Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a high-speed centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions (e.g., separating cream from milk); they can also be used to remove liquids from wet solids, such as using a washing machine to spin dry wet clothes; special ultra-fast tubular separators can also separate gas mixtures of different densities; some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the fact that solid particles of different densities or sizes have different sedimentation speeds in liquids.

[0003] In the prior art, a threaded cover is generally provided in the centrifuge. However, since the threaded connection is troublesome, the cover needs to be tightened to ensure that it is firm and will not separate during high-speed rotation. At the same time, if it is too tight, it is difficult to open. Utility Model Content

[0026] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the structure of the centrifuge in some embodiments of the utility model; Figure 2 This is a structural connection diagram of the cover body and the centrifugal disk in some embodiments of the utility model.

[0028] The utility model provides a high-speed centrifuge, comprising a centrifuge body 1, the centrifuge body 1 comprising a shell 2, a centrifugal disc 4 arranged in the shell 2 and a cover body 5 used to cover the centrifugal disc 4, the outer wall of the centrifugal disc 4 is provided with a raised platform 41, the cover body 5 is covered on the raised platform 41, the bottom of the cover body 5 matches the top of the raised platform 41, the top of the raised platform 41 is provided with a plurality of first grooves 42, the first grooves 42 are each provided with a magnet block 43, the bottom of the cover body 5 is provided with a second groove 51 corresponding to the first groove 42, the second groove 51 is each provided with an iron column 52.

[0029] By placing the cover 5 on the centrifugal disk 4 and aligning the iron column 52 with the first groove 42 and inserting it, the magnet block 43 at the bottom adsorbs them together to connect the cover 5 with the centrifugal disk 4. This can avoid the cover 5 being separated due to the screw not being in place. When opening, you only need to use a certain amount of force to separate it, which is also convenient to open.

[0030] According to some embodiments of the utility model, optionally, an integral annular block 44 is provided on the outer wall of the centrifugal disc 4 just above the raised platform 41, and the outer wall of the annular block 44 is arc-shaped, and the cover body 5 is provided with a card slot 53 matching the annular block 44. When the cover body 5 covers the centrifugal disc 4, the annular block 44 is stuck in the card slot 53, and the bottom of the cover body 5 and the top of the raised platform 41 are matched to be sealed, and the surface of the annular block 44 is arc-shaped, which is conducive to separation or being stuck in the card slot 53, so that a connection insurance can be added to reduce the risk of damage caused by separation of the cover body 5 during the use of the centrifugal disc 4.

[0031] According to some embodiments of the utility model, optionally, a spring 55 is provided between the second groove 51 and the iron column 52. The spring 55 is provided between the iron column 52 and the second groove 51 so that when it is difficult to find the first groove 42, the cover body 5 is first covered on the centrifugal disk 4, so that the iron column 52 will be against the top of the raised platform 41, and then the iron column 52 will shrink under the action of the spring 55, and be aligned in the first groove 42 by rotation.

[0032] According to some embodiments of the utility model, the outer wall of the cover body 5 is optionally provided with a plurality of first positioning blocks 54, and the first positioning blocks 54 respectively correspond to the second grooves 51. In order to clearly see the position of the iron column 52 in the cover body 5, the position can be quickly aligned to connect with the centrifugal disc 4.

[0033] According to some embodiments of the utility model, optionally, the outer wall of the raised platform 41 is provided with a plurality of second positioning blocks 44, and the second positioning blocks 44 respectively correspond to the first grooves 42. In this way, during the rotation process after the cover body 5 is connected to the centrifugal disk 4, it can be well judged whether the connection is in place after the first positioning block 54 and the second positioning block 44 overlap.

[0034] According to some embodiments of the utility model, optionally, a cover plate 3 is provided on one side of the housing 2, and a shielding plate 31 is provided on the side opposite to the centrifugal disc 4. When the cover plate 3 is closed, there is a gap between the shielding plate 31 and the cover body 5. In this way, the shielding plate 31 can be placed above the cover body 5 after the cover body 5 is connected, and at the same time, it does not contact the cover body 5. If the cover body 5 moves upward, the cover body 5 can be prevented from flying out, and the cover body 5 can be adsorbed back under the action of the magnet block 43, so as to ensure the safety of the test.

[0035] According to some embodiments of the utility model, optionally, the shielding plate 31 is connected to the cover plate 3 through a connecting rod 32, and a glass panel 33 is provided around the connection, and the glass panel 33 is embedded in the cover plate 3. The internal situation can be observed through the glass panel 33, and if an abnormal sound is emitted from the centrifugal disc 4, the internal situation can be observed to shut down the machine, and the area of ​​the glass panel 33 is larger than the area of ​​the shielding plate 31, so as to avoid the shielding plate 31 blocking the internal situation from being seen clearly.
