Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration separating device for separating an object accommodated in a separating device body by vibrating the separating device main body.

[0002]

In many thermal power plants, seawater is used as cooling water for condensers.
In this case, the shellfish often enters and attaches to the cooling pipe through which the cooling water (seawater) flows. Then, the shellfish thus adhered grows in the cooling pipe and closes the cooling pipe. Therefore, an operation of periodically removing the shellfish from the cooling pipe is performed.

As one of such removing operations, there is a method in which a spherical sponge is passed through a cooling pipe at a high pressure to peel off a shell. In this case, as shown in FIG. 7, a sponge 2 having a diameter slightly larger than the pipe diameter (inner diameter) of the cooling pipe 1 is used. And many such sponges 2
By passing through the cooling pipe 1, many shells 3 in the cooling pipe 1 can be peeled off at once.

By the way, if the sponge 2 taken out together with the shell 3 after passing through the cooling pipe 1 is discarded together with the shell 3 each time, it is wasteful and costly. Therefore, there was a demand to separate the sponge 2 and the shellfish 3.

Therefore, it is conceivable to sift the shellfish 3 and the sponge 2 according to their size. In this case, since the relatively small shell 3 among the shells 3 is considerably smaller than the sponge 2, the shell 3 can be sieved off by a sieve net. However, when the shellfish 3 which has grown to a full extent in the cooling pipe 1 is sieved by a sieve net, the sponge 2 having substantially the same size as the shellfish 3 passes through the hole of the sieve net, and the shellfish 3 and the sponge 2 And could not be separated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vibration separating apparatus capable of separating a plurality of kinds of objects according to their shapes, specific gravities, elasticity and other properties.

[0007]

SUMMARY OF THE INVENTION The present invention separates a plurality of objects contained in a main body of a separation device by vibrating the main body of the separation device by means of vibration imparting means. An inclined surface is provided in the main body so as to extend obliquely upward from the bottom portion of the separation device main body, and an object enters when the separation device main body is vibrated by the vibration imparting means. Among the moving objects, the object having a large amount of bounce due to the vibration of the inclined surface is configured to be dropped on the bottom portion of the main body of the separation device, and the object having a small amount of bounce is located on the inclined surface. And is configured to be discharged from the discharge port at the terminal end (claim 1).

According to such a configuration, the object moves upward on the inclined surface when the vibration is applied by the vibration applying means. At this time, among the objects moving on the inclined surface, the object that largely bounces is dropped to the bottom portion, and the object that bounces small proceeds on the inclined surface and is discharged from the terminal outlet. Therefore, it is possible to separate the object that bouncing due to the vibration from the object that bouncing largely. Such a difference in the amount of bounce is caused by a difference in specific gravity of the object, a difference in shape (flat and spherical), a difference in elastic force, and the like.

In this case, if a large number of holes are formed in the bottom portion of the separation device main body (claim 2), an object smaller than the size of the hole among the objects passes through the hole and is sieved. In addition, the object can be separated according to the size in addition to the separation according to the difference in the amount of bounce caused by the vibration, and the separation performance is improved.

Further, apart from the outlet at the end of the inclined surface,
Providing a discharge port for discharging the object left on the bottom portion of the separation device body (claim 3) makes it easier to take out the object remaining on the bottom portion of the separation device body to the outside.

The vibration imparting means includes a first vibration mode in which the object on the bottom portion of the separation device main body moves from the center to the outer periphery so as to spiral in one direction; And a second vibration mode in which the object moves from the center to the outer periphery so that the object swirls in the other direction, and when the first vibration mode is provided, the separation is performed. The object on the bottom portion of the device body enters on the inclined surface, and when the second vibration mode is given, the object on the bottom portion of the separation device body is discharged from the another outlet. It is good to be constituted as follows (claim 4).

According to such a configuration, when the object is separated by the difference in the amount of bounce caused by the vibration of the inclined surface, the vibration mode given by the vibration giving means becomes the first vibration mode. When the setting is performed and the object remaining on the bottom portion of the separation device main body is discharged, the vibration mode provided by the vibration providing means is set to be the second vibration mode. Thereby, the separation work and the discharge work of the target object can be reliably performed.

At this time, the vibration applying means is provided with a rotating shaft supported by a bearing housing provided in the separation device main body, and vertically separated from the rotating shaft with the bearing housing interposed therebetween. By changing the angle between the upper and lower unbalance weights, the vibration mode imparted by the vibration applying means can be changed into a first vibration mode and a second vibration mode. It is preferable to be configured to be changeable (claim 5).

If the angle between the upper and lower unbalance weights is automatically changed by a change in the rotation direction of the rotary shaft (claim 6), the rotation of the rotary shaft can be performed without interruption for a long time. Only by changing the direction, the vibration mode applied by the vibration applying means can be switched, so that workability is good.

In this case, at least one of the upper and lower unbalance weights is rotatably supported on the rotating shaft, and the first and second unbalance weights are attached to the rotating shaft or a member rotating integrally with the rotating shaft. The first and second position regulating members are arranged such that one of the first and second position regulating members according to the rotation direction of the rotating shaft abuts on the rotatable unbalanced weight and the unbalanced weight is moved. When configured to rotate integrally with the rotary shaft (claim 7), the angle between the upper and lower unbalance weights can be changed according to the rotation direction of the rotary shaft with a simple configuration.

Further, the first and second position regulating members are
When the position is adjustable (claim 8), the angle between the upper and lower unbalance weights can be freely changed in order to obtain a vibration mode that meets conditions such as the shape, size, and specific gravity of the object.

Further, a guide extending inward of the separation device main body from one of the two circumferential sides of the another discharge port is provided in the separation device main body, and the first vibration mode is applied by the vibration applying means. At this time, if the object on the bottom portion of the separation device body is configured to move along the guide so as to avoid the another discharge port (claim 9), in the first vibration mode, Since the object is no longer discharged from the outlet, the object can be stored in the separation device main body until the object is sufficiently separated. In addition, if a shielding member is provided on the side of the inclined surface to prevent an object with a small amount of splash from dropping to the bottom of the separation device body (claim 10), the separation by the amount of object bounce is provided. The effect is further improved.

The outer peripheral side of the inclined surface 43 is fixed to the inner peripheral surface of the upper cylindrical frame 17 by, for example, welding. Further, the starting end of the inclined surface 43 which is located substantially opposite to the on-mesh discharge port 22 is welded to the upper surface of the sieve mesh 20. The end of the inclined surface 43 located close to the on-net discharge port 21 is located above the upper surface of the sieve mesh 20 by a predetermined height. Thereby, the inclined surface 43 has a spiral shape (strictly, a part of the spiral) that is inclined obliquely upward from the start end to the end.

The upper end of the wall portion 44 is configured to protrude from the inclined surface 43 by a predetermined width, and the protruding portion 44a forms a shielding member. The lower side of the wall 44 is welded to the upper surface of the screen 20.

That is, the width dimension of the protruding portion 44a is set to be smaller than the amount of the object that largely rebounds due to the vibration of the inclined surface 43 and larger than the amount of the object that rebounds smallly. The upper cylindrical frame 17 has an inclined surface 4 of an inclined table 42.
A discharge port 45 is provided at the terminal end of the discharge port 3, and a discharge port body 46 is provided corresponding to the discharge port 45.

On the other hand, as shown in FIG. 3, the outer peripheral portion of the lower cylindrical frame 15 is received by a conical receiving portion 23 provided on the bottom surface of the lower cylindrical frame 15 through the sieve net 20. A net outlet (not shown) for discharging the target object to the outside is provided, and an outlet body 24 is provided in the outlet.

On the other hand, a motor 25
Is fixed, and a V-pulley 26 is connected to a rotation shaft 25 a of the motor 25. In addition, V
A pulley 27 is rotatably supported, and a V belt 28 is stretched between the V pulley 27 and the V pulley 26.

A rotary shaft 30 is connected to a drive shaft 27 a of the V pulley 27 via a drive spring 29. A coupling 31 is integrally provided at a lower end of the rotating shaft 30, and an upper end of the drive spring 29 is fixed to the coupling 31. The rotating shaft 30 is rotatably supported via a bearing (not shown) on a vibrating body housing 32 as a bearing housing fixed to the center of the lower surface of the vibrating body base 13.

An upper unbalance weight 3 is provided at the upper end of the rotating shaft 30 projecting above the vibrating body housing 32.
3 is fixed. Thereby, the upper unbalance weight 33 rotates integrally with the rotating shaft 30. On the other hand, a lower unbalance weight 34 is rotatably mounted at the lower end of the rotating shaft 30 projecting below the vibrating body housing 32 and above the coupling 31. The rotating shaft 30 and the upper and lower unbalance weights 33 and 34 constitute a vibration applying means, and vibrate the sieve body 14, that is, the upper cylindrical frame 17, the sieve net 20, and the inclined surface 43.

As shown in FIG. 4, the coupling 31 is provided with first and second position regulating members 35, 36. These position restricting members 35 and 36 serve to lower unbalance weight 34 and upper unbalance weight 33.
Are rotated integrally with the rotating shaft 30 with a predetermined angle between the rotating shaft 30 and the rotating shaft 30. The angle between the upper and lower unbalance weights 33, 34 means an angle formed by a straight line connecting the center of gravity of each of the unbalance weights 33, 34 and the center of rotation.

More specifically, position regulating members 35 and 36 are provided so as to be movable along long holes 37 and 38 provided in the peripheral portion of the coupling 31. The long holes 37, 38
Has an arc shape, and is symmetrically disposed with respect to a straight line B connecting the center of gravity of the upper unbalance weight 33 and the center of the rotating shaft 30.

As shown in FIG. 5, the position restricting members 35 and 36 (in FIG. 5, the second position restricting member 36
Only shown. ), Mounting plates 35a, 36a located on the back surface of the coupling 31, and rod-shaped contact portions 35b, 36b projecting from the upper surface of one end thereof. The holes of the mounting plates 35a, 36a and the slots 37, 3
8, the bolts 39a are inserted into the couplings 31 and tightened by the nuts 39b, so that the position regulating members 35 and 36
Fixed to Further, the position regulating members 35 and 36 can be moved by loosening the nut 39b.

When the rotating shaft 30 rotates in the direction of arrow A by driving the motor 25, the lower unbalance weight 34 contacts the contact portion 35b of the first position regulating member 35 and rotates integrally with the rotating shaft 30. . On the other hand, when the rotation shaft 30 rotates in the direction opposite to the arrow A by the drive of the motor 25, the lower unbalance weight 34 contacts the contact portion 36 b of the second position regulating member 36 and rotates integrally with the rotation shaft 30. .
In this embodiment, the rotation shaft 30 rotates in the direction of arrow A when the motor 25 rotates in the normal direction, and rotates in the direction opposite arrow A when the motor 25 rotates in the reverse direction.

Therefore, when changing the angle between the upper and lower unbalance weights 33 and 34 when the rotating shaft 30 rotates in the direction of arrow A, the first position regulating member 35 is inserted into the elongated hole 37.
Along with the scale 40 at a desired angle. On the other hand, when changing the angle between the upper and lower unbalance weights 33 and 34 when the rotating shaft 30 rotates in the direction indicated by the arrow A, the second position regulating member 36 is moved along the elongated hole 38 to obtain the desired position. Is fixed to the scale 40 at the angle of.

Here, the vibration mode of the sieve net 20 generated by the rotation of the upper and lower unbalance weights 33 and 34 together with the rotating shaft 30 by the motor 25 will be described with reference to FIG.

FIG. 6 shows the upper and lower unbalance weights 3.
The upper row shows the positional relationship between the upper and lower unbalanced weights 33 and 34 when viewed from above, and the lower row shows the relationship between the angle between the angles 3 and 34 and the vibration mode of the sieve net 20. The moving state of the object on the sieve net 20 is shown.

First, FIG. 6A shows a vibration mode when the lower unbalance weight 34 is positioned on the left side of the upper unbalance weight 33 at an angle of 90 degrees. At this time, the object on the sieve screen 20 moves so as to swirl in the direction of arrow A toward the center regardless of the rotation direction of the rotating shaft 30. The tendency of the object on the sieve net 20 to swirl toward the center in this manner becomes weaker as the angle between the unbalance weights 3 and 34 decreases, and eventually,
On the contrary, they tend to move toward the outer circumference.

FIG. 6B shows the case where the rotating shaft 30 rotates in the direction of arrow A and the angle between the unbalance weights 33 and 34 is approximately 60 degrees, or the case where the rotating shaft 30 is opposite the arrow A.
FIG. 6 shows a vibration mode when rotating in the direction and the angle is approximately 45 degrees. At this time, the object on the sieve screen 20 moves so as to swirl in the direction of arrow A from the center toward the outer periphery.

FIG. 6C shows a vibration mode when the positions of the upper and lower unbalance weights 33 and 34 coincide with each other. At this time, the object on the screen 20 is
It moves linearly from the center toward the outer peripheral direction irrespective of the 0 rotation direction.

On the other hand, when the lower unbalance weight 34 is located on the right side with respect to the upper unbalance weight 33, the raw material on the sieve screen 20 is displaced in the direction indicated by the arrow A opposite to the above-described position on the left. The rotation and the linear movement in the radial direction are combined. For example, FIG. 6D shows that the rotating shaft 30 rotates in the direction of arrow A and that the angle between the upper and lower unbalance weights 33 and 34 is approximately 60 degrees, or that the rotating shaft 30 is in the direction opposite to arrow A. And the vibration mode when the angle is approximately 45 degrees. At this time, the object on the sieve screen 20 moves in the direction of the arrow A toward the outer periphery.
Move in a spiraling direction.

Although not shown, the object on the screen 20 tends to move toward the center as the angle increases. Upper and lower unbalance weight 3
When the angle between the upper and lower unbalance weights 34 and 34 is 90 degrees, the material on the screen 20 is not affected by the rotation direction of the rotating shaft 30 as in the case where the lower unbalance weight 34 is located on the left side of the upper unbalance weight 33. It moves so as to spiral toward the center in the direction of the arrow A.

Accordingly, in this embodiment, since the guide 41 and the discharge port body 22 are inclined in the direction of the arrow A, FIG.
The vibration mode shown in FIG. 6D is the first vibration mode, and the vibration mode shown in FIG. 6B is the second vibration mode.

Next, the operation of the above configuration will be described. Here, an example in which the sponge 2 and the shell 3 shown in FIG. When the vibration is applied by the vibration applying means, the vibrating sieve device 10 having the above-described configuration provides the inclined surface 4 of the inclined table 42 disposed on the sieve net 20.
3 oscillates with the sieve screen 20. At this time, the inclined surface 4
3 vibrates slightly in the horizontal direction and vibrates slightly in the vertical direction.

Since the sponge 2 is light, elastic and easily deformed, the sponge 2 has such a property that even if the vertical vibration of the surface on which the sponge 2 is mounted is small, the sponge 2 rebounds relatively large. On the other hand, since the shell 3 has a relatively flat shape and is heavy and rigid, even if the mounted surface vibrates in the vertical direction, if the amplitude is small, the amount of rebound is small.

From this, in the present embodiment, the sponge 2 and the shell 3 are moved on the inclined surface 43 and separated by the difference in the amount of rebound. In addition, the shellfish 3 includes those having various sizes from those having substantially the same size as the sponge 2 to those having a smaller size. And the hole 20a of the said sieve net 20 is set to the magnitude | size which the sponge 2 does not pass.

First, when starting the separating operation, the first and second position regulating members 35 and 36 are fixed at predetermined positions. Specifically, for example, when the motor 25 rotates forward,
The position of the first position restricting member 35 is fixed so that the angle between the upper and lower unbalance weights 33 and 34 becomes an angle for imparting the first vibration mode shown in FIG. Sometimes both unbalance weights 33, 34
The second position restricting member 36 is fixed so that the angle between them becomes the angle at which the second vibration mode shown in FIG. At this time, the first and second position regulating members 35, 36
Is appropriately adjusted according to the object.

Then, the motor 25 is set so as to rotate in the reverse direction and is energized, and the object is fed into the sieve body 14 of the vibrating screen device in a vibrating state from the inlet 28. At this time, the coupling 31 is rotated in the direction indicated by the arrow A by the motor 25, so that the lower unbalance weight 34 comes into contact with the contact portion 36a of the second position regulating member 36 as shown by a solid line in FIG. You. Therefore, the upper and lower unbalance weights 3
The vibration mode given by 3, 34 is the first vibration mode shown in FIG.

As a result, the object on the screen 20 moves so as to swirl counterclockwise (toward the direction of the arrow A) toward the center. At this time, the shellfish 3 of the shellfish 3 smaller than the hole 20a of the sieve mesh 20 (hereinafter, small shellfish 3) passes through the hole 20a and is sieved. Further, among the objects, the objects located on the sieve net 20 (that is, the sponge 2 and the large shell 2) are:
It moves on the sieve mesh 20 in the direction opposite to the arrow A, and eventually enters on the inclined surface 43 from the start end of the inclined table 42 on the right side in FIG.

The object that has entered the inclined surface 43 is moved in the direction indicated by the arrow A by the vibration imparting means, and also vibrates in the vertical direction. To move towards. At this time,
Since the sponge 2 rebounds greatly due to the vibration of the inclined surface 43, when the sponge 2 moves on the inclined surface 43, the sponge 2 gets over the projecting portion 44 a and falls on the sieve net 20. On the other hand, since the amount of bounce of the shellfish 2 is small, the shell 2 does not climb over the projecting portion 44a and proceeds on the inclined surface 43 and is discharged from the discharge port 45 at the terminal end. At this time, the object passing near the on-net outlet 21 hits the guide 41, thereby causing the on-net outlet 2
1 is prevented from being discharged.

When the sifting operation of the small shell 2 and the discharging operation of the large shell 2 have sufficiently proceeded, the motor 25 is stopped and switched so that the motor 25 rotates forward.
The electric current is supplied again to vibrate the screen 20. At this time, the coupling 31 is rotated in the direction of arrow A, so that the lower unbalance weight 34 is in the first position as shown by the two-dot chain line in FIG.
Abuts on the contact portion 45a of the position regulating member 45,
The second vibration mode shown in FIG. 6B is provided. As a result, it does not pass through the holes 20a of the sieve screen 20 and the outlet 4
The object, that is, the sponge 2 remaining on the sieve mesh 20 because it was not discharged from the sieve 6, swirls clockwise (in the direction of arrow A) toward the outer periphery, and is discharged through the net discharge port 21. It is discharged from the outlet body 22.

At this time, the sponge 2 passing near the mesh outlet 21 moves to the mesh outlet 21 along the guide 41 provided in the mesh outlet 21 and is discharged from the mesh outlet 21. You. On the other hand, the small shell 2 dropped into the product receiver 23 after passing through the hole 20a of the sieve mesh 20 is discharged from the discharge port body 24 via the discharge port under the net regardless of the rotation direction of the motor 25.

According to this embodiment, the upper cylindrical frame 1
7, an inclined table 42 is provided to move an object on the screen 20 upward on the inclined surface 43.
Then, the object (sponge 2), which largely rebounds due to the vibration of the sieve screen 20, drops upward from the inclined surface 43 onto the sieve screen 20 when moving upward on the inclined surface 43, and the object that sputters small. (Shell 3) is inclined 4 without falling
3 and is discharged from the discharge port 45. Therefore, the target object can be separated by the difference in the amount of bounce caused by the vibration of the inclined surface 43.

Further, in this embodiment, the object 20 is formed such that a small object is first sieved off by the holes 20a formed in the sieve net 20. for that reason,
The object to be separated by the inclined surface becomes a certain size or more, and the difference in the amount of rebound between the sponge 2 and the shell 3 becomes larger, so that the separating effect is improved.

The upper cylindrical frame 17 has a net outlet 21.
Is provided, it is easy to take out an object which has not been sieved by the sieve net 20 and which has not been discharged from the discharge port 45.

Further, in this embodiment, the first vibration mode and the second vibration mode are configured to be provided by the vibration providing means, and the object is separated by a difference in the amount of rebound caused by the vibration of the inclined surface 43. In this case, the first vibration mode is set so as to be given, and when the object remaining on the sieve net 20 is discharged, the second vibration mode is set so as to be given. Therefore, the work of separating and discharging the object can be reliably performed.

Further, in the present embodiment, the first vibration mode and the second vibration mode are switched by changing the angle between the upper and lower unbalance weights 33 and 34. The angle between the upper and lower unbalance weights 33 and 34 is determined by the motor 25 (rotating shaft 3).
It was configured to change only by changing the rotation direction of 0). For this reason, two kinds of vibration modes can be obtained only by changing the rotation direction of the motor 25 without interrupting the work for a long time, so that the workability is good.

In addition, the change in the angle between the upper and lower unbalance weights 33 and 34 due to the change in the rotation direction is caused by the first and second position regulating members 3 provided on the coupling 31.
This can be realized with a relatively simple configuration in which the lower unbalance weight 34 is brought into contact with one of the 5, 36 corresponding to the rotation direction of the motor 25.

Further, the first and second position regulating members 3
5, 36 were provided so that position adjustment was possible. Therefore, the sieve body 1
A desired vibration mode can be obtained by freely changing the angle between the upper and lower unbalance weights 33 and 34 in accordance with the shape and specific gravity of the object to be put into the space 4.

Further, a guide 41 is provided in the net outlet 21 so as to prevent the object from being discharged from the net outlet 21 when the first vibration mode is applied. Therefore, the object can be retained on the screen 20 until the object is sufficiently sieved.

Further, a protruding portion 44a is provided on the inner peripheral side of the inclined surface 43. Therefore, of the objects moving upward on the inclined surface 43, only the object (large shell 3) having a large amount of bounce can be reliably dropped to the sieve net 20 side, and the separation effect is further improved.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. A configuration in which the net outlet 22 is omitted may be adopted. In this case, the vibration mode given by the vibration giving means can be configured to be only the first vibration mode. In this case, when the vibration is applied by the vibration applying means, only the shellfish 3 is discharged to the outside and the sponge 2 is left on the sieve net 20, but the effect that the configuration can be simplified can be obtained. Can be

Further, the guide 41 is omitted, and the mesh discharge port 21 is closed when the first vibration mode is given by the vibration giving means, and the mesh discharge port 21 is closed when the second vibration mode is given. An open lid may be provided. Sieve net 2
A configuration may be adopted in which a non-perforated plate is used instead of 0, and the target is separated only by a difference in the amount of bounce caused by the vibration of the inclined surface 43.

The first and second position regulating members are provided on the rotating shaft 30.
May be provided. Instead of fixing the upper unbalance weight 33 to the rotation shaft 30 and rotatably supporting the lower unbalance weight 34 on the rotation shaft 30, the upper unbalance weight 33 is rotatably supported on the rotation shaft 30. ,
The lower unbalance weight 34 may be fixed to the rotating shaft 30, or the upper and lower unbalance weights 33, 3
4 may be rotatably supported on the rotating shaft 30. In addition, as the object, the above-mentioned sponge 2 and shellfish 3
The present invention is not limited to this, and it is sufficient if a plurality of types of objects have different amounts of rebound due to small vertical vibrations of the placed surface.
