[0042] Both sides of the fixing ring 7 are fixedly connected with transverse plates 14 for lifting the filter screen 6 and taking the filter screen 6 out of the housing 10.

[0043] Working principle: put the porous carbon into the filter screen 6, connect the hoses of the liquid pump 1 21 and the liquid pump 2 22 to the equipment for conveying clean water and the equipment for conveying acid respectively, convey clean water and acid into the shell 2 15 through the connecting pipe 1 19 and the connecting pipe 2 20, turn on the motor 1 to drive the partition 3 to rotate, the clean water and acid mixture is sprayed upward from the spray hole of the stirring plate 4, the liquid level in the shell 10 gradually rises, and the stirring plate 4 stirs the mixed liquid in the shell 10 when rotating to make the clean water and acid mix more evenly, the mixed liquid penetrates into the filter screen 6 and reacts with the porous carbon, so that the alkaline substances in the porous carbon are precipitated for neutralization, and stirring the mixed liquid can improve the efficiency of the mixed liquid entering and exiting the filter screen 6, so that the porous carbon reacts more fully, and while the partition 3 rotates, The filter screen 6 is also driven to rotate by the clamping rod 5 and the mounting rod 13, and the filter screen 6 drives the fixing ring 7, the vertical rod 8 and the round rod 9 to rotate.

When the partition 3 rotates, the filter screen 6 can be vibrated multiple times, and with its own rotation and the stirring of the mixed liquid, the porous carbon inside can be fully dispersed and contacted with the mixed liquid to react, which solves the problem that in the traditional filter washing tank, the porous carbon suspended in the filter screen is easy to sink to the bottom during the water washing process, resulting in insufficient contact with the water washing liquid, resulting in poor water washing effect;

When the reaction is complete, the liquid pump 22 is turned off to stop delivering the acid. The pH detector 32 is connected to the signal sending module 36 for transmitting signals. And send a signal to the staff to operate. When it is necessary to take out the porous carbon that has reacted completely in the filter screen 6, hold the handle 34 to pull up the inner tube 31, slide the iron block 33 into the horizontal groove of the outer tube 30 and magnetically fit with the magnet sheet 35. At this time, the pH detector 32 is located above the outer shell 10, and then rotate the top plate 29 to stagger the outer tube 30 and the filter screen 6. Finally, hold the horizontal plate 14 to take the filter screen 6 out of the outer shell 10, and the remaining mixed liquid in the outer shell 10 can be extracted by an external liquid extraction device.
