Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and more specifically to a distributed suction filtration funnel feeding device and a suction filtration device. Background Art

[0002] The suction funnel is a commonly used filtration device in laboratories, usually used for the physical separation of mixtures of solid and liquid substances.

[0003] However, when using the existing filtration funnel, the filter paper is first laid, and then the sample to be filtered is directly poured into the filtration funnel. This pouring method is prone to cause the surface of the filtration solid above the filter paper to be uneven after the sample is poured in. Because the pouring pressure is too high, it is easy to produce depressions at the pouring site, or the filter cake may crack, resulting in poor filtration effect.

[0004] Therefore, providing a distributed filtration funnel feeding device and a filtration device that improves the filtration effect is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a decentralized suction filtration funnel feeding device and a suction filtration device, which are simple and convenient to operate, efficient and quick, and can flush evenly and fully, thereby improving the filtering and washing effects.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A distributed suction filtration funnel feeding device comprises a cylinder and a guide plate, wherein the cylinder is vertically connected; the guide plate is horizontally installed inside the cylinder, and the guide plate is provided with a plurality of distributed holes.

[0008] By adopting the above scheme, the beneficial effects of the utility model are:

[0009] The guide plate can prevent the flatness of the surface of the material to be filtered from being damaged due to the concentration of water flow when the flushing liquid is poured in, and the flushing is uniform and sufficient, thereby improving the washing effect.

[0010] Furthermore, it also includes a lifting rod, which is arranged on the guide plate.

[0011] Furthermore, the height of the lifting rod along the lifting direction is greater than the radial height of the guide plate from the edge of the cylinder.

[0012] The beneficial effect of adopting the above further technical solution is that it is easy to take out and place the feeding barrel part.

[0013] Furthermore, the dispersed holes have uniform pore sizes and are dispersed evenly.

[0014] Furthermore, the diameter of the dispersed holes is 1-3 mm.

[0015] A suction filtration device comprises a filter bottle and a suction filtration funnel, and also comprises a dispersed suction filtration funnel feeding device as described above, which is arranged inside the suction filtration funnel. BRIEF DESCRIPTION OF THE DRAWINGS
