Description

[Detailed description of the invention] The present invention relates to a filter dust removal device, and a dust collector.

The present invention relates to a filter dust removal device suitable for removing dust attached to a filter of a vacuum cleaner or the like.

There have been various types of mechanisms for removing collected dust in filters used in dust collectors, etc., but when the filter material is soft, especially cloth, the surface of the filter itself Various methods have been adopted, including directly hitting the dust, shaking it, scraping off the dust, and blowing it against the wind.

However, all of these devices require space, are complicated mechanisms, and are disadvantageous in terms of cost.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a filter dust removal device that is simple and inexpensive and has a high dust removal effect even in cloth filters.

The main point of the present invention is that in the case of a relatively hard filter material such as non-woven fabric, if vibration is applied to a part of the filter, the vibration will be transmitted to the entire filter surface and the dust removal effect will be large. It is a well-known fact that cloth (woven fabric) is suitable as a filter material in the case of , and in the case of such a cloth filter, the material itself is soft, so even if a part of the filter is subjected to vibration, In order to deal with the fact that the image cannot be transmitted over the entire surface of the filter, it is possible to vibrate the entire surface of the filter using a simple method.

A feature of the present invention is a breathable filter that is suitable for use in dust collectors, etc., and has an excitation plate attached to the inside of a bag filter in a filter section that filters and collects suction dust. This is in a filter dust removal device equipped with a shape retainer.

Next, embodiments according to the present invention will be described based on the respective figures.

Here, Fig. 1 is an overall perspective view of a dust collector for a grinder equipped with a filter dust removal device according to an embodiment of the present invention, and Fig.
The figure is an enlarged sectional view, and Figure 3 is an enlarged cross-sectional view.

FIG. 4 is an exploded perspective view of a filter dust remover according to an embodiment of the present invention, also showing a dust remover, and is an enlarged cross-sectional view of the main parts thereof.

In each of the above figures, 1 is a grinder motor.

2 is the grinder whetstone, 3 is the hood, 4 is the mounting gasket, 5 is the water receiver for the grindstone, 6 is the dust collector body, 7 is the dust removal knob, 8 is the dust removal arm, 9 is the sealing part, 10 is the dust collector body. It's a dust box.

Further, 11 is a dust removal lever, 12 is a dust remover, 13 is a filter, 14 is a filter frame, 15 is a filter shape holder,
16 is a vibration plate, 17°, 18 is a spark prevention plate, 19 is a fan, 2o is a dust collector motor, 21 is a discharge louver, 2
2 is a switch.

That is, first, as shown in FIG. 1, the illustrated dust collector for a grinder has a double-headed grinder mounted on the upper part of the dust collector body 6, and collects grinder powder without using a duct or the like.
The dust collector body 6 directly performs suction filtration.
The entire area is very compactly guarded.

This will be explained in more detail with reference to FIG. 2. By operating the switch 22 shown in FIG. 1, the grinder motor 1 and the dust collector motor 20 are operated to generate a flow of air in the flow path indicated by the solid arrow.

Then, the dust ground by the grinder whetstone 2 is
The air is sucked through the hood 3, passes through spark prevention plates 17 and 18, and is filtered by the filter 13, so that only clean air is produced.
The dust is guided from a fan 19 directly connected to the dust collector motor to a discharge looper 21 as indicated by the dashed arrow, and is discharged outside the machine.

In the above, the grinding dust collected on the filter 13 is removed by reciprocating the dust removal knob 7 shown in FIG. A removing element 12 provided on the dust removing lever 11 is moved linearly to vibrate the filter 13, which is then brushed off and stored in the dust box 1o.

This dust removing structure for dust removal will be described in detail below with reference to FIG. 3.4.

That is, as shown in FIG. 3-4, the filter section and the dust removal section include a filter section in which a filter 13 related to a corrugated cloth filter, that is, a bag filter, is fixed to a filter frame 14, and the filter 13. A soft K material with breathability similar to woven fabric is placed on the P side of the filter to prevent the filter 130 from being crushed by suction wind pressure.
Filter shape holder made of M material 15. This filter shape holder 15 is composed of a vibrating plate 16 (a thin plate-like member with a thickness of about 1 mm) having elasticity such as a plastic group made of plastic. 16 is U-shaped, and both ends thereof are filter shape holders 15.
This protruding part protrudes from the side of the dust remover 12 (
It is designed to apply vibrations by bending and restoring a thin metal or plastic plate (such as a thin metal or plastic plate or a spring).

Therefore, when the dust remover arm 8 is moved as shown by the arrow in FIG. 4, the dust remover 12 and the vibrating plate 16 come into contact and both are bent as shown. When the dust removing arm 8 is further moved, the vibrating plate 16 is repelled by its elasticity, and the vibration is transmitted to the entire filter shape holder 15, and the filter 13
The entire surface of the machine vibrates, causing the attached dust to peel off and fall.

According to the above-described aspect, vibrations are sufficiently transmitted to the entire filter surface, so that the dust removal effect is extremely large.

According to the experimental results, as shown in the dust removal performance comparison diagram in Figure 5, compared to the conventional tapping method shown by the broken line, the method according to the present example shown by the solid line has better dust removal performance and original φ state. It has been revealed that the relationship between the amount of collected dust and the amount of suction air is significantly improved, including the point that the filter returns to
However, it has also been confirmed through experiments that the size increases.

And, while it is effective in this way, its structure maintains the filter part and filter shape.

It has a simple configuration with parts related to vibration, and along with this,
Since it can be sufficiently miniaturized and the space it occupies can be significantly reduced, this also leads to the miniaturization of dust collectors and the improvement of productivity.

However, the above lol M? In the case of IJ, the shape of the vibrating plate is in the shape of an opening, but it can be in the shape of an opening or any other shape as long as it is capable of imparting the vibration of the dust removal reservoir.

Moreover, although the above-mentioned one relates to a dust collector for a grinder, the present invention is a general-purpose one that can be applied to other dust collectors or dust collectors such as vacuum cleaners.

Taking all of the above into account, the present invention makes it possible to remove dust from cloth filters, which has been considered difficult in the past, with a very simple operation and a great effect. At the same time, the large space occupied by conventional dust removal mechanisms can be made smaller and more compact, making it an effective tool that can greatly contribute to the high performance and miniaturization of devices that use filters, such as dust collectors. This is an excellent invention.
