Detailed Description

The embodiment provides a technical scheme:

as shown in fig. 1-2, a small reactor with a filtering function comprises a hollow upper accommodating tube 3, a hollow lower accommodating tube 1 and a filtering device, wherein the upper accommodating tube 3 is detachably connected with the lower accommodating tube 1, the filtering device comprises a columnar mounting frame 2 and a filtering net 22, the filtering net 22 is fixedly arranged in the columnar mounting frame 2, a first fixing groove adapted to accommodate the columnar mounting frame 2 is formed in the inner side of the opening end of the lower accommodating tube 1, a second fixing groove adapted to accommodate the columnar mounting frame 2 is formed in the inner side of the upper accommodating tube 3, and the upper end and the lower end of the columnar mounting frame 2 are respectively contacted with the groove bottoms of the second fixing groove and the first fixing groove; the fixed strip 24 that is equipped with in upper end of column mounting bracket 2, the both sides of fixed strip 24 all articulate and are equipped with baffle 25. The inside of the upper containing pipe 3 is also provided with a jack 5 for pushing down the shutter 25.

In this embodiment, the upper and lower

accommodating tubes

3 and 1 are detachably connected. When the experimenter needs to use this reactor to carry out centrifugal operation, can put into first fixed slot with the lower extreme of column mounting bracket 2, then through holding pipe 3 and holding pipe 1 down fixedly being connected. At this time, the upper end of the column-shaped mounting bracket 2 is inserted into the second fixing groove to be fixed.

When the reactor is used, two experimental steps are respectively and correspondingly realized, the first step is to extract a target object in a sample, and the second step is to filter a mixture after the extraction reaction is reversed while centrifuging, so that an experimenter does not need to further filter (filter) a clear solution obtained after centrifuging at the later stage. When carrying out first step, the experimenter can be with the baffle 25 of column mounting bracket 2 upper end position in fixed strip 24 both sides upwards turn up for baffle 25 is in the vertically state with the inside wall of column mounting bracket 2, and the experimenter can pour solid sample and extraction reagent into and hold in the pipe 3 on. And the solid-liquid mixture is stirred by the ejector rod 5, so that the target substance in the solid sample is precipitated. After extraction is finished, the baffle 25 can be pushed down through the ejector rod 5, so that the baffle is turned over, and the solid-liquid mixture in the upper accommodating pipe 3 flows into the upper part of the filter screen. At this moment, the laboratory technician can carry out centrifugal operation, waits that the centrifugation finishes the back, can dismantle holding pipe 3 on, take off the clear liquid in holding pipe 1 can.

In this embodiment, the tank bottom of first fixed slot is equipped with first arc recess, and correspondingly, the lower extreme of column mounting bracket 2 is equipped with the first arc sliding part with first arc recess adaptation, and the tank bottom of second fixed slot is equipped with second arc recess, and correspondingly, the upper end of column mounting bracket 2 is equipped with the second arc sliding part with second arc recess adaptation.
