Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a hook for a settling slope plate for hooking and fixing a settling slope plate used for solid-liquid separation by a sedimentation method on its support rod. .

(Prior Art) As illustrated in FIG. 7, for example, in a sedimentation tank A of a water purification plant, a frame B is installed in the sedimentation tank A in order to improve the exchange rate of solid-liquid sedimentation separation. A large number of descending slope plates 1 may be installed in a single stage or in multiple stages (two stages in the illustrated example). According to this, while the wastewater containing solid waste falls along the upper surface of the sedimentation slope plate 1 as indicated by the solid line arrow in the figure, the precipitation of the solid waste is promoted, while the clean water from which the solid waste has been separated is rises along the lower surface of the sinking inclined plate 1 as indicated by the broken line arrow in the figure. Therefore, the separation efficiency is improved compared to the natural sedimentation method.

Various methods have been proposed for attaching this type of sinking slope plate to the frame, but among these, the hook type shown in Figure 8 has been found to be convenient from the viewpoint of construction. Are known. That is, as shown in the figure, the hook-type sinking slope plate 1 is provided with hook-shaped hanging pieces 2 at multiple locations on its back surface, and these hanging pieces 2 are attached to the frame B. It is configured to be fitted and hooked from above to a support rod _B1 extending in the lateral direction (see Fig. 7). As is clear from FIG. 9, the hooking piece 2 is attached to the support rod B by cutting out a part of the bulge formed by press-molding a plate made of synthetic resin, aluminum, etc. ₁ to form a fitting recess 3 for hanging onto the sinking inclined plate 1.
Since it is integrated into the back of the camera, it has a box-like shape with an open top. Therefore, when the settling slope plate 1 is attached to the support rod B ₁ as shown in Fig. 7,
As shown in FIG. 9, due to the opening 4 and the internal space 5 of the box-shaped locking piece 2, which are opened when the bulging portion is partially removed when forming the locking piece,
The dirty water passage along the upper surface of the sedimentation slope plate 1 and the clean water passage along the lower surface thereof are connected, and as a result,
Dirty water W ₁ and clean water W ₂ meet at the communicating part,
The solid-liquid separation efficiency was reduced. In addition, in the above-mentioned installed state, the hooking piece 2 is located below the settling inclined plate 1 and has a bottomed box shape with _an open top surface. Dirt tends to accumulate, especially when the rib 6 has a groove-like cross section and is integrally formed so as to protrude toward the back side of the sinking slope plate 1, as in the sinking slope plate 1 shown in FIGS. 8 and 9. This tendency was remarkable when the above-mentioned hooking piece 2 was formed on the surface.

(Problems to be solved by the invention) The problems to be solved by the invention are that the solid-liquid separation efficiency decreases due to the confluence of dirty water and clean water, and that solid waste accumulates inside the hanging piece. The purpose is to prevent such incidents from occurring.

(Means for solving the problem) The means for solving the above problem is to separate the hanging piece from the sinking slope plate, provide a mounting seat on the sinking slope plate, and attach the above-mentioned hanging piece to this mounting seat. The pedestal of the provided hook is externally fitted in a positioned state.

(Function) According to the above means, the dirty water passage along the upper surface of the settling slope plate and the clean water passage along the lower surface thereof are completely separated by the settling slope plate, so that the dirty water and the clean water join together. Things will disappear. Therefore,
There is no need to worry about a drop in solid-liquid separation efficiency or accumulation of solid waste inside the hanging piece due to the merging of dirty water and clean water.

(Example) The hook 10 illustrated in FIG. A locking piece 13 forming a fitting recess 12 is provided.

The base 11 is provided with folded fitting pieces 111, 111 at both ends thereof. In addition, the above recess 1
2 is formed by cutting out a part of the bulge formed in the center of the pedestal 11, and its width L ₀ is the same as the above-mentioned support rod B ₁ (see Figures 7 to 9).
The dimensions are set to be the same or approximately the same as the diameter of the
In the illustrated example, a rising protrusion 112 is integrally provided at a predetermined location on the base 11, and at the location where this protrusion 112 is provided, the width L ₁ of the recess 12 is the same as that of the support rod B ₁ . It is smaller than the diameter.

On the other hand, as is clear from FIG. 1, the descending slope plate 1 to which the above-mentioned hook 10 is attached is provided with a mounting seat 7 formed to protrude from its lower surface. This mounting seat 7 is provided with protrusions 71, 71 at both ends thereof, and is provided with engaging portions 72, 72 at the center of each of the upper and lower ends, which protrude beyond the seat surface of this mounting seat 7. There is. Although the mounting seats 7 in the illustrated example are provided in a state of protruding to both sides of the ribs 6 of the descending inclined plate 1, they may be provided in locations where no ribs are provided, for example, between a plurality of ribs. However, if the mounting seat 7 is provided at a location where the rib 6 is provided as in the illustrated example, the mounting seat 7 at the rib 6 can be adjusted by making the height of the mounting seat 7 lower than the height of the rib 6. 7 acts as the above-mentioned engaging portion 72, and there is an advantage that there is no need to separately provide such an engaging portion on the mounting seat 7.

In the above, as shown in FIG. 2, the hook 10 is formed with a sinking slope by pushing the fitting pieces 111, 111 of the pedestal 11 into the protrusions 71, 71 of the mounting seat 7 while elastically deforming them and fitting them outwardly. It is attached to plate 1. In this attached state, the hook 10 is positioned in two mutually orthogonal directions. That is, as shown in FIG.
The fitting pieces 111, 111 of 1 are positioned by externally fitting in a holding manner, while the sinking inclined plate 1
In the vertical direction, the pedestal 11 is positioned by engaging the end surfaces of the pedestal 11 with the engaging portions 72, 72 of the mounting seat 7, as shown in FIG.

The above-mentioned mounting seats 7 are provided at a plurality of locations on the lower surface of the descending inclined plate 1. FIG. 4 shows that two mounting seats 7 are provided at each of the upper and lower portions of the lower surface of the descending slope plate 1, and the hooks 10 attached to these mounting seats 7 are hung on support rods _B1 , one each on the upper and lower sides. It shows the stopped state.

In the descending inclined plate 1 arranged in this way, the hooking piece 13 is attached to a pedestal 1 separate from the descending inclined plate 1.
1, and since the base 11 is externally fitted onto the mounting seat 7 of the descending slope plate 1, there is no passageway that communicates the internal space of the locking piece 13 with the upper surface of the descending slope plate 1. That is, since the clean water passage described with reference to FIG. This eliminates the possibility of merging with the flowing clean water, thereby preventing a decrease in the efficiency of solid-liquid separation, and there is no possibility that solid waste will accumulate in the internal space of the hook 13 of the hook 10.

Since the hook 10 according to this embodiment is provided with the projecting piece 112 as explained with reference to FIG. ₁ , as is clear from FIG. Piece 112 is support rod B ₁
It faces in the exit direction. Therefore, even if a force in a lifting direction is applied to the sinking slope plate 1, the projecting piece 112 acts as a stopper to prevent the sinking slope plate 1 from falling off. A similar effect can also be achieved by providing a protruding piece 131 on the hooking piece 13 as shown in FIG. In addition, as shown in FIG.
Projection piece 1 raised from pedestal 11 at the entrance of
13 is provided, and the tip of this protruding piece 113 is attached to the hooking piece 13.
The same effect as described above can also be obtained by elastically locking the inner surface of the distal end portion.

In order to hang the hook 10 equipped with the projecting piece 112 shown in FIGS. 1 to 3 on the support rod B ₁ with the hook 10 attached to the sinking slope plate 1, the rib 6 of the sinking slope plate 1 must be attached to the support rod B ₁ . 1, so that the entrance of the recess 12 of the hook 10 faces the support rod _B1 , and then the descending slope plate 1 is pushed down. In this way, after the projecting piece 112 is elastically deformed inward by the support rod B ₁ , when it gets over the support rod B ₁ , it is restored to its original state and the latching piece 13 is moved as shown in FIG. It is hung on support rod B ₁ . The same applies to the protrusion 131 of the hook 10 in FIG. 5 and the protrusion 113 of the hook 10 in FIG. 6.

In the hook 10 shown in FIG. 5, a guide portion 132 is provided inside the tip of the hooking piece 13 and is inclined to expand outward. If you do it this way,
By simply aligning the recess 12 of the hook ₁₀ with respect to the support rod B 1 and facing it roughly, the guide portion 132 will come into contact with the support rod B ₁ and the support rod B ₁ will be drawn into the recess 12. Therefore, use the support rod for the settling slope plate 1
B ₁ has the advantage of being easily supported.
This point is important when hooking the hooks 10 attached to multiple locations on the descending slope plate 1 to the support rod _B1 .
This is advantageous in preventing some of the hooks 10 from being left unlatched to the support rod _B1 .

(Effects of the invention) The hook of the present invention is attached to the sinking slope plate by externally fitting its pedestal onto the mounting seat of the sinking slope plate, so that not only can the hook come into surface contact with the sinking slope plate, but the installation can be ensured without wobbling. As is clear from the examples, there is no need to form an opening in the descending slope plate to communicate the upper surface side and the lower surface side thereof.Therefore,
The dirty water flowing along the top surface of the sedimentation slope plate and the clean water flowing along the bottom surface no longer merge.
In addition, since solid dirt does not accumulate on the hanging piece of the hook, the solid-liquid separation efficiency does not decrease. Further, since there is no need to provide a hook piece integrally on the sinking slope plate, the price of the sinking slope plate is reduced, and it is advantageous for storing the sinking slope plates in a stacked manner. Nevertheless, the hook is securely positioned on the sinking ramp so that the sinking ramp does not fall off the hook during use.
