Description
Technical field
The invention belongs to solution filter plant technical field, especially a kind of full-automatic back washing filter.
Background technology
It is presently used in high temperature, high pressure, high-viscosity material (such as plastic cement industry) filtration core and is rolled over using multiple layer metal silk screen
It is assemblied on the skeleton of an antipriming pipe after folded extrusion process shaping, then Jing multiple working procedures are made.The structure one side energy
It is enough to maximize developed area, the maximum extension filtration time under same big volume, and with good resistance to pressure.But
As filter gradually develops toward full-automatic direction, the anti-cleaning of defecator is increasingly subject to pay attention to.And the drainage screen of the device
Pleated structure causes impurity to enter rear it is difficult to cleaning, the generally calcination method of employing are easily burnt out at drainage screen, and fold again
Drainage screen easily squeezes bad, easily affects filtering accuracy；Simultaneously the consumable accessory cost is high, and production cost is big.
Emphasis is how to strengthen filtering accuracy in prior art, and can be carried out while filtering accuracy is ensured anti-
The defecator of cleaning is less.As disclosed a kind of hollow filtering table and using the stacked of the filtering table within 05 18th, 2011
Filter (Authorization Notice No.：The U of CN 201832471), the hollow filtering table includes two ring-shaped discs with filter opening and one
The ring skeleton of size and shape internal hollow out with matching, the inner band pod apertures of ring skeleton, the ring-shaped discs
Compression is removably attached to be sealed to form on two anchor rings of the ring skeleton and in contact position, two ring-shaped discs and ring
A storage cavity is formed between shape skeleton.The patent improves for filtering accuracy, but the device is in high pressure shape
When under state, when material enters storage cavity, the impulsive force of material is directly extruded to the drainage screen of both sides, needs the drainage screen of high withstand voltage
It is relatively costly to avoid damaging；Simultaneously in anti-cleaning process, the material of purification is by the circumferentially distributed pod apertures of ring-shaped discs
Outwards spray, generation makes the detached active force of two drainage screens, easily cause coming off for drainage screen, affect the use of product.
Also such as Chinese patent, CN201521058339.3 discloses a kind of disc shaped cascading type filter, although it can
Anti- cleaning is realized, however it is necessary that the cleaning for reversely realizing drainage screen for passing through inlet and outlet, it is impossible to realize Full-automatic filter net
Cleaning.

Liquid to be filtered by the filtrate import 201, in the piston cylinder 4, then on piston cylinder 4 described in Jing
Circular hole is entered in filter chamber 605, through the filtration of the filter assemblies 6, into rear chamber 604 is filtered, finally in filter chamber 101
Filtrate outlet 102 is converged to, realizes filtering solution.When drainage screen 603 needs cleaning, by the movement piston component
5 position, the liquid outlet 503 on piston is connected with the circular hole on the piston cylinder 4, and the solution after filtration can be in pressure
Under effect, by the filtration rear chamber 604 through the filter assemblies 6, into the filter chamber 605, will filter on filter assemblies 6
Impurity peel off from filter assemblies 6, through circular hole and liquid outlet 503, in filtering rod, and final arrange from filter
Go out, complete the cleaning to filter assemblies 6.The mistake in other filter chambers 605 is not affected during cleaning on filter assemblies 6
Filter, without inverted running filter, realizes the automatic cleaning of filter.
In order to improve the anti-cleaning efficiency of equipment, if the liquid outlet 503 on the piston has dried layer, on the piston 502
If liquid outlet 503 have dried layer, the distance between liquid outlet 503 described in adjacent two-layer be h, two neighboring filtration rear chamber 604
Between distance be a, then h=(n+1/2) * a, n is positive integer.The piston is provided with the through hole 506 in the same direction with filtering rod, to
The space between piston cylinder 4 between two pistons of connection.So guarantee that only one of which filter chamber, in anti-cleaning state, saves
The stroke of piston rod, save space.
For convenience the liquid outlet 503 is attached with circular hole on the piston cylinder 4, the piston be provided with circumference to
Groove 505, the liquid outlet 503 is arranged in the groove 505.When the circular hole is connected with the groove 505, it is equivalent to
Connect with the liquid outlet 503, shorten the time that inlet opening 401 is connected with circular hole on the piston cylinder 4, allow using more square
Just.
Because during anti-cleaning, the piston rod 501 will be moved relative to end cap 2, and the end cap 2 is needed
To coordinate with the sealing of the piston rod 501, therefore, sealing ring 203 is provided with the end cap 2 on the outside of circular hole, sealing ring 203 leads to
Cross the gland 204 of sealing ring 203 to be fixed on the end cap 2.In use for some time, the sealing effectiveness of sealing ring 203 declines,
Using said structure, very easily sealing ring 203 can be changed.The sealing ring 203 is using screw connection described
On end cap 2.
Mount and dismount for convenience, the piston cylinder 4 and the pressing plate 3 are bolted, i.e., the described bottom of piston cylinder 4
Portion is provided with screw hole, and the middle part of the pressing plate 3 is provided with round mouth.
The control to anti-cleaning process for convenience, is additionally provided with control valve on the piston rod 501.The benefit of do so
It is that one is to ensure that in filtration condition, prevents material from revealing from sewage draining exit, next to that in backwash state, by controlling valve
Blowdown flow is adjusted, the intensity of backwash is controlled.
The filter assemblies 6 include Inner guide disk 602, outer flow guiding disc 601, drainage screen 603 and supporting network, the supporting network
Including upper supporting network and lower supporting network, the drainage screen 603 is arranged between supporting network and lower supporting network, and the supporting network sets
Be placed between the Inner guide disk 602 and the outer flow guiding disc 601, the Inner guide disk 602, the outer flow guiding disc 601 with
The close circumferential envelope of support net coordinates, and two adjacent Inner guide disks 602 constitute filter chamber 605, two adjacent outer water conservancy diversion
The composition of disk 601 filters rear chamber 604.By the way that the drainage screen 603 is arranged between upper supporting network and lower supporting network, prevent because
Pressure-bearing causes the deformation of drainage screen 603.Additionally by the setting of Inner guide disk 602 and outer flow guiding disc 601, filtrate can be very square
Just inflow and outflow filter chamber 605 and filtration rear chamber 604, make filtrate circulation more smooth.
For convenience whole equipment is disassembled, and filter chamber's cylinder 1, piston cylinder 4 and end cap 2 pass sequentially through bolt company
Connect, between the filtration barrel body 1 and piston cylinder 4 and between the piston cylinder 4 and the end cap 2 sealing ring is equipped with.So
When there is part to need to change, very easily whole filter can be taken apart, the replacing of complete cheek, while sealing effectiveness
Well.
As shown in Figure 10, the filter also includes insulation jacket 7, and filter chamber's cylinder 1 passes through top location and installation
Mode is arranged in the insulation jacket 7 that (i.e. described insulation jacket is provided with top-fastening rod, and by top-fastening rod staving top will be filtered
Tightly).Insulation jacket 7 is provided with Heating medium and outlet, and the temperature of filtrate is kept by the heating agent for circulating.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by the scope of the claims.
