Abstract
The utility model relates to a device for preventing metal foreign bodies from entering, in particular to a slag vertical mill device for preventing metal foreign bodies from entering, which comprises a transportation belt for transporting slag, a blanking tube and a vertical miller, wherein the blanking tube is connected with the transportation belt, the vertical mill is arranged on the lower end of the blanking tube, the transportation belt is provided with a metal detector, the middle end of the blanking tube is provided with a turning plate valve, and the turning plate valve is connected with a waste slag chamber through a bypass. According to the problem existing in production lines, when the metal detector detects that metal foreign bodies pass through on the raw material transportation belt, the device sends signals to a DCS control system, the DCS control system sends instruction to the turning plate valve again after the DCS control system receives the signals, the turning plate valve acts at once to beat a channel to the position of the bypass, and materials with the metal foreign bodies is discharged to the waste slag chamber through a bypass tube. Therefore, the slag vertical mill device prevents the metal foreign bodies from entering the slag vertical mill and wearing the vertical mill, thereby causing loss.
Description
Technical field
The utility model relates to a kind of anti-metallic foreign body access to plant, and particularly a kind of slag Vertical Mill is prevented the metallic foreign body access to plant.
Background technology
At present, the raw material that is used for COREX slag Vertical Mill is a blast-furnace slag, because smelting technique, transportation and various reasons such as artificial often have iron block, bolt and nut and other big metallic hard things to enter in the COREX Vertical Mill with conveyer belt.COREX Vertical Mill grinding roller if be ground to these metallic foreign bodies, will make receipts power inequality between each grinding roller when milling, and produces vibration, and vibration reaches certain value, and the DCS control system will be sent stop command for protection equipment, and production line shuts down immediately.Once more production line is opened as need, whole flow process needs 30～60 minutes, has influenced output.Long-term big vibration has very big influence to the life-span of surrounding devices, and anxious stop the infringement of the big motor of 3550KW of COREX Vertical Mill also inestimable.
More serious situation be COREX Vertical Mill grinding roller when being ground to metallic foreign body because single-point is stressed, might cause the roller shell wearing layer of grinding roller to peel off, in case wearing layer peels off, this grinding roller roller shell is just scrapped, production line will stop production.Need 40 hours and change roller shell, add the time of the preceding preparation of production line start, the loss that causes is bigger.
Summary of the invention
The technical problems to be solved in the utility model provides a kind ofly can survey metallic foreign body, and stops foreign matter to enter the anti-metallic foreign body access to plant of slag Vertical Mill of slag vertical mill, and this device can be avoided metallic foreign body to enter in the vertical mill and cause damage.
For solving the problems of the technologies described above, described slag Vertical Mill is prevented the metallic foreign body access to plant, the vertical mill 7 that comprises the belt conveyor 1 that transports slag, the tremie pipe 3 that is connected with described belt conveyor 1 and setting and these tremie pipe 3 lower ends, it is characterized in that: on described belt conveyor 1, be provided with a metal detector 2, middle-end at described tremie pipe 3 is provided with a flap valve 4, and described flap valve connects a waste slag chamber 6 by a bypass 5.
Described metal detector 2 all is connected a DCS control system with flap valve 4.
Described DCS control system has function and rapid-action abilities such as signal reception, instruction are sent, Time Calculation.
At the existing problem of production line, the operation principle of the utility model utilization magnetic induction, when COREX slag Vertical Mill moves, when metal detector detects when having metallic foreign body to pass through on the raw material conveyer belt, send signal and give the DCS control system, after the DCS control system receives signal, send instructions again to flap valve through " stand-by period " that has configured (times that the material of band metallic foreign body needs from the metal detector to the flap valve), flap valve moves immediately, passage is beaten to bypass position, the material of band metallic foreign body is discharged in the waste slag chamber by bypass duct, beat to bypass after 2 seconds the DCS control system send instruction once more, flap valve is returned the right way fast, and good material continues to enter in the COREX Vertical Mill.Prevent that like this metallic foreign body from entering in the slag vertical mill, damage machine, cause loss.
Description of drawings
Fig. 1 is the structural representation of the anti-metallic foreign body access to plant of the utility model slag Vertical Mill.
Among the figure: 1. belt conveyor, 2. metal detector, 3. tremie pipe, 4. flap valve, 5. bypass, 6. waste slag chamber, 7. vertical mill.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Slag Vertical Mill is as shown in Figure 1 prevented the metallic foreign body access to plant, the vertical mill 7 that comprises the belt conveyor 1 that transports slag, the tremie pipe 3 that is connected with described belt conveyor 1 and setting and these tremie pipe 3 lower ends, on described belt conveyor 1, be provided with a metal detector 2, middle-end at described tremie pipe 3 is provided with a flap valve 4, and described flap valve connects a waste slag chamber 6 by a bypass 5.
Described metal detector 2 all is connected a DCS control system with flap valve 4.
Described DCS control system has function and rapid-action abilities such as signal reception, instruction are sent, Time Calculation.
At the existing problem of production line, the operation principle of the utility model utilization magnetic induction, when COREX slag Vertical Mill moves, when metal detector detects when having metallic foreign body to pass through on the raw material conveyer belt, send signal and give the DCS control system, after the DCS control system receives signal, send instructions again to flap valve through " stand-by period " that has configured (times that the material of band metallic foreign body needs from the metal detector to the flap valve), flap valve moves immediately, passage is beaten to bypass position, the material of band metallic foreign body is discharged in the waste slag chamber by bypass duct, beat to bypass after 2 seconds the DCS control system send instruction once more, flap valve is returned the right way fast, and good material continues to enter in the COREX Vertical Mill.Prevent that like this metallic foreign body from entering in the slag vertical mill, damage machine, cause loss.
