First, upwards endfeed mouth 3 adds ore pulp, when (can being 30 seconds, 1 minute after the schedule time 1,2 minutes, be preferably 30 seconds herein), material induction module upper end charging aperture 3 does not sense material process, then this induction end value is converted into digital signaling zero 01 and is passed to PLC; (can be 30 seconds, 1 minute, 2 minutes, be preferably 30 seconds herein) after the schedule time 2, lower end charging aperture 3 sense material process, then this induction end value is converted into digital signaling zero 02 and is passed to PLC; Concentration detection module detects the mineral concentration C at mine mouth 4 place
ore deposit, and be converted into digital signal 101 and be passed to PLC;
PLC receives digital signaling zero 01 respectively, transmits executive signal 201 to valve switch module; Receive digital signaling zero 02, transmit executive signal 202 to valve switch module; In order to avoid ore pulp in refining process because of vibration from charging aperture 3 flow out phenomenon, avoid ore pulp to splash ground and be inconvenient to clear up;
Receive digital signal 101, transmit executive signal 301 to display module; Object is the information providing mineral concentration to user;
Work as C
ore deposit< predetermined value 1, then transmit executive signal 302 to motor drive module, meanwhile, transmits executive signal 401 to vibration-variable frequency module; As predetermined value 1<C
ore deposit< predetermined value 2, then transmit executive signal 303 to motor drive module, meanwhile, transmits executive signal 402 to vibration-variable frequency module; As predetermined value 2<C
ore deposit< predetermined value 3, then transmit executive signal 304 to motor drive module, meanwhile, transmits executive signal 403 to vibration-variable frequency module; Work as C
ore deposit> predetermined value 3, then transmit executive signal 305 to motor drive module, meanwhile, transmits executive signal 404 to vibration-variable frequency module; If mineral concentration lower than predetermined value 1, then illustrates
Illustrate that magnetic separator selects degree high to the concentrate of ore pulp, electric machine rotation is too fast, needs to reduce chosen level, so the rotating speed of the motor that needs to slow down, the concentration going out mine mouth is lower, and the concentrate in magnetic system is fewer, then vibrating device vibration frequency is lower.
PLC transmits executive signal 501 every the schedule time 3 to blowdown module; The deposit buildup produced due to ore pulp is in the lower floor of housing 1, and the time can block lower end charging aperture 3 once long, so need timing cleaning;
Valve switch module receives executive signal 201, valve-off; Receive executive signal 202, Open valve; Display module receives executive signal 301, and is shown on display screen by mineral concentration value; Motor drive module receives executive signal 302, and motor 2 is adjusted to desired speed N1; Receive executive signal 303, motor 2 is adjusted to desired speed N2; Receive executive signal 304, motor 2 is adjusted to desired speed N3; Receive executive signal 304, motor 2 is adjusted to desired speed N4; Vibration-variable frequency module receives executive signal 401, and the vibration frequency of vibrating device 5 is adjusted to preset frequency f1; Vibration-variable frequency module receives executive signal 402, and the vibration frequency of vibrating device 5 is adjusted to preset frequency f2; Vibration-variable frequency module receives executive signal 403, and the vibration frequency of vibrating device 5 is adjusted to preset frequency f3; Vibration-variable frequency module receives executive signal 404, and the vibration frequency of vibrating device 5 is adjusted to preset frequency f4; Blowdown module receives executive signal 501, now shower nozzle moves to vertical direction 15 degree of places and sprays water to housing 1 bottom surface, after the schedule time 4, now shower nozzle moves to vertical direction 30 degree of places and sprays water to housing 1 bottom surface, by that analogy, until shower nozzle moves to vertical direction 60 degree of places sprays water to housing 1 bottom surface.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
