Development of rotating miniature combustion bomb

Abstract

The invention relates to development and design of a horizontal rotating miniature combustion bomb and a rotation system thereof. The invention consists of two parts, the structure of the combustion bomb and the rotation system. The structure of the combustion bomb has the characteristics of: single head; barrel volume of about 7.30 cm<3>; two temperature measurement thermistors and two thermal resistances on the combustion bomb cover; a mixing blade at the lower part of the bomb body in order to stir a calorimetry agent to flip upwards during rotation and reach quick temperature equilibrium; bomb body made of high temperature high pressure resistant 1Cr18Ni9Ti stainless steel material; platinum or platinum rhodium alloy containing 3-1 / 2% of rhodium on the inner wall of the combustion bomb barrel; and electrode and crucible made of platinum or a platinum rhodium alloy material containing 3-1 / 2 % of rhodium. The rotation system has the characteristics of: rotation of the combustion bomb greater than 360 degrees; three circuits on the combustion bomb (temperature measurement circuit, heating circuit and ignition circuit) connected with the external circuit by using 24 path pure gold contactor collecting ring to ensure smooth circuit; and stepless speed regulation.

Description

technical field [0001] The invention relates to the design and development of a rotating miniature incendiary bomb and its rotating system, which includes two parts, that is, the structure, material and rotating system of the incendiary bomb. Background technique [0002] Since the beginning of the 21st century, with the rapid development of interdisciplinary subjects such as chemistry, life science, new energy and new materials, the demand for thermochemical data is increasing day by day. Into the top secret, there is a greater demand for advanced calorimetry technology, and more and more attention has been paid to the research and development of new integrated calorimeters. Accurate and simple measurement of heat of reaction and heat of transport in a process is the core requirement for the development of calorimetry technology. However, there are several deficiencies in the bomb calorimeters currently on the market: First, the bomb calorimeter is static and the technolog...

AI Technical Summary

Problems solved by technology

However, there are several deficiencies in the bomb calorimeters currently on the market: First, the bomb calorimeter is static and the technology is single, and the reaction system is difficult to quickly reach the chemical equilibrium and thermodynamic equilibrium, and the reaction is not complete and thorough. Therefore, the static bomb is only suitable for measuring The heat of combustion of organic compounds composed of elements such as carbon, hydrogen, oxygen, nitrogen, but not complex complexes containing chlorine, sulfur, phosphorus, boron, and metal elements

The second is that the existing bomb calorimeters, especially the bomb calorimeters used by students in colleges and universities, require a large amount of samples during testing.

For some newly synthesized macromolecular compounds (such as fullerene C 60 and C 70 ), it is often impractical to prepare large quantities of high-purity samples due to the very high cost of preparation and the inaccuracy of measuring small samples with a constant bomb calorimeter

Third, the bomb calorimeters on the market, especially the bomb calorimeters used by students in colleges and universities, do not have a precise constant temperature environment, which will inevitably affect the accuracy and precision of measurement

However, they are not suitable for calibration with electric current; they are also unfavorable for use in Dewar bottles; because the temperature measuring thermistor is not directly in contact with the projectile, the temperature collected often lags behind.
