Abstract

The invention discloses a wireless power supply system and a control method thereof of a drive trolley used for a peripheral drive rake thickener and belongs to the wireless power transmission system and method. The wireless power supply system is composed of a primary side power supply device, a primary side digital control unit, a primary side wireless communication module, a secondary side receiving and changing device, a secondary side digital control unit, a secondary side wireless communication module and the drive trolley. When the wireless power supply system runs, under the control of the primary side digital control unit, constant current in a primary side magnetic energy transmitting coil is realized, then a secondary side pick up voltage is constant, and the drive trolley is regulated by a speeder to run at a constant speed with different loads. The drive trolley is powered through the wireless manner rather than the traditional current collector device, thus, running accidents such as phase loss and short circuit, caused by corrosion and abrasion of the conducting ring and carbon brush and damaged insulation, are avoided, time and cost spent on maintenance are reduced, safety of the rake thickener is improved, and economic benefit of the coal preparation plant is increased.

Description

Technical field [0001] The invention relates to a wireless power supply system and a control method for sedimentation and concentration equipment in a coal preparation plant, in particular to a wireless power supply system and a control method for a transmission trolley for peripheral transmission rake thickeners. Background technique [0002] With the popularization and application of ore dressing and flotation technology, the concentrate slurry contains a large amount of residual flotation reagents, such as collectors, industrial starch, acid and alkali, etc. The above-mentioned various wastewater usually needs to enter the rake thickener for clarification treatment , To further recycle water. [0003] The traditional peripheral drive rake thickener is fixed with a collector device at its central cylinder position, that is, a mechanical slip ring device with a larger diameter, and the power is supplied to the motor through brushes, slip rings and cables laid on the truss. Since ...
