Description

Technical field:

[0001] The utility model relates to an underwater sensor flushing device for sewage treatment, in particular to a sensor cleaning for water quality monitoring and measurement in the sewage treatment process, belonging to the technical field of environmentally friendly sewage treatment. Background technology:

[0002] Industrial production and human social activities will generate a large amount of sewage. Especially in the process of industrialization and urbanization, it is necessary to build and equip sewage treatment plants of corresponding number and scale to reduce pollution to the human living environment. At present, urban sewage treatment in my country has become a huge industry.

[0003] In the sewage treatment process, water quality parameters need to be continuously measured by water quality analysis sensors. Water quality analysis sensors are generally installed at the lower end of the measuring rod. The upper part of the measuring rod is fixed by the sensor bracket, and the lower part is immersed in the sewage treatment pool. Many sensors use optical detection to detect data, such as dissolved oxygen, turbidity and other instruments. Since there are many mixtures in the sewage that contaminate the probe, the sensor probe must be cleaned manually frequently, otherwise the detection value will be inaccurate. Summary of the invention:

[0004] The utility model aims to provide a device which can automatically and regularly clean the sensor probe in view of the drawbacks of the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a flushing device for an underwater sensor for sewage treatment, which consists of a fixed mounting bracket, a solenoid valve, an air pipe and a flushing nozzle assembly. The air pipe is mounted on a measuring rod of a vertically arranged sensor through the fixed mounting bracket, the solenoid valve is mounted in the middle of the air pipe, the air outlet at the bottom end of the air pipe is mounted with the flushing nozzle assembly, the air inlet at the top is connected to an air supply network, the flushing nozzle assembly is communicated with the air pipe, and the flushing nozzle assembly is bent upward to align with an optical measuring window below the probe of the sensor.

[0007] The fixed installation brackets are arranged in two groups up and down, and each group is arranged with two brackets up and down.

[0008] The flushing nozzle assembly includes a base and a nozzle. One end of the base is connected to the air outlet of the trachea, and the other end is connected to the nozzle. The nozzle is made by bending a hollow steel pipe. One end of the hollow steel pipe connected to the base is provided with a connecting thread, and the other end is bent upward to align with the optical measurement window under the probe of the sensor. The hollow part inside the hollow steel pipe is an internal airflow channel.

[0009] The material of the flushing nozzle assembly is stainless steel; the material of the air pipe is stainless steel or rubber pipe.

[0010] The fixed mounting bracket includes two flat steels and fixing bolts. The flat steel is galvanized 40x4 flat steel, and the fixing bolts are galvanized M8 bolts. The flat steel is provided with a semicircle matching the diameter of the air pipe and the measuring rod. The flat steel is provided with a through hole matching the fixing bolt. The two flat steels are arranged opposite to each other, and the air pipe is fixed to the measuring rod of the sensor by the fixing bolts.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the prior art, when it is necessary to clean the probe of the sensor for water quality monitoring, the sensor needs to be removed from the wall of the pool. After the cleaning work is completed, the sensor needs to be reinstalled on the wall of the pool. The workload is large and the task is cumbersome. However, the utility model is connected to the measuring rod of the sensor. When the sensor needs to be cleaned, it is only necessary to open the solenoid valve for ventilation, so that the flushing nozzle assembly forms an airflow to flush the sensor surface. The flushing nozzle flushes out gas and sprays it to the optical detection window of the sensor probe for cleaning. The workload is greatly reduced, the waste of manpower and material resources is reduced, time is saved, and work efficiency is improved.

[0013] 2. The utility model has a simple and reasonable structure, low cost and is easy to implement, easy to operate and has a good cleaning effect.

[0014] 3. The utility model can realize automatic or timed flushing of the sensor probe to ensure normal detection of the sensor probe.

[0015] 4. The utility model can avoid the trouble of manual cleaning of the sensor and prevent the risk of people falling into the pool. Description of the drawings:

The air pipe 4 is mounted on a measuring rod 7 of a vertically arranged sensor 5 through a plurality of fixed mounting brackets 3. In this embodiment, two groups of fixed mounting brackets 3 are arranged in the upper and lower parts, and two are arranged in each group in the upper and lower parts. The flushing nozzle assembly 1 is installed at the air outlet at the bottom of the air pipe 4, and the air inlet at the top is connected to the air supply network. The flushing nozzle assembly 1 is connected to the air pipe 4, and the flushing nozzle assembly 1 is bent upward to align with the optical measurement window below the probe 6 of the sensor 5. The solenoid valve 2 is installed in the middle of the air pipe 4, and the gas is controlled by the solenoid valve 2 to flush the probe 6 of the sensor 5.

The flat steel 3.1 is made of galvanized 40x4 flat steel, and the fixing bolts 3.2 are made of galvanized M8 bolts. The flat steel 3.1 is provided with a semicircle that matches the diameter of the air pipe 4 and the measuring rod 7.
