Description
Technical field
The utility model relates to a kind of cement mill clinker production line security logic control device, especially cement mill clinker production line cement grinding and conveying workshop section is improved the control device of safe operation.
Background technology
Though the cement clinker production line of current cement mill all has been equipped with computer control system; But design and develop personnel and field operator and be distinct, two companies fully independently; Be that the The Automation Design Developmental Engineer is stranger to cement mill limestone crushing workshop section production technology, on-the-spot cement manufacture plant, and field maintemance and operation slip-stick artist do not understand develop computer software, so computer control system has only intensive data to gather Presentation Function; Basically there is not rigorous, careful logical security controlling schemes; On-the-spot all equipment all is isolated operation basically, main experience and the profile who depends on middle control operator of the quality of operation, and for example to start, stop all be that middle control operator, Onsite Maintenance Engineer are worked in coordination to field apparatus basically; Through an operation of unit; Operation is also held enforcement with operator's personal experience basically, and on-the-spot tiny hidden trouble of equipment also is difficult to find, accumulates over a long period; Big equipment breakdown has to shut down, and stop time is longer.Operating personnel and maintainer's labour intensity are bigger in this case, and equipment breakdown is more, and production is longer stop time, and the year running rate of equipment is lower, and the operation power consumption is higher, and output is lower, benefit is lower.
Summary of the invention
In order to reduce operating personnel and maintainer's labour intensity, reduction equipment failure, raising equipment year running rate, reduce the operation power consumption, improve output, to improve the performance of enterprises, the utility model provides a kind of cement mill clinker production line limestone crushing and carries workshop section's security logic control device.Utilize computer control system with this workshop section's all devices logic control of cement mill clinker production line, safety interlocking, automatic start-stop, guaranteed the production of employee's device security.
The utility model solves the technical scheme that its technical matters adopted: a kind of cement grinding and conveying workshop section security logic control device is characterized in that: it comprises computer control system, raw material batcher, 1# rubber conveyer, 2# rubber conveyer, goes into to grind hoister, 3# rubber conveyer, V-arrangement powder concentrator, electric brake plate valve, current stabilization storehouse, roll squeezer, dust-precipitator blower fan, rotoclone collector, bowl mill, 4# rubber conveyer, warehouse-in hoister, air conveyer flume, skewed slot blower fan, cement silo; Each equipment is pressed the cement grinding process order and is linked to each other; At the bottom of cement clinker storehouse, lime stone storehouse, gypsum storehouse, each storehouse, copper mine slag storehouse through the raw material batcher with raw material by under certain proportioning to same belt; Successively through 1# rubber conveyer, 2# rubber conveyer, go into to grind hoister, 3# rubber conveyer and get into the V-arrangement powder concentrator, select powder through powder concentrator after, meal is admitted to the current stabilization storehouse; Arrive the preliminary grinding of roll squeezer down; Through going into to grind hoister, the screening of 3# rubber conveyer entering V-arrangement powder concentrator, final qualified fine powder gets into rotoclone collector to the fine powder that grinds, and gets into bowl mill through rotoclone collector once more; Carry out combined grinding, the cement fine powder after going out to grind finally is admitted to cement silo through 4# rubber conveyer, warehouse-in hoister, air conveyer flume successively.Computer control system realizes supervision, control and the operation to workshop section's all devices.
During cement grinding system start-up; End-equipment from grinding system; Be that the skewed slot blower fan at first begins to start; By putting hoister, 4# rubber conveyer, bowl mill, dust-precipitator blower fan, rotoclone collector, roll squeezer, electric brake plate valve, 3# rubber conveyer in storage, going into to grind hoister, 2# rubber conveyer, 1# rubber conveyer, raw material batcher successively step by step forward, finish then until starting all.Each step is all added their confirmation by feedback signal in the start-up course, just carries out next step after only being identified actual startup; If a certain step starts failure, then grinding system stops to start.
When cement grinding system start-up and operation, the mutual safety interlocking of each equipment room, if arbitrary device fails, then armamentarium is jumped and is stopped, and sends alerting signal, informs the operator.
When the cement grinding system stops; Just opposite with boot sequence; Promptly from system foremost the raw material batcher begin to stop; By 1# rubber conveyer, 2# rubber conveyer, go into to grind hoister, 3# rubber conveyer, electric brake plate valve, roll squeezer, rotoclone collector, dust-precipitator blower fan, bowl mill, 4# rubber conveyer, warehouse-in hoister, the skewed slot blower fan by platform backward, all stops until armamentarium successively.
The beneficial effect of the utility model is, utilizes computer control system with cement mill clinker production line apparatus logic control, safety interlocking, automatic start-stop, guaranteed the safety of employee and equipment; Reduce operating personnel and maintainer's labour intensity; Reduce equipment failure, raising equipment year running rate reduces the operation power consumption; Improve output, improve the performance of enterprises.
