Pipeline material density detection and calibration device

Abstract

The invention relates to a pipeline material density detection and calibration device which comprises a fixed bracket and an instrument frame, wherein a guide rod is fixedly connected to the fixed bracket; a guide block is arranged on the instrument frame, and the guide block is in slide fit with the guide rod; a screw rod is also in screwed joint with the instrument frame, and the other end of the screw rod is rotatably supported on the fixed bracket; a radioactive source is fixedly connected to a rear end plate of the instrument frame; a scintillation counter is fixedly connected to a front end plate corresponding to the rear end plate; openings are correspondingly arranged on the rear end plate and the front end plate of the instrument frame so that the scintillation counter detects the radioactive source through the openings on the rear end plate and the front end plate of the instrument frame; the upper end cover of the instrument frame is provided with at least one elongated jack, and a lower bottom plate of the instrument frame is provided with at least one slot corresponding to the jack; and at least one density board is also positioned between the radioactive source and the scintillation counter in the instrument frame, and all the density boards are respectively inserted into the corresponding jacks and the slots on the instrument frame. The invention has the advantage of simple structure and is accurate for detection.

Description

technical field [0001] The invention relates to a density detection and calibration device for materials, in particular to a density detection and calibration device for materials in pipelines. Background technique [0002] When using pipelines to transport materials, the distribution of materials on the same cross section is usually uneven, so the density is also different. The currently used pipe material density detection equipment can only detect one position of the cross-section of the pipe, and cannot continuously measure the density distribution of the cross-section, and the measurement results are not comprehensive and reliable. In addition, the existing densitometers are only calibrated at the factory, but due to the variety of materials transported by the pipeline, the characteristics of radiation attenuation of different materials may vary greatly, and only relying on the parameter settings of the densitometer manufacturer will cause serious problems. Inaccurate ...
