Description

Technical Field

[0001] The utility model relates to the technical field of liquid detection, in particular to an integrated filtering detection device. Background Art

[0002] The application of online water quality detection devices is becoming increasingly widespread. In different application scenarios, the operation of the devices is greatly affected by water quality fluctuations, generally affected by color, turbidity, and bubbles.

[0003] To ensure the stability of on-site online water quality detection devices, filters and defoamers are usually installed on the pipes in front of the devices to pre-treat the liquid. The filters reduce the color and turbidity of the liquid, and the defoamers eliminate foam. However, after the foam is eliminated, it will gather into large bubbles. When the large bubbles pass through the detection end of the sensor, they will interfere with the sensor and affect the detection. In addition, the filters, defoamers and sensors are generally installed separately on the pipes, which is inconvenient to clean and maintain. The joints are prone to leakage after cleaning and maintenance.

[0004] Therefore, it is necessary to propose an integrated filtering detection device to solve the above problems. Utility Model Content

[0027] When in use, the liquid to be detected is fed in from the water inlet 10, the liquid level rises continuously and immerses the sensor 4, the liquid is detected by the sensor 4, and finally discharged from the water outlet 9;

[0028] By providing a filter layer 7 to filter the liquid to be detected, the color and turbidity of the liquid to be detected are reduced, thereby reducing the impact of the color and turbidity on the detection accuracy; by providing a defoaming layer 5, foam in the liquid is eliminated, and the foam is gathered to form large bubbles. At the same time, under the guidance of the partition 3, the bubbles move upward from the guide gap, preventing the bubbles from approaching the detection end of the sensor 4 and interfering with the sensor 4. Under their combined action, the detection accuracy of the sensor 4 is ensured;

[0029] In addition, by integrating multiple different sensors 4, it is possible to maintain multiple sensors 4 at the same time, making the operation and maintenance of the sensors 4 more convenient.

The end of the sensor 4 away from the detection barrel 2 extends through the positioning plate 16, and the positioning plate 16 is fixedly connected to the detection barrel 2. Preferably, the positioning plate 16 and the detection barrel 2 are fixedly connected by screws. The positioning plate 16 acts on the retaining ring 14 to limit the position of the sensor 4, preventing the sensor 4 from falling out of the detection barrel 2.

[0035] Specifically, a sealing gasket is provided between the limiting ring 14 and the detection cylinder 2. The limiting ring 14 is pressed by the positioning plate 16, and the sealing gasket cooperates with the limiting ring 14 to seal the interface and prevent liquid leakage.
