The internal structure of 180 types of solid-liquid separator

Understanding the internal structure of the solid-liquid separator is helpful to the installation of the equipment.

The solid-liquid separator works continuously by spiral extrusion, which is suitable for separating materials with phase-containing particles ≥ 0.5-1.0mm, a large proportion of solid in the feed liquid, and low moisture content after separation.

It is especially suitable for the treatment of wood-based panel factory wastewater, raw manure water of cattle, pigs, chickens, and other livestock in farms, and slaughterhouse sewage.

The built-in structure is that the working part of the screw extruder is a screw, the section of the screw blade is perpendicular to the axis, and the material is pushed in the direction of the deformation nozzle with a component force parallel to the axis.

Auger with 1 / 4 pitch length shall be provided between the feed inlet and the rear wall of the cylinder to prevent coal from channeling into the bearing.

The clearance between the screw and the cylinder is generally no more than 2 ~ 3mm to avoid the backflow of coal and improve the extrusion efficiency.

The manure separator used for hot press molding extrudes materials at 400 ~ 500 ℃, and the spiral blade and bushing are easy to wear. It should be made of heat-resistant and wear-resistant materials. Tungsten carbide can also be overlaid on the outer edge of the spiral blade to improve its wear resistance.

The deformation nozzle is used to restrict the annular section of plastic coal material to a long straight section.

The size of the connecting section of the movable nozzle and the deformation nozzle is the same as that of the long square mouth of the deformation nozzle. The upper part is a movable pressing plate and the lower part is a groove of rectangular sections. The preform pressure can be adjusted by adjusting the force applied to the movable pressing plate.

The raw manure water of livestock and poultry treated by the solid-liquid separator can produce biogas after anaerobic treatment. It can be used as fuel, power generation, or leaf fertilizer after pressure filtration. It can also be pumped to Dapeng as plant nutrients.

Using solid-liquid separators to treat farm wastewater can turn waste into treasure, which is conducive to protecting the environment and producing great benefits.
