Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, the present invention provides a building material calorific value testing device, including a testing device body 1 and a support ring 2. The testing device body 1 is installed on the top of the support ring 2. A heat insulation and sealing component 3 is fixedly connected to the outer side of the testing device body 1, and a detection heating component 4 is fixedly connected to the inner wall of the testing device body 1.

[0025] refer to Figure 3 The thermal insulation and sealing assembly 3 includes a heat insulation plate 31, a vacuum heat insulation plate 32 fixedly connected to the outside of the heat insulation plate 31, a connecting groove 33 opened on the front of the vacuum heat insulation plate 32, a sealing plate 34 movably connected inside the connecting groove 33, one side of the sealing plate 34 movably installed on one side of the inner wall of the connecting groove 33, and a heat insulation plate 35 fixedly connected to the front of the sealing plate 34.

[0026] As a technical optimization of this utility model, by setting up a heat insulation and sealing component 3, and through the good heat insulation performance of the heat insulation plate 31 and the vacuum heat insulation plate 31, the multi-layer structure design greatly reduces the heat conduction efficiency, reduces the heat exchange between the inside of the test device body 1 and the outside, avoids the situation where external stability affects the test inside the test device body 1, and enhances the use effect of the test device body 1. During the operation of the test device body 1, it always maintains a heat insulation and sealing state, prevents the transfer of heat inside and outside the device, and makes the heat change during the test process only generated by the combustion of the building material sample, ensuring the accuracy of the test data. The connecting groove 33 can easily put the sample into the test device body 1, and the sealing plate 34 can be adjusted to seal the inside of the connecting groove 33 during use, reducing the influence of the external environment on the inside of the test device body 1. At the same time, the heat insulation plate 35 can insulate the front of the sealing plate 34 during use, enhancing the heat insulation effect during use.

[0027] refer to Figure 2 The detection heating component 4 includes a temperature sensor 41, a humidity sensor 42 is fixedly connected to one side of the inner wall of the test device body 1, a controller 43 is provided on the front of the test device body 1, the controller 43 is electrically connected to the temperature sensor 41 and the humidity sensor 42 through wires, and a heating block 44 is fixedly connected to one side of the inner wall of the test device body 1.

[0028] As a technical optimization of this utility model, by setting up a detection heating component 4, a temperature sensor 41 and a humidity sensor 42, the temperature and humidity inside the monitoring device can be detected before the test, and the detection data is sent to the controller 43. The controller 43 maintains a suitable test environment temperature by controlling the working state of the heating block 44 according to the sensor data. If the humidity is detected to be excessive, the heating block 44 can be heated appropriately to accelerate the evaporation of water, thereby reducing the interference of environmental factors on the test results.

[0029] refer to Figure 2 The top of the test device body 1 is provided with a connecting groove 5, and a blower 6 is installed inside the connecting groove 5. The blower 6 is electrically connected to the controller 43 through a wire.

[0030] As a technical optimization of this utility model, by setting up a connecting slot 5 and a blower 6, the connecting slot 5 can connect the inside of the test device body 1 with the outside during use. When the air inside the test device body 1 is humid, the blower 6 can be started to promote air circulation inside the device. At the same time, the air circulation can also ensure sufficient oxygen supply during combustion, so that the building material sample can burn completely and improve the reliability of the test results. The blower 6 can adjust the wind speed according to the instructions of the controller 43 to meet the needs of different test stages. After the combustion test starts, the controller 43 starts the blower 6 according to the preset combustion conditions and sensor feedback information. Air enters the device through the connecting slot 5 to provide the necessary oxygen for the combustion of building materials, ensuring that the combustion reaction is fully carried out and that the released heat can accurately reflect the calorific value of the building materials.

[0031] refer to Figure 2 A heat insulation ring 7 is movably connected to the top of the blower 6, and an electric push rod 8 is fixedly connected to one side of the heat insulation ring 7.

[0032] As a technical optimization of this utility model, by setting up a heat insulation ring 7 and an electric push rod 8, it is convenient for users to control the heat transfer between the blower 6 and the inside of the testing device. When blowing is not required, the electric push rod 8 pushes the heat insulation ring 7 to close the blower 6, reducing heat loss. During the blowing process, the position of the heat insulation ring 7 can be adjusted as needed to balance heat and ventilation effect. When in use, the electric push rod 8 is started by the controller 43. The electric push rod 8 receives the signal from the controller 43 and generates a telescopic movement, which drives the heat insulation ring 7 to move on the top of the blower 6. When it is necessary to reduce heat loss, the heat insulation ring 7 completely covers the top opening of the blower 6. When ventilation is required and heat transfer needs to be controlled, the heat insulation ring 7 can be moved to an appropriate position to minimize heat exchange while ensuring ventilation.

[0033] refer to Figure 2The blower 6 has filter plates 9 installed at both the intake and output ends. A ventilation slot 10 is provided at the bottom of the outer side of the test device body 1, and a filter ring 11 is installed inside the ventilation slot 10.

[0034] As a technical optimization of this utility model, by setting up a filter plate 9, a ventilation slot 10 and a filter ring 11, it is convenient for users to purify the air entering and exiting the device. The filter plate 9 can prevent dust and other impurities from entering the blower 6 and the interior of the testing device, so as to avoid affecting the normal operation of the testing equipment. The ventilation slot 10 and the filter ring 11 can effectively filter harmful gases and particulate matter produced by combustion. The filter plate 9 physically intercepts larger particles such as dust in the air through its fine mesh structure. The ventilation slot 10 provides a channel for air circulation.

[0035] refer to Figure 2 A movable block 12 is movably connected to the outside of the ventilation slot 10, and a cylinder 13 is fixedly connected to the back of the movable block 12. The cylinder 13 is installed on the top of the support ring 2.

[0036] As a technical optimization of this utility model, by setting a moving block 12 and a cylinder 13, the moving block 12 can limit and protect the outer side of the filter ring 11 during use, and at the same time, it can also facilitate the user to control the ventilation of the connecting groove 33. When it is necessary to close the connecting groove 33, the cylinder 13 can be activated, so that the output end of the cylinder 13 pushes the moving block 12 to move. After the moving block 12 moves to the outer side of the ventilation groove 10, it can be sealed and limited.

[0037] refer to Figure 3 A protective box 14 is fixedly connected to the outside of the vacuum insulation plate 32, a protective plate 15 is fixedly connected to the front of the insulation plate 35, an electric push rod 8 is installed on the top of the protective box 14, and a controller 43 is installed on the front of the protective box 14.

[0038] As a technical optimization of this utility model, by setting up a protective box 14 and a protective plate 15, the protective box 14 can protect the outside of the vacuum insulation plate 32 during use, preventing the vacuum insulation plate 32 from being damaged by external influences. At the same time, the protective plate 15 can protect the front of the insulation plate 35, enhancing the safety of use.

[0039] The working principle and usage process of this utility model are as follows: First, the building material sample is placed in the designated position inside the main body 1 of the testing device. The main body 1 is then started. The controller 43 controls the temperature sensor 41 and humidity sensor 42 to begin working, monitoring the temperature and humidity inside the device in real time. If the ambient temperature is too low or the humidity is too high, the controller 43 will start the heating block 44 according to a preset program for heating. Then, the blower 6 is started for ventilation, working in conjunction with the heat generated by the heating block 44 to quickly heat, ventilate, and dehumidify, ensuring that the inside of the main body 1 of the testing device reaches suitable testing environmental conditions. The controller 43 controls the blower 6 to work, blowing air into the device through the connecting groove 33, providing sufficient oxygen for the combustion of the building material sample. The heat insulation plate 31 and the vacuum insulation plate 32 prevent external temperature environment interference in the testing process, achieving the effect of heat insulation detection. This effectively avoids interference from external environmental factors, providing reliable data support for the evaluation of building material combustion performance and enhancing the effectiveness of the testing device.

[0040] In summary, this building material calorific value testing device solves the problem of existing testing devices being susceptible to interference from the external environment during use. Fluctuations in ambient temperature, humidity, and other factors can cause deviations in the test results, severely affecting the accuracy of the test. This not only brings many inconveniences during operation but also greatly weakens the practicality and reliability of the testing device, failing to meet the needs of accurate testing and reducing the effectiveness of the testing device.
