Description
Technical field
The present invention relates to a kind of attachment device of central transmission concentrator, particularly relate to a kind of constant-current stabilizer of central transmission concentrator.
Background technology
The central transmission concentrator that present people use is when normal operation, and slip enters behind the concentration basin and around concentration basin through feeding pipe and spreads, and material relies on the gravity of self to sink to gradually at the bottom of the pond of inclination in this process.Simultaneously the motor-driven running roller concentration basin upper along on the round platform around center rotating and drive crane span structure, rotating cage, harrow frame and rotate together, in rotation process, the material that is deposited at the bottom of the pond is scraped collection with the rake teeth of angle in the pond on the harrow frame, realize the concentrated of material, and the clear water after the clarification flows to reusable edible behind the clear water reserviors from the top downflow weir.But traditional thickener does not have constant-current stabilizer or only has water fender, slip directly trickles to periphery after entering concentration basin, in concentration basin, easily form eddy current, settled fine granular materials is stirred again, directly affect the deposition effect of material, cause the thickener inefficiency, cause the thickener huge structure thereby must increase thus concentrator, cost of investment increases, and also is unfavorable for energy-conserving and environment-protective.
Summary of the invention
The objective of the invention is provides a kind of efficient steady flow device that improves the thickener operating efficiency in order to overcome deficiency of the prior art.
For achieving the above object, the invention provides a kind of central transmission concentrator constant-current stabilizer, comprise feeding pipe, described constant-current stabilizer is comprised of external flow guiding cylinder and inner draft tube, described external flow guiding cylinder is communicated with feeding pipe, and external flow guiding cylinder inwall upper end is provided with radially dividing guide plate and inwall bottom and is provided with along described external flow guiding cylinder inwall and is screw type deflector; The edge of described inner draft tube bottom is connected by connecting plate with described external flow guiding cylinder bottom.
Described external flow guiding cylinder upper end and bottom are the drum of opening, and described inner draft tube is the cylinder of the horn shape that the upper end is little, the bottom is large.
Described feeding pipe is one or two, and described radially dividing guide plate is no less than two, and described connecting plate is no less than four.
Be provided with several vertical directions and evenly distributed oblong openings on the described radially dividing guide plate, described opening is no less than two.
Described radially dividing guide plate is arranged radially in the cylinder of external flow guiding cylinder, the outside of described radially dividing guide plate and external flow guiding cylinder inwall are fixed, and lower end and the deflector of described radially dividing guide plate are fixed.
The edge of described external flow guiding cylinder upper end is provided with the dilution mouth, and the number of dilution mouth is no less than four.
Beneficial effect of the present invention is: in the situation that do not change change behind the efficient steady flow device that former main structure of thickener uses central transmission concentrator of the present invention pulp flow to, reduce eddy current, reduce the sedimentation required time and shorten settling height, make slip directly enter sedimentary deposit, make it to reach the effect of deep layer pan feeding, advection sedimentation; In the situation that do not increase any power, use constant-current stabilizer of the present invention than not adopting thickener day of the present invention and process the raising of slip amount more than 30%; This constant-current stabilizer is particularly outstanding to reluctant high concentration, fine fraction slip especially.
Be described further below in conjunction with the efficient steady flow device of accompanying drawing to central transmission concentrator of the present invention.

The specific embodiment
Such as Fig. 2, Fig. 3 and shown in Figure 4, constant-current stabilizer 8 is comprised of external flow guiding cylinder 5 and inner draft tube 6, and external flow guiding cylinder 5 upper ends and bottom are the drum of opening, and inner draft tube 6 is the cylinder of the horn shape that the upper end is little, the bottom is large.External flow guiding cylinder 5 is communicated with feeding pipe 1, and feeding pipe 1 is one.External flow guiding cylinder 5 inwall upper ends are provided with radially dividing guide plate 2 and bottom and are provided with along external flow guiding cylinder 5 inwalls and are clockwise spiral type flow guide plates 3.Radially dividing guide plate 2 is arranged radially in the cylinder of external flow guiding cylinder 5, and radially the outside of dividing guide plate 2 and external flow guiding cylinder 5 inwalls are fixed, and radially the lower end of dividing guide plate 2 and deflector 3 are fixing.Radially dividing guide plate 2 is set to two, radially is provided with several vertical directions and evenly distributed oblong openings on the dividing guide plate 2, and opening is no less than two, and the opening of the present embodiment is set to three.The edge of inner draft tube 6 bottoms is connected by connecting plate 7 with external flow guiding cylinder 5 bottoms, and connecting plate 7 is no less than four, and the connecting plate 7 of the present embodiment is provided with 12.The edge of external flow guiding cylinder upper end is provided with and dilutes mouth 4, and the number of dilution mouth 4 is no less than four, and the dilution mouth 4 of the present embodiment is set to six, and the interior liquid level of the position of dilution mouth 4 and concentration basin keeps same level, and opening is a little more than liquid level.Because the ore pulp in the constant-current stabilizer 8 is different from the osmotic pressure of concentration basin internal upper part clear water, so concentration basin top clear water can enter constant-current stabilizer 8 by dilution mouth 4, slurries are diluted, help flocculating effect, accelerate sedimentation, reach optimum efficiency.
As shown in Figure 1, constant-current stabilizer 8 is hung on maintenance platform, and what install at constant-current stabilizer 8 tops is drive unit 10, what the below installed is rotating cage 9, rotating cage 9 is connected with harrow frame 12, and drive unit 10 11 is connected with walking on stage, and feeding pipe 1 is with constant-current stabilizer 8 and concentration basin is outside links to each other.
Material is by the feeding pipe 1 tangential external flow guiding cylinder 5 that flows into constant-current stabilizer 8, then should be rotated counterclockwise downwards in the time of between the external flow guiding cylinder 5 of slip arrival constant-current stabilizer 8 and the inner draft tube 6, but because the external flow guiding cylinder 5 of constant-current stabilizer 8 of the present invention is provided with radially dividing guide plate 2 and deflector 3, so slip can slow down flow velocity and change direction, cause slip from inner draft tube 6 to disperseing even, slowly outflow downwards all around; Also owing to having reduced eddy current, make slip directly enter sedimentary deposit simultaneously, shorten settling height, reduce the sedimentation required time, make it to reach the effect of deep layer pan feeding, advection sedimentation.
