(54) СТАТИЧЕСКИЙ СМЕСИТЕЛЬ(54) STATIC MIXER

Изобретение касаетс смесителей неподвижных элементов, располагаемых в каналах, провод щих текучую среду, и может, например, использоватьс на меииинах производств химических волокон.The invention relates to fixed-element mixers disposed in fluid-conducting channels and, for example, can be used in chemical fiber production industries.

Известен статический смеситель, выполненный в виде нескольких установленных в канале последовательно один за другим смесительных элементов . Каждый смесительный элемент имеет сложную геометрическую поверхность: она выполнена винтовой и образована из пластинки пр моугольной формы, короткие стороны котсфой повернуты относительно ДРУг друга на 180 1 .Known static mixer, made in the form of several installed in the channel sequentially one after the other mixing elements. Each mixing element has a complex geometric surface: it is made of a screw and is formed of a rectangular plate, the short sides are turned with respect to each other by 180 1.

Недостаток данного смесител низка степень перемешивани жидкости . The disadvantage of this mixer is the low degree of mixing of the liquid.

Известен проточный смеситель статического типа, содержащий камеру смешени и установленные один за другим неподвижные смесительные элементы , образующие канал сложной формы , рабоча поверхность которых сопр жена с поверхностью стенок камеры и расположена под углом к оси канала 2 .A static type flow mixer is known, containing a mixing chamber and fixed one after another stationary mixing elements forming a channel of complex shape, the working surface of which is associated with the surface of the chamber walls and is angled to the axis of channel 2.

Недостатком этого смесител также вл етс низка степень перемешивани жидкости.The disadvantage of this mixer is also the low degree of mixing of the liquid.

С целью интенсификации процесса смешени путем многократного разделени и сли ни потока, смесительные элементы выполнены в виде пластин элиптической формы с прорез ми, расположенными вдоль большой оси сим0 метрии, и снабжены козырьками, укрепленными по периметру прорезей в диаметрально противопложном направлении на нижней и верхней поверхност х пластины. Дл предотвращени смешени In order to intensify the mixing process by multiple separation and flow confluence, the mixing elements are made in the form of plates of elliptical shape with slots along the major axis of symmetry, and are fitted with visors that are fixed along the perimeter of the slots in the diametrically opposite direction on the lower and upper surfaces plates. To prevent mixing

5 смесительных элементов кромка козырька выполнена с пазами.5 mixing elements the edge of the visor is made with grooves.

Смесительные элементы выполнены в виде пластин 1 эллиптической формы, которые устанавливаютс в корпусе 2 одна за другой, образу канал сложной форг1«4, и своей боковой поверх5 ностью контактируют с поверхностью корпуса. Вдоль большой оси симметрии пластины выполнены с прорез ми 3 и снабжены козырьками 4, укрепленными по периметру прорезей в диаметральноThe mixing elements are made in the form of plates 1 of elliptical shape, which are installed in the housing 2 one by one, forming a channel with a complex forg1, 4, and their side surface contact with the surface of the housing. Along the major axis of symmetry, the plates are made with slots 3 and are equipped with peaks 4, reinforced along the perimeter of the slots in diametrically

Claims

0 opposite direction on the lower and upper surface of the plates. The edge of the visor 4 is made with a pair of 5, to adhere adjacent elements. During installation, each subsequent mixing element is installed with rotation around the channel axis by 90 relative to the previous one. The mixer works as follows. The flow of fluid, moving into the channel and meeting the first mixing element in its path, is divided by the edge of the visor into three flows. One of them passes in the cavity of the visor 4, and the other two pass in space on one and the other side of the visor. The first stream, which passes through the cavity of the visor, goes to the other side of the plate, when uhm, it expands and with further movement it is separated by a visor placed on this side of the plate into two streams. The flows, which pass through the gap between the visors and the surface of the channel, rise along the inclined surface of the plate and, draining from one stream, pass through the cavity of the visor located on the other side of the plate. Claim 1. A static mixer containing a mixing chamber and one after another inclined fixed mixing elements that form a channel of complex shape, the working surface of which is associated with the surface of the chamber walls, which is made in order to intensify the mixing process by repeated separation and merging of the flow, mixing elements. made in the form of plates of elliptical shape with slots along the major axis of symmetry, and equipped with visors, reinforced around the perimet The grooves are diametrically opposite to the lower and upper surfaces of the plate. 2. The static mixer according to claim 1, characterized in that, in order to prevent mixing of the mixing elements, the edge of the visor is grooved.
