Abstract

PURPOSE:To stabilize dust collection efficiency by almost perfectly removing the dust in a filter by mounting a dust collecting filter in a case main body and providing a rotary shaft equipped with an air jet nozzle in the case main body in a freely rotatable and up-and-down movable manner. CONSTITUTION:A dust collecting filter 5 is set to the interior of a case main body 3 by the setting member 7 provided to the upper part of the case main body 3. A rotary shaft 11 equipped with an air jet nozzle 15 is provided in the case main body 3 in a freely rotatable and up-and-down movable manner. As a result, the dust in the filter is almost perfectly removed and the filter from which dust is removed is reused in a dust collector to make it possible not only to stabilize dust collection efficiency but also to extend the life of the filter.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is intended for use when a filter of a dust collector installed in a thermal cutting machine that performs thermal cutting on a workpiece becomes clogged with dust, etc. This invention relates to a dust collection filter cleaning machine that cleans filters.

(Prior Art) Conventionally, filters of dust collectors installed in thermal cutting machines, for example, are either replaced when they become clogged or cleaned and reused.

Moreover, as methods for cleaning and reusing the material, there are known a brushing method and a pulse jet method using air. The cylindrical filter used a pulse jet method to remove dust.

(Problems to be Solved by the Invention) By the way, with the above-mentioned conventional dusting method and short-time ejection pulse jet method, it is not possible to completely remove the dust that has entered the filter, and it is difficult to extend the life of the filter. Can not.

Further, when blowing out air, exhaust pressure is applied, so dust may flow back from the dust collecting section, making it impossible to completely remove dust.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to provide a dust collection filter cleaning machine that almost completely removes the dust inside the filter, stabilizes the dust collection efficiency, and extends the life of the filter. be.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a setting member for setting a dust collection filter inside the case body at the upper part of the case body, and blows out air. A dust collection filter cleaning machine was constructed by providing a rotary shaft equipped with a nozzle for rotating and vertically movable inside the case body.

(Function) By adopting the dust collection filter cleaning machine of this invention, when the filter used in the dust collection device becomes clogged, the filter can be removed from the dust collection device and set on the top of the case body of the cleaning machine. do. Next, by rotating the rotating shaft and moving it up and down, air is ejected from the nozzle provided on the rotating shaft toward the filter.
Dust attached to the filter is almost completely removed.

The filter that removes this dust is then reused in the dust collector, stabilizing the dust collection efficiency and extending the life of the filter.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Referring to FIG. 1, a case body 3 of a cleaning machine 1 is formed of a hollow cylindrical container with an open top. The upper surface of the case body 3 is covered from above with a lid 7 as a set member to which a cylindrical filter 5 that has become clogged after being used in a dust collector is removably attached.

A cylinder device 9 for rotation and vertical movement is provided on the lower wall 3D of the case body 3.

A hollow rotating shaft 11 extending in the vertical direction is provided in the upper center of the cylinder device 9.
A swivel joint 13 is provided in the middle of 1. A nozzle 1 for ejecting air is provided on the upper part of the rotating shaft 11.
5 is provided.

One end of an air hose 21.23 is connected via a connecting plug 17.19 to the upper and lower outer circumferential portion (right side in FIG. 1) of the cylinder device 9, and the air hose 2
The other end of 1.23 is pulled out from a hole formed in the lower part of the right side wall of the case body 3 and connected to an air source (not shown). In addition, the swivel joint 13
to the flexible air host 2 via the connection plug 25.
One end of the air hose 27 is connected to the air hose 27, and the other end of the air hose 27 is pulled out from a hole formed in the lower part of the right side wall of the case body 3 and connected to an air source (not shown).

The cylinder device 9 is connected to, for example, an air hose 21 from an air source (not shown). It has a rotation mechanism that rotates the rotation shaft 11 by supplying air through the connection plug 17, and also has a vertical movement mechanism that moves the rotation shaft 11 up and down. In addition, since the rotation mechanism and the vertical movement mechanism are known ones, a detailed explanation thereof will be omitted.

For example, an open hole 29 is formed in the upper right wall of the case body 3, and one end of a connecting pipe 31 is connected to the hole 29, and a blower (not shown) is connected to the other end of the connecting pipe 31. Device is connected. A filter 33 is provided in the middle of this connecting pipe 31.

A support block 35 for supporting and guiding the rotary shaft 11 is provided at approximately the center of the case body 3 so that the rotary shaft 11 rotates and moves up and down. One end of a plate-shaped inclined plate 37 is attached. Further, a dust box 39 is attached to the inner wall of the case body 3.

The other end of the inclined plate 37 is supported by a side wall of the dust box 39.

With the above configuration, the filter 5 that has been used in the dust collector and has become clogged is first removed from the dust collector and attached to the back side of the lid 7 as a set member, and this lid 7 is attached to the case body 3.
Place it over the top of the

Next, a switch such as a push button is turned on to operate a blower (not shown) and the cylinder device 9.

When this cylinder device 9 operates, the rotating shaft 11 rotates and moves up and down, and an air hose 27,
Air is blown out through the connection plug 25, swivel joint 13, and rotating shaft 11.

The air ejected from the nozzle 15 blows off the dust attached to the filter 5 and removes it from the dust box 3.
At the same time, it is adsorbed by the filter 33. Note that since the nozzle 15 is provided at the tip of the rotating shaft 11, it rotates and moves up and down, so that the dust adhering to the inner peripheral surface of the cylindrical filter 5 can be almost uniformly removed.

In addition, since this cleaning machine 1 can operate continuously for a fixed period of time using a timer, rather than cleaning in a short time like the pulse jet method built into a dust collector, it can be used to prevent clogging of the filter 5. can be kept to a minimum and stable dust collection efficiency can be maintained for a long period of time. Furthermore, unlike air blowing, it does not need to be done manually, so it does not pollute the environment.

This invention is not limited to the embodiments described above, but can be implemented in other forms by making appropriate changes.

[Effects of the Invention] As can be understood from the above description of the embodiments, according to the present invention, when the filter used in the dust collector becomes clogged, the filter can be removed from the dust collector and cleaned. Place it on the top of the case body of the machine. Then,
By rotating and moving the rotating shaft up and down, air is ejected from a nozzle provided on the rotating shaft toward the filter, making it possible to almost completely remove dust attached to the filter.

The filter from which this dust has been removed is reused in the dust collector, thereby stabilizing the dust collection efficiency and extending the life of the filter.
