Description
Technical field
The present invention relates to solid-liquid body separation technology field.
Background technology
Solid-liquid body separation equipment is: various types of filter presses.Filter press just is applied to Chemical Manufacture from 18 beginnings of the century, is widely used in chemical industry, coal, pharmacy, metallurgy, dyestuff, food so far, brewages, industry such as pottery and environmental protection.Because various filtering equipment insufficiency of function, filter press present, public use both at home and abroad mainly is divided into two types.One type is to be that main equipment has: plate and frame filter press, vacuum filter with the liquid filtering.Another kind of is to be that master's equipment is: belt filter press, horizontal spiral filter press with the squeezing of filter residue, mud class.
The plate and frame filter press operation principle is: plate and frame filter press constitutes one group of filter chamber by filter plate and the filter frame alternately arranged.There is groove on the surface of filter plate, and its protrusion position is in order to support filter cloth.On the corner of filter frame and filter plate through hole is arranged, the assembling back constitutes complete passage, can feed suspension, washings and draw filtrating.Plate, each jug rest of frame both sides are on crossbeam, by hold down gag pressure strip, frame.Filter cloth between plate, the frame plays gasket seal.By charging pump suspension is pressed into filter chamber, on filter cloth, forms filter residue, until being full of filter chamber.Filtrating pass filter cloth and along filter plate trench flow to sheet frame corner passage, concentrate to discharge.Filtration finishes, and can feed to clean to wash the water washing filter residue.After the washing, also feed compressed air sometimes, remove remaining cleaning solution.Open filter press removal filter residue subsequently, clean filter cloth, pressure strip, frame begin next operation cycle again.Plate and frame filter press has reliable liquid filtering efficient, uses very extensively, and weak point is that operation the time does not have that filter residue is drained, pressing function, can not work continuously.Remove filter residue, clean filter cloth, all need frequent dismounting body.
The operation principle of vacuum filter is: form negative pressure at the filtrate (liquid place as the motive force of filtering.Be divided into upper and lower chamber to container with filter medium.Suspension adds epicoele, and getting into cavity of resorption through filter medium under pressure becomes filtrating, and solid particle is trapped within the filter medium surface and forms filter residue.The filter cake layer that accumulate on the filter medium surface in the filter process is thickeied gradually, and liquid increases through the resistance of filter cake layer thereupon, and the rate of filtration reduces.When filter chamber is full of filter residue or the rate of filtration too hour, stop to filter, remove filter residue, make filter medium regeneration, to accomplish filtration cycle one time.The equipment that vacuum filter has epicoele to open wide can be removed the filter residue that is trapped within the filter medium surface at any time during operation, realize working continuously.But vacuum filter is the motive force of negative pressure as filtration, and filter capacity is low, is suitable for the suspension that solids content is few, flow is little and implements Separation of Solid and Liquid.
The operation principle of belt filter press is: after fully mixing in quiet, dynamic mixer through the mud that concentrates and certain density flocculant, the small solid particle coacervation in the mud becomes the bigger cotton-shaped agglomerate of volume, isolates Free water simultaneously; Mud after the flocculation is transported on the strainer that concentrates gravity dehydration; Free water is separated under the effect of gravity, forms the not mud of flow regime, is clamped in then up and down between two guipures; Under the ascending extruding force in wedge shape precompressed zone, low-pressure area and higher-pressure region, shearing force effect; Progressively push mud,, form filter cake at last and discharge to reach maximum mud, separated form water.Belt filter press belongs to intermittent duty, is confined to the squeezing of mud class, can not be used for liquid filtering.
The operation principle of horizontal spiral filter press is: rotary drum and spiral are with the rotation at a high speed in the same way of certain differential; Material is introduced defeated material spiral inner core continuously by feed pipe; Quicken the back and get into rotary drum, under effect of centrifugal force, heavier solid formation is deposited on and forms filter cake layer on the rotatory drum wall.Defeated material spiral successively is pushed into rotary drum awl end surely with the solid formation of deposition, and outside slag-drip opening discharge machine, lighter liquid phase thing then forms the internal layer pendular ring, overflows rotary drum continuously by the big end overfall of rotary drum, outside leakage fluid dram discharge machine.The horizontal spiral filter press can be worked continuously, owing to be to lean on the centrifugal formation filter cake layer of gravity, solid proportion must could form filter cake layer greater than liquid specific gravity.The liquid suspension that therefore can not be used to not have the branch of proportion separates, so there is not reliable filter efficiency.
More than be various filter presses because insufficiency of function, forming with the liquid filtering is main equipment, does not have filter residue squeezing and excretory function, the equipment with squeezing and excretory function, no liquid filtering function.The equipment that reliable liquid filtering efficient is arranged can not be worked continuously.The equipment that can work continuously, it is low not have reliable filter efficiency or performance.Various device is confined to the field that adapted to, does not have a kind of equipment to use in the various fields of omnibearing adaptation, does not also have a kind of equipment to can be used in industrial products production process and sewage disposal process, in closed cycle, implements the solid-liquid body and separates.The filter medium that existing in addition solid-liquid body separation equipment uses is: filter cloth, filter membrane, all belonging to consumable accessory, both do not had stable filtering accuracy, also is the prime cost of solid-liquid body separation equipment operation.
