Channel 9 for supplying a liquid refrigerant has a check valve 16 and a throttle valve 17.

Предлагаемое устройство работает следующий образом.The proposed device works as follows.

Сухой лед, в виде, например. Заранее изготовленных цилиндрических брикетовj загружают в бункер 4. Включают расположенньй вне устройства на транспортном средстве единый привод (не показан), сообщающий через гибкий вал 15 и передаточный механизм 14 вращательное движение фрезе 6 и посредством конического колеса щетке 11. При подпружинивании осуществл етс подача сухого льда к фрезе 6, превращающей сухой лед в гранулы, подхватываемые поступающим через подвод щий пневмопривод 2 в смеситель- ную камеру 7 сжатым воздухом и направл емые им через выходной сопловой канал 8 в зону обработки. Чер,з дополнительньп канал 9 подводитс жидкий хладагент, который в смесительной камере образуетс в лед ные гранулы и охлаждает лед ные гранулы сухого льда, преп тству их оплавлению от нагрева, и совместно с последними через выходной сопловой канал 8 направл етс в рабочую зону.Dry ice, in the form, for example. Prefabricated cylindrical briquettes are loaded into the hopper 4. A single drive located outside the device on the vehicle (not shown) is switched on, which informs the rotary motion of the cutter 6 through the flexible shaft 15 and the transmission mechanism 14 and through the tapered wheel to the brush 11. When springing, dry ice to the milling cutter 6, which converts dry ice into granules, picked up by compressed air entering through the inlet pneumatic actuator 2 into the mixing chamber 7 and directed by it through the outlet nozzle channel 8 to treatment area. In addition to the channel 9, a liquid refrigerant is supplied, which in the mixing chamber forms into ice granules and cools the ice granules of dry ice, preventing their melting from heating, and, together with the latter, is directed through the outlet nozzle channel 8 into the working zone.

Возможен вариант подсоединени к дополнительному подвод щему каналу 9 коллектора, установленного на упом нутом транспортном средстве и подсоединенного, например, к водопроводной сети. Вода, проход через каплеобразующий распылитель 10 в смесительную камеру 7, образует лед ные гранулы под воздействием охлажденных паров сжиженного воздуха, сжиженного азота или подобным им хладагентам , поступающим в смесительную камеру в зависимости от оборудовани .A variant is possible to connect to an additional supply channel 9 of the collector installed on said vehicle and connected, for example, to a water supply network. The water passing through the droplet-forming sprayer 10 into the mixing chamber 7 forms ice granules under the influence of cooled liquefied air vapor, liquefied nitrogen or similar refrigerants entering the mixing chamber depending on the equipment.
