Description
Technical field
The utility model relates to a kind of plate and frame filter press, belongs to the solid-liquid separating equipment technical field.
Background technology
Plate and frame filter press is a kind of intermittent solid-liquid separating equipment, has characteristics such as light and handy, flexible, reliable, is to be arranged by filter plate, filter frame to constitute filter chamber, under the effect of dehvery pump, feed liquid is delivered to each filter chamber, by filter medium, with solid and fluid separation applications.Plate and frame filter press is compared other solid-liquid separating equipments such as centrifuge, has reduced investment, economize on electricity, and advantages such as safety are widely used in the sewage disposal of chemical industry, dyestuff, oil, pottery, medicine, food, smelting and all trades and professions etc.The mode that compresses of filter press has manually and compresses (small dimension), mechanical compaction and hydraulic pressure and compress three kinds of forms.Manually compress is that screw-jack promotion pressure strip compresses; Mechanical compaction is that motor is joined H type reduction box, promotes pressure strip through the frame drive disk assembly and compresses; It is to have the hydraulic cylinder parts of Hydraulic Station on frame to promote pressure strip to compress that hydraulic pressure compresses.Two crossbeams are thrust plate and the hold down gag formation frame that connects together, pressure strip and hold down gag are hinged on the frame, are being arranged in order filter plate (porose or atresia) between thrust plate and pressure strip, and a plate and thrust plate match, laminate and pressure strip match, and filter plate two sealing surfaces clip filter medium; Hold down gag promotes pressure strip, and all filter plates are pressed in the frame, reach specified thrust after, can filter.Suspension enters each filter chamber (space between the adjacent filter plate) from the charging hole on the thrust plate, and solid particle is filtered medium and is trapped in the filter chamber, and filtering then sees through medium, by going out to decide outside the hole discharge machine.It all is that the hydraulic cylinder parts of Hydraulic Station on frame compress filter plate towards a direction promotion pressure strip that existing hydraulic pressure compresses, because the hydraulic cylinder parts are to promote to compress filter plate towards a direction, lower, the same energy consumption of binder output causes energy waste easily.
For improving the press filtration effect, water content after the reduction press filtration, increase work efficiency, present filter press is provided with spring mechanism between mainboard and secondary frame, yet, the use of spring mechanism makes this patent have following shortcoming: 1) spring mechanism is arranged between mainboard and the secondary frame, mainboard and secondary frame to both sides produce tension force, the too much use of spring, resistance is big in the press filtration compaction process, the hydraulic compressing device workload is strengthened, efficient reduces, one time the press filtration material is less, 2) because the difference of each spring tension, can not keep the sheet frame balance to advance in the pressure-filtering process, error is big, moisture percentage in sewage sludge is higher after making sheet frame distortion and press filtration easily, 3) spring is along with the increase of access times, permanent deformation can take place in spring mechanism, if the spring generation deformation of mainboard and a certain position of secondary frame, in pressure-filtering process, the hydraulic cylinder parts promote pressure strip sheet frame are pushed, the deformation of spring causes mainboard and secondary frame all angles discontinuity, cause sheet frame distortion easily, when serious in addition material reveal, can't operate as normal, according to practical production experience, need just change spring every a period of time, but spring is arranged between mainboard and the secondary frame, changing spring needs the sheet frame device is all dismantled, the replacing difficulty is big, the maintenance cost height.
Chinese patent CN102728114A discloses a kind of hydraulic variable chamber filter press sheet frame, comprise base plate and frame, described sheet frame integral body is that frame protrudes, the inner recess structure, described base plate is arranged at a side of frame, and described frame is provided with charging aperture, and its opposite side is provided with movably push pedal, be provided with hydraulic cylinder between described base plate and the push pedal, described push pedal is connected with hydraulic cylinder.Described hydraulic variable chamber filter press plate mount structure is simple, be easy to realize, it adopts the cast iron structure, can bear immense pressure and indeformable, extremely strong sealing load can be provided, feed pressure can reach 1.6MPa-2MPa, inner squeezing can provide the strength of the squeezing about 4MPa, and the material water ratio after the dehydration reaches about 50%, has reduced the disposal cost in mud later stage significantly.But the oil cylinder of this patent directly acts on push pedal, causes the push pedal distortion easily, and the use of oil cylinder causes in the pressure-filtering process, and poorly sealed reality between sheet frame and the sheet frame is leaked material easily.
Because in filter process, a part is thin, the clay material can be attached in the middle of filter cloth surface or the filter opening, needs filter cloth is cleaned after scraper etc. is unsnatched filter cake, to guarantee the good air permeability of filter cloth, improves filter efficiency.Existing filter cloth cleaning device complex structure, equipment investment height, complex operation.
Chinese patent CN102921679A discloses the self-driven cleaning device of filter cloth cleaning machine, comprises the wiper mechanism and the PLC flow governor that place on the housiung separator, also is provided with to make the walking mechanism of wiper mechanism move left and right on the housiung separator; The control that wiper mechanism, walking mechanism are connected with the PLC flow governor respectively and all are subjected to.Wiper mechanism is connected on the walking mechanism by elevating mechanism, and elevating mechanism is the cylinder combining structure that links to each other with the PLC flow governor.The self-driven cleaning device of this filter cloth cleaning machine has not only adopted stable truss structure, and adopts the PLC control system, and it accomplishes that a key presses machine-electricity-liquid-gas organic connections together, works automatically, thereby has saved manpower, has improved operating efficiency.But complex structure, cost height, complex operation.
