Overview

The JBK frame mixer is mainly used for dissolving and stirring chemicals in water supply plants and sewage treatment plants. Choosing the appropriate stirrer based on the physical properties, capacity, and stirring purpose of different media can play a significant role in promoting chemical reaction rates and improving production efficiency. The frame mixer is generally used for mixing Congee like materials, and the mixing speed should be 60-130 r/min

Product Details

The JBK frame mixer is mainly used for dissolving and stirring chemicals in water supply plants and sewage treatment plants. Anchor and frame mixers belong to the same category, collectively known as anchor frame mixers. The impeller diameter of this type of mixer has a larger ratio to the tank diameter. Choosing the appropriate stirrer based on the physical properties, capacity, and stirring purpose of different media can play a significant role in promoting chemical reaction rates and improving production efficiency. It is generally used for mixing Congee like materials, and the appropriate mixing speed is 60-130 r/min. It and the slurry mixer are two common mixing devices, and their main differences lie in the mixing method and applicable fields.

Paddle type classification:

According to its shape, it can be roughly divided into anchor type, elliptical frame type, cone bottom frame type, box type, and anchor frame type. The applicable high viscosity is 200-300 Pa · s.

Application fields:

Anchor frame agitators typically operate at low speeds and do not generate significant shear forces when stirring low viscosity liquids, making them unsuitable for liquid-liquid and gas-liquid dispersion. On the other hand, this type of impeller moves at a high flow rate inside the tank, with horizontal swirling flow dominating and lacking good mixing uniformity. However, the flow velocity near the tank wall can achieve a higher heat transfer film coefficient than other impellers, making it commonly used for heat transfer and crystallization operations. In addition, due to the large diameter of the blade and its proximity to the bottom of the tank, it is also commonly used to stir high concentration slurries and precipitating slurries. It is also commonly used for stirring high viscosity fluids.

structure

The connection method between the anchor frame mixer and the mixing shaft is similar to that of a paddle type mixer, in which one end of the impeller and the mixing shaft are connected to form a semi-circular collar, and then the two semi-circular rings of the two sides of the blades are clamped on the mixing shaft with bolts, while the blades and the mixing shaft are fixed with through shaft bolts. Due to the large external dimensions of the impeller, for ease of assembly and disassembly, most of the blades are connected by bolts, and only small ones are cast or welded. The impeller is mostly made of flat steel and angle steel. In order to improve the strength of the impeller, reinforced steel plates can also be used. The anchor impeller in the glass lined mixing tank is mostly welded with steel round or flat tubes, and its outer wall is coated with glass.

The difference between a frame mixer and a slurry mixer:

1. A frame mixer is a device that uses rotating blades within a frame to forcibly mix liquid or granular materials through convection. Usually suitable for mixing low viscosity, easily miscible liquid or semi-solid materials, such as emulsifiers, solutions, slurries, etc.

2. A slurry mixer uses one or more blades on a rotating shaft to shear, disperse, and mix high viscosity, easily clumped materials. Suitable for materials with high viscosity and easy agglomeration, such as colloids, pastes, dispersed dyes, pigments, etc.

Therefore, the choice between a frame mixer or a slurry mixer should be determined based on the specific material characteristics and mixing requirements.
