わめておおきい。(Problem that the invention aims to solve) When a large amount of contents are stored in a conventional wastewater treatment facility, such as a sludge sump or a hopper for storing raw materials, and later taken out, considerable pressure is applied to the contents. In the past, fluidity has been lost, and especially when solidification occurs due to drying or deliquescence, or solidification or other changes occur (hereinafter simply referred to as solidification), the entire inside of the hopper becomes lumpy, so the contents may be When taking out the container, there were many problems where the contents would not come out even if the outlet was opened, and it was necessary to break it in some way.
It was customary to spend a considerable amount of time and effort each time it was discharged. Even if the side walls of the hopper were made vertical and the entire bottom of the discharge port was opened, the frictional resistance between the contents and the wall surface would be reduced and the contents would fall more easily, but the amount of contents in the hopper would be Normally, this is in units of several tons, so if it falls all at once, it is extremely dangerous, as it can damage conveyors and vehicles that receive it below, or cause problems such as falling objects spilling out.

要である。 Ideas and applications proposed to solve these problems (Sho 59)
-53485 is much more effective than the conventional hopper, but depending on the contents of the hopper, it may still cause the solidification of the contents and its own weight.
As shown in FIGS. 5 and 6, when the contents of areas A, B, and B' are introduced into the hopper opening, the force is concentrated toward the discharge port 2. The lower portions of the partition plates 4, 4' are narrowed, and the vertically hung partition plates 4, 4' are no longer vertical, but the lid 5 of the lower outlet,
In some cases, problems such as the contents not falling out even when the partition plate 5' is opened, or one or both of the partition plates 4 and 4' being bent cannot be completely solved. Therefore, in order to solve this problem, it is important to suspend the partition plates 4, 4' vertically without swinging freely until the discharge port 2 is opened.
（問題点を解決するための手段）
本考案のホツパーの構造は、図面に示す如く下

４′の振れ止め部６，６′を取りつけたことを特徴
とする。(Means for Solving the Problems) The structure of the hopper of the present invention is as shown in the drawing, in the hopper 1 having a discharge port 2 at the bottom,
A plate-like sheet 4 is placed above the fulcrum 3, 3' of the opening.
4' is a hopper with a plate-shaped sheet 4 for partitioning the contents on the lid 5, 5' of the lower discharge port 2.
It is characterized in that steady rest parts 6, 6' of 4' are attached.
板状シート４，４′は第１図及び第２図に於い
て下部が左右に振子と同様の動きが可能なように
上部を固定する。ホツパー１の上方より落ち込む
汚泥等の内容物７は板状のシート４，４′によつ
て区切られた区域Ａ，Ｂ，B′のそれぞれになる
べく均等に収容出来るようにする。 The upper portions of the plate-like sheets 4, 4' are fixed so that the lower portions can move left and right in the same manner as a pendulum in FIGS. 1 and 2. Contents 7 such as sludge falling from above the hopper 1 are accommodated as evenly as possible in each of areas A, B, and B' divided by plate-like sheets 4 and 4'.
本考案に使用出来る板状のシート４，４′は軟
質でフレキシブルな物ではなく、硬質の板状のシ
ートを使用する必要がある。 The plate-shaped sheets 4, 4' that can be used in the present invention are not soft and flexible, but need to be hard plate-shaped sheets.

下せず、又シート４，４′にかかる摩擦が大きい
為にシート４，４′がすぐに破損してしまう。 If a flexible sheet such as a soft plastic film or a strong sheet called tarpaulin is used, the contents will accumulate as shown in Figure 6, and the discharge port will have to be opened. However, the contents accumulated in the area A do not fall smoothly, and the sheets 4, 4' are easily damaged because of the large friction applied to the sheets 4, 4'.
板状シート４，４′の材質は鉄板、トタン板、

何等問題無く使用出来ることが確認された。 The material of the plate-shaped sheets 4, 4' is iron plate, galvanized iron plate,
Various options are available, including stainless steel plates, metal plates such as aluminum, plastic plates such as hard vinyl chloride, hard polyethylene, and hard polypropylene, and wooden plates. If the contents are corrosive, a metal one is not appropriate, and it is necessary to choose one to which the contents do not easily adhere. The results of experiments using hoppers at industrial wastewater sludge treatment facilities that mainly use dry non-woven fabrics show that iron plates have less sludge cake adhesion, and if the iron plate is 4 mm or more thick, it can hold 10 tons of content. It was confirmed that Hopper can also be used without any problems.
更にシート４，４′の形態についても前記汚泥
処理施設で実験を繰り返した処、平板な鉄板のほ
うが波板状の鉄板よりも汚泥の付着も少なく良い

口しないで内容物７を溜め込む時点で互いに接近
する状態となつたり、或いは排出口２を開口した
時に同様の状態となつて、内容物７が詰まつてし
まい排出されない場合もある。 Furthermore, experiments were repeated at the sludge treatment facility regarding the form of the sheets 4 and 4', and better results were obtained with flat iron plates, with less sludge adhesion than with corrugated iron plates. Furthermore, as a result of repeated experiments under various practical conditions, it was found that the contents 7 were stored in the lower parts of the plate-shaped sheet bodies 4 and 4' without opening the discharge ports 2, as shown in FIGS. 5 and 6. They may come close to each other at the same time, or a similar situation may occur when the discharge port 2 is opened, causing the contents 7 to become clogged and not be discharged.
この問題を解決する為に第１図、第２図及び第
３図に示す如く、振れ止め部６，６′を設けて解
決したものである。 In order to solve this problem, steady rest parts 6, 6' are provided as shown in FIGS. 1, 2, and 3.
振れ止め部６，６′は内容物７と化学反応した
りするものであつてはならないが、板状のシート
体４，４′と同程度の強度を有するものを使えば
良く、又内容物の付着しずらいものを使用するこ
とが好ましい。 The steady rest portions 6, 6' must not react chemically with the contents 7, but they should be of the same strength as the plate-like sheet bodies 4, 4', and should not react chemically with the contents 7. It is preferable to use a material that is difficult to adhere to.
振れ止め部６，６′の形状は特に限定するもの
ではないが、排出口２を閉じた状態即ち蓋５，
５′を閉じた状態の時には板状シート４，４′がそ
の上部を支点として自在に振れるようにしなけれ
ばならない。 Although the shape of the steady rest parts 6, 6' is not particularly limited, it can be used when the discharge port 2 is closed, that is, the lid 5,
When the plate 5' is in the closed state, the plate-like sheets 4, 4' must be able to swing freely using the upper part as a fulcrum.
振れ止め部６，６′の構造の一例としては、第
３図及び第４図に示す如く、蓋５，５′に三角板

止め部６，６′によつて完全に固定される必要性
は無く、振れに多少の遊びがあつても問題は無い
が、板状シート４，４′は略垂直に吊り下がつた
状態で固定される必要がある。 As an example of the structure of the steady rest parts 6, 6', triangular plates may be fixed to the lids 5, 5', as shown in FIGS. 3 and 4. The swing of the lower part of the plate-shaped sheets 4, 4' is within 5 cm with the lids 5, 5' closed.A steady rest is installed. That is, the sheet bodies 4, 4' do not need to be completely fixed by the steady rests 6, 6', and there is no problem even if there is some play in the swing, but the plate-like sheets 4, 4' must be fixed so that it hangs almost vertically.
強度上での問題も、例えば三角板を振れ止めに
設置する場合には、三角板の巾を拡げるか、三角
板の設置数を多くするかもしくはその両方を同時
に行うなどの方法で任意の強度に耐えるものをつ
くることができる。 There is also the issue of strength, for example, when installing a triangular plate on a steady rest, you can increase the width of the triangular plate, increase the number of triangular plates installed, or do both at the same time to withstand the desired strength. can be created.

る。(Function) The behavior of the hopper in the present invention when discharging the contents is that when the discharge port 2 is opened, the contents accumulated in area A are first discharged, and the lateral direction (B , B' direction), the lower part of either the plate-shaped sheet 4 or 4', which is released from the stop portions 6 and 6' of the side rest, is first pushed to the area A side. . If the lower part of the sheet 4 moves first, the contents accumulated in area B will be discharged following the contents accumulated in area A, and then the contents accumulated in area B' will be discharged. If the sheet 4' moves before the sheet 4, the contents will naturally be discharged in the order of zone B' and zone B.
内容物７が全部落下した後、蓋５，５′を閉じ

4' need not each be one sheet.
A plurality of plate-shaped sheets may be connected or their ends may be overlapped, or they may be hung with some gap as shown in FIG. 4. Although it depends on the size of the hopper, it is more preferable to use several commercially available standard products than to use water-sized iron plates in terms of durability and also in terms of economy.
