[0015] The embodiment of the utility model provides a device for preparing aluminum sulfate solution.

[0016] See also Figure 1-Figure 3 , an automatic material recovery device in titanium dioxide production wastewater, including a shell 12, characterized in that the shell 12 is a cylindrical structure made of stainless steel welding, a filter bag 5 of a cylindrical structure is fixed in the middle of the shell 12, a liquid inlet 15 is arranged on the right side of the upper part of the shell 12, the liquid inlet 15 penetrates the shell 12 and is arranged at the upper position of the filter bag 5, a liquid outlet 6 is arranged on the left side of the lower part of the shell 12, a collecting hopper 7 is arranged at the lower part of the shell 12, the upper part of the collecting hopper 7 is fixed to the bottom end of the filter bag 5, the collecting hopper 7 is a contracted cone structure, and a conveyor 8 is arranged at the bottom end of the collecting hopper 7, a rotating motor 1 is arranged at the middle position of the top of the shell 12, a rotating shaft 2 is arranged at the center position of the bottom end of the rotating motor 1, and a cross-scraper 13 is arranged at the bottom end of the rotating shaft 2, a brush 14 or a rubber layer is arranged on the outer side of the scraper 13, a plurality of circular through holes 16 are opened on the scraper 13, a plurality of backwashing pipes 3 are arranged on the inner side of the middle part of the shell 12, and a backwashing pipe 3 is arranged on the inner side of the middle part of the shell 12. A number of nozzles 4 are arranged on the washing pipe 3, a conveying motor 11 is arranged at the right end of the conveyor 8, a conveying shaft 9 is arranged at the center position on the left side of the conveying motor 11, and a propeller blade 10 is arranged on the outside of the conveying shaft 9. During the operation of the entire device, a suspension containing granular materials is conveyed to the liquid inlet 15 by a conveying pump, and the suspension is pumped into the filter bag 5. Water will flow out along the micropores of the filter bag 5, and the granular materials will be deposited inside the filter bag 5. Under the continuous rotation of the scraper 13, the granular materials fall into the collecting hopper 7 for collection, and further removed from the equipment. Compared with the static sedimentation tank, this has high material collection efficiency, does not require a large amount of space, and has high efficiency. Of course, in order to prevent the filter bag 5 from being blocked, we adopt two methods. The first is to set a brush 14 or a rubber layer on the outer edge of the scraper 13, and the second is to arrange a backwash pipe 3 along the outside of the filter bag 5. Both methods can solve the problem of bag blockage.
