Abstract
The invention provides a method for controlling material discharging of a material bin of a sintering and burdening system. The method comprises the following steps of: acquiring a working state of the sintering and burdening system; if the working state is a restarting state, controlling the material bin to discharge materials according to a preset delay time after the material bin of the sintering and burdening system is started; and if the working state is a stopped state, controlling the material bin to discharge the materials immediately after the material bin of the sintering and burdening system is started. Furthermore, the invention also provides a device for controlling the material discharging of the material bin. According to the embodiment of the invention, the working state of the system is acquired, so that the material bin can be controlled to discharge the materials according to the preset delay time or discharge the materials immediately after the system is started to work on the basis of different working states; and therefore, a phenomenon of the absence of materials gathered on a mixed belt is avoided. An aim of avoiding waste materials caused by the material absence phenomenon during burdening is fulfilled; the quality of the sintering process is improved; and the energy consumption is reduced.
Description
Technical field
The present invention relates to the control technology field, particularly relate to a kind of bin blanking control method and device of sintered material system.
Background technology
As shown in Figure 1, system architecture schematic diagram for the sintered material system, wherein, the feed bin group can comprise a plurality of feed bins 10, a kind of material of the interior splendid attire of each feed bin 10 (material can comprise the material etc. that mixes ore deposit, limestone, returns mine and mix), be provided with at least one blanking disk 11 below feed bin, the exit of each blanking disk also arranges respectively a blanking belt conveyer scale 12, and blanking disk 11 and the blanking belt conveyer scale 12 corresponding with it form blanking row.When the sintered material system works, each feed bin is default delay time according to self respectively, the material of splendid attire in feed bin is dumped into to the blanking disk by a certain percentage, and then by the outlet of blanking disk, material is dumped into to corresponding blanking belt conveyer scale, finally by the blanking belt conveyer scale, material is sent to and mixes belt 20.
Mix belt for gathering the material of each feed bin unloading, and move according to the direction of diagram f, mixed material is sent to the mixer (not shown), after twice mixer mixes, form mixture, after oversintering, fragmentation, cooling, screening etc. are processed, final finished is transported to the storage of finished product ore storage bin again.
In above-mentioned sintering process, the sintered material system often there will be restarts or the stop and start phenomenon.For system is restarted phenomenon (also can be called along opening phenomenon), because the sintered material system is just to start after mixing the material full scale clearance unloaded on belt, therefore each feed bin delay time discharging default according to self, what on the mixing belt, transmit is also material up to specification, not there will be and lacks the material phenomenon.But for stop and start phenomenon (being the phenomenon that reopens again work after the sintered material system halt), if after system starts, also default discharging delay time according to self of each feed bin, mix the material gathered on belt and just there will be scarce material phenomenon, if still carry out sintering in the situation that lack certain material, can affect the quality of finished product.For example, if there is no fuel in mixture, mixture abundant sintering just, cause occurring a large amount of waste products so; If there is no flux in mixture, can cause the basicity of finished product too low, be still waste product.Produce waste product for fear of sintering in scarce material situation, generally, the mixture that will lack certain material is considered as waste material, it is not carried out to sintering processes, and this just causes the great wasting of resources.
As shown in Figure 2, mix the structural representation of the stockpile gathered on belt while occurring restarting phenomenon for system normal operation or system, No. 1 feed bin is at T
1the time material A that it is inner is unloaded to mixes on belt, through d delay time
1after, No. 2 feed bins are at T
2(T
2=T
1+ d
1) the time material B that it is inner is unloaded to and mixes on belt, now mixes the blanking position that just in time is sent to No. 2 feed bins on belt with the stockpile of material A, the layered laminate stockpile that the two formation comprises material A and B; Then pass through d delay time
2after, the stockpile that comprises material A and B is sent to the blanking position of No. 3 feed bins, and No. 3 feed bins are at T
3(T
3=T
2+ d
2) the time material C that it is inner is unloaded to and mixes on belt, the layered laminate stockpile formed by material A, B and C continues to next feed bin transmission again; According to said process, until be sent to last feed bin of feed bin group, then mix the material gathered on belt and just enter the mixer mixing.
But, after the system stop and start, mix the stockpile transmitted on belt and just there will be scarce material phenomenon.As shown in Figure 3, mix the stockpile gathered on belt during for system halt, mix on the position that belt is corresponding with No. 2 feed bins and gather the stockpile that comprises material A is arranged, gather the stockpile that comprises material A and B is arranged on the mixing belt position corresponding with No. 3 feed bins, by that analogy.After system starts again, No. 1 feed bin blanking immediately, No. 2 feed bin needs through d
1delay time after just blanking, now, when the stockpile under No. 2 feed bins is sent to the position of No. 3 bin blankings, lack material B in stockpile; And No. 3 feed bins need to pass through d
2just blanking delay time, that is to say in No. 3 feed bins are sent to the stockpile of next feed bin and lack material C, by that analogy, this just makes system after stop and start, mixes the material transmitted on belt and the material phenomenon occurs lacking.
Summary of the invention
The embodiment of the present invention provides a kind of bin blanking control method and device of sintered material system, when realizing the system stop and start, mixes the purpose that the material phenomenon does not appear lacking in the material gathered on belt.
For this reason, the invention provides following technical scheme:
