Description

Technical Field

[0001] The invention belongs to the technical field of coal-fired power feeding, and in particular relates to a coupled co-firing solid waste feeding device for a coal-fired power plant. Background Art

[0002] Coal-fired power, as an indispensable part of the power industry, is based on the principle of grinding coal into powder and burning it in the boiler of a thermal power plant. In this process, the water in the boiler absorbs the heat generated by the combustion of coal and converts it into steam with specific parameters to drive the turbine generator to generate electricity. In order to ensure that the coal powder can be stably and efficiently fed into the boiler combustion chamber, the use of a blending and feeding device is particularly important.

[0003] However, although the feeding devices on the market have met the basic needs of coal-fired power production to a certain extent, they still have many shortcomings in actual application, especially in the following aspects: Problems of solid waste adhesion and accumulation on the conveyor belt surface: In the process of conveying coal powder, the traditional feeding device is prone to adhesion of solid waste materials such as coal slag and dust on the conveyor belt surface due to the certain adhesion of coal powder itself and the electrostatic effect that may be generated during the transmission process. These solid waste materials not only affect the normal transmission of coal powder, but also may cause wear and blockage of the conveyor belt, reducing work efficiency. More importantly, as the use time increases, solid waste will continue to accumulate on the conveyor belt surface, forming a thick layer of sediment, making cleaning work extremely difficult and increasing maintenance costs and time.

[0004] Solid waste rolling and ground pollution: Considering the fluidity of coal powder, traditional feeding devices are usually designed with a certain slope so that the coal powder can slide smoothly into the combustion chamber. However, this design also brings new problems: during the transmission process, some solid waste materials (especially coal slag with larger particles) are easily affected by the slope and fall from the surface of the conveyor belt and fall to the ground or other areas. This not only causes environmental pollution, but also may pose a safety hazard to surrounding equipment and personnel. At the same time, it is also quite troublesome to collect the rolled solid waste materials, which increases the additional cleaning workload and cost.

[0005] In view of the above problems, the application of traditional feeding devices in coal-fired power production is greatly limited. Therefore, it is necessary to improve and innovate the existing feeding devices to improve their working efficiency, reduce maintenance costs, reduce environmental pollution, and ensure production safety.

[0031] In order to better understand the purpose, structure and function of the present invention, the coupled co-firing solid waste feeding device for coal power plants of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-7 As shown, a coupled solid waste feeding device for coal-fired power plants of the present invention comprises a device body 1 and a support frame 20, wherein the two ends of the device body 1 are respectively a first end and a second end, the height of the first end is higher than the second end, and the device body 1 is arranged on the support frame 20. A belt is arranged on the device body 1 for feeding. Baffles 22 are arranged on both sides of the device body 1 to prevent materials from falling.

[0033] The first end of the device body 1 is provided with a transverse plate 6, which is arranged on the lower side of the first end to prevent the material from being loaded. The length of the transverse plate 6 is equal to the length of the device body 1. The inner surface of the transverse plate 6 (facing the end face of the device body 1) is provided with several layers of brushes 5, preferably 2-3 layers.

[0034] The two sides of the horizontal plate 6 are respectively fixedly connected to the square plate 14, the square plate 14 is arranged vertically, and a through groove is opened in the middle position. The two sides of the baffle 22 are fixedly connected to the plug plate 19, the plug plate 19 is inserted into the square plate 14, and the plug plate 19 is rotatably connected inside. The side of the plug plate 19 is fixedly connected to the rotating plate 18, and a fixed block 13 is provided on the surface of the square plate 14. When the rotating plate 18 rotates, it can be inserted into the two fixed plates 13, so that the square plate 14 and the plug plate 19 are connected, and then the device body 1 and the horizontal plate 6 are connected; by adding a horizontal plate 6 on the side of the device body 1, a brush 5 is added on the surface of the horizontal plate 6, and the square plate 1 is installed on the side of the horizontal plate 6 4. A plug plate 19 is installed on the side of the device body 1, and a shaft 17 is added inside the plug plate 19. A rotating plate 18 is installed on the side of the shaft 17. A fixed block 13 is added on the surface of the square plate 14. Before loading, the horizontal plate 6 is first installed on the side of the device body 1, and the square plate 14 is inserted outside the plug plate 19. The shaft 17 is rotated, and the rotating plate 18 is rotated by rotating the shaft 17, and the rotating plate 18 is turned into the fixed block 13. At this time, the horizontal plate 6 and the brush 5 can be fixed. When there is a fixed bond on the surface of the feeding device, it can be directly brushed off by the brush 5, so that it falls inside the combustion chamber, making it more convenient to clean.

[0035] The second end of the device body 1 is rotatably connected to the collection frame 2. The upper end of the side plate of the collection frame 2 facing the device body 1 is provided with a connecting plate 4. The connecting plate 4 can contact the lower end of the device body 1 to prevent the conveyed materials from falling. The side plate of the collection frame 2 facing the device body 1 is fixedly connected to the outside of two pairs of first mounting plates 7.

After the internal threaded tube 8 is inserted into the first mounting plate 7 and the second mounting plate 10, the threaded rod 11 is screwed into the internal threaded tube 8 to fix the collecting frame 2. When solid waste rolls down from the surface of the feeding device, it can directly roll into the collecting frame 2, making it more convenient to use.

[0036] In some embodiments of the present invention, see Figure 7 , a slot 21 is provided on the surface of the fixed block 13. In the two slots 21 on both sides of the same square plate 14, one opening faces the inside and the bottom, and the other opening faces the inside and the top, so that when the rotating plate 18 is arranged vertically, it can be separated from the through slot provided in the square plate 14. When the rotating plate 18 rotates, it can be inserted into the corresponding slot 21. Because the slot with the opening facing downward is sealed at the upper end, it can prevent the rotating plate from rotating out. The slot with the opening facing upward is sealed at the lower end to prevent the rotating plate from further rotating and disengaging. . A card slot 15 is provided inside each slot 21. A card block 16 is fixedly connected to the surface of the rotating plate 18. The card block 16 is embedded inside the card slot 15. By installing the slot 21 on the surface of the fixed block 13, and providing the card slot 15 inside the slot 21, a card block 16 is fixed on the surface of the rotating plate 18. The rotating plate 18 is rotated, the rotating plate 18 is inserted into the slot 21, and the card block 16 is embedded inside the card slot 15. At this time, the horizontal plate 6 can be fixed to the side of the device body 1. The block 16 cooperates with the slot 15 so that the rotating plate can be limited in position in the slot, and the slot and the rotating plate are further locked to prevent the rotating plate from falling off from the slot.

[0037] In some embodiments of the present invention, a baffle 9 is fixedly provided at the inner end of the internal threaded barrel 8, and each inner end of the internal threaded barrel 8 is provided with a baffle 9, which is larger than the outer diameter of the internal threaded barrel 8, and the outer end of the threaded rod 11 is fixedly connected to a turntable 12. By installing a turntable 12 at one end of the threaded rod 11, the threaded rod 11 can be screwed by rotating the turntable 12, and the threaded rod 11 is screwed into the internal threaded barrel 8 from the outside of the internal threaded barrel 8 to fix a set of connecting parts. By installing a baffle 9 on the side of the internal threaded barrel 8, combined with the screw 11, the internal threaded barrel 8 can be prevented from slipping out from the first mounting plate 7 and the second mounting plate 10.

[0038] A pulley 3 is provided at the bottom of the collecting frame 2 , and the pulleys 3 are symmetrically distributed. By installing the pulley 3 at the bottom of the collecting frame 2 , the collecting frame 2 can be conveniently moved by the pulley 3 .

[0039] The working principle of the coupled solid waste feeding device for coal power plants is as follows: when the feeding device is used, the horizontal plate 6 is first installed on the side of the device body 1, the square plate 14 is inserted on the outside of the plug plate 19, the shaft 17 is rotated, and the rotating plate 18 is rotated by rotating the shaft 17, and the rotating plate 18 is inserted into the slot 21, and the card block 16 is embedded in the card slot 15. At this time, the horizontal plate 6 can be fixed on the side of the device body 1. At this time, the horizontal plate 6 and the brush 5 can be fixed. When there is a fixed bond on the surface of the feeding device, it can be directly brushed off by the brush 5, so that It falls inside the combustion chamber, making it easier to clean. The collecting frame 2 is mounted on the side of the feeding device, and the second mounting plate 10 is inserted between the two first mounting plates 7. The internal threaded tube 8 is inserted into the first mounting plate 7 and the second mounting plate 10. The turntable 12 is rotated to screw the threaded rod 11 into the internal threaded tube 8 to fix the collecting frame 2. When solid waste rolls down from the surface of the feeding device, it can directly roll into the collecting frame 2, making it easier to use. At this time, the feeding device can be started and the solid waste can be directly placed on the surface of the feeding device.

[0040] The device of the present invention effectively solves the problem of accumulation of solid waste due to adhesion during the loading process by adding a horizontal plate and a brush design on the side of the device body. The presence of the brush allows the solid waste residue to be easily brushed off and directly fall into the combustion chamber, which not only reduces the frequency of manual cleaning, but also avoids equipment downtime caused by cleaning, thereby improving the overall operating efficiency of the coal-fired power plant. The coordinated design of the shaft, the rotating plate and the fixed block enables the rapid installation and disassembly of the horizontal plate and the brush device. This design not only simplifies the installation process and reduces maintenance costs, but also makes the operation easier and faster when the brush needs to be replaced or cleaned, thereby improving the maintainability and flexibility of the equipment. The additional collection frame and its supporting mounting structure (such as the connecting plate, the first mounting plate, the second mounting plate, the internal threaded barrel and the threaded rod) constitute an efficient and convenient solid waste collection system. The system can effectively collect solid waste that rolls off the surface of the device, avoiding material waste and environmental pollution, In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
