Description

Technical Field

[0001] This utility model relates to the field of ultrapure water technology, specifically a portable pH electrode for use in ultrapure water applications. Background Technology

[0002] In the field of ultrapure water, accurate pH measurement is crucial for many processes and quality control. Ultrapure water has extremely low ion concentration and extremely high resistivity, which makes traditional pH electrodes prone to problems such as unstable measurement values ​​and long response times when measuring ultrapure water. Therefore, the development of a dedicated pH electrode suitable for ultrapure water applications has become an urgent need in the industry.

[0003] In the prior art, such as the pH electrode disclosed in application number CN202421210051.2, which can be used in ultrapure water applications, an electrode tube is included. A ground joint is fixedly connected to the bottom of the electrode tube, and a sensitive membrane is sleeved on the bottom of the electrode tube. A crank arm is fixedly connected to the left side of the electrode tube, and a flexible tube is fixedly connected to the top of the crank arm. By sliding an outer ring up and down, the outer ring drives a limiting ring to slide in the groove with a ball bearing, squeezing the flexible tube behind the collar. Due to the nature of the flexible tube, the ball bearing contracts, thus limiting the flow rate of the potassium chloride solution inside the flexible tube.

[0004] In the published application document with application number CN202421210051.2, a groove is fixedly disposed between the connecting ring and the collar, and the balls slide within the groove to compress the hose and control the flow rate. However, due to the fixed structure of the groove, the degree of compression of the hose by the balls is greatly limited, making it impossible to achieve more precise and smaller flow rate control.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a portable pH electrode for use in ultrapure water applications, in order to solve the problems mentioned in the background art.

[0007] To solve the above technical problems, this utility model provides a portable pH electrode for use in ultrapure water applications, including an electrode tube, a connecting tube fixedly installed on the outer wall of the electrode tube, a connecting ring fixedly installed on the top of the connecting tube, a flexible tube inserted into the top of the connecting ring, and a disassembly and flow rate control mechanism installed on the outer wall of the flexible tube. The disassembly and flow rate control mechanism includes an adjustment plate. The inner walls of both ends of the adjustment plate are provided with grooves. Slider blocks are slidably installed on the inner walls of the two grooves. An adjustment rod is also rotatably connected to the adjustment plate. A lead screw nut is provided in each of the two sliders. The two lead screw nuts cooperate with the adjustment rod. Push-pull rods are rotatably installed on both ends of the outer walls of the sliders. Flow rate control components are rotatably installed on the side ends of the push-pull rods. The flow rate control component includes an outer clamping rod rotatably mounted on the side wall of the middle section of the regulating plate, and an inner clamping rod rotatably mounted at the connection between the outer clamping rod and the regulating plate.

Both the outer and inner clamping rods have connecting plates fixedly installed on their outer walls, and the side walls of the connecting plates are rotatably connected to the side ends of the push-pull rods.

[0008] Furthermore, the adjusting rod includes a torsion ring, a forward lead screw is fixedly installed on the side wall of the torsion ring, a rotating rod is fixedly installed on the side end of the forward lead screw, a reverse lead screw is fixedly installed on the side end of the rotating rod, the outer wall of the reverse lead screw passes through the inner wall of the adjusting plate and is rotatably connected to the inner wall of the adjusting plate, the outer walls of the forward lead screw and the reverse lead screw are respectively rotatably connected to the inner walls of two sliding grooves, and an adjusting groove is opened on the side end of the adjusting plate, the outer wall of the adjusting groove is rotatably connected to the side wall of the torsion ring.

[0009] Furthermore, a ground joint is fixedly connected to the bottom of the electrode tube, a sensitive membrane is sleeved on the bottom of the electrode tube, and rubber pads are provided on the inner walls of the outer clamping rod, inner clamping rod, left clamping plate, and right clamping plate.

[0011] Furthermore, a rotating shaft is rotatably mounted on the inner wall of the end of the push-pull rod away from the slider, and the side wall of the rotating shaft is rotatably connected to the outer wall of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the easy-to-disassemble and flow rate control mechanism, the rotation of the adjusting rod drives the slider to move in the trough, and then the push-pull rod causes the outer clamp rod and the inner clamp rod to rotate relative to each other to squeeze the hose. Since the inner clamp rod can slide on the inner wall of the outer clamp rod, the degree of squeezing can be adjusted more flexibly, thereby achieving more precise flow rate control of potassium chloride solution in the hose and better meeting the accurate pH measurement requirements in ultrapure water applications. 2. The spring force allows the left and right clamps to easily clamp and release the electrode tube. During installation, simply align the gap between the left and right clamps with the electrode tube and press to achieve a stable connection. During disassembly, the electrode tube can be removed by overcoming the spring force, which improves the efficiency of disassembly and assembly and makes it more convenient for users.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-4This utility model provides a technical solution: a portable pH electrode for use in ultrapure water applications, comprising an electrode tube 1, a connecting tube 4 fixedly installed on the outer wall of the electrode tube 1, a connecting ring 5 fixedly installed on the top of the connecting tube 4, a flexible tube 6 inserted into the top of the connecting ring 5, and a disassembly and flow rate control mechanism 7 installed on the outer wall of the flexible tube 6. The disassembly and flow rate control mechanism 7 includes an adjusting plate 701, with grooves 7015 formed on the inner walls of both ends of the adjusting plate 701, and sliders 7012 slidably installed on the inner walls of both grooves 7015. An adjusting rod 704 is also rotatably connected to the adjusting plate 701, and the two sliders 701... Both slide blocks 7012 and 7013 are equipped with lead screw nuts, which cooperate with the adjusting rod 704. When adjusting the flow rate, the slide block 7012 slides within the slide groove 7015. Push-pull rods 7013 are rotatably mounted on both ends of the outer wall of the slide block 7012, and a flow rate control component 703 is rotatably mounted on the side end of the push-pull rod 7013. Simultaneously, the push-pull rod 7013 is rotatably connected to the connecting plate 7034 of the flow rate control component 703, ensuring the stability and reliability of power transmission from the adjusting rod 704 to the flow rate control component 703. During flow rate adjustment, the movements of all components are coordinated and consistent. 703 includes an outer clamping rod 7031 rotatably mounted on the side wall of the middle section of the adjusting plate 701, and an inner clamping rod 7032 rotatably mounted at the connection between the outer clamping rod 7031 and the adjusting plate 701. A clamping groove 7033 is formed on the inner wall of the outer clamping rod 7031, and the inner wall of the clamping groove 7033 can slide against the outer wall of the inner clamping rod 7032. The adjusting rod 704 drives the slider 7012 to move in the sliding groove 7015, which in turn causes the outer clamping rod 7031 and the inner clamping rod 7032 to rotate relative to each other, compressing the hose 6. Because there is a sliding fit between the inner clamping rod 7032 and the outer clamping rod 7031, it allows for more flexible... The degree of compression on the hose 6 can be flexibly adjusted to achieve more precise flow rate control than existing technologies, meeting the requirements for precise adjustment of solution flow rate in ultrapure water pH measurement. This allows the outer clamping rod 7031 and the inner clamping rod 7032 to compress the hose 6 over a wider range, enabling not only larger flow rate adjustments but also more minute flow rate control. This provides a wider range of flow rate options for ultrapure water pH measurement under different operating conditions. The outer walls of both the outer clamping rod 7031 and the inner clamping rod 7032 are fixedly equipped with connecting plates 7034, and the side walls of the connecting plates 7034 are rotatably connected to the side end of the push-pull rod 7013.

[0017] Please see Figure 2This utility model provides a technical solution: a portable pH electrode for use in ultrapure water applications, comprising an adjustable plate 701 with a detachable assembly 702 rotatably mounted on the side away from the flow rate control component 703. The detachable assembly 702 includes a left clamping plate 7021 and a right clamping plate 7022 rotatably mounted on the side wall of the adjustable plate 701. An extension plate 7024 is integrally formed on the side wall of both the left clamping plate 7021 and the right clamping plate 7022. A spring 7023 is fixedly connected to the side wall of the extension plate 7024 near the adjustable plate 701. The side end of the spring 7023 is fixedly connected to the outer wall of the adjustable plate 701. The left clamp 7021 and right clamp 7022 are connected to the adjusting plate 701 through these springs 7023. Simply align the gap between the left clamp 7021 and right clamp 7022 with the electrode tube 1 and apply a certain pressure. The spring 7023 will deform elastically, thereby clamping the electrode tube 1 between the left clamp 7021 and right clamp 7022, achieving quick installation, saving installation time and effort, and improving work efficiency. When disassembly is required, it is only necessary to overcome the elastic force of the spring 7023 and remove the electrode tube 1 from between the left clamp 7021 and right clamp 7022. The operation is simple and convenient.

[0018] Please see Figure 3 and Figure 4 This utility model provides a technical solution: a portable pH electrode for use in ultrapure water applications. The adjusting rod 704 includes a torsion ring 7041. A forward lead screw 7042 is fixedly mounted on the side wall of the torsion ring 7041. A rotating rod 7043 is fixedly mounted on the side end of the forward lead screw 7042. A reverse lead screw 7044 is fixedly mounted on the side end of the rotating rod 7043. The outer wall of the reverse lead screw 7044 passes through the inner wall of the adjusting plate 701 and is rotatably connected to the inner wall of the adjusting plate 701. The forward lead screw 7042 and the reverse lead screw 7044 are respectively engaged with two lead screw nuts. The outer walls of the forward lead screw 7042 and the reverse lead screw 7044 are respectively connected to... The inner walls of the two slide grooves 7015 are rotatably connected. An adjustment groove 7011 is provided on the side end of the adjustment plate 701. The outer wall of the adjustment groove 7011 is rotatably connected to the side wall of the torsion ring 7041. When the operator rotates the torsion ring 7041, thanks to the thread characteristics of the forward screw 7042 and the reverse screw 7044, the two sliders 7012 will move towards or away from each other along the slide grooves 7015 under the interaction of the threads. This allows for more precise control of the movement distance and direction of the sliders 7012, thus providing a reliable guarantee for the subsequent precise adjustment of the solution flow rate in the hose 6 by driving the flow rate control component 703 through the push-pull rod 7013.

[0019] Please see Figure 2 , Figure 3This utility model provides a technical solution: a portable pH electrode for use in ultrapure water applications, comprising an electrode tube 1 with a ground joint 2 fixedly connected to its bottom, a sensitive membrane 3 sleeved on the bottom of the electrode tube 1, and a rotating shaft 7014 rotatably mounted on the inner wall of the end of the push-pull rod 7013 away from the slider 7012. The side wall of the rotating shaft 7014 is rotatably connected to the outer wall of the connecting plate 7034. Rubber pads are provided on the inner walls of the outer clamping rod 7031, inner clamping rod 7032, left clamping plate 7021, and right clamping plate 7022. Due to the flexibility of the rubber pads, they can deform to a certain extent according to the shape of the object being clamped, conforming to the surface of the object and increasing the contact area for clamping, thereby enhancing the stability of clamping. The surface of the rubber pads has an integrally formed anti-slip texture, further improving the anti-slip and clamping effect.

[0020] Working principle: When the left clamping plate 7021 and right clamping plate 7022 of the detachable assembly 702, which is rotatably installed on the side of the adjusting plate 701 away from the flow rate control assembly 703, are aligned with the electrode tube 1, the electrode tube 1 is pressed down. Under the action of the spring 7023, which is fixedly connected to the outer wall of the extension plate 7024 and the adjusting plate 701, the left clamping plate 7021 and right clamping plate 7022 hold the electrode tube 1, so that the hose 6 is stably connected. When it is necessary to control the flow rate of potassium chloride solution in the hose 6, the torsion ring 7041 of the adjusting rod 704 in the detachable and flow rate control mechanism 7 is twisted, which drives the adjusting rod 704, which is composed of a forward screw 7042, a rotating rod 7043 and a reverse screw 7044, to rotate. Since the forward screw 7042 and the reverse screw 7044 respectively interact with the sliding grooves 704 on the inner walls of both ends of the adjusting plate 701, the adjustment rod 704 rotates. The slider 7012, which is slidably installed inside the 15, is engaged with a screw nut. When the adjusting rod 704 is rotated, the two sliders 7012 will move closer to each other. The push-pull rods 7013, which are rotatably installed at both ends of the outer wall of the slider 7012, will move accordingly. The push-pull rods 7013 are rotatably connected to the connecting plate 7034 in the flow rate control component 703 through the rotating shaft 7014. This will drive the outer clamping rod 7031, which is rotatably installed on the side wall of the middle section of the adjusting plate 701, and the inner clamping rod 7032, which is rotatably installed at the connection point with it, to rotate relative to each other around the connection point of the adjusting plate 701, thereby squeezing the hose 6. Since the inner clamping rod 7032 can slide in the clamping groove 7033 on the inner wall of the outer clamping rod 7031, the degree of squeezing on the hose 6 can be adjusted more flexibly to achieve precise flow rate control. When disassembling, the electrode tube 1 can be removed by overcoming the elastic force of the spring 7023.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
