Description
Technical field
The invention belongs to membrane filter plate technical fields, and in particular to high resiliency diaphragm membrane filter plate.
Background technique
The membrane filter plate of general filter press is had altogether three and is formed by two flexible sheets and intermediate core plate, is passed through external pressure
It squeezes medium (water or compressed air etc.) to enter in the chamber between intermediate core plate and two latallaes, makes diaphragm bulging to filter
The filter cake formed in room is squeezed, and then preferably realizes separation of solid and liquid, improves the solid content of filter cake, wherein diaphragm is main
Dynamic component, but due to being limited by intermediate core plate, diaphragm moving range is smaller, and the squeezing effect of filter cake will receive certain shadow
It rings, causes the moisture content of part filter cake higher, and since membrane filter plate is three compositions, intermediate core plate is solid core slab, weight
Heavier higher cost, and the technique of three combinations is once molded and also results in cost increase；Therefore need to provide a kind of user
Just, the high resiliency diaphragm membrane filter plate that manufacturing cost is low, squeezing effect is good.
Summary of the invention
The purpose of the invention is to provide a kind of high resiliency diaphragm easy to use, manufacturing cost is low, squeezing effect is good
Piece membrane filter plate.
The object of the present invention is achieved like this: high resiliency diaphragm membrane filter plate, it be connected by two panels diaphragm and
At every piece of diaphragm includes outline border, inner ring, boss and elastic squeeze and filter film, the outline border and inner ring of two pieces of diaphragms
Be composed of a fixed connection high resiliency diaphragm membrane filter plate, and closed squeezing chamber is formed between two pieces of diaphragms, described
It is fixedly connected with flexible squeeze and filter film between the inner ring of diaphragm and outline border, is fixedly connected on the elastic squeeze and filter film
There are salient point and boss, the outline border right part is provided with the squeezing fluid conveying for being connected to and squeezing chamber between elastic squeeze and filter film
Hole, the outline border four corners are provided with water eluate leadout hole, and the water eluate export bore ends, which are provided with, washes out
Fluid apertures, the washing fluid hole end are provided with water eluate inclined hole.
The diaphragm is to be preset at injection molding as insert by the elastic squeeze and filter film in advance by injection molding
In mold, outline border, boss, the molten weldering of inner ring are connected to become an entirety by being molded again.
Boss and salient point on the elastic squeeze and filter film are uniformly arranged within outline border.
The outline border and inner ring of two pieces of diaphragms are by being symmetrically welded or being bonded composition high resiliency diaphragm diaphragm
Filter plate, two diaphragm welding positions are that outline border welds fusion face and inner ring welds fusion face, and welding surface must not exceed
Minimum groove flat on elastic squeeze and filter film, minimum groove flat need to be kept at a distance from 1mm or more with intermediate welding surface.
The welding of two pieces of diaphragms relates only to the welding of outline border welding fusion face and inner ring welding fusion face, weldering
It connects position and is not related to elastic squeeze and filter film and boss.
Outline border, inner ring and the boss uses hard material, and elastic squeeze and filter film uses elastomeric material.
The elastic squeeze and filter film upper and lower surfaces symmetric position of boss periphery inside the elastic squeeze and filter film point
It is not provided with support bar, the sectional area of contour corresponding to the support bar of lower surface is less than the section of upper surface support bar contour
Product.
The elastic squeeze and filter film kept between the k level and welding plane of lug boss position it is certain away from
From minimum range is greater than 0.5mm, and maximum distance is no more than 5mm.
Envelope surface has certain tilt angle in the elastic squeeze and filter film first lap, greater than 3 ° less than 30 °, first lap
Peripheral surface is parallel with envelope surface in first lap or has the angle of very little, and included angle is not more than 5 °.
The elastic squeeze and filter film may be provided with the lock ring phase with elastic squeeze and filter film end with boss junction
The deep trouth of adaptation.
Beneficial effects of the present invention: membrane filter plate is added three groups of intermediate core plate by the present invention by two traditional diaphragms
At changing into only there are two the new membrane filter plate of diaphragm composition, intermediate core plate is eliminated, diaphragm is mainly by outline border, inner ring, bullet
Property the composition such as squeeze and filter face and boss first will be pre- by the elastic squeeze and filter film of injection molding in advance when making diaphragm
It sets in injection mold, then outline border, boss, inner ring and the molten weldering of elastic squeeze and filter film is connected to become one by quadric injection mould
It is whole, solderings then are carried out to two pieces of diaphragms again and become high resiliency diaphragm membrane filter plate, by outline border, inner ring and
The molten weldering of flexible sheet connects to replace supporting role of the intermediate core plate to flexible sheet, so that new membrane filter plate own wt is big
Amplitude mitigates, and due to not having the limitation of intermediate core plate, resilient movement range increases diaphragm membrane, the filter cake squeezing intracavitary to filter chamber
Effect has biggish promotion, and the moisture content of filter cake is greatly lowered, due to not having core plate to make only one inside membrane filter plate
Chamber is squeezed, so that the eardrum pressure uniformity of membrane filter plate two sides filter chamber diaphragm, and squeezing pressure suffered by the filter cake of two sides
Power is also identical, and cake of filter-press moisture content also reaches unanimity；Total, the present invention has rational design, have easy to use, manufacture at
This advantage low, that squeezing effect is good.
