GSJ-2000-4.0 Double Curve Agitator for High Chloride Wastewater Treatment

2. Working principle and structure
The upper surface of the impeller body of the hyperbolic FRP impeller mixer is a hyperbolic structure formed by the rotation of hyperbolic busbars around the axis of the impeller body. The impeller structure design maximizes the combination of fluid characteristics and mechanical motion. The equation of a hyperbola is a curved surface formed by the rotation of the xy=b curve along the y-axis; In order to cater to the flow of water, the water is designed to enter from the center of the impeller, which reduces the turbulence of the inlet and ensures uniform pressure of the liquid on the surface of the impeller, thereby ensuring the balance of the whole machine in motion. There are eight guide vanes evenly distributed on the gradually opening double curved surface. The potential energy obtained by supplementing the inflow with the self weight pressure of the liquid and the centrifugal force generated by the rotation of the impeller form kinetic energy. The liquid moves tangentially along the circumferential direction of the impeller through the hyperbolic structure transition under the action of gravity acceleration. Under the reflection of the pool wall, it forms a top-down circulating water flow, thus obtaining cross flow in the axial (y) and radial (x) directions (as shown in Figures 1 and 2). It is precisely because of the structural characteristics of the hyperbolic mixer impeller and its proximity to the bottom of the pool that its working position determines its direct anti settling effect on suspended solids, which can achieve ideal mixing effect during operation and effectively eliminate mixing dead corners. A large specific surface area can result in extensive water exchange.
The impeller structure consists of fluid guide, stirring components, and transmission parts (as shown in Figure 3)

3. Engineering applicationsGSJ-2000-4.0 Double Curve Agitator for High Chloride Wastewater Treatment
The hyperbolic FRP impeller mixer is composed of a power part, a hyperbolic impeller body, and installation accessories. In order to meet the needs of users under different working conditions, the installation design is divided into two types: dry (also known as vertical shaft) and submersible (as shown in Figures 4 and 5). Dry installation utilizes bridge positioning through transmission, powered by a dry motor and gearbox. It is used in liquids with high solid content, high water temperature, and abrasive properties. Due to the automatic correction function of the impeller, the operation is relatively stable, and the gearbox noise is less than 60 decibels. Submersible installation, eliminating the need for cable trays, using submersible power, utilizing equipment self weight positioning, flexible and convenient installation, suitable for deep water, stable water quality, non abrasive water bodies, water temperature not exceeding 40 ℃, pH value between 6-9, characterized by no noise and no visual barriers.

4. Job characteristics
The hyperbolic FRP impeller mixer, as an efficient mixing equipment, is suitable for mixing and stirring various low viscosity liquids, solid-liquid, and gas-liquid mixtures; Not only suitable for circular and square pools, but also commonly used in rectangular pools for unit arrangement.
