Description
Technical field
The utility model is related to filtration art, more particularly to a kind of plate type membrane component.
Background technology
Plate type membrane component, hollow fiber film assembly, tubular membrane component are conventional filter elements.At home, generally use
Be hollow fiber film assembly and plate type membrane component.Hollow fiber film assembly easily occurs fracture of wire under higher filter pressure and showed
As, causing the later stage to be runed, complex process, cost are higher, and the frequency that backwash and medicine are washed also is far above plate type membrane component, therefore,
Universal not high, the generally 2-3 of the service life of hollow fiber film assembly, and plate type membrane component can be maintained at 5-7.In addition,
The sludge concentration scope that hollow fiber film assembly can be handled is in 4000-8000mg/L, and the dirt that plate type membrane component can be handled
Mud concentration range can reach 8000-10000mg/L.For the replacing in later stage, the film fracture of wire amount of hollow fiber film assembly reaches
20% is accomplished by whole replacings, and plate type membrane component need to only change diaphragm.
The diaphragm material that existing plate type membrane component is mainly used is plastics, filter paper, ceramic membrane etc..Have the following disadvantages：
1) filter pressure for the plate type membrane component being made up of the diaphragm of the materials such as plastics, filter paper is low, it is impossible to carry out backwash；Simultaneously as
The limitation of material, plate type membrane component can not be applied to high temperature and soda acid strong corrosive environment；2) chemistry of ceramics plate type membrane module is steady
Qualitative good, acid and alkali-resistance, high mechanical strength, but the characteristic of ceramic material provides hotbed for fouling, and backwash effect is low, scale formation
Than more serious, the principal element as its life-span of influence；3) ceramic material speciality itself result in the presence of ceramics plate type membrane module
Serious brittleness at room temperature so that the features such as plate type membrane component has that thermal shock resistance is poor, not machinable, can not be welded to connect.
Existing plate type membrane component generally includes two diaphragms and cavity, and the opposite side of the cavity is loose structure,
The diaphragm is mutually bonded with many holes mechanisms, the net liquid after membrane filtration flowed out from the hole of loose structure after from cavity
The liquid outlet discharge of setting.Because bonding force is weaker, therefore usually there is the phenomenon that diaphragm is mutually peeled off with loose structure, cause
Plate type membrane component loses the function of filtering, serious reduction product quality and raising production cost.
Utility model content

As the further improvement of above-mentioned plate type membrane component, the height of the support column is 2-5mm.When the height of support column
It is closer to the distance due to dictyosome and diaphragm during less than above-mentioned parameter scope, therefore can still play certain inhibition to stoste,
Lift the DeGrain of effective filtration area；When the height of support column is higher than above range, the distance of diaphragm and dictyosome compared with
Greatly, when by larger filter pressure and backwash pressure, the contact point of diaphragm and support column can produce larger local assault
Power, diaphragm cannot get the limitation of dictyosome easily because occurring more serious metaboly.Further, contact of the support column with diaphragm
Area is preferably 9-100mm2；Further, the contact surface of support column and diaphragm is conveniently of circular shape.
As the further improvement of above-mentioned plate type membrane component, first framework passes through the convex of mutual cooperation with second framework
Rise and groove connection.Raised cooperated with groove belongs to a kind of dismountable connected mode, so can be tearing open for membrane module
Unload and install simpler, contribute to the replacing of diaphragm, be obviously improved disassembly efficiency.It is of course also possible to use other dismountable
Connected mode, such as using bolt assembly connection.
As the further improvement of above-mentioned plate type membrane component, one group of relative side of first framework is provided with out liquid
