Description

Technical Field

[0001] The utility model relates to an online instrument cleaning system for sewage treatment, belonging to the technical field of sewage treatment. Background Art

[0002] Sewage treatment plants or enterprise-supported sewage treatment stations are equipped with online instruments such as pH, DO, ORP, MLSS, fluoride ions, conductivity, and temperature as needed. Operation and maintenance personnel use online detection data changes to determine the operating status of the wastewater treatment system and adjust the sewage treatment operating parameters to ensure the normal operation of the wastewater treatment facilities and that the effluent meets the discharge standards. These online detection instrument probes are installed in the wastewater. Due to corrosion, scaling, or sludge and impurity deposition in the wastewater, the online monitoring equipment needs to be cleaned regularly to ensure the accuracy of the monitoring data.

[0003] At present, sewage treatment plants or sewage treatment stations have two ways of cleaning the probes of online monitoring equipment. One is to manually take out the probes regularly for cleaning and then install them back in place after cleaning. This method is time-consuming, labor-intensive and labor-intensive. The other is to wash the probes with water aligned with the pipeline and then use ultrasonic vibration to clean the probes. This cleaning method usually requires each probe to be additionally equipped with an ultrasonic cleaning head and a high-pressure water cleaning head. It has a complex structure, high installation cost and is difficult to maintain. In addition, ultrasonic cleaning may cause a certain degree of interference or damage to the internal components of the probe, resulting in a shortened life of the equipment.

[0004] A sewage online detection instrument probe cleaning device is disclosed in a Chinese utility model patent with publication number CN217664910U, which includes a water pool and a detection probe. The detection probe is located in the water pool. A guide rod mounting frame is installed on the top of the inner cavity of the water pool. A first mounting guide rod and a cleaning water pipe are respectively installed on the guide rod mounting frame. An ultrasonic cleaning device is installed at one end of the first mounting guide rod. The ultrasonic cleaning device is electrically connected to an electrical control cabinet through wires. A cleaning nozzle is connected to one end of the cleaning water pipe, and the cleaning nozzle is located directly below the detection probe and faces the detection probe. One end of the cleaning water pipe is connected to an external cleaning water tank relative to the other end.

[0005] In the above reference example, each probe needs to be equipped with an ultrasonic cleaning device and a cleaning water pipe. The structure is redundant and complex, and ultrasonic cleaning consumes a lot of energy and is costly. It is not suitable for cleaning a large number of probes in sewage treatment plants or sewage treatment stations, so improvement is urgently needed. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A sewage treatment online instrument cleaning system comprises a cleaning pipeline, a cleaning nozzle and an instrument body, and also comprises an alkali cleaning tank, an acid cleaning tank and a clean water tank which are arranged in parallel with each other, wherein the output ends of the alkali cleaning tank, the acid cleaning tank and the clean water tank are all connected to a merging pipeline, and the output end of the merging pipeline is connected to the cleaning pipeline through a pumping pipeline, and a plurality of cleaning branch pipes are connected to the cleaning pipeline, and the output end of each cleaning branch pipe is connected to a cleaning nozzle, and each of the cleaning nozzles is installed on a plurality of the instrument bodies in a one-to-one correspondence.

The instrument connecting rod is connected to a rotating mechanism, and an arc-shaped water storage box is installed on the rotating mechanism. The arc-shaped water storage box is connected to a plurality of nozzles on one side close to the instrument probe.

[0011] Furthermore, the rotary mechanism includes a driving motor, a rotating shaft, a driving gear and a driven gear. The driving gear is transmission-connected to the driving motor via the rotating shaft. The driven gear is meshed with the driving gear and the driven gear is rotatably sleeved on the instrument connecting rod. The arc-shaped water storage box is fixed at the bottom end of the driven gear.

DETAILED DESCRIPTION

[0026] The present invention will be described in more detail below in conjunction with the embodiments.

[0027] See also Figure 1 , Figure 2 and Figure 3 The sewage treatment online instrument cleaning system of this embodiment includes a cleaning pipeline 22, a cleaning nozzle 9 and an instrument body 10, and also includes an alkali cleaning tank 4, an acid cleaning tank 5 and a clean water tank 6 arranged in parallel with each other, and the output ends of the alkali cleaning tank 4, the acid cleaning tank 5 and the clean water tank 6 are all connected to a confluent pipeline 21. Specifically, valves are arranged between the alkali cleaning tank 4, the acid cleaning tank 5 and the clean water tank 6 and the confluent pipeline 21;

[0028] In this embodiment, the meter body 10 includes a meter display screen 11, a meter connecting rod 18 fixed to the lower end of the meter display screen 11, and a meter probe 20 fixed to the bottom end of the meter connecting rod 18. The meter probe 20 is arranged inside the sewage, and the meter display screen 11 is arranged at the upper end of the sewage.

[0029] The output end of the merging pipeline 21 is connected to the cleaning pipeline 22 through the pumping pipeline 23. The cleaning pipeline 22 is connected to a plurality of cleaning branch pipes 8. The output end of each cleaning branch pipe 8 is connected to a cleaning nozzle 9. Each cleaning nozzle 9 is installed one by one on a plurality of instrument bodies 10. The cleaning nozzle 9 is used to clean the instrument probe 20.

[0030] As can be seen from the above description, the beneficial effect of the utility model is that, through the alkaline cleaning box 4, the acid cleaning box 5 and the clean water tank 6 arranged in parallel with each other, a suitable cleaning box can be selected according to the specific contamination condition of the instrument probe 20. For example, scaling caused by hardness can be restored to normal by acid cleaning. For example, scaling caused by sludge deposition in the biochemical system can be restored to normal by flushing the sludge with clean water. When affected by acidic substances or organic substances, it can be restored to normal by alkaline cleaning. The combination of the three cleaning methods can be applied to a variety of cleaning conditions and is more suitable for the complex and changeable water quality conditions in sewage treatment plants or sewage treatment stations. In addition, compared with ultrasonic cleaning, the setting of the alkaline cleaning box 4, the acid cleaning box 5 and the clean water tank 6 makes the cleaning of the instrument probe 20 more gentle, does not cause damage to the inside of the instrument probe 20, and prolongs the service life of the instrument probe 20.

[0031] At the same time, by installing the cleaning nozzle 9 on the instrument body 10, installation and maintenance are relatively convenient, and with the setting of the merging pipeline 21, the cleaning pipeline 22 and the cleaning branch pipe 8, multiple instrument probes 20 can be cleaned at the same time, which greatly improves the cleaning efficiency of the instrument probe 20 and can well ensure the cleaning effect.

[0032] Furthermore, it also includes a reflux pipeline 3, one end of which is connected to the free end of the cleaning pipeline 22, and the other end of which is respectively connected to the alkaline cleaning tank 4, the acid cleaning tank 5 and the clean water tank 6, and a control valve is provided between the reflux pipeline 3 and the alkaline cleaning tank 4, the acid cleaning tank 5 and the clean water tank 6;

[0033] Specifically, the control valve includes a control valve 1 and a control valve 2 which are connected in series. The control valve 1 is an automatic valve, the control valve 2 is a manual valve, and the control valve 1 is arranged at the downstream position of the control valve 2.

[0034] From the above description, it can be seen that the setting of the return pipeline 3 can recycle excess cleaning liquid or water, reduce waste, and allow the cleaning liquid to flow back into the corresponding cleaning box to prevent corrosion to the pipeline, while also improving energy utilization.

[0035] For further information, see Figure 2 and Figure 3 The instrument connecting rod 18 is connected to a rotary mechanism, and an arc-shaped water storage box 16 is installed on the rotary mechanism. The arc-shaped water storage box 16 is connected to a plurality of nozzles 17 on one side close to the instrument probe 20. The setting of the arc-shaped water storage box 16 facilitates the spray cleaning of the instrument probe 20;

[0036] Specifically, the rotary mechanism includes a driving motor 13, a rotating shaft 14, a driving gear 15 and a driven gear 19. The driving gear 15 is connected to the driving motor 13 through the rotating shaft 14. The driven gear 19 is meshed with the driving gear 15 and the driven gear 19 is rotatably sleeved on the instrument connecting rod 18. The arc-shaped water storage box 16 is fixed at the bottom end of the driven gear 19.

[0037] From the above description, it can be seen that when the driving motor 13 is started, the rotating shaft 14 is driven to rotate. The rotation of the rotating shaft 14 will drive the driving gear 15 to rotate, and then the driven gear 19 is driven to rotate through the driving gear 15. During the rotation of the driven gear 19, the arc-shaped water storage box 16 will be driven to rotate around the instrument probe 20, thereby cleaning the instrument probe 20 in all directions, effectively improving the cleaning effect of the instrument probe 20.

[0038] Furthermore, the driving motor 13 is fixedly connected to the instrument connecting rod 18 via the connecting frame 12 .

[0039] Furthermore, the pumping pipeline 23 includes two cleaning pumps 7 connected in parallel, and valves are provided at both ends of each cleaning pump 7. One of the two cleaning pumps 7 is spare to improve the stability of system operation and prevent the cleaning pump 7 from being shut down for maintenance.

[0040] Furthermore, each cleaning branch pipe 8 is provided with a valve.

[0041] Furthermore, the connection points of the alkaline cleaning tank 4 , the acid cleaning tank 5 and the clean water tank 6 with the merging pipeline 21 are arranged close to the cleaning pipeline 22 in sequence.

[0042] Working principle of the utility model: During the cleaning process, by selecting a suitable cleaning tank and controlling the flow and pressure of the cleaning liquid in the alkaline cleaning tank 4, the acid cleaning tank 5 or the clean water tank 6, the cleaning liquid is output to the cleaning pipeline 22 through the confluence pipeline 21, and a plurality of cleaning branch pipes 8 connected to the cleaning pipeline 22 will divert the cleaning liquid to each instrument body 10, and each instrument body 10 corresponds to a cleaning nozzle 9, and then the cleaning liquid is sprayed onto the surface of the instrument probe 20 through the cleaning nozzle 9 to clean and remove the dirt on the surface;

[0043] The design of the reflux pipeline 3 allows the cleaning liquid to reflux during the flow process, thereby ensuring the recycling of the cleaning liquid in the cleaning pipeline 22 and saving the consumption of the cleaning liquid.
