Description
Technical Field
The utility model relates to a self-cleaning formula air cleaner filter core of riveting formula pulse.
Background
At present, the fixing and sealing of the filter element of the drum type air filter have two basic modes of fastening a lower end cover plate through a mandrel bolt and fastening an upper end cover plate through an eccentric compression bar. The filter element fixed and sealed by the upper cover plate generally has the advantages of convenient assembly and disassembly of the filter element, high working efficiency, good manual working environment and the like, and is widely applied to air purification equipment. However, in the air cleaning apparatus using the pulse back washing, in the case of the filter element using the fastening manner of the upper end cover plate, an accident that the upper end cover plate or the lower end cover plate is knocked off may occur during the pulse back washing. Once the filter element cover plate falls off, if the filter element cover plate is not found in time and is immediately shut down to replace the filter element, dirty air which is not subjected to purification treatment can directly enter the air utilization equipment, so that the air utilization equipment or an air purification workshop is greatly damaged in production. In China, a serious accident that a gas turbine with the value of over hundred million yuan is damaged because the end cover plate of the filter element falls off and is not found in time is caused by the consideration of the conventional manufacturing process or the production cost, and the production process of the filter element at home and abroad is to bond the filter cylinder on the upper end cover plate and the lower end cover plate by using a bonding agent. Although the adhesive and the bonding process are different, the upper end cover or the lower end cover of the filter element falls off in the using process, including top-grade filter element manufacturers in the world; foreign famous filter element manufacturers try to change the joint surface of the end cover and the filter cylinder, namely increase the contact surface and change the stress direction, and a plurality of bosses are punched on the end cover plate, but the foreign famous filter element manufacturers still do not help, and the cover plate falling-off accident also occurs.
At present, the filter cartridge is adhered to the upper and lower end cover plates by using an adhesive in the production process of the filter cartridge at home and abroad in consideration of the conventional manufacturing process or the production cost. Although the adhesive and the bonding process are different, the upper end cover or the lower end cover of the filter element falls off in the using process, including top-grade filter element manufacturers in the world; foreign famous filter element manufacturers try to change the joint surface of the end cover and the filter cylinder, namely increase the contact surface and change the stress direction, and a plurality of bosses are punched on the end cover plate, but the foreign famous filter element manufacturers still do not help, and the cover plate falling-off accident also occurs.
