Description

  The present invention relates to an inclined plate support and an inclined plate support structure using the inclined plate support.

  Conventionally, as a solid-liquid separator provided in a water purification plant or the like, a solid-liquid separator using an inclined plate as shown in Patent Document 1 has been used. As shown in FIGS. 11 to 12, the solid-liquid separation device 100 is configured such that a large number of inclined plates 101 are provided in one or more stages on a frame B provided in a sedimentation basin A, The sedimentation of solid waste is promoted while descending along 101, and the clean water from which the solid waste is separated rises along the back surface of the inclined plate, thereby preventing re-disturbing of the clean water and solid waste, Separation efficiency is improved compared to the case of the natural sedimentation method.

  As shown in FIGS. 11 to 13, the inclined plate 101 used in the solid-liquid separator is suspended from a support rod 102 attached to the frame B by a hook 103 formed integrally with the inclined plate 101. Has been lowered. As shown in FIG. 11, the hooks 103 are provided in the vicinity of the four corners of the substantially rectangular inclined plate 101, and the inclined plate 101 provided with the hook 103 is inclined by vacuum forming at a factory or the like.

  However, as shown in FIG. 12, the inclined plate 101 a provided at the end of the settling basin A needs to be shorter than the inclined plate 101 b provided at the center of the settling basin A. In this case, the inclined plate 101b can be installed by cutting on site, but when the inclined plate 101b is cut, the hook 103 on the upper or lower portion of the inclined plate 101b is also cut. There is a problem that it cannot be attached to the support rod 102 at the end. Therefore, conventionally, it is necessary to prepare a separate mold for the inclined plate 101a for the inclined plate 101a, and there is a problem in that costs increase.

  Further, the vertical interval L of the frame B shown in FIG. 12 for each settling basin may vary depending on the site, and an inclined plate manufactured with one mold for a certain settling basin (for example, L = 2 m). 101 cannot be used in other sedimentation basins (for example, L = 1.5 m) having different L2. That is, the vertical distance L of the frame B and the distance (L2) between the hooks 103 are in a proportional relationship (three square theorem), and when L changes, the distance between the hooks 103 also changes. There is a problem that the inclined plate 101 manufactured in the above cannot be used in common at a plurality of sites.

  Therefore, in view of the above problems, the present invention, due to the depth of the sedimentation basin, required processing capacity, installation position, etc., even if the size of the inclined plate or the distance between the hooks of the inclined plate changes, It is an object of the present invention to provide a novel inclined plate support and an inclined plate support structure using the inclined plate support that make it possible to use inclined plates formed using the same mold.

  Hereinafter, an inclined plate support according to the present invention and an inclined plate support structure using the inclined plate support will be described in detail with reference to the accompanying drawings.

  As shown in FIG. 1, the inclined plate support 1 of the present invention is detachably attached to the four corners of the inclined plate 2. Through the inclined plate support 1 attached to the inclined plate 2, the inclined plate 2 connects a pair of upper and lower support frames 31a, 31b, 32a, 32b provided in parallel to each other in a sedimentation basin (not shown). The plurality of support bars 4 are locked. In addition, “inclined plate” means a state inclined in a sedimentation basin as shown in FIG. 1 in order to efficiently settle suspended solids in facilities requiring water treatment such as water purification plants and sewage treatment plants. Means a flat plate arranged in The material of the inclined plate 2 is not particularly limited, but a thermoplastic resin, for example, a vinyl resin such as polyvinyl chloride, a carbonate resin such as polycarbonate, an ester resin such as polyethylene terephthalate, a polymethyl methacrylate, etc. It may be an acrylic resin, an olefin resin such as polypropylene or polyethylene, a styrene resin such as ABS, or a copolymer or mixed resin thereof, or a thermosetting resin such as an epoxy resin or an unsaturated polyester resin. It may be metal, ceramic, wood, rubber or the like.

  Further, the inclined plate 2 may be provided with ribs 21 along the vertical direction X shown in FIG. 1 in order to increase the rigidity in the vertical direction and suppress the bending of the inclined plate 2 itself. In FIG. 1, the rib 21 has a groove shape along the vertical direction X.

  As shown in FIG. 2, the inclined plate 2 is supported diagonally by upper and lower support bars 4. For example, the angle θ between the inclined plate 2 and the lower support frames 31 b and 32 b is 50 to 70 °. More preferably, it is supported so as to be 60 °, and the pitch L3 between the inclined plate 2 and the inclined plate 2 is arranged to be 70 to 120 mm. The arrangement angle θ and the pitch L of the inclined plate 2 vary depending on the site where the inclined plate 2 is disposed, and can be changed as appropriate.

  Next, the structure of the inclined plate support 1 will be described with reference to FIG. As shown in FIG. 3, the inclined plate support 1 includes an inclined plate support main body (hereinafter simply referred to as a main body) 11, a hook portion 12 that protrudes integrally on one side of the main body 11, and a main body. 11 is a latching portion 13 for latching the inclined plate support 1 provided integrally with the main body 11 on the inclined plate 2 on the other side, that is, the side facing the inclined plate 2 when attached to the inclined plate 2. It consists of and. The inclined plate support 1 is made of the same material as that of the inclined plate 2, and the material can be selected as appropriate.

  3 and 4, the latching portion 13 is provided integrally with the latching projection 14 protruding from the main body 11 and the main body 11, and when the latching projection 14 is latched on the inclined plate 2. Further, the plate spring 15 is configured to prevent the inclined plate support 1 from coming off by the spring bias.

  The main body 11 itself has a flat shape as a whole, and its height H is about 5 to 15 mm, which is substantially the same as the depth (height) of the rib 21 provided on the inclined plate 2. . As shown in FIG. 4, the body 11 is provided with a hollow portion 11 a so that the leaf spring 15 can escape when the leaf spring 15 is biased toward the body 11.

  Engaging protrusions 12a and 12b are provided on the hook part 12 that protrudes integrally from the main body 11 so that the hook part 12 is difficult to come off when the hook part 12 is attached to the support rod 4 disposed in the sedimentation basin. In addition, the hook portion 12 may have any shape as long as it can be attached to the support bar 4.

  The latching protrusion 14 includes a neck portion 14a that extends from the main body 11 and has a height substantially equal to or slightly higher than the thickness of the inclined plate 2, and a wide portion 14b that is wider than the neck portion 14a. 3 and 4, the neck portion 14a has an elongated column shape, but may have other shapes such as a columnar shape or a regular square column with a square cross section. As shown in FIGS. 3 and 4, the wide portion 14 b is a thin plate-like member that is wider than the neck portion 14 a so that the inclined plate support 1 does not come off the inclined plate 2. It is not limited and can be a substantially rectangular shape as shown in FIG. 3 or a circular shape. The thickness of the wide portion 14b can be about 1 to 3 mm in order to reduce the protruding portion, but is not limited to this value, and can be made thinner by using a high-strength material. It is. When the inclined plate support 1 is attached to the inclined plate 2, the wide portion 14b has a thin plate shape, so that almost no protruding portion from the inclined plate 2 disappears, and solid matter such as flocks traveling through the inclined plate 2 is inclined. It becomes difficult to deposit on the plate 2. Normally, flocs deposited on the inclined plate 2 travel down the upper surface of the inclined plate (the surface indicated by the reference sign US in FIG. 2) and fall to the bottom of the sedimentation basin. Since it tends to decrease, the thin plate-like wide portion 14b can prevent the processing capacity from decreasing.

  3 and 4, the leaf spring 15 extends from the main body 11 along the longitudinal direction of the elongated main body 11 (that is, the vertical direction X of the inclined plate 2 when the main body 1 is attached to the inclined plate 2). Shown as a spring. The free end 15b of the leaf spring 15 can be pivoted in the vertical direction on the paper surface of FIG. On the free end 15 b side of the leaf spring 15, the leaf spring 15 protrudes from the one surface of the main body 11 (the surface on which the latching protrusion 14 is provided) to the outside of the main body 11 in a state where the leaf spring 15 is not biased. A protruding portion 15c is provided.

  An example of the inclined plate 2 used with the inclined plate support 1 is shown in FIG. As shown in FIG. 5, the inclined plate 2 includes a plurality of groove-like ribs 21 and a flat plate-like portion 22 positioned between the groove-like ribs 21. In FIG. 5, a hooking hole 23 for fixing the inclined plate support 1 to the groove-like rib 21 is provided, but the hooking hole 23 may be provided in the flat plate-like portion 22. Is possible.

  FIG. 6 is an enlarged view of the latching hole 23 indicated by Y in FIG. 5, and the latching hole 23 is formed of a latching projection 14 for inserting the latching projection 14 as shown in FIG. The insertion opening 23a, which is wider than the wide part 14b and can penetrate the entire wide part 14b, and the wide part 14b of the latching protrusion 14 are inserted into the insertion opening 23a, and then the latching protrusion 14 The slit portion 23b has a narrow width for sliding the neck portion 14a. 5 and 6, the insertion opening 23a is illustrated as a substantially square opening. However, the insertion opening 23a is not particularly limited as long as the entire wide portion 14b of the latching protrusion 14 can be inserted. However, it may be a circular or rectangular opening into which a substantially square wide portion can be inserted, for example, as long as it is larger than the wide portion 14b. In FIG. 5, a narrow slit portion 23b is located on the upper side of the inclined plate 2 (upper side in FIG. 2) of the hooking hole 23, and the lower side of the inclined plate 2 (lower side of the paper in FIG. 2) A “convex” -shaped hooking hole 23 in which the insertion opening 23 a is continuously formed is formed on the side). By forming the slit portion 23b on the upper side of the inclined plate 2, the upper end edge of the slit portion 23b and the neck portion 14a of the latching protrusion 14 come into contact with each other, and the load of the inclined plate 2 can be supported (the slit portion 23b is If formed below the insertion opening 23a, the load of the inclined plate 2 must be supported only by the protrusion 15c of the leaf spring 15, and the leaf spring 15 may be deformed and the support 1 may be detached. ).

  5 and 6, two hooking holes 23 are provided for the installation location of the inclined plate support 1, but can be changed according to the number of the hook portions 13 of the inclined plate support 1. For example, in the case of one latching portion 13 shown in FIG. 3 (one latching projection 14 and one leaf spring 15), one latching hole 23 can be used, When three hooks 13 are provided on the inclined plate support 1, the hook holes 23 may be three.

  Further, in FIG. 5, the positions at which the inclined plate support 1 is hooked are the four corners of the inclined plate 2, but the positions at which the inclined plate support 1 is hooked can be increased and are limited to the four corners. is not.

  Next, a method for attaching the inclined plate support 1 of the present invention to the inclined plate 2 will be described with reference to FIGS.

  The state shown in FIG. 7A and FIG. 8A is a state before the inclined plate support 1 is attached to the inclined plate 2, and when the inclined plate support 1 is attached to the inclined plate, the inclination is first inclined. The latching protrusion 14 of the inclined plate support 1 is positioned at a position corresponding to the insertion opening 23a of the latching hole 23 of the plate 2 (see FIGS. 7A and 8A).

  From this state, when the inclined plate support 1 is moved to the inclined plate 2 side, the latching projection 14 is inserted into the insertion opening 23a, and at the same time, the inclined plate 2 and the free end 15b of the leaf spring 15 abut, When the inclined plate support 1 is moved to the inclined plate 2 side even after contact, the free end 15b is pressed by the inclined plate 2 and elastically deformed to the cavity 11a side (upper side of the drawing) of the main body 11 (FIG. 7). (See (b) and FIG. 8 (b)).

  From this state, the latching protrusion 14 inserted into the insertion opening 23a is slid to the slit 23b side of the latching hole 23, and the neck 14a of the latching protrusion 14 slides in the slit 23b. When the free end 15b of the leaf spring 15 is elastically deformed and slides with a biasing force in the direction of the inclined plate 2, and the free end 15b is positioned on the insertion opening 23a, the elastically deformed leaf spring 15 The free end 15b enters the insertion opening 23a by the urging force in the direction of the inclined plate 2 and returns to the original state (the state in which the elastic end is not elastically deformed). The inclined plate support 1 is attached to the inclined plate 2 by being locked to the insertion opening 23a (see FIGS. 7C and 8C).

  Moreover, when removing the inclination board support 1 from the inclination board 2, it is possible to remove easily by the reverse process to the above-mentioned process. That is, it is possible to easily separate the locking projection 14 by sliding the locking projection 14 while pressing the protruding portion 15c and removing the locking projection 14 from the insertion opening 23a.

  As described above, by using the inclined plate support 1 of the present invention, attachment to the inclined plate 2 is facilitated. In addition, since the hook connected to the support bar 4 is not integrally formed with the inclined plate 2, the inclined plate 2 is cut at the site or at a factory, and a hole for latching is formed in the inclined plate 2 after the cutting. It is possible to attach the inclined plate 2 to the support bar 4 by attaching the inclined plate support 1. Therefore, it is not necessary to prepare a long inclined plate and a short inclined plate, and it is not necessary to raise a mold according to the size, so that the cost can be greatly reduced.

  In addition, since the hook and the inclined plate 2 are not integrally molded, the settling pond in which the inclined plate 2 is installed is changed, and the distance between the support frames is changed, so that the necessary between the hooks of the inclined plate 2 is changed. Even if the distance fluctuates, the mounting position of the inclined plate support 1 can be easily changed, so there is no need to create a mold corresponding to the distance between the hooks of the inclined plate 2 and the cost is greatly reduced. can do.

  In addition, when the inclined plate support 1 is attached to the inclined plate 2 via a hooking hole provided in the groove-shaped rib and the height of the main body 11 is matched with the height of the groove-shaped rib, the inclined plate support Since the hook 1 is the only portion that protrudes from the flat plate portion of the inclined plate 2, the protruding portion that obstructs the water flow in the settling basin can be reduced to the minimum, and the resistance of the water flow can be reduced to the minimum In addition, floc deposits can be reduced to a minimum. Normally, the floc deposited on the inclined plate 2 falls to the bottom of the sedimentation basin along the upper surface of the inclined plate. However, if the protruding portion is large, the floc accumulates and the processing capacity tends to decrease. A decrease in processing capacity can be prevented.

  Further, when the inclined plate support 1 is attached to the inclined plate 2, the wide portion 14 b of the latching protrusion 14 hardly protrudes from the surface of the inclined plate 2, and the protruding portion 15 c of the leaf spring 15. Hardly protrudes from the inclined plate 15, so that flocs in the sedimentation basin hardly accumulate on the inclined plate support 1.

  Further, the inclined plate 2 is formed such that the side from which the rib 21 protrudes from the flat plate-like portion 22 of the inclined plate 2 is the upper surface US side of the inclined plate 2, and the recessed portion is grooved below the inclined plate 2. As shown in FIG. 1, the flat plate-like portion 22 of the inclined plate 2 and the support bar 4 come into contact with each other, so that the contact area between the support bar 4 and the inclined plate 2 is increased as compared with the conventional case. Therefore, the strength of the entire inclined plate 2 can be increased.

  Although the inclined plate support 1 of the present invention is firmly fixed to the inclined plate 2 as described above, by further providing the inclined plate support 1 with a tapered portion 5 as shown in FIG. Further, it is possible to make it difficult to remove the inclined plate support 1 from the inclined plate 2. The inclined plate support 1 shown in FIGS. 9A to 9C is the same as the inclined plate support 1 shown in FIG. 3 and the like except that the tapered portion 5 is provided. Omitted.

  As shown in FIGS. 9A to 9C, the main body 11 of the inclined plate support 1 extends along the longitudinal direction of the main body 11 and extends toward the joint portion between the hook portion 12 and the main body 11. 16 from the free end side of the extension portion 16 to the curved portion 12c where the support bar 4 of the hook portion 12 is supported, the free end side of the extension portion 16 is low, and the curved portion 12c side of the hook portion 12 is A tapered portion 5 formed to be higher is provided. In FIG. 9, the taper portion 5 has a triangular plate shape and is disposed perpendicular to the flat extension portion 16. In FIG. 9, the curved portion 12 c of the hook portion 12 is formed so that the portion where the support rod 4 is supported is curved. However, the term “curved portion” means that the support rod 4 of the hook portion 12 is curved. The concept includes a flat surface of the outer portion of the supported portion, and the tapered portion 5 can be provided on the flat outer surface. The tapered portion 5 is linear when the inclined plate support 1 is viewed from the side, but may be a curved tapered portion, and the entire tapered portion 5 is formed in a curved shape. It may be.

  Next, the function of the tapered portion 5 will be described with reference to FIG. As shown in FIG. 10, when the inclined plate 2 is attached to or removed from the support bar 4 on which the inclined plate 2 is supported, the inclined plate 2 and the support bar 4 have a relationship as shown in FIG. 10. . When the inclined plate 2 is moved upward in FIG. 10 at this time, when the tapered portion 5 is not formed, the support bar 4 comes into contact with the curved portion 12 c of the inclined plate support 1, and the inclined plate support 1 Since a downward stress is directly applied, a force in a direction in which the inclined plate support 1 is detached from the inclined plate 2 is applied. By providing the taper portion 5 at a position that covers part or all of the curved portion 12 c of the hook portion 12 of the inclined plate support 1, the force from the support bar 4 can be received, so that the inclined plate support 1 is connected to the inclined plate 2. The risk of falling off can be further reduced. The shape of the taper portion 5 is not limited to the shape shown in FIG. 12, and the force applied in parallel to the inclined plate 2 from the support bar 4 that contacts the curved portion 12 c of the hook portion 12 is directed in the other direction. The shape is not particularly limited as long as it can reduce the component force applied in parallel to the inclined plate 2. For example, the taper part 5 may be provided over the entire width direction of the hook part 12. That is, it has the taper part 5 extended along the longitudinal direction of the inclined plate support 1 from the curved part 12c of the hook part 12, and the height of the taper part 5 is high as the curved part 12c side is separated from the curved part 12c. The taper part should just be formed so that it may become low. Further, the taper portion 5 can increase the strength of the hook portion 12 itself.
