Different methods of connection of the dust collecting skeleton

(1) connection ring type: fasten the horizontal rings of the two skeletons in the semicircular grooves of the connection ring. The connection ring type is a relatively stable connection method, but its processing procedures are relatively cumbersome, the cost is high, but the strength and verticality are better. Currently, many large filter bag dust removal kits and dust removal skeletons use this method of connection.

(2) mandrel type: make matching positive and negative mandrels, welded into two sections of the bag cage. The mandrel type connection has better rectitude than other connection methods. It has the following advantages: firm connection, easy disassembly and maintenance, good straightness, and less filter bag wear during spraying.

(3) insertion type: the steel wire is stamped and shaped with an abrasive tool, and the steel wire becomes trapped in the horizontal ring of another skeleton when connected. The socket skeleton is an older connection method. It does not require transition joints and the price is relatively low, but it has little connection stability and little overall straightness. Not suitable for use in places with strong external force and vibration. There are many points of contact with the filter bag, which can easily break the filter bag and affect the life of the filter bag.
