The filter residue conveying device of the filter residue output system of equipment for separating liquid from solid is installed on the Equipment Foundations below the equipment for separating liquid from solid slagging device, can adopt the form conveying equipments such as belt, series connection scraper plate or spiral of market sale, belong to the market prior art, do not draw among the figure.

The pipe-line system and the operation method of equipment for separating liquid from solid of the present invention are as follows:

The present invention utilizes the principle of filter chamber transfiguration squeezing to finish Separation of Solid and Liquid, and base program comprises the charging filtration stage, extrusion filtration stage, squeezing stage, deslagging stage; The charging filtration stage is to realize conventional art in present device, has not described at this.

The program of the present invention's innovation is extrusion filtration stage, squeezing stage, deslagging stage.

The extrusion filtration stage: the stoste that will filter is passed through valve with pump, the stoste distribution tank, pressure hose, former fluid valve and distribution nozzle G1 enter into and the filter element that is communicated with on the filter pulp of screen pipe unit indoor, at this moment residual cake valve is in the closed position, cleaner liquid flows down along the sieve aperture that rigid filaments weaves conveyer belt through the hole of tubulose filtering medium under the effect of raw liquor pump pressure, and filter residue (solid content) is trapped in the filter pulp chamber, start cable traction mechanism simultaneously, piston is scraped the slag cable and is begun to draw the piston scum board and move back and forth, piston scum board assembly is in the basic horizontal state when moving along the filter pulp flow direction, filter residue scrapes from membranous wall under the sliding-contact effect of piston scum board assembly, be slipped to end, filter pulp chamber, begin commutation after piston scum board assembly arrival end is spacing, the contrary filter pulp flow direction of commutation back piston scum board assembly moves, the left side of piston scum board assembly, right two lobe piston scum boards upset becomes the vertical axis inclination certain angle with the filter pulp chamber, do not scrape slag as far as possible, so repeatedly deslagging is pooled to bottom, filter pulp chamber, when cleaner liquid stream reduces to 10～80% of original flow, closing former fluid valve stops for stoste, cable traction mechanism rests on the filter pulp chamber piston scum board assembly or the bottom, pressing plate moves on the slide rail on the frame side members of the effect lower edge of compression system, pressure is passed to the filter element that is arranged in rows successively by middle bearing plate, distance between each filter element constantly shortens, pressing plate, middle bearing plate and bearing plate are to the excircle two sides extruding of the tubulose filtering medium at middle part, screen pipe unit, flexible tubulose filtering medium is flattened, this moment, the material liquid passage that advances to filter of screen pipe unit was also closed, under the constant prerequisite of girth, the cylindrical of the axially middle cross section of screen pipe unit becomes length behind the pressurized, the bigger approximate rectangular ellipse of short diameter gap, compression system sets back subsequently, opening former fluid valve again continues to filter for filtering stoste and starting cable traction mechanism, so repeatedly: enter stoste-startup cable traction mechanism and realize that thin bed filtration-extrusion-the filter residue mass concentration constantly is increased to optium concentration in the indoor stoste of filter pulp, for example 15%, finishing extrusion and filtering.

The squeezing stage: compression system continues minimizing filter pulp chamber, compression screen pipe unit volume and enters the squeezing stage, and squeezing only is squeeze force greater than compressive force with the difference that extrusion is filtered, and filter residue becomes filter cake and finishes filtration duty.
