Problems solved by technology

[0002] The problems existing in the existing pulverized coal feeder in our country, because the moisture content of the pulverized coal is different, and the quality of the coal is different, causing many problems. The existing screw feeding method often has uneven and unstable feeding during use. Phenomenon, combustion is prone to vulcanization, deflagration and other phenomena

Embodiment

[0054]Start the motor 1, reducer 2 drives the screw shaft 5 to rotate, and the screw blade 6 connected to the screw shaft 5 through the support frame 7 pushes the coal powder falling from the feed hopper 16 to the disc 19, and under the action of the material rack 13, The pulverized coal enters the hopper 11, and the hopper 11 lifts the pulverized coal from the bottom 5 of the turntable 12 under the rotation of the turntable 12, and starts to unload the material above the disc 19. After the pulverized coal is poured out from the hopper 11, it passes through the disc The discharge hole 31 on the disc 19 falls into the disc 19, slides down through the diverter plate 30 along the inner discharge slant plate 17 of the disc 19, and enters the outlet through the discharge hole 29 on the outer blocking plate 18 of the disc. The material box body 10 enters the boiler through the discharge port 9 below the discharge box body 10 .

Abstract

A feeder for a new pulverized coal boiler includes a motor, a reducer, a screw feeding mechanism, a material lifting mechanism, a material discharging mechanism and a machine base. The invention realizes automatic mechanical feeding, is not affected by moisture in pulverized coal, has small running resistance, high stability, and is safe and reliable. The spiral feed compression air hole in the present invention solves the fluidization effect of coal powder with water content greater than 8%. The air intake of the breathing cap in the present invention can make the feeder operate under negative pressure, so that the pulverized coal can be discharged more smoothly. The rotary lifting and feeding adopted by the invention solves the problem of uneven and unstable feeding and unloading in the prior art, and also solves the problems of vulcanization and deflagration in boiler combustion.

Description

technical field [0001] The invention relates to the field of boiler combustion, in particular to a feeder for a new pulverized coal boiler. Background technique [0002] The problems existing in the existing pulverized coal feeder in our country, because the moisture content of the pulverized coal is different, and the quality of the coal is different, causing many problems. The existing screw feeding method often has uneven and unstable feeding during use. Phenomenon, combustion is prone to vulcanization, deflagration and other phenomena. Contents of the invention [0003] In summary, the object of the present invention is to provide a feeder for a new pulverized coal boiler. [0004] The purpose of the present invention is achieved by the following technologies: [0005] A feeder for a new type of pulverized coal boiler, including a first motor, a first reducer, a screw feed support, a first bearing seat, a screw shaft, a screw blade, a support frame, a screw feed comp...
