Description
Technical Field
The invention belongs to the technical field of ore pulp metering and fluid metering calibration, and particularly relates to an ore pulp calibration device.
Background
At present, the ore pulp metering is mainly performed by using a flowmeter, the flowmeter is mainly an ultrasonic flowmeter, the flowmeter is divided into a time difference type flowmeter and a Doppler type flowmeter according to a measurement principle, and the ultrasonic flowmeter is designed based on the principle that the speed of ultrasonic wave propagation in a flowing medium is equal to the geometric sum of the average flow velocity of the measured medium and the speed of the acoustic wave. It also reflects the flow magnitude from the measured flow rate. The time difference type ultrasonic flowmeter manufactured by using the time difference type principle is widely paid attention to and used in recent years, and is the ultrasonic flowmeter most used by enterprises and public institutions at present. The ultrasonic Doppler flowmeter manufactured by Doppler effect is mainly used for measuring medium with certain suspended particles or bubble medium, has certain limitation in use, but solves the problem that the time difference type ultrasonic flowmeter can only measure single clear fluid, and is also considered as an ideal instrument for non-contact measurement of two-phase flow. The ultrasonic flow meters currently in use have the following drawbacks: 1) The temperature measuring range of the ultrasonic flowmeter is not high, and generally only fluid with the temperature lower than 200 ℃ can be measured, so that the anti-interference capability is poor; 2) Is easy to be interfered by ultrasonic noise mixed by bubbles, scaling, pumps and other sound sources, and influences the measurement accuracy; 3) The straight pipe section has strict requirements of front 20D and rear 5D, otherwise, the discreteness is poor, and the measurement precision is low; 4) The uncertainty of installation can bring larger error to flow measurement; 5) The measuring pipeline can seriously influence the measuring accuracy due to scaling, so that obvious measuring errors are brought, even when the measuring pipeline is serious, the instrument has no flow display, the reliability and the precision level are not high (generally about 1.5-2.5 levels), the repeatability is poor, and the service life is short (generally the precision can only be guaranteed for one year); 6) The ultrasonic flowmeter determines the volume flow by measuring the fluid velocity, the mass flow of the fluid is measured, the mass flow is measured by multiplying the volume flow by the manually set density, when the fluid temperature changes, the fluid density changes, the manually set density value cannot guarantee the accuracy of the mass flow. Only when the fluid velocity is measured, the fluid density is measured, and the actual mass flow value can be obtained through calculation. This results in very high costs and very inconvenient replacement, since the field often encounters various problems during installation, which makes field maintenance difficult, which is time consuming, laborious, and very prone to affecting production, especially when the pressure on the field is high, and less prone to maintenance. Therefore, there is a need in the art for a slurry calibration method or device that changes the current metering method to facilitate rapid on-site slurry calculation.
