Abstract
The invention relates to a multi-cylinder pressure system used in filters and a pressure method thereof. A plurality of plunger cylinders and piston cylinders are fixed on the permanent seats of the cylinders at the same time, the plunger top surfaces of a plurality of plunger cylinders thereof and the piston head faces of the piston cylinders are connected with the pressure strip respectively, a pump oil cavity in the piston cylinder is communicated with a hydraulic pressure control device, and a plurality of plunger cylinders are communicated with the pump oil cavities of the piston cylinder. The invention has the advantages: firstly, the problems of manufacture difficulty and high cost of cylinders with large diameters in the background technology are solved; secondly, an active cylinder only has a small cylinder, thus leading to not only fast pressing speed but also little time spent.
Description
Technical field
The present invention relates to a kind of heavy wool cylinder pressing system and compressing method that is used for filter press, belong to filter press pressing system and compressing method and make the field.
Background technology
Existing filter press pressing system is single oil cylinder compressing structure, promptly adopts a piston oil-cylinder that the pressure strip of filter press is compressed.Its weak point: the one, served as (pressure) filter pressure when higher, can only adopt the piston oil-cylinder that strengthens cylinder diameter to obtain bigger thrust, and large diameter piston oil-cylinder not only has very high requirement to manufacturing process and material, and it is very high to make manufacturing cost, particularly for requiring the very big filter press of compaction pressure, this super-huge piston oil lacks not to be produced as yet, directly has influence on the production of large-scale filter press; The 2nd, it is slow to compress rapid-result degree, and the time is long.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of can plunger oil lack and piston oil-cylinder can either be realized big thrust filter press pressure strip, have the short heavy wool cylinder pressing system and the compressing method that are used for filter press of fast time of speed again.
Design: in order to realize above-mentioned purpose of design.On structural design: a plurality of plunger cylinders be fixed on the oil cylinder holder simultaneously with piston oil-cylinder (actuating cylinder) and a plurality of plunger cylinder and piston oil-cylinder in plunger be connected with the filter press pressure strip respectively with piston, be one of feature of the present invention.The purpose of doing like this is: the one, can be big with little generation, and can satisfy the demand that the desired big pressure of press filtration compresses the filter press pressure strip, and low cost of manufacture; The 2nd, because the power that acts on the filter press pressure strip is even, has therefore improved pressure strip the direct effect of filter plate assembly has been renderd a service, improved the squeezing efficient of filter plate; The 3rd, a plurality of plunger cylinders and piston oil-cylinder are fixed on the oil cylinder holder simultaneously, not only are convenient to install, and have guaranteed the synchronism of its work.2, the oil pumping chamber in the piston oil-cylinder is communicated with hydraulic control device, and a plurality of plunger cylinders 1 are communicated with the oil pumping chamber of piston oil-cylinder respectively, is two of feature of the present invention.The purpose of doing like this is: because actuating cylinder has only one--all by suction effect oil-feed, it is fast so not only to compress speed for all the other plunger cylinders of-piston oil-cylinder, and the time spent is few.When compressing, piston oil-cylinder stretches out when compressing the filter press pressure strip, in the piston oil-cylinder both sides or plunger cylinder all around dragged and stretched out together and compressed the filter press pressure strip; During backhaul, piston oil-cylinder is return, and the both sides plunger cylinder is dragged together to be return.
Technical scheme 1: the heavy wool cylinder pressing system that is used for filter press, a plurality of plunger cylinders and piston oil-cylinder are fixed on the oil cylinder holder simultaneously, the plunger end face of its a plurality of plunger cylinders and the piston end surface of piston oil-cylinder are connected with pressure strip respectively, oil pumping chamber in the piston oil-cylinder is communicated with hydraulic control device, and a plurality of plunger cylinders are communicated with the oil pumping chamber of piston oil-cylinder respectively.
Technical scheme 2: the compressing method that is used for the heavy wool cylinder pressing system of filter press, when compressing, piston in the piston oil-cylinder stretches out, compresses pressure strip, be positioned at piston oil-cylinder both sides or plunger cylinder all around under the drive of pressure strip, the compacted plate of plunger in its plunger cylinder drags together with piston oil-cylinder and stretches out when compressing vacuum oil suction in the oil pumping chamber of plunger cylinder from piston oil-cylinder; During backhaul, piston oil-cylinder is return, both sides or all around plunger cylinder 1 dragged together by piston oil-cylinder and return.
The present invention compares with background technology, and the one, solved the manufacturing difficulty and the high problem of cost of major diameter oil cylinder in the background technology; The 2nd, because actuating cylinder has only a little oil cylinder, it is fast not only to compress speed, and the time spent is few.
