本発明は周囲に多数の軸方向裏を形成してなる漣過筒に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter cylinder having a plurality of axial backs formed around its periphery.
従来この種凝過筒としては第６図及び第７図に示すよう
な形状が一般的であった。Conventionally, this type of condenser tube has generally had a shape as shown in FIGS. 6 and 7.

能率が悪くコスト高なゾル成型に代わる方法としてまず
思い浮ぶのは合成樹脂の射出成型で両端板を一挙に成型
することである。That is, a strip of paper or nonwoven fabric with a large number of folds folded at a uniform depth is bent into a cylindrical shape and both ends are joined to form a tube opening with a so-called chrysanthemum-shaped cross section. One end of the cylinder mouth is closed with an end plate C, and a flange-shaped end plate 2 is fixed to the other end in consideration of shape retention and installation convenience. The material of the tube mouth, which is sarugami or non-woven fabric, is usually treated with resin to give it hardness. End plates C and 2 are formed by sol molding of vinyl chloride. Sol molding will be explained based on FIGS. 8 and 9. First, a mold having a cavity wood into which the end of the tube mouth is inserted is prepared, and the cavity wood is filled with vinyl chloride solt. Solt is made by adding a vulcanizing agent, a vulcanization accelerator, a stabilizer, etc. to chlorinated vinyl resin to make it fluid. The end of the tube mouth shown in Fig. 9 is placed in this solt, and placed in a drying oven at 180° C. to 190 qo for 7 to 8 minutes to dry, thereby completing one end plate. Next, the tube mouth is turned upside down and the other end is placed in another mold filled with PVC sol, and the other end is placed in a drying oven as before to complete the other end plate.
Because of this process, it takes about 30 minutes per piece to mold the end plates. If you want to perform continuous work, it is necessary to prepare a large number of molds and run them through the process one by one, but this requires a large area to arrange the molds, and a machine to inject the sol into the molds. Not only that, but a drying oven was also required, and as a result, manufacturing holster tubes by sol molding required a large amount of capital investment. Now, the first thing that comes to mind as an alternative to the inefficient and costly sol molding is to mold both end plates at once using synthetic resin injection molding.

とになる。本発明は上記諸種の問題を解決せんとしてな
されたもので、新規な猿過筒形状を創造し、工業的生産
性を向上させたものである。With injection molding, the molding time is expected to be about 1.5 minutes, and equipment costs are low. Its simplest form is shown in FIG. In this method, one core mold is prepared in the same way as one cavity mold, a cylinder mouth is sandwiched between the two molds, and molten resin is injected into the cavities provided in the shape of both end plates. It is. However, with this method, as shown in Figure I1, when the tube mouth is inserted into the cavity mold hole and the molds are matched, the core cross section is complex and the tube mouth itself does not maintain a geometrically accurate cross-sectional shape. The corner of the core mold inevitably got caught on the end of the tube mouth, and damage to the tube mouth could not be avoided. To solve this problem, as shown in Figure 12, the cavity mold can be divided into many parts, and the tube mouth covered with the core mold can be attached vertically from the outside, but it is suitable for the tube mouth with a chrysanthemum-shaped cross section. In order to do this, a large number of split molds are required, and as the number of hairs increases, the number of molds increases, and the inherent advantages of injection molding in terms of mold production costs and production control are greatly diminished. become. The present invention was made to solve the various problems mentioned above, and it creates a new shape of the sieve tube and improves industrial productivity.
以下図面に塞いて説明する。This will be explained below with reference to the drawings.

補強層１０を設けている。The cross-section tube 1 of the present invention shown in FIG. 1 is characterized by its cross-sectional shape. That is, it is the same as the conventional method in that a large number of strips are folded at a uniform depth into a strip of moat material, the strip is cut to an appropriate length, and both ends are joined to create a loop. 2
are grouped into several groups for each predetermined angle section. It is best to limit the number of angle divisions to 1 and not to increase them too much. In the illustrated embodiment, it is six.
The groups therefore range from GI to G6. The number of hairs in each group is 6. The hairs, which are the constituent molecules of each group, all protrude in the same direction. In other words, when you draw lines that bisect the apex angle of each rhombus, those lines are parallel for each group. The cylinder 3 bent in this way has its rear ridge lines lined up on the same plane for each group, making it look like a hexagonal prism.
This tube 3 is then sandwiched between a platen mold 4, a cavity mold 5, and a core mold 6 as shown in FIG. 3, and molten resin is injected into the cavity to form end plates 7 and 8. . In this case, the number of divisions of the cavity mold 5 only needs to be the same as the number of hair groups. In other words, in the case of the embodiment, it is sufficient to divide it into six pieces. As described above, according to the present invention, in order to manufacture a needle tube having the same number of shapes, injection molding can be performed using a significantly smaller number of molds than in the case of a needle tube with a conventional shape. The small number of molds means that the structure of the molding machine is simple, and the number of mating surfaces is small, making mold production easier, which is advantageous in terms of both mold production cost and molding cost. That is beyond debate. Note that even though the protruding directions of the hair are made to be the same, it is not necessary to make them exactly match, and some error is acceptable. The sieve tube 1 of the embodiment is for gas permeation, and we will consider the case where a rotary repellent body 9 (shown by a phantom line in FIG. 2) is arranged inside to brush off dust adhering to the outer surface. A reinforcing layer 10 of resin is provided at the inner end of the hair.

要がある。第５図のように菱の内側に除塵用振動板１４

く方法も有効である。This can be easily formed by providing the end plate cavities 11 and 12 as well as the reinforcing layer cavity 13 in the mold. In this case, it is preferable to change the height of the reinforcing layer 10 so that the inner end envelope of the hair forms a circle as shown in the figure. This is so that the rotating repellent body 9 can evenly repel all hair. In particular, even if a reinforcing layer is not provided, it is preferable that the inner end envelope of the back side is a circle in consideration of the combination with the rotary repellent body. However, in this case, it is necessary to change the folding depth on the back. As shown in Figure 5, there is a diaphragm 14 for dust removal inside the rhombus.
It is also effective to insert the diaphragm 14 and flick the end of the diaphragm 14 with the rotating repellent body 9.
この時も振動板１４の内端包絡線を円にしておくと良い
。また実施例では髪群の境界毎に端板７，８を連結する
補強片１５を設けている。At this time as well, it is preferable to make the inner end envelope of the diaphragm 14 a circle. Further, in the embodiment, a reinforcing piece 15 for connecting the end plates 7 and 8 is provided at each boundary between hair groups.
これも金型にキャビティ１６を設けておくだけで簡単に

すぐれた漣過筒を安価に提供出来る。This can also be easily formed by simply providing the cavity 16 in the mold. As described above, according to the present invention, a large number of axial backs are formed around the periphery, the backs are divided into a plurality of groups according to predetermined angle divisions, and these diamonds are made to protrude in the same direction for each group, and Since a reinforcing layer such as resin is formed on the inner end of each hair so that the envelope line is approximately circular, it is not only easy to mold with a mold, but also has a strong shape when combined with a rotary repellent body. It is possible to provide a scraping cylinder which is uniformly repelled and has excellent acid removal performance and strength at a low cost.
