Problems solved by technology

Once the above problems occur and the driver fails to find out in time, coke overflow coke tank accidents will occur, resulting in major equipment losses and even personal injuries
This method is easy to do at night, but it is more difficult to judge during the day

Embodiment Construction

[0014] see figure 1 , a coke-free detection method provided by the invention, which comprises,

[0015] a) A number of material level gauges are evenly installed along the circumferential direction on the top of the CDQ furnace. After the CDQ crane loads the red coke into the CDQ furnace, the material level value of the coke in the CDQ furnace can be obtained through the detection of the material level gauge. , every time it is loaded, the height of coke in the CDQ furnace will rise by 500mm. If the height of the material level in the CDQ furnace rises less than 300mm after red coke is loaded, an alarm signal will be issued to remind the operator to check whether there is residual red coke in the coke tank. coke;

[0016] b) When the crane rises to the top of the hanging tower, it will stop for a few seconds, and the crane will use the weighing system to weigh the total weight and save it. Then, when the crane has filled the red coke cans and returned to the top of the hangin...

Abstract

A method for detecting no coke in a coke drum, comprising: a) installing several material level gauges evenly along the circumferential direction on the top of the CDQ furnace; The value of the coke material level in the CDQ furnace is obtained through the detection of the meter. Every time it is loaded, the height of the coke in the CDQ furnace will rise by 450‑500mm. Alarm signal; b) When the crane rises to the top of the pendant tower, stop for a few seconds, use the crane weighing system to weigh the total weight and save it, and then when the crane returns to the top of the pendant tower after the red coke cans are filled, again Stop for a few seconds to weigh, and subtract the weighing data before the crane loads the red coke with the weighing data after the crane loads the red coke to get the amount of red coke loaded. If the amount of red coke loaded by the crane is greater than The set value means that everything is loaded, if it is less than the set value, it means that there is residual red coke, and an alarm signal is sent for confirmation by the operator.

Description

technical field [0001] The invention relates to coke oven technology, in particular to a method for detecting no coke in a coke tank. Background technique [0002] The coke pushing operation of the coke oven is completed by four major locomotives: coke pushing car, coke guiding car, coal loading car and coke transporting car. The coke pusher pushes the coke in the carbonization chamber into the empty coke tank, and the coke truck transports the full coke tank to the CDQ system. After the coke is loaded into the CDQ oven, the empty coke tank returns to the coke truck to continue the next furnace No. coke receiving operation. The design volume of the coke tank can only accommodate one furnace of coke. After each coke pushing operation, it must be confirmed that the coke in the coke tank has been loaded into the CDQ oven before re-connecting the coke. Otherwise, the coke at about 1050°C will overflow the coke tank. Burnt coke truck and other equipment. During the coke pushin...
