Embodiment Construction
[0017] Such as figure 1 As shown, a double-layer funnel with holes, the funnel is set as an outer funnel and an inner funnel, the inner funnel includes an inner funnel body 2 and an inner funnel tube 7, and the inner funnel has the same gap The round hole 1 of the inner layer funnel tube has a valve 5, and the outer layer funnel includes an outer layer funnel body 3 and an outer layer funnel tube 6, and the outer layer funnel body 3 communicates with the outer layer funnel tube 6, and the inner layer funnel 2 is nested in the outer funnel 3, the inner funnel 2 is separated from the outer funnel 3, and there is a small bracket 4 between them, forming a gap between the outer funnel tube 6 and the inner funnel tube 7 A drainage channel, the inner funnel tube extends from the bottom of the outer funnel tube.
[0018] Round holes 1 with a size of about 3 mm are evenly distributed on the inner funnel 2, and the round holes can speed up the outflow of liquid during filtration and im...

Abstract
The invention provides a double-layer funnel provided with holes and a device capable of efficiently separating slurry. The double-layer funnel provided with the holes comprises an inner-layer funneland an outer-layer funnel; the inner-layer funnel comprises an inner-layer funnel body provided with regularly arranged round holes and an inner-layer funnel tube provided with a valve; the outer-layer funnel comprises an outer-layer funnel body and an outer-layer funnel tube, the inner-layer funnel is nested in the outer-layer funnel, and a drain channel is formed between the inner-layer funnel and the outer-layer funnel. The device capable of efficiently separating slurry comprises a container for accommodating a liquid and the double-layer funnel and can perform variable-pressure operation,a gap funnel cover is arranged at one end of the outer-layer funnel body, the funnel body and the funnel cover are in frosted cooperation, edges are bulged, so that operation can be performed in a seal vacuum pumping mode and a pressurizing mode, vacuum pumping operation can be performed when the liquid is separated, the pressurizing operation can be performed when the slurry is separated, and the purpose of slurry separation can be achieved.
Description
technical field [0001] The invention relates to the technical field of a filter funnel and a device capable of separating slurry, in particular to the technical field of a filter funnel for experiment and analysis and suction filtration. Background technique [0002] At present, the filter funnel used for experiments and analysis uses round filter paper for filtration. During the filtration process, the filter paper is close to the wall of the funnel, and the filter residue is gradually deposited at the bottom of the funnel, which is prone to clogging and leads to low filtration efficiency. The ordinary funnel contains volatile substances in the separation solution, which will affect the health and safety of the experimental operators; when filtering easily oxidized compounds, it is easy to be oxidized and deteriorated by the oxygen in the air; when separating the slurry, it is easy to be blocked, resulting in failure to filter liquid, the filtration efficiency is low, and i...
