Description

Technical Field

[0001] The utility model mainly relates to the technical field of centrifuges, in particular to a scraper mechanism of a centrifuge. Background Art

[0002] A centrifuge is a mechanical device that uses centrifugal force to separate the components of a mixture. It is mainly used to separate solid particles from liquid in a suspension, or to separate two immiscible liquids of different densities in an emulsion (such as separating cream from milk). In addition, it can also be used to remove liquid from wet solids, such as using a washing machine to spin dry wet clothes. Specially designed ultra-speed tubular separators can even separate gas mixtures of different densities. Centrifuges use the different sedimentation speeds of solid particles in liquids, and some centrifuges can also classify solid particles according to density or particle size.

[0003] When a centrifuge processes a high viscosity mixture, the liquid is thrown out of the bowl, while the solid is trapped by the filter. At high speeds, the centrifuge can effectively separate the materials. However, after repeated use, a large amount of material will accumulate on the inner wall of the centrifuge's bowl, so it needs to be cleaned regularly to avoid affecting the subsequent material processing effect.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] At present, the distance between the scraper and the drum of the centrifuge is mostly fixed. When the scraper is cleaning, if the scraper is too close to the drum, it is easy to cause damage to the drum. The gap from the drum will lead to incomplete cleaning. In addition, centrifuges of different diameters need to be installed with different scraper mechanisms for cleaning operations, resulting in poor adaptability of the scraper mechanism.

[0033] Refer to the attached Figure 1-5A scraper mechanism for a centrifuge comprises a mounting plate 1, wherein the mounting plate 1 is symmetrically provided with sliding grooves 2, wherein the sliding grooves 2 are matched and connected to a fixing mechanism 3, wherein the middle of the mounting plate 1 is rotatably connected to a rotating column 4, wherein the outer side of the rotating column 4 is connected to a driving device 5, wherein the bottom of the rotating column 4 is connected to a rotating column 6, wherein a cross lifting groove 7 is provided on the rotating column 6, wherein the middle of the cross lifting groove 7 is connected to a first rotating screw rod, wherein the cross lifting groove 7 is connected to a plurality of lifting cross plates 8 in a sliding manner, wherein the lifting cross plates 8 are matched and connected to a plurality of telescopic scrapers 9, and the device can be installed on different specifications When cleaning is needed, the mounting plate 1 is set on the top of the centrifuge. The fixing mechanism 3 can be fixed on the centrifuge after adjusting the spacing. Then the driving device 5 works to drive the rotating column 4 to rotate. During the rotation, the lifting cross plate 8 moves up and down in the cross lifting groove 7. The telescopic scraper 9 is connected to the side wall of the drum for scraping and cleaning. Before the telescopic scraper 9 works on the side of the drum, it can be replaced with a suitable length to ensure a better cleaning effect. The top of the first rotating screw is connected to the second motor, and the second motor reciprocates to drive the lifting cross plate 8 to lift and clean.

[0034] The fixing mechanism 3 includes a T-shaped slider 31, the bottom of the T-shaped slider 31 is connected to an arc-shaped clamping block 32, the T-shaped slider 31 is matched and connected to a second rotating screw 33, the end of the second rotating screw 33 is connected to a rotating disk 34, and the side of the rotating disk 34 is connected to a rotating handle 35. When the rotating handle 35 rotates, it will drive the T-shaped slider 31 to move in the slideway groove, thereby matching centrifuge drums of different diameters. The arc-shaped clamping block 32 at the bottom will clamp the edge of the centrifuge drum to play a positioning role.

[0035] The driving device 5 includes a first motor 51, which is arranged on the top of the mounting plate 1. The rotating shaft of the first motor 51 is connected to the first bevel gear 52, and the first bevel gear 52 is connected to the second bevel gear 53. The second bevel gear 53 is arranged on the outside of the rotating column 4. When the first motor 51 is working, it will drive the first bevel gear 52 to rotate, and then drive the rotating column 4 to rotate on the mounting plate 1.

[0036] The telescopic scraper 9 includes a connecting box 91, in which a second slide groove 92 is provided, and a plurality of springs 93 are connected to the inner wall of the second slide groove 92.

Plug holes 95 are provided at the four corners of the top of the connecting box 91, and the plug holes 95 match the connection limit cover 96. When the telescopic scraper 9 is used, it is necessary to select a T-shaped cleaning scraper block 94 of a suitable length according to the centrifuge drum before inserting it into the second slide groove 92. Before insertion, it is necessary to push the spring 93 into the lifting cross plate 8, and then insert the plug block at the bottom of the limit cover 96 into the corresponding plug hole 95 for limiting. When the T-shaped cleaning block is working, the spring 93 will push it outward, thereby achieving a good scraping effect.
