Abstract
Изобретение относится к способу вихревого измельчения материала и устройству для его осуществления. Сущность способа измельчения заключается в том, что в помольной камере измельчаемый материал подвергается воздействию струй энергоносителя, который подается под углом к соответствующему радиусу зоны измельчения помольной камеры с образованием высокоскоростного вихря диспергируемого материала, а в объеме вихря создают локальные концентрации акустической энергии путем предпочтительного создания в группе струй энергоносителя пульсаций с частотой, не равной частоте пульсации в других струях, а ввод струй с различной частотой пульсации осуществляется в чередующейся последовательности. Особенность газодинамического устройства заключается в том, что в боковой стенке его помольной камеры установлены газоструйные излучатели высокого давления, излучающие каналы которых расположены под углом 60-85° к соответствующему радиусу помольной камеры, причем каждый газоструйный излучатель может быть выполнен в виде сопла и резонатора с возможностью настройки на различные резонансные частоты. В одном из вариантов исполнения каждый газоструйный излучатель высокого давления выполнен из двух блоков: соплового и резонаторного, между которыми расположен выходной излучающий канал в виде щели, дно которой является отражателем. В другом варианте исполнения ряд сопел пневматически связан между собой и каналом подачи энергоносителя посредством коллекторного канала, а резонаторы расположены в ряд напротив сопел, причем предпочтительно, чтобы резонансные частоты в каждом резонаторе или группе резонаторов были различны.The invention relates to a method of grinding the material and a vortex grinding device for its implementation. The essence of the grinding method is that the grinding material in the grinding chamber is exposed to jets of energy, which is fed at an angle to the corresponding grinding zone of the grinding chamber with the formation of a high-speed vortex of the material being dispersed, and local concentrations of acoustic energy are created in the vortex volume by preferably creating in the group jets of pulsation energy carrier with a frequency not equal to the pulsation frequency in other jets, and the introduction of jets with different pulsation frequency and carried out in alternating order. A feature of the gas-dynamic device is that high-pressure gas jet emitters are installed in the side wall of its grinding chamber, the radiating channels of which are located at an angle of 60-85 ° to the corresponding radius of the grinding chamber, each gas jet emitter can be made in the form of a nozzle and a resonator settings for different resonant frequencies. In one embodiment, each high-pressure gas jet emitter is made of two blocks: a nozzle and a resonator, between which there is an output radiating channel in the form of a slit, the bottom of which is a reflector. In another embodiment, a number of nozzles are pneumatically connected to each other and an energy carrier supply channel via a collector channel, and the resonators are arranged in a row opposite the nozzles, and it is preferable that the resonant frequencies in each resonator or group of resonators are different.
