Abstract
One kind of feeder for settling tank is disclosed. The feeder has feeding pipe divided into two sections, including the back section with one bell connected and the front section stretched into the bell to form a Venturi tube structure, and can make the clear liquid layer in the settling tank generate self circulation to dilute the fed material slurry. Compared with available technology, the present invention has the advantages of improved red mud settling performance and other advantages.
Description
Technical field:
The invention belongs to red-mud settlement separator in the alumina producing, particularly a kind of subsider feeding device.
Background technology:
In aluminum oxide production process, the feeding manner of existing subsider is: slip is introduced into distribution box by feed pump, and then directly enter subsider by feed pipe, this subsider fed technology can not adapt to charging and contain the bigger condition of production of fluctuation admittedly, make subsider bear that risk ability reduces, disposal ability is low, rapid variation takes place in the fluctuation that subsider groove condition contains admittedly with charging, admittedly contain when increasing, red-mud settlement performance, compression performance variation, the subsider mud layer is increased, and muddy situation takes place to run in subsider.The frequent fluctuation of subsider groove condition is unfavorable for the control of technical indicator.
Summary of the invention:
The objective of the invention is to: a kind of effective feed arrangement is provided, improves the disposal ability and the ability to ward off risks of subsider, make subsider when charging contains fluctuation admittedly, can stable operation.
The present invention is achieved in that
This subsider feeding device comprises feed well (6), pump (5), feed pipe (3), subsider (1), feeding cylinder (2), feed well (6) is connected by the import of pipeline with pump (5), the outlet of pump (5) is connected with feed pipe (3) by pipeline, feed pipe (3) is on the top of subsider (1), and the back segment feed pipe (8) of feed pipe (3) inserts in the feeding cylinder (2).The interior feed pipe of subsider (1) (3) is two sections, and leading portion feed pipe (7) stretches into the anterior horn mouth (9) of back segment feed pipe (8), forms the Venturi tube structure.When utilizing fluid in Venturi tube, to move, its trunnion place produces vacuum state, make trunnion produce the characteristic of pressure differential on every side, the clear liquid at tomography place is sucked trunnion and enter once more in the feeding cylinder (2), thereby make subsider (1) upper clear supernate layer produce self-loopa, reaching dilution, feed slurry is liquid-solid contains, and improves the purpose of red-mud settlement performance.
Be divided into two sections feed pipe, leading portion feed pipe (7) caliber is little, and back segment feed pipe (8) caliber is big, and leading portion feed pipe (7) caliber is: 200-350mm, the ratio of itself and back segment feed pipe (8) caliber is: 1: 1.1-1.2, the ratio of leading portion duct length and back segment duct length is: 1: 0.8.
Slip in the feed well (6) is squeezed in the feed pipe (3) by pump (5), guarantees that slip has enough power in feed pipe (7), can bring the clear liquid that enters once more by horn mouth (9) into feeding cylinder (2).
Flocculant adds pipeline (4) and is connected with cell body outside, cell body inside and (2) three of the feeding cylinders of leading portion feed pipe (7) respectively, to guarantee the even interpolation of flocculant.
The present invention compares with existing subsider feeding device, has the following advantages:
(1) feed pipe forms Venturi tube structure, makes the supernatant layer clear liquid be brought into the subsider feed pipe once more under action of pressure, makes the subsider supernatant layer produce self-loopa, thereby dilutes fed slurry automatically, improves the red-mud settlement performance.
(2) adopt the direct and subsider feed pipe method of attachment of feed pump outlet, cancel original feed pump and be introduced into distribution box, and then the flow process that enters the subsider feed pipe, guarantee that slip has enough power in feed pipe, can bring the clear liquid that enters once more in feed pipe throat into feeding cylinder.
(3) flocculant feed pipe leading portion, 3 interpolations of feeding cylinder in feed pipe, the groove outside groove have respectively guaranteed the even interpolation of flocculant.
Description of drawings:
Accompanying drawing 1 is the structural representation of this device;
Accompanying drawing 2 is a feed pipe enlarged drawing partly among Fig. 1.
The specific embodiment:
Embodiments of the invention:
Slip in the feed well 6 is squeezed in the feed pipe 3 by pump 5, guarantees that slip has enough power in feed pipe 7, can bring the clear liquid that enters once more by horn mouth 9 into feeding cylinder 2.
Feed pipe 3 is two sections on the top of subsider 1, and leading portion feed pipe 7 stretches into the horn mouth 9 of back segment feed pipe 8 front portions, forms the Venturi tube structure.When utilizing fluid in Venturi tube, to move, its trunnion place produces vacuum state, make trunnion produce the characteristic of pressure differential on every side, the clear liquid at tomography place is sucked trunnion and enter once more in the feeding cylinder 2, thereby make subsider 1 upper clear supernate layer produce self-loopa, reaching dilution, feed slurry is liquid-solid contains, and improves the purpose of red-mud settlement performance.
Be divided into two sections feed pipe, leading portion feed pipe 7 calibers are little, and back segment feed pipe 8 calibers are big, and leading portion feed pipe 7 calibers are 200-350mm, the ratio of itself and back segment feed pipe 8 calibers is: 1: 1.1-1.2, the ratio of leading portion duct length and back segment duct length is: 1: 0.8.
Flocculant adds pipeline 4 and is connected with cell body outside, cell body inside and 2 three of the feeding cylinders of leading portion feed pipe 7 respectively, to guarantee the even interpolation of flocculant.
Claims (4)
