Description

Technical Field

[0001] This utility model relates to the technical field of ammonia water detection equipment, and more specifically, to a rapid ammonia water concentration detection device. Background Technology

[0002] In many fields such as chemical engineering, environmental protection, and pharmaceuticals, ammonia is an important industrial raw material and chemical reagent. The accurate detection of its concentration plays a key role in ensuring the stability of the production process, product quality, and environmental safety. Accurately controlling the concentration of ammonia can effectively optimize the production process and avoid problems such as product quality fluctuations, equipment corrosion, and environmental pollution caused by improper ammonia concentration.

[0003] Currently, common methods for detecting ammonia concentration mainly include chemical titration, density measurement, and conductivity detection. While chemical titration provides relatively accurate results, it is cumbersome, has a long testing cycle, and requires specialized technicians, making it difficult to meet the needs of rapid detection. Density measurement is susceptible to interference from external factors such as temperature and pressure, resulting in lower measurement accuracy. Conductivity detection offers advantages such as fast detection speed and ease of operation, and is widely used for rapid ammonia concentration detection. However, most existing ammonia concentration detection devices based on conductivity detection principles can only detect single samples. When monitoring the concentration of multiple batches of ammonia, operators must repeatedly perform sampling, testing, and sample replacement, which is not only inefficient but also prone to human error during frequent operations. This fails to meet the practical needs of batch, rapid, and accurate ammonia detection in industrial production. Therefore, there is an urgent need to develop a rapid detection device capable of batch monitoring of ammonia to improve detection efficiency and accuracy while reducing labor costs and operational errors.

[0020] As a preferred embodiment of this utility model, a movable block is fixedly installed at the bottom end of the second hinge block, an arc-shaped block is fixedly installed on the outer surface of the movable block, a slider is fixedly installed at the bottom end of the movable block, a sliding groove is slidably connected to the outer surface of the slider, and the bottom end of the sliding groove is fixedly connected to the top end of the turntable.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This rapid ammonia concentration detection device, through the coordinated design of a stepper motor, cam, and turntable, achieves automated batch detection of ammonia. Compared with traditional detection devices, operators only need to place multiple batches of ammonia into sampling tubes at once, and the device can automatically transport the tubes to the detection position sequentially, eliminating the need for frequent manual sample replacement and significantly improving detection efficiency. The cooperation between the conductivity sensor and the data processor ensures accurate acquisition and rapid analysis of detection data, reducing human error. At the same time, the automated detection process reduces reliance on professional operators, effectively saving labor costs and providing a reliable technical solution for efficient and accurate detection of ammonia concentration in industrial production.

[0023] 2. This rapid ammonia concentration detection device, due to the design of its screw, movable rod, and movable block, effectively fixes multiple sampling tubes, significantly improving sample preparation efficiency and detection stability. Compared to traditional detection devices that fix single tubes one by one or lack fixing measures, this structure only requires the operator to drive the screw to rotate by turning the block, causing multiple arc-shaped blocks to move outward synchronously and clamp the tubes. This eliminates the need for individual operation, greatly shortening sample loading time. The secure fixing prevents the sampling tubes from tilting or shifting, ensuring precise contact between the probe and the solution during conductivity detection and improving the reliability of the detection data. Furthermore, the clamping force can be flexibly adjusted by rotating the screw to adapt to the fixing needs of different sized tubes, enhancing the device's versatility and providing efficient, stable, and reliable technical support for batch ammonia detection.

Detailed Implementation

[0032] 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.

[0033] like Figures 1 to 7 As shown, this utility model provides a rapid ammonia concentration detection device, comprising:

[0034] Chassis 1, with a fixing block 2 fixedly installed inside chassis 1;

[0035] The testing mechanism is located inside the fixed block 2;

[0036] A rotating mechanism is installed on the outer surface of the casing 1;

[0037] The rotating mechanism includes a stepper motor 3, the right side of which is fixedly connected to the left side of the housing 1. A rotating shaft 4 is fixedly sleeved at the output end of the stepper motor 3. A cam 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A circular block 6 is slidably connected to the outer surface of the cam 5. A fixing sleeve 7 is fixedly installed at the top of the circular block 6. A sampling test tube 8 is movably sleeved inside the fixing sleeve 7. A turntable 9 is fixedly sleeved on the outer surface of the fixing sleeve 7. A vertical shaft 10 is fixedly sleeved inside the turntable 9. The bottom end of the vertical shaft 10 is movably sleeved with the bottom end inside the housing 1.

[0038] When the stepper motor 3 is running, the rotating shaft 4 will drive the cam 5 to rotate. At this time, the groove on the cam 5 will squeeze and push the round block 6, so that the round block 6 drives the turntable 9 to rotate intermittently around the vertical axis 10 through the fixed sleeve 7. During this process, the sampling tube 8 will rotate under the drive of the fixed sleeve 7 to the bottom of the detection mechanism and stop, so as to monitor the concentration of ammonia. As the cam 5 rotates continuously, multiple sampling tubes 8 will move to the bottom of the detection mechanism in sequence for detection.

[0039] The testing institutions include:

[0040] Cylinder 11, the outer surface of cylinder 11 is fixedly sleeved with the inside of fixed block 2, and a moving plate 12 is fixedly installed at the output end of cylinder 11;

[0041] The conductivity sensor 13 has its outer surface fixedly sleeved with the inside of the moving plate 12, and a probe 14 is fixedly installed at the bottom of the conductivity sensor 13.

[0042] When the cylinder 11 is running, the motion plate 12 will drive the conductivity sensor 13 and the probe 14 to move downward. At this time, the probe 14 will be inserted into the ammonia water inside the sampling tube 8 during the downward movement. At this time, the conductivity sensor 13 will be able to detect the conductivity of the ammonia water.

[0043] The control panel 15 is fixedly installed on the outer surface of the chassis 1. The control panel 15 is equipped with a display, a controller and a data processor. The controller is electrically connected to the stepper motor 3 and the cylinder 11, and the conductivity sensor 13 is electrically connected to the data processor.

[0044] The design of the control panel 15 facilitates the operation of the equipment by the operator. The design of the display allows for a direct display of the test results. When the equipment is running, the controller will control the operation and stop of the stepper motor 3 and the cylinder 11. After the conductivity sensor 13 completes the conductivity detection of the ammonia water, it will transmit the electrical signal to the data processor.

[0045] The chassis 1 is equipped with a temperature sensor 16, which is electrically connected to the data processor.

[0046] Due to the design of the temperature sensor 16, it is able to monitor the ambient temperature in real time. This temperature data, along with the electrical signal detected by the conductivity sensor 13, is transmitted to the data processor. Since the ammonia concentration is easily affected by the ambient temperature, the data processor will use a temperature compensation algorithm to correct the conductivity detection value, and then convert it into an accurate ammonia concentration value and display it on the display.

[0047] The top of the chassis 1 is movably mounted with a top cover 17, and a first handle 18 is fixedly mounted on the outer surface of the top cover 17.

[0048] Due to the design of the top cover 17, it is easy for the operator to control the opening and closing of the top of the chassis 1. Due to the design of the first handle 18, it is easy for the operator to rotate the top cover 17.

[0049] Among them, a caster wheel 19 is fixedly installed at the bottom of the chassis 1, and a second handle 20 is fixedly installed on the outer surface of the chassis 1.

[0050] The design of the casters 19 allows the equipment to move flexibly, and the design of the second handle 20 allows the operator to move the equipment by pushing the second handle 20.

[0051] The housing 1 has a fixed rod 21 inside, and a cleaning block 22 is sleeved inside the fixed rod 21. The cleaning block 22 is located directly below the probe 14.

[0052] When the probe 14 moves downward, it will pass through the interior of the cleaning block 22. When the probe 14 completes the detection of ammonia and moves upward, ammonia will remain on the outer surface of the probe 14. At this time, the cleaning block 22 will be able to wipe away the residual ammonia on the probe 14 to prevent it from affecting the accuracy of the next detection.

[0053] Among them, a screw 23 is movably sleeved inside the top of the vertical shaft 10, and a screwing block 24 is fixedly installed at the top of the screw 23.

[0054] Since the screw 23 is movably connected to the vertical shaft 10, the screw 23 can rotate along the inside of the vertical shaft 10. Due to the design of the turning block 24, when the operator turns the turning block 24, the turning block 24 will drive the screw 23 to rotate.

[0055] Among them, the outer surface of the screw 23 is threaded with a moving ring 25, the outer surface of the moving ring 25 is fixedly installed with a first hinge block 26, the inside of the first hinge block 26 is hinged with a movable rod 27, and the end of the movable rod 27 away from the first hinge block 26 is hinged with a second hinge block 28.

[0056] Since the screw 23 is threadedly connected to the internal thread of the moving ring 25, when the screw 23 rotates, it will drive the moving ring 25 to move downward. At this time, the moving ring 25 will drive the movable rod 27 and the second hinge block 28 to move through the first hinge block 26.

[0057] Among them, a movable block 29 is fixedly installed at the bottom end of the second hinge block 28, an arc-shaped block 30 is fixedly installed on the outer surface of the movable block 29, a slider 31 is fixedly installed at the bottom end of the movable block 29, a slide groove 32 is slidably connected on the outer surface of the slider 31, and the bottom end of the slide groove 32 is fixedly connected to the top end of the turntable 9.

[0058] When the second hinge block 28 moves, it will drive the slider 31 to move outward along the inside of the slide groove 32 through the movable block 29. At the same time, the arc block 30 will move outward under the drive of the movable block 29. Then, the arc block 30 will contact the sampling tube 8 during the outward movement and fix the sampling tube 8.

[0059] Working principle and usage process of this utility model:

[0060] When operators need to monitor ammonia concentration in batches, they first place the sampling tubes 8 containing ammonia samples into the fixing sleeve 7 to ensure that the sampling tubes 8 are initially in place. Then, the operator turns the turning block 24, causing the turning block 24 to drive the screw 23 to rotate inside the top of the vertical shaft 10. As the screw 23 rotates, the moving ring 25 will move downward along the thread of the screw 23. At this time, the moving ring 25 will drive the movable rod 27 to move through the first hinge block 26. At the same time, the other end of the movable rod 27 will squeeze and push the second hinge block 28, causing the second hinge block 28 to drive the movable block 29 to move. Then, the movable block 29 will drive the slider 31 to move outward along the inside of the slide groove 32. Multiple movable blocks 29 move synchronously, and the arc-shaped blocks 30 on them gradually fit against the outer wall of the sampling tubes 8, applying uniform pressure to the sampling tubes 8 until all the sampling tubes 8 are firmly fixed.

[0061] Next, the operator sets the detection parameters via the control panel 15, including the single rotation angle of the stepper motor 3, the descent depth of the cylinder 11, and the data processing algorithm, to ensure that the equipment operation meets the detection requirements. Then, the operator presses the start button on the control panel 15, and the controller drives the stepper motor 3. At this time, the rotating shaft 4 drives the cam 5 to rotate continuously and uniformly. Due to the special design of the groove on the surface of the cam 5, its contour curve decomposes the rotational motion into a periodic "motion-stationary" process: In the motion phase, the groove curve pushes the circular block 6 to move radially, and the circular block 6 drives the turntable 9 to rotate around the vertical axis 10 via the fixed sleeve 7, causing the sampling tube 8 to rotate to the detection position; in the stationary phase, the groove curve disengages from the circular block 6, and the turntable 9 is precisely positioned and remains stationary, ensuring that the sampling tube 8 is stably positioned directly below the probe 14. After the sampling tube 8 stops, the controller controls the cylinder 11 to operate. At this time, the output end of the cylinder 11 drives the conductivity sensor 1 via the motion plate 12. 3 and probe 14 move downwards, and then probe 14 will vertically extend into the ammonia water inside the sampling tube 8 during the movement. Ammonia water is an electrolyte solution, and its concentration is related to its conductivity. The conductivity sensor 13 transmits the detected electrical signal to the data processor. Due to the design of the temperature sensor 16, the ambient temperature can be measured in real time. This temperature data is transmitted to the data processor along with the electrical signal detected by the conductivity sensor 13. Since the detection of ammonia water concentration is easily affected by the ambient temperature, the different evaporation rates of ammonia water at different temperatures will interfere with the detection results. The data processor uses a preset temperature compensation algorithm and combines real-time temperature data to correct the conductivity detection value. The electrical signal after temperature compensation correction is then converted into an accurate ammonia water concentration value by the data processor and displayed in real time on the screen of the control panel 15. With the cooperation of each component, through precise timing control, the intermittent transfer and sequential detection of the sampling tube 8 are realized, which greatly improves the efficiency of batch detection.
