Description

Technical Field

[0001] This utility model belongs to the field of water purification technology, and in particular relates to a fully automatic resin deoxygenation device for power plants. Background Technology

[0002] At normal temperature and pressure, water dissolves a certain amount of oxygen, known as dissolved oxygen. For drinking water, a higher concentration of dissolved oxygen indicates better water quality. However, for many industrial water uses, high concentrations of dissolved oxygen can lead to equipment corrosion or a decline in product quality. In power plant water treatment systems, resin deoxygenation devices are one of the key pieces of equipment. Their function is to remove dissolved oxygen from boiler feedwater to prevent corrosion of the boiler and pipelines.

[0003] Over prolonged operation, the deoxygenation capacity of resin gradually decreases. As this capacity declines, the oxygen content in the water increases. However, current resin deoxygenation devices lack detection units, making it impossible to monitor the oxygen content in the filtered water in real time. This can lead to corrosion of equipment and pipelines. Therefore, we offer a fully automated resin deoxygenation device for power plants to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic resin deoxygenation device for power plants. By combining the deoxygenation component and the detection component, it solves the problem that existing deoxygenation devices do not have a detection unit.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a fully automatic resin deoxygenation device for power plants, comprising a filter tank. A deoxygenation component is fixedly connected to the top of the filter tank, and a detection component is fixedly connected to the bottom of one side of the filter tank. The deoxygenation component includes an electric push rod fixedly connected to the surface of the filter tank. A cover plate is fixedly connected to the top of the electric push rod, and a drive motor is fixedly connected to the top of the cover plate. The output shaft of the drive motor extends through to the bottom of the cover plate and is fixedly connected to a stirring rod. A hopper is fixedly connected to one side of the top of the cover plate, and an electromagnetic flow valve is connected to the bottom of the hopper. A screw conveyor is connected to the bottom of one side of the filter tank. The detection component includes a water pump fixedly connected to the bottom of the other side of the filter tank. A support plate is fixedly connected to the bottom of the water pump, and one side of the support plate is fixedly connected to the surface of the filter tank. A placement box is fixedly connected to the top of one side of the support plate. Electric push rods are fixedly connected to both sides of the top of the placement box, and an oxygen content detector is fixedly connected to the bottom of the electric push rods. A storage cylinder is placed at the bottom of the placement box.

[0007] The present invention is further configured such that an inlet pipe is connected to the other side of the top of the cover plate, and an outlet pipe is connected to one side of the bottom of the filter tank. The setting of the inlet and outlet pipes clarifies the connection method between the device and the external water circuit, forming a complete water circulation path, which facilitates docking with the existing water treatment system of the power plant, ensures the smooth output of deoxygenated water, and improves the practicality and compatibility of the device.

[0008] The present invention is further configured such that a support leg is fixedly connected to the bottom of the filter tank, and a guide plate is fixedly connected to the bottom of the inner cavity of the filter tank. The support leg provides stable support for the filter tank and adapts to different installation environments. The inclined design of the guide plate guides the water flow to the outlet, reduces water accumulation and resin buildup at the bottom, improves the utilization rate of the space inside the filter tank, and ensures uniform and efficient deoxygenation reaction.

[0009] The present invention is further configured such that a packing tube is connected to the top of one side of the filter tank, and a cap is threadedly connected to the top of the packing tube. The combination design of the packing tube and the cap allows the resin to be added or replaced without disassembling the main body of the device, simplifying the maintenance process, reducing downtime, and meeting the power plant's requirements for continuous operation of the equipment.

[0010] The present invention is further configured such that the inlet of the water pump is connected to the bottom of the surface of the filter tank through a pipe, and the outlet of the water pump extends to the top of the inner cavity of the storage cylinder through a pipe. The water pump is directly connected to the bottom of the filter tank through a pipe, ensuring that the extracted water sample is the actual water quality after treatment, and the test results are accurate and reliable.

[0012] The present invention is further configured such that a controller is fixedly connected to the top of the placement box. The controller is electrically connected to electrical equipment through wires. As the core control unit, the controller is connected to devices such as electric push rods, drive motors, and electromagnetic flow valves through wires to realize the automated linkage between the deoxygenation process and the detection process. The controller can preset thresholds to trigger responses, thereby improving the intelligence level of the system.

[0013] The present invention is further configured such that there are three electric push rods arranged at equal intervals in a circle. The three electric push rods arranged at equal intervals in a circle synchronously drive the cover plate to rise and fall, avoiding tilting or poor sealing caused by force on one side, ensuring that the cover plate fits tightly with the top of the filter tank, and improving the sealing performance and operational stability of the device.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model integrates a deoxygenation component and a detection component, achieving automated control of the deoxygenation process and real-time monitoring of water quality. In the deoxygenation component, an electric push rod drives the cover plate to open and close, and in conjunction with the drive motor, it drives the stirring rod to fully mix the resin and chemicals in the filter tank. The electromagnetic flow valve precisely controls the amount of chemicals added, and the screw conveyor automatically discharges the expired resin, ensuring efficient deoxygenation. The water pump in the detection component draws water samples after filtration in real time, and the oxygen content detector is driven down to the storage cylinder by an electric push rod to detect the oxygen content. Once dissolved oxygen is found to be excessive, it can trigger timely resin replacement or chemical replenishment, avoiding equipment corrosion problems caused by resin failure, significantly improving the safety and reliability of the power plant water treatment system, reducing manual inspection costs, and realizing unmanned monitoring.

[0028] Example 2

[0030] Specifically: The controller 36 integrates an alarm that can sound an alarm when a test fails. The inlet pipe 28 and outlet pipe 29 clearly define the connection method between the device and the external water system, forming a complete water circulation path. This facilitates integration with the power plant's existing water treatment system, ensuring smooth output of deoxygenated water and improving the device's practicality and compatibility. The support legs provide stable support for the filter tank 1, adapting to different installation environments. The inclined design of the guide plate 4 guides the water flow to the outlet, reducing bottom water accumulation and resin buildup, improving the utilization rate of space inside the filter tank 1, and ensuring uniform and efficient deoxygenation reaction. The combination design of the packing tube and cap allows for resin replenishment or replacement without disassembling the main body of the device, simplifying the maintenance process, reducing downtime, and meeting the power plant's requirements for continuous equipment operation. The water pump 31 is directly connected to the bottom of the filter tank 1 via a pipeline. To ensure that the extracted water sample is the actual treated water quality, the test results are accurate and reliable. The outlet extends above the storage cylinder 35 to avoid water splashing and ensure a stable testing environment. The design of the placement port and the box door facilitates the operation of operators to put in and take out the storage cylinder 35, clean the inside, or calibrate the oxygen content detector 34.

The controller 36, as the core control unit, connects to the electric push rod, drive motor 23, electromagnetic flow valve 26, and other equipment through wires to realize the automated linkage between the deoxygenation process and the testing process. The system can preset thresholds to trigger responses, improving the intelligence level of the system. The three circumferentially spaced electric push rods 21 synchronously drive the cover plate 22 to rise and fall, avoiding tilting or poor sealing caused by unilateral force, ensuring that the cover plate 22 fits tightly with the top of the filter tank 1, and improving the sealing performance and operational stability of the device.

[0031] The working principle of this utility model is as follows: After water enters the inner cavity of the filter tank 1 through the inlet pipe 28, the electromagnetic flow valve 26 is opened by the controller 36 to quantitatively add chemical agents into the inner cavity of the filter tank 1. At the same time, the drive motor 23 is started, which drives the stirring rod 24 to rotate, so that the water, chemical agents and resin in the inner cavity of the filter tank 1 are fully mixed and stirred, improving the filtration and deoxygenation effect. After the deoxygenation work is completed, the filtered and deoxygenated water is pumped into the inner cavity of the storage cylinder 35 by the cooperation of the water pump 31 and the pipeline. Then, the electric push rod 33 is started, which drives the oxygen content detector 34 to move downward and insert the detection head into the storage cylinder 35. The inner cavity can test the treated water. When the test is qualified, the treated water is discharged through the outlet pipe 29 for use. If the test is unqualified, it means that the resin needs to be replaced. At this time, the valve of the inner cavity of the screw conveyor 27 is opened, and the screw conveyor 27 is turned on to discharge the water and resin in the inner cavity of the filter tank 1. When the resin in the inner cavity of the filter tank 1 is completely discharged, the cap is opened and new resin is added through the packing tube. The extension of the electric push rod 21 drives the cover plate 22 to move and separate from the top of the filter tank 1. At this time, the inner cavity of the filter tank 1 can be cleaned. The storage cylinder 35 is taken out by opening the box door, and the water in the inner cavity of the storage cylinder 35 is manually discharged or kept as a stock sample.
