Изобретение относитс к области переработки отходов древесины.The invention relates to the field of waste wood processing.
Известен способ производства древесноволокнистой массы путем пропарки щепы насыщенным паром при перемешивании с последующим размолом.A known method for the production of wood fiber mass by steaming chips with saturated steam with stirring, followed by grinding.
Недостатками известного способа вл ютс низкое качество получаемой древесноволокнистой массы и низка производительность вследствие длительности операции пропаривани .The disadvantages of this method are the low quality of the resulting fibrous mass and low productivity due to the duration of the steaming operation.
Цель изобретени - упрощение процесса и повыщение качества древесноволокнистой массы . Это достигаетс тем, что пропарку щепы ведут насыщенным паром с температурой 190-210°С в течение 0,5-2 мин.The purpose of the invention is to simplify the process and increase the quality of the pulp. This is achieved by steaming the chips with saturated steam at a temperature of 190-210 ° C for 0.5-2 minutes.
Щепа подаетс из рубительной машины при помощи ленточных или скребковых конвейеров в бункер. Из бункера щепа поступает по вибрациоппому лотку в приемную воронку шнека дефибратора. Дефибратор состоит из двух камер: поперечной и размольной. Сначала щепа подаетс шнеком в пропарочную камеру, куда поступает насыщенный пар с температурой 190-210С. Длительность пропарки 0,5-2 мин. Затем щепа, наход ща с в пропарочной камере, вытесн етс новойChips are fed from the chipper using belt or scraper conveyors to the hopper. From the bunker, the chips enter through the vibrating tray into the receiving hopper of the defibrator auger. The defibrator consists of two chambers: transverse and grinding. First, the chips are fed by the screw into the steam chamber, where saturated steam with a temperature of 190-210 ° C flows. Duration of steaming 0.5-2 minutes. Then the chips in the steaming chamber are replaced by a new
порцией щепы в размольную камеру, содержащую два диска: неподвижный и вращающийс . Размолота щепа представл ет собой древесную массу со степенью помола 22-26 ДС, котора подаетс в циклон, а затем -a portion of the chips in the grinding chamber containing two disks: stationary and rotating. The milled chips are wood pulp with a grinding degree of 22-26 DS, which is fed to the cyclone and then
на линию производства древесноволокнистых плит.on the production line of fibreboard.
Предмет изобретени Subject invention
Способ производства древесноволокнистой массы путем пропарки щепы, например, из отходов лесозаготовок насыщенным паром при перемешивании с последующим размолом, отличающийс тем, что, с целью упрощени A method for producing a wood fiber mass by steaming chips, for example, from logging wastes with saturated steam with mixing and subsequent grinding, in order to simplify
процесса и повышени качества древесноволокнистой массы, пропарку щепы ведут насыщенным паром с температурой 190-210°С в течение 0,5-2 мин.process and improve the quality of wood pulp, steaming chips are saturated steam with a temperature of 190-210 ° C for 0.5-2 minutes.
