Fully automatic water purification device

Abstract

A fully automatic water purification device comprises a shell, the center of the top end of the shell is provided with a backwashing main pipe, the top end of the shell is provided with an overflow groove, a position close to the top end of the shell is provided with a lightweight packing layer, the center of the shell is provided with a reaction cylinder assembly, the reaction cylinder assembly comprises a tapered cylinder with an inner layer gradually reducing from top to bottom, and a reaction cylinder sleeved on the tapered cylinder and with a sealed top end, the bottom end of the reaction cylinder is provided with a support and is fixedly arranged at the bottom end of the shell, the bottom end of the shell is arranged to be a mud bucket, two sides of the mud bucket are respectively provided with a mud collection box, the mud collection box is connected with the mud bucket, the tail end of the tapered cylinder is connected with a hollow throat, the hollow throat is connected with a tapered return cylinder, the bottom end of the mud bucket is provided with a horizontal water inlet pipe, the tail end of the water inlet pipe is arranged to be a vertically upward bent tube, the tail end of the bent tube is provided with a nozzle, the nozzle rightly faces the tapered return cylinder and stretches into the tapered return cylinder, a position of the horizontal water inlet pipe close to the port of the horizontal water inlet pipe is provided with an aided flushing pipe, and the aided flushing pipe is provided with a ball valve. The device still can guarantee a high flocculation effect on the premise of a fast water inlet speed.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water purification device. Background technique [0002] Sewage treatment usually needs to go through flocculation, filtration, sedimentation and other processes, and finally discharge the water that meets the standard. Among them, in the two processes of flocculation and filtration, flocculants are usually added to the flocculation tank to make the suspended particles in the water or liquid aggregate larger, or form flocs, thereby accelerating the coagulation of particles and achieving the purpose of solid-liquid separation. However, when the water inlet pipe injects water into the flocculation tank, due to the fast water inlet speed, the reaction time between the sewage and the flocculant is short, and the flocculation effect is poor; if the water inlet speed is reduced, the entire sewage treatment efficiency is low.
