pipe 12. Large particles of impurities in the liquid are trapped by the filter screen 4. Since the filter screen 4 is set at an angle downward, the large particles of impurities on the filter screen 4 slide downward and enter the interior of the drain pipe 5. The pre-filtered liquid enters the interior of several ceramic membrane tubes 2 through several inlet holes 10. Small particles of impurities in the liquid remain inside the ceramic membrane tubes 2. The filtered liquid enters the interior of the outer shell 1 and is finally discharged through the outlet pipe 13. When it is necessary to clean the large particles of impurities inside the drain pipe 5, rotate the sealing cover 6. Since the sealing cover 6 and the drain pipe 5 are threadedly connected, the drain pipe 5 is opened, and the large particles of impurities inside the drain pipe 5 are discharged. This facilitates the cleaning of large particles of impurities inside the outer shell 1, avoids large particles of impurities entering the interior of the ceramic membrane tubes 2, reduces the number of times the ceramic membrane tubes 2 need to be cleaned, and reduces labor intensity.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
