[0002] Currently, thermal power has gradually transitioned into peak-shaving power sources. The peak-to-valley difference in electricity load is constantly widening, making the grid's demand for peak-shaving power sources increasingly urgent. The current practice of storing only one type of coal in a single coal storage facility cannot adapt to rapid changes in electricity load. Utility Model Content

An outer stiffening rib is provided on the outside of the raw coal bunker wall panel. A partition horizontal frame and a partition vertical frame are provided inside the raw coal bunker wall panel. The position of the partition horizontal frame corresponds to the position of the outer stiffening rib.
[0006] The horizontal partition frame is arranged in multiple layers along the longitudinal direction of the coal bunker from top to bottom, and each layer is arranged with multiple horizontal partition frames. The vertical partition frame is arranged in multiple columns, and each column is arranged with multiple vertical partition frames.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0021] A partition structure for raw coal bunkers provides a method for rapid blending of applicable fuels. By adding a partition structure to the existing raw coal bunker, two types of coal can be stored in one bunker, and the ratio of the released coal types can be adapted to the rapid peak shaving of power load.
[0022] like Figure 1 , Figure 2 As shown, a partition structure 2 is installed in the coal hopper 3, wherein, Figure 1 The middle partition structure 2 is parallel to the belt conveyor running direction 1; Figure 2 The partition structure 2 is perpendicular to the belt conveyor's running direction 1. The coal hopper 3 here is an existing coal hopper.
[0023] like Figure 1 As shown, a raw coal bunker partition structure includes a raw coal bunker wall panel 8, with an outer stiffening rib 4 on the outside of the raw coal bunker wall panel 8, and a partition horizontal frame 5 and a partition vertical frame 6 inside the raw coal bunker wall panel 8. The partition horizontal frame 5 is the main load-bearing structure, and the partition vertical frame 6 is the secondary load-bearing structure. The position of the partition horizontal frame 5 corresponds to the position of the outer stiffening rib 4.
[0024] Therefore, the horizontal partition frame 5 is arranged in multiple layers along the longitudinal direction of the coal bunker from top to bottom, and each layer is provided with multiple horizontal partition frames 5. The vertical partition frame 6 is arranged in multiple columns, and each column is provided with multiple vertical partition frames 6. The horizontal partition frame 5 and the vertical partition frame 6 form a grid structure, and the horizontal partition frame 5 and the vertical partition frame 6 are rigidly connected or hinged.
[0025] like Figure 5 As shown, in the grid area formed by the horizontal frame 5 and the vertical frame 6 of the partition, or, as... Figure 6 As shown, a hanging plate 7 is set in each of the square areas formed by the partition horizontal frame 5, the partition vertical frame 6 and the raw coal bunker wall panel 8. In this way, the partition horizontal frame 5, the partition vertical frame 6 and the hanging plate 7 constitute the main body of the partition structure.
[0026] Furthermore, within each grid area, a gap of approximately 25mm is reserved between the center line of the hanging plate 7 and the horizontal frame 5 of the partition, or between the center line of the hanging plate 7 and the vertical frame 6 of the partition, that is, the interval between two adjacent hanging plates 7 is approximately 50mm.
[0027] Furthermore, after the hanging plate 7 is welded to the raw coal bunker wall panel 8, an arc-shaped protective plate is installed at the corner.
[0028] Furthermore, the coal hopper includes an upper cylindrical section of raw coal bunker and a lower conical section of raw coal bunker, with conical stiffening ribs 9 provided in the conical section of raw coal bunker.
[0029] Furthermore, a sliding door 10 is installed at the bottom of the conical section of the raw coal bunker to facilitate the opening and closing of the two side compartments.
[0030] Furthermore, a raw coal bunker support beam 11 is provided at the bottom of the cylindrical section of the raw coal bunker, and a belt conveyor support beam 12 is provided at the top of the cylindrical section of the raw coal bunker. Both the raw coal bunker support beam 11 and the belt conveyor support beam 12 are existing structures.
[0031] A type of partition structure for raw coal bunkers can be constructed according to the following steps:
[0032] First, install the partition horizontal frame 5 inside the raw coal bunker wall panel 8. The partition horizontal frame 5 is fused to the raw coal bunker wall panel 8. The inner lining layer of the conical section of the raw coal bunker needs to be peeled off before welding.
[0033] Furthermore, install the vertical frame 6 of the partition, which needs to be rigidly or hingedly connected to the horizontal frame 5 of the partition.
[0034] Furthermore, a hanging plate 7 is installed. One hanging plate 7 is set in the grid area formed by the horizontal frame 5 of each partition and the vertical frame 6 of the partition or the raw coal bunker wall panel 8. A gap of about 25mm is reserved between the hanging plate 7 and the center line of the frame, that is, the interval between two adjacent hanging plates is about 50mm. After the hanging plate is welded to the side wall of the raw coal bunker, an arc-shaped protective plate is set at the corner. It should be noted that, in addition to leaving a gap between the hanging plates 7 and welding the fillet weld of the frame, holes can also be opened on the hanging plate 7 for plug welding or other treatment methods.
[0035] Furthermore, according to actual needs, conical stiffening ribs 9 are provided in the conical section of the raw coal bunker;
[0036] Furthermore, the existing raw coal bunker below the designated gate 10 will be removed.
[0037] It should be noted that this utility model is applicable not only to the renovation of existing raw coal bunkers, but also to the manufacture of new raw coal bunkers.
[0038] It should be noted that the shape of the raw coal bunker shown in the figure is for illustrative purposes only. In reality, it can be a raw coal bunker in various forms, such as a square bunker at the top, a conical hopper at the bottom, or a circular bunker at the top and a conical hopper at the bottom, or a hyperbolic conical hopper at the bottom.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
