Description
Technical field
The invention belongs to solid-liquid separation technique field, more particularly to a kind of belt filter press.
Background technology
Separation of solid and liquid is that there is very common technology process, a separation equipment being commonly used in chemical engineering unit operation
Plate and frame type filter-press, vacuum belt filter, belt filter press etc..
Plate and frame filter press and vacuum belt filter and belt filter press three are in contrast, the advantages of plate and frame filter press is fortune
Low energy consumption for row, separative efficiency height, filter residue moisture content etc., the disadvantage is that labor intensity is big, automation degree of equipment is low.Although at present oneself
Through there is the plate and frame filter press of automatic pulling plate, but filter cloth cleaning, filter cloth dismounting must be by being accomplished manually, so labor intensity is still
It is larger.The advantages of vacuum belt filter and belt filter press is energy continuous operation, automation degree of equipment is high, labor intensity is low, is lacked
Point is that operation energy consumption is high, separative efficiency is poor, filter residue moisture content is high.
Vacuum belt filter is with belt filter press in contrast, vacuum belt filter only has a filter cloth, the pressure of filter cloth both sides
Difference comes from the pressure difference between atmospheric pressure and vacuum.Belt filter press is made of two filter clothes up and down, and slurry is distributed in two layers
Between filter cloth, extruding force between two layers of filter cloth and pressure roller removes the moisture in slurry.The common advantage of the two is exactly, if
Standby high degree of automation, labor intensity are low；The two common disadvantage is that, separative efficiency is poor, and filter residue moisture content is high.
Although plate and frame filter press is there is this big disadvantage of labor intensity, the separative efficiency of plate and frame filter press is high, gained
The moisture content of filter residue is low, and just because of this advantage, in many occasions, plate and frame filter press is still widely deployed, cannot
It is substituted.
The separative efficiency of plate and frame filter press is high, the moisture content of gained filter residue is low, main cause, first, filter pressure is high, filter
The pressure difference of cloth both sides is big, second is that filter cloth is static in filter process, is conducive to the formation of filter cake, if plate and frame filter press filters
Filter cake is dried up with compressed air again afterwards, can further reduce filter cake moisture content.The obtained filter cake of plate and frame filter press
Moisture content is different according to material and slightly difference, generally within the scope of 50%-60%.
The pressure difference of vacuum belt filter filter cloth both sides comes from the pressure difference between atmospheric pressure and vacuum, this pressure difference often exists
0.4 to 0.6 atmospheric pressure, the i.e. pressure differences of filter cloth both sides only have 0.04 to 0.06MPa.The pressure difference of filter cloth for plate-frame type filter presses both sides comes
From in the pressure head of feed pump, usually, the lift of plate and frame filter press feed pump is 50 meters, then the pressure difference of filter cloth both sides can reach
To 0.5MPa, it is equivalent to ten times of vacuum belt filter or so.
The filter process of belt filter press is dynamic, and pressure difference is relatively low, so the cake moisture that solid phase is formed is higher, is had
Even cannot form filter cake.Belt filter press is used for de-watering of slurries, front and back there are two area, when gravity dewatering zone, second is that squeezing
Pressure-off pool.In gravity dewatering zone, the pressure difference of filter cloth both sides only has the gravity of material itself；In extrusion dehydration area, upper and lower two
Layer filter cloth sloughs moisture, the moisture content of belt filter press gained filter residue is 80% or so under the extruding of pressure roller.
Plate and frame filter press is still another shortcoming is that the filtering complete period is long, and it is too low to account for complete period ratio filter cycle,
The ratio that the slag dumping period accounts for the complete period is excessively high.By taking existing plate and frame filter press as an example, about 4 hours complete periods are filtered, from being fed to
Filter cake compacting, compressed air drying occupy 0.5 hour, and slag dumping filter wash cloth needs 3.5 hours.If a plate and frame filter press has 40
Block filter plate, then needing 40 pieces of filter plate block-by-blocks dismantling slag dumping, block-by-block filter wash cloth paving filter cloth in slag dumping, when occupying a large amount of
Between.The structural shape of existing plate and frame filter press determines such case, and can not improve.
With technological progress, the continuous improvement of industrial automatization, the big equipment of those operation labor intensity is by city
Eliminating for field, is a kind of inexorable trend.Just be separated by solid-liquid separation for this field, need a kind of novel device, can holding plate
The high efficiency of frame filter press, and high the degree of automation with belt filter press, low operation labor intensity, it might even be possible to realize nothing
People operates, and the development of this equipment will be as a kind of urgent demand.
Invention content
Technical problem to be solved by the invention is to provide the low belt filter press of a kind of energy continuous operation, labor intensity.
In order to solve the above technical problems, the present invention provides a kind of belt filter press；
Including at least upper filter cloth, lower filter cloth and main filter assemblies；
Main filter assemblies include the first top board moving up and down and the first lower supporting plate of fixed position, are pressed on first
Plate lower face is provided with indent on first, and the first lower supporting plate upper surface corresponds to indent position on first and is provided with the first lower groove, the
Once bottom portion of groove is provided with the first filtrate channel through the first lower supporting plate, and main filtering group is discharged through the first filtrate channel in filtrate
Outside part, the first top board first on the first lower groove of indent and the first lower supporting plate composition for filtrate passes through first convey
Channel；
Upper filter cloth and lower filter cloth are tensioned by several rollers and are driven, and upper filter cloth and lower filter cloth all pass through the of main filter assemblies
One transfer passage.
After such structure, in filter process, the filtering of the filter condition and plate and frame filter press of this belt filter press
Condition is identical, so separative efficiency also will be identical as plate and frame filter press, filter cake moisture content certainty and the plate and frame filter press phase of gained
Together；And this belt filter press may be implemented continuous automatic discharge, clean filter cloth automatically, need one by one when plate and frame filter press deslagging
Filter plate, gradually deslagging are pulled, deslagging is slow, and deslagging period holding time is long, and the present invention compared with plate and frame filter press, wash by deslagging
The time that filter cloth occupies is seldom, and the most of the time belongs to filter cycle, and automation degree of equipment greatly improves；This belt
