Abstract

The utility model relates to a centrifugal filter for the industries of oil extraction, chemical engineering, water supply, etc., which comprises a housing 1, a press cover 2, and a filter core 18 arranged in an inner cavity of the housing. The utility model is characterized in that a blade shaft capable automatically rotating and blades 10 inserted on the blade shaft are arranged between the press cover 2 and the filter core 18, and the lower end of the blade shaft 19 is provided with a centrifugal leaf 17. When a fluid with certain pressure passes through the centrifugal filter, the blades 10 are driven to rotate, and drive the blade shaft 19 and the centrifugal leaf 17 to rotate to promote the accelerated separation of heterogeneous-phase mixtures in the fluid, and therefore, the utility model has the characteristics of high filtering speed, high efficiency, thorough separation of the heterogeneous phase mixtures, etc.

Description

Centrifugal type filter

The utility model relates to a kind of filter that is used for bodies for purifying fluids purity in industries such as oil exploitation or chemical industry, feedwater, oil refining, air feed.

Traditional filter is fixed filter, is made up of housing, gland and the filter core that is arranged on the housing inner chamber.Because this filter just reaches the purpose of bodies for purifying fluids purity by fluid self pressure by filter core, so exist shortcomings such as the rate of filtration is slow, filter efficiency is low, the non-homogeneous mixture separation is not thorough.

The purpose of this utility model is to provide a kind of can impel non-homogeneous mixture generation centrifugal force in the fluid, thus the centrifugal type filter that quickens separation.

The utility model is achieved in that a kind of centrifugal type filter, comprises housing, gland and is arranged on the filter core of housing inner chamber, is characterized in being provided with rotatable sharf between gland and filter core and is inserted into blade on the sharf.When the fluid with certain pressure when fluid intake flows into, promote the blade rotation, thereby drive the sharf rotation, quicken the sedimentation of particle in fluid, reach the purpose of bodies for purifying fluids.

The utility model can also be installed a centrifugal leaf again in above-mentioned sharf lower end.

Sharf of the present utility model rotation automatically is by realizing like this: an activity adjustment screw is set between sharf and gland, between activity adjustment screw and sharf ball is housed, be set with dividing plate and bearing at the sharf middle part, dividing plate is shelved on the housing.

Compare with traditional fixed filter, the utility model is owing to set up rotatable sharf and blade in filter interior, one centrifugal leaf is installed in the sharf lower end again, when the fluid with certain pressure passes through filter, the rotation of promotion blade, blade then drives sharf and the rotation of centrifugal leaf, promote non-homogeneous mixture generation centrifugal force in the fluid, under centrifugal action, non-homogeneous mixture in the fluid, particulate etc. quicken to separate under inertia, quicken the sedimentation of particle in fluid.Therefore the rate of filtration fast 3-5 of normal filtration speed (be equivalent to doubly) efficient height, non-homogeneous mixture separates thoroughly.The pressure of fluid is high more, flow velocity is fast more, and the centrifugal force that is produced is big more, and the rate of filtration is fast more, thorough more, and filter effect is good more.

Fig. 2 is a blade axle construction schematic diagram of the present utility model.

Fig. 3 is that the C of Fig. 2 is to view.

Fig. 4 is a blade thin-slab structure schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

As shown in Figure 1, this centrifugal type filter primary structure is by housing 1, gland 2 and be arranged on the filter core 18 of housing 1 inner chamber and be arranged on gland 2 and the rotatable sharf 19 of 18 of filter cores, blade 10, is opened in the compositions such as sample tap 13 in housing 1 outside.Wherein gland 2 tops are equipped with flat shim 4, acorn nut 6,1 of gland 2 and housing are equipped with sealing ring 3: at

sharf

19 and 2 on gland an activity adjustment screw 7 is set, 19 of activity adjustment screw 7 and sharfs are equipped with ball 9, be set with dividing plate 12 and thrust bearing 11 at sharf 19 middle parts, dividing plate 12 is shelved on the housing 1.Centrifugal leaf 17 is equipped with in sharf 19 bottoms, and fixes with connecting bolt 15, pad 16.Sharf 19 can divide blade axle 8 and inferior lobe bobbin 14 two parts, and blade 10 is inserted between upper and lower sharf.Shown in Fig. 2-3, all have " ten " word groove 20 in the middle of the upper and lower sharf 8,14, blade 10 just is inserted in this groove, and this blade 10 is made up of thin plate 21 plug-in mountings that two centres have groove 22, as shown in Figure 4.

Operation principle: when fluid from " A " to flowing into housing, sedimentator rotates at a high speed, the medium that enters filter core rotates the generation eddy current at a high speed, promote non-homogeneous mixture, particulate in the fluid to quicken the precipitation 3-5 of normal filtration speed (be equivalent to doubly), liquid juice (gas) to outflow, reaches the purpose of filtration from " B ".
