Description

【発明の属する技術分野】
本発明は、飲食店や食品加工場の排水設備等に設けられたグリース阻集器や、一般家庭や集合住宅の排水設備に設けられた升に溜まった油脂の固まりや汚泥、生ゴミを除去するのに使用される清掃器に関する。
【０００２】
【従来の技術】
飲食店や食品加工場の排水設備、特にグリース阻集器の清掃で、油脂除去や汚泥除去は大変な重労働である。この作業を軽減させる方法として、清掃器軸上部の握り柄部分に取付けられたてこを操作すると、軸下部に軸に対して左右に取付けられた一対のスコップが嵌合しゴミを掬い取ることができる清掃器が提案されている（例えば、特許文献１参照）。しかし、実際のところ飲食店や食品加工場では、調理用のカス揚げや柄付きザルおよび柄杓を使用して清掃しているところが大多数である。このような調理用のカス揚げや柄付きザルおよび柄杓は、その形状が丸形のため、阻集器や升の端、壁面を清掃するには適していないうえに、目が細か過ぎて水切れが悪く作業時間が長くなるという欠点も有している。
一方、グリーストラップ清掃用に販売している清掃器は、パンチングのサイズが大きいため、油脂や汚泥を掬ったときのゴミ捕捉性が悪いという欠点を有していた。

【発明が解決しようとする課題】
本発明は、水面に浮いた油脂類や汚泥を掬い取ることができ且つ水切れ性が良く作業が効率良く行なえるグリース阻集器や升の清掃器等の掬い取り清掃器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記課題を解決するため、四角形の底面とその３辺を囲む側面とからなる受け部と、この受け部の一側面に、底面に垂直方向に柄を取り付けてなる掬い取り器であって、受け部には円形または多角形の穴を有しており且つ穴の最大内接円の直径が１〜５ｍｍで円間距離が０．５〜５ｍｍである掬い取り清掃器が有効であることを見出し、本発明を完成した。
【０００６】
【発明の実施の形態】
以下、本発明について、特にその好ましい態様を中心に、詳細に説明する。
先ず、清掃器の受け部は、金網、円形や多角形のパンチングを施した金属板またはプラスチック板からなることが好ましく、そこに加工された穴の最大内接円は直径（以下、φと略記）１ｍｍ以上５ｍｍ以下の必要がある。グリース阻集器に溜まる油脂や汚泥はグリース阻集器第一槽に設置されたφ４〜５ｍｍのストレーナを通過したものが多いことから、最大内接円はφ５ｍｍ以下の大きさである必要がある。最大内接円がφ５ｍｍより大きいと汚泥が捕捉できなくなりゴミ捕捉性に劣る。また、最大内接円がφ１ｍｍより小さいと、油脂や汚泥で目が詰まり水切れ性が悪くなることから、φ１ｍｍ以上の大きさが必要である。好ましくは、最大内接円φ１〜３ｍｍ、更に好ましくはφ１〜２ｍｍである。
【０００７】
次に、円間距離は、０．５ｍｍ〜５ｍｍの必要がある。円間距離とは、開口部周間の最短距離のことをいう。円間距離が５ｍｍより大きいと汚泥の水切れ性が悪くなり、汚泥の形状によっては水を切るため受け部を四方八方に傾ける必要があるなど作業面で劣る。また、０．５ｍｍより小さいと油脂や汚泥の捕捉性が悪くなるうえに、耐荷重性に劣り実用性に欠ける。好ましくは、円間距離１〜３ｍｍ、更に好ましくは１〜２ｍｍである。
【０００８】
グリース阻集器の水面に浮いた油脂には、液体から固体とその粘性はさまざまである。このようなあらゆる状態の油脂を除去、特に液体の油を確実に掬い取るためには、受け部穴の最大内接円は小さく、開口率が４０％以内となるような円間距離とすることが好ましい。具体的には、φ１ｍｍ〜５ｍｍで円間距離０．５ｍｍ〜５ｍｍが、油脂除去に適している。
一方、グリース阻集器の底に溜まった汚泥には、受け部穴の最大内接円はφ５ｍｍ以下が好ましい。さらに水切り性を向上させるためには、φ２ｍｍ〜５ｍｍで、開口率３０〜６０％となるような円間距離０．５ｍｍ〜３ｍｍとすることが好ましい。
【０００９】
本発明の清掃器の受け部は、耐蝕性のあるステンレス、アルミニウムやプラスチックから構成されることが好ましい。一般的にグリース阻集器内の廃水は、食品等の影響によりｐＨ４〜５の酸性であり、このため酸性に対する耐蝕性を有することが好ましい。一方、飲食店厨房や食品加工場の清掃時にはしばしば苛性ソーダが使われる。この場合、排水は弱アルカリ性となるため、アルカリ性に対する耐蝕性を有することも好ましい。日本工業規格ＳＵＳ３０４、ＳＵＳ３１６が上記耐蝕性に優れている。ＳＵＳ３１６はクロルイオンに対する耐蝕性にも優れている。
次に、本発明品は四角形の底面とその３辺を囲む側面とからなる受け部と、この受け部の一側面に、底面に垂直方向に柄を取り付けてなる形状である。この概略図を図１と図２に示す。図１は汚泥掬い取り用、図２は油脂掬い取り用である。Ｌは受け部の長さ、Ｗは受け部の幅、Ｔは受け部の高さ、Ｈは柄の長さを表す。
【００１０】
グリース阻集器第三槽に設置されているトラップ管と壁面の隙間に溜まった汚泥を除去することは大変困難であり、この汚泥を除去することは下水道への負荷軽減に繋がる。汚泥用の幅（Ｗ１）は、グリース阻集器トラップ管と壁面の幅（Ｑ）から考慮して任意に設定できるが、（Ｑ）に対し百分率で６０〜８０％程度に設定するのが作業性の面から好ましい。一般的に（Ｑ）は約９０〜１３０ｍｍが好ましく、（Ｗ１）を６５ｍｍ〜９０ｍｍとするのが好ましい。汚泥を掬い上げる際、受け部を傾けると汚泥が流れ落ちず一度に多くの汚泥を捕捉することができる。このとき、長さ（Ｌ１）：高さ（Ｔ１）の相対比を１：０．８以上にすることが好ましい。本発明品の長さ（Ｌ１）寸法は、グリース阻集器幅から任意に設定することができるが、幅（Ｗ１）の１．５倍〜３倍が好ましく、更に好ましくは約２倍である。具体的には、（Ｌ１）を約１００〜２７０ｍｍ、（Ｔ１）を約８０〜２２０ｍｍとするのが好ましい。また、狭いエリア内でのハンドリングから、（Ｗ１）６５〜７５ｍｍ、（Ｌ１）１００〜１５０ｍｍ、（Ｔ１）８０〜１２０ｍｍが更に好ましい。柄の付いていない２側面が、底面に対し直角とすることで、グリース阻集器の隅及び壁面を隈なくかき取ることができ掬い取り性が飛躍的に向上する。
【００１１】
一方、グリース阻集器水面に広がった油脂を掬い取るには、受け部底面積が広いほうが作業性が向上する。本発明品の寸法はグリース阻集器のサイズに応じて任意に設定することができるが、高さ（Ｔ２）：幅（Ｗ２）：長さ（Ｌ２）の相対比１：２〜１０：２〜１０、幅（Ｗ２）：長さ（Ｌ２）の相対比１〜２：１〜２が好ましい。但し、受け部が大きすぎると捕捉できる汚泥量が多すぎ引き上げ難い。具体的には、汚泥の比重を１とした時、容積が２０００ｃｍ^３以下となるような寸法が好ましく、この場合（Ｔ２）は３０ｍｍ〜８０ｍｍ、（Ｗ２）と（Ｌ２）は１００ｍｍ〜３６０ｍｍとなる。また、狭いエリア内でのハンドリング面から、（Ｔ２）が４０ｍｍ〜５０ｍｍ、（Ｗ２）と（Ｌ２）が１５０ｍｍ〜２５０ｍｍが更に好ましい。また、汚泥用と同様に、底面に対し２側面を直角とすることで、掬い取り性が飛躍的に向上する。
【００１２】
柄は、受け部底面に対し垂直または受け部側に０〜１５度、好ましくは５〜１０度傾斜させた場合、重心が握り手の真下に来るため軽く持ち上げられる。材質は、耐蝕性の高いステンレスやアルミニウム、プラスチックからなるが、重量軽減させるため中空構造がよい。長さ（Ｈ）はグリース阻集器や升のサイズにより任意に設定できるが、一般には５０ｃｍ〜１５０ｃｍであり、６０ｃｍ〜１３０ｃｍにすると楽な姿勢で作業できることが多く好ましい。
【００１３】

先ず、各評価方法について説明する。
（１）最大内接円の直径（Ｍ：単位ｍｍ）
円や多角形の構造を拡大率１０倍で写真を３枚とり、各写真から１０個、計３０個の形の最大内接円をコンパスで描き、その直径を測定して平均値Ｍを求めた。
（２）開口率（Ｎ：単位％）
穴の面積が容易に求められる場合は、１０ｃｍ角板の面積に対する、その板に開いた穴部総面積の割合で開口率Ｎを求めた。穴の総面積が容易に求められない場合は、穴の開いた１０ｃｍ角板の複写を３枚紙にとり、紙から穴部を切り取りその重量から開口率を求め平均値Ｎを求めてもよい。

TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention removes a grease interceptor provided in a drainage facility of a restaurant or a food processing plant, or a mass of oils and fats accumulated in a drainage facility installed in a general household or an apartment house, sludge, and garbage. The present invention relates to a cleaning device used for:
[0002]
[Prior art]
Removing grease and sludge from cleaning drainage facilities in restaurants and food processing plants, especially grease interceptors, is a very heavy labor. As a method of reducing this work, when a lever attached to the handle handle at the upper part of the cleaner shaft is operated, a pair of scoops attached to the lower part of the shaft and left and right with respect to the shaft fit and scoop up dust. A cleaner that can be used has been proposed (for example, see Patent Document 1). However, in fact, in restaurants and food processing plants, most of them clean using fried foods for cooking, colanders with handles, and ladles. The round shape of such fried casks and ladle and ladle for cooking is not suitable for cleaning interceptors, ends of walls and walls, and the eyes are too fine to drain water. It also has the disadvantage that the working time is prolonged.
On the other hand, the cleaning device sold for cleaning the grease strap has a drawback in that since the punching size is large, the dust capturing property when scooping oils and fats or sludge is poor.
[0003]
[Patent Document 1]
Japanese Utility Model Publication No. Hei 4-22541
[Problems to be solved by the invention]
An object of the present invention is to provide a scooping and cleaning device such as a grease interceptor or a box cleaning device that can scoop oils and fats and sludge floating on the water surface and can perform work efficiently with good drainage. I do.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, there is provided a receiving portion including a square bottom surface and side surfaces surrounding three sides thereof, and a scooping device having a handle attached to one side surface of the receiving portion in a direction perpendicular to the bottom surface, It has been found that a scooping cleaner having a circular or polygonal hole in the part and having a maximum inscribed circle diameter of the hole of 1 to 5 mm and a distance between circles of 0.5 to 5 mm is effective. Thus, the present invention has been completed.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with particular emphasis on preferred embodiments.
First, the receiving portion of the cleaning device is preferably made of a metal mesh, a metal plate or a plastic plate subjected to circular or polygonal punching, and the maximum inscribed circle of the hole formed therein has a diameter (hereinafter abbreviated as φ). ) It is necessary to be 1 mm or more and 5 mm or less. Since most of the oils and sludge accumulated in the grease interceptor have passed through a φ4 to 5 mm strainer installed in the first grease interceptor tank, the maximum inscribed circle needs to be not larger than φ5 mm. If the maximum inscribed circle is larger than φ5 mm, sludge cannot be trapped and the dust trapping property is poor. If the maximum inscribed circle is smaller than φ1 mm, the clogging with oils and fats and sludge deteriorates water drainage, so that the size of φ1 mm or more is required. Preferably, the maximum inscribed circle is φ1 to 3 mm, more preferably φ1 to 2 mm.
[0007]
Next, the distance between the circles needs to be 0.5 mm to 5 mm. The distance between circles refers to the shortest distance between the circumferences of the openings. If the distance between the circles is larger than 5 mm, the sludge drainage becomes poor, and depending on the shape of the sludge, it is necessary to incline the receiving portion in all directions in order to cut off the water. On the other hand, if it is smaller than 0.5 mm, the ability to capture oils and fats and sludge will be poor, and the load resistance will be poor, and the utility will be poor. Preferably, the distance between the circles is 1 to 3 mm, more preferably, 1 to 2 mm.
[0008]
The oils and fats floating on the surface of the grease interceptor vary in viscosity from liquids to solids. In order to remove oils and fats in all such states, and in particular to reliably scoop liquid oil, the maximum inscribed circle of the receiving hole should be small and the distance between the circles should be such that the opening ratio is within 40%. Is preferred. Specifically, a diameter of 1 mm to 5 mm and a distance between circles of 0.5 mm to 5 mm is suitable for removing grease.
On the other hand, for the sludge collected at the bottom of the grease interceptor, the maximum inscribed circle of the receiving hole is preferably φ5 mm or less. In order to further improve the drainage property, it is preferable that the distance between the circles is 0.5 mm to 3 mm so that the opening ratio is 30 to 60% at φ2 mm to 5 mm.
[0009]
The receiving portion of the cleaning device of the present invention is preferably made of corrosion-resistant stainless steel, aluminum or plastic. Generally, the wastewater in the grease interceptor is acidic at pH 4 to 5 due to the influence of foods and the like, and therefore it is preferable that the wastewater has corrosion resistance to acidity. On the other hand, caustic soda is often used when cleaning restaurant kitchens and food processing facilities. In this case, since the wastewater becomes weakly alkaline, it is also preferable that the wastewater has corrosion resistance to alkalinity. Japanese Industrial Standards SUS304 and SUS316 are excellent in the above corrosion resistance. SUS316 is also excellent in corrosion resistance to chloride ions.
Next, the product of the present invention has a shape in which a receiving portion including a square bottom surface and side surfaces surrounding three sides thereof, and a handle attached to one side surface of the receiving portion in a direction perpendicular to the bottom surface. This schematic diagram is shown in FIG. 1 and FIG. FIG. 1 is for sludge scooping, and FIG. 2 is for oil and fat scooping. L represents the length of the receiving portion, W represents the width of the receiving portion, T represents the height of the receiving portion, and H represents the length of the handle.
[0010]
It is very difficult to remove the sludge accumulated in the gap between the trap tube and the wall installed in the third tank of the grease interceptor, and removing this sludge leads to a reduction in the load on the sewer. The width (W1) for sludge can be arbitrarily set in consideration of the width of the grease interceptor trap tube and the width (Q) of the wall, but the workability is set to about 60 to 80% as a percentage of (Q). It is preferable from the viewpoint of. Generally, (Q) is preferably about 90 to 130 mm, and (W1) is preferably 65 to 90 mm. When scooping up the sludge, if the receiving portion is tilted, the sludge does not flow down and many sludges can be captured at once. At this time, it is preferable that the relative ratio of length (L1): height (T1) is 1: 0.8 or more. The length (L1) of the product of the present invention can be arbitrarily set based on the width of the grease interceptor, but is preferably 1.5 to 3 times, and more preferably about 2 times, the width (W1). Specifically, it is preferable that (L1) is about 100 to 270 mm and (T1) is about 80 to 220 mm. From the handling in a narrow area, (W1) 65 to 75 mm, (L1) 100 to 150 mm, and (T1) 80 to 120 mm are more preferable. By making the two side surfaces without the handle perpendicular to the bottom surface, the corners and the wall surfaces of the grease interceptor can be scraped all over, and the scooping property can be greatly improved.
[0011]
On the other hand, in order to scoop up the oil and fat spread on the water surface of the grease interceptor, the workability is improved by increasing the bottom area of the receiving portion. The dimensions of the product of the present invention can be arbitrarily set according to the size of the grease interceptor, but the relative ratio of height (T2): width (W2): length (L2) is 1: 2 to 10: 2. 10, a relative ratio of width (W2): length (L2) of 1-2: 1-2 is preferred. However, if the receiving portion is too large, the amount of sludge that can be captured is too large and it is difficult to lift up. Specifically, when the specific gravity of the sludge is 1, the size is preferably such that the volume is 2000 cm ³ or less. In this case, (T2) is 30 mm to 80 mm, and (W2) and (L2) are 100 mm to 360 mm. . From the handling surface in a narrow area, (T2) is more preferably 40 mm to 50 mm, and (W2) and (L2) are more preferably 150 mm to 250 mm. In addition, as in the case of sludge, by making the two side surfaces perpendicular to the bottom surface, the scooping property is dramatically improved.
[0012]
When the handle is perpendicular to the bottom surface of the receiving portion or inclined at 0 to 15 degrees, preferably 5 to 10 degrees toward the receiving portion, the center of gravity is located directly below the grip, so that the handle can be lifted lightly. The material is made of stainless steel, aluminum or plastic having high corrosion resistance, but preferably has a hollow structure to reduce the weight. The length (H) can be arbitrarily set according to the size of the grease interceptor or the box, but is generally 50 cm to 150 cm. When the length is 60 cm to 130 cm, it is often preferable to work in a comfortable posture.
[0013]
The present invention will be described more specifically.
First, each evaluation method will be described.
(1) Diameter of the largest inscribed circle (M: mm)
Take three photographs of the structure of a circle or polygon at a magnification of 10x, draw a maximum of 30 inscribed circles from each photograph, a total of 30 shapes, with a compass, measure the diameter and find the average value M Was.
(2) Opening ratio (N: unit%)
When the area of the hole was easily determined, the aperture ratio N was determined by the ratio of the total area of the holes formed in the plate to the area of the 10 cm square plate. If the total area of the holes cannot be easily obtained, a copy of a 10 cm square plate having holes may be made on three sheets of paper, the holes may be cut out of the paper, the aperture ratio may be obtained from the weight, and the average value N may be obtained.
[0014]
(3) Scooping property and method In a tank-type grease interceptor filled with water, rice bran 1000 g and sky litter 1000 g are placed in two tanks having a capacity of 250 liters, an effective capacity of 16 liters, a length of 1000 mm, a width of 500 mm and a depth of 500 mm. (Referred to as model sludge, referred to as model litter in Table 1), and then oxidized by heating a mixture of 2: 2: 8: 1 of salad oil, sesame oil, lard, and water at 200 ° C. for about 30 minutes. 5 kg (referred to as model oil and fat) was floated and left for 1 hour. First, the model oils and fats floating in the two tanks were scooped up and removed by the cleaning device to be evaluated. Next, the model sludge settled at the bottom of the two tanks was scooped up and removed. The observation results at this time were determined according to the following criteria (model sludge and model oil and fat are collectively referred to as model soil).
