Description

Have a rotor and the outlet of periodically discharging the product that separates is arranged and the cyclone of discharging the outlet of hydraulic fluid on rotor periphery

The present invention relates to a kind of cyclone, it comprises a rotor, when operation, openable first outlet is arranged in order to periodically to discharge the product that separates along peritrochanteric, also has second outlet, with first outlet certain axial distance is arranged, in order to discharge hydraulic fluid, this hydraulic fluid is supplied to rotor to handle first outlet; This cyclone also comprises a housing and a device around rotor, in housing, can constitute first Room around rotor, in order to accept and to lead away the products of separated that comes out from first, also has second Room, in order to accept and to lead away the hydraulic fluid that comes out from second around rotor.

In the cyclone of known type, it has a rotor that is supported by vertical axis, and two chambers around rotor separate with an annular space wall in housing.Spaced walls is made of housing self, indoorly resembles an open slot that makes progress round rotor above-mentioned first, outlet of product orientation of accepting.There is an independent outlet that the hydraulic fluid of accepting is discharged second Room.Two chambers are interconnected by the gap between rotor and the spaced walls, and are communicated with by outlet and hull outside separately.The chamber of hydraulic fluid also is communicated with by packing less opening of housing bottom and hull outside, and driving shaft stretches out from this opening.

In the running in this known cyclone, the centrifugal rotor ambient air is owing to the friction in itself and the rotor outside is rotated.In two chambers, produced effect thus as pump.The chamber of different designs and the outlet that is attached thereto in these cyclones, its result can produce following effect, be that air flows into second Room, part flows into first Room through the gap between rotor and the spaced walls again through the outlet of hydraulic fluid, and flows out from the outlet of products of separated.Air can also flow into second Room through the opening on the above-mentioned housing bottom, exists oil that the bearing that is provided with from the bottom comes and is carried secretly by air and enter two danger the chamber.

The air that the rotor that rotates produces in such a way flows, and causes leaving continuously or off and on the part hydraulic fluid of rotor, through being carried secretly the into receiving chamber of products of separated in above-mentioned gap.

On opening rotor during the outlet of products of separated, above-mentioned air flows and is subjected to the influence of the product that flows out from rotor.Usually, the pressure in first Room will increase certain degree, makes that producing the reverse gap of air stream between rotor and housing flows through.This reverse air flow causes the part of the products of separated of discharging to be carried secretly the receiving chamber that into accepts hydraulic fluid.

Above-mentioned air flows and the migration of incident hydraulic fluid and isolated product brings some shortcomings respectively.Therefore, usually not wishing that hydraulic fluid is lost to goes in the product of separation and/or the minimizing of latter's concentration.Based on other reason, do not allow that sometimes the product of separation is mixed with hydraulic fluid.In addition, the product of separation does not preferably flow into the receiving chamber that accepts working solution, because it pollutes hydraulic fluid on the one hand, the aspect has the product of the separation of making to be inhaled into the danger of going in the working rotor system and causing being deadlocked in addition.

The objective of the invention is to eliminate the above-mentioned shortcoming of the cyclone of the described known type of this specification introduction part, and between product that separates and hydraulic fluid, provide effective screening, make their unlikely mutual mixing.According to the present invention, above-mentioned purpose realizes by following way, utilize the spaced walls that centers on rotor and extend of two mutual axially spaced-apart certain distances that above-mentioned two chambers are separated to rotor, define a medial compartment between two chambers, it towards rotor uncovered and and the atmosphere of housing outside be connected.

Be described in detail the present invention with reference to the accompanying drawings.In the drawings, according to cyclone parts of the present invention, a part represents that with side view a part is represented with cutaway view.

Cyclone shown in the figure has a rotor 1, and it is supported and driven by a vertical axis 2, and is centered around in the fixing housing 3, and a plurality of first outlets 4 are arranged on the periphery of rotor, can periodically discharge the product that separates in rotor.Have the place of certain axial distance to have one second outlet at least with first outlet on rotor 1, in order to discharge hydraulic fluid, hydraulic fluid is supplied with rotor and is used for handling first outlet 4.Central inlet 6 also is housed on illustrated rotor, by the liquid mixture of centrifugal treating, two central outlet 7 and 8 is housed also, in order to export two kinds of liquid components in rotor, separating in order to input.

Housing around rotor supports with framework 9, and housing 9 is designed to have spaced walls 10 and 11, and they are the each interval certain distance in the axial direction, extends around rotor and to rotor.Therefore, space between rotor 1 and the housing 3 is divided into three chambers around rotor, first Room 12 is to be used for accepting and leading away from exporting 4 products of separated that come out, second Room 13 is to be used for accepting and leading away from second outlet, 5 hydraulic fluids that flow out, and medial compartment 14 is by 12,13 qualifications in two chambers.The shape of last spaced walls 10 resembles groove 15, around rotor, is used for the outlet 16 of products of separated guiding that receives in chamber 12.For the collection that guarantees products of separated with lead away, groove 15 be placed on than on the spaced walls 10 near on the lower level of the part of rotor.

An outlet 17 also is equipped with in second Room 13.Hydraulic fluid is gone from the derivation of second Room.Chamber 12 and 13 communicates by the atmosphere around

corresponding outlet

16,17 and the housing.

In illustrated embodiment, medial compartment 14 is communicated with by passage 18 in the framework 9 and the atmosphere around the cyclone.

She Ji cyclone in the manner described should be avoided flowing of air between the chamber 12 of accepting products of separated and the chamber 13 of accepting hydraulic fluid.Flow out from passage 18 from mobile can the replacing through medial compartment 14 of these two inevitable air in chamber, this is because its accordingly mobile latus rectum has the cause of minimum flow resistance.Like this, finally discharge through passage 18 respectively by mobile product of being carried secretly of air and hydraulic fluid.Therefore, between space 12 and space 13, can realize effective screening, no longer have any danger that makes products of separated and working solution mix and pollute mutually.

The atmospheric pressure of being mentioned in the above-mentioned and claim, promptly medial compartment 14 is conventional atmospheric pressures by 18 atmospheric pressures that are communicated with it of passage, but passage 18 also can be connected with another pressure.
