Description
Technical field
The present invention relates to the energy-conservation fed technology of sheet frame class solid-liquid separating equipment field, be specifically related to a kind of energy-saving solid state feed arrangement and method thereof based on filter press feedstock characteristic.
Background technology
Traditional sheet frame class filter press, such as plate type pressure filter, adopts screw pump, membrane pump etc. to carry out charging more.
The advantage of screw pump is: 1) pressure and range of flow are broad, and pressure is about 3.4-340 kilogram/square centimeter, and flow can reach 100 cubic centimetres/minute; 2) transport kind and the range of viscosities broadness of liquid; 3) because the pivoting part inertia force in pump is lower, therefore can use very high rotating speed; 4) intake performance is good, has suction capacity; 5) flow is evenly continuous, vibration, and little noise is low; 6) compare with other drum pump, not too responsive to the gas entering and dirt; 7) sturdy construction, installs maintenance easily.
The advantage of membrane pump is: 1) owing to being used as power with air, so flow is adjusted automatically with the variation of back pressure (resistance to flow output), be suitable for the fluid of medium-high viscosity.And water be take as benchmark sets in the operating point of centrifugal pump, if for the slightly high fluid of viscosity, need supporting reductor or variable-frequency governor, cost has just improved greatly, for gear pump, is also so same; 2) reliable and cost is low with air driven pump in inflammable and explosive environment, as the conveying of fuel, gunpowder, explosive, because: the first, after ground connection, can not produce spark; The second, in work, empty calory produces, and machine can be not overheated; Three, fluid can be not overheated because the stirring of membrane pump convection cell is minimum; 3) the severe place in building site, as the discharge of wastewater of construction site, industrial and mineral, because the impurity in sewage is many and complicated component, pipeline is easy to stop up, and like this electric pump is just formed to the too high situation of load, the motor feels hot rapid wear.Pneumatic diaphragm pump can be adjustable by particle and flow, automatically stops to unobstructed during line clogging; 4) can be used for carrying the more unsettled fluid of chemical property, as: photosensitive material, flocculation liquid etc.This is because the shearing force of membrane pump is low, little to the physical influence of material; 5) in having harmfulness, the processing of corrosive material, membrane pump can separate material and the external world completely; 6) or in some tests guarantee not have contaminating impurity raw material; 7) little being easy to of membrane pump volume moved, and do not need ground, and occupation of land face is minimum, simple installation economy.Can be used as movable object material conveying pump.
The feed pump of more than enumerating is the normal pump using of press filtration industry, but the material of spininess to moisture content 95%-99%, when material water ratio is low when the 60%-80%, just need the expensive solid-state delivery pump of special use to carry, current sheet frame kind equipment yet there are no realizes charging in this way.Such as municipal sludge or the seaweed mask raw material of low-water-content, in the use procedure of conventional feeds pump loss very large, efficiency is extremely low.This just causes huge power consumption and stand-by equipment a large amount of idle running and fault.
