The utility model content
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of press filtration efficient is high, the press filtration effect is good, the chamber filter plate of long service life and provide.
The technical scheme of the utility model is achieved in that a kind of chamber filter plate; Comprise the filter cloth that is installed on the filter plate, with respect to the thickening of filter plate surface and around the filter plate edge, be provided with and embed the convexity that has on annular slot that filter cloth is arranged, the filter plate surface, be located at the lip-deep charging through hole of filter plate in filter plate edge near the filter plate surface; On the face at filter plate edge, being provided with and embedding has the annular groove of sealing with rubber strip, on the filter plate surface, is provided with vent.
In four angles of said filter plate, have at least an angle to offer through hole, offer the washing channel that is connected with the filter plate surface on the through-hole wall.
Described through hole is located between annular groove and the annular slot, and between through hole and annular slot, being provided with and embedding has the separate slot of sealing with rubber strip.
On the wall of said filter plate, have the filtrate hole of leading to the filter plate surface.
Described charging through hole is located at the centre of filter plate.
Described filter plate is processed with the RPP material.
The good effect of the utility model:
Annular groove is set on the face at the utility model filter plate edge and has embedded rubber strip, strengthened sealing, improved the press filtration effect of material; The vent that on the filter plate surface, is provided with has been avoided the formation pressure differential, causes bias voltage, thereby damages the phenomenon of filter plate, has improved press filtration efficient.

Specific embodiment
Embodiment 1: like Fig. 1,3, shown in 4; The utility model comprise the filter cloth 2 that is installed on the filter plate 1, with respect to 3 thickenings of filter plate surface and around filter plate edge 4, be provided with and embed the convexity 13 that has on annular slot 5 that filter cloth is arranged, the filter plate surface 3 at 4 places, filter plate edge, be located at the charging through hole 7 on the filter plate surface 3 near filter plate surface 3; On the face at filter plate edge 4, being provided with and embedding has the annular groove 8 of sealing with rubber strip, on filter plate surface 3, is provided with vent 9.
In four angles of filter plate 1, all be provided with through hole 6, two through holes on filter plate 1 top are the washing lotion hole, and two through holes of bottom are the undercurrent hole, form two two closed deliveries of washing, and offer the washing channel 10 that is connected with filter plate surface 3 on through hole 6 inwalls.
Described through hole 6 is located between annular groove 8 and the annular slot 5, and between through hole 6 and annular slot 5, being provided with and embedding has the separate slot 11 of sealing with rubber strip.
Described charging through hole 7 is located at the centre of filter plate, and filter cloth 2 is threaded to be buckled together mutually to compress through compress board or cushion rubber and is arranged on charging through hole edge.
Filter plate is processed with the RPP material.
During application this filter plate of polylith being arranged between pressure strip and the thrust plate, compressing then, is filter chamber between compacted filter plate and the filter plate; The material that is pumped into by material gets into each filter chamber from the thrust plate charging hole, and solid particle is trapped within the filter chamber, and forms filter cake; Filtrating then sees through filter cake and filter cloth and is discharged outside the body by two through holes of filter plate bottom then, when filter cake is washed, can feed washings through two through holes on filter plate top filter cake is washed; Washing lotion is discharged outside the body by two through holes of filter plate bottom then, when filter cake is dried up, can feed compressed air through two through holes on filter plate top; Filter cake is dried up; The filter cake that again extruding stem is formed is discharged, and carries out the press filtration of next time, and embedding has the rubber strip separate slot to have sealing to be used to seal each through hole with the annular groove of rubber strip with embedding.
Embodiment 2: like Fig. 2,3, shown in 4; The utility model comprise the filter cloth 2 that is installed on the filter plate 1, with respect to 3 thickenings of filter plate surface and around filter plate edge 4, be provided with and embed the convexity 13 that has on annular slot 5 that filter cloth is arranged, the filter plate surface 3 at 4 places, filter plate edge, be located at the charging through hole 7 on the filter plate surface 3 near filter plate surface 3; On the face at filter plate edge 4, being provided with and embedding has the annular groove 8 of sealing with rubber strip, on filter plate surface 3, is provided with vent 9.
