Full-automatic Buchner funnel-sand core funnel integrated intelligent suction filtration instrument

Abstract

The invention relates to a suction filtration instrument, specifically to a full-automatic Buchner funnel-sand core funnel intelligent suction filtration instrument. The full-automatic Brinell sand core two-in-one intelligent suction filtration instrument comprises a Buchner funnel, a sample holder A, a collection bottle, a panel, a suction filtration device, a filter membrane, a sand core, a sandcore funnel and a large-volume collection bottle, wherein a boss A, a suction filtration nozzle and a boss B are arranged on the suction filtration device; a relief hole, a hole A, a boss, a threadedhole A and a threaded hole B are formed in a tray; the relief hole is used for shunning the suction filtration nozzle on the suction filtration device; the hole A is sleeved with a sleeve; a spring is installed in the sleeve; the lower end of the spring makes contact with the boss A on the suction filtration device; and the upper end of the spring and the upper end of the sleeve make contact withthe bottom surface of a spring bearer plate. According to the intelligent suction filtration instrument provided by embodiments of the invention, full-automatic intelligent operation is realized in the whole assembly process of the instrument, monitoring is not needed, and the functions of active alarming and automatic stopping are achieved; multiple or more kinds of filtrates can be filtered atthe same time, remote operation can be achieved, and batch filtration of the filtrates can be realized.

Description

technical field [0001] The invention relates to a suction filter, in particular to a fully automatic Brinell sand core two-in-one intelligent suction filter. Background technique [0002] Suction filtration is also known as decompression filtration and vacuum filtration. It has double meanings. In physical terms, Leaching refers to the method of using an aspirator to reduce the pressure in the filtration bottle to achieve the purpose of solid-liquid separation. Suction filtration can be divided into Buchner funnel suction filtration and sand core suction filtration. Both Brinell suction filtration and sand core suction filtration have the following disadvantages: [0003] 1. Very cumbersome assembly process; 2. Manual operation; 3. In order to prevent the filtrate from being sucked back, professional supervision is required throughout the filtration process; 4. Multiple or multiple filtrates cannot be filtered at the same time.
