Abstract
The utility model discloses a new-type feeding system for the deep cone high efficient settling tank, which comprises the feed pipeline, mixer and flocculating agent feeder. It is characterized in that: two or more feed pipes and coordinating mixer and flocculating agent feeder are installed. This utility model can not only dilute the solid content of feed, fully mix the flocculating agent and red mud to speed up the settlement of red mud, but also ensure that under the working condition of great fluctuation in feed amount, the settling tank can operate stably and constantly. Therefore, this utility model can enable a series of red mud settlement and cleaning deep cone high efficient settling tank to meet the production requirements for two or three dissolution production lines. In addition, this utility model simplifies the process of equipment, economizes the investment and operational cost of project.
Description
Affiliated technical field
The utility model relates to the deep-cone settling groove of red-mud settlement separating, washing in a kind of alumina producing, particularly relates to the feed system of deep-cone settling groove.
Background technology
In recent years in the red-mud settlement separating, washing process in alumina producing, be extensive use of the deep-cone settling groove, the core technology of this subsider is a feeding pipe that comprises Venturi tube 2, it can contain the subsider charging admittedly and is diluted to the optium concentration that helps red-mud settlement, and the flocculant of interpolation is mixed with red mud is full and uniform, accelerated the sinking speed of red mud widely, the production capacity and the underflow that have improved the unit settling area contain admittedly.Thereby can finish the red mud separating, washing process with less settling area and less laterite washing number of times, reduce construction investment and operating cost.
Deep-cone settling groove in the past all only is provided with a feeding pipe as shown in Figure 1.The caliber of Venturi tube 2, mouth of pipe tapering and subsider feed pipe 1 are to be optimized design by computer and to draw by setting up Mathematical Modeling under the prerequisite in given inlet amount at the insertion depth of Venturi tube 2.After the specification of Venturi tube 2 is determined, the inlet amount of subsider is had strict requirement, when requiring the fluctuation range of inlet amount promptly to calculate greater than specified rate value ± 15%.Therefore, the shortcoming that a feeding pipe is set is the bad adaptability to the inlet amount fluctuation, can not satisfy the bigger production requirement of inlet amount fluctuation.
The red-mud settlement separating, washing is the subsequent handling of bauxite stripping.When adopting one group of red mud separating, washing and depositing groove and a stripping production line supporting, the fluctuation range of subsider inlet amount can satisfy the specification requirement of Venturi tube 2 chargings.When one group of red-mud settlement separating, washing deep-cone settling groove and two stripping production lines are supporting, because stripping production line normally substep is built, is gone into operation step by step, and when producing, because the stripping production line needs the periodic cleaning maintenance, have only in fact a production line the operation, the inlet amount of subsider only be about bio-occlusion quantitative 50%.When three stripping production lines were equipped with one group of red-mud settlement separating, washing, the deep-cone settling groove was built step by step, is gone into operation, and this moment, the fluctuation of mass flow was bigger.So the feeding pipe of former deep-cone settling groove can't satisfy the requirement of many stripping production lines.Thereby the group number of having to increase subsider satisfies the needs of many stripping production lines, causes construction investment and operating cost to increase.
The utility model content
The utility model is exactly that a kind of deep-cone settling groove feed system is provided in order to solve the problems of the technologies described above, purpose is to make it both have the dilution charging to contain admittedly and make flocculant and red mud starch full and uniform the mixing, quicken the effect of red-mud settlement, can guarantee again simultaneously that subsider is under the bigger operating mode of inlet amount fluctuation, high-efficiency and continuous stable operation, one group of red mud separating, washing and depositing groove can satisfy several stripping production lines build step by step the requirement of operation and aborning certain bar stripping production line stop because of the cleaning maintenance and cause the needs of inlet amount fluctuation.
In order to solve the problems of the technologies described above, the utility model is achieved in that deep-cone settling groove feed system, it comprises feeding pipe, blender, flocculant adder, and two or more feeding pipes and the blender that matches with it, flocculant adder wherein are set.
Described feeding pipe is to be made of feed pipe, the Venturi tube that is connected with feed pipe, and the other end of Venturi tube inserts in the central feeding tube.
The diameter of described each feeding pipe Venturi tube is identical.
The diameter difference of described each feeding pipe Venturi tube.
Described each feeding pipe is arranged on subsider center line homonymy.
Described each feeding pipe is arranged on subsider center line both sides.
Advantage of the present utility model and effect are as follows:
The utility model is by setting up feeding pipe on subsider, the suitable position at dark awl high rate settling is provided with two or more feeding pipes and facilities such as the blender that matches with it, flocculant adder as required.Making it both have the dilution charging contains admittedly and makes flocculant and red mud starch full and uniform the mixing, quicken the effect of red-mud settlement, can guarantee again simultaneously that subsider is under the bigger operating mode of inlet amount fluctuation, high-efficiency and continuous stable operation, one group of red mud separating, washing and depositing groove can satisfy several stripping production lines build step by step the requirement of operation and aborning certain bar stripping production line stop because of the cleaning maintenance and cause the needs of inlet amount fluctuation.Simplify equipment flowsheet, saved construction investment and operating cost.

Among the figure, 1, feed pipe; 2, Venturi tube; 3, central feeding tube.
The specific embodiment
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figures 2 and 3, two feeding pipes and the blender that matches with it, flocculant adder are installed on a dark awl high rate settling, feeding pipe is to be made of feed pipe 1, the Venturi tube 2 that is connected with feed pipe 1, and the other end of Venturi tube 2 inserts in the central feeding tube 3.The diameter of two Venturi tubes 2 can be the same or different, and these two Venturi tubes 2 are positioned at the one or both sides of subsider center line; Two Venturi tubes 2 enter the eddy flow direction of subsider feedwell can be identical or opposite.
Described feeding pipe also can be three, four, six.
