The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1 and Figure 2, scraper in centrifuge described in the utility model, comprise casing 1, the interior rotation of casing 1 is provided with guide 2, casing 1 is stretched out in the upper end of guide 2, in guide 2, be provided with and can endwisely slip and can radially not do cross section in relative rotation along guide 2 and for the lower end of the first tooth bar 3, the first tooth bars 3 of circle, stretch out guide 2 and be provided with scraper 4, the first tooth bar 3 upper ends and be arranged with case 21 along guide 2.A radially side of described casing 1 is provided with gear-box 5, in gear-box 5, be at least provided with two pitch wheels---driving gear 6 and driven gear 7, when actual production, several travelling gears 8 can be increased between driving gear 6 and driven gear 7, for eliminating transmission stress.Driven gear 7 and the first tooth bar 3 engagements, the lower end that the left side of driving gear 6 is engaged with the second tooth bar 9, the second tooth bars 9 that move up and down is connected with cylinder 10.In order to control scraper, rotate, on described gear-box 5, be hinged with rotary cylinder 11, the piston rod of rotary cylinder 11 and guide 2 are hinged and can promote guide 2 rotations.The first tooth bar 3 with the connected mode of guide 2 is: on described guide 2 inwalls, be fixed with on key 12, the first tooth bars 3 and offer vertically the keyway 13 matching with key 12.In order to prevent the extreme position of the first tooth bar 3, the upper end of described the first tooth bar 3 is provided with stop collar 14.When the first tooth bar 3 moves down always, stop collar 14 can be encountered the upper surface of guide 2 and hinder first tooth bar 3 limit and moves down.For the lower end that guarantees the first tooth bar 3 can be outside not exposed and being corroded property gas attack, described scraper 4 is fixed on the lower end of the first tooth bar 3 by axle sleeve 15, the lower end of guide 2 is arranged with sealing shroud 16, between axle sleeve 15 and sealing shroud 16, be connected with tetrafluoro cover 17, tetrafluoro cover 17 is enclosed within on the first tooth bar 3.Described cylinder 10 is fixed on gear-box 5, and on the second tooth bar 9, cover has guide cylinder 18, and the lower end of guide cylinder 18 is connected with the cylinder body of cylinder 10, and upper end is provided with positioning sleeve 19 and location-plate 20.
The course of work of the present utility model is: as shown in Figure 1 and Figure 2, when rotary drum is carried out to scraper, first utilizing cylinder 10 to drive on the second tooth bar 9 moves, the second tooth bar 9 drives driving gear 6 to rotate, driving gear 6 drives driven gear 7 to rotate by travelling gear 8, driven gear 7 drives the first tooth bar 3 to move down, and scraper 4 is just displaced downwardly to appropriate location thereupon.Because tetrafluoro cover 17 has retractility, therefore the lower end of the first tooth bar 3 all the time can be outside not exposed, corrosion that yet just can being corroded property gas.Then rotary cylinder 11 work, drag guide 2 and rotate, and guide 2 drives the first tooth bar 3 to rotate by key 12, thereby scraper 4 is attached on the material of drum inner wall, and rotary drum is carried out to scraper.In this process, do not use all the time lubricated wet goods liquid, with regard to not producing leakage, cause the situation of contaminated material yet.The utility model is simple in structure, easy to operate, quick.
