Solvent filter with incense-coiled flow passes

Abstract

A solvent filter with incense-coiled flow passes replacing a solvent filter device is formed by a wheel disc body upper cover as well as a wheel disc body lower disc and a filtering diaphragm, and is characterized in that under the action of negative pressure or positive pressure, fluid medium is filtered along the overflowing systems of incense-coiled flow passes during movement, at the moment, the fluid medium is respectively injected into the tubular column bodies of the wheel disc body upper cover as well as the wheel disc body lower disc by virtue of medical injectors with large capacity, the column body of the wheel disc body upper is fully injected with fluid medium through the medical injector, and the injector on the wheel disc body lower disc is a cavity and is used for enabling the overflowing systems of the solvent filter with the incense-coiled flow passes generate negative pressure when the handle of the injector is pulled; the fluid medium moves along the incense-coiled flow, passes under the action of pressure difference and passes through the filtering diaphragm during movement; under the action of negative pressure or positive pressure, and the purpose is achieved that the fluid medium is filtered while flowing during to-and-fro flowing on a plane; and the solvent filter with the incense-coiled flow passes is proved to be a novel solvent filter which has the advantages of small size, no pollution, convenience in use, no electrical energy, high filtration precision and no residual medium.

Description

1. Technical field: [0001] The patent of the invention belongs to the field of scientific and technological experimental equipment, and in particular relates to a purification medium device for fluid detection analysis, quality inspection and the like. 2. Background technology: [0002] Necessary experimental equipment for microscopic analysis of a certain substance in the laboratory, solvent filter device: it includes filter membranes of different types and pore sizes, oil-free vacuum pumps, triangular liquid collection bottles, sand core filter plates, filter cups, Fixing clips, etc., have higher requirements on the quality of various equipment to achieve the purpose of clarifying and filtering to remove impurities. The device is cumbersome in use, has high requirements for device system hygiene, and the process efficiency is low, especially when it involves food, medicine, etc. Microcosmic analysis shows its deficiencies and shortcomings. 3. Contents of the invention: ...
