Abstract
A settlement type centrifugal separator with a double-stage rotary drum and a double-stage unloading spiral is mainly composed of a motor, a feeding device, a double-stage material accelerator, a double-stage rotary drum, a double-stage spiral conveying device and a differential, wherein materials have accelerating rotation via the double-stage rotary drum to separate solid phases from liquid phases; under the function of the differential, the double-stage spiral conveying device pushes separated solid phases at a slightly higher or lower speed than the rotary speed of the rotary drum; separated liquid phases overflow from an overflow hole at the big end of the double-stage rotary drum. After the materials are settled and separated by double-stage centrifugation, the present invention can lower the liquid containing rate of the separated solid phases, can enlarge the field of application, and has large practicability and social and economic benefits.
Description
(1) technical field
Patent of the present invention belongs to spiral discharge settling type centrifuge, and especially a kind of two-stage screw discharging centrifugal sedimentation isolating construction and material accelerator installation are applicable to the occasion that solidliquid mixture need carry out centrifugation and the solid phase mass dryness fraction after separating is had relatively high expectations.
(2) background technology
Before patent of the present invention was made, the spiral discharge settling type 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, differential mechanism 11 and automaton 12.Its operation principle is: motor 1 drives one-level rotary drum 6 and secondary rotary drum 9 rotation at a high speed by driving belt, under the effect of differential mechanism 11 and automaton 12, make one-level auger conveyor 7 to omit high (or lower slightly), with the equidirectional high speed rotation of rotary drum in the rotating speed 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 the liquid layer inner ring is overflowed from the one-level rotary drum 6 big spout holes of holding, and the solid phase of being close to drum inner wall is realized the separation of solid-liquid two-phase thus by outside one-level auger conveyor 7 kickoff mechanisms.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 dewatered, and makes the solid phase moisture content height after the separation, to difficult separation of material, is difficult to reach the requirement of production technology; 2, traditional first-stage centrifugal sedimentation separation centrifuge, the dehydration of solid phase is mainly carried out in the awl section of one-level rotary drum, because the diameter of awl section rotary drum diminishes gradually, promptly the suffered centrifugal force of solid-phase material also diminishes gradually, and this also is a main cause that causes solid phase effectively not dewater; 3,,, solid phase can't be input to and continue dehydration in second desk centrifuge because the solid phase after one-level is separated can not flow as if use that two traditional first-stage centrifugal sedimentation separation centrifuges are together in series; 4, traditional first-stage centrifugal sedimentation separation centrifuge does not have material centrifugation accelerates device, material to be separated is exported to rotatory drum wall from the auger conveyor cylindrical shell the distance of liquid layer inner surface is bigger, be that the suffered centrifugal force difference of material is big, easy disturbance centrifugal sedimentation liquid pool, separation process there is bigger influence, causes the solid phase solid content in the parting liquid higher.
(3) summary of the invention
The task of patent of the present invention is the shortcoming that overcomes prior art, provide a kind of rational in infrastructure, separating property good, separate back solid phase solid content height, can realize the solid-liquid separation mechanics of control automatically and protection according to magnitude of load.
A kind of solid-liquid separation mechanics with two-stage screw discharging centrifugal sedimentation isolating construction with the material accelerator, 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, differential mechanism 11 and automaton 12 are formed, motor 1 drives one-level rotary drum 6 and secondary rotary drum 9 rotation at a high speed by driving belt, under the effect of differential mechanism 11 and automaton 12, make one-level auger conveyor 7 and deuterostrophies conveyer 10 with slightly high (or lower slightly) rotating speed and the equidirectional high speed rotation of rotary drum, realize that secondary centrifugal sedimentation separates in rotary drum.
The device of patent of the present invention, compared with prior art, rational in infrastructure, separating property good, separate back solid phase solid content height, can realize control automatically and protection according to magnitude of load, have bigger implementary value and economic results in society.

(5) specific embodiment
Fig. 1, Fig. 2 are embodiment of patent of the present invention.As Fig. 1, shown in Figure 2, the embodiment of patent of the present invention is: a kind of solid-liquid separation mechanics with two-stage screw discharging centrifugal sedimentation isolating construction with the material accelerator, include 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, differential mechanism 11 and automaton 12, wherein one, two stage material accelerators 5,8 respectively by material speeding-up blade 13, material guide vane 15, accelerator ring flat-plate 14 is formed.It is characterized in that material to be separated after the material accelerator quickens, can obtain with liquid layer in the close peripheral velocity of ring, reduced disturbance to the centrifugal sedimentation liquid pool; After secondary centrifugal sedimentation separates, separate back solid phase solid content height, rational in infrastructure, good separating effect has bigger implementary value.
