Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water sample collection pipeline structure. Background Art

[0002] Municipal domestic sewage treatment plants are facilities that treat sewage generated by the daily lives of urban residents. The main purpose of a sewage treatment plant is to purify sewage through a series of physical, chemical, and biological processes, so that it meets certain water quality standards before being discharged into natural water bodies or reused. In municipal domestic sewage treatment plants, water quality is usually sampled at each treatment stage. Sampling pipes are generally installed for water transmission, and valves are installed at the end of the sampling pipes. When sampling is required, the valves are opened to collect water. However, since sewage contains various impurities and suspended matter, and water quality sampling is performed at intervals, if the water in the sampling pipe is left stagnant for a long time, impurities and suspended matter will be adsorbed and accumulated on the inner wall of the pipe. Over time, this can cause pipe blockage, hindering sampling operations and increasing maintenance costs. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a water sample collection pipeline structure that facilitates sampling operations and reduces the risk of pipeline blockage.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A water sample collection pipeline structure includes a horizontally extending sampling tube, a sampling cup that is connected to the sampling tube and arranged vertically and is fixedly connected to the top of the tube body of the sampling tube, an S-shaped sewage pipe is arranged at the rear end of the sampling tube, the flow area of ​​the S-shaped sewage pipe is larger than the flow area of ​​the sampling tube, the S-shaped sewage pipe is arranged vertically, one end of the S-shaped sewage pipe is upwardly connected to the rear end of the sampling tube, and the other end is arranged downward, the top height of the inner hole of the upper bend section of the S-shaped sewage pipe is lower than the cup mouth height of the sampling cup, and a sewage valve is installed at the lower bend section of the S-shaped sewage pipe.

[0006] In the present invention, sewage enters from the front end of the sampling tube, and flows downward from the rear end of the sampling tube into the S-shaped drain pipe, and is finally discharged downward from the S-shaped drain pipe. Since the flow area of ​​the S-shaped drain pipe is greater than or equal to the flow area of ​​the sampling tube, and the top height of the inner hole of the upper bend section of the S-shaped drain pipe is lower than the height of the cup mouth of the sampling cup, the sewage in the sampling tube will not overflow from the cup mouth of the sampling cup, making it convenient for the operator to sample the water quality from the position of the sampling cup; in addition, the sewage is in a flowing state in both the sampling tube and the upper bend section, so impurities and suspended matter in the sewage are not easy to settle, and therefore are not easy to cause pipe blockage; and by opening the drain valve, larger impurities in the lower bend section of the S-shaped drain pipe can also be discharged.

[0007] As an optimization, the S-shaped sewage pipe includes an upper straight pipe and a lower straight pipe located in the same vertical plane and arranged parallel to each other. The upper straight pipe and the lower straight pipe are both horizontally extended. The front end of the lower straight pipe is connected to the rear end of the sampling pipe through a front vertical pipe. The front end of the upper straight pipe is connected to the rear end of the pipe body of the lower straight pipe through a middle vertical pipe. The sewage valve is installed at the rear end pipe mouth of the lower straight pipe, and the rear end of the upper straight pipe is connected to the rear end vertical pipe. The more elbows there are in the water pipe, the lower the flow rate of the water flow. Therefore, in the utility model, after opening the sewage valve, the sewage does not have any turning in the lower straight pipe, and the pressure in the front is reduced. Therefore, the flow rate of the sewage in the lower straight pipe can be increased, and the debris in the lower straight pipe can be better flushed out.

[0008] As an optimization, the outlet end of the sewage valve is connected to the pipe body of the rear end vertical pipe. The flushed sewage and debris enter the rear end vertical pipe, which is convenient for sewage backflow treatment.

[0009] As an optimization, the connection position between the front vertical pipe and the lower straight pipe is located at the front end of the top of the tube body of the lower straight pipe. A flange is provided at the front end of the lower straight pipe and a sealed end cap is connected to the flange. The end cap is made of non-magnetic material. A magnetic and strip-shaped stirring terminal is provided on one side of the end cap located in the inner hole of the lower straight pipe. A magnetic drive device that can drive the stirring terminal to rotate on the end cap is installed on the side of the end cap facing away from the lower straight pipe. The magnetic drive device can drive the stirring terminal on the end cap to rotate, thereby stirring the sewage in the S-shaped sewage pipe to prevent suspended matter from settling and adhering to the pipe; and when the sewage valve is opened, the rotating water flow can also wash away impurities attached to the pipe wall. In addition, the use of magnetic stirring not only has a simple structure, but also avoids water leakage.

[0010] As an optimization, the magnetic drive device includes a drive motor spaced apart from the end cover and a mounting platform fixed to the drive motor, the mounting platform is fixedly connected to the flange, the drive motor extends toward one side of the end cover with a drive shaft arranged on the same center line as the lower straight tube, the drive shaft is fixedly connected to the drive shaft, and two magnets are symmetrically fixedly connected to the rotating disk with the center line of the drive shaft as the axis of symmetry, the positive pole of one magnet corresponds to the magnetic negative pole of the stirring terminal, and the negative pole of the other magnet corresponds to the magnetic positive pole of the stirring terminal. When the drive motor drives the rotating disk to rotate, the two magnets can drive the stirring terminal to rotate.

[0011] As an optimization, a mesh cover is fixedly connected to the side of the end cap on the side where the stirring terminal is located. A limited rotation space is formed between the mesh cover and the end cap, and the stirring terminal is located within the limited rotation space. This can prevent the stirring terminal from falling off the end cap after the magnetic drive device is removed for maintenance.

[0012] Compared with the prior art, the present invention has a simple structure. The S-shaped sewage pipe arranged according to the principle of the communicating vessel not only facilitates the sampling operation, but also avoids pipeline blockage and is easy to maintain.
