Product Overview
Ceramic filter is mainly used for fine coal slurry recovery,
equipped with an engine base, under the engine base setting a fine
coal slurry liquid trough, in this liquid trough, equipped with
liquid level controller, both ends with negative pressure water
tank, one side of this water tank is equipped with negative
pressure connected assembly fix, another side is vacuum pump
pipeline connecting with a vacuum pump; on the engine base, there
is a coal slurry recovery rotor, this rotor consists of main axle,
multilevel ceramic filter disc, stripper plate, multisection
effluent connecting pipeline piping support plate, negative
pressure connecting assembly plate.
The rotor is located in liquid trough; the ceramic filter disc
consists of many ceramic cavity micropore plates, those plates
located in a same axes connect by the effluent connecting pipeline.
Working Principle
Ceramic filter shape and mechanism is similar with the working
principle of vacuum belt filter, under the effect of pressure
difference, suspended matter particle are intercepted on the medium
surface then form as filter cake while liquid outflow from filter
medium to realize solid-liquid separation. The difference is filter
medium, ceramic filter plate is with micropore that can produce
wicking effect. That makes the wicking effect stronger than vacuum
force, and micropore keep a state full of liquid. In any case,
ceramic filter plate don't allow air go through, because of this
reason, while solid-liquid separating, energy is saving
and vacuum degree is high. Ceramic filter mainly consists of rotor,
stirrer, scraper components, slurry trough, distributor, ceramic
filter plate, vacuum system, cleaning system, automaticcontrol
system etc.
Main Structure
Ceramic filter is mainly consisting of roller system, mixing
system, ore slurry feed and discharge system, vacuum system,
filtrate discharging system, scraping system, back washing system,
united washing system (ultrasonic cleaning, automatic matching acid
cleaning), full-automatic control system, trough body, rack etc.
Trough body uses corrosion resistant stainless steel, can load ore
pulp. Stirring system is stirring mixing materials in trough body
to avoid the rapid subsidence of materials. Ceramic filter plate is
installed on roller, roller can be rotated by the drive of stepless
speed change reduction gears.
Filter medium of ceramic filter is ceramic filter plate, doesn’t
need filter cloth, that reduces cost of production. The 1mm gap
between scraper and filter plate prolongs the service life while
discharging.
Using back washing and united cleaning etc. methods, full-automatic
control by PLC, equipped with inverter, liquid level meter etc.
device. While starting up, ore pulp valve is monitored by level
meter, it controls height of ore pulp level. When to high level,
PLC control system rapidly opens filtrate pump outlet valve to
drain water quickly. Ceramic can use long-range control or
centralized control according to different requirement by
customers.
