[0016] For the convenience of understanding and implementing the present application, the preferred embodiments of the present application are further described in conjunction with the accompanying drawings.

[0017] As shown in Figures 1 to 3 The present application comprises a bottom 1 with a conical inner cavity with a large end upward and a small end downward, the upper end of the conical inner cavity is an inlet, the lower end is an outlet, a valve is installed on the outlet, the lower part of the bottom 1 is fixedly provided with a supporting leg 9, one or more hollow conical walls 2 are installed above the bottom 1 in a vertical direction, the large end of the conical wall 2 is upward, and the small end is downward; the lower end of the lowest conical wall 2 extends into the bottom 1 (i.e. the lower end surface position of the conical wall 2 is lower than the upper end surface position of the bottom 1), and there is a set distance between the outer side wall of the lower end of the conical wall 2 and the inner side wall of the upper end of the bottom 1; the bottom 1 and the conical wall 2 are fixedly connected through the supporting connecting pieces arranged along the circumference of the bottom 1; the connecting structure between the adjacent two conical walls 2 is the same as the connecting structure between the bottom 1 and the conical wall 2. The adjacent two conical walls 2 are respectively set as an upper conical wall and a lower conical wall, the "upper conical wall" is equivalent to the "lowest conical wall 2" described above, and the "lower conical wall" is equivalent to the "bottom 1" described above. The specific connecting structure is as follows: the lower end of the upper conical wall extends into the lower conical wall (i.e. the lower end surface position of the upper conical wall is lower than the upper end surface position of the lower conical wall), and there is a set distance between the outer side wall of the lower end of the upper conical wall and the inner side wall of the upper end of the lower conical wall; the lower conical wall and the upper conical wall are fixedly connected through the supporting connecting pieces arranged along the circumference of the lower conical wall. Among them, the supporting leg 9 is generally three or four uniformly spaced, the main purpose of which is to support and fix the silo, and to make the outlet suspended to facilitate discharging. In implementation, the supporting leg 9 and the ground or mounting platform are fixedly connected.

[0018] As shown in Figure 1 When the material enters from the top of the silo and falls into the bottom 1 and naturally accumulates, a cavity structure will be formed in the outer edge area of the inner cavity at the top of the bottom 1, and similarly, a cavity structure will be formed in the outer edge area of the inner cavity at the top of each layer of conical wall 2, and the supporting connecting pieces are arranged along the circumference of the bottom 1, and the area between the adjacent two supporting connecting pieces forms an interval channel that can be connected to the outside of the silo, and the above cavity structure and interval channel constitute a material ventilation and respiration channel, and each layer of material has a relatively large ventilation and respiration surface (at least a ventilation and respiration surface can be formed in the outer ring area at the top of each layer of material). Therefore, the present application can increase the pressure relief area, increase the stacking height of dangerous solid particles, increase the ventilation and respiration surface of the material, which is beneficial to dissipate the heat generated by the material accumulation and reduce the temperature of the material, and at the same time, can increase the water injection area of the fire rain shower, and improve the safety of the stored material.

[0019] In order to make the circumferential material ventilation breathing channel distribute uniformly, preferably, the conical bin wall 2 and the bin bottom 1 are coaxially arranged.

[0020] It can be understood that the conical inner cavity of the conical bin wall 2 and the conical inner cavity of the bin bottom 1 should be matched, and the inner cavity radial section thereof can be a polygonal structure, for example, a common rectangular structure. In order to facilitate the flow of materials, preferably, the inner cavity radial section of the conical bin wall 2 and the inner cavity radial section of the bin bottom 1 are both circular.

[0021] It can be understood that the support connecting pieces between the conical bin wall 2 at the lowest level and the bin bottom 1 are a group, one end of which can be fixedly connected to any position of the outer side wall of the bin bottom 1, and the other end of which can be fixedly connected to any position of the outer side wall of the conical bin wall 2, as long as the conical bin wall 2 can be stably supported. Similarly, the support connecting pieces between the two adjacent conical bin walls 2 are a group, and each support connecting piece also has no special technical requirements, as long as each conical bin wall 2 can be stably supported. The two ends of the support connecting piece can be fixedly connected to the corresponding positions by welding, riveting, bolt connection and the like.

[0022] In order to facilitate connection, preferably, the outer side wall of the bin bottom 1 and the outer side wall of the conical bin wall 2 are both fixedly provided with an ear plate or a ring-shaped mounting plate for fixedly connecting the support connecting piece.

[0023] In order to support firmly and reliably, the support connecting piece is generally vertically arranged, in order to realize quick assembly and disassembly, the support connecting piece comprises coaxially arranged upper connecting head 3 and lower connecting head 4, the upper connecting head 3 and the lower connecting head 4 are connected through the embedded structure of the matching of the protrusion and the groove on the end face of the two opposite interfaces (that is, in the two components of the upper connecting head 3 and the lower connecting head 4, one is arranged with protrusion at the end face position, and the other is arranged with groove at the end face position, the positions of the protrusion and the groove can be interchanged), and the upper connecting head 3 and the lower connecting head 4 are connected together through the pin 5 at the matching position of the protrusion and the groove. When assembling, after the upper connecting head 3 and the lower connecting head 4 are aligned and inserted into position, the pin 5 is inserted. When disassembling, the pin 5 at the corresponding position is pulled out. Further preferably, for the same group of support connecting pieces, the end of the upper connecting head 3 away from the lower connecting head 4 is connected and fixed on the conical bin wall 2 through the threaded rod connecting end head matched with the nut 8; the end of the lower connecting head 4 away from the upper connecting head 3 is connected and fixed on the conical bin wall 2 or the bin bottom 1 through the threaded rod connecting end head matched with the nut 8. It can be understood that after the structure of the threaded rod connecting end head matched with the nut 8 is adopted, bolt connection holes need to be arranged on the corresponding ear plates or annular mounting plates. The conical bin wall 2 located in the middle needs to be arranged with the lower connecting head 4 for connecting the upper adjacent conical bin wall 2 and the upper connecting head 3 for connecting the lower adjacent conical bin wall 2. In order to avoid interference between the upper connecting head 3 and the lower connecting head 4, the two can be arranged in a staggered manner. For example, for the same conical bin wall 2, eight bolt connection holes can be designed to be uniformly distributed in a circle, wherein four bolt connection holes distributed in a cross shape are used to connect the upper connecting head 3, and the other four bolt connection holes are used to connect the lower connecting head 4. After the structure of the threaded rod connecting end head matched with the nut 8 is adopted, the upper connecting head 3 and the lower connecting head 4 can be disassembled, so that the overlapping stacking of the conical bin walls 2 can be facilitated, thereby facilitating packaging and transportation after manufacturing, and assembly is also extremely convenient during use. In addition, in order to make the connection structure more stable, the nut 8 can be used in cooperation with the gasket 7.

[0024] Preferably, the outer periphery of the laminated bin is provided with a protective net 6 distributed in a ring shape, the upper end of the protective net 6 is fixedly arranged on the upper part of the outer side wall of the uppermost conical bin wall 2, and the lower end of the protective net 6 is fixedly arranged on the upper part of the outer side wall of the bin bottom 1. The upper and lower ends of the protective net 6 are preferably fixed in a detachable manner, such as bolt fixing, pin fixing, binding fixing, etc. Of course, in order to make the connection more stable, other connection fixing points can also be added on the conical bin wall 2 located in the middle. After the conical bin wall 2 is assembled and reaches the required bin capacity, the protective net 6 is installed and fixed on the outer side wall of the bin. When disassembling, the protective net 6 is first removed, and then the pin 5 at the corresponding position is pulled out, so that the conical bin wall 2 can be disassembled. The protective net 6 prevents small animals such as mice from entering the bin through the material ventilation and breathing channel of the outer side wall of the bin.
