(54) МОЛОТКОВАЯ ДЮБИЛКА(54) HAMMER BLANKER

II

Изобретение относитс к молотковым дробилкам , используемым в сельскохоз йственном производстве .This invention relates to hammer mills used in agricultural production.

Известны молотковые дробилки, включающие дробильную камеру, вентил тор, циклон и цилиндрический фильтр, соединенные между собой 5 посредством трубопроводов 1 и (2.Hammer crushers are known, including a crushing chamber, a fan, a cyclone and a cylindrical filter interconnected 5 through pipelines 1 and (2.

Однако такие дробилки имеют низкую зффективность работы и недостаточную эксплуатационную надежность, так как в них не обеспечиваетс непрерывна очистка фильтра в процессе О работы.However, such crushers have low efficiency and lack of operational reliability, since they do not ensure continuous cleaning of the filter in process O of work.

Цель изобретени - повышение эффективности работы дробилки и ее эксплуатационной надежности путем обеспечени непрерывной очистки фильтра.The purpose of the invention is to increase the efficiency of the crusher and its operational reliability by ensuring continuous filter cleaning.

Это достигаетс тем, что фильтр снабжен прикрепленными друг к другу чистиком и ло пастным колесом, свободно установленными внутри него на трубопроводе, соедин ющем между собой вентил тор и циклон, причем входное отверстие фильтра расположено тангенциально относительно его корпуса.This is achieved by having the filter attached to each other by a scraper and a pasta wheel that are freely installed inside it on the pipeline connecting the fan and the cyclone, with the inlet of the filter tangentially relative to its body.

На фиг. 1 схематично изображена молоткова дробилка, общий вид; на фиг. 2 - ф(|1льтр, продольный разрез.FIG. 1 schematically shows hammer crusher, general view; in fig. 2 - f (| 1ltr, longitudinal section.

Дробилка включает дробильную камеру 1, внутри которой установлены молотковый ротор 2, решето 3 и деки 4. На корпусе дробильной камеры закреплен бункер 5, а на валу ротора 2 установлен вентил тор 6, который нагнетательным трубопроводом 7 соединен с циклоном 8. Выходной патрубок 9 циклона соединен посредством трубопровода 10 с цнлиндрическим фильтром П. Последний закреплен На нагнетательном трубопроводе 7 и трубстроводом 12 св зан с дро&шьной камерой 1. Ш|утри фильтра 11 расположен чистик 13, шлполненный в виде вертикальной рамки с щетками, контактирующими с поверхностью фильтра. %iCTiac 13 св зан с лопастным колесом 14, свободно установленным на нагнетательном трубо овове 7 непосредственно у входного отерет 15, тангенциально расположенного относше ыю корпуса фильтра 11.The crusher includes a crushing chamber 1, inside which a hammer rotor 2, a sieve 3 and deck 4 are installed. A hopper 5 is fixed to the crushing chamber case, and a fan 6 is installed on the rotor shaft 2, which is connected to the cyclone 8 by the discharge pipe 7 of the cyclone connected by pipeline 10 with a cylindrical filter P. The latter is fixed on the discharge pipe 7 and pipe 12 is connected to the nucleus & amphibious chamber 1. The spike 13 of the filter 11 houses the scraper 13, filled with a vertical frame with brushes, pin Editin from the filter surface. % iCTiac 13 is associated with a paddle wheel 14, freely mounted on the discharge pipe 7 directly at the inlet wipe 15, which is tangentially located relative to the filter housing 11.

Claims

The crusher works in the following way. 3 The material from the hopper 5 enters the crushing chamber 1, where it is crushed by the rotor 2 and decks 4. The crushed material through the sieve 3 is fed by the fan 6 into the cyclone 8. The air separated from the material, with dust, is fed into the filter 11 with dust. in the filter, the air flow acts on the impeller 14 and causes it to rotate. At the same time, the wheel 13, the wheel 13, which is associated with the blade wheel, begins to rotate, carrying out the cleaning of the inner surface of the filter. Part of the purified air is vented to the atmosphere, and the axial air flow with dust returns to the crusher through pipeline 12. Thanks to this crusher, the filter is constantly cleaned, which significantly improves the efficiency of the crusher and its operational reliability. The invention includes a hammer mill, a crushing chamber, a fan, a cyclone and a cylindrical filter interconnected through pipelines, characterized in that, in order to improve the efficiency of the crusher and its operational reliability, continuous cleaning of the filter is provided, the latter are fitted with attached to a friend with a scraper and a paddle wheel, freely installed inside it on the pipeline connecting the fan and the cyclone, the inlet of the filter being located tangentially relative to its body.
