Description

Technical Field

[0001] The utility model relates to the technical field of chemical test vessels, in particular to an inverted conical bottle cap dedicated to the inspection of ferrous iron. Background Technique

[0002] A conical flask is called a conical flask because of its large belly and small mouth, similar to a cone, and it is a container often used in chemical detection. When detecting ferrous iron in a sample, a conical flask is usually used as a container for sample dissolution and titration. To avoid the oxidation of ferrous iron in the sample and cause the test result to exceed the standard, during the heating and sample dissolution process, a crucible lid of appropriate size is usually used to cover the bottle mouth in the reverse direction to prevent external air from entering the conical flask and oxidizing ferrous iron. At the same time, the liquid splashed on the bottle lid during the heating and sample dissolution process due to the boiling of the sample flows back into the bottle along the small handle on the lid. At the end of the sample dissolution, the bottle lid needs to be rinsed to ensure accurate results.

[0003] To avoid the phenomenon that the test result exceeds the standard, the titration detection of ferrous iron requires "hot titration and fast titration" (after the liquid in the conical flask boils to the required time, without waiting for it to cool to room temperature, the corresponding reagent is added for titration). However, the crucible lid is not a dedicated bottle lid and is not conducive to rinsing, which will affect the test result. At the same time, there is sample dissolution splashing liquid on the small handle, so that the tester can only hold the edge of the bottle lid for rinsing. Due to "hot titration and fast titration", the operator can only wear wire gloves to prevent burns to ensure flexible operation. As a result, the strong acid-containing rinsing liquid often splashes onto the hands, causing harm to the test personnel. Therefore, we propose an inverted conical bottle cap dedicated to the inspection of ferrous iron to solve the above problems. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] As Figures 1-3As shown in the figure, a special inverted conical bottle cap for testing ferrous iron proposed in an embodiment of the present utility model includes a bottle body 1. The top of the bottle body 1 is in movable contact with a bottle cap main body 2. The bottom of the bottle cap main body 2 is fixedly connected to a bottle cap bottom 3. A hollow bottle bottom 4 is provided on the bottle cap bottom 3. Two handles 5 are embedded at the top of the bottle cap main body 2. An edge portion 7 is provided at the bottom of the bottle cap main body 2. The edge portion 7 fits with the top of the bottle body 1. The design of the inverted conical bottle cap bottom 3 replaces the traditional inverted pointed small handle, enabling the liquid in the bottle body 1 to condense after boiling and the liquid splashed onto the cap to better flow back into the bottle body 1. The design of the hollow bottle bottom 4 reduces the weight of the bottle cap main body 2, facilitating the discharge of internal gas when the liquid in the bottle body 1 boils. The design of the flat edge portion 7 enables the bottle cap main body 2 to better fit with the bottle body 1 when not exhausting air, preventing external air from entering. The setting of the handles 5 facilitates the flushing operation of the bottle cap main body 2 without worrying about the flushing liquid hurting the fingers. During the process of testing the ferrous iron content, it is necessary to prevent external air from entering the bottle body 1 during sample dissolution to avoid the oxidation of ferrous iron. The edge portion 7 of the special bottle cap main body 2 ensures this well, enabling the bottle body 1 during heating and sample dissolution to be more securely sealed and exhausted, and enabling the chemical analysis liquid adhered to it to be safely and quickly flushed at the end of heating, allowing the chemical analysis personnel to perform the detection more safely and accurately.

[0022] In some embodiments, the bottle cap bottom 3 is inverted conical, which is beneficial for the liquid in the bottle body 1 to condense after boiling and the liquid splashed onto the bottle cap bottom 3 to flow back into the bottle body 1.

[0023] In some embodiments, a hanging hole 6 is provided on the handle 5. Through the setting of the hanging hole 6, it is convenient to hang the bottle cap part after cleaning when in use.

[0024] In some embodiments, both the bottle cap main body 2 and the bottle cap bottom 3 are made of ceramic. The ceramic material is fired at high temperature and has extremely high physical and chemical stability. This stability ensures that the bottle cap can maintain its shape and performance in various environments and is not easily affected by external factors such as temperature and humidity.

[0025] Working principle or structural principle: During use, the bottom 3 of the inverted conical bottle cap replaces the traditional inverted pointed handle, enabling the liquid in the bottle body 1 to condense better after boiling and the liquid splashing onto the cap to flow back into the bottle body 1 more effectively. The design of the hollow bottle bottom 4 reduces the weight of the cap body 2, facilitating the discharge of internal gas when the liquid in the bottle body 1 boils. The design of the flat edge part 7 enables the cap body 2 to fit better with the bottle body 1 when not exhausting air, preventing external air from entering. The handle 5 is provided to facilitate the rinsing operation of the cap body 2 without worrying about the rinsing liquid hurting the fingers. During the process of testing the ferrous content, it is necessary to prevent external air from entering the bottle body 1 during sample dissolution to avoid the oxidation of ferrous. The edge part 7 of the special bottle cap body 2 ensures this well, thus enabling more secure sealing and exhaust of the bottle body 1 during heating sample dissolution, and quickly and safely rinsing the test solution adhering to it at the end of heating, enabling the laboratory personnel to conduct more secure and accurate detection.
