Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular, it is a monitoring and alarm device for the outlet of an industrial wastewater treatment plant. Background Technology

[0002] With the acceleration of industrialization, the discharge of industrial wastewater is increasing day by day. Its complex composition and diverse pollutants pose a serious threat to the environment. In order to protect the ecological environment and human health, governments around the world have introduced strict environmental regulations, requiring industrial enterprises to effectively treat the wastewater generated during production processes to ensure that the discharged water quality meets the prescribed standards.

[0003] However, existing industrial wastewater treatment technologies and equipment face numerous challenges in practical applications. For example, many wastewater treatment plants employ a single drainage pipeline design, meaning that if a malfunction occurs or maintenance is required at any point, the entire system must cease operation. This not only disrupts normal production but may also lead to the illegal discharge of untreated or incompletely treated wastewater, causing environmental pollution. The single discharge path design ensures that any malfunction will cause the entire system to shut down, severely impacting continuous production and wastewater treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring and alarm device for the outlet of an industrial wastewater treatment plant to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a monitoring and alarm device for the outlet of an industrial wastewater treatment plant, comprising a wastewater treatment tank, an inlet pipe connected to the upper part of one side of the wastewater treatment tank, and a drain pipe connected to the lower part of the other side of the wastewater treatment tank. The drain pipe is sealed with a T-shaped branch main pipe by flanges and bolts. At least two branch drain pipes are equidistantly connected to the side of the branch main pipe away from the drain pipe. A transition secondary filter pipe is sealed to the end of each branch drain pipe away from the branch main pipe. A tertiary filter pipe is sealed to the end of the transition secondary filter pipe away from the branch drain pipe. A solenoid valve is installed inside the end of each branch drain pipe near the branch main pipe. A contact monitoring instrument is inserted into one side of the solenoid valve and on the side of each branch drain pipe away from the branch main pipe. An impurity sedimentation chamber is connected to the bottom of the end of each branch drain pipe near the transition secondary filter pipe. A first activated carbon filter screen is installed inside the end of the transition secondary filter pipe near the branch drain pipe.

[0006] In a preferred embodiment, the branch drain pipe is integrally connected to a second external threaded pipe at the end furthest from the main branch pipe. The second external threaded pipe is threadedly connected to the transition secondary filter pipe, and the first activated carbon filter is embedded and fixed in the inner cavity of the transition secondary filter pipe near the branch drain pipe.

[0007] In a preferred embodiment, the inner wall of the transition secondary filter tube away from the branch drain pipe is provided with an internal thread, and the end of the tertiary filter tube near the transition secondary filter tube is integrally connected with a first external thread tube, and the internal thread and the first external thread tube are threaded together.

[0008] In a preferred embodiment, a second activated carbon filter screen is embedded and fixed in the inner cavity of the end of the three-stage filter tube closest to the first external threaded tube, and a filter element column is embedded and fixed in the inner cavity of the end of the three-stage filter tube furthest from the first external threaded tube.

[0009] In this preferred embodiment, the contact monitor has a monitoring probe at one end that is plugged into the branch drain pipe, and an alarm is installed at the top of the contact monitor, which includes a buzzer and an alarm light.

[0010] In this preferred embodiment, a slag discharge pipe is connected through the bottom of each impurity sedimentation chamber, and a sealing cap is threaded to the bottom end of each slag discharge pipe.

[0011] In a preferred embodiment, a preliminary filter screen is fixedly mounted on the upper part of the inner cavity of the wastewater treatment tank. The first and second activated carbon filters are used to remove odors, and the filter cartridge is used for final filtration of impurities.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This monitoring and alarm device for the effluent outlet of an industrial wastewater treatment plant features a branch drainage pipe design that allows for water quality monitoring or filter replacement without halting drainage. When an anomaly is detected in a branch drainage pipe, a solenoid valve automatically closes that path, while other branch drainage pipes continue to operate normally. This prevents the entire system from shutting down due to a single point of failure, significantly improving the operating efficiency and reliability of the wastewater treatment plant. Because filter replacement and equipment maintenance can be performed in batches without interrupting the entire discharge process, economic losses due to downtime are reduced, and maintenance costs are also lowered.

[0014] The linkage mechanism between the contact-type monitoring instrument and the PLC can detect water quality anomalies immediately and take immediate measures (such as closing the corresponding solenoid valves) to prevent the discharge of substandard wastewater. This real-time feedback mechanism not only protects the environment but also complies with stringent environmental regulations. The automated control system reduces reliance on manual monitoring, lowers the workload of operators, and improves the accuracy and timeliness of monitoring.

[0015] From the primary filter screen to the first activated carbon filter screen in the secondary filter tube, and then to the second activated carbon filter screen and filter cartridge in the tertiary filter tube, a highly efficient multi-stage filtration system is formed. Each stage of filtration targets specific types of pollutants, ensuring that the final discharged water meets high standards. The first and second activated carbon filters are specifically designed to remove odor-causing substances from the water, improving the quality of the discharged water and reducing the impact on the surrounding environment.

[0016] The impurity settling chamber and slag discharge pipe design at the bottom of each branch drain pipe allow for centralized collection and treatment of intercepted impurities, simplifying the cleaning process and improving maintenance efficiency. Effective impurity interception reduces the burden on subsequent filtration equipment, thereby extending their service life and lowering long-term operating costs. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] This embodiment provides, for example Figures 1 to 5 The device shown is a monitoring and alarm device for the outlet of an industrial wastewater treatment plant. It includes a wastewater treatment tank 1, with an inlet pipe 2 penetrating the upper part of one side of the wastewater treatment tank 1 and a drain pipe 4 penetrating the lower part of the other side of the wastewater treatment tank 1. The drain pipe 4 is sealed with a T-shaped branch main pipe 5 via flanges and bolts. At least two branch drainage pipes 6 are equidistantly connected to the side of the branch main pipe 5 away from the drain pipe 4. Each branch drainage pipe 6 has a sealed secondary filter pipe 10 at its end away from the branch main pipe 5. The end of the filter tube 10 away from the branch drain pipe 6 is sealed with a three-stage filter tube 13. Each branch drain pipe 6 is equipped with a solenoid valve 7 at the end near the branch main pipe 5. A contact monitor 8 is inserted through the solenoid valve 7 on the side of each branch drain pipe 6 away from the branch main pipe 5. An impurity sedimentation chamber 14 is connected through the bottom of the end of each branch drain pipe 6 near the transition secondary filter tube 10. A first activated carbon filter screen 15 is installed inside the end of the transition secondary filter tube 10 near the branch drain pipe 6. When the contact monitor 8 on each branch drain pipe 6 detects an abnormality in the water quality flowing through it, the contact monitor 8 sends a signal to the PLC. The PLC then closes the solenoid valve 7, shutting down the branch drain pipe 6. Meanwhile, the other branch drain pipes 6 can continue to operate normally, allowing for water quality monitoring or filter replacement without stopping drainage. When other branch drain pipes 6 also discharge abnormal water, they must be shut down simultaneously via the solenoid valve 7 of that branch drain pipe 6. In addition, the first activated carbon filter 15 in the transition secondary filter pipe 10 intercepts fixed impurities in the water, causing the intercepted impurities to precipitate in the impurity sedimentation chamber 14 for subsequent centralized treatment.

[0028] In this embodiment, the end of the branch drain pipe 6 away from the branch main pipe 5 is integrally connected to a second external threaded pipe 19, the second external threaded pipe 19 is threadedly connected to the transition secondary filter pipe 10, and the first activated carbon filter screen 15 is embedded and fixed in the inner cavity of the transition secondary filter pipe 10 near the branch drain pipe 6.

[0029] In this embodiment, the inner wall of the transition secondary filter tube 10 away from the branch drain pipe 6 is provided with an internal thread 11, and the end of the tertiary filter tube 13 near the transition secondary filter tube 10 is integrally connected with a first external thread tube 12, and the internal thread 11 and the first external thread tube 12 are threaded together.

[0030] In this embodiment, a second activated carbon filter screen 16 is embedded and fixed in the inner cavity of the end of the three-stage filter tube 13 closest to the first external threaded tube 12, and a filter element column 17 is embedded and fixed in the inner cavity of the end of the three-stage filter tube 13 away from the first external threaded tube 12.

[0031] In this embodiment, the contact monitor 8 is connected to one end of the branch drain pipe 6 and has a monitoring probe 20. The top of the contact monitor 8 is equipped with an alarm 9, which includes a buzzer and an alarm light.

[0032] In this embodiment, a slag discharge pipe 18 is connected through the bottom of each impurity sedimentation chamber 14, and a sealing cap is threaded to the bottom end of each slag discharge pipe 18.

[0033] In this embodiment, a preliminary filter screen 3 is fixedly mounted on the upper part of the inner cavity of the wastewater treatment tank 1. The first activated carbon filter screen 15 and the second activated carbon filter screen 16 are used to remove odors, and the filter cartridge 17 is used for the final filtration of impurities.

[0034] Working principle:

[0035] This monitoring and alarm device is used at the outlet of an industrial wastewater treatment plant. Industrial wastewater enters the wastewater treatment tank 1 through the inlet pipe 2. A preliminary filter screen 3 is fixedly mounted on the upper part of the inner cavity of the wastewater treatment tank 1 to intercept larger solid impurities, preventing them from entering the subsequent treatment system and reducing the burden on subsequent filtration equipment. When the wastewater passes through the preliminary filter screen 3, larger suspended solids and particles are intercepted and remain in the wastewater treatment tank 1. The pre-filtered wastewater continues to flow to the drain pipe 4. After flowing out of the drain pipe 4 at the lower side of the wastewater treatment tank 1, the wastewater is sealed to the branch main pipe 5 through flanges and bolts. The branch main pipe 5 has a T-shaped design, with at least two branch drain pipes 6 equidistantly connected on the side away from the drain pipe 4, providing multiple discharge paths for the wastewater.

[0036] Each branch drain pipe 6 is equipped with a solenoid valve 7 inside its end near the main branch pipe 5. A contact monitoring instrument 8 is inserted through the solenoid valve 7 on the side of the branch drain pipe 6 furthest from the main branch pipe 5. This instrument is equipped with a monitoring probe 20 to detect specific parameters in the water flow, such as pH value, chemical oxygen demand (COD), biochemical oxygen demand (BOD), and heavy metal concentration. When the contact monitoring instrument 8 detects an abnormality in the water quality flowing through its branch drain pipe 6, it sends a signal to the programmable logic controller (PLC). The PLC determines whether the water quality exceeds the preset standards. If it does, it immediately closes the corresponding solenoid valve 7 to stop the flow of abnormal water and simultaneously triggers the alarm 9, including a buzzer and an alarm light, to notify the operator.

[0037] Each branch drain pipe 6 is sealed at the end furthest from the main branch pipe 5 with a transitional secondary filter pipe 10, which contains a first activated carbon filter screen 15 for adsorbing and removing odor substances and other organic pollutants from the wastewater. Furthermore, the bottom of the transitional secondary filter pipe 10 near the branch drain pipe 6 is connected to an impurity sedimentation chamber 14, used to collect impurities intercepted by the first activated carbon filter screen 15 for easy centralized cleaning. The end of the transitional secondary filter pipe 10 furthest from the branch drain pipe 6 is sealed with a tertiary filter pipe 13, which includes a second activated carbon filter screen 16 and a filter cartridge 17. The second activated carbon filter screen 16 further removes odors from the wastewater, while the filter cartridge 17 performs final fine filtration, intercepting any remaining small particulate impurities to ensure that the final discharged water quality meets discharge standards.

[0038] Each impurity settling chamber 14 is connected to a slag discharge pipe 18 at its bottom, and each slag discharge pipe 18 is threaded with a sealing cap at its bottom end. When it is necessary to clean impurities, the sealing cap can be opened to discharge the settled impurities through the slag discharge pipe 18, thereby ensuring the normal operation of the system. Due to the use of threaded connection design, such as the connection between the second external threaded pipe 19 and the transition secondary filter pipe 10, and the connection between the internal threaded passage 11 and the first external threaded pipe 12, the components are easy to disassemble and replace, facilitating daily maintenance and repair.

[0039] Even if one or more branch drain pipes 6 are shut off due to abnormal water quality, the other unaffected branch drain pipes 6 can still operate normally, ensuring that the drainage process of the entire system is not interrupted. This not only improves the reliability and stability of the system, but also reduces the total downtime caused by a single failure.

[0040] Once the problem causing the water quality abnormality is resolved, such as by replacing the damaged filter or adjusting the treatment process, the operator can use the PLC to reopen the previously closed solenoid valve 7, restoring the corresponding branch drain pipe 6 to normal operation.
