PP melt-blown filter machine application field and working principle solid-liquid separation centrifuge separation performance measurement index Aug 06, 2018

The solid-liquid separation centrifuge has been widely used in starch, chemical, pharmaceutical, industrial wastewater treatment and other industries. It is a new generation of solid-liquid separation equipment that has been carefully improved by the company based on years of field experience. It is more efficient and more based on the original basis. Energy saving and safer.

 

In order to more accurately measure the solid-liquid separation performance of the solid-liquid separation centrifuge, it is necessary to pay attention to the separation factor, which is the ratio of the centrifugal force and the gravity of the separated material in the drum. The larger the separation factor, the faster the separation is usually. The better the separation effect.

 

Under normal circumstances, the separation factor of the industrial solid-liquid separation centrifuge is 100 to 20000, the separation factor of the ultra-speed tubular solid-liquid separation centrifuge is as high as 62000, and the separation of the analytical ultra-speed solid-liquid separation centrifuge is up to 610000. Another factor that determines the processing capacity of the solid-liquid separation equipment is the working area of the drum, and the large processing capacity is also large.

 

In addition, the finer the solid particles in the suspension, the more difficult it is to separate, and the fine particles carried away in the filtrate or the separation liquid are increased.

In this case, the solid-liquid separation centrifuge requires a high separation factor to be effectively separated. When the viscosity of the liquid in the suspension is large, the separation speed is slowed down. The difference in density between the components of the suspension or emulsion is advantageous for centrifugal sedimentation, while centrifugal filtration of the suspension does not require a density difference between the components.

 

PP melt-blown filter core machine mainly adopts fully automatic control system in the process of operation, which can continuously produce filter elements of various specifications. PP melt-blown filter core machine is easy to operate, high in output, high in efficiency and long in service life. The equipment adopts the frequency conversion speed control system, which has low power consumption, low loss, good product quality, stable performance and high filtering precision. The radial multi-layer structure of the filter element is realized to achieve the layered filtering effect of the filter element.

PP meltblown filter machine application field

PP meltblown filter machine is widely used in household water purification and industrial wastewater pretreatment industries to a certain extent, such as pretreatment of purified water, circulating cooling water, drinking water, laboratory water, boiler water, oil field water injection and chemical industry. , pharmaceutical, electroplating, printing, paint, color expansion, fuel, beer, beverage and other industries.

Principle of PP melt blown filter machine

The extruder heats and melts the PP particles to a liquid state. Compressed air from the Roots blower or air compressor and the air tank is sent to the oven for heating. The hot air is sprayed from the nozzle to form a filament through the pressure (the nozzle contains hundreds of small holes). ), the last spun filament reaches the screw of the winding device, the screw continues to rotate and form a filter element, and the filter element automatically advances to the automatic cutting machine. The automatic cutting machine can cut the required length according to the customer's requirements.
