Description

Technical Field

[0001] The utility model belongs to the technical field of storage racks, and particularly relates to a core funnel storage rack. Background Art

[0002] A core funnel is an acid-resistant glass filtering instrument, which is composed of excellent hard high-borosilicate glass, has high physical and chemical properties, integrates the two functions of extraction and filtration, and is often used to extract and separate target substances in samples, and is applicable to chemical analysis, hygiene inspection, petroleum industry, pharmaceutical industry, dye industry, etc. The core funnel is divided into two upper and lower parts, with an upper feeding port at the top and a lower discharging port at the bottom. When in use, it is necessary to ensure that there is a certain operating space above and below. In addition, when drying, due to the special shape of the glass core funnel, it needs to be placed obliquely, there is a risk of sliding, and when weighing, placing it sideways will cause the sample to fall off, resulting in too large an error in the weighing data and low test accuracy. Therefore, a bracket is also needed to help fix the core funnel for convenient experimental operation and drying process.

[0003] Currently, generally, the core funnel is clamped on an iron stand for experimental operation. However, since it is necessary to clean, add samples or change extraction solvents to the core funnel between each extraction, it is necessary to repeatedly pick and clamp the core funnel during the operation process, which is very likely to cause unstable clamping, thus affecting the smooth progress of the experimental operation. In addition, when multiple core funnels need to be used simultaneously for batch operation, a large number of iron stands are required, occupying a large amount of experimental instruments and experimental benches, and it is not convenient for operation.

[0004] Chinese Patent CN203678064U discloses a core funnel rack, which includes a bracket and a tray placed under the bracket. A horizontally arranged first support plate and a second support plate are installed on the bracket. A first placement hole is arranged on the first support plate, and a second placement hole is arranged on the second support plate. The diameter of the first placement hole is greater than or equal to the maximum horizontal length of the core funnel, suitable for the core funnel to be inserted vertically; the diameter of the second placement hole is smaller than the plug length of the core funnel and at the same time greater than the maximum horizontal length of the part of the core funnel below the plug; the minimum distance from the center of each second placement hole to the outer edge of the second support plate is smaller than the distance from the operating end of the plug to the central axis of the core funnel. It can conveniently place the core funnel in the first placement hole, and the piston of the core funnel can also be conveniently opened and closed. The tray as the base can automatically drain the waste liquid, thus facilitating the storage of the core funnel and experimental operation.

[0005] However, in the existing core funnel racks, the placement positions of the core funnels are fixed, the spacing is not adjustable, and at the same time, the placement positions of the core funnels are few, which cannot meet large-scale experiments. Therefore, it is necessary to design a core funnel storage rack that can independently adjust the placement positions of the core funnels and is suitable for large-scale experiments.
