High speed disperser is also known as a coating disperser in the coating industry. As the name suggests, it plays the role of high-speed dispersion in all kinds of pigments. It is also the simplest type of grinding and dispersion equipment for coatings. It can be used as pre-mixing equipment for pigments in conjunction with the grinder, or as grinding and dispersion equipment for ultra-fine pigments alone. However, this machine is a multi-functional high-speed disperser, so it can stir, dissolve and mix other materials. It is a machine with very high durability.

Structure composition of high speed disperser

The high-speed disperser is mainly composed of four parts: transmission mechanism, lifting mechanism, mixing container and heating device, and stepless speed regulation device. The specific instructions are as follows:

1. Transmission mechanism of high-speed disperser: it is driven by a motor and transmitted to the shaft through the pulley. The shaft is connected with the mixing rod through the coupling to realize the mixing of the coating liquid. The belt pulley transmission has a simple structure, economical use, and convenient disassembly, which is suitable for this product.

2. Lifting mechanism of high-speed disperser: the platform lifting mechanism adopts hydraulic transmission to realize lifting, which is the main feature that distinguishes various motor lifting platforms. People shake the rocker of the manual pump on the workbench to drive the movement of the piston of the hydraulic cylinder, and then use the four one-way valves to control the oil circuit to hydraulically transfer the oil in the cylinder into another lifting hydraulic cylinder. Finally, the transmission workbench can move up and down freely, and the lifting height range is limited to less than one meter. Such manual pump the biggest advantage is that the differential cylinder block is used, which will drive the hydraulic top to rise whether shaking up or down. When it needs to fall, just open the oil unloading valve, and the working platform will fall automatically.

3. Agitator and heating device of high-speed disperser: the mixing container is a barrel similar to the cylinder body formed by welding steel plates, but the difference is that it has a heating device - an in-line thermocouple. Thermoelectric electrode wire has good uniformity, high stability, good sensitivity, and low price.

4. Stepless speed regulation device of high-speed disperser: step-less speed regulation is relative to step-by-step speed regulation. The speed can be adjusted directly at the maximum and minimum values. It is not limited by gears, and the size of the speed can be adjusted at will. It can realize the control device without level regulation. It can send similar adjustment signals or devices that play the role of adjustment to the equipment it drives.

Working principle of high speed disperser

The serrated circular dispersion disk of the high-speed disperser disperses at high speed in the container to complete the process of solid-liquid dispersion, wetting, depolymerization, and stabilization.

• Make the slurry flow in a rolling annular flow, generate strong vortices, and the particles on the slurry surface drop to the bottom of the vortex in a spiral shape;

• A turbulent zone is formed at the edge of the dispersion disk 2.5-5mm, and the slurry and particles are strongly sheared and impacted;

• The upper and lower beams are formed outside the area, and the slurry is fully circulated and overturned;

• The dispersing plate of the dispersing machine is in a laminar flow state, and the slurry layers with different flow rates diffuse each other to play a dispersing role.
