An automatic feeding system for the top hopper of the tank furnace

Abstract

The invention belongs to the field of carbon production technologies, and particularly relates to an automatic charging system for tank type furnace roof hoppers, wherein the automatic charging system is used in the carbon industry petroleum coke roasting technology. A material level switch is arranged on each furnace roof hopper, and when green coke in the hoppers is lowered to a certain value, and a control system in a control box can receive signals of the material level switches and send control instructions to a quantitative feeder, a conveying belt and a discharging trolley; and under positioning of a limiting switch, the green coke can be continuously and evenly added in all the hoppers on a tank type furnace roof, and automatic tank type furnace roof charging is finished. According to the automatic charging system for the tank type furnace roof hoppers, automatic control system running replaces modern manual charging operation, necessary manual labor is reduced, labor input is reduced, the labor cost is greatly reduced through input of a small amount of equipment, and the work environment of operation workers is improved. The automatic charging system is not influenced by the subjectivity of manual operation, and real-time performance and reliability of charging are greatly improved.

Description

technical field [0001] The invention belongs to the field of carbon production technology, and in particular relates to an automatic charging system for a top hopper of a pot furnace used in the petroleum coke calcination process of the carbon industry. Background technique [0002] At present, the tank furnace calcination method is increasingly used in the petroleum coke calcination process in the carbon industry. In the tank furnace, the petroleum coke (raw coke) is indirectly heated by the high-temperature flue gas in the flue, so that it can effectively remove moisture and volatile matter. The tank discharge in the tank furnace is carried out according to a certain time sequence, so the raw coke feeding in the tank furnace is an important link in the petroleum coke calcination process. At present, the domestic operation of feeding materials into the hopper of the tank furnace top is manually operated on site, and there are many disadvantages: 1. Due to the subjective fa...
