Problems solved by technology

[0002] Although the cement clinker production line of the current cement plant is equipped with a computer control system, the design and development personnel and the on-site operation personnel are completely separate and independent companies, that is, the automation design and development engineers are responsible for the production process of the limestone crushing section of the cement plant, The on-site cement production equipment is relatively unfamiliar, and the on-site maintenance and operation engineers do not understand computer software development, so the computer control system only has the function of centralized data collection and display, and basically does not have a rigorous and careful logical security control plan. It operates in isolation, and the quality of operation mainly depends on t

Embodiment Construction

[0015] exist figure 1 Among them, a limestone crushing and transportation safety logic control device is characterized in that it includes a computer control system, apron feeder (1), crusher (2), 1# belt conveyor (3) and 2# belt conveyor machine (4), the apron feeder (1) is connected with the inlet of the crusher (2), and the outlet of the crusher (2) passes through 1# belt conveyor (3), 2# belt conveyor (4) and the limestone pre-homogeneous Chemical storage yard (5) is connected. The limestone mined from the mine is piled up in the open-air storage yard of the cement factory, and the limestone is poured into the receiving hopper by a forklift, and fed into the limestone crusher (2) through a heavy-duty apron feeder (1), and the crushed limestone It is sent to the limestone pre-homogenization yard (5) by 1# belt conveyor (3) and 2# belt conveyor (4).

[0016] When the limestone crushing system starts, the terminal equipment of the crushing system, that is, the 2# belt conveyor
