Liquid may pass through filter cloth and flow out along the groove on filter plate surface；In order to being additionally separated full of the filtrate in filter cake in filter frame
Out, it needs to squeeze filter plate, extruded filter plate further squeezes out filtrate, and it is after squeezing that it is indoor, which to remain in filter,
Semisolid filter residue, separately filter plate and filter frame, removal filter residue compress filter plate and filter frame again at this time, start subsequent work circulation.
But find in actual use, the filter plate of conventional plate and frame filter press is made of steel, then in steel table
Face processes groove and carries out water conservancy diversion, and not only processing is complicated, and the weight of product is larger, inconvenient to use；Simultaneously because when squeezing
Adjacent filter plate is rigid contact, bad so as to cause squeezing effect；Therefore, it is above-mentioned to solve to need a kind of completely new filter-plate structure
Problem.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of easily manufactured, light-weight and extruding filtering effects
Fruit good filter press ethylene propylene diene rubber filter plate.
Purpose of the utility model is realized as follows:
A kind of filter press ethylene propylene diene rubber filter plate, the filter plate includes rubber slab, and the material of the rubber slab is
Ethylene propylene diene rubber is provided with feed liquor macropore in the middle part of the rubber slab, and around the setting of feed liquor macropore, there are four feed liquor aperture, institutes
The front for stating rubber slab is filters pressing face, and the front of rubber slab is evenly arranged with multiple support rims, between multiple support rims
Gap constitute flow-guiding channel, the back side of the rubber slab is provided with multiple boss, and the upper and lower part of the rubber slab is all provided with
It is equipped with deflector hole, the positive upper and lower part of the rubber slab is provided with diversion trench, and diversion trench is connected with deflector hole；
The back side outer rim of the rubber slab is provided with sealing ring, is provided with connection card on the external annulus and internal ring wall of the sealing ring
Slot.
A kind of the utility model filter press ethylene propylene diene rubber filter plate, the front and back of the rubber slab is in feed liquor
The flange of cyclic structure is arranged in the surrounding of macropore and feed liquor aperture, and the front or the back side of flange and rubber slab are arc transition
Connection.
Compared with prior art, the utility model has the beneficial effects that
The utility model is made by the way of rubber filter plate and the hardened conjunction of metal filtering core compared with conventional filter plate；Nothing
Runner processing need to be carried out on metal filtering core plate, so that processing is more convenient, weight is lighter；Simultaneously as filtrate expands
Enable rubber additionally to apply squeezing action to filter cake in extrusion process, its filter capacity is improved, so that its filters pressing
Better effect.Meanwhile using ethylene propylene diene rubber after so that filter plate have excellent resistance to corrosion, ageing-resistant and weatherability
Can, it can be used for a long time within the scope of -40 DEG C~+80 DEG C.

Specific embodiment
Referring to Fig. 1~4, the utility model relates to a kind of filter press ethylene propylene diene rubber filter plate, the filter plate includes
There is rubber slab 1, the material of the rubber slab 1 is ethylene propylene diene rubber, and the middle part of the rubber slab 1 is provided with feed liquor macropore 1.1,
Around the setting of feed liquor macropore 1.1, there are four feed liquor apertures 1.2, and the front of the rubber slab 1 is filters pressing face, and rubber slab 1 is just
Face is evenly arranged with multiple support rims 1.3, and the gap between multiple support rims 1.3 constitutes flow-guiding channel, the rubber slab 1
The back side be provided with multiple boss 1.4, the upper and lower part of the rubber slab 1 is provided with deflector hole 1.5, the rubber slab 1
Positive upper and lower part be provided with diversion trench 1.6, and diversion trench 1.6 is connected with deflector hole 1.5；The rubber slab 1
Back side outer rim be provided with sealing ring 2, be provided on the external annulus and internal ring wall of the sealing ring 2 connection card slot 2.1；
Further, the front and back of the rubber slab 1 is set in the surrounding of feed liquor macropore 1.1 and feed liquor aperture 1.2
The flange of cyclic structure is set, and flange is that arc transition is connect with the front of rubber slab 1 or the back side, plays the work for reinforcing connection
With；
In use, after rubber slab 1 is installed on the filter core plate of steel structure by the connection card slot 2.1 on sealing ring 2
Set loads onto filter cloth and (forms cavity between rubber slab 1 and filter core plate, boss 1.4 can prevent the plate face of rubber slab 1 and filter core plate from occurring
Being adhered influences the effect that cavity imports filtrate), filter frame composition filter chamber, and adjacent filter are provided between two pieces of filter plates being disposed adjacent
Support rim 1.3 between plate is correspondingly arranged, and then imports suspension by the deflector hole 1.5 being located above, suspension is being led
Enter filter chamber under the guidance of chute 1.6；Suspension forms filter cake in filter chamber, the runner that filtrate is constituted through support rim 1.3 by
Deflector hole 1.5 positioned at the guidance of diversion trench 1.6 to the lower section of bottom exports, and adjacent two blocks of rubber slabs 1 is then squeezed, in pressure
Under effect, filtrate sub-fraction is exported through deflector hole 1.5, and most of filtrate is under the effect of the pressure quickly through feed liquor macropore 1.1
(due to the presence of filter cloth, solid particle is cut in the cavity formed between the entrance rubber slab 1 of feed liquor aperture 1.2 and filter core plate
Stay), since rubber slab 1 is EPDM material and has elasticity, the filtrate entered in cavity will lead to expandable cavity, swollen
Swollen rubber slab 1 is pressed into filter frame and squeezes to the filter cake further progress in filter frame, isolates the filtrate in filter frame in filter cake, into
One step reduces the water content of filter cake；Improve separating effect.
In addition: it should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
