Abstract
The invention relates to a stirring tank which is applied to all kinds of stirring tanks and stirring devices in the alumina industry, in particularly to a stirring tank with baffle plates capable of reducing accumulating materials at the tank bottom. The stirring tank with the baffle plates capable of reducing the accumulating materials at the tank bottom comprises a tank body and the baffle plates, and is characterized in that included angles between straight panel at the middle upper portion of the baffle plates and the axial line of the tank body are between 0-90 degrees. The lower portions of the baffle plates are circular-arc-shaped and extend towards the bottom of the tank. The extending direction of the circular arcs is consistent with the rotating direction of material solution, and is concave downwards. The baffle plates are evenly distributed inside the tank body along the circumference. The stirring tank with the baffle plates capable of reducing the accumulating materials at the tank bottom can effectively strengthen solution flow speed and impact force on the bottom corners of the tank, and obviously reduce stirring power of the stirring tank and the phenomena of sedimentary accumulating materials and scabbing at the tank bottom.
Description
Technical field
The present invention relates to a kind of tank diameter, be applicable to all kinds of tank diameter agitating devices of aluminum oxide industry, relate in particular to a kind of tank diameter with reducing bottom land buildup baffle plate.Flow rate of liquid and the impulsive force of bottom land edge be can effectively strengthen, the precipitation buildup of trench bottom and the phenomenon that scabs significantly reduced.
Background technology
Present stage, in aluminium oxide hydrometallurgy production process, tank diameter often adopts oar formula agitating device and traditional straight-plate-type baffle plate.The effect of straight-plate-type baffle plate is in order to eliminate cylindrical tow-away zone, to increase mixed effect.But traditional straight-plate-type baffle plate is unfavorable for eliminating the trench bottom buildup.Although increase mixed effect because the straight-plate-type baffle plate can be eliminated cylindrical tow-away zone.But for trench bottom, due to the existence of straight-plate-type baffle plate, barrier effect has been given birth in miscarriage to liquid, has reduced the flow velocity of liquid, causes the solid particle in liquid not reach enough speed and produce precipitation.As shown in Figure 1, in groove, feed liquid under agitating device drives, produces two kinds of motions: along the circumferential direction rotatablely move; The vertical convection campaign, namely the middle part moves downward, and periphery is done ascending motion, and in whole groove, the feed liquid flow regime is the result of these two kinds of kinematic synthesis effects.After feed liquid rotation ran into baffle plate, the flow direction changed, and the direction that major part is walked around the backward deflection cell body of baffle plate center continues to rotate; Fraction rises along baffle plate, along with lifting height is gained in strength and weakened gradually, and constantly has feed liquid to walk around baffle plate to move in a circle.Because baffle plate is straight-plate-type, very weak along the feed liquid that baffle plate moves upward, the rate of climb is less than the solid particle decrease speed, and the solid particle of cell body bottom can not in time be taken away, and forms precipitation.
Summary of the invention
The present invention provides a kind of tank diameter with reducing bottom land buildup baffle plate for solving the problems of the technologies described above, purpose is feed liquid in tank diameter to be flowed rationally control, flow velocity and the intensity of strengthening groove bottom feed liquid overcome the problem that traditional straight-plate-type baffle plate is unfavorable for eliminating the trench bottom buildup.
To achieve these goals, the present invention is achieved in that a kind of tank diameter with reducing bottom land buildup baffle plate, comprise cell body and baffle plate, the middle and upper part straight plate shape of baffle plate and cell body axis angle are between the 0-90 degree, the baffle plate bottom is that circular arc is extended to trench bottom, the bearing of trend of circular arc is consistent with the feed liquid direction of rotation, is shaped as recessedly, and baffle plate is uniformly distributed along the circumference in cell body.
The circular arc starting point of described baffle plate bottom is A, and terminal point is B; The A point is 1500～8000mm apart from bottom land; The B point is 100～600mm apart from bottom land.
The radius of described circular arc is 1000～8000mm.
Described B point baffle plate tangential direction is level.
Advantage of the present invention and effect are as follows:
Adopted above-mentioned baffle plate, after agitating device drives the feed liquid setting in motion, along the circumferential direction rotation.After feed liquid ran into baffle plate, feed liquid was moved to oblique below along the baffle plate that tilts, and gradually becomes horizontal direction at the baffle plate circular arc portion; Because the circular arc baffle plate moves closer to trench bottom, the space between baffle plate and trench bottom is more and more less, and the flow stream velocity of flowing through herein becomes more and more faster, and trench bottom has been produced very strong scouring force, solid particle is rolled taken away, and has suppressed the generation of precipitation.The present invention can effectively strengthen flow rate of liquid and the impulsive force of bottom land edge, significantly reduces the tank diameter power of agitator, reduces the precipitation buildup of trench bottom and the phenomenon that scabs.

The specific embodiment
The below is described in detail by reference to the accompanying drawings to inventive embodiment, but the protection domain of invention is not limit by embodiment.
Embodiment 1
As shown in Figure 2, a kind of tank diameter with reducing bottom land buildup baffle plate of the present invention, comprise cell body 1 and baffle plate 2, the middle and upper part straight plate shape of baffle plate 2 and cell body 1 axis angle are between the 0-90 degree, and the present embodiment is 20 degree angles, baffle plate 2 bottoms are that circular arc is extended to trench bottom, the bearing of trend of circular arc is consistent with the feed liquid direction of rotation, is shaped as recessedly, and baffle plate 2 is uniformly distributed along the circumference in cell body 1, the circular arc starting point of baffle plate 2 bottoms is A, and terminal point is B; The A point is 1500～8000mm apart from bottom land; The B point is 100～600mm apart from bottom land, and the radius of circular arc is 1000～8000mm, and B point baffle plate tangential direction is level.
Embodiment 2
The middle and upper part straight plate shape of the baffle plate 2 in embodiment 1 and cell body 1 axis angle are 3 degree.The other the same as in Example 1.
Embodiment 3
The middle and upper part straight plate shape of the baffle plate 2 in embodiment 1 and cell body 1 axis angle are 85 degree.The other the same as in Example 1.
Embodiment 4
The middle and upper part straight plate shape of the baffle plate 2 in embodiment 1 and cell body 1 axis angle are 60 degree.The other the same as in Example 1.
Embodiment 5
The middle and upper part straight plate shape of the baffle plate 2 in embodiment 1 and cell body 1 axis angle are 45 degree.The other the same as in Example 1.
Operation principle of the present invention:
After agitating device drives the feed liquid setting in motion, along the circumferential direction rotation.After feed liquid ran into baffle plate, feed liquid was moved to oblique below along the baffle plate that tilts, and gradually becomes horizontal direction at the baffle plate circular arc portion; Because the circular arc baffle plate moves closer to trench bottom, the space between baffle plate and trench bottom is more and more less, and the flow stream velocity of flowing through herein becomes more and more faster, and trench bottom has been produced very strong scouring force, solid particle is rolled taken away, and has suppressed the generation of precipitation.The present invention can significantly reduce power of agitator, has simultaneously the effect of good removing bottom land buildup.
