Description

本発明に係る阻集器は、貯留槽本体と、この貯留槽本体には、少なくとも、排水が流れ込むバスケットと、水と油の比重差を利用して油脂類を浮上分離させる分離室と、排水を下水管へ流出させる流出口と、この流出口に設けられ、その下流からの臭気や虫の侵入を防ぐトラップとを備えており、少なくとも、バスケットの底面または下方のいずれか一つには整流板が設けられ、バスケットの下流側には、分離室と隔てる隔壁が設けられて、バスケットが設けられる前記貯留槽本体内のスペースを排水流入室となし、隔壁には、排水流入室に流入した排水が分離室へ流入する開口部が設けられ、この開口部の下端部は、標準水位面によりも高い位置に設けられた越流部であることを特徴とする。 The interceptor according to the present invention includes a storage tank body , at least a basket into which the drainage flows, a separation chamber for floating fats and oils using the difference in specific gravity of water and oil, and drainage water. An outlet for draining to a drain, and a trap provided at the outlet for preventing odors and insects from entering the downstream , and at least one of the bottom surface and the lower portion of the basket being a straightening vane And a partition separating the separation chamber is provided on the downstream side of the basket, and the space in the storage tank main body where the basket is provided is a drainage inflow chamber, and the partition drains the drainage flowed into the drainage inflow chamber Is provided with an opening which flows into the separation chamber, and the lower end of the opening is an overflow portion provided at a position higher than the standard water level surface .

本発明によれば、バスケットの底面あるいは下方に整流板が設けられていることにより、排水流入室に流入した油脂類を含む排水が勢いよく貯留槽深くまで潜り込むことを防ぐ。そして、整流板によって勢いが緩められた排水は、排水流入室内で浮上した油脂類を撹拌することなく、油脂類は細かくせん断されにくくなる。 According to the present invention, by providing the straightening vanes on the bottom surface or the lower side of the basket, the drainage containing the oil and fats which has flowed into the drainage inflow chamber is prevented from rushing deep into the storage tank. Then, in the drainage whose momentum is relaxed by the straightening vanes, the fats and oils are less likely to be finely sheared without stirring the fats and oils that have floated up in the drainage inflow chamber.

また、越流部は堰の役割を果たすため、排水流入室からは堰を超えた一定量の排水が分離室へと流れこみ、流れ方向に対して均一な流れに整えられる。また、越流部は標準水位面よりも高い位置にあるため、排水の流入がストップしても、分離室で浮上分離した油脂類が排水流入室へ逆戻りすることがない。 In addition, since the overflow section plays a role of a weir, a certain amount of drainage beyond the weir flows from the drainage inflow chamber into the separation chamber, and is arranged in a uniform flow in the flow direction. Further, since the overflow section is at a position higher than the standard water level surface, even if the inflow of drainage is stopped, the oils and fats floated and separated in the separation chamber do not return to the drainage inflow chamber.

また、本発明に係る阻集器は、少なくとも、バスケットの下流側面、隔壁の開口部上端、バスケットの下流側面と隔壁の間のいずれか一つには邪魔板が設けられていることを特徴とする。 The baffle according to the present invention is characterized in that at least one of the downstream side of the basket, the upper end of the opening of the septum, and the downstream side of the basket and the septum is provided with a baffle. .

新しいＳＨＡＳＥ規格により、阻集器の貯留槽本体への許容流入流量には制限がなく、一時に大量の排水が貯留槽の排水流入室へと流入する場合がある。その際には、排水は勢いあまって、バスケットの前面から直接隔壁の越流部の上を乗り越えて分離室へと流入してしまうこともあり、勢いのある排水が、分離室上に浮上分離された油脂類に衝突し、油脂類が撹拌され、細粒化されてしまう。また、越流部で排水が越流しない場合、排水は均一な流れに調整される機会を失い、流速にムラが生じ、分離効率が下がってしまう。本発明の邪魔板は、隔壁の越流部を越流することなく飛び越えて分離室へと入り込むのを防いで、そうした事態を防ぎ、排水流入室へと流入した排水は必ず隔壁に設けられた越流部を越流するように排水を案内するのである。 According to the new SHASE standard, there is no limitation on the allowable inflow rate of the interceptor into the storage tank body, and a large amount of drainage may flow into the drainage inflow chamber of the storage tank at one time. In this case, the drainage may be forced to move from the front of the basket directly over the overflow portion of the partition wall and flow into the separation chamber, and the drainage with momentum may be separated and floated on the separation chamber. It collides with the fats and oils which were made, and fats and oils are stirred and fine-grained. In addition, when drainage does not overflow in the overflow section, the drainage loses the opportunity to be adjusted to a uniform flow, causing unevenness in the flow velocity and lowering the separation efficiency. The baffle plate of the present invention prevents it from jumping over into the separation chamber without overflowing the overflow portion of the partition wall, thereby preventing such a situation, and the drainage flowed into the drainage inflow chamber is always provided in the partition wall The drainage is guided to overflow the overflow section.

さらに、隔壁のすぐ下流側には、もう一枚の隔壁が設けられ、下流側の隔壁と上流側の隔壁との間に、上流側の隔壁の開口部から流入する排水を分離室へ案内する流路を形成するとともに、下流側の隔壁の下端は、貯留槽本体の底から離れた位置に設けられて、分離室への連通空間を形成していることを特徴とする。 Furthermore, the immediately downstream side of the partition wall, another piece of the partition wall is provided, et al is, guided between the downstream side of the partition wall and the upstream side of the partition wall, the drainage that flows from the opening of the upstream side of the partition wall into the separation chamber The lower end of the downstream side partition wall is provided at a position away from the bottom of the storage tank main body to form a communication space to the separation chamber .

越流部を超えた排水は、２枚の隔壁の間を流路として、その狭い流路を案内されて、流れ方向に対して均一な流れを形成・維持されるとともに、上流の隔壁の越流部を超えた際に発生しやすい旋回流を発生しにくくできる。旋回流の発生をそのままにしておくと、油脂分と水と空気が撹拌され、泡状の油脂類が発生してしまい、阻集効率が下がってしまうためである。 Drainage beyond the overflow section is guided by the narrow flow path, with the flow path between the two partition walls being formed and maintained with uniform flow in the flow direction, and This makes it difficult to generate a swirling flow that is likely to occur when the flow section is crossed. If generation of the swirling flow is left as it is, the oil and fat, water and air are stirred, foamy oil and fats are generated, and the interception efficiency is lowered.

また、本発明の阻集器は、連通空間の下流には、貯留槽本体の底部から立ち上がる誘導板が設けられていることを特徴とする。また、誘導板は、貯留槽本体の底部から下流側に向かって傾斜させてもよい。 Further, the interceptor according to the present invention is characterized in that a guide plate rising from the bottom of the storage tank main body is provided downstream of the communication space . The guide plate may be inclined from the bottom of the storage tank body toward the downstream side.

本発明によれば、排水に含まれる油脂類は、誘導板に流れが案内されて分離室の表面へと浮上しやすくなる。誘導板がない場合、排水は排水流出室の下部にある連通空間から流出口までの最短距離となる貯留槽の底部を流れようとするのであるが、誘導板によって排水の流れが長くなり、より浮上分離しやすくなるのである。 According to the present invention, the oils and fats contained in the waste water can be guided by the guide plate to the surface and easily float on the surface of the separation chamber. If there is no induction plate, drainage attempts to flow through the bottom of the storage tank, which is the shortest distance from the communication space in the lower part of the drainage outflow chamber to the outlet, but the induction plate lengthens the drainage flow, and It becomes easy to float and separate.

さらに、本発明に係る阻集器は、トラップの周囲には、少なくとも三面を有する立体の隔壁を貯留槽本体の側壁に係止させ、この隔壁によって囲まれたトラップの周囲の空間を排水流出室となし、排水流出室を画する隔壁の下部には切欠を設けて連通空間となし、この連通空間によって、分離室からの排水が排水流出室へ流入することを特徴とする。Furthermore, according to the present invention, the three-dimensional partition wall having at least three sides is locked to the side wall of the reservoir body around the trap, and the space around the trap surrounded by the partition wall is a drainage outflow chamber A notch is provided in the lower part of the partition which defines the drainage outflow chamber to form a communication space, and the communication space is characterized in that drainage from the separation chamber flows into the drainage outflow chamber.

本発明によれば、排水流出室を形成する隔壁は、分離室に浮上した油が排水流出室内へ入り込まないように液密状に係止させることもできるし、あるいは筒状にして係止させることできる。さらに隔壁は、貯留層本体の左右幅一杯に広がるのでなくトラップの周囲を囲むので、分離室の容積をできるだけ大きく確保することができる。一般的にグリース阻集器において、貯留槽本体に占める油脂類を排水から分離させる分離室の表面積の割合はできるだけ大きい方が、同じ容量の貯留槽で比較すれば、油脂類の阻集効率は高くなる。 According to the present invention, the partition wall forming the drainage and outflow chamber can be locked in a fluid tight manner so that the oil floating in the separation chamber does not enter into the drainage and outflow chamber, or it is cylindrically locked It can be done. Furthermore, since the partition wall does not extend to the full width of the reservoir body, but surrounds the periphery of the trap, the volume of the separation chamber can be secured as large as possible. Generally in grease reservoirs, when the ratio of the surface area of the separation chamber for separating oil and fat in the storage tank from the drainage is as large as possible, the efficiency of oil and fat collection is higher when compared in a storage tank of the same capacity .

また、本発明に係る阻集器は、連通空間を、前記トラップへ排水が流入する位置より低い位置に設けていることを特徴とする。Further, the interceptor according to the present invention is characterized in that the communication space is provided at a position lower than the position where the drainage flows into the trap.

これによって、たとえトラップにおいてサイフォン現象（排水トラップ内の排水がすべて引っ張られて下流に引き込まれ、封水を破ってしまう破封現象）が起きても、分離室に浮上分離した油脂類は、隔壁に阻まれて排水流出室に流入することなく、油脂類が流出口から流出することを防ぐことができる。
As a result, even if siphon phenomenon occurs in the trap (a draining phenomenon in which all drainage in the drainage trap is pulled to be drawn downstream and tears the sealing water), fats and oils that have floated and separated in the separation chamber become partition walls. It is possible to prevent oil and fats from flowing out from the outlet without being blocked by it and flowing into the drainage outlet chamber.
