Abstract

PURPOSE:To provide the titled filtering type dust collector made stable in a sucking air amount through the enhancement of dust removing effect, in suction type dust collection by a V-shaped multi-pleat unwoven fabric, by striking and vibrating the surface of filter cloth by the elastic dust removing element of an arm swung by a link mechanism. CONSTITUTION:Air sucked by rotating a turbo fan 3 enters a machine and passes the filtering surface of a V-shaped multi-pleat unwoven fabric 17 to be exhausted from an emitting port 5. An elastic dust removing element 10 such as a spring is provided to a dust removing arm 11 awung around a fulcrum point 15 by the cam 14 and the arm 12 of a motor 13 and a large number of pleats of the filter cloth 17 are flipped and vibrated to shake off dust adhered to the filtering surface. By this method, dust removing effect becomes good and a sucked air amount is made stable simply.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an industrial dust collector that suctions and collects dust in order to protect the health of dust workers, and particularly relates to means for improving its suction performance. .

[Background of the invention]

The dust removal devices of conventional dust collectors can be broadly classified as follows: 1) A method in which the filter is vibrated to remove adhering dust by directly moving the filter by operating a control lever or the like.

2) There are methods to remove adhering dust using air force, such as backwashing.

The former can be manufactured at low cost, but the dust attached to each filter element 2 is shown in Fig. 1 (side cross-sectional view of a filter-type dust collector equipped with a conventional dust removal device) and Fig. 2 (detailed view of a part of the filter). By moving the operating lever 8 in the direction shown by the arrow, the dust remover 7 provided on the operating lever 8 is moved, and the filter element 2 is swung to remove dust. However, with the method described above, there is a problem in that the dust removal effect varies greatly depending on the speed of the reciprocating motion of the operation lever.Furthermore, since the lower part of the filter element 2 is in a free state, the filter elements 2 may be pecking together due to wind pressure. There was also the problem that the tear material surface of the filter could not be used effectively, leading to early clogging.

In addition, even if a lot of dust adheres to the surface of the filter 9 and the suction air volume decreases, there is also the problem that the user forgets to remove the dust and the dust collector is not used effectively. Ta.

The latter is discharged by a dust collector:! The one using a-1ffl has a weak pressure and is not very effective in removing dust. In addition, compressed air, etc.
There is also a method that utilizes a high-pressure inverse hole using a separate device; 4, but this makes the construction complicated and is disadvantageous in terms of cost.

[Purpose of Okiri]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims to improve the dust removal method and provide an efficient p-filter collection and dust machine.

[Summary of the invention]

The present invention is a simple and efficient method for removing dust attached to a filter by using an elastic body to repel and vibrate the entire surface of the filter, thereby improving the dust removal effect and creating a stable filtration type dust collector with a stable suction scene. It is something to do.

[Embodiments of the invention]

Below, one embodiment of the present invention will be explained with reference to Fig. 3.
The figure shows a side cross-sectional view of an uninvented filtration type dust collector, which consists of a suction port 1 for suctioning dust, a nonwoven fabric filter 17 continuously woven in a V-shape to collect fine dust, and a nonwoven fabric filter 17 for removing dust. The gear mode 13 is the driving part, the dust removal arm (B) 12 converts the rotational motion of the gear mode 13 into linear reciprocating motion, and the dust removal arm (B) 11
, an elastic dust remover 10 for repelling dust in order to restore the suction air volume when the non-woven filter 17 becomes clogged and the suction air volume decreases; a turbo fan 3 for generating suction force; It consists of a moder 4 directly connected to a turbo fan 3, and a discharge port 5 for exhausting clean air, and the air sucked from the suction 1 by the turbo fan 3 flows along the path shown by the dotted arrow.

Fig. 4 shows a detailed diagram of the automatic dust removal device installed in the filtration type dust collector, which removes the rotational movement of the gear mode 13 via the cam 14, converts the dust arm (A) 12 into linear reciprocating movement, and further removes dust. The linear reciprocating motion of the arm (A) 12 is changed to semi-circular fast cutting of the dust removal arm (A) 11 through the fulcrum 15, and the elastic dust remover 10 is installed at any position on the dust removal arm (B) 11. Non-woven molded filter 17
It removes dust by repelling and vibrating the surface.

The advantages of the genital area method of the present invention are that automatic dust removal is possible with a small number of parts and that it can be manufactured at low cost. In addition, this method has the great advantage of being able to fully utilize the suction performance of the filtration type dust collector and use it effectively, since it can prevent variations in the dust removal effect and forgetting to remove dust as described in the prior art. .

[4th Effect] According to the present invention, the effects shown in the following are actually obtained.

(1) As shown in FIG. 5, the dust removal effect is stable and a stable suction air volume can be obtained, so the filtration type dust collector can be used efficiently.

(2) The cost is low because the automatic dust removal device can be manufactured with a small number of parts.

(3) For users, the filter is maintenance-free, making it an easy-to-use product.

(4) Dust removal of young fruit can be greatly improved compared to the conventional technology.
