Description

Изобретение относится к измельчению пород и материалов, а именно к измельчителям вибрационного действия, и может быть использовано в лабо-_ раторной практике подготовки проб для физико-химических анализов.The invention relates to the grinding of rocks and materials, in particular to shredders of vibrational action, and can be used in laboratory practice of sample preparation for physico-chemical analyzes.

Известен измельчитель, содержащий вибростол, прижимное устройства и вертикально смонтированные между ними помольные стаканы, в которых свободно ¹размещены размольные органы в виде штоковГ1].Known chopper containing vibrating table, clamping device and vertically mounted between them grinding cups, in which freely ¹ are placed grinding bodies in the form of rods G1].

Наиболее близким к предлагаемому по технической сущности и достигав- 15 мому результату является измельчитель, содержащий вибростол, прижимное устройство и вертикально смонтированные между ними помольные стаканы, в которых свободно размещены размоль- 20 ные органы в виде штоков со сквозными продольными отверсгиямиСг].The closest to the proposed technical essence and achieved result is a grinder containing a vibrating table, a clamping device and grinding cups vertically mounted between them, in which grinding bodies are freely placed in the form of rods with through longitudinal openings Cr].

Недостаток известных измельчителей - низкая производительность процесса и обслуживания, что обусловле- 25 но низкой интенсивностью циркуляции материала и забиванием многочисленных углублений и каналов.A disadvantage of the known shredders is the low productivity of the process and maintenance, which is due to the low intensity of circulation of the material and clogging of numerous recesses and channels.

Цель изобретения - повышение производительности измельчителя. 30The purpose of the invention is to increase the performance of the grinder. thirty

Достигается это тем, что в измельчителе, содержащем вибростол, прижимное устройство и вертикально смонтированные между ними помольные стаканы, в которых свободно размещены размольные органы в виде штоков со сквозными продольными отверстиями, последние в штоках выполнены конически сужающимися, вниз.This is achieved by the fact that in a grinder containing a vibrating table, a clamping device and grinding cups vertically mounted between them, in which grinding bodies are freely placed in the form of rods with through longitudinal holes, the latter in the rods are made conically tapering downward.

При этом измельчитель снабжен дополнительными размольными органами в виде дисков, расположенных в стаканах под штоками.In this case, the grinder is equipped with additional grinding bodies in the form of disks located in glasses under the rods.

На чертеже изображена конструктивная схема предлагаемого измельчителя .The drawing shows a structural diagram of the proposed chopper.

На вибростоле 1 зафиксированы помольные стаканы 2, в которых свободно размещены размольные органы в виде дисков 3 и уложенных на них штоков 4 со сквозными конически сужающимися вниз отверстиями 5. Стаканы закрыты крышками 6 и прикреплены к столу прижимньии устройством 7.Grinding cups 2 are fixed on the vibrating table 1, in which grinding bodies are freely placed in the form of discs 3 and rods 4 laid on them with through holes conically tapering downward 5. The glasses are closed by covers 6 and attached to the table by pressing device 7.

В процессе работы измельчителя за счет генерируемой вибровоэбудителем вибрации порция засыпанного в стакан материала измельчается между размольными органами,, а также между диском и дном стакана. Одновременно материал циркулирует между поверхностями этих элементов. По окончании ι цикла продукт размола собирается в основном в отверстии каждого штока.During the operation of the grinder, due to the vibration generated by the vibrator, a portion of the material poured into the glass is crushed between the grinding organs, and also between the disk and the bottom of the glass. At the same time, the material circulates between the surfaces of these elements. At the end of the ι cycle, the grinding product is collected mainly in the hole of each rod.

Выгрузка продукта и очистка размольных органов ускоряются и облегчаются благодаря простоте форм последних. Процесс интенсифицирован за счет увеличения площади контактных рабочих поверхностей. Эти факторы повывают производительность измельчителя.Product unloading and cleaning of grinding organs are accelerated and facilitated by the simplicity of the forms of the latter. The process is intensified by increasing the area of contact work surfaces. These factors affect the chopper performance.

Claims

The invention relates to the grinding of rocks and materials, namely to shredders of vibratory action, and can be used in laboratory practice of preparing samples for physico-chemical analyzes. The known grinder containing a vibrating table, a pressing device, and grinding glasses vertically mounted between them, in which grinding bodies in the form of G1 rods are freely placed. The closest to the proposed technical essence and the achieved result is a grinder containing a vibrating table, a clamping device and grinding cups vertically mounted between them, in which the grinding bodies in the form of rods with through longitudinal branches of the PSC are freely placed. A disadvantage of the known grinders is low productivity of the process and maintenance, which is due to the low intensity of the circulation of the material and the clogging of numerous cavities and channels. The purpose of the invention is to increase the productivity of the grinder. This is achieved by the fact that the shredder, the vibrating table, the clamping device and the grinding cups vertically mounted between them, in which the grinding bodies are freely rotated in the form of rods with through longitudinal holes, are conically tapering downwards. At the same time, the grinder is equipped with additional grinding parts in the form of discs located in glasses with stem. The drawing shows the structural scheme of the proposed grinder. grinding table 2 is fixed on the vibrating table 1, in which grinding bodies in the form of disks 3 and rods 4 laid on them with through holes 5 that are conically tapering downwards are freely placed. The glasses are closed with covers 6 and are attached to the table by the device 7. the vibration generated by the exciter a portion of the material poured into the glass is crushed between the grinding organs and between. disc and bottom of the glass. At the same time, the material circulates between the surface tatm of these elements. At the end of the cycle, the grinding product is collected mainly in the hole in each stem, the product unloading and cleaning of the grinding bodies is accelerated and facilitated by the simplicity of the molds of the latter. The process is intensified by increasing the area of the contact working surfaces. These factors improve the performance of the crusher. Claim 1. Grinder containing a vibrating table, a pressure device and vertical humorous glasses mounted vertically between them, in which grinding bodies in the form of rods with through longitudinal openings are freely placed, in order to increase its productivity, the holes in the rods are made conically tapering down. 2. The shredder of claim 1, wherein it is equipped with additional grinding organs in the form of discs located in glasses under the rods. Sources of information taken into account in the examination 1.
