Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment sampling, and in particular to a municipal wastewater treatment sampling device. Background Technology
[0002] Municipal wastewater treatment sampling refers to the collection and analysis of water samples during the municipal wastewater treatment process to assess the wastewater treatment effectiveness and ensure that water quality meets standards. The sampling process includes selecting appropriate sampling points, sampling equipment, and storage containers to ensure that the collected water samples are representative and accurately reflect the wastewater treatment effect. The main purpose of municipal wastewater treatment sampling is to evaluate the wastewater treatment effect and ensure that the treated water quality meets discharge standards. Through regular sampling and analysis, problems in the treatment process can be identified in a timely manner, and corresponding measures can be taken for adjustment and optimization. The sampling standards and methods must comply with relevant environmental monitoring standards and regulations to ensure the accuracy and reliability of the data.
[0003] For example, patent number (CN222299258U) discloses a municipal sewage treatment sampling device, including a suction tube. A diversion ball is fixedly connected to the middle of the suction tube. A circular tube is elastically connected to the inner wall of the diversion ball via a torsion spring. An insert plate is elastically connected to the inner wall of the right end of the circular tube via a return spring. A shielding ring is fixedly connected to the outer wall of the circular tube. A connecting tube is fixedly connected to the outer wall of the diversion ball. A sampling tube is provided at the end of the connecting tube. A fixing mechanism is provided on the outer wall of the suction tube. In this utility model, by rotating the circular tube, the shielding ring is rotated 180 degrees, which allows the shielding ring to block any one of the connected points on both sides of the diversion ball. This prevents the sampled tube from mixing with other sewage samples, enabling sampling and processing of water samples from different sewage tanks. The operation is simple and convenient, improving the practicality of the device to a certain extent.

An mounting plate 5 is fixedly installed at the upper end of the connecting sleeve 1. A drive motor 6 is fixedly installed on the left side of the upper end of the mounting plate 5. The output end of the drive motor 6 extends into the interior of the connecting sleeve 1 and a drive shaft 7 is fixedly installed thereon. The lower end of the drive shaft 7 extends into the interior of the protective mesh cover 4, and a stirring blade 8 is fixedly installed on its surface. A sampling liquid pump 9 is fixedly installed on the right side of the upper end of the mounting plate 5, and a sampling liquid pump 9 is fixedly connected to the lower end of the sampling liquid pump 9. The right end of the hose 10 and the sampling pump 9 is fixedly connected to a water storage box 11. A connecting pipe port 12 is fixedly installed on the rear side of the upper end of the protective net cover 4. A pressure balancing pipe 13 is fixedly installed on the right side of the upper end of the water storage box 11. The driving motor 6 drives the stirring blade 8 to stir and rotate, forming a liquid flow, thereby maintaining the fluidity of the sewage in the space. This can avoid sedimentation and stratification that may occur in the water space, and at the same time avoid only collecting sewage from a fixed area. The sewage sample is pumped by the sampling pump 9 and the sampling hose 10 and pumped into the water storage box 11. The pressure balancing pipe 13 is used to balance the pressure inside and outside the equipment, making it easier for the sewage sample to enter the sampling bottle 2.
[0026] Please see Figures 1-4 In this embodiment, a control button is fixedly installed on the upper end of the drive motor 6. The output end of the drive motor 6 is rotatably connected to the mounting plate 5. The transmission shaft 7 is sleeved with the connecting sleeve 1. The surface of the transmission shaft 7 is rotatably connected to the connecting ring 3. The stirring blade 8 has a centrally symmetrical structure design. The stirring blade 8 is adapted to the protective net cover 4. The sampling end of the sampling device is inserted into the sewage. The drive motor 6 drives the transmission shaft 7 to rotate, so that the stirring blade 8 stirs and rotates in the sewage to form a liquid flow, thereby maintaining the fluidity of the sewage in the space and improving the accuracy of sewage sample detection.
[0027] Please see Figures 1-5 In this embodiment, an anti-slip grip 14 is fixedly installed on the upper side of the connecting sleeve 1, a control button 2 is fixedly installed on the upper end of the sampling liquid pump 9, the upper end of the water storage box 11 is fixedly connected to the mounting plate 5, the end of the sampling hose 10 away from the sampling liquid pump 9 is connected to the connecting pipe port 12, the upper side of the sampling bottle 2 is threadedly connected to the water storage box 11, a transparent observation window 15 is fixedly installed on the right end of the water storage box 11, and an inclined baffle 16 is fixedly installed on the inner surface of the air pressure balance pipe 13.

The air pressure balance pipe 13, in conjunction with the internal and external pressure of the equipment, facilitates the sewage sample to enter the sampling bottle 2.
[0028] During operation, the sampling end of the sampling device is inserted into the sewage. The drive motor 6 drives the transmission shaft 7 to rotate, causing the stirring blades 8 to stir and rotate in the sewage, forming a liquid flow. This maintains the fluidity of the sewage in the space, further ensuring that the collected sewage sample is more uniform and improving the accuracy of sewage sample testing. The sampling liquid pump 9 is started, and the sewage sample is pumped through the sampling hose 10. With the help of the protective net cover 4, some larger impurities are blocked to avoid clogging the sampling hose 10. The sewage sample is pumped into the water storage box 11. The air pressure balancing pipe 13 is used to balance the internal and external pressure of the equipment, making it easier for the sewage sample to enter the sampling bottle 2, thus completing the municipal sewage treatment sampling work.
[0029] Through the above steps, the drive motor 6 drives the stirring blades 8 to rotate and form a liquid flow, thereby maintaining the fluidity of the sewage in the space. This can avoid the possible sedimentation and stratification within the water space, and also avoid the problem of only being able to collect sewage from a fixed area. This solves the problem that sewage sampling devices can only collect water quality from a fixed area, and that sedimentation and stratification may occur within the water space, thus affecting the accuracy of sewage sample testing.
