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 the feed bin blanking control method and the device of a kind of sintered material system.
Background technology
As shown in Figure 1; Be the system architecture scheme drawing of sintered material system, wherein, the feed bin group can comprise a plurality of feed bins 10; A kind of materials of splendid attire in each feed bin 10 (material can comprise mixing ore deposit, limestone, return mine and mix expect etc.); Below feed bin, be provided with at least one blanking disk 11, the exit of each blanking disk also is provided with a blanking belt conveyer scale 12 respectively, and blanking disk 11 and blanking belt conveyer scale cooresponding with it 12 constitute blanking row.When the sintered material system works; Each feed bin is respectively according to self preset delay time; The material of splendid attire in the feed bin is dumped into the blanking disk by a certain percentage; And then material is dumped into corresponding blanking belt conveyer scale through the outlet of blanking disk, finally material is sent to and mixes belt 20 by the blanking belt conveyer scale.
Mix belt and be used to gather the discharged material of each feed bin; And according to the direction operation that illustrates f; Mixed material is sent to the mixer (not shown), after mixing through twice mixer, forms mixture; After oversintering, fragmentation, cooling, screening etc. are handled, final finished is transported to the storage of finished product ore storage bin again.
In above-mentioned sintering process, the sintered material system occurs restarting or the stop and start phenomenon through regular meeting.For phenomenon (also can be called along opening phenomenon) is restarted in system; Because just startup after the discharged material full scale clearance on the belt will mix in the sintered material system; Therefore each feed bin is according to self preset delay time discharging; What transmit on the mixing belt also is material up to specification, the material phenomenon can not occur lacking.But for stop and start phenomenon (being the phenomenon of the work of opening again again after the sintered material system halt); If after system start-up; Each feed bin is also according to self preset delay time discharging; Then mix the material that gathers on the belt and the material phenomenon will occur lacking,, then can influence the quality of finished product if still carry out sintering under the situation of certain material lacking.For example, if there is not fuel in the mixture, mixture abundant sintering just causes occurring a large amount of waste products so; If there is not flux in the mixture, then can cause the basicity of finished product low excessively, still be waste product.Produce waste product for fear of sintering under scarce material situation, generally speaking, the mixture that will lack certain material is regarded as waste material, it is not carried out sintering processes, and this just causes the great wasting of resources.
As shown in Figure 2, mix the structural representation of the stockpile that gathers on the belt when occurring restarting phenomenon for system's normal operation or system, No. 1 feed bin is at T
1Time is unloaded to its in-to-in material A mixes on the belt, through d delay time
1After, No. 2 feed bins are at T
2(T
2=T
1+ d
1) time is unloaded to its in-to-in material B and mixes on the belt, mix the blanking position that the stockpile that has material A on the belt just in time is sent to No. 2 feed bins this moment, and the two formation comprises the layered laminate stockpile of material A and B; Pass through d delay time then
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) time is unloaded to its in-to-in material C and mixes on the belt, the layered laminate stockpile that is formed by material A, B and C continues to next feed bin transmission again; According to said process,, mix the material that gathers on the belt then and just get into the mixer mixing until last feed bin that is sent to the feed bin group.
But, after system's stop and start, mix the stockpile that transmits on the belt and the material phenomenon will occur lacking.As shown in Figure 3; Mix the stockpile that has gathered on the belt during for system halt; Mixing to gather on belt and No. 2 cooresponding positions of feed bin has the stockpile that comprises material A, and gathering on mixing belt and No. 3 cooresponding positions of feed bin has the stockpile that comprises material A and B, by that analogy.After system starts once more, No. 1 feed bin blanking immediately, No. 2 feed bin then need pass through d
1Delay time after just blanking, at this moment, when the stockpile under No. 2 feed bins is sent to the position of No. 3 feed bin blankings, lack material B in the stockpile; And No. 3 feed bins need 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 to lack material C that by that analogy, this just makes system after stop and start, mixes the material that transmits on the belt and the material phenomenon occurs lacking.
Summary of the invention
The embodiment of the invention provides the feed bin blanking control method and the device of a kind of sintered material system, when realizing system's stop and start, mixes the purpose that the material phenomenon does not appear lacking in the material that gathers on the belt.
For this reason, the present invention provides following technical scheme:
The feed bin blanking control method of a kind of sintered material system, said method comprises:
Obtain the mode of operation of sintered material system:
If said mode of operation is a rebooting status, after then the feed bin in said sintered material system starts, control said feed bin according to preset blanking delay time;
If said mode of operation is the stop and start state, after then the feed bin in said sintered material system starts, control the blanking immediately of said feed bin.
The feed bin blanking control setup of a kind of sintered material system, said device comprises:
