When the telescopic part 108 does not pull out the magnetic bar 1071 from the iron removal device 10, the switching valve 111 is adjusted to divert to the discharge port 102 and block the impurity discharge port 1092, so that the material is discharged from the discharge port 102. When the telescopic part 108 pulls out the magnetic bar 1071 from the iron removal device 10, the switching valve 111 is adjusted to divert to the impurity discharge port 1092 and block the space leading to the discharge port 102, so that the iron-containing impurities are discharged from the impurity discharge port 1092.

When the material enters the hopper 100 through the feeding port 101, the gas permeable cap 103 can balance the internal and external air pressure of the hopper 100, and can also discharge the dust in the hopper 100, thereby reducing the probability of dust accumulation in the material causing blockage in the hopper 100, ensuring the safety of the hopper 100 and improving the stability of the hopper 100.

[0043] Please refer again to Figure 1 and Figure 2 , the working principle of the iron removal device 10 will be described below:

[0044] Before the material enters the bin 100, the adjusting switch valve 111 is closed to close the impurity discharge outlet 1092, and the integrated plate 1072 is driven by the telescopic part 108 to insert the magnetic rod 1071 into the first group of isolation sleeves 1061 and the second group of isolation sleeves 1062. After the magnetic rod 1071 is inserted into the first group of isolation sleeves 1061 and the second group of isolation sleeves 1062, the discharge outlet 102 is closed and the feeding inlet 101 is opened, and the material enters the bin 100 from the feeding inlet 101 to realize the storage function of the material. The weight of the material is obtained by the weighing assembly 112, and the material level is confirmed by the material level observation port 113. When the weight of the material and the material level reach the preset value, the impurity discharge outlet 1092 is kept in the closed state, the discharge outlet 102 is opened, and the difference between the feeding speed and the discharging speed of the material is adjusted within the preset range by the feeding control assembly 101a and the discharging control assembly 102a, so that the material level in the iron removal equipment 10 is stably controlled within the preset requirement range, and the material flows in the bin 100 to the discharge outlet 102, and the flow speed is kept within the preset range, for example, the flow speed is less than 1 cm / min. At the same time, the magnetic rod 1071 inserted into the first group of isolation sleeves 1061 and the second group of isolation sleeves 1062 adsorbs the iron-containing impurities in the flowing material. The sieved material is discharged from the discharge outlet 102 and transferred to the next process. In this way, the iron removal function of the iron removal equipment 10 is realized.

[0045] When the material continuously enters the iron removal equipment 10 for a period of time and needs to be cleaned, the feeding inlet 101 is closed, the impurity discharge outlet 1092 is kept in the closed state, the material in the iron removal equipment 10 is discharged in a preset state, and when the weighing assembly 112 and the material level observation port 113 reach the preset range, it is judged that the material in the iron removal equipment 10 is completely discharged. After the material is completely discharged, the adjusting switch valve 111 is opened to open the impurity discharge outlet 1092, the magnetic rod 1071 is pulled out of the first group of isolation sleeves 1061 and the second group of isolation sleeves 1062 by the telescopic part 108 driving the integrated plate 1072, the iron-containing impurities adsorbed on the inside of the iron removal equipment 10 and the first group of isolation sleeves 1061 and the second group of isolation sleeves 1062 are vibrated and fallen off by the knocking hammer 1091 knocking the bin 100, and are discharged through the impurity discharge outlet 1092. After the iron-containing impurities are discharged, the iron removal equipment 10 is purged by the purging member 110, and the residual iron-containing impurities are discharged through the impurity discharge outlet 1092. In this way, the iron removal function of the iron removal equipment 10 is realized. Related technical personnel can preset the program to realize the automatic circulation of the iron removal function and the iron removal function of the iron removal equipment 10.
