Description

Technical Field

[0001] This invention pertains to calibration devices, specifically a portable hydrostatic liquid level calibration device. Background Technology

[0002] In in-situ leaching production, solution accumulation and transportation are key processes. During solution accumulation, the liquid level in the accumulation tank affects the process and safety. Based on years of experience, hydrostatic level gauges are widely used in in-situ leaching uranium mining due to their high cost-effectiveness, low installation requirements, and simple maintenance. Their working principle is P = ρgH + Po, where P is the pressure on the transmitter's liquid-facing surface, ρ is the liquid density, g is the local gravitational acceleration, H is the depth of the transmitter submerged in the liquid, and Po is the atmospheric pressure above the liquid surface. By measuring this pressure, the liquid level can be calculated. However, due to variations in installation location, the parameters of Po and g differ; furthermore, different process parameters at different locations lead to variations in the parameter of ρ. Therefore, standardized indoor calibration is not feasible and on-site verification is necessary. Summary of the Invention

[0013] A portable hydrostatic level gauge calibration device enables convenient, safe, fast, and accurate completion of daily calibration and maintenance work, improving work efficiency and ensuring the standardization and safety of calibration work. The technical solution of this invention includes:

[0014] 1. The present invention provides a portable hydrostatic level gauge calibration device, comprising: a telescopic measuring scale 1, a level contact plate 2, a blind zone distance contact plate 3, a gauge panel 4; and an adjustable bracket 5.

[0015] 2. The meter panel 4 is fixed to the top of the calibration device and includes a level, an alarm device, and a measuring circuit device.

[0016] 3. The liquid level contact plate 2 is fixed to the telescopic measuring scale 1 using a sliding device;

[0017] 4. The blind zone distance contact piece 3 is fixed to the telescopic measuring scale 1 using a sliding device;

[0018] 5. The telescopic measuring ruler 1 is made of PVC or stainless steel, and the smallest scale unit is mm.

[0019] 6. The number of adjustable brackets is 3.

[0020] 7. During on-site inspection, the first step is for the operator to put on personal protective equipment and check whether the portable measuring instrument can work properly;

[0021] 8. The second step is to open the telescopic measuring ruler 1, insert it into the tank to be measured, observe the level, and fix the bracket 5 after the level is centered.

[0022] 9. Third step: Adjust the liquid level contactor 2 until the alarm device indicates that it has contacted the liquid surface, and record the data.

[0023] 10. Fourth step: Adjust the blind spot distance to contact piece 3. Measure the blind spot distance according to the actual situation and record the data.

[0024] 11. Based on the recorded data, the level gauge is calibrated by adjusting the level gauge parameters. Generally, more than 5 sets of data are used to adjust the parameters. The calibration can be completed only after the level gauge is observed to be normal after adjustment.

[0025] The invention is characterized by being portable, allowing for on-site verification, and being easy to operate.

[0026] Under the same type of in-situ leaching mine production conditions, the method of use of this invention can be varied without departing from the spirit of this invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the invention shall be within the scope of protection of this patent.
