Description

本発明は、互いに連結可能に上下に分割した浄化槽の上槽部分と下槽部分の内側で、内部空間を複数の処理槽に仕切り、且つ前記上槽部分又は前記下槽部分の少なくともいずれか一方の対向壁間にわたって設置する仕切板を設け、前記対向壁夫々に設けた被係合凹部に各別に係合する一対の係合突起部を前記仕切板に設けて、前記一対の係合突起部を、前記被係合凹部夫々に係合させることによって、前記対向壁間の距離が開くのを防止してある浄化槽に関する。   The present invention divides the internal space into a plurality of treatment tanks inside the upper tank part and the lower tank part of the septic tank divided into upper and lower parts that can be connected to each other, and at least one of the upper tank part and the lower tank part Provided with a partition plate installed between the opposing walls, and provided with a pair of engaging projections on the partition plate, each engaging with an engaged recess provided on each of the opposing walls. It is related with the septic tank which has prevented the distance between the said opposing walls from opening by engaging with each said to-be-engaged recessed part.

通常、浄化槽には、上流側から嫌気処理槽、好気処理槽、沈殿槽、及び消毒槽等といった複数の処理槽が、仕切板を介して順に配置されている。
被処理水（し尿、生活雑排水等）は、流入口から流入し、以降、嫌気処理槽、好気処理槽において順次浄化処理された後、沈殿槽に流入し、沈殿槽に流入した被処理水は、汚泥が沈殿分離され、その上澄み液が、消毒筒内の消毒剤と接触して消毒された後、消毒槽を経て、放流口から放流される。
一般的に、浄化槽に被処理水が流入すると、その水圧によって、浄化槽全体が水平方向に膨らもうとする（即ち、浄化槽内の対向壁間の距離が開こうとする）。これを防止するために、仕切板を接着剤で固定する場合であっても仕切板をネジ等の締結部分で外槽に固定している。また、仕切板の外縁よりも外側に突出する一対の係合突起部を仕切板に設け、係合突起部が係合する被係合凹部を浄化槽に設け、仕切板を浄化槽の嵌合溝に嵌合させる際、一対の係合突起部と被係合凹部夫々とを互いに係合させて、浄化槽に被処理水が流入して浄化槽全体が水平方向に膨もうとしても、対向壁間の距離を開き難くして、浄化槽の膨み変形に伴う破損を防止した浄化槽が提案されている。（特許文献１参照） Usually, in the septic tank, a plurality of treatment tanks such as an anaerobic treatment tank, an aerobic treatment tank, a sedimentation tank, a disinfection tank, and the like are sequentially arranged from the upstream side via a partition plate.
To-be-treated water (human waste, household wastewater, etc.) flows from the inflow port, and after being sequentially purified in the anaerobic treatment tank and aerobic treatment tank, it flows into the settling tank and then into the settling tank. The water is discharged from the outlet through the sterilization tank after the sludge is precipitated and separated and the supernatant liquid is sterilized by contact with the disinfectant in the sterilization cylinder.
In general, when the water to be treated flows into the septic tank, the entire septic tank tends to swell in the horizontal direction due to the water pressure (that is, the distance between the opposing walls in the septic tank tends to open). In order to prevent this, even when the partition plate is fixed with an adhesive, the partition plate is fixed to the outer tub with a fastening portion such as a screw. In addition, a pair of engaging protrusions that protrude outward from the outer edge of the partition plate are provided on the partition plate, an engaged recess that engages with the engagement protrusion is provided in the septic tank, and the partition plate is provided in the fitting groove of the septic tank. When fitting, a pair of engaging protrusions and engaged recesses are engaged with each other so that the water to be treated flows into the septic tank and the entire septic tank swells in the horizontal direction. There has been proposed a septic tank that makes it difficult to open the septic tank and prevents breakage of the septic tank due to bulge deformation. (See Patent Document 1)

実開昭５４−１７４２５８号公報Japanese Utility Model Publication No. 54-174258

しかしながら、上記従来の浄化槽における仕切板の係合突起部は、仕切板の外縁よりも外側に突出していたため、浄化槽を組付ける等の際、何らかの衝撃が加わり易く、破損し易いものであった。また、係合突起部まわりの止水処理も複雑となり困難であった。
本発明は、上記実情に鑑みてなされたものであって、浄化槽の対向壁間の距離が開くのを防止し得る係合突起部が、破損し難く、止水処理が容易な浄化槽を提供するものである。 However, since the engaging projections of the partition plate in the conventional septic tank protrude outward from the outer edge of the partition plate, some impact is likely to be applied and easily damaged when the septic tank is assembled. In addition, the water stop treatment around the engaging protrusion is complicated and difficult.
The present invention has been made in view of the above circumstances, and provides a septic tank in which an engaging protrusion that can prevent the distance between the opposing walls of the septic tank from opening is difficult to break and a water stop treatment is easy. Is.

本発明の第１特徴構成は、互いに連結可能に上下に分割され得る浄化槽の上槽部分と下槽部分の内側で、内部空間を複数の処理槽に仕切り、且つ前記上槽部分及び前記下槽部分の対向壁間にわたって設置される仕切板を備え、前記対向壁夫々に設けた被係合凹部に各別に係合する一対の係合突起部を前記仕切板に設けて、前記一対の係合突起部を、前記被係合凹部夫々に係合させることによって、前記対向壁間の距離が開くのを防止してある浄化槽であって、前記上槽部分及び前記下槽部分に前記仕切板の周縁部分を嵌合固定する嵌合溝が設けられ、前記上槽部分と前記下槽部分の合わせ面の前記嵌合溝の開口部の側面の一方に、上下方向且つ前記仕切板の板厚方向に窪ませた前記被係合凹部を形成し、前記嵌合溝に前記仕切板の周縁部分を挿入した際に、前記上槽部分と前記下槽部分の前記被係合凹部の両方にわたって挿入可能で上下方向に延びる板状の前記係合突起部を、前記仕切板の板厚方向に突出するように前記仕切板の外縁よりも内側に一体形成してある点にある。
〔作用及び効果〕
本発明の浄化槽においては、係合突起部を、仕切板の外縁よりも内側で、その板厚方向に突出するように仕切板に一体形成してあるため、浄化槽を組付ける等の際、衝撃が加わり難く、破損し難い。
また、浄化槽に被処理水が流入して多くの水圧がかかったとしても浄化槽全体が水平に膨らんで変形するのを防止できるため仕切板と外槽部分が離間せず、しかも、仕切板外縁よりも外側に突出する部分がないので、止水処理は、接着剤等を仕切板外縁に一様に塗布するだけで良く、止水効果も高くすることができる。 The first characteristic configuration of the present invention is that the inner space is divided into a plurality of processing tanks inside the upper tank part and the lower tank part of the septic tank that can be divided into upper and lower parts so as to be connectable to each other, and the upper tank part and the lower tank comprising a partition plate that is installed over a pair countercurrent walls portions, a pair of engaging projections to be engaged with each other in the engaged concave portion provided on the facing wall respectively provided on the partition plate, the pair of engagement A septic tank that prevents the distance between the opposing walls from opening by engaging a mating protrusion with each of the engaged recesses , wherein the partition plate is provided on the upper tank part and the lower tank part. A fitting groove for fitting and fixing the peripheral portion of the upper tub portion and the lower tub portion is provided on one side surface of the opening portion of the fitting groove on the mating surface of the upper tub portion and the lower tub portion, and the thickness of the partition plate Forming the engaged recess recessed in the direction, and forming a peripheral edge portion of the partition plate in the fitting groove. When inserted, the plate-like engaging protrusions that can be inserted over both the engaged recesses of the upper tank part and the lower tank part and extend in the vertical direction protrude in the plate thickness direction of the partition plate. Thus, it is in the point integrally formed inside the outer edge of the partition plate .
[Action and effect]
In the septic tank of the present invention, the engaging protrusion is formed integrally with the partition plate so as to protrude in the thickness direction inside the outer edge of the partition plate. Is difficult to add and is difficult to break.
In addition, even if the water to be treated flows into the septic tank and a lot of water pressure is applied, the entire septic tank can be prevented from expanding and deforming horizontally, so that the partition plate and the outer tub portion are not separated from each other, and moreover from the outer edge of the partition plate. Since there is no portion protruding outward, the water-stopping treatment only needs to be applied uniformly to the outer edge of the partition plate, and the water-stopping effect can be enhanced.

また、本発明の浄化槽においては、上槽部分及び下槽部分に、被係合凹部を設けており、仕切板の係合突起部が、上槽部分の被係合凹部及び下槽部分の被係合凹部の両方にわたって係合し得るため、浄化槽に被処理水が流入して多くの水圧がかかったとしても、浄化槽全体が水平方向に膨んで変形するのを一層防止できる。 Further, in the septic tank of the present invention, the engaged recesses are provided in the upper tank part and the lower tank part, and the engaging projections of the partition plate are covered with the engaged recesses of the upper tank part and the lower tank part. Since it can be engaged over both of the engaging recesses, even if the water to be treated flows into the septic tank and a lot of water pressure is applied, it is possible to further prevent the entire septic tank from expanding and deforming in the horizontal direction.

本発明の第２特徴構成は、上下方向に延びる板状に突出形成した前記係合突起部の浄化槽内側方向の面に、前記係合突起部の上下端部から中央部に向けて浄化槽内側方向に傾斜するテーパー面が形成されている点にある。
〔作用及び効果〕
本発明の浄化槽においては、上下方向に延びる板状に突出形成した前記係合突起部の浄化槽内側方向の面に、前記係合突起部の上下端部から中央部に向けて浄化槽内側方向に傾斜するテーパー面が形成されているので、係合突起部を、被係合凹部に係合させ易い。
また、仕切板を挿入するに従い外槽と仕切板が締め付け合い、水平方向に対し位置決めされるので、仕切板のガタつきを防止することができる。 The second characteristic configuration of the present invention is a septic tank inner side direction from the upper and lower end parts of the engaging projection part toward the central part on the surface of the engaging projection part formed in a plate shape extending in the vertical direction in the septic tank inner side direction. The taper surface which inclines in the point is formed.
[Action and effect]
In the septic tank of the present invention, the surface of the engaging protrusion formed in the shape of a plate extending in the vertical direction is inclined toward the inner side of the septic tank from the upper and lower ends of the engaging protrusion toward the center. Since the taper surface which forms is formed, it is easy to engage an engaging protrusion part with a to-be-engaged recessed part.
Further, as the partition plate is inserted, the outer tub and the partition plate are tightened and positioned in the horizontal direction, so that the play of the partition plate can be prevented.

本発明の第３特徴構成は、前記係合突起部に、前記下槽部分の上端部に載置する接当部が連設されている点にある。
〔作用及び効果〕
本発明の浄化槽においては、係合突起部に、下槽部分の上端部に載置する接当部が連設されているので、浄化槽における仕切板の上下方向の位置が規定され得る。そのため、仕切板の下端と下槽部分の底面との間に、安定的に一定の隙間を確保し易くなり、例えば、その隙間に接着剤等を介在させることによって、仕切板をより強固に固定することができる。 The 3rd characteristic structure of this invention exists in the point by which the contact part mounted in the upper end part of the said lower tank part is connected with the said engaging protrusion part.
[Action and effect]
In the septic tank of the present invention, since the contact portion to be placed on the upper end portion of the lower tub portion is connected to the engaging protrusion, the vertical position of the partition plate in the septic tank can be defined. Therefore, it becomes easy to ensure a constant gap between the lower end of the partition plate and the bottom surface of the lower tank part. For example, the partition plate is more firmly fixed by interposing an adhesive or the like in the gap. can do.

Next, the upper tub portion 1a is covered from above, and the upper peripheral portion of the partition plate 2 is inserted into the fitting groove 3 of the upper tub portion 1a to be fitted and fixed.

図１０〜図１２は、仕切板２を、上槽部分１ａと下槽部分１ｂの内側に設置したときの様子を示している（図１０は、被係合凹部１３周縁の平面図であり、図１１は、被係合凹部１３周縁の縦断面図であり、図１２は、下槽部分１ｂの底部における嵌合溝３部分の縦断面図である）。   10-12 has shown the mode when the partition plate 2 was installed inside the upper tank part 1a and the lower tank part 1b (FIG. 10 is a top view of the to-be-engaged recessed part 13 periphery, FIG. 11 is a longitudinal sectional view of the periphery of the recessed portion 13 to be engaged, and FIG. 12 is a longitudinal sectional view of the fitting groove 3 portion at the bottom of the lower tank portion 1b.

図１１に示されるように、上槽部分１ａと下槽部分１ｂとを組付けた際、仕切板２の係合突起部９は、上槽部分１ａの被係合凹部１３及び下槽部分１ｂの被係合凹部１３の両方にわたって係合し得る構成となっている。
即ち、一対の係合突起部９は、上層部分１ａの対向壁１２夫々に設けられた被係合凹部１３に各別に係合して、上層部分１ａの対向壁１２間の距離が開くのを防止し得ると共に、下槽部分１ｂについても同様に、下層部分１ｂの対向壁１２夫々に設けられた被係合凹部１３に各別に係合して、下層部分１ｂの対向壁１２間の距離が開くのを防止し得る。 As shown in FIG. 11, when the upper tank part 1a and the lower tank part 1b are assembled, the engaging protrusions 9 of the partition plate 2 are engaged with the engaged recesses 13 and the lower tank part 1b of the upper tank part 1a. It is the structure which can be engaged over both of the to-be-engaged recessed parts 13.
That is, the pair of engaging protrusions 9 are engaged with the respective recessed portions 13 provided on the opposing walls 12 of the upper layer portion 1a, respectively, so that the distance between the opposing walls 12 of the upper layer portion 1a is increased. Similarly, the lower tank portion 1b can be engaged with the engaged recesses 13 provided on the opposing walls 12 of the lower layer portion 1b, respectively, and the distance between the opposing walls 12 of the lower layer portion 1b can be reduced. It can be prevented from opening.

また、仕切板２を設置する際、上述のように、仕切板２の係合突起部９が、上槽部分１ａの被係合凹部１３及び下槽部分１ｂの被係合凹部１３に係合すると、係合突起部９に連設する接当部１０が、下槽部分１ｂの槽内リブの端面１５ｂ（下槽部分１ｂの上端部）に載置されると共に、その接当部１０の上に、上槽部分１ａの槽内リブの端面１５ａ（上槽部分１ａの上端部）が載置される構成となっている。また、図１１に示されるように、被係合凹部１３の幅と深さは、係合突起部９より大きく形成し、係合突起部９のテーパー面１６以外の面は、被係合凹部１３に突き当たることがないように形成している。このため、上槽部分１ａと下槽部分１ｂが接合した時点で仕切板２が上下方向に対して位置決めされる。
また、係合突起部９の浄化槽内側方向の面は、被係合凹部１３の浄化槽内側方向の角部（被係合凹部１３開口部の面取り終端部）に対して摺接し得るテーパー面１６が形成されている。このため、仕切板２を挿入するに従い、外槽と仕切板２が締め付け合い、上槽部分１ａと下槽部分１ｂが接合した時点で、外槽と仕切板２が水平方向に対して位置決めされ、仕切板２のガタつきを防止することができる。
尚、周縁リブ１１は、図３及び図１１に示されるように、仕切板の両端部と下端部（全周に設けても良い）に形成され、仕切板２の反りを防止すると共に、外圧等で外槽が内側に入り込まないようにするストッパーとしての機能を有している。 Further, when the partition plate 2 is installed, as described above, the engaging projection 9 of the partition plate 2 is engaged with the engaged recess 13 of the upper tank portion 1a and the engaged recess 13 of the lower tank portion 1b. Then, the contact portion 10 connected to the engaging projection portion 9 is placed on the end face 15b of the inner rib of the lower tank portion 1b (the upper end portion of the lower tank portion 1b), and the contact portion 10 The end surface 15a (the upper end portion of the upper tank portion 1a) of the in-tank rib of the upper tank portion 1a is placed on the top. Further, as shown in FIG. 11, the width and depth of the engaged recess 13 are formed larger than those of the engaging projection 9, and the surfaces other than the tapered surface 16 of the engaging projection 9 are engaged recesses. 13 is formed so as not to hit 13. For this reason, when the upper tank part 1a and the lower tank part 1b join, the partition plate 2 is positioned with respect to an up-down direction.
In addition, the surface of the engaging projection 9 in the inner side of the septic tank has a tapered surface 16 that can be in sliding contact with the corner of the engaged recess 13 in the inner side of the septic tank (the chamfering end portion of the opening of the engaged recess 13). Is formed. For this reason, as the partition plate 2 is inserted, the outer tub and the partition plate 2 are fastened together, and when the upper tub portion 1a and the lower tub portion 1b are joined, the outer tub and the partition plate 2 are positioned with respect to the horizontal direction. The rattling of the partition plate 2 can be prevented.
As shown in FIGS. 3 and 11, the peripheral rib 11 is formed at both end portions and lower end portions (may be provided on the entire circumference) of the partition plate to prevent warping of the partition plate 2 and to apply external pressure. It has a function as a stopper that prevents the outer tub from entering the inside.
