The invention relates to a self-stirring oxygen bomb calorimeter and solves the problems that since an existing oxygen bomb calorimeter stirring paddle is small in influence range, solution temperature cannot reach stabilization quickly, and experiment errors are caused. The self-stirring oxygen bomb calorimeter comprises an outer cylinder and an inner cylinder. The inner cylinder is internally filled with a solution; an oxygen bomb is buried under the solution surface; one internal side of the inner cylinder is provided with a temperature sensor; a motor is arranged above the outer cylinder; a motor shaft is aligned with the vertical axis of the oxygen bomb and vertically outputs power downwards; a stirring paddle is arranged in the solution of the inner cylinder at one side of the oxygen bomb; a rotation shaft of the stirring paddle is arranged vertically; power transmission is realized between the motor shaft and the rotation shaft of the stirring paddle through a two-turning flexible shaft; the flexible shaft is sleeved by a sleeve pipe; the upper end of the sleeve pipe is coaxially arranged with the motor shaft; the lower end of the sleeve pipe is coaxially arranged with the stirring paddle; the outer wall of the upper end of the sleeve pipe is rotatablely supported through a bearing; and the inner wall of the sleeve pipe and the flexible shaft are rotatablely supported through the bearing. When the stirring paddle rotates, the sleeve pipe is driven to rotate simultaneously, so that the temperature of solution in the inner cylinder is allowed to reach stabilization more quickly, and measurement accuracy of the calorimeter is improved.
Description
technical field [0001] The invention relates to a test instrument, in particular to a self-stirring type oxygen bomb calorimeter. Background technique [0002] The calorific value is an important reference and guiding data for biomass energy and resource utilization. According to the different calorific values of biomass, biomass can be classified and effectively utilized to maximize economic, social and environmental benefits. At present, the calorimeter method is an international general calorific value determination method. The experimental method is simple in principle, accurate in results, and simple in equipment. The commonly used calorimeter method generally uses an oxygen bomb calorimeter, and the currently commonly used oxygen bomb calorimeter is generally an ambient constant temperature oxygen bomb calorimeter. A common oxygen bomb calorimeter is provided with an outer cylinder and an inner cylinder, and the heat conduction is blocked by an air barrier between t...
