Duwan GSJ-2800 Double-Surface Blender with Variable Frequency Speed Control Motor

Impeller diameter: 2800mm

Gearbox reducer

Shaft - 304 Stainless Steel

Propeller fiberglass

Dual-curved blenderWidely used in industries such as environmental protection, chemicals, energy, and light industry, where two-phase or three-phase solid-liquid-gas mixing is required for liquids, especially suitable for coagulation tanks, equalization tanks, anaerobic tanks, nitrification tanks, and denitrification tanks in wastewater treatment processes.

Duwan Environmental GSJThe Type Series Curved Agitator is composed of a drive unit, a double curved impeller body, and installation accessories. To meet the diverse operational conditions of users, the installation is available in two types: dry (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 drive shaft. It is suitable for liquids with high solid content, high water temperature, and abrasive properties. Due to the impeller's automatic alignment feature, the operation is relatively smooth, with the reducer noise below 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, suitable for deep water bodies with stable water quality, free of abrasive properties, with water temperature not exceeding 40°C, and a pH value between 6~9. Its features include noiseless operation and no visual obstructions.

Job Characteristics:

The Jiangsu Du'an Environmental Protection SQJB series curved blade mixer is an efficient mixing equipment suitable for blending various low-viscosity liquids, solid-liquid, and gas-liquid mixtures; it is not only applicable to circular and square pools but is also commonly used for unit arrangement in rectangular water pools.

The propeller mixer primarily overcomes the issue of dead spots commonly found in traditional blade (impeller) mixers and the suboptimal aeration and water-gas mixing in the aeration process, leveraging its advantage of even mixing.

Key Features of the Double-Sided Agitator:

⑴ Suitable for use in various applications involving liquid and solid, as well as gas mixtures, it can replace existing mixing equipment. It achieves a three-dimensional helical mixing, resulting in more uniform mixing and improved efficiency.

⑵ Larger specific surface area impeller, with lower power rating, larger recirculating water flow, low energy consumption; saves 30%-50% energy compared to traditional mixing methods.

③ The entire machine is compact in structure, reliable in operation, and easy to install and maintain.

The impeller is made of reinforced fiber or steel, capable of accommodating various operational conditions and boasts a long service life.

Applicable to standard municipal wastewater treatment conditions

Caution for Installation and Use of Biconical Blender:

1. Prior to installation, a qualified electrician must inspect the motor and electrical equipment, and confirm the direction. The smaller working distance of the impeller from the bottom of the pool should be ≤300mm, and the pool bottom should be flat, sturdy, with no construction debris inside.

2. In case of prolonged equipment downtime, prevent sediment buildup that could lead to impeller blockage and motor damage upon restart.

3. Consider the impeller's inlet and outlet dimensions in a closed pond.

4. Regardless of the installation method, ensure the underwater cable is securely fastened to prevent wear.

5. Please read the product's installation and usage manual carefully before use.
