Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an online water quality detection device. Background Art

[0002] In the process of sewage treatment, in order to check the effect of sewage treatment, various tests need to be performed on it. Among them, water turbidity test and pH value test are very important, especially pH value test has high requirements for stability. Most of the existing water quality tests adopt the method of directly installing the detection instrument on the pipeline for detection. However, when the pipeline flow rate is unstable or air is generated, the measurement result may be inaccurate. Based on this, the utility model proposes an online water quality detection device. Utility Model Content

[0003] The purpose of the utility model is to provide an online water quality detection device to solve the above-mentioned problems.

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

[0005] The utility model discloses an online water quality detection device, comprising a pipeline, wherein an outer side wall of the pipeline is connected to a water diversion pipe, the other end of the water diversion pipe is connected to an online turbidity analyzer, the online turbidity analyzer is connected to a water outlet pipe, the water outlet pipe is connected to a bent pipe, the bent pipe is connected to a straight pipe, and the other end of the straight pipe is connected to a drainage pipe; a vertical pipe and an online pH detector are sequentially arranged on the drainage pipe; the top of the vertical pipe is an open structure.

[0006] Furthermore, a drainage trough is provided below the online pH detector.

[0007] Furthermore, a sealing ring is provided at the connection between the water diversion pipe and the pipeline.

[0008] Furthermore, the diameter of the bent pipe is larger than the diameter of the water outlet pipe.

[0009] Furthermore, the water outlet pipe and the bent pipe are in contact connection.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] Before the utility model online water quality detection device detects the pH value, water first flows from high to low to make its flow smooth, thereby excluding air, and then directly contacts with the air through the vertical pipe to discharge excess air, thereby ensuring the stability of the water flow, and then the pH value is detected by the online pH detector, making the detection result more accurate.

[0015] like Figure 1 As shown, an online water quality detection device includes a pipeline 1, the outer wall of the pipeline 1 is connected to a water diversion pipe 2, the other end of the water diversion pipe 2 is connected to an online turbidity analyzer 3, and the online turbidity analyzer 3 is connected to a water outlet pipe 4.

[0016] The outlet pipe 4 is connected to a bent pipe 5, the diameter of the bent pipe 5 is larger than the diameter of the outlet pipe 4, and the outlet pipe 4 and the bent pipe 5 are in contact and connected. The bent pipe 5 is connected to a straight pipe 7, and the other end of the straight pipe 7 is connected to a drain pipe 8. The purpose of the bent pipe 5 is to allow water to fall from a high place, thereby removing air.

[0017] A vertical pipe 9 and an online pH detector 10 are installed on the drainage pipe 8 in sequence. The top of the vertical pipe 9 is an open structure, so that water and air come into contact with each other to achieve the purpose of exhausting air, thereby ensuring the stability of the water flow and the stability of the detection environment.

[0018] A drainage trough 6 is installed below the online pH detector 10 .

[0019] A sealing ring is installed at the connection between the water diversion pipe 2 and the pipeline 1.

[0020] The action process of the utility model is as follows:

[0021] First, the water in pipeline 1 is tested for turbidity after reaching the online turbidity analyzer 3 from the water inlet pipe 2. After the test is completed, the water enters the bent pipe 5 through the outlet pipe 4, and then flows through the straight pipe 7 and the drain pipe 8 in turn. After the vertical pipe 9 on the bent pipe and the drain pipe 8 is exhausted, the water is finally tested for pH value by the online pH detector 10. After the test is completed, it flows into the drain trough 6.
