Abstract

PURPOSE:To suppress abrasion of a filter and to secure vibration of the filter sufficiently by constituting a dust removing piece with low abrasion resistant material and fitting it to a coil spring made of metal. CONSTITUTION:Dust filtered and collected on a filter 26 is detached with a dust removing apparatus 35. A lug 7 is projected to the outside of a case and moved reciprocally. The lug 7 is connected with a bearer 27 for a dust removing piece via the first lever and the second lever. The dust removing piece 25 is fitted by screwing a screw 32 into a female tread 34 via a small diameter part 30 of the dust removing piece spring 24 and the spring 24 is fitted to the bearer 27 with a screw 33 via the other small diameter part 31. Therefore, by moving the lug 7 reciprocally, the dust removing piece 25 is turned and the top part of the filter 26 is flipped with the piece 25 and the attached and collected dust 29 can be detached therefrom.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a filtration type dust collector having a dust removal device.

[Background of the invention]

In filtration type dust collectors, the pressure loss increases due to dust adhering to the filter, and the amount of dust suction decreases. Therefore, a dust collector such as a metal spring is brought into contact with the filter, and the filter is flicked and vibrated. Also, dust attached to the filter is removed. However, in such a dust remover, since the dust remover made of a metal spring is brought into direct contact with the filter surface, the filter wears out in a short time due to the frictional contact of the dust remover or the *S impact force.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a filtration type 111M machine that can prevent the filter from being worn out without reducing the dust removal effect of removing dust adhering to the filter.

[Summary of the invention]

The present invention has a filter 26 formed of a nonwoven fabric in a wave shape,
In a filtration type dust collector equipped with a dust remover 35 that vibrates to flick the top of the filter 26, the dust remover 35 is composed of at least a dust remover spring 24 and a dust remover 25 attached to one side thereof. A p-type dust collector, characterized in that the dust remover spring 24 is a metal coil spring, the dust remover 25 is made of a material with lower wear resistance than the filter 26, and its tip is approximately spherical.

According to the present invention, since the dust remover 25 that vibrates the filter 26 is made of a material with lower wear resistance than the filter 26, even if the dust remover 25 comes into contact with the surface of the filter 26, the dust remover 25 is worn out, and the filter 26 can be minimized, and since the dust remover 25 is attached to the dust remover spring 24 made of a metal coil spring,
It is possible to provide a p-type dust collector that can ensure a large amount of vibration given to the filter 26.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS.

7 amps inside the outer case 1 10. It has a built-in filter 26, etc. A fan 10 is directly connected to a motor 11 by turning on a switch 8 attached to the side of the case 1.
rotates, creating negative pressure inside the cage 1. Due to negative pressure,
Dust from the source is sucked together with air through the hood, duct, etc. connected to the suction port 2 on the side of the case 1, the dust is collected by the filter 26, and clean air reaches the fan 10. The air is discharged through the fan outlet 12 and then to the outlet 9 on the top surface of the case 1.

The dust collected by the filter 26 is removed by the operation of the dust removing device 35. ．． 6, falls and is stored in the dust box 3. The dust stored in the dust box 3 can be taken out and disposed of by removing the clamp 4 and pulling the dust box 3 forward.

The dust removal device 35 for removing dust filtered and collected by the filter 26 will be explained. Knob 7 on the outside of case 1
is made to protrude, and this knob 7 is made to reciprocate as shown by the arrow in Fig. 3.

The knob 7 is connected to a second lever 20, and the second lever 20 is connected to one end of a second lever 22 that rotates around a fulcrum 30. A dust remover support 27 is directly connected to the second lever 22, and the dust remover support 27 has a dust remover spring 24 and a plastic dust remover 25 at the tip of the spring 24. The positional relationship between the dust remover spring 24, the dust remover 25, and the filter 26 is as shown in FIG.
A head remover is placed on the top of the filter 26 so that only the dust remover 25 comes into contact with the top of the filter 26 by a distance of 9G. Further, the diameter of the dust remover 25 is made smaller than the pitch Pj of the filter 26.

Details of the dust remover 25 and the dust remover spring 24 are shown in FIG.

It is shown in FIG. The dust remover 25 is the small diameter portion 3 of the dust remover spring 24.
The spring 24 is attached to the dust remover support 27 by screwing the screw 32 into the female thread 34 through the other small diameter portion 31 with the screw 33. Therefore, by reciprocating the knob 7, the dust remover 25 is rotated via the first lever 20, the second lever 22, etc.
The top of the filter 26 is flicked off to vibrate the filter 26, and the attached dust 28 can be removed.

The dust remover spring 24 is made of a metal coil spring, and the dust remover 25 is made of a filter 26 made of polyester nonwoven fabric and is made of abrasion-resistant low H6 nylon.

Furthermore, since the shape of the dust remover 25 has a spherical tip, there is no directionality with respect to the filter 26, and even circular movement as shown by the arrow in FIG. 5 of this embodiment has a good dust removal effect. There is no change in lifespan etc.

According to this embodiment, the dust remover 25 that vibrates the polyester nonwoven fabric filter 26 is made of nylon 6, which has lower abrasion resistance than the filter 26, so that even if the dust remover 25 comes into contact with the filter 26, It is extremely rare for the dust remover 25 to wear out and the filter 26 to wear out. Thereby, the life of the filter 26 can be extended.

On the other hand, although the dust remover 25 wears out, the filter 2
The spring should be sized so that it has a longer lifespan than 24.
Since it is attached to the filter 26, it is possible to ensure a large amount of vibration given to the filter 26.

〔Effect of the invention〕

According to the present invention, since the dust remover 25 that vibrates the filter 26 is made of a material with lower abrasion resistance than the filter 26, even if the dust remover 25 comes into contact with the surface of the filter 26, the dust remover 25 is worn out. Abrasion of the filter 26 can be minimized, and since the dust remover 25 is attached to the dust remover spring 24 made of a metal coil spring,
It is possible to provide a filtration type dust collector that can ensure a large amount of vibration given to the filter 26.
