By adopting the distributing accelerator, the discharge direction can be changed, so that the impact force of materials discharged from the distributing holes on the settled solid phase at the inner wall of a drum is reduced as much as possible.
Description
Technical field
The utility model relates to centrifuge field, refers to especially a kind of horizontal spiral discharge sedimentation centrifuge cloth accelerator.
Background technology
Horizontal spiral discharge sedimentation centrifuge utilizes has different densities and immiscible light, heavy-fluid and solid phase in mixed liquor, obtain the principle of different sinking speed in centrifugal force field, reaches separated layering or makes the object of solid particles sediment in liquid.This type energy automatic continuous operation, is widely used in the industrial departments such as chemical industry, light industry, food, ore dressing, is also desirable equipment in environment-friendly engineering.After solid phase particles deposits in rotary drum, be under the promotion of screw rod, with the outlet of rotary drum small end solid phase, discharge.And screw rod is set to hollow structure, and the middle part of screw rod is to be provided with cloth accelerator, this cloth accelerator be provided with distribution cavity, the charging aperture of this distribution cavity is communicated with the charging mouth of pipe of centrifuge, cloth accelerator is provided with cloth hole, the structure in current cloth hole is strip or rectangle cloth hole, screw rod when rotated, cloth accelerator also rotates, material enters through the cloth hole of distribution cavity and discharges from charging aperture, and larger to the impulsive force of drum inner wall while causing material to be discharged from cloth hole due to the shape in cloth hole, so just may cause the solid phase that has originally been deposited in drum inner wall again to be broken up and by forming suspension.So just reduced centrifugal efficiency and the effect of sedimentation.
Utility model content
Technical problem to be solved in the utility model is: a kind of horizontal spiral discharge sedimentation centrifuge cloth accelerator is provided, this cloth accelerator can change discharging direction, thereby reduces as much as possible the material of discharging from the cloth hole impulsive force to the solid phase of drum inner wall sedimentation.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of horizontal spiral discharge sedimentation centrifuge cloth accelerator, this cloth accelerator is arranged at the stage casing of screw rod, this cloth accelerator comprises the connector that is arranged at screw rod stage casing, in this connector, be provided with distribution cavity, the front end of this distribution cavity is provided with charging aperture, the sidewall of described connector is provided with at least two cloth holes that are communicated with distribution cavity, and the hole in each rotation downstream, cloth hole is along extending towards rotation downstream arc from inside to outside.
As a kind of preferred scheme, the number in described cloth hole is two and arranges with respect to the axis Central Symmetry of screw rod.
As a kind of preferred scheme, the arc on the edge, hole in each rotation downstream, cloth hole extends to circular arc and extends.
As a kind of preferred scheme, equal arc-shaped transition between the edge, hole of the rotation upstream side in edge, the hole in the rotation downstream in any cloth hole and another cloth hole.
As a kind of preferred scheme, the charging aperture of described distribution cavity is arranged to taper, and charging aperture front end is osculum end.
As a kind of preferred scheme, the outer end of the front-end and back-end of described connector is along being provided with bevel for welding, and the front-end and back-end of described connector form whole screw rod with leading portion and the back segment welding of screw rod respectively.
Adopted after technique scheme, effect of the present utility model is: this cloth accelerator when rotated, shape and the track of material in distribution cavity from cloth hole along edge, hole outwards flies out, because extend towards rotation downstream arc from inside to outside on the edge, hole in each rotation downstream, cloth hole, therefore, the material flying out be not that direct projection is on the inwall of rotary drum, flying route with material in currently available technology compares, material of the present utility model to fly route rounder and more smooth, impulsive force to drum inner wall is less, like this, just can not upset the solid phase being deposited on drum inner wall, can improve separative efficiency and the separating effect of centrifuge.
Number due to described cloth hole is two and arranges with respect to the axis Central Symmetry of screw rod again, and like this, it is more reasonable that the material of cloth accelerator is discharged, and make the stress equalization of screw rod, reduces the vibrations that rotation produces.
Because extending to circular arc, extends the arc on the edge, hole in each rotation downstream, cloth hole again, therefore, direction when material is discharged from cloth hole is just pressed close to connector as much as possible, then principle drum inner wall as much as possible, thereby the impulsive force of the reduction material of maximum possible to drum inner wall, reduces the interference of the solid phase of sedimentation.
Again due to equal arc-shaped transition between the edge, hole in rotation downstream in any cloth hole and the edge, hole of the rotation upstream side in another cloth hole, therefore, material in distribution cavity just changes the direction of motion before discharging from cloth hole gradually in inside, thereby avoid material to fly direction abrupt change, avoid causing the turbulent flow of material.
Again because the charging aperture of described distribution cavity is arranged to taper, and charging aperture front end is osculum end, therefore, can avoid to a certain extent the backflow of material.
