The described and illustrated treatment nozzles are exemplary embodiments which are indicative of direction for smaller or larger spatial forms.

With the invention according to the main and additional application also creates the possibility that aggregate or dopants can be added to the mixture of dry ice and compressed air. These include binders for setting dust, oils and fats, synthetic solvents, aggressive inorganic and organic cleaning agents and liquids such as alcohols, gasolines, surfactants, finely divided solids such as sands, stones, glass and metal particles, carbonates such as sodium bicarbonates, fire extinguishing agents u. etc. ..

The invention also includes a method of treating surfaces of inorganic and organic articles. Thereafter, inhomogeneous in the room form dry ice, which is provided for example granular, pellet and or rod-shaped with a length of up to 150 mm and a diameter of up to 3 mm, fed to a funnel-shaped feeder with vibrator. The amount of dry ice depends according to the capacity of the processing machine. According to one embodiment of the invention, the capacity of the funnel-shaped charging device is designed to be 0.3 to 1.5 kg. The inhomogeneous dry ice is broken down or ground in a first process step from a rotating in the operating state metering roller in one cycle to an average grain size of a maximum of 3 mm, so that in the space form substantially homogeneous intermediate product of pre-shredded dry ice is provided. The pre-shredded dry ice is comminuted in a second process step in a grinder consisting of two counter-rotating knurled crushing rollers by appropriate adjustment of the roll gap to the required particle size for surface treatment and in a third process stage with a suitable application for the treatment using the applied Compressed air is sprayed onto the surface of the material to be treated. The compressed air is introduced at a pressure of 0.05 to 10 bar in the metering device to the pre-shredded dry ice, which is taken up by the recesses arranged in the shell and transported by the rotation of the metering, using the compressed air from the wells in to blow one operation and feed the crushing rollers of the crushing device. The dry ice throughput ranges from at least 1.5 kg / h to 90 kg / h in a rotation range of the crushing rollers from 4 to 820 rpm.

As from the description of the treatment nozzles preferably to be considered 141 . 148 and 155 As can be seen, the nozzles listed are basically suitable for cleaning different objects, because the throughput can be made variable according to the particle size of the mixture of crushed dry ice and the adjustment of the compressed air. As a result, the treatment nozzles are suitable 141 . 148 and 155 for dry ice in fine grain texture. When using coarse-grained dry ice, which is obtained when setting the roll gap of about 2 mm to about 3 mm, only treatment nozzles with corresponding outlet openings of more than 3 mm can be used. If the treatment process is carried out with a grain size of> 3 mm, this is in any case a complete opening of the roll gap and thus a deactivation of the existing of counter-rotating crushing crushing device connected.

Treatment nozzles with a circular outlet cross section, which are referred to in the jargon as round nozzles, produce a uniform, not too aggressive circular cleaning surface on the surface to be irradiated of the material to be treated, the intensity with a greater distance to the irradiation surface smaller but the cleaning surface is larger.

Treatment nozzles with rectangular Aufstrahlquerschnitt, referred to in the jargon as flat nozzles, produce due to the transition region, which is also referred to in the jargon as a loft or survey, adapted to the dimension of the outlet opening, compared to the surface treatment with a round nozzle much more aggressive spray surface the surface of the material to be treated. Therefore, the flat nozzles used in the invention are particularly suitable for cutting flat products such as paper, cardboard and u. Like. And for abrasive removal particularly difficult to remove surfaces on different objects.

The round and flat nozzles can be used according to the invention in a compressed air range of 0.05 to 10 bar and overlying. Fine-grained dry ice with a grain size of approx.> = 0.1 mm to approx. 1.0 mm can be blasted onto the treatment surface with compressed air in the lower pressure range of up to 6 bar. Coarse-grained and unground dry ice with a grain size of more than 3 mm can not be effectively blasted onto the treatment surface at low pressures, or only to a limited extent from 2.5 bar. It should be noted that unground dry ice with a grain size of about 3 mm can only be transported to the treatment area with a pressure of about 2.5 bar via a treatment nozzle with an outlet cross-section or diameter of at least 3.5 mm. But this is an extremely high compressed air consumption of about 430 l / min. connected. The dry ice processing machine according to the main and additional application according to the invention therefore differs from the prior art dry ice irradiation devices by a much lower energy and compressed air consumption as well as much lower noise development.

According to one embodiment of the invention, the treatment nozzle designed as a flat nozzle for gentle cleaning of sooty printed circuit boards, the dry ice with a particle size of <= 2 mm with the aid of compressed air under 0.2 bar on this object at a dry ice consumption of 50 g / min., d. H. about 3 kg / h, can be inflated. The compressed air consumption is approx. 50 l / min ..

According to a further embodiment of the invention, the treatment nozzle designed as a flat nozzle is suitable for removing labels, the compressed air being set to 1.5 bar. The consumption of dry ice is 10 kg / h and The compressed air consumption at approx. 150 l / min. This means that even a foam can be cut and cut. In this case, for example, the method with a compressed air from 1 bar and a dry ice of 8 kg / h for clean cutting through a 20 mm thick plastic plate can be used. By increasing the compressed air to 4 bar and the dry ice to 25 kg / h, the separation process is accelerated. Here, a foam plate of 100 mm thickness can be easily cut through. The cutting or shaping of foam can also be realized in this way.

The cutting of plastics according to the teaching of the invention works fine with fine-grained dry ice at compressed air settings between 1 and 4 bar and a dry ice consumption of up to 35 kg / h. The procedure with regard to the setting of the grain size of the dry ice, the air pressure and the spatial shape of the treatment nozzles can be varied depending on the Nutzanwendung within wide parameter ranges.

The processing machine according to the invention can also be successfully used large amounts of dry ice of more than 100 kg / h with compressed air quantities of more than 3000 l / min using massively enlarged in the spatial form treatment nozzles with correspondingly enlarged outlet cross-sections. The suitable field of application includes the cleaning of large areas of space, for example, in factory buildings, hospitals, train stations, warehouses, aircraft and exhibition halls and the deicing of aircraft, especially the wings, railway cars and motor vehicles.

Since the process parameters, concerning the grain size of the dry ice and the working pressure of the compressed air, independently of each other and in terms of amount from a minimum to a maximum value are adjustable, for example, the process can be operated under minimum pressure and with maximum Trockeneismengen or under maximum pressure and minimal Trockeneismengen become. The modular system of the inventive processing machine for dry ice therefore allows a homogeneous dry ice throughput from 2 kg / h. In addition, the invention provides at a minimum working pressure of, for example, 0.05 bar, the production of a dry ice with a smallest possible grain size of 0.1 mm, so that the material to be treated can be effectively irradiated.

The mixture of crushed dry ice and compressed air can be enriched according to the teachings of the invention optionally with physically, chemically, biochemically, biologically and / or medically acting aggregate or dopants and nanoparticles to achieve special effects.

With the processing machine according to the invention in conjunction with the constructive and procedural and use engineering developments according to the additional application a wide range for different applications is developed.

The atomizing system according to the invention makes use of the substance mixture which has been adapted to the respective intended use, consisting of the comminuted dry ice 2 and the gaseous, pressurized transport medium from compressed air, surprisingly an effective surface treatment of various inorganic and organic articles. According to the teachings of the invention, these mixtures of substances can optionally be enriched with physical, chemical, biochemical, biological and / or medically active additives or dopants and nanoparticles for achieving particular effects.

The invention allows a variable adjustment of the process parameters, so that successful surface treatments of different treatment objects are achieved with low energy and compressed air consumption.
