TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium phosphide deliquescence rate detection, specifically to an aluminium phosphide deliquescence rate detection device. BACKGROUND

[0002] Aluminium phosphide is usually used as a broad-spectrum fumigation insecticide, mainly for fumigating warehouse pests, various space pests, stored grain pests, seed pests, and outdoor rodents in caves. After aluminium phosphide absorbs water, it will immediately produce highly toxic phosphine gas. In this process, an aluminium phosphide deliquescence rate detection device is needed to detect the generation rate of phosphine gas.

[0003] For example, the aluminium phosphide deliquescence rate detection device in Chinese patent application No. CN201420643377.4 includes a box with heat insulation performance. A taking door is arranged on the front of the box, and an observation window, a taking operation hole, a one-way air inlet for pressing during air tightness detection of the box, and a detection port for connecting an air tightness detector are arranged on the top of the box.

[0029] The exhaust pipe 83 penetrates through the rear side of the body 1 and extends into the gas outlet cavity 5, the two side walls of the purification tank 84 are fixedly provided with a blocking rod 85, and the mounting frame 86 is movably connected to the top of the two blocking rods 85.

[0030] The gas pump 82 is fixedly provided with a U-shaped exhaust pipe 87 at the gas outlet, the bottom end of the U-shaped exhaust pipe 87 penetrates through the box body 81 and one side of the purification tank 84 and extends to the bottom end inside the purification tank 84, and the mounting frame 86 is arranged on the bottom end of the U-shaped exhaust pipe 87, the top of the purification tank 84 is fixedly provided with an exhaust pipe 88, and the top of the exhaust pipe 88 is fixedly provided with an electric valve 89, so as to open the electric valve 89 and discharge the clean gas in the purification tank 84 through the exhaust pipe 88, and the front side of the body 1 is fixedly provided with a control panel 12 for controlling the gas pump 82 to work.

The detection component 6 includes a partition frame 64 and a fixed frame 61 distributed vertically. The partition frame 64 and the fixed frame 61 divide the top of the body 1 into an exhaust chamber 5, a reaction chamber 4 and a steam chamber 3 distributed vertically.
