A kind of Y type spiral-flow filter
Technical field
The present invention relates to a kind of filter, particularly a kind of Y type spiral-flow filter.
Background technology
Cyclone is as a kind of common separation classifying equipoment, and it is simple because have structure, and operation and installation are convenient, the advantage that production capacity is large.Application has expanded to chemical industry, environmental protection, food, light industry etc. in recent years, and its function is also from single separation function phase development in pluralism.
Its operation principle is centrifugal sedimentation.When two-phase (or three-phase) mixed liquor to be separated tangentially enters after in cyclone from cyclone periphery with certain pressure, produce the strong rotational shear turbulent motion of strong Three-Dimensional Elliptic.Owing to there is granularity difference (or density contrast) between coarse granule (or heavy phase) with fine grained (or light phase), its centrifugal force be subject to, centripetal buoyancy, fluid drag etc. vary in size, by centrifugal sedimentation effect, most crude particle (or heavy phase) is discharged through cyclone underflow opening, and most of fine grained (or light phase) is discharged by overflow pipe, thus reach the object being separated classification.
Along with the development of science and technology, it is also proposed higher requirement for the effect be separated and efficiency in each field, the separation equipment therefore researching and developing a kind of separative efficiency high is imperative.
Summary of the invention
It is high and be applicable to remove oarse-grained Y type spiral-flow filter in liquid that the technical problem to be solved in the present invention is to provide a kind of separative efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of Y type spiral-flow filter, is characterized in that: comprise the separating cyclone tube in stainless steel straight tube and upper end inclination insertion stainless steel straight tube,
One stainless steel straight tube, stainless steel straight tube is built-in with the baffle plate of a center drilling, and stainless steel straight tube is divided into admission chamber and spill cavity by this baffle plate; The stainless steel straight tube mouth of pipe of admission chamber side is inlet, and the stainless steel straight tube mouth of pipe of side, filtrate chamber is filtrate outlet;
One separating cyclone tube, separating cyclone tube is is coaxially connected and composed by top straight tube and lower taper cylinder, and straight tube upper end tilts insert the admission chamber of stainless steel straight tube and be connected and fixed with baffle plate, is the outlet of underflow liquid bottom conically shaped;
One filter core, filter core to be built in straight tube and axis and straight tube dead in line, and straight tube inner chamber is separated into outer shroud cyclonic separation chamber and center filter chamber by filter core, the built-in helical form flow deflector in outer shroud cyclonic separation chamber;
Described upper end, outer shroud cyclonic separation chamber is isolated by baffle plate and spill cavity, and top is communicated with admission chamber, and bottom and conically shaped inner chamber connect; Described upper end, center filter chamber is communicated with spill cavity by the centre bore of baffle plate, lower end and conically shaped inner space.
Preferably, described baffle plate and the axes normal of straight tube.
Preferably, described straight tube and conically shaped pass through Flange joint.
Preferably, the angle of described separating cyclone tube and stainless steel straight tube is 40 ~ 50 °.
Preferably, described filter core is stainless steel composite wire.
The invention has the advantages that: liquid enters stainless steel straight tube by inlet, change under the effect of baffle plate and flow to, enter the outer shroud cyclonic separation chamber of eddy flow current divider, under the effect of flow deflector, rotational flow field is at a high speed produced around filter core, part fluid directly enters center filter chamber through the filtration of filter core, spill cavity is flowed into from baffle center hole, major part fluid is through the effect of eddy flow, heavy decentralized photo is discharged from the outlet of underflow liquid, light decentralized photo enters center filter chamber from rising, the spill cavity of stainless steel straight tube is drained into again through baffle center hole, finally discharge from going out filtrate outlet.
Cyclonic separation is combined with the separating mechanism of filter, filter bypass is added in cyclone, separative efficiency improves greatly, and be applicable to remove oarse-grained impurity in liquid, this Y type spiral-flow filter is directly installed on pipeline by the flange of end, for separating of the solid particle in liquid phase, there is wide application space.

Detailed description of the invention
Embodiment
Refer to Fig. 1, present invention is disclosed a kind of Y type spiral-flow filter structure, comprise the separating cyclone tube in stainless steel straight tube 3 and upper end inclination insertion stainless steel straight tube 3, concrete structure is:
Stainless steel straight tube 3, stainless steel straight tube 3 is built-in with the baffle plate 5 of a center drilling, and stainless steel straight tube 3 is divided into admission chamber and spill cavity by this baffle plate 5; The stainless steel straight tube mouth of pipe of admission chamber side is inlet a, and the stainless steel straight tube mouth of pipe of side, filtrate chamber is filtrate outlet b; For easy to connect, stainless steel straight tube 3 mouth of pipe place inlet porting flange 4 of admission chamber side, stainless steel straight tube 3 mouth of pipe place of side, filtrate chamber arranges outlet(discharge) flange 1.
Separating cyclone tube, separating cyclone tube is is coaxially connected and composed by top straight tube 7 and lower taper cylinder 9, and straight tube 7 upper end tilts insert the admission chamber of stainless steel straight tube 3 and be connected and fixed with baffle plate 5, is underflow liquid outlet c bottom conically shaped 9.
As more particular embodiment of the present invention: the axes normal of baffle plate 5 and straight tube 7, the angle of separating cyclone tube and stainless steel straight tube is 40 ~ 50 °.
Filter core 2 is stainless steel composite wire, and filter core 2 to be built in straight tube 7 and axis and straight tube 7 dead in line, and straight tube 7 inner chamber is separated into outer shroud cyclonic separation chamber and center filter chamber by filter core 2, the built-in helical form flow deflector 6 in outer shroud cyclonic separation chamber.
For convenience of more renew cartridge 2 and flow deflector 6, above-mentioned straight tube 7 is connected and fixed by flange 8 with conically shaped 9.
Upper end, outer shroud cyclonic separation chamber is isolated by baffle plate 5 and spill cavity, and top is communicated with admission chamber, and bottom and conically shaped 9 inner chamber connect.Upper end, center filter chamber is communicated with spill cavity by the centre bore of baffle plate 5, lower end and conically shaped 9 inner space.
Operation principle:
Liquid enters stainless steel straight tube 7 by inlet a, change under the effect of baffle plate 5 and flow to, enter the outer shroud cyclonic separation chamber of eddy flow isocon, under the effect of flow deflector 6, rotational flow field is at a high speed produced around filter core 2, part fluid directly enters center filter chamber through the filtration of filter core 2, spill cavity is flowed into from baffle plate 5 centre bore, major part fluid is through the effect of eddy flow, heavy decentralized photo is discharged from underflow liquid outlet c, light decentralized photo enters center filter chamber from rising, the spill cavity of stainless steel straight tube 3 is drained into again through baffle plate 5 centre bore, finally discharge from going out filtrate outlet b.
The Y type spiral-flow filter scope of application in the present invention: in material, grain graininess is in following scope:
Grain graininess: 100% Dp >=3 μm
99.5% 0.5μm ≤Dp <8μm
10% Dp <20μm
Therefore being suitable for each needs removes oarse-grained occasion in liquid.
