Examples
The working principle of the device for automatically cleaning the blockage of the powder ore bin is as follows: the control device is used as a control center and can receive feedback and output control information; the water source in the workshop is connected with the water supply pipe and communicated to the water supply tank, the water level meter and the electric valve of the water pipe are used for controlling the liquid level of the water supply tank through communication connection with the control device, and the liquid level of the water supply tank can be kept in a relatively full state all the time. Assuming that the height of the water supply tank is 2.5m, the upper limit value of the liquid level of the water supply level gauge may be set to 2m, and the lower limit value may be set to 1 m. If when the liquid level numerical value of monitoring when the water supply level gauge is less than 1m, can trigger controlling means and send control signal, open the water pipe electrically operated valve, supply water, when the liquid level numerical value of monitoring when the water supply level gauge reachs 2m, close the water pipe electrically operated valve, stop supplying water.
And (3) when the powder ore bin is smooth in discharging, adjusting the ore feeding amount of the next step of ore grinding through the frequency of the disk feeder, wherein the ore feeding amount can reach 180t/h when the frequency is the highest. Similarly, the bin height of the powder ore bin is assumed to be 9.5m, namely, the level meter of the powder ore bin displays a monitoring value of 9.5m when the bin is empty; when the monitoring value of the level meter of the powder ore bin is 9.5m or 8m, the frequency of the disc feeder is 49.5Hz, and the ore amount monitored by the electronic conveyor belt scale is 120t/h, the control device can judge that no blockage exists in the powder ore bin, the ore powder in the powder ore bin can normally come out to the disc feeder, and the disc feeder conveys the ore powder to the conveyor belt to enter the next processing procedure; if the monitoring value of the level gauge of the powder ore bin is less than 8m, the control device can judge that the powder ore bin is hardened or caked. When the level meter monitoring value of the powder ore bin is less than 8m, the frequency of the disk feeder is more than 49.5Hz, and the ore amount monitored by the electronic conveyor belt scale is less than 120t/h, the control device can judge that the powder ore bin is blocked, send a control signal and trigger the water supply pump to be started to supply water. And flushing the side wall of the fine ore bin by utilizing pressurized water flow. When the ore amount monitored by the electronic conveyor belt scale is more than 150t/h, the water supply pump is triggered to be closed, and the washing of the fine ore bin is completed; the machine operates normally and the ore powder is conveyed to the next working procedure processing place.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
