The specific embodiment
Below in conjunction with accompanying drawing content of the present invention is further specified.
As shown in Figure 1, 2, urceolus comprises that bottom screen cloth 19, transition cone section 16 consist of with sealing cylinder 15 3 parts, top has the upper end that semicircle opening, bottom have the bottom screen cloth 19 of sieve aperture and is connected by transition cone section 16 and sealing tins 15, transition cone section 16 is all-round enclosed construction, sealing cylinder 15 also is all-round enclosed construction, screen cloth 19 upper ends, bottom are bored between section 16 1 ends with transition and are connected by means of flange, be welded to connect between the lower end of transition cone section 16 other ends and sealing cylinder 15, the lower end of bottom screen cloth 19 is connected, seals cylinder 15 with flange upper end is connected with flange.King bolt axle 17 is equipped with in screen cloth 19 centers, bottom, king bolt axle 17 is provided with constant pitch helical blade 18, the helical blade diameter of constant pitch helical blade 18 has determined the process lot size of slurry slag separator substantially, can be equipped with different helical blades according to the demand of production line.In one embodiment, helical blade diameter 1000mm.The lower end of king bolt axle 17 is installed on 19 times end flanges of bottom screen cloth by means of bearing, and is connected the realization sealing with flange by end cap.The upper end of king bolt axle 17 is connected with minor spiral axle 10 lower ends by means of screw, is welded with change helical blade 11 on the minor spiral axle 10, and becoming helical blade 11 optimum states is that compartment becomes spiral, and namely the pitch variation tendency is large-little-large-little replacing.Minor spiral axle 10 is positioned at transition cone section 16 and sealing cylinder 15 centers.Epimere, the hypomere of sealing cylinder 15 are the individual layer barrel, and the stage casing is double-decker, and close on the middle section at epimere and have ring-type discharging opening 9.The stage casing internal layer of sealing cylinder 15 is that squeezing screen cloth 14, the skin of mesh structure is the cylindrical shell 28 of closed structure.Rinse mouth 12 is offered on the outer wall top of cylindrical shell 28, the lower end sets out the mouth of a river 13.
Also be welded with thinner blade-like thin plate on the minor spiral axle 10 in sealing cylinder 15, also broken blade can be welded on sealing cylinder 15 inwalls, with helical axis rotation, helical blade does not adopt interrupted structure to blade, can play equally the effect of the article such as in course of conveying shredded plastic bag.
After bottom screen cloth 19, transition cone section 16 and 15 assemblings of sealing cylinder, become 35 degree angle inclined types to be installed on the slurries collection tank 20 with the level ground, and be fixed in the collection tank 20 by means of gusset.Supporting leg 21 is supported on sealing cylinder 15 middle sections.Supporting leg 21 adopts sleeve or track adjustable structure.
The output shaft of motor 1 is connected with the power shaft of decelerator 2, and the output shaft of decelerator 2 is connected by means of the top of shaft coupling 3 with minor spiral axle 10.
The course of work: motor 1 by decelerator 2 and shaft coupling 3 with transmission of power to minor spiral axle 10 and king bolt axle 17, minor spiral axle 10 drives variable-pitch auger blades 11 rotary squeezings, king bolt axle 17 drives constant pitch blades 18 rotary squeezings.The changing food waste that constant pitch helical blade 18 is come conveying is upwards carried, and part water and grease flow into slurries collection tank 20 by bottom sieve aperture 19 under action of gravitation in the process of carrying; The changing food waste of carrying enters in the all-round sealing cylinder 15 through all-round transition cone section 16, and changing food waste is bored the extruding force effect that section 16 is subject to variable-pitch auger blade 11 in transition, and the slurries such as moisture and grease are extruded and flow in the collecting box 20.The double-decker in sealing cylinder 15 stage casings, the squeezing screen cloth 14 of internal layer barrel, changing food waste is in the course of conveying that makes progress, because the volume between variable-pitch auger blade 11 each blade changes, so changing food waste is subject to the squeezing action of blade in course of conveying, the water that squeezes out and grease flow into slurries collecting box 20 from delivery port 13 through flexible pipe.Variable-pitch auger blade 11 optimum states on the minor spiral axle 10 are that compartment becomes spiral, and the pitch variation tendency is large-little-large-little replacing, the changing food waste that contains a large amount of polybags is subject to extrusion dehydration one time when becoming fine pitch by coarse pitch, when becoming king bolt, minor spiral obtaining discharging upset, adjust its locus, again when king bolt becomes minor spiral, be subject to for the second time extruding, can make like this changing food waste obtain omnibearing extrusion dehydration.Also be welded with thinner blade-like thin plate on the minor spiral axle 10, it can play the broken effect of tearing to being entrained in the foreign material such as wherein polybag, cloth in rotary course, reduces the bag axle occurs to twine the possibility that causes stall; Selectablely broken blade can be welded to sealing cylinder 15 inwalls, blade does not rotate with the axis, and helical blade adopts interrupted structure, can play equally the effect of the article such as in course of conveying shredded plastic bag.Back pressure cone 5 is pressed on discharging opening 9 places of sealing cylinder 15 by 3 back pressure springs 6, because the pretightning force effect of back pressure spring 6, carry the changing food waste that comes up to overcome pretightning force through helical blade 11 and just can push back pressure cone 5 open from discharging opening 9 dischargings, in this process, the further screenings of back pressure cone 5 pressure that provide is provided changing food waste separates.Back pressure spring 6 back pressures can regulate 22 by adjusting screw(rod), and back pressure can be measured in real time through power sensor 7.There is supporting leg 21 outside of sealing cylinder 15, on the supporting leg 21 adjusting device is arranged, and can adjust setting angle and charging aperture 9 height by adjusting device, thereby adapt to different field working conditions.Rinse mouth 12 is used for hole flushing on the squeezing screen cloth 14 on the sealing cylinder 15 stage casing cylindrical shells 28, prevents that sieve screen apertures from stopping up.
