Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film cleaning technology, specifically to a solid-liquid separation standard storage bottle. Background Technology
[0002] Before use, melamine standards need to be mixed with methanol-water solvent. Generally, melamine standards and methanol-water solvent need to be stored separately. This is because melamine is weakly alkaline, while methanol, as a polar solvent, may form a weakly acidic environment due to moisture absorption. Mixing the two may trigger an acid-base neutralization reaction, leading to the decomposition of melamine or oxidation of methanol, which will affect the purity of the standard.
[0003] However, storing melamine standard and methanol-water separately is not convenient for use, as it requires mixing the melamine standard and methanol-water solvent separately before use, which reduces the convenience of use.
[0004] Therefore, a solid-liquid separation standard storage bottle is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a solid-liquid separation standard storage bottle to solve the problem mentioned in the background art that existing melamine standards and methanol aqueous solvents are stored separately, requiring mixing before use, which reduces the convenience of use.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A solid-liquid separation standard storage bottle includes a liquid chamber with a twisted neck at the upper end and a drain protrusion at the lower end of the liquid chamber. A rubber stopper is also provided on the inner side of the drain protrusion. A solid chamber is correspondingly provided below the liquid chamber, and a hollow groove is formed at the upper end of the solid chamber. The lower end of the solid chamber is an open structure. The top end of a pull rod extends into the lower opening of the solid chamber, and three piston retaining rings are provided on the inner side of the solid chamber.
[0008] Preferably, the piston retaining ring is an elastic structure used to define the position of the top end of the pull rod.
[0009] Preferably, the top of the pull rod has a rubber piston head for seamless sliding connection with the inner side of the lower opening of the solid cavity, and the middle rod of the pull rod has a cross-shaped cross section and the bottom end has a 50mm diameter disc structure, which facilitates the vertical extraction of liquid from the solid cavity after solid-liquid mixing.
[0010] Preferably, the natural diameter of the rubber plug inside the drainage protrusion is larger than the inner diameter of the drainage protrusion, ensuring that the rubber plug stably blocks the drainage protrusion.
[0011] Preferably, the outer side of the drainage protrusion and the inner side of the hollow groove are threaded together.
[0012] Preferably, a plug is threaded into the hollow groove at the upper end of the solid cavity.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the solid-liquid separation standard storage bottle can simultaneously store the melamine standard and methanol aqueous solution after mixing. When using it, there is no need to mix it again, and it can help the two mix quickly, thereby improving the convenience of use. In addition, it can also help with refrigeration after use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 The present invention provides the following technical solution:
[0023] A solid-liquid separation standard storage bottle includes a liquid chamber 1 with a twisted neck at the upper end and a drain protrusion 5 at the lower end. A rubber stopper is provided inside the drain protrusion 5. A solid chamber 2 is correspondingly located below the liquid chamber 1, and a hollow groove 6 is formed at the upper end of the solid chamber 2. The liquid chamber 1 is connected to the solid chamber 2 via a detachable connection between the drain protrusion 5 and the hollow groove 6. The lower end of the solid chamber 2 is open. Matching threads are provided on the outer side of the drain protrusion 5 and the inner side of the hollow groove 6 for detachable connection. The rubber stopper inside the drain protrusion 5 has a diameter larger than its inner diameter to ensure stable blockage. The top end of a pull rod 3 extends into the lower opening of the solid chamber 2, and three piston retaining rings 4 are provided inside the solid chamber 2. The piston retaining rings 4 are elastic structures used to limit the position of the top end of the pull rod 3. The end has a rubber piston head for seamless sliding connection with the inner side of the lower opening of the solid chamber 2. The middle rod of the pull rod 3 has a cross-shaped cross section and a 50mm diameter disc structure at the bottom, which facilitates the vertical extraction of liquid from the solid chamber 2 after solid-liquid mixing. In use, twist off the twist neck at the upper end of the liquid chamber 1, and then pull down the pull rod 3 to press the rubber stopper in the drain protrusion 5 into the solid chamber 2. At this time, the methanol-water solution in the liquid chamber 1 can flow into the solid chamber 2. Then, by disassembling and removing the drain protrusion 5, the liquid chamber 1 and the solid chamber 2 are separated. Then, select the stopcock 7 that matches the hollow groove 6 and rotate and fix the stopcock 7 in the hollow groove 6 to make the solid chamber 2 a sealed space. Finally, shake the solid chamber 2 by hand to ensure that the melamine standard and the methanol-water solvent are fully mixed. Then remove the stopcock 7, and the mixed standard solution can be used. Any unused standard solution can be refrigerated and used later after screwing on the stopcock 7.
