Abstract
The utility model discloses a settling tank with a feeding device, which comprises flocculant feed pipes (1) and a feed pipe (2), wherein the feed pipe (2) is connected with an intermediate feed well (3), two flocculant feed pipes (1) are arranged above the intermediate feed well (3), the intermediate feed well (3) is positioned in the center of the upper part of the settling tank (4), and the feed pipe (2) consists of a straight steel pipe and a steel pipe with a socket. The settling tank can quickly settle and separate suspension.
Description
Technical field
The utility model relates to a kind of feed arrangement.
Background technology
In aluminum oxide production process, the suspension that has a lot of flow processs to exist solid particle and solution to form, the Separation of Solid and Liquid of these suspension is one of important steps of alumina producing.Separation of Solid and Liquid has important effect in alumina producing, to the output of alumina producing, quality and consumption have very big influence.Therefore, improving the processing quality and the efficient of the defecator that is used for Separation of Solid and Liquid, be of paramount importance index in alumina producing, and in the Separation of Solid and Liquid defecator, feeding manner directly affects the efficient of Separation of Solid and Liquid.
Usually when in defecator, adding suspension, there is not special device, directly reinforced with a feed pipe.When containing above certain numerical value owing to suspension is liquid-solid, the solid settling amount has the phenomenon of rapid decline, and the separating rate of suspension in defecator will be slow like this.Need contain charging admittedly and be diluted to suitable numerical value.
Summary of the invention
The technical problem that the utility model will solve: get into the slow problem of separating rate behind the defecator to present suspension through the common feed pipe, a kind of defecator of bringing materials device into that improves separative efficiency is provided.
The technical scheme of the utility model:
A kind of defecator feed arrangement comprises that flocculant adds pipe and feed pipe, and feed pipe is connected with middle feeding well, and middle feeding uphole is provided with two flocculants and adds pipe, and middle feeding well location is in the center upper portion of defecator.
Feed pipe is with bell-mouthed steel pipe to form by a straight steel pipe and one.
The beneficial effect of the utility model:
1, feed pipe by a straight steel pipe and one be with bell-mouthed steel pipe form in circulation from dilution system, during work, select to adopt suitable feed pressure; Fed slurry flows into certain flow rate from straight tube; At the horn mouth place, carry the clear liquid in the outer defecator supernatant layer of the middle feeding well of part, the dilution fed slurry; Get into middle feeding well with certain flow velocity tangent line; Form the sinking speed of certain centrifugal force and then raising material, improve consolidating of defecator deslagging and contain, increase substantially sinking speed and disposal ability.
2, have flocculant to add pipe, multiple spot and even continuous adding flocculant are with further raising flocculant effect of settling.
Description of drawings:
Fig. 1 is the utility model sketch map.
The specific embodiment:
Embodiment: feeding well 3 in the middle of the center upper portion of defecator 4 is provided with; The left side of middle feeding well 3 is connected with feed pipe 2; Feed pipe 2 is with bell-mouthed steel pipe to form by a straight steel pipe and one; In middle feeding well 3, be provided with 2 flocculants and add pipe 1, between middle feeding well 3 and defecator 4, be provided with a flocculant and add pipe 1.
Claims (3)
1. defecator of bringing materials device into; Comprise that flocculant adds pipe (1) and feed pipe (2); It is characterized in that: feed pipe (2) is connected with middle feeding well (3); Middle feeding well (3) top is provided with two flocculants and adds pipe (1), and middle feeding well (3) is positioned at the center upper portion of defecator (4).
2. the defecator of bringing materials device into according to claim 1 is characterized in that: feed pipe (2) is with bell-mouthed steel pipe to form by a straight steel pipe and one.
3. the defecator of bringing materials device into according to claim 1 is characterized in that: be provided with a flocculant between defecator (4) and the middle feeding well (3) and add pipe (1).
