[0002] To assess the safety and performance of thermal insulation materials in a fire, combustion tests are required. Combustion tests determine the material's reaction under high temperature and flame conditions. By conducting these tests, it can be determined whether the material is easily combustible, thereby assessing its threat to life and property.

[0003] A search revealed Chinese patent CN219608860U, which discloses a device for testing the combustion performance of building insulation materials. The device includes a test chamber with a partition fixedly installed inside. An insulation layer is also installed inside the test chamber. A motor is fixedly installed on the inner bottom wall of the test chamber, and a screw is fixedly connected to the output shaft of the motor. A movable block is sleeved on the outer surface of the screw, and an installation mechanism is provided on the top of the movable block. A sealing door is movably installed on the left side of the test chamber, and a gas cylinder is movably installed on the top of the test chamber. A corrugated connecting pipe is fixedly connected to the output end of the gas cylinder. This device for testing the combustion performance of building insulation materials, through its installation mechanism, provides convenient adjustment and fixing functions. It can clamp and fix materials of different sizes for easy combustion performance testing, effectively improving the flexibility of the equipment. It also allows for convenient cleaning of combustion residue.

[0004] The aforementioned patent for a device for testing the combustion performance of building insulation materials has the following shortcomings: it is inconvenient to disassemble and assemble the filter cover; particulate impurities easily adhere to the filter, requiring regular cleaning to ensure its unobstructed flow in order to maintain the normal operation of the equipment; if disassembly and assembly are difficult, it will consume a lot of time and effort, thereby affecting the efficiency of maintenance work and the progress of testing work. Therefore, it is necessary to design a device for testing the combustion performance of insulation materials to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combustion testing device for thermal insulation materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A thermal insulation material combustion testing device includes a test chamber with a waste discharge pipe fixedly connected to it. The waste discharge pipe has four positioning slots, each containing a positioning rod. A common cover plate is fixedly connected to the same side of each of the four positioning rods. A groove is formed on the side of the cover plate near the waste discharge pipe, containing a fixing frame. The fixing frame is positioned on the side of the waste discharge pipe near the cover plate. A filter cover is fixedly connected to the inner wall of the fixing frame. Limiting sleeves are fixedly connected to the top and bottom of the cover plate, each with a limiting groove. Limiting rods are set in two of the limiting grooves, and a common fixing plate is fixedly connected to the same side of each of the two limiting rods. A pressure plate is fixedly connected to one side of the fixing plate. A sealing door is installed on one side of the test chamber. A quick-release mechanism is used to install the filter cover, and closing the sealing door secures the filter cover. This technical solution allows the limiting rod to remain stably positioned within the limiting groove after the sealing door is closed, thus fixing the position of the limiting sleeve and ensuring the cover plate is securely placed on the fixed frame. This guarantees the stability of the filter cover. Opening the sealing door allows the limiting rod to be removed from the limiting groove, separating the cover plate from the fixed frame and enabling the filter cover to be removed for cleaning. This effectively solves the problems mentioned in the background technology, such as the inconvenience of disassembling and assembling filter covers in most existing equipment, the easy adhesion of particulate impurities to the filter, the need for regular cleaning to ensure its smooth operation, and the time and effort required for disassembly and assembly, which affects the efficiency of maintenance and the progress of testing. This solution enables operators to easily disassemble and install filter covers, greatly reducing the time and effort required for daily maintenance, improving the operability of the equipment, and enhancing overall work efficiency.

[0007] As a further embodiment of this invention, the sealed door is provided with an observation window.

[0008] As a further embodiment of this utility model, the fixing plate has a limiting cylinder fixedly connected to both ends on the side near the cover plate. A guide rod is provided through both the limiting cylinder and the fixing plate. The limiting cylinder and the fixing plate are slidably connected to the guide rod. Both guide rods are fixedly connected to the inner wall of the test chamber.

[0009] As a further embodiment of this utility model, a fan is fixedly connected to the waste discharge pipe on the side away from the cover plate.

[0010] As a further embodiment of this utility model, a placement platform is fixedly connected to the bottom inner wall of the test box.

[0011] As a further embodiment of this utility model, an automatic burner is fixedly connected to the top inner wall of the test chamber, and a gas guide pipe is fixedly connected to the input end of the automatic burner. The gas guide pipe passes through one side of the test chamber and is connected to an external natural gas supply device.

[0012] As a further embodiment of this utility model, an air inlet pipe is fixedly connected to one side of the test box, and the air inlet pipe is connected to an external air supply device.

[0013] The beneficial effects of this utility model are as follows: Because of the adoption of a quick-release mechanism for installing the filter cover and the technique of fixing the filter cover after closing the sealing door, the limiting rod can be stably positioned in the limiting groove after the sealing door is closed, thus fixing the position of the limiting sleeve plate. This allows the cover plate to be stably placed on the fixed frame, ensuring the stability of the filter cover position. Opening the sealing door allows the limiting rod to be removed from the limiting groove, separating the cover plate from the fixed frame, and allowing the filter cover to be removed for cleaning. This effectively solves the problems mentioned in the background technology, such as the inconvenience of disassembling and assembling filter covers in most existing equipment, the easy adhesion of particulate impurities on the filter, the need for regular cleaning to ensure its smooth operation, and the time and effort required for disassembly and assembly to be difficult, which affects the efficiency of maintenance work and the progress of testing. This technology enables operators to easily disassemble and install filter covers, greatly reducing the time and effort required for daily maintenance, improving the operability of the equipment, and improving the overall work efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A thermal insulation material combustion testing device includes a test chamber 1, a waste discharge pipe 2 passing through the test chamber 1 and fixedly connected to the test chamber 1. The waste discharge pipe 2 has four positioning grooves 3, each containing a positioning rod 4. A common cover plate 5 is fixedly connected to the same side of the four positioning rods 4. A groove 6 is formed on the side of the cover plate 5 near the waste discharge pipe 2, containing a fixing frame 7. The fixing frame 7 is located on the side of the waste discharge pipe 2 near the cover plate 5. A filter cover 8 is fixedly connected to the inner wall of the fixing frame 7. Limiting sleeves 9 are fixedly connected to the top and bottom of the cover plate 5. Limiting sleeves 9 have limiting grooves 10, each containing a limiting rod 11. A common fixing plate 12 is fixedly connected to the same side of the two limiting rods 11. A pressure plate 13 is fixedly connected to one side of the fixing plate 12. A sealing door 17 is installed on one side of the test chamber 1. A quick-release mechanism is used to install the filter cover and to secure the device after closing the sealing door. By employing a precise technical method to fix the filter cover, the limiting rod can stably reside within the limiting groove after the sealing door is closed, thus securing the position of the limiting sleeve plate. This allows the cover plate to stably cover the fixed frame, ensuring the stability of the filter cover's position. Opening the sealing door allows the limiting rod to be removed from the limiting groove, separating the cover plate from the fixed frame, and enabling the filter cover to be removed for cleaning. This effectively solves the problems mentioned in the background technology, such as the inconvenience of disassembling and assembling filter covers in most existing equipment, the easy adhesion of particulate impurities to the filter, the need for regular cleaning to ensure its unobstructed flow, and the time and effort required for difficult disassembly and assembly, which affects the efficiency of maintenance work and the progress of testing. This technology allows operators to easily disassemble and install filter covers, greatly reducing the time and effort required for daily maintenance, improving equipment operability, and enhancing overall work efficiency.

[0018] In this embodiment, an observation window is provided on the sealed door 17.

[0019] In this embodiment, the fixing plate 12 is fixedly connected to the limiting cylinders 14 at both ends on the side near the cover plate 5. Guide rods 15 are provided on both the limiting cylinders 14 and the fixing plate 12. The limiting cylinders 14 and the fixing plate 12 are slidably connected to the guide rods 15. The two guide rods 15 are fixedly connected to the inner wall of the test box 1. When the fixing plate 12 moves, it will drive the limiting cylinders 14 to move along the guide rods 15 to ensure the stability of the fixing plate 12 when it moves.

[0020] In this embodiment, a fan 16 is fixedly connected to the waste discharge pipe 2 on the side away from the cover plate 5.

[0021] In this embodiment, a placement platform 18 is fixedly connected to the bottom inner wall of the test box 1.

[0022] In this embodiment, an automatic burner 19 is fixedly connected to the top inner wall of the test chamber 1. A gas guide pipe 20 is fixedly connected to the input end of the automatic burner 19. The gas guide pipe 20 passes through one side of the test chamber 1 and is connected to an external natural gas supply device. The natural gas output by the external natural gas supply device is injected into the automatic burner 19 through the gas guide pipe 20. The automatic burner 19 ignites it and sprays the flame toward the insulation material placed on the placement platform 18 for combustion testing.

[0023] In this embodiment, an air inlet pipe 21 is fixedly connected to one side of the test chamber 1. The air inlet pipe 21 is connected to an external air supply device. Oxygen is injected into the test chamber 1 through the external air supply device to assist combustion and ensure complete combustion.

[0024] Working principle: In use, open the sealed door 17, place the insulation material to be tested on the placement platform 18, then close the sealed door 17. Gas is supplied through the external natural gas supply device via the gas pipe 20 and injected into the automatic burner 19. The automatic burner 19 ignites the gas and sprays it onto the insulation material for combustion testing. Observe the combustion through the observation window on the sealed door 17. When using an external power supply, start the fan 16. The fan 16 draws out the exhaust gas generated by combustion in the test chamber 1, filters particulate impurities in the exhaust gas through the filter cover 8. After completing the combustion test, open the sealed door 17 and remove the insulation material. When it is necessary to clean the filter cover 8, pull the pressure plate 13. The pressure plate 13 will move the fixing plate 12, which will move the limiting cylinder 14 along the guide rod 15. The movement of the fixing plate 12 will also move the limiting rod 11 out of the limiting groove 10, thus releasing the insulation material. In addition to restricting the cover plate 5, the cover plate 5 can be moved, which will cause the positioning rod 4 to move out of the positioning groove 3, so the cover plate 5 can be removed. This also releases the restriction on the fixing frame 7, allowing the fixing frame 7 to be removed, and the filter cover 8 to be removed. This allows for the cleaning of the filter cover 8, preventing excessive particulate matter from adhering to the filter cover 8 and preventing exhaust gas from being discharged. During installation, the fixing frame 7 is inserted into the groove 6, and then the positioning rod 4 is inserted into the positioning groove 3 to ensure the accurate position of the cover plate 5. Pushing the cover plate 5 makes the fixing frame 7 contact the exhaust pipe 2. At this time, the limiting groove 10 and the limiting rod 11 are coaxial, so the fixing plate 12 can be pushed to insert the limiting rod 11 into the limiting groove 10, thus restricting the position of the cover plate 5. When the sealing door 17 is closed, the sealing door 17 will contact the pressure plate 13, ensuring the stability of the position of the fixing plate 12 and preventing the limiting rod 11 from moving out of the limiting groove 10, thus completing the installation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
