Description

Technical Field

[0001] This utility model relates to the field of oscillator technology, and in particular to a constant temperature oscillator for chloride ion leaching in cement. Background Technology

[0002] The cement chloride ion dissolution shaker is a specialized experimental device used to determine the chloride ion content and dissolution characteristics in cement-based materials. Its core function is to accelerate and quantify the chloride ion dissolution process by simulating specific environmental conditions. This device typically consists of a temperature control system, a mechanical oscillation system, a sample container assembly, and a timing device. During operation, the pulverized cement sample and a specific leachate (such as deionized water or an acidic solution) are placed in a sealed container at a standard ratio. The mechanical oscillation system provides continuous and uniform oscillation energy, ensuring sufficient contact and reaction between the solid and liquid phases, promoting the migration of free and chemically bound chloride ions from the cement hydration products into the liquid phase. The temperature control system ensures that the experiment is conducted at a standard temperature, eliminating the interference of temperature fluctuations on the ion diffusion rate and dissolution equilibrium. Parameters such as oscillation frequency, amplitude, and duration are strictly set according to relevant testing specifications to ensure the repeatability and comparability of experimental results. After the experiment, the amount of chloride ions dissolved per unit mass of cement can be accurately calculated by chemical analysis of the leachate. This equipment plays an irreplaceable and important role in assessing the safety of marine sand concrete, analyzing the ability of admixtures to bind chloride ions, studying the critical concentration of steel corrosion, and predicting the durability of coastal structures. It provides key data support for the durability design and service safety assessment of cement-based materials.

[0003] In the existing technology, the standard procedure in the existing chloride ion leaching experiment is to place the cement sample block in a shaker container and dissolve the chloride ions in the liquid by shaking. In order to ensure the consistency of reaction conditions, the process needs to be carried out in a constant temperature environment. The usual practice is to set up a heater outside the container. However, this external heating method has a significant problem of heat loss: a large amount of heat generated by the heater will be directly dissipated into the surrounding air instead of being effectively absorbed by the container, resulting in low heat utilization. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature oscillator for the leaching of chloride ions in cement in order to solve the above-mentioned problems. This invention improves the problem that the large amount of heat generated by the heater is directly dissipated into the surrounding air instead of being effectively absorbed by the container, resulting in low thermal energy utilization.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a constant-temperature oscillator for chloride ion leaching in cement, comprising: Box; L-shaped cover plate, the L-shaped cover plate being movably hinged to the surface of the box body via a hinge shaft; A heater, which is fixedly connected to the inner wall of one side of the housing; The humidifier is provided in two parts, and the two humidifiers are respectively fixedly connected to the inner walls of the two sides of the box; A first fixing plate is fixedly connected to the adjacent ends of the two humidifiers; A sliding plate, the sliding plate being slidably connected to the upper surface of a first fixed plate via a reciprocating mechanism; and The container is mounted inside the sliding plate by two sets of snap-fit ​​mechanisms.

[0006] Preferably, the reciprocating mechanism includes a drive assembly and two sets of limiting assemblies.

[0007] Preferably, the drive assembly includes a drive slide plate, a cross slide hole, an I-beam block, a motor, a disc, and a push rod. The cross slide hole is opened at the upper end of the first fixed plate. The drive slide plate is slidably connected to the cross slide hole. The I-beam block is fixedly connected to the lower inner wall of the housing. The motor is fixedly connected to the upper end of the I-beam block. The disc is fixedly connected to the output end of the motor. The push rod is rotatably connected to the circumferential surface of the disc. The push rod is rotatably connected to the drive slide plate.

[0008] Preferably, each set of the snap-fit ​​mechanism includes a snap-fit ​​plate, a U-shaped snap-fit ​​block, and a torque spring. There are two U-shaped snap-fit ​​blocks and two torque springs.

[0011] Preferably, the surfaces of the two humidifiers are fixedly connected to an isolation plate, and both isolation plates are fixedly connected to the first fixing plate.

[0012] The beneficial effects of this utility model are: 1. In this solution, by integrating the heater and humidifier inside a sealed chamber, and using a sealing strip and an L-shaped cover to form a closed space, efficient utilization of thermal energy and the construction of a stable constant temperature environment are achieved. This structure effectively blocks the loss of heat to the external environment, so that the heat generated by the heater is fully used to maintain the temperature inside the chamber.

[0016] 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.

[0017] In practical implementation: such as Figures 1-4 As shown, a constant-temperature oscillator for chloride ion leaching in cement includes: Box 1; L-shaped cover plate 2, which is movably hinged to the surface of box 1 via a hinge shaft; Heater 6 is fixedly connected to the inner wall of one side of the housing 1; Humidifier 5, which is provided in two, and the two humidifiers 5 are respectively fixedly connected to the inner walls of the two sides of the box 1; The first fixing plate 7 is fixedly connected to the adjacent ends of the two humidifiers 5; Sliding plate 9, which is slidably connected to the upper surface of the first fixed plate 7 via a reciprocating mechanism; and Container 10 is mounted inside sliding plate 9 via two sets of snap-fit ​​mechanisms.

[0018] In this embodiment, an integrated box structure achieves efficient temperature control and oscillation operation. The device includes a box 1, with an L-shaped cover 2 hinged to its surface for easy opening and sealing. A heater 6 is fixedly connected to one inner wall of the box 1 for direct heating of the internal space. A humidifier 5 is fixedly connected to the inner walls of both sides of the box 1 to maintain humidity and prevent excessive evaporation of the solution. A first fixed plate 7 is fixedly connected to the near ends of the two humidifiers 5, serving as the core load-bearing structure. A sliding plate 9 is slidably connected to the upper surface of the first fixed plate 7 via a reciprocating mechanism to generate horizontal oscillation. A container 10 is installed inside the sliding plate 9 via two sets of snap-fit ​​mechanisms to hold cement samples and solutions. This structure integrates the heater 6 within the sealed box 1, confining heat within the box and utilizing it efficiently, effectively solving the problem of high heat loss in traditional external heating methods.

[0019] like Figures 1-4 As shown, the reciprocating mechanism includes a drive assembly and two sets of limiting assemblies. Each set of limiting assemblies includes a limiting slide hole, a limiting block 13, a limiting rod 14, and a second fixed plate 15. There are two second fixed plates 15, and both second fixed plates 15 are fixedly connected to the lower surface of the first fixed plate 7. The limiting rod 14 is fixedly connected to the adjacent ends of the two second fixed plates 15. The limiting slide hole is opened at the upper end of the first fixed plate 7. The limiting block 13 is fixedly connected to the lower end of the sliding plate 9. The limiting block 13 is slidably connected in the limiting slide hole. The limiting block 13 is slidably connected to the circumferential surface of the limiting rod 14. The drive assembly is connected to the sliding plate 9 to control the reciprocating motion of the sliding plate 9.

[0020] In this embodiment, each limiting assembly includes two second fixed plates 15 fixedly connected to the lower surface of the first fixed plate 7, a limiting rod 14 fixedly connected to the adjacent ends of the two second fixed plates 15, a limiting sliding hole opened at the upper end of the first fixed plate 7, and a limiting block 13 fixedly connected to the lower end of the sliding plate 9 and simultaneously slidably connected to the circumferential surface of the limiting sliding hole and the limiting rod 14. The driving assembly is connected to the sliding plate 9 to provide power. This dual limiting design ensures that the sliding plate 9 can only move smoothly along the direction defined by the limiting rod 14 during reciprocating motion, preventing swaying and jamming, and ensuring the stability and consistency of oscillation.

[0021] like Figures 1-4 As shown, the drive assembly includes a drive slide plate 12, a cross slide hole, an I-beam block 16, a motor 17, a disc 18, and a push rod 19. The cross slide hole is opened at the upper end of the first fixed plate 7. The drive slide plate 12 is slidably connected to the cross slide hole. The I-beam block 16 is fixedly connected to the lower inner wall of the housing 1. The motor 17 is fixedly connected to the upper end of the I-beam block 16. The disc 18 is fixedly connected to the output end of the motor 17. The push rod 19 is rotatably connected to the circumferential surface of the disc 18. The push rod 19 is rotatably connected to the drive slide plate 12.

[0022] In this embodiment, the drive assembly includes a drive slide plate 12 slidably connected to a cross-shaped sliding hole at the upper end of the first fixed plate 7, an I-beam block 16 fixedly connected to the lower inner wall of the housing 1, a motor 17 fixedly connected to the upper end of the I-beam block 16, a disk 18 fixedly connected to the output end of the motor 17, and a push rod 19 rotatably connected to the circumferential surface of the disk 18 and rotatably connected to the drive slide plate 12. When the motor 17 drives the disk 18 to rotate, the push rod 19 converts the circular motion into linear reciprocating motion of the drive slide plate 12 within the cross-shaped sliding hole, thereby driving the sliding plate 9 fixed to the drive slide plate 12 to perform precise reciprocating oscillation.

[0023] like Figures 1-4 As shown, each set of snap-fit ​​mechanisms includes a snap-fit ​​plate 11, a U-shaped snap-fit ​​block, and a torque spring. There are two U-shaped snap-fit ​​blocks and two torque springs. The snap-fit ​​plate 11 is rotatably connected to the sliding plate 9. The two torque springs are fixedly connected to the sliding plate 9 and fixedly connected to the snap-fit ​​plate 11. The two U-shaped snap-fit ​​blocks are fixedly connected to the surface of the container 10 and are matched with the snap-fit ​​plate 11.

[0024] In this embodiment, each locking mechanism includes a locking plate 11 rotatably connected to the sliding plate 9, two torque springs fixedly connected to the sliding plate 9 and fixed to the locking plate 11, and two U-shaped locking blocks fixedly connected to the surface of the container 10 and matching the locking plate 11. When installing the container, pressing the locking plate 11 causes it to rotate against the force of the torque spring, locking the U-shaped locking blocks on the container in place, and then releasing it. The locking plate 11 resets under the action of the torque spring, thus locking the container. Disassembly is performed in reverse, realizing the quick installation and removal of the container 10, which facilitates the handling of samples.

[0025] like Figures 1-4 As shown, a cover plate is threaded onto the upper part of the inner circumference of container 10.

[0026] In this embodiment, a cover plate is threadedly connected to the upper part of the inner circumference of container 10. This threaded connection ensures a reliable seal of container 10 during high-speed oscillation, effectively preventing solution leakage or the entry of external contaminants, and ensuring the accuracy of experimental results.

[0027] like Figures 1-4 As shown, a glass plate 3 is fixedly connected inside the L-shaped cover plate 2, and two handles 4 are fixedly connected to the surface of the L-shaped cover plate 2. A sealing strip is fixedly connected inside the box body 1.

[0028] In this embodiment: a glass plate 3 is fixedly connected inside the L-shaped cover 2, allowing the operator to directly observe the experimental process inside the chamber without opening the door. Two handles 4 are fixedly connected to the surface of the L-shaped cover 2, facilitating the opening and closing of the cover. A sealing strip is fixedly connected inside the chamber 1, which cooperates with the L-shaped cover 2 to ensure the airtightness of the chamber 1 when closed, thereby effectively maintaining a constant temperature and humidity environment inside the chamber.

[0029] like Figures 1-4 As shown, two humidifiers 5 are fixedly connected to the surfaces of two isolation plates 8, and both isolation plates 8 are fixedly connected to the first fixed plate 7.

[0030] In this embodiment, isolation plates 8 are fixedly connected to the surfaces of the two humidifiers 5, and both isolation plates 8 are fixedly connected to the first fixed plate 7. The function of the isolation plates 8 is to physically isolate the humidifiers 5 from the internal oscillation area, which can prevent the water vapor or possible condensation generated by the oscillation from directly affecting the normal operation of the humidifiers 5, and also protect the humidifiers 5 from the effects of mechanical vibration, thereby improving the reliability and service life of the equipment.

[0031] It should be noted that the humidifier 5, heater 6 and motor 17 used in this device are all existing technologies. The specific model of humidifier 5, heater 6 and motor 17 can be selected according to actual needs, and will not be elaborated on here.

[0032] In use, the operator first holds the handle 4 on the L-shaped cover 2 to open the chamber door, then rotates the locking plate 11 upwards to overcome the resistance of the torque spring, and inserts the sealed container 10 containing the cement sample and solution into the locking mechanism of the sliding plate 9 through the U-shaped locking block on its surface and locks it in place; then the L-shaped cover 2 is closed to compress the sealing strip and form a sealed space. After the equipment is started, the heater 6 heats the air inside the chamber 1, and the two humidifiers 5 work synchronously and are protected by the isolation plate 8 to maintain the humidity inside the chamber, creating a constant temperature and humidity environment for chloride ion dissolution. At the same time, the motor 17 drives the disc 18 to rotate, which drives the drive slide plate 12 to make linear reciprocating motion in the cross-shaped sliding hole through the push rod 19, thereby pushing the sliding plate 9 and the container 10 on it to move as a whole; the limiting block 13 at the lower end of the sliding plate 9 slides smoothly along the limiting sliding hole and the limiting rod 14 to ensure accurate and stable oscillation trajectory. During the experiment, the state of the container can be observed in real time through the glass plate 3. After the experiment, turn off the oscillation, heating and humidification functions in sequence. After the temperature inside the chamber drops to a safe range, open the chamber, release the locking mechanism and take out container 10 for subsequent solution analysis.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
