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 device that separates solids and liquids through the action of centrifugal force. The object to be separated is placed in a centrifugal bucket, and then the centrifugal bucket is rotated to generate centrifugal force, so that the liquid in the object is thrown out through the bucket, while the solid in the object will be limited by the bucket and remain in the bucket, thereby achieving solid-liquid separation.

[0003] In order to improve the separation efficiency in the prior art, the rotation speed of the centrifugal barrel is increased to complete the solid-liquid separation faster. However, as the centrifugal barrel rotates at a high speed, the centrifugal barrel will move in opposite directions, resulting in abnormal noise and greater friction during the rotation of the centrifugal barrel, thereby reducing the stability of the centrifugal mechanism.

[0004] Therefore, it is particularly important to design a new type of high-speed centrifuge to solve the above-mentioned technical defects and improve the practicality of the overall high-speed centrifuge. Utility Model Content

[0010] As a preferred solution of the utility model, the coupling is connected to the driving motor through a synchronous belt, and the connecting shaft in the coupling passes through the centrifuge housing and extends to the position of the centrifuge barrel.

[0012] As a preferred solution of the utility model, the sealing cover is fixedly connected to a limiting seat inside the centrifuge housing and at a position corresponding to the limiting ring, roller grooves are provided inside the two groups of limiting seats, and a plurality of rolling wheels are rotatably connected inside the two groups of roller grooves.

[0013] As a preferred solution of the utility model, the connecting assembly includes a connecting ring, a positioning member and a limit cover. The connecting ring is fixedly connected to the back of the centrifugal barrel and is located at a position corresponding to the coupling connecting shaft. The connecting ring and the coupling connecting shaft are connected by two sets of positioning members.

[0014] As a preferred solution of the utility model, the two groups of positioning members both pass through the connecting ring and the coupling connecting shaft and are respectively connected to two groups of limit covers. The two groups of positioning members are designed in a cross-shaped cross structure, and the connection method between the two groups of positioning members and the two groups of limit covers is threaded connection.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the utility model, through the design of the centrifuge housing, the centrifugal bucket and the connecting assembly, the connecting assembly is convenient for limiting and fixing the connecting shaft of the centrifugal bucket and the coupling, so as to facilitate the driving assembly to drive the centrifugal bucket to rotate.
