Description

Technical Field

[0001] This utility model relates to the field of coal-fired power generation, specifically a coal mill stone and coal discharge device. Background Technology

[0002] Coal-fired power generation refers to the process of using coal as fuel to generate heat energy through combustion, which is then converted into electrical energy. It is also a traditional power generation method widely used globally. Coal dust is a solid waste generated during the operation of coal mills in coal-fired power plants. It mainly consists of impurities in coal that are difficult to grind and some incompletely burned coal particles. Coal dust discharge devices are devices used in coal-fired power plants to treat non-combustible residues generated after boiler combustion.

[0003] In existing technologies, existing stone and coal discharge devices cause pollution because the stone and coal contain light coal dust, which is scattered into the air when the stone and coal are dumped. Furthermore, some lighter stone and coal particles may remain in the device during dumping, increasing cleaning difficulty. The existing devices also make it difficult to expel the stone and coal particles from the device, reducing the convenience of using them. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in removing loose coal dust during dumping of coal and inconvenience in pushing out coal particles from the device, this utility model proposes a coal mill coal discharge device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The coal mill stone and coal discharge device of this utility model includes a fixed plate; a dust removal component is fixedly connected to the middle of the top of the fixed plate; a collection plate is rotatably connected to the inner surface of the fixed plate; a discharge port is opened at one end of the collection plate; a closing door for opening and closing is provided on the side of the surface of the collection plate near the discharge port; and a discharge component is rotatably connected to the surface of the collection plate.

[0006] The dust removal assembly includes a dust removal fan fixedly connected to the middle of the top of the fixed plate, a suction head being connected through one side of the dust removal fan, a connecting pipe being connected through one end of the dust removal fan, and a filter cartridge being connected through one end of the connecting pipe.

[0007] The discharge assembly includes a threaded rod fixedly connected to the surface of the collecting plate. One end of the threaded rod is fixedly connected to a transmission rod, and one end of the transmission rod is splinedly connected to the output end of a servo motor. The surface of the threaded rod is threadedly connected to a discharge plate, and the two sides of the discharge plate are slidably connected to collecting plates.

[0008] Preferably, fixing plates A are fixedly connected to both sides of the fixing plate, an electric push rod is rotatably connected to the bottom of the fixing plate A, fixing plate B is rotatably connected to the bottom of the electric push rod, and a collecting plate is fixedly connected to one side of the fixing plate B.

[0009] Preferably, a pad is fixedly connected to the bottom of the suction head, and a fixing plate is fixedly connected to the bottom of the pad.

[0010] Preferably, an inlet cylinder is fixedly connected to the top edge of the fixed plate, and a diverter block is fixedly connected to the inner surface of the inlet cylinder.

[0011] Preferably, rotating blocks are fixedly connected to both sides of the collecting plate, and fixed plates are rotatably connected to the surface of the rotating blocks.

[0012] Preferably, a motor housing is fixedly connected to the surface of the servo motor, and a collecting plate is fixedly connected to one side of the motor housing.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the structural design of the dust removal component, allows the dust removal fan to be connected to a power source when the stone coal is being dumped using this emission device. The dust generated at the dumping location is sucked in through the suction head and thrown towards the outer edge of the impeller under centrifugal force, forming a high-pressure airflow. Finally, the airflow flows from the connecting pipe to the filter cartridge, and the dust in the airflow is filtered out and discharged. This enables the stone coal emission device to remove the loosened dust when dumping stone coal, thus avoiding pollution.

[0015] 2. Through the structural design of the discharge component, when using the discharge device to pour stones and coal, the servo motor is connected to the power supply and energized, causing the transmission rod to drive the threaded rod to rotate. Since the two sides of the discharge plate are slidably connected to the collection plate, the threaded rod can push the discharge plate along the threaded rod to push out the stones and coal when rotating, thus improving the convenience of using the stone and coal discharge device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a coal mill stone and coal discharge device includes a fixed plate 1; a dust removal component 2 is fixedly connected to the middle of the top of the fixed plate 1, a collection plate 3 is rotatably connected to the inner surface of the fixed plate 1, a discharge port is opened at one end of the collection plate 3, a closing door 4 for opening and closing is provided on the side of the surface of the collection plate 3 near the discharge port, and a discharge component 5 is rotatably connected to the surface of the collection plate 3.

[0024] The dust removal assembly 2 includes a dust removal fan 201 fixedly connected to the middle of the top of the fixed plate 1. A suction head 202 is connected through one side of the dust removal fan 201. A connecting pipe 203 is connected through one end of the dust removal fan 201. A filter cartridge 204 is connected through one end of the connecting pipe 203.

[0025] The discharge assembly 5 includes a threaded rod 501 fixedly connected to the surface of the collection plate 3. One end of the threaded rod 501 is fixedly connected to a transmission rod 502. One end of the transmission rod 502 is splinedly connected to the output end of the servo motor 503. The surface of the threaded rod 501 is threadedly connected to a discharge plate 504. The two sides of the discharge plate 504 are slidably connected to the collection plate 3.

[0026] During operation, thanks to the structure of the dust removal component 2, when using this emission device to pour stones and coal, the dust removal fan 201 is connected to the power supply and energized. The pulverized coal generated at the pouring location is sucked in by the suction head 202 and thrown towards the outer edge of the impeller under centrifugal force, forming a high-pressure airflow. Finally, the airflow flows from the connecting pipe 203 to the filter cartridge 204, and the pulverized coal in the airflow is filtered out and discharged. This allows the stone and coal emission device to remove the scattered pulverized coal when pouring stones and coal, avoiding pollution. Thanks to the structure of the discharge component 5, when using this emission device to pour stones and coal, the servo motor 503 is connected to the power supply and energized, causing the transmission rod 502 to drive the threaded rod 501 to rotate. Since the two sides of the discharge plate 504 are slidably connected to the collection plate 3, the threaded rod 501 can push the discharge plate 504 along the threaded rod 501 to push out the stones and coal when rotating. This allows the stone and coal emission device to push out the stones and coal particles in the device, improving the convenience of using the stone and coal emission device.

[0027] Furthermore, A fixing plates 6 are fixedly connected to both sides of the fixing plate 1, an electric push rod 7 is rotatably connected to the bottom of the A fixing plate 6, a B fixing plate 8 is rotatably connected to the bottom of the electric push rod 7, and a collecting plate 3 is fixedly connected to one side of the B fixing plate 8.

[0028] During operation, by setting the electric push rod 7, before using the discharge component 5, the closed door 4 is opened, the electric push rod 7 is powered on, and the electric push rod 7 pushes the collection plate 3 to tilt, and under the action of gravity, the larger stones and coal are poured out, reducing the burden of using the discharge component 5.

[0029] Furthermore, a pad 9 is fixedly connected to the bottom of the suction head 202, and a fixing plate 1 is fixedly connected to the bottom of the pad 9;

[0030] During operation, the pad 9 allows the suction head 202 to be connected to the dust removal fan 201 through a straight pipe, preventing coal ash from accumulating inside the pipe.

[0031] Furthermore, an inlet cylinder 10 is fixedly connected to the top edge of the fixed plate 1, and a diverter block 11 is fixedly connected to the inner surface of the inlet cylinder 10;

[0032] During operation, the diversion block 11 is used to divert the stones and coal to both sides when they pass through the inlet cylinder 10, preventing the stones and coal from hitting the threaded rod 501 and improving the service life of the equipment.

[0033] Furthermore, rotating blocks 12 are fixedly connected to both sides of the collecting plate 3, and fixed plates 1 are rotatably connected to the surface of the rotating blocks 12;

[0034] During operation, by setting the rotating block 12, when the electric push rod 7 is extended, the collecting plate 3 can rotate and tilt around the center of the rotating block 12 as the axis of rotation.

[0035] Furthermore, a motor housing 13 is fixedly connected to the surface of the servo motor 503, and a collection plate 3 is fixedly connected to one side of the motor housing 13.

[0036] During operation, the servo motor 503 can be protected and supported by the motor box 13.

[0037] Working principle: Before using the discharge device to dump the stones and coal, open the closed door 4 and turn on the electric push rod 7 to push the collection plate 3 to tilt. Under the action of gravity, the larger stones and coal are dumped out. Then, connect the servo motor 503 to the power supply and turn on the power supply, so that the transmission rod 502 drives the threaded rod 501 to rotate. Since the two sides of the discharge plate 504 are slidably connected to the collection plate 3, the threaded rod 501 can push the discharge plate 504 along the threaded rod 501 to push out the lighter stones and coal particles when rotating. During the process of dumping the stones and coal using the discharge device, connect the dust removal fan 201 to the power supply and turn on the power supply. After the coal dust generated at the dumping position is sucked in by the suction head 202, it is thrown to the outer edge of the impeller under the action of centrifugal force and forms a high-pressure airflow. Finally, the airflow flows from the connecting pipe 203 to the filter cartridge 204, and the coal dust in the airflow is filtered out and discharged.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
