Abstract
Description
technical field
[0001] The invention relates to the technical field of metallurgical coking equipment, more specifically, a coke oven coal tower coal nozzle control system and method. Background technique
[0002] The coal loading car receiving coal is an important step in the operation of the coal loading car. In the traditional working mode, the coal loading vehicle is receiving coal at the coal tower position of the coal preparation system. When the coal loading vehicle reaches the designated coal receiving position, the coal nozzle of the corresponding position is opened, closed or shakes the coal, and the coke oven coal There are three rows of coal nozzles in the tower, and each row has four coal nozzles. The coal loading car only uses one row of coal nozzles to receive coal at a time, fills up four coal charging hoppers, and transports the coal to the planned furnace number for coal feeding.
[0003] The above scheme has defects: (1) The coal loading vehicle can only ...
Examples
Embodiment 1
[0036] Such as figure 1 As shown, a coke oven coal tower coal nozzle control system includes a coal nozzle control open circuit 1 connected between the live line and the neutral line, a coal nozzle control closed circuit 2, a coal nozzle control alignment interlock circuit 3, and a coal nozzle control loop 3. Mouth closed and interlocked coal loading running unit 4, control coal nozzle is not closed tightly alarm unit 5;
[0037] In practice, the coal nozzle control open circuit 1 is provided with two branches, wherein the first branch is connected with the live wire and the neutral wire; the second branch is connected with the live wire and the coal nozzle control closed circuit.
[0038] The first branch is sequentially connected with selector switch SSA1, stop button SS, open button SF, coal nozzle open limit SQF, KA1 normally open auxiliary point KA1-1, coal nozzle close contactor KAC normally closed auxiliary point KAC- 1. Coal nozzle opening contactor KRC;
[0039] One...
Embodiment 2
[0051] Such as figure 2 As shown, a coke oven coal tower coal nozzle control method includes:
[0052] S1. The coal loading car sends out an open command through the electromagnet, so that the open magnetic control switch KTA controls the coil of the coal nozzle open contactor KRC to energize;
[0053] S2. Open to the position and press to the coal nozzle open limit SQF control contactor KRC coil power off, start receiving coal;
[0054] S3. After the coal hopper is filled with coal, the coal loading truck sends a closing command through the electromagnet;
[0055] S4. Close the magnetic control switch KTR to control the coil of the coal nozzle to close the contactor KAC to get electricity. After the coal nozzle is closed tightly, press it to the limit position of the coal nozzle. SQR controls the closing of the intermediate relay KA and the coal nozzle to close the contactor. Coal is done.
[0056] During specific implementation, the described coal receiving process also ...
