Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a cleaner for a drum-shaped container that stores various types of powder, and relates to a drum cleaner that does not contaminate the surrounding area and workers by scattering of powder. .

(Prior Art) Traditionally, dye factories, pigment factories, etc. have handled large quantities of colored powders, and drum-shaped containers, generally called fiber drums, have been used in large quantities to store these powders. has been done. When using such a fiber drum to process powders of different types or colors, it is necessary to thoroughly clean the inside of the fiber drum.

(Problems to be Solved by the Invention) When cleaning the fiber drum, the particles are scattered violently, so the operator gets dirty easily and the surrounding area is significantly contaminated. Therefore, there is a need for a method for efficiently cleaning these fiber drums without contaminating workers and the surrounding area.

(Means for Solving the Problems) The present inventor completed the present invention as a result of intensive research in order to meet the above-mentioned demands.

That is, the present invention has a hollow cylindrical brush 10 with one or more rows of brushes 1 provided around the periphery and a rotating shaft 2 provided in the center, and a rotating shaft 2.
This drum cleaner is characterized by comprising a rotary power source 4 connected to a rotary power source 4, an intake pipe 5 for suctioning the inside of a hollow cylindrical brush 10, and a support base 6 for supporting these members.

(Example) Next, the present invention will be described in more detail with reference to the accompanying drawings that schematically show a preferred example of the present invention.

FIG. 1 is a perspective view showing a hollow cylindrical brush 10 constituting the main part of the drum cleaner of the present invention, and FIG. 2 is a sectional view schematically showing the entire drum cleaner of the present invention.

As shown in FIGS. 1 and 2, the drum cleaner of the present invention includes a hollow cylindrical brush 10 provided with at least one row of brushes 1 around the periphery and a rotating shaft 2 provided in the center;
The brush is composed of a rotary power source 4 connected to a rotary shaft 2, an intake pipe 5 for suctioning the inside of the hollow cylindrical brush 10, and a support base 6 for supporting these members.

The cylinder of the hollow cylindrical brush 10 shown in the first figure is a hollow cylindrical body made of any material such as iron, aluminum, or plastic, and its bottom and top are partially or completely open. Further, the central wall portion may have a large number of ventilation holes (not shown). With such a configuration,
As will be described later, powder from the inner wall of the fiber drum 7 can be efficiently sent to the dust collector without leaking to the surroundings.

The brush 1 provided around the cylindrical body is made of nylon,
It is formed by fixing a large number of filaments with good friction resistance, such as polyester, polypropylene, or steel, to the outer surface of a cylindrical body, and is preferably longitudinally elongated, but does not necessarily have to be continuous as shown in the figure. It is sufficient if sufficient friction can be applied to the inner surface of the Further, it is sufficient that the brushes 1 are provided in at least one row, but it is usually preferable to provide two to six rows. Also, such a brush 1 should be long enough to reach the inner surface of the fiber drum 7. Therefore, it is preferable to provide such a brush 1 not only around the cylindrical body but also at the top thereof. Such a hollow cylindrical brush 10 is fixed to the rotating shaft 2 by the rib 3, and the rotating shaft 2
Rotates due to the rotation of .

As shown in the second figure, the hollow cylindrical brush 10 has its rotary shaft 2 connected to a rotary power source 4, and is driven by the rotary power source 4, for example, a motor.
If the device is simple, it may be done manually. The rotation of the hollow cylindrical brush 10 also causes the fabric drum 7 to rotate, but the rotation of the drum 7 may be suppressed manually by the operator during work, or may be suppressed by any other arbitrary means. .

A suction pipe 5 is connected to the lower end of the hollow cylindrical brush 10, and is connected to an air suction source (not shown), for example, a dust collector, so that the hollow cylindrical brush 10 rotates.
The powder removed from the inner wall of the fiber drum 7 is sucked through the hollow cylindrical brush 10 by the flow shown by the arrow.

The hollow cylindrical brush 10 as described above is supported on a support stand 6, and the support stand 6 also supports the fiber drum 7 in a state in which the fiber drum 7 to be cleaned is inverted and placed on the hollow cylindrical brush 10. In order to prevent the covered fiber drum 7 from being sealed by the support base 6, the portion of the support base 6 covered by the fiber drum 7 is configured so that outside air can flow into the fiber drum 7. For example, the support base 6 may be shaped like a lattice or mesh.

(Function/Effect) According to the drum cleaner of the present invention as described above, the fiber drum 7 is placed over the hollow cylindrical brush 10 of the drum cleaner, and the hollow cylindrical brush 10 is rotated to remove powder. Since the inner wall of the fiber drum 7 to which the particles have adhered is strongly rubbed by the hollow cylindrical brush 10, the powder adhering to the inner wall is easily separated from the wall.
On the other hand, the inside of the hollow cylindrical brush 10 is constantly depressurized by the suction action of the dust collector, so air flows into the fiber drum 7 from outside the fiber drum 7 as shown in the figure, captures powder, and brushes the hollow cylindrical brush 10. Since the powder is guided to the dust collector through the suction pipe 5 and inside the dust collector 10, the powder does not flow out to the outside. Therefore, the workers and the working environment are not contaminated in any way.
