Description

Technical Field

[0001] The utility model relates to the technical field of coal blending and coking, in particular to a dust-proof coal blending and coking device. Background Art

[0002] Coal blending involves combining coking coals of varying degrees of metamorphism in appropriate proportions. Coals of varying degrees of metamorphism each have their own unique characteristics and play different roles in coal blending. Leveraging the complementary properties of various coals to ensure that the blended coal quality meets coking production requirements is crucial for the rational utilization of coal resources, conservation of high-quality coking coal, and expansion of coking coal resources. A sound coal blending plan can fully leverage the unique characteristics of each coal type and improve coke quality. Given the specific conditions of my country's coal resources, the use of blended coal for coking not only rationally utilizes coking coal resources across various regions but also serves as a fundamental measure for expanding coking coal use.

[0003] For example, Chinese patent CN218590747U discloses the following technical solution: a coking coal blending device is disclosed, which relates to the field of coking coal blending technology, including a feed box, a lifting pipe, and a conveying pipe. A dust suppression mechanism is installed on the top of the feed box, a crushing mechanism 1 is installed on the bottom of the feed box, a crushing mechanism 2 is installed between the lifting pipe and the conveying pipe, the crushing mechanism 2 includes a connecting frame, a motor 4 is fixed to one side of the connecting frame, and two crushing rollers 2 are rotatably connected to the internal part of the connecting frame, one end of which is fixed to the output shaft of the motor 4, a motor 2 is fixed to one end of the lifting pipe, an auger 1 is connected to the output end of the motor 2, a screening net is provided on part of the side of the lifting pipe, and the crushing mechanism 1 includes a crushing box, a motor 1 is installed on one side of the crushing box. The utility model can re-crush coking coal that has been screened out of larger particles, without having to transfer it to another crushing side for crushing and re-loading before use, thereby improving the efficiency of coking coal blending.

[0004] However, in actual use, the above device places the raw materials inside the feed box. When the raw materials flow to the crushing mechanism, under the action of gravity, the falling speed of the raw materials will gradually decrease, and the raw materials cannot be fed at a uniform speed. At the same time, the raw materials will accumulate inside the crushing mechanism, affecting the crushing effect. Utility Model Content
