Description
Technical Field
The utility model relates to a sedimentation tank drainage system in the field of sewage treatment.
Background
At the sewage treatment station, the sedimentation tank is used for removing suspended matters in water. The effluent of the sedimentation tank is usually discharged into a hydrolysis acidification tank through a drain pipe; when the sedimentation tank is overhauled, the wastewater is required to be discharged into the regulating tank through the emptying pipe. The hydrolysis acidification tank and the regulating tank are both of closed structures, and the tank contains odor such as ammonia, sulfur and the like. In order to avoid sludge accumulation at the bottom of the hydrolysis-acidification tank or the regulating tank, a drain pipe or an emptying pipe connecting the hydrolysis-acidification tank and the regulating tank is usually arranged at the middle and upper part of the tank wall, when the liquid level in the tank changes and the upper edge of the drain pipe or the emptying pipe is positioned above the sewage liquid level, odor and other odor gases in the hydrolysis-acidification tank or the regulating tank can reversely flow into a sedimentation tank through the drain pipe or the emptying pipe, and the sedimentation tank is usually opened and arranged in a device room. As the sedimentation tank drainage system in the prior art lacks a hydrolysis acidification tank or an adjusting tank odor reverse-string protection mechanism, air pollution in equipment can be caused, and the physical health of equipment operators is damaged.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a sedimentation tank drainage system, when the liquid level in a hydrolysis acidification tank or a regulating tank is reduced, the water outlet end of a drain pipe or an emptying pipe is automatically and temporarily closed so as to prevent peculiar smell gas in the hydrolysis acidification tank or the regulating tank from reversely flowing into the sedimentation tank.
The technical scheme of the utility model is as follows:
the sedimentation tank drainage system comprises a sedimentation tank, an adjusting tank and a hydrolysis acidification tank, wherein a drain pipe communicated with the sedimentation tank is arranged on the tank wall of the hydrolysis acidification tank, an emptying pipe communicated with the sedimentation tank is arranged on the tank wall of the adjusting tank, a port of the drain pipe connected with the hydrolysis acidification tank and a port of the emptying pipe connected with the adjusting tank are respectively connected with an odor-preventing reverse-serial drainage mechanism positioned in the hydrolysis acidification tank and the adjusting tank; the odor-resistant reverse-serial drainage mechanism comprises a rigid connecting pipe connected with the port; the rigid connecting pipe is connected with a flexible pipe.
Preferably, the free end of the flexible tube is provided with two magnets which are opposite to each other.
Preferably, the flexible tube is connected with a balancing weight.
The utility model has the positive effects that:
according to the utility model, the drain pipe and the drain pipe water outlet end of the sedimentation tank are both provided with the odor-resistant reverse-serial drain mechanism, and when the liquid level in the hydrolysis acidification tank or the regulating tank is lower than that of the drain pipe or the drain pipe, the tail end of the flexible pipe of the odor-resistant reverse-serial drain mechanism is in a closed state or is positioned below the liquid level, so that the odor can be effectively prevented from reversely flowing into the sedimentation tank pen to pollute the air in the equipment room.
The pipeline serving as the water outlet section of the anti-odor anti-series drainage mechanism is a flexible pipe, and the free end of the flexible pipe is provided with a magnet/balancing weight, so that the outer port of the flexible pipe is ensured to be below the liquid level in the hydrolysis-acidification tank or the regulating tank, and even if the water level is too low, the outer port of the flexible pipe is positioned above the liquid level, the port can also prevent the odor in the hydrolysis-acidification tank or the regulating tank from entering a drain pipe or an emptying pipe by means of the attraction of the magnet, thereby playing a good role of preventing the anti-odor anti-series.
Thirdly, the flexible pipe used as the water outlet section is more convenient to clean. The flexible pipe is very convenient to clean by kneading and the like when the sludge is accumulated in the flexible pipe.

Detailed Description
The utility model is described in detail below with reference to the drawings and examples.
As shown in fig. 1, an embodiment of the sedimentation tank drainage system of the present utility model includes a sedimentation tank 1, a regulating tank 2, and a hydrolytic acidification tank 5. The wall of the hydrolytic acidification tank 5 is provided with a drain pipe 6 communicated with the sedimentation tank 1, and the wall of the regulating tank 2 is provided with an emptying pipe 4 communicated with the sedimentation tank 1. The port of the drain pipe 6 connected with the hydrolysis acidification tank 5 and the port of the drain pipe 4 connected with the regulating tank 2 are respectively connected with an anti-odor anti-series drain mechanism 3 positioned in the hydrolysis acidification tank 5 and the regulating tank 2.
As shown in fig. 2, the anti-odor anti-series drainage mechanism 3 comprises a rigid connection pipe 31 connected to the port and in the form of a short pipe, the rigid connection pipe 31 being connected with a flexible pipe 32. Specifically, the port is mounted with an inner flange 34, the rigid connection pipe 31 is connected with an outer flange 33, and the inner flange 34 and the outer flange 33 are connected with each other by bolts.
The rigid connection pipe 31 is generally made of stainless steel or UPVC. The flexible tubing 32 is typically made of a corrosion resistant polymeric material such as a tri-proof cloth.
The free end of the flexible tube 32 is provided with two magnets positioned opposite each other. During non-drain/drain periods, the free end port is closed by the attraction of the magnet. When the pipeline is drained/emptied, the free end port is naturally opened under the impact of water flow, so that no extra resistance loss is generated, and the drainage water quantity is not influenced.
To allow the free end to sag better, a weight is attached to the outer end of the flexible tube 32.
