Description

Technical Field

[0001] The utility model relates to the technical field of pretreatment in sewage treatment industry, and in particular to a sampling pipeline cleaning and dredging system for a sewage treatment plant. Background Art

[0002] During the sewage treatment process, the inlet and outlet water have online monitoring and detection samplers to detect the inlet and outlet water data in real time. In addition, the water plant has installed a separate sewage sampler to collect mixed samples for testing, to detect the daily process indicators in real time, and to provide timely feedback for the stability of process operation; and the sampling pipeline of the sewage sampler often fails to take samples, runs idle, and has pipeline blockages during normal operation. The main causes of pipeline blockages include pipeline blockages caused by accumulation of sludge and suspended matter; because the sampling equipment is sampled at a fixed time and at a fixed point, and after the blockage, the relevant post employees repair and adjust the equipment pipelines. This normalized maintenance process seriously affects the normal operation of the equipment and pipelines, and the long-term idle equipment can only be converted from equipment sampling to manual sampling, which puts greater pressure on the overall environmental protection work.

[0003] In the prior art, the mixed sample sampler in the water plant uses an ordinary clean water pump to extract sewage through a PVC25 pipe to the vicinity of the sampler, and then uses the sampling tube on the sampler to collect samples from the PVC25 pipe for storage. The sampling pipe is a 9mm diameter rubber hose. Generally, when the pipe is blocked, the on-site staff will handle the operation by cleaning the garbage near the pump body of the sampling pump, adjusting the clean water pump flow to the maximum flushing pipe, and determining the blockage location by disassembling the existing pipe joints, and cutting off the relevant blocked pipes for replacement. Due to the thick silt in the running pipe, the sampling pipe is prone to clogging, and the equipment manufacturer has been contacted many times for guidance on cleaning and replacing the rubber hose. The above maintenance and processing methods have the defects of increased employee workload, maintenance costs higher than the value of the pipe, and reduced life of the equipment due to long-term idleness and repeated maintenance. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a sewage treatment plant sampling pipeline cleaning and dredging system to solve the problems of pipeline blockage, idling of samplers, inability to take samples, and long-term idle equipment requiring repeated repair and cleaning; it greatly reduces maintenance costs and operator workload and improves work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model designs a sewage treatment plant sampling pipeline cleaning and dredging system, including a water storage tank, the water storage tank is connected to a water inlet pipe, the water inlet end of the water inlet pipe is provided with a submersible sewage pump, the submersible sewage pump is used to extract sewage to be sampled from the sewage treatment plant, the water storage tank is connected to a sampling pipe, the other end of the sampling pipe is connected to a sampler, and the water inlet pipe is connected to a flushing pipe.

[0006] Preferably, a drain pipe is provided at the bottom of the water storage tank.

[0007] Preferably, the drain pipe is a PVC pipe.

[0008] Preferably, a one-way valve is provided on the water inlet pipe.

[0009] Preferably, a solenoid valve is provided on the flushing pipeline.

[0010] Preferably, a flushing branch pipe is provided on the flushing pipeline, and the water outlet end of the flushing branch pipe is connected to the water storage tank.

[0011] Preferably, a solenoid valve is provided on the flushing branch pipe.

[0012] Preferably, the water inlet pipe, sampling pipe and flushing pipe are PVC pipes.

[0013] Beneficial effects of the utility model:

[0014] The utility model of the pipeline cleaning and unblocking system is equipped with a water storage tank at the sampling location of the running pipeline sampler. The main function of the water storage tank is to ensure that sewage is extracted every time the sampler samples when the equipment is linked to operate; the water storage tank and the water inlet pipe are bridged to flush the pipe, and after the sampling is completed through the control of the sampler linkage solenoid valve, the recycled water in the flushing pipe is used to flush the water storage tank and the water inlet pipe; after cleaning and unblocking the pipe, the representativeness of the sewage sampled by the sampler is not affected, and the whole flushing process can be achieved through linkage and manual methods. It solves the problems of pipeline blockage, idling of the sampler, inability to sample, and repeated maintenance and cleaning of equipment when the equipment is idle for a long time; it greatly reduces the maintenance cost and the workload of operators, and improves work efficiency.

[0030] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1The sewage treatment plant sampling pipeline cleaning and dredging system shown comprises a water storage tank 1, and a PVC drain pipe 11 is provided at the bottom of the water storage tank 1. The water storage tank 1 is connected to a PVC water inlet pipe 2, and a one-way valve 21 is provided on the water inlet pipe 2. A submersible sewage pump 3 is provided at the water inlet end of the water inlet pipe 2, and the submersible sewage pump 3 is used to extract sewage to be sampled from the sewage treatment plant. A PVC sampling pipe 4 is connected to the water storage tank 1, and a sampler 5 is connected to the other end of the sampling pipe 4. A PVC flushing pipe 6 is connected to the water inlet pipe 2. A solenoid valve 7 is provided on the flushing pipe 6.

[0033] The flushing pipeline 6 is provided with a flushing branch pipe 61, and the water outlet end of the flushing branch pipe 61 is connected to the water storage tank 1. The flushing branch pipe 61 is provided with a solenoid valve 7.

[0034] The following is an introduction to the process flow of the system when it is working in conjunction with an embodiment:

[0035] During the sampling process, the sewage to be tested is extracted by the submersible sewage pump 3 and enters the water tank 1 through the water inlet pipe 2, ensuring that there is enough sewage to be tested in the water tank 1 to meet the sampling requirements of the sampling tube 4 in time, avoiding the situation where the sampler 5 runs idle or cannot retain samples. The sampler 5 has the function of extracting and discharging sewage. The sewage to be tested in the water tank 1 is extracted through the sampling tube 4 and enters the sampler 5 for sampling. After the equipment sampling is completed, the submersible sewage pump 3 stops running, and the tested sewage is discharged to the sampling tube 4 through the sampler 5 and then to the water tank 1. The water tank 1 is discharged from the emptying pipe 10. At the same time, the flushing pipe 6 is linked to the solenoid valve 7 to open, and the recycled water is used to flush the water inlet pipe 2, and the water tank 1 discharges silt and other deposits through the emptying pipe 11 to ensure that the water inlet pipe 2, the water tank 1, and the emptying pipe 11 are unobstructed.

[0036] Example 2

[0037] The other structures of Example 2 are substantially the same as those of Example 1, except that the flushing branch pipe 61 and the 7 solenoid valves provided on the flushing branch pipe 61 are reduced. During the flushing process, the flushing water is discharged from the flushing pipe 6 to the water storage tank 1 through the water inlet pipe 2 for flushing. The flushing effect on the water storage tank 1 is slightly lower than that of Example 1, but the manufacturing cost is further saved. The details are as follows:

[0038] like Figure 2The sewage treatment plant sampling pipeline cleaning and dredging system shown comprises a water storage tank 1, and a PVC drain pipe 11 is provided at the bottom of the water storage tank 1. The water storage tank 1 is connected to a PVC water inlet pipe 2, and a one-way valve 21 is provided on the water inlet pipe 2. A submersible sewage pump 3 is provided at the water inlet end of the water inlet pipe 2, and the submersible sewage pump 3 is used to extract sewage to be sampled from the sewage treatment plant. A PVC sampling pipe 4 is connected to the water storage tank 1, and a sampler 5 is connected to the other end of the sampling pipe 4. A PVC flushing pipe 6 is connected to the water inlet pipe 2. A solenoid valve 7 is provided on the flushing pipe 6.
