The invention relates to a scraping and sucking device in a centrifuge, which comprises a scraper (1), a scraper holder (2) and a driving cylinder (8). The scraper holder (2) is internally provided with a shaft (3) which can move up and down; the inner cavity of the shaft (3) is provided with a through hole; the inner cavity formed on the upper end of the scraper holder (2) is internally provided with a worm (6) which is meshed with a worm wheel (7) sleeved on the shaft (3); a guiding sleeve (4) is fixed on the upper end of the shaft (3); the piston rod of the driving cylinder (8) is connected with the guiding sleeve (4) through a connecting rod (9); the excircle of the shaft (3) is provided with at least one guiding slot; guiding splines (5) arranged in the guiding slots in a sliding way are matched with the guiding sleeve (4); the bottom end of the shaft (3) is provided with the scraper (1); the scraper (1) is provided with a blade (11) and a sucking port (12); and one end of the worm (6) is provided with a hand wheel (10). The scraping and sucking device in the centrifuge is simple in structure, can suck out the materials when scraping and is convenient to use. Due to the adoption of the scraping and sucking device in the centrifuge, the work efficiency is improved, and the labor intensity is reduced.
Description
Technical field:
The present invention relates to centrifuge, especially relate to the scraper device for suction material in a kind of centrifuge.
Background technology:
Centrifuge is a kind of machinery that utilizes centrifugal force to carry out Separation of Solid and Liquid, and at present, the centrifuge with cutter discharge of solid that great majority adopt is all unloading under scraper mode, after feed separation, scraper discharging, material is discharged from the material-dropping hole of bottom, and this is higher to factory building height space requirement; Also have now part producer after separation finishes, with instrument, by smashing to pieces under the material scraper on internal filtering in rotating drum cloth, with vaccum suction pipe, material is sucked out afterwards, this method automaticity is poor, and labour intensity is large, and the work period is long.
Summary of the invention:
The object of this invention is to provide the scraper device for suction material in a kind of centrifuge, the problem that it can solve, and centrifuge discharging automaticity is poor, labour intensity is large, the work period is long.
The problem that will solve required for the present invention realizes by the following technical solutions: the scraper device for suction material in a kind of centrifuge, comprise scraper, scraper base and driving cylinder, it is characterized in that: in scraper base, be provided with axle moving up and down, axle inner chamber is set to through hole, in the inner chamber that scraper base upper end forms, be provided with worm screw, and mesh with the worm gear being enclosed within on axle, axle upper end is fixed with fairlead, the piston rod of driving cylinder is connected with fairlead by connecting rod, the cylindrical of described axle is provided with at least one gathering sill, the feather key being slidably arranged in gathering sill matches with axle, the bottom of axle is provided with scraper, described worm screw one end is provided with handwheel.On described scraper, be also provided with blade and material sucking port, the cutting edge of blade is provided with several recesses.
The present invention adopts above-mentioned structure, under the drive of driving cylinder, scraper is lifting in rotary drum, shaking handwheel can chip away the material scraper in rotary drum, under the effect of pull of vacuum, scrape the material that the chips away material sucking port from scraper and release by the hole in axle, convenient and swift, automaticity is high, has improved operating efficiency.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention
Fig. 2 is the cutaway view of A-A of the present invention
Fig. 3 is the enlarged drawing of C part in Fig. 2
Fig. 4 is the profile of wing in the present invention
Fig. 5 is that D in Fig. 4 is to view
In Fig. 1 to 5: 1, scraper 2, scraper base 3, axle 4, fairlead 5, feather key 6, worm screw 7, worm gear 8, driving cylinder 9, connecting rod 10, handwheel 11, blade 12, material sucking port 13, recess 14, rotary drum
The specific embodiment:
From Fig. 1 to Fig. 5, scraper device for suction material in a kind of centrifuge, comprise scraper 1, scraper base 2 and driving cylinder 8, in described scraper base 2, be provided with axle 3 moving up and down, described axle 3 inner chambers are set to through hole, in the inner chamber that the upper end of scraper base 2 forms, are provided with worm screw 6, and mesh with the worm gear 7 being enclosed within on axle 3, axle 3 upper ends are fixed with fairlead 4, and the piston rod on driving cylinder 8 is connected with fairlead 4 by connecting rod 9; The cylindrical of described axle 3 is provided with at least one gathering sill, and the feather key 5 being slidably arranged in gathering sill matches with axle 3, and the bottom of axle 3 is provided with scraper 1, is provided with blade 11 and material sucking port 12 on scraper 1, and the cutting edge of blade 11 is provided with several recesses 13; Described worm screw 6 one end are provided with handwheel 10.During concrete enforcement, axle 3 tops are connected with outside vacuum-pumping tube, driving cylinder 8 action live stopper rods decline, by connecting rod 9, drive fairlead 4 and axle 3 to decline, when declining, slowly shake handwheel 10, under the effect of worm screw 6, worm gear 7 and feather key 5, make the inwall of the blade 11 slowly close rotary drums 14 on scraper 1, scrape fallen material and suck in axles 3 and from its top and pass through vacuum-pumping tube sucking-off from material sucking port 12, scraper is complete, driving cylinder 8 resets, shake handwheel 10, make scraper 1 away from rotary drum 14, get back to initial position.By material sucking-off, convenient and swift in scraper, automaticity is high, has improved operating efficiency.
Obviously; the above embodiment of the present invention is only for example of the present invention is clearly described; but be not used for limiting the scope of the invention, all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be limited by every claim.
