Description
Technical field
The present invention relates to paddle, relate in particular to the paddle being combined into by rigid blades and flexible sheets.
Background technology
Stirring is that two or more materials are placed in to the process with paddle, they being mixed again in container.Mixing nature is the most basic requirement; But for some, transmit the poor slurry being mixed by solid-liquid two-phase (solid-liquid two class materials) of agitation energy, the slurry from stirrer paddle away from but often can not be mixed evenly, even have the part that substantially can not mix and form what is called " dead band ".So, people are except strengthening agitation energy, for saving the energy, just also stirrer paddle has been carried out to various improvement, Granted publication number is exactly one of this class improvement for CN102191372B, name are called the Combined stirring paddle > > that < < improves manganese metal electrolyte extraction rate.The slurry that the prior art stirs is the ore pulp mixing for leaching the solid-liquid two-phase of manganese metal electrolyte.Its paddle is combined by rigid blades (rigidity leaf section) and flexible sheets (flexible leaf section), and rigid blades is fixed on the shaft by driven by motor, and flexible sheets is connected to the outside of rigid blades.The prior art utilizes that flexible sheets does in slurry ceaselessly " sweeps away " property shake and can make agitation energy transmit fartherly, has played destruction " dead band " and effect that more slurry is stirred.Defect overcoming traditional full stirrer paddle for rigidity, improves stirring efficiency (allowing more slurries be mixed as soon as possible) aspect, has really obtained certain effect.Yet, because its flexible sheets can only be carried out " sweeping away " after all, so agitation energy just can not be delivered to the above and below that sweeps away aspect substantially, so, during application the prior art, just have to increase the number of plies of its " built up blade ".Obviously, if the number of plies increasing not or interlamellar spacing arrange not accurate enough and cause the distant of certain two interlayer, will form ring-type " dead band " between two-layer and hindered the raising of stirring efficiency; If thoroughly eliminate ring-type " dead band " by which floor is established, its installation cost just can increase again more.
Summary of the invention
The object of the invention is, provide a kind of and can reliably improve stirring efficiency, installation cost is the paddle of lower hard and soft combination again.
The scheme that realizes described object has and possesses following two kinds of identical specified features.
One, be particularly useful for being stirred the paddle of a kind of hard and soft combination of solid material proportion less (not needing especially paddle that component is upwards provided) in slurry.Its aspect same as the prior art is, this paddle consists of the rigid blades being fixedly connected with shaft, the flexible sheets that is connected with rigid blades.Its improvements are, described rigid blades has at least two-layer up and down, and described flexible sheets is the band shape of vertical setting; This flexible sheets with the mode that described rigid blades is connected is, upper end is connected to overlap condition in the rigid blades on upper strata, and lower end is connected in the rigid blades of lower floor with overlap condition; The length of lap not between the rigid blades of described flexible sheets and levels is 1.2～1.5 times of distance between the lower edge of corresponding upper strata rigid blades and the upper edge of corresponding lower floor rigid blades.
Two, be particularly useful for being stirred the paddle of a kind of hard and soft combination of solid material proportion large (often needing paddle that component is upwards provided) in slurry.Its aspect same as the prior art is, this paddle consists of the rigid blades being fixedly connected with shaft, the flexible sheets that is connected with rigid blades.Its improvements are, described rigid blades has at least two-layer up and down, described flexible sheets be with vertical direction have 5 °～30 ° inclinations angle and the vertical component when stirring towards above the band shape of setting; This flexible sheets with the mode that described rigid blades is connected is, upper end is connected to overlap condition in the rigid blades on upper strata, and lower end is connected in the rigid blades of lower floor with overlap condition; The length of lap not between the rigid blades of described flexible sheets and levels is 1.2～1.5 times of distance between the lower edge of corresponding upper strata rigid blades and the upper edge of corresponding lower floor rigid blades.
From above-mentioned two schemes, all can find out, because upper and lower two ends are connected to respectively " length of lap not between the rigid blades of flexible sheets and levels; be 1.2～1.5 times of distance between the lower edge of corresponding upper strata rigid blades and the upper edge of corresponding lower floor rigid blades " in upper and lower two-layer rigid blades overlappingly, also, flexible sheets is not tauted and is relaxed state.So,, when paddle Stirring, can agitation energy be transmitted fartherly by the shake of flexible sheets equally.Again because flexible sheets is linked lower floor's rigid blades from upper strata rigid blades always, so just eliminated up hill and dale that ring-type of prior art " dead band ".Therefore, compared with prior art, the present invention can improve stirring efficiency reliablely.From above-mentioned two schemes, it can also be seen that, in common practical application, the present invention only needs upper and lower two-layer rigid blades just can meet the demands; Obviously, under the dark especially a few cases of the degree of depth of stirred vessel (the leaching groove that tank diameter or prior art are such), the number of plies that the present invention increases is few than prior art also.Therefore, compared with prior art, the present invention can also economy system cost.
Below in conjunction with accompanying drawing, the present invention is further illustrated.

The specific embodiment
Scheme one:
A kind of paddle of hard and soft combination (referring to Fig. 1,2), this paddle consists of the rigid blades being fixedly connected with shaft 3, the flexible sheets that is connected with rigid blades.In the present invention, described rigid blades 5 has at least two-layer up and down, and described flexible sheets 6 is the band shape of vertical setting; This flexible sheets 6 with the mode that described rigid blades 5 is connected is, upper end is connected to overlap condition in the rigid blades 5 on upper strata, and lower end is connected in the rigid blades 5 of lower floor with overlap condition; 5 of the rigid blades of described flexible sheets 6 and levels are the length of lap not, is 1.2～1.5 times of distance H between the lower edge of corresponding upper strata rigid blades 5 and the upper edge of corresponding lower floor rigid blades 5.
Scheme two:
A kind of paddle of hard and soft combination (with reference to figure 1,2,3), this paddle consists of the rigid blades being fixedly connected with shaft 3, the flexible sheets that is connected with rigid blades.In the present invention, described rigid blades 5 has at least two-layer up and down, described flexible sheets 6 be with vertical direction have 5 °～30 ° tiltangleθs and the vertical component when stirring towards above the band shape of setting; This flexible sheets 6 with the mode that described rigid blades 5 is connected is, upper end is connected to overlap condition in the rigid blades 5 on upper strata, and lower end is connected in the rigid blades 5 of lower floor with overlap condition; 5 of the rigid blades of described flexible sheets 6 and levels are the length of lap not, is 1.2～1.5 times of distance H between the lower edge of corresponding upper strata rigid blades 5 and the upper edge of corresponding lower floor rigid blades 5.
Special instruction, Fig. 1 and Fig. 2 are the schematic diagrames that the paddle of employing six straight leaf turbine types is drawn according to scheme one, because of the state of " flexible sheets 6 is vertical setting ", so, in figure upper and lower two-layer paddle and rigid blades 5 thereof upright projection direction see over against.For scheme two, state because of " flexible sheets 6 is with vertical direction 5 °～30 ° tiltangleθs ", so, the rigid blades 5 of upper and lower two-layer paddle just should stagger, and preferably adopt the rigid blades there is same inclination angle---due to those skilled in the art, only reading the text description of scheme two specifically constructs with regard to having known it completely, therefore Fig. 3 has only drawn out the sketch of each end face of rigid blades 5 of levels and the side of a flexible sheets 6 according to rotating from the side the mode of observing.It will be apparent to those skilled in that, flexible sheets 6, with respect to the tiltangleθ of vertical direction, can only stir according to reality the proportion of solid material in slurry, and the factor such as speed of agitator is determined.So, just only disclosed in this manual the scope of tiltangleθ.
Evidently, in above-mentioned two schemes, its shaft 3 should be connected to and be positioned at stirred vessel 1(tank diameter or leaching groove etc.) prime mover 2(motor of top etc.) output shaft on.Conventionally, when the upper and lower side of flexible sheets 6 is connected to the rigid blades 5 of levels with overlap condition, after pressing with pressing plate (do not omit and do not draw in figure), with conventional fasteners 7(screw, bolt or rivet) again they are fastened.
In conjunction with the understanding to beneficial effect of the present invention, those skilled in the art is also necessarily clear, implement the physical length (relax level) of the banded flexible sheets 6 when of the present invention, should be can allow them shake, and agitation energy can be transmitted is fartherly principle---because concrete length needs according to the actual physical parameter (density and viscosity) that is stirred slurry, the actual conditions such as speed of agitator or condition are determined, and this definite just those skilled in the art only can accomplish by limited routine test, so, also only disclosed in this manual a scope.
Further, for obtaining more significantly effect, the particular location that also can connect flexible sheets 6 makes improvements.Specifically: with the outer side edges of overlapping flexible sheets 6 upper ends of the rigid blades 5 on described upper strata, align with the outer end edges of the rigid blades 5 on corresponding this upper strata; With the outer side edges of overlapping flexible sheets 6 lower ends of the rigid blades 5 of described lower floor, align with the outer end edges of the rigid blades 5 of corresponding this lower floor.That is to say, allow flexible sheets 6 be positioned at this diameter of stirring paddle determine circle edge time, because obtaining herein maximum linear velocity, can make flexible sheets 6 shake more violently, also just can agitation energy be transmitted fartherly.In this case, even can also suitably reduce diameter of stirring paddle Φ, to save further energy cost and installation cost (with reference to figure 1).
Further say, for obtaining more significantly effect, the width of described flexible sheets 6 is 1/40～1/10 of described diameter of stirring paddle Φ.By evidence, when the width of flexible sheets 6 narrower time, shake is got up easily, but it is weaker to transmit the ability of agitation energy; When the width of flexible sheets 6 wider time, shake is got up difficulty a bit, once but shake gets up to transmit the ability of agitation energy, strong.In view of when implementing, those skilled in the art only just can determine the best by limited routine test, is at least the width of good flexible sheets 6.Therefore, also still only disclosed in this manual the width range of flexible sheets 6, in limited range of the present invention, all can obtain the little better effects of difference.
Those skilled in the art is in conjunction with above-mentioned disclosure, certainly clear: the material of flexible sheets 6 and the selection of thickness, should in the situation that ensuring sufficient intensity and normal service life, remove to select not too thick material, to guarantee can to occur shake when stirring.Aspect material, can select polytetrafluoroethylene (PTFE), neoprene, butadiene-styrene rubber, silica gel or PVC.
The present invention has passed through contrast pilot experiment, and for guaranteeing comparativity, two kinds of paddles all only have identical traditional paddle of rigid blades to transform with former.
The slurry being stirred is selected the ore pulp of leaching manganese metal electrolyte, the manganese carbonate breeze of preparing ore pulp be time processing out, each test, according to 10 tons of identical physical parameter preparation ore pulps, is then placed in them in leaching groove (stirred vessel).Leaching groove diameter is 5m, is highly 8m, and bottom is flat, and mineral syrup liquid height is 7m.
Before transformation, traditional paddle used is identical double-deck six straight leaf turbine impellers, diameter of stirring paddle 2m, and the distance of the ore pulp leaching trench bottom that lower floor's paddle distance is flat is 0.8m, paddle interlamellar spacing is 4.8m.Mode according to prior art transformation is that in the outer end of all rigid blades, all pressing from both sides its outermost end has two flexible leaf section 32(of eight triangle broach with reference to figure 4, is also flexible sheets); According to the mode of the present invention transformation, be to allow the outer side edges at flexible sheets two ends Shang Xia 6, align with the outer end edges of the rigid blades 5 of levels in (with reference to figure 2); And compared the effect difference of the flexible sheets 6 of two kinds of different in width simultaneously.
The polytetrafluoroethylene (PTFE) that flexible leaf section 32 in two kinds of transformations and the equal phase selection of flexible sheets 6 are same, thickness is 5mm.
The result is in Table 1 and table 2.
Note: represent the Combined stirring paddle that carries out above-mentioned transformation according to prior art at table 1 and table 2 " existing ".Above-mentioned transformation is carried out in " I " representative according to the present invention and flexible sheets 6 width are 1/10 the hard and soft agitatortype of diameter of stirring paddle Φ; Above-mentioned transformation is carried out in " II " representative according to the present invention and flexible sheets 6 width are 1/20 the hard and soft agitatortype of diameter of stirring paddle Φ.
Power consumption contrast when the extraction rate of table 1 manganese metal electrolyte is 85%
The extraction rate contrast of manganese metal electrolyte when table 2 rotating speed is 150rpm
From the result of table 1, can calculate, in the situation that the extraction rate of manganese metal electrolyte is identical, the present invention is maximum more capable of reducing energy consumption 10.03% than prior art, and leaching time has also shortened.
From table 2, in result, can calculate, identical at rotating speed, in the substantially suitable situation of energy consumption, the extraction rate of manganese metal electrolyte brings up to 91.2% from the average extraction rate of prior art from 87.6%.
Extraction rate due to energy consumption, leaching time and manganese metal electrolyte, is all directly determined by stirring efficiency.So, from the contrast of table 1 and table 2, can find out, with respect to prior art, stirring efficiency of the present invention is further improved again really.From the contrast of table 1 and table 2, it can also be seen that, while adopting the flexible sheets 6 of width in limited range of the present invention, all can obtain the effect of further raising stirring efficiency---because combination principle analysis can be inferred: in the situation that intensity and normal service life meet the demands, its width is that 1/40 the flexible sheets 6 of diameter of stirring paddle Φ can obtain the effect of further raising stirring efficiency equally, therefore just do not select the flexible sheets 6 of this width in pilot experiment subject to the foregoing.
