Description
Technical field
The utility model belongs to coal preparation plant's coal slime classifying equipoment field more particularly to a kind of hydraulic classiciation with screen construction
Cyclone.
Background technique
Conventional hydrocyclone is made of top cylinder and lower part cone, and cylinder top is provided with tangential feeding inlet, and center is set
Overflow pipe is set, there are underflow (desilting) mouth, ore pulps tangentially to enter cyclone under a certain pressure for cone lower part, acts in centrifugal force
Under, fine grained moves upwards, and is discharged through overflow pipe；Coarse granule moves downward, and is discharged through underflow opening.In practice, hydrocyclone
When for coal slurry classification, often there is overflow race slightly and thin phenomenon is pressed from both sides in underflow, influence grading effect.
Summary of the invention
The utility model aim is to provide a kind of hydraulic classification swirler, which solves lacking for existing cyclone
Point, improves classification efficiency.
To achieve the above object, the technical solution of the utility model is: a kind of hydraulic classification swirler, including cylinder barrel
Body, circular cone staving, round screen casing,
The cylinder staving upper end closed, lower ending opening, cylinder barrel body sidewall top are arranged along staving side wall tangential direction
There is feeding pipe, end face center is fixedly connected with the overflow pipe of vertical setting, and overflow pipe protrudes into inside cylinder barrel body, under the overflow pipe
Portion is fixedly connected with round screen casing,
The circular cone staving upper and lower opening, is connected to cylinder staving, and circular cone staving is consolidated by the first cone, the second cone
Fixed connection is formed, and the cone angle of first cone is greater than the cone angle of the second cone, first cone top and cylinder
Staving bottom is fixedly connected, and the bottom opening of the second cone is the underflow opening of circular cone staving.
The overflow bottom of the tube is not higher than feeding pipe pan feeding open height.
The circle screen casing is center screen casing, and by rivet interlacement in central overflow pipe lower part, length is adjustable, sieve
Stitch size view partition size setting.
First cone, cone angle are 30-90 degree.
The beneficial effects of the utility model are: thick and underflow is run in existing overflow during can effectively avoid cyclone classification
Thin phenomenon is pressed from both sides, so as to improve grading effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments:
A kind of hydraulic classification swirler, including cylinder staving 1, feeding pipe 2, overflow pipe 3, round screen casing 4, circular cone staving,
1 side wall upper part of cylinder staving is provided with feeding pipe 2 along staving side wall tangential direction, and end face center is fixedly connected vertical
The overflow pipe 3 of setting, overflow pipe 3 protrude into inside cylinder staving 1, and 3 lower part of overflow pipe is fixedly connected with round screen casing by rivet
4,3 bottom of overflow pipe is not higher than 2 pan feeding open height of feeding pipe, and 3 length of overflow pipe is adjustable, and screen slot size is set depending on partition size
It sets；
Circular cone staving upper and lower opening, is connected to cylinder staving 1, and circular cone staving is by the first cone 51, the second cone 52
Flanged joint is formed, and the cone angle of the first cone 51 is greater than the cone angle of the second cone 52,51 top of the first cone and cylinder
1 bottom of staving is fixedly connected, and the bottom opening of the second cone 52 is the underflow opening 53 of circular cone staving.First cone, cone angle
For 30-90 degree；Second cone, cone angle and underflow tap diameter are adjustable.
Working principle: certain density ore pulp pump is squeezed into feed inlet, material forms a revolution inside cyclone
It flows, the ore pulp rotational speed at cyclone center is maximum, and the centrifugal force of generation is also maximum.Ore pulp radiates out the result of movement
It is one depression belt of formation around central axis, at this point, sucking air by underflow opening, and forms a low pressure in central axis
Air column.Ore pulp has tangential rotary motion in cyclone, also there is inside radial motion, and by paracentral ore pulp along axis
To moving upwards, peripheral ore pulp is mainly moved downward.Fine grained centrifugal sedimentation speed is small, is forced into center by centripetal liquid stream
Overflow pipe becomes overflow product, and since screen casing aperture is 0.25mm, then the coarse grain greater than 0.25mm not can enter central overflow
Pipe, so that effectively preventing overflow runs thick problem；The centrifugal force that coarse granule is subject to is larger, moves downward with flow of slurry, the bottom of by
Head piece discharge becomes underflow product.It is influenced by liquid stream entrainment, part particulate, these particulates would generally be contained in downward flow of slurry
Cone is moved to flow of slurry, and thrust of the different cone angle structure of the first and second cone to material one obliquely makes mine
Slurry stream pours into center, and particulate may pass through screen casing and enter into and up movement, becomes overflow product, and last coarse grain is with pulp flow to the
Two cone bottoms, are discharged by underflow opening.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.
