Embodiment 1

[0033] Such as figure 1 In the shown radioactive waste resin interface measurement device based on the lifting device, the lifting device includes a motor and a transmission frame both arranged on the platform, and a sheave connected to the motor through a rotating shaft, wound on the sheave and rotated with the transmission frame Two steel cables connected. Wherein the application method of the measuring device is mainly completed through the following steps:

[0034] (1) if figure 1 In the shown resin storage tank, the measuring instrument 5 is connected to the density of 7.9g / cm from top to bottom. 3 The carrier body 3 and the density sensor 4 pass through the center of the carrier body and the density sensor, and then the measuring instrument is vertically deep into the resin storage tank; wherein the carrier body is a weight made of a rectangular iron block coated with anti-corrosion material , the measuring instrument is a magnetostrictive displacement sensor;

[003...

Embodiment 2

[0042] The difference from Example 1 is that, as figure 2 The lifting device shown includes springs 20 tied to both ends of the upper surface of the carrier, an electromagnet 18 arranged directly below the carrier and fixed in the bottom of the resin storage tank, and a coil 19 on the electromagnet. The measurement of height consists of the following steps:

[0043] (1) if figure 2 In the shown resin storage tank, the measuring instrument 5 is connected to the density of 7.9g / cm from top to bottom. 3 Carrier 3 and density sensor 4, and pass through the center of the carrier and density sensor, then the measuring instrument is vertically deep into the resin storage tank; wherein the carrier is made of a rectangular sliding pin 17 coated with anti-corrosion material on the outside, so The measuring instrument magnetostrictive displacement sensor;

[0044] (2) Two springs of the same length are attached to both ends of the upper surface of the sliding pin, and each spring is c...

Embodiment 3

[0050] The difference from Example 1 is that the lifting device is located below the resin storage tank, so the measurement of the interface height of the radioactive waste resin includes the following steps:

[0051] (1) if image 3 In the shown resin storage tank, the measuring instrument 5 is connected to the density of 7.9g / cm from top to bottom. 3 The carrier 3 and the density sensor 4 pass through the center of the carrier and the density sensor, and then the measuring instrument is vertically deep into the resin storage tank; wherein the carrier is a support plate made of stainless steel, and the measuring instrument is magnetically induced telescopic displacement sensor;

[0052] (2) A support rod is respectively fixed on both ends of the lower surface of the support plate, and the length of the two support rods is the same, and the other end is fixed on both ends of the balance plate. The lower surface of the balance plate is connected with a telescopic shaft, and th...

Abstract

The invention discloses a radioactive waste resin interface measuring device based on a lifting device and an application method thereof. The measuring device comprises a resin storage tank, a density sensor arranged in the resin storage tank and a material feeding pipe arranged on the resin storage tank and further comprises a measuring instrument vertically stretching into the resin storage tank and in vertical rotating connection with the density sensor, a platform located above the measuring instrument and the lifting device. The measuring device and the method overcome the shortcoming of radioactive waste resin interface height error overbalance caused by the fact that the installation position of a measuring rod cannot be aligned right at a material feeding port, enable the position of the measuring instrument and the density sensor to have no relation with the position and the state of the material feeding pipe and are accurate in measurement.

Description

technical field [0001] The invention relates to a measuring device and its application method, in particular to a lifting device-based radioactive waste resin interface measuring device and its application method. Background technique [0002] Radioactive waste resin is a solid nuclear waste with a long half-life, with a density of 1.07-1.12 g / cm 3 , the density difference with water is very small, and the average individual diameter is 0.7mm. It is stored in water for a long time, and it will be cured after further decay. Because of the process requirements, whether it is storage or treatment, the amount of resin and water must be adjusted. Precise measurements for safety. [0003] The measurement device in the public literature at this stage is to pass the density sensor through the measuring rod, so that the density sensor floats on the radioactive waste resin interface, to identify two different interfaces, and then use the position sensor to display the position of the...
