Description

【0001】
【産業上の利用分野】
本発明は、洗浄水自動供給スクリーンに関するものであり、特に、下水等の汚水中の夾雑物を除去する自動スクリーンにおいて、自動スクリーンにより掻き上げられた「屎渣」に含まれる汚泥・汚物分を処理する屎渣処理装置に必要とされる洗浄水を自動的に供給することのできるようにした洗浄水自動供給スクリーンに係るものである。
【0002】
【従来技術】
従来、汚水流路中に、汚水は通過させ汚水中の夾雑物は斜め上方に掻き揚げて除去する自動スクリーンを設け、自動スクリーンの終端に掻き上げられた屎渣に含まれる汚泥・汚物分(以下、汚物という)の脱水処理をする屎渣処理装置の上端を接続した構成は、公知である。
また、屎渣処理装置に処理を促進させるために処理用水を供給するようにしたものも公知である。
即ち、自動スクリーンの櫛歯により掻き上げられる屎渣には、ある程度水溶性の高い汚泥・汚物が含まれることは避けられず、これを衛生的に処理・処分するには十分に洗浄して水に溶ける物は溶解させてから処理すると、処理効率が向上するのである。
【0003】
【発明が解決しようとする課題】
前記公知例では、水溶性の汚物分を除去するのに、水道水や井戸水あるいは下水処理水を使用するので、何れの水も調達コストが掛かり、しかも、屎渣処理装置に供給するための配管設備が必要となって、相当にコストが高くなるという課題がある。
しかし、工夫すると、殆どコストを掛けずに屎渣処理装置に処理用水を供給できるようになり、本願は屎渣処理装置に処理用水を供給する機能を有する洗浄水自動供給スクリーンを提供するものである。
【0004】
【発明の目的】
屎渣処理装置に対する処理用水の供給自動化、低コスト化。
【0005】
【課題を解決するための手段】
よって、本発明は、汚水は通過させて汚水と夾雑物とを分離する所定目巾に複数並設したスクリーンバー3と、該スクリーンバー3に付着した夾雑物を下から上に掻き上げ移動して除去する櫛歯5とを有し、流水路またはタンク2内に後側に至るに従い高くなるように傾斜させて設けた自動スクリーン1において、前記櫛歯5は左右一対の側部フレーム6に設けた無端チエン11に前記スクリーンバー3より外側に向かって突出するように設け、前記無端チエン11の内側には無端チエン11の回転上昇時に上側が流入口28に開口した汲み上げ体27を設け、該汲み上げ体27は無端チエン11が戻り側から掻き上げ側に反転するところで前記スクリーンバー3を通過した水を汲み上げ、前記スクリーンバー3の上部で反転する際に屎渣が排出される方向と同じ方向に汲みあげた水を放出するように構成した洗浄水自動供給スクリーンとしたものである。
【0006】
【実施例】
本発明の実施例を図面により説明すると、1は流水路またはタンク2内に設けた自動スクリーンであり、水と夾雑物とを分離するものである。自動スクリーン1の構成は任意であるが、少なくとも、水は通過させるが夾雑物は通過させずに捕捉する所定目巾に複数並設したスクリーンバー3により構成するスクリーン部4と、前記スクリーンバー3の間を下から上に移動してスクリーンバー3に捕捉された夾雑物を掻き上げて除去する櫛歯5を有していればよい。
【0007】
一例を示すと、流水路に45度〜60度に後側に至るに従い高くなるように傾斜させた左右一対の側部フレーム6を設け、該側部フレーム6は左右に所定間隔おいて位置させ、各側部フレーム6には駆動軸7と受動軸8とを上下に軸装し、前記駆動軸7には左右一対の駆動歯車9を前記受動軸8には左右一対の受動歯車10を夫々固定し、左右の駆動歯車9と受動歯車10には無端チエン11を夫々掛け回す。左右の無端チエン11には左右方向のアタッチメント12を所定間隔をおいて複数取付け、各アタッチメント12にはスクリーンバー3より外側(前側)に向かって突出するように前記櫛歯5の基部を固定する。13はモータである。
【0008】
前記櫛歯5の前側にはスクリーン部4のスクリーンバー3を位置させ、スクリーンバー3は任意の手段により前記側部フレーム6に取付け、隣接するスクリーンバー3の間の隙間14より前記各櫛歯5の先端を前側に突出させ、櫛歯5は突出した状態で下から上に移動し、スクリーンバー3に捕捉された夾雑物を掻き上げるように構成する。15はアタッチメント12に設けた受体であり、スクリーンバー3の内側(裏側)面に摺接して無端チエン11の移動を案内する。16は無端チエン11の案内レールである。
【0009】
前記スクリーンバー3の上部は、前記駆動軸7の上方で逆U型形状に屈曲させて反転案内部20に形成し、反転案内部20は前記櫛歯5の移動軌跡に対して徐々に外側に位置するように配置することにより、櫛歯5は反転案内部20の終点で反転案内部20より屎渣を残して引っ込んで、櫛歯5が屎渣が付着しまま下降するのを防止している。
【0010】
前記反転案内部20の下方には掻き上げられた屎渣に含まれる汚物を脱水処理する屎渣処理装置21のホッパー22を位置させる。ホッパー22の下方には一対のスクリュウ23を設けた脱水部24に形成し、脱水部24は一方が高く他方を低く傾斜させ、脱水部24の高い側には屎渣排出部を形成し、低い側の脱水部24は排水管25に接続する。
【0011】
しかして、前記無端チエン11の回転方向の内側には所定間隔をおいて汚水を汲み上げる汲み上げ体27を複数設ける。汲み上げ体27は無端チエン11の回転上昇時において上側を流入口28に開口した箱体29に形成し、箱体29の左右両側を櫛歯5と反対側面の前記アタッチメント12に取付ける。汲み上げ体27は、無端チエン11の内側を無端チエン11と共に移動し、無端チエン11が戻り側から掻き上げ側に反転するところで前記スクリーン部4を通過した水を汲み上げ、前記反転案内部20で反転する際に屎渣が排出される方向と同じ方向に汲みあげた水を放出する。
【0012】
したがって、汲み上げ体27は無端チエン11の回転方向の内周側に設けられるので、上昇側の無端チエン11と下降側の無端チエン11の間であって、自動スクリーン1の上下2か所の駆動歯車9と受動歯車10の部分で反転するのに支障がない大きさ(深さ)を有するように構成する。
【0013】
この場合、汲み上げ体27は、アタッチメント12に着脱自在に取付けると、掻き上げられた屎渣の性状と量に対して必要十分な水量を汲み上げるために、その容量と数とを調整することが容易にでき、好適である。
また、汲み上げ体27は、櫛歯5の手前側に、櫛歯5が反転案内部20で反転中に水を放出するように設けると(図1、図8)、櫛歯5の洗浄を効率的に行えて、好適である。
【0014】
なお、実施例では、自動スクリーン1の終端に屎渣処理装置21を設け、屎渣処理装置21はホッパー22と脱水部24を有しているが、屎渣籠やコンベヤーあるいは流水トラフなどを設けてもよく、これらに汲み上げ体27から必要とされる洗浄水を供給してもよい。
図中、30は排水口、31は自動スクリーン1の上部に設けた屎渣の落下を誘導する誘導樋兼カバー、32は下水管である。
【0015】
【作用】
次に作用を述べる。
流水路またはタンク2に流入した下水のうち水は、スクリーン部4のスクリーンバー3の間の隙間14を通過し、自動スクリーン1の排水口30から排水され、下水のうち夾雑物はスクリーン部4を通過せずにスクリーン部4の前面に付着したように捕捉される。
【0016】
この状態で、駆動軸7をモータにより回転させると、無端チエン11が回転し、無端チエン11に取付けられているアタッチメント12が前記スクリーンバー3の背面側で下から上に移動する。
【0017】
アタッチメント12には櫛歯5の基部を固定し、櫛歯5の先端はスクリーンバー3より外側(前側)に向かって突出しているから、スクリーン部4の前面に付着したように捕捉された夾雑物は櫛歯5により掻き上げられ、反転案内部20で反転して下方の屎渣処理装置21のホッパー22内に落下し、次いで脱水部24により脱水されて処理される。
【0018】
この場合、自動スクリーン1の櫛歯5により掻き上げられる屎渣には、ある程度水溶性の高い汚泥・汚物が含まれることは避けられず、これを衛生的に処理・処分するには十分に洗浄して水に溶ける物は溶解させてから処理すると、処理効率が向上し、このため、屎渣処理装置21の処理に際して洗浄水が必須であるが、この洗浄水の供給に従来は相当にコストが掛かっていた。
【0019】
本願では、無端チエン11の回転方向の内側に所定間隔をおいて汚水を汲み上げうる汲み上げ体27を複数設けているから、汲み上げ体27は無端チエン11が戻り側から掻き上げ側に反転するところでスクリーン部4を通過した水を汲み上げ、反転案内部20で反転する際に屎渣が排出される方向と同じ方向に汲みあげた水を放出し、汲みあげた水は屎渣処理装置21の処理用水として供給される。
【0020】
即ち、流水路またはタンク2内に後側に至るに従い高くなるように傾斜させてスクリーン部4を設けているので、反転案内部20の下方に屎渣処理装置21を位置させれば、屎渣と汲みあげた処理用水は屎渣が排出される方向と同じ方向に放出されて屎渣処理装置21に供給でき、合理的な構成となる。
【0021】
したがって、水道水や、汚水処理後の処理水を別の動力と配管設備及び自動運転電気操作回路を用いて供給することなく、自動スクリーン1の櫛歯5を作動させる同一駆動源により処理用水を屎渣処理装置21に供給する。
【0022】
しかも、自動スクリーン1の櫛歯5による屎渣の掻き上げと同期して洗浄水の供給が自動的に開始され、掻き上げが停止すると停止し、一々操作する必要がなく、自動スクリーン1の櫛歯5の作動を制御する制御機構をそのまま利用でき、制御も簡素にできる。
【0023】
前記の場合、汲み上げ体27はスクリーンバー3の後側で反転して水を汲み上げるから、用途に応じて必要な目巾でスクリーンニングされた汚水であり、屎渣処理装置21に供給された汚泥・汚物分を洗い流すのには十分な効力を発揮する。
【0024】
また、汲み上げ体27はスクリーン部4の上部で反転するときに、汲み上げ体27ないの水を重力落下させるから、汲み上げられて放出される水は、スクリーン部4のスクリーンバー3の上端付近の屎渣の払い落としや、櫛歯5の洗浄の効果も期待でき、自動スクリーン1の洗浄にも作用する。
【0025】
また、汲み上げ体27は無端チエン11の回転方向の内周側に設けられるので、上昇側の無端チエン11と下降側の無端チエン11の間であって、自動スクリーン1の上下2か所の駆動歯車9と受動歯車10の部分で反転するのに支障がない大きさ(深さ)を有するように構成しているから、自動スクリーン1内に内蔵されることになり、運搬、設置、管理等を容易にする。
【0026】
【効果】
本発明は、汚水は通過させて汚水と夾雑物とを分離する所定目巾に複数並設したスクリーンバー3と、該スクリーンバー3に付着した夾雑物を下から上に掻き上げ移動して除去する櫛歯5とを有し、流水路またはタンク2内に後側に至るに従い高くなるように傾斜させて設けた自動スクリーン1において、前記櫛歯5は左右一対の側部フレーム6に設けた無端チエン11に前記スクリーンバー3より外側に向かって突出するように設け、前記無端チエン11の内側には無端チエン11の回転上昇時に上側が流入口28に開口した汲み上げ体27を設け、該汲み上げ体27は無端チエン11が戻り側から掻き上げ側に反転するところで前記スクリーンバー3を通過した水を汲み上げ、前記スクリーンバー3の上部で反転する際に屎渣が排出される方向と同じ方向に汲みあげた水を放出するように構成した洗浄水自動供給スクリーンとしたものであるから、自動スクリーン1によりこれの下手側に配置した処理装置に十分な処理用水を供給でき、しかも、自動スクリーン1の動力を利用するので、別の動力と配管設備及び自動運転電気操作回路等が不要になって、殆どコストを掛けずに処理用水の供給を実現でき、また、自動スクリーン1通過後の汚水でありながら、用途に応じて必要な目巾でスクリーンニングされたものであるので掻き上げられた汚泥・汚物分を洗い流すのに十分な効力を有し、汚水の有効利用が図れ、また、汲み上げ体の容量と数を調整することにより、供給量の調節も容易になり、また、汲み上げ体27により汲み上げて放出される水は、自動スクリーン1の自体の屎渣の払いおとしや櫛歯の洗浄の作用も期待できるという効果を奏する。

[0002]
[Prior art]
2. Description of the Related Art Conventionally, an automatic screen has been provided in a sewage passage for passing sewage and removing dirt and impurities in the sewage by diagonally lifting the sludge upward. A configuration in which the upper end of a sewage treatment apparatus for performing dehydration treatment of waste is connected is known.
Further, there is also known a system in which treatment water is supplied to a sewage treatment apparatus to promote the treatment.
That is, it is inevitable that the sewage scraped up by the comb teeth of the automatic screen contains sludge and filth which are highly water-soluble to some extent. If the material that dissolves in is dissolved and then treated, the treatment efficiency is improved.
[0003]
[Problems to be solved by the invention]
In the known example, since tap water, well water, or sewage treatment water is used to remove water-soluble dirt, any water is procured at a high cost, and furthermore, piping for supplying the wastewater treatment device is provided. There is a problem that equipment is required and the cost is considerably increased.
However, if devised, it becomes possible to supply treatment water to the sewage treatment apparatus at almost no cost, and the present application provides a washing water automatic supply screen having a function of supplying treatment water to the sewage treatment apparatus. is there.
[0004]

[0005]
[Means for Solving the Problems]
Accordingly, the present invention provides a screen bar 3 having a plurality of juxtaposed lines arranged at a predetermined interval for separating sewage and contaminants by allowing sewage to pass therethrough, and moving the contaminants attached to the screen bar 3 upward from below. In the automatic screen 1 having the comb teeth 5 to be removed by being removed so as to become higher in the running water channel or the tank 2 toward the rear side, the comb teeth 5 are attached to the pair of left and right side frames 6. The endless chain 11 provided is provided so as to protrude outward from the screen bar 3, and a pumping body 27 whose upper side is opened to the inflow port 28 when the endless chain 11 rotates upward is provided inside the endless chain 11, The pumping body 27 pumps up the water that has passed through the screen bar 3 when the endless chain 11 reverses from the return side to the scraping side. The water pumped in the same direction as the direction issued is obtained by the washing water autofeed screen configured to emit.
[0006]
【Example】
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes an automatic screen provided in a flowing water channel or a tank 2 for separating water and impurities. The configuration of the automatic screen 1 is arbitrary, but at least a screen section 4 composed of a plurality of screen bars 3 arranged in a predetermined eye width to capture water but not contaminants, and the screen bar 3 It suffices to have the comb teeth 5 that move upward from below to lift up and remove impurities trapped on the screen bar 3.
[0007]
As an example, a pair of left and right side frames 6 that are inclined so as to become higher toward the rear side at 45 degrees to 60 degrees in the flowing water channel are provided, and the side frames 6 are positioned at predetermined intervals on the left and right. A drive shaft 7 and a passive shaft 8 are vertically mounted on each side frame 6, and a pair of left and right drive gears 9 are mounted on the drive shaft 7 and a pair of left and right passive gears 10 are mounted on the passive shaft 8, respectively. The endless chain 11 is wrapped around the drive gear 9 and the passive gear 10 on the left and right, respectively. A plurality of attachments 12 in the left-right direction are attached to the left and right endless chains 11 at predetermined intervals, and the base of the comb teeth 5 is fixed to each attachment 12 so as to protrude outward (frontward) from the screen bar 3. . 13 is a motor.
[0008]
The screen bar 3 of the screen portion 4 is positioned in front of the comb teeth 5, and the screen bar 3 is attached to the side frame 6 by any means. 5 is configured to protrude forward, and the comb teeth 5 are moved upward from the bottom in a protruding state to scrape up foreign substances captured by the screen bar 3. Reference numeral 15 denotes a receiver provided on the attachment 12, which slides on the inner (back side) surface of the screen bar 3 to guide the movement of the endless chain 11. Reference numeral 16 denotes a guide rail of the endless chain 11.
[0009]
The upper portion of the screen bar 3 is bent into an inverted U shape above the drive shaft 7 to form a reversing guide portion 20, and the reversing guide portion 20 gradually moves outward with respect to the movement locus of the comb teeth 5. By arranging the comb teeth 5 so as to be positioned, the comb teeth 5 are retracted at the end point of the reversal guide section 20 while leaving the sewage from the reversal guide section 20 to prevent the comb teeth 5 from descending with the sewage adhered. I have.
[0010]
A hopper 22 of a sewage treatment apparatus 21 for dehydrating sewage contained in the scraped up sewage is located below the reversing guide section 20. Below the hopper 22, a pair of screws 23 is formed in a dewatering unit 24 provided with a pair of screws 23. One of the dewatering units 24 is inclined higher and the other lower, and a waste discharging unit is formed on the higher side of the dewatering unit 24. The dewatering section 24 on the side is connected to a drain pipe 25.
[0011]
Thus, a plurality of pumping bodies 27 for pumping sewage water are provided at predetermined intervals inside the endless chain 11 in the rotation direction. When the endless chain 11 rotates upward, the pumping body 27 is formed in a box 29 having an upper side opened to an inlet 28, and the left and right sides of the box 29 are attached to the attachment 12 on the side opposite to the comb teeth 5. The pumping body 27 moves inside the endless chain 11 together with the endless chain 11, and when the endless chain 11 reverses from the return side to the scraping side, pumps up the water that has passed through the screen portion 4 and reverses the water at the reverse guide portion 20. When discharging, the water that has been pumped is discharged in the same direction as the direction in which the waste is discharged.
[0012]
Therefore, since the pumping body 27 is provided on the inner circumferential side in the rotation direction of the endless chain 11, the upper and lower portions of the automatic screen 1 are driven between the endless chain 11 on the rising side and the endless chain 11 on the falling side. The gear 9 and the passive gear 10 are configured to have a size (depth) that does not hinder reversal.
[0013]
In this case, when the pumping body 27 is detachably attached to the attachment 12, it is easy to adjust the capacity and the number of pumping bodies 27 in order to pump up a necessary and sufficient amount of water with respect to the properties and amount of the scraped up sewage. And is suitable.
Further, when the pumping body 27 is provided on the front side of the comb teeth 5 so that the comb teeth 5 discharge water while being inverted by the inversion guide portion 20 (FIGS. 1 and 8), the cleaning of the comb teeth 5 is efficient. It is suitable and can be performed.
[0014]
In the embodiment, a waste disposal apparatus 21 is provided at the end of the automatic screen 1, and the waste disposal apparatus 21 has a hopper 22 and a dewatering unit 24. However, a waste basket, a conveyor, a running water trough, and the like are provided. Cleaning water may be supplied from the pumping body 27 to these.
In the drawing, reference numeral 30 denotes a drain port, 31 denotes a gutter / cover provided on the upper portion of the automatic screen 1 for guiding sewage, and 32 denotes a sewer pipe.
[0015]
[Action]
Next, the operation will be described.
Among the sewage flowing into the flowing water channel or the tank 2, water passes through the gap 14 between the screen bars 3 of the screen unit 4 and is drained from the drainage port 30 of the automatic screen 1. Is captured as if it had adhered to the front surface of the screen unit 4 without passing through.
[0016]
In this state, when the drive shaft 7 is rotated by the motor, the endless chain 11 rotates, and the attachment 12 attached to the endless chain 11 moves upward from below on the back side of the screen bar 3.
[0017]
The base of the comb teeth 5 is fixed to the attachment 12, and the tips of the comb teeth 5 project outward (frontward) from the screen bar 3. Is scraped up by the comb teeth 5, inverted by the inversion guide section 20, falls into the hopper 22 of the waste disposal apparatus 21 below, and then dehydrated and processed by the dehydration section 24.
[0018]
In this case, it is inevitable that the sewage scraped up by the comb teeth 5 of the automatic screen 1 contains sludge and filth which are highly water-soluble to some extent. If the water-soluble matter is dissolved and then treated, the treatment efficiency is improved. Therefore, washing water is indispensable for the treatment of the sewage treatment apparatus 21, but the supply of the washing water has conventionally required a considerable cost. Was hanging.
[0019]
In the present application, since a plurality of pumping bodies 27 capable of pumping sewage water are provided at predetermined intervals inside the rotation direction of the endless chain 11, the pumping body 27 is a screen where the endless chain 11 reverses from the return side to the scraping side. The water that has passed through the section 4 is pumped up, and the water that has been pumped in the same direction as the waste is discharged when the water is inverted by the inversion guide section 20 is discharged. Supplied as
[0020]
That is, since the screen portion 4 is provided so as to be inclined higher toward the rear side in the flowing water channel or the tank 2, if the waste disposal device 21 is positioned below the reverse guide portion 20, the waste The processing water thus pumped out is discharged in the same direction as the direction in which the sewage is discharged, and can be supplied to the sewage treatment apparatus 21, resulting in a rational configuration.
[0021]
Therefore, the treatment water is supplied by the same drive source that operates the comb teeth 5 of the automatic screen 1 without supplying tap water or treated water after sewage treatment using another power and piping equipment and an automatic operation electric operation circuit. It is supplied to the waste disposal device 21.
[0022]
In addition, the supply of the washing water is automatically started in synchronization with the scraping of the sewage by the comb teeth 5 of the automatic screen 1 and stopped when the scraping is stopped. The control mechanism for controlling the operation of the teeth 5 can be used as it is, and the control can be simplified.
[0023]
In the above case, the pumping body 27 is turned upside down on the rear side of the screen bar 3 and pumps up water. Therefore, it is sewage screened with a required width depending on the application, and the sludge supplied to the sewage treatment apparatus 21 is used. -Effective enough to wash away dirt.
[0024]
Further, when the pumping body 27 is turned over at the upper part of the screen section 4, the water without the pumping body 27 drops by gravity, so that the water that is pumped and released is discharged from the waste near the upper end of the screen bar 3 of the screen section 4. The effect of removing residue and cleaning the comb teeth 5 can also be expected, and also works for cleaning the automatic screen 1.
[0025]
Further, since the pumping body 27 is provided on the inner peripheral side in the rotation direction of the endless chain 11, the upper and lower two portions of the automatic screen 1 are driven between the endless chain 11 on the ascending side and the endless chain 11 on the descending side. Since the gear 9 and the passive gear 10 are configured to have a size (depth) that does not hinder reversal, they are built into the automatic screen 1, and are transported, installed, managed, and the like. To facilitate.
[0026]
【effect】
According to the present invention, a plurality of screen bars 3 arranged side by side at predetermined intervals for separating sewage and contaminants by allowing sewage to pass therethrough, and removing and adhering the contaminants attached to the screen bar 3 from the bottom upward. In the automatic screen 1 which has the comb teeth 5 to be inclined and becomes higher in the running water channel or the tank 2 toward the rear side, the comb teeth 5 are provided on a pair of left and right side frames 6. The endless chain 11 is provided so as to protrude outward from the screen bar 3. Inside the endless chain 11, a pumping body 27 whose upper side is opened to an inflow port 28 when the endless chain 11 rotates upward is provided. The body 27 pumps up the water that has passed through the screen bar 3 when the endless chain 11 reverses from the return side to the scraping side, and waste is discharged when the endless chain 11 reverses above the screen bar 3. Since the cleaning water automatic supply screen is configured to discharge the water pumped in the same direction as the direction, the automatic screen 1 can supply sufficient processing water to a processing device disposed on the lower side of the screen, In addition, since the power of the automatic screen 1 is used, separate power and piping equipment and an automatic operation electric operation circuit and the like are not required, and the supply of the treatment water can be realized at almost no cost. Although it is sewage after passing, it is screened with the required width depending on the application, so it has sufficient efficacy to wash away the sludge and dirt that has been scraped up, and effective use of sewage can be achieved In addition, by adjusting the volume and number of the pumping bodies, the supply amount can be easily adjusted, and the water pumped and discharged by the pumping bodies 27 can be controlled by the automatic screen 1. Effect of cleaning the payment burnished or comb teeth of 屎渣 also an effect that can be expected.
