Description

Technical Field

[0001] The utility model relates to the technical field of film combustion equipment, in particular to a film horizontal and vertical combustion tester. Background Technique

[0002] The horizontal and vertical combustion test uses a Bunsen burner with a standard specified size and a specific gas source (methane or propane), and applies a flame to a sample in a horizontal or vertical state at a certain flame height and a certain flame application angle for a certain period of time, and evaluates its flammability and fire hazard according to the ignition time, the duration of glowing combustion, and the combustion length, etc.

[0003] According to the requirements in DL / T 376-2019 "General Technical Conditions for Insulating Materials for Polymer Insulator Skirts and Sheaths", it is necessary to conduct a flammability test on the film. According to GB / T 10707

[0004] -2008 "Determination of Rubber Combustion Performance" standard, there are clear regulations for both the flame height and the distance between the flame and the specimen. In the existing horizontal and vertical combustion tester, the positions of the Bunsen burner and the specimen are adjusted manually by humans. It is difficult to control the flame height and the distance between the flame and the specimen with the Bunsen burner, resulting in situations where the test does not meet the standard requirements. A large amount of toxic and harmful gases may be generated during the combustion of the specimen. If the operator opens the box and adjusts manually, it will cause environmental pollution or poisoning of the operator. Content of the Utility Model

[0005] The utility model provides a film horizontal and vertical combustion tester to solve the above problems.

[0006] To solve the above technical problems, the technical solution of the utility model is: a film horizontal and vertical combustion tester, including a test box, a slide rail is fixedly installed at the bottom of the inner cavity of the test box, a slider is slidably connected to the slide rail, a Bunsen burner base is fixedly installed on the top of the slider, and an adjustable Bunsen burner is installed on the Bunsen burner base; a film support rod is fixedly installed in the upper part of the inner cavity of the test box, and a film clamp is arranged at the end of the film support rod; the Bunsen burner base is connected to a methane gas cylinder through a gas pipe.

[0007] Further, the test box is a hollow cuboid structure.

[0008] Further, a film support rod is horizontally and fixedly installed on the side wall of the upper part of the inner cavity of the test box.

[0009] Further, the film clamp is located above the adjustable Bunsen burner.

[0010] Further, one end of the gas pipe is connected to the Bunsen burner base, and the other end passes through the test box and is connected to the methane gas cylinder.

[0011] The utility model can control the flame height through an adjustable Bunsen burner, and control the distance between the flame and the specimen by fixing the position between the test chamber and the adjustable Bunsen burner, meeting the standard requirements and avoiding environmental pollution and operator poisoning.

[0014] The following Figure 1 further describes the specific embodiments of the utility model in conjunction with the attached drawings.

[0015] The horizontal and vertical film burning instrument includes a test chamber 1. The test chamber 1 is a cavity cuboid structure. A slide rail 7 is fixedly installed at the bottom of the inner cavity of the test chamber 1. A slide block 9 is slidably connected to the slide rail 7. A Bunsen burner base 6 is fixedly installed on the top of the slide block 9. An adjustable Bunsen burner 2 is installed on the Bunsen burner base 6. A film support rod 5 is horizontally and fixedly installed on the upper side wall of the inner cavity of the test chamber 1. A film clamp 10 is provided at the end of the film support rod 5. The film clamp 10 is located above the adjustable Bunsen burner 2. The Bunsen burner base 6 is connected to a methane gas cylinder 4 through a gas pipe 3. One end of the gas pipe 3 is connected to the Bunsen burner base 6, and the other end passes through the test chamber 1 and is connected to the methane gas cylinder 4.

[0016] Open the switch of the methane gas cylinder 4. Methane gas enters the adjustable Bunsen burner 2 through the gas pipe 3. Ignite the adjustable Bunsen burner 2. Control the flame height through the valve on the adjustable Bunsen burner 2. After the flame height is stable, put the film specimen 8 into the test chamber 1 and conduct the flammability test of the film specimen 8 according to the standard procedure, measure and record the flaming combustion time and non-flaming combustion time of the film specimen 8.
