Description

Sedimentation-type centrifuge
The present invention relates to a kind of sedimentation-type centrifuge that solid particle and mixtures of liquids is separated into solid phase and liquid phase, particularly relate to a kind ofly with solid particle and two kinds of liquid phases, promptly the mixture of heavy-fluid and light liquid is separated into the sedimentation-type centrifuge of solid particle, heavy-fluid and light liquid.
Up to now, centrifuge or cyclone are used to solid particle and mixtures of liquids are separated into solid phase and liquid phase, and perhaps the mixture with solid particle and heavy-fluid, light liquid is separated into solid particle, heavy-fluid and light liquid.
The dish formula sedimentation type centrifuge (also claiming taper disc-type sedimentation type centrifuge) that is generally used for centrifugal sedimentation has the frustoconical video disc of some intervals one determining deviation configuration.Yet, when separating a kind of charging thin pulp of the solid liquid mixture with big solid content with a kind of dish formula sedimentation type centrifuge, the solid particle that gathers in the mixture is easy to stop up the gap between the video disc, makes the normal running of this dish formula sedimentation type centrifuge produce fault.In order to prevent the generation of this class problem, need to reduce the content of solid particle in the mixture, for example, then, utilize a dish formula sedimentation type centrifuge that this mixture is separated into solid phase and liquid phase by a spiral sedimentation centrifuge.Yet this practice needs the sedimentation-type centrifuge that is connected in series each other of two costlinesses.In addition, because this mixture must experience the centrifugal treating of the last twice, can be more relatively so sedimentation-type centrifuge consumed, be uneconomic.
The present inventor is in Japan 1,007, No. 732 patents (Japan Patent discloses No. 054961/75) and Japan Patent disclose and disclose a kind of sedimentation-type centrifuge that is used for solid particle and mixtures of liquids are separated into the solid-liquid two-phase for No. 152556/87, and a kind of with solid particle and two liquid phases, promptly the mixture of heavy-fluid and light liquid is separated into the sedimentation-type centrifuge of solid particle, heavy-fluid and light liquid.Disclosed sedimentation-type centrifuge can be referred to as the spiral sedimentation-type centrifuge of double inclined plane, and it has a butt bevel-type rotary drum that is used to discharge the solid particle of sedimentation.The inner wall surface of this rotary drum at first tilts with a bigger angle on the direction of discharging along solid particle with respect to the rotary drum center line, tilts with a less angle then.The double inclined plane inner wall surface of described rotary drum can make described solid particle move to the end of rotary drum reposefully, also can gently isolate liquid from solid particle.This drum structure can increase the inlet amount that rests in the centrifuge in the long time cycle.Therefore, the disposal ability of the separation accuracy of centrifuge and unit interval has increased.
The present inventor finds that in the practical application of described centrifuge, still there are many improvements that need said disposal ability, separation accuracy and power consumption aspect.As mentioned above more specifically, because the solid of sedimentation is easy to stop up gap between the video disc, all the more so when having big solid content in the charging especially, therefore, dish formula sedimentation type centrifuge often breaks down.This problem only can be by at first utilizing spiral sedimentation centrifuge to reduce solid content in the thin pulp, utilizes dish formula sedimentation type centrifuge to handle this thin pulp and achieve a solution then.Therefore, the sedimentation-type centrifuge of described two costlinesses or centrifuge need in series to connect mutually, owing to need to apply the centrifugal treating of the last twice in sedimentation-type centrifuge, power consumption is big.Although the spiral sedimentation centrifuge of double inclined plane by present inventor's invention only needs thin pulp once just can finish separation process by described centrifuge, but the practical application aspect of this sedimentation-type centrifuge, this sedimentation-type centrifuge do not resemble expectation than the series connection centrifuge have so much advantage, and in the application that requires to be separated accurately, disposal ability and energy consumption need further be improved.
The purpose of this invention is to provide a kind of sedimentation-type centrifuge, this centrifuge can overcome and separates the big thin pulp of solid content or mixture and cause the defective stopped up; When separating thin pulp, separation accuracy height, power consumption are low; And can only under a single cycle centrifugal action, separate more relatively charging thin pulp or mixture quite reliably.
Comprise according to sedimentation-type centrifuge of the present invention: one can be around the hollow circular cylinder of its central axis rotation; Carry the feed arrangement of an a kind of solid liquid mixture to the described hollow circular cylinder; One it have the first hollow frustum section of the inner wall surface that tilts with the said relatively center line of bigger angle, this first hollow frustum section have one with the larger-diameter openend of said hollow circular cylinder one end adjacency and one and the axial relative minor diameter openend of this major diameter openend; Second a hollow frustum section with the inner wall surface that tilts with a said relatively center line of smaller angle, this second hollow frustum section have one with the said first hollow frustum section than the openend of minor diameter openend adjacency and one and this openend opposing open end, this openend defines a discharge opening, the said second frustum section be positioned at such position with the first frustum section than the openend of minor diameter openend adjacency, the free surface of a cylindrical solid liquid mixture that promptly is same as or in this cylinder, forms when being lower than the hollow circular cylinder rotation; An auger conveyor that is disposed in described hollow circular cylinder, the first hollow frustum section and the second hollow frustum section, be used for carrying the solid of the isolated sedimentation from a solid liquid mixture of hollow circular cylinder, make it to arrive discharge opening by the first and second hollow frustum sections; Being disposed at hollow circular cylinder installs away from the weir plate (bank) that discharge opening one end is used for controlling from the said solid isolated liquid flooding of a liquid mixture; Discharge the drawing mechanism of said overflowing liquid; And at least one is installed on the said auger conveyor and the fin in the space between the pitch of auger blade, and this fin tilts with respect to said center line.
Described weir plate device can comprise that one is disposed at hollow circular cylinder and is used for controlling away from discharge opening one end and is disposed at hollow circular cylinder from first weir plate of the said solid isolated heavy-fluid overflow of a liquid mixture and one and is used for controlling second weir plate from the said solid isolated light liquid overflow of a liquid mixture away from discharge opening one end.Said drawing mechanism can be discharged the heavy-fluid and the light liquid of overflow respectively.For reaching the purpose of discharging liquid, also can use the method for casting aside liquid.
This Figure of description has disclosed the preferred embodiment of the invention with the form of example, by the following description of carrying out with reference to accompanying drawing, above-mentioned and other purposes of the present invention, reaches advantage especially and will become more obvious.
Fig. 1 is the longitudinal profile schematic diagram according to sedimentation-type centrifuge of the present invention;
Fig. 2 is the local longitudinal sectional drawing of the amplification of an auger conveyor and some fins in the sedimentation-type centrifuge shown in Figure 1;
Fig. 3 be according to another embodiment of the present invention an auger conveyor and the local longitudinal sectional drawing of the amplification of some fins.
As shown in Figure 1, this three phase separator has a feed pipe 1 that axially stretches into rotary drum 2 large diameter cylinder sections and opening, and rotary drum 2 comprises the cylinder of a hollow.When rotary drum 2 rotated at a high speed, typically a charging thin pulp to be separated or a solid liquid mixture of being made up of solid, heavy-fluid and light liquid was fed in the rotary drum 2 by feed pipe 1 and some holes 12.Under rotary drum 2 centrifugal action that rotation is produced at a high speed, the solid particle in the mixture radially moves towards the inner wall surface of export-oriented rotary drum 2.
Rotary drum 2 has a discharge openings end 4 around feed pipe 1, and this discharge openings end 4 defines discharge opening.Hold an auger conveyor 3 in the rotary drum 2, this auger conveyor 3 and rotary drum 2 arranged coaxial, and between 2 liang of opposite ends of rotary drum, axially extend.Auger conveyor 3 is to be different from the rotating speed rotation of rotary drum 2, and under the effect of auger conveyor 3, the solid particle that is deposited on rotary drum 2 inner wall surface is sent to said discharge opening.Then, solid particle is discharged this three-phase separator by discharge opening by passing away 5.
Rotary drum 2 has one partly around the double inclined plane part of auger conveyor 3 one ends configuration, and this end of auger conveyor is around feed pipe 1 configuration.This double inclined plane partly comprises one first frustum section, and this section inner wall surface tilts with the center line of a bigger angle with respect to rotary drum 2, and an end adjacency of the cylindrical section of larger-diameter openend of this section and rotary drum 2; This double inclined plane part also has one second frustum section, openend that the diameter of this section is bigger and the less openend adjacency of the first frustum section diameter, and the inner wall surface of this section tilts with the center line of a less angle with respect to rotary drum 2.The openend that the diameter of the second frustum section is bigger is positioned at such position, promptly is same as or formed cylindrical free surface of solid-liquid mixtures or Free Surface when being lower than rotary drum 2 rotation.The opposite end of this second frustum section is as said discharge end 4.
The second frustum section comprises that one is arranged near the discharge end 4 and its position is higher than the dry section 6 of the liquid level of rotary drum 2 said mixtures.
The solid particle of sedimentation is crossed dry section 6 before soon arriving discharge end 4, removes remaining liquid there basically from solid.
This three phase separator also comprises between some helical blade (blade) pitch that are disposed at auger conveyor 3 and the helical fin 7 of extension in parallel, and these fins 7 are installed on the said auger conveyor axle.Fin 7 promptly tilts with respect to the cylindrical free surface that rotates formation at a high speed owing to a solid liquid mixture with respect to the center line of rotary drum 2.The most mixtures that are added in the said separator are mobile along the helical blade and the fin 7 of auger conveyor 3, are subjected to resistance because of friction again simultaneously.Therefore, mixture is tending towards flowing around a near zone the inner wall surface of the rotary drum 2 of auger conveyor 3 and fin 7.Because near the zone the inner wall surface of rotary drum 2 is away from the rotation of auger conveyor 3 and fin 7, the mixture that flows in this zone bears very big centrifugal force, therefore can be separated efficiently.
This three phase separator can have one or more up to 20 helical fins.Distance between fin radially outer edge and rotary drum 2 inner wall surface is 5~100mm, and the thickness of each fin is 0.5~2mm.
Distance between the said fin should be as much as possible little, so that reduce the distance that solid particle must pass, i.e. settling height is so that increase settling efficiency.If the distance between the fin is too little, solid particle stops up the gap between the fin easily, has hindered solid and has discharged from the gap between the fin.Therefore, the distance between the fin should be determined according to the character of a pending solid liquid mixture.
Gu if the solid content of a liquid mixture is bigger, the distance between fin radially outer edge and rotary drum 2 inner wall surface is preferably selected greatly; Gu if the solid content of a liquid mixture is less, then the distance between fin radially outer edge and rotary drum 2 inner wall surface is preferably selected forr a short time, so that increase the work area of fin, improves separative efficiency.
Therefore, best bet is to obtain one group of auger conveyor that has only the fin of different radical lengths, selects a suitable auger conveyor according to the solid content of a handled solid liquid mixture.
Because centrifuge of the present invention or separator have the structure of double inclined plane sedimentation centrifuge, the free surface and the distance between rotary drum 2 inner wall surface of mixture that flows through rotary drum 2 is big.Therefore, the length of inserting the fin in the mixture in the rotary drum 2 is big, has improved separation accuracy and ability.
Relative rotary drum 2 center lines of said fin, promptly the optimized angle of this auger conveyor axle inclination should be little, so that reduce settling height, raising separative efficiency.But if angle is too little, the gap between the fin can be stopped up by solid particle, just solid particle can not be discharged the gap between fin.This angle preferred range should be 30~85 °.Fin surface is level and smooth, perhaps can have some level and smooth radial slots and fin, is used to increase surface area and must obtains separating property preferably.
The fin of another embodiment can be one group of thin plate that is installed on the said auger conveyor axle parallel to each other, the Free Surface that this group thin plate forms when the auger conveyor axle favours the mixture rotation radially stretches out, and the blade of said auger conveyor can be wound onto on the outer rim of these thin plates.
The centrifugal force that acts on the mixture that fin 7 inserts is less relatively.But, because distance between the fin 7 and the distance between fin 7 and the auger blade, be that settling height is little, heavy, light grains in the mixture have been quickened, sedimented particle for example shown in Figure 2 and the sedimentation of floating particle, showy and that take place subsequently coalescent, this will cause the increase of separation accuracy.Especially, if said mixture comprises solid, heavy-fluid and light liquid, caused coalescent owing to contacting with fin 7 so, heavy-fluid and light liquid can form interface shown in Figure 2, separate with higher separation accuracy.
The light liquid that has separated and passed rotary drum 2 overflows weir plate 8, discharges from separator by passing away 9.Equally, separated and the heavy-fluid of passing rotary drum 2 is overflowed weir plate 10, from separator, discharged by passing away 11.Like this, the effect of weir plate 8,10 is that control is light, the overflow of heavy-fluid.
Fig. 2 shows the blade and the fin 7 of the auger conveyor 3 of amplification.Fig. 2 also shows sedimentation and floats the motion mode of particle between fin 7.
Fig. 3 shows the auger conveyor 3 and the fin 7 of another embodiment.The blade of auger conveyor 3 and fin 7 are different from angle mentioned above with one, and promptly the incline direction with the blade of auger conveyor shown in Figure 2 and fin 7 is opposite.
For another embodiment, preferred construction is that fin is set like this, be that fin is one group of thin plate that is installed on the said auger conveyor axle parallel to each other, this group thin plate radially stretches out from the free surface that the auger conveyor axle favours the mixture the rotary drum 2 of rotation, and said auger blade is wound onto on the outer rim of these thin plates.
To narrate the comparative example 1 and 2 that separates a kind of incoming mixture with sedimentation-type centrifuge of the prior art below, and use the example of separating a kind of incoming mixture according to three phase separator of the present invention.
Comparative example 1:
Fly press in the fish meal factory is made incoming mixture to be separated with sardine, and makes this mixture drum sieve of flowing through, and its amount is 1000 liters/hour.Incoming mixture comprises the 30.8(body) oil of %, the 61.5(body) water of %, and the 7.7(body) solid of %.This incoming mixture is fed into one, and traditional to have internal diameter be that the monocline face three of the rotary drum of 250mm separates in sedimentation-type centrifuge.This incoming mixture is to be separated into light liquid, heavy-fluid and sediment under the condition of 3000G at 95 ℃, centrifugal force.This light liquid comprises the 2.5(body) % or water still less, the 2.0(body) % or solid still less, all the other are oil.This heavy-fluid comprises the 98.7(body) water of %, the 1.3(body) solid and the 0.83(of % be heavy) oil of %.It is heavy that sediment comprises about 70() water of %, 3.0(is heavy) oil of %, all the other are solid.
Said light liquid is that fish oil is sold by the further fine finishining of an awl dish formula sedimentation type centrifuge, heavy-fluid simmer down to protein concentrates, and sediment is by the drying machine drying.
Light liquid water content average out to 1.8(body by traditional three phase separation sedimentation-type centrifuge production) %, this is a big numerical value.The solid that sedimentation goes out under centrifugal action in the light liquid is the 2.0(body) %, this also is a big numerical value.Light liquid can not obtain as the fish oil product immediately.Oil content in the heavy-fluid is that 0.83(is heavy) %, the solids content that sedimentation goes out under centrifugal action in the heavy-fluid is the 1.3(body) %.These numerical value are also excessive, and heavy-fluid causes the obstruction of heating tube when concentrating.
Suppose incoming mixture only by traditional three phase separation sedimentation-type centrifuge processing once, in fact this three phase separation sedimentation-type centrifuge not can be used as three phase separator and uses.In order to make the light liquid that forms become the fish oil product, need to utilize subsequently awl dish formula sedimentation type centrifuge to light liquid fine finishining.When the heavy-fluid that produces concentrated, it caused heating tube to break down.
Comparative example 2:
Fly press in the fish meal factory is made incoming mixture to be separated with sardine, and makes this mixture by a drum sieve, and its amount is 3000 liters/hour.Incoming mixture comprises 15.6~31.5(body) oil of %, 3.2~12.1(body) solid of %, all the other are water.This mixture joins in the sedimentation-type centrifuge of a traditional double inclined plane three phase separation with rotary drum that internal diameter is 320mm and an auger conveyor that does not have fin.Incoming mixture is to be separated into light liquid, heavy-fluid and sediment under the condition of 3000G at 90 ℃, centrifugal force.It is heavy that light liquid comprises 0.15() water of %, the solid of trace, all the other be oily; It is heavy that heavy-fluid comprises 0.1~0.26() oil of %, the 0.3(body) solid of %, all the other are water; It is heavy that sediment comprises 1.8() oil of %, approximately 65(is heavy) water of %, all the other are solid.
Said light liquid has good quality, can deliver immediately as the fish oil product.Heavy-fluid and sediment utilize the method described in the comparative example 1 to handle.The protein concentrates that is produced by heavy-fluid can not cause that when concentrated heating tube stops up, and is being better than comparative example 1 described protein concentrates qualitatively.The rate of drying of the sediment in this example substantially exceeds the rate of drying of comparative example 1 described sediment.
Example:
The incoming mixture of using in the comparative example 2 joins three phase separator of the present invention with 5100 liters/hour inlet amount.The rotary drum that it is 320mm that this three phase separator has an internal diameter and an auger conveyor that comprises that six outer rims and said drum inner wall surface configuration are the fin in 20mm gap.The height of fin on the auger conveyor axle is 70mm, the 45 that tilts as shown in Figure 2, and configuration equidistantly between the pitch of described auger blade, and the pitch of this blade is 60mm.Incoming mixture is at 93 ℃, and centrifugal force is to be separated into light liquid, heavy-fluid and sediment under the condition of 3000G.It is heavy that light liquid comprises 0.12() water of %, the solid of trace, all the other be oily; It is heavy that heavy-fluid comprises 0.1~0.2() oil of %, the 0.3(body) solid of %, all the other are water; It is heavy that sediment comprises 1.8() oil of %, approximately 65(is heavy) water of %, all the other are solid.
Said light liquid quality is fine, can be immediately as a kind of fish oil product delivery.Heavy-fluid and sediment utilize method same in the comparative example 2 to handle.Concentrate the protein concentrates that forms by heavy-fluid and have the same good quality of protein concentrates described in the comparative example 2, and the rate of drying of sediment is faster than the rate of drying of sediment in the comparative example 2.
The three phase separator that the present invention example is used have with comparative example 2 in the substantially the same key dimension of double inclined plane three phase separation sedimentation type centrifuge used.But, owing in auger conveyor, dispose fin, the disposal ability of three phase separator described in the example of the present invention is 1.7 times of double inclined plane three phase separation sedimentation-type centrifuge (5100 liters/hour than 3000 liters/hour) in the comparative example 2, and as the fish oil of light liquid and all heavy than 0.15(than the purity height described in the comparative example 2 (water in the light liquid: 0.12(is heavy) % as the moisture weak solution of the protein concentrates of heavy-fluid) %; Oil in the heavy-fluid: 0.1~0.2(weight) % is heavier than 0.1~0.26() %).
Can inference, the existence meeting of fin 7 produces opposite effect to the stability on the arena face border between light, the heavy-fluid.But example mentioned above and the experimental result of comparative example have but shown the raising of separated light, heavy-fluid quality, and that this raising has proved is light, the existence on stable arena face border between the heavy-fluid.
Though describe in detail and disclosed embodiment preferred more of the present invention, should be appreciated that, under the situation that does not break away from claims spirit, still can make various modification and improvement.
