[0002] Dilute acid refers to an acidic solution with a low concentration. In the acid production process, dilute acid purification is an important step. With increasing environmental pressure, the requirements for dilute acid purification are becoming more and more stringent. Dilute acid filtration devices are equipment for purifying dilute acid and are key to whether dilute acid treatment meets the standards.

[0003] A patent with authorization announcement number "CN220677064U" discloses an adsorption filtration device for dilute acid purification, including a tank. Three support legs are fixedly installed on the bottom of the tank, and a liquid outlet pipe is also fixedly installed on the bottom of the tank. Two fixing blocks are fixedly installed on the outside of the tank. A connecting ring is movably installed inside the tank, and two handles B are fixedly installed on the outside of the connecting ring. Two fixing rods are fixedly installed on the bottom of the connecting ring. Through the addition of a stirring rod and activated carbon, a motor drives the shaft to rotate, which in turn agitates the dilute acid inside, accelerating the filtration rate. The activated carbon then performs a second adsorption filtration of the dilute acid, increasing the filtration and impurity removal effect of the device and enhancing its practicality.

[0024] A motor A3 is installed in the middle of one side of the mixing chamber 2. A rotating rod 5 is installed at the output end of the motor A3. A mixing rod 6 is installed on one side of the rotating rod 5. A screw conveyor rod 11 adapted to the sleeve 10 is fitted on one side of the sleeve 10. A transmission component 4 connected to the rotating rod 5 is installed on one side of the screw conveyor rod 11. A collection box 13 connected to the sleeve 10 is installed at the top of one side of the filter chamber 1. A door is installed on one side of the collection box 13 to facilitate the collection and cleaning of impurities. An adjustment component is installed in the middle of one side of the adjustment box 16. A feed pipe is installed at the top of one side of the filter chamber 1. A discharge pipe is installed at the bottom of one side of the purification box 14. The feed pipe and the discharge pipe are used for feeding and discharging dilute acid.

[0025] Furthermore, the adjustment assembly includes a motor B17, a stirring rod 18, a docking groove 19, a docking block 20, a sealing plug A21, a rotating rod 22, an electric push rod 23, a push plate 24, a movable rod 25, and a sealing plug B26. An electric push rod 23 is located in the middle of one side of the adjustment box 16, and a push plate 24 is located at the output end of the electric push rod 23. A movable rod 25 connected to the push plate 24 is fitted onto the top of the adjustment box 16 on the side away from the connecting pipe 27. A set of connecting rods is provided on one side of the movable rod 25. A sealing plug B26 is adapted to the connector 27. A motor B17 is installed at the bottom of one side of the push plate 24. A rotating rod 22 is installed at the output end of the motor B17. A sealing plug A21 that cooperates with a set of connecting pipes 27 at the bottom is installed on the outer side of the rotating rod 22. A docking block 20 is installed on one side of the rotating rod 22. A stirring rod 18 is sleeved on one side of the packing tank 15. A docking groove 19 that cooperates with the docking block 20 is installed on one side of the stirring rod 18 to facilitate backwashing of the packing in the packing tank 15.

[0026] Furthermore, the transmission assembly 4 includes two sets of pulleys and belts. Pulleys are provided on one side of the spiral conveyor rod 11 and on the outer side of the rotating rod 5, and belts are fitted on the outer sides of both sets of pulleys. When the rotating rod 5 rotates, it can drive one set of pulleys to rotate. Then, one set of pulleys can drive the other set of pulleys through the belt transmission, so that the spiral conveyor rod 11 rotates synchronously with the rotating rod 5.

[0027] Furthermore, the top of the regulating box 16 is provided with a feed trough, the bottom of the regulating box 16 is provided with a drain trough, and one end of the drain trough is provided with a drain pipe, which can divide the regulating box 16 into two spaces, so as to facilitate communication with the purification box 14 during dilute acid filtration and backwashing.

[0028] Working principle: When filtering dilute acid, the device can inject dilute acid through the feed pipe. After the dilute acid enters the mixing chamber 2, the motor A3 can be started. The motor A3 can drive the rotating rod 5 to rotate, and then the rotating rod 5 can drive the mixing rod 6 to stir and mix the dilute acid and flocculant in the mixing chamber 2, so that the impurities in the dilute acid are separated. After stirring, the pump body 8 can be started, and the dilute acid can be drawn into the sleeve 10 by the guide pipe 7. At this time, the rotating rod 5 can drive the screw conveyor 11 to rotate under the transmission component 4. The dilute acid can be filtered through the filter screen 12 and discharged into the guide box 9. The filtered impurities can be continuously conveyed to one side by the rotation of the screw conveyor 11, so that the impurities enter the collection box 13 for collection.

[0029] After the dilute acid is filtered, it can be guided into the regulating box 16 through the flow guide box 9, and then into the purification box 14 through the flow guide pipe 27. When the dilute acid passes through the packing tank 15, it can be adsorbed and filtered by the polymer adsorption packing, which can completely remove the impurities in the dilute acid. The filtered dilute acid can be discharged from the discharge pipe.

[0030] When the packing material in the packing trough 15 needs to be cleaned after the device has been used for a period of time, the electric push rod 23 can be started to drive the push plate 24 to move to one side. At this time, the push plate 24 can push the movable rod 25 so that the sealing plug B26 can block the top set of connecting pipes 27, while the rotating rod 22 can drive the sealing plug A21 to release the blockage of the bottom set of connecting pipes 27. At the same time, the rotating rod 22 can drive the docking block 20 to engage with the docking groove 19. At this time, water can be introduced through the discharge pipe to backwash the packing material. The backwash wastewater can enter the bottom of the regulating tank 16 and be discharged through the sewage pipe. During backwashing, the motor B17 is started to run. The motor B17 can drive the rotating rod 22 to rotate, and then drive the stirring rod 18 to rotate through the connection between the docking groove 19 and the docking block 20. This can stir the packing material in the packing trough 15, so that the filter cake accumulated in the packing layer can be better separated from the packing material, thus enhancing the washing effect.
