Description

Technical Field

[0001] This utility model belongs to the field of thermal power plant boiler technology, and in particular relates to a device for unblocking the feed inlet of a thermal power plant boiler. Background Technology

[0002] A thermal power plant boiler is a device that uses fuels such as coal, oil, or gas to burn and heat water into high-temperature, high-pressure steam, which drives a turbine to generate electricity. It is the core device in a thermal power plant, responsible for converting energy into heat energy, then into steam, which drives the turbine to operate, and finally into electricity.

[0003] For example, Chinese patent CN220152775U discloses a coal-fired boiler, including a furnace body with a coal inlet and a flue pipe. The coal inlet is connected to a coal feed pipe, and the coal feed pipe is connected to a cooperating feeding assembly and a blowing assembly. The blowing assembly includes a blower, the blower's outlet connected to one end of the coal feed pipe, and the blower's inlet connected to an air inlet pipe. A serpentine coil is connected to the air inlet end of the air inlet pipe, and the serpentine coil is wound around the flue pipe. This invention, by setting up a cooperating feeding assembly and blowing assembly, reduces labor costs, improves safety, and preheats the coal and air entering the furnace, resulting in more complete combustion and improved combustion efficiency.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, when the user adds pulverized coal into the boiler through the feed pipe, some incompletely crushed coal lumps may be present. When a large amount of pulverized coal and incompletely crushed coal lumps enter the feed pipe, it may clog the pipe, preventing the fuel from burning smoothly and potentially reducing the boiler's thermal efficiency. Therefore, we propose a clogging device for the feed inlet of a thermal power plant boiler. Utility Model Content

[0006] The purpose of this invention is to provide a device for unblocking the feed inlet of a thermal power plant boiler, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a device for unblocking the feed inlet of a thermal power plant boiler, comprising a boiler and a feed pipe, and further comprising:

[0008] A first fixed plate is fixedly connected to the inner wall of the feed pipe. A sliding rod is slidably connected inside the first fixed plate, and two unblocking blocks are fixedly connected to the periphery of the sliding rod.

[0009] A rotating rod is rotatably connected to the inner wall of the feed pipe. One end of the rotating rod is fixedly connected to a first transmission rod, and one side of the first transmission rod is rotatably connected to a second transmission rod that rotates with the top of the slide rod.

[0010] A rotating groove is formed on the inner wall of the feed pipe, and two unclogging rollers are rotatably connected inside the rotating groove;

[0011] The second fixing plate is fixedly connected to one side of the feed pipe. A motor is fixedly connected to the second fixing plate, and the output shaft of the motor passes through the feed pipe and extends into the rotating groove and is fixed to one end of one of the unblocking rollers.

[0012] The first transmission assembly is located on the feed pipe and is used to drive the rotating rod to rotate;

[0013] The second transmission assembly is located inside the feed pipe and is used to drive another unclogging roller to rotate.

[0014] Based on the above structure, the first fixed plate, sliding rod, and unblocking blocks ensure that the sliding rod can drive the two unblocking blocks to move up and down within the first fixed plate. The rotating rod, first transmission rod, and second transmission rod ensure that when the rotating rod rotates, it drives the first transmission rod to rotate, which in turn drives the sliding rod to reciprocate up and down via the second transmission rod. This causes the sliding rod to push a large amount of fuel down the two unblocking blocks. The rotating groove and unblocking rollers ensure that the two unblocking rollers can rotate within the rotating groove. The motor ensures that its output shaft can drive one of the unblocking rollers to rotate. The first transmission assembly ensures that when the motor starts, it can drive the rotating rod to rotate via the first transmission assembly. The second transmission assembly ensures that when the motor starts, it can drive the other unblocking roller to rotate in the opposite direction via the second transmission assembly. When the two unblocking rollers rotate in opposite directions, they can push a large amount of fuel into the boiler.

[0015] In the above technical solution, the first transmission component further includes:

[0016] The first sprocket is fixedly connected to the output shaft of the motor;

[0017] The second sprocket is rotatably connected to the feed pipe, and one end of the second sprocket passes through the feed pipe and extends into the feed pipe and is fixed to the other end of the rotating rod. The second sprocket and the first sprocket are meshed with a first chain.

[0018] In this technical solution, it is ensured that the two unclogging rollers can rotate in opposite directions.

[0019] In the above technical solution, one end of the second sprocket is rotatably connected to the feed pipe.

[0020] In this technical solution, it is ensured that one end of the second sprocket can rotate normally inside the feed pipe.

[0021] In the above technical solution, the second transmission component further includes:

[0022] The gear groove is formed inside the feed pipe. A first gear and a second gear are rotatably connected inside the gear groove, and the first gear and the second gear mesh with each other. One end of the first gear passes through the inner wall of the gear groove and extends into the rotating groove to be fixed to one end of another unclogging roller.

[0023] The movable groove is located inside the feed pipe and is connected to the gear groove. A third sprocket and a fourth sprocket are rotatably connected inside the movable groove, and the fourth sprocket is fixedly connected to the output shaft of the motor. One end of the third sprocket passes through the inner wall of the movable groove and extends into the gear groove to be fixed to the second gear. A second chain meshes between the third sprocket and the fourth sprocket.

[0024] In this technical solution, it is ensured that when the first transmission rod rotates, the first transmission rod will drive the slide rod to move up and down reciprocally through the second transmission rod.

[0025] In the above technical solution, one end of the first gear is rotatably connected to the rotating groove.

[0026] In this technical solution, it is ensured that one end of the first gear can rotate normally within the rotating groove.

[0027] In the above technical solution, one end of the third sprocket is rotatably connected to the gear groove.

[0028] In this technical solution, it is ensured that one end of the third sprocket can rotate normally within the gear groove.

[0029] In the above technical solution, the output shaft of the motor is rotatably connected to the feed pipe.

[0030] In this technical solution, it is ensured that the output shaft of the motor can rotate normally inside the feed tube.

[0031] The beneficial effects of this utility model are:

[0032] The boiler feed inlet unblocking device in this thermal power plant, through the setting of a first fixed plate, a sliding rod, and unblocking blocks, ensures that the sliding rod can drive two unblocking blocks to move up and down within the first fixed plate. Through the setting of a rotating rod, a first transmission rod, and a second transmission rod, it ensures that when the rotating rod rotates, it drives the first transmission rod to rotate, causing the first transmission rod to drive the sliding rod to reciprocate up and down via the second transmission rod. This causes the sliding rod to drive the two unblocking blocks to reciprocate and press down a large amount of fuel. Through the setting of a rotating groove and unblocking rollers, it ensures that the two unblocking rollers can rotate within the rotating groove. Through the setting of a motor, it ensures that the output shaft of the motor can drive one of the unblocking blocks. The two unclogging rollers rotate. Through the first transmission component, it is ensured that when the motor starts, the motor can drive the rotating rod to rotate through the first transmission component. Through the second transmission component, it is ensured that when the motor starts, the motor will drive the other unclogging roller to rotate in the opposite direction through the second transmission component. When the two unclogging rollers rotate in opposite directions, they can push a large amount of fuel into the boiler. This solves the problem that when a large amount of coal powder and incompletely crushed coal lumps enter the feed pipe, it may block the coal pipe, preventing the fuel from burning smoothly and potentially reducing the boiler's thermal efficiency.
