A circular rotating coke tank balance detection device and method

Abstract

The invention relates to a balance detection device and method for round rotary coke pots. The device is composed of a first infrared detecting device, a second infrared detecting device, a first infrared reflection plate, a second infrared reflection plate, a PLC and a mechanical pendulum rod limiting device; two reflected light beams received by the two infrared detecting devices form two analogquantity data respectively; whether the difference value signal of the two analog quantity data is within a permissible range is judged through the PLC; the PLC generates coke pot balance signals ifthe difference value signal of the two analog quantity data is within the permissible range; when a round rotary coke pot is normally put down in place, limiting pendulum rod turning-on signals are generated, and the PLC generates coke pot in-place signals after receiving the limiting pendulum rod turning-on signals; and if both the coke pot balance signals and the coke pot in-place signals are generated in the PLC, it is indicated that the position of the round rotary coke pot is normal, otherwise, the coke pot stops operating. According to the balance detection device and method for the round rotary coke pots of the invention, by means of the infrared ray detection of sensors and the detection of the balance position of the round rotary coke pot, the normal rotation of the position of the coke pot can be ensured, and the coke pot can be prevented from slipping out to damage equipment.

Description

technical field [0001] The invention relates to a focus pushing operation technology, in particular to a circular rotating coke tank balance detection device and method. Background technique [0002] The coke pushing operation of the coke oven is completed by the cooperation of four locomotives: coke pushing car, coke guiding car, coal loading car and tram. The coke pusher pushes the coke in the carbonization chamber to the round empty coke tank loaded by the trolley hauler through the coke guide car. Rotate through the driving device, and after receiving the red coke, the circular coke tank stops at the specified position through the limit detection; the full coke tank is transported by the tram to the CDQ traction place, and the red coke tank is loaded by the CDQ traction The traverse trolley is introduced into the fixed position of the CDQ crane tower, and then the red coke tank is lifted to the upper limit position of the crane by the CDQ crane, and the crane is moved l...

AI Technical Summary

Problems solved by technology

[0003] When the crane is lowering the empty coke pot, the position of the coke pot must coincide with the positioning pin on the rotating disk on the traverse trolley, but sometimes when the crane lifts the red coke pot, the rotation on the traverse trolley The disc will rotate, causing the position to shift. Therefore, when the empty coke tank is put down in place, the bottom of the coke tank will press on the positioning pin of the rotating disc, causing the coke tank to tilt; or coke powder will accumulate at the gate of the coke tank, causing The gate of the coke tank is not properly closed, resulting in inclination

At present, there is no detection device in the crane system and the rotating circular coke tank that rely on CDQ traction to enter and exit the coke tank. When rotating again before coking, the circular coke tank weighing 50 tons will be tilted. Misalignment, slipping out, resulting in damage to equipment such as traversing trolleys, seriously affecting production safety
