Description

Technical Field

[0001] This utility model relates to the field of bromide detection, and in particular to a bubble-isolated bromide detection reaction device. Background Technology

[0002] Bromide detection is crucial in many fields. For example, in environmental monitoring, accurate detection of bromide content in water, soil, and other environmental media is necessary to assess its impact on the ecological environment. In industrial production, for chemical processes involving bromides, precise determination of the bromide composition and concentration in raw materials and products is essential to ensure production quality and process control. Accurate bromide detection typically requires specialized reaction tubes. These reaction tubes, as key experimental instruments, provide a specific environment for the chemical reaction between bromides and corresponding detection reagents, and perform important functions such as sample injection, reaction observation, and result acquisition.

[0003] In existing bromide detection technologies, most commonly used detection reaction tubes are relatively simple single-chamber designs. Typically, an opening is made at the top or side of the reaction tube, through which a syringe or similar tool is used to inject the bromide sample into the tube, followed by the injection of the corresponding detection reagent.

[0004] The existing technology has the following drawbacks: it has only one chamber, and can only conduct experiments under a specific set of conditions at a time. If it is necessary to compare the effects of different conditions (different bromide concentrations, different reagent formulations, and different reaction times) on the reaction rate and reaction extent, it is necessary to repeat the experiment multiple times, setting different conditions one by one for detection. This not only consumes a lot of time and effort, but also makes it difficult to achieve real-time synchronous observation of the reaction under multiple conditions, which is not conducive to quickly and efficiently screening out the optimal detection conditions. Therefore, a bubble-isolated bromide detection reaction device is proposed to solve the above problems. Utility Model Content

[0028] 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.

[0029] Reference Figures 1-3This utility model provides an embodiment of a bubble-isolated bromide detection reaction device, including a peristaltic pump 1, also known as a roller pump or squeeze pump, which is a fluid transport device and is existing technology, so it will not be described in detail here. The outer wall of the peristaltic pump 1 is provided with a squeeze disc 2, which is in close contact with a flexible tube and performs a regular squeezing operation on the tube. Through this squeezing, the fluid inside the tube can be pushed sequentially, thereby achieving directional transport of the fluid from the inlet end to the outlet end. The surface of the squeeze disc 2 is in contact with a transport pipe 3. The delivery tube 3 is made of flexible tubing and will continuously allow liquid to pass through when not squeezed. The left end of the delivery tube 3 allows the bromide liquid to enter, and the right end of the delivery tube 3 is fixedly connected to a connecting tube 4. The connecting tube 4 has multiple main connections to the filter tube 11 on the reaction tube 5. The end of the connecting tube 4 is fixedly connected to the filter tube 11, which contains a porous filter membrane. When liquid containing air bubbles comes into contact with the filter membrane, the air bubbles, due to their relatively large size, cannot pass through these tiny pores. The bottom end of the filter tube 11 is fixedly connected to the reaction tube 5. A cavity 6 is formed in the inner wall of tube 5, which can be injected with bromide and reagents for subsequent mixing. A flow-disrupting rod 7 is fixedly connected to the inner wall of cavity 6. The flow-disrupting rod 7 can disrupt the originally relatively stable fluid flow state, so that different reactants are continuously cut, dispersed, and recombine in the tube, achieving more thorough and uniform mixing. A fixing tube 8 is fixedly connected to the bottom end of reaction tube 5, and a sealing gasket 9 is fixedly connected to the bottom end of fixing tube 8. A torsion cap 10 is threadedly connected to the outer wall of fixing tube 8. The outer wall of fixing tube 8 is provided with threads and the inner wall of torsion cap 10 is provided with... The thread allows the twist cap 10 to be quickly removed from the outer wall of the fixed tube 8. The bottom end of the sealing gasket 9 fits against the inner wall of the bottom end of the twist cap 10, which can seal the twist cap 10 and the fixed tube 8 to ensure that no liquid will flow out later. Multiple sets of baffle rods 7 are provided, and the multiple sets of baffle rods 7 are distributed in a stepped manner along the inner wall of the cavity 6. The baffle rods 7 at different positions can change the movement trajectory and distribution state of the bubbles in the cavity 6. The reaction tube 5 is made of transparent material, so the mixing of liquid in the reaction tube 5 can be observed.

[0030] Reference Figures 1-3 The surfaces of cavity 6, baffle rod 7, and fixed tube 8 are all coated with polytetrafluoroethylene (PTFE). PTFE has excellent chemical stability and extremely low surface energy. After the test, residual reagents and bromides can be easily removed by rinsing with water or simple detergent, greatly reducing the cleaning difficulty. Multiple sets of fixed tubes 8 are provided, and the multiple sets of fixed tubes 8 are evenly distributed on the outer wall of reaction tube 5. The delivery tube 3 is wound around the inner wall of peristaltic pump 1. The delivery tube 3 has an opening, which allows the delivery tube 3 to pass through peristaltic pump 1. The filter tube 11 and reaction tube 5 are connected.

[0031] Working principle: When reaction detection is required, simply start the peristaltic pump 1, causing the connected squeezing disc 2 to squeeze the contacting delivery pipe 3. Each squeeze by the squeezing disc 2 pushes the fluid in the delivery pipe 3 forward. When the squeezing disc 2 is released, the delivery pipe 3 returns to its original position due to its elasticity, allowing subsequent liquid to continuously enter the squeezed area. This cycle repeats, achieving stable directional delivery of fluid from the inlet to the outlet of the delivery pipe 3, continuously sending the liquid containing bromide and other components to be detected to the subsequent connecting pipe 4. The liquid delivered through the delivery pipe 3 enters the filter pipe 11 through the connecting pipe 4. Because the porous filter membrane has numerous tiny and uniformly distributed pores, when the liquid carrying air bubbles comes into contact with the filter membrane, the air bubbles, due to their relatively large size, cannot pass through these tiny pores and are trapped on one side of the filter membrane, while the liquid molecules can smoothly pass through the pores and continue to flow, thereby achieving the separation of air bubbles from the liquid and removing air bubbles, preventing air bubbles from entering the subsequent reaction pipe 5 and interfering with the bromide detection reaction.

[0032] Before the experiment, the reagent required for bromide detection can be injected into the cavity 6 in advance. During the process of liquid flowing into the cavity 6, multiple sets of baffle rods 7 set on the inner wall of the cavity 6 begin to play their role. They will disrupt the originally relatively stable fluid flow state, so that the liquid and reagent are continuously cut, dispersed and recombined during the flow. The baffle rods 7 at different positions change the movement trajectory and distribution state of any liquid and air bubbles remaining in the cavity 6, so as to promote a more thorough and uniform mixing of bromide and reagent, so as to ensure that the detection reaction can be carried out comprehensively and accurately.

[0033] Since the surfaces of cavity 6, baffle rod 7, and fixed tube 8 are all coated with polytetrafluoroethylene, which has extremely excellent chemical stability and very low surface energy, after the test, the reagents and bromides remaining on the surface of these components can be easily removed by rinsing with water or simple detergent. In addition, the peristaltic pump can quickly rinse the parts clean, which greatly reduces the cleaning difficulty of the entire device and makes it convenient to use the device again for bromide detection and other related operations.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
