Description

  The present invention relates to a separation apparatus capable of accurately separating a mixture in which a relatively spherical spherical material and a non-spherical material such as a thin film are irregularly blended into the spherical material and the non-spherical material.

  For example, in order to sort a mixture in which spherical and horny materials are irregularly mixed into the sphere and the horny material, the feeder accommodated in the hopper extends horizontally from the lower end of the hopper. Through a vibrator attached to the lower surface side and supplied on an inclined sorting plate, and vibrates along the thickness direction so that the traveling wave travels above the sorting plate. The non-electrostatic vibration flow type that causes the spherical object on the sorting plate to fall to the lower position side of the plate and climbs while sequentially jumping the angular object to the higher position side of the sorting plate. A sorter has been proposed (see, for example, Patent Document 1).

  However, in the above-mentioned oscillating flow type sorter, in order to jump the square-shaped object and convey it to the upper side of the sorting plate, the conveying speed is increased unless the frequency applied to the sorting plate is increased. I can't. On the other hand, when the frequency applied to the sorting plate is increased, even the spherical objects once jump to the upper side of the sorting plate and then roll down to the lower side at a slow speed. As a result, in the above-mentioned oscillating flow type sorting machine, it takes a long time for one separation work to separate the mixture into a spherical object and a rectangular object, and the spherical object and the angular object after the separation are separated. Since each separation rate was also low, there was a problem that the separation efficiency was insufficient.

JP-A-6-198251 (pages 1 to 4, FIGS. 1 to 5)

  The present invention solves the problems described in the background art, and can separate a mixture containing spherical and non-spherical materials into the spherical and non-spherical materials in a relatively short time and efficiently. In particular, it is an object of the present invention to provide a separation device that can reduce the proportion of a small amount of spheres in non-spheres as much as possible.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the present invention uses a belt conveyor in which the feeding direction is obliquely upward from the floor side and can be vibrated, and on the source stream (downward) side of the upper belt of the belt conveyor, The idea is that the mixture of spherical and non-spherical objects is continuously dropped in the form of a waterfall (film) that spreads out so that they do not overlap each other as much as possible.
That is, the separation device of the present invention (Claim 1) is a device that separates a mixture of spherical and non-spherical materials into spherical and non-spherical materials, and the feed direction is obliquely upward with respect to the floor surface. A belt conveyor that is inclined and vibrated in the inclined posture, and a mixture supply means that drops and supplies the mixture of the spherical and non-spherical objects to the source stream side of the upper belt of the belt conveyor. It is characterized by that.

According to the separator, the following effect (1) can be obtained.
(1) The belt conveyor is disposed on the floor surface while rotating endlessly and inclined obliquely upward, and the entire belt conveyor is perpendicular to the surfaces of the upper belt and the lower belt. Alternatively, it can be vibrated along a direction along the surface, or along a one-dimensional to three-dimensional direction in which these are combined. In the separation device, even when the belt conveyor is not vibrating, when a mixture of spherical and non-spherical objects is dropped onto the inclined upper belt, the spherical objects roll on the belt surface and fall along the belt surface. On the other hand, the non-spherical object is sent to the discharge side together with the upper belt while being relatively stationary with respect to the belt surface due to friction with the belt. For this reason, even if the belt conveyor is not vibrating, a certain degree of separation is possible. However, if the non-spherical object is stationary on the belt surface so that the non-spherical object is covered on the spherical object or the spherical object does not roll downward, the spherical object can be rolled. However, since it rises with the upper belt, it cannot be separated from the non-spherical material. Therefore, by applying the vibration described above to the belt conveyor and moving the spherical object that has been prevented from rolling by the non-spherical object along at least one of the front, rear, left, and right directions, the spherical object is made non-spherical. It is possible to release the restraint by the object and roll it down on the belt surface of the upper belt. Therefore, since a considerable amount of spherical substances can be effectively separated from the above mixture, the mixture can be efficiently separated into spherical and non-spherical substances in a short time.

The spherical and non-spherical materials are, for example, spherical metal powders and irregularly shaped metal powders such as thin plate shapes, irregularly shaped metal pieces such as spherical metal pieces and plate shapes, spherical pebbles ( Examples include gravel) and irregularly shaped pebbles (gravel), or spherical and irregularly shaped ceramic pieces.
Moreover, the said spherical material and the non-spherical material are mix | blended at random in the said mixture.
Further, the spherical and non-spherical materials are either a desired material or product and the other is a waste material, or both are materials or products having different characteristics or applications. .
Further, the belt conveyor is obtained by winding an endless belt made of synthetic rubber, high-strength fabric, or a composite material of the fabric and rubber, around each circumferential surface of a pair of rollers separated from each other. At least one of the rollers can be rotated by a motor or the like.
In addition, the vibration applied to the belt conveyor is along at least one of the belt feeding direction, the width direction, and the thickness direction of the conveyor.

Further, according to the present invention, the mixture supply means includes a hopper for containing the mixture, a base end side located at a discharge port on a lower end side of the hopper, and a tip end side above the source flow side of the upper belt of the belt conveyor. A separating device (Claim 2) is also included, which is composed of a vibrable feeder disposed in a horizontal posture so as to be positioned in the position.
According to this, the mixture that has fallen in a lump shape from the discharge port on the lower end side of the hopper to the proximal end side of the feeder is subjected to vibration along the feeding direction of the feeder itself, and the like. After being uniformly dispersed without overlapping each other on the upper surface and being formed into a layered or thin film shape, it is supplied so as to fall in the form of a waterfall (film) on the source stream side of the upper belt of the belt conveyor. Therefore, the effect (1) can be obtained more effectively.

The hopper includes a hopper main body that has a polygonal pyramid shape such as an inverted conical shape or an inverted quadrangular pyramid whose diameter is reduced at the lower end side, and the discharge port that opens to the lower end side of the main body. The opening on the upper end side of the hopper body may be closed with a lid material.
Moreover, the said hopper is arrange | positioned at either the right or left side (side) in the source flow (downward) side of the said belt conveyor by planar view, for example.
Further, when the feeder is disposed with its feeding (longitudinal) direction inclined obliquely with respect to the source flow side of the belt conveyor in a plan view, the front end side of the feeder is a feeding direction of the upper belt in a plan view. On the other hand, it is cut obliquely so as to form a right angle.
In addition, the vibration applied to the feeder is along both the feeding direction of the mixture along the proximal end side and the distal end side of the feeder and the height (vertical, thickness) direction of the feeder.

Further, the present invention includes a separation device (Claim 3) in which a squeezing means for adjusting the amount of fall of the mixture is disposed at the lower end discharge port of the hopper.
According to this, since the mixture can be supplied from the hopper to the proximal end side of the feeder by a certain amount, the effect (1) can be stably obtained.
The throttle means is exemplified by a throttle valve that increases or decreases the area of the discharge port of the hopper, or a pair of throttle pieces that can approach and separate along the horizontal direction.

Further, in the present invention, a reflector on which the mixture falling from the front end side of the feeder collides is disposed between the front end side of the feeder and the source flow side of the upper belt of the belt conveyor. A separation device (claim 4) is also included.
According to this, the reflection in which the mixture that falls in the form of a waterfall (film) from the front end side of the feeder collides between the front end side of the feeder and the source stream (downward) side of the upper belt of the belt conveyor. A board is placed.
For this reason, many of the spherical objects in the mixture are strongly repelled when they collide with the upper surface of the reflector, and are greatly blown off toward the source (downward) side of the belt conveyor. Therefore, the spherical object falls to the source stream (downward) side of the upper belt than the non-spherical object. That is, since the repulsion (force) from the reflecting plate is large, the spherical object is thrown away. As a result, the spherical object is less likely to be disturbed by the non-spherical object after falling onto the belt surface, and rolls downward on the belt surface.
On the other hand, non-spherical objects, particularly those having a plate shape or a belt shape, are not blown away because the repulsion (force) from the reflecting plate is smaller than that of a spherical shape.
Therefore, since the spherical substance can be efficiently and reliably separated from the mixture, the effect (1) can be obtained more remarkably.
The reflection plate (repulsion plate) has an upper surface that is inclined so as to look up at the front end side near the front end side of the feeder. Can be jumped to a position on a relatively far surface on the source stream (downward) side, and the non-spherical object can be dropped on a relatively close surface on the source stream (lower) side of the upper belt.

Further, the present invention provides a vibration damping device that absorbs vibrations of the belt conveyor between a support body that rotatably supports a pair of rollers positioned at both ends of the belt conveyor in the feeding direction and the floor surface. Also included is a separation device (claim 5) in which the means are arranged.
According to this, the vibration control means which absorbs the vibration of the said belt conveyor is arrange | positioned between the support leg etc. which support the said belt conveyor arrange | positioned in the said inclination attitude | position on a floor surface, and this floor surface Therefore, it is possible to give stable vibration along the above-described direction to the belt conveyor that rotates endlessly. Therefore, the effect (1) can be obtained more reliably.
The vibration damping means is, for example, a vibration proof rubber, a coil spring, or a hydraulic damper.

Further, in the present invention, a separation device (a claim) in which a return pipe including suction means is disposed between a collection box disposed on the upper belt feed (upper) side of the belt conveyor and the hopper. Item 6) is also included.
According to this, since the separation work for a plurality of times can be continuously performed on the mixture for one lot, the effect (1) can be obtained more efficiently and significantly.
The suction means is an air pump, a vacuum pump, a cyclone, or the like.

In addition, according to the present invention, the plurality of belt conveyors are arranged in a posture inclined obliquely upward with respect to the floor surface, arranged in series and in parallel in a side view, and adjacent in a plan view. A separation device (Claim 7) is also included in which the ends of the upper belts of two or more belt conveyors overlap each other.
According to this, since a lot of spherical objects can be separated from the mixture by sequentially supplying the mixture of one lot to the plurality of belt conveyors arranged in series in the inclined posture, a high mixing rate is achieved. The non-spherical material can be automatically reached at a low mixing ratio efficiently. Therefore, the effect (1) can be obtained more efficiently and reliably.

In the case where the plurality of belt conveyors are arranged in series and parallel to each other in a side view, a collection box for collecting the spherical objects is individually arranged adjacent to the source stream side of each belt conveyor. In addition, a collection box for collecting the non-spherical material is disposed only near the lower side of the feed (upper) side of the belt conveyor located on the final end side.
In the case where a plurality of the belt conveyors are arranged, the feeding of the belt can be performed by making the inclination angle of the belt conveyor on the final end side larger than the inclination angle of the belt conveyor on the initial end side where the feeder is located. It becomes possible to reduce the mixing ratio of the spherical objects in the non-spherical objects conveyed to the (upper) side.

Hereinafter, modes for carrying out the present invention will be described.
FIG. 1 is a perspective view showing a separator 1 according to an embodiment of the present invention, and FIG. 2 is a side view thereof.
As shown in FIGS. 1 and 2, the separating device 1 includes a belt conveyor 20 whose feeding direction is inclined obliquely upward with respect to the floor surface F and capable of vibrating in the inclined posture, and the belt A mixture supply means 2 is provided for dropping and supplying the mixture hp of the spherical material bp and the non-spherical material sp to the source flow (downward) side 21 b of the upper belt 21 of the conveyor 20.
The spherical object bp is, for example, a spherical metal powder, and the non-spherical object sp is, for example, a metal thin film having an outer shape that is rectangular. These include, for example, a metal film (non-spherical material) and a metal powder such as a spherical shape that are formed simultaneously when a molten metal is dropped on the peripheral surface of a drum rotating at high speed to obtain a thin metal film. Is mentioned.

  As shown in FIG. 2, the belt conveyor 20 includes a pair of rollers 24 positioned at both ends in the feeding direction, an upper belt 21 and a lower belt 22 that are wound endlessly around these peripheral surfaces, and the pair of rollers 24. And a pair of left and right side frames 23 that support the lower and upper sides of the side frame 23, and a pair of support legs (supports) 25, 26 each having a different height. And a vibrating body 30 having a vibration generating device 31 disposed below the side frames 23.

The vibration generator 31 is an unbalanced mass type that performs rotational motion (a type in which a motor is rotated with an eccentric weight and generated by its centrifugal force, for example, a vibration motor), and a single-axis vibration hydraulic type (piston There are mainly three types, such as driving) and electrodynamic type (using a force generated by passing a current through a coil in a magnetic field). In the above-described unbalanced mass type vibration motor, the rotational movement surface is set parallel to the belt surface of the belt conveyor 20, or the rotational movement surface is perpendicular to the belt surface and parallel to the feeding direction. In order to increase the separation efficiency and the ultimate separation rate to the maximum extent according to the size and shape of the spherical object bp and non-spherical object sp, etc. Can be installed.
In the case of the hydraulic type and the electrodynamic type of the uniaxial vibration described above, the separation efficiency and the reach such as the width direction of the belt surface of the belt conveyor 20, the thickness direction, the feeding direction, or a combination thereof are also used. It can be installed in an optimal direction to increase the separation rate. Furthermore, it is possible to combine a plurality of the same or different types of vibration generators. As described above, the amplitude and the frequency can also be optimized.
Note that one or both of the rollers 24 can be rotated by a motor (not shown).

The inclination angle θ of the belt conveyor 20 with respect to the floor surface F is in the range of about 15 degrees to 40 degrees (for example, about 30 degrees).
Further, a lower end side of each of the support legs 25 and 26 and the four base plates 27 fixed on the floor surface F are connected via a coil spring (vibration control means) 17.
Further, a collection box 28 for collecting the spherical object bp is disposed adjacent to the source flow side 21b of the upper belt 21, and the non-spherical object is located just below the feed (upper) side 21a of the upper belt 21. A collection box 29 for collecting sp is disposed.

On the other hand, as shown in FIGS. 1 and 2, the mixture supply means 2 includes an oscillating body 6 having an inverted quadrangular pyramid-shaped hopper 3, a throttle portion 8 positioned at the lower end thereof, and an oscillating body 6. And a feeder 7 extending horizontally from above the source flow side 21b of the upper belt 21 of the belt conveyor 20. On the upper side of the hopper 3, a box-shaped lid 4 that closes the opening is disposed.
Further, as shown in FIG. 3 (A), for example, a throttle valve (throttle means) 9 surrounding the discharge port 3a of the hopper 3 and having a funnel shape as a whole is attached inside the throttle portion 8. Yes. The throttle valve 9 is made of a hard resin sheet or fabric having a funnel shape, and a string-like or strip-like throttle member 11 is wound around the outlet side 10 so that the fastening length can be adjusted.

Alternatively, as shown in FIG. 3 (B), a pair of left and right rotating shafts 12 are horizontally disposed directly under the discharge port 3a of the hopper 3, and the vertical cross section of each rotating shaft 12 has an oval or egg shape. A diaphragm means in which a pair of diaphragm pieces 13 are fixed symmetrically may be used. As shown in the figure, the discharge port 3a can be closed by bringing the tip portions 14 of the respective throttle pieces 13 into contact with each other. On the other hand, by rotating the rotating shaft 12 in the opposite directions, as shown in FIG. 3C, the tip portions 14 of the two throttle pieces 13 are separated from each other, and the mixture hp is formed into a film from the gap. It can be dropped to the feeder 7 side.
As shown in FIGS. 1 and 4A, the feeder 7 has a concave section in the vertical cross section, and the leading end side 7a is a feeding direction of the upper belt 21 of the belt conveyor 20 in plan view. Are cut obliquely in plan view so as to be orthogonal to each other.

Further, the vibrating body 6 vibrates the feeder 7 along at least one of the feeding direction of the mixture hp along the proximal end side and the distal end side 7a and the thickness (vertical) direction of the feeder 7. Let
In addition, as shown in FIG. 1, FIG. 2, FIG. 4 (A), (B), between the front end side 7a of the feeder 7 and the source flow side 21b of the upper belt 21 of the belt conveyor 20, A reflector 15 that collides with the mixture hp falling in the form of a waterfall (film) from the front end side 7a of the feeder 7 is arranged along the horizontal (lateral) direction.
The reflection plate 15 is made of a hard metal plate, and has an upper surface at least from both sides of the belt conveyor 20 so as to have an inclination angle of 40 degrees or more (for example, about 45 degrees) with respect to the floor surface F. It is fixed between the upper end sides of the paired left and right support pieces 16.
In addition, the said reflecting plate 15 is good also as a form attached between the said support pieces 16 so that the inclination-angle of an upper surface and height (level) can be changed arbitrarily.

Below, the effect | action of the separation apparatus 1 mentioned above is demonstrated.
In advance, one lot of the mixture hp is put into the hopper 3 and the above-described vibration is applied to the feeder 7 by the vibrating body 6 and the upper and lower belts 21 and 22 of the pelt conveyor 20 are rotated. And the vibration generator 31 is operated to apply the vibration described above to the entire pelt conveyor 20. That is, the vibration generator 31 uses a vibration motor (not shown), and depending on the mounting direction, the belt surface of the belt conveyor 20 has a one-dimensional direction to a three-dimensional direction (feed direction, thickness direction, width direction, In addition, it is possible to apply periodic vibration along a small rotational direction along the belt surface in a plan view and a small rotational direction along an arbitrary direction with respect to the belt surface.
In the above state, the throttle valve 9 or the throttle piece 13 is opened, and the mixture hp in the hopper 3 is sequentially dropped to the proximal end side of the feeder 7. As a result, the mixture hp is subjected to the vibration of the feeder 7 and becomes a film-like form in which the thickness gradually decreases from a lump-like form overlapping each other on the upper surface of the feeder 7 through a layered form.

The thin film (waterfall) mixture hp is shown in FIG. As shown in FIG. 2, it falls from the front end side 7 a of the feeder 7 onto the belt surface of the upper belt 21. In the middle of the fall, the mixture hp collides with the inclined upper surface of the reflector 15 as shown in FIGS. At that time, the spherical substance bp in the mixture hp is greatly bounced off on the belt surface on the source flow side (lower side) by the collision with the upper surface of the reflector 15 and falls on the belt surface of the upper belt 21. After rolling down, it enters the collection box 28.
Furthermore, when the mixture hp collides with the belt surface of the upper belt 21 that is vibrating while moving obliquely upward, as shown in FIGS. 4B and 5B, the mixture hp A part of the spherical object bp remaining on the upper part 21 is bounced larger, falls on the belt surface of the upper belt 21 and rolls down, and then enters the collection box 28.
That is, the reflecting plate 15 jumps the spherical object bp having a large repulsive force onto a relatively far belt surface on the source flow (lower) side of the upper belt 21 and relatively sends the non-spherical object sp to the upper side. By dropping onto a close belt surface, the phenomenon of overlapping the two is suppressed and separation is facilitated.

As a result, as shown in FIG. 5A, on the belt surface of the upper belt 21, the non-spherical object sp including the remaining spherical object bp and having a relatively weak repulsive force is placed in a thin film shape. Then, as shown in FIG. 2, the sheet is fed toward the feeding (upper) side 21a of the upper belt 21. The non-spherical object sp falls and is collected in the collection box 29 while being sent from the feeding side 21a to the lower belt 22 side.
As described above, in the separation device 1, when the mixture hp that has fallen into a film from the vibrating feeder 7 is collided with the upper surface of the reflector 15, some of the spherical objects bp jump off. Then, it falls onto the vibrating upper belt 21 of the belt conveyor 20, and another spherical object bp rolls to the source flow (downward) side 21b, and further, the non-spherical object sp containing the remaining spherical object bp. Is conveyed by the upper belt 21. In the middle of this, the spherical object bp is released from the restraint by the non-spherical object sp by the vibration of the belt conveyor 20, rolls down on the belt surface, and is recovered in the recovery box 28.
Therefore, according to the separation device 1, the effect (1) can be reliably obtained.

FIG. 6A is a side view showing a separation device 1 a which is an application form of the separation device 1.
As shown in FIG. 6A, the separation device 1a includes the same mixture supply means 2, a belt conveyor 20, and the like, and a support leg (not shown) on the collection box 29 on the downstream side 21a of the upper belt 21. Is arranged at a position higher than the floor surface F, and a return pipe 33 having an L shape in side view is connected between the inside of the collection box 29 and the lid 4 of the hopper 3. An air pump or vacuum pump (suction means) 34 is disposed in the middle. Further, vibration isolating rubber (vibration control means) 18 is individually disposed between the support legs 25 and 26 of the belt conveyor 20 and the floor surface F.

In the separation device 1 a, a certain amount of spherical matter bp is separated in advance in the same manner as described above, and the non-spherical matter sp including the remaining spherical matter bp accumulated in the collection box 29 is again returned to the hopper 3 through the return pipe 33. By re-introducing, the separation action can be continuously performed a plurality of times for one lot of the mixture hp.
Therefore, according to the separation device 1a, the effect (1) can be obtained more efficiently with less space. In place of the air pump 34 or the like, a cyclone (suction means) may be disposed above the lid 4.

FIGS. 6B and 6C are side views showing a separating apparatus 1b of different application forms.
As shown in FIGS. 6B and 6C, the separation device 1b is similar to the belt conveyor 20 and the mixture supply means 2 disposed on the left side in each drawing, the belt conveyor 20 adjacent to the right side thereof, and And two or more belt conveyors 20 that are inclined, the feed direction is in series, and the side view is parallel.

In the separating apparatus 1b as described above, the remaining spherical material bp is further separated from the mixture hp every time the downstream belt conveyor 20 is conveyed, so by selecting the total number of the belt conveyors 20, Depending on the lot of the mixture hp, the spherical material bp and the non-spherical material sp can be efficiently separated by one way.
Therefore, according to the separation device 1b, the effect (1) can be obtained with higher accuracy and reliability.

For example, the hopper may have a shape in which the outer shape has an inverted conical shape.
Further, the throttling means may be a single valve plate that slides in a horizontal direction directly below the discharge port of the hopper, or a pair of valve plates that approach and separate from each other.
Furthermore, a hydraulic damper may be used for the vibration damping means in place of the coil spring 17 and the vibration isolating rubber 18.
