Activation coal feeder

Abstract

The invention discloses an activation coal feeder in the technical field of coal feeders. The feeder comprises a rack and a supporting frame, the rack is provided with a vibration box, a discharging opening is formed in the bottom of the vibration box, the vibration box is provided with a shock excitation mechanism for driving the vibration box to vibrate, the shock excitation mechanism comprises a motor frame and a vibration motor on one side of the vibration box, multiple shock excitation springs are arranged between the motor frame and the vibration box, a coal bin extending into the vibration box and mounted on the supporting frame is arranged above the vibration box, a shearing assembly located below an outlet of the coal bin is arranged in the vibration box, the coal bin is provided with a mounting part facilitating mounting of the shearing assembly, the shearing assembly comprises multiple cutter sets mounted between the mounting part and the vibration box, multiple telescopic parts are arranged between two adjacent cutter sets, the telescopic direction of the telescopic parts is consistent with the telescopic direction of the shock excitation springs, each cutter set comprises a cutter plate and multiple blades arranged on the side face of the cutter plate, and a first interval is reserved between the blades of two adjacent cutter plates. The feeder has the advantage of preventing coal from being blocked and improving activation.

Description

technical field [0001] The invention relates to the technical field of coal feeders, in particular to an activated coal feeder. Background technique [0002] A utility model is disclosed in the prior art, the authorized announcement number is CN205328119U, and the authorized announcement date is 20160622. The feed inlet and the bottom of the conveying box are elastically supported, the side of the conveying box is connected with an electric vibrator, the upper part of the conveying box has a diverter plate, and the lower part of the diverter plate has a curved groove, and the groove bottom of the curved groove is The discharge port has two to six horizontal through holes between the opposite sides of the discharge port of the material conveying box, and straight rods are inserted in the through holes. The activated coal feeder in the prior art organically combines the feeding function and the function of activating the material, effectively eliminating the problem of expans...

AI Technical Summary

Problems solved by technology

The activated coal feeder in the prior art organically combines the feeding function and the function of activating the material, effectively eliminating the problem of expansion and blockage, but there are still the following problems: due to the difference in coal quality and the difference in water content , the coal in the coal bunker will stick into blocks. When the coal feeder feeds the material, although the material will automatically fall while being loosened by vibration, due to the agglomeration of the material, the material cannot be loosened in time and effectively, which will cause Feeding delay phenomenon

Although the existing technology improves the activation to a certain extent through the activation rod, for the coal with high water content, the material is very agglomerated, it is difficult to fully activate it with the activation rod, and it is still easy to produce a large amount of agglomerated coal. Moreover, the degree of disturbance of the activation rod is slow, the disturbance range is small, and the effect of rapid activation cannot be achieved.
