Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to an electro-ignition monitoring device based on a multi-channel isothermal microcalorimeter. Background Technology

[0002] A multichannel isothermal calorimeter is a precision instrument that measures the thermal changes of a substance at a constant temperature. It is suitable for monitoring the combustion process of combustible materials such as coal and energetic thin film materials, providing reliable data support for industrial combustion process optimization and energy assessment.

[0003] When using a multi-channel isothermal calorimeter to test the calorific value of materials such as energetic thin films, it is inconvenient to ignite the energetic thin film material quickly because it is placed inside the test furnace before ignition. Furthermore, the substances generated after ignition enter the interior of the test furnace, which can easily contaminate the interior of the test furnace.

[0004] Therefore, it is necessary to develop a new electro-ignition monitoring device based on a multi-channel isothermal microcalorimeter to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an electro-ignition monitoring device based on a multi-channel isothermal microcalorimeter that can rapidly ignite and expel combustion gases from energetic thin film materials and other related materials.

[0006] To solve the above-mentioned technical problems, the electro-ignition monitoring device based on a multi-channel isothermal micro calorimeter provided by this utility model includes: a support rod, which is fixedly connected to a bottle stopper, a metal stopper, and a rubber stopper in sequence, the bottle stopper engaging a storage bottle; an electrode rod is symmetrically fixedly connected to the bottom surface of the bottle stopper, the electrode rod extending into the interior of the storage bottle, and a conductive wire is installed at the top of the electrode rod, the conductive wire passing through the metal stopper and the rubber stopper; the metal stopper and the rubber stopper are fixedly connected to a connecting tube, and the bottom end of the connecting tube passes through the bottle stopper and communicates with the interior of the storage bottle.

[0007] Preferably, a terminal block is installed at the top of the rubber plug, and the terminal block is fixedly connected to the top of the conductive wire.

[0008] Preferably, the interior of the rubber stopper and the metal stopper is filled with a heat-insulating cotton layer, and the conductive wire passes through the heat-insulating cotton layer.

[0009] Preferably, the rubber stopper and the metal stopper are fitted inside the test furnace, and the storage bottle is located inside the test furnace.

[0010] Preferably, a connector is installed at the top of the rubber stopper, and the connector is in communication with the connecting pipe.

[0011] Preferably, the surface of the bottle stopper is provided with a groove, and a locking block is slidably connected inside the groove, with one end of the locking block engaging with the interior of the storage bottle; a spring is installed on one side of the groove, and one end of the spring is connected to the locking block.

[0012] Preferably, the bottom surfaces of both the groove and the card block are inclined, and one end of the card block has a trapezoidal structure.

[0013] Compared with related technologies, the electro-ignition monitoring device based on a multi-channel isothermal micro calorimeter provided by this utility model has the following beneficial effects: This invention provides an electro-ignition monitoring device based on a multi-channel isothermal micro calorimeter. When it is necessary to test the calorific value of materials such as energetic thin films, the energetic thin film material is placed inside the storage bottle, and then the storage bottle is sealed with the stopper. The electrode rod enters the storage bottle and contacts the energetic thin film material. The storage bottle is then placed inside the test furnace, and the metal stopper and rubber stopper seal the interior of the test furnace. When it is necessary to ignite the energetic thin film material, the conductive wires are connected to high voltage. The current enters the electrode rod and forms positive and negative electrodes inside the storage bottle. The high potential difference between the positive and negative electrodes generates an electric field. When the voltage exceeds the ionization threshold of gas molecules, the gas molecules are ionized to form a conductive channel. Accompanied by instantaneous high temperature and popping sound, a visible electric spark is formed, thereby quickly igniting the energetic thin film material inside the storage bottle, facilitating the combustion test of the energetic thin film material. The energetic thin film burns inside the storage bottle, and the burned material remains inside the storage bottle. The gas produced after combustion is discharged through the connecting pipe to avoid contaminating the interior of the test bottle. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1 to 4 , Figure 1 A schematic diagram of a preferred embodiment of the electro-ignition monitoring device based on a multi-channel isothermal micro calorimeter provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the storage bottle. Figure 3 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 4 for Figure 2 The diagram shows a top view of the metal plug structure. An electro-ignition monitoring device based on a multi-channel isothermal microcalorimeter includes a support rod 3, which is sequentially fixedly connected to a bottle stopper 61, a metal stopper 2, and a rubber stopper 1. The bottle stopper 61 engages with a storage bottle 6. An electrode rod 42 is symmetrically fixedly connected to the bottom surface of the bottle stopper 61, extending into the storage bottle 6. A conductive wire 4 is installed at the top of the electrode rod 42, passing through the metal stopper 2 and the rubber stopper 1. The metal stopper 2 and the rubber stopper 1 are fixedly connected to a connecting pipe 51, with the bottom end of the connecting pipe 51 penetrating the bottle stopper 61 and connecting to the interior of the storage bottle 6. The rubber stopper 1 and the metal stopper 2 engage with the interior of a testing furnace 7, and the storage bottle 6 is located inside the testing furnace 7. When it is necessary to test the calorific value of materials such as energetic thin films, the energetic thin film material is placed inside the storage bottle 6, and then the storage bottle 6 is sealed with the bottle stopper 61. The electrode rod 42 enters the storage bottle 6 and contacts the energetic thin film material. The storage bottle 6 is then placed inside the test furnace 7, and the metal stopper 2 and the rubber stopper 1 seal the interior of the test furnace 7. When it is necessary to ignite the energetic thin film material, the conductive wire 4 is connected to a high voltage. The current enters the electrode rod 42 and forms positive and negative electrodes inside the storage bottle 6. The high potential difference between the positive and negative electrodes generates an electric field. When the voltage exceeds the ionization threshold of gas molecules, the gas molecules are ionized to form a conductive channel. Accompanied by instantaneous high temperature and popping sound, a visible electric spark is formed, thereby quickly igniting the energetic thin film material inside the storage bottle 6, which facilitates the combustion test of the energetic thin film material. The energetic thin film burns inside the storage bottle 6, and the burned material remains inside the storage bottle 6. The gas produced after combustion is discharged through the connecting pipe 51 to avoid contaminating the interior of the test bottle 6.

[0018] A terminal block 41 is installed at the top of the rubber plug 1. The terminal block 41 is fixedly connected to the top of the conductive wire 4. In order to place the terminal block 41 outside the test furnace 7, an external wire is connected to the terminal block 41 to transmit high voltage electricity into the conductive wire 4 and the electrode rod 42.

[0019] The rubber stopper 1 and the metal stopper 2 are filled with a heat insulation cotton layer 8, and the conductive wire 4 passes through the heat insulation cotton layer 8 in order to increase the sealing performance of the rubber stopper 1 and the metal stopper 2 and prevent heat leakage from the inside of the test furnace 7.

[0020] The top of the rubber stopper 1 is fitted with a connector 5, and the connector 5 is connected to the connecting tube 51. In order to facilitate the connection of the connector 5 to other equipment and instruments, the gas generated by the combustion of the substance is transported into other equipment and instruments through the connecting tube 51 and the connector 5, so as to facilitate the detection of the gas after combustion; or experimental reagents are added to the inside of the storage bottle 6 through the connecting tube 51.

[0021] The bottle stopper 61 has a groove 62 on its surface, and a locking block 64 is slidably connected inside the groove 62. One end of the locking block 64 engages with the interior of the storage bottle 6. A spring 63 is installed on one side of the groove 62, and one end of the spring 63 is connected to the locking block 64. When the bottle stopper 61 engages with the storage bottle 6, the spring 63 extends and pushes the locking block 64 to move inside the groove 62, so that the locking block 64 enters the interior of the storage bottle 6, thereby fixing the bottle stopper 61 to the top of the storage bottle 6 and sealing the interior of the storage bottle 6.

[0022] The bottom surfaces of the groove 62 and the locking block 64 are both inclined to facilitate the locking block 64 sliding down along the groove 62 and locking into the interior of the storage bottle 6, thereby increasing the stability of the locking block 64 inside the storage bottle 6 and providing stability between the storage bottle 6 and the bottle stopper 61; and one end of the locking block 64 has a trapezoidal structure to facilitate the locking block 64 entering the interior of the storage bottle 6.
