Abstract
The invention discloses a spiral discharge disk plate centrifuge used for separating two-phase or three-phase heterogeneous mixtures, comprising a drum system, a spiral-disk plate system, a feed coupling device, a discharged liquid coupling device, a discharged residue coupling device, a case and a base. The drum system is borne by a left bearing and a right bearing. Disk plates are stacked on a disk plate shaft layer by layer and are fixed by conoid disk plate glands. A plurality of waist-shaped holes are arranged in the middle of the disk plate glands. The spiral-disk plate system is borne between a left hollow shaft combined by the spirals and the disk plates and a right hollow shaft combined by the spirals and the disk plates. Radial feed through-holes are arranged at the right ends of the left hollow shaft combined by the spirals and the disk plates and a left hollow shaft of the drum. The spiral-disk plate system and the drum system rotate in the same direction and the spiral-disk plate system has 0.2-3% velocity difference relative to the drum system. The centrifuge discharges the residues not around the disk plates but at the small head ends of the conoid disk plates, and the sediment has low liquid content. The liquid is discharged in the center of the drum along the axis but not in the spiral cavity, thus conducing to interference-free discharge after solid-liquid stratifying.
Description
Technical field
The present invention relates to the sedimentation centrifuge in the separation equipment, relate in particular to helical-conveyer centrifugal.
Background technology
Sedimentation centrifuge in the market mainly contains three major types: tube centrifuge, disk plate centrifuge and helical-conveyer centrifugal.Wherein, tube centrifuge is intermittently operated, and critical piece is a rotary drum that draw ratio is bigger, and rotating speed is higher, and its defective is: can not continuous discharging slag when being used for Separation of Solid and Liquid, can only be used for the lower Separation of Solid and Liquid of solid content, and disposal ability is less.Disk plate centrifuge utilizes shallow pool principle, and main working parts is one group of video disc, and the deslagging mode is the nozzle deslagging and encircles two kinds of valve deslagginves that its defective is: exist and stop up or the slagging channel wear problem.The principal character of helical-conveyer centrifugal is to also have a spiral in rotary drum, though can realize continuous discharging slag, because of there being certain speed discrepancy between rotary drum and the spiral, so separative efficiency is very low.
Summary of the invention
The objective of the invention is under the prerequisite that guarantees high separating efficiency, to realize continuous discharging slag, thereby realize the Separation of Solid and Liquid of continuous high-efficient, and avoid the blockage problem or the slag-drip opening wear problem of traditional disk plate centrifuge deslagging for overcoming the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is to comprise rotor system, spiral system, video disc system, charging connection, fluid connection, the connection of slagging tap, casing and base; Rotor system is bearing in left side supporting and the right supporting, spiral-video disc system is made up of described spiral system and video disc system, spiral-video disc system comprises that cylindrical spiral and tapered auger are fixed on around the video disc and the three rotates in the same way, video disc overlays layer by layer on the video disc axle and with the video disc gland of taper and fixes, and several mounting holes are set in the middle of the video disc gland; Between the right hollow shaft that the left hollow shaft that spiral-video disc system is bearing in spiral video disc combination and spiral video disc make up, the left hollow shaft of spiral video disc combination is arranged in the rotary drum left side hollow shaft of rotor system and stretches out outside it, the right hollow shaft of spiral video disc combination is arranged in the right hollow shaft of rotary drum of rotor system and stretches out outside it, is provided with the charging radial direction through hole at the left hollow shaft of spiral video disc combination and the right-hand member of rotary drum left side hollow shaft; The right hollow shaft of spiral video disc combination is provided with bellmouth and communicates with mounting hole on the video disc gland; Spiral-video disc system and rotary drum in the same way system rotation and spiral-video disc system to be provided with 0.2-3% speed with respect to rotor system poor.
The invention has the beneficial effects as follows:
1, with the contrast of traditional disk plate centrifuge, deslagging of the present invention is not around video disc, and at the little head end of taper video disc, sediment is through carrying and compression, and liquid content is little.
2, with the contrast of traditional helical-conveyer centrifugal, along axis, not in helical cavity, promptly liquid, slag help the noiseless discharge after the solid-liquid layering not in the same space at the rotary drum center in discharge opeing of the present invention.Compare with traditional helical-conveyer centrifugal of same size, the settling area order of magnitude increases, and the time of staying prolongs, and the settling height order of magnitude reduces, and littler particle can be separated, and separative efficiency significantly improves.
3, the present invention can be used for the separation of solid-liquid, liquid-liquid, solid-liquid-liquid two-phase or three-phase non-homogeneous mixture.
