Description

Technical Field

[0001] This utility model relates to the field of power plant fuel supply technology, and in particular to a fuel supply device. Background Technology

[0002] A power plant, often simply called a power plant, is a factory that converts various primary energy sources (such as hydropower, coal, oil, natural gas, nuclear power, wind power, and solar power) into electrical energy. Based on the type of energy used, power plants can be divided into several types, such as thermal power plants, hydropower plants, nuclear power plants, wind power plants, and solar power plants. Thermal power plants are the primary energy source, mainly generating electricity by burning coal.

[0003] Existing small-scale thermal power plants mainly use coal combustion for power generation. In actual operation, coal is fed and burned by a coal conveying mechanism. However, when the conveying mechanism is under maintenance or the equipment fails, manual coal feeding is required to maintain the operation of the power generation equipment and provide the necessary energy.

[0004] Based on the aforementioned technologies, the applicant believes that during equipment maintenance or malfunction, manual coal feeding cannot achieve uniform feeding, and prolonged coal feeding results in a huge workload for workers, which is not conducive to providing stable energy to power generation equipment. In response to the above problems, we have introduced a fuel supply device. Utility Model Content

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] The fuel supply device disclosed in this utility model is mainly used in power plant fuel supply scenarios.

[0027] Reference Figure 1 - Figure 4 A fuel supply device includes a fixed base 1, with support rods 2 symmetrically fixedly connected to both sides of the top of the fixed base 1. A combustion boiler 3 is fixedly connected to the top of the fixed base 1. A support plate 4 is fixedly connected to the top of the support rods 2. A coal storage box 5 is fixedly connected to one side of the top of the support plate 4. A coal outlet chute 6 is provided on the outer side of the coal storage box 5 and above the combustion boiler 3. An intermittent coal feeding mechanism is provided on the top of the support plate 4. The intermittent coal feeding mechanism includes a coal feeding component and a power component, which cooperate with each other. The coal feeding component includes a rotating shaft 71. A rotating shaft 71 is rotatably connected inside the coal storage box 5. One end of the rotating shaft 71 extends to the outside of the coal storage box 5 and is fixedly connected to a grooved wheel 72. A feeding rack 73 is fixedly connected to the outside of the rotating shaft 71. A connecting shaft 74 is rotatably connected inside the coal storage box 5 and above the feeding rack 73. One end of the connecting shaft 74 extends to the outside of the coal storage box 5 and is fixedly connected to a rotating disk 75. A stabilizing disk 76 is fixedly connected to the outside of the rotating disk 75. A sliding column 77 is fixedly connected to the outside of the rotating disk 75. The sliding column 77 cooperates with the sliding groove opened inside the grooved wheel 72. The power assembly includes a motor 78, which is fixedly connected to the top of the coal storage box 5. A first pulley 79 is fixedly connected to the output end of the motor 78, and a second pulley 710 is fixedly connected to the other end of the connecting shaft 74. The first pulley 79 and the second pulley 710 are connected by a belt drive.

[0028] In this embodiment: because the bottom of the inner wall of the coal storage box 5 is inclined, the coal will roll to the coal discharge chute 6. The output end of the motor 78 rotates, driving the first pulley 79 to rotate, the second pulley 710 to rotate, driving the connecting shaft 74 to rotate, the connecting shaft 74 to rotate, driving the rotating disk 75 to rotate, the rotating disk 75 to rotate, driving the sliding column 77 to rotate, the sliding column 77 to slide in the groove of the groove wheel 72, causing the groove wheel 72 to rotate intermittently, the groove wheel 72 to rotate, driving the rotating shaft 71 to rotate, the rotating shaft 71 to rotate, and the feeding rack 73 to rotate. The grooves on the outer side of the feeding rack 73, which are arranged in a circumferential array, begin to intermittently transport the coal through the feeding chute 10 to the interior of the combustion boiler 3. Through the intermittent coal feeding mechanism, manual coal feeding can be replaced, ensuring that the coal is normally and evenly transported to the interior of the combustion boiler 3 when the equipment is under maintenance or damaged, providing a continuous and stable energy source for the power generation equipment. The structure is simple and highly practical.

[0029] In the above technical solution, considering that manual coal feeding cannot achieve uniform feeding during equipment maintenance or malfunction, and that prolonged coal feeding results in a huge workload for workers, which is not conducive to a stable supply of energy to the power generation equipment, the specific operation is as follows: Reference Figure 1 - Figure 4 In a preferred embodiment, a feeding trough 8 is provided on the top of the coal storage box 5, and a feeding hopper 9 is fixedly connected to the top of the coal storage box 5 and above the feeding trough 8. A receiving hopper 11 is fixedly connected to one side of the top of the combustion boiler 3, and a discharge trough 10 is provided inside the support plate 4 and above the receiving hopper 11. Diagonal braces 12 are symmetrically fixedly connected to the outer side of the support rod 2, and the other end of the diagonal braces 12 is fixedly connected to the bottom of the support plate 4. A controller 13 is fixedly connected to the outer side of the coal storage box 5, and a motor 78 is electrically connected to the controller 13.

[0030] In this embodiment, the feeding trough 8 and feeding hopper 9 facilitate the addition of coal to the coal storage box 5 by the staff. The receiving hopper 11 prevents coal from falling out. The inclined support rod 12 makes the support plate 4 more stable. The controller 13 makes it easy for the staff to control the opening and closing of the motor 78, making the operation simpler.

[0031] Working principle: When the coal feeding equipment is under maintenance or malfunctions, the staff first adds coal into the coal storage box 5, and then starts the motor 78. Since the bottom of the inner wall of the coal storage box 5 is inclined, the coal will roll to the coal discharge chute 6. The output end of the motor 78 rotates, driving the first pulley 79 to rotate. The second pulley 710 rotates, driving the connecting shaft 74 to rotate. The connecting shaft 74 rotates, driving the rotating disk 75 to rotate. The rotating disk 75 rotates, driving the sliding column 77 to rotate. The sliding column 77 slides in the groove of the groove wheel 72, causing the groove wheel 72 to rotate intermittently. The rotation of the groove wheel 72 drives the rotating shaft 71 to rotate. The rotation of the rotating shaft 71 drives the feeding rack 73 to rotate. The grooves arranged in a circular array on the outer side of the feeding rack 73 begin to intermittently transport the coal through the feeding chute 10 to the interior of the combustion boiler 3 for combustion.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
