The utility model relates to the technical field of chemical
wastewater treatment, in particular to a waste liquid collecting
pool of an all-
vanadium liquid flow
energy storage power station. The device comprises a
liquid storage pool, a movable scraping plate, a sealing plate, a filter screen, a vertical movable
pipe and a waste box, an upper through hole is formed in one end of the
liquid storage tank; a bottom groove is formed in the bottom end of the inner side of the
liquid storage tank; the movable scraping plate is slidably mounted on the inner side of the liquid
storage pool, and a first driving
assembly used for driving the movable scraping plate to move is mounted on the liquid
storage pool; the waste box is arranged on the inner side of the bottom groove. The sealing plate is arranged at the upper end of the liquid
storage pool, and a fixing rod is connected between the sealing plate and the waste box; a second driving
assembly used for driving the sealing plate to ascend and descend is installed on the liquid storage
pool. A floating plate is fixedly mounted at the bottom end of the vertical movable
pipe, and a hose is communicated with the upper end of the vertical movable
pipe; the filter screen is arranged at the bottom end inside the
liquid storage tank. According to the technical scheme,
solid substances and liquid precipitated in the
liquid storage tank can be conveniently separated, so that subsequent treatment work is facilitated.
