(54) ИЗМЕЛЬЧИТЕЛЬ МАТЕРИАЛОВ(54) MATERIAL GRINDER

II

Изобретение .относитс к измельчител м материалов,преимущественно водорослей.The invention relates to pulverized materials, mainly algae.

Известен измельчитель материалов, включающий , снабженный заборным и отвод щим патрубками цилиндрический корпус с размещенным в нем режущим аппаратом и насос 1 .A known material shredder includes, a cylindrical body provided with a suction and discharge nozzles with a cutting unit and a pump 1 therein.

Недостатком такого измельчител вл етс низкое качество измельчени водорослей , так как его режущий аппарат выполнен в виде ножей и часть водорослей, ориентированна в перекачиваемой воде параллельно режущей кромке ножей, не подвергаетс воздействию последних.The disadvantage of such a grinder is the poor quality of the algae grinding, since its cutting apparatus is made in the form of knives and a part of the algae, oriented in the pumped water parallel to the cutting edge of the knives, is not affected by the latter.

Наиболее близким по технической сущности к предлагаемому вл етс; измельчитель материалов, включающий корпус с заборным и отвод щим патрубками и два горизонтальных режущих элемента, соосно установленных друг в друге с возможностью вращени в разные стороны от механизмов привода 2. The closest in technical essence to the proposed is; a material shredder, comprising a housing with intake and discharge pipes and two horizontal cutting elements, coaxially mounted in each other with the possibility of rotation in different directions from the drive mechanisms 2.

Данный измельчитель, также как и первый , не обеспечивает качественное измельчение водорослей.This grinder, as well as the first, does not provide high-quality grinding of algae.

Цель изобретени - повышение качества измельчени .The purpose of the invention is to improve the quality of grinding.

Это достигаетс тем, что левые половины режущих элементов выполнены перфорированными , а в стенках их правых половин выполнены перепускные окна, причем измельчитель снабжен скребком, шарнирно подвешенным к корпусу над левой половиной внешнего режущего элемента и наклонно расположенным к его поверхности, и вертикальной кольцевой перегородкой, неподвижно закрепленной между левой и правой половинами внешнего режущего элемента, а заборный патрубок подсоединен к корпусу непосредственно над упом нутым скребком .This is achieved by the fact that the left halves of the cutting elements are perforated, and the bypass windows are made in the walls of their right halves, and the grinder is equipped with a scraper suspended pivotally to the body above the left half of the external cutting element and inclined to its surface, with a vertical annular partition fixed fixed between the left and right halves of the outer cutting member, and the intake manifold is connected to the housing directly above said scraper.

Кроме того, режущие элементы выполнены в виде цилиндрических барабанов, а механизмы привода выполнены в виде крыльчаток , размещенных соответственно в заборном и отвод щем патрубках, вал первой из которых подсоединен к внешнему режущему элементу, а вал второй - к внутреннему режущему элементу.In addition, the cutting elements are made in the form of cylindrical drums, and the drive mechanisms are made in the form of impellers placed respectively in the intake and discharge nozzles, the first shaft of which is connected to the external cutting element, and the second shaft to the internal cutting element.

Claims

FIG. I schematically shows the shredder of materials, mainly algae, side view, partial section; in fig. 2 - the same, top view; in fig. 3 is the same, section A-A in FIG. 1. The shredder includes a horizontal cylindrical body 1 with end caps, - equipped with a suction nozzle 2, a discharge nozzle 3 and cutting elements. The latter are made as coaxially mounted in each other rotating in different directions from the drive mechanisms of cylindrical drums 4 and 5, the left half of which are perforated, and their right half have flat walls with bypass windows 6. A scraper 7 is mounted between the case 1 and the outer drum 4 pivotally suspended from the body above the left half of the drum and obliquely located to its surface, and a vertical ring partition 8 fixedly mounted between the left and right halves of the outer drum a. The intake pipe 2 is connected to the housing directly above the scraper 7, and the discharge pipe 3 is in the location zone of the bypass windows 6, while the pipes are connected to main pipelines 9 through which the water with algae is pumped. One of the drums may be cut along the generatrix, elastically pressing against the other. The grinder, is supplied with the edges 10 and 11 providing the required rigidity of a design. The drive mechanisms of the drums 4 and 5 are made in the form of impellers of known construction, located respectively in the intake and outlet nozzles in the housing 12, with the shaft 13 of the first impeller connected to the outer drum 4 and the shaft 14 of the second impeller to the inner drum 5. During operation, the shredder Into the housing 1, a stream of water containing algae is fed and diverted, causing spinning of the algae in the holes in the perforated holes through the impellers and the shafts 13 and 14 in various directions. The first part of the drums, their cutting by the edges of the holes, the entry of crushed algae into the drum 5 and their subsequent withdrawal through the bypass windows of the 6 drums into the outlet nozzle 3. The algae deposited on the drum 4 surface are removed from it with simultaneous rubbing with a scraper 7, pressed to the drum with a stream of water pressing on it. Due to this implementation of the shredder, the quality of the algae grinding is significantly improved, and the cutting apparatus is also driven by the medium to be processed, which reduces the energy intensity of the grinding process. Claim 1. Grinder materials, mainly algae, comprising a housing with intake and discharge pipes and two horizontal cutting elements, coaxially installed in each other with the ability to rotate in different directions from drive mechanisms, characterized in that, in order to improve the quality of grinding, the left halves of the cutting elements are perforated, and bypass windows are made in the walls of their right halves, and the chopper is provided with a scraper pivotally pointed to the body above the left half in eschnego cutting element and positioned obliquely to its surface, and an annular vertical wall fixedly secured between the left and right halves vneschnego cutting member and the intake pipe is connected to the body directly above said scraper. 2. A shredder according to claim 1, characterized in that the cutting elements are in the form of cylindrical drums. 3. A shredder according to claim 1, characterized in that the drive mechanisms are made in the form of impellers placed respectively in the intake and discharge nozzles, the shaft of the first of which is connected to the outer cutting member, and the shaft of the second to the inner cutting member.
