And the drain pipe is provided with a first valve for controlling the time and the entering amount of the precipitating agent entering the precipitation chamber.

The upper end of the settling chamber is provided with a water inlet pipe, the lower end of the settling chamber is provided with a water outlet pipe, sewage is guided into the settling chamber through the water inlet pipe, and liquid and sediment after sedimentation are discharged out of the settling chamber through the water outlet pipe.

And the water outlet pipe is provided with a second valve for controlling the discharge time and discharge amount of liquid and sediments in the settling chamber.

The stirring kettle is provided with a motor, one side of the motor is provided with a rotating rod, the rotating rod is arranged in the stirring kettle, and the rotating rod is provided with a plurality of first stirring paddles and a plurality of second stirring paddles and is used for uniformly mixing a precipitator in the stirring kettle.

Be equipped with the through-hole on the first stirring rake, reduce the stirring resistance, and enable more abundant that the precipitant mixes.

The improved stirring device is characterized in that a first scraper blade is arranged on the first stirring paddle, the first scraper blade is matched with the inner wall of the stirring kettle, a second scraper blade is arranged on the second stirring paddle, the second scraper blade is matched with the inner wall of the stirring kettle, and the first scraper blade and the second scraper blade can scrape residues on the inner wall of the stirring kettle to be utilized.

The utility model has the advantages as follows:

firstly, through stirred tank with precipitant (generally adopt modified potassium hydroxide and active carbon granule or calcium carbonate) misce bene, then let in the precipitant room through drain pipe and catheter and deposit sewage in, the catheter sets up to be the arc and one end stretches into in the precipitant room, sets up a plurality of holes on the catheter for in scattering the precipitant is even the precipitant, make more even that sewage deposits.

Detailed Description

The present invention will be further described with reference to the following detailed description.

As shown in fig. 1-3, a precipitator adding device comprises a stirring kettle 1 and a precipitation chamber 2, wherein a drain pipe 12 is arranged at the bottom of the stirring kettle 1, a liquid guide pipe 24 is arranged on the precipitation chamber 2, the liquid guide pipe 24 is communicated with the drain pipe 12, the liquid guide pipe 24 is arc-shaped, one end of the liquid guide pipe extends into the precipitation chamber 2, and a plurality of holes 25 are arranged on the liquid guide pipe 24 and used for uniformly scattering the precipitator into the sewage in the precipitation chamber 2 for uniform precipitation.

The drain pipe 12 is provided with a first valve 11 (electric valve) for controlling the time and amount of the precipitant entering the precipitation chamber 2. The upper end of the settling chamber 2 is provided with a water inlet pipe 21, the lower end is provided with a water outlet pipe 23, sewage is guided into the settling chamber 2 through the water inlet pipe 21, and liquid and sediment after sedimentation are discharged out of the settling chamber 2 through the water outlet pipe 23.
