Technical problem to be solved by this invention is: provide a kind of and can not produce the scraper in the centrifuge polluted to material.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the scraper in a kind of centrifuge, comprise casing, rotate and be provided with guide in casing, casing is stretched out in the upper end of guide, be provided with in guide and can endwisely slip and can radially not make the first tooth bar that cross section is circle in relative rotation along guide along guide, the lower end of the first tooth bar is stretched out guide and is provided with scraper, a radially side of described casing is provided with gear-box, at least be provided with two pitch wheels in gear-box, one of them gear and the engagement of the first tooth bar, also have a side of a gear to be engaged with the second tooth bar moved up and down, one end of the second tooth bar is connected with cylinder.
Be hinged with rotary cylinder on described gear-box, the piston rod of rotary cylinder and guide are hinged and can promote the guide rotation.
Be fixed with key on described guide inwall, offer vertically the keyway matched with key on the first tooth bar.
The upper end of described the first tooth bar is provided with stop collar.
Described scraper is fixed on the lower end of the first tooth bar by axle sleeve, the lower end of guide is arranged with sealing shroud, is connected with the tetrafluoro cover between axle sleeve and sealing shroud, and the tetrafluoro cover is enclosed within on the first tooth bar.
Described cylinder is fixed on gear-box, and on the second tooth bar, cover has guide cylinder, and an end of guide cylinder is connected with the cylinder body of cylinder, and the other end is provided with positioning sleeve and location-plate.
The invention has the beneficial effects as follows: whole device does not all have to adopt lubricated wet goods liquid, and the situation that also just can not produce the liquid contamination material occurs.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the invention scheme in detail.
As shown in Figure 1 and Figure 2, scraper in centrifuge of the present invention, 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, be provided with in guide 2 and can endwisely slip and can radially not do cross section in relative rotation along guide 2 and stretch out guide 2 and be provided with scraper 4, the first tooth bar 3 upper ends for the lower end of the first tooth bar 3, the first tooth bars 3 of circle and be arranged with case 21 along guide 2.A radially side of described casing 1 is provided with gear-box 5, at least be provided with two pitch wheels in gear-box 5---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.Rotate in order to control scraper, 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: be fixed with on described guide 2 inwalls on key 12, the first tooth bars 3 and offer vertically the keyway 13 matched 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, be connected with tetrafluoro cover 17 between axle sleeve 15 and sealing shroud 16, 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 invention 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 and rotates, driving gear 6 drives driven gear 7 by travelling gear 8 and rotates, driven gear 7 drives the first tooth bar 3 and moves down, and scraper 4 just is 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 by key 12 and rotates, thereby makes scraper 4 be attached on the material of drum inner wall, and rotary drum is carried out to scraper.All the time do not use lubricated wet goods liquid in this process, with regard to not producing leakage, cause the situation of contaminated material yet.The present invention is simple in structure, easy to operate, quick.
