Fig. 1 is composition and the control flow schematic diagram of embodiment bulk material storing and transporting system.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Intelligent environment protection bulk material storing and transporting system as shown in Figure 1, be included in discharge, transhipment portion, processing handling part, stockyard portion, the discharging point in charging portion or airborne dust point and the detecting device a, detecting device b, detecting device c, detecting device d, the detecting device e that detect air-borne dust concentration are set, and dust collector A, dust collector B, dust collector C, dust collector D, dust collector E etc.; The PLC control system that each dust collector runs; Each air-borne dust concentration detection apparatus is used for gathering air-borne dust concentration data; The data gathered are by data line or wireless signal feedback to PLC control system, and data transfer mode can adopt the type of transmission such as RS232/485 communication protocol, 200 ~ 1000 Hz or 4 ~ 20mA.Discharge comprises discharging room and delivery device, and discharging room is full-enclosed structure; Transhipment portion comprises input and output material transfer point, vestibule and inner relevant device, and transfer point is full-enclosed structure; Processing handling part comprises at least one item among crushing and screening, abrasive dust, mixing or dry run and relevant device; Workshop is full-enclosed structure; Stockyard portion comprises material and stacks place and relevant heap reclaimer device thereof; Charging portion is full-enclosed structure; In the present invention, air dust concentration detecting device can select LD-5 laser on-line detector or AQM-8000 on-line detecting system.
In operational process, utilization is arranged in each discharging point of bulk material storing and transporting system, the air-borne dust concentration detection apparatus of airborne dust point gathers air-borne dust concentration data; The data gathered by data line or wireless signal feedback to PLC control system; The data of collection and the dust concentration controlling valu pre-set compare by PLC control system; When the data of certain some air-borne dust concentration detection apparatus collection reach dust concentration upper limit controlling valu, control system controls the increasing of this dust collector and exerts oneself; When the data of certain some air-borne dust concentration detection apparatus collection reach dust concentration lower limit controlling valu, control system controls this dust collector and turns down and exert oneself.The data of air-borne dust concentration detection apparatus collection can preserve, show or print.
During in order to avoid comparatively long distance delivery, the zero load waste of follow-up equipment and when avoiding simultaneously starting, the starting current load of whole system is excessive.Bulk material storing and transporting system is when starting, PLC controls each equipment and starts according to the sequencing of bulk material by each equipment, corresponding each equipment discharging point, the dust collector of airborne dust point and air-borne dust concentration detection apparatus are also controlled to start sequentially by PLC, dust collector is by first starting dust collector A, start dust collector B successively again, dust collector C, dust collector D, the sequence starting of dust collector E, air-borne dust concentration detection apparatus is also enabled sequentially, by first starting air-borne dust concentration detection apparatus a, start air-borne dust concentration detection apparatus b successively again, air-borne dust concentration detection apparatus c, air-borne dust concentration detection apparatus d, the sequence starting of air-borne dust concentration detection apparatus e.PLC controls the interval time of dust collector and the startup of air-borne dust concentration detection apparatus from the current dedusting position time be transported to needed for next dedusting position by bulk material.
When bulk material storing and transporting system reloads or initial start runs, the startup hysteresis of each air-borne dust concentration detection apparatus, and need just startup after bulk material arrives accumulating corresponding to this dust collector or Fabricating machinery in the dust collector of corresponding detection.Can avoid because of air-borne dust concentration detection apparatus pre-cooling, after the low dust concentration value detected feeds back to PLC, PLC sends out-of-work instruction to this dust collector; And when bulk material arrives this point and produces dust, after the normal dust concentration value that air-borne dust concentration detection apparatus detects feeds back to PLC, PLC sends enabled instruction to dust collector, thus causes the repeated priming of this dust collector.As dust collector A start a period of time after detecting device a restart, dust collector A need start before bulk material arrives at, that is dust collector A starts, and now bulk material does not also arrive at discharge (namely this position does not also produce dust), if now air-borne dust concentration detection apparatus a also starts, the low dust concentration value signal a detected can be fed back to PLC, the signal a that PLC feeds back according to air-borne dust concentration detection apparatus a, can send out-of-work signal to dust collector A; And bulk material arrives this point following closely and produces dust, air-borne dust concentration detection apparatus will detect that the number signal data feedback of normal dust sends enabled instruction to PLC, PLC to dust collector A again, thus causes dust collector A repeated priming.Delayed startup can effectively avoid dust collector to repeat start and stop, reduces the harmful effect that frequent start-stop causes dusting equipment.
In prior art, the size that the initial start due to dust collector is exerted oneself not is carry out according to the data of present air dust concentration detecting device feedback, but carry out according to the data be recorded in PLC before last time shutdown; When the material carried is changed, dust collector exert oneself often lower than or exceed normal dedusting and to exert oneself demand, need wait until that the air-borne dust concentration detection apparatus of this point starts rear and detects that the dust concentration of this point feeds back to PLC, assigned the instruction of changing and exerting oneself again to this dust collector by PLC, there is a Delay Process, the waste that this Delay Process will cause the discharge beyond standards of dust or dust collector to be exerted oneself, adds dust collector simultaneously and exerts oneself and adjust frequency.Technical scheme provided by the invention, bulk material storing and transporting system is when reloading or initial start runs, PLC is with a upper air-borne dust concentration detection apparatus except dirt pits (bulk cargo arrives at) of dust collector to be launched, based on the dust concentration maxim of secondary detection, assign initial start to dust collector (bulk cargo does not also arrive at) to be launched to exert oneself large small instruction, the dedusting of dust collector to be launched is exerted oneself adapt to well dust collector to exert oneself the real demand of size, the pollution to environment can be reduced, economize energy and material amounts.Such as: in prior art, due to dust collector B be air-borne dust concentration detection apparatus b before open, so the size that its initial start is exerted oneself not is carry out according to the data of air-borne dust concentration detection apparatus b current feedback, but carry out according to the data being recorded in PLC control center before last time shutdown, if this dedusting of recording in PLC last time is exerted oneself as Q just can meet dust removal requirement, and this changes bulk cargo 2 or bulk cargo 3 owing to carrying bulk material type into from bulk cargo 1, its dust collector actual needs (Q ± X) of exerting oneself just can meet dust removal requirement, when dust arrives at this, exert oneself as Q due to dust collector B, be actually and cannot meet dust removal requirement or exceed dust removal requirement, need wait until that air-borne dust concentration detection apparatus b starts and after detecting that the dust concentration of this point feeds back to PLC, assigned the instruction of changing and exerting oneself again to dust collector B by PLC, a Delay Process is just had in the middle of this, this Delay Process will cause part dust not process in time, affect air ambient, or cause the waste that dedusting is exerted oneself, add dust collector to exert oneself and adjust frequency simultaneously.Technical scheme provided by the invention, for avoiding the generation of this situation, PLC does not also arrive to dust collector B(bulk cargo based on the maximum dust concentration data-signal time to detect by the air-borne dust concentration detection apparatus a of a upper position (bulk cargo arrives at)) to assign initial start and to exert oneself the instruction of size, the initial start of dust collector B size of exerting oneself adapts to the real demand of dust removal operation well; After air-borne dust concentration detection apparatus b starts, PLC just assigns to dust collector B instruction of exerting oneself according to the data detection signal of air-borne dust concentration detection apparatus b, and PLC ceases to be in force automatically by the initial start that a upper position the provides high low signal a that exerts oneself.
Due to the particularity of Bulk material process; there is the situation (supplied materials is discontinuous) of intermittent delivery; when occurring being interrupted conveying condition; except dirt pits is not when having material; dust concentration is lower; after now the testing result of air-borne dust concentration detection apparatus feeds back to PLC, PLC will be caused to assign halt instruction to dust collector, bring exceeding standard of the repeatedly starting and stopping of dust collector and quantity discharged.Technical scheme provided by the invention; bulk material storing and transporting system is in operational process; current dust collector adjacent two is except any one the dust concentration value detected in the air-borne dust concentration detection apparatus of dust collector is more than this dust collector air-borne dust concentration shutdown concentration value, and PLC can not assign halt instruction to current dust collector.Such as; when detecting device d detect air-borne dust concentration value reach make PLC send make dust collector D halt instruction; but when the dust concentration value that in detecting device c or detecting device e, any one detects is shut down more than concentration value in dust collector D air-borne dust concentration, PLC can not assign halt instruction to dust collector D.But when occurring that in operational process material is interrupted the situation of conveying; when the data of certain some air-borne dust concentration detection apparatus collection are lower than shutdown concentration value; and the data that the air-borne dust concentration detection apparatus of adjacent two dust collectors gathers are all lower than when shutting down concentration value, control system controls the operation stopping this dust collector.
The construction of bulk material storing and transporting system is full-enclosed structure, and prevention outdoor wind-force causes air to flow, and affects the Detection results of detecting device to dust concentration.
Obviously, the invention is not restricted to above preferred implementation, in the spirit that also can limit in the claims in the present invention and specification sheets, carry out conversion and the improvement of various ways, can same technical matters be solved, and obtain the technique effect of expection, therefore not repeat.Those of ordinary skill in the art can from content disclosed by the invention directly or all schemes associated, as long as within the spirit limited in claim, also belong to protection scope of the present invention.
