Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure for discharging treated water from a disinfection chamber provided in a septic tank.

[Prior Art] Conventionally, the structure for discharging from the disinfection chamber 2 in the septic tank 1 is the fifth
It is constructed as shown in FIGS. 6, 6 and 7. The discharge port sleeve 5'is inserted through the through hole 3 provided on the side wall of the disinfection chamber 2 and the through hole 4 provided on the side wall of the septic tank, and the discharge port fixing nut 6'is screwed to the discharge port sleeve 5'outside the septic tank 1. The discharge pipe 7 is connected to the discharge sleeve 5 '. Between the collar portion 5a 'of the outlet sleeve 5'and the side wall of the disinfection chamber 2, and between the side wall of the disinfection chamber 2 and the side wall of the septic tank 1, packings 8 and 9 are renovated. Further, in the figure, 10 is a chemical pipe for supplying a chemical, 11 is a first anaerobic hearth chamber, 12 is a second anaerobic hearth chamber, 13 is a contact aeration chamber, 14 is a precipitation chamber, 15 is an aeration device, and 16 is It is an air diffuser.

[Problems to be Solved by the Invention] By the way, the packing 8 between the collar portion 5a 'and the side wall of the disinfection chamber 2 of the above-mentioned conventional example has a packing 8 between the chlorine-disinfected water in the disinfection chamber 2 and the septic tank 1
The packing 8 has a short service life and is damaged by chemicals in order to prevent it from flowing into the interior of the septic tank 1 without disinfecting it. Leakage and inflow occur. If it leaks from the disinfection room 2,
There is a problem that the chemicals flow out into the septic tank 1 and the purification function is deteriorated due to the death of bacteria for maintaining the septic tank function. Further, when the sewage flows from the septic tank 1 into the disinfection chamber 2, the sewage is not treated and the sewage is clarified. There is a problem of leaking out. Further, there is a problem that the above-mentioned trouble may occur due to a work mistake when mounting the packing 8. Further, if the disinfection chamber 2 and the discharge sleeve 3'are made of polyethylene, polypropylene or the like, the discharge pipe 7 cannot be connected by adhesion because it is vinyl chloride, and the discharge pipe 7 cannot be reliably connected.

The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to prevent leakage from the disinfection chamber and inflow into the disinfection chamber to prevent septic tank troubles and to improve the assemblability of the disinfection chamber. An object of the present invention is to provide a discharge structure of a disinfection chamber of a septic tank which can be improved and can be easily connected to the discharge pipe by adhesion.

[Means for Solving the Problems] In order to achieve the above object, the discharge structure of the disinfection chamber of the septic tank of the present invention has a disinfection chamber 2 inside the septic tank 1 and a disinfection chamber 2
An outlet sleeve 5 integrally provided to project from the disinfection chamber 2 so as to communicate with the inside is projected from the through hole 4 on the side wall of the septic tank 1 to the outside of the tank, and the outlet connection sleeve 6 is screwed to the outlet sleeve 5 outside the tank. Fixing the outlet sleeve 6 to the side wall of the septic tank 1,
The male screw 18a of the connection socket 18 was screwed into the female screw 6c of the discharge port 6a of the discharge port connection sleeve 6 to connect the connection socket 18 to the discharge port connection sleeve 6 and the discharge pipe 7 to the connection socket 18.

[Operation] By disposing the disinfection chamber 2 and the discharge port sleeve 5 integrally, and fixing the discharge port connection sleeve 6 to the discharge port sleeve 5 by screwing them outside the tank, a portion leaking from the disinfection chamber 2 into the septic tank 1 or There is no part that directly flows from the septic tank 1 to the disinfection chamber 2,
The trouble of the purifying function is eliminated, and the assembling property of the disinfection chamber 2 can be improved. Further, the male screw 18a of the connection socket 18 is connected to the female screw 6 of the outlet 6a of the outlet connection sleeve 6.
Since the connection socket 18 is connected to the discharge port connection sleeve 6 by screwing with the c and the discharge pipe 7 is connected to the connection socket 18, the discharge port connection sleeve 6 and the discharge pipe 7 are made of different resin materials. Also, by connecting the connection socket 18 made of the same material as that of the discharge pipe 7 to the discharge port connection sleeve 6 by screwing, the discharge pipe 7 can be attached to the connection socket 18 and the discharge pipe 7 can be reliably connected by adhesion. .

[Example] As shown in FIG. 1, the first anaerobic hearth chamber 1 is provided in the septic tank 1.
1, a second anaerobic hearth chamber 12, a contact aeration chamber 13, a precipitation chamber 14, an aeration device 15, an air diffuser 16 and the like are provided. A wastewater inflow pipe 7 is introduced into one side of the septic tank 1, and a treated wastewater discharge pipe 7 is led out from the other side of the septic tank 1. The disinfection chamber 2 is installed inside the septic tank 1 on the discharge pipe 7 side. 2 and 3
As shown in the figure, the disinfection chamber 2 is integrally provided with an outlet sleeve 5 that communicates with the inside of the disinfection chamber 2, and the outlet sleeve 5 is inserted from the through hole 4 on the side wall of the septic tank 1 to the outside of the septic tank 1. . At this time, packing 9 is interposed between the side wall of the disinfection chamber 2 and the side wall of the septic tank 1. The outlet connection sleeve 6 is provided with an outlet 6a and a nut portion 6b, and the nut portion 6b of the outlet connection sleeve 6 is screwed onto the outlet sleeve 5 outside the septic tank 1. The discharge pipe 7 is connected to the discharge port 6 a of the discharge connection sleeve 6 via a connection socket 18. The connection socket 18 is made of vinyl chloride, which is the same material as the discharge pipe 7. As shown in FIG. 4, the male screw 18a of the connection socket 18 is screwed into the female screw 6c of the discharge port 6a, and the discharge port connection sleeve. 6, the connection socket 18 is connected, and the discharge pipe 7 is connected to the connection socket 18 by adhesion.

[Effect of the Invention] As described above, the present invention has the discharge sleeve integrally protruding from the disinfection chamber, so that there is no part that leaks due to packing damage or assembly mistake as in the conventional case, and the outflow of the drug is prevented. In addition to being able to prevent the outflow of untreated sewage, it is possible to improve the assembling property of the disinfection chamber by simplifying the work of attaching the packing and fixing it to the septic tank. In addition, the male screw of the connection socket is screwed into the female screw of the outlet of the outlet connection sleeve to connect the outlet socket to the outlet socket and to connect the outlet pipe to the outlet socket. Even if different resin materials are used, by connecting a connection socket made of the same resin material as the discharge pipe to the discharge port connection sleeve by screwing, the discharge port can be easily and reliably connected to the connection socket by adhesion. Is.
