Description

Technical Field

[0001] This utility model belongs to the energy field, specifically relating to a coal powder conveying and filtering device for preventing clogging. Background Technology

[0002] Pulverized coal is a fine particulate fuel with a particle size between 0.05 and 0.1 mm, produced from coal through processes such as crushing, grinding, and drying. It features high specific surface area, strong fluidity, and high combustion efficiency (thermal efficiency can reach over 90%), and is widely used in thermal power generation, blast furnace injection in metallurgy, cement production in building materials, and coal gasification in chemical industry.

[0003] During the coal powder conveying and filtration process, the coal powder may contain large particles of impurities or foreign objects. After prolonged use, these impurities tend to accumulate on the filter components of traditional filter devices, causing blockages and affecting the normal conveying and filtration efficiency of the coal powder. This can even lead to the shutdown of the entire conveying system for maintenance. Furthermore, when the filter device is blocked or after filtration is completed, cleaning the filtered impurities is often quite troublesome, requiring the disassembly of multiple components to remove the impurities. This not only increases the workload and time cost of cleaning but may also affect the sealing performance and service life of the device.

[0004] Therefore, existing coal powder filtration devices suffer from clogging and difficulty in cleaning filtered impurities during use. Utility Model Content

[0005] In order to overcome the problems of clogging and inconvenience in cleaning the filtered impurities in existing coal powder filtration devices, a clogging-proof coal powder conveying and filtration device is proposed.
