Description
Technical Field
[0001] The utility model relates to the field of blue coke crushing, in particular to a crusher for blue coke. Background Art
[0002] Lignite is made by burning clean coal blocks. As a new type of carbon material, it has the characteristics of high fixed carbon, high specific resistivity, high chemical activity, low ash content, low aluminum, low sulfur and low phosphorus. It is gradually replacing metallurgical coke and is widely used in the production of calcium carbide, ferroalloys, ferrosilicon, silicon carbide and other products, becoming an irreplaceable carbon material. Lignite can replace coke (metallurgical coke) and is widely used in chemical, smelting, gasification and other industries. In its preparation process, the crushing of medium coal is an indispensable link.
[0003] However, the medium coal crushers used in the production of lignite in the prior art still have some shortcomings during use. For example, most of them are crushed by single-sided moving plates and static plates, resulting in low crushing efficiency, which in turn leads to slow lignite preparation efficiency and prolonged working cycle. At the same time, the coal material after crushing cannot be preliminarily and efficiently screened, resulting in poor accuracy, poor practicality and convenience. At the same time, the dust generated during crushing cannot be accurately removed, which can easily lead to environmental pollution, and accidental inhalation by workers can easily affect their health.
[0004] After searching Chinese patents: A medium coal crusher for semi-coke production (publication number: CN214553815U), including a machine body, a feed hopper fixedly connected to the top of the machine body, static plates fixedly connected to both sides of the inner wall of the machine body, a moving plate provided on the inner side of the static plate, and a transmission mechanism provided on the inner side of the moving plate. In the medium coal crusher for semi-coke production, the rotating rods on both sides can drive the moving plates on both sides to swing alternately with the circular motion of the coaxial hinge points at the inner ends of the two pull rods, and then cooperate with the static plates to crush the coal on both sides of the machine body at the same time, greatly improving the crushing efficiency, thereby making the preparation efficiency of semi-coke higher, shortening the working cycle, and screening the crushed coal to make it more accurate, and the screening efficiency is fast, and the coal that does not meet the standards can be automatically exported, which is more practical and convenient. Through the connection between the main pipe and the branch pipe, the dust generated by the crushing of the moving plates and static plates on both sides can be accurately removed, thereby reducing environmental pollution and avoiding accidental adsorption of workers and affecting their health.
[0005] Although the above patent can achieve precise dust removal for the dust generated when the moving plates and the static plates on both sides are crushed, thereby reducing environmental pollution; however, some lignite will not be completely crushed during the crushing process, and the staff will need to manually transport the incompletely crushed lignite into the crusher for secondary crushing. This method of manually transporting the incompletely crushed lignite will increase the labor intensity of the staff.
[0006] Therefore, it is necessary to invent a crusher for blue coal to solve the above problems. Utility Model Content
