Description

A kind of press filtration unit of vertical type full automatic high-pressure filteration machine
Technical field:
The utility model relates to a kind of press filtration unit, relates in particular to a kind of press filtration unit of vertical type full automatic high-pressure filteration machine.
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 the 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 the industry such as chemical industry, food, have even hyperviscosity of high viscosity; The mud (moisture content is still not up to standard) that forms after pretreatment 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.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of simple and practical, good filtration effect, and cost is low, environmental protection, the press filtration unit of vertical type full automatic high-pressure filteration machine applied widely.
the purpose of this utility model can reach by following measure: a kind of press filtration unit of vertical type full automatic high-pressure filteration machine, 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, upper grid, Under The Grille is provided with lower filter cloth, lower filter cloth connects the filter cloth roller, below upper grid, be provided with filter cloth, 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, oil inlet and outlet connects plunger cylinder.
In order further to realize the purpose of this utility model, described press filtration piston is provided with piston static sealing ring and piston dynamic seal ring.
The utility model can produce following good effect compared with the prior art: (3.5～8MPa) height, can isolate the liquid component in material to greatest extent for feed pressure of the present utility model (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 ", utilize " piston " squeezing, without diaphragm of rubber (consumable accessory, cost is higher), reduced significantly operating cost; The two-sided row's filtrate in up and down, avoided high sticky material after on filter cloth, forming one deck " film blocks water ", the situation that filter chamber top filtrate can't be discharged.So, be specially adapted to the material of hyperviscosity, water penetration extreme difference, especially the second dehydration of domestic sludge and industrial sludge is processed, after press filtration, the moisture content of mud cake can be down to 50% left and right, for the terminal processes of mud provides unprecedented facility, and greatly reduce processing cost, to environmental protection cause, will produce very positive progradation.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
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 type full automatic high-pressure filteration machine, it comprises press filtration piston 1, press filtration cylinder sleeve 7.Press filtration piston 1 is provided with Under The Grille 15, upper grid 9, Under The Grille 15 is provided with lower filter cloth 12, lower filter cloth 12 connects filter cloth roller 3, below upper grid 9, be provided with filter cloth 10, 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 sealing ring 14 and piston dynamic seal ring 8.
During use, press filtration of the present utility model unit is provided with one deck at least in vertical type full automatic high-pressure filteration machine, during one deck, between the lower filtrate plate of press filtration unit and high-pressure filteration machine, form filter chamber, two-layer when above, between adjacent press filtration unit, form filter chamber, between the lower filtrate plate of orlop press filtration unit and high-pressure filteration machine, form filter chamber.Filter cloth roller 3 is connected with the hydraulic motor that the Hydraulic Station of vertical type full automatic high-pressure filteration machine is controlled, feed slurry inlet 4 is connected with the feed hose of vertical type full automatic high-pressure filteration machine, compressed air inlet 11 is connected with the air induction hose of vertical type full automatic high-pressure filteration machine, and filtrate (liquid 13 is connected with the filtrate flexible pipe of vertical type full automatic high-pressure filteration machine.Oil inlet and outlet 5 is connected with the hydraulic hose of vertical type full automatic high-pressure filteration machine.
Operation principle:
Plunger cylinder 6 action simultaneously under the driving of the Hydraulic Station of vertical type full automatic high-pressure filteration machine of every lamination filter unit, reach pressurize after range, it is descending that the main hydraulic cylinder of vertical type full automatic high-pressure filteration machine drives each lamination filter unit, after between each layer and with lower filtrate plate, closing up fully, the main hydraulic cylinder upper cavity pressure reaches the rear 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 sealing ring 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 is by lower filter cloth 12, Under The Grille 15 and upper filter cloth 10, upper grid 9, from filtrate (liquid 13, discharge (and concentrating through the filtrate flexible pipe of high-pressure filteration machine, main filtrate pipe), solid constituent in slip is trapped within each metafiltration chamber 2, forms by " filter cake ".After charging was complete, main hydraulic cylinder continued descending (each layer plunger rod is pressed down, and plunger cylinder 6 pressure raise, over automatic overflow after the oil pressure relief of setting), drives each lamination filter piston 1 and presses down, and squeezes out to greatest extent the liquid in filter cake.After the squeezing certain hour, from the compressed air inlet 11 of each lamination filter piston 1, pass into high pressure gas, the residual night of " extruding " filter chamber each " corner ".At this moment, filter cake reaches (in possible range) maximum aridity.Main hydraulic cylinder goes upward to top, and the distance between each lamination filter unit reaches maximum, and each filter cloth roller 3 is transferred filter cloth 12 under scrolling at the driving backspin of hydraulic motor, and filter cake is discharged with lower filter cloth 12.
