Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a monitoring device for urban domestic sewage discharge. Background Technology

[0002] In the process of urban domestic sewage treatment, real-time and accurate monitoring of sewage discharge levels, water quality indicators and impurity content is the core link to ensure the stable operation of the treatment process and achieve compliant discharge.

[0003] Existing devices mostly rely on manual periodic inspections to observe sewage levels, or use mechanical level gauges with delayed response times. These systems cannot track dynamic changes in sewage levels in real time. When the sewage level is too high, the failure to provide timely warnings can easily lead to sewage overflow and secondary pollution of the surrounding environment. Conversely, when the level is too low, the failure to adjust the influent flow in time can result in insufficient water intake for subsequent treatment units (such as biological reaction tanks), affecting treatment efficiency. Furthermore, manual inspection significantly increases labor costs and management loopholes. Therefore, we provide a monitoring device for urban domestic sewage discharge. Utility Model Content

It solves the technical problems of existing urban domestic sewage monitoring devices that rely on manual periodic inspections or mechanical level gauges with delayed responses, which cannot track the liquid level in real time, easily leading to sewage overflow or affecting treatment efficiency, increasing labor costs and management loopholes. The device achieves the ability to track the sewage level in real time and transmit relevant data in real time, improving the monitoring efficiency of sewage and reducing labor costs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a monitoring device for urban domestic sewage discharge, comprising a treatment box with an inlet pipe and an outlet pipe installed on both sides respectively.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 To address the problems of existing urban domestic sewage monitoring devices relying on manual periodic inspections or mechanical level gauges with delayed responses, which cannot track liquid levels in real time and are prone to sewage overflow or reduced treatment efficiency, increasing labor costs and management loopholes, this embodiment provides an urban domestic sewage discharge monitoring device capable of tracking sewage levels in real time and transmitting relevant data in real time, improving sewage monitoring efficiency and reducing labor costs. Please refer to... Figure 1 - Figure 6 The town's domestic sewage discharge monitoring device includes a treatment box 1 with an inlet pipe and an outlet pipe installed on both sides.

[0019] Existing urban domestic sewage monitoring devices mostly rely on manual periodic inspections to observe sewage levels, or use mechanical level gauges with slow response times, which cannot track dynamic changes in the level in real time. In addition, the manual inspection mode increases labor costs. In order to solve the above problems...

[0020] Inside the processing tank 1, a marker rod 2 is slidably connected in the middle. A float seat 3 is installed at the bottom of the marker rod 2, and a marker sensor 4 and position sensors 5 distributed on both sides of the marker sensor 4 are installed at its top. An L-rod 6 is installed at the top of the processing tank 1. The top of the L-rod 6 has round holes that are distributed directly above the marker rod 2 and adapted to it, forming a rigid guide channel. The horizontal deviation of the marker rod 2 is eliminated by physical limiting, ensuring that the marker sensor 4 and the position sensor 8 are accurately aligned. This avoids warning delays or false alarms caused by the shaking of the top when the liquid level fluctuates. Multiple sets of supports 7 are installed inside the L-rod 6 to keep the marker rod 2 stable. The multiple sets of supports 7 are on the same vertical plane as the marker rod 2, forming a distributed vertical support system to prevent the marker rod 2 from tilting. Together with the round holes, they ensure the accuracy of its vertical movement throughout its entire stroke and ensure the effectiveness of sensor data transmission. A position sensor 8 connected to the marker sensor 4 is installed on the upper inside of the L-rod 6. An alarm 9 connected to the position sensor 8 is installed at the top of the processing tank 1 corresponding to the water inlet pipe, so that an alarm can be issued when the marker rod 2 exceeds the reasonable position.

[0021] Water enters through an inlet pipe and exits through an outlet pipe on both sides of the treatment tank 1. When the water level inside the treatment tank 1 rises, the float 3, which has a lower density than water, will float upwards as the sewage level rises. This causes the marker rod 2 to rise smoothly along the support 7. The marker sensor 4 and position sensor 5 at the top of the marker rod 2 move synchronously with it. When the marker sensor 4 touches the position sensor 8 on the inner side of the L rod 6, the position sensor 8 will trigger the alarm 9 at the inlet pipe at the top of the treatment tank 1 to issue a warning, thereby alerting the staff that there is too much sewage. In addition, the position sensor 5 transmits the value of the rise and fall of the marker rod 2 to the PLC control terminal in real time, improving the monitoring and management efficiency of sewage discharge.

[0022] Inside the treatment tank 1, a filter screen 10 is slidably installed at the outlet pipe. A waterproof motor 11 is installed at the top of the treatment tank 1, distributed beside the filter screen 10. Connecting rods 12, distributed inside the treatment tank 1, are installed on the output shaft of the waterproof motor 11. Several sets of agitator blades, distributed below the fixed square cylinder 13, are installed on the connecting rods 12. These blades can pre-crush larger impurities in the wastewater, preventing large particles from directly accumulating on the surface of the filter screen 10 and causing blockage. This clears obstacles for subsequent filtration operations of the filter screen 10, ensuring efficient wastewater flow. Several sets of downward-extending fixed square tubes 13 are installed on the rod 12. Each set of fixed square tubes 13 has a vibrating element 14 slidably connected inside. The contact end between the vibrating element 14 and the filter screen 10 is an arc-shaped structure, which can avoid the vibrating element 14 from scratching and wearing the filter screen 10, extend the service life of the filter screen 10, and at the same time make the contact between the vibrating element 14 and the filter screen 10 more uniform, ensuring the vibration and impurity removal effect, and further preventing impurities from adhering to the filter screen 10 and affecting the filtration performance. The vibrating element 14 and the inside of the fixed square tube 13 are connected by a connecting spring 15.

[0023] A filter screen 10 is inserted into the top of the treatment tank 1 at the outlet pipe and fixed with bolts. This can filter some impurities in the sewage. When the waterproof motor 11 is working, it drives the connecting rod 12 inside the treatment tank 1 to rotate, which in turn causes the fixed square tube 13 to rotate synchronously. Due to the inertia generated by the rotation, the connecting spring 15 is deformed, which causes the vibrating element 14 to slide. Under the elastic action of the connecting spring 15, the filter screen 10 is continuously vibrated to prevent clogging. The agitator on the connecting rod 12 can also help to agitate impurities and ensure the smooth discharge of sewage.

[0024] Example 2 Based on Example 1, such as Figure 1 - Figure 6 As shown, existing urban domestic sewage monitoring devices rely on manual periodic inspections or mechanical level gauges with delayed response, which cannot track the liquid level in real time, easily leading to sewage overflow or affecting treatment efficiency, increasing labor costs and management loopholes. However, existing water quality monitoring equipment is mostly limited to monitoring a single indicator, making it difficult to obtain multiple water quality parameters at the same time and to determine the degree of sewage pollution. Therefore, this device is also equipped with a structure that can monitor multiple data at the same time.

[0025] Existing water quality monitoring equipment is mostly limited to monitoring a single indicator, making it difficult to obtain multiple water quality parameters simultaneously. This makes it impossible to comprehensively and accurately determine the degree of sewage pollution, causing inconvenience to sewage treatment assessment. In order to solve the above problems...

[0026] Inside the treatment tank 1, at the bottom corresponding to the inlet pipe, a ground rail 16 is installed. A mounting frame 17 is slidably connected to the ground rail 16. The mounting frame 17 is fixed to the treatment tank 1 with bolts, providing a stable mounting foundation for the pH monitor 20, dissolved oxygen monitor 21, and COD / BOD monitor 22. This prevents the monitors from shifting or shaking due to unstable installation during sewage flow or device operation, ensuring a constant monitoring position and guaranteeing the accuracy of water quality monitoring data. It also facilitates the replacement of the three devices. A control electric actuator 18 is installed at the outer end of the mounting frame 17. A mounting extension 19 is installed at the telescopic end of the control electric actuator 18. 9. From top to bottom, a pH monitor 20, a dissolved oxygen monitor 21, and a COD / BOD monitor 22 are installed in sequence via threads. These monitors can simultaneously monitor multiple values ​​in wastewater in real time. The pH monitor 20, dissolved oxygen monitor 21, and COD / BOD monitor 22 are wirelessly connected to an external PLC controller. This allows for the timely transmission of key water quality data, such as the real-time monitored wastewater pH value, dissolved oxygen content, and COD / BOD value, to the PLC controller. This enables centralized data reception and processing, facilitating remote and real-time monitoring of wastewater quality by staff and providing accurate data support for subsequent optimization of wastewater treatment solutions.

[0027] Before monitoring the wastewater, the bottom of the mounting frame 17 is attached to the ground rail 16, and the mounting frame 17 is pushed so that the installed monitors are distributed inside the treatment box 1. The mounting frame 17 is then fixed with bolts. The control electric push rod 18 at the outer end of the mounting frame 17 can drive the mounting base 19 to adjust its position, making it easy to adjust the monitoring position within a certain range. Multiple indicators of wastewater can be monitored in real time through the pH monitor 20, dissolved oxygen monitor 21, and COD / BOD monitor 22. All three are wirelessly connected to an external PLC controller, which can transmit the monitored data in real time, thus improving the efficiency of wastewater monitoring.
