¡¡¡¡In our country, wet method is often
adopted when choosing coal by floatation. To reduce water
content of clean cola is one of the important problems
in coal industry that need to be solved.
¡¡¡¡With the development and progress of
our society,enhancement of the sense of environmental
protection,international and domestic coal industries
begin to develop new filter dehydration equipment which
can improve product quality, save water and increase utilization
factor of raw coal. According to the development trend
of coal washing industry,we have sucessively established
cooperative relationship with Qinghua University, Tianjin
University, Zhejiang University etc.. We also invited
Fu Junwei, an expert on separation industry, to research
"Jingjin brand" series clean coal filter press with technicians
in our company. This new kind of filter press has following
characteristics: high filter speed, low water content
in filter cake, convenient operation, high automaticity,
sustainable stability etc..
¡¡¡¡Characteristics of "Jingjin brand"new,
high efficiency clean coal filter press:
¡¡1, Filter plate is made up of polyethylene
material. Low weight, good airproof, excellent compression
resistance. Its compression resistance is 38.6-49.2MPa,super
molecule polyethylene plate is below 35MPa£» aging resistance
is far better than that of polyethylene. Filter speed
is about 30% higher than that of common filter plate.
¡¡¡¡2, Enhancing polypropylene filter plate
was researched by our company, produced by most advanced
machine, double screw extruder. High pressure resistance(pressure
can reach 2.5MPa), high temperature resistance(≥150C),
anticorrosion,,aging resistance(It can be used for 30
years), short filter cycle, good washing effect. High
pressure PP diaphragm filter press was first produced
in our company. Drum pressure can reach 1.6MPa.
¡¡3, XZ200/1500 filter press was produced
by our company. Filter concentration:160-250g/L. When
the granularity is ≤0.5mm,capacity for dealing
with filter cake can reach 13-16m3/h,water content of
filter cake can be reduced to 18%.
¡¡4, "Jingjin brand"new type waste coal
filter press has improved the structure of filter plate
and filter cloth. Super thin new material is adopted for
filter cloth. High filter speed, low water content of
filter cake(can be reduced to 25%).
¡¡¡¡The above are the conclusions drawn
in the practices of "Jingjin brand" high efficiency
clean coal filter press and waste coal filter press.
