Embodiment Construction

[0021] The structure and usage measurement method of the present invention are illustrated in conjunction with the accompanying drawings.

[0022] A mobile measuring instrument for measuring the material level in a storage bin, such as figure 1 shown.

[0023] In the shielding container 1, a detector 2 is installed on one side, and a cable hole 6 is opened at the position behind the detector 2. On the other side of the shielding container 1 there is an oblique fan-shaped collimation hole 3 . At the back of the collimating hole 3, a rotating body 4 is installed, and the rotation of the rotating body can be realized manually or controlled by electric automation. On one side of the rotating body 4, a gamma ray source 5 is installed. The type and activity of the appropriate gamma-ray source can be selected according to the volume of the storage bin, the material and thickness of the bin wall, and the properties of the contents of the bin. If an isotopic radioactive source is c...

Abstract

The invention discloses a mobile measuring instrument and a measuring method of the material level in a storage warehouse. The rear part of a collimating hole of a shielding container is equipped with a gamma-ray source rotating block, a detector is fixed on the shielding container, a lifting device is installed on the shielding container, and a transmission signal cable of the detector is connected with a host. The method for measuring the material level in the storage warehouse is as follows: the shielding container moves form the bottom part of the storage warehouse to the top part of the storage warehouse, the host constructs a planar curve graph according to the counting rate transmitted by the detector in real time, wherein, the horizontal axis is the counting rate, and the vertical axis is the movable height of the shielding container, the state and the property of the material in the storage warehouse are analyzed and judged according to the curve. The measuring instrument has simple structure and easy operation, can be installed on a movable dolly, or is broken into several blocks to be reassembled in different places, thereby measuring different storage warehouses. An instrument of measuring equipment can measure a plurality of storage warehouses, thereby saving a great amount of cost and having high measuring efficiency.

Description

Technical field: [0001] The invention relates to a measuring instrument, in particular to a measuring instrument for the height of materials in a non-contact storage bin. technical background: [0002] In cement, chemical industry, metallurgy and many other fields, large storage bins are the best choice for storing spare materials. However, large storage bins are bulky, and some even need to be airtight, so it is very cumbersome to monitor the storage situation in the bin manually. At present, there are many kinds of measuring principles and methods of level gauges, but they are all fixed, that is, once installed, they can only be placed at this point for a long time. These conventional transmission-type fixed-point measurements can only respond to this fixed point. It is impossible to measure the material level height of multiple storage bins and the overall or partial density change in the same storage bin. For some storage bins that do not need to be monitored in real t...
