Magnetic separator and cleaning method

Abstract

The invention provides a magnetic separator and a cleaning method, and belongs to the technical field of pharmacy, and the magnetic separator comprises a main frame body, a magnetic suction assembly, a connecting assembly, a magnetic suction isolation sleeve and a first flexible isolation sleeve. A mounting sleeve is arranged at the lower end of the main frame; the magnetic attraction assembly comprises a bottom plate arranged below the main frame body and a magnet rod installed on the upper end face of the bottom plate. The magnetic isolation sleeve is mounted on the upper end surface of the bottom plate; the mounting sleeve is sleeved with the upper end of the first flexible isolation sleeve, and the magnetic attraction isolation sleeve is sleeved with the lower end of the first flexible isolation sleeve. According to the magnetic separator, the magnet rod and medicine materials are isolated by the magnetic isolation sleeve, it can be ensured that the magnet rod is always kept in a clean state, the situation that the magnet rod is rapidly demagnetized due to frequent cleaning is avoided, the service life of the magnet rod is prolonged, and in addition, by means of the cleaning method, the cleaning efficiency is improved. The material leakage can be prevented in the process of disassembling and assembling the magnet rod, and particularly in the production process of toxic and harmful materials, the operation environment and operators can be effectively protected.

Description

technical field [0001] The invention belongs to the technical field of pharmacy, and more particularly, relates to a magnetic separator and a cleaning method. Background technique [0002] In the pharmaceutical manufacturing process, since most of the production equipment used has knives and screens, and the knives and screens are worn out, the worn metal powder eventually enters the drug, which ultimately affects the metal impurity content of the drug. The requirements for the content of metal impurities in medicines are becoming more and more stringent, and magnetic separators are required to remove metal impurities after the medicines are crushed. [0003] Some drugs have the characteristics of high toxicity and high activity. According to the national GMP requirements, operators must be protected during the whole production process of such drugs to prevent leakage during the whole process of drug production and cause harm to operators. Magnetic separators are often unab...

Problems solved by technology

[0003] Some drugs have the characteristics of high toxicity and high activity. According to the requirements of national GMP, the operators must be protected during the whole process of the production of such drugs to prevent leakage during the whole process of drug production and cause harm to the operators. However, the existing Magnetic separators are often unable to protect operators during use and cleaning; in the production process of pharmaceuticals with high production costs and strict requirements on impurities, it is necessary to frequently test the quality of pharmaceuticals. The iron removal rods of existing magnetic separators are made of permanent magnets. , frequent cleaning will lead to degaussing of the magnet bar
