Definitions

  • the invention relates to a rotating nozzle, in particular for a device for cleaning articles with aggressive cleaning liquids, wherein the nozzle has a nozzle body, with at least one liquid supply and a liquid outlet nozzle.
  • Such rotating nozzles are known. They are frequently used for devices for cleaning articles with aggressive cleaning fluids, used for example in the food industry for cleaning of pallets, trays, sheets and so on used there.
  • a device for cleaning with a rotating nozzle is from the earlier application of the applicant DE 199 63 496 A1 known.
  • a nozzle main body is provided on which a nozzle spray pipe is formed or arranged.
  • the nozzle body has a bearing tube, in the interior of which is the storage.
  • the nozzle body is supplied with cleaning fluid through the bearing tube and via a feed, which is designed, for example, as a pipe socket.
  • a feed which is designed, for example, as a pipe socket.
  • a nozzle channel is provided, via which the nozzle spray pipe or the nozzle is supplied with cleaning liquid. Since the nozzle is designed to be rotating, the pipe socket must be sealed to the nozzle body and to the storage to prevent the leakage of the liquid.
  • the nozzle body must be rotatably mounted, so that the desired rotation effect also occurs.
  • a seal assembly in the interior of this body, which seals the pipe socket as a liquid supply.
  • This may be, for example, three seals that seal the nozzle body to the outside. Since the ball bearings are also supported in particular on the pipe socket and are arranged in a bearing sleeve, it is possible that in case of leaks due to the selected arrangement, cleaning liquid exits and this is then inevitably led into the bearings.
  • This sensitive bearings, but also high-quality bearings are very quickly damaged so that they are useless in no time. Consequently, one must then shut down the device for cleaning to change both the seals and the bearings.
  • the invention is based on the prior art described above and proposes to achieve the object a rotating nozzle, in particular for a device for cleaning articles with aggressive cleaning liquids, wherein the nozzle has a nozzle body, with at least one liquid supply and a liquid outlet nozzle , wherein the nozzle main body has a bearing tube, which simultaneously forms the liquid supply and the bearing is provided on the outer circumference of the bearing tube and a fixed pipe socket, which is inserted into the bearing tube, wherein the pipe socket is designed as a supply of liquid to the nozzle body and a seal of a Inner circumference of the bearing tube is provided to an outer periphery of the pipe socket.
  • the liquid supply takes place via a pipe socket, which can be inserted into the bearing tube and the seal between the inner circumference of the bearing tube and the outer periphery of the pipe socket is provided.
  • a pipe socket which can be inserted into the bearing tube and the seal between the inner circumference of the bearing tube and the outer periphery of the pipe socket is provided.
  • the bearing tube provides a liquid guide.
  • a liquid guide takes place in various ways according to the invention.
  • the subject invention presented here also includes a second variant, in which the bearing tube receives a further element, for example a pipe socket, and thus this additional element in turn the line and leadership of the liquid takes over.
  • the solution proposed here according to the invention thus comprises both an immediate fluid guide through the bearing tube, as well as an indirect fluid guide through the bearing tube.
  • a skillful development which is particularly preferred, provides that at least one seal piece is provided as a seal, which seals the gap between the bearing tube and the pipe socket.
  • the seal piece has the advantage that it seals in both directions, namely the bearing tube and the pipe socket, without having to additionally provide seals. Of course you can also provide additional seals either inside or outside of the packer. In the simplest variant, however, it is sufficient if the seal piece itself is formed from a sealing material and is arranged tightly between the bearing tube and pipe socket. In this case, the seal piece has the advantage that it remains replaceable and the sealing axis is provided, so to speak, floating, so of course the wear can also be kept relatively low.
  • the sealing piece is provided so that it has, for example on the outer circumference of an O-ring, which secures the seal piece in the bearing tube against rotation.
  • Another seal piece is then formed exactly the other way round in such a way that on the inner circumference of the seal piece, so facing the pipe socket, an O-ring is arranged, which in turn secures this seal piece against rotation to the pipe stub.
  • the two adjoining packings are designed so that a sliding gap seal is formed or formed by the side surfaces of the packings. This packer then seals the inner circumference of the bearing tube to the pipe socket out.
  • sealing pieces also has the advantage that here the sealing surface is significantly increased overall compared to the solution of the prior art, where only the sealing rings have sealed, which of course counteracts premature wear.
  • the sliding sealing surface between the individual sealing bodies can also serve to produce the actual seal according to a development.
  • a development of the invention provides that on the at least one seal piece, a seal on the outer and inner circumference of the sleeve-shaped seal piece is provided.
  • a seal on the outer and inner circumference of the sleeve-shaped seal piece is provided.
  • at least two seal pieces side by side are arranged and a seal, for example in the form of an O-ring on the outer circumference of the first seal piece and a further seal on the inner circumference of the seal piece is provided.
  • sealing pieces preferably five to six sealing pieces, each having alternately an outer and an inner seal arranged.
  • This seal can serve both the seal, but also in particular the setting of the seal piece on the respective side, ie facing the bearing tube or the pipe socket.
  • the sealing piece is made of a sealing material, such as carbon, ceramic, plastic or metal, such as brass, bronze, carbide or the like. This gives excellent sealing properties already by the packer itself and a long life of it formed seal. It is now possible according to the invention, to select the appropriate material for the sealing piece for the particular application. For example, it is possible to use sealing materials made of silicon dioxide or similar high-grade materials for abrasive media.
  • a development of the previously described embodiment proposes that a plurality of sealing pieces are provided and the sealing pieces are formed of different materials.
  • the provision of different sealing materials offers the advantage that one here on the one hand quite well-sealing material, which is possibly a little softer and therefore faster wears alternately with somewhat harder materials provides to maintain the life of the seal in particular.
  • the pipe socket or the bearing tube will initially be supported on the slightly harder materials and thus prevent the wear of the slightly softer material. This also makes it possible to significantly increase the life of the particular in question sealants and the seal.
  • a seal on the seal piece.
  • this may, as already mentioned, be an O-ring.
  • the invention proposes that at least one, preferably two or more ball bearings are provided as the bearing, which are arranged on the outer circumference of the bearing tube.
  • the storage next to the or the ball bearings has a bearing housing which engages on the nozzle body facing side in a groove provided there corresponding with slight play.
  • the advantages of such a configuration are obvious.
  • the camp is also protected from the outside against any impinging spray, which, for example, as an atomized liquid course in the cleaning chamber of the cleaning device, in which the rotating nozzle is usually arranged, occurs.
  • the corresponding groove in the nozzle body is cleverly chosen so that there is a certain paragraph, through which also no liquid can enter.
  • the game is of course necessary so that the nozzle body can rotate relative to the bearing housing. Due to the construction arrangement of the rotating nozzle body, any penetrating cleaning agent is expelled from the rotating nozzle body by the centrifugal force through the groove.
  • the bearing housing serves as a lining for the ball bearings and preferably has a splash guard, which is provided on the nozzle body facing side and / or on both sides of the bearing or a gasket is provided.
  • the splash guard or moisture protection for the ball bearings is further increased, so that the risk that any cleaning fluid enters the ball bearings, is almost impossible.
  • a cover flange is provided on the pipe socket, on which a engaging in the bearing housing Approach is provided, which serves as a further splash guard for or the ball bearings. This now secures the side that faces away from the nozzle body. Now, the splash guard for the ball bearings is complete and it can not penetrate any moisture or cleaning liquid there.
  • a collecting chamber is provided in the interior of the cover flange. This serves for the collection of possibly exiting detergent or cleaning fluid.
  • This collecting chamber has, as already mentioned briefly above, an outlet opening, from which then passes the exiting cleaning liquid into the open. This indicates to the operator or operators that there is now a leak at the seal. It will therefore be relatively short term maintenance can be initiated without large fluid losses occur. Again, this is a further improvement over the prior art solutions.
  • connection interface for connection to a liquid-carrying line of the device for cleaning on the Abdeckflansch on the side facing away from the nozzle in the installed state.
  • the nozzle is then connected to a liquid-carrying supply line for the cleaning liquid via this connection interface.
  • An additional advantage that occurs through this configuration is that due to the fact that the cover flange with the outlet openings of the The collecting chamber is not moved, the operator is very easily possible, even with the smallest leakage quantities of liquid, to recognize this immediately and to initiate the necessary repairs. It is furthermore advantageous if at least one nozzle tube is arranged on the nozzle main body as a liquid outlet nozzle. With this nozzle tube, the liquid jet can be very accurately directed to the good to be cleaned. In particular, it is thus possible to realize different angles of attack, in the event that different objects are to be cleaned.
  • the invention also relates to a rotating nozzle for a device for cleaning articles with aggressive cleaning liquids, wherein the nozzle has a nozzle body on which a bearing tube is arranged liquid-tight or formed on the outer circumference of the bearing tube storage in the form of at least one surrounding a ball bearing Bearing housing is provided, which engages in a circumferential groove on the nozzle body, in particular with light play or non-contact, wherein the liquid supply via a pipe socket, which is inserted into the bearing tube and the seal between the inner circumference of the bearing tube and the outer circumference of the pipe socket in the form at least a seal piece is provided.
  • a pipe socket which is inserted into the bearing tube and the seal between the inner circumference of the bearing tube and the outer circumference of the pipe socket in the form at least a seal piece is provided.
  • the rotating nozzle main body has on its end face a maintenance opening which can be closed by a removable closure.

  • the maintenance opening has a larger diameter than the inner opening of the bearing tube and the inner opening of the bearing tube is in communication with the maintenance opening.
  • the inner opening of the bearing tube should be accessible through the maintenance opening for the reason that the sealing pieces can be removed and replaced. For this it is favorable to provide no undercuts in the inner opening. Alternatively, it is possible to arrange undercuts so that their bright inner dimension is still large enough not to hinder the expansion of the seal. It is also possible that an undercut, so a protruding edge or ring, is provided, and the assembly or disassembly is carried out on the axially opposite to the closure region of the bearing tube.
  • the seals are replaced as follows: Unscrew the cover flange, take off the pipe socket, remove the plug (screw) and push out the seals from the side of the plug in the direction of the pipe socket / cover flange.
  • the pushing out of the seal, as described, has the advantage that the inner surface of the bearing tube is not damaged.
  • the sealing pieces can be removed and replaced by the maintenance opening without the rotating base body having to be dismantled.
  • the seals can be equipped in a variant with an element which cooperates with a puller and thus allows withdrawal of the seals from the annular gap.
  • the spring is formed, for example, as a plate spring, an elastomer or the like.
  • the use of a spring offers in particular higher pressures (of the cleaning liquid) and / or for liquids with abrasive components advantages.
  • the spring pushes the seals together permanently, so that no leakage gap arises. If seal parts wear in the axial direction, the spring travel is no longer sufficient at some point. Then new gaskets can be inserted through the screw plug.
  • the liquid flowing through the nozzle flows through one or more radial bores in the wall of the closure designed as a hollow element.
