Abstract
A sedimentation-type centrifuge with dual-stage rotary drum and dual-stage spiral discharge is composed of motor, feeder, dual-stage material accelerator, dual-stage rotary drum, dual-stage spiral conveyer and differential mechanism. The separated solid phase is discharged by spiral conveyer. The separated liquid phase is overflowed out from the overflow hole of rotary drum.
Description
The invention belongs to spiral discharge settling formula centrifuge, especially a kind of sedimentation-type centrifuge with twin-stage rotary drum and two-stage screw discharging is applicable to the low occasion of solid phase liquid holdup after solidliquid mixture need carry out centrifugation and require separation.
Before the present invention made, the spiral discharge settling formula centrifuge of prior art mainly was made up of motor 1, feed arrangement 2, base bearing 3, screw bearing 4, one-level rotary drum 6, one- level auger conveyor 7,11 of differential mechanisms.Its operation principle is: motor 1 drives one-level rotary drum 6 rotation at a high speed by driving belt, under the effect of differential mechanism 11, make one-level auger conveyor 7 with Lve Gao or a little less than the rotating speed of rotary drum, with the equidirectional high speed rotation of rotary drum, solidliquid mixture to be separated enters one-level rotary drum 6 by feed arrangement 2, under the effect of centrifugal force field, the liquid phase that is positioned at one-level rotary drum 6 bed of material inner rings is overflowed from the one-level rotary drum 6 big spout holes of holding, be close to the solid phase of one-level rotary drum 6 inwalls and released, realize the separation of solid-liquid two-phase thus by one-level auger conveyor 7.Its shortcoming is: 1, owing to be subjected to structural limitations, short through the time of staying of the solid phase after the initial gross separation in awl section rotary drum, solid phase can not effectively be taken off liquid, makes the solid phase liquid holdup height after the separation, to difficult separation of material, is difficult to reach the requirement of production technology; 2, the spiral discharge settling formula centrifuge of prior art can only carry out the first-stage centrifugal sedimentation separation, the taking off liquid and can only carry out of solid phase in the awl section of one-level rotary drum 6, because the diameter of awl section rotary drum diminishes gradually, be that the suffered centrifugal force of material also diminishes gradually, this also is to cause solid phase can not effectively take off a main cause of liquid; 3, the spiral discharge settling formula centrifuge of the prior art use of can not connecting because the solid phase after one-level is separated has been difficult to flow, can't be input to solid phase in second spiral discharge settling formula centrifuge and continues to take off liquid; 4, the spiral discharge settling formula centrifuge of prior art is not provided with material centrifugation accelerates device, make material littler than the centrifugal force that the liquid layer inner surface material that is positioned at drum inner wall produces from the centrifugal force that the auger conveyor outlet is produced, disturbance centrifugal sedimentation liquid pool causes the solid content of parting liquid to increase easily.
Task of the present invention is the shortcoming that overcomes prior art, provide a kind of rational in infrastructure, separating property good, the twin-stage rotary drum that the solid phase liquid holdup is low and solid content parting liquid is also low after separating and the sedimentation-type centrifuge of two-stage screw discharging.
A kind of sedimentation-type centrifuge with twin-stage rotary drum and two-stage screw discharging, mainly by motor 1, feed arrangement 2, base bearing 3, screw bearing 4, one stage material accelerator 5, one-level rotary drum 6, one-level auger conveyor 7, two stage material accelerators 8, secondary rotary drum 9, deuterostrophies conveyer 10 and differential mechanism 11 are formed, it is characterized in that one-level rotary drum 6 and secondary rotary drum 9 are installed on the base bearing 3, one-level auger conveyor 7 and deuterostrophies conveyer 10 are assemblied in respectively in one-level rotary drum 6 and the secondary rotary drum 9 by screw bearing 4, one stage material accelerator 5 is set in one-level auger conveyor 7, two stage material accelerators 8 are set in deuterostrophies conveyer 10, one stage material accelerator 5 and two stage material accelerators 8 are by material speeding-up blade 12, material guide vane 13 and accelerator ring flat-plate 14 are formed, differential mechanism 11 is connected with deuterostrophies conveyer 10 with one-level auger conveyor 7 by output shaft, make one-level auger conveyor 7 and deuterostrophies conveyer 10 with Lve Gao or a little less than one-level rotary drum 6, the rotating speed of secondary rotary drum 9 and the equidirectional rotation of this rotary drum, motor 1 is installed on the support of centrifuge, by belt and one-level rotary drum 6, secondary rotary drum 9 is connected.
Centrifuge of the present invention, compared with prior art, rational in infrastructure, separating property good, it is low and the parting liquid solid content is also low to separate back solid phase liquid holdup, has bigger practical value and economic results in society.
