Description

Изобретение относитс  к устройствам дл  удалени  окалины.This invention relates to descaling devices.

Известны устройства дл  гидросбива, содержащие щелевые сопла с болтовой зат жкой.Water jet devices are known that contain slotted nozzles with bolt-on tightening.

Предлагаемое устройство отличаетс  тем, что оно выполнено в виде рамы с П-образными поперечинами, в которых расположены секции сопел, и снабжено торцовыми винтами дл  поджати  секций.The proposed device is characterized in that it is made in the form of a frame with U-shaped crossbars, in which the nozzle sections are located, and provided with end screws to press the sections.

На фиг. 1 показано описываемое устройство; на фиг. 2 - то же, разрез по Л-Л на фиг. 1.FIG. 1 shows the described device; in fig. 2 - the same, section on LL in FIG. one.

Верхний и нижний коллекторы собраны из секций щелевых сопел 1 в одну раму 2. Секции креп тс  между собой, с крыщкой 3 и с подвод щей стойкой 4 при помощи штифтов или цилиндрических выступов. Уплотнение создаетс  посредством кольцевых прокладок и прижимных винтов 5. Регулирование размеров щели производитс  болтами 6, установленными не в самих секци х, а в П-образных постел х 7 дл  сопел. Крепление рабочих сухарей 8 сопел с внешней стороны корпуса позвол ет производить быструю смену сухарей.The upper and lower headers are assembled from the sections of the slotted nozzles 1 into one frame 2. The sections are fixed to each other, with the lid 3 and with the inlet stand 4 with the help of pins or cylindrical projections. The seal is created by ring gaskets and clamping screws 5. The adjustment of the size of the slit is made by bolts 6, which are not installed in the sections themselves, but in the U-shaped beds 7 for nozzles. The fastening of the working crackers 8 nozzles on the outside of the body allows for a quick change of crackers.

Устройство работает следующим образом.The device works as follows.

В паузах в работе гидросбива щели сопел закрыты, система заполнена водой (4-6 атм); при включении гидросбива вода высокого давлени  (100-150 атм) открывает щель 0,1-0,15 мм, образу  узкую направленную струю по всему фронту верхнего и нижнего коллекторов. При забивании щели отпускаетс  прижимной винт и замен етс  люба  секци  независимо от ее местоположени  в коллекторе .In the pauses in the operation of the water jet, the slit of the nozzles are closed, the system is filled with water (4-6 atm); when high-pressure water is turned on, high-pressure water (100-150 atm) opens a slit of 0.1-0.15 mm, forming a narrow directed jet along the entire front of the upper and lower collectors. When the gap is clogged, the clamping screw is released and any section is replaced, regardless of its location in the manifold.

Предмет изобретени Subject invention

Устройство дл  гидросбива окалины с прокатываемых заготовок, содержащее коллектор с секционными соплами, отличающеес  тем, что, с целью повышени  эффективности очистки , оно выполнено в виде рамы с П-образными поперечинами, в которых расположены секции сопел, и снабжено торцовыми винтами дл  поджати  секций.A device for descaling the rolled billet containing a collector with sectional nozzles, characterized in that, in order to increase the cleaning efficiency, it is made in the form of a frame with U-shaped crossbars in which the nozzle sections are located, and provided with end screws for pressing the sections.
