Detailed Implementation Methods

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] Please refer to Figures 1 to 7 As shown in the figure, the following describes the flammability test of the hot fuel oil test machine provided by the present invention with reference to the embodiments. The test machine includes a test machine housing, an electronic pulse ignition device, a heating module device, a smoke exhaust system, and a control module.

[0021] The outer casing of the testing machine includes a stainless steel casing 1, a flat base bracket 2 at the bottom of the stainless steel casing 1, universal casters 3 around the flat base bracket 2, a flat base 4 inside the flat base bracket 2; a fan base 5 at the top of the stainless steel casing 1; a power switch 6 on one side of the stainless steel casing 1; an operation interface 7; a transparent observation window 8 on the other side of the stainless steel casing 1; an ignition receiving space inside the transparent observation window 8 on one side of the interior of the stainless steel casing 1 for completing the ignition action; a module receiving space on the other side of the interior of the stainless steel casing 1 for installing or housing the control module; a bottom shell frame 9 at the bottom inside the ignition receiving space; and a crossbeam frame 10 at the lower end inside the ignition receiving space for suspending or fixing the electronic pulse telephone device.

[0022] The electronic pulse ignition device includes an ignition needle 11, an ignition controller for controlling the ignition action of the ignition needle 11, and an ignition relay for controlling the power-on or power-off action of the ignition controller. The ignition controller is composed of a module of a gas infrared pulse power supply 17. In use, the ignition controller outputs high voltage to ignite the ignition needle 11.

[0023] The heating module device includes a heating module 12 connected to a crossbeam 10 inside a stainless steel housing 1, an ignition oil cup 13 mounted on the heating module 12 and used in conjunction with an ignition needle, a stepper motor for controlling the pouring action of fuel in the ignition oil cup 13, a stepper motor driver for controlling the stepper motor, and a heating relay for controlling the on / off action of the heating module 12.

[0024] The smoke exhaust system includes an exhaust fan 14 mounted on a fan base at the top of a stainless steel housing, and an exhaust stepper motor connected to the exhaust fan 14.

[0025] During installation, the electronic pulse ignition device, heating module, exhaust system, and control module are integrated and installed inside the testing machine's outer casing. The electronic pulse ignition device is primarily used to perform the ignition action. The heating module is used to heat the fuel oil to achieve the ignition temperature. The exhaust system is mainly used to control the smoke and heat generated during fuel combustion, ensuring a safe and clean environment inside the testing machine's outer casing.

[0026] In this invention, the control module includes a control touch panel, a PLC controller 15, a sensor 21, a switching power supply 16, relays 18, a stepper motor 19, a stepper motor driver 20, and an infrared pulse power supply 17. The user can issue commands through the control touch panel to control the entire experimental process. The PLC controller 15, as the central processing unit, receives commands from the control touch panel and executes corresponding operations to control other components. The three relays 18 are mainly used to control the power supply to the exhaust fan, heating module, and gas infrared ignition controller, respectively, enabling remote control of these devices. The three relays 18 are a heating relay, an ignition relay, and an exhaust relay. The ignition controller generates a high-voltage current, which is transmitted through the ignition needle 11 to the ignition oil cup 13, generating a spark to ignite the fuel. The ignition needle 11 is mainly responsible for the actual ignition process, converting the high-voltage current into a spark. The stepper motor driver 20 is used to drive the stepper motor 19, controlling its speed and direction, thereby controlling the pouring of fuel in the ignition oil cup 13. The stepper motor 19 is mainly responsible for tilting and pouring the fuel from the ignition cup 13 to ensure uniform combustion. The sensor 21 mainly serves as a limiting device to prevent excessive rotation of the ignition cup 13, ensuring experimental safety. The switching power supply 16 mainly provides the necessary power to control the touch panel and the stepper motor driver 20. The stainless steel enclosure 1 houses all components, protects the equipment from external environmental influences, ensures the experimental enclosure, and enables automated control of the fuel combustion process, ensuring efficient, accurate, and safe experiments.

[0027] In operation, the experimental combustion sample is first placed directly below the heating module 12, and the ignition fuel cup 13 is filled with fuel. A command is sent to the PLC controller 15 via the control touch panel, which in turn controls the heating relay J3 to close and energize, activating the heating module to heat the fuel. Once a certain temperature is reached, the PLC controller 15 then controls the ignition relay J2 to close and energize, sending a command to the ignition controller to open the gas solenoid valve. A high-voltage current is output, passing through the ignition needle 11 above the ignition fuel cup 13, generating a spark to ignite the heated fuel in the ignition fuel cup 13. Next, a command is sent to the PLC controller 15 via the control touch panel, which drives the stepper motor driver 20 to rotate the stepper motor 19, causing the fuel in the ignition fuel cup 13 to tilt and pour out, thus allowing the experimental sample to burn. After the experimental sample completes the combustion test, the PLC controller 15 is sent a command through the control touch panel. The PLC controller 15 then controls the exhaust relay J1 to close and energize, starting the exhaust system to discharge the heat and smoke inside the stainless steel box 1 through the pipes. This ensures that the experimental environment can be cleaned and cooled in a timely manner after the experiment, preparing for the next experiment.

[0028] The entire experimental process is precisely controlled by a PLC controller 15 to ensure the accuracy and repeatability of experimental data. As the core control unit, the PLC controller 15 is responsible for receiving and processing instructions from the control panel, coordinating the operation of various subsystems, and ensuring the smooth progress of the experiment. The described glow fuel oil testing machine is a device specifically designed for testing the bottom samples of fire-resistant protective enclosures of audio-visual or information technology equipment. By integrating heating, ignition, and smoke extraction systems into one unit, and equipped with a transparent observation window and a user-friendly interface, it enables users to conduct experiments efficiently, accurately, and safely.

[0029] In this test, ignition is achieved through an electronic pulse ignition device, and the heating module is used to burn fuel oil. The combustion gases generated during fuel oil combustion are discharged to the outside of the stainless steel housing 1 through the exhaust system. This integrates ignition, heating, and exhaust into one unit. With the configuration of a transparent observation window 8 and a simple operating interface, the flammability tester can be more efficient, accurate, and safe for the tester.

[0030] The preferred embodiments of this utility model have been described above with reference to the accompanying drawings, but this does not limit the scope of the utility model. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of this utility model should be within the scope of the utility model.
