Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing foreign matter from waste rock wool insulating material.

[0002]

2. Description of the Related Art Conventionally, a rock wool heat insulating material is frequently used as a heat insulating material provided in a pipe of a plant or the like.
When the above rock wool insulation material is removed during inspection of pipes, repair, etc., it is disposed of as industrial waste.However, the rock wool mass itself removes foreign matter such as sand entering the gaps between fibers. Once removed, it can be reused. According to this, it is possible to greatly contribute to reduction of industrial waste and resource saving.

[0003]

As a method of removing foreign matter that has entered a gap between fibers such as a mat, a method of hitting with a hitting tool is effective. The above method is difficult to employ because the rock wool heat insulating material discharged as waste material is often a lump having an unspecified shape and size. The present invention has been made in view of the above-described problems, and has as its object to provide a method for effectively removing foreign matter that has entered between fibers of rock wool heat insulating material waste material.

[0004]

A method for removing foreign matter from a waste rock wool heat insulating material according to the present invention is slidable in a vertical direction, and a container having a bottom formed of a grid or a mesh is supported by an elastic stretchable member. A drive mechanism for intermittently performing a swinging motion of releasing the container after displacing the container against the elastic force of the elastic elastic member is provided, and the container containing the waste rockwool heat insulating material is shaken by the drive mechanism. In the process of moving, the gist is to rapidly rock the container by the repulsive force accumulated in the elastic expansion / contraction member to hit the waste rockwool heat insulating material against the lid plate of the container.

[0005] According to the above method, when the waste rock wool insulating material contained in the container is hit against the lid plate of the container, minute foreign matters such as sand that have entered the gaps between the fibers of the waste material are removed from the fibers. It is beaten out and taken out through a mesh or grid at the bottom of the container.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a plurality of containers 3 each having a grid 3a at the bottom are provided in a space below a top plate of a desk-type machine base including a top plate 1 and a support leg 2. A suspension plate 5 having a roller 5a is fixed to a supporting plate integrated with the plate 4, and the container 3 is made swingable up and down by a roller 5a and a guide rail 6 for guiding the same. A spring 8 is bridged between the plate 5 and the top plate 1, while a motor 9 is installed on the top plate 1, a bearing 10 is fixed on the back side of the top plate 1, and the pulley 11 on the motor side is connected to the pulley 11. The pulley 13 on the shaft 12 side of the bearing 10 is linked with a belt 14,
The shaft 12 protrudes radially, and a roller 15
When the tip roller 15 of the arm 16 hits the receiving plate 18 provided on the cover plate 17 of the container 3 while the shaft 12 is rotating, the plurality of integrated containers 3
Is depressed against the elasticity of the spring 8, and when released from the roller 15 thereafter, swings upward rapidly due to the repulsive force accumulated in the spring 8.

Therefore, if the container is filled with the waste rock wool insulating material, the acceleration generated when the container is suddenly swung upward by the accumulated repulsive force of the spring can be used.
The waste material is thrown upwards and strongly struck by the lid plate of the container, where small foreign matter such as sand that has entered the gap between the fibers of the waste material is struck out of the fibers and passes through the bottom grid 3a of the container. Taken out.

[0008]

1 to 3 show an embodiment of the present invention. FIG. 1 shows a foreign matter removing apparatus suitable for carrying out the method of the present invention, wherein A is a desk-shaped machine having a required height,
Denotes a top plate which is a main part of the machine base, and 2 denotes support legs at four corners of the top plate. In a space below the top plate 2, a container 3 made of synthetic resin having a grid 3a at the bottom is vertically swingably assembled.

In the illustrated example, four containers 3 are arranged,
Rollers 5a are respectively attached to four suspension plates 5 fixed to the attachment plate 4 and integrated with the connection attachment plate 4, and the roller 5a on the suspension plate side is engaged with the guide rail 6 fixed to the machine base side. A coil spring 8 functioning as an elastic expansion and contraction member is mounted between a pin 7 projecting from a lower portion of each of the suspension plates 5 and the top plate 1, whereby the four containers 3 are elastically moved by the springs 8. It is swingable up and down while being supported by.

On the other hand, a motor 9 is installed on the top plate 1, a bearing 10 is fixed on the back side of the top plate 1, and a pulley 11 on the motor side and a pulley 13 on a shaft 12 side of the bearing 10 are provided.
An arm 16 is attached to the shaft 12 so as to protrude in the radial direction and has a roller 15 at the tip.
When the plate 5 hits the receiving plate 18 on the cover plate 17 covering the container 3, the integrated four containers 3 are pushed down against the elasticity of the spring 8, and then released from the roller 15. When this occurs, the spring 8 is rapidly swung upward by the repulsive force accumulated in the spring 8.

Therefore, the waste material of the rock wool heat insulating material is put in the container 3, the opening is covered with a cover plate so that the waste material does not jump out, and the motor is started to rotate the arm 16, and During rotation, the tip roller 15 of the arm 6 hits the receiving plate 18 provided at the opening of the container,
The container 3 is pushed down to the alternate long and two short dashes line in FIG.
Is released and rocked upward rapidly by the accumulated repulsive force of the spring 8, and the acceleration generated at that time causes the waste rock wool insulating material to be thrown upward and hit against the cover plate 17 of the container with a strong force, Therefore, foreign matter such as sand entering the gaps between the fibers of the waste material is beaten out of the fibers, and is taken out through the bottom grid 3a of the container.

It is preferable that the vertical stroke for rocking the container is 100 mm or more, and the acceleration generated when the container is suddenly changed upward is 5 G or more. Experiments have shown that good results can be obtained for the removal of foreign matter that has entered.

The reason why the container is made of synthetic resin is that when a container made of a hard material such as metal is used, the waste material of the rock wool insulating material falls after being hit against the lid plate of the container and collides with the bottom of the container. This is to prevent the rock wool fiber from breaking and the fiber length to be shortened at the same time, and to minimize the impact when colliding against the bottom of the container so as not to damage the fiber itself. The opening of the bottom grid of the container is determined by the size of the lump of waste material, but in order to exclude rock wool small particles in addition to foreign matters, it is preferable to set the width to 3 to 5 mm and the length to 30 to 50 mm. preferable. In the above-described embodiment, a spring is used as the elastic expansion / contraction member, but this may be replaced with a rubber string.

[0014]

As described above in detail, according to the present invention, the object of the present invention is to deal with the waste of rock wool heat insulating material having an indefinite mass and shape having no specific shape and size. Foreign matter such as can be effectively removed.
