Embodiment Construction
[0008] The examples described below illustrate the present invention in detail.
[0009] The power control system group of the crawler-type mobile magnetic separator of the present invention is composed of a hydraulic system and an electric control system.
[0010] Among them, the hydraulic system includes engine, load sensitive oil pump, travel control system, feeding control system, magnetic separation control system, tailing hydraulic control system (manual control), fine material hydraulic control system (manual control). The travel control system includes a travel proportional valve and a travel proportional amplification board, and the travel proportional amplification board controls the flow of the travel proportional valve. The feeding control system includes a feeding proportional valve and a feeding proportional amplifying board, and the feeding proportional amplifying board controls the flow rate of the feeding proportional valve. The magnetic separation control sy...

The invention discloses a power control system of a crawler-type mobile magnetic separator. The power control system comprises a hydraulic system and an electric control system, wherein the hydraulic system comprises an engine, a walking control system, a feeding control system, a magnetic separation control system and a load sensing oil pump; The electric control system comprises a main control plate, the loading condition of the magnetic separator is calculated by detecting a signal of a pressure sensor of the magnetic separator, and the calculated loading condition of the magnetic separator is compared with the loading of the magnetic separator of a preset value; and by changing the speed ratio control valve of the magnetic separator to change the rotation speed of the magnetic separator, and changing a feeding proportional valve to change the magnetic separator to finally reduce the feeding speed, the actual loading of the magnetic separator and the preset value can achieve relative balance. With the control system provided by the invention, the rotation speed of a magnetic roller can change correspondingly according to the amount of received material, thus improving the ore dressing recovery percentage, achieving the highest work efficiency with least energy consumption, reducing the abrasion of the equipment, as well as saving energy and reducing consumption.
Description
technical field [0001] The invention relates to a power control system of a magnetic separator, in particular to a power control system of a crawler-type mobile magnetic separator. Background technique [0002] At present, the work of the known magnetic separator is given a fixed working speed, and the speed cannot be adjusted during the working process. If you want to change the speed, you can only replace the reducer, and calculate the corresponding speed ratio of the reducer according to the desired speed. In actual operation, it is unrealistic to replace the reducer because of speed regulation, so it is almost impossible to adjust the speed after the magnetic separator is installed and used. When the magnetic separator is working, the rotating speed of the magnetic drum is constant. When the receiving material is large, the iron ore cannot be sorted in time, which will cause serious ore running and low recovery rate; Necessary energy consumption is wasted. Contents o...
