Background technology
CN201565171U, title " a kind of composite filter plate of vertical press filter ", it is characterized in that overall employing rectangular flat formula composite construction, the top of composite filter plate is barrier, be embedded in filter, middle part is gripper shoe, bottom is enclosing square frame, between gripper shoe and frame, barrier film is housed, and the bottom of frame is embedded with sealing ring.Its weak point: one is to realize directly laminating between filter plate and filter plate, and filter efficiency is low; Two is complex structures, and manufacturing cost is high; Three is that filter plate plate body intensity is low, very easily produces disrepair phenomenon; Four is that filter plate anti-wear performance is poor, filter cake haftplatte phenomenon is serious; Five is that material due to filter plate feed pathway and liquid outlet channel wall adhering to cannot thoroughly be removed in the industrial production at all, causes different material to stick on conduit wall, not only causes that to be squeezed filtrate impure, and causes in the filtrate that is squeezed containing germ.
Summary of the invention
Purpose of design: avoid the weak point in background technology, designs a kind of one side at filter plate and arranges filter chamber and filter plate plate body intensity is high, service life, filter efficiency are high, the vertical type blotter press membrane filter plate of sticky cake.
Design: in order to realize above-mentioned purpose of design.The present invention is in structural design: 1, filter plate one side has the design that mill room is filtered in single chamber, is one of technical characteristic of the present invention.The object done like this is: filter plate one side is designed to single chamber and filters mill room, another side (non-filtered mill room face) and be designed to extrude diversion chamber, it can not only make filter plate itself realize integrating filtration and diaphragm pressing, and under filter plate intensity prerequisite can be guaranteed, drastically increase squeeze and filter efficiency, the more important thing is the combination realizing out gravity and pump pressure and filter, make dewatering higher.2, filter plate lower surface is provided with fluid assembly and the design of the liquid outlet of fluid assembly liquid outlet channel design in the non-diaphragm plate face of filter plate, is technical characteristic two of the present invention.The object done like this is: the depth of groove due to the non-diaphragm plate face of filter plate is less than the depth of groove in the diaphragm plate face of filter plate, make the increase of filter plate plate body thickness, intensity enhancing, thus the filter plate plate body intensity solving background technology existence is low, the phenomenon of cracky.3, filter plate another side groove surface being equipped with the design of nanometer composite layer, is technical characteristic three of the present invention.The object done like this is: nano composite material is with resin, rubber, the matrixes such as pottery and metal are continuous phase, with the metal of nano-scale, semiconductor, rigid particles and other inorganic particulates, fiber, CNTs etc. are modified as decentralized photo, by suitable preparation method, modifier uniformity is scattered in matrix material, form the compound system that contains nano-sized materials mutually, therefore the application arranges composite layer at filter plate another side groove surface, it not only has the characteristic of not viscosity, and effectively can improve the intensity of attaching substrates, after nanometer composite layer is combined with filter plate face, effectively can not only improve the wearability on filter plate surface, and the service life of filter plate is improved widely.4, the feed pathway wall of filter plate and liquid outlet channel wall are equipped with the design of nanometer composite layer, are technical characteristics four of the present invention.The object done like this is: the feed pathway wall of plate and liquid outlet channel wall are because diameter is little, passage is curve type, cannot reach aborning at all and remove thoroughly, the different material be squeezed is caused to stick on the wall of passage, hydraulic pressure rinses and cannot rinse well at all, not only cause that to be squeezed liquid impure, and the germ grown directly has influence on the quality being squeezed liquid, become this area insurmountable technical barrier for a long time.The application is by being equipped with nanometer composite layer at feed pathway wall and liquid outlet channel wall, and nanometer composite layer has superpower not viscosity, it can make the material passed through not stick on wall, and can under the effect of current overcurrent, remove clean easily, the more important thing is because nano TiO 2/PP composite material has excellent antibacterial effect, its TiO_2 nanoparticles disperses to reach 60nm in polypropylene, therefore the nanometer composite layer that the application puts has excellent antibacterial effect, solves this area unsolved technical barrier for a long time.
Technical scheme: a kind of vertical type blotter press membrane filter plate, comprises filter plate, described filter plate one side has single chamber and filters mill room, and diaphragm plate is positioned on mill room and diaphragm plate surrounding and filter plate face of filtering, single chamber and is sealed and matched.
The present invention is compared with background technology, and one is achieve directly laminating between filter plate and filter plate, and filter efficiency is low; Two is that structure is simple, low cost of manufacture; Three is that filter plate plate body intensity is high, disrepair phenomenon can not occur, long service life; Four is that filter plate anti-wear performance is good, achieves filter cake not haftplatte; Five is fundamentally solve the material phenomenon that this area for a long time filter plate feed pathway and liquid outlet channel wall adheres to, and ensure that the purity being squeezed filtrate, and has greatly saved the water resource for cleaning filter plate.
