specific Embodiment approach

[0042] Before the start of the test, according to the requirements of GB / T 21631-2008 for sampling and sample processing, the spray aerosol closed space ignition tester is turned on, and the product name, net capacity, initial loading level, etc. are manually input on the host computer, and the temperature and humidity sensor SHT11 The temperature and humidity of the environment are collected and transmitted to the host computer. Light the candle 21, and the right end is sealed with a 0.01 to 0.02 mm thick plastic film. Place a full gas tank on the base 32, turn the third handle 44 counterclockwise, adjust the height of the base 32, make the nozzle and the round hole 30 on the cylindrical experimental container 15 equal height, and turn the third handle 44 clockwise , Fixed base 32 height. Adjust the adjusting screw mandrel 10 in the aerosol automatic spraying mechanism so that the pressure head 51 is aimed at the nozzle. Adjust the first handle 17 so that a circular hole 30...

Abstract

The invention discloses a spray aerosol enclosed space ignition tester, which comprises a gas tank automatic turning mechanism, an aerosol automatic spraying mechanism, a gas tank positioning clipping mechanism, a gas tank height adjusting mechanism, an enclosed structure, an ignition source mechanism, a combustion detecting unit and a processing circuit; one side of a platform is provided with a door-shaped frame, of which the upper part is provided with the gas tank automatic turning mechanism; one side of a gas tank fixing platform is fixed with the gas tank automatic turning mechanism, while the other side is provided with the aerosol automatic spraying mechanism, the gas tank positioning clipping mechanism and the gas tank height adjusting mechanism from top to bottom in sequence; the other side of the platform is provided with a cylindrical experiment container, in which the top part is provided with the combustion detecting unit and the bottom part is provided with the ignition source mechanism; and the processing circuit, the door-shaped frame and the gas tank automatic turning mechanism are enclosed in an electric cabinet, on which a displayer and a control keyboard are arranged. The tester has the advantages of realization of automatic detection, high accuracy and good safety.

Description

technical field [0001] The invention relates to a dangerous goods tester, in particular to a spray aerosol closed space ignition tester. Background technique [0002] Spray aerosols are dangerous goods in international trade. The "Recommendations on the Transport of Dangerous Goods: Manual of Tests and Standards" issued by the United Nations requires that spray aerosols be tested for ignition distance, and relevant test standards have been formulated. Among them, the spray aerosol closed space ignition tester is used to measure the flammability of spray aerosol products within a spraying distance of 15cm, so as to evaluate the degree of fire hazard. [0003] At present, my country's testing methods for spray aerosols are quite different from international standards. Marking the Globally Harmonized System, my country's new national standard "GB / T 21631-2008 Ignition Test Method for Hazardous Goods Sprays in Enclosed Spaces" implemented in September 2008. [0004] At present,...
