Description

A kind of cyclone with water seal underflow mouth structure

Technical field

A kind of cyclone is the utility model is related to, especially a kind of cyclone with water seal underflow mouth structure.

Background technology

Cyclone is a kind of common separation classifying equipoment, using centrifugal sedimentation principle, when mixed liquor to be separated is with one Constant-pressure from cyclone periphery tangentially enter cyclone in after, it is poor due to granularity between coarse granule and fine grained be present, its by Centrifugal force, centripetal buoyancy and fluid drag etc. are of different sizes, are acted on by centrifugal sedimentation, and most crude particle is through cyclone underflow opening Discharge, and most of fine grained is discharged by overflow pipe, so as to reach separation classification purpose.But most of cyclone is working When, because underflow opening is in communication with the outside, there can be air column in cyclone, the stream in cyclone has been upset in the presence of air column , energy loss is caused, reduces the classification efficiency and effectiveness of classification of cyclone.

Utility model content

It is in communication with the outside to solve existing cyclone underflow opening, influences cyclone work so as to form air column in spin chamber Make efficiency and the technical problem of effectiveness of classification, the utility model provides a kind of cyclone with water seal underflow mouth structure, its Concrete technical scheme is as follows：

A kind of cyclone with water seal underflow mouth structure, including spin chamber and pressurize room, spin chamber include column body segment and Cone segments, pressurize room are the columnar structured bottom for being arranged on spin chamber；Charging aperture and overflow are provided with spin chamber's column body segment Pipe, the cone segments lower end of spin chamber are provided with underflow opening, and underflow opening extends pressurize room bottom；Pressurize room bottom is provided with particulate matter Outlet and ball valve.

Preferably, the column body segment of spin chamber and cone segments are integral type structure, the cavity of cone segments and the cavity of column body segment It is collectively forming cyclonic separation chamber；The overflow pipe is arranged on column body segment, and spin chamber, the lower end of overflow pipe are stretched out in the upper end of overflow pipe Extend following in the middle part of spin chamber's column body segment；The charging aperture is opened in column body segment top.

Preferably, pressurize room is connected with spin chamber's cylinder pars infrasegmentalis, and pressurize room is highly more than spin chamber's cone segments height, protects The cone segments shell of pressure chamber and spin chamber forms closed structure.

Preferably, liquid level in the ball valve control pressurize room of pressurize room, liquid level is consistently higher than eddy flow in pressurize room The underflow opening of room, form water seal underflow opening.

Preferably, column body segment axial line, cone segments axial line, underflow opening axial line, overflow tube axis line and pressurize room axle Heart line coincides, and the charging aperture axial line and overflow tube axis line of the spin chamber are perpendicular.

The beneficial effects of the utility model mainly have：Pass through column body segment axial line, cone segments axial line, underflow opening axle center The design that line, overflow tube axis line and pressurize room axial line coincide reduces the energy loss of cyclone, improves cyclone Operating efficiency, extend the service life of cyclone.It is following in the middle part of column body segment by the way that overflow pipe is arranged on, so as to more effective Small particle is exported out of spin chamber.By making the cone segments shell of pressurize room and spin chamber form closed structure, and will Underflow opening is extended under the liquid level in pressurize room, and the underflow opening of spin chamber is sealed by liquid, is not contacted directly with outside air, underflow Mouth constantly discharge liquid compression pressurize room air, avoids the generation of spin chamber centre air column, facilitates ball valve to open Granule materials quickly flow out out of pressurize room afterwards, and reduce the energy loss in the cyclone course of work, ensure that flow field point Cloth is uniform, improves separative efficiency and effectiveness of classification.
