Abstract

The invention discloses a neutron activation analysis device, and belongs to the field of cement production raw material detection devices. The device includes a shielding assembly, radioactive sources and a detector; the shielding assembly is fixed on a shielding assembly bracket, the radioactive sources are all distributed in a radioactive source cavity, and the detector is arranged in a detector cavity; the radioactive source cavity is positioned at the upper part of the detector cavity, a through cavity is arranged between the radioactive source cavity and the detector cavity, and a conveyor belt carries coal raw materials to pass through the cavity; the radioactive source cavity and the detector cavity are arranged in the shielding assembly, the detector is connected with an analysismeter through wires, and the analysis meter is connected with an operator console. According to the neutron activation analysis device, automatic sampling, making and detection devices are adopted toreplace manpower, sampling efficiency and accuracy are improved, labor intensity and safety risks are lowered, and the problems of quality detection lag, interference caused by human factors and the like are solved; the whole process of quality management is traced dynamically, the problem of adjustment lag is solved, and the more stable process quality is ensured.

Description

technical field [0001] The invention relates to the field of testing equipment for cement production raw materials, in particular, the invention relates to a neutron activation analysis equipment. Background technique [0002] The firing of cement clinker in a cement plant is a complex manufacturing process with many components. In this process, coal can be used as fuel, and the ash in the coal acts as part of the raw material and becomes a part of the clinker to participate in physical and chemical reactions. Therefore, the level of coal ash and its ash composition directly affect the ingredients, and the firing of cement clinker During the process, about 80%-100% of coal ash is mixed into the clinker, and the increase of coal ash changes the ratio of raw materials in the raw meal, causing a vicious circle and making batching difficult. Therefore, cement kilns have high requirements on coal quality. [0003] The cement production process is a continuous and dynamic adjust...
