Description
Изобретение относитс к фотографическим составам и подложкам дл них, а именно к устройствам дл плавлени фотографической эмульсии.The invention relates to photographic compositions and substrates for them, namely, devices for melting photographic emulsion.
Известны устройства дл плавлени фотюграфической эмульсии, содержащие обогреваемый элемент с бункером над ним и обогревающим элементом внутри системы подачи и отвода обогревающей жидкости и привод.Devices are known for melting a photographic emulsion containing a heated element with a hopper above it and a heating element inside the supply and removal system of the heating fluid and the drive.
С целью улучшени качества эмульсии путем непрерывности плавлени в предложенном устройстве, бункер выполнен с обогревающей рубашкой на его наружной поверхности и установлен с зазором, а обогреваемый элемент выполнен в виде цилиндра , установленного с возможностью вращени относительно обогревающего элемента , выполненного в виде полуцилиндра с отверсти ми на его поверхности, установленного .на трубе системы подачи жидкости; оно снабжено эластичным ножом дл удалени эмульсии с поверхности цилиндра.In order to improve the quality of the emulsion by continuity of melting in the proposed device, the hopper is made with a heating jacket on its outer surface and is installed with a gap, and the heated element is made in the form of a cylinder mounted rotatably relative to the heating element made in the form of a half-cylinder with holes its surface mounted. on the pipe of the fluid supply system; it is provided with an elastic knife to remove the emulsion from the surface of the cylinder.
На фиг. 1 показано устройство на фиг. 1; на фиг. 2 - вид по стрелке А на фиг. 1.FIG. 1 shows the device in FIG. one; in fig. 2 is a view along arrow A in FIG. one.
Устройство состоит из обогреваемого элемента в виде цилиндра 1 с обогревающим элементом в виде полуцилиндра 2 с отверсти ми 3 трубы 4, с отверсти ми 5, системы отвода жидкости трубы 6 с отверсти ми 7, системы подачи жидкости, бункера 8 с обогревающей рубашкой 9.The device consists of a heated element in the form of a cylinder 1 with a heating element in the form of a half cylinder 2 with openings 3 pipes 4, with openings 5, a system for draining the liquid of pipe 6 with openings 7, a liquid supply system, a hopper 8 with a heating jacket 9.
Устройство работает следующим образом .The device works as follows.
Застудененна фотографическа эмульси помещаетс в бункер 5, а в цилиндр /, установленный в станинах 10 и 11 и вращающийс от электропривода 12, подаетс обогревающа жидкость, котора по трубе The frozen photographic emulsion is placed in the hopper 5, and a heating fluid, which is fed through a pipe, is fed into the cylinder (10) and (11) installed in the beds 10 and 11 and rotated from the electric actuator 12.
0 6 через щелевые отверсти 7 поступает в полость полуцилиндра 2, заполнив его объем , вытекает через отверсти 5 на внешнюю поверхность полуцилиндра 2 и, омыва цилиндр /, нагревает его. Рассто ние между 0 6 through the slit holes 7 enters the cavity of the half-cylinder 2, filling its volume, flows out through the holes 5 onto the outer surface of the half-cylinder 2 and, washing the cylinder /, heats it. Distance between

Обогревающа жидкость из полости цилиндра 1 удал етс через отверсти 5 трубы 4.5, the inner surface of the cylinder / and the outer surface of the half-cylinder 2 is selected on the basis of the most complete heat release by the heating fluid. The heating fluid from the cavity of the cylinder 1 is removed through the openings 5 of the pipe 4.
Фотографическа эмульси , расплавл сь у наружной поверхности бункера 8, стекает вниз и попадает на цилиндр /, поверхность которого служит дном бункераThe photographic emulsion, melted at the outer surface of the bunker 8, flows down and falls on the cylinder /, the surface of which serves as the bottom of the bunker

на ней происходит плавление нижнего сло фотографической эмульсии. Вследствие вращени цилиндра 1 и наличи зазора между его плоскостью и кромками бункера 8 расплавленна фотографическа melting of the lower layer of the photographic emulsion occurs on it. Due to the rotation of the cylinder 1 and the presence of a gap between its plane and the edges of the bunker 8, the melted photographic

и снимаетс эластичным ножом 13, а затем через обогреваемое приспособление 14 отводитс на дальнейшую обработку. Цилиндр / нри вращении очищаетс от несн той ножом 13 фотографической эмульсии приспособлением 15, помещенным в ванну 16 и омываемым раствором, который подаетс в ванну /5 через патрубок 17. Отработанный раствор отводитс через патрубок 18.,and removed with an elastic knife 13, and then through a heated device 14 is retracted for further processing. The cylinder / rotation is cleared by a knife 13 of a photographic emulsion with a device 15 placed in a bath 16 and washed with a solution that is fed into the bath / 5 through a pipe 17. The spent solution is discharged through a pipe 18.
В устройстве происходит интенсивное плавление фотографической эмульсии в зазоре между бункером 8 и цилиндром 1, а также на наружной поверхности бункера 8, поэтому брем плавлени фотографической эмульси1и уменьщаетс , а производительность повышаетс .The device intensively melts the photographic emulsion in the gap between the hopper 8 and the cylinder 1, as well as on the outer surface of the bunker 8, therefore the melting burden of the photographic emulsion decreases, and the productivity increases.
