Description

Technical Field

[0001] This utility model relates to a bubble removal structure for measuring drug solution in a concentration analyzer. Background Technology

[0002] Hydrogen peroxide (H2O2), due to its high oxidizing properties, can react with copper in copper-containing raw materials during etching to achieve the etching effect. The chemical equation for the reaction between copper and hydrogen peroxide is: 2Cu + 2H2O2 → 2CuO + 2H2O. This is a redox reaction, in which copper is oxidized to copper oxide (CuO), while hydrogen peroxide is reduced to water (H2O). Furthermore, copper ions can react with hydrogen ions (H+) in hydrogen peroxide to generate reactive oxygen species. However, continuous etching operations lead to a decrease in hydrogen peroxide concentration and an increase in copper ion concentration in the solution. For customers, reaching the maximum copper ion concentration threshold poses a production hazard, thus requiring concentration analysis equipment for real-time monitoring. However, for measurement accuracy, hydrogen peroxide, because its oxygen atom has a negative valence (not a stable oxidation state), continuously decomposes and generates bubbles, which affects measurement accuracy. Therefore, this application designs a bubble removal structure. Summary of the Invention

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A bubble removal structure for drug solution measurement in a concentration analyzer includes a main body. The main body has a stagnant cavity and an inlet channel, an outlet channel, and an outlet channel that are interconnected with the stagnant cavity. The outlet channel and the outlet channel are coaxially arranged and respectively located on both sides of the main body. The inlet channel is closer to the outlet channel and their axes are perpendicular. The inner diameters of the inlet channel and the outlet channel are equal and larger than the inner diameter of the outlet channel.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 This utility model discloses a bubble removal structure for measuring drug solution in a concentration analyzer. It includes a body 1, on which a stagnant chamber 11 is provided, and an inlet channel 12, an outlet channel 13, and an outlet channel 14 are interconnected with the stagnant chamber 11. The outlet channel 13 and the outlet channel 14 are coaxially arranged and respectively located on both sides of the body 1. The inlet channel 12 is closer to the outlet channel 14 and their axes are perpendicular. The inner diameters of the inlet channel 12 and the outlet channel 13 are equal, and the inner diameters of the inlet channel 12 and the outlet channel 13 are four times the inner diameter of the outlet channel 14.

[0018] The main body 1 in this utility model is a detachable structure. The detachable structure is used to drain the stagnant fluid chamber 11, which is mainly to facilitate the regular cleaning of the stagnant fluid chamber 11 and ensure that the device can operate stably for a long time.

[0019] The detachable structure is as follows: The main body 1 includes a main body 15, a locking sleeve 16, and a liquid outlet sleeve 17. The stagnant chamber 11, the liquid inlet channel 12, and the bubble outlet channel 14 are all located on the main body 15, and the liquid outlet channel 13 is located on the liquid outlet sleeve 17. The locking sleeve 16 and the liquid outlet sleeve 17 are both fitted onto the main body 15. The locking sleeve 16 locks the liquid outlet sleeve 17 in the same way as the locking structure of the existing drill bit sleeve. Both are achieved through the cooperation of conical surfaces and "notches". That is, several "notches" are provided in the axial direction of the liquid outlet sleeve 17. At the same time, conical surfaces are provided on the outer wall of the liquid outlet sleeve 17 and the inner wall of the locking sleeve 16. The locking sleeve 16 and the liquid outlet sleeve 17 are threaded together. Through the mutual cooperation of the conical surfaces of the two, the "notches" are tightened, thereby locking and fixing the liquid outlet sleeve 17 onto the main body 15.

[0020] The main body is provided with a pipe joint that communicates with the liquid inlet channel and the bubble outlet channel, and the liquid outlet sleeve is provided with a pipe joint that communicates with the liquid outlet channel. The pipe joints are used to connect the corresponding hoses.

[0021] When using this structure, it is as follows: Figure 3 The structure is vertically arranged, with the liquid entering through the inlet channel 12. Upon entering the stagnant chamber 11, the liquid experiences a change in flow velocity and a swirling effect. After entering the stagnant chamber 11, the flow velocity changes due to sufficient space within the chamber. Bubbles rise under buoyancy and move towards the bubble outlet channel 14. Since both the outlet channel 13 and the bubble outlet channel 14 are connected to the liquid delivery pipe 2 (equivalent to the main artery of the entire application system), the rapidly flowing liquid in the liquid delivery pipe 2 creates a pressure difference at the bubble outlet channel 14 when it passes through the bubble outlet channel 14 (i.e., the small diameter of the bubble outlet channel 14 is designed to better create this pressure difference). This pressure difference carries the bubbles from the bubble outlet channel 14 to the liquid delivery pipe 2, thus achieving effective separation of the bubbles and the liquid. The corresponding detector can be placed near the outlet channel 13. The bubble-free liquid flows into the TANK through the outlet channel (13), ensuring that the liquid entering the TANK is a pure liquid without bubbles, thus improving the accuracy of subsequent measurements.

[0022] The defoaming device is made of Teflon, which has excellent resistance to strong acids and alkalis, making it adaptable to various chemical solutions. Unlike PP or epoxy resin materials, it will not corrode when exposed to strong acids such as hydrofluoric acid (HF), thus avoiding the risk of chemical leakage and ensuring production safety. Furthermore, the long service life of Teflon reduces maintenance and replacement costs, improving the economic efficiency and reliability of the equipment.

[0023] Compared to traditional degassing modules, this defoaming device has an extremely low cost, less than 10% of that of a traditional degassing module, significantly reducing production costs and improving the economic efficiency of enterprises. Moreover, the defoaming device is small and convenient to use, with a compact structure, allowing for easy installation inside various concentration analyzers or related equipment without occupying excessive space. The installation process is simple and quick, improving the overall integration and flexibility of the equipment.

[0024] This structure can effectively remove air bubbles from the liquid, ensuring the stability of the liquid surface and the accuracy of the measurement, and has high practicality and promotional value.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
