Description
Technical field
The present invention relates to a kind of solid-liquid separating equipment, the compound tension-type pressure that processing is filtered to suspension is referred in particular to
Filter.
Background technique
Currently, traditional filter press is the rack being made of thrust plate, girder, compression or tension device, it is placed in rack master
The filter element composition that pressure plate, several piece filter plate on beam and the filter cloth for being layed in its surface are constituted.When filter press works, compress
Or tension device pushes or pull on pressure plate first and filter element is pressed between pressure plate and thrust plate, makes filter element shape
At the filter chamber of several good seals, then suspension to be filtered is passed through by matched feed pump and is connected with thrust plate feeding inlet
Pipeline is pressed into filter chamber, and the liquid phase in suspension passes through filter cloth and forms filtrate, and filter element is discharged through the filtrate channel on filter plate,
Solid phase in suspension is trapped in filter chamber by filter cloth forms filter cake, so that the liquid phase in suspension be made to separate with solid phase, completes
To the filtration treatment of suspension.When whole filter chambers are full of by filter cake, after suspension filter operation, compress or tension device is loose
Pressure plate is opened, automatically one by one pulls open filter plate either manually or by plate pulling device, filter cake is de- from open filter chamber under the effect of gravity
It falls, whole filter chamber dischargings terminate the completion of the latter working cycles.
In the filter press course of work, the inherent shortcoming as existing in terms of traditional filter press structural design causes
There are following wretched insufficiencies for it:
(1) sealing of filter element uses compression mode, the girder in rack should bear filter element own wt and
The gravity that filter cake weight generates bears the huge pulling force generated when compressing filter element again, and girder is under combined stress effect
Easily buckling deformation；Meet the rigidity and intensity requirement of girder, improves whole aircraft reliability, the section ruler for the girder to be increased that is bound to
It is very little, directly result in the increase of main screw lift and manufacturing cost.
(2) sealing of filter element uses tension mode, although the girder in rack is not bearing combined stress, from essence
On improve the force-bearing situation of rack, but the forced area for tensing piston in hydraulic cylinder rod chamber is small, to generate and compression mode
Identical pressing force, it is necessary to increase the cylinder diameter of hydraulic cylinder or improve the operating pressure of hydraulic system, increase the cylinder diameter of hydraulic cylinder
The increase for leading to main screw lift and manufacturing cost, the operating pressure for improving hydraulic system had not only increased manufacturing cost but also reduced complete machine can
By property.
Summary of the invention
In order to overcome traditional filter press deficiency described in the background, the present invention provides a kind of compound tension-type filters pressing
Machine, the machine using tense with hold out against combine by the way of compress filter element, well solved traditional compression type and tension-type
Inherent shortcoming existing in terms of filter press structural design.
The technical solution adopted by the present invention to solve the technical problems is: the filter press is by rack, filter element, compression
Plate, mobile holding device and tension device composition.Rack therein includes thrust plate, two top beams, two foundation beams and holds bracket,
Top beam and bottom beam are respectively symmetrically mounted on thrust plate and hold the top and two sides of the bottom of bracket, they are constituted with bolt connecting mode
The rack of one frame structure；Filter element, pressure plate and movement are sequentially arranged on two top beams of thrust plate two sides in rack
Holding device, filter element, pressure plate and mobile holding device are by its respective idler wheel hanger suspending on two foundation beams；It moves
Dynamic holding device includes holding out against bracket and holding out against hydraulic cylinder, holds out against hydraulic cylinder and is mounted on and holds out against on bracket, piston rod and is compressed
Connection in the middle part of plate；Tension device includes that two or four tenses hydraulic cylinder, tenses the two sides that hydraulic cylinder is symmetrically mounted on thrust plate,
Their piston rod respectively with hold out against bracket both ends and connect.Its working principle is that tension device is first by two tension hydraulic cylinders
Mobile holding device and pressure plate are first pulled, filter element, movable top while locking tenses hydraulic cylinder are closed up and once compress
Tight device holds out against pressure plate again by holding out against hydraulic cylinder with bigger pressure, and secondary compression filter element simultaneously starts filtering behaviour
Make, mobile holding device once unclamps pressure plate first after filtering, the then secondary release pressure plate of tension device and movement
Start discharging to designated position, so far a working cycles terminate.
The beneficial effects of the present invention are: compressing filter element because using compound tension mode, traditional tension-type is inherited
Filter press girder is not subject to the advantages of combined stress, while is overcome again because tensing piston forced area in hydraulic cylinder rod chamber
It is small, it is necessary to the shortcomings that increasing cylinder diameter or improving line pressure, it can be while reducing complete machine manufacturing cost, significantly
Improve whole aircraft reliability.
