Fibreboard production line wet process

摘要

The invention relates to wood processing industry, in particular to the production of fibreboard and can be used to create lines for production of ecologically clean wet fibreboard process. The object of the utility model is to provide the possibility of manufacturing on the line of environmentally friendly fibreboard wet method by using enzyme technology. manufacturing line for fibreboard wet process comprises consecutively installed and technologically connected portions 1, 2 and 3, respectively shredding wood raw material, the grinding of wood chips, pools 4, 5 and 6 respectively, for preparing rafinatornoy wood fiber mass, for the preparation of micronised wood fiber mass and for circulating water , portions 7 and 8 respectively, for the preparation of a binder and additives, boxes 9 and 10, respectively sizing rafinatornoy micronised mass and weight, casting machines 11, hot press 12 and the format-edger 13. Line 14 is provided with a portion of the enzyme preparation, and pool 5 for preparing micronised mass provided with a conduit 15 connecting it to the portion 14 of the enzyme preparation. Wood raw material supplied to the grinding section 1 the wood raw material on which it is manufactured from wood chips. Technological chips fed into sections 2 and 3 respectively on the grinding rafinatornuyu wood-fiber mass for the main layer hardboard and fibreboard weight of finely ground surface (humanized) plate layer. At the station 14 is carried out the preparation of the working enzyme solution. Milled wood fiber mass enters the pool 4 and 5, respectively to prepare rafinatornoy wood fiber mass and for preparation of micronised pulp, where it is diluted with white water to give a suspension. Work enzyme solution section 14 via line 15 is directed into the pool 5 micronised wood fiber mass. The finished wood fiber mass suspension is fed into boxes 9 and 10, respectively sizing rafinatornoy wood fiber mass and micronised pulp, where it serves cooked portion 8 Additives (hydrophobing agent, precipitant and others.). Glued wood-fiber mass fed to a casting machine; 11, where the carpet is molded from the core and surface layers, the finished carpet is divided into blanks, which are loaded into a hot press 12. The pressed fibreboard directed to dimensioning edger 13, followed by storage or subsequent processing (e.g., heat treatment).; 2 PF-ly, ly-1 nez.p.f
