Large coating lump removing device

Abstract

Rear ends of pushing rodsare axially connected to a support base, which is movably engaged with guide rails. A drive unitis disposed to rotatably move wire beltsbetween wheelsandat longitudinal front and rear ends of the guide rails, and the support baseis connected to the wire belts. The drive unitis activated to guide the pushing rodsby the guide railsso to make pushing and pulling operation of the pushing rods. A doorwhich is disposed at the back wall of a static gratein a clinker cooleris opened to fit the pushing rodsinto a seal materialon the opening to push a large lump of coating Cretained on the static grate. The pushing rodshave a double tube structure and are cooled by injecting cooling water from supply pipes By configuring as described above, there is provided an advantageous apparatus for removing large lumps of coating which can remove the large lumps of coating retained in a clinker cooling section with reliability without manually working and automate the removing work, and which excels in maintenance and management.
