Duwan Environmental ProtectionGSJ-1500The dual-curved mixer can create large-volume flow mixing devices, achieving wide-area circulation and soft water flow with less power.Dual Curved BlenderOur impeller structure design maximizes fluid characteristics and mechanical motion.The double-curved blade impeller features a surface formed by the rotation of the xy=b curve along the y-axis. Designed to accommodate water flow, the water enters from the center of the impeller, which reduces the turbulence of the incoming water and ensures uniform pressure on the impeller surface, thereby maintaining the overall balance of the machine during operation. Eight guide vanes are evenly distributed on the involute double arcs, utilizing the potential energy obtained from the supplementary water entry due to the liquid's own weight pressure, which combines with the centrifugal force generated by the impeller's rotation to form kinetic energy. Under the influence of gravity acceleration, the liquid moves tangentially along the circular path of the impeller, forming a circular water flow from bottom to top under the reflection of the赤壁. Therefore, it is possible to obtain cross-water flow in both the axial (y) and radial (x) directions. It is precisely due to the double-curved impeller that...QuicklyEliminating dead mixing spots.

Duwan Environmental ProtectionGSJ-2000The double曲面 mixer is composed of a drive unit, a double曲面 impeller, and installation accessories. To meet the diverse operational conditions of users, the installation is divided into dry-typeAvailable in two types: horizontal (also known as vertical shaft) and submersible. The dry installation involves fixing the drive unit to the work bridge, transferring kinetic energy to the impeller components in the medium through a transmission shaft. It is suitable for liquids with high solid content, high water temperatures, and abrasive properties. Due to the impeller's automatic alignment feature, the operation is relatively smooth, with the reducer noise less than 60 decibels. The submersible installation eliminates the need for bridge structures, utilizing submersible power and the equipment's own weight for positioning. It is flexible and convenient to install, ideal for deep water bodies with stable water quality, free of abrasive properties, with water temperatures not exceeding 40°C, and a pH value between 6 and 9. Its features include noiseless operation and no visual obstructions.

The upper surface of the double-curved impeller body is formed by the rotation of the double-curved generatrix around the axis of the impeller body, creating a double-curved structure. Its unique impeller design maximizes the combination of fluid characteristics with mechanical motion. The equation of the hyperbola isThe xy=b curve rotates along the y-axis to form a solid surface body; to accommodate water flow, the design allows water to enter from the center of the impeller, which reduces the turbulence of the incoming water while ensuring uniform pressure on the impeller surface, thereby maintaining the balance of the entire unit during motion. There are eight guide vanes evenly distributed on the involute double arcs, which utilize the potential energy obtained from the supplementary water intake due to the liquid's own weight pressure, along with the centrifugal force generated by the impeller's rotation, to form kinetic energy. Under the action of gravity acceleration, the liquid moves tangentially along the impeller circumference through the double-surface structure. Due to the reflection from the pool wall, a circular water flow is formed from top to bottom, thus achieving cross水流 in both the axial (y) and radial (x) directions. It is precisely because of the structural characteristics of the vertical paddle mixer's impeller and its installation close to the bottom of the pool that its working position determines its direct anti-settling effect on suspended particles, achieving ideal mixing results during operation and effectively eliminating dead mixing spots. A large specific surface area allows for a large-scale exchange of water bodies.

Dual-surface mixer selection is dependent on the shape of the tank, volume, liquid concentration, medium density, and temperature of the equipment.Parameters such as PH are relevant. The main basis is to determine the effective service area of each unit, and according to the principle that the pool length-to-width ratio does not exceed twice, the rectangular pool can be divided into several equal working units, thereby determining the number of mixers.

Dual-curved mixer features: As a high-PerformanceThe mixing and blending equipment is suitable for blending various low-viscosity liquids, solid-liquid, and gas-liquid mixtures; it is not only applicable to circular and square ponds but is also commonly used for modular arrangements in rectangular ponds.

The wave-type mixer primarily overcomes the issue of dead corners and poor aeration and water vapor mixing effects commonly found in traditional blade mixers, leveraging its advantage of even mixing.

Dual-curved mixer working characteristics:

Smooth flow, three-dimensional circulation, and no dead spots in stirring.

2. Adjusting the flow rib height to accommodate varying water depths.

3. Elastic fixed connections, stable and reliable operation

4. Compact overall structure, reliable operation, easy installation and maintenance, and low investment costs.

The impeller is made of glass fiber reinforced plastic, capable of accommodating various operating conditions and boasting a long service life.

6. Suitable for various applications involving liquid and solid, as well as gas mixtures, it can replace existing mixing equipment to achieve a three-dimensional, helical mixing effect. The stirring is more even, with alternating left and right rotational directions, enhancing mixing efficiency.

7. The dual-curved mixer features a larger specific surface area impeller, with a smaller power configuration, a larger circulating water flow, and low energy consumption, saving up to 30% to 50% of energy compared to traditional mixing methods.
