Description of the principle:
the invention designs three changeable flow passage structures of the multifunctional disc separator with changeable multiple flow passages, as shown in figure 1, figure 2 and figure 3.
As shown in fig. 1, fig. 5, fig. 8, fig. 10 and fig. 11, when the first flow channel is needed, a plug 29 is installed at the end of the channel-shaped flow channel 25 of the disc tray base 4, so that the feed material entering the fluid channel enclosed by the disc tray base 4 and the disc tray 5 cannot flow out from the end of the channel-shaped flow channel of the disc tray base 4. The bottom layer disc 601 adopts a disc with a bottom layer disc upper row hole 10 and no supporting ribs, the top layer disc 603 also adopts a disc with a top layer disc upper row hole 15 and no supporting ribs, which are the same as the bottom layer disc 601, the middle layer disc 602 adopts a disc with a middle layer disc upper row hole 12 and a middle layer disc lower row hole 13, and supporting ribs 14, the feeding material enters the upper row hole of the disc bracket 5 from a fluid channel enclosed by the disc bracket base 4 and the disc bracket 5 and then enters the disc upper row hole, and enters each layer of discs through the upper row hole of each layer of discs to separate phase components. Under the stirring of the discs rotating at high speed, the feed materials between the discs are separated under the action of centrifugal force, gravity, fluid resistance, friction force on the surfaces of the discs and the like, light liquid moves upwards between the discs, and heavy liquid and solid particles move downwards between the discs for separation.
As shown in fig. 2, 4, 9, 10 and 12, when the second flow channel is needed, a plug 29 is installed at the end of the channel-shaped flow channel 25 of the disc tray base 4, so that the feed material entering the fluid channel enclosed by the disc tray base 4 and the disc tray 5 cannot flow out from the end of the channel-shaped flow channel 25 of the disc tray base 4. The bottom layer disc 601 adopts a bottom layer disc lower row hole 11 and a rib-free disc, the top layer disc 603 also adopts a top layer disc lower row hole 16 and a rib-free disc which are the same as the bottom layer disc 601, the middle layer disc 602 adopts a disc with a middle layer disc upper row hole 12 and a middle layer disc lower row hole 13 and supporting ribs 14, the feeding material enters the lower row hole of the disc bracket 5 from a fluid channel enclosed by the disc bracket base 4 and the disc bracket 5 and then enters the disc lower row hole, and enters each layer of discs through the lower row hole of each layer of discs to separate phase components. Under the stirring of the discs rotating at high speed, the feed materials between the discs are separated under the action of centrifugal force, gravity, fluid resistance, friction force on the surfaces of the discs and the like, light liquid moves upwards between the discs, and heavy liquid and solid particles move downwards between the discs for separation.
As shown in fig. 3, 6, 7 and 10, when the third flow channel is needed, the bottom disc 601 is a non-porous and non-ribbed disc, the top disc 603 is a non-porous and non-ribbed disc similar to the bottom disc 601, the middle disc 602 is a disc with middle disc upper row holes 12 and middle disc lower row holes 13 and supporting ribs 14, and the feed cannot enter the holes of the disc tray 5 from the fluid channel enclosed by the disc tray base 4 and the disc tray 5 due to the blocking of the bottom and top non-porous discs. The end of the groove-shaped flow channel 25 of the disc tray base 4 is not provided with a block 29, so that the feed entering into the fluid channel enclosed by the disc tray base 4 and the disc tray 5 flows out from the end of the groove-shaped flow channel 25 uniformly distributed on the disc tray base 4 and enters into the drum space outside the disc. And then enters the space between the discs through the outer edge gap of the discs to separate the phase components. Under the stirring of the discs rotating at high speed, the feed materials between the discs are separated under the action of centrifugal force, gravity, fluid resistance, friction force on the surfaces of the discs and the like, light liquid moves upwards between the discs, and heavy liquid and solid particles move downwards between the discs for separation.
The supporting ribs 14 on the middle disc 602 serve to support and space the upper disc 603, and also reduce the flow of the feed material between the two discs, thereby improving the separation efficiency. The double-row hole structure can be used by replacing the bottom disc 601 and the top disc 603, so that the feeding has three flow channels. Top disc 603 and bottom disc 601 preferably do not have support ribs 14, and top disc 603 and bottom disc 601 may also be provided with support ribs 14 identical to middle disc 602.
The surfaces of the disc tray base 4, the disc tray 5 and the disc 6 can be plated with films to improve the hydrophobicity and oleophobicity of the surfaces of the disc tray base, the disc tray and the disc, further improve the anti-clogging capability and separation efficiency of the separator, and also improve the corrosion resistance of the disc tray base, the disc tray and the disc.
