Anti-blockage raw coal cabin

[0016] The present invention will be further described in detail below in conjunction with the drawings. Such as figure 1 As shown, the present invention discloses an anti-blocking raw coal bunker, which is composed of a straight cylinder section 1, a circular platform section 2, an eccentric circular platform section 3, and a movable section 7. The straight cylinder section 1, the circular platform section 2, the eccentric circular platform section 3, and the movable section 7 are all made of steel plate. The frustum section 2 and the eccentric frustum section 3 connected under the straight tube section 1 are connected by welding. The eccentric frustum section 3 is an asymmetric structure, and the angle α between the eccentric frustum section and the horizontal plane is not less than 65°. The angle β between the section wall 11 and the horizontal plane is 90°. The eccentric distance d of the eccentric frustum section 3 is not less than 30% of the radius φ on the eccentric frustum section. The asymmetric structure is adopted in the lower part of the raw coal bunker which is easy to block coal, so that when the raw coal is piled in the lower part, the supporting reaction force generated by the material is difficult to balance and automatically breaks the arch, preventing it from forming a blockage. The eccentric circular platform section 3 and the movable section 7 are connected by a short loop chain 5 for lifting. The outer wall of the movable section 7 is equipped with a vibrating motor. If a blockage occurs, the vibrating motor will start to cause a misalignment between the movable section and the fixed section above. The asymmetry of the angle of vibration wave transmission is also very effective in destroying the balance of material accumulation. Obviously, it can effectively eliminate the blockage of the silo.

[0017] The straight section 1 receives the raw coal added from the outside, the lower part of which is a tapered truncated section 2, and the truncated section 2 is provided with a raw coal bunker support structure 9. The angle α between the truncated silo wall 10 and the horizontal plane is not less than 65°.

[0018] The upper lifting lug 4 is welded on the eccentric circular platform section 3, and the lower lifting lug 6 is welded on the movable section 7. The movable section 7 is connected with the eccentric circular platform section 3 through a short lifting chain 5, which has good flexibility.

[0019] The lower part of the eccentric circular platform section 3 is sleeved into the movable section 7 to a certain depth to prevent the leakage of raw coal during vibration to meet environmental protection requirements.

[0020] In order to facilitate the operator to grasp the raw coal level, a raw coal bunker support structure 9 is provided on the round platform section 2. The raw coal bunker is supported on the platform 12 by an electronic scale. The electronic scale fulcrum passes through the cylinder section 1 hopper wall 8, and the force is reasonable. The raw coal level is measured by the weighing method, and the level measurement is reliable.

[0021] In summary, the present invention has a simple structure and is convenient to manufacture. Through the dual effects of the eccentric structure of the multi-stage bin and the external vibration, it can effectively prevent coal blocking.
