Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and in particular to a wastewater recycling device. Background Technology

[0002] Ion exchange resins achieve highly efficient ion removal by exchanging functional groups (such as sulfonic acid groups and quaternary ammonium groups) with target ions (such as heavy metal ions, calcium and magnesium ions, and nitrates) in wastewater. Saturated resins can be regenerated using acidic or alkaline solutions (such as hydrochloric acid and sodium hydroxide) to restore their exchange capacity and reduce operating costs.

[0003] When using ion exchange resin to treat wastewater, a resin column is usually set up. The wastewater flows through the resin column and comes into contact with the ion exchange resin, thereby achieving ion exchange. However, if the flow rate is too fast, the contact time may be insufficient, reducing the exchange efficiency.

[0004] Therefore, it is necessary to provide a new wastewater recycling device to solve the above-mentioned technical problems. Utility Model Content

The curved tube design significantly increases the flow path and time of wastewater in the ion exchange resin, allowing for more thorough contact between the wastewater and the resin, thus improving the sufficiency and efficiency of ion exchange. Compared to traditional straight pipes, it can more effectively remove target ions from wastewater. By incorporating a reduction mechanism, the saturated ion exchange resin is regenerated using acid and alkali solutions, restoring its exchange capacity, reducing the need for frequent resin replacements, lowering operating costs, and ensuring the ion exchange resin can continuously and stably remove target ions from the wastewater, thus guaranteeing effective wastewater treatment.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-3 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the wastewater recycling device provided by this utility model; Figure 2 A front sectional view of a preferred embodiment of the wastewater recycling device provided by this utility model; Figure 3 for Figure 2 The diagram shows an enlarged view of part A.

[0024] The wastewater recycling device includes: a treatment tank 1; a partition 2, which is fixedly installed inside the treatment tank 1 and divides the treatment tank 1 into a filtration chamber 3 and a cleaning chamber 4, with the cleaning chamber 4 located above the filtration chamber 3; a curved tube 5, which is fixedly installed inside the cleaning chamber 4 and contains ion exchange resin, with the inlet end of the curved tube 5 extending into the cleaning chamber 4; a water pump 6, which is fixedly installed inside the filtration chamber 3, with a pumping pipe 7 fixedly installed at the inlet end of the water pump 6 and a drain pipe 8 fixedly installed at the outlet end of the water pump 6 and fixedly connected to the curved tube 5; and a reduction mechanism, which is located on the curved tube 5 and used to reduce the saturated ion exchange resin. The treatment tank 1 is the main container of the entire device. The structural design of the partition 2 facilitates the staged treatment of wastewater, with preliminary treatment first performed in the filtration chamber 3 and then advanced treatment such as ion exchange performed in the cleaning chamber 4. The inlet end of the curved tube 5 extends into the cleaning chamber 4, providing a channel for wastewater to enter the curved tube 5 and contact the ion exchange resin. The curved tube design increases the flow path and time of the wastewater within it, which is beneficial for improving the sufficiency of ion exchange. The water pump 6 draws wastewater from the filter chamber 3 and transports it to the curved tube 5, enabling the wastewater to contact and exchange with the ion exchange resin. The reduction mechanism is used to reduce the saturated ion exchange resin. The reduction mechanism can reduce the saturated ion exchange resin, restoring its ability to exchange ions, thereby ensuring that the ion exchange resin can continuously and stably remove target ions from the wastewater, ensuring the wastewater treatment effect. By regenerating the saturated ion exchange resin through the reduction mechanism, the need for frequent ion exchange resin replacement is reduced, the consumption of ion exchange resin is lowered, and thus the operating cost of the wastewater treatment device is reduced.

[0025] The reduction mechanism includes a three-way pipe 9, an addition pipe 10, and a discharge pipe 11. The three-way pipe 9 is fixedly installed on the side of the curved pipe 5 extending outside the treatment tank 1. The addition pipe 10 is fixedly installed on the three-way pipe 9. The discharge pipe 11 is fixedly installed on the treatment tank 1 and on the side where the curved pipe 5 connects to the drain pipe 8. The three-way pipe 9 allows operators to reduce the ion exchange resin in the curved pipe 5 without opening the treatment tank 1, improving operational convenience and efficiency. The structure of the three-way pipe 9 allows it to connect the addition pipe 10 and the curved pipe 5 simultaneously, providing a stable channel for adding the reducing agent and allowing flexible control of the addition process, ensuring that the reducing agent accurately and effectively enters the curved pipe 5 and contacts the saturated ion exchange resin. The addition pipe 10 allows control of the amount and rate of addition of the reducing agent, enabling it to fully react with the saturated ion exchange resin, improving the reduction effect, ensuring the ion exchange resin fully recovers its exchange capacity, and thus guaranteeing the quality of wastewater treatment. The impurity discharge pipe 11 is installed on the side where the curved pipe 5 connects to the drain pipe 8. It can promptly discharge impurities generated during the reduction process, preventing impurities from accumulating inside the curved pipe 5 and affecting the reduction effect of the ion exchange resin and subsequent wastewater treatment. Timely discharge of impurities can prevent them from clogging or damaging other components of the device, ensuring the stable operation of the wastewater recycling device and extending its service life.

[0026] Valves are fixedly installed on the curved tube 5, the addition tube 10, and the discharge tube 11 to control the liquid flow direction. The valve on the curved tube 5 prevents liquid outflow when adding reducing agent, ensuring the reducing agent flows smoothly along the tube to reduce the saturated ion exchange resin, restoring its ion exchange capacity and ensuring effective wastewater treatment. The valve on the addition tube 10 precisely controls the amount and rate of reducing agent addition. Depending on the saturation level of the ion exchange resin and the wastewater quality, the valve is opened or closed as needed to adjust the reducing agent flow rate, ensuring sufficient reaction with the saturated ion exchange resin, improving reduction efficiency, and preventing overuse of the reducing agent, thus reducing costs. During the addition of reducing agent, the valve acts as an isolation device to prevent accidental leakage and ensure operator safety. When no additional reducing agent is needed, closing the valve prevents external impurities from entering the addition tube 10, protecting the cleanliness and stability of the reduction system. The valve on the discharge tube 11 allows for flexible control of impurity discharge based on the generation of impurities during the ion exchange resin reduction process.

[0027] A filter screen 12 is fixedly installed inside the filter chamber 3. The filter screen 12 is columnar. An inlet pipe 13 is fixedly installed on the treatment tank 1, extending between the filter screens 12. The columnar filter screen 12 increases the contact area with wastewater, allowing more opportunities for the wastewater to contact the filter screen 12 as it flows through, thus more effectively intercepting suspended solids, particulate matter, and other impurities in the wastewater and improving filtration efficiency. Compared to other shapes, the columnar structure of the filter screen 12 has better structural stability, can withstand the impact force generated by the flow of wastewater, and is not easily deformed or damaged, ensuring the continuity and stability of the filtration process. The inlet pipe 13 directly introduces the wastewater into the filtration area of ​​the filter screen 12, avoiding disorderly flow of wastewater within the filter chamber 3, ensuring that the wastewater can be fully filtered by the filter screen 12, improving the filtration effect, making the wastewater entering the cleaning chamber 4 for ion exchange treatment cleaner, and reducing the pollution and clogging of the ion exchange resin by impurities.

[0028] A cleaning pipe 14 is fixedly installed on the partition 2, extending between the filter screens 12. A rotating seat 15 is rotatably mounted at the drain end of the cleaning pipe 14, and a nozzle assembly 16 is fixedly installed on the rotating seat 15. The cleaning pipe 14 delivers cleaning liquid to the filter screens 12, and the cleaning liquid sprayed from the nozzle assembly 16 directly impacts the surface of the filter screens 12, effectively removing impurities and dirt adhering to them and maintaining their filtration performance. Because the rotating seat 15 can rotate, it drives the nozzle assembly 16 to rotate as well, allowing it to spray cleaning liquid onto the filter screens 12 from different angles, achieving all-around cleaning and ensuring that all parts of the filter screens 12 are effectively cleaned, thus improving the cleaning effect. The rotating nozzle assembly 16 expands the coverage area of ​​the cleaning liquid, reduces cleaning dead spots, and cleans a larger area of ​​the filter screens 12 in the same amount of time, thereby improving cleaning efficiency, shortening cleaning time, and ensuring that the wastewater treatment device can quickly return to normal operation.

[0029] A fixed gear 17 is fixedly mounted on the rotating base 15, and a rotary motor 18 is fixedly mounted on the partition 2. A drive gear 19 is fixedly mounted on the output shaft of the rotary motor 18, and the drive gear 19 meshes with the fixed gear 17. The rotary motor 18 can control the rotational speed and direction of its output shaft. Through the meshing transmission of the drive gear 19 and the fixed gear 17, this control is transmitted to the rotating base 15, thereby controlling the rotation angle and speed of the nozzle assembly 16. This allows the nozzle assembly 16 to spray cleaning liquid onto the filter screen 12 at the most suitable angle and speed, ensuring that the cleaning liquid can evenly and comprehensively cover all parts of the filter screen 12, effectively removing impurities and improving the cleaning effect. According to the type, quantity, and distribution of impurities on the filter screen 12, the operating parameters of the rotary motor 18 can be flexibly adjusted, thereby changing the rotation angle and speed of the nozzle assembly 16 to meet the needs of different cleaning scenarios and improve the adaptability and flexibility of the device.

[0030] A sealing door 20 is slidably installed at the bottom of the processing box 1, and the sealing door 20 is connected to the filter chamber 3. A support frame 21 is fixedly installed on the processing box 1, and a hydraulic cylinder 22 is fixedly installed on the support frame 21. The output shaft of the hydraulic cylinder 22 is fixedly connected to the sealing door 20. A fixing frame 23 is fixedly installed on the processing box 1, and a guide rod 24 is fixedly installed between the fixing frame 23 and the bottom outer wall of the processing box 1. The guide rod 24 slides through the sealing door 20. The sealing door 20 makes cleaning impurities in the filter chamber 3 convenient and efficient. When the impurities intercepted by the filter screen 12 accumulate to a certain extent, the sealing door 20 is slidably opened by the hydraulic cylinder 22, and the impurities can be discharged from the bottom of the filter chamber 3. This avoids the tedious operation of manually entering the processing box 1 to clean impurities, reducing labor intensity and safety risks. The hydraulic cylinder 22 has the characteristics of large output force, smooth movement, and high control precision. By precisely controlling the extension and retraction of the output shaft of the hydraulic cylinder 22, the opening degree and closing state of the sealing door 20 can be accurately controlled, ensuring a good seal between the sealing door 20 and the bottom of the treatment tank 1 and preventing wastewater leakage. The guide rod 24 provides precise guidance for the sliding of the sealing door 20, ensuring that the sealing door 20 maintains a straight line movement during sliding without deviation or wobbling. This ensures the sealing fit accuracy between the sealing door 20 and the bottom of the treatment tank 1, avoiding sealing problems caused by the deviation of the sealing door 20, and improving the reliability and stability of the device.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the wastewater recycling device provided by this utility model is as follows:

[0033] In operation, wastewater enters the filter chamber 3 of the treatment tank 1 through the inlet pipe 13. Since the inlet pipe 13 extends between the columnar filter screens 12, the wastewater can directly and fully contact the filter screens 12, effectively intercepting suspended solids, particulate matter, and other impurities in the wastewater, achieving preliminary filtration. The filtered wastewater accumulates in the filter chamber 3. At this time, the water pump 6 is activated, and the water pump 6 extracts the filtered wastewater through the suction pipe 7, then transports it through the drain pipe 8 to the curved tube 5 in the cleaning chamber 4. The special design of the curved tube 5 increases the flow path and time of the wastewater within it, allowing for more sufficient contact between the wastewater and the ion exchange resin in the curved tube 5. The target ions in the wastewater undergo an exchange reaction with the functional groups on the ion exchange resin, thereby achieving efficient removal of the target ions and completing the deep treatment of the wastewater.

[0034] During wastewater treatment with ion exchange resin, the resin gradually reaches saturation and loses its exchange capacity as the ion exchange reaction proceeds. At this point, the saturated ion exchange resin needs to be reduced to restore its exchange capacity. Acid or alkaline solutions (such as hydrochloric acid or sodium hydroxide) are added to the three-way pipe 9 through the addition pipe 10. The valve connecting the three-way pipe 9 and the curved pipe 5 is opened, while the valve leading from the curved pipe 5 to the subsequent treatment process is closed. This allows the reducing agent to flow along the curved pipe 5, fully contacting and reacting with the saturated ion exchange resin, displacing the target ions adsorbed on the resin and restoring its ion exchange capacity. During the reduction process, impurities are generated with the liquid flow. The valve on the impurity discharge pipe 11 is opened to promptly discharge impurities out of the treatment tank 1, preventing their accumulation in the curved pipe 5, which would affect the reduction effect of the ion exchange resin and the subsequent wastewater treatment process.

[0035] During wastewater treatment, the filter screen 12 continuously intercepts impurities. When these impurities accumulate to a certain level, they affect the filtration effect. At this point, the cleaning system is activated to clean the filter screen 12. Cleaning liquid is delivered to the filter screen 12 through the cleaning pipe 14. Simultaneously, the rotary motor 18 is activated, driving the drive gear 19 to rotate. Since the drive gear 19 meshes with the fixed gear 17 fixedly mounted on the rotating base 15, it drives the rotating base 15 to rotate, thereby causing the nozzle assembly 16 fixedly mounted on the rotating base 15 to rotate as well. The nozzle assembly 16 sprays cleaning liquid onto the filter screen 12 from different angles, achieving all-round cleaning of the filter screen 12, ensuring that all parts of the filter screen 12 are effectively cleaned, improving the cleaning effect, reducing cleaning dead spots, and guaranteeing the filtration performance of the filter screen 12.

[0036] When a large amount of impurities accumulate in the filter chamber 3, cleaning is required. The hydraulic cylinder 22 is activated, and its output shaft extends, causing the sealing door 20 to slide open at the bottom of the treatment chamber 1. Because the guide rod 24 provides precise guidance for the sliding of the sealing door 20, it maintains a straight line during the sliding process, preventing deviation or wobbling and ensuring a precise seal between the sealing door 20 and the bottom of the treatment chamber 1. Impurities can then be discharged from the bottom of the filter chamber 3, avoiding the tedious manual operation of entering the treatment chamber 1 to clean impurities, reducing labor intensity and safety risks. After cleaning, the output shaft of the hydraulic cylinder 22 retracts, causing the sealing door 20 to close, ensuring a good seal between the sealing door 20 and the bottom of the treatment chamber 1, preventing wastewater leakage.
