Description

technical field [0001] The invention relates to the field of washing and filtering of medicine and fine chemical industry, in particular to a washing and filtering device. Background technique [0002] In the process of pharmaceutical and fine chemical production, solid materials often need to be washed and filtered repeatedly. In the traditional unit operation, washing and filtering are completed by two independent equipments, and the materials need to be transferred between the equipments, which increases the complexity of the operation, and at the same time, material loss and pollution are unavoidable during the transfer process. Contents of the invention [0003] In order to solve the above problems, the present invention provides a washing and filtering device capable of completing the two processes of washing and filtering, which can avoid contamination and loss during material transfer. [0004] A washing and filtering device in the present invention comprises a ta...
