Description

Technical Field

[0001] This utility model mainly relates to the field of sewage treatment equipment technology, specifically a dosing device for sewage treatment with monitoring function. Background Technology

[0002] Wastewater treatment equipment refers to mechanical equipment and systems used to treat wastewater to meet discharge or reuse standards. This equipment is widely used in urban wastewater treatment plants, industrial wastewater treatment, municipal wastewater treatment, and rural wastewater treatment, aiming to reduce wastewater pollution and protect water resources and the ecological environment.

[0003] In existing wastewater treatment equipment, the water level is usually manually observed when adding wastewater to the treatment tank, and then the stirring height is adjusted and stirred. This method increases the workload of manual labor and has a low degree of automation. Secondly, existing water quality monitoring devices can usually only monitor a limited number of indicators, such as pH value and COD, and lack real-time monitoring of the residual concentration of chemicals. This makes it impossible to adjust the dosage in time, which may lead to excessive or insufficient dosage, affecting the treatment effect and cost. Utility Model Content

[0004] This utility model mainly provides a wastewater treatment dosing device with monitoring function to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A wastewater treatment dosing device with monitoring function includes a box, a drain outlet is provided on one side of the inner wall of the box, a detection mechanism is provided on the outside of the drain outlet, a first motor is fixedly installed on the top of one side of the box, a moving mechanism is provided at the top inside the box, and a limiting mechanism is provided on one side of the moving mechanism at the top inside the box. Mounting plates are fixedly installed on both sides of the box, and a dosing mechanism is fixedly installed on the top of each of the two mounting plates.

[0006] Preferably, the detection mechanism includes a water quality detection sensor and a chemical residue monitoring sensor. The water quality detection sensor is fixedly installed on one side of the drain outlet, and the chemical residue monitoring sensor is fixedly installed on the side of the drain outlet away from the water quality detection sensor.

[0007] Preferably, the moving mechanism includes a threaded rod and a moving block. The threaded rod is connected to the top of the inside of the housing via a rotating shaft, and one end of the threaded rod is connected to the output shaft of the first motor. The moving block is connected to the outer side of one end of the threaded rod via a thread.

[0008] Preferably, the limiting mechanism includes a limiting rod and a limiting block. The limiting rod is fixedly connected to the top of the inside of the housing on one side of the moving mechanism, and the limiting block is movably connected to the outer side of one end of the limiting rod through a mounting hole.

[0009] Preferably, both the moving block and the limiting block are fixedly connected to an electric push rod at their bottoms, and the bottom of the electric push rod is fixedly connected to a connecting strip, and multiple second motors are fixedly installed at the bottom of the connecting strip, and a stirring rod is connected to the output shaft end of the second motor.

[0010] Preferably, three non-contact water level monitors are fixedly installed on the outside of the housing, and all three non-contact water level monitors are electrically connected to a signal controller.

The metering pump is fixedly installed on the top of both mounting plates, and the storage tank is fixedly installed on the top of one side of the metering pump, and the dosing pipeline is fixedly installed on the bottom of one side of the metering pump.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By using metering pumps and non-contact water level monitors, precise control of the dosage of chemicals and dynamic adjustment of the stirring height are achieved. During use, the metering pump controls the dosage of chemicals according to the preset dosing ratio and sewage flow rate, ensuring an appropriate ratio of chemicals to sewage. At the same time, the non-contact water level monitor monitors the water level in real time and transmits the signal to the signal controller. The controller automatically adjusts the extension length of the electric push rod according to the water level, driving the stirring rod to move to the appropriate stirring height. This avoids uneven stirring caused by water level changes, ensuring that the chemicals and sewage can be fully mixed, significantly improving the efficiency and quality of sewage treatment. There is no need for manual observation of the water level. By driving the first and second motors, the stirring rod can stir at different positions, further improving the mixing effect and ensuring the uniformity and efficiency of sewage treatment. Real-time monitoring of treated water quality is achieved through water quality detection sensors and chemical residue monitoring sensors. The water quality detection sensors can monitor key indicators such as pH value, COD (chemical oxygen demand), and BOD (biochemical oxygen demand) of wastewater in real time, ensuring that the treated water quality meets the discharge standards. The chemical residue monitoring sensors can detect the concentration of residual chemicals in wastewater and feed the data back to the control system. The control system automatically adjusts the dosage based on the monitoring data to ensure that the amount of chemicals added meets the treatment requirements while avoiding waste.

Detailed Implementation

[0015] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0016] Please refer to the appendix carefully. Figure 1-5A wastewater treatment dosing device with monitoring function includes a housing 1. A drain outlet 2 is provided on one side of the inner wall of the housing 1 for discharging treated wastewater. A detection mechanism 3 is provided on the outside of the drain outlet 2. The detection mechanism 3 includes a water quality sensor 301 and a chemical residue monitoring sensor 302. The water quality sensor 301 is fixedly installed on one side of the drain outlet 2 to monitor key water quality indicators such as pH, COD, and BOD of the wastewater. The chemical residue monitoring sensor 302 is fixedly installed on the side away from the water quality sensor 301 to monitor the concentration of residual chemicals in the wastewater. Data from both the water quality sensor 301 and the chemical residue monitoring sensor 302 are fed back to the control system to ensure the treated wastewater is properly regulated. The water meets the discharge standards, and a first motor 4 is fixedly installed on the top side of one side of the tank 1. A moving mechanism 5 is located at the top inside the tank 1. The moving mechanism 5 includes a threaded rod 501 and a moving block 502. The threaded rod 501 is connected to the top inside the tank 1 via a rotating shaft, and one end of it is connected to the output shaft of the first motor 4. The moving block 502 is threadedly connected to the outer side of one end of the threaded rod 501. The moving block 502 can move axially under the rotation of the threaded rod 501. Simultaneously, a limiting mechanism 6 is located on one side of the moving mechanism 5 at the top inside the tank 1. The limiting mechanism 6 includes a limiting rod 601 and a limiting block 602. The limiting rod 601 is fixedly connected to the top inside the tank 1 on one side of the moving mechanism 5, and one end of the limiting rod 601... A limiting block 602 is movably connected to the outer side via mounting holes. The limiting block 602 restricts the movement range of the moving block 502, ensuring its smooth movement within a predetermined track. Electric push rods 9 are fixedly connected to the bottom of both the moving block 502 and the limiting block 602. A connecting strip 10 is fixedly connected to the bottom of the electric push rod 9, and multiple second motors 11 are fixedly installed at the bottom of the connecting strip 10. There are seven second motors 11. The output shaft of each second motor 11 is connected to a stirring rod 12. The stirring rod 12 moves up and down inside the tank 1 through the extension of the electric push rod 9, ensuring thorough mixing of the reagent and wastewater. Mounting plates 7 are fixedly installed on both sides of the tank 1, and dosing mechanisms 8 are fixedly installed on the top of both mounting plates 7. Mechanism 8 includes a metering pump 801, a storage tank 802, and a dosing pipe 803. The metering pump 801 is fixedly installed on the top of both mounting plates 7, and the storage tank 802 is fixedly installed on the top of one side of the metering pump 801. The dosing pipe 803 is fixedly installed on the bottom of one side of the metering pump 801. Three non-contact water level monitors 13 are fixedly installed on the outside of the tank 1, which can monitor the water level inside the tank 1 in real time. The three non-contact water level monitors 13 are electrically connected to a signal controller 14. The signal controller 14 controls the extension length of the electric push rod 9 according to the data fed back by the non-contact water level monitors 13, thereby automatically adjusting the height of the stirring rod 12 according to the water level to ensure the optimal stirring effect.

[0017] The specific operation method of this utility model is as follows: During use, the amount of chemical added is controlled by the metering pump 801 based on the preset dosing ratio and sewage flow rate, and falls into the tank 1 through the dosing pipe 803. At this time, the non-contact water level monitor 13 can monitor the water level and transmit the signal to the signal controller 14, which in turn controls the extension of the electric push rod 9 to move the stirring rod 12 to a suitable stirring height. This avoids uneven mixing of sewage and chemical due to the inability to adjust the stirring height according to the water level. Then, the first motor 4 is driven, causing its output shaft to rotate the threaded rod 501. The moving block 502 reciprocates on the bolt rod to prevent the stirring position from being fixed. At this time, the second motor 11 is driven to drive the stirring rod 12 to stir, so that the sewage and the agent can be mixed more quickly. After the sewage treatment is completed, it can be discharged through the drain outlet 2. The water quality detection sensor 301 can monitor key indicators such as pH value, COD chemical oxygen demand, and BOD biochemical oxygen demand of sewage to ensure that the treated water quality meets the standards. The agent residue monitoring sensor 302 can detect the concentration of residual agents in sewage and feed the data back to the control system for adjusting the dosage.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
