Description

Technical Field

[0001] This utility model relates to the technical field of test tubes, and in particular to the technical field of rapid wastewater test tubes. Background Technology

[0002] Chloride ions are the most common anions in water and wastewater. Excessive concentrations of chloride ions can cause drinking water to taste bitter and salty, soil to become saline, pipes to corrode, plants to have difficulty growing, and harm human health. Therefore, it is essential to control the concentration of chloride ions emitted.

[0003] Hydrochloric acid and chloride-containing salts (such as sodium chloride) are common raw materials in various industrial production processes, especially in industries such as chemical synthesis, pharmaceuticals, printing and dyeing, machining, metallurgy, monocrystalline silicon, and food processing. These industries use large amounts of chlorine-containing raw materials, and their wastewater typically contains high concentrations of chloride ions. If the large amounts of chloride ions in this wastewater are not effectively removed and discharged into water bodies, they will cause serious and lasting harm to human health, soil, and the ecological environment. Many recently implemented local standards stipulate corresponding chloride ion concentration emission limits to restrict chloride ion discharge concentrations. However, because current chlorine wastewater treatment (chloride ion removal) technologies are not yet mature, the implementation of numerous standards will lead to wastewater from these industries failing to meet discharge standards, forcing these enterprises to suspend production or switch to other products. At the same time, excessively high chloride ion concentrations can cause severe corrosion of processes and treatment equipment. When the chloride content exceeds 1-3%, it makes it difficult to apply biological treatment technologies for organic wastewater, resulting in excessively high wastewater treatment costs and increasing enterprise costs.

[0004] Silver nitrate titration is a wastewater testing method primarily used to determine chloride ions or other substances that can react with silver ions to form a precipitate. This method involves reacting silver nitrate solution with chloride ions in the sample to produce a white silver chloride precipitate, which is then titrated to determine the chloride ion content. After sample preparation, titration is performed using a silver nitrate solution of a fixed concentration. During titration, the solution color changes, typically turning brick red at the endpoint. However, this method requires carrying test tubes, various reagents, burettes, and other equipment, making it inconvenient and cumbersome to operate on-site. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a rapid wastewater testing tube. The test tube contains reagents and the amount of reagents can be easily adjusted. It is easy to carry and operate.

[0006] To achieve the above objectives, this utility model proposes a rapid wastewater testing tube, comprising a test tube body, one end of which has a test tube opening, and a sealing cap membrane detachably connected thereto at the test tube opening. A chamber for containing reagents is provided between the sealing cap membrane and the test tube body. Several capsules are provided on the side of the sealing cap membrane near the test tube body, and the capsules are filled with reagents. The sealing cap membrane is also provided with an opening mechanism for opening each capsule.

[0007] Preferably, the opening mechanism includes a strip sealing strip, and the lower side of the bladder body is provided with a bladder opening. The strip sealing strip is sequentially laminated onto the surface of each bladder body and seals each bladder opening. One side of the sealing cap film is provided with a membrane opening for the strip sealing strip to extend out. The end of the strip sealing strip away from the membrane opening is bent and extends from the membrane opening to the upper side of the sealing cap film.

[0008] Preferably, the strip sealing strip extends to one end of the upper side of the sealing cover film and is provided with a second sealing film, the second sealing film being compositely connected to the upper side of the sealing cover film.

[0009] Preferably, the capsule is formed by an elastic membrane composited on the lower side of the sealing cap film and the sealing cap film together.

[0010] Preferably, the test tube also includes a test box, which has several placement holes adapted to the test tube body, and the test tube body is detachably disposed in the placement holes.

[0011] Preferably, the sealing cover film is a transparent film.

[0012] The beneficial effects of this novel rapid wastewater testing tube are as follows: This novel tube has multiple reagent-containing capsules on its sealed cap, and an opening mechanism for each capsule. Opening the corresponding capsule allows the reagent inside to flow into the tube for wastewater testing. Each capsule can carry the same type of reagent, thus controlling the reagent concentration by controlling the number of capsules opened. Alternatively, it can carry different weights of reagent, allowing for different tests by opening different capsules. This addresses various testing scenarios, making testing more convenient and simpler to operate. It saves time and reagents, reduces environmental pollution, lowers testing costs, and is portable, eliminating the need for additional equipment.

[0013] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0024] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0025] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0027] See Figures 1-6 This utility model discloses a rapid wastewater testing tube, comprising a test tube body 1, one end of which has a test tube opening, and a sealing cap 2 detachably connected to the test tube opening. A chamber for containing reagents is provided between the sealing cap 2 and the test tube body 1, and the chamber is filled with test reagents. Several capsules 21 are provided on the side of the sealing cap 2 near the test tube body 1, and each capsule 21 is filled with reagents. The sealing cap 2 is also provided with an opening mechanism for opening each capsule 21. In this embodiment, multiple capsules 21 containing reagents are provided on the sealing cap 2 of the test tube body 1, and an opening mechanism is provided to open each capsule 21. After the corresponding capsule 21 is opened, the reagent inside the capsule 21 can flow into the test tube body 1 for wastewater detection. Each capsule 21 can carry the same type of reagent, so the reagent concentration can be controlled by controlling the number of capsules 21 opened. It can also carry different weights of reagents, and different detections can be performed by opening different capsules 21, which can cope with various detection situations and make detection more convenient.

[0028] Preferably, in this embodiment, the test tube body 1 is filled with 1 mL of potassium chromate, while each capsule is filled with 0.2 mL of silver nitrate. The ratio of silver nitrate to potassium chromate is controlled by controlling the number of capsules 21 that are opened, thereby facilitating the detection of chloride ion concentration in the water.

[0029] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The capsule opening mechanism includes a strip sealing strip 3. Each capsule body 21 has an opening on its lower side. The strip sealing strip 3 is sequentially attached to the surface of each capsule body 21 and seals each opening. A sealing cap 2 has a membrane opening 22 on one side for the strip sealing strip 3 to extend from. One end of the strip sealing strip 3 away from the membrane opening 22 is bent and extends from the membrane opening 22 to the upper side of the sealing cap 2. In use, the capsule body 21 can be opened using the strip sealing strip 3 before opening the sealing cap 2, preventing contamination or leakage of the reagent inside the capsule body 21. When opening, the strip sealing strip 3 is directly pulled out. As it is pulled, the strip sealing strip 3 detaches sequentially from the surface of each capsule body 21, exposing the opening and allowing the reagent inside the capsule body 21 to flow out. The number of capsule bodies 21 opened can be controlled by controlling the amount of strip sealing strip 3 pulled out.

[0030] See Figure 3 , Figure 4 The strip sealing strip 3 extends to one end of the upper side of the sealing cap film 2 and is provided with a second sealing film 4, which is compositely connected to the upper side of the sealing cap film 2. The second sealing film 4 is used to seal the membrane opening 22 before use to prevent reagent leakage and contamination.

[0031] Preferably, the sealing cover 2 is a transparent film, which facilitates observation of the internal conditions. Example 2

[0032] See Figure 3 , Figure 5 Based on Embodiment 1, the capsule 21 is formed by an elastic membrane 6 composited on the lower side of the sealing cap 2 and enclosed by the sealing cap 2. The elastic membrane 6 has contractile properties; when the capsule opening is opened, the elastic membrane 6 can contract and compress the space of the capsule 21, facilitating the outflow of reagents from inside the capsule 21. Example 3

[0033] See Figure 7 It also includes a testing box 5, which has several placement holes 51 that fit the test tube body 1. The test tube body 1 is detachably placed in the placement holes 51, making it easy to store and carry.

[0034] The working process of this utility model:

[0035] In operation, this utility model discloses a rapid wastewater testing tube. Before opening the sealing cap 2, the capsule 21 can be opened using the strip sealing strip 3 to prevent contamination or leakage of the reagent inside the capsule 21. When opening, the strip sealing strip 3 is pulled out directly. After being pulled, the strip sealing strip 3 falls off the surface of each capsule 21 in sequence, thereby exposing the capsule opening and allowing the reagent inside the capsule 21 to flow out. The number of capsules 21 opened can be controlled by controlling the amount of strip sealing strip 3 pulled out, thereby controlling the amount of reagent until a suitable amount of reagent is adjusted. Then, the sealing cap 2 is opened, and wastewater can be added for testing.

[0036] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The internal components of the electric slide rail, cylinder, welding machine, electric telescopic rod and controller all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete the normal operation of them according to the existing technical manual. In addition, the circuit connection adopts the conventional connection method in the existing technology, and will not be described in detail here.

[0037] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
