Definitions

the invention relates to a jet cleaner for cleaning, rinsing, disinfecting and sterilizing in particular predominantly closed, difficult to access container interior spaces with the aid of liquid media.
liquid driven jet cleaner which are equipped as a lance body with a nozzle body and are connected via a coupling part with a drive motor.
a lance which consists of a tube in which a drive axle driven by a drive axis is guided axially, at the pipe outlet, a nozzle body is arranged, which is driven via the drive shaft.
the lance tube is closed but not the nozzle body.
the cleaning liquid is conveyed through the pipe interior and a pipe closure part in the nozzle body and out of this through the nozzle openings back out.
a self-cleaning nozzle Another possibility for the removal of particulate material is the use of a self-cleaning nozzle, wherein an increase of the pressure medium pressure causes, for example, a poppet valve together with attached sealing means itself stands out from a special housing which releases the metering. This leads to a change in the Outlet dimensions of the metering orifice so that stuck particles can be removed by the fluid flow.
a self-cleaning spray nozzle the company Spraying Systems Co., US, known, which is formed with a standard fitting as a nozzle body.
a unitized valve assembly is partially inserted into and secured to the fitting.
the valve assembly comprises a secured valve set which is biased by a spring against a spray head such that the valve seat forms a seal with the spray head.
the spray head is formed so that it does not form a complete seal with the valve seat, wherein a gap in the seal forms a metering orifice, from which the fluid is sprayed out at normal pressure medium pressure with a predetermined spray pattern.
a force is applied to the spray head sufficient to overcome the spring bias, the spray head separates from the valve seat, thereby interrupting the seal formed between the two parts and permitting fluid flushing of the outlet devices.
the required force can be carried out by hand or generated by increasing the pressure medium pressure.
This self-cleaning spray nozzle has a complicated construction, which is limited to the cleaning of the nozzle body and works only by additional manual or mechanical pressure.
the DE 691 21 248 T2 Toftjejorg, DK discloses a device for cleaning closed spaces by sprayed liquid.
the apparatus comprises a housing having a fixed part to which the liquid is supplied and on which is mounted a rotatable member on which a hub with spray nozzles is suspended in bearings and a turbine driven by the liquid and a planetary gear mechanism is mounted in the fixed part for rotating the rotatable member and the nozzles in such a way that the liquid which is sprayed during rotation through the nozzles, the entire interior of the closed spaces can clean, wherein the fixed part comprises a toothed edge which engages with a serrated edge on the hub, both edges being surrounded by the housing.
the apparatus is characterized in that the gear, the toothed edges and the bearings between the parts extend in a part of the liquid flow in such a way that the liquid is passed out through the device through slots outwardly between the fixed part and the rotatable part and between the rotatable part and the hub are formed.
These cleaning devices are used in particular for cleaning tanks in the food industry, the chemical and pharmaceutical industry and similar areas, where it is particularly cleanliness of such spaces.
the device described here for cleaning closed rooms has a self-cleaning in the nozzle body area, but is characterized by a compact, complex construction, with which the cleaning of a lance body is not feasible.
WO 2004/060577 A1 is also a spray system with automatic nozzle cleaning device known.
which consists of an outer tube with a number of axially arranged spray nozzles, in which a drive axle with radially arranged brushes is arranged.
liquid is passed, which extends between the rotating drive shaft and the outer tube, whereby the inner wall of the outer tube and the nozzles are cleaned by the rotating drive shaft with the brushes and the liquid and the contaminated liquid can drain over an outflow.
This self-cleaning device is essentially suitable for cleaning the nozzles.
the radial brush assembly on the drive axle is also subject to high wear.
a jet cleaner in particular for cleaning containers such as tanks and the like with the aid of liquid media having the features of claim 1.
the second fluid circuit according to the invention requires no additional components on the known jet cleaner. It is only a liquid supply member, two nested tubes and a closed spherical nozzle body required, which are interconnected according to the preamble of claim 1 and pump with a conventional motor gear fluid in the lance body and the nozzle body.
The, intended for the cleaning of the Zielstrahlrutzs, second separate liquid circuit is provided in particular for cleaning in the high pressure region and, according to claim 2, by a simple separate channel guide via a second liquid inlet opening in the liquid supply member, an annular cavity between the outer tube wall of the inner tube and the inner Pipe wall of the outer tube of the lance body, the axial openings formed in the fixed gear body and the outlet slots in the rotation body.
the liquid guide takes place on the, according to claim 3, defined way.
the device arrangement according to the invention has the great advantage that the structural design of the target jet cleaner by the largely closed lance body and the lance head, is relatively resistant to contamination. Nevertheless occurring contamination of the jet cleaner, for example, by rising liquids in the container or splashed dirt particles that attach to the device can be easily removed after completion of the cleaning process.
the target jet cleaner must be removed from the cleaned container, the liquid supply interrupted via the conventional liquid inlet opening and the second liquid circuit according to the invention via the second liquid inlet opening to the liquid supply part to be opened.
This cleaning process of the jet cleaner saves extensive time-consuming and costly dismantling, the renewed Assembly of the device and ensures its rapid repeated readiness. In addition, soiling of clean containers with residues of cleaning agents, chemicals disinfectants or similar substances that have become lodged in the lance body and the lance head during a cleaning process is avoided.
Another advantage is the second variant of the jet cleaner according to the invention, according to claim 4, which is particularly suitable for use in the low pressure area and in which next to the through holes in the fixed gear body and the outlet slots in the rotating body of the lance head, a through hole is attached to the inner tube, whereby the liquid , according to claim 5, not only on the inner tube to the lance head for cleaning a container can be transported, but at the same time and during this cleaning process in the lance body and the lance head to the self-cleaning can be conducted.
no additional components for conventional jet cleaner are needed and a costly disassembly and repeated assembly of the jet cleaner avoided.
the time required for a separate self-cleaning process is saved.
a second separate liquid circuit which is preferably provided for the high-pressure cleaning of a food tank. It comprises a liquid supply part 1 with a liquid high-pressure connection 1.1, a liquid inlet opening 1.2, and a second separate liquid inlet opening 1.5, which leads in the axial direction angled into the lance body 2, a likewise simplified in the drawing, the liquid spindle 1.3 and arranged on this coupling part 1.4 to Connection with a geared motor.
a lance body 2 consists of an inner tube 2.1, which serves as a pressure tube and drive extension and an outer tube 2.2 which serves as a support tube and in which the inner tube 2.1 extends, whereby the two tube walls within the outer tube 2.2 form an annular axially extending cavity 6.
an annular rotary body 3.1 On the inner tube 2.1 on the one hand via an annular rotary body 3.1, a largely closed spherical lance head 3 and on the other hand, the liquid spindle 1.3 is arranged, which is stored in the liquid supply part 1 and releasably connected to the coupling part 1.4.
a gear body 4 is arranged with a coaxial sprocket and preferably with two axial through holes 4.2, which is fastened with a retaining screw 4.1 radially on the outer tube 2.2, with only the fixed coaxial sprocket of the gear body 4 protrudes from the outer tube 2.2 and on the other hand, the liquid supply part 1 is detachably arranged.
the spherical closed lance head 3 is detachably connected via the annular rotary body 3.1 with an axial bore 3.1.1 with the inner tube 2, wherein in the rotation body 3.1, a simplified, coaxially mounted nozzle carrier 3.2 with molded cover 3.2.1, crosswise through openings 3.2.
the jet cleaner is removed from the tank.
the second embodiment shows a jet cleaner of the above-described basic category, which can be preferably used for low-pressure work.
This embodiment includes only one liquid circuit which is why the liquid supply part 1 has only one liquid inlet opening 1.2 and the inner tube 2.1, in addition to the preferably two axial holes 4.2 in the gear body 4 and also preferably two outlet slots 3.1.2 in the rotation body 3.1, provided with a through hole 2.3.
the cleaning liquid from the inner tube 2.1 in the annular axial cavity 6 between the inner tube 2.1 and the outer tube 2.2 through the axial openings 4.2 in the gear body 4 in the lance body 3 and from there via the outlet slots 3.1.2 of the rotation body 3.1 also passed into the tank to be cleaned.
This design allows the cleaning of a container and at the same time during this process, the cleaning of the jet cleaner itself.
