Definitions
- Apparatus for conveying blasting medium in particular ice, ice pellets, ice snow or water-soluble
- the invention relates to a device for conveying a blasting medium, in particular of ice, ice pellets, ice snow or water-soluble blasting agent, with
- the invention relates to a novel transport system for dry ice pellets or dry ice snow.
- a device for conveying within the meaning of the invention can also be referred to as a transport system.
- blenders for the dry ice air mixture additionally had mostly knockers on the ice containers, which were usually designed as funnels. The knocker loosens the ice to prevent clumping.
- knockers loosens the ice to prevent clumping.
- In known devices separate devices and thus a variety of components are required for dosing and locomotive core.
- the object underlying the invention is to design a device or a transport unit of the type mentioned above so that it transports and at the same time loosens the blasting medium, in particular (dry) ice pellets or (dry) ice snow or water-soluble blasting agent.
- This should preferably be as simple as possible, especially with few components.
- the conveyor has at least one piston which is movable back and forth in the container, such that the piston can take at least a portion of provided in the container blasting medium and the delivery device can supply.
- a piston which acts as a conveying means as well as a means for loosening the jet medium.
- a body can be understood which is suitable for converting pressure and kinetic energy, without being limited to a cylindrical shape.
- the piston reciprocates in the jet medium in the container. By moving the piston in the steel medium, this is set in motion, loosened and thus can not clump or stick together.
- the piston carries part of the blasting medium and feeds it to the dispensing device.
- the blasting medium is conveyed and loosened at the same time with few components in a simple way.
- On a separate device for loosening the jet medium can be dispensed with. This saves components and thus costs.
- the simple design reduces the risk of component failure. The service life is extended and downtimes are reduced.
- a cylinder can be provided, which is open towards the container, and in which the piston is reciprocable such that at least a part of the piston can protrude into the container. In this way, the piston is guided. This makes it possible to prevent the piston from leaving its path of movement, in particular if it encounters resistance when it is pierced into the blasting medium.
- the cylinder according to the invention can be understood as a component of a piston engine. It is not limited to a cylindrical shape, but rather has an interior space in which the piston according to the invention can be moved back and forth.
- the cylinder may have an output channel, which can be supplied to the blasting medium entrained by the piston.
- the output channel can be used to simply connect a line, for example, to a blasting gun.
- the piston can be repeatedly reciprocated, in particular oscillatingly.
- a drive in particular a pneumatic, hydraulic or electric drive, be provided for moving the piston, with which simply a particular continuous promotion and loosening of the jet medium can preferably be done automatically.
- the piston may have at least one receiving means, in particular a recess, for entraining blasting medium.
- a receiving means in particular by its receiving volume, a flow rate of blasting medium per cycle of movement of the piston can be easily specified, so that with the device according to the invention a dosage of blasting medium from the container is easily possible.
- the jet medium can get into the recess and is carried along during the movement of the piston.
- the piston can advantageously be shaped as a displacer, at least in a region that is reciprocable in the container , in particular tapering towards an end face.
- At least one fluid channel in particular an air channel, can be provided, via which a fluid can flow for advancing the jet medium entrained by the piston.
- the jet medium conveyed by the piston can simply be mixed with the fluid from the fluid channel, in particular air, and be moved therewith.
- the oscillation amplitude, in particular the stroke height, and / or the oscillation frequency, in particular stroke frequency, of the piston can be varied.
- the object is achieved in that a piston oscillates in the ice.
- the essential advantage of this embodiment of the transport system according to the invention is that the ice is conveyed and loosened at the same time in a simple manner.
- the ice can be loosened by the stroke of the piston in the ice.
- Figure 1 shows schematically a side section of a dry ice container with a piston for För 1 - countries of dry ice, which is located in an upper position in the dry ice container;
- Figure 2 shows schematically a side section of the dry ice container of Figure 1, wherein the piston is in a lower position.
- FIGS. 1 and 2 there is shown an apparatus for conveying dry ice 12, generally designated by the reference numeral 10, which comprises a dry ice container 14 which is charged with dry ice 12.
- Figures 1 and 2 show a side view of the dry ice container 14, formed as a funnel, a vibrating piston 16 and an ice outlet.
- the conveying device 18 comprises a cylinder 20, in the interior 22 of which the piston 16 can be moved back and forth between an upper position shown in FIG. 1 and a lower position shown in FIG.
- the interior 22 of the cylinder 20 is open on its side facing the dry ice container 14 and its side facing away from the dry ice container 14, so that the piston 16 in its upper position and its lower position can protrude from the inner space 22 in part.
- a first transverse channel 26 which comes from the outside of the cylinder 20 and is open there, opens into an air opening 24 in the inner surface of the cylinder 20 bounding the inner space 22. Through the first transverse channel 26 and the air opening 24, air can flow into the interior 22.
- a second transverse channel 28 leads to the discharge of the dry ice 12 to the outside of the cylinder 20 and is open there.
- a dry ice line 32 shown in FIG. 2, which leads to a blasting gun or another dispensing tool for dry ice 12 which is not shown here and which is of no further interest here.
- the piston 16 is provided with a recess 34 into which the dry ice 12 falls. The recess 34 extends along the peripheral side of the piston 16.
- the dry ice container 14 facing side of the piston 16 is tapered.
- the piston 16 can be moved by means of pneumatic, hydraulic or electric drive 36.
- the piston 16 protrudes so far into the dry ice container 14 with its pointed side that the recess 34 is located outside the interior 22 in the dry ice container 14.
- the dry ice 12 in the recess 34 is entrained by the piston 16, wherein the entrained amount among other things by the receiving capacity of the recess 34 is given. In this way, simply a dosage of the conveyed dry ice 12 is realized.
- the delivery rate of dry ice 12 can be influenced by the oscillation frequency of the piston 16.
- the invention is not restricted to the conveying, metering and loosening of dry ice 12. Rather, it can also be used for other, preferably pellet, snow, granular or granular jet media, for example ordinary ice, dry ice pellets, dry ice snow or water-soluble jet media ,
- the inner space 22 of the cylinder 20 may be closed completely or partially instead of open on its side remote from the dry ice container 14, provided that the extent of the interior 22 of the cylinder 20 in the direction of movement of the piston 16 is sufficient to accommodate the piston 16 to such an extent the recess 34 overlaps with the transverse channels 26 and 28.
- transverse channels 26 and 28 and obliquely running channels can be used.
- the dry ice 12 located in the recess 34 can be supplied by means of compressed air from the first transverse channel 26 via the second transverse channel 28 of the dry ice line 32 instead of by means of negative pressure.
- the piston 16 and the cylinder 20 may also be arranged so that the piston 16 moves obliquely to the vertical.
- the amount of dry ice 12 to be delivered can also be achieved by limiting the depth of immersion of the piston 16 into the dry ice 12 in the dry ice container 14. For example, the piston 16 can only be moved so far out of the cylinder 20 that the recess 34 is only partially released.
- a plurality of pistons 16 can also be used for removing, dosing and loosening the drying ice 12.
- the piston 16 can also be tapered in another form, for example bent or spherical, concave or convex.
