Description

Technical Field

[0001] This utility model relates to the field of chemical detection equipment technology, specifically an integrated lime effective calcium detector. Background Technology

[0002] In the process of determining the available calcium content in lime, it is usually necessary to mix the lime sample with a specific reagent to allow the available calcium to undergo a chemical reaction in order to determine its content. To ensure a complete reaction, the reaction solution is usually stirred.

[0003] Existing stirring methods typically employ fixed stirring blades or magnetic stirring. When using fixed stirring blades, the stirring range may be limited due to the fixed shape and installation position of the stirring blades. This uneven stirring may result in reactant concentrations in some areas being higher or lower than in other areas, affecting the sufficiency of the reaction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated lime effective calcium detector.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An integrated lime effective calcium detector includes a device body, a reaction cup is provided at the bottom of the device body cavity, a sealing cap is snapped on the top of the device body directly above the reaction cup to seal the reaction cup, and a detection probe for detecting the liquid in the reaction cup cavity is fixed on one side of the bottom of the sealing cap.

[0007] The bottom of the aforementioned cap is rotatably equipped with a stirring rod, and slide rods are slidably inserted at both ends of the stirring rod. A scraper is connected to the end of the slide rod away from the stirring rod. The distance between the side of the scraper located in front of the stirring rod in the direction of rotation and the center of the stirring rod shaft is greater than the distance between the side of the scraper located in the direction of rotation and the center of the stirring rod shaft.

[0008] Preferably, the scraper gradually thins at its front side along the rotation direction of the stirring rod, and the scraper has a planar plate structure or an arc-shaped plate structure.

[0009] Preferably, a groove is provided on the inner side of the stirring rod, and the sliding rod is slidably inserted into the groove.

[0010] Preferably, the slide bar sidewall is fitted with a pressure spring to restrict the slide bar from extending out of the slide groove.

[0011] Preferably, a retaining ring is fixed at the bottom of the cavity of the above-mentioned device to restrict the position of the reaction cup.

[0012] Preferably, a drive motor is fixed to the top of the cap, and the drive motor is used to drive the stirring rod to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The rotation speed of the stirring rod is controlled by the drive motor, so that the extension length of the scraper is adjusted according to the stirring speed, thereby providing different stirring intensities at different detection stages. The extension length of the scraper can also be adjusted as needed to stir the liquid at different locations.

[0015] 2. By setting a sliding mechanism (including a slide bar, a slide groove, and a pressure spring) between the scraper and the stirring rod, the scraper can dynamically adjust its position under the influence of liquid force and centrifugal force, so that it can adhere to the inner wall of the reaction cup during the stirring process, effectively scrape off the attached deposits, improve the stirring uniformity and cleaning effect, and thus improve the accuracy of the detection.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example

[0027] like Figures 1-4 As shown, the integrated lime effective calcium detector includes a device body 11. A reaction cup 13 is located at the bottom of the device body 11. A sealing cap 14, which seals the reaction cup 13, is snapped onto the top of the device body 11 directly above the reaction cup 13. A detection probe 141 for detecting the liquid inside the reaction cup 13 is fixed to one side of the bottom of the sealing cap 14. Sealing the reaction cup 13 with the sealing cap 14 effectively prevents external air, dust, or other impurities from entering the reaction cup 13, ensuring the stability of the detection environment. Simultaneously, the sealing structure reduces liquid evaporation or spillage, ensuring the accuracy and safety of the detection. The detection probe 141 is fixed to one side of the bottom of the sealing cap 14, allowing it to directly contact the liquid inside the reaction cup 13, avoiding detection errors caused by probe shaking or positional displacement.

[0028] The main body 11 of the device is placed on the platform of the intelligent lime activity detector, and the detection probe 141 penetrates the cover 14 and is connected to the intelligent lime activity detector.

[0029] In one embodiment, such as Figures 2-4 As shown, a stirring rod 22 is rotatably mounted on the bottom of the cap 14. Sliding rods 32 are slidably inserted into both ends of the stirring rod 22. A groove 23 is opened on the inner side of the stirring rod 22. The sliding rods 32 are slidably inserted into the groove 23. The design of the groove 23 makes the movement of the sliding rods 32 controlled, avoids irregular shaking of the scraper 31, and ensures the stability of the stirring process. A scraper 31 is connected to the end of the slide rod 32 away from the stirring rod 22. The distance between the side of the scraper 31 located in front of the stirring rod 22 in the direction of rotation and the center of the stirring rod 22's axis of rotation is greater than the distance between the side of the scraper 31 located in the rear of the stirring rod 22 in the direction of rotation and the center of the stirring rod 22's axis of rotation. When the scraper 31 is rotated by the stirring rod 22, because the side of the scraper 31 located in the front of the direction of rotation is farther from the axis of rotation of the stirring rod 22, the scraper 31 is pressed in the direction away from the center of the stirring rod 22's axis of rotation under the action of the liquid in the reaction cup 13 during the rotation process. The slide rod 32 extends out of the slide groove 23, and finally the side of the scraper 31 that is farther from the axis of rotation of the stirring rod 22 is attached to the inner side wall of the reaction cup 13. At this time, the scraper 31 continues to rotate, and can scrape off the material attached to the side wall of the reaction cup 13 during the rotation process.

[0030] By setting a pressure spring at the connection between the scraper 31 and the stirring rod 22, the force exerted by the liquid on the scraper 31 by the liquid in the reaction cup 13 changes when the stirring rod 22 and the scraper 31 rotate and the rotation speed changes. The force on the scraper 31 can be adjusted according to the rotation speed, which can overcome the force of the pressure spring and cause the scraper 31 to extend. The extension length varies depending on the speed. Thus, by changing the rotation speed of the stirring rod 22 and the scraper 31, the position of the scraper 31 can be changed. By changing the position of the scraper 31, the scraper 31 can be used to stir different areas, improving the stirring effect. Furthermore, when it is necessary to scrape the inner wall of the reaction cup 13, the rotation speed can be increased to cause the scraper 31 to extend and scrape the inner wall of the reaction cup 13.

[0031] In one embodiment, such as Figures 3-4 As shown, the scraper 31 gradually thins along the rotation direction of the stirring rod 22, and the scraper 31 has a flat plate-like structure or an arc-shaped plate-like structure. This design helps to reduce the resistance when the scraper 31 scrapes the deposits on the inner wall of the reaction cup 13, thereby improving the scraping effect. At the same time, the arc-shaped plate-like structure can fit more closely to the inner wall of the reaction cup 13, allowing the scraper 31 to act more evenly on the liquid during the stirring process, thus improving the overall stirring effect of the stirring 31.

[0032] In one embodiment, such as Figure 3 As shown, a pressure spring is provided on the side wall of the slide rod 32 to limit the slide rod 32 from extending out of the slide groove 23. The function of the pressure spring is to provide a certain retraction force when the scraper 31 is subjected to liquid resistance or the rotation speed of the stirring rod 22 changes, so that the scraper 31 will not extend excessively and thus avoid affecting the stirring effect.

[0033] In one embodiment, such as Figure 2 As shown, a retaining ring 12 is fixed at the bottom of the cavity of the device body 11 to restrict the position of the reaction cup 13. The retaining ring 12 can ensure that the reaction cup 13 remains stable during the detection process and will not shift or shake due to stirring or other external forces, thereby ensuring the stability of the detection process.

[0034] In one embodiment, such as Figures 2-3 As shown, a drive motor 21 is fixed on the top of the cover 14. The drive motor 21 is used to drive the stirring rod 22 to rotate. The drive motor 21 can adjust the rotation speed of the stirring rod 22 by adjusting the motor speed, thereby changing the extension degree of the scraper 31 during the stirring process, making the stirring process more flexible.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
