Description

  The present invention relates to a screen panel connecting device in a screen type dust remover, and in particular, in a panel type screen dust remover, the gap between the screen panels is eliminated to prevent the outflow of residue and the bending performance between the screen panels is maintained. In addition, the present invention relates to a screen panel connecting device in a scree-type dust remover that eliminates bending defects due to clogging.

2. Description of the Related Art Conventionally, in a small-scale sewage treatment plant, agricultural water, and other pumping stations, a screen type dust remover that is attached to a sewage or a water intake to prevent inflow of residue (garbage) has been proposed.
This screen type dust remover has a plurality of screen panels connected endlessly (in an endless shape) and connected in a caterpillar shape, which is installed in a water channel to pass running water while catching debris from the water intake. The residue trapped by the rotational drive is scraped up from the water and removed out of the water channel.
An endless screen is formed by connecting a large number of screen panels in a caterpillar shape. Each screen panel has a large number of metal plates arranged in parallel in the thickness direction at predetermined intervals, and the screen mesh. In order to secure the width, a gap holding member is sandwiched between a number of metal plates and formed in a comb-like shape, which is adjacently arranged in an endless manner, and can be bent and stretched between connecting screen panels at adjacent positions. It is configured to be assembled.

  By the way, in the screen type dust remover using the conventional panel described above, the screen panel assembled by sandwiching the spacing member between a large number of metal plates is connected to each other by overlapping the flange portions of the adjacent screen panels. A connecting pin is inserted through the overlapping portion of both flanges so that the screen panels are bent within a predetermined angle range.

  For this reason, when connecting the screen panels of this screen type dust remover, a predetermined portion between the screen panels is connected to the connecting portion by the connecting pins of the adjacent screen panels so that the adjacent screen panels can be bent within a predetermined angle range. Since a gap is formed between adjacent screen panels, the residue from the gap flows in with the water intake, and the residue is easily clogged in the gap, so that the flexibility between the adjacent screen panels is increased. If the gap between the screen panel joints is made as small as possible so as to reduce the passage of residue from this gap, the screen will be bent and stretched. There is a problem that the panel joints slide against each other and wear occurs, shortening the service life.

  In view of the problems of the screen type dust remover using the above-described conventional panel, the present invention prevents a gap from being generated in the screen panel joint, and the screen panel can be bent smoothly by expansion and contraction of the connecting member. An object of the present invention is to provide a screen panel connecting device in a screen type dust remover that can be made.

  In order to achieve the above object, the screen panel connecting device in the screen type dust remover of the present invention is such that an elastic connecting member is interposed in a connecting connection portion by a connecting pin between adjacent screen panels arranged endlessly. It is characterized by comprising.

  In this case, the screen panel is formed by pressing a plurality of metal plates to form a plurality of protrusions or protrusions having substantially the same height, and the metal plates are superposed through the protrusions or protrusions, The polymerized metal plate can be fixed and integrated by a frame body.

According to the screen panel connecting device in the screen type dust remover of the present invention, the connecting member made of the elastic body is interposed in the connecting portion by the connecting pin between the adjacent screen panels arranged endlessly. Therefore, since the elastic connecting member is expanded and contracted, it is possible to eliminate the gaps and sliding between the screen panel connecting joints and prevent the inflow and pinching of the residue.
Further, the configuration and assembly of the screen panel can be simplified and manufactured at low cost.

  In addition, a plurality of ridges or projections having substantially the same height are formed by press molding on a number of metal plates, and each metal plate is polymerized through the ridges or projections, and the polymerized metal plates are framed. By constructing the screen panel by fixing and integrating with the body, it is possible to easily manufacture by simply overlapping the metal plates and fixing them with the frame body. As in the past, the metal plates and the spacing members are alternately bolted. In addition, it is not necessary to assemble it through, and no spacing member is required, so that it can be manufactured at low cost, and the protrusions or protrusions are formed by press molding, so it can be easily formed on a large number of metal plates. The screen width of the screen can be easily changed by changing the height of the ridges or projections.

  Embodiments of a screen panel connecting device in a screen type dust remover according to the present invention will be described below with reference to the drawings.

1 to 2 show an embodiment of a screen panel connecting device in a screen type dust remover of the present invention.
In this screen type dust remover, the screen panel connecting device has a plurality of screen panels P, P arranged in an endless manner, and a connecting pin 4 is arranged between the adjacent screen panels P, P to connect them. An elastic coupling member 5 is interposed along the coupling pin 4 of the coupling connection portion.

  The screen panel P is not particularly limited. For example, a plurality of metal plates 1 are superposed in a comb-like shape with a predetermined gap therebetween, and are fixed and integrated by a frame 3. The screen panel P is configured, and the punching metal 6 having a required size is fixed by the frame 3 and integrated to form the screen panel P. The punching metal, slit plate, resin honeycomb plate, bar screen It can comprise with arbitrary materials, such as.

When the screen plate P is configured by arranging the metal plates 1 in a comb-teeth shape, a plurality of ridges 2 having substantially the same height are formed on a large number of metal plates 1 by press molding, and the ridges 2 are interposed through the ridges 2. Each metal plate 1 is superposed, and the superposed metal plate 1 is fixed and integrated by a frame 3 to form a screen panel P1 as shown in the right half of FIG.
The ridges 2 have substantially the same height in the same metal plate 1, but can be different in different metal plates 1, and the ridge 2 is not particularly limited. As shown in FIG. 2 (A), a plurality of convex strips 2 having a V-shaped cross section can be press-formed on one side so that the positions of adjacent metal plates 1 are different.
Further, as shown in FIG. 2 (B), the ridges 2 in the metal plate 1 can be formed into a plurality of oval ridges 2, which are press-formed on one side at both ends of the metal plate 1. As shown in the left half of FIG. 3, a screen panel P <b> 2 can be obtained.
And the predetermined space | gap used as the mesh width of a screen is ensured between the metal plates 1 by superposing | polymerizing the metal plate 1 with each protrusion 2 or the convex part 2 facing the same side.
Since the screen panels P1 and P2 are used in an endless manner as a screen of a dust remover, a metal plate 1a with a hook for scraping off the residue is partially disposed. There is also.
The frame 3 includes an outer frame 31 having a U-shaped cross-section that is fitted to a side portion of the polymerized metal plate 1, and end plates 32 that are fixed to both ends of the outer frame 31. At both ends, flange portions 34 projecting outward are formed. The flange portion 34 is aligned with the end plate 32, and a connecting hole 33 is formed in the overlapping portion, and a connecting pin is passed through the hole. By doing so, it connects between the frame bodies 3 and 3 of the adjacent screen panel P so that bending is possible.
If the metal plate 1 is inserted inside the outer frame 31 as a guide as shown in FIG. 2A, the screen panel can be assembled easily.

The screen panel P configured as described above forms a plurality of substantially the same height of protrusions 2 or protrusions 2 on a large number of metal plates 1 by press molding, and each of the protrusions 2 or protrusions 2 through the protrusions 2 or protrusions 2. Since the metal plate 1 is polymerized and the polymerized metal plate 1 is fixed and integrated by the frame 3, it can be easily manufactured simply by stacking and fixing the metal plate 1 by the frame 3. Thus, it is not necessary to assemble the metal plate and the spacing member alternately by passing through the bolts, and further, the spacing member is not necessary and can be manufactured at low cost.
And since the protrusion 2 or the convex part 2 is by press molding, it can be easily formed also with respect to many metal plates 1, and it is easy by changing the height of this convex part or convex part. The screen width can be changed.

Further, when the screen panel P is configured using a punching metal, the punching metal 6 cut to a required size is not particularly limited as shown in the right end of FIG. Both ends are bent into a square shape, and this is integrated with the outer frame 31 of the frame 3 by welding or screwing.
Furthermore, instead of the punching metal, a slit plate, a resin honeycomb plate, a bar screen, or the like can be employed.

As shown in FIGS. 1 and 3, in order to connect the screen panel P thus configured in an endless manner, the connection holes 33 and 33 formed in the end plate 32 of each screen panel P are matched. In such a manner, the bar-like or bolt-like connecting pin 4 is inserted into the connecting holes 33, 33. In this case, the link plate 7 of the link chain is provided outside the end plate 32 and is connected together by the connecting pin 4, and made of an elastic material along the connecting connection portion between the screen panels P, P. A connecting member 5 that is easily deformed and restored by a material such as synthetic rubber or synthetic resin is interposed.
The connecting member 5 is inserted into a gap formed so that the adjacent screen panels P, P can be easily bent, and the shape thereof is not particularly limited. For example, the screen panel P, A hollow rectangular bar shape that can be inserted into the gap between P is formed, and the connecting pin 4 is inserted into the hollow square bar-shaped connecting member 5. As a result, the gap between the screen panels P and P to be connected can be eliminated, so that there is no sliding between the screen panels, and the bending between the screen panels P and P is caused by the expansion and contraction of the connecting member 5 when bending. Therefore, it is possible to easily prevent the passage of residue and the like and to eliminate clogging of the residue.

  As mentioned above, although the screen panel coupling device of the screen type dust remover of the present invention has been described based on the embodiments, the present invention is not limited to the configuration described in the above embodiments, and does not depart from the spirit thereof. The configuration can be changed as appropriate.
