Embodiment 1

[0024] Such as Figure 1-6 Said, a device for testing the spontaneous combustion properties and conditions of compressed and packaged goods, including a test thermostat and a pre-treatment compression device for the tested sample, the tested sample is compressed and packed by the compression device and then placed in the thermostat for spontaneous combustion. For testing conditions, the compression device includes a compression cylinder 1, a reinforced test cage 2, a test cage upper cover 3, a briquetting block 4, and a hydraulic-screw composite pressure rod 5.

[0025] The compression cylinder 1 is a detachable rectangular compression cylinder with a lock, including a cylinder body 11 and a fastening baffle 12. The cylinder body 11 is in a rectangular shape, and a locking block 13 is provided on its side. The fastening baffle 12 is set separately from the cylinder body 11. The fastening baffle 12 is provided with a locking hook 14. The fastening baffle 12 is covered on one si...

Abstract

The invention relates to a device for testing spontaneous combustion nature and conditions of compressed and packed goods. The device comprises a constant temperature box for testing and a pretreatment compression device for tested samples, wherein the tested samples are compressed and packed through the compression device and then placed in the constant temperature box for testing the spontaneous combustion nature and conditions, the compression device comprises a compression cylinder, a reinforced testing cage, an upper cover of the testing cage, a pressure block and a hydraulic-spiral compound pressure rod, the reinforced testing cage is arranged in the compression cylinder, the tested samples are loaded into the compression cylinder, then the pressure block is further placed, the compression is performed under the hydraulic-spiral compound pressure rod till all the tested samples are pressed into the reinforced testing cage, then a side plate of the compression box is removed, the upper cover of the testing cage is inserted below a pressure plate and the reinforced testing cage is arranged in the constant temperature box for testing. Compared with the prior art, the range of test objects of spontaneous combustion experiments is expanded, and the device has the advantages of a wide range of applications, safety, reliability and the like.

Description

technical field [0001] The invention relates to a device for testing goods transportation and packaging, in particular to a device for testing the properties and conditions of spontaneous combustion of compressed and packaged goods. Background technique [0002] There is a kind of goods that are usually transported after being compressed and packed (such as cotton, etc.), and their combustion and heat transfer characteristics are very different from those of loose stacking. In the hazard identification during the transportation of goods, the spontaneous combustion test is a very important aspect. , the test method currently used is to determine whether the substance will oxidize and self-heat by exposing the substance to air at a temperature of 100°C, 120°C, or 140°C in a steel mesh container with a side length of 25 mm or 100 mm. If a 100 mm cube sample of a substance exhibits self-heating of the dangerous goods at 140°C, a 25 mm cube sample should be tested at 140°C to det...
