本考案は、集塵機の改良に関し、特に、フイル

塵機の改良に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a dust collector, and particularly to an improvement of a dust collector that makes it possible to make the filter area as wide as possible.
円筒型のフイルターを使用する従来の集塵機
は、例えば第５図に例示する様に、機体１の内部

イルターを使用していた。
A conventional dust collector using a cylindrical filter has a cylindrical filter as shown in FIG. Since the structure is such that the filters 5 are installed vertically, the number of filters 5 that can be installed is limited by the planar cross-sectional area of the fuselage 1. That is,
In a dust collector where the size of the body 1 is not limited to, for example, the size shown in Fig. 5, the number of filters 5 to be installed is approximately six at most as shown in Fig. 6, and the total area of the filters 5 is naturally limited. Therefore, if you want to make the filter area even larger (wider),
The length of the filter 5 has been increased, or a molded filter having many pleats formed on the circumferential surface of the filter 5 has been used.
しかし、フイルター５を長くすることは、フイ
ルターの開口面積に比例した風量の増加に共なう
圧損（Pm）が増大する関係で、限度があるし、
一定以上長くすると負圧による圧着を防止するゲ

は一定の制限を受け、従つて、フイルター５を縦
型に取付ける集塵機に於いて、フイルター面積を
上記の限度以上に広くしたい場合には、集塵機自
体を大型化するしか手が無かつた。 However, there is a limit to increasing the length of the filter 5 because the pressure drop (Pm) increases as the air volume increases in proportion to the opening area of the filter.
If the length exceeds a certain level, it is necessary to insert a gauge to prevent crimping due to negative pressure, which leads to the problem of complicating the structure and increasing the price.Also, the method of using a molded filter as the filter 5 is also difficult due to the number of pleats. There is a limit to the height of the filter and the height of the mountain, and there are certain restrictions on increasing the filter area without increasing the number of filters 5. Therefore, in a dust collector in which the filter 5 is installed vertically, the filter If it was desired to increase the area beyond the above limit, the only option was to increase the size of the dust collector itself.
そこで、集塵用機体の内部を、縦仕切板によつ

た。 Therefore, the interior of the dust collection machine is divided into two chambers on the left and right: a dust collection chamber where dust-containing air is sucked in by a vertical partition plate, and a clean room that receives suction action directly or indirectly from a fan. The dust collector itself can be made larger by attaching multiple molded filters, each of which has a pleated surface with a large number of concave and convex concavities, on the side of the partition plate, each facing sideways toward the inside of the dust collection chamber. One idea was to increase the number and area of filters to improve the dust collection ability.

However, in a dust collector with a molded filter mounted horizontally as described above, the dust that falls during the dust removal process accumulates and accumulates in the pleat grooves on the top surface of the molded filter mounted horizontally, reducing the dust collection ability. I had a problem.
従つて本考案の技術的課題は、集塵機の内部に
横向きに取付けた成形フイルターの上面に、除塵

することである。 Therefore, the technical problem of the present invention is to prevent dust that falls during dust removal from accumulating on the upper surface of a shaped filter installed horizontally inside a dust collector.
上記の技術的課題を解訣するために本考案に於

縦仕切板の側面にプリーツ面の角部を上向きに取
付けること。 The interior of the dust collection machine is divided into two chambers on the left and right: a dust collection chamber into which dust-containing air is sucked in by a vertical partition plate, and a clean room which receives suction action directly or indirectly from a fan, and the vertical partition plate In a dust collector in which a plurality of molded filters are installed horizontally toward the inside of the dust collection chamber, each of the molded filters has a filter surface with a large number of concavities and convexities continuous in the longitudinal direction. The shaped filters are formed into a bellows rectangular tube shape with a pleated surface and a rectangular cross section, and each of these molded filters is attached to the side surface of the vertical partition plate with the corner portion of the pleated surface facing upward.
上記の手段は以下の如く作用する。 The above means works as follows.

堆積を防止可能とする。 In other words, each molded filter with the corner of the pleated surface facing upward has pleat grooves that are inclined downward at an angle of about 45 degrees on both left and right sides of the filter with the top as the center. Dust falling onto the upper surface of the filter slides down along the inclined pleat grooves, making it possible to prevent dust from accumulating.
以上の如くであるから、上記の手段によつて上

す。 The molded filter 22 is made of filter paper and has a substantially bellows shape with a rectangular cross section as shown in the figure. By folding, chevron-shaped pleats 22a... are repeatedly and continuously formed in the longitudinal direction.For the vertical partition plate 11, the corners are turned upward as shown in FIG. V-shaped valleys 22b, 22b are provided on both the left and right sides, respectively.
It is installed to form a 45° downward slope.
FIG. 2 shows an example of the mounting arrangement of the molded filters 22, and in the case shown, a total of ten molded filters 22 are mounted. Also, the third
In the figure, 22c indicates a cover plate, and 22d indicates a mounting plate.
尚、前記第５図に示した従来の集塵機の機体１

に増設される関係で、フイルター総面積は10本×
２m2＝20m2と成り、差引き８m2の増加と成る。 Incidentally, the body 1 of the conventional dust collector shown in FIG.
If the fuselage 10 shown in Fig. 1 is made to have the same shape and capacity, and both filters 5 and 22 are made into the same molded filter, and the area of each filter is set to 2 m 2 , the area shown in Fig. 5 is obtained. The conventional dust collector shown in
The total area of the filters is 6 x 2 m 2 = 12 m 2 .
On the other hand, in the dust collector of the present invention in which each filter 22 is installed horizontally, the number of filters 22 is increased to 10, so the total area of the filters is 10 x
2m 2 = 20m 2 , resulting in an increase of 8m 2 .
従つて、第５図の様に通常の円筒型フイルター
５を縦型に取付けた従来の集塵機と本考案の集塵

から外気に排気される。 Since the dust collector according to the present invention has the configuration as described above, the suction force acting on the inside of the clean chamber 13 through the suction duct 19 due to the rotation of the dust collection fan 18 is transmitted to the dust collection chamber 13 through each molded filter 22.
The dust is sucked into the dust collection chamber 12 from the dust suction duct 16 by riding on this suction airflow, and there, the dust is sucked into the dust collection chamber 12 through the dust suction duct 16.
..., and only clean air is sucked from the clean chamber 13 through the suction duct 19, and the exhaust pipe 21
is exhausted to the outside air.

3 is operated to remove dust from each molded filter 22, but the dust DS (see Fig. 4) that falls onto the upper surface of the lower molded filter 22 due to this dust removal operation is removed from each V-shape inclined at 45 degrees. Shape valley part 22b, 2
2b as shown by the arrow, and care is taken to prevent dust DS from accumulating on the upper surface of each molded filter 22.

As described above, according to the dust collector of the present invention in which the filter is installed horizontally, the number of filters installed can be considerably increased compared to the conventional dust collector in which the filter is installed vertically, and furthermore, the number of filters installed can be increased considerably, and furthermore, the number of filters installed can be increased considerably compared to the conventional dust collector in which the filters are installed vertically. By using a molded filter with a pleated surface, the total area of the filter can be greatly increased, and if the entire body of the dust collector is formed vertically and vertically, the installation area (flat cross-sectional area) of the dust collector can be reduced.
It is possible to further increase the filter area by increasing the number of filters installed without increasing the
Therefore, it is possible to demonstrate an excellent dust collection effect despite its small size, but in particular, in this invention,
The dust that falls onto the top surface of each filter during dust removal is guided by the slope and falls downward one by one, which prevents the dust removal dust from accumulating when the molded filter is installed horizontally, making it an excellent choice. It has a great practical value because it has a simple structure and is easy to implement.
