Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical production equipment, in particular to a new sealing structure for the end of a ceramic membrane tube. Background Art
[0002] As we all know, ceramic membrane tube is an inorganic ceramic membrane, which is an asymmetric membrane formed by special process of inorganic ceramic material. The wall of ceramic membrane tube is densely covered with micropores. Under pressure, the raw material liquid flows inside or outside the membrane tube, small molecules (or liquids) pass through the membrane, and large molecules (or solids) are intercepted by the membrane, so as to achieve the purpose of separation, concentration, purification and environmental protection. Ceramic membrane has many advantages such as high separation efficiency, stable effect, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high temperature resistance, pollution resistance, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, simple operation and maintenance, long service life, etc. It has been successfully applied to many fields such as food, beverage, plant (drug) deep processing, biomedicine, fermentation, fine chemical industry, etc., and can be used for separation, clarification, purification, concentration, sterilization, desalination, etc. in the process.
[0003] In practical applications, due to the high cost of ceramic membrane tubes, the brittleness of the materials and the low elasticity, certain difficulties are brought to the molding and processing of the membrane and the sealing of the media inside and outside the membrane tube. In particular, the sealing of the membrane tube ends has a great impact on equipment design and cost control. Since the ceramic membrane tube is relatively brittle, the ends cannot be processed into a usable sealing surface. Therefore, in conventional applications, the outer wall of the membrane tube is used as the sealing surface, and an O-ring is set at the connection between the tube sheet and the ceramic membrane tube for sealing. However, this type of sealing is limited by the opening accuracy and size of the tube sheet. The opening rate on the tube sheet of the same size is low, and the number of membrane tubes that can be installed is small; in addition, during the installation and application process, since the membrane tube passes through more tube sheets, the concentricity of the openings on the tube sheet is poor, and the stress of the concentricity deviation causes the membrane tube to break easily during installation. Moreover, the ceramic membrane tube is only sealed by the O-ring and limits the axial displacement, resulting in low sealing strength and easy leakage. Utility Model Content
[0004] In order to solve the above problems, our ultimate goal is to find a simple and effective sealing form, improve the utilization efficiency of ceramic membrane tubes, and save costs.

The specific technical scheme is a new sealing structure for the end of a ceramic diaphragm tube, including a ceramic diaphragm tube, an embedded component, a sealing component and an external tensioning component. The new sealing structure for the end of the ceramic diaphragm tube adopts an internal sealing type of the tube, the sealing component is located on the card groove of the embedded component, the embedded component is located inside the ceramic diaphragm tube, the external tensioning component is clamped on the end of the ceramic diaphragm tube, and is threadedly connected to the embedded component, and the sealing component is pressed inside the ceramic diaphragm tube to seal with the ceramic diaphragm tube.
[0006] In the above sealing structure, the embedded part and the external tensioning part adopt a threaded connection or a snap connection or other flexible connection form, and have a self-locking effect. The sealing part adopts an interference type fluoro rubber ring.
