Definitions
- the present invention relates to a particle jet nozzle for generating a particle beam, for example for Removing rust spots on metal parts can be used can.
- the particle jet nozzle has one Nozzle body with an outlet and a suction port has.
- An acceleration pipe is also provided, that runs at least partially inside the nozzle body, the front end of the acceleration tube in Area of the outlet opening is arranged and the rear end of the acceleration tube has a further suction connection.
- the suction connection of the nozzle body with a vacuum source for example a commercially available bucket vacuum
- the further suction connection of the acceleration pipe is connected to a particle reservoir in order to to suck up and accelerate the jet particles.
- the particle jet nozzle according to the invention is very simple and has the great advantage that it can be used with commercially available Suction devices, e.g. Wet vacuum cleaners, industrial vacuum cleaners or bucket suction can be operated.
- Suction devices e.g. Wet vacuum cleaners, industrial vacuum cleaners or bucket suction can be operated.
- Particle jet nozzle can rust spots completely remove, using the suction device required as a vacuum source is present in almost every household. So leave rust spots on vehicle bodies or the like easy and complete removal without any Workshop must be visited.
- the acceleration tube is also led out of the nozzle body and has an air intake opening outside the nozzle body on.
- the particulate material is sucked through the accelerator tube.
- it takes place through the air through the Air intake has been sucked in, additional acceleration of the particle material within the acceleration tube. This means that even with low suction power or a longer path between the further suction connection and the particle reservoir have an excellent blasting effect produce.
- the air intake opening, the front end of the acceleration tube, and the intermediate portion of the acceleration tube lie on a straight line to avoid loss of friction or momentum. This creates a linear acceleration path achieved that the beam particles on a accelerated the highest possible speed.
- the front end of the acceleration tube is also located inside the nozzle body and is from the outlet opening only slightly spaced. This creates an additional acceleration effect achieved since between the end of the accelerator tube and the nozzle body formed a constriction is.
- the acceleration tube formed angled outside the nozzle body, the air intake opening in the area of the bend is arranged.
- the nozzle body of the particle jet nozzle can be angled be and have recessed grips on the outside. This makes handling the particle jet nozzle easier.
- the length of the acceleration tube can be changed.
- the acceleration tube can be made in several parts be opposite, with part of the acceleration tube another part is movable.
- the impact effect can be determined by the length of the acceleration tube change the particle material so that the particle jet nozzle on different materials or different Impact objects can be set.
- the nozzle body is in the area the outlet opening has a rubber-like material since hereby the particle jet nozzle sealing against the impact object can be put on and possible damage excluded are.
- the first suction connection designed as a plug connection for a conventional vacuum cleaner is. This allows the particle jet nozzle according to the invention as an additional part for a conventional vacuum cleaner use the suction hose only in the plug connection must be inserted.
- the figure shows a cross-sectional view through a particle jet nozzle according to the invention, on an impact object is put on.
- the particle jet nozzle shown in the figure consists of a Nozzle body 10, which has an outlet opening 12 and a Has suction connection 14.
- the nozzle body 10 consists of a Plastic tube 16, which is at an angle of approximately 135 ° is angled and in its angled area Grip part 18 forms, on the outside of which recesses 20 are provided are.
- the front area of the nozzle body is through a rubber cap 22 formed, which is placed on the tube 16 and itself tapered towards the outlet opening 12.
- the suction connection 14 of the nozzle body 10 is at the end of the handle part 18 the nozzle body arranged and as a plug connection for the Suction hose 24 of a conventional bucket suction device is formed.
- a nozzle 26 integrally formed, which has a bore in which a Accelerator tube 30 is received, the front end 32 is arranged in the region of the outlet opening 12 and its rear end 34 has another suction port 36.
- the front end 32 of the acceleration tube 30 is inside of the nozzle body 10 and from the outlet opening 12 only slightly spaced so that there is between the front End 32 of the acceleration tube 30 and the inner jacket wall the rubber cap 22 results in an annular space 38.
- a plastic hose 44 plugged in to a not shown Particle reservoir, such as a sand container is.
- the rear end 34 of the acceleration tube 30 is shown in the Embodiment formed by an L-piece 40, which has an air intake opening in the form of a bore 42.
- the air intake opening 42 is concentric with the front one Outlet end 32 of acceleration tube 30 formed, i.e. the front end 32, the bore 42 and the intermediate section of the acceleration tube 30 lie on a straight line.
- the bore 42 is in the region of the Bending the L-piece of the acceleration tube 30 arranged and the acceleration tube 30 runs on the bore 42 in a straight line up to its front end 32.
- the Hose 24 of a conventional bucket suction device into the plug connection 14 of the nozzle body 10 inserted. Furthermore, the Hose 44 in the particle reservoir, for example one plastic container filled with quartz sand. To Placing the nozzle body 10 on an impact object A and after the vacuum cleaner has been started up, it is created within of the nozzle body 10 a negative pressure, which the jet particles sucks via the hose 44 and the acceleration tube 30.
- nozzle body 10 in the area of its contact surface on the Impact object A made of a rubber-elastic material is tight against the object and damaged this not.
- To target areas of the impact object To be able to treat a certain size can also be based on the Impact object A placed a template (not shown) made of rubber, for example, and which has openings of different sizes. hereby the beam area can be determined, the larger or can also be smaller than the outlet opening 12. simultaneously a good seal is always guaranteed, since both the Template as well as the jet head made of a rubber-like material consist.
- blasting material While the present invention has been related to sand described as blasting material. However, it is for the skilled person It is clear that other blasting materials are used in addition to sand can find.
