Description

  The present invention relates to a cleaning device for a cylindrical filter to which dust is attached.

  Such a cylindrical filter is used, for example, in a process for producing a raw material of a resin master batch (pigment compound). FIG. 5 schematically shows the process. In order to manufacture the raw material of the master batch, a mixing apparatus 1 having a stirrer 1a is provided, and resin pellets are charged therein. Further, a dry color of the powder is fed from a charging unit 1b provided at the top of the mixing device 1 (see arrow). The raw material of the master batch is manufactured by mixing the dry color and the resin pellet.

  On the other hand, since the dry color to be charged is powder, not all is charged into the mixing apparatus 1, but a part of the dry color rises to the surroundings. Therefore, the dust that has risen as dust is collected by the dust collector so as not to deteriorate the working environment. That is, the duct 2 is disposed above the mixing device 1 and collected by the dust collector 4 through the dust collecting pipe 3. A cylindrical filter 5 is attached in the dust collector 4, and dust is collected on the outer surface of the filter 5. Air containing dust sucked from the duct 2 passes from the outer surface portion of the filter 5 to the inner surface portion through the filter portion, and the air from which dust has been removed is discharged from the discharge pipe 6.

  As another example, when a raw material produced as described above is put into an extrusion molding machine to produce a master batch, the powder rises, so it is necessary to collect dust with a dust collector.

  In the above, since the filter 5 used for the dust collector 4 gradually adheres dust to the outer surface portion, it is necessary to periodically clean it. In order to perform cleaning, it is necessary to remove the filter 5 from the dust collector 4 and perform an operation for removing the adhering dust. When removing dust, care must be taken so that the dust does not rise again. For this purpose, it is necessary to take measures such as wiping the outer surface of the filter 5 with a wet cloth, which is very inefficient. Moreover, many mixing apparatuses 1 as shown in FIG. 5 are arranged in the same factory, and there are many filters 5 to be cleaned. Therefore, the man-hour for cleaning the filter 5 is also great, and improvement is desired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a filter cleaning device that can efficiently clean a cylindrical filter and that is sufficiently environmentally friendly.

In order to solve the above problems, a filter cleaning apparatus according to the present invention is
A device for cleaning the outer surface of a cylindrical filter with one end open and the other end closed,
A housing in which an opening for attaching one end side of the filter is formed at the top;
Provided on the side of the housing and connected to the dust collector suction pipe, and when the filter is mounted on the housing, the outer surface of the filter is sealed, and the filter is opened from one open end. Air is blown to the inner surface of the filter to blow off dust adhering to the outer surface of the filter, and the dust collector can collect the dust.

  The operation and effect of the filter cleaning device having such a configuration will be described. The filter to be cleaned has a cylindrical shape, and has one end opened and the other end closed. When this filter is used in a dust collector, air flows from the outer surface to the inner surface, so that dust adheres to the outer surface of the filter. When cleaning the filter, the filter is inserted from the opening of the housing, and one end of the filter is attached to the opening. The other side of the filter is inserted from the opening and is located in the housing. At this time, the outer surface side (the side to which dust is attached) of the filter is set in a sealed state. Next, air is blown from one end to the inner surface of the filter. That is, air is blown in the backwash direction. Since air escapes from the inner surface of the filter to the outer surface, the dust attached to the outer surface of the filter is blown away. A suction pipe of a dust collector is connected to the side surface of the housing, and the dust blown off is collected by the dust collector. The filter can be efficiently cleaned by using the dust collector for cleaning the filter. Moreover, since the space where dust is blown off is a sealed space in the housing, it is possible to consider the environment. As a result, it is possible to provide a filter cleaning device that can efficiently clean the cylindrical filter and that is also sufficiently considered for the environment.

  In the present invention, the air is preferably blown by an air gun.

  By using an air gun, dust can be blown out vigorously, and filter cleaning can be performed efficiently.

  In the present invention, a disc-like member having an opening is attached to one end side of the filter, and the opening of the housing is set to be larger than the outer diameter of the filter portion of the filter. The outer diameter of the disk-shaped member is preferably set to be larger than the opening of the housing.

  According to this configuration, when the filter is mounted, it is only necessary to insert the other end side of the filter from the opening. A disc-shaped member having an opening formed is attached to one end of the filter, and the outer diameter thereof is larger than that of the opening, so that the disc-shaped member can be mounted on the opening. it can. As a result, the filter can be easily attached and can be easily attached and detached.

  The dust collector according to the present invention is preferably a cyclone type dust collector. Thereby, dust can be collected in a predetermined dust collecting part, and post-processing of collected dust becomes easy.

  A preferred embodiment of a filter cleaning device according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing an outline of a filter cleaning device. FIG. 2 is a perspective view showing an external appearance of the filter cleaning device. FIG. 3 is a diagram showing the shape of the filter. FIG. 4 is a diagram illustrating the setting of the filter.

<Configuration of cleaning device>
FIG. 1 shows a state in which a filter 5 to be cleaned is mounted as a cross-sectional view. The scene in which the filter 5 is used is as already described with reference to FIG. As shown in FIG. 3, the filter 5 has an elongated cylindrical shape, and includes a first end side 5a, a second end side 5b, and a body portion 5c that functions as a filter. A disc-like member 6 is attached to the one end side 5a, and an opening 6a is formed at the center, which is in an open state. The other end side 5b is formed in a closed state. The body part 5c is formed in an accordion shape in which peaks and valleys along the longitudinal direction are formed, and dust is captured on the outer surface thereof.

  The housing 7 has a substantially rectangular parallelepiped shape, and the filter 5 to be cleaned is detachably attached thereto. An opening 7a is formed at the center of the upper surface of the housing 7, and the filter 5 is inserted from the opening 7a. Therefore, the size of the inner diameter of the opening 7 a is larger than the outer diameter of the body portion 5 c of the filter 5. Further, the size of the outer diameter of the disk-shaped member 6 is larger than the size of the opening 7a. Therefore, when the filter 5 is inserted into the opening 7a from the other end side 5b, the peripheral portion of the disk-like member 6 is mounted on the peripheral portion of the opening 7a as shown in FIG. Since the filter 5 can be mounted simply by placing it at the position of the opening 7a from above, it can be easily attached and detached. In the state where the filter 5 is mounted, the space S on the outer surface side of the filter 5 is a space sealed by the housing 7.

  A connecting portion 7 b for connecting the suction pipe 9 of the cyclone dust collector 8 is formed on the side surface of the housing 7. A plurality of rollers 7 d are attached to the bottom of the housing 7 so that the housing 7 can be easily moved. Further, as shown in FIG. 2, a handle 7c is provided on another side surface portion so that the moving operation can be easily performed.

  The cyclone dust collector 8 has a function of sucking dust adhering to the outer surface of the filter 5 through the suction pipe 9. A dust collecting container 10 (corresponding to a dust collecting part) is disposed at the bottom of the cyclone dust collector 8, and dust is collected in the container. The air from which the dust has been removed is discharged from the discharge pipe 11 to an appropriate place. A suction pump 12 is arranged in the middle of the path of the discharge pipe 11 and is operated when the filter 5 is cleaned.

  The air gun 13 blows off dust adhering to the outer surface of the filter 5 by ejecting air from its tip. The operation of the air gun 13 may be performed artificially or automatically.

<Cleaning process>
Next, an operation procedure for cleaning the filter 5 will be described. First, the filter 5 to be cleaned is taken out from the dust collector 4 as shown in FIG. As shown in FIG. 4, the taken-out filter 5 is inserted through the opening 7 a of the housing 7 with the other end 5 b of the filter 5 facing down. The state where the insertion of the filter 5 is completed is shown in FIG.

  Next, the cyclone dust collector 8 is operated to set the dust in a suckable state, and the tip of the air gun 13 is inserted from the opening 7a of the housing 7 to blow out air. Thereby, air is ejected from the inner surface of the filter 5 toward the outer surface, and the dust adhering to the outer surface of the filter 5 is blown away. The dust blown off is sucked by the cyclone dust collector 8 from the space S in the housing 7 through the suction pipe 9 and collected in the dust collecting container 10.

  According to the above configuration, dust is blown off in the sealed space S, and the environment in which the cleaning device is installed is not deteriorated. The air gun 13 is used to blow off the dust, so that the dust can be efficiently removed from the outer surface of the filter 5 and the working time is shortened. Further, since the cyclone dust collector 8 is used, the frequency of maintenance of the filter of the cyclone dust collector 8 itself is less than that of the filter 5 to be cleaned. The greater the number of filters 5 to be cleaned in the factory equipment, the more effective the filter cleaning device according to the present invention. Of course, not only one filter cleaning device but also a plurality of filter cleaning devices may be installed.

<Another embodiment>
The shape of the filter 5 is not limited to the structure described in this embodiment, and various modifications can be considered. The filter 5 may not have an accordion shape, and may be, for example, a normal cylindrical shape.

  Although the powder pigment has been described as an example of dust removed by the filter 5, the present invention is not limited to this, and can be applied to other types of dust.

  When dust is blown off by the air gun 13, an operator may operate the air gun 13, but a configuration in which the air gun 13 is automatically operated may be employed.

  Although the cyclone type thing is used as a dust collector in this embodiment, it is not limited to this.
