I. Purpose
The LDH-type Plow Blade Mixer (hereinafter referred to as the mixer) is a new, high-efficiency powder mixing equipment innovatively developed by our company. This machine is widely used in solid-solid (i.e., powder-to-powder) mixing, solid-liquid (i.e., adding liquid to powder) mixing, as well as composite processes such as wet granulation, drying, and concentration in industries including chemicals, pharmaceuticals, pesticides, plastics, rubber, fertilizers, building materials, concrete admixtures, food, monosodium glutamate, salt, feed additives, dyes, metallurgy, and mining. It is a versatile, multi-functional mixing equipment with strong adaptability and a wide range of applications.
II. Types and Their Meanings
III. Structural Characteristics:
The structure of the mixer is shown in the figure. It mainly consists of a transmission part, a horizontal cylinder, a plow blade group shaft, a flying blade group, a discharge valve, a liquid spraying device, and other components.
The transmission part of the mixer is composed of components such as the motor, cycloidal pinwheel reducer, coupling, and plow blade shaft.
The horizontal cylindrical body is used for holding materials, with several openings on the body for material loading/unloading and observation. The犁刀 shaft support base is fixed on the cover plates at both ends of the cylinder.
The plow blade assembly consists of the plow blade, plow blade arm, and main shaft. The plow blade is mounted on the main shaft via the plow blade arm and is designed with a split structure for easy disassembly and assembly.
The flying knife assembly consists of multiple flying knives, directly driven by an auxiliary motor and installed on the side of the cylinder.
The discharge valve is installed at the bottom of the cylinder (except for continuous discharge) and is used to close and release materials.
The liquid spraying device of the mixer is fixed above the cylinder, and the nozzle uses an agricultural spray head, providing good spraying effect.
IV. Working Principle
After the mixer is started, the plow blade is driven to rotate by the plow blade shaft, causing the material to undergo radial circumferential turbulence along the cylinder. At the same time, the material is thrown out along the normal direction of both sides of the plow blade. When the material that has been thrown out and is undergoing circumferential turbulence passes through the flying knife group, it is quickly and forcefully scattered by the high-speed rotating flying knives. Under the combined action of the plow blade and the flying knives, the material continuously overlaps and diffuses, achieving uniform mixing in a short period of time with high mixing precision.
For materials requiring solid-liquid mixing, the liquid mixture is evenly sprayed onto the moving materials inside the drum through a liquid spraying device.
