Description

Tension formula filter press

Technical field

The utility model relates to a kind of solid-liquid separating equipment, refers in particular to the tension formula filter press that suspension is 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 its surperficial filter cloth constitutes to form; Corollary system is made up of hydraulic power unit, feed 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 feed 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 that traditional filter press self structure design aspect exists 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) plate pulling device is a chain gearing structure, adopts and to draw back the discharging of filter plate mode one by one, and noise is big, poor reliability, 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 tension formula filter press, this machine adopts tension mode to compress filter element, mode quickly discharging material and fixing, a brand new form that moves the two ends enter material way design of two feeding mouths while pan feeding are drawn back in the filter plate grouping for four times, 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, filter element, pressure strip, take-up device and plate pulling device, and support wherein, thrust plate, two back timbers and end frame constitute a frame structure frame with bolt connecting mode; Arrange filter element and pressure strip successively on the inboard back timber of thrust plate, filter element comprises an intermediate plate, a connecting plate, several piece filter plate and be layed in its surperficial filter cloth, whole filter plates wherein and to be layed in its surperficial filter cloth be that the boundary is divided into different three groups of quantity with intermediate plate and connecting plate respectively, filter plate between thrust plate and intermediate plate and to be layed in its surperficial filter cloth be first group, filter plate between intermediate plate and connecting plate and to be layed in its surperficial filter cloth be second group, filter plate between connecting plate and pressure strip and to be layed in its surperficial filter cloth be the 3rd group, first group of quantity and the 3rd group of quantity are all the N piece, second group of quantity is the 2N+1 piece, thrust plate, filter plate, intermediate plate, filter plate, connecting plate, filter plate links to each other by endless chain successively with pressure strip, filter plate, intermediate plate, connecting plate and pressure strip pass through its roller hanger suspending separately again on back timber; Two main hydraulic cylinder symmetries are installed in both sides, thrust plate middle part, its piston rod respectively with the hinged formation take-up device in pressure strip both sides, middle part; Two arm-tie hydraulic cylinder symmetries are installed in both sides, intermediate plate top, and one end piston rod is hinged with both sides, thrust plate top respectively, other end piston rod respectively with the hinged formation plate pulling device in both sides, connecting plate top; The thrust plate middle part is provided with a fixedly feeding mouth, and the pressure strip middle part is provided with a mobile feeding mouth, and two feeding mouths are pan feeding simultaneously, fixedly a kind of two ends of the common one-tenth of feeding mouth and mobile feeding mouth structure enter material way.Its operation principle is, take-up device at first spurs pressure strip and closes up and compress filter element, open supporting feed pump with two ends enter material way pan feeding, treat that whole filter chambers are full of by filter cake, during the suspension filtered EO, when take-up device unclamps pressure strip and moves to assigned address, pressure strip draws back the discharging of the 3rd group of N piece filter plate successively by endless chain, when plate pulling device closes up the 3rd group of filter plate along equidirectional promotion connecting plate, connecting plate draws back the N piece filter plate discharging that is adjacent in second group of filter plate successively by endless chain, plate pulling device promotes intermediate plate along equidirectional again and closes up when being drawn back filter plate in second group, intermediate plate draws back the discharging of first group of N piece filter plate successively by endless chain, when last plate pulling device spurs intermediate plate in the other direction and closes up first group of filter plate, intermediate plate draws back the other N piece filter plate discharging that is adjacent in second group of filter plate more successively by endless chain, and so far a working cycles finishes.

The beneficial effects of the utility model are: because of the tension mode that has adopted the tension 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, can when improving whole aircraft reliability, reduce complete machine weight; Adopt that filter plate is divided into three groups packet design in the filter element, draw back whole filter plate dischargings four times, both can guarantee to have between filter plate and reasonably unload material space, exceed again when increasing the machine shape length dimension, improved plate pulling efficiency, shortened the discharge time; Plate pulling device adopts hydraulic drive, and noise is little, reliability is high; Adopt the two ends enter material way, can improve pan feeding speed, shorten filtration time, can improve each filter chamber pan feeding uniformity again, reduce the pressure reduction of filter plate both sides, reduce the filter plate breakage rate.
