(54) КОНТАКТНАЯ СУШИЛКА ДЛЯ ДЛИННОМЕРНЫХ МАТЕРИАЛОВ(54) CONTACT DRYER FOR LONG-DIMENSIONAL MATERIALS

1one

Изобретение относитс к устройствам дл контактной сушки длинномерных материалов , в основном полимерных фильтровальных материалов в виде пленок толщиной 100150 мкм, имеющих оченьмалую механическую прочность, и может быть использовано на предпри ти х химической промышленности .The invention relates to devices for contact drying of long materials, mainly polymer filter materials in the form of films with a thickness of 100-150 microns, which have very low mechanical strength, and can be used in the chemical industry.

Наиболее близкой по технической сущности к предлагаемой вл етс контактна сушилка дл длинномерных материалов, содержаща камеру и размещенные в ней обогреваемый изнутри барабан, подающий, приемный, поддерживающие и нат жной ролики с транспортирующим полотном 1.The closest in technical essence to the present invention is a contact dryer for long materials, comprising a chamber and a drum heated inside it, feeding, receiving, supporting and tensioning rollers with a transporting web 1.

Недостатками известного устройства вл ютс наличие перекосов и плохое качество сущки.The disadvantages of the known device are the presence of distortions and the poor quality of the essence.

Цель изобретени - улучшение качества сушки путем исключени перекосов.The purpose of the invention is to improve the quality of drying by eliminating distortions.

Поставленна цель.достигаетс тем, что в камере дополнительно размещены бобины дл размотки и намотки высущиваемого материала , опирающиес через транспортирующее полотно на подающий и приемный ролики соответственно и установленные с возможностью осевого перемещени на наклонных направл ющих, прикрепленных к стенкам камеры.This goal is achieved by the fact that reels for unwinding and winding the dried material are additionally placed in the chamber, resting through the transporting web on the feed and receiving rollers, respectively, and axially mounted on inclined guides attached to the chamber walls.

На фиг. 1 изображена контактна сушилка дл длинномерных материалов, вид спереди; на фиг. 2 - то же, без передней крышки; на фиг. 3 - узел креплени нат жного ролика фиг. 4 - бобина размотки в увеличенном масштабе; на фиг. 5 - узел креплени наклонных направл ющих.FIG. 1 shows a contact dryer for long materials, front view; in fig. 2 - the same, without a front cover; in fig. 3 — the tension roller mounting unit of FIG. 4 - reel unwinding on an enlarged scale; in fig. 5 - an attachment unit for inclined guides.

Контактна сущилка дл длинномерных материалов содержит корпус 1, в котором установлен обогреваемый барабан 2, приводимый во вращение от привода 3 через систему шестерен 4. В корпусе 1 установлены подающий ролик 5, поддерживающие ролики 15 6, нат жной ролик 7 и приемный ролик 8, на которых расположено бесконечное транспортирующее полотно 9 из ткани,охватываю щее обогреваемый барабан 2.The contact bracket for long materials comprises a housing 1, in which a heated drum 2 is installed, rotated by the drive 3 through a gear system 4. The housing 1 has a feed roller 5, supporting rollers 15 6, a tension roller 7 and a receiving roller 8, on which is located an endless transporting cloth 9 of fabric, covering a heated drum 2.

Claims

The housing 1 houses a reel 10 for unwinding a long material and a reel 11 for winding a long material. The reels 10 and 11 are mounted with their ends on inclined guides 12 attached to the brackets 13, which are attached to the walls of the housing 1. The guides 12 have a bearing part 14, made in the form of a knife, and a stop projection 15 for the free movement of the reel in a horizontal plane. The tension roller 7 is made movable and, using flywheels 16, can be moved in a horizontal plane to tension the transporting web 9. The reel 10 under the force of gravity rests its forming on the feed roller 5 through the fabric of the endless transporting web 9. The reel 11 rests in the same way on the take-up roller 8. For a snug fit of the reels 10 and 11 to the transporting web 9 in the areas of the feed 5 and A5 and 8 small rollers, the angle of inclination of the guides 12 relative to the vertical should not exceed 60 °. To adjust the mutual position of the bobbins 10 and 11 and the rollers 5 and 8, respectively, the inclined guides 12 are rotatable relative to the axis 17 and provided with screws 18. Contact dryer. works as follows. A reel 10 with a roll of wet film is mounted on inclined guides 12, which are installed so as to ensure that the reel 10 fits snugly to the feed roller 5 through the transporting web 9. The reel 11 is also mounted in relation to the take-up roller 8. As the drum 2 rotates, the movement of the endless transporting web 9, which in turn drives the rollers 5-8 and through them the reels 10 and 11. When the transporting web 9 mixes relative to the drum 2 and relative to the rollers 5 and 8, it draws into it with Relocation (either right or left) of reels 10 and 11, and the film follows along with the web and the film is not displaced relative to it. The deformation of the film, distortions, and consequently the folds on it, are eliminated, the high quality of the film is ensured. As the diameter of the wet film roll decreases, the reel 10 under its own weight is evenly lowered along the inclined guides 12, all the while leaning on the transporting web and the take-up roller 5. As the diameter of the dried film increases, the reel 11 also moves along the inclined guides 12 only upwards, leaving being in constant contact with the transporting web 9 and through it with the roller 8. The proposed dryer for long materials will improve the quality of drying. Claim dryer for long materials containing a chamber and an internally heated drum supplying, receiving, supporting and tensioning rollers with a transporting web, characterized in that, in order to improve the quality of the essence by eliminating distortions, the chamber is additionally placed reels for unwinding and winding the material being dried, supported through the transporting web on the feed 1F (th and take-up rollers, respectively, and mounted with the possibility of axial movement. on clone guides attached to the walls of the chamber.
