In the device 5 of cylinder side feeding loose compound, the quantity of funnel 9 is identical with the quantity of corona electrode 10, and its discharging opening is facing to the space between corresponding corona electrode 10 and cylinder 3 sides.In the present embodiment, have the hopper 12 identical with hopper 9 quantity to the device 5 of cylinder side feeding loose compound, each hopper vertically is contained in the space between corresponding corona electrode 10 and cylinder 3 sides, is positioned at below funnel 9 discharging openings.The opening of each hopper 12 is towards the side of cylinder 3, along the equidistant dividing plate 13(Fig. 3 that is equipped with of hopper height), dividing plate is pressed the α angle and is installed, and the α angle is greater than the natural slope of loose compound, and the slope is about 45 °.
From the top down, next dividing plate 13 last dividing plate 13 grows same length.Dividing plate 13 is in order to the loose compound that distributes equably of the counterpart along cylinder 3 sides.
The hopper 12 of band dividing plate 13 is mainly used in loose compound most of under the situation of conductive particle, to prevent producing spark-over between corona electrode 10 and the cylinder 3 as receiving electrode.
By the direction of rotation (direction of rotation is represented with arrow on Fig. 2) of cylinder 3, the back at each corona electrode (Fig. 1,2) is provided with electrostatic attraction electrode 14, electrostatic attraction electrode is a metal tube, have the multiple layer of electrolyte, be contained on the insulator 11, with corona electrode 10 almost parallels.
Corona electrode 10 and electrostatic attraction electrode 14 be connected on have identical polar, on the power supply that DC voltage is U (indicating the binding post of power supply on the figure with symbol).
Press the direction of rotation of cylinder 3,, brush 15 is housed, in order to brush away the non-conductive particle on the cylinder side along the side of cylinder 3 in electrostatic attraction electrode 14 back.
The part side of corona electrode 10, electrostatic attraction electrode 14, brush 15 and therebetween cylinder 3 constitutes sort channel 16(Fig. 2).Therefore be provided with 8 sort channel 16 in the present embodiment of implementing eletric drum separator, sort channel quantity depends on the possibility that corona electrode 10, electrostatic attraction electrode 14 and brush 15 are set near the cylinder 3 of specified diameter.
Below cylinder 3, be provided with container 17,18,19 along its direction of rotation, these containers correspondingly are located in the flow process of conductive particle, non-conductive particle and both bonds, and number of containers depends on the quantity of loose compound size range of separation.For example, if require the loose compound of the particle that contains different conduction values is carried out sorting, just need several containers 17 of installing, the particle of conduction value maximum will flow in the nearest container of corona electrode.Conduction is worth the direction of rotation that corresponding smaller particles will flow into by cylinder 3 and is successively set in the container 17 of said vesse back.
Material for the ease of the size fractionated that draws off sorting, eletric drum separator has the device 20(Fig. 1 that draws off conductive particle, non-conductive particle and both bonds), this device is made of rotor 21 and circular passage 23,24,25: rotor 21 is contained in the casing 1, below the cylinder 3, and coaxial with cylinder 3, blade 22 is housed on the rotor 21; At each passage 16(Fig. 2) in the quantity of circular passage 23,24,25 identical with the quantity of container 17,18,19.Circular passage 23 communicates with all containers 17 by the otch on the rotor 21, and circular passage 24 communicates with all containers 18, and circular passage 25 communicates with all containers 19. Loop turn 23,24,25 is made of the dividing plate 27 that is provided with one heart on casing 1 base plate 26, in order to collect corresponding conductive particle, non-conductive particle and both bonds.Be provided with discharge port 28 in each passage in circular passage 23,24,25.The blade 22 of rotor 21 is arranged in circular passage 23,24,25, and the discharge port 28 of each passage is equipped with sleeve pipe 29,30,31, in order to draw off conductive particle, non-conductive particle and both bonds from eletric drum separator.
Cylinder 3, garden dish dispenser 8 and rotor 21 be ground connection all, and make it to rotate with the slip gear of charged motivation 32 and driving wheel 33, and driving wheel 33 interacts with rotor 21.
Sort channel 16(Fig. 2) with baffle plate 34(Fig. 1,2) separate, glazing door leaf 35 is housed, so that carry out adjustment work and assorting room is observed on the casing 1.
The working condition of eletric drum separator is as follows:
From high voltage source corona electrode 10 and electrostatic attraction electrode 14(Fig. 1,2 to separator) supply DC voltage U.At corona electrode 10 with as corona discharge electric field of generation between the cylinder 3 of receiving electrode, and between electrostatic attraction electrode 14 and cylinder 3, produce static electric field.Then, make motor 32(Fig. 1) connect electricity, motor by driving wheel 33 make rotor 21 together with cylinder 3 and garden dish dispenser 8 along 15 direction rotation from corona electrode 10 to brush.
Dispenser 8 is coiled in the garden that the non-conductive former loose compound and the former loose compound of conduction of need sorting in separator are sent into rotation by charging sleeve pipe 6 and sleeve 7, and compound is shifted to the periphery of dispenser under action of centrifugal force.The quantity delivered of compound is determined by the gap between sleeve 7 lower ends and the garden dish dispenser 8, can be set up when adjusting separator.Promptly enter all sort channel 16(Fig. 2 behind the edge of compound arrival garden dish dispenser 8) funnel 9 in, again by funnel 9(Fig. 1) discharge port directly enter the space between cylinder 3 sides and the corona electrode 10 and enter corona discharge region, or be distributed in the gap by hopper 12.Under first kind of situation compound in cylinder 3 sides, the effect lower edge of corona discharge electric field, static electric field and gravity with thin layer from distributions.Under second kind of situation, compound is introduced into hopper 12, along the dividing plate 13(Fig. 3 that tilts) evenly distribute, flow to cylinder 3 sides (Fig. 1) along dividing plate again.
In both cases, at each sort channel 16(Fig. 2) in, or in the corona discharge electric field, the particle of all loose compounds all obtains and the identical charging of corona electrode 10 polarity, these particles and corona electrode 10 are mutually exclusive and mobile towards the direction of ground connection cylinder 3, and press to the cylinder side.Simultaneously, the static electric field of the electrostatic attraction electrode 14 identical with corona electrode 10 polarity acts on the charged particle, impels charged particle to move to cylinder 3 directions.
Each particle discharges when contacting with cylinder 3 at once.Conductive particle repid discharge and throw off the cylinder side on cylinder 3.Conductive particle moves down under the gravity effect, and the static electric field of electrostatic attraction electrode 14 then makes these particles flow in the corresponding container 17 that is contained in the conductive particle flow process from cylinder 3.The non-conductive particle discharge of loose compound slowly many, therefore remain on the side of cylinder 3.The electric field of electrostatic attraction electrode impels these particles to remain on the surface of cylinder 3, and these particles brush away with brush 15 later on, and flowing into below the cylinder be container 19(Fig. 1 of non-conductive particle setting) in.
The bond of conductive particle and non-conductive particle, superfine conductive particle, or bigger non-conductive particle will not rest on the surface of cylinder 3 and flow in the container 18.As mentioned above, groups of grains poling in the container 18 is inconsistent, because loose compound flows to the side of cylinder 3 multilayer stream in assorting room, be not that all particles all are under the identical condition in the active region of corona electrode 10 and electrostatic attraction electrode 14, thereby cause producing different interactions with precipitation electrodes.Because loose compound is delivered to from above on cylinder 3 sides, mixture particle flows more anxious, thereby has improved the selectivity of separating.
When sorting contains the discrete material of conductive particle less (below 25%), for example when reclaiming molding sand, should use charging gear simple in structure 5, in this device, loose compound is directly sent in the space between cylinder 3 sides and the corona electrode 10 by funnel 9.When containing a large amount of conductive particle in the compound, between corona electrode 10, electrostatic attraction electrode 14 and cylinder 3, can produce periodic spark-over, this spark-over can be destroyed assorting room.
When in sorting is formed, containing the loose compound of a large amount of conductive particles, for example when handling titanium-zircon concentrate, adopt complicated feeding device 5, this device has added the hopper 12 of band dividing plate 13, can prevent to produce spark-over between corona electrode 10, electrostatic attraction electrode 14 and cylinder 3.When such feeding loose compound, mixture particle moves to the side of cylinder 3 along the tilt clapboard 13 of hopper 12, flow to cylinder 3(Fig. 1 with α angle (Fig. 3)) the side, and on aspect the rotation of cylinder 3, has tangential-velocity component, impel conductive particle in the zone of corona electrode 10 and electrostatic attraction electrode 14 back, to break away from the side of cylinder 3, and prevent the generation of spark-over.
Therefore, the loose mixture flow that contains conductive particle, non-conductive particle and both bonds is to the side as the cylinder 3 of receiving electrode, under the acting in conjunction of each electric field that corona electrode 10, electrostatic attraction electrode 14 and brush 15 cause, divide to go into 8 sort channel 16(Fig. 2) in, thereby, utilized cylinder 3(Fig. 1) whole side, improved the productivity ratio of separator significantly.In addition, also can adopt the similar method that is adopted with existing cylinder separator,, promptly add the length and the garden circular velocity thereof of swift 3 to improve its productivity ratio.
Conductive particle, non-conductive particle and both bonds enter the corresponding annular passage 23,24,25 from the discharge port of corresponding container 17,18,19, driving lower edge passage 23,24,25 at the blade 22 of rotor 21 moves to discharge port 28 directions, by corresponding sleeve pipe 29,30,31, draw off thus from separator.
This device for discharging 20 is very compact, and can not make the structure complicated of separator, and all revolving members of separator all by motor 32 transmissions, have so just been simplified the maintenance of this eletric drum separator.
Like this, the productivity ratio of the eletric drum separator of recommendation is greatly improved under the situation that does not strengthen its size.
