Изобретение относитс к переработке полимерных материалов и предназначено дл использовани в дисковых и черв чно-дисковых экструдерах в химической промышленности.The invention relates to the processing of polymeric materials and is intended for use in disk and worm-shaped disk extruders in the chemical industry.
Известна дискова головка дл полимерных материалов, содержаща корпус, неподвижный диск и подвижный диск, на котором смонтированы выступающее за его торцовую поверхность плунжеры, снабженные приводом вращени 1.A known disc head for polymeric materials, comprising a housing, a fixed disc and a movable disc, on which are mounted protruding beyond its end surface plungers, provided with a rotational drive 1.
Недостатком дисковой головки вл етс сложность ее конструкции, что обусловлено, наличием на подвижном диске вращающихс плунжеров.The drawback of a disk head is the complexity of its design, which is caused by the presence of rotating plungers on the movable disk.
Наиболее близкой по технической сущности и достигаемому результату - к изобретению вл етс дискова голоВ ка дл полимерных материалов, содержаща корпус, -подвижный и неподвижный диски, на обращенных друг к другу поверхност х которых выполнены выступы 2.The closest in technical essence and the achieved result - to the invention is a disc head for polymeric materials, comprising a body, a movable and a fixed disk, on the surfaces of which are facing each other which projections 2 are made.
Выступы на поверхност х дисков выполнены в виде изогнутых лопастей.The projections on the surfaces of the discs are made in the form of curved blades.
Недостатком дисковой головки вл етс то, что в ней невысока степень смешени и гомогенизации из-за исполь зовани только однородных деформацийThe disadvantage of a disk head is that it has a low degree of mixing and homogenization due to the use of only homogeneous deformations.
сдвига, имеющих место в зазоре между торцовыми поверхност ми дисков. При этом невозможен взаимный переход частиц расплава из одной области деформации в другую по рабочему зазору , а конструкци лопастей не позвол ет предотвратить попадание нерасплавленного , плохо гомогенизированного полимера в формующий элемент, shifts occurring in the gap between the face surfaces of the disks. At the same time, the mutual transfer of melt particles from one deformation region to another along the working gap is impossible, and the design of the blades does not allow preventing the ingress of unmelted, poorly homogenized polymer into the forming element,
10 что снижает качество изделий.10 which reduces the quality of products.
Цель изобретени - повышение качества .изделий за счет интенсификации процесса смешени и гомогениза15 ции расплава.The purpose of the invention is to improve the quality of the products due to the intensification of the process of mixing and homogenization of the melt.
Достигаетс указани цель тем, что в дисковой головке дл полимерных материалов, содержащей корпус, подвижный и неподвижный .диски, на об20 ращенных друг к другу поверхност х которых выполнены выступы, выступы на одном из дисков расположены по спирал м и выполнены с пазами дл прохода выступов другого диска, ко25 торые выполнены кольцевыми.The goal is achieved by the fact that in a disk head for polymeric materials, comprising a housing, a movable and stationary disks, on which surfaces, protrusions are made to each other, protrusions, protrusions on one of the disks are arranged in spirals and are made with grooves for passage another disk, which are made annular.
На фиг. 1 изображена дискова головка , продольный разрез; на фиг.2 узел I на фиг. 1; на фиг. 3 - вариант выполнени выступов с перепускHfciMH отверсти ми; на фиг. 4 - разрезFIG. 1 shows a disk head, a longitudinal section; in FIG. 2, node I in FIG. one; in fig. 3 shows an embodiment of the protrusions with by-pass HfciMH holes; in fig. 4 - section
