Turnover type oblique plate precipitation tank

Abstract

The invention provides a turnover type oblique plate precipitation tank, which aims at solving the problems of sludge settling and inconvenience in sludge discharging in the existing oblique plate precipitation tank. The turnover type oblique plate precipitation tank comprises a casing 1, a water inlet passage 2, a precipitation area 3, an oblique plate 4, a clean water area 5, a water outlet groove 6, a sludge hopper 7, a sludge discharge pipe 8, a left fixed hole 9, a right fixed hole 10, and a fixing long nail 11, wherein holes are formed in the left and right outermost sides of the oblique plate 4; when the oblique plate 4 is inclined to the left and fixed, the fixing long nail 11 penetrates through the hole in the oblique plate 4 at the leftmost side, and is inserted into the left fixed hole 9, and then the oblique plate 4 is fixed; when the oblique plate 4 is inclined to the right and fixed, the fixing long nail 11 penetrates through the hole of the oblique plate 4 at the rightmost side, and is inserted into the right fixed hole 10, and then the oblique plate 4 is fixed. The turnover type oblique plate precipitation tank has the advantages that the oblique plate can be adjusted into a vertical angle, so as to favorably discharge the sludge; after sludge is discharged, the oblique plate can be turned over and used; after turning over, the upper surface with sludge settling previously is changed into the lower surface, the settled sludge is flushed away by water flow and falls down.

Description

technical field [0001] The invention belongs to the field of water treatment, and more specifically belongs to a reversible inclined plate sedimentation tank. Background technique [0002] The inclined plate sedimentation tank is a high-efficiency sedimentation tank composed of multiple inclined plates. The inclined plate sedimentation tank uses the principle of "shallow sedimentation" to shorten the sedimentation distance of particles, thereby shortening the sedimentation time; and increasing the sedimentation area of ​​the sedimentation tank, thereby improving the treatment efficiency. Usually the sloping plate sedimentation tank of the same type has a burial capacity 7 to 10 times higher than that of an ordinary advection sedimentation tank. [0003] After the inclined plate sedimentation tank has been in operation for a period of time, sludge will be deposited on the inclined plate, which will affect the sedimentation effect and treatment capacity of the sedimentation t...
