Abstract
The invention discloses a safety logic control device for crushing and conveying of limestone. The device is characterized by comprising a computer control system, a plate-type feeder, a crusher, a first belt conveyor and a second belt conveyor, wherein the plate-type feeder is connected with an inlet of the crusher; an outlet of the crusher is communicated with a pre-homogenization storage yard of the limestone through the first belt conveyor and the second belt conveyor; and the computer control system can monitor, control and operate all pieces of equipment during the workshop section. By adoption of the device, the safety of staff and the safety of the equipment are guaranteed, the labor intensities of an operator and a maintainer are reduced, equipment failure is reduced, the yearly running rate of the equipment is improved, the power consumption of working procedures is reduced, and yield and enterprise benefit are improved.
Description
Technical field
The present invention relates to a kind of cement mill clinker production line security logic control device, especially cement mill clinker production line limestone crushing and conveying workshop section are 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 present invention 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 technical solution adopted for the present invention to solve the technical problems is: a kind of limestone crushing and conveying workshop section security logic control device; It is characterized in that: it comprises computer control system, board-like feeding machine, disintegrating machine, 1# band conveyor and 2# band conveyor; Board-like feeding machine is connected with the disintegrating machine inlet, and the disintegrating machine outlet communicates with the lime stone pre-homogenization yard through 1# band conveyor, 2# band conveyor; Computer control system realizes supervision, control and the operation to workshop section's all devices.
The lime stone that mining is come is deposited in the open storage ground of cement mill; Pour lime stone into hopper by forklift; Through 1 heavy-duty plate feeding machine feeding limestone crushing machine, the lime stone after the fragmentation is delivered to the lime stone pre-homogenization yard by 1# band conveyor, 2# band conveyor.
During limestone crushing system start-up, from the end-equipment of crushing system, promptly the 2# band conveyor at first begins to start, and then by 1# band conveyor, disintegrating machine, board-like feeding machine step by step forward, finishes 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 crushing system stops to start.
When crushing system starts and move, 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 crushing system stops, just opposite with boot sequence, promptly begin to stop from the board-like foremost feeding machine of system, by disintegrating machine, 1# band conveyor, 2# band conveyor backward, all stop until armamentarium by platform.
The invention has the beneficial effects as follows, utilize computer control system, guaranteed the safety of employee and equipment cement mill clinker production line apparatus logic control, safety interlocking, automatic start-stop; 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.

Embodiment
In Fig. 1; A kind of limestone crushing and delivery safety logic control device; It is characterized in that: it comprises computer control system, board-like feeding machine (1), disintegrating machine (2), 1# band conveyor (3) and 2# band conveyor (4); Board-like feeding machine (1) is connected with disintegrating machine (2) inlet, and disintegrating machine (2) outlet communicates with lime stone pre-homogenization yard (5) through 1# band conveyor (3), 2# band conveyor (4).The lime stone that mining is come is deposited in the open storage ground of cement mill; Pour lime stone into hopper by forklift; Through 1 heavy-duty plate feeding machine (1) feeding limestone crushing machine (2), the lime stone after the fragmentation is delivered to lime stone pre-homogenization yard (5) by 1# band conveyor (3), 2# band conveyor (4).
During limestone crushing system start-up, from the end-equipment of crushing system, promptly 2# band conveyor (4) at first begins to start, and then by 1# band conveyor (3), disintegrating machine (2), board-like feeding machine (1) step by step forward, finishes 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 crushing system stops to start.
When crushing system starts and move, 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 crushing system stops, just opposite with boot sequence, promptly begin to stop from the board-like foremost feeding machine of system (1), by disintegrating machine (2), 1# band conveyor (3), 2# band conveyor (4) backward, all stop until armamentarium by platform.It is enforceable stopping logic, and the affirmation in each step needn't be set.
