[0002] With the development of economy and the continuous improvement of science and technology, my country's sewage treatment industry has developed very rapidly. Flocculants are needed in sewage treatment. Flocculants mainly bring positive (negative) charged groups and some negative (positive) charged particles or particles in water that are difficult to separate close to each other, reduce their potential, make them unstable, and use their polymerization properties to concentrate these particles and separate them by physical or chemical methods. Flocculants will be stored in the hopper when in use, which is convenient for continuous addition of flocculants;

[0003] When the existing flocculant dry powder storage device is in use, when judging the remaining amount of flocculant inside the flocculant storage device, the storage device needs to be opened for manual judgment, which is inconvenient to judge whether there is a shortage of material in time, and it is inconvenient to detect the internal flocculant powder in real time. Moreover, when feeding, the flocculant powder is easy to adhere to the top of the discharge port, which is easy to cause the discharge port to be blocked for a long time, thereby reducing the practicality of the hopper when in use. Therefore, the utility model proposes a visual dry powder hopper for a flocculant dosing system to solve the above problems. Utility Model Content

When in use, the weight of the silo 7 itself is weighed by the weight sensor 2, and then an appropriate value is set in the controller. When the weight detected by the weight sensor 2 is lower than the set value, the staff is reminded that material needs to be added, and the remaining amount of flocculant powder in the silo 7 is monitored in real time.

[0018] The vibration mechanism includes a telescopic rod 11, a movable rod 12, an impact head 13, a telescopic spring 14, a side plate 15, a first servo motor 16 and an eccentric wheel 17.

The output end of the first servo motor 16 is connected to one end of the eccentric wheel 17, and one end of the eccentric wheel 17 cooperates with one side of the impact head 13. When in use, the first servo motor 16 is started to drive the eccentric wheel 17 to rotate. Due to the eccentric design of the eccentric wheel 17, the movable rod 12 is driven to move through the impact head 13. Therefore, with the cooperation of the telescopic rod 11 and the telescopic spring 14, the silo 7 is driven to vibrate, so that the flocculant powder is not easy to adhere to the inner wall of the discharge port 10 when discharging, and the discharge port 10 is not easy to be blocked, thereby greatly improving the practicality of the hopper when in use.

[0019] A limiting shaft 4 is provided through the interior of the mounting plate 3, and the bottom end of the limiting shaft 4 is connected to the top end of the bottom plate 1. There are multiple limiting shafts 4, and the multiple limiting shafts 4 are distributed in a ring shape on the mounting plate 3. When in use, the cooperation of the multiple limiting shafts 4 makes the hopper more stable during use.

[0020] The rotating mechanism includes a second servo motor 18, a rotating shaft 19, a stirring shaft 20, a connecting rod 21 and a scraper 22. The second servo motor 18 is installed at the top of the silo 7, and the rotating shaft 19 is installed inside the silo 7. The output end of the second servo motor 18 is connected to one end of the rotating shaft 19. The outer wall of the rotating shaft 19 is installed with a stirring shaft 20, and connecting rods 21 are installed above and below the outer wall of the rotating shaft 19.

The powder attached to the inner wall of the silo 7 can also be scraped off and continued to be stirred, so as to save the flocculant powder and make the flocculant powder more effective when used.

[0021] Working principle: First, use the weight sensor 2 to weigh the weight of the silo 7 itself, and then set an appropriate value in the controller. When the weight detected by the weight sensor 2 is lower than the set value, it reminds the staff to load the material, and then pour the material from the feed port 9 into the interior of the silo 7 for storage. At this time, start the second servo motor 18 to rotate the bottom shaft 19, so as to drive the stirring shaft 20 to rotate, and use the stirring shaft 20 to stir the flocculant powder to prevent it from agglomerating. The powder attached to the inner wall of the silo 7 can also be scraped off and continued to stir. When unloading, start the first servo motor 16 to drive the eccentric wheel 17 to rotate. Due to the eccentric design of the eccentric wheel 17, the movable rod 12 is driven to move through the impact head 13. Therefore, with the cooperation of the telescopic rod 11 and the telescopic spring 14, the silo 7 is driven to vibrate, so that the flocculant powder is not easy to adhere to the inner wall of the unloading port 10 when unloading. The design of the transparent window 8 allows the staff to clearly see the remaining flocculant powder inside the silo 7 and add material to it.
