Problems solved by technology

However, this primitive method quickly deforms and damages the blanking cylinder
At present, some manufacturers address this problem by installing an air cannon on the drop pipe, and using the air cannon to explode and dredge the clogged material. This method will generate a lot of noise, cause dust, and there are potential dangers.

Abstract

The invention discloses an unpowered self-driven type coal hopper anti-blocking device, relating to a blocking prevention and dredging device of the coal hopper. A first connecting sleeve (14) and a first sleeve (6) of the device are connected to form a revolute pair; an upper dead lever is fixedly connected with a coal hopper wall (2) by an upper fixed plate (11); a first oscillating bar (5) is welded and fixedly connected with a trepan boring (4) of a connecting casing pipe; a second sleeve (8) and a second connecting sleeve are connected to form the revolute pair; a third sleeve (23) and athird connecting sleeve (35) are connected to form the revolute pair; a parallelogram mechanism is fixedly connected with the coal hopper wall (2) by a lower fixed plate (49); when coal sheets fall down from the top of the coal hopper, the coal sheets strike a cone-shaped stainless steel anti-impact cap(1), the anti-impact cap component drives a blockage clearing rod on the parallelogram mechanism to up and down move by the oscillating bar component and the connecting rod component to realize the blocking prevention and dredging of the coal hopper.

Description

technical field [0001] The invention relates to a blockage prevention and dredging device for a coal hopper, which is suitable for raw coal hoppers in power plants and other occasions with a large amount of material flow. Background technique [0002] The raw coal drop hopper of thermal power plant is an important equipment for the coal conveying system to convey coal to the boiler combustion system. Its structural shape is basically the same, the upper part is cylindrical and the lower part is conical. The upper port is large and the lower port is small, and the upper port is fed with raw materials, and the raw coal falls from top to bottom by its own weight. The fallen raw coal enters the coal mill through the coal feeder and is finally sent to the combustion chamber. In the actual operation process, the equipment generally has a serious problem of blanking blockage. The blockage of the coal hopper will bring serious consequences such as downtime or waste of heavy oil. ...
