Mineral slurry flux on-line detecting device and multi-parameter on-line detecting integrated system

Abstract

The invention provides an online detection device for the pulp flow rate and a multi-parameter online detection integration system, which comprise a pulp container which has a feed port and a discharge port and is arranged on a support through a, weighing cell, a pulp flow rate detection device which is provided with a soft connector at the discharge port, and/or a pulp density measuring device, a pulp grain size measuring device and a pulp grade measuring device. The online detection device for the pulp flow rate and a multi-parameter online detection integration system can not only measure any single index of the flow rate, density, grain size and grade of the pulp according to requirements, but also simultaneously measure two or above two or even all of the indexes with high measuring accuracy, good stability and reliability. The online detection device for the pulp flow rate and a multi-parameter online detection integration system also have the advantages of simple structure, high working efficiency, low labor intensity, wide application range, etc., thereby being capable of providing the highly reliable flow rate, density, grain size and grade control parameters for liquid products to ensure product quality, reduce cost and improve working efficiency, and providing a highly guaranteed measuring device and system for full automatic control.

Description

technical field [0001] The invention relates to a detection device, in particular to a device and system for measuring pulp flow, concentration, particle size and mineral grade by weighing. Background technique [0002] The pulp flow rate is an important indicator in the mineral processing process, and its measurement accuracy will directly affect the automatic control of the mineral processing process. As far as the current pulp flow detection devices are concerned, there are contact electromagnetic flowmeters, vortex flowmeters, turbine flowmeters and target flowmeters. The probes of the contact flowmeter are all in direct contact with the pulp, so they are often worn, polluted, or blocked, which affects the measurement accuracy and service life, or even makes it impossible to measure. In addition, there are non-contact ultrasonic flowmeters, laser flowmeters, etc. These flowmeters are susceptible to air bubbles, noise, and particle size of the pulp generated when the pul...

AI Technical Summary

Problems solved by technology

[0003] The measurement accuracy is affected by the interference of other factors, and there are also problems such as complex structure and high cost, which make it difficult to meet the requirements of automatic control

[0004] As far as the currently used liquid density measuring instruments are concerned, most of them can only measure the liquid density in a static state, and it is difficult to accurately measure the density of a flowing liquid. For products such as coal slurry, if the density measurement is inaccurate, it will not only reduce the quality of the product, but also affect the smooth progress of the subsequent process, and even increase the production cost

[0005] As far as the current measurement of the size of pulp particles, that is, the pulp particle size measuring instrument, is mainly done through complicated manual operations such as sampling, screening, and measurement, it not only has low work efficiency, high labor intensity, and low measurement accuracy, but also cannot be carried out online.
