Description
Technical field
The utility model relates to a kind of solid-liquid separating equipment, refers in particular to the two tension rapid pressure filters that suspension carried out filtration treatment.
Background technology
At present, traditional filter press is by thrust plate, girder, compresses and frame that plate pulling device constitutes, places pressure strip, the several piece filter plate on the frame main beam and be layed in the filter element that the filter cloth on filter plate surface constitutes to form; Corollary system is made up of hydraulic power unit, pan feeding pump, peripheral connecting line and electrical apparatus control system.During filter press work, hold down gag at first promotes pressure strip filter element is pressed between pressure strip and the thrust plate, make filter element form the filter chamber of several good seals, by the pan feeding pump suspension to be filtered pipeline through linking to each other with the thrust plate feeding mouth is pressed in the filter chamber then, liquid phase in the suspension is passed filter cloth and is formed filtrate, and the filtrate channel on filter plate is discharged filter element; Solid phase in the suspension is trapped in by filter cloth and forms filter cake in the filter chamber, thereby the liquid phase in the suspension is separated with solid phase, finishes the filtration treatment to suspension.Treat that whole filter chambers are full of by filter cake, behind the suspension filtered EO, hold down gag unclamps pressure strip, and plate pulling device draws back filter plate one by one, and filter cake comes off from the filter chamber that opens wide under the gravity effect, and whole filter chamber dischargings finish a back working cycles and finish.
In the filter press course of work, because the inherent shortcoming of traditional filter press self structure design aspect causes it to have following wretched insufficiency:
(1) sealing of filter element is adopted and to be compressed mode, causes frame stressed unreasonable, especially at gravity that filter element own wt and filter cake weight produce and compress girder buckling deformation very easily under the huge pulling force double action that filter element produces; Satisfy the rigidity and the requirement of strength of frame, improve whole aircraft reliability, certainly will will increase the sectional dimension of the overall dimensions and the girder of frame, directly cause the increase of complete machine weight and manufacturing cost.
(2) filter plate adopts and draws back mode one by one, and efficient is low, speed is slow, causes the discharge time long.
(3) pan feeding adopts the single feeding mouth enter material way of thrust plate, and each filter chamber pan feeding lack of homogeneity, speed are slow, causes filter plate breakage rate height, filtration time long.
The utility model content
In order to overcome traditional filter press not enough described in the background technology, the utility model provides a kind of two tension rapid pressure filter, this filter press adopts that two filter element symmetric arrangement, the pressure strip of symmetry tension simultaneously compress in the filter element, the filter plate grouping is drawn back quickly discharging material for twice and the center fixed three feeding mouths brand new form of the three end enter material way design of pan feeding is simultaneously moved at two ends in the filter element, has solved the inherent shortcoming that traditional filter press self structure design aspect exists well.
The technical scheme that its technical problem that solves the utility model adopts is: this filter press is made up of frame, two filter elements, two pressure strips, take-up device and plate pulling devices.Wherein, frame comprises two end supports, intermediate plate, two back timbers and two foundation beams, back timber and bottom girder with bolt connecting mode respectively symmetry be installed in the top and the two bottom sides of end support and intermediate plate, constitute frame structure frame with the intermediate plate symmetry; Intermediate plate both sides difference is filter element of symmetric arrangement and a pressure strip successively, each filter element is made of identical several piece filter plate of a middle filter plate, middle filter plate both sides quantity and the filter cloth that is layed in the filter plate surface, several piece filter plate between pressure strip and the middle filter plate is first group of filter plate, several piece filter plate between middle filter plate and the intermediate plate is second group of filter plate, filter plate in the filter element, middle filter plate and pressure strip link to each other by hinge successively, and filter plate, middle filter plate and pressure strip pass through its roller hanger suspending separately again on back timber; Four double piston-rod tension hydraulic cylinders are with symmetrical respectively top and the bottom that is installed in the intermediate plate both sides of bolt connecting mode, and the piston rod at their two ends is hinged with the pressure strip at two ends, intermediate plate double-side filtering unit respectively, constitutes a complete take-up device; Two double piston-rod discharging hydraulic cylinders with bolt connecting mode respectively symmetry be installed in the middle part of two back timbers, the piston rod at their two ends respectively with intermediate plate double-side filtering unit in middle filter plate hinged, constitute a complete plate pulling device; Intermediate plate one middle side part is provided with a fixedly feeding mouth, and the outer middle side part of pressure strip is provided with a mobile feeding mouth, and fixedly feeding mouth is common constitutes a kind of two ends and move three feeding mouths of center fixed, three end enter material way of pan feeding simultaneously for two mobile feeding mouths and one.Its operation principle is, the tension system pressure strip at two ends, symmetrical pull intermediate plate double-side filtering unit at first simultaneously closes up second group of filter plate, mode with the filter element of symmetry tension simultaneously two ends pressure strip compresses filter element then, between filter plate and filter plate, form the filter chamber of good seal, open supporting pan feeding pump with three end enter material way pan feedings, treat that whole filter chambers are full of by filter cake, during the suspension filtered EO, tension system is loose ends pressure strip and when moving to assigned address simultaneously, pressure strip draws back first group of filter plate discharging by hinge symmetry successively, when first group of filter plate closes up along equidirectional promotion middle filter plate again in last arm-tie system, middle filter plate draws back second group of filter plate discharging by hinge symmetry successively, and so far a working cycles finishes.
The beneficial effects of the utility model are, because of having adopted two filter element symmetric arrangement, mode with the filter element of symmetry tension simultaneously two ends pressure strip compresses filter element, make relevant beam no longer bear huge pulling force, only bear the gravity that filter element own wt and filter cake weight produce, from having improved the force-bearing situation of filter press frame in essence, when improving whole aircraft reliability, reduce complete machine weight; Adopt that filter plate is divided into two groups packet design in each filter element, once symmetrical simultaneously two groups of filter plates that draw back in the intermediate plate double-side filtering unit, all the filter plate grouping is drawn back the mode discharging twice, can guarantee is having between filter plate on the basis of rationally unloading material space, exceed when increasing the machine shape length dimension, improve arm-tie speed and efficient, shorten the discharge time; Adopt three end enter material way, can improve pan feeding speed, shorten filtration time, can significantly improve each filter chamber pan feeding uniformity again, when reducing filter plate both sides pressure reduction, reduce the filter plate breakage rate.
