Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The design scheme of the invention is explained in detail by taking a steel structure cylindrical aggregate bin with the diameter of 16m as an example: discharge opening 5 is established to 1 bottoms of circular cylinder, and 5 hole weeks in discharge opening are equipped with inclined plane guide plate 2, and this inclined plane guide plate 2 upper end and 1 inner wall rigid coupling of cylinder, lower extreme and 5 marginal rigid couplings of discharge opening, 2 downside on the inclined plane guide plate are equipped with bearing structure 4.

The silo cylinder body of the invention adopts Q235 (or Q345) common carbon structural steel or low alloy steel, and the thickness of the steel plate can be determined according to the type calculation of the aggregate. The plate is firstly made into a semicircular or sectional type cylinder with the height of 2-3 m on a steel structural member, and then is transported to a construction site to be welded and connected into the cylinder.

The cylindrical aggregate bin provided by the invention is provided with a passive arch breaking structure, and particularly, as shown in figures 1-3, the arch breaking structure is a plurality of steel pipes 3 arranged on an inclined plane guide plate 2. The steel pipe 3 is horizontally arranged, the inner end of the steel pipe 3 is fixedly connected with the inner wall of the bin cylinder body 1, the steel pipe body is fixedly connected with the supporting structure 4, and the outer end of the steel pipe penetrates through the inclined plane guide plate 2; the steel pipe 3 is fixedly connected with the intersected node of the inclined guide plate 2 in a full-welding mode, and the length of the steel pipe 3 exposed out of the surface of the inclined guide plate 2 is 20-25 mm.

The arch breaking structure is arranged on the discharging path, transversely cuts the descending path of the aggregate, acts on the agglomerated aggregate during discharging, and cuts and destroys agglomerates of the material by the steel pipe in the vertical descending process of the aggregate to loosen the stable stacking structure.

The inclined plane guide plate 2 structure, the guide plate support structure 4 and the arch breaking structure are all arranged in the cylinder body, and belong to the internal structure of the bin. All structures bear the vertical load from the aggregate in the silo, so that each structural member must be designed to have sufficient strength.

For example, the material of the inclined guide plate 2 structure can be common carbon structural steel or low alloy steel of Q235 (or Q345), and the thickness of the steel plate can be determined according to the type of aggregate. The steel plate of the inclined guide plate 2 is required to be a smooth and flat steel plate without concave-convex textures on the surface. Steel sheets with increased friction, such as textured steel sheets, are not used because they reduce the downward movement rate of the aggregates.

The supporting structure 4 is a steel frame structure welded by 10# channel steel. The supporting structure 4 comprises a guide plate which is parallel to the inclined plane and is formed by welding horizontal channel steel and vertical channel steel, and a # -shaped frame surface 41 tightly attached to the bottom surface of the guide plate. The wing plate direction of the horizontal channel steel is welded and connected with the bottom surface of the inclined plane guide plate 2 structure; and the web plate direction of the vertical channel steel is welded and connected with the bottom surface of the inclined plane guide plate 2 structure. The upper end of the # -shaped frame surface is welded and fixed with the inner wall of the bin barrel 1, and the lower end is welded along the edge of the discharge opening. The channel-section steel # -shaped frame face plays the planar effect of support inclined plane guide plate 2, simultaneously because channel-section steel atress characteristic for by channel-section steel welded connection's # -shaped frame face have sufficient compressive capacity, can provide compressive capacity's support for guide plate structure by the at utmost.

The inclined plane guide plate 2 and the supporting structure 4 are designed to have a slope angle of 50 degrees and incline from the cylinder wall to the middle discharge opening. The inclination angle of 50 degrees can decompose the vertical action of the aggregate into vertical stress and horizontal stress, the horizontal stress gradually pushes the aggregate towards the direction of the discharge opening 5 along with the vertical stress action of the aggregate, and the vertical stress is reduced along with the decomposition of the stress action. The inclined plane guide plate 2 structure transmits the borne force to the supporting structure 4, and then the borne force is transmitted to the cylindrical barrel 1 and the ground through the supporting structure 4.

The arch breaking structure adopts hollow steel pipes, the material of the arch breaking structure is common carbon structural steel or low alloy steel pipes, and the nominal diameter of the steel pipes is phi 133 mm. Each steel pipe 3 is connected with the inner wall of the cylinder through a steel base plate, and the contact area of the steel base plate is increased so as to improve the stability and rigidity of the arch breaking structure and the cylinder body 1 of the cylinder. The axial compression resistance and the lateral limit compression resistance of the hollow steel pipe are greater than those of the solid steel pipe, and the strength of the used material can effectively meet the stress requirement of the structural member.

The steel pipe with the arch breaking structure is preferably arranged in the direction vertical to the blanking direction, ① axes shown in figures 1, 2 and 6 are central lines at the left side and the right side of the cylinder body,

the axis is the central line of the front and the rear sides, and each steel pipe 3 is arranged according to ① axis orThe axes are symmetrical two by two. In this example, the steel tubes of the arch-breaking structure are arranged horizontally on the supporting structureThe upper part and the lower part are fixedly connected with two layers. Under general conditions, the intersection point position of the front end of the steel pipe and the inclined plane guide plate extends forwards by 20-25 cm to meet the functional requirement.

Further, as shown in fig. 4, a fork tooth structure 6 is arranged at the front end of the steel pipe 3, and the tip of the fork tooth structure 6 is tilted upwards. The upturned tip penetrates more easily into the knot body. The upward fork teeth are matched with the downward flow force of the aggregate to extrude and knead the aggregate, so that hard blocks in the aggregate are crushed and loosened.

In the example provided by the invention, the bin is provided with two parallel discharge openings 5. The inclined plane guide plate 2 and the arch breaking structure can be arranged between the two discharge openings 5. Specifically, as shown in fig. 5 and 6, a support frame 42 is disposed on the center line between the two discharge openings 5, and the top of the support frame 42 is fixedly connected to the edge of the discharge opening 5 by a # -shaped frame surface 41 and an inclined guide plate 2. The support frame 42 and the framework surface 41 both belong to the support structure 4 of the guide plate, so that a triangular support framework is formed between the two discharge openings, the vertices of which intersect on the (r) axis shown in the figure. Still according to the setting rule of the arch-breaking structure, two layers of arch-breaking steel pipes 3 are welded on the upper part and the lower part of the side # -shaped frame surface 41, and two ends of each steel pipe 3 respectively penetrate through the inclined plane guide plates 2 on two sides. When a stable structure is formed, the shape of the aggregate stacked compact body is damaged, so that the aggregate stacked compact in the central area of the cylinder body is gradually damaged under the action of gravity.

The bottom structure of the cylindrical aggregate bin provided by the invention not only can effectively destroy aggregate accumulated compact bodies, but also can effectively bear and decompose aggregate and loads generated by interaction with the aggregate accumulated compact bodies, and the cylinder body, the supporting structure, the inclined plane guide plate and the arch breaking structure are combined into a whole.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
