Embodiment 1

[0037] The filter beaker 1 suitable for stacking has a cup body 2, and the upper part of the cup body 2 has an upper channel 4 capable of installing a bevel body 3. The upper channel 4 is composed of two upper and lower cup body raised rings 6, 7. The cup body The raised rings 6 , 7 have openings, and the raised rings 6 , 7 of the cup body are located outside the cup body 2 . Inclined body 3 has funnel-shaped inclined-plane, and its upper opening diameter is greater than bottom opening diameter, has inclined-plane body convex ring 10 on the inner surface of inclined-plane body 3 lower opening sides, and inclined-plane body raised ring 10 has protrusion and opening, and inclined-plane body protrudes The ring 10 can cooperate with the channel 4, so that the inclined plane body 3 is installed on the top of the cup body 2 to form the beaker 1 for filtering. The relationship between the waist length H of the slope body 3 and the side length L of the funnel-shaped filter paper satis...

Embodiment 2

[0041] The filter beaker 1 suitable for stacking has a cup body 2, the upper and lower parts of the cup body respectively have an upper channel 4 and a lower channel 5 capable of installing a bevel body 3, and the upper channel 4 is protruded by two upper and lower cup bodies The rings 6, 7 are formed, the lower channel 5 is composed of two cup body raised rings 8, 9 up and down, the cup body raised rings 6, 7, 8, 9 have openings, the cup body raised rings 6, 7, 8, 9 is located outside the cup body. The slope body 3 has a funnel-shaped slope, and its upper opening diameter is greater than the bottom opening diameter, and the inner surface of the bottom opening side has a slope body protrusion ring 10, and the slope body protrusion ring 10 has a protrusion and an opening, which can have a groove and a groove. The channels 4 and 5 are used in conjunction with each other, and the inclined plane body 3 is installed on the upper and lower parts of the cup body 2 to form a filter be...

Embodiment 3

[0043] Such as figure 1 As shown, use the beaker in embodiment 1 as the first beaker, fold the first filter paper into a funnel shape and put it into the slope body 3 on the top of the first filter beaker 1, make the first filter paper and the slope body 3 close, To prevent the first filter paper from being damaged, pour the liquid to be filtered, and the liquid level of the liquid to be filtered is lower than the lowest position of the inclined plane body 3 .

[0044] The beaker in embodiment 2 is used as the second beaker, and the second filter uses the beaker 1 to be placed on the first filter paper of the first beaker, and the inclined plane body at the bottom of the second filter uses the beaker 1 to compress the first filter paper to prevent the first filter paper from Diffused during filtration. Fold the second filter paper into a funnel shape and put it into the beaker 3 on the upper part of the second filtering beaker 1, pour the liquid to be filtered, the liquid le...

Abstract

The invention provides a stacking placement type filtering beaker. A beaker body comprises channels and upper and lower cup body protruding rings, wherein the channels can be used for mounting obliqueplane bodies, and an opening is formed in the cup body protruding ring outside the cup body; oblique plane body protruding rings are arranged on the inner surfaces of opening sides of the lower partsof the funnel-shaped oblique plane bodies, comprise protruding parts and openings and can be mutually matched with the channels for use, and the oblique plane bodies are mounted at the upper and lower parts of the beaker body so as to form the stacking placement type filtering beaker. According to the stacking placement type filtering beaker, the deficiencies that an existing filtering beaker cannot be stacked in the filtering process and must be matched with a funnel for use so as to achieve a relatively good filtering effect are overcome.

Description

technical field [0001] The invention relates to a stacked filter beaker assembly, in particular to an assembly method of the stacked filter beaker assembly. Background technique [0002] In filtration experiments, filter paper is often used together with instruments such as filter funnels or Buchner funnels and beakers. Before use, the filter paper needs to be folded into a suitable shape. The common folding method is to fold the filter paper into a shape similar to a flower. The higher the degree of folding of the filter paper, the higher the surface area it can provide, and the better the filtering effect, but care should be taken not to overfold the filter paper and cause the filter paper to break. Put the draining glass rod on the multi-layer filter paper, and use even force to avoid damage to the filter paper. The specific operation process is as follows: [0003] 1. Fold the filter paper in half twice in a row to form a 90° central angle shape. [0004] 2. Open the...
