Description

Technical Field

[0001] This utility model relates to the field of alkaline solution purification technology, specifically an alkaline solution purification device for filtering impurities. Background Technology

[0002] In industrial production, alkaline solutions are often used as reaction media, cleaning agents, or neutralizing agents. However, long-term recycling or introduction of raw materials can lead to the accumulation of impurities (such as suspended particles, organic matter, metal ions, etc.), affecting process stability and product quality.

[0003] Chinese patent CN210711030U discloses an "Industrial Waste Alkali Treatment Device for MVR Evaporation Crystallization System," which includes a chamber with a filter cartridge fixedly installed inside. The filter cartridge is connected to a cleaning pipe, a sewage pipe, and a drain pipe. Precipitates and particulate impurities in the mixed solution are blocked by the filter cartridge. When cleaning the filter cartridge, cleaning water is needed to flush the precipitates and impurities inside the filter cartridge through the sewage pipe. This structure not only consumes water resources but also makes it inconvenient to clean and recycle the precipitates.

[0004] Chinese patent discloses a waste alkali liquid recovery device (authorization announcement number CN213265863U). In this patented technology, the cover is hinged to the box body, and the filter bag can be detachably installed at the feed inlet, which can facilitate cleaning of the filter bag and recovery of sediment.

[0005] However, it has certain drawbacks: when the reaction is completed and the pipeline valve is opened to discharge the mixture, the alkali solution and the precipitate generated by the reaction are easy to adhere to the inner wall and bottom edge area of ​​the reaction tank, and are difficult to be completely discharged during the discharge process. The residual alkali solution and precipitate not only increase the difficulty of subsequent cleaning, but may also cause scaling or corrosion on the inner wall of the equipment, affecting the stability of long-term operation.

[0023] The tank cover 2 is provided with a feed pipe for the alkaline solution and precipitant to be purified to be discharged into the purification tank body 1;

[0024] The precipitant can be a sulfide, which reacts with heavy metal ions (such as nickel, copper, lead, etc.) in the waste alkaline solution to form insoluble sulfide precipitates, or it can be a hydroxide, which adjusts the pH value to cause metal ions to form hydroxide precipitates. The choice depends mainly on the requirements.

[0025] Both valve 1 (3) and valve 2 (8) are preferably electric valves;

[0026] Motor 5 is used to drive the stirring rod 6 to rotate, so as to mix and stir the alkaline solution and precipitant to ensure that the reaction is complete;

[0027] Valve 28 is opened to discharge alkali and precipitate;

[0028] Filter plate 12 is used for filtration, allowing alkaline solution to pass through and filtering out the precipitate;

[0029] After unscrewing the support bolt 14, the annular plate 10 can be pulled to the left to disassemble the entire support frame 11 and its internal filter plate 12 for easy cleaning.

[0030] Valve 3 is used to discharge the alkaline solution after it is opened.

[0031] exist Figure 1 , Figure 2 and Figure 4 In the middle: The upper surface of the tank cover 2 is provided with a scraping mechanism 16 located inside the C-shaped seat 4. The scraping mechanism 16 includes a fixed tube 17, which movably passes through the upper surface of the tank cover 2. The stirring rod 6 movably passes through the fixed tube 17. A seat bearing 18 is installed on the outside of the fixed tube 17 and is fixedly connected to the upper surface of the tank cover 2. A fixing bolt 19 is movably connected above the seat bearing 18 on the front surface of the fixed tube 17. The rear end of the fixing bolt 19 is threadedly connected to the inside of the stirring rod 6. A scraping component 20 is provided at the lower end of the left side surface of the fixed tube 17. The scraping component 20 includes a fixed rod 21. The right end of the fixed rod 21 is threadedly connected to the lower end of the left side surface of the fixed tube 17. A scraper 22 is fixedly connected to the left end of the fixed rod 21. The scraper 22 movably fits against the inner surface of the purification tank body 1 and the conical hopper 7.

[0032] The pedestal bearing 18 includes a bearing housing and a bearing fixed inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixed in the bearing housing, and the fixing tube 17 is fixed in the inner bearing ring. Therefore, the pedestal bearing 18 and the fixing tube 17 are in a state of mutual rotation.

[0033] The surface of the stirring rod 6 is provided with a threaded hole that matches the fixing bolt 19;

[0034] After stirring is complete, turn off the motor 5, rotate the fixed tube 17 so that the hole on it is aligned with the threaded hole on the surface of the stirring rod 6, pass the fixing bolt 19 through the hole on the fixed tube 17 and screw it into the threaded hole to fix the fixed tube 17 and the stirring rod 6 together. Then turn on the motor 5 to drive the stirring rod 6 to rotate, and the fixed tube 17 will also rotate, thereby driving the scraper 20 to clean the inner wall of the purification tank 1 and the conical hopper 7, scraping off the adhering alkali and sediment.

[0035] The scraper 22 includes a plate body and an elastic pad fixed to the plate body. The plate body is fixed to the fixing rod 21, and the elastic pad is attached to the inner wall of the purification tank 1 and the conical hopper 7.

[0036] The working principle of this utility model is as follows: The alkaline solution to be purified and the precipitant are added into the purification tank body 1 through the feed pipe of the tank cover 2. The motor 5 is started to drive the stirring rod 6 to rotate, so that the alkaline solution and the precipitant are fully mixed and reacted to generate precipitate. After the reaction is completed, the motor 5 is turned off, and the fixing bolt 19 is screwed into the threaded hole of the stirring rod 6 to fix the fixing pipe 17. The motor 5 is then started again to drive the stirring rod 6 and the fixing pipe 17 to rotate synchronously, so that the elastic pad of the scraper 22 scrapes off the alkaline solution and precipitate adhering to the inner wall of the purification tank body 1 and the conical hopper 7. Then, the valve 2 is opened to discharge the mixture to the filter plate 12 below the conical hopper 7 for filtration. The alkaline solution is discharged through the valve 3 after passing through the filter plate 12, and the precipitate is trapped on the filter plate 12. During cleaning, the valve 2 is closed, the support bolt 14 is unscrewed and the annular plate 10 is pulled to the left to pull out the support frame 11 and the filter plate 12 as a whole, thus completing the cleaning and recycling of the precipitate.
