Working Principle

The Coulter in the Coulter mixer rotates with the main shaft to make the material turbulent along the radial circumference of the barrel arm. At the same time, the radial material flows through the flying knife group along the line and is scattered by the flying knife rotating at high speed. It is constantly changed and compounded, so that the material can be mixed evenly in a short time.

Features

● The horizontal Coulter mixer is composed of transmission part, horizontal cylinder, coulter group shaft, flying knife group, discharge valve, painting device, etc.

● The transmission part includes cycloidal pinwheel reducer with motor and coupling, which mainly changes the movement of the motor into the required speed and torque to the complex cutter shaft;

● The horizontal cylinder is made of rolled steel plate and used for holding materials. Several holes are opened on the cylinder for incoming and outgoing materials and observation. The plow shaft support seat is fixed on the cover plate at the two ends of the cylinder;

● The Coulter group shaft is composed of a coulter, a coulter arm and a main shaft. The coulter is installed on the main shaft with the Coulter arm and serves as a Haff structure, which is convenient for disassembly and assembly;

● The flying knife group is composed of multiple flying knives, which are directly driven by the motor and installed on the side of the cylinder to prevent dust from entering the bearing. The flying knife shaft adopts multi-channel sealing structure;

● The discharge valve is installed at the bottom of the cylinder (except continuous discharge), which is used to close and discharge materials. Its work is realized through the handle and four-bar mechanism;

● The painting device is fixed on the circumference of the cylinder, and the nozzle adopts agricultural nozzle, which has good spraying effect.

● Horizontal plough mixer is widely used in solid-solid (i.e. liquid added to the powder) mixing, wet granulation, drying, concentration and other composite processes in chemical industry, coating, medicine, food, feed, fuel, metallurgy, mining and other industries.

Generally speaking, the plow mixer is cylindrical horizontal, driven by horizontal shaft, and there is local mixed slurry in the cylinder. There are four parts that affect the movement of materials.

● The equipment shape is horizontal and cylindrical.

● The plow is shaped like a plow. It is fixed on the horizontal transmission shaft by the support and rotates along the wall, so that the materials not only make diffusion movement, but also make friction and shear action with each other. At the beginning of material mixing, the plow rotates to continuously update the material surface and increase the activity of particles. It is a typical diffusion mixing. At the same time, the particles rub violently with each other and have the effect of shear mixing. The coulters are distributed radially on the horizontal transmission shaft, and there is a certain included angle between the coulters. When moving, they are not inserted into the powder at the same time, which greatly reduces the resistance in the powder. One of the outstanding characteristics of plow mixer is low mixing energy consumption.

● The flying knife is composed of three simple blades, similar to the blades of an electric fan. There are multiple layers in pagoda shape, which are placed under the side of the mixer wall, and the rotating speed is 1450 ~ 1900r / min. The function of the flying knife is to make the material move violently along the axial direction. The number of throwing knives depends on its scope of action.

● The position, direction and atomization ability of the nozzle affect the dispersion of silicone oil. If silicone oil is sprayed near the Throwing Knife, its initial dispersion is through material convection; Silicone oil is sprayed to the opposite side of the flying knife, and its initial dispersion is through the violent friction, shear and diffusion between material particles. There are obvious differences between the two dispersion effects.

● Short mixing time and good adaptability to the mixing of materials with large differences in particle size and density. The structure features are especially suitable for liquid mixing and wetting particles, and the particle size is between 0.3-3mm.

Scope of Application

It is used in chemical industry, medicine, pesticide, veterinary medicine, food, feed, feed additive, plastic and other industries, such as solid-solid (powder and powder), solid-liquid (a small amount of liquid is added to the powder) mixing, wet granulation, drying and other composite processes; It is especially suitable for the mixing of viscous or colloidal additives.
