Description

Technical Field

[0001] The invention specifically relates to the field of centrifuges, and in particular to a fully automatic paddle turning 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. It can also be used to remove liquid from wet solids, such as using a washing machine to spin dry wet clothes; special ultra-speed 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 particle sizes have different sedimentation speeds in liquids.

[0003] When the existing centrifuge performs centrifugal drying on the 3D printing base plate, it can only perform centrifugal drying on one side of the 3D printing base plate. When the other side is centrifuged, it needs to be reinstalled, the centrifugal efficiency is low, and after the centrifugation is completed, it needs to be baked subsequently, and the overall centrifugal and drying efficiency is low.

[0004] Therefore, we propose a fully automatic paddle turning centrifuge to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of low centrifugal drying efficiency of 3D printing base plates in the prior art by a centrifuge, and to propose a fully automatic paddle turning centrifuge.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, the rotating shaft is rotatably connected to the bottom of the drum via a bearing.

[0011] Preferably, a plurality of spoilers are provided at the bottom of the inner side wall of the shell, and the plurality of spoilers are distributed in a ring array.

[0012] Preferably, the spun-off liquid tray is arranged in a ring shape, and the inner side of the spun-off liquid tray is in contact with the outer side wall of the bottom of the drum.

[0014] Preferably, both sides of the paddle are provided with inclined surfaces inclined downward, and a splash guard is provided below the inclined surfaces.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting a paddle, when the 3D printed base plate is centrifuged, the 3D printed base plate is inserted between the two fork teeth and fixed, and then the motor is started, the motor drives the main shaft to rotate, and the main shaft drives the bottom of the drum to rotate. The bottom of the drum drives multiple 3D printed base plates to rotate through multiple rotating shafts and fork teeth. During the rotation, the paddle is deflected under the blocking effect of the damping fluid, and at the same time, the paddle drives the 3D printed base plate to rotate through the rotating shaft and fork teeth, so that one side of the 3D printed base plate faces the central axis of the shell, so that one side of the 3D printed base plate can be evenly centrifuged, and the 3D printed base plate can be evenly dried through the heater; when the motor shaft rotates in the opposite direction, the paddle is reversely deflected under the blocking effect of the damping fluid, so that the other side of the 3D printed base plate faces the central axis of the shell, so that the other side of the 3D printed base plate can be evenly centrifuged and dried, thereby improving the centrifugation and drying efficiency of the 3D printed base plate.

[0017] The present invention can evenly centrifuge and dry both sides of a 3D printing base plate, and has high centrifugation and drying efficiency for the 3D printing base plate. BRIEF DESCRIPTION OF THE DRAWINGS
