Description

Technical Field

[0001] This application relates to the technical field of flame retardancy performance detection of petrochemical work clothes, and in particular to a flame retardancy performance detection system for petrochemical work clothes. Background Technique

[0002] At present, in high-risk industries such as petrochemical, natural gas extraction and refining, operators are often exposed to high temperatures, flames or flammable and explosive environments. Therefore, the flame retardancy performance of work clothes is crucial for ensuring personnel safety. According to the international standard ISO11612 and the national standard GB8965.1-2020 "Protective Clothing - Flame Retardant Clothing", work clothes in the petrochemical industry need to pass strict flame retardancy performance tests, including key indicators such as afterflame time, smoldering time, and damage length.

[0003] Common flame retardancy performance detection methods mainly include vertical burning test, 45-degree inclined burning test and limiting oxygen index test, etc. These methods all adopt standardized experimental environments, use specific combustion sources (such as open flames, thermal radiation) to test samples, and evaluate the flame retardancy performance based on the characteristics after combustion. For example, the Chinese patent with the publication number CN219915527U proposes a flame retardancy performance test device for clothing fabrics. This device adjusts the distance between the support plates by driving the threaded rod and the threaded sleeve with a motor, and cooperates with the second threaded rod to control the upper and lower clamping plates to clamp and fix the fabric; after adjusting the height of the test bench with a telescopic cylinder, the fabric is ignited by a lighter, and the gas supply pipe supplies gas to maintain combustion. At the same time, the powder pumping pump sprays fire extinguishing powder through the powder spraying head. Its core lies in accurately clamping the fabric through a mechanical structure and automatically controlling the combustion and fire extinguishing processes, so as to ensure the stability and accuracy of the test.

[0004] However, most of the current flame retardancy performance detection systems are based on standard laboratory environments and cannot simulate the complex and changeable working conditions in the petrochemical industry. Since work clothes need to be used repeatedly within a certain period of time, only theoretical data can be obtained under experimental conditions, and it is difficult to reflect the actual use situation. In addition, factors such as repeated cleaning, wear and oil pollution during daily use will cause the attenuation of flame retardancy performance, resulting in a deviation between the test results and the actual application, and it is impossible to accurately evaluate the service life and safety of work clothes in real workplaces. Summary of the Invention

[0005] This application provides a flame retardancy performance detection system for petrochemical work clothes. This detection system can simulate the complex and changeable use environment of petrochemical work clothes, and at the same time set different combustion modes to facilitate a more comprehensive evaluation of the flame retardancy performance of petrochemical work clothes.

[0006] The flame retardancy performance detection system for petrochemical work clothes provided by this application adopts the following technical solutions: A flame retardancy performance detection system for petrochemical work clothes, comprising: A base, on which an installation frame is fixedly provided. A housing is covered on the base, and a control panel is arranged on the housing; A simulation component, which includes an installation disc, a rolling roller, an elastic connecting piece and a driving piece. A work clothing sample is fixedly arranged on the installation disc. The installation disc is rotatably arranged on the installation frame. The elastic connecting piece is rotatably arranged on the installation frame. The rolling roller is arranged on the elastic connecting piece. The rolling roller is in movable abutment with the installation disc. The driving piece is arranged on the base. The driving piece is in transmission connection with the elastic connecting piece. The driving piece drives the elastic connecting piece to reciprocally swing on the installation frame, so that the rolling roller repeatedly rolls over the work clothing sample fixedly arranged on the installation disc; A combustion component, which includes a sliding frame and a spray gun for burning the work clothing sample. The sliding frame is fixedly arranged on the housing. A sliding seat is slidably arranged on the sliding frame. The spray gun is arranged on the sliding seat. The spray gun is directly opposite to the installation disc; A detection component, which includes a visual camera. The visual camera is arranged on the housing. The visual camera can detect the burning condition of the work clothing sample in real time.

[0007] By adopting the above technical scheme, the set simulation component can carry out dynamic mechanical loss (such as rolling and abrasion) on the work clothing sample, simulate the influence of factors such as long-term wearing, washing and oil pollution on the flame retardant performance, and make the test result closer to the actual use situation of the work clothing. Then, the spray gun and the sliding frame in the combustion component are used to accurately control the position and movement track of the combustion source, ensuring that the sample is subjected to a uniform and stable flame action. Different from the traditional fixed combustion test, this detection system can carry out dynamic mechanical loss on the work clothing sample according to the experimental requirements, making the test of the flame retardant performance of the work clothing more flexible and accurate, and providing a flame retardant performance evaluation closer to the actual use situation; At the same time, the set visual camera can record the combustion process of the sample in real time, including data such as flame propagation, damage morphology and afterflame time, realize automatic analysis, reduce human error, and improve the accuracy and reliability of the data.

[0008] Optionally, the combustion assembly further includes a mode switch, which includes a switching plate, a return spring and an electromagnet. A buffer tube is provided on the spray gun. One end of the buffer tube is provided with a flame outlet head, and an igniter and a mounting portion are provided on the flame outlet head. The igniter is electrically connected to the control panel. A receiving cavity is formed in the mounting portion. The switching plate is slidably disposed in the receiving cavity. A first ventilation hole and a second ventilation hole are respectively formed in the switching plate along its length direction. A plurality of groups of isolation valves are embedded in the second ventilation hole, and the plurality of groups of isolation valves are openable and closable in the second ventilation hole. The return spring is located at one end of the switching plate in the length direction, and the electromagnet is located at the other end of the switching plate. The return spring is disposed in the receiving cavity. One end of the return spring is fixedly connected to the inner wall of the receiving cavity, and the return spring is fixedly connected to one end of the switching plate. The electromagnet is fixed on the mounting portion, and the electromagnet is electrically connected to the control panel. The electromagnet can act on the switching plate. When the electromagnet is activated, the electromagnet can adsorb one end of the switching plate, and the flame outlet head communicates with the buffer tube through the second ventilation hole; when the electromagnet is turned off, the flame outlet head communicates with the buffer tube through the first ventilation hole.

[0009] By adopting the above technical solution, by using the adsorption or release effect of the provided electromagnet, the switching plate is controlled to slide in the receiving cavity, so that the first ventilation hole and the second ventilation hole are selectively communicated with the buffer tube. At the same time, a plurality of groups of isolation valves are embedded in the second ventilation hole, and these valves can control the way of introducing the combustion air flow, thereby adjusting the combustion mode of the spray gun. That is, in the state of the electromagnet being powered on or off, the spray gun can be respectively connected to different air flow channels, so as to simulate different types of combustion scenarios (such as open fire, slow combustion, deflagration, etc.), so as to adapt to different application environments of work clothes with different standards of flame retardant tests. While enhancing the versatility of the detection system, the setting of the electromagnet and the switching plate makes the combustion mode more controllable, reduces manual intervention, and improves the experimental efficiency and test consistency.

[0010] Optionally, the simulation component further includes a medium coating member, which includes a liquid storage tank, a liquid injection pump, and a liquid storage box. The liquid storage tank is fixedly arranged on the base, the liquid storage box is fixedly arranged on the mounting rack, the liquid injection pump is arranged on the bottom plate, the suction end of the liquid injection pump is communicated with the liquid storage tank, the liquid discharge end of the liquid injection pump is communicated with the liquid storage box, the liquid storage box is filled with an environmental liquid medium, a liquid outlet is arranged on the liquid storage box and is communicated with the liquid storage box, a ball is arranged on the liquid outlet, the ball is rotatably embedded in the liquid outlet, when the driving member can drive the elastic connecting member to reciprocally swing on the mounting rack, the rolling roller is selectively and movably abutted against the mounting disc and the liquid storage box, and when the rolling roller is movably abutted against the liquid storage box, the rolling roller slides over the ball, so as to coat the environmental liquid medium in the liquid storage box on the rolling roller through the ball.

[0011] By adopting the above technical solution, the medium coating member is used to simulate the soiling situation of the work clothes in a complex environment, so as to improve the authenticity of the test. Considering that in reality, the work clothes of petrochemical enterprises will be contaminated by oil stains, chemical solvents, moisture, etc. during use, and these factors may affect the flame retardancy performance. The traditional flame retardancy test is usually carried out on a clean and pollution-free sample, and the traditional flame retardancy detection usually only focuses on the action of the flame, without considering the change of the flame retardancy performance of the work clothes caused by mechanical damages such as friction and compression during use, resulting in a deviation between the experimental data and the actual application. However, this detection system combines the rolling roller, so that the work clothes sample undergoes a certain degree of mechanical loss before the combustion test, and the environmental liquid medium is synchronously coated during the rolling process, ensuring that the pollutants are in full contact with the fibers, thus more realistically simulating the aging process of the work clothes and improving the ability to evaluate the influence of environmental factors on the flame retardancy performance, providing a scientific basis for the replacement cycle of safety protective clothing.

[0012] Optionally, the rolling roller includes a rotating shaft, a rolling sleeve, and a positioning ring. One end of the rotating shaft is rotatably arranged on the elastic connecting member. There are two groups of elastic connecting members, and the two groups of elastic connecting members are symmetrically arranged along the diameter direction of the mounting disc. The rotating shaft is erected on the mounting disc through the two groups of elastic connecting members. The rolling sleeve is coaxially sleeved on the rotating shaft. External threads are arranged at both ends of the rotating shaft. The positioning ring is arranged at one end of the rotating shaft and is threadedly connected with the rotating shaft. There are two groups of positioning rings, and the two groups of positioning rings fix the rolling sleeve on the rotating shaft.

[0013] By adopting the above technical solution, the combination of the rotating shaft, the rolling sleeve and the positioning ring enables the rolling roller to rotate freely, ensuring uniform mechanical wear on the work clothing specimen and improving the authenticity of simulated wear. Through the threaded connection between the positioning ring and the rotating shaft, it is ensured that the rolling sleeve can be reliably fixed on the rotating shaft without loosening easily, improving the stability and service life of the rolling roller. At the same time, such a setting also facilitates the disassembly, replacement and maintenance of the rolling roller. Different rolling sleeves with different materials or surface textures can be replaced according to different experimental requirements to adapt to different wear simulation tests and improve the adaptability of the test system. For example, rolling sleeves with different hardness or surface roughness can be used to simulate different types of physical wear (such as grit friction, wear caused by long-term wearing, etc.), making the test more accurate.

[0014] Optionally, the elastic connecting member includes a connecting shaft, a connecting arm and an elastic telescopic rod. The connecting shaft is rotatably inserted through the mounting bracket. The connecting arm is fixedly arranged at one end of the connecting shaft. There are two groups of the connecting arms, and the two groups of connecting arms are symmetrically arranged along the length direction of the connecting shaft. The fixed end of the elastic telescopic rod is fixedly arranged on the connecting arm. A connecting seat is arranged on the telescopic end of the elastic telescopic rod. One end of the rotating shaft is rotatably connected to the connecting seat. There are two groups of the elastic telescopic rods, and the two groups of elastic telescopic rods are symmetrically arranged along the width direction of the connecting arm.

[0015] By adopting the above technical solution, the elastic connecting member composed of the elastic telescopic rod, the connecting shaft and the connecting arm can dynamically adjust the pressure of the rolling roller, and can make small-angle adjustments during the rolling process to adapt to work clothing specimens of different thicknesses, softnesses and materials, ensuring that the rolling process is uniform and stable. At the same time, the elastic telescopic rod can provide appropriate buffering during the rolling process, and the rolling roller will not cause a violent impact when contacting the work clothing specimen, thereby reducing abnormal damage to the surface of the specimen and ensuring that the test only evaluates the natural wear of the material itself. This structure effectively reduces the test error and improves the scientificity of the flame retardant performance evaluation.

[0016] Optionally, the detection component further includes a temperature sensor, and the temperature sensor is embedded on the surface of the mounting disk facing away from the rotating frame, and the temperature sensor is electrically connected to the control panel.

[0017] By adopting the above technical solution, a temperature sensor is embedded on the mounting disk to monitor the temperature change of the work clothing specimen in real time, providing quantitative data for the flame retardant performance. Combining with the data of the visual camera, multi-dimensional analysis of the combustion process is realized, enhancing the scientificity of the experiment and improving the accuracy of the test.

[0018] Optionally, a rotating frame is fixedly installed on the mounting frame. One end of the mounting disc is fixedly provided with a rotating part, and the rotating part is rotatably connected to the rotating frame. The mounting disc is rotatably arranged on the rotating frame through the rotating part, and the mounting disc is inclined on the rotating frame. An annular disc cover is arranged on the mounting disc. One end of the mounting disc where the rotating part is provided is fixedly provided with a positioning outer edge. A first stepped surface is formed between the positioning outer edge and the mounting disc. A diameter-expanding part is arranged on the inner wall of the annular disc cover. A second stepped surface is formed between the diameter-expanding part and the inner wall of the annular disc cover. The annular disc cover is threadedly connected to the positioning outer edge. When the work clothing sample is laid on the mounting disc, the annular disc cover is buckled on the mounting disc, and the first stepped surface abuts against the second stepped surface, thereby fixing the work clothing sample on the mounting disc.

[0019] By adopting the above technical solution, the combined design of the annular disc cover and the positioning outer edge is adopted to ensure the stable fixation of the work clothing sample during the test, avoid displacement caused by combustion or mechanical wear, which affects the test results. At the same time, the threaded connection method realizes the convenience of sample replacement and improves the operability of the experiment.

[0020] Optionally, the driving member includes a motor, a turntable and a lever. A transmission rod is arranged between two groups of the connecting arms. One end of the transmission rod is fixedly connected to a group of adjacent connecting arms. The motor is fixed on the mounting frame. The motor is electrically connected to the control panel. The turntable is fixedly arranged on the output end of the motor. One end of the lever is rotatably connected to the transmission rod, and the other end of the lever is rotatably connected to the turntable. And the end of the lever connected to the turntable is far from the rotation center of the turntable.

[0021] By adopting the above technical solution, the transmission structure of the motor, the turntable and the lever is adopted to ensure the stable operation of the rolling mechanism and improve the reliability of the mechanical wear simulation.

[0022] Optionally, a turning member is arranged on the rotating part. The turning member includes an end face gear, a turning rod and a cam. The end face gear is fixedly arranged on the rotating part. The turning rod is rotatably arranged on the rotating frame, and a torsion spring is arranged between the turning rod and the rotating frame. The cam is fixedly arranged on the connecting shaft. One end of the turning rod is in movable contact with the cam, and the other end of the turning rod is in plug-in fit with the end face gear. When the connecting arm reciprocally swings on the mounting frame, the turning rod cyclically turns the end face gear to rotate, so that the mounting disc rotates on the rotating frame.

[0023] By adopting the above technical solution, by using the combination of the end face gear, the turning rod and the cam arranged, the mounting disc can rotate synchronously during the rolling process, ensuring that the work clothing sample is subject to more uniform wear and improving the reliability of the test.

[0024] Optionally, it further includes a filtering component, which includes an exhaust fan, an exhaust pipe and a filter box. An exhaust port is provided on the housing, the exhaust fan is fixedly arranged in the exhaust port, the filter box is arranged on one side of the housing, one end of the exhaust pipe is communicated with the exhaust port, the other end of the exhaust pipe extends into the filter box, and the filter box can filter the flue gas generated by the flame retardant performance detection of petrochemical work clothes.

[0025] By adopting the above technical solution, with the exhaust fan, the exhaust pipe and the filter box, it can effectively filter the harmful flue gas generated during the combustion test, reduce the environmental pollution of the experiment, and improve the safety of the experiment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The set simulation component can perform dynamic mechanical losses (such as rolling and abrasion) on the work clothes sample, simulating the influence of factors such as long-term wearing, washing, and oil pollution on the flame retardant performance, making the test results closer to the actual use situation of the work clothes. Then, the spray gun and the sliding frame in the combustion component are used to accurately control the position and movement trajectory of the combustion source, ensuring that the sample is subjected to a uniform and stable flame action. Different from the traditional fixed combustion test, this detection system can perform dynamic mechanical losses on the work clothes sample according to the experimental requirements, making the test of the flame retardant performance of the work clothes more flexible and accurate, and providing a flame retardant performance evaluation closer to the actual use situation. At the same time, the set visual camera can record the combustion process of the sample in real time, including data such as flame propagation, damage morphology, and afterflame time, realizing automatic analysis, reducing human error, and improving the accuracy and reliability of the data; 2. The set medium coating part is used to simulate the pollution situation of the work clothes in a complex environment, improving the authenticity of the test. Considering that in reality, petrochemical work clothes will be polluted by oil, chemical solvents, moisture, etc. during use, and these factors may affect the flame retardant performance. Traditional flame retardant tests are usually carried out on clean and pollution-free samples, and traditional flame retardant detections usually only focus on the flame action, without considering the change of flame retardant performance caused by mechanical damage such as friction and compression during the use of work clothes, resulting in a deviation between the experimental data and the actual application. And this detection system combines the rolling roller to make the work clothes sample experience a certain degree of mechanical loss before the combustion test, and synchronously coat the environmental liquid medium during the rolling process to ensure full contact between the pollutant and the fiber, thus more realistically simulating the aging process of the work clothes and improving the ability to evaluate the influence of environmental factors on the flame retardant performance, providing a scientific basis for the replacement cycle of work clothes; 3. By utilizing the adsorption or release effect of the set electromagnet, the switching plate is controlled to slide within the accommodating cavity, enabling the first ventilation hole and the second ventilation hole to selectively communicate with the buffer tube. Meanwhile, multiple groups of isolation valves are embedded in the second ventilation hole, and these valves can control the way of introducing the combustion airflow, thereby adjusting the combustion mode of the spray gun. That is, in the state of the electromagnet being powered on or off, the spray gun can be connected to different airflow channels respectively, so as to simulate different types of combustion scenarios (such as open fire, slow combustion, deflagration, etc.). In this way, different standard flame retardancy tests can be carried out to adapt to different application environments of work clothes, enhancing the versatility of the detection system. At the same time, the setting of the electromagnet and the switching plate makes the combustion mode more controllable, reduces manual intervention, and improves the experimental efficiency and test consistency.

A spline is fixedly provided at the end of the turning rod 372 away from the cam 373, and the spline can be inserted and matched with the end face gear 371.

[0048] The driving member 34 includes a motor 341, a turntable 342 and a lever 343. The motor 341 is fixed on the mounting frame 11. The motor 341 is electrically connected to the control panel 21. The turntable 342 is fixed on the output end of the motor 341. One end of the lever 343 is rotatably connected to the transmission rod 335, and the other end of the lever 343 is rotatably connected to the turntable 342, and the end of the lever 343 connected to the turntable 342 is far from the rotation center of the turntable 342.

[0049] Refer to Figure 5, in the embodiment of the present application, the medium coating member 35 includes a liquid storage tank 351, a liquid injection pump 352, a liquid storage box 353, and balls 354. The liquid storage tank 351 is fixedly arranged on the base 1. The liquid storage tank 351 is located on one side of the mounting frame 11 and below the combustion assembly 4. The liquid storage box 353 is fixedly mounted between two sets of support plates 111. The liquid storage box 353 is located below the mounting plate 31. The liquid injection pump 352 is fixedly arranged on the bottom plate. The liquid injection pump 352 is electrically connected to the control panel 21. The suction end of the liquid injection pump 352 is communicated with the liquid storage tank 351, and the liquid discharge end of the liquid injection pump 352 is communicated with the liquid storage box 353. The liquid storage tank 351 stores an environmental liquid medium, and the liquid storage box 353 is filled with the environmental liquid medium.

[0050] In this embodiment, the environmental liquid medium can be set as crude oil. Of course, in other embodiments of the present application, the environmental liquid medium can also be set as other liquids that appear in the petrochemical working environment and may affect the flame retardant performance of work clothes, such as diesel oil, strong acid and strong alkali solutions, etc.

[0051] One side of the liquid storage box 353 is flush with the side of the support plate 111. The support plate 111 is set as a rectangular plate, and the support plate 111 is provided with a chamfer on the side close to the mounting plate 31. The chamfered edge is flush with the side of the mounting plate 31 facing away from the rotating frame 12. A plurality of liquid outlet ports 3531 are arranged on the side of the liquid storage box 353 close to the side of the support plate 111. The plurality of liquid outlet ports 3531 are evenly arranged on the liquid storage box 353. The liquid outlet ports 3531 are communicated with the liquid storage box 353. The balls 354 are rotatably embedded in the liquid outlet ports 3531, and a part of the balls 354 protrudes from the surface of the liquid storage box 353. When the driving member 34 can drive the elastic connecting member 33 to reciprocate and swing on the mounting frame 11, the rolling roller 32 is in movable contact with the mounting plate 31 and the liquid storage box 353 alternately. When the rolling roller 32 is in movable contact with the liquid storage box 353, the rolling roller 32 slides over the balls 354, so as to coat the environmental liquid medium in the liquid storage box 353 on the rolling roller 32 through the balls 354.

[0052] By accurately controlling the flow rate of the coating medium by the liquid injection pump 352, the pollution degree can be adjusted according to the experimental requirements, such as simulating different scenarios of slight pollution (a small amount of oil stain) or heavy pollution (chemical immersion) of work clothes, making the experiment more flexible; at the same time, the ball 354 coating method is adopted to ensure that the pollutants are evenly distributed on the surface of the specimen, improving the consistency and repeatability of the experiment and avoiding the errors that may be brought by traditional manual coating.

[0053] In more detail, the work clothes sample is laid on the mounting plate 31, the annular plate cover 36 is buckled on the mounting plate 31, and the annular plate cover 36 is tightened so that the first step surface and the second step surface are pressed against each other, thereby fixing the work clothes sample on the mounting plate 31, and the motor 341 is started to drive the turntable 342 to rotate, and the turntable 342 drives the connecting arm 332 to reciprocate on the mounting frame 11 through the lever 343, and the rolling roller 32 is cyclically rolled between the mounting plate 31 and the liquid storage box 353. In this process, when the rolling roller 32 is pressed on the liquid storage box 353, the rolling roller 32 will press down the ball 354 and pass over the ball 354, and the ball 354 will apply the liquid medium in the liquid storage box 353 to the rolling roller 32, so that the rolling roller 32 that has been stained with the liquid medium will apply the liquid medium to the work clothes sample. At the same time, the rolling roller 32 will repeatedly roll the work clothes sample to simulate the friction loss of the work clothes in the actual application process. After a certain frequency of rolling, the flame will be directly burned or deflagrated. In this way, the flame retardant performance of the work clothes and the actual use time of the work clothes can be comprehensively evaluated.

[0054] Reference Figure 5 , Figure 6 and Figure 7 In the embodiment of the present application, the combustion assembly 4 includes a sliding frame 41, a sliding seat 43, a spray gun 42, a sliding member and a mode switching member 44. The sliding frame 41 is fixed on the shell 2, and a sliding rail is fixed on the sliding frame 41. A slider is fixed on the sliding seat 43. The slider is slidably connected to the sliding rail. The sliding seat 43 is slidably set on the sliding frame 41 through the sliding rail. The spray gun 42 is fixed on the sliding seat 43. The spray gun 42 is facing the side of the mounting plate 31 away from the rotating frame 12. A gas storage tank for providing fuel to the spray gun 42 is installed on the outside of the shell 2. Methane gas is stored in the gas storage tank. The sliding member can be set as a hydraulic cylinder. The sliding frame 41 is fixed on the side of the sliding frame 41 away from the spray gun 42. The telescopic end of the sliding member is fixedly connected to the sliding seat 43, and the sliding member can drive the sliding seat 43 to slide back and forth on the sliding frame 41.

[0055] The mode switching member 44 includes a switching plate 441, a return spring 442, and an electromagnet 443. A buffer tube 421 is arranged on the spray gun 42. The diameter of the buffer tube 421 is larger than the nozzle diameter of the spray gun 42. A flame head 422 is arranged at one end of the buffer tube 421 away from the spray gun 42. An igniter 423 and a mounting portion 424 are respectively arranged on the flame head 422. The igniter 423 is electrically connected to the control panel 21. In the present embodiment, the mounting portion 424 is arranged as a rectangular block. An accommodating cavity 4241 is provided in the mounting portion 424. The switching plate 441 is slidably arranged in the accommodating cavity 4241. A first air vent 4411 and a second air vent 4412 are respectively opened on the switching plate 441 along its own length direction.

[0056] A plurality of isolation valves 444 are embedded in the second ventilation hole 4412, and the plurality of isolation valves 444 are arranged to be openable and closable in the second ventilation hole 4412. The isolation valves 444 are arranged in a petal shape and can be made of heat-resistant metal. The plurality of isolation valves 444 are circumferentially distributed in the second ventilation hole 4412, and two adjacent isolation valves 444 are in contact with each other to block the second ventilation hole 4412. When the methane in the buffer pipe 421 reaches a certain pressure, the isolation valves 444 will be pushed open, so that the flame outlet 422 is communicated with the buffer pipe 421. At this time, methane passes through the igniter 423 to form deflagration, which then acts on the work clothing sample.

[0057] The return spring 442 is located at one end of the switching plate 441 in the length direction. The return spring 442 is arranged in the accommodation cavity 4241. One end of the return spring 442 is fixedly connected to the inner wall of the accommodation cavity 4241, and the return spring 442 is fixedly connected to one end of the switching plate 441. The electromagnet 443 is arranged at the end of the switching plate 441 away from the return spring 442, and the switching plate 441 is made of a metal material. The switching plate 441 can be attracted by the electromagnet 443. The electromagnet 443 is fixedly installed on the installation part 424, and the electromagnet 443 is electrically connected to the control panel 21.

[0058] More specifically, in the initial state, the electromagnet 443 is not powered on, and the return spring 442 is in a tightened state. At this time, the buffer pipe 421 is communicated with the flame outlet 422 through the first ventilation hole 4411. Then, at this time, the spray gun 42 is just an ordinary flame spraying and burning; the flame outlet 422 is communicated with the buffer pipe 421 through the second ventilation hole 4412. Due to the setting of the isolation valves 444, the buffer pipe 421 will only conduct after storing a certain amount of methane, so as to form deflagration.

[0059] In traditional flame retardant detection, the test samples are only burned by direct open fire. However, in petrochemical scenarios, in addition to open fire combustion, there are often deflagration accidents caused by gas leakage. In the deflagration scenario, simple flame retardant detection is not enough to evaluate the flame retardant performance of petrochemical work clothing. Because in addition to generating high temperature during deflagration, there will also be high temperature gas jets. These gas jets are different from open fire combustion. They will act on the work clothing and penetrate into the work clothing to act on the skin faster. And most of the gases in petrochemical scenarios are corrosive. In this way, by setting the mode switching member 44 and the medium coating member 35, different types of combustion scenarios (such as open fire, slow combustion, deflagration, etc.) are simulated, so as to perform different standard flame retardant tests to adapt to different application environments of work clothing, enhance the versatility of the detection system, and ensure a more comprehensive evaluation of the flame retardant performance of petrochemical work clothing.

[0060] Refer to Figure 5, in the embodiment of the present application, the filtering component 6 includes an exhaust fan 61, an exhaust pipe 62, and a filtering box 63. An exhaust port 22 is formed on the housing 2. The exhaust fan 61 is fixedly arranged in the exhaust port 22. The exhaust fan is electrically connected to the control panel 21. The filtering box 63 is arranged on one side of the housing 2. One end of the exhaust pipe 62 is communicated with the exhaust port 22, and the other end of the exhaust pipe 62 extends into the filtering box 63. Water is injected into the filtering box 63, and the end of the exhaust pipe 62 extending into the filtering box 63 is immersed in the water. The filtering box 63 can filter the smoke generated by the flame retardant performance detection of petrochemical work clothes.

[0061] Referring to Figure 5 , the detection component 5 includes a visual camera 51 and a temperature sensor 52. The visual camera 51 is arranged on the housing 2. The visual camera 51 is located above the mounting plate 31. The visual camera 51 is electrically connected to the control panel 21. The visual camera 51 can capture the burning situation of the work clothes sample in real time, including the size of the burned area, the damaged situation of the sample after the burning stops, etc. The temperature sensor 52 is fixedly embedded on the side of the mounting plate 31 facing away from the rotating frame 12, and the temperature sensor 52 is located at the center of the mounting plate 31. The temperature sensor 52 is electrically connected to the control panel 21.

[0062] The implementation principle of the petrochemical work clothes flame retardant performance detection system in the embodiment of the present application is as follows: The petrochemical work clothes to be detected are sampled and fixed on the mounting plate 31. Then, the rolling roller 32 is started to repeatedly roll the sample to simulate the wear of the work clothes in daily use. At the same time, during the rolling process of the rolling roller 32, the rolling roller 32 will slide across the liquid storage box 353, so that the rolling roller 32 is coated with a liquid medium, thereby simulating that the work clothes are contaminated with a flammable liquid medium or a corrosive liquid medium in daily use, resulting in the attenuation of the flame retardancy of the work clothes. After the rolling roller 32 grinds the sample on the mounting plate 31 a certain number of times, the control sliding member drives the spray gun 42 to extend out to burn the sample. The visual camera 51 monitors the burning situation of the sample in real time, and the temperature sensor 52 can detect the temperature change on the back of the sample when the sample is burned, so as to comprehensively detect the flame retardant performance of the work clothes and evaluate the reasonable service life of the work clothes in daily use.

[0063] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
