Description
Technical field
The present invention relates to water treatment facilities, specifically relates to hermetically sealed hollow ceramic flat membranes filter element.
Background technology
Earthenware slab membrane bioreactor is as a kind of new and effective sewage disposal technology, it has also become sanitary sewage, especially
It is treatment technology indispensable in industrial wastewater and extreme environment wastewater treatment.
It is ceramic membrane bioreactor that membrane bioreactor is wide variety of at present（PC-MBR）, PC-MBR has following
Main feature：Treatment effeciency is high, effluent quality is good, facility compact, floor space is small, intensity is high, water flux is big, long lifespan, list
Potential energy consumption it is low, it is easy realization automatically control, operational management is simple, operation expense is low.But because ceramic membrane is extrusion forming
Plate type ceramic diaphragm, two needs to encapsulate plug, and needs to be sealing adhesive with glue, to ensure sealing and durable
Property.Because diaphragm is inorganic material, plug is organic material mostly, and two kinds of materials are bonded and there is glue type selecting and operation
Property the problem of, degumming seepage of the plug position because of adhesive strength deficiency easily occurs in use, and meet when expanding with heat and contract with cold glue with it is stifled
Head adhesive property declines, and causes diaphragm overall performance to decline and the problems such as the lost of life.
Utility model content
For problematic in the presence of above-mentioned prior art, the utility model provides a kind of ceramic diaphragm can be complete with plug
The hollow ceramic flat membranes filter element of sealing.
The technical problems to be solved in the utility model is adopted the technical scheme that：The hermetically sealed hollow flat ceramic
The upper plug head and lower end cap that film filtering element includes ceramic diaphragm, is connected with ceramic diaphragm upper and lower side, the upper plug head is with
Water leg is provided with plug, is provided with the outlet pipe being connected with water leg on upper plug head, on the upper plug head and lower end cap
Ceramic diaphragm fixing groove and collection glue groove are provided with, the water leg, ceramic diaphragm fixing groove and collection glue groove are stepped successively,
Fixed rib is arranged at intervals with the ceramic diaphragm fixing groove, the side of the collection glue groove is provided with reticulate pattern.
The utility model effectively solves the adhesive strength deficiency of various flat ceramic diaphragm encapsulation plug, adhesive property
When declining the problem of fast and bonding the problem of glue easy seepage；And reduction glue caused by expanding with heat and contract with cold is Nian Jie with plug
The problem of hydraulic performance decline.Apparent size difference is caused in the easy shift position of plug after the completion of can also solving the problems, such as bonding.Have
Faster, adhesive property is more preferable for operating speed, the advantages such as product quality improves.The core parts of the utility model flat ceramic diaphragm
It is high-purity Al2O3 structure of composite membrane using the microporous barrier on hollow ceramic flat membranes piece, diaphragm has high mechanical strength, pressure-bearing energy
Power is strong, chemical stability is good, porosity distribution is uniform, water flux is big, resistance tocrocking is good, is readily cleaned regeneration, service life
Long, the features such as economy is high, solve cleaned in organic membrane component operation it is difficult, safeguard it is cumbersome, can not repeatedly backwash, change
Frequently, use environment requires high, service life is short, easily by acid and alkali corrosion, not organic solvent-resistant, operating cost height, floor space
The problems such as big, the difficulty of blowdown is easily caused, effectively increase the service life and reliability of membrane bioreaction device.And use
The ceramic membrane crossed can be reclaimed for other ceramics, reduce discarded object.The utility model is carried out using single-iris
Plug encapsulates, can effectively avoid because monolithic breaks down and caused by whole unit replacement the problem of, and can be flexible as needed
Form component.Facilitate the operation such as in-site installation and maintenance.
The flat ceramic membrane component production technology：The inorganic material such as high purity aluminium oxide are through ball milling, pugging, shaping, high temperature
Fire, cut fixed length, end face fixed thick grinding, outward appearance and performance checking, cleaning, drying, encapsulation plug, adhesive curing, performance checking
Deng.In order to solve the above technical problems, following technical scheme used by the utility model：To solve the problems, such as bonding force deficiency,
Increase on the basis of existing process：Plug gluing surface feather plucking, cleaning, drying process.Plug is moulding, and frosted processing is done on surface,
But smooth surface be present, cause glueability insufficient, and during the moulding demoulding there is releasing agent, it is necessary to be purged in surface,
Feather plucking is carried out in inner face gluing surface and cleaning treatment can effectively solve the smooth hypodynamic situation of bonding of bonding plane.
Gap for plug in solution bonding process and diaphragm be present and easily cause plug to loosen, gluing out-of-flatness, glue holds
The problems such as easy to leak is to plug inside, the utility model is using increase rib technique：Increase in the diaphragm installation site side of plug
Sinew adding strip, because plug uses plastic injection piece, plug edge can be extruded when diaphragm size is normal or diaphragm size is bigger than normal, is entered
Row close-fitting, diaphragm and plug cooperation can be made not to loosen, convenient working, can also prevent glue from flowing into plug water passage.Plastics
The plug of moulding is bigger than the coefficient of expansion of flat ceramic diaphragm, and both carry out close-fitting, and air and water temperature are blocked up when changing
Head somewhat expansion will not cause space, can keep adhesive strength.Avoid occurring because shrinkage ratio is different and caused by loose glue phenomenon.
