Definitions
- Nozzles are known that have cylindrical bores, whereby the cleaning fluid is sprayed through the bore and directed through the nozzles onto the containers or surfaces to be cleaned. In order to avoid blockages, e.g. due to grain jamming, these nozzles must be cleaned regularly.
- the object of the invention is to provide a device which has a reduced cleaning requirement and a reduced sensitivity to clogging.
- a device for passing through a fluid comprising at least one nozzle with a flow channel that extends between a nozzle inlet and a nozzle outlet
- the flow channel extends from the nozzle inlet to the nozzle outlet with an opening angle in the range of 1 ° to 2.5 ° expanded.
- the invention thus provides a device in which particles that are flushed into the nozzle with the fluid through the nozzle inlet are transported along an expanding flow channel to the nozzle outlet. On Due to the widening flow channel, the probability that a particle will become trapped in the flow channel is reduced.
- the opening angle is the angle that walls or wall sections that extend from the nozzle inlet to the nozzle outlet include on opposite sides of the flow channel. The value of the opening angle is in the range of 1° to 2.5°. The opening angle preferably has a value of 1.5°.
- the flow channel can continuously expand from the nozzle inlet to the nozzle outlet and can z. B. expand funnel-shaped or conical, so that the channel cross-section constantly increases.
- the nozzles can, for example, be designed to be rigid so that they do not change their orientation relative to the device after assembly or production.
- the fluid can preferably be liquid, more preferably water, and can be referred to as a cleaning fluid. This provides a device which has a reduced need for cleaning and a reduced susceptibility to clogging and thus increased functional reliability.
- the widening flow channel results in a larger treatment area when the jet hits, compared to a cylindrical nozzle, with the same nominal nozzle diameter, spray pressure and delivery volume of the fluid.
- the device may have a base plate, with the at least one nozzle extending through the base plate.
- the at least one nozzle can be mounted, for example, above a fluid outlet opening. Fluid exiting the fluid outlet opening is then guided directly through the nozzle. If several nozzles of the device extend through the base plate, several nozzles can be mounted simultaneously above one or more fluid outlet openings.
- the at least one nozzle and the base plate can be made in one piece, for example.
- the base plate can be manufactured cost-effectively at the same time as the nozzles. Furthermore, there is no need to assemble the nozzle and the nozzle is already correctly aligned on the base plate. According to a further example, the number of nozzles can be between one and four, preferably three.
- the nozzles can e.g. B. be arranged in a triangle.
- a tip of the triangle can be aligned along a conveying direction of containers. Starting from a direction transverse to the conveying direction, the nozzle arranged at the aligned tip of the triangle lies between the other two nozzles.
- the outer nozzles can each direct the cleaning fluid onto an outer surface of the containers.
- the nozzle located at the aligned tip can direct the cleaning fluid into the interior of the container. This means that the entire container can be wetted with cleaning fluid.
- the device can further consist of a plastic material or metal material.
- the device e.g. B. in an injection molding process
- the device can be easily produced in large quantities.
- corrosion of the material of the device can be avoided.
- the nozzle inlet may have a diameter between 2 mm and 14 mm, preferably between 3 mm and 9 mm, more preferably 4 mm.
- the invention relates to a system for treating surfaces of objects comprising at least one device according to the preceding description, wherein a transport path for objects extends through the system and the at least one nozzle is aligned with the transport path.
- the objects are containers.
- the treatment can include spraying, squirting, heating and/or cooling.
- the equipment may be a cleaning machine, a pasteurizer, a crate washer or a transport device.
- Figure 1 is a schematic representation of a device for passing a fluid
- Figure 2 shows a schematic cross-sectional representation of the device
- Figure 3 is a schematic representation of a system comprising the device.
- the device is referred to in its entirety below with the reference number 10, as shown in Figure 1.
- the device 10 has at least one nozzle 12, which can be arranged on a base plate 20.
- a base plate 20 In this example, three nozzles 12 are arranged on the base plate 20.
- the nozzles 12 and the base plate 20 can be formed in one piece from a plastic material or metal material. This can be done e.g. B. an injection molding process can be used.
- the at least one nozzle 12 has a nozzle inlet 16 and a nozzle outlet 18.
- a flow channel 14 extends from the nozzle inlet 16 to the nozzle outlet 18.
- the flow channel 14 establishes a fluid-communicating connection between the nozzle inlet 16 and the nozzle outlet 18.
- the flow channel 14 can be delimited laterally to the flow direction through the flow channel 14 by a first wall section 24 and a second wall section 26.
- the first wall section 24 and the second wall section 26 are arranged opposite one another and extend from the nozzle inlet 16 to the nozzle outlet 18.
- the wall sections 24, 26 are arranged at an angle to one another, which represents an opening angle a of the flow channel 14.
- the opening angle a has a value in the range from 1° to 2.5°.
- the opening angle a preferably has a value of 1.5°.
- the flow channel 14 can therefore expand conically or in a funnel shape starting from the nozzle inlet 16.
- the cross-sectional area of the flow channel 14 can therefore increase continuously along the flow direction.
- Particles that enter the flow channel 14 through the nozzle inlet 16 are transported along the expanding flow channel 14 to the nozzle outlet 18. The particle therefore does not find a hold on the walls 24, 26 of the flow channel 14. This prevents the particles from becoming jammed in the flow channel 14.
- the diameter of the nozzle inlet can be between 2 mm and 14 mm, preferably between 3 mm and 9 mm, most preferably 4 mm.
- FIG. 3 shows a system 30 which includes the device 10.
- the base plate 20 of the device 10 can have a through-opening 22 that extends through the base plate 20.
- the device 10 can be fastened in the system 30 by means of a fastening element arranged through the through-opening 22.
- the fastening element can be a screw, for example.
- the fluid can flow through the nozzles 12 at a pressure of approximately 0.8 bar and, after emerging from the nozzle outlet 18, hits the object 32 or its surface. Due to the widening flow channel 14, the emerging fluid jet has an enlarged impact area compared to a cylindrical nozzle with the same nominal diameter.
- the system 30 can be designed as a cleaning machine, pasteurizer or crate washer.
- the objects 32 have an interior space, e.g. B. if they are designed as a container, they can be transported upside down along the transport path with a container mouth pointing downwards.
- a first nozzle 12 can be arranged to discharge the fluid into the interior of the container.
- the other two nozzles 12 can discharge the fluid onto the outer surfaces of the container.
