Description

A kind of press filtration unit of vertical full-automatic high-pressure filter
 
Technical field:
The present invention relates to a kind of press filtration unit, relate in particular to a kind of press filtration unit of vertical full-automatic high-pressure filter.
Background technology:
At present domestic and international existing various pressure filtering equipments (comprising the full-automatic vertical diaphragm filter press), the press filtration unit, be rectangle or square structure, and the mode that adopts the diaphragm of rubber pressurising to expand filter cake is pushed, this just caused its feed pressure (≤1MPa) and squeeze pressure (≤2MPa) lower, being applied to industries such as mine, metallurgy, pharmacy, is not that too poor, viscosity is not that very high material is implemented Separation of Solid and Liquid to water penetration, and filter effect is all right.But some material of industry such as chemical industry, food has high viscosity even hyperviscosity; The mud (moisture content is still not up to standard) that after preliminary treatment, forms of sanitary sewage or trade effluent for another example, the water penetration extreme difference.The press filtration unit of existing filtering equipment is very poor to the Separation of Solid and Liquid treatment effect of above-mentioned material, can be described as helpless.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple and practical, good filtration effect, cost is low, environmental protection, the press filtration unit of vertical full-automatic high-pressure filter applied widely.
Purpose of the present invention can reach by following measure: a kind of press filtration unit of vertical full-automatic high-pressure filter, it is characterized in that it comprises the press filtration piston, the press filtration cylinder sleeve, the press filtration piston is provided with Under The Grille, last grid, Under The Grille is provided with down filter cloth, following filter cloth connects the filter cloth roller, be provided with filter cloth below the last grid, the press filtration piston is provided with feed slurry inlet, filtrate (liquid, compressed air inlet, feed slurry inlet communicates with filter chamber, uniform several plunger cylinders of press filtration cylinder sleeve excircle, the oil pocket of plunger cylinder is communicated with by the press filtration cylinder sleeve, the plunger rod upper end of plunger cylinder connects with the press filtration piston, the press filtration cylinder sleeve is provided with oil inlet and outlet, and oil inlet and outlet connects plunger cylinder.
In order further to realize purpose of the present invention, described press filtration piston is provided with piston static seal circle and piston dynamic seal ring.
The present invention can produce following good effect compared with the prior art: (3.5～8MPa) height can be isolated the liquid component in the material to greatest extent for feed pressure of the present invention (can reach 2MPa) and squeeze pressure; " large tank " formula of employing structure, the similar short stroke of the structure of press filtration unit " large tank " is utilized " piston " squeezing, and no diaphragm of rubber (consumable accessory, cost is higher) has reduced operating cost significantly; Two-sided row's filtrate has avoided high sticking material after filter cloth forms one deck " film blocks water ", the situation that filter chamber top filtrate can't be discharged up and down.So, be specially adapted to the material of hyperviscosity, water penetration extreme difference, especially the second dehydration of domestic sludge and industrial sludge is handled, the moisture content of mud cake can be down to about 50% after the press filtration, for the terminal processes of mud provides unprecedented facility, and reduce processing cost greatly, will produce very positive progradation to environmental protection cause.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of two-layer press filtration unit press filtration state.
Embodiment: a kind of press filtration unit (referring to Fig. 1) of vertical full-automatic high-pressure filter, it comprises press filtration piston 1, press filtration cylinder sleeve 7.Press filtration piston 1 is provided with Under The Grille 15, goes up grid 9, Under The Grille 15 is provided with down filter cloth 12, following filter cloth 12 connects filter cloth roller 3, be provided with filter cloth 10 below the last grid 9, press filtration piston 1 is provided with feed slurry inlet 4, filtrate (liquid 13, compressed air inlet 11, and feed slurry inlet 4 communicates with filter chamber 2, uniform several plunger cylinders 6 of press filtration cylinder sleeve 7 excircles, the oil pocket of these plunger cylinders 6 is communicated with by press filtration cylinder sleeve 7, and the plunger rod upper end of plunger cylinder 6 connects with press filtration piston 1.Press filtration cylinder sleeve 7 is provided with oil inlet and outlet 5, and oil inlet and outlet 5 connects plunger cylinder 6.Press filtration piston 1 is provided with piston static seal circle 14 and piston dynamic seal ring 8.
During use, press filtration of the present invention unit is provided with one deck at least in vertical full-automatic high-pressure filter, form filter chamber between the following filtrate plate of press filtration unit and high-pressure filteration machine during one deck, two-layer when above, form filter chamber between the adjacent press filtration unit, form filter chamber between the following filtrate plate of orlop press filtration unit and high-pressure filteration machine.Filter cloth roller 3 links to each other with the hydraulic motor of the Hydraulic Station control of vertical full-automatic high-pressure filter, feed slurry inlet 4 links to each other with the feed hose of vertical full-automatic high-pressure filter, compressed air inlet 11 links to each other with the air induction hose of vertical full-automatic high-pressure filter, and filtrate (liquid 13 links to each other with the filtrate flexible pipe of vertical full-automatic high-pressure filter.Oil inlet and outlet 5 links to each other with the hydraulic hose of vertical full-automatic high-pressure filter.
Operation principle:
Plunger cylinder 6 action simultaneously under the driving of the Hydraulic Station of vertical full-automatic high-pressure filter of every lamination filter unit, reach pressurize after the range, it is descending that the main hydraulic cylinder of vertical full-automatic high-pressure filter drives each lamination filter unit, after closing up fully between each layer and with following filtrate plate, the main hydraulic cylinder upper cavity pressure reaches the back pressurize of (feed state) setting value.Form a filter chamber (see figure 2) between every adjacent two layers press filtration unit this moment, and piston static seal circle 14 and piston dynamic seal ring 8 have guaranteed the seal of filter chamber self.Squeeze into slip by feed slurry inlet 4 this moment in each metafiltration chamber, wherein most of liquid component passes through following filter cloth 12, Under The Grille 15 and goes up filter cloth 10, last grid 9, discharge (and concentrate through the filtrate flexible pipe of high-pressure filteration machine, main filtrate pipe) from filtrate (liquid 13, solid constituent in the slip then is trapped within each metafiltration chamber 2, forms by " filter cake ".After charging finished, main hydraulic cylinder continued descending (each layer plunger rod is pressed down, and plunger cylinder 6 pressure raise, above automatic overflow behind the oil pressure relief of setting), drives each lamination filter piston 1 and presses down, and squeezes out the liquid in the filter cake to greatest extent.Compressed air inlet 11 from each lamination filter piston 1 behind the squeezing certain hour feeds high pressure gas, the residual night of " extruding " filter chamber each " corner ".At this moment, filter cake reaches (in the possible range) maximum aridity.Main hydraulic cylinder goes upward to the top, and each lamination filter distance between cells reaches maximum, and each filter cloth roller 3 is transferred filter cloth 12 under the scrolling at the driving backspin of hydraulic motor, and filter cake is with filter cloth 12 discharges down.
