Description

Cover opening device of flat-open cover type centrifugal machine

Technical Field

The utility model relates to a flat-open lid formula centrifuge's device of uncapping.

Background

When the upper cover of the existing horizontal cover-opening type centrifuge is opened, the locking device of the upper cover is loosened, and then the upper cover is directly rotated to finish the opening operation. However, the cover opening mode enables the sealing ring on the bottom surface of the upper cover to repeatedly extrude and rub with the centrifuge shell, so that the sealing ring is extremely easy to damage. And the upper cover is easy to sink under the action of gravity, so that the situation that the flange surface of the upper cover collides with the shell or is even damaged often occurs during the cover closing operation.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the cover opening device of the flat-open cover type centrifuge enables the service life of the centrifuge to be longer.

For solving the technical problem, the utility model discloses the technical scheme who adopts does: the utility model provides a flat-open cover formula centrifuge's device of uncapping, including setting up the mount pad on the centrifuge base, detachably is equipped with the end cover on the mount pad, it is equipped with around vertical axle pivoted hand wheel to rotate on the end cover, the hand wheel middle part is equipped with vertical screw thread through-hole, wear to be equipped with the drive shaft in the screw thread through-hole, the drive shaft passes the end cover, the only commentaries on classics round pin that is equipped with the level setting in the end cover, be equipped with in the drive shaft and only changeing round pin complex vertical only commentaries on classics groove, the drive shaft rotates the cover on the part of wearing out the mount pad downwards and is equipped with the adapter sleeve, be equipped with the linking arm on the adapter sleeve, the linking arm is connected with the centrifuge upper cover.

As a preferred scheme, the outer side of the lower section of the hand wheel is provided with a limiting ring, and the end cover is provided with a gland which is matched with the limiting ring to limit the hand wheel to move up and down.

Preferably, the hand wheel is rotatably arranged on the end cover through an upper bearing.

Preferably, an upper wear-resistant sleeve is embedded in a portion, corresponding to the drive shaft, of the end cover, and the rotation stopping pin penetrates through the upper wear-resistant sleeve.

As a preferable scheme, a lower guide seat is arranged on the mounting seat, a vertical guide hole is formed in the lower guide seat, and the lower end of the driving shaft is movably embedded in the vertical guide hole.

As a preferable scheme, a lower wear-resistant sleeve matched with the driving shaft is arranged in the vertical guide hole.

As a preferable scheme, the connecting sleeve is sleeved on the driving shaft through an upper connecting bearing and a lower connecting bearing.

The utility model has the advantages that: when the centrifugal machine adopting the device is used for opening the cover, the driving shaft drives the upper cover of the centrifugal machine to ascend by 10-15mm by rotating the hand wheel, and then the upper cover of the centrifugal machine is manually rotated to finish the cover opening operation, so that the flange surface and the sealing element of the upper cover are protected, and the collision deformation of the flange surface and the damage of the sealing element after long-time use are avoided.

Because the outer side of the lower section of the hand wheel is provided with the limiting ring, and the end cover is provided with the gland which is matched with the limiting ring to limit the hand wheel to move up and down, the hand wheel is more reliably arranged.

Because the hand wheel is rotatably arranged on the end cover through the upper bearing, the hand wheel is more labor-saving to rotate.

Because the part of the end cover corresponding to the driving shaft is embedded with the upper wear-resistant sleeve, the rotation stopping pin penetrates through the upper wear-resistant sleeve, the upper wear-resistant sleeve can be made of more wear-resistant alloy steel, and the upper wear-resistant sleeve is easy to replace after being worn.

Because be equipped with down the guide holder on the mount pad, be equipped with vertical guiding hole in the lower guide holder, the lower extreme activity of drive shaft is inlayed and is established in vertical guiding hole for the motion of drive shaft is more stable.

Because be equipped with in the vertical guiding hole with drive shaft matched with lower wear-resisting cover, lower wear-resisting cover can adopt more wear-resisting alloy steel to make, and is easily changed after wearing and tearing.

Because the connecting sleeve is sleeved on the driving shaft through the upper connecting bearing and the lower connecting bearing, the upper cover of the centrifuge can be opened by rotating more labor-saving.
