Description

TECHNICAL FIELD

[0001] The utility model belongs to coal bunker accessory technical field relates to a device for coal bunker, specifically is a device for coal bunker unblocking. BACKGROUND

[0002] The upper part of the traditional coal bunker is a large-aperture concrete structure, and the lower part is a hyperbolic steel structure. Since the upper part of the bunker has a large aperture, the half-aperture of the lower part of the hyperbolic taper will be too large, which will slow down the flow of raw coal. In addition, the inner wall of the bunker body is prone to sticking material, which will slow down the flow of raw coal through the middle and lower parts of the coal bunker, increase the resistance, and cause the accumulation and sticking of raw coal, resulting in the phenomenon of blockage and flow interruption. When the coal has high water content, the agglomeration of the coal will increase, and the blockage and flow interruption will be more serious.

[0003] The traditional solution is to install an air cannon in the lower part of the coal bunker. However, the air cannon can only be installed at a certain point on the side wall of the coal bunker, which is a fixed-point passive unblocking. With the flow of raw coal, the sticking and blocking points of the coal on the bunker wall are constantly changing, and the air cannon cannot effectively dredge the sticking coal on the bunker wall, so it cannot effectively solve the problem of sticking and blocking coal.

[0004] In addition, when the coal does not flow smoothly in the tapered taper section, the accumulated coal in the taper will not be transported out, and the air cannon will instead become more solid, which will cause the coal to stop flowing. After the interruption, manual unblocking methods are needed, such as using a steel drill to stick coal from the opening of the bunker wall, or workers using a sledgehammer to knock the bunker wall from the outside of the bunker body. These measures are not ideal for solving the problem of sticking and blocking coal, and the manual unblocking method not only requires a lot of labor, but also has many safety hazards.

[0005] Therefore, it is necessary to provide a device to solve the problem of easy sticking and blocking of coal in the traditional coal bunker. UTILITY MODEL CONTENTS
