Where did the origin of screw press sludge dewatering machine come from?

 

The screw press sludge dewatering machine is a well-known machine in the environmental protection industry in recent years. It is accepted by the majority of customers because of its small footprint, large processing capacity, flexible work and high dewatering efficiency.

So, where is the origin of screw press sludge dewatering machine?

The answer is: Japan

I have to admit that after the Second World War, although Japan's domestic economy was sluggish, with the help of the United States, it quickly entered the era of modern mechanical revolution. The level of mechanical technology and modernization is ahead of other Asian countries.

Development background and improvement:

1. The early development of the filter: the spiral filter first appeared in Germany in the 1960s, and then the former Soviet Union, Sweden, the United States and other countries also manufactured this kind of filter, and it was first used in oil extraction and fish, Filtration in aquaculture industries such as shrimp waste.

2. The development of filters in Germany: The early model of screw press sludge dewatering machine was first used to filter wastes such as fish and shrimp, and subsequent fishermen found that clogging often occurred. German mechanical engineers invented a relatively new type of filter screen structure, moving ring and low stationary ring filter structure. The fixed ring and the movable ring are spaced apart from each other and have a certain filtering gap. The friction between the movable ring and the fixed ring can produce a friction force that promotes the extrusion of the material more than hinders it, thereby improving the filtering and separating effect of the material and avoiding the need for Blockage of high viscosity materials.

3. The filter was officially put into production in Japan: After acquiring this technology, Japan remodeled the shape of the machine and put it into mass production after optimizing the drawings, and officially named it screw press sludge dewatering machine.

4. Development status of screw press sludge dewatering machine: This technology has been introduced to many other countries in the future, and thousands of companies around the world are producing this kind of solid-liquid separation equipment.
