Description

Cyclone shunt system with anti-blocking function

Technical Field

The utility model belongs to the field of mine production equipment, and particularly relates to a cyclone diversion system with an anti-blocking function.

Background

In mine production, enterprises can grind ores by using a grinder, so that the ores can be crushed. Crushed ore can become fine particles with different diameters, the particles are required to be classified according to the different diameters of the particles, the particles are generally classified into two grades of thickness, and the diameter range of the thickness can be divided according to specific requirements and can also be divided according to industry standards.

At present, crushed ore particles are pumped into a cyclone through a pump to carry out centrifugal gravity classification, the cyclone can classify the ore particles into coarse and fine particle products, coarse particles are discharged from a sand setting outlet of the cyclone, and fine particles are discharged from an overflow outlet of the cyclone. However, since the concentration of the coarse-grained product is high and the granularity is coarse, partial blockage of the sand-setting outlet is easily caused, so that the coarse-grained product which should enter the sand-setting runs into the overflow product, and the classification process cannot be completed as a result, and the influence on the process flow is very large. The prior art is difficult to detect and treat the 'coarse' phenomenon, generally needs to rely on manual naked eyes for observation, has a slow treatment mode and has great actual production difficulty.

By manually detecting the sand setting and ore discharging condition of the cyclone, when the sand setting outlet is partially blocked, the manual reduction of ore discharging water is generally adopted, the ore feeding amount of the cyclone is reduced, or the amount of ore discharging water is reduced, so that the treatment is carried out, the reaction time of the treatment method is long, the influence of the subsequent flow is relatively large, and even the damage of full line shutdown is caused.

The Chinese patent application number is: CN202220817356.4, publication date: the patent literature of 2022, 11 and 28 discloses a gypsum cyclone with an on-line monitoring function, which comprises a slurry separation unit, a density detection unit, a data processing unit, a deep dehydration unit and an overflow collection unit; the slurry separation unit comprises a sand depositing nozzle; the density detection unit comprises an underflow density detection unit; the sand depositing nozzle is communicated with an inlet of the underflow density detection unit; the pulp discharging port of the underflow density detection unit is communicated with the deep dehydration unit; the underflow density detection unit is in communication connection with the data processing unit. According to the utility model, the liquid densimeter is additionally arranged at the bottom flow of the original cyclone, so that the bottom flow density can be detected, the separation effect of the cyclone can be further detected, the blockage of the cyclone is avoided, and the equipment maintenance rate is reduced.

However, although the separation effect of the cyclone can be detected to judge the blockage situation of the cyclone, the follow-up problem caused by blockage is difficult to solve well, meanwhile, the underflow density is directly detected, and the split operation in the working process of the cyclone cannot be ensured to be accurate enough at any time, so that the situation of misjudgment is generated, and the manpower is wasted for inspection.
