Problems solved by technology

However, due to the high viscosity of pulverized coal, a bridge will be built in the hopper during the powder feeding process, which will hinder the continuous feeding of pulverized coal. To solve this problem, a vibrator is generally installed to periodically However, this design has its own defects. On the one hand, if the vibration amplitude is small, the phenomenon of pulverized coal bridging in the hopper cannot be solved; on the other hand, if the vibration amplitude is too large, it will drive the bearing, coupling Shaft, motor and other equipment vibrate together, affecting the normal operation of the powder feeding device and the powder feeding accuracy

Abstract

The invention belongs to the technical field of powder feeding. According to a powder feeding device, the technical problem that as for an existing powder feeding device, the coal powder bridging phenomenon is likely to occur, and thus feeding precision is low is solved. The powder feeding device comprises a feeding motor, a spiral shaft, a powder feeding pipe, a stirring motor, a hopper and a stirrer. The spiral shaft is arranged in the powder feeding pipe and connected with the output end of the powder feeding motor. An opening is formed in the upper portion of the powder feeding pipe. The lower end of the hopper is arranged over the opening. The stirrer is mounted in the hopper and connected with an output shaft of the stirring motor. The powder feeding device has the beneficial effectsthat the coal powder bridging phenomenon is avoided, normal operation can be achieved, and the powder feeding precision is high.

Description

technical field [0001] The invention belongs to the technical field of powder feeding, and in particular relates to a powder feeding device. Background technique [0002] In order to realize the continuous and uniform transportation of pulverized coal, a powder feeding device is generally used. Among them, the screw powder feeding device is widely used due to its simple structure, practicality, and convenient operation. However, due to the high viscosity of pulverized coal, a bridge will be built in the hopper during the powder feeding process, which will hinder the continuous feeding of pulverized coal. To solve this problem, a vibrator is generally installed to periodically However, this design has its own defects. On the one hand, if the vibration amplitude is small, the phenomenon of pulverized coal bridging in the hopper cannot be solved; on the other hand, if the vibration amplitude is too large, it will drive the bearing, coupling Shaft, motor and other equipment vi...
