Description

Technical Field

[0001] The present invention relates to the technical field of testing devices, in particular to a sealing testing device and method for sealing fireproof organic filler. Background Art

[0002] Sealing and fireproof organic fillers are widely used in the construction, power, and chemical industries, for example, sealing and fireproofing cable holes and building gaps. In these applications, sealing and fireproof organic fillers must not only provide excellent sealing properties to prevent gas and liquid leakage, but also effectively prevent the spread of flames, heat transfer, and smoke in the event of a fire, thereby buying time for evacuation and firefighting.

[0003] Currently, there are many problems with testing fire-resistant organic sealants. For one thing, existing sealing performance testing devices and methods are unable to accurately simulate the complex environments found in actual working conditions, such as the combined effects of temperature, pressure, and vibration.

[0004] In a building fire, the ambient temperature will rise sharply in a short period of time, which may be accompanied by local pressure changes caused by combustion and vibrations caused by deformation of the building structure. Traditional testing equipment cannot fully and accurately simulate these factors, resulting in a large deviation between the test results and the actual use effect.

[0005] On the other hand, most tests for the fire resistance of sealed fireproof organic fillers are independent of their sealing performance, failing to directly reflect the fireproofing effectiveness of the filler in a sealed state. Furthermore, existing testing methods lack effective monitoring of the dynamic changes in the filler's sealing performance during a fire, making it difficult to assess its overall performance throughout the fire cycle.

[0006] In addition, the existing testing devices have a low degree of automation, the operation process is cumbersome, the testing efficiency is low, and the accuracy and repeatability of the test results are greatly affected by human factors.

[0007] Therefore, it is of great practical significance to develop a testing device and method that can comprehensively and accurately test the sealing performance of sealed fireproof organic fillers while taking into account the fire performance test, and is easy to operate and highly automated.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 , the present invention provides a technical solution: A sealing test device for sealing fireproof organic filler, comprising a test bench 1, a PLC control box 2 is fixedly installed at the front edge of the upper end surface of the test bench 1, for controlling the operation process of the entire device, and then four support rods 3 are fixedly installed at the middle position of the left side of the upper end surface of the test bench 1, and a flame spraying device 4 is fixedly installed on the outer circumferential surface of the upper end of the four support rods 3. Figure 1 As shown, a feed pipe 5 is fixedly installed on the left side of the flame spraying device 4, and a material box 6 is fixedly installed on the other end of the feed pipe 5 away from the flame spraying device 4. The material box 6 is located below the flame spraying device 4, as shown in FIG. Figure 1 shown.

[0027] Furthermore, a flame hood 7 is fixedly installed on the right side of the flame spraying device 4 , and the flame hood 7 is used to be fixedly connected to the subsequent test box 11 , so that the sprayed flame can be inside the test box 11 .

[0028] During use, the tester first sets the test parameters through the PLC control box 2, and then starts the device. The organic filler in the material box 6 is fed into the flame spray device 4 through the feeding pipe 5. Under the action of the flame spray device 4, the organic filler is ignited and generates a flame. The flame enters the test box 11 under the guidance of the flame spray hood 7 to test the sealing and fire resistance of the test sample 27.

[0029] The upper end surface of the test bench 1 is fixedly installed with an oblique support rod 8 in a transverse symmetrical manner. The upper end of the oblique support rod 8 is fixedly installed with a convex chute 9, and a chute rod 10 is slidably installed inside the convex chute 9. Figure 7 shown.

[0030] A test box 11 is fixedly mounted on the upper end surface of the slide rod 10 . The test box 11 can be disassembled and replaced through the above structure, so that the operator can inspect and maintain the test box 11 after completing the operation.

[0031] It should be noted that the material used for the test box 11 is a high-temperature resistant material, and the subsequent materials inside it also use high-temperature resistant materials to avoid being burned.

[0032] An upper cavity 12 and a lower cavity 13 are respectively provided on both sides of the test box 11. Figure 6 shown.

[0033] Then, a refrigerator 14 is fixedly installed on the upper right side of the test box 11, and cooling pipes 15 are fixedly installed at both ends of the refrigerator 14. The cooling pipes 15 are installed inside the upper cavity groove 12. A heater 16 is fixedly installed on the lower right side of the test box 11, and heating pipes 17 are fixedly installed at the front and rear ends of the heater 16. The heating pipes 17 are located inside the lower cavity groove 13. Figure 6 shown.

[0034] During use, Testers can precisely control the temperature inside the test box 11 through the refrigerator 14 and the heater 16. The refrigerator 14 releases cold air to the upper cavity groove 12 through the cooling tube 15, effectively reducing the temperature of the test box 11, while the heater 16 releases hot air to the lower cavity groove 13 through the heating tube 17, increasing the temperature of the test box 11. This ensures that the test box 11 is at a suitable test temperature and can simulate different temperature environments to test the sealing and fire resistance of organic fillers under different temperature conditions, thereby ensuring the accuracy and comprehensiveness of the test results. At the same time, the power of the refrigerator 14 and the heater 16 can be adjusted, and testers can flexibly set them according to actual needs, further improving the flexibility and practicality of the test.

[0035] A sealing cover 18 is rotatably mounted on the upper end surface of the test box 11 using a hinge. The sealing cover 18 is used to seal the top opening of the test box 11 to prevent flames from being ejected during operation.

[0036] A connecting ring 19 is fixedly mounted in the middle of the right side of the test box 11 , and a rotating ring 21 is rotatably and slidably mounted inside the connecting ring 19 .

[0037] A vibrator 20 is fixedly mounted on the right edge of the upper end of the test bench 1. The upper left side of the vibrator 20 is in threaded rotation connection with the rotating ring 21. Figure 4 shown.

[0038] The rotating ring 21 and the connecting ring 19 can be assembled together through the thread, so that they can be assembled after subsequent operations.

[0039] During use, the tester can start the vibrator 20 so that the output end of the vibrator 20 drives the rotating ring 21 to vibrate; since the rotating ring 21 and the connecting ring 19 are threadedly connected, the rotating ring 21 will slide while threadedly rotating inside the connecting ring 19, and as the rotating ring 21 rotates, the rotating ring 21 will gradually move toward the inside of the connecting ring 19 until the rotating ring 21 and the connecting ring 19 are completely locked. Therefore, the vibration frequency of the rotating ring 21 will be transmitted to the connecting ring 19, vibrating the test box 11. During the operation, as the vibrator 20 continues to work, the vibration of the test box 11 is not only uniform but also controllable, which helps to simulate various vibration environments that may be encountered in actual applications, thereby evaluating the sealing performance of the fire-retardant organic filler.

[0040] Since the vibration frequency and amplitude of the vibrator 20 are adjustable, the tester can flexibly set them according to actual needs to simulate different vibration environments, thereby further improving the flexibility and practicality of the test.

[0041] A temperature sensor 22 is fixedly installed inside the test box 11, and a servo motor 23 is fixedly installed outside the lower end of the test box 11 and inside the slide rod 10. A reciprocating screw 24 is fixedly installed on the output shaft of the servo motor 23. The reciprocating screw 24 is located inside the test box 11, and a connecting slide 25 is threadedly installed on the circumferential surface of the reciprocating screw 24. A U-shaped cavity 26 is fixedly installed inside the connecting slides 25 on both sides. A test sample 27 is slidably installed inside the U-shaped cavity 26. Figure 6 shown.

[0042] During the test, temperature sensor 22 monitors temperature changes within test chamber 11 in real time, ensuring the test environment remains within the set temperature range. This is crucial for evaluating the sealing performance of fire-retardant organic fillers under varying temperature conditions. Activation of servo motor 23 rotates reciprocating screw 24. Because reciprocating screw 24 is threadedly connected to connecting slide 25, connecting slide 25 reciprocates on reciprocating screw 24 as it rotates.

[0043] The design of the U-shaped cavity 26 not only provides installation space for the test sample 27, but also ensures the stability of the test sample 27 during the reciprocating sliding process, avoiding the accuracy of the test results affected by shaking or offset. At the same time, by adjusting the speed of the servo motor 23 and the pitch of the reciprocating screw 24, the reciprocating movement speed and stroke of the test sample 27 can be flexibly controlled to meet different testing requirements. After installation and subsequent completion of the work, the operator can slide the test sample 27 out of the interior of the test box 11, so that the operator can easily install and remove the test sample 27.

[0044] A first connecting pipe 28 is fixedly installed at the front end of the test box 11. A pressure regulating valve 29 is fixedly installed at the upper portion of the front end of the first connecting pipe 28. A gas flow meter 30 is fixedly installed at the upper end of the pressure regulating valve 29. A temperature sensor 31 is fixedly installed at the upper end of the gas flow meter 30. A second connecting pipe 32 is fixedly installed at the rear end face of the test box 11. A gas leakage sensor 33 is fixedly installed at the upper portion of the rear end of the second connecting pipe 32.

[0045] During use, the temperature sensor 31 monitors the temperature of the gas flowing into the test chamber 11 in real time, ensuring that the gas temperature during the test meets the preset standard. This is also important for evaluating the sealing performance of the fire-retardant organic filler at different temperatures. The gas flowmeter 30 precisely controls the gas flow into the test chamber 11 to ensure the stability and repeatability of the test conditions. By adjusting the pressure regulating valve 29, operators can flexibly adjust the gas pressure inside the test chamber 11 to simulate different working environments, further broadening the application range of the test device. After the test is completed, the gas leakage sensor 33 plays a key role, sensitively capturing any minor gas leaks, thereby accurately evaluating whether the fire-retardant organic filler's sealing performance meets the standard. This series of sophisticated design and control measures together constitute the core competitiveness of this sealing test device.

[0046] Working principle: Step 1: Open the sealing plate cover 8 and start the servo motor 23. The output shaft of the servo motor 23 rotates the reciprocating screw 24, thereby allowing the connecting slide 25 to slide out of the interior of the test box 11 with the U-shaped cavity 26. At this time, the test sample 27 is slidably installed in the U-shaped cavity 26. Step 2: The servo motor 23 operates in reverse, allowing the test sample 27 to slide into the interior of the test chamber 11. At this time, the various test parameters required by the test are set through the PLC control box 2 according to the situation, including the initial temperature, pressure, vibration frequency and amplitude, fire source intensity, and test time; Step 3: Start the heater 16 and the refrigerator 14 to adjust the internal temperature of the test box 11 to the set initial temperature, and at the same time adjust the gas pressure in the air inlet pipe to the set value through the pressure regulating valve 29; Step 4: Turn on the vibrator 20 to vibrate the sealed chamber according to the set vibration frequency and amplitude; Step 5: Introduce gas into the test box 11 through the gas flow meter 30, and simultaneously monitor the data of the leaking gas sensor 33, recording the concentration and flow of the leaking gas, so as to evaluate the sealing performance of the sealed fireproof organic filler under the simulated working conditions; Step 6: After the sealing performance test is completed, the pressure and temperature in the sealed chamber are kept constant, and the flame spray device 4 is started to heat the sealed chamber according to the set fire source intensity to simulate a fire scene. The data of each temperature sensor 31 in the test box 11 is monitored in real time, and the temperature change curve is recorded to evaluate the fireproof performance of the sealed fireproof organic filler under the fire environment and the dynamic changes of the sealing performance; Step 7: The data acquisition system transmits all collected data to the computer, and the data processing software analyzes and processes the data, and generates a detailed test report based on the data analysis results.
