Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal processing, in particular to a centrifugal device for preparing pharmaceutical intermediates. Background Art

[0002] At present, centrifugation is a technology that rotates the solution around the axis at high speed, using centrifugal force to precipitate some components and leave some components in the supernatant. The circular motion of the object generates centrifugal force. At the same speed, due to the different densities and masses of the components, the particles move along the tangent due to the action of centrifugal force, thereby achieving the effect of separation between different components.

[0003] In order to ensure the stability of the centrifugal device on the market, the filter screen and the rotating barrel are connected in an integrated manner. However, this traditional centrifugal processing method is inefficient and requires a lot of time to wait for the material to be centrifugally screened by the filter barrel. Therefore, a new technical solution needs to be designed to solve the problem. The efficiency of centrifugal screening can be improved by external force. Utility Model Content

[0004] The utility model aims to provide a centrifugal device for preparing pharmaceutical intermediates, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a centrifugal device for preparing pharmaceutical intermediates, comprising a centrifugal tank, wherein both sides of the centrifugal tank are fixedly installed with limit slideways, two groups of limit slideways are slidably installed with limit slip rings, and the two groups of limit slip rings are fixedly installed with inner screening cylinders, and an extrusion mechanism is installed in the inner screening cylinder;

[0006] The extrusion mechanism includes a material guide cylinder connected to the bottom of the inner screening cylinder, a protective cover movably installed on the top of the centrifugal tank, a piston hole opened in the middle of the protective cover, a piston rod movably installed in the piston hole, and an extrusion block fixedly installed at the bottom of the piston rod, and the extrusion block corresponds to the inner wall of the inner screening cylinder.

[0007] As an optional solution of the technical solution of the present application, a spring is sleeved on the outer wall of the piston rod, and the two sides of the spring are respectively fixed to the protective cover and the outer wall of the piston rod, so as to support the piston rod.

[0008] As an optional solution of the technical solution of the present application, a discharge port is provided on one side of the bottom of the centrifuge tank, and a mesh grill is fixedly installed on the top of the guide cylinder to discharge moisture and materials.

[0009] As an optional solution of the technical solution of the present application, a rotation groove is opened on the outer wall of the extrusion block, and a sealing ring is rotatably installed in the rotation groove to support the inner screening cylinder.

[0010] As an optional solution of the technical solution of the present application, a gear ring is fixedly installed at the bottom of the inner screening drum, and a gear is meshingly installed on the gear ring to drive the inner screening drum to rotate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The technical solution of the present application drives the gear to rotate through a driving motor, and the gear ring meshing with the gear will drive the inner screening cylinder of the gear to rotate, thereby centrifugally screening the objects inside the inner screening cylinder. At the same time, the piston rod in the downward pressing extrusion mechanism pushes the extrusion block at the bottom and continuously approaches the bottom of the inner screening cylinder, which not only squeezes out the moisture contained in the material and further efficiently discharges the moisture by centrifugation, but also can squeeze out the dry material from the guide cylinder to improve the efficiency of material discharge after centrifugation.

[0014] 2. The technical solution of the present application is to open a rotating groove on the outer wall of the extrusion block, and a sealing ring is rotatably installed in the rotating groove. When the operator presses down the extrusion block at the bottom of the piston rod, the sealing ring rotatably installed on the outside of the extrusion block can not only block the material from being discharged from the top of the extrusion block, but also support the extrusion block to avoid friction between the rotating inner screening cylinder and the extrusion block and cause damage.
