Device and method for online monitoring quality of safety explosives continuously

Abstract

The invention discloses a device and a method for the online monitoring the quality of safety explosives continuously. The device is composed of a lifting system, a control system, a display system, and an oven. The system uses a single-chip microcomputer as a core control system to control a motor, uses the motor to drive a lead screw to rotate clockwise through fixed wire nuts, so that the weighing system rises, and the counterclockwise rotation decreases, to realize the conversion of an online weighing and a non-weighing. The weighed sample is hung on the hook on a hanger with a hanging basket, and the weighing system is turned on to raise, when the system is working. The weighing system starts to work, and the upper position adopts the Kingview 6.52, and is connected to the computer through the Ethernet communication method. The single-chip microcomputer sends instructions and receives feedback signals of a weighing sensor, and can also set various parameters of the weighing sensor. According to the device and the method for the online monitoring the quality of the safety explosives continuously, the device and the method solve the problem that a real spectrum of real-time quality changes that cannot accurately obtain samples online, realize the human-machine isolation, avoid the problem that the sampler burns and injures the person when sampling at high temperature, shorten the test period, and improve the work efficiency.

Description

technical field [0001] The invention belongs to the field of physical and chemical analysis and testing of explosives, and is mainly applied to a safe continuous on-line monitoring device and method for the quality of explosives in the thermal aging weight loss and volatile matter testing process of explosives. technical background [0002] Storage life is a very critical and important technical index of conventional propellant and explosive products, and its evaluation is a very important work. At present, the evaluation methods for the life of propellant and explosives at home and abroad are mainly the method of mathematical statistics, natural aging and accelerated aging. Because the first two methods require a large sample size and a long test period, the accelerated aging method is currently mainly used for explosives. Explosive Life Estimation. [0003] At present, the determination of moisture and volatile matter in the explosive test method (GJB772.403-89) test is t...

Problems solved by technology

[0004] The current thermal loss method test (GJB770B-2005 505.1) is to measure the mass loss of the sample within a limited time by heating at each specified temperature, and use an oven to conduct a thermal loss / thermal weight loss test with a larger sample size≧5g. Or aging in oven, take out at regular intervals, let cool and weigh, measure the mass loss of sample in the specified time, two kinds of tests are manual operation, process is more loaded down with trivial details and has following shortcoming:

Such methods and devices can only obtain cooled data and have large deviations in the aging research of some samples, and cannot accurately obtain real-time quality changes of samples online, and there are great safety risks in high-temperature sampling, which can easily lead to sample explosions to hurt

[0006] 2. The moisture and volatile content test of the explosive sample is to weigh ≧5g of the sample in a constant weighing bottle, put the weighing bottle containing the sample into a high-temperature oven, dry for a certain period of time, and take out the weighing bottle. Measuring bottles, cooling room temperature and weighing thermogravity, are all manual operations, there is a great safety risk when sampling at high temperature, and it is easy to cause the sample to burn and hurt people
