MATERIAL FEEDING HOPPER FOR VERMICULITE BOARD PRODUCT MACHINE

摘要

PURPOSE: A hopper for material filling of vermiculite board manufacturing device is provided to uniformly filling materials into vermiculite board molding/metal molds by generating vortex inside the hopper housing. CONSTITUTION: A hopper for material filling of vermiculite board manufacturing device comprises housing, a fitting(20), a filter(30) and a second air supply pipe(40). The hopper housing comprises a first main body, a secondary body(12), a first pipe(14) and a second pipe(15). In the fitting, a first hole(23) is formed. In the pipe(21) projected to one side, a second hole(22) is formed. The air from the air supply pipe passes through to the first hole. The fitting is assembled in flanges(16) formed in the second pipe of the fitting in the hopper housing. The projected pipe is located inside the second pipe. The filter is assembled at the end of the pipe in the fitter and prevents backflow of the materials inside the hopper housing. The second air supply tube is fixed to the fitter and provides air inside the hopper housing.
