From Fig. 2, Fig. 3 and Fig. 4 as can be known, as a kind of optimal way of the present utility model, sideslip can be housed on the belt in fragmentation and the conveying device detect and automatic deviation rectifying device 10: sideslip promptly all is housed on the belt 12,13 of the fragmentation of broken workshop section and conveying device in thick detect and automatic deviation rectifying device 10; Sideslip is housed on the belt 22 of the fragmentation of fine-crushing department and conveying device to be detected and automatic deviation rectifying device 10; Sideslip is housed on the belt 32 of the fragmentation of break section and conveying device to be detected and automatic deviation rectifying device 10.
As can be seen from Figure 5, sideslip detects and comprises the sideslip cam baffle plate 7 on the belt side, the correction activity carrying roller 8 that links to each other with connecting rod 6 with automatic deviation rectifying device 10, and cam baffle plate 7 passes from connecting rod 6.
System of the present utility model: (1) has realized that iron ore dressing produces thick in broken workshop section broken and the robotization control of carrying: the lump ore in the raw ore groove 11 as shown in Figure 2 is after belt conveyor 12 size degradation in the boulder crusher 16 becomes the piece grain of granularity less than 85mm, becoming granularity through belt conveyor 13 size degradation in the intermediate crusher 17 again is buffer memory in the ore storage bin 21 during the piece grain of 15mm～60mm enters, and waits for entering next procedure.DCS or PLC system are by the state of the switch 9 that skids on the driven voller that detects belt feeder 14,15; be normally or owe speed in order to the speed of judging belt feeder 14,15; thereby the feed and the material reducing of control ore avoid streams to send the frequent unlatching of running material and equipment.Simultaneously, DCS or PLC system detect when the electric current of intermediate crusher 17 surpasses 300A and continues above 10 seconds according to the operating load of intermediate crusher 17, and belt feeder 15 is out of service; When the electric current of intermediate crusher 17 drops to 150A when following, belt feeder 15 starts automatically, recovers to give the ore deposit; realize " transship automatic material reducing, underloading automatic charging " control, avoided intermediate crusher to transship stuck shutdown; improve operational efficiency, realize broken and streams in thick send production steadily.In the time of in the process that belt is carried, if belt 12,13 sideslips, sideslip cam baffle plate 7 will be pushed in its side, and sideslip cam baffle plate 7 drives correction activity carrying roller 8 by connecting rod 6 and moves, and belt conveyor is set back, and realizes automatic deviation correction.
(2) realized the broken of fine-crushing department that iron ore dressing is produced and the robotization control of carrying: the fritter ore in the middle ore storage bin 21 as shown in Figure 3 is after belt conveyor 22 size degradation in the fine crusher 26 becomes the piece grain of granularity less than 12mm, enter abrasive dust ore storage bin 31 buffer memorys, wait for entering next procedure.DCS or PLC system are normally or owe speed in order to the speed of judging belt feeder 24, thereby the feed and the material reducing of control ore avoid streams to send the frequent unlatching of running material and opertaing device by the state of the switch 9 that skids on the driven voller that detects belt feeder 24.Simultaneously, when the electric current of DCS or PLC system detection fine crusher 26 surpassed 90A and continues above 10 seconds, belt feeder 24 was out of service; When the electric current of fine crusher 26 drops to 100A when following, belt feeder 24 starts automatically, recovers feed; realize " transship automatic material reducing, underloading automatic charging " control, avoid comminutor to transship stuck shutdown; improve operational efficiency, realizes that in small, broken bits and streams send the steady of production.In the time of in the process that belt is carried, if belt conveyor 22 sideslips, sideslip cam baffle plate 7 will be pushed in its side, and sideslip cam baffle plate 7 drives correction activity carrying roller 8 by connecting rod 6 and moves, and belt conveyor is set back, and realizes automatic deviation correction.
(3) realized the broken of break section that iron ore dressing is produced and the robotization control of carrying: the fritter ore in the abrasive dust ore storage bin 31 as shown in Figure 4 is after belt conveyor 32 size degradation in the comminutor 36 becomes the powder of granularity less than 6mm, enter in the fine ore bin 37, wait to sell away as finished product.The electric current that DCS or PLC system detect comminutor 36 surpasses 170A and lasting above 10 seconds, and belt feeder 34 is out of service; When the electric current of comminutor 36 drops to 105A when following, belt feeder 34 starts automatically, recovers to give mineral aggregate; realize " transship automatic material reducing, underloading automatic charging " control, avoid comminutor to transship stuck shutdown; improve operational efficiency, realization is pulverized and streams is sent the steady of production.In the time of in the process that belt is carried, if belt conveyor 32 sideslips, sideslip cam baffle plate 7 will be pushed in its side, and sideslip cam baffle plate 7 drives correction activity carrying roller 8 by connecting rod 6 and moves, and belt conveyor is set back, and realizes automatic deviation correction.
System of the present utility model has all realized the whole-course automation control of DCS or PLC on the conveying equipment of each workshop section.Because broken production processing power broken, in small, broken bits, that pulverize these three workshop sections is inconsistent in iron ore material thick, so three workshop sections independently realize Automatic Control separately, it is opened, stops mainly according to bin-level.
DCS or PLC system detect and carry out the action control procedure and be summarized as follows:
1. DCS or PLC system detect slipping state broken in thick, the fine-crushing department belt feeder, be normally or owe speed in order to the speed of judging this belt feeder, thereby the feed and the material reducing of control ore avoid streams to send the frequent unlatching of running material and opertaing device;
2. DCS or PLC system detect each disintegrating machine electric current, realize " transship automatic material reducing, underloading automatic charging " control function, prevent disintegrating machine stuck, thereby protected each disintegrating machine;
3.
