Description

Изобретение относитс к химической промышленноеги и предназначено дл измельчени материалов, может также примен тьс в промышленности строитель ньк материалов и других отрасл . народ ного хоз йства. Известен измельчитель.содержащий бун , кер, корпус и дисковый рабочий орган LlJ. Такой измельчитель загр зн ет продукты помола, имеет большой уровень шума и вибрации и характеризуетс высокой энергоемкостью. Наиболее близким техническим решением к изобретению вл етс устройство дл тонкого измельчени , содержащее корпус с входным и выходным патрубками и эластичную рабочую камеру, между отсеками которой и корпусом образованы полости, соединенные трубопроводами с источником высокого гидростатического давлени 2. Недостаток устройства заключаетс в его низкой удельной производительности . Цель изобретени - повыш.ение удельной производительности устройства. Эта цель достигаетс тем, что в известном устройстве, содержащем корпус с входным и выходным патрубками и эластичную рабочую камору, между стенками которой и корпусом образованы полости , соединенные трубопроводами и источником высокого гидростатического давлени , рабоча камера вьтолнена из двух усеченных конусов, соединенных большими основани ми, причем угол наклона стенок рабочей камеры больше угла естественного откоса измельченного материала. Изобретение иллюстрируетс чертежом . Устройство Содержит корпус 1, внутри которого расположена эластична рабочй камера 2, выполненна из двух частей, имеющих форму усеченного конуса , сопр женньсх большими основани ми. Угол наклона стенок камеры выполненThe invention relates to the chemical industry and is intended for grinding materials, can also be used in the construction industry for construction of materials and other industries. national economic authority. Known shredder. Containing bun, Ker, housing and disk working body LlJ. Such a grinder contaminates grinding products, has a high level of noise and vibration, and is characterized by high energy intensity. The closest technical solution to the invention is a device for fine grinding, comprising a housing with inlet and outlet nozzles and an elastic working chamber, between the compartments of which and the housing are cavities connected by pipelines with a source of high hydrostatic pressure 2. The device has a low specific capacity . The purpose of the invention is to increase the specific performance of the device. This goal is achieved by the fact that in a known device comprising a housing with inlet and outlet nozzles and an elastic working chamber, between the walls of which and the housing there are cavities connected by pipelines and a source of high hydrostatic pressure, the working chamber is made of two truncated cones connected by large bases , moreover, the angle of inclination of the walls of the working chamber is greater than the angle of repose of the crushed material. The invention is illustrated in the drawing. The device comprises a body 1, inside of which an elastic working chamber 2 is located, is made of two parts, having the shape of a truncated cone, with large bases. The angle of the chamber walls is made

Claims

Claim

The device operates as follows. fifteen

Inside the working chamber 2, blocked by a lower shutter 9, the material subjected to grinding is loaded through the inlet pipe. Then close the inlet pipe with the upper shutter 8 and into the cavity 20 3 formed between the walls of the housing 1 and. chamber 2, through the fluid in the cavity, high pressure is supplied from the pressure source 5. The hydrostatic pressure in post 3 should exceed the compressive strength of the crushed material. When the material is compressed by pressure in excess of its compressive strength, the material is destroyed. thirty

After grinding the material, relieve pressure, open pipes 6.8 and the crushed material (in the form of powder)

A device for fine grinding, comprising a housing with inlet and outlet nozzles and an elastic working chamber, between the walls of which cavities are formed, connected by pipelines to a source of high hydrostatic pressure, characterized in that, in order to increase specific productivity, the working chamber is made of two truncated cones connected by large bases, and the angle of inclination of the walls of the working chamber is greater than the angle of repose of the crushed material.
