Abstract
The invention relates to the field of alumina production, in particular to slurry storage equipment used in the alumina industry, solves the problems that the baseplate of conventional storage equipment is susceptible to abrasion and the impeller of a discharging pump is susceptible to damage, and can prolong the service life of the storage equipment which is simple in structure and protect associated equipment. According to the storage equipment, guide skewed slots tilting down are formed in a tank body; the higher ends of the guide skewed slots are connected with a feed opening; the lower parts of the lower end outlets of the guide skewed slots correspond to anti-impact cones; the anti-impact cones are arranged at the bottom in the tank body and fixed on the baseplate of the tank body; slurry down from the guide skewed slots can flow onto the anti-impact cones, so that the slurry are prevented form impacting the baseplate of the tank body when flowing down. The discharge openings I of the storage equipment are formed in the bottom of the tank body and are higher than an emptying opening; meanwhile, screen stencils are arranged at the discharge openings II of the inner wall of the tank body. Thus, the steel balls, which become smaller due to abrasion, cannot flow out along with the slurry through the discharge openings I, so that the safe use of the discharging pump is ensured.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, but protection scope of the present invention not limit by embodiment.
As shown in Figure 1-2, slip storage facilities of the present invention mainly comprises: cell body 1, inlet point 2, guide skewed slot 3, erosion control cone 4, base angle swash plate 5, drain hole 6, deflation hole 7, outgate 8, discharging opening 9, inspection door 10 and diagrid net 11 etc., and concrete structure is as follows:
Storage facilities cell body 1 is fixed on ground; Inlet point 2 is arranged at the middle and upper part, side of cell body 1, opens inlet point 2 if two, then need symmetry to open, and slip can form convection current and avoid local buildup, scabs; Guide skewed slot 3 angled downward from horizontal in cell body 1 has constant slope (10-80 °), the high-end connection inlet point 2 of guide skewed slot 3, bores 4 corresponding below the low outlet of guide skewed slot 3 with erosion control; Erosion control cone 4 is arranged at cell body 1 inner bottom part and is fixed on the base plate 12 of cell body 1, the position of erosion control cone 4 need be determined by the position of guide skewed slot 3, to ensure that the slip that guide skewed slot 3 gets off can flow on erosion control cone 4, impact the base plate 12 of cell body 1 when so just can prevent under pulp flow, guide skewed slot 3 is consistent with the quantity of inlet point 2 with the quantity of erosion control cone 4;
Base angle swash plate 5 is arranged at the surrounding base angle place of cell body 1 inner bottom part and answers angled downward from horizontal to have certain gradient (10-80 °), can guarantee surrounding place no backup bottom cell body 1 like this; Drain hole 6 be arranged at cell body 1 bottom and as much as possible near the base plate 12 of cell body 1, be conducive to like this clear up time emptying cell body 1 in slip and precipitation; Deflation hole 7 is arranged at the top of cell body 1, and the steam in cell body 1 is discharged in its effect; Outgate 8 is arranged at the middle and upper part outside cell body 1, and outgate 8 communicates with in cell body 1, when cell body 1 slip is too much, discharges by outgate 8; Discharging opening 9 is arranged at the bottom of cell body 1, and it should higher than drain hole 6, and quantity can be determined as required; Inspection door 10 is arranged at the top of cell body 1, when it is convenient to patrol and examine in production, observes the slip situation of cell body 1 inside; Diagrid net 11 is arranged at discharging opening 9 place of cell body 1 inwall, and the grid pore size of diagrid net 11 can be determined as the case may be, can not be flowed out like this, and then guarantee the safe handling of discharging pump through the steel ball diminished that weares and teares by discharging opening 9.
When outside slip need flow into storage facilities cell body 1, slip enters from inlet point 2, through guide skewed slot 3, flow on erosion control cone 4, last slip flows automatically in cell body 1, because bottom cell body 1, surrounding is provided with base angle swash plate 5, so surrounding can not buildup in cell body 1.During discharging, slip flows out from discharging opening 9, and steam is discharged from deflation hole 7.When in cell body 1, the inlet amount of slip is greater than load, a part of slip can be discharged by outgate 8.During as overhauled storage facilities, can by drain hole 6 after emptying for the slip in cell body 1, then carry out overhauling.
