Description

Technical Field

[0001] This invention relates to the field of materials testing technology, and in particular to a testing device for detecting chemical products in a flonicamid reaction vessel. Background Technology

[0002] The production process of flonicamid requires the use of multiple detection devices to detect the chemical products in the reaction vessel. Among them, the online infrared spectrometer can monitor the reaction process such as amidation and hydrolysis, and determine the reaction endpoint in real time. Before detection, the humidity of the desiccant needs to be checked, and then the sample support plate with the sample placed on it needs to be inserted into the detection area for detection.

[0003] For example, patent CN113899711A discloses a spectrometer with a dual-frame opto-mechatronic integrated structure, suitable for spectrometers that use filters for spectral dispersion, especially near-infrared spectrometers for online analysis. Belonging to the field of spectrometers, it is mainly composed of two main structures: an electromechanical spectral modulation frame and an optoelectronic frame. The electromechanical spectral modulation frame includes a main frame, a spectral modulation mechanism, and a sampling mirror; the optoelectronic frame consists of upper and lower circuit boards, middle and bottom borders, a light source and sampling illumination system, and sensor components. The combination of the two frames meets the optical path requirements for illumination and sampling of the spectrometer. The structure is neat, simple, robust, and compact, facilitating installation, debugging, and fault detection, and is particularly suitable for online real-time detection of materials on production lines.

[0004] However, the dehumidifier will continue to run after the online infrared spectrometer is finished, and the power supply needs to be kept on. However, in actual operation, the staff may unplug the power cord due to lack of experience or operation error, which will interrupt the dehumidification function and result in high humidity inside the online infrared spectrometer, causing the internal electronic components to become damp and damaged. Summary of the Invention

[0005] In view of this, the present invention provides a detection device for detecting chemical products in a flonicamid reaction vessel. It achieves automatic limit protection of the power cord during dehumidifier operation through limiting electromagnets, limiting baffles, and position limiting rods, avoiding accidental disconnection of the power cord due to operator inexperience or operational errors. This effectively prevents unexpected interruption of the dehumidification function, ensuring that the spectrometer's internal environment remains at a low humidity level, preventing damage to internal electronic components due to moisture, significantly reducing the equipment failure rate, extending the spectrometer's lifespan, and minimizing production downtime and maintenance costs caused by equipment damage. It can automatically detect desiccant humidity in real time, avoiding frequent manual checks, greatly saving labor costs, and improving the efficiency of pre-detection preparation. Furthermore, when the desiccant humidity exceeds the threshold, an audible and visual alarm will promptly sound, reminding operators to replace the desiccant, effectively preventing abnormal humidity levels in the detection environment due to desiccant failure, and ensuring... The online infrared spectrometer ensures the accuracy and reliability of product detection data from the flonicamid reactor by monitoring the reaction processes such as amidation and hydrolysis and determining the reaction endpoint. The automatic sliding and resetting structure of the anti-scattering mesh plate automatically protects the desiccant storage box after placement, effectively preventing desiccant spillage and ensuring its effectiveness. Furthermore, the anti-scattering mesh plate automatically opens when the desiccant humidity exceeds the standard, allowing staff to quickly remove the storage box for desiccant replacement, further enhancing operational convenience. The sample positioning frame and clamping spring plate accurately position and firmly clamp the sample support plate, ensuring the stability of the sample position during testing and preventing sample displacement from affecting the test results. The installation position of the position limiting rod can be adjusted according to different sample support plate sizes, achieving adaptability and limiting for different specifications of sample support plates, improving the equipment's versatility and adaptability, and meeting the diverse sample placement needs in the flonicamid production process.

[0029] Example 1: Please refer to Figures 1 to 4 As shown: This invention provides a detection device for detecting chemical products in a flonicamid reaction vessel, comprising a spectrometer body 1, a limiting mounting bracket 2, a guide connecting ring 3, a position limiting rod 4, a limiting structure, a limiting baffle 5, and a limiting electromagnet 6; the limiting mounting bracket 2 is fixedly connected to the rear end face of the spectrometer body 1; the guide connecting ring 3 is fixedly connected to the rear end face of the limiting mounting bracket 2; the position limiting rod 4 is slidably connected to the inner side of the guide connecting ring 3; the limiting structure is disposed on the outer side of the spectrometer body 1; the limiting baffle 5 is fixedly connected to the upper part of the position limiting rod 4; the limiting electromagnet 6 is fixedly connected to the upper part of the guide connecting ring 3; a dehumidifier is disposed inside the spectrometer body 1, and the control circuit of the dehumidifier is connected in series with the control circuit of the limiting electromagnet 6.

[0030] The limiting structure includes a front sealing cover 101 and a rear sealing cover 102; the front sealing cover 101 is hinged to the front side of the spectrometer body 1; and the rear sealing cover 102 is hinged to the rear side of the spectrometer body 1.

[0031] The limiting structure also includes a power cord socket 103 and a position limiting plate 104; the power cord socket 103 is located on the rear side of the spectrometer body 1; the position limiting plate 104 is fixedly connected to the rear end face of the spectrometer body 1.

[0032] The limiting structure also includes a limiting metal plate 501 and a second reset elastic member 502; the limiting metal plate 501 is fixedly connected to the lower end face of the limiting baffle 5; the upper end of the second reset elastic member 502 is fixedly connected to the lower part of the position limiting plate 104, and the lower end of the second reset elastic member 502 is fixedly connected to the upper part of the limiting baffle 5.

[0033] The specific usage and function of this embodiment are as follows: When detecting chemical products in the flupyradifurone reactor, insert the power cord into the power cord socket 103, first open the rear sealing cover 102 to check the humidity of the desiccant, then open the front sealing cover 101 and place the sample into the spectrometer body 1. When the dehumidifier is powered on, the limiting electromagnet 6 will be simultaneously powered on and generate magnetic force. At this time, the limiting electromagnet 6 will attract the limiting metal plate 501, causing the limiting metal plate 501 to drive the limiting baffle 5 and the position limiting rod 4 along the rear side of the limiting mounting bracket 2. The guide connecting ring 3 moves downward, simultaneously stretching the second reset elastic element 502. At this time, the position limiting rod 4 will block the outside of the power cord, limiting the power cord and preventing it from being unplugged. The position limiting plate 104 can limit the maximum movement distance of the position limiting rod 4. After the dehumidifier stops running, the limiting electromagnet 6 is de-energized and loses its magnetic force, and the limiting metal plate 501 is no longer attracted. Under the action of the restoring force of the second reset elastic element 502, the limiting baffle 5 drives the position limiting rod 4 to automatically reset, at which time the power cord can be unplugged.

Multiple guide mounting grooves 115 are provided, all fixedly connected to the upper part of the spectrometer body 1, and slidably connected to the anti-scattering mesh plate 112. The audible and visual alarm 121 is fixedly connected to the upper part of the spectrometer body 1, and its control circuit is connected in series with the control circuit of the positioning electromagnet 108.

[0039] The inspection structure also includes a positioning mounting plate 116 and a template positioning frame 117; the positioning mounting plate 116 is fixedly connected to the front side of the spectrometer body 1; the template positioning frame 117 is fixedly connected to the upper part of the positioning mounting plate 116.

[0040] The inspection structure also includes a clamping spring plate 118, a position limiting rod 119, and a sample support plate 120. Multiple clamping spring plates 118 are provided, and the multiple clamping spring plates 118 are respectively fixedly connected to the front and rear sides of the sample positioning frame 117.

The control circuit sends a signal to the audible and visual alarm 121 to remind staff to replace the desiccant in time, avoiding the inconvenience of manual inspection. At the same time, the positioning electromagnet 108 generates magnetic force to attract the positioning metal plate 111, causing the positioning metal plate 111 to drive the guide connecting sleeve 110 to slide, thereby driving the anti-scattering mesh plate 112 to open, making it easy to take out the desiccant storage box 106. When placing the sample, the sample support plate 120 is aligned with the sample positioning frame 117 on the upper part of the positioning mounting plate 116 and then pushed downward. The position limiting rod 119 can limit the position of the sample support plate 120. At the same time, according to the specific size of the sample support plate 120, the position limiting rod 119 can be screwed into the corresponding threaded hole to facilitate the limiting of sample support plates 120 of different sizes. The clamping spring plate 118 can clamp the sample support plate 120 to ensure the stability of the position during the sample detection process.
