Description

この発明は、各種の液体の流路中に設けられるストレーナに装着されて、液体を通過させて液体中の固形物を除去するフィルタに目詰まりが生じた場合に、該フィルタを洗浄する洗浄装置に関する。   The present invention provides a cleaning device for cleaning a filter that is attached to a strainer provided in a flow path of various liquids, and that clogs the filter that passes the liquid and removes solids in the liquid. About.

例えば、飲料水や工業用水に固形物が含有されている場合には、飲用に適さず、あるいは工場での各処理水として利用することができない。このため、河川等から取水された水から固形物を除去する必要がある。また、工場等では各種の処理に利用された処理水を他の処理にも利用する場合には前工程での処理の際に混入した固形物を除去する必要がある。これら固形物を除去する装置としてストレーナが用いられることがある。この種のストレーナには、被処理水を通過させて固形物を除去させるフィルタが装着されている。なお、固形物を除去すべき対象は、水に限らず各種の処理液等がある。   For example, when a solid is contained in drinking water or industrial water, it is not suitable for drinking or cannot be used as each treated water in a factory. For this reason, it is necessary to remove solid matter from water taken from rivers. Moreover, in the factory etc., when using the treated water used for various processes also for another process, it is necessary to remove the solid substance mixed in the process in a previous process. A strainer may be used as an apparatus for removing these solid substances. This type of strainer is equipped with a filter that allows the treated water to pass through and removes solid matter. In addition, the object which should remove a solid substance is not only water but various processing liquids.

この種のフィルタに円筒型をした筒型のフィルタがあり、例えば特許文献１に記載された構造のように筒状の容器に筒型のフィルタを収容させ、被処理液をフィルタの外側から内側に通過させて、固形物が除去された被処理流体を取得するようにしている。   There is a cylindrical filter in this type of filter. For example, as in the structure described in Patent Document 1, the cylindrical filter is accommodated in a cylindrical container, and the liquid to be treated is transferred from the outside to the inside of the filter. The fluid to be processed from which the solid matter has been removed is obtained by passing it through the filter.

前記フィルタは固形物を除去することから、長時間使用することにより目詰まりが生じる。目詰まりが生じた場合にはフィルタの機能が低下すると共に、流路抵抗が大きくなり、圧力損失が増大するから、所望の量の被処理流体を処理することができなくなり、後続する処理工程等での円滑な処理を行えなくおそれがある。このため、フィルタを適時洗浄して目詰まりを解消する必要がある。   Since the filter removes solid matter, clogging occurs when it is used for a long time. When clogging occurs, the function of the filter decreases, the flow resistance increases, and the pressure loss increases, so that a desired amount of fluid to be processed cannot be processed, and subsequent processing steps, etc. There is a risk that smooth processing cannot be performed in For this reason, it is necessary to clean the filter timely to eliminate clogging.

前記特許文献１にはこの目詰まりを解消するためのフィルタの洗浄機能を備えたストレーナが開示されている。このストレーナは、ポンプに給液される液体中の固形物を濾過するフィルタと、該フィルタを洗浄する洗浄用圧液を前記フィルタの内側に導入する液導入部を有するストレーナにおいて、前記液導入部は、前記フィルタの内部で回転が可能であり、且つ前記洗浄用圧液を噴射し、該噴射の反力により自転力を発生する噴射口を有する自転体を備える構造としたものである。   Patent Document 1 discloses a strainer having a filter cleaning function for eliminating the clogging. The strainer includes a filter that filters solids in a liquid supplied to the pump, and a liquid introduction unit that introduces a cleaning pressure fluid for cleaning the filter to the inside of the filter. Is configured to include a rotation body that can rotate inside the filter and that has an injection port that injects the cleaning pressure liquid and generates a rotation force by the reaction force of the injection.

また、特許文献２には、円筒形網状構造部品洗浄装置として、フィルタエレメントの外形より大きい円周上に、２個の受けローラを固定して設けるとともに、１個の押えローラを移動自在に設け、フィルタエレメントの内径より小さい円周上に、軸方向に複数のノズルが一定間隔をもって配置された片持ち部材を、複数、前記ノズルの吐出方向が逆になるように、かつ、軸方向に設け、前記複数のノズルに高圧水の供給源を接続した構造が開示されている。   Further, in Patent Document 2, as a cylindrical mesh-structure cleaning device, two receiving rollers are fixedly provided on a circumference larger than the outer shape of the filter element, and one pressing roller is provided movably. A plurality of cantilever members in which a plurality of nozzles are arranged at regular intervals in the axial direction on a circumference smaller than the inner diameter of the filter element, and the discharge directions of the nozzles are provided in the opposite direction. A structure in which a high pressure water supply source is connected to the plurality of nozzles is disclosed.

特開２００６−３４１１６１JP 2006-341161 A 特開平８−１７３７２９号JP-A-8-173729

特許文献１に開示されたストレーナでは、ストレーナに装着した状態でフィルタを洗浄することができるものであり、バッチ処理を行う工程において、ストレーナの運転とフィルタの洗浄とを交互に行える場合等には適しているものであるが、定期的にフィルタを取り出して洗浄するものではない。   In the strainer disclosed in Patent Document 1, the filter can be cleaned while attached to the strainer, and in the process of batch processing, when the operation of the strainer and the cleaning of the filter can be performed alternately, etc. Although suitable, it is not intended to periodically remove and clean the filter.

また、特許文献２に記載された洗浄装置は、ストレーナから取り出したフィルタを洗浄する装置である。この洗浄装置では、ノズルから噴射される高圧水によってフィルタを回転させる構造とされたものである。しかし、ノズルはフィルタの内側に配されておりノズルから噴射される高圧水はフィルタの内壁に対して接線方向よりも大きな角度で衝突する。すなわち、フィルタの回転を高圧水の噴射により行う場合には、フィルタの壁体に対して接線方向に衝突させることが最も効率がよいが、特許文献２による構造ではノズルがフィルタの内側に配された構造とされているため、ノズルの噴射方向を接線方向に近づけることに限界があり、フィルタを回転させるための効率が低い。また、フィルタを支持するための受けローラや押えローラを必要として構造が複雑となり、部品点数が多く、洗浄装置が大型化するおそれがある。   Moreover, the washing | cleaning apparatus described in patent document 2 is an apparatus which wash | cleans the filter taken out from the strainer. In this cleaning apparatus, the filter is rotated by high-pressure water sprayed from a nozzle. However, the nozzle is arranged inside the filter, and the high-pressure water sprayed from the nozzle collides with the inner wall of the filter at an angle larger than the tangential direction. That is, when the rotation of the filter is performed by jetting high-pressure water, it is most efficient to collide with the filter wall in the tangential direction. However, in the structure according to Patent Document 2, the nozzle is arranged inside the filter. Therefore, there is a limit to bringing the nozzle injection direction close to the tangential direction, and the efficiency for rotating the filter is low. In addition, a receiving roller and a pressing roller for supporting the filter are required, the structure becomes complicated, the number of parts is large, and the cleaning device may be increased in size.

そこで、この発明は、ストレーナから取り外したフィルタを洗浄する際にフィルタを簡単に保持させるとともに、洗浄位置の変更のために簡単に確実に回転させることができる円筒型フィルタの洗浄装置を提供することを目的としている。   Therefore, the present invention provides a cylindrical filter cleaning device that can easily hold a filter when cleaning the filter removed from the strainer and can be easily and reliably rotated for changing the cleaning position. It is an object.

前記目的を達成するための技術的手段として、この発明に係る円筒型フィルタの洗浄装置は、壁体に被処理流体を通過させることにより、被処理流体に含まれている固形分を除去する円筒型のフィルタを、該フィルタが装着されたストレーナから取り出してフィルタに生じた目詰まりを解消するために洗浄する洗浄装置において、前記フィルタを遊嵌させる主洗浄管と、前記主洗浄管と平行に配した副洗浄管と、前記主洗浄管と副洗浄管のそれぞれに、長手方向に沿って複数の洗浄水噴射孔を設け、前記主洗浄管の洗浄水噴射孔の洗浄水噴射方向を該主洗浄管の径方向とし、前記副洗浄管の洗浄水噴射孔の洗浄水噴射方向を、主洗浄管に遊嵌させたフィルタの中心を通らず、該フィルタの外周面と交差する方向としたことを特徴としている。   As a technical means for achieving the above object, a cylindrical filter cleaning device according to the present invention is a cylinder for removing a solid content contained in a fluid to be treated by passing the fluid to be treated through a wall. In a cleaning apparatus that removes a filter of a mold from a strainer to which the filter is mounted to remove clogging generated in the filter, a main cleaning pipe in which the filter is loosely fitted, and a parallel to the main cleaning pipe A plurality of cleaning water injection holes are provided along the longitudinal direction in each of the arranged secondary cleaning pipe, and the main cleaning pipe and the secondary cleaning pipe, and the cleaning water injection direction of the cleaning water injection hole of the main cleaning pipe is the main cleaning pipe. The radial direction of the cleaning pipe and the cleaning water injection direction of the cleaning water injection hole of the sub-cleaning pipe do not pass through the center of the filter loosely fitted to the main cleaning pipe, but intersect the outer peripheral surface of the filter It is characterized by.

ストレーナから取り出された円筒型のフィルタを前記主洗浄管に遊嵌し、主洗浄管と前記副洗浄管のそれぞれの洗浄水噴射孔から洗浄水を噴射させる。主洗浄管の洗浄水噴射孔から噴射された洗浄水はフィルタの壁体の内周面に衝突して、目詰まりの原因となっている固形物を壁体の外周面に押し出す。外周面に押し出された固形物は、前記副洗浄管の洗浄水噴射孔から噴射された洗浄水により外周面から除去される。しかも、副洗浄管の洗浄水噴射孔から噴射された洗浄水は、主洗浄管の中心を通らず、フィルタの中心から偏倚した位置に衝突するため、フィルタを主洗浄管に対して回転させる。このため、主洗浄管の洗浄水噴射孔からの洗浄水はフィルタの回転に応じて徐々に噴射される位置が変化することになり、フィルタの全域にわたって目詰まりを解消することができる。   A cylindrical filter taken out from the strainer is loosely fitted into the main cleaning pipe, and cleaning water is sprayed from the cleaning water injection holes of the main cleaning pipe and the sub cleaning pipe. The cleaning water sprayed from the cleaning water injection hole of the main cleaning pipe collides with the inner peripheral surface of the wall of the filter, and pushes solid matter causing clogging to the outer peripheral surface of the wall. The solid material pushed out to the outer peripheral surface is removed from the outer peripheral surface by the cleaning water sprayed from the cleaning water spray hole of the sub cleaning pipe. Moreover, since the cleaning water sprayed from the cleaning water injection hole of the sub cleaning pipe does not pass through the center of the main cleaning pipe and collides with a position deviated from the center of the filter, the filter is rotated with respect to the main cleaning pipe. For this reason, the position where the washing water from the washing water injection hole of the main washing pipe is gradually ejected according to the rotation of the filter changes, and clogging can be eliminated over the entire area of the filter.

また、請求項２の発明に係る円筒型フィルタの洗浄装置は、前記主洗浄管の洗浄水噴射孔の洗浄水噴射方向が鉛直上向きであることを特徴としている。   Further, the cylindrical filter cleaning device according to the invention of claim 2 is characterized in that the cleaning water injection direction of the cleaning water injection hole of the main cleaning pipe is vertically upward.

主洗浄管の洗浄水噴射孔から鉛直上向きに洗浄水を噴射させるようにしたものである。主洗浄管の洗浄水噴射孔から洗浄水が噴射されることにより、該主洗浄管に遊嵌されているフィルタは、洗浄水の勢いを受けて偏倚して主洗浄管から離隔する。このとき、洗浄水を鉛直上向きとすることにより、フィルタが上方に偏倚して離隔する。このため、フィルタが主洗浄管から浮遊した状態となる。   The washing water is jetted vertically upward from the washing water injection hole of the main washing pipe. By flushing the washing water from the washing water injection hole of the main washing pipe, the filter loosely fitted in the main washing pipe is biased and separated from the main washing pipe due to the momentum of the washing water. At this time, by setting the washing water vertically upward, the filter is biased upward and separated. For this reason, the filter floats from the main cleaning pipe.

また、請求項３の発明に係る円筒型フィルタの洗浄装置は、前記副洗浄管の洗浄水噴射孔の洗浄水噴射方向が、主洗浄管の接線方向と平行な方向であることを特徴としている。   In the cylindrical filter cleaning device according to the third aspect of the present invention, the cleaning water injection direction of the cleaning water injection hole of the sub-cleaning pipe is parallel to the tangential direction of the main cleaning pipe. .

前記副洗浄管の洗浄水噴射孔の噴射方向が、主洗浄管の中心を通らないため、噴射された洗浄水の勢いは、主洗浄管に遊嵌されたフィルタを主洗浄管に対して回転させる力として作用する。このため、フィルタが主洗浄管に対して回転する。このとき、最も大きな回転力として作用させるためには、洗浄水がフィルタの径方向と直交する方向、すなわち接線方向に噴射されることが好ましい。そこで、副洗浄管の洗浄水噴射孔の噴射方向を主洗浄管の接線方向と平行な方向とし、主洗浄管に遊嵌されたフィルタに大きな回転力を作用させるようにしたものである。なお、副洗浄管の洗浄水噴射孔から噴射された洗浄水は、極力フィルタの外周側に衝突させることが好ましい。   Since the injection direction of the cleaning water injection hole of the secondary cleaning pipe does not pass through the center of the main cleaning pipe, the force of the injected cleaning water rotates the filter loosely fitted in the main cleaning pipe with respect to the main cleaning pipe Acts as a force to cause For this reason, the filter rotates with respect to the main cleaning pipe. At this time, in order to act as the largest rotational force, it is preferable that the cleaning water is jetted in a direction perpendicular to the radial direction of the filter, that is, a tangential direction. Therefore, the injection direction of the cleaning water injection hole of the sub-cleaning pipe is set to a direction parallel to the tangential direction of the main cleaning pipe, and a large rotational force is applied to the filter loosely fitted to the main cleaning pipe. In addition, it is preferable to make the washing | cleaning water injected from the washing water injection hole of a sub washing pipe collide with the outer peripheral side of a filter as much as possible.

また、請求項４の発明に係る円筒型フィルタの洗浄装置は、前記副洗浄管の洗浄水噴射孔の洗浄水噴射方向が鉛直下向きであることを特徴としている。   The cylindrical filter cleaning device according to the invention of claim 4 is characterized in that the cleaning water injection direction of the cleaning water injection hole of the sub-cleaning pipe is vertically downward.

副洗浄管の洗浄水噴射孔から噴射される洗浄水は、フィルタに回転力を付与し、フィルタの外周面まで押し出された固形物を飛散させることができれば、いずれの方向に向かうものであっても構わないが、鉛直下向き方向に噴射させるようにしたものである。鉛直下向きとすることにより、噴射された洗浄水の直進性を確保でき、フィルタの外周面に押し出された固形物を確実に除去できることになる。   The cleaning water sprayed from the cleaning water injection hole of the sub-cleaning pipe is directed in any direction as long as it can apply rotational force to the filter and scatter the solid matter pushed out to the outer peripheral surface of the filter. It does not matter, but the fuel is jetted in the vertically downward direction. By setting it vertically downward, the straightness of the jetted washing water can be ensured, and the solid matter pushed out to the outer peripheral surface of the filter can be surely removed.

この発明に係る円筒型フィルタの洗浄装置によれば、主洗浄管に遊嵌させたフィルタは副洗浄管の洗浄水噴射孔から噴射される洗浄水で主洗浄管を軸として回転し、主洗浄管の洗浄水噴射孔から噴射された洗浄水によって外周面に押し出されたフィルタの目詰まりの原因となっている固形物が吹き飛ばされて除去される。すなわち、透孔で形成された多数の洗浄水噴射孔を備えた管体による、主洗浄管と副洗浄管の２本の洗浄管からなる構造であるから、簡単な構造であり、フィルタを確実に回転させて洗浄位置を順次変更させることができる。   According to the cylindrical filter cleaning device of the present invention, the filter loosely fitted in the main cleaning pipe rotates around the main cleaning pipe with the cleaning water sprayed from the cleaning water injection hole of the sub cleaning pipe, and the main cleaning pipe The solid matter causing the clogging of the filter pushed out to the outer peripheral surface by the cleaning water sprayed from the cleaning water spray hole of the pipe is blown off and removed. That is, since the structure is composed of two cleaning pipes, a main cleaning pipe and a sub-cleaning pipe, with a tube body having a large number of cleaning water injection holes formed by through-holes, the structure is simple and the filter is surely secured. The cleaning position can be changed in sequence by rotating the

また、請求項２の発明に係る円筒型フィルタの洗浄装置によれば、フィルタを主洗浄管に対して浮遊した状態とすることができるので、フィルタの主洗浄管に対する回転を円滑に行うことができる。   According to the cylindrical filter cleaning apparatus of the second aspect of the present invention, the filter can be floated with respect to the main cleaning pipe, so that the filter can be smoothly rotated with respect to the main cleaning pipe. it can.

また、請求項３の発明に係る円筒型フィルタの洗浄装置によれば、副洗浄管の洗浄水噴射孔から噴射された洗浄水によりフィルタを確実に、しかも効率よく回転させることができる。   According to the cylindrical filter cleaning device of the third aspect of the present invention, the filter can be reliably and efficiently rotated by the cleaning water sprayed from the cleaning water spray hole of the sub cleaning pipe.

また、請求項４の発明に係る円筒型フィルタの洗浄装置によれば、副洗浄管の洗浄水噴射孔から噴射された洗浄水は確実に直進してフィルタに衝突するから、フィルタを回転させるために、最も効率よく回転力を付与することができる。   According to the cylindrical filter cleaning device of the invention of claim 4, the cleaning water sprayed from the cleaning water injection hole of the sub cleaning pipe surely goes straight and collides with the filter, so that the filter is rotated. The rotational force can be applied most efficiently.

以下、図示した好ましい実施の形態に基づいて、この発明に係る円筒型フィルタの洗浄装置を具体的に説明する。   Hereinafter, based on a preferred embodiment shown in the drawings, a cylindrical filter cleaning device according to the present invention will be described in detail.

図１はこの発明に係る洗浄装置１の構造を説明する概略の斜視図であり、洗浄水を流通させる幹洗浄管２に主洗浄管３と副洗浄管４とを接続した構造とされている。図２は目詰まりを解消するためにこの洗浄装置１により洗浄されるフィルタ５の一例を示すもので、洗浄されるべきフィルタ５は円筒型をしたものであり、その壁体に被処理流体を流通させることにより被処理流体に含まれた固形物を捕捉して、被処理流体から固形物を除去するものである。このため、捕捉された固形物が堆積して目詰まりが生じるので、洗浄装置１に供してこの目詰まりを解消すべく洗浄することになる。なお、この洗浄装置１に供することができるフィルタ５としては、円筒型の壁体に被処理流体を流通することによるものであれば、いかなる材質のものであっても、またフィルタ５の構造がどのようなものでっても構わない。そして、前記主洗浄管３と副洗浄管４、特に主洗浄管３には、このフィルタ５を遊嵌できる外径の管体が用いられている。また、これら洗浄管３、４の長さは、洗浄すべきフィルタ５の長さよりも大きいものとしてある。   FIG. 1 is a schematic perspective view for explaining the structure of a cleaning apparatus 1 according to the present invention, in which a main cleaning pipe 3 and a sub-cleaning pipe 4 are connected to a main cleaning pipe 2 through which cleaning water flows. . FIG. 2 shows an example of a filter 5 that is cleaned by the cleaning device 1 in order to eliminate clogging. The filter 5 to be cleaned has a cylindrical shape, and a fluid to be treated is placed on its wall. By circulating, the solid matter contained in the fluid to be treated is captured, and the solid matter is removed from the fluid to be treated. For this reason, since the trapped solid matter is accumulated and clogging occurs, cleaning is performed to eliminate this clogging by using the cleaning device 1. The filter 5 that can be used in the cleaning device 1 may be made of any material as long as the fluid to be processed is circulated through the cylindrical wall body. It doesn't matter what it is. The main cleaning pipe 3 and the sub-cleaning pipe 4, particularly the main cleaning pipe 3, use an outer diameter tubular body into which the filter 5 can be loosely fitted. The lengths of the cleaning tubes 3 and 4 are longer than the length of the filter 5 to be cleaned.

前記洗浄管３、４のそれぞれには、図１に示すように、洗浄水W3、W4を噴射するための洗浄水噴射孔としてのノズル3a、4aがこれら洗浄管３、４の長手方向に配設されている。主洗浄管３のノズル3aは、該ノズル3aから噴射される洗浄水W3が鉛直上向きとなるようにしてあり、副洗浄管４のノズル4aは、該ノズル4aから噴射される洗浄水W4が鉛直下向きとなるようにしてある。また、図３に示すように、副洗浄管４のノズル4aから噴射された洗浄水W4は主洗浄管３の中心軸を通過することなく、主洗浄管３に遊嵌されたフィルタ５の外周面と交差するようにしてある。すなわち、副洗浄管４からの洗浄水W4は主洗浄管３に遊嵌されたフィルタ５に衝突させるようにしてある。しかも、フィルタ５における洗浄水W4の衝突位置は、外周面における接触線を鉛直線とした場合の接触位置に極力近い位置としてある。 As shown in FIG. 1, nozzles 3 a and 4 a as cleaning water injection holes for injecting cleaning water W 3 and W 4 are provided in the cleaning pipes 3 and 4, respectively, in the longitudinal direction of the cleaning pipes 3 and 4. It is arranged. Nozzle 3a of the main wash tube 3, Yes cleaning water W 3 ejected from the nozzle 3a is made to be vertically upward, the nozzle 4a of the sub-cleaning tube 4, the cleaning water W 4 ejected from the nozzles 4a Is vertically downward. In addition, as shown in FIG. 3, the cleaning water W 4 sprayed from the nozzle 4 a of the sub cleaning pipe 4 does not pass through the central axis of the main cleaning pipe 3, and the filter 5 fitted loosely in the main cleaning pipe 3. It intersects with the outer peripheral surface. That is, the cleaning water W 4 from the secondary cleaning tube 4 are so as to collide with the filter 5 which is loosely fitted in the main wash tube 3. Moreover, the collision position of the cleaning water W 4 in the filter 5 is a position as close as possible to the contact position in the case of a vertical line of the contact line on the outer circumferential surface.

また、図１及び図４に示すように、主洗浄管３には主洗浄弁６が、副洗浄管４には副洗浄弁７が、それぞれ設けられており、これらを開放することによりノズル3a、4aから前記幹洗浄管２を通って供給される洗浄水が噴射される。なお、これら主洗浄弁６と副洗浄弁７とに、例えば電磁弁を用いてそのアクチュエータをタイマー作動させることにより、一定時間これら主洗浄弁６と副洗浄弁７とを開放させるようにすることもできる。   As shown in FIGS. 1 and 4, the main cleaning pipe 3 is provided with a main cleaning valve 6, and the sub cleaning pipe 4 is provided with a sub cleaning valve 7. By opening these, the nozzle 3 a is opened. , 4a, the washing water supplied through the trunk washing pipe 2 is jetted. It is to be noted that the main cleaning valve 6 and the sub cleaning valve 7 are opened for a certain period of time by, for example, using an electromagnetic valve to operate the actuator of the main cleaning valve 6 and the sub cleaning valve 7 with a timer. You can also.

以上により構成されたこの発明に係る円筒型フィルタの洗浄装置の作用を、以下に説明する。   The operation of the cylindrical filter cleaning device according to the present invention configured as described above will be described below.

フィルタ５は、被処理流体の流路に設置された図示しないストレーナに装着されて、被処理流体をフィルタ５の外周側から内周側に通過させて被処理流体中に固形分を捕捉して除去する。このため、長時間の使用により目詰まりが生じることになる。目詰まりが生じたフィルタ５をストレーナから取り外して、図３及び図４に示すように、前記主洗浄管３に遊嵌させて保持させる。次いで、前記主洗浄弁６と副洗浄弁７とを開放して洗浄水を主洗浄管３と副洗浄管４に導入させる。これにより、主洗浄管３のノズル3aと副洗浄管４のノズル4aとのそれぞれから洗浄水が噴射される。   The filter 5 is attached to a strainer (not shown) installed in the flow path of the fluid to be processed, and passes the fluid to be processed from the outer peripheral side to the inner peripheral side of the filter 5 to capture the solid content in the fluid to be processed. Remove. For this reason, clogging occurs due to long-term use. The clogged filter 5 is removed from the strainer, and is loosely fitted to the main cleaning pipe 3 and held as shown in FIGS. Next, the main washing valve 6 and the sub washing valve 7 are opened, and washing water is introduced into the main washing pipe 3 and the sub washing pipe 4. As a result, cleaning water is jetted from each of the nozzle 3a of the main cleaning pipe 3 and the nozzle 4a of the sub cleaning pipe 4.

主洗浄管３のノズル3aからは洗浄水W3が鉛直方向上向きに噴射され、該主洗浄管３に遊嵌されたフィルタ５の内周面に衝突する。この洗浄水W3の衝突の勢いにより、フィルタ５は主洗浄管３から浮き上がって浮遊した状態となる。 The cleaning water W 3 is jetted upward in the vertical direction from the nozzle 3 a of the main cleaning pipe 3 and collides with the inner peripheral surface of the filter 5 loosely fitted in the main cleaning pipe 3. Due to the impact of the washing water W 3 , the filter 5 is lifted from the main washing pipe 3 and floated.

一方、副洗浄管４のノズル4aからは、洗浄水W4が鉛直方向下向きに噴射されて主洗浄管３に遊嵌されたフィルタ５の外周面に衝突する。しかも、この洗浄水W4はフィルタ５の中心軸から偏倚した位置に衝突するから、フィルタ５は回転力を受けることになって、主洗浄管３を軸として回転することになる。この回転により、主洗浄管３のノズル3aから噴射された洗浄水W3のフィルタ５の内周面に対する衝突位置が変更されて、フィルタ５の全域にわたって洗浄水W3が衝突することになる。洗浄水W3の衝突により、フィルタ５に捕捉された固形分がフィルタ５の外周面に押し出されることになり、押し出された固形分は副洗浄管４のノズル4aから噴射された洗浄水W4により吹き飛ばされて、フィルタ５の外周面から除去される。これにより、フィルタ５は洗浄されて目詰まりが解消される。洗浄が完了したならば、主洗浄弁６と副洗浄弁７とを閉止させてフィルタ５を主洗浄管３から抜去し、図示しないストレーナに再度装着すればよい。 On the other hand, the cleaning water W 4 is jetted vertically downward from the nozzle 4 a of the sub cleaning pipe 4 and collides with the outer peripheral surface of the filter 5 that is loosely fitted to the main cleaning pipe 3. Moreover, since the cleaning water W 4 collides with a position deviated from the central axis of the filter 5, the filter 5 receives a rotational force and rotates around the main cleaning pipe 3. By this rotation, the collision position of the cleaning water W 3 sprayed from the nozzle 3 a of the main cleaning pipe 3 with respect to the inner peripheral surface of the filter 5 is changed, and the cleaning water W 3 collides over the entire area of the filter 5. Due to the collision of the washing water W 3 , the solid content captured by the filter 5 is pushed out to the outer peripheral surface of the filter 5, and the pushed solid content is washed water W 4 sprayed from the nozzle 4 a of the sub washing pipe 4. And is removed from the outer peripheral surface of the filter 5. Thereby, the filter 5 is washed and clogging is eliminated. When the cleaning is completed, the main cleaning valve 6 and the sub-cleaning valve 7 are closed, the filter 5 is removed from the main cleaning pipe 3, and is attached to a strainer (not shown).

以上に説明した実施形態では、主洗浄管３からの洗浄水W3を鉛直方向上方に向けて、副洗浄管４からの洗浄水W4を鉛直方向下方に向けて、それぞれ噴射させるようにした構造について説明したが、洗浄水W3、W4の噴射方向はこれらの方向に制限されるものではない。例えば、副洗浄管４からの洗浄水W4を水平方向に噴射するようにしても構わない。すなわち、副洗浄管４のノズル4aからの洗浄水W4の勢いを受けてフィルタ５が回転するようにすればよく、副洗浄管４のノズル4aから噴射された洗浄水W4の方向は、フィルタ５の中心軸から偏倚した位置で外周面に衝突するようにすればよい。特に、フィルタ５の接線方向と平行な方向として該接線に極力近い位置でフィルタ５に衝突させれば、フィルタ５に付与する回転力が最大となり、フィルタ５を円滑に回転させることができる。なお、本実施形態のように、鉛直方向下向きとしてあれば、洗浄水W4を確実に直進させてフィルタ５に衝突させることができて好ましい。さらに、主洗浄管３のノズル3aから噴射される洗浄水W3の方向もいずれの方向であっても構わないが、鉛直方向上向きとすることにより、フィルタ５を主洗浄管３から浮かせることが容易であり、浮遊したフィルタ５を副洗浄管４からの洗浄水W4により確実に回転させることができる。 In the embodiment described above, toward the cleaning water W 3 from the main washing pipe 3 vertically upward, toward the cleaning water W 4 from the secondary cleaning tube 4 downward in the vertical direction, and so as to respectively jet Although the structure has been described, the injection directions of the cleaning waters W 3 and W 4 are not limited to these directions. For example, it may be configured to inject cleaning water W 4 from the secondary cleaning tube 4 in the horizontal direction. That is, the filter 5 may be rotated by receiving the momentum of the cleaning water W 4 from the nozzle 4a of the sub-cleaning pipe 4, and the direction of the cleaning water W 4 sprayed from the nozzle 4a of the sub-cleaning pipe 4 is What is necessary is just to make it collide with an outer peripheral surface in the position biased from the center axis | shaft of the filter 5. FIG. In particular, if the filter 5 collides with the filter 5 at a position as close as possible to the tangential direction as a direction parallel to the tangential direction of the filter 5, the rotational force applied to the filter 5 is maximized, and the filter 5 can be smoothly rotated. Note that, as in the present embodiment, a downward downward direction is preferable because the cleaning water W 4 can surely advance straight and collide with the filter 5. Furthermore, the direction of the cleaning water W 3 sprayed from the nozzle 3a of the main cleaning pipe 3 may be any direction, but the filter 5 can be floated from the main cleaning pipe 3 by making it upward in the vertical direction. It is easy and the floated filter 5 can be reliably rotated by the washing water W 4 from the sub washing pipe 4.

さらに、主洗浄弁６と副洗浄弁７とに電磁弁を用いて、これら電磁弁のアクチュエータをタイマーにより作動させることにより、フィルタ５の洗浄を所定時間で行わせるようにすることも好ましい。   Furthermore, it is also preferable to use a solenoid valve for the main washing valve 6 and the sub washing valve 7 and operate the actuators of these solenoid valves with a timer so that the filter 5 is washed in a predetermined time.

この発明に係る円筒型フィルタの洗浄装置によれば、ストレーナから取り出したフィルタを一対の洗浄管のうちの一方に遊嵌して洗浄水を噴射することにより洗浄して確実に目詰まりを解消できるから、フィルタの洗浄作業の簡素化と洗浄時間の短縮化に寄与することができる。   According to the cylindrical filter cleaning device of the present invention, the filter taken out from the strainer can be loosely fitted to one of the pair of cleaning pipes and cleaned by spraying the cleaning water to reliably eliminate clogging. Therefore, it is possible to contribute to simplification of the filter cleaning operation and shortening of the cleaning time.
