Principle explanation:
There are three types of the convertible flow passage structure of the multi-functional disk centrifuge of convertible multiple flow passages designed by the present invention has altogether, such as
Shown in Fig. 1, Fig. 2 and Fig. 3.
As shown in Fig. 1, Fig. 5, Fig. 8, Figure 10 and Figure 11, when needing to realize the first runner, in disk bracket base 4
25 end of channel form runner installs stifled 29, makes to enter in the fluid channel surrounded by disk bracket base 4 and disk bracket 5
Charging cannot be flowed out from 4 channel form flow field end of disk bracket base.Bottom disk 601, which uses, round on bottom disk
10, without support rod disk, top layer disk 603, which also uses, and bottom disk 601 is identical has round 15 on top layer disk, without muscle
Disk, middle layer disk 602 is using having on the disk of middle layer 13 double-row hole of round under round 12 and middle layer disk, have support rod
14 disks, charging enter the upper round of disk bracket 5 from the fluid channel surrounded by disk bracket base 4 and disk bracket 5,
Round on disk is entered back into, the separation for carrying out each phase constituent is entered between each layer disk by the upper round of each layer disk.In height
Under the disk agitation of speed rotation, the charging between disk is in power such as centrifugal force, gravity, fluid resistance, disc surface frictional force
Effect is lower to carry out disengaging movement, and light liquid moves upwards between disk, heavy-fluid and solid phase particles moved downward between disk into
Row separation.
As shown in Fig. 2, Fig. 4, Fig. 9, Figure 10 and Figure 12, when needing to realize second of runner, in 4 ditch of disk bracket base
25 end of groove shaped flow conduits installs stifled 29, makes to enter in the fluid channel surrounded by disk bracket base 4 and disk bracket 5
Charging cannot be flowed out from 4 channel form runner of disk bracket base, 25 end.Bottom disk 601, which uses, round under bottom disk
11, without rib disk, top layer disk 603, which also uses, and bottom disk 601 is identical has round 16 under top layer disk, without rib dish
Piece, middle layer disk 602 is using having on the disk of middle layer 13 double-row hole of round under round 12 and middle layer disk, have 14 dish of support rod
Piece, charging enter the lower round of disk bracket 5 from the fluid channel surrounded by disk bracket base 4 and disk bracket 5, then into
Enter round under disk, the separation for carrying out each phase constituent is entered between each layer disk by the lower round of each layer disk.Turn in high speed
Under dynamic disk agitation, the effect of charging between disk in power such as centrifugal force, gravity, fluid resistance, disc surface frictional force
Lower carry out disengaging movement, light liquid move upwards between disk, and heavy-fluid and solid phase particles move downward point between disk
From.
As shown in Fig. 3, Fig. 6, Fig. 7 and Figure 10, when needing to realize the third runner, bottom disk 601 uses non-porous, nothing
Rib disk, top layer disk 603 also using and bottom disk 601 it is identical it is non-porous, without rib disk, middle layer disk 602 is adopted
With having on the disk of middle layer 13 double-row hole of round under round 12 and middle layer disk, having 14 disk of support rod, since Di Heding is non-porous
The blocking of disk, charging cannot enter disk bracket 5 from the fluid channel surrounded by disk bracket base 4 and disk bracket 5
Hole.Stifled 29 are not installed in 4 channel form runner of disk bracket base, 25 end, make to enter by disk bracket base 4 and disk support
The charging in fluid channel that frame 5 is surrounded is evenly distributed with 25 end of channel form runner from disk bracket base 4 and flows out, into outside disk
The rotary drum space of side.Enter between each layer disk the separation for carrying out each phase constituent by the outer ledge gap of each layer disk again.
Under the disk agitation of high-speed rotation, the charging between disk is in centrifugal force, gravity, fluid resistance, disc surface frictional force etc.
Disengaging movement is carried out under the action of power, light liquid moves upwards between disk, and heavy-fluid and solid phase particles are transported downwards between disk
It is dynamic to be separated.
Play support upper layer disk 603 and spacing in intermediate 602 support rod 14 of disk, charging can also be reduced two
Process between disk improves separative efficiency.The structure of this double-row hole can pass through replacement bottom disk 601 and top layer disk
603 are used cooperatively, and making charging tool, there are three types of runners.Top layer disk 603 and bottom disk 601 do not have support rod 14 preferably,
Top layer disk 603 can similarly be equipped with support rod 14 identical with middle layer disk 602 with bottom disk 601.
Disk bracket base 4, disk bracket 5 and 6 surface of disk can also carry out surface coating, to improve disk bracket bottom
Seat, disk bracket and disc surface hydrophobicity and oleophobic property, further increase the silting blocking ability and separative efficiency of seperator,
It can be further improved the corrosion resistance for improving disk bracket base, disk bracket and disk.
