Coal feeder with anti-blocking function

Abstract

The invention discloses a coal feeder with an anti-blocking function, and relates to the field of coal feeders. The coal feeder comprises a coal feeder body, a feeding pipe and a discharging pipe, the outer sides of conveying rollers are movably connected with a conveying belt, a knocking mechanism is installed in the conveying belt, one end of one conveying roller penetrates through the side wall of the coal feeder body, extends to the outside and is connected with a first motor, and a dredging assembly is arranged below one side in the coal feeder body. By means of the knocking mechanism, the conveying belt can be knocked in a reciprocating mode, coal scraps adhering to the surface of the conveying belt can be shaken off, the daily cleaning effect of the conveying belt is guaranteed, the situation of mechanical faults is reduced, the arranged dredging assembly can extrude coal accumulated in the discharging pipe back and forth, the coal can be rapidly discharged to the outside, and the conveying belt can be cleaned conveniently. The phenomenon that the discharging pipe is blocked is reduced, the feeding efficiency and continuity of the coal feeder are improved, and the conveying progress of coal is accelerated.

Description

technical field [0001] The invention relates to the field of coal feeders, in particular to a coal feeder with an anti-clogging function. Background technique [0002] The coal feeder is a kind of mechanical equipment that can accurately adjust the coal feeding amount of the coal mill according to the load requirements. It is arranged between the raw coal hopper and the coal mill. In the direct-blown pulverizing system, the amount of coal fed is directly adapted to the boiler load. [0003] According to the findings of the inspection institute, the Chinese patent with the patent number CN202120907651.4 discloses a coal feeder device, which is closed by the first valve, and then the first valve can be opened to avoid the work of the high-temperature flue gas escaping from the furnace. Adding bed material to the environment reduces the difficulty of operation, improves the operation environment, and eliminates the safety risk of belt fire caused by high-temperature flue gas e...
