Description

Technical Field

[0001] The utility model relates to the technical field of charcoal crushing, in particular to a sustainable secondary crushing and conveying device. Background Art

[0002] Charcoal is a dark brown or black porous solid fuel left after incomplete combustion of wood or wood raw materials, or pyrolysis under air-tight conditions. Charcoal is an impure amorphous carbon that retains the original structure of wood and residual tar in the pores. Charcoal was used in the smelting of bronze ware in the Shang Dynasty and iron ware in the Spring and Autumn and Warring States Periods in China, and its hygroscopicity was used to observe climate change. In recent years, my country's charcoal industry has developed rapidly, and the development of the charcoal industry in the domestic and international markets is very promising. Some existing charcoal crushers generally require secondary screening to ensure the crushing quality of charcoal after crushing the charcoal raw materials. Not only is the efficiency low, but also multiple sets of equipment are required to carry out crushing, screening and other steps, which is costly. Utility Model Content

[0004] The purpose of the utility model is achieved through the following technical solutions: a sustainable secondary crushing and conveying device, including an outer shell, in which a rotatable pre-crushing roller and a crushing roller are installed, the crushing roller is located below the pre-crushing roller, an inclined plate corresponding to the crushing roller is installed in the outer shell, and a screen corresponding to the crushing roller is installed at the discharge end of the inclined plate.

[0005] A further technical solution is that a baffle plate matched with the screen is installed at the bottom of the crushing roller, an inclined auger is installed at the discharge end of the baffle plate, and the discharge end of the auger extends to the outside of the outer shell.

[0006] A further technical solution is that a brush corresponding to the pre-crushing roller is installed on the inner side wall of the outer shell, and the brush is in contact with the surface of the pre-crushing roller.

[0007] A further technical solution is that a negative pressure suction machine is installed on the outer shell, the suction end of the negative pressure suction machine is connected to the feed port on the outer shell, and the discharge end of the negative pressure suction machine corresponds to the inclined plate.

[0008] A further technical solution is that a wear-resistant layer is provided on the side of the screen close to the crushing roller.

[0009] The utility model has the following advantages: the utility model can pre-crush the charcoal material by arranging the pre-crushing roller, which is convenient for subsequent crushing by the crushing roller and improves the crushing efficiency of the equipment; the crushing roller and the screen are arranged to cooperate to crush the pre-crushed charcoal and avoid the falling of oversized materials, thereby improving the crushing quality; the negative pressure suction machine can reduce the emission of dust and protect the environment; and the wear-resistant layer on the screen can extend the service life of the screen.
