Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
nullAs Figure 1-4，Corrosion resistant type self-cleaning filter of the present utility model includes cylindric tank body 1,Be arranged in tank body at interval in the upper and lower and and inner tank wall between keep the up-hole plate 2 and the orifice plate 3 that seal,Described up-hole plate and orifice plate are respectively arranged with in three concentric circulars and the through hole 20 of uniform Boulez，It is preferably screwed hole，Chamber in tank body is from top to bottom divided into adjacent disconnected epicoele by described orifice plate and up-hole plate、Lumen and cavity of resorption，Wherein，Epicoele is connected via the central passage of cartridge filter with cavity of resorption，Described tank body is provided with the outlet pipe 4 corresponding respectively with described lumen and cavity of resorption and water inlet pipe 5，It is fixedly installed multiple with through hole cartridge filter 6 one to one between described up-hole plate and orifice plate vertically，Namely described cartridge filter is also in three concentric circular Boulezs，Its upper and lower two ends are fixing with corresponding through hole respectively to connect and keeps sealing，Preferably threaded，The blow-off pipe 7 that top blowdown motor 12 can be subject to drive and to rotate it is fixedly installed at described tank body center，On described blow-off pipe, side is connected to multiple L-type butt tube 8，Described L-type butt tube includes two groups axisymmetricly，Often three L-type butt tubes corresponding with concentric circular respectively of group，The opening of described butt tube is corresponding with the through hole of orifice plate，Described blow-off pipe lower end is tightly connected with sewage backwash pipe 10 is rotatable,Described sewage backwash pipe is provided with backwash valve 13,Unlatching or the stopping of pre-washing function can be realized sending out by controlling backwash control valve.
nullSelf-cleaning filter of the present utility model，Utilize up-hole plate and orifice plate that cavity is divided into multiple functional chamber，Former water is after water inlet pipe enters cavity of resorption，By entering in each cartridge filter after the through hole water distribution of orifice plate，After carrying out media filtration, impurity is retained，The cylinder sidewall of clear water inherent filtration cylinder flows out after then collecting and flows out from outlet pipe，Simultaneously，By blow-off pipe、The available pressure reduction of backwash mechanism that L-type butt tube and sewage backwash pipe are constituted starts、Start by set date or the multiple executive mode such as manually boot，The L-type butt tube corresponding with orifice plate can simultaneously by the central passage bottom of six cartridge filters and ft connection，Pressure within the cartridge filter now connected reduces，The top water inlet impact realizing backwash and central passage by middle intracavity relatively high pressure realizes multiple-effect backwash，Simultaneously，Other each cartridge filters are work still，Can guarantee that backwash normal water outlet constantly，Do not need to pull down filter element to clean，Can realize cleaning deslagging automatization.
Preferably, the L-type also including being correspondingly arranged up and down with described L-type butt tube cleans auxiliary tube, the described blow-off pipe described in auxiliary tube that cleans is connected, so, when performing backwash, the upper and lower two ends of central passage are cleaned by auxiliary tube and butt tube and external channel respectively, all rely on the clear water of lumen to carry out backwash, and developing result is good.
Preferably, described cartridge filter 6 includes being respectively formed at top and bottom and in order to the connecting portion 61 corresponding with the through hole of up-hole plate and orifice plate and forms the filter house 62 at middle part, and described filter house includes interval and arranges and respectively by the metallic fiber sintered inner core constituted be arranged on the support tube outside inner core.Described inner core is by diameter 1-5 μm, and as 3 μm metallic fiber sintered forms, described support tube is by diameter 70-80 μm, as 75 μm metallic fiber sintered forms.Specifically, metallic fiber sintered film is by very thin, it is the most carefully 1 micron, the metallic fiber easily intercepting less suspended solids is layered on the sintering of compacting together with three-dimensional labyrinthine pattern, the imperceptible surface that surface 1 micron metal fibrous layer is formed, it is easily formed cake layer, it is achieved the interception of a large amount of solid particles.The metallic fiber adopted in sintering process has significantly high L/D (length/diameter) ratio, and the numerous electric spot welding of fiber therefore can be made together thus being formed without the filter material of fibre shedding.This utility model makes full use of the surface filter cake of cylindrical metallic fiber sintering film and intercepts characteristic, and sound construction after sintering, aperture because of the change of pressure, will cause solid particle thoroughly to filter.Major part dirt be intercepted at filter cake surface, remove the gred effective, medium itself will not to water quality, environment, and resistance to chemical corrosion is good.
As a preferred version, it includes two spaced inner cores, and the inner core of inner side is formed by the metallic fiber sintered of diameter 4-5 μm, and the inner core in outside is formed by the metallic fiber sintered of diameter 1-3 μm.Adopt the metallic fiber of two-layer different-diameter, produce classified filtering effect, be greatly promoted its filtering accuracy.
Further, described connecting portion is fix the pushing out ring being connected with described inner core and urceolus, and a described pushing out ring is formed with threaded joints, and the connection of a pushing out ring and inner core and urceolus can adopt co-firing technology, and this is prior art, does not repeat again at this.
Preferably, for improving operation and the switching effect of L-type butt tube, it is respectively arranged with the ring groove corresponding with concentric circular at the upper surface of described up-hole plate with the lower surface of orifice plate.Utilize ring groove that the operation of butt tube is constituted to guide, improve the stability run.Preferably, it is provided with supersonic generator 9 in described L-type butt tube.As supersonic generator is arranged on the straight length top of butt tube, the work of supersonic generator is utilized to can further improve backwash effect.
Preferably, the bulge loop supporting the described orifice plate in location it is provided with in described tank body, described up-hole plate ring week is integrally formed with connection ring, described connection ring can be placed on tank body on adpting flange, connection ring is gripped by the uppercap body 11 fixing connection by means of described tank body, namely realizes the location of up-hole plate, also achieves the location of up-hole plate, orifice plate and cartridge filter simultaneously, integral disassembly, assembly is simple, it is easy to safeguard.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
