Description

Technical Field

[0001] This application relates to the field of coal feeding, and more particularly, to a feeding device suitable for thermal power generation. Background Art

[0002] Coal is a solid combustible mineral formed by the complex biochemical and physicochemical changes of ancient plants buried underground. Coal is hailed as black gold and the food of industry. It has been one of the main energy sources used by the human world since the 18th century. Since the 21st century, although the value of coal is much lower than before, after all, coal is still one of the indispensable energy sources for our human production and life in the current and future for a long time. The supply of coal is also related to the stability of the development of China's industry and even all aspects of the whole society. The supply security of coal is also the most important part of China's energy security. There are many thermal power plants in China, and most of these thermal power plants use coal as fuel. However, coal is not directly fed into the furnace for combustion, but needs to be ground into powder first. In this way, the contact area with oxygen is larger during the combustion process, and the combustion is more intense. Therefore, grinding coal into powder before combustion is to improve the combustion rate of coal and avoid waste of resources.

[0003] The patent document with the publication number CN113188144B discloses a feeding device suitable for thermal power generation. The invention discloses a feeding device suitable for thermal power generation, including a device main body, including a feeding pipeline, a secondary treatment component, and a collecting and feeding pipeline; the feeding pipeline is arranged above, the secondary treatment component is connected to the bottom of the feeding pipeline, and the collecting and feeding pipeline is connected to the bottom of the secondary treatment component.

[0004] In the above application document, coal is crushed to facilitate feeding. However, it has the problem of being inconvenient to fully crush coal. It crushes coal by applying pressure unidirectionally downward, and the coal may be difficult to be fully crushed. It is not convenient to grind coal left and right during downward pressure application to enhance the crushing effect, and it is not convenient to make the coal be fully pulverized.

A channel is provided in the rolling seat 404 for the communication between the first hose 906 and the second hose 903.

[0030] When the above equipment is in specific use, when the push plate 607 moves left and right continuously, it will also drive the fifth hydraulic rod 905 to slide left and right continuously in the fifth hydraulic chamber 904. The fifth hydraulic rod 905 will continuously push the liquid through the first hose 906 and the second hose 903, so that the sixth hydraulic rod 902 will continuously expand and contract in the sixth hydraulic chamber 901.

The first piston rod 108 penetrates and is slidably connected to the upper part of the housing 1. The first piston rod 108 is L-shaped. The first piston rod 108 is fixedly connected to the right side of the first hydraulic rod 502. The second piston rod 109 is fixedly connected to the upper part of the second rack 105.

[0032] When the equipment is specifically used, when the coal on the second sieve plate 4 increases and its weight drives the second sieve plate 4 and the frame 3 to descend, the first piston rod 108 will also be driven to descend as the first hydraulic rod 502 descends. The liquid in the hydraulic pipe 107 will be driven by the descent of the first piston rod 108, causing the second piston rod 109 to rise in the hydraulic pipe 107. The second rack 105 will be driven to rise by the rise of the second piston rod 109. The second rack 105 will slide upward on the backing plate 106. The second gear 104 will be driven to rotate counterclockwise by the rise of the second rack 105. The rotating rod 101 will be driven to rotate counterclockwise by the rotation of the second gear 104. The rotating rod 101 will drive the connecting bar 102 to make the baffle 103 closer to the first sieve plate 2, thereby blocking the coal rolling on the first sieve plate 2 to reduce the amount of coal falling onto the second sieve plate 4.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
