Embodiment
As shown in Figure 1 and Figure 2, Fig. 1 is a kind of structural representation of vertical lower discharging centrifuge proposed by the present invention.Fig. 2 is
The structural representation of doctor assemblies in a kind of vertical lower discharging centrifuge proposed by the present invention.
Reference picture 1, a kind of vertical lower discharging centrifuge proposed by the present invention, including case 1, rotary drum 2, first driving dress
Put, supporting part 3, the drive device of doctor assemblies 4 and second, rotary drum 2 is rotatablely installed in case 1, and is driven by first driving means
Dynamic, rotary drum 2 includes being provided with solid-phase outlet 7 at the upper vertical tube part 5 and conical portion 6 being connected with each other, the bottom center of conical portion 6；
Second drive device includes motor 8, leading screw 9, guide rod 10, limited block 11 and sliding block 12, and leading screw 9 is by the top of case 1
Stretch into rotary drum 2, the driving forward or reverse of leading screw 9 of motor 8, guide rod 10 is parallel with leading screw 9, and is arranged in rotary drum 2, leading screw 9
Bottom is rotated with limited block 11 and is connected, and bottom and the limited block 11 of guide rod 10 are fixed, and sliding block 12 is set in leading screw 9 and guide rod 10
On, sliding block 12 coordinates with the screw thread of leading screw 9, and sliding block 12 is slidably connected with guide rod 10, and the driving leading screw 9 of motor 8 is rotated, and leading screw 9 passes through
Screw thread promotes sliding block 12 to move up or down, and guide rod 10, which plays a part of being oriented to and limits sliding block 12, to be rotated.
Supporting part 3 is located at the side of sliding block 12, and first end is fixed with sliding block 12；
Doctor assemblies 4 include knife rest 13 and scraper 14, and the second end and the knife rest 13 of supporting part 3 are fixed, in order to adapt to strike off
In the filter cake of different hardness, present embodiment, scraper 14 is made of hard alloy steel.
The lower section of limited block 11 is obliquely installed provided with secondary scraper 18, secondary scraper 18, gradient and the inner surface taper of conical portion 6
Identical, secondary scraper 18 extends to solid-phase outlet 7 by the upper bottom of vertical tube part 5, and secondary scraper 18 is along the contour line of the bearing of trend
, there is gap between secondary scraper 18 and upper vertical tube part 5, between secondary scraper 18 and conical portion 6 in logarithmic function curve.
Rotary drum 2, which rotates at a high speed, makes solid phase be attached to the internal face of rotary drum 2, and filter bores of the liquid phase on rotary drum 2 are thrown away, to case
1, and discharged by liquid-phase outlet thereon, during centrifugal dehydration, secondary scraper 18 is constantly a small amount of to the inner surface of conical portion 6
Solid phase is struck off, and is pushed into after solid-phase outlet 7, centrifugal dehydration end-of-job, and rotary drum 2 slowly runs, and starts motor 8,
Screw mandrel starts rotation, and scraper 14 is relatively rotated with the formation of rotary drum 2, and scraper 14 is moved up and down, and the filter cake of solid phase formation is carried out
Strike off, the solid phase struck off is fallen into conical portion 6, in the presence of secondary scraper 18, the solid phase unloaded is scraped into solid-phase outlet again
7, scraped clean under the collective effect of leading screw 9 and guide rod 10, improves the intensity for bearing moment of torsion.
In reference picture 2, present embodiment, the adjustable length of supporting part 3, during the length change of supporting part 3, doctor assemblies 4
There is gap all the time between rotary drum, scraper 14 is provided with pressure sensor 15,8 points of supporting part 3, pressure sensor 15 and motor
It is not connected with controller.Controller is obtained scraper 14 by Resistance Pressure information by pressure sensor 15 and is compared the value and preset value
Compared with, if its it is suffered be more than preset value by resistance, controller controlled motor 8 is stopped, and control supporting part 3 quickly shorten away from
From L1, the slow elongated distance L of controller control supporting part 31, in this process, each depth of cut by reducing, to protect
Scraper 14, is prevented because solid phase viscosity or hardness are too big, and infringement is produced to scraper 14.
In present embodiment, doctor assemblies 4 also include L-type pressing plate 17, and knife rest 13 is provided with groove 16, and scraper 14 is double end
Scraper, and middle part is provided with the first hole, the long slab of L-type pressing plate 17 is provided with the second hole, its short slab insertion groove 16, L-type pressing plate
The thickness that 17 short slab length is less than scraper 14 adds the depth sum of groove 16, and the short slab of the width of groove 16 and L-type pressing plate 17 is thick
Degree adaptation, L-type pressing plate is by press-fiting scraper 14 on knife rest 13 through the first hole, the second hole holding screw, and scraper 14 is fixed
Firm, dismounting is simple, after scraper 14 1, which scrapes head abrasion, to be scrapped, pulls down holding screw, replacing scrapes head to another, can extend scraper
Service life.
