Quick-opening press filter
Technical field
The utility model relates to a kind of solid-liquid separating equipment, refers in particular to the quick-opening press filter that suspension is carried out filtration treatment.
Background technology
At present, traditional filter press is the frame that is made of thrust plate, girder, hold down gag and plate pulling device, 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 adopts single hydraulic cylinder to compress mode, continuous increase along with present filter press filter area and filter plate size, the necessary corresponding increase of hydraulic cylinder cylinder diameter, stroke and hydraulic system pressure, satisfy the rigidity and the requirement of strength of pressure strip and hydraulic cylinder seat, certainly will to increase the overall dimensions 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 quick-opening press filter, this filter press adopt mobile thrust plate, one main four auxilliary five little cylinder diameter short stroke oil cylinders compress mode seal filter element, two mobile feeding mouths simultaneously in the both-end enter material way of pan feedings and the filter element filter plate grouping draw back the brand new form of discharging design for three times fast, solved the inherent shortcoming that traditional filter press self structure design aspect exists well.
