Latest Patents
One of Matthews' latest inventions is the Electro-hammer rapper. This device features an electromagnetic hammer rapper with forward and retract coils. It is designed to controllably cause a centrally disposed armature to impact an impact transfer pin, effectively knocking off slag and other encrustations from heat transfer tubes or walls of heat exchanger components. The device includes an electrical circuit for controlling the energization of the coils, along with a manually actuatable switch for initiating impacts. Additionally, an auto sequencer/manual selector circuit manages the coils of multiple electromagnetic solenoids, enhancing operational efficiency.
Another significant invention is the indexing sootblower. This long retracting sootblower is utilized for boiler cleaning and features a lance tube that advances into and out of a boiler while simultaneously rotating. The sootblower includes nozzles that discharge a jet of blowing medium, tracing helical paths. An indexing mechanism allows for the repositioning of these helical paths between actuation cycles, minimizing boiler erosion and mechanical stress.
