Detailed description of the invention
In changing food waste processing procedure, carrying out before solid changing food waste is separated with liquid changing food waste, need first to carry out crushing operation to whole changing food wastes, conventional crushing technology has rotor hammer type crushing technology and double-roll type crushing technology, but be subject to changing food waste oneself viscosity and concentration on the impact of crushing effect, through the solid changing food waste pulverized and after Separation of Solid and Liquid, its solid humidity still cannot meet the humidity requirement to solid changing food waste in fermentation treatments, need to carry out the operation of conveying extruding crushing/dewatering to the solid changing food waste after Separation of Solid and Liquid further.
Shown in composition graphs 3, Fig. 4, lift tank is pulverized in the extruding of geometric ratio pitch auger, comprises and promotes casing 1, helical feed pressurizing unit, reducing mechanism and drive unit.
Promote casing, be obliquely installed upward, promote the charging aperture 11 place height of casing lower than discharging opening 12 place height, in the process of conveying solid substance changing food waste obliquely upward, make the raffinate be mixed with in solid changing food waste, be convenient to automatically flow down from the base plate 13 promoting box inside.
Helical feed pressurizing unit, is arranged on lifting box house, in the process of convey materials, carry out extrusion dehydration operation to material simultaneously.Helical feed pressurizing unit, comprise a main shaft 20 and a countershaft 21, main shaft and countershaft be arranged in parallel, corresponding respectively on main shaft and countershaft two groups of helical blades are set, namely be positioned at the first helical blade set 30 of spindle front and be positioned at second helical blade set 31 at main shaft rear portion and be positioned at the first helical blade set 30 of countershaft front portion and be positioned at second helical blade set 31 at countershaft rear portion, between the inner each helical blade of first helical blade set 30, pitch is equal, pitch scaled down between the inner each helical blade of the second helical blade set 31.Wherein, main shaft or countershaft front portion, referring to the end near promoting casing charging aperture, main shaft or countershaft rear portion, referring to the other end near promoting casing discharging opening.Base plate upper shed at the charging aperture place of lifting casing is also provided with screen pack 4, for leaching the raffinate in material conveying process.
The rotation of main shaft 20, controlled by drive unit, countershaft 21 is driven shaft, in the process that main shaft 20 rotates, be separately positioned on two group of first helical blade set 30 of spindle front and countershaft front portion, play the effect of conveying solid substance changing food waste, because between the inner each helical blade of the first helical blade set, pitch is equal, therefore, the solid changing food waste in course of conveying is not played to the effect of extrusion dehydration, this is because screen pack is arranged on the below of two group of first helical blade set 30 just, if changing food waste just starts extruding at charging aperture place, charging aperture place solid changing food waste is easily made to gather too much, blocking screen pack, affect the osmotic effect of screen pack.
Pitch scaled down between the inner each helical blade of two group of second helical blade set 31 being arranged on main shaft rear portion and countershaft rear portion, solid changing food waste is followed in main axis process and is progressively extruded dehydration, simultaneously, flow down along the raffinate squeezed out in solid changing food waste along the inner side base plate 13 promoting casing, and discharged by the screen pack 4 promoting casing charging aperture place, and the solid particle retained on screen pack, then can follow main axis and again obtain conveying hoisting.
Reducing mechanism, be arranged on helical feed pressurizing unit rear, extruding crushing operation is carried out to the material after helical feed pressurizing unit, due to the solid changing food waste after helical feed pressurizing unit extrusion dehydration, solid humidity obviously reduces, and is beneficial to the crushing effect improving reducing mechanism.Reducing mechanism, comprise the first bevel gear 60 and the second bevel gear 61 be separately positioned on main shaft 20 and countershaft 21, disintegrating area is extruded between first bevel gear and the second bevel gear, extruding crushing operation is carried out to the material after described helix transporting device extrusion dehydration, material after extruding crushing operation, meet fermentation requirement, discharge from the discharging opening promoting casing, in the outside of the first bevel gear and the second bevel gear, a knife plate 5 is set respectively, described in cooperation first, second bevel gear 60, 61 carry out extruding crushing operation, knife plate 5 is fixed on described lifting casing 1.In the process of extruding crushing operation, also can squeeze out a little raffinate, flow down along the inner side base plate 13 promoting casing.
Drive unit, is arranged on and promotes outside casing 1, for providing Power output for helical feed pressurizing unit and reducing mechanism.Drive unit, comprises drive motors and sprocket wheel, and one of them sprocket wheel 7 is connected with main shaft 20, drives described main axis.
Certainly; more than illustrate and be only preferred embodiment of the present invention; the present invention is also not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this description; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this description, protection of the present invention ought to be subject to.
