Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing, in particular to a pharmaceutical intermediate pulverizing device. Background Art

[0002] The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a drug production license and can be produced in ordinary chemical plants. As long as it reaches a certain level, it can be used in the synthesis of drugs.

[0003] Chinese utility model patent CN220803499U discloses a pharmaceutical intermediate grinding device, including a box body, wherein two supporting feet are arranged on the left and right sides of the bottom of the box body. The pharmaceutical intermediate grinding device starts a second driving motor to drive the rotating shaft and two driving bevel gears to rotate, and then drives two second mounting shafts and two crushing rollers to rotate in the opposite direction through two driven bevel gears, so as to crush the raw materials falling from the feed hopper, thereby avoiding the subsequent grinding being affected by the raw materials sticking together, and secondly, starts two vacuum pumps to extract the air in the two collection boxes, so that the air containing dust in the box body enters the inside of the two collection boxes through two air inlet pipes respectively, and filters the dust in the air through two filter screens, so as to perform dust removal operation in the box body, and avoid pollution to the environment caused by dust diffusion.

[0004] In order to perform dust removal operations inside the box, the above-mentioned device is installed with structures such as a vacuum pump, a collection box and a filter net.
