Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling devices, in particular to a sampling device for municipal sewage treatment. Background Art

[0002] In municipal sewage treatment, the sewage is a water source with large water quality changes and is very difficult to treat. The concentrations of total dissolved solids, COD, BOD, total silicon, ammonia and some other pollutants change very frequently. In addition, the sewage before treatment contains high concentrations of organic matter, microorganisms, etc. Therefore, any product designed to treat reclaimed water must be able to tolerate this variability and contain high concentrations of organic matter and active organisms. In municipal sewage treatment, it is necessary to purify the water quality in the sewage in a targeted manner, so it is often necessary to sample and test the sewage to determine the sewage quality.

[0003] When sampling sewage, workers are required to carry containers to collect sewage. When sewage at different depths needs to be collected, users are required to carry multiple sets of equipment or collect sewage at different depths in batches for multiple times, which is very inconvenient and time-consuming. For this reason, we propose a sampling device for municipal sewage treatment. Utility Model Content

[0027] The utility model provides Figure 1-4 A sampling device for municipal sewage treatment shown in the figure comprises a hanging wheel 1, a sampling tube 2 is connected to the bottom end of the hanging wheel 1, and a protective frame 3 is arranged at the bottom end of the sampling tube 2, the hanging wheel 1 comprises a wheel frame 101, and a motor 102 is connected to one side of the wheel frame 101, a handle 103 is connected to the top end of the wheel frame 101, and a hanging rope 104 is connected to the bottom end of the wheel frame 101, and the bottom end of the hanging rope 104 is connected to the sampling tube 2;

[0028] In order to improve the convenience of using this sampling device in sampling in deeper waters, Figure 1As shown, this sampling device is connected to the sampling tube 2 via a hanging wheel 1, and the connected sampling tube 2 can be driven by adjusting the hanging rope 104 to take samples in waters of different depths in a municipal environment, and one side of the wheel frame 101 is connected via a motor 102, so the folding and unfolding process is convenient, providing convenience for the user.

[0029] like Figure 2-3 As shown, the sampling cylinder 2 includes a cylinder body 201, and a micro peristaltic pump 202 is arranged inside the bottom end of the cylinder body 201, a suction tube 203 is connected to one side of the bottom end of the micro peristaltic pump 202, and a control module 204 is arranged on the top of the micro peristaltic pump 202, a shunt tube 205 is connected to one side of the top end of the micro peristaltic pump 202, and a solenoid valve 206 is connected to one side of the shunt tube 205, a connection pile 207 is connected to one side of the solenoid valve 206, and a sampling bottle 208 is connected to one end of the connection pile 207;

[0030] In order to complete the sampling operation at different depths in the water area at one time, such as Figure 2-3 As shown, this sampling device is placed in the sewage area through the cylinder 201 for sampling operation. During operation, the connected suction tube 203 is driven by the micro peristaltic pump 202 to perform suction sampling. At the same time, when it is in different depths of the water area, as the water area progresses, the solenoid valve 206 connected to the diversion tube 205 is also opened in sequence, and samples are taken in sequence through the connected sampling bottle 208, thereby completing the sampling of water samples in multiple depths of water areas at one time, saving multiple repeated sampling processes, and improving the sampling efficiency in deep water areas.

[0031] like Figure 4 As shown, the protection frame 3 includes a bottom frame 301, and the top of the bottom frame 301 is connected to the bottom of the sampling tube 2, the outer wall of the sampling tube 2 is connected to the outer wall layer 302, and the inner wall of the outer wall layer 302 is connected to the connecting frame 303;

In this way, as the water depth changes, the solenoid valve 206 is gradually opened to cooperate with the depth of batch sampling.
