Abstract
The utility model relates to a diaphragm filter plate for a press filter, which comprises a core plate and press diaphragms positioned on the upper and the lower sides of the core plate, and the core plate and the press diaphragms are connected through bolts. Two grooves and two O-shaped rubber seal rings are arranged on the core plate. The core plate and the press diaphragms in the utility model are connected through the bolts, resulting in simple structure, convenient replacement and low use cost; and the press diaphragms and the core plate are sealed via the two O-shaped rubber seal rings, which ensures reliable sealing performance.
Description
Technical field
The utility model relates to a kind of integral type membrane filter plate that is used to the filter press of pressing function.
Background technology
The membrane filter plate of the filter press of band pressing function mainly contains following two kinds of forms:
1, split type diaphragm of rubber filter plate, promptly Zhong Jian compressive plate is conventional RPP, and the two sides covers the rubber squeeze diaphragm, and the diaphragm of rubber upper end is fixed on the RPP compressive plate, and the bottom is unfixing, and integral hanging is on the RPP compressive plate.Such structure, because squeeze diaphragm adopts rubber to make, squeeze pressure is low, filter cake does not reach desirable water content requirement; And the service life of rubber is lower.
2, integral solder formula membrane filter plate, promptly diaphragm plate central layer and squeeze diaphragm plate are the RPP material all, and two squeeze diaphragm plates are welded on the diaphragm plate central layer.Such structure can reach squeezes effect preferably, if whole welded type membrane filter plate scrapped but the squeeze diaphragm plate damages, has increased the use cost of filter press use producer.
Summary of the invention
The utility model provides a kind of use cost low diaphragm filter board of filter press at above-mentioned the deficiencies in the prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of diaphragm filter board of filter press, comprise central layer and be positioned at the described central layer squeeze diaphragm of both sides up and down, it is characterized in that, the edge of described central layer and described squeeze diaphragm utilizes some screw elements to interconnect, make the edge of described central layer and squeeze diaphragm fit tightly, form cavity at the middle part of described central layer and squeeze diaphragm.
The surface that described central layer and squeeze diaphragm fit is provided with groove, is provided with the sealing ring that seals in described groove.Described groove has two, and described sealing ring has twice accordingly, and described screw element is between described two grooves.Bight at central layer is provided with liquid outlet, and described liquid outlet is communicated with described cavity; Be provided with sealing ring between central layer around liquid outlet and the squeeze diaphragm.Described sealing ring is an O type rubber seal.
Technique effect of the present utility model is: 1, central layer of the present utility model is connected by screw with squeeze diaphragm, simple in structure, be convenient for changing, use cost is low.2, seal by twice O type rubber seal between squeeze diaphragm and the central layer, guarantee reliable sealing performance.3, also be provided with sealing ring around the liquid outlet, prevent that liquid from entering the faying face of squeeze diaphragm and central layer, guaranteed the sealing of squeezing air simultaneously better.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
See Fig. 1 and Fig. 2, the squeeze diaphragm 1 that the utility model comprises central layer 5 and is positioned at central layer both sides about in the of 5, central layer 5 and squeeze diaphragm 1 all adopt the RPP material, interconnect by screw element 6 at the edge of central layer 4 with two-layer squeeze diaphragm 1., make the described central layer 5 and the edge of squeeze diaphragm 1 fit tightly, at the middle part formation cavity of described central layer 5 with squeeze diaphragm 1.Screw element 6 is along edge distribution one circle of membrane filter plate, and quantity is determined on demand.Screw element 6 can be a screw.
Be provided with the groove of annular on the upper and lower surface that central layer 5 and squeeze diaphragm 1 are fitted mutually, described annular groove has two, is provided with two seals circle 2,4 in the groove, and two seals has enclosed good sealing effectiveness.And described screw 6 is between two grooves.During in order to avoid work, be positioned at the cavity leaked liquid.
In the bight of central layer 5 liquid outlet 7 is set, described liquid outlet 7 is communicated with described cavity, so that the liquid in the cavity is drawn from liquid outlet 7; On the central layer 5 around the membrane filter plate liquid outlet 7, also be provided with sealing ring 3 one.Sealing ring 3 is approximately triangle, can prevent that liquid from entering the faying face of squeeze diaphragm 1 and central layer 5, has guaranteed the sealing of squeezing air simultaneously better.Above-mentioned sealing ring 2,3,4 is O type rubber seal.
Central layer of the present utility model 5 and squeeze diaphragm 1 interconnect by screw, when central layer 5 or squeeze diaphragm 1 damage, can take replacing apart, and use cost is low.
Claims (5)
1. diaphragm filter board of filter press, comprise central layer (5) and be positioned at described central layer (5) squeeze diaphragm of both sides (1) up and down, it is characterized in that, described central layer (5) utilizes some screw elements (6) to interconnect with the edge of described squeeze diaphragm (1), make the described central layer (5) and the edge of squeeze diaphragm (1) fit tightly, at the middle part formation cavity of described central layer (5) with squeeze diaphragm (1).
2. according to the described diaphragm filter board of filter press of claim 1, it is characterized in that described central layer (5) is provided with groove with the surface that squeeze diaphragm (1) fits, and is provided with the sealing ring (2,4) that seals in described groove.
3. according to the described diaphragm filter board of filter press of claim 2, it is characterized in that described groove has two, described sealing ring (2,4) has twice accordingly, and described screw element (6) is between described two grooves.
4. according to the described diaphragm filter board of filter press of claim 1, it is characterized in that in the bight of central layer (5) liquid outlet (7) is set, described liquid outlet (7) is communicated with described cavity; Liquid outlet (7) on every side central layer (5) and squeeze diaphragm (1) between be provided with sealing ring (3).
5. according to each described diaphragm filter board of filter press in the claim 2～4, it is characterized in that described sealing ring (2,3,4) is an O type rubber seal.
