Automatic control system and method of powder concentrator

Abstract

The invention discloses an automatic control system and method of a powder concentrator. The automatic control system comprises a feeding detection module, a rotation speed detection module, an air speed detection module, a discharge detection module, a PLC, a feeding adjusting module, a rotation speed adjusting module, an air speed adjusting module and a discharge adjusting module. The automatic control system is used for detecting the collection flow rate of fine powder, detecting and adjusting the material feeding speed, the rotation speed of a transmission part, and the intake speed and exhaust speed of recirculating air in real time. By the adoption of the automatic control system and method of the powder concentrator, jamming and unsmooth feeding of a feed inlet can be effectively prevented; the powder concentrator is monitored in real time, so that the system safety and reliability are improved; and possible faults are predicted, and meanwhile emergency operations are realized in case of faults.

Description

technical field [0001] The invention relates to the field of control systems, in particular to an automatic control system and method for a powder classifier. Background technique [0002] In the mining process of the mine, a series of operations such as crushing, crushing, screening and screening are required for the ore. The grade of the material is stored in grades. At present, during the screening and classification of materials, the residence time of materials in the sorting equipment is short, and the fine powder and ultrafine powder with extremely small particle size are not easy to be collected, which leads to inaccurate classification, making the particle size less than 50 μm The powder is not easy to be collected, which not only causes air and environmental pollution, but also causes a waste of resources. In addition, in the current material screening, due to the accumulation of materials, the screening range of materials of the same level is extremely unstable, ...

Problems solved by technology

At present, during the screening and classification of materials, the residence time of materials in the sorting equipment is short, and the fine powder and ultrafine powder with extremely small particle size are not easy to be collected, which leads to inaccurate classification, making the particle size less than 50 μm The powder is not easy to be collected, which not only causes air and environmental pollution, but also causes a waste of resources

In addition, in the current material screening, due to the accumulation of materials, the screening range of the same level of materials is extremely unstable, and the fluctuation is relatively obvious, which seriously affects the efficiency of material sorting, resulting in low efficiency

[0003] And because the speed of putting in the materials is uncertain, if the speed of putting in the materials is too fast, it may cause all the materials to be blocked at the feeding port, and any material cannot enter the feeding port. If the materials are put in too slowly, it may cause energy loss. waste; if the speed of the transmission equipment is too fast, it will bring safety problems to the entire powder separator and its system; if the circulating air leaks in the cyclone, its efficiency will be reduced. If the inlet or outlet of the circulating air is blocked, Then the wind speed in the cyclone will be seriously unbalanced, which may bring safety problems to the system; if the difference between the feed speed and the flow rate of fine powder collection is too small, it may reduce the operating efficiency of the powder classifier, and seriously , may cause the powder separator to operate unsafely
