Abstract

The invention discloses a manufacturing device for a big insulating cardboard with high density as well as a manufacturing method thereof. The device comprises a pulp feeding system, a pulp purifying and adjusting system, an adhesive paste paper pulp forming system and an insulating cardboard forming system. The pulp feeding system comprises a hydraulic pulp kneader, a pulp storage tank, a slag separator, a double-disc pulp grinder and a pulp forming tank which are connected sequentially through pipes. The pulp purifying and adjusting system comprises a pulp adjusting box, a desilting disc, a sand separator and a pulp separating box which are connected sequentially through pipes. The adhesive paste paper pulp forming system comprises a round net pulp spraying former, an adhesive paste paper pulp forming device and a delivering machine. The insulating cardboard forming system comprises a pre-loading machine, a board loading machine, a hot pressing machine, a board unloading machine and a board receiving table. The invention adopts pure wood pulp as a raw material, and a set of advanced devices to manufacture big insulating cardboards with high density, and a gap in the insulating cardboard manufacturing field is filled.

Description

technical field [0001] The invention relates to a manufacturing device and method of insulating cardboard, in particular to a device and a method for manufacturing high-density large-sheet insulating cardboard. Background technique [0002] High-density large-sheet insulating cardboard is mainly used to make insulating cardboard parts of transformers. The so-called high density means that the density is greater than or equal to 1.25 g / cm 3 , Large insulating cardboard refers to insulating cardboard with a length × width greater than or equal to 3 meters × 6 meters. The high-density large-sheet insulating cardboard used in the transformer industry is all manufactured by foreign equipment, and there is no report on the production equipment and manufacturing method for manufacturing high-density large-sheet insulating cardboard. Contents of the invention [0003] The object of the present invention is to provide a device and method for manufacturing high-density large-sheet...
