Abstract

The invention discloses a filtering separation device and a using method thereof. A liquid outlet in the bottom of a liquid container is in butt joint with a liquid inlet of an upper-layer Buchner funnel of a bidirectional suction flask through a pipeline, a liquid outlet in the bottom of the bidirectional suction flask is in butt joint with a liquid inlet of a lower-layer Buchner funnel through apipeline, and another liquid outlet in the bottom of the liquid container is in butt joint with another liquid inlet of the lower-layer Buchner funnel through a pipeline; an air inlet and an air outlet which are formed in the two-way suction flask and close to the bottleneck are respectively butted with the vacuum pump through pipelines; an air inlet and an air outlet which are formed in the one-way suction flask and close to the bottleneck are respectively butted with the vacuum pump through pipelines; and each pipeline is provided with a valve. Various passing operations including the first-level operation, the second-level operation, the third-level operation and the fourth-level operation are completed through cooperative use of all the valves on the device. The device is simple in structure, easy to disassemble and assemble, diverse in function and higher in efficiency.

Description

technical field [0001] The invention belongs to the field of chemical reaction devices, and in particular relates to a filtering and separating device and a using method thereof. Background technique [0002] The vacuum filtration device consisting of a vacuum pump, a single Buchner funnel and a single-mouth one-way suction filter flask is the most common filtration device in the laboratory, especially in the fields of material synthesis and catalyst preparation. However, with the continuous development of synthesis and preparation technology, people can obtain multiple samples of solid-liquid mixture at one time. The traditional vacuum filtration device can only filter one sample at a time, and the filtration efficiency is low, and it is impossible to achieve the same sample at the same time. Separation and washing of particles of different particle sizes in the sample. In addition, if the synthesis amount of the same sample is large, the filter cake will be relatively thi...
