Fig. 3 is the schematic flow sheet of embodiment of the invention granulate mixture separation method.
The specific embodiment
Seeing also Fig. 1, is an embodiment of granulate mixture piece-rate system of the present invention.
The present embodiment granulate mixture piece-rate system comprises pay-off, separator and gathering-device.
This pay-off is used for granulate mixture is sent to this separator, adopts conveyer belt 2 as pay-off in the present embodiment.
This separator comprises slide plate 3, gravity sensor 4 and hair-dryer 5.Slide plate 3 is positioned at the afterbody of conveyer belt 2 and downward-sloping, is used for receiving the granulate mixture 1 that this conveyer belt 2 sends.The gradient of adjusting slider 3 (it is comparatively suitable generally its gradient to be adjusted between 30 ° to 60 °) can make granulate mixture 1 through gravity sensor 4 time, has realized initial gross separation.Gravity sensor 4 and hair-dryer 5 are installed in the bottom of slide plate 3.Hair-dryer 5 is high pressure blow-gas device (such as the high pressure blow-gas rifle etc.), and by the electronic components such as the time relay, contactor, magnetic valve, startup and control button realize with gravity sensor 4 between be electrically connected.When the particle landing is arranged to gravity sensor 4; the coil of the voltage signal control time relay of gravity sensor 4 outputs, the coil of the time-delay close point control contactor of the time relay, contactor control magnetic valve; connect to start again and stop button the unlatching of control hair-dryer 5 or close.
This gathering-device is located at the below of this separator, and according to arranging placement apart from this separator mode from the near to the remote, is used for receiving the variable grain that separates through this separator, and it comprises dividing plate 6, collector 7 and collector 8.Collector 7 and collector 8 are emitted on the below of hair-dryer 5 successively.Dividing plate 6 is located between collector 7 and the collector 8, and the height at its top is no more than the height of hair-dryer 5.
The waste and old circuit board pulverized particles comprises the particle of various material usually, and the below is take the granulate mixture that contains plastics, aluminium, lead and copper as example, and the operation principle of the present embodiment granulate mixture piece-rate system is described.
Because the particle of unlike material has different gravity, particle gravity such as lead, copper is larger, and the acceleration that obtains in the downslide process is also larger; The particle such as aluminium, plastics gravity is smaller; the acceleration that obtains in the downslide process is also little; therefore adjusting slider 3 makes it have suitable gradient (it is comparatively suitable generally its gradient to be adjusted between 30 ° to 60 °); can make plumbous particle and copper particle plastic grain and the alumina particles less prior to gravity that gravity is larger in the granulate mixture arrive the slide plate bottom, realize the initial gross separation of granulate mixture.
Gravity sensor 4 adopts elastic sensing element to make the cantilevered shifter, drives electric contact with the energy-stored spring that adopts elastic sensing element to make, and can finish the conversion that changes to the signal of telecommunication from gravitational cue.When the particle of realizing initial gross separation was rolled into the position of the gravity sensor 4 of installing slide plate 3 bottoms downwards, gravity sensor 4 was converted to voltage signal with the gravitational cue of particle, the switch of control hair-dryer 5.According to the operation principle of gravity sensor, when plumbous particle and copper particle process gravity sensor 4, because these two kinds of particle gravity are larger, the distortion that the crystal in the gravity sensor 4 is caused is larger, and the output voltage of gravity sensor 4 is also large; And plastic grain and alumina particles gravity are less, and is less to the distortion that crystal causes, and the output voltage of gravity sensor 4 is also little.Therefore utilize the difference of gravity sensor 4 output voltages, can control the switch of hair-dryer 5.
When the less plastic grain of gravity and alumina particles during through gravity sensor 4, gravity sensor 4 receives its gravitational cues, and this gravitational cue is converted to less voltage signal, and control hair-dryer 5 is opened.Hair-dryer 5 begins to blow, and plastic grain and alumina particles are blown over dividing plate 6, falls dividing plate 6 back apart from slide plate 3 collector 8 slightly far away.When the larger plumbous particle of gravity and copper particle are rolled into gravity sensor 4, gravity sensor 4 receives its gravitational cue, this gravitational cue is converted to larger voltage signal, control hair-dryer 5 cuts out, plumbous particle and copper particle are not subjected to the effect of wind-force, naturally drop to apart from the near collector 7 of slide plate 3, thereby realize separation and the collection of variable grain.
The separation of the present embodiment granulate mixture only utilizes slide plate, gravity sensor and hair-dryer just can realize, and is not only simple in structure, do not need magnetic field, can be to environment yet, and operating cost is low, and separative efficiency is high.
Seeing also Fig. 2, is another embodiment of granulate mixture piece-rate system of the present invention.
In order further to increase the efficient that granulate mixture separates, the present embodiment granulate mixture piece-rate system is improved on above-mentioned basis embodiment illustrated in fig. 1.
The present embodiment granulate mixture piece-rate system comprises pay-off, separator and gathering-device.
Pay-off is conveyer belt 2.
This separator comprises slide plate 3, gravity sensor 4 and hair-dryer 5.Slide plate 3 is positioned at the afterbody of conveyer belt 2 and downward-sloping.The gradient of slide plate 3 is adjusted between 30 ° to 60 °.Gravity sensor 4 is installed in the bottom of slide plate 3.Hair-dryer 5 is the high pressure blow-gas device, and it is located at the below of slide plate 3, and by the electronic components such as the time relay, contactor, magnetic valve, startup and control button realize with gravity sensor 4 between be electrically connected.
Gathering-device comprises dividing plate 6, dividing plate 6 ', collector 7, collector 8 and collector 9.Collector 7, collector 8 and collector 9 are emitted on the below of hair-dryer 5 successively.Dividing plate 6 is located between collector 7 and the collector 8, and dividing plate 6 ' is located between collector 8 and the collector 9, and the height at dividing plate 6 and dividing plate 6 ' top is no more than the height of hair-dryer 5.
In the present embodiment, hair-dryer 5 wind-force sizes are adjustable.Utilize gravity sensor 4 control and regulation hair-dryers 5 to blow out the size of wind-force, plastic grain that can gravity is lighter separates with the alumina particles mixture.When plastic grain and alumina particles were rolled into the gravity sensor 4 of installing the tail, the gravity of plastic grain was less, and the voltage of gravity sensor 4 outputs is also little; And the gravity of alumina particles is slightly large, and the voltage of gravity sensor 4 outputs is slightly large, the size of the wind-force that the size control and regulation hair-dryer 5 that therefore can utilize gravity sensor defeated 4 to go out voltage blows out.When plastic grain was rolled into gravity sensor 4, the Control of Voltage hair-dryer 5 of gravity sensor 4 output blew out larger wind-force, made plastic grain cross dividing plate 6 and dividing plate 6 ' and fell in the collector 9 of slide plate 3 away from; When alumina particles was rolled into gravity sensor 4, the Control of Voltage hair-dryer 5 of gravity sensor 4 output blew out less wind-force, so alumina particles can only cross dividing plate 6, fell in the collector 8 of slide plate 3 close to; And when plumbous particle and copper particle were rolled into gravity sensor, gravitational cue was converted to larger voltage signal, and control hair-dryer 5 is for closing, and plumbous particle and copper particle can not be subjected to the effect of wind-force, naturally dropped to apart from the near collector 7 of slide plate.If therefore adopt the adjustable hair-dryer of wind-force size, can further improve the efficient that granulate mixture separates.
In above-described embodiment, also gravity sensor can be controlled the hair-dryer switch and be arranged to following mode: when the less particle of gravity is rolled into gravity sensor, gravity sensor is converted to less voltage signal with the gravitational cue of this particle, and the control hair-dryer cuts out; When the larger particle of gravity was rolled into gravity sensor, gravity sensor was converted to larger voltage signal with the gravitational cue of this particle, and the control hair-dryer is opened.Same, when hair-dryer is opened, also can be according to the size of the size adjustment wind-force of the gravitational cue of reception.Its principle is same as the previously described embodiments, repeats no more herein.
Also the hair-dryer of separator can be arranged to open mode in whole separation process.Because the quality of the particle of unlike material is different, when different particles tumbled to the slide plate bottom, speed was also different, under the effect of hair-dryer, present different parabolic paths, what have blows far, what have blows closely, and therefore different particles just falls into different collectors.Adopt this implementation, even in the less-than-ideal situation of granulate mixture initial gross separation effect, also can realize the separation of particle.The for example granulate mixture of the plumbous particle of a pile and a small amount of plastic grain, or the granulate mixture of a pile plastic grain and a small amount of plumbous particle because plastics are larger with plumbous gravity difference, starts hair-dryer, just the plastic grain in the granulate mixture can be blown away.
In addition, carry the pay-off of granulate mixture not only can adopt conveyer belt to slide plate, also can adopt hopper, when adopting hopper, hopper can be located at the top of slide plate.
The characteristic that the granulate mixture separator of the embodiment of the invention is different according to the particle gravity of unlike material in the granulate mixture, utilize slide plate to realize the initial gross separation of granulate mixture, recycling gravity sensor control hair-dryer is blown to the less particle of gravity, make the different particle of gravity fall into different collectors, just can realize the separation of granulate mixture, therefore do not need magnetic field, environment is not polluted, and simple in structure, and input and operating cost are low; Simultaneously between different collectors dividing plate is set, particulate blockage that can gravity is larger has further improved efficient and the precision of particle separation in the nearer collector of distance slide plate.
Seeing also Fig. 3, is an embodiment of particle separation method of the present invention.
In the present embodiment, as an example of the granulate mixture that contains plastics, aluminium, lead, copper example granulate mixture separation method of the present invention is described.
The present embodiment granulate mixture separation method comprises the steps:
Step S1: granulate mixture is sent on the slide plate by pay-off, and tumbles to the bottom from this slide plate top, realizes initial gross separation.
Step S2: the hair-dryer of slide plate below is blown to the particle of realizing initial gross separation that tumbles from this slide plate bottom, makes the variable grain in this granulate mixture fall into respectively different collectors.
In this step, hair-dryer is blown and can be realized in the following manner to the particle of realizing initial gross separation.
Implementation one:
Open hair-dryer, make it in the separation process of granulate mixture, keep the air blowing state.Because the quality of variable grain is different, when sliding into the tail, the speed of particle is also different, and particle presents different parabolic paths under the air blowing effect, and what have blows far, and what have blows closely, and therefore different particles can fall into different collectors.
Implementation two:
In the slide plate bottom gravity sensor is installed, is utilized this gravity sensor control hair-dryer.When particle was rolled into the position of the gravity sensor of slide plate bottom installing downwards, the gravitational cue that gravity sensor receives particle also was converted into the signal of telecommunication, the unlatching of control hair-dryer or close.
When the less plastics of gravity and alumina particles are rolled into gravity sensor, gravity sensor is converted to less voltage signal with gravitational cue, the control hair-dryer, blows to plastics and alumina particles apart from the slide plate collector slightly far away so hair-dryer begins to blow for opening.When the larger lead of gravity, when the copper particle is rolled into gravity sensor, gravity sensor is converted to larger voltage signal with gravitational cue, and the control blowning installation is for closing the effect plumbous, that the copper particle is not subjected to wind-force, naturally drop to apart from the near collector of slide plate, thereby realize the separation of variable grain.
Utilize the switch of gravity sensor control hair-dryer, also gravity sensor can be controlled the hair-dryer switch and be arranged to following mode: when the less plastics of gravity and alumina particles are rolled into gravity sensor, gravity sensor is converted to less voltage signal with the gravitational cue of plastics and alumina particles, and the control hair-dryer cuts out; When the larger lead of gravity and copper particle were rolled into gravity sensor, gravity sensor was converted to larger voltage signal with the gravitational cue of copper particle particle, and the control hair-dryer is opened.
Implementation three:
On the basis of above-mentioned implementation two, adopt the adjustable hair-dryer of wind-force size, utilize gravity sensor control and regulation hair-dryer to blow out the size of wind-force, granulate mixture is realized secondary separation.Take the less particle of gravity as example, if contain the particle of two or more unlike material in the less particle of gravity, this gravity sensor is according to the gravitational cue of the particle of the unlike material that receives, control to adjust the wind-force size of this hair-dryer, and the gravitational cue that receives is less, controls the wind-force that this hair-dryer blows out larger.Namely utilize the size of the wind-force that the size control high pressure blow-gas rifle of gravity sensor output voltage blows out.
In the present embodiment, when plastic grain was rolled into gravity sensor, the Control of Voltage hair-dryer of gravity sensor output blew out larger wind-force, and plastic grain is fallen in slide plate collector far away; When alumina particles was rolled into gravity sensor, the Control of Voltage hair-dryer of gravity sensor output blew out less wind-force, and alumina particles is fallen in the nearer collector of slide plate.If dividing plate is set between collector, the acceleration that the particle that then gravity is little produces under the effect that this hair-dryer is blown is larger, skips this dividing plate, falls into this dividing plate back collector far away apart from slide plate; The acceleration that the particle that gravity is large produces is little, can't skip this dividing plate, is therefore stopped by dividing plate, falls into this dividing plate front apart from the nearer collector of slide plate, can further improve the separative efficiency of granulate mixture.
Compared with prior art, granulate mixture separation method and the system of the embodiment of the invention, according to the different characteristic of variable grain gravity in the granulate mixture, utilize slide plate to realize the initial gross separation of granulate mixture, recycling gravity sensor control hair-dryer is blown to the less particle of gravity, it is fallen into apart from separator collector far away, and because the larger particle of gravity is not blown the effect of power, therefore fall into the collector nearer apart from separator, realize the high efficiency separation of granulate mixture, simultaneously between different collectors, dividing plate is set, particulate blockage that can gravity is larger has further improved efficient and the precision of particle separation in the nearer collector of distance slide plate; Perhaps the large particle of gravity is blown, also can reach same effect.This system architecture is simple in addition, does not need magnetic field in separation process, environment is not polluted, and therefore input and operating cost are low.
Above with reference to the accompanying drawings of the preferred embodiments of the present invention, those skilled in the art do not depart from the scope and spirit of the present invention, and can have multiple flexible program to realize the present invention.For example, the feature that illustrates or describe as the part of an embodiment can be used for another embodiment to obtain another embodiment.Below only for the better feasible embodiment of the present invention, be not so limit to interest field of the present invention, the equivalence that all utilizations specification of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
