Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a ceramic tube filtering device for water treatment. Background Art

[0002] A ceramic filter tube is a filter element made of ceramic material, which has a microporous structure and can effectively filter impurities and particulate matters in liquids or gases. Its excellent properties such as high temperature resistance, corrosion resistance, and wear resistance enable the ceramic filter tube to maintain a good filtering effect under various harsh working conditions. Its main working principle is a substance separation technology based on the sieving effect of porous ceramic media. That is, under the drive of pressure, the raw liquid flows inside or outside the membrane, and small molecule substances (liquids) penetrate through the microporous membrane in a direction perpendicular to it, while macromolecule substances (or solid particles) are intercepted by the membrane, thus achieving the purpose of filtration.

[0003] In the use process of most existing ceramic tube filtering devices for water treatment, it is necessary to connect the ceramic tube base with the water outlet end of the filtering device, and the two are often sealed by a rubber ring. However, during long-term use, the rubber ring is prone to aging, resulting in a gap between the ceramic tube base and the water outlet end of the filtering device. Under the condition of high water pressure, it is easy for the unfiltered water to enter the water outlet end through the gap, polluting the filtered water and causing great inconvenience to the normal use of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a ceramic tube filtering device for water treatment to solve the technical problems mentioned in the above background art.

[0005] The technical problems to be solved by the utility model can be realized through the following technical solutions:

[0006] A ceramic tube filtering device for water treatment includes a filtering box, and a water inlet pipe and a water outlet pipe arranged at both ends of the filtering box;

[0007] A connecting pipe matching with the water outlet pipe is arranged on one inner wall of the filtering box. An annular groove is formed on the inner wall of the connecting pipe, and through grooves communicating with the annular groove are symmetrically formed on the outer side of the connecting pipe. An airbag sleeve is arranged inside the annular groove, and a sealing sleeve is attached to the inner wall of the airbag sleeve. A main airbag is arranged on the inner wall of the filtering box where the connecting pipe is located, and the main airbag surrounds the outer side of the connecting pipe. An air delivery pipe is arranged at the output end of the main airbag, and the air delivery pipe penetrates through the inside of the through groove and is communicated with the airbag sleeve;

[0008] One side of the connecting pipe is provided with a base, one end of the base is provided with an insertion pipe, and the outer side of the insertion pipe is fitted with the inner wall of the connecting pipe. A first flange is arranged on the outer side of the connecting pipe near the base, and a second flange matching the first flange is arranged on the outer side of the end of the base where the insertion pipe is provided. The second flange and the first flange are fixedly connected by bolts.

[0009] As a further scheme of the utility model: several shunt ends are arranged at the other end of the base, and a ceramic pipe is sleeved inside the shunt end.

[0010] As a further scheme of the utility model: a main flow chamber communicating with the shunt end is opened inside the base, and a water outlet communicating with the main flow chamber is opened at the end of the base where the insertion pipe is provided, and the water outlet is located inside the insertion pipe.

[0011] As a further scheme of the utility model: a sealing retaining ring matching the insertion pipe is arranged around the inner wall of the connecting pipe, and the sealing retaining ring is located behind the annular groove.
