This pair of spiral shell solid-liquid separating machine, described " 8 " font screen pack adopts rigid macromolecule precise microfiltration material, such as ferrotitanium, NiTi, copper titanium etc., filtering accuracy and filter efficiency are very high, filtering accuracy is 20 ~ 80 microns, and chemical property is very superior, can resistance to most of acid, alkali, salt and most of organic solvent, in more than 2 to five years filter material life-span, belong to long-acting filter material.The center of described folded spiral shell filter is provided with " 8 " word installing hole suitable with " 8 " font screen pack size shape, the folded each side of spiral shell filter is set to inside spill, play the effect of material-saving, folded spiral shell filter corner is provided with axis hole, folded spiral shell filter comprises multiple monolithic filter and is formed by connecting by installing tie bar in axis hole, and the distance between adjacent two monolithic filters is 0.6 ~ 1.2mm.Described twin-screw is that synchronous backward rotates, and the screw thread displacement of twin-screw is divergence form structure, and the material of twin-screw is the alloy bimetal material of antiacid caustic corrosion, adopts two spiral shell extruding can accelerate filtrate separation process, greatly reduces moisture content, improve production capacity.The angle of inclination of described sealing liquid storage cylinder is 30-60 °.The backwashing manner that described sealing liquid storage cylinder inside adopts, for just rinsing or backwash, is describedly just rinsing as installing flusher outside folded spiral shell filter, and described backwash be at twin-screw inner installation flusher.
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.
Accompanying drawing explanation
Accompanying drawing 1 is the monnolithic case structural representation of the two spiral shell solid-liquid separating machine of the present invention.
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 20 ~ 80 microns.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 0.6 ~ 1.2mm.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.
This pair of spiral shell solid-liquid separating machine, gearbox 4 adopts Pyatyi speed governing dynamical system, equipment low cruise, and power needs little, and equipment operates steadily, and the equipment attrition degree caused gently improves service life of equipment greatly.Sealing liquid storage cylinder 1 adopts totally enclosed running, and pollution-free, peculiar smell and noise ensure the safety of producing, protection working environment and personal safety.When equipment runs, filtrate separation is accelerated in the extruding of twin-screw 9 synchronous backward, after folded spiral shell filter 7, sealing liquid storage cylinder 1 is entered after liquid is leached by " 8 " font screen pack 8, store after liquid outlet 3 through sealing liquid storage cylinder 1 bottom flows out, and filter mud moves upward and to discharge by sealing the mud mouth 2 on liquid storage cylinder 1 top under the promotion of twin-screw 9.
