(54) УСТАНОВКА ДЛЯ ПРОИЗВОДСТВА УПЛОТНЕННОЙ ДРЕВЕСИНЫ(54) INSTALLATION FOR PRODUCTION OF COMPRESSED WOOD

:.:.::lJ:.:. :: lJ

Изобретение относитс  к области изготовлени  уплотненной древесины, а именно к установкам дл  ее производства.The invention relates to the field of manufacturing compacted wood, in particular to installations for its production.

Известные установки дл  указанных целей осуществл ют технологический процесс последовательно и состо т из нескольких различных ,по своему назначению устройств, которые предназначены, в основном, дл  выполнени  трех главных последовательных этапов: пластификации , механического уплотнени  и сушки .The known installations for these purposes carry out the technological process sequentially and consist of several different, by their design, devices, which are mainly designed to perform three main successive steps: plasticization, mechanical compaction and drying.

С целью комплексного осуществлени  пластификации , уплотнени  и сушки древесины в предлагаемой установке внутри герметизированной камеры смонтирован прессовый стол и вентил тор, в стены камеры встроены вертикально расположенные силовые цилиндры, свободный конец штока каждого из которых, наход щийс  внутри камеры, снабжен прессовой плитой, а дополнительное оборудование дл  цодачи и отвода газообразных химических веществ выполнено с трубопроводом, соединенным непосредственно с установкой дл  подачи аммиака под давлением.In order to complete the plasticization, compaction and drying of wood in the proposed installation, a press table and a fan are mounted inside the sealed chamber, vertically located power cylinders are embedded in the chamber walls, the free end of each rod, inside the chamber, is equipped with a press plate, and The equipment for the flow and removal of gaseous chemicals is made with a pipeline connected directly to a pressurized ammonia plant.

На чертеже схематически изображена описываема  установка.The drawing shows schematically the described installation.

Она содержит герметизированную камеру, котора  снабжена дополнительным оборудованием дл  подачи и отвода жидких или газообразных химических веществ и включает емкость 2 аммиака, трубопровод 3 его подачи, редукционный клапан 4, вакуум-насос 5, трубопровод 6 всасывани , вентили 7, 8 и предохранительный клапан 9. Система механического уплотнени  древесины (предназначена дл  уплотнени  заготовок и -состоит из станции гидропривода 10, трубопроводов 11 подвода масла и гидроцилиндров 12, на штоках 13 -которых установлены прессовые плиты 14,It contains a sealed chamber, which is equipped with additional equipment for supplying and discharging liquid or gaseous chemicals and includes ammonia tank 2, supply pipe 3, pressure reducing valve 4, vacuum pump 5, suction pipe 6, valves 7, 8 and safety valve 9 The system of mechanical compaction of wood (intended for compaction of workpieces and consists of a hydraulic drive station 10, pipelines 11 for supplying oil and hydraulic cylinders 12, on which rods 13 are installed press plates 14,

передающие давление на заготовки 15 древесины , которые уложены между недеформирующими плитами 16 на тележке 17.transmitting pressure on the workpiece 15 wood, which are laid between non-deforming plates 16 on the trolley 17.

Система обезвоживани  предназначена дл  обеспечени  необходимых параметров и услоВИЙ нового сушильного агента - аммиачнооаровой среды. В нее вход т: трубопроводы 18, 19 - пара и 20, 21 - конденсата с вентил ми 22-24, калориферы 25, вентил тор 26 и труба 27 дл  сброса пара с вентилем 28.The dewatering system is designed to provide the necessary parameters and conditions for a new drying agent, the ammonia-air environment. It includes: pipelines 18, 19 - steam and 20, 21 - condensate with valves 22-24, heaters 25, fan 26 and pipe 27 for steam discharge with valve 28.

Работает установка следующим образом.The installation works as follows.

Заготовки 15 натуральной древесины укладываютс  на тележку 17. Между заготовками став тс  недеформирующие плиты 16. После оформлени  штабел  тележка загружаетс  вThe natural wood blanks 15 are placed on the trolley 17. Non-deforming plates 16 are placed between the blanks. After making the stack, the trolley is loaded into

герметическую камеру 1, котора  закрываетс . Затем открываетс  вентиль 7 и включаетс  вакуум-насос 5. Установка вакуумируетс  по заданному режиму, после чего вентиль 7 закрываетс  и вакуум-насос выключаетс . Поsealed chamber 1, which is closed. Then the valve 7 is opened and the vacuum pump 5 is turned on. The installation is evacuated according to a preset mode, after which the valve 7 is closed and the vacuum pump is turned off. By

трубопроводу 3 при открытом вентиле 8 изpipeline 3 with open valve 8 of

емкости 2 в установку подаетс  газообразный аммиак, давление которого регулируетс  редукционным клапаном 4. Дл  одновременного подогрева заготовок в калориферы 25 через вентиль 23 пускаетс  шар. После олределенного , установленного режимом времени воздействи  на заготовки температуры и аммиака вентиль 8 закрываетс , прекращаетс  доступ газообразного аммиака, включаетс  вентил тор 26 и /начинаетс  процесс сушки древесины в аммиачно-паровой среде. Одновременно с .включением вентил тора приводитс  в действие сталци  гидропривода 10, от которой по трубопроводам I1 на гидроадилиндры 12 .подаетс  масло.Масло передает давление на штоки 13, а установленные на них прессовые плиты 14 ПО заданной программе оказывают давление иа заготовки 15 древесины. Э процессе обезвоживани  образовавшиес  излишки пара, а также конденсат из установки удал ютс  по трубопроводу 21, открыва  вентиль 24. Конденсат из калориферов уходит по трубопроводу 20. Дл  соблюдени  нужного режима в установку по трубопроводу 19 при периодически открываемом вентиле 22 пускаетс  острый пар. По окон-чании ,процессаThe tank 2 is supplied with ammonia gas, the pressure of which is regulated by the pressure reducing valve 4. A ball is fired into the heaters 25 at the same time to heat the blanks. After the temperature and ammonia effect on the workpieces determined by the time regime and the valve 8 is closed, the access of gaseous ammonia is stopped, the fan 26 is turned on and / the wood is dried in the ammonia-steam medium. Simultaneously with the fan being turned on, the steel of the hydraulic actuator 10 is activated, from which oil is fed through pipelines I1 to the hydraulic accelerators 12. Oil transfers pressure to the rods 13, and the press plates 14 installed on them apply pressure to the wood 15. In the dewatering process, the excess steam and condensate from the plant are removed through conduit 21, opening valve 24. Condensate from the heaters goes through conduit 20. In order to maintain the desired mode, direct steam is released to the installation during conduit 19 periodically opened. By the end of the process

После о; слаждени  заготовок Действием гидроцилиндров, управл емых из станции гидропривода , они освобождаютс  от прижима, камера 1 открываетс , и тележка с уплотненной древесиной выгружаетс  из уста новки.The heating of the heaters and the fan are turned off. After about; The blanks are cooled by the action of the hydraulic cylinders controlled from the hydraulic drive station, they are released from the pressure, the chamber 1 is opened, and the cart with compacted wood is unloaded from the installation.
