Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing clogging of a trommel separator in which a trommel is screened while rotating.

[0002]

2. Description of the Related Art Conventionally, as a clogging preventing device for a trommel separator, there has been known a device provided with a motor-driven vibration exciter or a hammer which reciprocates as the trommel rotates.

[0003]

In these conventional examples, a shock is applied to a part of the trommel by a vibration exciter or a hammer to shake the entire trommel to drop the deposit.

However, according to this, there is a problem in that the farther away from the place where the impact is applied, the more difficult the clogging preventing action is.

[0005] In addition, the generation of noise associated with a strong shock becomes an unavoidable problem regardless of whether the vibrator or hammer is used.

Further, in the case of the vibration exciter, there is a problem that energy cost is required.

The present invention solves the problems of these conventional examples all at once. That is, an object of the present invention is to provide a device for preventing clogging of a trommel separator which can prevent clogging uniformly over the entire trommel, does not generate noise, and does not require any energy cost.

[0008]

In order to achieve the above object, the clogging prevention device of the present invention is constructed as follows.

The present invention according to claim 1 is a trommel separation device for sieving while rotating a trommel,
The vibrating member is provided so as to be rotatably in contact with the outer surface of the peripheral surface of the trommel and is installed substantially parallel to the trommel rotation shaft and is supported so as to be in contact with and away from the trommel surface.

According to a second aspect of the present invention, there is provided a clogging preventive device for a trommel separator, wherein a pair of arms rotatably supporting both ends of a vibrating member on a tip end side and a base end side of the arm are vertically swingable. And a supporting frame for supporting.

In the device for preventing clogging of a trommel separator according to a third aspect of the present invention, the arm is provided so as to extend from the support frame in a direction following the rotational direction of the trommel.

In the device for preventing clogging of the trommel separator according to the fourth aspect, the vibrating member is arranged in the vicinity of the substantially uppermost point of the trommel.

[0013]

Therefore, the clogging prevention device of the present invention operates as follows.

According to the clogging prevention device of the first aspect, the vibrating member comes into contact with, for example, a bolt protruding on the surface of the trommel, irregularities on the surface of the trommel, or an attached matter protruding from the mesh of the trommel as the trommel rotates. While repeating contact and separation, vibration is applied to the trommel to remove deposits. When the trommel makes one revolution,
The vibrating member gives vibration to the entire surface of the trommel.

According to the clogging prevention device of the second aspect, the vibrating member contacts the surface of the trommel by the arm.
Since they are provided so as to be separated from each other, each time the vibrating member hits a bolt or the like projecting on the surface of the trommel, the arm slightly swings up and down to give vibration to the trommel.

According to the clogging prevention device of the third aspect, since the arm extends in the direction following the rotation direction of the trommel, a large load is not applied to the arm from the rotating trommel. That is, if the arm is extended in the direction opposite to the direction of rotation of the trommel, the arm may be caught between the trommel and the trommel, and an unreasonable load may be applied to the arm. With the anti-clogging device, such a situation does not occur.

According to the clogging prevention device of the fourth aspect, since the vibrating member is arranged in the vicinity of the substantially uppermost point of the trommel, all or most of the weight of the vibrating member is applied to the trommel, and the vibrating member is excited. The magnitude of the shock when the member moves up and down and gives vibration to the trommel increases.

Here, the trommel 1 is a sieve which is formed in a drum shape and is rotatably provided. All or part of the peripheral surface is formed of a net or punch holes. In this example, the punch holes 15 are provided. Trommel 1 has a mounting table 7
It is rotatably supported on. Reference numeral 8 indicates a charging pipe for charging the object to be processed in the trommel.

The clogging prevention device 6 is shown in FIGS.
As shown in FIG. 3, a vibrating member 9 made of, for example, a cylindrical roller, which is installed on the outer surface of the peripheral surface of the trommel 1 substantially parallel to the trommel rotation axis X, and both ends of the vibrating member 9 are rotatable toward the tip side. A pair of arms 10 supported on the
It is provided with a pair of support frames 11 that support 0 in a vertically swingable manner on the base end side.

The vibrating member 9 extends between the both end faces of the trommel 1 in the longitudinal direction of the trommel 1, and is provided by an arm 10 so as to be in contact with and separated from the surface of the trommel 1. Therefore, the vibrating member 9 is, for example, the trommel 1
By hitting the bolt 14 protruding on the surface, the unevenness on the circumferential surface of the trommel 1 or the deposit protruding from the mesh of the trommel 1, the trommel 1 is vibrated to remove the deposit. Vibration is given to the entire circumferential surface of the trommel 1 with one rotation of the trommel 1. In addition, in the present embodiment, the vibrating member 9
The reason why the roller is roller-shaped is to prevent uneven wear.

Reference numeral 12 indicates a pin for rotatably supporting the vibrating member 9 on the arm 10. Also, reference numeral 13
Indicates a pin for supporting the arm 10 on the support frame 11 so as to be vertically swingable.

The support frame 11 is fixed to the mounting table 7 at both end surfaces of the trommel 1. Reference numeral 14 is trommel 1
The head of the bolt which fixed the punch plate which comprises the peripheral plate of this to both end surfaces is shown.

By the vibrating member 9 hitting, for example, the bolt 14 protruding on the surface of the trommel 1, the unevenness on the circumferential surface of the trommel 1 or the deposit protruding from the mesh of the trommel 1,
The arm 10 swings up and down as indicated by arrow C. As a result, the vibrating member 9 vibrates the trommel 1 and removes the deposits.

The reason why the arm 10 is provided so as to extend in the direction according to the rotation direction A of the trommel 1 in this embodiment is as follows. That is, if the arm 10 extends in the direction opposite to the rotation direction A of the trommel 1, the arm 10 is caught between the trommel 1 and an excessive load is applied from the trommel 1 to the arm 10. This is to avoid such a situation, because smooth rotation of the vibration member 9 may be hindered.

The reason why the vibrating member 9 is arranged in the vicinity of the substantially uppermost point of the trommel 1 in this embodiment is as follows. That is, all or most of the own weight of the vibrating member 9 is applied to the trommel 1, so that the vibrating member 9 moves up and down to give the largest possible shock when the trommel 1 is vibrated. Is.

However, the arm 10 is replaced by the trommel 1
Needless to say, the present invention also includes the one provided so as to extend so as to face the rotation direction A of No. 1 or the one in which the vibrating member 9 is arranged at a position other than the vicinity of the uppermost point of the trommel 1.

According to the clogging prevention device 6 constructed as described above, clogging is prevented by removing the deposits on the trommel 1 as follows.

The trommel 1 is rotated in the direction of arrow A by driving the motor 5. Then, the vibrating member 9 in contact with the peripheral surface of the rotating trommel 1 rotates following the arrow B. Then, the vibrating member 9 hits the bolt 14, the unevenness on the circumferential surface of the trommel 1 or the adhered matter protruding from the mesh of the trommel 1, so that the arm 10 swings slightly up and down as indicated by an arrow C, and the vibrating member 9 applies vibration to the surface of trommel 1. As a result, the deposit inside the punch hole 15 is removed. When the trommel 1 rotates once, the roller 9
Will apply vibration to the entire circumference of the trommel 1.

As described above, it is not necessary to give a violent impact such that the deposits on the entire trommel 1 are instantaneously dropped, and it is merely an impact to remove the deposits near the contact portion between the roller 9 and the trommel 1. . Therefore, no noise is generated.

The present invention is not limited to the above-described embodiments, but various modifications can be implemented. For example, the protrusions on the surface of the trommel 1 are not limited to the above-described bolts 14, irregularities on the outer surface of the trommel 1 or the deposits protruding from the mesh of the trommel 1, and the effects of the clogging prevention device 6 of the present invention can be obtained. Special protrusions may be provided for raising.

The vibrating member is brought into contact with the trommel surface.
The mechanism for supporting the space freely is not limited to the one attached to the tip of the swinging arm 10 as described above, and may be vertically movable along, for example, a long hole-shaped guide, and may be pressed against the trommel by a spring. Good.

Further, the vibrating member is not limited to a rotatable roller, and a non-rotating rod may be used.

[0035]

According to the present invention described above, the following effects can be obtained.

In the clogging prevention device according to the first aspect, the vibrating member applies vibration to the surface of the trommel while hitting bolts protruding from the surface of the trommel 1, bumps on the outer surface of the trommel or deposits protruding from the mesh of the trommel. , Remove the deposits. Each time the trommel makes one revolution, the vibrating member gives vibration to the entire circumference of the trommel surface. That is, it is possible to prevent clogging uniformly over the entire trommel. Further, since it is not necessary to give the trommel a strong impact that shakes the entire trommel, noise is not generated. Further, since it operates following the rotation of the trommel, there is no energy cost.

In the clogging prevention device according to the second aspect, a vibrating member is attached to the tip end side of the swinging arm.
Therefore, it is possible to install the vibrating member on the trommel with a simple structure so as to be freely contactable and separable.

According to the clogging prevention device of the third aspect, since the arm extends in the direction according to the rotation direction of the trommel, a large load is not applied to the arm from the rotating trommel. In other words, if the arm extends in the direction opposite to the direction of rotation of the trommel, the arm will be caught between the trommel and the trommel, and an unreasonable load will be applied to the vibrating member and the arm. However, such a situation can be avoided. Therefore, it is possible to reduce the failure rate and reliably prevent clogging.

According to the clogging prevention device of the fourth aspect, since the vibrating member is arranged in the vicinity of the substantially uppermost point of the trommel, all or most of the weight of the vibrating member is applied to the trommel. Therefore, the magnitude of the impact when the vibrating member gives vibration to the trommel can be maximized, and the effect of removing the adhered substances can be further improved.
