Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a material conveying equipment and method for a power system. Background Art

[0002] The power system is an electric energy production and consumption system consisting of power plants, power transmission and transformation lines, power distribution stations and power consumption. Its function is to convert primary energy from nature into electric energy through power generation devices, and then supply the electric energy to various users through transmission, transformation and distribution. During the operation of the power system, the selection and application of materials are directly related to energy utilization efficiency, environmental protection and the overall operation efficiency of the system. Especially in the context of coal as the main energy source, the combustion efficiency of coal and its impact on the environment have become the focus of the power system.

[0003] However, due to the large volume of coal blocks, the contact area between oxygen and coal is limited during the combustion process, and the combustion reaction is not complete. When the coal is not burned completely, the actual heat generated is far lower than the heat generated by complete combustion in theory, which leads to a huge waste of energy. In addition, due to the reduced combustion efficiency, more coal is needed to generate the same amount of heat, thereby increasing production costs. When the coal is not burned completely, a large amount of pollutants such as carbon monoxide, sulfur dioxide, and nitrogen oxides will be generated, causing serious pollution to the environment. In addition, unstable combustion may cause the boiler to shut down or operate unstablely, which in turn affects the stability and reliability of the entire power system. Summary of the invention

[0020] A material conveying method for an electric power system, applied to the above-mentioned material conveying equipment for an electric power system, comprises the following steps: S1: When in use, the moving motor is started. Under the transmission action of the moving motor and the belt, the two threaded rods rotate. When the two threaded rods rotate, the two moving plates are driven to move up and down along the direction of the threaded rods, thereby driving the two mounting plates to rise or fall.

After the large pieces of coal enter the crushing box, they are crushed into small pieces of coal under the action of the crushing roller, thereby improving the combustion efficiency. S3: Small pieces of coal are transported to the inside of the storage box as the conveyor belt and the vertical plate rotate. At this time, the small particles of coal stuck to the top of the conveyor belt fall into the inside of the storage bucket as the conveyor belt continues to run. The conveying motor is started, and the conveying motor drives the auger to rotate, and then the auger transports the fine coal inside the conveying pipe, and finally enters the inside of the storage box.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are: Through the coordinated use of the feed hopper, fixed frame, servo motor, eccentric wheel, support frame, crushing box, drive motor, crushing roller, screen plate, rotating rod, base, hinge spring and contact wheel, it is convenient to separate coal blocks of different sizes and crush large-volume coal blocks at the same time, thereby improving the combustion efficiency of the coal blocks, and then improving the coal conversion efficiency and increasing the power generation.

[0022] Through the coordinated use of threaded rods, movable plates, mounting plates and folding plates, the falling coal particles can be shielded to prevent the coal particles from splashing when falling, thereby preventing the external working environment from being polluted.

[0023] Through the coordinated use of the receiving bucket, conveying pipe, conveying motor, auger, positioning frame and storage box, it is convenient to collect the coal particles stuck on the top of the conveyor belt, thereby preventing the coal particles from falling to the outside when the conveyor belt is running, thereby preventing the external environment from being polluted.

[0034] A material conveying method for an electric power system, applied to the above-mentioned material conveying equipment for an electric power system, comprises the following steps: S1: When in use, the moving motor 306 is started. Under the transmission action of the moving motor 306 and the belt 307, the two threaded rods 302 rotate. When the two threaded rods 302 rotate, the two moving plates 303 are driven to move up and down along the direction of the threaded rods 302, thereby driving the two mounting plates 304 to rise or fall.

Since the eccentric wheel 205 is an irregular circle, the eccentric wheel 205 will resist the resistance wheel 214 when rotating, so that the top of the sieve plate 210 is separated from the bottom of the feed hopper 202, and the two Under the action of the hinge spring 213, the screen plate 210 and the feed hopper 202 will continuously separate and collide with each other. As the screen plate 210 shakes, the coal inside the feed hopper 202 will roll along the top of the screen plate 210 to the inside of the crushing box 207.

After the large pieces of coal enter the crushing box 207, they will be crushed into small pieces of coal under the action of the crushing roller 209, thereby improving the combustion efficiency and starting the The two threaded rods 302 rotate under the driving action of the moving motor 306 and the belt 307. When the two threaded rods 302 rotate, the two moving plates 303 are driven to move up and down along the direction of the threaded rods 302, thereby driving the two mounting plates 304 to rise or fall. When the two mounting plates 304 rise and fall, the two folding plates 305 are driven to fold or extend. When the two folding plates 305 are extended, the conveyor belt 404 can be blocked to prevent the conveyor from being damaged. Dust on the top of the conveyor belt 404 splashes, and small pieces of coal are transported to the inside of the storage box 412 as the conveyor belt 404 and the vertical plate 405 rotate. At this time, the small particles of coal stuck to the top of the conveyor belt 404 fall into the inside of the receiving bucket 406 as the conveyor belt 404 continues to operate, and the conveying motor 408 is started, and the conveying motor 408 drives the auger 409 to rotate, and then the auger 409 transports the fine coal inside the conveying pipe 407, and finally enters the inside of the storage box 412.

8. The material conveying equipment for a power system according to claim 7, characterized in that: The top of the workbench (1) is fixedly connected to a storage box (412), the outer side wall of the storage box (412) is fixedly connected to a positioning frame (410), and the side of the positioning frame (410) away from the storage box (412) is connected to the auger (409).

9. A material conveying method for an electric power system, applied to a material conveying device for an electric power system as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: When in use, the moving motor (306) is started. Under the driving action of the moving motor (306) and the belt (307), the two threaded rods (302) rotate. When the two threaded rods (302) rotate, the two moving plates (303) are driven to move up and down along the direction of the threaded rods (302), thereby driving the two mounting plates (304) to rise or fall. When the two mounting plates (304) rise and fall, the two folding plates (305) are driven to fold or extend. When the two folding plates (305) are extended, the conveyor belt (404) can be shielded to prevent dust from splashing on the top of the conveyor belt (404); S2: Lump coal is put into the feed hopper (202), and the servo motor (204) is started. The servo motor (204) drives the eccentric wheel (205) to rotate. When the eccentric wheel (205) rotates, it will interfere with the top of the interference wheel (214). Since the eccentric wheel (205) is an irregular circle, the eccentric wheel (205) will interfere with the interference wheel (214) when rotating, so that the top of the screen plate (210) is separated from the bottom of the feed hopper (202), and the two hinge springs (213) are connected. Under the action of the conveyor belt (404), the sieve plate (210) and the feed hopper (202) will continuously separate and collide with each other. As the sieve plate (210) shakes, the coal inside the feed hopper (202) will roll along the top of the sieve plate (210) to the inside of the crushing box (207). During the rolling process, fine coal particles will fall along the holes opened on the top of the sieve plate (210) to the top of the conveyor belt (404). After large pieces of coal enter the crushing box (207), they are crushed into small pieces of coal under the action of the crushing rollers (209), thereby improving the combustion efficiency. S3: Small pieces of coal are transported to the interior of the storage box (412) as the conveyor belt (404) and the vertical plate (405) rotate. At this time, the small particles of coal adhering to the top of the conveyor belt (404) fall into the interior of the storage bucket (406) as the conveyor belt (404) continues to operate, and the conveying motor (408) is started. The conveying motor (408) drives the auger (409) to rotate, and then the auger (409) transports the fine coal inside the conveying pipe (407) and finally enters the interior of the storage box (412).
