Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical intermediate production technology, specifically to a grinding device for pharmaceutical intermediates. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they reach a certain level, they can be used in drug synthesis.

[0003] In the production of pharmaceutical intermediates, grinding equipment is often used to grind them. However, ordinary grinding equipment is prone to material splashing during grinding, resulting in material loss. Furthermore, collecting the material after grinding is quite troublesome. Therefore, a grinding device for pharmaceutical intermediates is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for pharmaceutical intermediates to overcome the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, this utility model provides a grinding device for pharmaceutical intermediates, comprising a base, a grinding tank, and a support plate. The base has a slide rail, the bottom of the grinding tank has a sliding plate, and the bottom of the sliding plate has a slider that can slide within the slide rail. Both the slider and the slide rail have I-shaped cross-sections. The base is connected to the bottom surface of the support plate via four support columns. The bottom surface of the support plate is connected to the top surface of a lifting plate via a cylinder. The top surface of the lifting plate has a drive motor, whose output shaft passes downward through the lifting plate and is fixedly connected to a grinding body located below the lifting plate. The grinding body is hemispherical. The side wall of the grinding tank has an annular folded edge with a limiting hole. A circular plate is provided between the lifting plate and the grinding body, with a through channel on the circular plate containing a bearing for use with the output shaft. The bottom surface of the circular plate has a limiting rod for use with the limiting hole. The top surface of the grinding tank has an annular groove, and the bottom surface of the circular plate has an annular plate that can be inserted into the annular groove.

[0006] Preferably, the number of cylinders is at least two.

[0007] Preferably, the number of the limiting rod and the limiting hole is at least two.

[0008] Preferably, the grinding groove is provided with a handle.

[0009] Preferably, the base is provided with a limiting groove, the sliding plate is provided with a through hole, and a limiting post is provided in the through hole.

[0010] The beneficial effects of this utility model are as follows: The grinding tank is installed on the base by a slider and slide rail, and the grinding tank is moved to directly below the grinding body. The limiting post is inserted into the through hole and the limiting groove to fix the grinding tank. The material to be ground is put into the grinding tank, and the cylinder drives the lifting plate to descend, so that the grinding body enters the grinding tank and the annular plate enters the annular groove. The limiting rod is inserted into the limiting hole. The drive motor runs and drives the grinding body to rotate, grinding the material in the grinding tank. The annular plate enters the annular groove, which can block the opening on the top surface of the grinding tank to prevent the material from splashing during the grinding process. The limiting rod can fix the annular plate to prevent the annular plate from rotating with the bearing. Similarly, the limiting rod can ensure the relative position between the grinding body and the grinding tank to ensure the grinding effect. The cylinder drives the drive motor to move up and down back and forth, which can increase the grinding effect. After the grinding is completed, the cylinder drives the drive motor to return to its original position, the limiting post is pulled out, and the grinding tank can be taken out by the handle to collect the material, which is very convenient.
