Description

Technical Field

[0001] This utility model relates to the field of basalt fiber cotton performance testing technology, and more specifically, to a device for testing the filtration performance of basalt microfiber cotton. Background Technology

[0002] Basalt microfiber cotton is an ultra-fine inorganic fiber material made from natural basalt through high-temperature melting, centrifugal fiber forming, or filament drawing processes. It possesses a unique combination of properties. With its lightweight, wide-temperature-range stability, and green biodegradability, basalt microfiber cotton is rapidly penetrating from building insulation materials into high-tech fields such as aerospace, military, and high-end transportation equipment. As the demonstration effect of benchmark applications such as Chang'e 6 expands and the preparation technology continues to be optimized, its market potential in the context of carbon neutrality will be further released. Therefore, basalt microfiber cotton needs to be tested for its filtration performance before leaving the factory to maintain product quality.

[0003] Common basalt microfiber cotton filtration performance testing devices can only test the performance of basalt fiber cotton, but lack the function of adaptively replacing the test paper. In this type of testing process, test paper needs to be placed under the basalt fiber cotton. This design allows unfiltered impurities to fall onto the test paper, making it easier to judge the filtration effect. However, each time a gas containing different types of impurities is tested, those unfiltered impurities of different types fall onto the same test paper. This situation makes it difficult to accurately distinguish and judge the differences in the filtration effect of basalt fiber cotton for different substances, ultimately leading to a decrease in filtration efficiency assessment and inaccurate test results.

[0004] In summary, to improve filtration efficiency and the accuracy of detection results, it is necessary to address the issue of the inability to adaptively replace the detection paper, so that the detection paper can be adaptively replaced according to different gases containing different types of impurities. Utility Model Content

[0005] The problem to be solved by the basalt microfiber cotton filtration performance testing device provided by this utility model is: the inability to adaptively replace the test paper, so that when testing gases containing different types of impurities, the test paper can be adaptively replaced according to different gases.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a testing box, with an unwinding box fixedly connected to the right side of the testing box, a roll-changing door movably connected to the front of the unwinding box, a rewinding box fixedly connected to the left side of the testing box, a roll-retrieving door movably connected to the front of the rewinding box, an unwinding shaft rotatably connected inside the unwinding box, a single-sided adhesive test paper roll disposed on the outer side of the unwinding shaft, a motor fixedly connected to the rear side of the rewinding box, a rewinding shaft fixedly connected to the output end of the motor, the motor being used to control the rotational movement of the rewinding shaft, the end of the single-sided adhesive test paper roll furthest from the unwinding shaft being fixedly connected to the outer side of the rewinding shaft, a cotton-changing mechanism provided on the testing box for placing or removing basalt microfiber cotton, and a positioning mechanism provided on the testing box for limiting the position of the basalt microfiber cotton.

[0007] In a preferred embodiment, the cotton changing mechanism includes an observation component and a placement component. The observation component is used to observe the basalt microfiber cotton being tested, and the placement component is used to support the basalt microfiber cotton.

[0008] In a preferred embodiment, the observation assembly includes a cotton-changing cover movably connected to the front of the detection box and an observation door movably connected to the front of the detection box.

[0009] In a preferred embodiment, the placement component includes a fixed frame fixedly connected inside the testing chamber, a lower support mesh fixedly connected inside the fixed frame, and two air inlets fixedly connected to the top of the testing chamber.

[0010] In a preferred embodiment, the positioning mechanism includes a pressing component and a resetting component. The pressing component is used to press down the basalt microfiber cotton, and the resetting component is used to control the lifting and lowering movement of the pressing component.

[0011] In a preferred embodiment, the cotton pressing assembly includes a movable frame disposed above a fixed frame, an upper support net fixedly connected to the inner side of the movable frame, a connecting rod fixedly connected to the top of the movable frame, and a handle fixedly connected to the top of the connecting rod.

[0012] In a preferred embodiment, the reset assembly includes a retaining ring fixedly connected to the outside of the connecting rod and a spring fixedly connected to the top of the retaining ring, with the top of the spring fixedly connected to the top of the inside of the detection box.

[0013] The beneficial effects of this utility model are as follows: This invention uses a PLC-controlled motor to drive the take-up shaft for automatic replacement of the test paper. Its core advantage lies in effectively avoiding the accumulation and cross-contamination of different types of impurities on the test paper, ensuring that each gaseous impurity is detected on a completely new paper surface. This significantly improves the impurity differentiation and the accuracy of judging the difference in filtration effect of basalt fiber cotton on different substances, ultimately ensuring the reliability of filtration efficiency assessment and the accuracy of test results.

A single-sided adhesive test paper roll 16 is provided on the outside of the roll unwinding shaft 15. A motor 17 is fixedly connected to the rear side of the roll rewinding box 13. A roll rewinding shaft 18 is fixedly connected to the output end of the motor 17. The motor 17 is used to control the rotation of the roll rewinding shaft 18. The end of the single-sided adhesive test paper roll 16 away from the roll unwinding shaft 15 is fixedly connected to the outside of the roll rewinding shaft 18. A cotton changing mechanism is provided on the test box 1. The cotton changing mechanism is used to place or remove basalt microfiber cotton. A positioning mechanism is provided on the test box 1. The positioning mechanism is used to limit the position of the basalt microfiber cotton.

[0022] It should be noted that the internal space of the unwind box 11 and the rewind box 13 is exactly the same, so there will be no crowding when the single-adhesive side detection paper roll 16 in the unwind box 11 is completely rewound into the rewind box 13.

[0023] Refer to the instruction manual appendix Figures 1 to 2 The cotton changing mechanism includes an observation component and a placement component. The observation component is used to observe the basalt microfiber cotton being tested, and the placement component is used to support the basalt microfiber cotton.

[0024] It should be noted that both the cotton replacement cover 211 and the observation door 212 are transparent, which facilitates observation of the testing situation inside the testing box 1.

[0025] Refer to the instruction manual appendix Figure 1 The observation assembly includes a cotton changing cover 211 movably connected to the front side of the detection box 1 and an observation door 212 movably connected to the front side of the detection box 1.

[0026] It should be noted that the basalt microfiber cotton at the top of the lower support net 222 can be replaced by pulling the cotton replacement cover 211 out of the testing box 1.

[0027] Refer to the instruction manual appendix Figures 1 to 2 The placement assembly includes a fixed frame 221 fixedly connected inside the detection box 1, a lower support net 222 fixedly connected inside the fixed frame 221, and two air inlets 223 fixedly connected to the top of the detection box 1.

[0028] It should be noted that the two air inlets 223 need to be connected to the connecting pipes of the external air supply device so that the gas can be blown into the interior of the test box 1 through the external air supply device.

[0029] Refer to the instruction manual appendix Figure 5The positioning mechanism includes a pressing component and a resetting component. The pressing component is used to press down the basalt microfiber cotton, and the resetting component is used to control the lifting and lowering movement of the pressing component.

[0030] It should be noted that the dimensions of the movable frame 311 are exactly the same as those of the fixed frame 221.

[0031] Refer to the instruction manual appendix Figure 5 The cotton pressing assembly includes a movable frame 311 disposed above the fixed frame 221, an upper support net 312 fixedly connected to the inner side of the movable frame 311, a connecting rod 313 fixedly connected to the top of the movable frame 311, and a handle 314 fixedly connected to the top of the connecting rod 313.

[0032] It should be noted that the connecting rod 313 can be pulled upward by the handle 314, and the connecting rod 313 will drive the movable frame 311 to move upward until the movable frame 311 is away from the fixed frame 221. At this time, the basalt microfiber cotton can be placed on the top of the lower support net 222.

[0033] Refer to the instruction manual appendix Figure 5 The reset assembly includes a fixing ring 321 fixedly connected to the outside of the connecting rod 313, and a spring 322 fixedly connected to the top of the fixing ring 321. The top of the spring 322 is fixedly connected to the top of the inside of the detection box 1.

[0034] It should be noted that the fixed ring 321 is pushed downward by the thrust of the spring 322. The fixed ring 321 drives the movable frame 311 to move downward through the connecting rod 313 until the upper support net 312 on the inner side of the movable frame 311, together with the lower support net 222, clamps the basalt microfiber cotton, thereby limiting the position of the basalt microfiber cotton.

[0035] Working principle: First, pull the connecting rod 313 upwards using the handle 314. The connecting rod 313 then moves the movable frame 311 upwards until it moves away from the fixed frame 221. Next, open the cotton replacement cover 211 and place the basalt microfiber cotton on top of the lower support net 222. Then, use an external air supply device to blow gas into the interior of the detection box 1. At this time, the basalt microfiber cotton will filter the impurities in the gas, while the impurities that are not filtered out will fall and adhere to the single-adhesive test paper roll 16 at the bottom of the interior of the detection box 1. When it is necessary to replace the gas and blow it into the interior of the detection box 1 again, the operator starts the motor 17 through the externally connected PLC controller. The motor 17 drives the winding shaft 18 to wind up the single-adhesive test paper roll 16, thus moving the new end of the single-adhesive test paper roll 16 to the bottom position inside the detection box 1.

[0036] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
