[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] A central column structure for buffering height difference of falling materials comprises a central column 1, which is an upright cylindrical structure, a discharge chute 2 is connected to the inner surface of the central column 1, and the discharge chute 2 rises spirally along the inner surface of the central column 1, and a plurality of discharge windows 3 are arranged in the side wall of the central column 1, and the plurality of discharge windows 3 are arranged in the vertical direction, such as Figures 1 to 3 shown.

[0024] During unloading, the raw materials fall from the top of the central column 1 into the upper end of the unloading chute 2. The unloading chute 2 has a spiral structure as a whole. The raw materials slide or roll along the inner surface of the unloading chute 2 to the bottom of the central column 1 and begin to accumulate naturally. In this process, the raw materials avoid the impact caused by direct falling, thereby reducing the breakage rate of the raw materials.

[0025] In this embodiment, the central column 1 is a cylindrical structure, the axis of the central column 1 coincides with the axis of the discharge chute 2, and the central column 1 can be made of metal or concrete. The outer side of the discharge chute 2 matches and is connected to the inner surface of the central column 1. Figure 2 As shown, the spiral angle of the discharge chute 2 is 40°-70°, and different angles can be considered according to the type of material.

[0026] In this embodiment, the lower end of the discharge chute 2 can be connected to the ground, and the inner surface of the central column 1 can be connected to one or more discharge chutes 2. When the inner surface of the central column 1 is connected to multiple discharge chutes 2, the multiple discharge chutes 2 are evenly spaced along the circumference of the central column 1, that is, the discharge chute 2 is similar to the spiral line of the multi-start thread surface to improve the discharge efficiency.

[0027] In this embodiment, the cross section of the discharge chute 2 can be concave, such as Figure 4 Alternatively, the cross section of the discharge chute 2 may also be L-shaped, as shown in FIG. Figure 5 As shown. The discharge chute 2 can also be made of metal or concrete structure. The discharge chute 2 is fixedly connected to the central column 1.

[0028] In this embodiment, the cross-sectional width of the discharge chute 2 can be 0.6m-1.2m, the cross-sectional height of the discharge chute 2 can be 0.4m-1m, and the cross-sectional dimensions of the discharge chute 2 can be considered in different sizes according to the discharge capacity. In order to reduce the impact and wear of the material on the discharge chute 2, the inner surface of the discharge chute 2 can be provided with a rubber cushion layer to increase the service life of the discharge chute 2.

[0029] In this embodiment, the upper end of the central column 1 can be a closed or semi-closed structure, and a feeding funnel 5 is provided in the upper end of the central column 1, and the lower end of the feeding funnel 5 is arranged correspondingly to the upper end of the discharge chute 2. The material first enters the feeding funnel 5 and then enters the discharge chute 2.

[0030] In this embodiment, the discharge windows 3 are arranged in regular rows (layers), and the discharge windows 3 are arranged in a vertical direction to form a plurality of discharge window layers 4, and each discharge window layer 4 contains a plurality of discharge windows 3. Figure 3 As shown, the discharge windows 3 are arranged to form 5 layers and 4 columns.

[0031] Specifically, along the vertical direction, the discharge window layers 4 are arranged on the central column 1 to form 5 discharge window layers 4, and each discharge window layer 4 contains 4 discharge windows 3. The lower ends of the discharge windows 3 in the lowest discharge window layer 4 are connected to the ground, such as Figure 1 and Figure 3 shown.

[0032] In this embodiment, the inner diameter of the central column 1 can be 5m-10m, the width of the discharge window 3 can be 0.5m-1.2m, the height of the discharge window 3 can be 0.5m-1.2m, and the size of the discharge window 3 can be different according to the type of material and the discharge capacity. The shape of the discharge window 3 can be rectangular, circular, hexagonal, etc.

[0033] In this embodiment, in order to prevent the material from sliding or rolling down the discharge chute 2 and flying out of the discharge window 3 prematurely, a lifting baffle is provided at the discharge window 3, which can open or close the discharge window 3.

[0034] Preferably, the discharge window 3 connected to the discharge chute 2 is provided with a lifting baffle, and the discharge window 3 not connected to the discharge chute 2 has no lifting baffle. The lifting baffle can be set on the inner side or the outer side of the discharge window 3, and each of the lifting baffles can be independently controlled to rise and fall as needed.

[0035] The following describes a material storage warehouse, which includes a closed warehouse 6 and the above-mentioned central column structure for buffering the height difference of falling materials. The lower part of the central column structure for buffering the height difference of falling materials is located in the closed warehouse 6. Figure 6 shown.

[0036] The closed warehouse 6 is basically the same in structure as the existing silo or circular material storage type. The axis of the central column 1 coincides with the axis of the closed warehouse 6. The upper end of the central column 1 can be located inside the closed warehouse 6 or outside the closed warehouse 6.

[0037] The following introduces the working process of the central column structure for buffering the height difference of falling materials and the storage warehouse.

[0038] Raw material unloading: The raw material is sent to the feeding hopper 5 at the top of the central column 1 by a conveyor or other carrying equipment, and the unloading begins.

[0039] Raw material buffering falls: the raw material enters the discharge chute 2 from the feeding funnel 5, and the raw material flows along the discharge chute 2 to the bottom of the central column 1 and begins to be naturally stored; the raw material flows downward on the inner surface of the discharge chute 2, which reduces the falling speed and the height difference impact force, thereby reducing the crushing rate.

[0040] The raw materials are naturally stored at the first discharge window layer 4 from the bottom to the top. The raw materials overflow from the discharge window 3 of the discharge window layer 4 to the outside of the central column 1 and are naturally stored around the central column 1 in the storage area. At this time, the drop and impact force of the raw materials are the largest, and will gradually decrease thereafter.

[0041] The raw material stacking height is increased once: the raw materials are stacked at their natural stacking angles. After the discharge window 3 of the discharge window layer 4 is full and no more raw materials overflow, the raw materials are stacked in the central column 1 with the height increasing continuously. As the stacking height increases, the height difference of the falling materials can be reduced in the column.

[0042] Secondary natural stockpiling of raw materials: When the material pile height in the central column 1 increases to the second discharge window layer 4 from the bottom to the top, the raw materials overflow from the discharge window 3 of the discharge window layer 4 outside the central column 1, and naturally stockpile around the central column 1 in the storage area, and fall on the top of the pile formed by the first discharge window layer 4 from the bottom to the top, and the drop is cut off by layer, thereby achieving deceleration and reducing the impact force;

[0043] The raw material storage height is increased twice: the raw materials are stored at their natural stacking angles. After the second discharge window layer 4 from the bottom is full and no raw materials overflow, the raw materials are stored in the central column 1, and the height continues to increase;

[0044] Raw materials are fully stacked: when the raw materials are alternately naturally stacked and the stacking height is increased until the height reaches the uppermost discharge window layer 4 (i.e., the fifth discharge window layer 4 from the bottom to the top), the raw materials are fully stacked in the storage bin.

[0045] The above is only a specific embodiment of the present invention, and cannot be used to limit the scope of the invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the protection scope of the present invention, should still fall within the scope of this patent. In addition, the technical features of the present invention can be freely combined with each other, with technical features and technical solutions, and with technical solutions.
