Abstract
The invention relates to a vertical centrifugal settling solid-liquid separator and a separation method thereof. The separator comprises a frame and a power device. A centrifugal drum is suspended inside an outer shell, and is connected with the power device through a transmission system. The centrifugal drum is provided with a scraper and a feeding tube. The upper end of the centrifugal drum is connected with a bearing seat fixed on the outer shell through a bearing with a rotation shaft. According to the present invention, the manner of suspension of the centrifugal drum inside the outer shell is adopted, the separated liquid is discharged from holes on the upper portion of the centrifugal drum, the solid phase material is scraped by the scraper, and discharged from a material outlet on the lower portion of the centrifugal drum through gravity, and the centrifugal drum does not contact the treatment liquid during working. The separator and the separation method in the present invention are particularly suitable for solid-liquid separation situations of industrial and domestic sewage containing fine particles and charged micelles.
Description
Technical field
The invention belongs to the solid-liquid separation technique field, be specifically related to a kind of vertical centrifugal sedimentation solid-liquid separating machine and separation method thereof.
Background technology
A large amount of grinding water of using produce large amount of sewage after the operation when the grinding and polishing operation.This sewage contains a large amount of ultrafine solids particles, and not free settling for a long time suspends.Contain in the sanitary sewage relatively stable in a large number, with the charged micelle of water electrode tool affinity.When utilizing other separation means and equipment to carry out purification of water quality to the sewage in the above place, its cycle is long, cost is high and be difficult to up to standard.More feasible separate mode is to adopt the centrifugal sedimentation technology to accomplish at present.The centrifugal sedimentation solid-liquid separating machine, separation factor is high, is particularly suitable for the Separation of Solid and Liquid of low concentration (referring to solid concentration), ultra-fine grain system, generally uses at sewage treatment area at present.But it is horizontal that all at present its structures of centrifugal type solid-liquid separating machine are, and lean on helical structure scraping delivery solid-phase material.The characteristics of this structure cause following defective:
1, treatment fluid and helical structure collision, friction form turbulent flow, free settling not, wearing part.
2, the gapped need of turning cylinder seals, and material and processing technology are proposed high requirement.
3, because helical structure is arranged, asynchronous in the same way rotation need be joined the difference device.Cause geneogenous like this to material, processing technology requirement height, manufacturing cost height and poor reliability, poor stability.Power consumption, the horizontal type structure floor space is big, unfavorable applying.
Summary of the invention
The objective of the invention is to provide a kind of vertical centrifugal sedimentation solid-liquid separating machine and separation method thereof, treatment fluid does not have and leaks, and does not have the anti-sealing of divulging a secret; Separation factor is high, and is simple in structure, low cost of manufacture, and reliability is high, and easy to maintenance, floor space is little.Be particularly suitable for containing the industry of subparticle and charged micelle and the Separation of Solid and Liquid occasion of sanitary sewage.
The objective of the invention is to realize like this: a kind of vertical centrifugal sedimentation solid-liquid separating machine, comprise frame and power set, centrifugal basket is suspended in the outer casing, and centrifugal basket is connected with power set through transmission system, and centrifugal basket is equipped with scraper, feed pipe.
Centrifugal basket upper end is connected with bearing block on being fixed on outer casing through bearing by rotating shaft.
The outer casing lower end is provided with drainpipe.
Centrifugal basket top is provided with the hole, and the bottom is provided with discharging opening.
Said scraper is vertical scraper.
A kind of vertical centrifugal sedimentation solid-liquid separating method adopts suspension centrifugal basket mode in the outer casing, and the liquid after the separation is discharged from the hole on centrifugal basket top, and solid matter is scraped by gravity discharging opening discharge from the centrifugal basket bottom by scraper.
Built-in vertical scraper, the feed pipe of being equipped with of centrifugal basket, purging system, centrifugal basket does not contact with treatment fluid when separating solid phase, liquid phase substance.
When the solid matter of centrifugal basket inwall reaches certain thickness, provide the motor reduction of speed that signal makes power set by the control system, simultaneously scraper is scraped material towards barrel, scrapes material and accomplishes back scraper return, and the pump work of purging system is accomplished cleaning simultaneously.
A kind of vertical centrifugal sedimentation solid-liquid separating machine of the present invention and separation method thereof are scraped material, charging, purging system and are installed on the frame, are built in the centrifugal basket, do not contact with treatment fluid during mask work.Water is discharged by the discharge opeing inclined hole of centrifugal basket upper end, behind the outer casing water conservancy diversion, discharges through drainpipe.Scraper is vertical scraper, is complementary with vertical Separation of Solid and Liquid, and scraper is scraped junk and leaned on gravity to discharge from the discharging opening of centrifugal basket bottom.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is apparatus of the present invention structure charts.
The specific embodiment
A kind of vertical centrifugal sedimentation solid-liquid separating machine comprises frame 6 and power set 1, and centrifugal basket 3 is suspended in the outer casing 2, and centrifugal basket 3 is connected with power set 1 through transmission system, and centrifugal basket 3 is equipped with scraper 5, feed pipe 4.Centrifugal basket 3 upper ends are connected with bearing block on being fixed on outer casing 2 through bearing by rotating shaft.
Said scraper 5 is vertical scraper.
A kind of vertical centrifugal sedimentation solid-liquid separating method adopts suspension centrifugal basket 3 modes in the outer casing 2, and the liquid after the separation is discharged from the hole 8 on centrifugal basket 3 tops, and solid matter is scraped by gravity by scraper 5 and discharges from centrifugal basket 3 bottom discharging openings.
The power motor of centrifugal basket 3 also is installed on the outer casing 2, through belt transmission, drives centrifugal basket 3 work.Scrape material, charging, purging system and be installed on the frame 6, be built in the centrifugal basket 3.And centrifugal basket 3 tops have fluid inclined hole 8, but the bottom is provided with the discharging opening discharging.
Its course of work is: centrifugal basket 3 is rotation at a high speed under the drive of power motor, and sewage sprays into lower end in the centrifugal basket 3 through sewage feed pipe 4 after reaching the regulation rotating speed, in tube, rotates with tube.Sewage is fast hierarchical under the action of the centrifugal, and solid matter is near barrel, and liquid phase substance is away from barrel, and when reaching certain thickness, water is discharged by the discharge opeing inclined hole 8 of centrifugal basket 3 upper ends, through outer casing 2 water conservancy diversion after drainpipe 7 discharge.When the solid matter of centrifugal basket 3 inwalls reaches certain thickness, provide signal by the control system and make the motor reduction of speed, simultaneously scraper 5 is scraped material towards barrel, scrapes material and accomplishes back scraper 5 returns, and cleaning is accomplished in the scavenging pump work of purging system simultaneously.
