Description
Technical field
The present invention relates to a kind of centrifuge, be specifically related to the pre-enrichment type of a kind of material screw unloading filter centrifugal machine.
Background technology
Centrifuge is that the centrifugal inertial force that utilizes drum rotating to produce is realized the separation of suspension, emulsion and other heterogeneous material or concentrated machine.
Centrifuge has many types, divide by its separation process to material, mainly contain two kinds of unpack formats of filtering type and decanter type, filtering type and sedimentation-type centrifuge branch out again a variety of types, separation process by centrifuge divides, and is divided into two kinds of continous way and batch (-type)s; Operating process by centrifuge divides, and is divided into again two kinds of self-action and hands; Divide by the centrifuge drive mechanism, be divided into again two kinds of two supports and cantilever support; Orientations of major by centrifuge is divided, and is divided into again vertical and horizontal two kinds.
Screw unloading filter centrifugal machine is that at present both at home and abroad the most general a kind of continous way is with the centrifuge of screw unloading function, it is by perforate bowl, screw feeder, differential mechanism, feed arrangement, wash mill, lubricating system, transmission system, dynamical system, casing, the composition such as support and damping base, its operation principle is: motor is by two groups of belt pulley transferring power, drive respectively perforate bowl and screw feeder with certain poor rotating speed same-directional high-speed rotation, material is introduced the screw feeder inner core continuously by feed pipe, enter perforate bowl after the acceleration, under the effect of centrifugal force field, liquid phase is discharged perforate bowl by the filter medium screen cloth, and through mother liquor pipe outflow centrifuge, solid formation is trapped within and forms filter residue in the perforate bowl, filter residue is under the acting in conjunction of centrifugal component and conveying spiral, continuously the small end by perforate bowl throws away to large end movement, and through the blowpit discharge centrifuge, screw unloading filter centrifugal machine can continuous feed under the full-speed operation state, separate, washing and discharging have compact conformation, volume is little, continued operation, smooth running, the characteristics such as the large and filter residue water capacity for the treatment of capacity is low.
Screw unloading filter centrifugal machine is applicable to the solid phase particles granularity greater than 0.10mm, solid concentration is greater than 25% coarse crystallization and the Separation of Solid and Liquid of short fiber material, but because the filter medium of this centrifuge is metal lath, adopt punching, the photoelectricity corrosion, the methods such as laser perforation process at metal book plate, for guaranteeing the intensity of net, the percent opening of general net is all about 5%, so it requires more than 25% the material solid concentration, I haven't seen you for ages causes filter residue moist for solid concentration, sub-argument is unclear, the few texts of output, a lot of materials are because be subjected to process technology limit can't reach the solid concentration requirement, also just can't reach instructions for use, so also just greatly limited the application of this centrifuge on a lot of materials.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, a kind of screw unloading filter centrifugal machine is provided, by a centrifugal basket is set the low material of solids content is efficiently separated, greatly reduce water content and the later stage dry materials energy consumption of filter residue, improve applicability and the Integrated using effect of centrifuge.
For solving above technical problem, the present invention takes following technical scheme:
The pre-enrichment type of a kind of material screw unloading filter centrifugal machine, comprise support and the fuselage and the casing that are arranged on the support, the support bottom is provided with damping base, the lubricating system that is provided with transmission system in the fuselage and matches with transmission system, and the spiral perforate bowl and the screw feeder that are connected and are driven by the transmission system differential, be provided with the feed pipe that enters screw feeder for material on the casing, between the outlet of feed pipe and screw feeder, be provided with centrifugal basket, centrifugal basket is conical, and the less end in its cross section is connected with the outlet of feed pipe.After material enters centrifuge from feed pipe, at first enter centrifugal basket and separate, filtrate is discharged from apocenosis passage, reaches the effect of enrichment, and simultaneously, the solid-phase material in the centrifugal basket is discharged mutually with remaining filter and is entered the spiral perforate bowl.
The present invention compared with prior art has following advantage:
Material at first enters centrifugal basket by feed pipe, utilize the centrifugal filtration principle to break away from partially liq, realize the material enrichment, the material of enrichment is transported to the spiral perforate bowl and carries out last dehydration subsequently, the filtered fluid in two stages discharges respectively, because having carried out pre-enrichment processes, be equivalent to increase the length of rotary drum, area and the material movable length of dehydration have been improved, make the reduction of the water content maximum possible of filter residue, can also reduce simultaneously the later stage energy consumption for drying of material, improve applicability and the Integrated using effect of centrifuge.
