The invention relates to a bulk material trolley control system of an annular cooler and a control method thereof, comprising a proximity switch magnet, a bulk material trolley on the traveling track of the bulk material trolley, and a proximity switch magnet located under the bulk material ash hopper and at the position of the discharge point. Limit switch contacts at both ends of the traveling track of the trolley, proximity switches and limit switches on both sides of the bulk material trolley, electronic belt scales at the outlet of the annular cooler, motor actuators of the bulk material trolley and computer analog control systems, proximity switches and limit switches The switch signal is connected to the computer analog control system, and the flow signal of the electronic belt scale is communicated with the signal of the motor actuator of the bulk material trolley through the computer analog control system. Compared with the existing technology, the beneficial effect of the present invention is: according to the change of the material flow rate at the outlet of the annular cooler, a feasible task list for the bulk material trolley is formulated, and the system can adjust the task list in real time according to the change of the material flow rate at the outlet , improve the unloading efficiency of the bulk trolley, and improve the automation level of the whole plant.
Description
technical field [0001] The invention relates to the technical field of industrial computer real-time control, in particular to a control system and a control method for a bulk material trolley of an annular cooler. Background technique [0002] The annular cooler is an important component of the cooling system in the production process of sinter and pellets. The rotary body of the ring cooler is driven to rotate by the main motor, reducer, open gear and sprocket. With the rotation of the rotary body, the hot pellets and hot sintered ore produced in the previous process will continuously fall to the trolley with grate holes in the rotary body through the feeding hopper. After the trolley rotates slowly, the minerals are gradually cooled by the cooling air from the lower part of the trolley, and finally discharged to the discharge port to enter the next production link. During the cooling process, mineral bulk materials and dust fall from the grate hole of the trolley to the...
