Abstract

The invention discloses a controllable neutron source mechanism for coal component analysis. The controllable neutron source mechanism comprises a neutron tube assembly, a power supply assembly, a control assembly and a communication assembly; the neutron tube assembly comprises a neutron tube, a neutron tube sleeve, a neutron moderating body and a protective body; the power supply assembly comprises a power supply cabinet, a memory power supply module, an ion source power supply module and an accelerating pole power supply module; the control assembly comprises a neutron detector, a power supply control unit, a neutron tube start-stop module, a neutron yield control module and a neutron tube fault automatic diagnosis and protection module. All components of the mechanism are integrated into a whole, and the mechanism is applied to a controllable neutron source movable type coal component rapid detection device; neutron emission is automatically controlled; the neutron tube is turned off in a non-working period; and device movement and radioactive source management are facilitated; by automatically adjusting the current of a memory and the voltage of an accelerating electrode, theneutron yield is stabilized, and the precision and stability of coal component detection can be improved.

Description

technical field [0001] The invention relates to a controllable neutron source mechanism for coal component analysis, belonging to the technical field of neutron generators. Specifically, it relates to a controllable neutron source mechanism and a control method used in a rapid detection device for incoming coal composition of coal transported by cars and trains. Background technique [0002] Prompt Gamma Neutron Activation Analysis (PGNAA) is an effective method for online detection of elemental composition in bulk coal. Most of the technical products at home and abroad are cross-belt coal composition online detection equipment, which either directly detect the raw coal on the main conveyor belt, or detect the raw coal on the auxiliary belt after mechanical sampling. For a large amount of coal transported into the factory by car or train, it is still sampled by mechanical sampling machines and tested in a laboratory, and the coal quality data cannot be obtained in time, and...
