Description

Technical Field

[0001] This utility model relates to the field of concentration detection technology, specifically a portable rapid ammonia concentration detection device. Background Technology

[0002] In chemical production, ammonia water is an important raw material or intermediate product. The precise control of its concentration directly affects product quality and production efficiency. For example, in fertilizer production, the concentration of ammonia water needs to be strictly controlled to ensure the reasonable content of nitrogen in the fertilizer. The requirements for ammonia water concentration vary greatly in different process stages, from low concentrations used in some fine chemical reactions to high concentrations used in specific synthesis processes. Accurate knowledge of the ammonia water concentration is essential to ensure the stable operation of the process flow and avoid product defects or production accidents caused by concentration deviations.

[0003] Classic acid-base titration requires professional operation and involves cumbersome steps. From sampling and reagent preparation to titration and subsequent data calculation, the entire process is time-consuming and cannot meet the needs of rapid on-site testing. The chemical reagents used in the titration process may pose certain dangers, and the operation requires a high level of skill. Some large-scale testing equipment based on principles such as spectral analysis, although highly accurate, is bulky, expensive, and requires a professional installation environment and maintenance, making it not portable.

[0004] While some existing portable ammonia concentration detection devices offer a degree of portability, they fall short in terms of detection accuracy, speed, and stability. They cannot perform rapid detection effectively and are not easily portable. Therefore, we propose a portable rapid ammonia concentration detection device. Utility Model Content

[0017] Compared with the prior art, this utility model provides a portable rapid ammonia concentration detection device, which has the following beneficial effects:

[0018] 1. This portable ammonia concentration rapid detection device, in order to better and faster detect ammonia concentration, is designed with a detection component. First, the arc-shaped cover is rotated, and with the help of the hinge shaft, the arc-shaped cover is opened on the cylinder. The ammonia sample to be tested is dripped into the glass cover by the operator. Then, the specific wavelength light emitted by the LED light source passes through the conical cover and through the glass cover, and is received by the photodetector. Ammonia molecules will absorb and scatter the light, causing the light intensity received by the photodetector to change. By using the pre-established correspondence between light intensity and ammonia concentration, the ammonia concentration can be quickly calculated. The value is displayed by the controller. With the help of fixed magnets and movable magnets, the arc-shaped cover and the cylinder are more firmly attached.

The device can be easily lifted by holding the handle. When the cover is closed and one side is aligned with the long strip, the baffle on the screw is rotated to clamp the other side of the cover, preventing it from loosening during movement. When the cover is fully open and horizontal, rotating the threaded cylinder and then the threaded column keeps the open cover stable, facilitating the detection operation and making it easier to carry the device.

[0029] Please see Figure 1 - Figure 6 This utility model provides a technical solution:

[0030] A portable rapid ammonia concentration detection device includes an equipment box 1, and a controller 2 is fixedly installed inside the equipment box 1.

[0031] In one embodiment of this utility model, a detection component 3 is provided on the controller 2. The detection component 3 includes a cylinder 31. The cylinder 31 is fixedly installed on the side wall of the controller 2. A round cover 32 is snapped onto the other end of the cylinder 31. A hinge shaft 33 is fixedly installed on the cylinder 31. An arc-shaped cover 34 is rotatably installed on one end of the hinge shaft 33. In addition, the size of the arc-shaped cover 34 is adapted to the arc-shaped opening in the middle of the cylinder 31, so as to better cooperate with the round cover 32 to close the cylinder 31. An LED light source 35 is fixedly installed inside the end of the cylinder 31 away from the controller 2. A photodetector 36 is fixedly installed on the side wall of the controller 2. The photodetector 36 is located inside the cylinder 31. The arc-shaped inner wall of the cylinder 31 is fixedly installed. A conical cover 37 is fixedly installed. In addition, the circular cross-section centers of the cylinder 31, the circular cover 32, the LED light source 35, the photodetector 36, and the conical cover 37 are coaxial, so as to better perform the detection. Two sets of conical covers 37 are provided, and the two sets of conical covers 37 are mirror images of each other at both ends inside the cylinder 31 with the vertical center line of the cylinder 31 as the mirror axis. A glass cover 38 is fixedly installed in the middle of the cylinder 31. The glass cover 38 is made of transparent glass and contains the ammonia sample to be tested. A fixed magnet 39 is fixedly installed in the middle of the arc-shaped side wall of the cylinder 31. A movable magnet 310 is fixedly installed at the other end of the arc-shaped cover 34. The magnetic properties of the fixed magnet 39 and the movable magnet 310 are opposite at the adjacent ends.

[0032] In this embodiment, before testing, the arc-shaped cover 34 tightly covers the arc-shaped opening in the middle of the cylinder 31, sealing the cylinder 31 together with the round cover 32. When ammonia concentration testing is required, the operator manually operates the device, holding the arc-shaped cover 34 and rotating it around the hinge shaft 33 to open it from the cylinder 31, exposing the testing area inside the cylinder 31. Then, using a dropper or other suitable tool, an appropriate amount of ammonia sample is precisely drawn and dripped into the glass cover 32 made of transparent glass. Inside the cylinder 31, after the sample is dropped into the glass cover 38, the arc-shaped cover 34 is closed. At this time, the fixed magnet 39 and the movable magnet 310 approach each other. Since their adjacent ends have opposite magnetic properties, they generate a magnetic force that attracts each other, thus making the arc-shaped cover 34 and the cylinder 31 fit tightly together, further ensuring the sealing and stability of the detection component 3. The controller 2 sends a command to the LED light source 35 according to the preset program, causing it to emit light of a specific wavelength. This light propagates along the axial direction of the cylinder 31, first passing through the conical cover 37. The conical cover 37 makes the light... The light rays are directed more concentratedly and stably towards the glass cover 38. As the light passes through the glass cover 38, it interacts with the ammonia sample inside. Ammonia molecules absorb some of the light energy and scatter the light in different directions. The light, after passing through the sample, continues to propagate and is eventually received by the photodetector 36 located on the side wall of the controller 2 and inside the cylinder 31. The photodetector 36 converts the received light signal into an electrical signal and transmits it to the controller 2. Due to the absorption and scattering of light by the ammonia molecules, the light intensity received by the photodetector 36 changes compared to the initial light intensity emitted by the LED light source 35. The controller 2 has pre-stored a large amount of experimentally determined data on the correlation between light intensity and ammonia concentration. Upon receiving the electrical signal from the photodetector 36, the controller 2 quickly compares the light intensity change with the pre-stored data using a built-in algorithm to calculate the current concentration of the ammonia sample. The calculation result is clearly displayed digitally on the screen of the controller 2 for easy reading by staff. After the test is completed, the ammonia sample is manually cleaned to protect the detection component 3 and facilitate future use.

[0033] In one embodiment of this utility model, a portable component 4 is provided on the device box 1. The portable component 4 includes a base column 41. The base column 41 is fixedly installed on the outer wall of the bottom end of the device box 1. Four sets of base columns 41 are provided to make the device body more stable. In addition, a handle 42 is fixedly installed on the outer wall of one end of the device box 1. A cover plate 43 is hinged to the top of the other end of the device box 1. A long strip plate 44 is fixedly installed inside the end of the device box 1 near the handle 42. In addition, a screw 45 is fixedly installed on the top of the end of the device box 1 near the handle 42. A baffle 46 is threaded on the screw 45. Two sets of screws 45 and baffles 46 are provided to better fix the cover plate 43. In addition, a threaded cylinder 47 is threaded inside the other end of the cover plate 43. A threaded post 48 is threaded inside the threaded cylinder 47 to better place the cover plate 43.

[0034] In this embodiment, when the device body needs to be placed on the workbench before testing, the four sets of base columns 41 are evenly distributed and jointly support the equipment box 1, ensuring that the device body can be placed horizontally and stably. This prevents the device from shaking or even tipping over due to unstable placement, which could affect the testing operation or damage the equipment. When it is necessary to move the device body, the operator can directly grasp the handle 42 fixed to one end of the outer wall of the equipment box 1. By lifting the handle 42, the entire device body can be easily lifted and moved to the desired position, achieving convenient carrying. Before this, the cover plate 43 needs to be closed, so that one side is tightly attached to the long strip 44. Then, rotate the baffle 46 on the screw 45, gradually moving it closer to the other side of the cover plate 43 until the baffle 46 firmly clamps the other side of the cover plate 43. This allows for easy movement. During the process, the cover plate 43 will not loosen or open due to shaking or bumping, effectively protecting the internal components of the equipment box 1. When the inspection operation is required at the inspection location, the staff opens the cover plate 43. As the cover plate 43 rotates around the hinge point, when the cover plate 43 is fully opened and horizontal, it needs to be supported and fixed in order to keep the cover plate 43 stable. The staff first rotates the threaded cylinder 47 to adjust its extension length. Then, the threaded column 48 is rotated inside the threaded cylinder 47 so that the threaded column 48 gradually extends and contacts the support surface (such as the workbench). By adjusting the matching length of the threaded cylinder 47 and the threaded column 48, the cover plate 43 remains stable in the open state, providing a reliable working platform for the inspection operation, thereby achieving the purpose of better carrying and using the device body.

[0035] All electrical components appearing in this application are electrically connected to the controller 2, and the controller 2 is a conventional known device that can control the LED light source 35 and the photodetector 36. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all connected by conventional methods such as riveting and welding that are mature in the prior art. Furthermore, the machinery, parts and equipment are all of conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
