Description

Automatic stirring device for central barrel of chemical oil remover for sewage treatment

Technical Field

The utility model relates to a sewage treatment chemistry degreaser center bucket automatic stirring device belongs to sewage treatment device technical field.

Background

The system contains a large amount of oil and suspended matters because the cooling water in the metallurgical industry, the chemical industry and the like is circularly used, and the chemical oil remover separates the substances such as oil and the like from the water in a mode of adding a chemical agent to enable the oil and the suspended matters in the water to generate flocculation and coagulation reactions, thereby being an important treatment process of the sewage treatment process of the industrial circulating cooling water.

The central barrel is used as a medicament feeding area and a flocculation chemical reaction area of the chemical oil remover, and the whole sewage treatment effect is directly related to whether the liquid medicament and the sewage are uniformly mixed and whether the flocculation reaction is sufficient or not. At present, the central barrel of the domestic chemical degreaser adopts a blade stirrer stirring mode, the blade stirrer is easy to stir unevenly in the operation process due to the problems of the abrasion of a speed reducer and other faults, the scaling of blades and the like, liquid medicine and sewage cannot be well mixed and reacted, and the most direct result is that the quality of discharged water is unqualified. And maintenance of the agitator requires a large amount of maintenance cost and workload of workers.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a central bucket automatic stirring device of sewage treatment chemical degreaser can make liquid medicine and sewage at central bucket internal homogeneous mixing, abundant reaction, guarantees the sewage treatment effect, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

the utility model provides a central bucket automatic stirring device of sewage treatment chemistry degreaser, contains central bucket, outlet pipe, inlet tube and mouth of pipe elbow, and central bucket is the cask, connects an inlet tube and four outlet pipes on the central bucket, four outlet pipes evenly arrange along the circumferencial direction of central bucket, and the inlet tube is located the below of four outlet pipes, and the delivery port department at the inlet tube is connected to the mouth of pipe elbow, and the mouth of pipe elbow is located central bucket, and the play water direction of mouth of pipe elbow is parallel with the circumference tangential direction of central bucket, and the play water of mouth of pipe elbow can form the swirl that uses the central axis of central bucket as the centre of a circle in central bucket.

The vortex formed by the water outlet of the pipe orifice elbow in the central barrel is a clockwise vortex.

The pipe orifice elbow is in threaded connection with the water outlet of the water inlet pipe.

The pipe orifice elbow is DN600 elbow.

The water inlet pipe is close to the bottom of the central barrel.

Adopt the utility model discloses, utilize whirl pond pump package pressure, make water automatic formation swirl in central bucket through mouth of pipe elbow to make sewage and liquid medicine homogeneous mixing, and the alumen ustum that just is difficult for destroying flocculation reaction and forms replaces the effect of blade agitator betterly.

The utility model has the advantages that: the liquid medicine and the sewage can be uniformly mixed and fully reacted in the central barrel, the sewage treatment effect is ensured, and the spare part consumption cost, the maintenance cost, the electricity consumption cost, the labor cost and the like of the blade stirrer are reduced. In addition, the pump set of the cyclone pool has moderate lifting pressure and better water flow rotating speed, and greatly reduces the sludge accumulation in the central barrel.
