Description

Technical Field

[0001] The utility model relates to the technical field of carbon black production, in particular to a fine powder filtering device for carbon black production. Background Technique

[0002] Carbon black, also known as carbon black, is an amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. The one made from natural gas is called "gas black", the one made from oils is called "lamp black", and the one made from acetylene is called "acetylene black". In addition, there are also "channel black" and "furnace black". According to the properties of carbon black, there are "reinforcing carbon black", "conductive carbon black", "abrasion-resistant carbon black", etc. It can be used as a black dye for manufacturing Chinese ink, printing ink, paint, etc., and is also used as a reinforcing agent for rubber. The existing fine powder filtering device for carbon black production (publication number: CN218655408U) exposes at least the following defects in use:

[0003] In the above scheme, during long-term use, a large amount of large-particle carbon black will accumulate on the upper surface of the filter screen, and finally the filter holes on the filter screen will be blocked, resulting in the filter screen being unable to be used and needing to be cleaned. However, the filter screen in the above scheme is fixed between the inner walls of the housing and is difficult to disassemble and replace, resulting in troublesome maintenance of the device. Therefore, a fine powder filtering device for carbon black production is developed. Content of the Utility Model
