Problems solved by technology

Although it can also run, but the measurement system has many links, the maintenance workload is heavy, and the time interval between up and down time is more than 10 minutes. In fact, online real-time detection cannot be well realized. If the slurry conveying pipe is longer, the time will be longer and the real-time performance Poor, resulting in poor simultaneity of the dosing dose, and frequent sampling for ore slurry, valves and pipes are easy to jam

Embodiment Construction

[0024] The invention measures the concentration of the ore pulp continuously flowing upwards and downwards. Sampling from the supernatant overflow pool of the spiral classifier or hydrocyclone after grinding in the concentrator can also be taken from other similar slurry process pools. The ore slurry flows through the measuring tube continuously from top to bottom, so the measuring device needs a natural height difference of about 1.5m, which is easy to meet in the concentrator. Carry out dynamic weighing and slurry level height measurement for small container tanks. When the dry ore density is basically unchanged, the amount of slurry entering and exiting is equal, and the level of slurry level in the tank remains unchanged, the weighed weight (excluding the weight of the tank body) ) to the pulp volume in the corresponding tank (the height of the pulp surface is measured accordingly) is the pulp density, and the pulp concentration is obtained by using the following formula (...

Abstract

The invention discloses a small weighing type continuous pulp flow weight concentration measurement device. The device includes a vertically arranged forked pipe within a wear resistant inner surface. One branch top of the forked pipe is communicated with a siphon that can suck pulp from an overflow pulp tank and can flush water into the forked pipe when the measurement device stops measuring. A pulp discharge valve is installed at the bottom end of the forked pipe. The non-forked end of the forked pipe passes through a weighing system, which can weigh the total weight G of the forked pipe and the pulp fluid therein. The measurement device provided by the invention basically avoids pulp blockage, the valve can be used for a long term and is difficult to wear and damage, and stable measurement can be realized. Because of no use of radioisotope, full pipe and bubble problems at instrument installation positions in a dressing plant are unnecessary to consider, bubbles can also escape from the liquid level of a first tubular container involved in the invention, staff of different types of work can perform repairing and maintenance at ease, and have no need to consider whether radioactivity exists nearby.

Description

technical field [0001] The invention relates to the field of real-time measurement of slurry flow concentration of industrial materials, in particular to a small weighing type continuous slurry flow weight concentration measurement device. Background technique [0002] In the mine filling system of metallurgy, the grinding and floating system of the mineral processing plant, the slurry system of the chemical plant, the slurry system of the building material plant, the black liquor system of the paper mill, the sewage treatment system, and the modern 3D material spraying manufacturing system, the concentration of the material slurry flow is Core parameters for real-time control in the process industry. In the slurry, the slurry flow concentration of the material is generally measured by weight concentration, which basically reflects the quantity and quality of the material processed in the process industry. Therefore, its accurate measurement and real-time stable control are ...
