Description
Technical field
The present invention relates to squeeze processing technology field, particularly relate to a kind of pressafiner.
Background technology
The standard design of pressafiner axial region dehydration is to adopt the axle screen frame rotating with the axis (slurry to be dewatered to axis direction at squeezing latter end, thereby realize the comparatively output mass dryness fraction of homogeneous), this axle screen frame is to be configured in a section of helical axis end there is no the cylindrical screen frame of spiral.Screen frame is arranged on axle, and rotates with the axis.In order to ensure that in expressing process, slurry does not rotate with the axis, conventionally on shell screen frame, guide groove is set.Under perfect condition, slurry reposefully to front slide, inwardly dewaters by axle screen frame on axle, outwards dewaters by shell screen frame.Due to the slip of slurry, axle screen frame there will be wearing and tearing.Another phenomenon that can observe is called as " slip-adhesion effect ".Specifically refer to, a bit of distance is rear adheres to again a bit of time to slurry on axle screen frame sliding.In the time that " slip-adhesion effect " occurs slurry, squeezer can produce very large vibrations, and may cause mechanical breakdown.
Summary of the invention
Based on this, be necessary for prior art defect, provide a kind of screen frame wearing and tearing and body reducing on helical axis to shake, reduce the pressafiner of failure rate of machinery.
Its technical scheme is as follows.
A kind of pressafiner, comprises shell and is sheathed on the helical axis in this shell, described helical axis comprises spiral section and static screen frame section, and this static screen frame section and shell are fixedly connected, and this spiral section can rotate around the axis of helical axis with respect to static screen frame section.
The spiral section of the helical axis of the technical program pressafiner and static screen frame section are split-type design, and the connection between open spiral section and static screen frame section is fixedly connected with static screen frame section simultaneously with shell.In the time that squeezer is worked, because static screen frame section is fixedly connected with shell, so in the time that spiral section rotates, the relative spiral section of static screen frame section is static, makes slurry no longer along with static screen frame section is rotated, and therefore slip-adhesion effect has lost direct inducement, the wearing and tearing of static screen frame section are obviously reduced, because the disappearance of slip-adhesion effect reduces body vibrations, reduced failure rate of machinery simultaneously.
In an embodiment, described spiral section and static screen frame section mutually close one end are that opposite end, the other end are away from end therein; Described spiral section opposite end and static screen frame section opposite end disconnect mutually.Spiral section opposite end and static screen frame section opposite end disconnect mutually, make at spiral section in the time that the axis of helical axis rotates, and static screen frame section can be static with respect to spiral section, avoids the generation of slip-adhesion effect.
Therein in an embodiment, described static screen frame section comprises truncated cone portion and the connecting portion being connected with this truncated cone portion, this truncated cone portion is dwindled away from end towards static screen frame section gradually by static screen frame section opposite end, in described truncated cone portion, be provided with sieve aperture, described truncated cone portion is fixedly connected by connecting portion and shell.Static screen frame section has truncated cone portion, and this has guaranteed compared with the static screen frame of column type, and the static screen frame section with truncated cone portion that has unloaded back pressure apparatus can reduce load (moment of torsion) quickly, thereby reduces the risk that slurry stops up.
In an embodiment, described static screen frame section opposite end and described shell are fixedly connected therein.Static screen frame section opposite end and shell are fixedly connected, and make at spiral section in the time that the axis of helical axis rotates, and static screen frame section can be static with respect to spiral section, avoids the generation of slip-adhesion effect.
Therein in an embodiment, the cylindrical shell that described static screen frame section is inner hollow, the end of static screen frame section opposite end is provided with sieve aperture.The end of static screen frame section opposite end is provided with sieve aperture, makes slurry inwardly form sieving liquid toward static screen frame section dehydration, and the static screen frame section of flowing through after sieving liquid does not have to discharge outside pressafiner after the part of sieve aperture.
In an embodiment, on the end face of described spiral section opposite end, be provided with bolster therein, this bolster is coaxial with described helical axis, and this bolster runs through static screen frame section and shell.Because spiral section and static screen frame section are mutually to disconnect, therefore be provided with the bolster coaxial with helical axis at the end face of spiral section opposite end, spiral section is connected with shell by bolster.
In an embodiment, described static screen frame section arranges installing plate away from end therein, and this static screen frame section is fixedly connected by installing plate and shell.On holding, installing plate is set in static screen frame section, installing plate on shell, is fixedly connected static screen frame section and shell by multiple bolt-lockings.
In an embodiment, pressafiner also comprises the sieving liquid discharge pipe communicating with static screen frame intersegmental part therein, and described sieving liquid discharge pipe runs through described installing plate and shell.Sieving liquid discharge pipe communicates with static screen frame intersegmental part, and sieving liquid discharge pipe runs through installing plate and shell, when slurry inwardly forms sieving liquid toward static screen frame section dehydration, after the static screen frame section of flowing through, is discharged outside pressafiner by sieving liquid discharge pipe after sieving liquid.
In an embodiment, described shell is provided with discharging opening therein, and described static screen frame section is corresponding with described discharging opening.Shell is provided with discharging opening, and slurry inwardly can be discharged from discharging opening after dehydration through static screen frame section.
