Description

Technical Field

[0001] This utility model belongs to the field of mechanical cleaning technology, specifically, it relates to a coal cup pressure plate and a cup bottom cleaning device. Background Technology

[0002] The plastic layer index is an important indicator for judging the coking properties of coal and plays a crucial role in guiding coking coal blending. Furthermore, the plastic layer index is also an important indicator for enterprises in coal price settlement. Therefore, accurate measurement of the plastic layer index is of great significance to enterprises. The coal cup used for plastic layer testing mainly consists of a cup body, a cup bottom, and a pressure plate. After the test, the coke residue adhering to the coal cup needs to be thoroughly cleaned. In related technologies, the cleaning method generally adopted is as follows: the coal cup is fixed on the connecting plate, the motor is started to rotate the coal cup, and the inspector uses a wooden stick wrapped with sandpaper to polish it to remove the coke residue from the cup body; the inspector uses steel cones or needles of different diameters to clean the gas vents on the cup bottom and pressure plate one by one to remove the coke residue from the pressure plate and cup bottom. Besides the above manual cleaning method, most current cleaning technologies improve the cleaning of the coal cup body by adopting automated cleaning methods, while automated cleaning of the coal cup bottom and pressure plate is rarely addressed. The following are the disadvantages of manually cleaning the bottom of the cup and pressure plate: it is dangerous for the inspector to use a steel rod or needle to clean the bottom of the cup and pressure plate; it is easy to miss some gas vents when cleaning manually, resulting in incomplete cleaning; there are a large number of gas vents on the bottom of the cup and pressure plate, and it is time-consuming and laborious to clean them one by one by manual, which affects the testing efficiency; coal dust is generated during the cleaning process, which not only pollutes the environment, but also poses certain health hazards to the inspector.

[0003] Therefore, developing a coal cup pressure plate and a bottom cleaning device that automatically cleans the coal cup without requiring manual cleaning by inspectors is an urgent technical problem to be solved. Utility Model Content
