Description
Известны экструзионные прессы дл изготовлени древесностружечных плит, включающие пуансон и обогреваемые плиты пресса.Extrusion presses are known for producing particle boards including a core and heated press plates.
Целью изобретени вл етс интенсификаци процесса полимеризации св зующего и повыщение эффективности устройства.The aim of the invention is to intensify the binder polymerization process and increase the efficiency of the device.
Достигаетс это тем, что плиты предлагаемого пресса выполнены со сквозными отверсти ми дл подвода и отвода теплоносител , которые соединены через распределитель и трубопровод с теплообменником.This is achieved by the fact that the plates of the proposed press are made with through holes for supplying and discharging coolant, which are connected through a distributor and a pipeline to the heat exchanger.
На чертеже показана схема предлагаемого пресса.The drawing shows the scheme of the proposed press.
Пресс содержит пуансон /, плиты 2 пресса с отверсти ми 3 дл их обогрева, каналы 4 диаметром 0,8-1,0 мм дл подвода и отвода теплоносител , которые через распределитель 5 и трубопровод 6 соединены с теплообменником .The press contains a punch /, plates 2 presses with holes 3 for their heating, channels 4 with a diameter of 0.8-1.0 mm for supplying and discharging the heat transfer fluid, which are connected to the heat exchanger through distributor 5 and pipe 6.
Каналы наход тс на рассто нии 30-60 мм друг от друга.The channels are located 30-60 mm from each other.
Пресс работает следующим образом.The press works as follows.
Древесностружечна масса вводитс в канал , образованный плитами пресса 2 и проталкиваетс пуансоном /. Через отверсти 3 непрерывно вводитс теплоноситель (перегретый пар или газ) в прессуемое изделие.The wood pulp is introduced into the channel formed by the press plates 2 and pushed by the punch /. Through the holes 3, a heat carrier (superheated steam or gas) is continuously introduced into the extruded product.
На выходе пресса каналы служат дл отвода воздуха или пара и соответственно дл сун1ки плит.At the exit of the press, the channels serve to divert air or steam and, accordingly, for the suction of the plates.
