Description
Technical Field
[0001] The present application relates to the technical field of nano-microporous thermal insulation board production equipment, and specifically to a stirring device for wet molding of nano-microporous thermal insulation boards. Background Art
[0002] When the nanoporous insulation board is produced by the dry process, after the nanoporous insulation board is pressed and formed, it needs to first pass through a cleaning line, use a brush to sweep away the dust on the surface of the nanoporous insulation board, and then use a nozzle to spray the gel liquid onto the outer surface of the nanoporous insulation board, so that a gel layer can be formed on the outer surface of the nanoporous insulation board.
[0003] Since the nano-board produced by dry method is seriously powdered, it is not easy to fuse with other refractory materials such as refractory mud and castables, which eventually reduces the service life of the nano-board. In order to improve the service life of the nano-board, the wet forming process of nano-microporous insulation board came into being. The wet forming process of nano-microporous insulation board is to add gel-type binders to the dry powder raw materials to form a semi-wet mixture before carrying out subsequent process steps. Since gel exists inside the nano-microporous insulation board, it can effectively alleviate the powdering problem of the nano-board surface.
[0004] When mixing dry powder raw materials and gel binders, stirring equipment is required. Conventional stirring equipment will generate dust overflow during stirring, affecting the working environment.
