The invention has the beneficial effects as follows: this pair of spiral shell solid-liquid separating machine, improves filtering accuracy, filter efficiency and service life, reduces energy consumption, material consumption and cost, simultaneously easy to operate, unload dry filter cake convenient, regeneration is convenient, is suitable for applying on a large scale.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is the monnolithic case structural representation of the two spiral shell solid-liquid separating machine of the present invention.
Accompanying drawing 2 is the A-A cross-sectional schematic in Fig. 1 of the present invention.
In figure, 1 sealing liquid storage cylinder, 2 mud mouths, 3 liquid outlets, 4 gearboxes, 5 motors, 6 axis holes, 7 folded spiral shell filters, 8 " 8 " font screen packs, 9 twin-screws.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This pair of spiral shell solid-liquid separating machine, it is characterized in that: comprise the sealing liquid storage cylinder 1 tilting to install, the top and bottom of sealing liquid storage cylinder 1 are respectively equipped with mud mouth 2 and liquid outlet 3, sealing liquid storage cylinder 1 inside is provided with " 8 " font screen pack 8, coordinate outside " 8 " font screen pack 8 and folded spiral shell filter 7 is installed, " 8 " font screen pack 8 inside is provided with the twin-screw 9 be engaged mutually, and twin-screw 9 lower end is connected with gearbox 4, and gearbox 4 is connected with motor 5.Described " 8 " font screen pack 8 adopts rigid macromolecule precise microfiltration material, and filtering accuracy is 10-100 micron.The center of described folded spiral shell filter 7 is provided with " 8 " word installing hole suitable with " 8 " font screen pack 8 size shape, the folded each side of spiral shell filter 7 is set to inside spill, folded spiral shell filter 7 four jiaos is provided with axis hole 6, folded spiral shell filter 7 comprises multiple monolithic filter and is formed by connecting by installing tie bar in axis hole 6, and the distance between adjacent two monolithic filters is 0.5-1.5mm.Described twin-screw 9 rotates in synchronous backward, and the screw thread displacement of twin-screw 9 is divergence form structure, and the material of twin-screw 9 is the alloy bimetal material of antiacid caustic corrosion.The angle of inclination of described sealing liquid storage cylinder 1 is 30-60 °.The backwashing manner that described sealing liquid storage cylinder 1 inside adopts, for just rinsing or backwash, is describedly just rinsing as installing flusher outside folded spiral shell filter 7, and described backwash be at twin-screw 9 inner installation flusher.
