Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical intermediate processing, in particular to a filtering device for pharmaceutical intermediates. 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 an ordinary chemical plant. As long as it reaches a certain level, it can be used for drug synthesis. At present, in the process of processing pharmaceutical intermediates, it is necessary to filter the impurities inside them.

[0003] The Chinese patent with the announcement number CN218589905U discloses a filtering device for pharmaceutical intermediates, which specifically relates to the technical field of filtering devices. The utility model includes a sealing shell, a sealing cover is provided at the upper end of the sealing shell, a sealing bottom is provided at the lower end of the sealing shell, a liquid inlet is provided on the surface of the sealing cover, an exhaust port is provided on the surface of the sealing cover, a liquid outlet is provided on the surface of the sealing bottom, an air outlet is provided on one side of the sealing shell, a sealing device is provided inside the sealing shell, the sealing device includes a top plate, and a plurality of placement grooves are provided at one end of the top plate close to the sealing cover. The utility model fills the top plate and the inside of the sealing shell by adding a rubber ring on the top plate. The gap between the partition layers makes the top plate and the partition layer contact more closely, preventing the gas between the top plate and the cover from entering the space between the ultrafiltration backwash water filter element and the partition layer, affecting the gas discharge efficiency of the space between the ultrafiltration backwash water filter element and the partition layer through the outlet pipe. However, in the above patent, during the filtering process of the pharmaceutical intermediates, the filtering mechanism is easily tilted by the impact of the pharmaceutical intermediates during transportation, and the impurities inside are accumulated, which has a certain impact on the filtering speed of the pharmaceutical intermediates of the device and reduces the working efficiency of the device. For this reason, we propose a filtering device for pharmaceutical intermediates to solve the above problems. Utility Model Content
