Description
Technical field
The utility model relates to the oil equipment field, relates in particular to a kind of leaching type oil equipment, and a kind of pressing screw of extraction material extruder is pressed the thorax structure specifically.
Background technology
At present, known extraction precipitation technique is: material drains behind extraction, directly advances afterwards drying machine drying.Owing to being drained the time and restrictions process conditions, the water capacity in the material generally about 80 ﹪, a large amount of steam consumption when having caused solvent recovery.Existing desolventizing equipment for material behind the extraction is on the basis of existing oil plant pre-squeezer the body seal transformation to be formed, its press sections is grouped into by pressing screw and press for extracting juice thorax, material enters the press for extracting juice thorax by feed bin, and pressing screw is pushed material under main shaft drives.
Because the pressing screw compression ratio is generally 7～10, compression ratio is larger, causes machine utilization large, and power consumption is large; First order pressing screw just begins squeezing in addition, so that press for extracting juice thorax inlet pressure is higher, the material that water capacity is large can't enter the press for extracting juice thorax.Such pressing screw is pressed the thorax structure and is had the low shortcoming of material treatment effeciency.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of easy to use, treatment effeciency is high, the pressing screw that can reduce the continuously extruded type extraction material extruder of power consumption is pressed the thorax structure, on this basis, also provide a kind of pressing screw press for extracting juice thorax structure that the large material of water capacity can't enter the extraction material extruder of the problem of pressing thorax that solves.
The technical solution of the utility model is, a kind of pressing screw of extraction material extruder is pressed the thorax structure, comprise and press thorax, be positioned at and press thorax and be located at pressing screw on the main shaft, described pressing screw is provided with the N level, N is 〉=2 natural number, the one-level pressing screw refers to be located at one section continuous pressing screw on the main shaft, is provided with interval parts between the described pressing screws at different levels, along be fed to discharging direction material by pressing screws at different levels after overall compression ratio increase step by step.
Adopt technique scheme, along be fed to discharging direction material by pressing screws at different levels after overall compression ratio increase step by step, thereby material is formed continuous compression, overall compression ratio doubly is reduced to 2-6 doubly by 7-10, solvent in the material is extruded via pressing thorax, so that contained solvent is reduced in the material, because after material enters pressing screw press for extracting juice thorax structure, to improve step by step its overall compression ratio, just realized continuous feed, improve the treatment effeciency of material, reduced the equipment operating load, reduced power consumption.
As improvement, described material by pressing screws at different levels after overall compression ratio increase step by step and refer to, reduce step by step and/or the internal diameter that presses thorax reduces step by step and/or the external diameter of main shaft increases step by step along the pitch that is fed to discharging direction pressing screw.This improvement project, pressing screw are the integral type structure, and the pitch by pressing screw reduces step by step and/or the internal diameter that presses thorax reduces step by step and/or the external diameter of main shaft increases step by step, the pressing screw space is reduced step by step, thereby overall compression ratio is increased step by step.
As preferably, described pressing screw comprises the spire on swivel nut and the swivel nut, and described pressing screw fixedly is assemblied on the main shaft by swivel nut, and described interval parts is the spacer ring that is set on the main shaft.Pressing screw is that mode by fixing assembling is fixed on the main shaft in this preferred version, is different from above-mentioned integral structure, and such assembling mode is so that the installation of pressing screws at different levels and keep in repair more convenient, practical.
As improvement, described material by pressing screws at different levels after overall compression ratio increase step by step and refer to, reduce step by step and/or the internal diameter that presses thorax reduces step by step and/or the swivel nut external diameter of pressing screw increases step by step along the pitch that is fed to discharging direction pressing screw.Adopt this improvement project, by adjusting the pitch that fixedly is assemblied in the pressing screw on the main shaft, the internal diameter that presses thorax, the swivel nut external diameter of pressing screw, the pressing screw space is reduced step by step, thereby overall compression ratio is increased step by step.
As preferably, the scope of the quantity N of described pressing screw is 4～10, and described the first pressing screw is the charging pressing screw, and the 2nd～N pressing screw is the compression pressing screw.Adopt this preferred version can adjust according to what and water capacity of material the design quantity of pressing screw, the first pressing screw is that the charging pressing screw is not compressed, solved press for extracting juice thorax inlet pressure higher, the material that water capacity is large can't enter the problem of pressing thorax, by the 2nd～N pressing screw compression ratio being increased to 2～6 times step by step, to have solved machine utilization large, the problem that power consumption is large.
As preferably, the swivel nut of described pressing screw and the fixedly assembling mode of main shaft be key be connected or be welded to connect in a kind of.Adopt flat key to connect in this preferred version or the mode of welding can realize that all pressing screw rotates with the rotation of main shaft, two kinds of connected modes can realize that all it presses effect in the thorax structure in whole pressing screw.
As preferably, when the swivel nut external diameter of adjacent pressing screw is identical, spacer ring be shaped as the annular cover identical with pressing screw swivel nut external diameter, the swivel nut external diameter of adjacent pressing screw not simultaneously, spacer ring be shaped as the frustoconical cover with certain taper.Adopt the annular cover when swivel nut external diameter of adjacent pressing screw is identical in this preferred version, external diameter does not adopt the frustoconical cover with certain taper to play the effect of excessive connection simultaneously.
In sum, the beneficial effect that the utility model compared with prior art produces is: reduced the equipment operating load, reduced power consumption, charging is convenient continuously, improved the treatment effeciency of material, realize simultaneously the reduction of the solvent of material, so that the steam that the later stage drying course consumes minimizing, so that the operating pressure of subsequent process drying condensation device is reduced, weaken the consumption of solvent, had good popularizing value.
