Description

Изобретение относится к устройству рубительных машин и может быть использовано в целлюлозно-бумажной и других отраслях промышленности.The invention relates to a device for chipping machines and can be used in pulp and paper and other industries.

Известна рубительная машина, вклю чающая ножевой диск, загрузочный патрон, кожух ножевого диска [Ί].A chipping machine is known, including a knife disc, a loading chuck, a blade disc casing [Ί].

Известна также рубительная машина, включающая кожух, в котором размещен ножевой диск, загрузочный патрон [2].Also known is a chipping machine, including a casing in which a knife disc is placed, a loading cartridge [2].

Недостатком известных машин является сложность конструкции.A disadvantage of the known machines is the design complexity.

Цель изобретения - упрощение конструкции.The purpose of the invention is to simplify the design.

Указанная цель достигается тем, что машина снабжена устройством для защиты щепы от повреждений в виде кольцеобразного спрьУска для подачи жидкости, который установлен внутри кожуха в зоне факела щепы.This goal is achieved by the fact that the machine is equipped with a device for protecting chips from damage in the form of an annular spray for supplying liquid, which is installed inside the casing in the zone of the flare chips.

На фиг. 1 изображена рубильная машина, продольный разрез} на фиг.2разрез А-А на фиг. 1; на фиг. 3 “ узел 1 на фиг. 1 (закрепление спрыска на кожухе рубительной машины).In FIG. 1 shows a chipper, longitudinal section} in FIG. 2, section AA in FIG. 1; in FIG. 3 “node 1 in FIG. 1 (fixing the spray on the casing of the chipper).

Рубительная машина включает станину 1, с расположенными на ней подшипниками 2, в которых закреплен вал 3 с ножевым диском 4 и укрепленными на нем лопатками 5. Ножевой диск 4 закрыт кожухом 6 с окном 7 для выброса щепы. Загрузочный патрон 8 с древесиной 9 закреплен напротив ножевого диска 4. Спрыск 10 закреплен с приводной стороны ножевого диска 4 на кожухе 6, например, при помощи гаек 11 и 12. Подача воды в спрыск 10 производится гиб— -ким шлангом (не показан)через штуцер 13. При прохождении через спрыск воды распыляется, образуя струи 14. При измельчении древесины 9 щепа образует факел 15.The chipper includes a bed 1, with bearings 2 located on it, in which a shaft 3 is fixed with a knife disk 4 and blades mounted on it 5. The knife disk 4 is closed by a casing 6 with a window 7 for chip discharge. A loading cartridge 8 with wood 9 is fixed opposite the knife disk 4. Spray 10 is mounted on the drive side of the knife disk 4 on the casing 6, for example, using nuts 11 and 12. The water is supplied to the spray 10 by a flexible hose (not shown) through fitting 13. When passing through a spray of water is sprayed, forming a stream 14. When chopping wood 9 wood chips forms a torch 15.

Рубительная машина работает следующим образом.Chipping machine operates as follows.

Факел 15 щепы, образующейся при рубке древесины 9, ударяется в зад нюю стенку кожуха 6. Затем щепа, подхватываемая лопатками 5, удаляется из кожуха 6 через окно 7 для ь.«браса .щепы.The torch 15 of the chips generated during the felling of wood 9 strikes the rear wall of the casing 6. Then, the chips picked up by the blades 5 are removed from the casing 6 through the window 7 for the chip.

В руби?ельной машине частички' ще~ пы смачиваются водой, распыляемой в виде струй 14 спрыском 10. Для улучшения эффективности смачивания спрыск 10 устанавливается в зоне факела 15 щепы, причем кольцевая форма спрыска 10 обеспечивает полное смачивание частиц щепы в зоне факела 15»In a rubbing machine, particles of the chip are wetted with water sprayed in the form of jets 14 with spray 10. To improve the wetting efficiency, spray 10 is installed in the zone of the flare 15 of the chip, and the annular shape of the spray 10 provides complete wetting of the particles of the chip in the zone of the flare 15 ”

При смачивании частичек щепы водой снижается гидравлическое сопротивление потоку, а также коэффициент трения частичек щепы о стенки кожуха 6 (вода играет роль смазки). Вследствие этого уменьшается повреждаемость щепы из-за смятия кромок при ударах и трении частичек щепы о стенки кожуха 6 и друг о друга. Кроме того, снижение гидравличес кого сопротивления в потоке щепы обеспечивает уменьшение энергоемкости процесса ее транспортирования.When wetting the particles of wood chips with water, the hydraulic resistance to flow decreases, as well as the coefficient of friction of the particles of wood chips on the walls of the casing 6 (water plays the role of a lubricant). As a result, the damage to the chips due to crushing of the edges during impacts and friction of particles of chips on the walls of the casing 6 and against each other is reduced. In addition, a decrease in hydraulic resistance in the chip flow reduces the energy consumption of the process of its transportation.

Claims

The invention relates to a device for chippers and can be used in the pulp and paper and other industries. Known chipping machine, including a knife disc, boot chuck, knife disc casing. Also known chipping machine, including a casing in which the knife disc is located, boot cartridge 2. A disadvantage of known machines is the complexity of the design. The purpose of the invention is an ynptxieHijie structure. This goal is achieved by the fact that the machine is equipped with a device for protecting the chips from damage in the form of an annular sprit for supplying liquid, which is installed inside the casing in the area of the chip plume. FIG. 1 shows a chipper, a longitudinal section in FIG. 2, a section A-A in FIG. one; in fig. 3 node 1 in FIG. 1 (fixing the shower on the casing of the chipper). The chipper includes a frame 1, with bearings 2 on it, in which shaft 3 is fixed with a blade disk 4 and blades 5 fixed on it. The blade disk is covered by a casing 6 with window 7 for ejection of chips. The boot cartridge 8 with wood S is fixed in front of the knife disc k. Hopper 10 is fixed on the drive side of the blade disc to the casing 6, for example, by means of nuts 11 and 12. Water is fed into the shower 10 by a flexible hose (not shown) through fitting 13. When passing through the shower it is sprayed to form a jet I. chopping the wood 9, the chips form a flare 15. The chipper operates as follows: The torch 15 of the chips formed when chopping wood 9 hits the rear wall of the casing 6, then the chips are picked up by the blades 5 removed from the casing 6 through the window 7 of the beam, B Breaker machine particles u g They are sprayed with water sprayed in the form of jets 1 by injection 10. To improve the efficiency of wetting, a shower 10 is installed in the plume zone 15, and the circular shape of the shower 10 ensures the wetting of chip particles in the zone of flame 15. When the depot particles are wetted, hydraulic resistance decreases during wetting. flow, as well as the coefficient of friction of the chip particles against the walls of the casing 6 (water plays the role of lubricant) As a result, the damage to the chips is reduced due to the sm edge on impact and friction of the chip particles against the wall 1/1 of the casing 6 and each other. In addition, the reduction of the hydraulic flow of the chip stream reduces the energy consumption of the process of transporting it. Formula of the Invention Chi machine j includes a casing, which contains a blade disk and a loading cartridge, so that construction, the machine is equipped with a device to protect the chips from damage B form of a ring, e-shaped drop for the supply of fluid, which is installed inside the casing in the flare zone of the flail Sources of information taken into account during the examination U Author th Certificate USSR if kQk (22, l. 27 August 11 I / OZ, 1973.
