Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment agent adding and mixing device for wastewater treatment. Background Technique

[0002] In the wastewater treatment industry, additives need to be processed by a mixing device. A mixing device refers to a unit operation that uses mechanical or hydrodynamic methods to disperse two or more materials with each other to reach a certain degree of uniformity.

[0003] However, there are some problems in the prior art: the mixing device for additives in wastewater treatment needs a stirring rod to stir and mix during the mixing process. However, the stirring range of the traditional stirring rod is relatively limited, resulting in low mixing efficiency and easy cost waste. Therefore, we propose a wastewater treatment agent adding and mixing device for wastewater treatment. Content of the Utility Model

[0005] The utility model is realized as follows. A wastewater treatment agent adding and mixing device for wastewater treatment includes a mixing tank. The outer wall of the lower end of the mixing tank is connected with supporting feet. The bottom of the mixing tank is connected with a discharge valve. The upper end of the mixing tank is connected with a detachable upper cover. The upper end of the upper cover is connected with a motor and a feeding funnel. The lower end of the motor is connected with a rotating shaft. The rotating shaft penetrates through the upper cover and extends into the mixing tank. A plurality of mixing shafts are connected to the outer wall of the rotating shaft inside the mixing tank. A detachable first stirring component and a second stirring component are connected between the mixing shafts arranged symmetrically up and down. The second stirring component is located inside the first stirring component.

[0006] Preferably, a stirring claw is threadedly connected to the lower end of the rotating shaft.

[0007] Preferably, the outer wall of the mixing shaft is provided with a first connection hole and a second connection hole.

A plurality of protrusions are arranged on the outer wall of the first outer cylinder. The second stirring component includes an inner cylinder and a second outer cylinder. The second outer cylinder is sleeved outside the inner cylinder. A plurality of stirring shafts are connected to the outer wall of the second outer cylinder.

[0009] Preferably, limiting edge strips are integrally formed on the outer edges of the upper and lower ends of the inner cylinder.

[0010] Preferably, both upper and lower end faces of the inner cylinder are provided with inwardly recessed telescopic grooves. A telescopic shaft is connected inside the telescopic groove. One end of the telescopic shaft extending into the telescopic groove is connected with a limiting block. One side of the limiting block away from the telescopic shaft is connected with a spring, and the other end of the spring is connected with the inner wall of the telescopic groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the motor drives the rotating shaft, the rotating shaft drives the mixing shaft.
