Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing honeycomb SCR denitration catalysts, in particular to an automatic filter screen replacement device for pre-extrusion of honeycomb SCR denitration catalysts. Background Technique

[0002] Honeycomb SCR denitration catalysts are commonly used in alumina clinker kilns and waste incineration kilns. The production process of honeycomb SCR denitration catalysts is: mixing, pre-extrusion filtration, extrusion, first-stage drying, second-stage drying, furnace calcination, cutting, and packing. And honeycomb SCR denitration catalysts have very high requirements for the purity of the mud during the production process. During the production process, the pre-extrusion filtration process can effectively filter out the impurities contained in the mixed mud, ensuring the smooth progress of the subsequent catalyst during the extrusion molding process.

[0003] A pre-extrusion device for honeycomb SCR denitration catalysts with the Chinese authorized publication number of CN 210934991 U, through the adjustment and design of its internal structure, reduces the pre-extrusion resistance. Therefore, on the one hand, the extrusion speed increases significantly, with an increase of more than 20%. On the other hand, the shape of the pre-extruded material changes significantly, changing from a cylindrical rod shape to a thin noodle shape.

[0004] However, there are still some deficiencies in the use of this patent. When performing pre-extrusion operations, it is generally necessary to filter the internal impurities. The filter screen is usually fixed inside the extruder. When the filter screen is completely blocked and cannot be used, the extruder must be shut down to replace the filter screen. And after replacing the filter screen, there will still be impurities remaining in the extruder, and the replaced filter screen will still be quickly blocked by impurities. Therefore, it affects normal production, wastes a lot of time, and reduces production efficiency. Content of the Utility Model
