[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] The following combination Figure 1 , describing the embodiments of the present utility model.

[0028] According to an embodiment of the present invention, on the one hand, a silo structure is provided, comprising:

[0029] The silo 1 is suitable for accommodating materials. Along the gravity direction, the silo 1 accommodates a variety of materials. The bottom of the silo 1 is provided with a discharge port 104, which is suitable for communicating with a material device.

[0030] At least one connecting pipe 2, one end of which is connected to the side wall of the silo 1 corresponding to the position of different materials and is connected to the interior of the silo 1, and the other end is connected to the material device. The connecting pipe 2 has a connecting state that allows materials to pass through, and a closed state that prevents materials from passing through.

[0031] The silo structure provided in this embodiment has a silo 1 that accommodates a variety of materials along the direction of gravity, and a connecting pipe 2 is provided at the position corresponding to different materials, so that the connecting pipe 2 can be controlled to switch between the connected state and the closed state as needed, thereby realizing the provision of different types of materials to the material-using device and improving the flexibility of replacing materials.

[0032] Specifically, the silo 1 has a receiving chamber for accommodating materials, and multiple materials are distributed in the receiving chamber along the direction of gravity, and two adjacent materials are in direct contact. When the number of connecting pipes 2 is multiple, at least two connecting pipes 2 are spaced apart in the height direction. The discharge port 104 has an open state that allows materials to pass through, and a blocked state that prevents materials from passing through. When the silo 1 is initially filled with materials, the discharge port 104 is in a blocked state, and different types of materials are filled into the silo 1 in turn, and the connecting pipe 2 and the discharge port 104 correspond to different types of materials respectively. When a specific type of material is needed, the discharge port 104 or the connecting pipe 2 at the corresponding position is opened to provide the specific type of material to the material-using device.

[0033] After one type of material is completely discharged through the discharge port 104 or the connecting pipe 2, the material or the required type of material can be continuously filled at the feed port 103. In addition, by filling a plurality of materials into a silo 1, when the types of required materials are fixed, the number of silos 1 required can be reduced, and when the number of silos 1 is fixed, more types of materials can be stored.

[0034] In one embodiment, the silo structure further includes a material position detection system, which is suitable for detecting the relative positions of different types of materials and the silo 1 .

[0035] The silo structure provided in this embodiment detects the relative positions of different types of materials in the silo 1, so that the operator can refer to the position of the required material and purposefully open the connecting pipe 2 corresponding to its position, thereby improving operability.

[0036] In one embodiment, combined Figure 1 As shown, the material position detection system includes a material type detection device 8, a feed metering device 9, a discharge metering device, a processor and a display. The material type detection device 8 and the feed metering device 9 are arranged at the feed port 103 of the silo 1, and the discharge metering device is arranged at the material device;

[0037] The material type detection device 8, the feed metering device 9 and the discharge metering device are electrically connected to the processor, and the processor is electrically connected to the display so as to be suitable for displaying the positions of different types of materials in the silo 1 on the display.

[0038] The silo structure provided in this embodiment displays the relative positions of different materials on a display, so that operators can intuitively observe the relative positions of different types of materials and the connecting pipe 2.

[0039] Specifically, the corresponding material type detection equipment 8, feed metering equipment 9 and discharge metering equipment are selected according to the type of material actually filled. For example, taking the filling of coal of different coal qualities as an example, the material type detection equipment 8 is selected as the coal quality detection equipment, and the feed metering equipment 9 and the discharge metering equipment are selected as the coal quantity metering equipment and coal quantity inspection equipment respectively.

[0040] A material type detection device 8 and a feed metering device 9 are provided at the feed port 103 to detect the order and volume of the various materials filled into the feed bin 1. The material type detection device 8 and the feed metering device 9 are electrically connected to the processor to transmit information about the order and volume of the various materials entering the feed bin 1. A discharge metering device is provided at the feed device to detect the discharge volume of the material. The discharge metering device is electrically connected to the processor to transmit information about the discharge volume of the material to the processor.

[0041] The processor pre-stores the shape and size information of the accommodating cavity of the silo 1, as well as the position information of the connecting pipe 2 on the silo 1. After calculation and analysis by the processor, the relative positions of various materials with the silo 1 and the connecting pipe 2 are obtained, and these data are used to generate a visual dynamic model of the flow of different materials and their positions on the display screen, so that the positions of various materials can be seen at any time, thereby providing convenience for guiding the operator's operation.

[0042] In some embodiments not shown, at least one material type detection device 8 is provided on the inner wall of the silo 1 at a position corresponding to the inlet of each connecting pipe 2. The material type detection device 8 is electrically connected to the display so as to be suitable for displaying the material type at the inlet of each connecting pipe 2 on the display, thereby facilitating the operator to open or close the corresponding connecting pipe 2 as needed.

[0043] In one embodiment, the material position detection system further includes a material position checking device, which is disposed on the top of the silo 1 and is suitable for checking the falling distance of the material inside the silo 1 .

[0044] The silo structure provided in this embodiment is conducive to improving the accuracy of the display by arranging a material position inspection device on the top of the silo 1 to detect the falling distance of the material, so as to verify the data obtained by the feed metering device 9 and the discharge metering device.

[0045] Specifically, the material position inspection device is used to detect the height of the uppermost material in the silo 1 and is electrically connected to the processor to transmit the height information of the material falling to the processor so that the processor can verify the results of its analysis and calculation.

[0046] In one embodiment, combined Figure 1 As shown, a first valve 3 is provided on the connecting pipe 2 , which is suitable for controlling the connecting pipe 2 to switch between a connected state and a closed state through the first valve 3 .

[0047] In one embodiment, combined Figure 1 As shown, a second valve 4 is provided at the discharge port 104 to allow or prevent the material from passing through the discharge port 104 and entering the material-consuming device.

[0048] In one embodiment, combined Figure 1 As shown, a material delivery pipe 6 is connected between the discharge port 104 and the material using device, so as to be suitable for introducing the material in the silo 1 into the material using device.

[0049] In one embodiment, combined Figure 1 As shown, the other end of the connecting pipe 2 is connected to the material conveying pipe 6.

[0050] In some implementations not shown, a plurality of inlets may be provided on the material-consuming device, so that the discharge port 104 and the connecting pipe 2 are respectively connected to the material-consuming device.

[0051] According to an embodiment of the present invention, on the other hand, a coal bunker feeding system is provided, comprising: the above-mentioned bunker structure, wherein the accommodating cavity thereof is suitable for storing coal, and the feeding device is configured as a boiler.

[0052] Specifically, at least one silo structure is connected to the boiler. When multiple silo structures are connected to the boiler, different silos can output coal of different qualities, enabling blending of different coal qualities and supplying them to the boiler. In actual operation, thermal power plants frequently participate in grid peak regulation, requiring timely changes in coal quality to meet the boiler's needs for grid peak regulation. The coal silo feeding system provided by this embodiment can increase the flexibility of coal supply from the silo, thereby improving the ability of thermal power generators to participate in grid peak regulation in related technologies and meeting the urgent needs of the power market.

[0053] For example, silo 1 stores two types of coal, namely, first type coal 101 and second type coal 102. The first type coal 101 and second type coal 102 are sequentially loaded into silo 1 through feed port 103. The first type coal 101 is adapted to enter the feeding device through discharge port 104, while the second type coal 102 is adapted to enter the feeding device through connecting pipe 2, allowing for the replacement of the coal quality supplied to the feeding device as needed. After the first type coal 101 is completely discharged through discharge port 104, silo 1 can be filled with the first type coal 101 so that the first type coal 101 is positioned above the second type coal 102. At this point, the second type coal 102 enters the feeding device through discharge port 104, while the first type coal 101 enters the feeding device through connecting pipe 2, allowing for a cyclical use.

[0054] In one embodiment, combined Figure 1 As shown, the coal bunker feeding system further includes a coal feeder 5, which is arranged between the bunker structure and the boiler, and is suitable for conveying the coal in the bunker structure to the boiler.

[0055] Specifically, the discharge port and connecting pipe 2 of the silo 1 are directly connected to the coal feeder 5, or are connected to the inlet of the coal feeder 5 through a conveying pipe 6. The coal feeder 5 has a coal feeder outlet 501, which is connected to the boiler. A conveyor belt 7 is installed inside the coal feeder 5, with one end located below the inlet of the coal feeder 5 and the other end located above the coal feeder outlet 501. The conveyor belt 7 is suitable for conveying coal entering from the inlet of the coal feeder 5 to the coal feeder outlet 501 and dropping it into the boiler.

[0056] Obviously, the above embodiments are merely examples for the purpose of clarity of explanation and are not intended to limit the implementation methods. Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
