Abstract
The utility model discloses a stable discharging device for settlement trough overflow. The stable discharging device comprises a settlement trough, wherein the upper part of the side wall of the settlement trough is connected with an overflow barrel by a pipeline; discharge holes, namely a discharge hole I and a discharge hole II, are connected to two sides on the bottom of the overflow barrel, respectively; the height difference between the end surface of the discharge hole I and the end surface of the discharge hole II is 5-40 centimeters; each of the discharge hole I and the discharge hole II is connected with a conveying pump. The stable discharging device disclosed by the utility model has beneficial effects that the two discharge holes in different positions are formed in the overflow barrel, so that the other discharge hole can be standby while one outlet pipeline has faults; the system is simple in structure, wide in range of application, and applied to all overflow systems in industrial production.
Description
Technical field
The utility model relates to alumina producing Bayer process field, relates in particular to a kind of stable drawing mechanism of subsider overflow.
Background technology
In the production system of alumina producing Bayer process, sedimenting system divides piece-rate system and back flush system, sedimenting system be take upper strata as clear liquid, lower floor realizes production for concentrating red mud, and supernatant liquor completes production by overflow system, the aluminium oxide and the sodium oxide molybdena that in overflow, contain high concentration, also has a small amount of mud scum, during long-play, on overflow cylinder and overflow pipe, easily produce and scab and mud scum deposition, sedimentation overflow system is caused to certain production accident, so must find a kind of practicality, effective production method, reduce and scab with mud scum sedimentation overflow system to the accident causing.
At present, subsider sidewall top connects overflow cylinder, overflow cylinder two bottom sides is respectively provided with a discharging opening, two discharging opening horizontal levels identical (as shown in Figure 1), when scabbing or deposition height during higher than discharging opening of overflow cylinder bottom deposition, if cleaning, there will be and emit groove phenomenon not in time, affect the operation of equipment.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of stable drawing mechanism of subsider overflow is provided, and it has simple in structure, applied range, improves the advantages such as utilization rate of equipment and installations.
To achieve these goals, the utility model adopts following technical scheme:
A kind of stable drawing mechanism of subsider overflow, comprise subsider, described subsider sidewall top is connected with overflow cylinder by the road, described overflow cylinder two bottom sides respectively connects a discharging opening, be respectively discharging opening I and discharging opening II, the difference in height of the end face of the end face of described discharging opening I and discharging opening II is 5-40 centimetre, and described discharging opening I is connected respectively a delivery pump with discharging opening II.
Described subsider, comprises cell body and baffle plate, and cell body bottom is provided with the gear with gradient.
The plane of described baffle plate and the angle between horizontal plane are 25 °-65 °.
The utility model is provided with two discharging openings, one of them does standby, the conveying delivery side of pump that discharging opening connects is set to single pump single tube, discharging opening I or discharging opening II are raised, when scabbing or deposition is deposited on overflow cylinder bottom, while stopping up lower position discharging opening, use high position outlet instead, avoid occurring emitting the production accidents such as groove.
The beneficial effects of the utility model: the stable drawing mechanism that a kind of subsider overflow is provided, at overflow cylinder, two outlets that position is different are set, guarantee that another outlet can reach standby when an outlet conduit breaks down, native system is simple in structure, applied range, is applicable to all overflow systems in industrial production.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is structural representation of the present utility model.
Wherein, 1. subsider, 2. overflow cylinder, 3. discharging opening I, 4. discharging opening II, 5. delivery pump.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 2, a kind of stable drawing mechanism of subsider overflow, comprise subsider 1, described subsider 1 sidewall top is connected with overflow cylinder 2 by the road, described overflow cylinder 2 two bottom sides respectively connect a discharging opening, be respectively discharging opening I3 and discharging opening II4, described discharging opening I3 sets high 20 centimetres than discharging opening II4 horizontal position, and described discharging opening I is connected respectively a delivery pump 5 with discharging opening II.
Described subsider 1, comprises cell body and baffle plate, and cell body bottom is provided with the baffle plate with gradient.
The plane of described baffle plate and the angle between horizontal plane are 25 °-65 °.
Described discharging opening I3 or discharging opening II4 are in running status, be that mono-of discharging opening I3 and discharging opening II4 are running status, one is stand-by state, when scabbing or deposition is deposited on overflow cylinder 2 bottoms, while stopping up discharging opening II4, use discharging opening I3 instead, in prior art, two discharging opening horizontal levels are identical, when scabbing or deposition is deposited on overflow cylinder 2 bottoms, two discharging openings all cannot discharging, and in the utility model, the conveying delivery side of pump that discharging opening connects is set to single pump single tube, discharging opening I or discharging opening II are raised, when scabbing or deposition is deposited on overflow cylinder bottom, while stopping up lower position discharging opening, use high position outlet instead, avoid occurring emitting the production accidents such as groove, do not affect the carrying out of production, can improve the utilization rate of equipment.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
