Our company has applied for a patent. Patent name: a loose buffer anti-blocking coal bunker. Patent No.20 1720699728.7
The buffering loose anti-blocking coal bunker is divided into several sections in turn at the bottom of the coal bunker which is easy to be blocked, and each section is added with a buffering loose block, the buffering loose block consists of an upper surface and a lower surface, the upper surface is used to bear the impact force and gravity when the raw coal falls, and the lower surface is used to reduce the included angle between the lower surface of this section and the opposite coal bunker wall, so that the included angle between the lower surface and the opposite coal bunker wall can form an upright triangle, and the lower the raw coal flow, the looser the raw coal in the coal bunker.
The inner wall of the buffer loose anti-blocking coal bunker is composed of a plurality of buffer loose blocks, which are arranged in layers from bottom to top. The lower surfaces of the buffer loose blocks are closely connected in layers from bottom to top. The buffer loose block consists of an upper surface and a lower surface. The upper surface is used to bear the gravity and impact of raw coal and keep the raw coal in a flow-blocking state that is not easy to accumulate, and the included angle with the horizontal plane is about 45 degrees. The lower surface is used to reduce the included angle with the opposite silo wall, so that the raw coal circulation space becomes larger and larger. Negative pressure vent holes are left at the top and bottom of the buffer loose block.
Buffer movable blocks can be installed in coal bunker with the following shapes, such as conical coal bunker, hyperbolic coal bunker, eccentric conical coal bunker, irregular coal bunker, square conical coal bunker or eccentric square conical coal bunker; At the same time, the buffer loose block can also be installed in the coal inlet of the coal mill and other parts that are easy to be blocked.
The buffering loose anti-blocking coal bunker provided by the utility model completely solves the phenomenon of coal blocking and blocking caused by the size change of raw coal bunker and conveying pipeline, and provides an economical and practical scheme for solving the anti-blocking transformation of existing raw coal bunker. The anti-blocking transformation is more convenient and the cost is lower, which makes the material transportation of coal bunker smoother.
Buffer loose anti-blocking coal bunker has the following advantages:
1: The cost is low, and 4 ~ 5 stainless steel buffer loose blocks are welded at the position where the coal bunker is easy to be blocked.
2: the structure is firm, not easy to fall off, stainless steel is wear-resistant and smooth, not easy to bond, not rusty, and has a long service life.
3: No maintenance, long-term enjoyment.
4. The anti-blocking range is not limited, and the anti-blocking can be completely solved at any other position of 4 meters, 5 meters, other heights and from big to small.
Even all kinds of inferior raw coal, no matter how high the moisture is, will not be blocked.
