Problems solved by technology

[0004] However, there are defects in the above two methods of measuring coal bulk density: during the measurement process, the coal needs to be manually loaded into the container by the staff, which increases the work intensity of the staff, and the process of loading and unloading coal takes a long time, resulting in The entire measurement cycle takes a long time, and the tightness of the coal will change during the process of loading the coal into the container, resulting in errors in the measurement of the bulk density of the coal, resulting in low measurement accuracy

Abstract

The embodiment of the invention discloses a nucleon detection device for bulk density of coal. The device comprises a box, a shelter arranged in the box, a motor arranged in the box, an inner rotor, a gamma radioactive source and a gamma detector, wherein a cavity, a through hole and an alignment hole are formed in the shelter; the inner rotor is arranged in the cavity of the shelter, and is provided with a groove and a spindle; one end of the spindle penetrates through the through hole on the shelter and is connected with a bearing of the motor; the gamma radioactive source is arranged in the groove; and the gamma detector is arranged in the box and is connected with a control circuit. When the nucleon detection device detects the bulk density of coal, the coal is not required to be loaded and unloaded, the working strength of workers is reduced, the tightness of the coal cannot be changed due to man-made reasons, deviation in the process of measuring the bulk density of the coal is avoided, and the measurement accuracy is further improved; meanwhile, in the detection process, the time consumption is low and a measurement period is shortened.

Description

technical field [0001] The invention belongs to the technical field of density detection, in particular to a nuclear coal bulk density detection device. Background technique [0002] The density of coal is an important parameter for calculating coal storage. In large coal yards, it is necessary to measure the density of different types of coal separately. [0003] At present, there are mainly two methods for measuring the bulk density of coal: 1. The method of measuring the bulk density of coal in a small container. Put the coal into a small container with a volume of 200 liters, weigh the small container filled with coal, and remove the Calculate the density of coal after the weight of the container; 2. The method of measuring the bulk density of coal in a large container, load the coal into a truck with a load of more than 3 tons, weigh the truck full of coal, and calculate the density of coal after removing the weight of the truck. These two methods of measuring the bul...
