Technical field
The present invention relates to a kind of screening plant that in tank, utilizes difference in specific gravity to screen the wet type of mixture.
Background technology
As the screening plant of the mixture that has utilized difference in specific gravity, the screening plant of the wet type of floating, avaling by proportion official post mixture in tank is used in the various fields.
This wet type screening plant can be used in following field, for example when obtaining the wood chip of paper making raw material, from mixing grittiness, in the mixture of the anharmonic ratio weight of iron plate etc., this anharmonic ratio weight is separated as foreign matter, for also can reclaim effectively proportion than 1 big in gently than the wood chip of weight, salvage conveyer belt (conveyor) and in tank, be provided with, water from the behind portion attraction tank of this conveyer belt, and supply to the bottom of the vertical tube of the tank that deposits the anharmonic ratio weight, make in the vertical tube and produce upwelling, by upwelling will be deposited in the vertical tube in gently roll back than the wood chip of weight, it is picked up (with reference to patent documentation 1) with conveyer belt.
[patent documentation 1] spy opens clear 62-79858 communique
In addition, in the process field of discarded object, from the concrete (concrete) as construction waste, recovery proportion is that the aggregate of the anharmonic ratio weight more than 2.5 utilizes again.In the aggregate that this is recovered, mix plastic sheet is arranged, wood chip etc.In the plastic sheet in this mixture, mix acrylic resin is arranged (polypropylene resin) and polyvinyl resin (polyethylene resin) geometric ratio anharmonic ratio 1 little gently than weight, and vinyl chloride resin (vinyl chloride resin) geometric ratio anharmonic ratio 1 big in gently than weight.In addition, wet wood chip proportion is bigger than 1, gently mixes wherein than weight in its conduct.If use the wet type screening plant, screen aggregate in the light mixture from mixing to have this than weight, then have avale in gently sneak into aggregate than weight, make the problem of the screening deterioration in accuracy of aggregate.
In addition,, reclaim the plumbous shot that is scattered on the soil property place at trap field, from soil and the mixture that reclaims in the lump of shot, with shot as the anharmonic ratio weight, with soil as in gently than weight, screen shot accurately.
At the process field of above-mentioned discarded object and trap field etc., when adopting the wet type screening plant from mixture screening anharmonic ratio weight, gently sneak in the anharmonic ratio weight in big than 1 in order to prevent proportion than weight, as patent documentation 1 record, consider that the method that adopts is, gently push back in avaling with ascending current than weight, and pick up by conveyer belt, but, owing to also having, the anharmonic ratio weight that pushes back with ascending current is transmitted the possibility that band gets, be with the anharmonic ratio weight that gets not return in the tank in case be transmitted, just have the problem of the rate of recovery reduction of anharmonic ratio weight.
Therefore, problem of the present invention is, the rate of recovery of anharmonic ratio weight is reduced, and gently sneaks into the anharmonic ratio weight than weight in preventing.
Summary of the invention
In order to solve above-mentioned problem, the present invention attracts to rely on gently to separate than weight during upwelling floats by suction tube and removes, and utilizes deadweight that the anharmonic ratio weight that enters into suction tube is avaled simultaneously and turns back in the tank.
In view of the above, because the anharmonic ratio weight is not attracted but turns back in the tank, so the anharmonic ratio weight that will avale in this tank got final product as reclaiming in the past.
Formation as this invention is a kind of screening plant, the mixture that will screen is dropped in the tank, utilize its difference in specific gravity to screen anharmonic ratio weight in the described mixture of the bottom land that avales, wherein, in described tank, be provided with make the luminous upwelling generator tube of upwelling and be floated on because of this upwelling in the water suspending object from downwardly facing opening be attracted to the top suction tube, set the attraction of this suction tube, even it is avaled by deadweight so that described anharmonic ratio weight enters.
The attraction of this suction tube, because can be by the flow area area of suction tube, attract the decisions such as ability of flow velocity, suction pump, so will be by experiment, actual job etc. suitably sets them, even so that the anharmonic ratio weight enters in the suction tube, it avaled by deadweight.
For example, if make the flow velocity of attraction velocity ratio upwelling of suction tube slow, then the mixture that comprises the anharmonic ratio weight by upwelling rises, even this mixture is sucked into suction tube, because the flow velocity in the suction tube is slow, so within the mixture, the below of anharmonic ratio weight suction tube because deadweight is avaled.That is,,, but rely on the avale below of suction tube of deadweight, can carry out high-precision screening so the anharmonic ratio weight of being kicked up by powerful upwelling can be by weak attraction stream inspiration because attract the flow velocity of velocity ratio upwelling slow.
As allowing the flow velocity method slowly that attracts the velocity ratio upwelling, for example can consider, make the aperture area of described upwelling generator tube, littler etc. than the flow area area of the intake section of the suction tube that attracts to described top from the opening of described suction tube.Allow aperture area (flow area area) difference if so, then usually because flow out from the upwelling of the opening advantage of upwelling generator tube, so have contain the anharmonic ratio weight mixture therewith upwelling rise together and enter situation in the suction tube, but attract in the way at this, because attract the velocity ratio upflow velocity slow, so the anharmonic ratio weight can further not be sucked in the suction tube, but with the avale below of suction tube of deadweight.This flow area area difference is effective during the flow that flows same in upwelling generator tube and suction tube.
According to the such experiment etc. of successfully avaling with deadweight such as the anharmonic ratio weight that enters this intake section, consider flow velocity etc., thereby suitably set the length (with reference to the L of Fig. 2) of the intake section of suction tube.
If the opening of upwelling generator tube is the position that upwelling is produced, then any one in the tank can, but to set aptly by upwelling and make the position of being floated smoothly according to experiment, actual job etc. by the mixture of input tank.
The position of the opening of upwelling generator tube and the opening of suction tube relation according to settings such as experiment, actual jobs, makes two openings have suitable distance, angle and relative, is floated on suspending object in the water to allow to successfully to attract because of upwelling.In this case, the position relation that is preferably formed the whole of the mixture of removing the anharmonic ratio weight and has only the part of anharmonic ratio weight to be attracted.
In this structure, can be along the flow direction of described mixture, for example with vertical demarcation strip being separated into ordered series of numbers in the described tank, these respectively listing of being separated described suction tube is set respectively.
If so, because rectified, gently float in can making than weight is stable by the demarcation strip upwelling.
At this moment, with sieve the mixture of putting in the described tank is carried out size classes in advance, divided the mixture of size to put into each good row of described separation respectively these, can improve thus with regulation proportion is the screening precision of ramification point.That is, if mixture is measure-alike, then the buoyancy that bears by upwelling of this mixture about equally the poor of power because the deadweight that difference in specific gravity causes is avaled, in gently than the easy rising of weight, the anharmonic ratio weight will avale easily.
Also have, the buoyancy that the object that size is more little is subjected to is more little, but because the power of avaling brought of deadweight reduces greatly, so when not carrying out size classes, probably meeting and be attracted together than the big but little mixture of proportion of its size and manage attraction and to be discharged to the outside of undersized anharmonic ratio weight.
Therefore, if carry out size classes, can change the intensity of upwelling of each row, only according to the difference of proportion make each size the anharmonic ratio weight and in gently be separated to avale side and uplifted side than weight, with the influence that the difference that reduces above-mentioned size causes, improve the screening precision.
Also have, upwelling can be produced by a upwelling generator tube, also can the upwelling generator tube all be set at each row of described separation, perhaps whenever listing more than 2 the upwelling generator tube is set.The latter's situation, the opening of a upwelling generator tube will face the row more than 2.
Suction tube can be provided with a plurality of towards the flow direction of described mixture in turn.If so, the attraction of suction tube is towards the flow direction of mixture and improve (reinforcement) interimly, promptly, make the attraction upstream side height more mobile of the suction tube in downstream than mixture, thus, can change from each suction tube attract (seizures) to the proportion of object, can screen the different material of seizure proportion.The number of suction tube is suitably set according to the number of the object of the difference in specific gravity of catching.
At this moment, at described each suction tube the upwelling generator tube is set respectively, its setting means is the flow direction towards mixture, and the upwelling that each upwelling generator tube is caused is strengthened (upflow velocity is accelerated in turn) in turn, can float smoothly and attracts according to the proportion of catching thing thus.
For example, when being provided with 2 upwelling generator tubes, by the suction tube of front side (mixture flow upstream side) attract proportion than in the 1 big plastics etc. gently than weight, then, attract not attracted to the smaller anharmonic ratio weight of proportion of aggregate within the anharmonic ratio weight in the suction tube of front side etc. by the suction tube of rear side, can filter out following 3 classes thus: the very large anharmonic ratio weight of this proportion of metal of the iron that is attracted by the suction tube of front and back, copper, lead etc. not; The smaller anharmonic ratio weight of proportion of the aggregate that is attracted by the suction tube of rear side etc.; By the suction tube of front side attract in gently than weight.
In addition,, also can attract the suspending object that do not attracted, therefore can improve described screening precision by the suction tube of front side by the suction tube of rear side even do not change the attraction of each suction tube.
In addition,, mixture is floated and sent into each suction tube, can further improve the screening precision if the upwelling generator tube is set respectively with respect to described each suction tube.
Under this situation, the position relation of the opening of above-mentioned stream generator tube and the opening of suction tube, experiment, actual job etc., two openings are set at the distance that keeps suitable, angle and relatively, so that do not attract the object of required proportion as far as possible, can successfully attract to be floated on the suspending object of the required proportion in the water because of upwelling.
(not only comprise ellipse, also comprise rectangle if the opening that makes described upwelling generator tube and suction tube becomes the long hole shape that is long in the horizontal for the flow direction of described mixture respectively.With reference to Figure 14), then upwelling narrows down at the tank insied width, and clear and definite mobile generation is being arranged, and because attract also narrowed width on the flow direction of this mixture of stream, so that this sucking action also becomes is certain.
The length of this slotted hole is done suitably according to the range of relative horizontal length of the flow direction of mixture and tank and to be set.In addition, the width of slotted hole is also done suitably on the formation degree of considering upwelling, attraction degree basis and is set.
In these structures, between the described upwelling generator tube and suction tube in described tank, lower end side is set as outlet side and open inclination screen cloth (screen) towards the flow direction of described mixture, and make it downward-sloping, upper end side at this inclination screen cloth drops into described mixture, and described anharmonic ratio weight is avaled at the bottom of described tank from the outlet side of described lower end side.
If so, then online at inclined screen because the mixture that avales with group's state is subjected to confusing of upwelling and floats, thus in gently successfully separated than weight, the anharmonic ratio weight directly drops on this screen cloth and at the bottom of the screw clamp that avales simultaneously.That is, gently than becoming smoothly weight and separating of anharmonic ratio weight, and because the mixture that avales with this group's state can be run into upwelling, so can reduce the amount (water yield) (mixture is floated) of this upwelling.
At this moment, if below this inclination screen cloth, the opening of upwelling generator tube is located at the appointed positions of its incline direction, for example discharge distolateral, then only upwelling takes place in the zone of the part of tank in meeting, thereby gently be floated on the underwater in can making, can reduce the water yield of upwelling than weight.Under this situation, also can make upwelling generator tube opening in other positions below the inclination screen cloth.
Give the mechanism of described inclination screen cloth vibration by setting, can utilize upwelling positively to make to avale on screen cloth in gently float than weight, and optionally be attracted to suction tube, further improve the screening precision.In addition, the mesh that also can prevent screen cloth stops up.
By being provided with by the portion that retains of the mixture of the upper end side of the described inclination screen cloth of input, this retains between the portion in arrival, because under method of double differences effect and make the anharmonic ratio weight be distributed to downside, in gently be distributed to after the upside than weight, mixture can move to the upper end side of inclination screen cloth, so can by upwelling make be distributed in upside in gently successfully float than weight, be attracted pipe easily and attract.
At this moment, if the portion of retaining is linked to the inclination screen cloth,, therefore can promote to arrive this mixture that retains portion under this vibration effect then along with the vibration portion of retaining of this inclination screen cloth is also vibrated, make described anharmonic ratio weight be distributed to downside, in gently be distributed to the effect of upside than weight.
The present invention as above the bottom of the screw clamp that avales because the anharmonic ratio weight is not attracted is so the rate of recovery of anharmonic ratio weight improves.
