Abstract

The utility model relates to a vortex filter, which comprises an outer drum, an inner drum, a tangential inlet pipe, a filter element, an outlet pipe, a drain pipe and an inner circulating return pipe. The inner drum is arranged inside the outer drum, a gap is reserved between the top end of the inner drum and the outer drum, the tubular filter element is arranged inside the inner drum, a vortex chamber is formed between the inner drum and the filter element, the top end of the filter element is connected with the outlet pipe, the tangential inlet pipe is communicated with the bottom of the inner drum and extends to the outside of the outer drum, the inner circulating return pipe is arranged at the bottom of the inner drum, the vortex chamber is communicated with the outer drum via the inner circulating return pipe, and the drain pipe is arranged at the bottom end of the outer drum. The vortex filter has the advantages of reasonable structural design, high work efficiency and capability of effectively separating solid impurities in water.

Description

The swirl filter device

Technical field

The utility model relates to a kind of filter, particularly relates to a kind of swirl filter device.

Background technology

At present, Chang Yong solid-liquid separating equipment comprises filter, cyclone, centrifuge and settling tank etc.It is more direct to filter the kind equipment effect, but because there is filter core to need frequent clean or replacing; The automatic fitration machine can automatic backwash or cleaning, but complex structure; Centrifuge separative efficiency height, but operating cost height, maintenance cost is big, complex operation; Sedimentation basin capital cost height, floor space are big; Hydrocyclone structure is simple, and Technological adaptability is relatively poor, requires fluid conveying pressure constant, and separating effect is subjected to the influence of factors such as flow, blowdown big.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, the swirl filter device of high efficiency.

In order to address the above problem, the utility model by the following technical solutions:

A kind of swirl filter device, comprise urceolus, inner core, tangential entry pipe, filter core, outlet, blow-off pipe and inner circulating reflux pipe, urceolus inside is provided with inner core, leave the slit between inner core top and the urceolus, inner core inside is provided with the filter core of tubular, form the spin chamber between inner core and the filter core, the filter core top is connected with outlet, the tangential entry pipe is communicated with interior tube bottom and extends to outside the urceolus, interior tube bottom is provided with the inner circulating reflux pipe, the spin chamber is communicated with urceolus by the inner circulating reflux pipe, and the urceolus bottom is provided with blow-off pipe.

The spin chamber is positioned at urceolus by last position.

Compared with prior art, the beneficial effects of the utility model are;

The utility model is simple in structure, and is easy to use, easy to maintenance, can separate folded solid impurity in the water effectively, and fluid impedance losses is little, high efficiency.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

A kind of swirl filter device, as shown in Figure 1, comprise urceolus 1, inner core 2, tangential entry pipe 3, filter core 7, outlet 4, blow-off pipe 5 and inner circulating reflux pipe 6, urceolus 1 inside is provided with inner core 2, leave the slit between inner core 2 tops and the urceolus 1, inner core 2 inside are provided with the filter core 7 of tubular, form the spin chamber between inner core 2 and the filter core 7, the spin chamber is positioned at urceolus 1 by last position, the double solid particle settling chamber of doing of urceolus 1 lower space.Filter core 7 tops are connected with outlet 4, and tangential entry pipe 3 is communicated with inner core 2 bottoms and extends to urceolus 1 outside, and inner core 2 bottoms are provided with inner circulating reflux pipe 6, and the spin chamber is communicated with urceolus 1 by inner circulating reflux pipe 6, and urceolus 1 bottom is provided with blow-off pipe 5.

The course of work of this device is: contain the solid impurity current and at first tangentially enter the spin chamber from inlet tube 3, current rotate in the spin chamber and rise, the big solid impurity that centrifugal force will be clipped in the water is pressed to spin chamber's barrel, from the annular space of top, spin chamber and urceolus 1 loam cake, enter urceolus 1 on the whole under the drive of up-flow and finally fall into urceolus 1 bottom, regularly discharge urceolus 1 by blow-off pipe 5, water purification is discharged by outlet 4 after filtering through the tubular element 7 at center, spin chamber again, small solid impurity is tackled by tubular element 7, the current of spin chamber's inner high speed rotation produce negative pressure in spin chamber bottom centre, make the water after the clarification of urceolus 1 bottom reenter the spin chamber by inner circulating reflux pipe 6, and bring impurity into urceolus 1 from the top annular space once more as power, get back to the interior circulation of spiral-flow type from the inner circulating reflux pipe 6 of bottom, spin chamber again after the clarification, circulation can guarantee that the solid impurity in the urceolus 1 constantly accumulates in this, in the annular gap between spin chamber and tubular element 7, constantly wash away tubular element 7 by the liquid stream that rotates at a high speed, stop dirt in filter core 7 surface accumulation.Total is with the effect of tubular element 7 assurance Separation of Solid and Liquid, and with 7 obstructions of vortex prevention filter core, the formation of simultaneously interior circular flow can constantly accumulate impurity, increase blowdown concentration.

Claims
