The invention discloses a weighing coal feeder which comprises a shell assembly, a coal conveying mechanism, a weighing mechanism and an electrical control system. The shell assembly comprises an outer shell, a feeding port is formed in the upper end of the outer shell, a thrust electric rotating gate is arranged at the upper end of the feeding port, a shaping hopper is arranged between the thrust electric rotating gate and the feeding port, and a rectifying assembly is arranged in the shaping hopper; the rectifying assembly comprises a material guide table fixed in the shaping hopper, and material guide slopes are arranged on one pair of side faces of the material guide table respectively. A material guide hole is formed in the upper portion of the material guide table and penetrates through the top of the material guide table. A material guide hopper is arranged on one side above the material guide hole, the material guide hopper is embedded in one side of the shaping hopper, and the electric rotating gate is used for conveying coal added into the feeding port into the material guide hopper. According to the invention, the situation that the whole coal feeder is easy to slip, stick, deviate and the like can be ensured and improved, and the problem of boiler coal feeding interruption can be solved.
Description
technical field [0001] The invention relates to the field of metering and feeding equipment, in particular to a weighing coal feeder. Background technique [0002] Weighing coal feeder is the main coal feeding equipment used for circulating fluidized bed boilers and pulverized coal furnaces in coal-fired thermal power plants. At present, the weighing coal feeder on the market mainly realizes the weighing of coal lumps by arranging the weighing sensor under the weighing roller in the shell of the weighing coal feeder. However, with this weighing method, the belt is deviated due to the coal coiling into the driven drum, which makes the coal feeder easy to slip and deviated, causing the problem of interruption of coal feeding to the boiler; at the same time, the existing weighing machine Lack of air-drying of the coal, the coal is prone to sticking during the conveying and weighing process. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide...
