Description
Technical Field
The invention relates to a nozzle beam for processing fibers with water jets, comprising a longitudinally extending upper part, in which a pressure chamber of elongate design is arranged, wherein the pressure chamber has an end face with an opening for supplying water and an opposite closed end face, and wherein a pressure distribution chamber extending parallel to the pressure chamber is arranged in the upper part, a plurality of flow openings being distributed over the length of the upper part, which flow openings are located in an intermediate wall between the pressure chamber and the pressure distribution chamber, through which flow openings water from the pressure chamber can be conducted into the pressure distribution chamber; the nozzle beam also has a lower part which is arranged next to the upper part in a liquid-tight manner and extends in the longitudinal direction, and a nozzle plate with small holes for water discharge is accommodated in or supported on the lower part; a slit extending between the pressure distribution chamber and the nozzle plate for allowing a water flow to act on the nozzle plate is provided in the upper member.
Background
DE 102005055939B 3 discloses a nozzle beam for the treatment of textiles with water jets. The textile fabric is processed by means of a plurality of water jets produced in a row, which extend over the entire width of the fabric web moving under the water jets and act on the fabric web, for example. For this purpose, the nozzle beam has a water connection, by means of which water enters the pressure chamber via the opening. For example, water enters the pressure chamber through the openings by means of a generated pre-pressure of 250 bar, wherein the inflow speed of the water through the openings can reach, for example, 8m/s, and the water flow speed can reach about 2.5m/s in the center of the pressure chamber. In order to avoid the occurrence of intensified turbulence in the pressure chamber, it has proven advantageous to let the water enter the pressure chamber through the openings on one side. The nozzle beam is long and narrow, wherein the nozzle beam is formed primarily by an elongate upper part and an elongate lower part. The lower part is arranged in a liquid-tight manner on the side of the upper part directed toward the textile, and the water jet is generated by a plurality of small holes arranged in the nozzle plate via the lower part and the nozzle plate arranged in or on the lower part.
In order to make the water jet produced through the small holes in the nozzle plate as uniform as possible, it is desirable that the pressure is distributed substantially evenly over a large length of the nozzle beam. For this purpose, the pressure chamber is separated from the pressure distribution chamber, and a plurality of through-flow openings in an intermediate wall between the pressure chamber and the pressure distribution chamber extend between the pressure chamber and the pressure distribution chamber. The pressure is thereby equalized across the width of the nozzle bar, so that neither a high pressure arises in the vicinity of the inflow opening of the feed water, nor a lower water pressure arises in front of the nozzle plate on the opposite, remote feed water side. Uniform processing of the textile fabric can only be ensured by a uniform water jet over the entire width of the nozzle beam.
A preferred aim in the construction of such nozzle beams is to achieve as low an overall pressure loss as possible by equalization of the water pressure on the inner side in front of the orifice in the nozzle plate. In an apparatus employing such a nozzle plate, the nozzle beam is exposed to the action of water for a long period of time, so that any pressure loss in the nozzle beam is accompanied by a loss of energy in the operation of the apparatus. The aim in the construction of the nozzle beam is therefore to reduce as far as possible the pressure loss starting from the opening supplying water into the pressure chamber to the water outflow from the outlet orifice of the nozzle plate, in addition to making the overall water jet structure uniform.
In EP 0725175B 1, in order to equalize the water pressure in front of the water outlet in the nozzle plate, the slits are configured such that an intensified vortex is generated which acts uniformly on the nozzle plate from the inside, but at the same time is accompanied by a higher pressure loss.
Furthermore, it is also desirable that the nozzle beam be constructed as simply as possible in terms of construction and that simple maintenance be achieved. For example, the nozzle beam must be cleaned at regular intervals and the nozzle plate must in particular be removable in a simple manner. In a flow-optimized configuration of the upper part with pressure chamber and pressure distribution chamber, it has been found that a further reduction in the pressure loss can be achieved by a geometric adjustment, so that, for example, a narrow slit in the nozzle plate leading out of the pressure distribution chamber can be optimized, as described in EP 0725175B 1.
Disclosure of Invention
The object of the invention is to further develop a nozzle beam for the processing of fibers with water jets, wherein the nozzle beam should have a low overall pressure loss, and wherein the nozzle beam should be developed as follows: the water jets produced by the orifices in the nozzle plate are as identical as possible to each other over the entire width of the nozzle beam. Furthermore, the nozzle beam should be designed to be as small as possible in terms of installation space, while avoiding the aforementioned problems of the invention.
The object of the invention is achieved by a nozzle beam for the production of textiles by means of water jet.
The present invention comprises the following technical teaching: the pressure chamber is cylindrical and has a circular cross-section with a diameter of 70mm to 90mm, and the pressure distribution chamber is cylindrical and has a circular cross-section with a diameter of 30mm to 40 mm.
The nozzle beam comprises pressure chambers and pressure distribution chambers of circular cross-section with corresponding diameters, which configuration has a surprisingly positive effect on equalizing the discharge pressure via the slits towards the nozzle plate, while reducing the overall pressure loss within the nozzle beam. The nozzle beam is designed in particular for feeding water at a rate of up to approximately 8m/s at a prepressing pressure of 250 bar. The ratio of the dimensions of the pressure chamber to the pressure distribution chamber advantageously allows water to flow through the throughflow openings in the intermediate wall at speeds of, for example, up to 11 m/s.
If the pressure chamber and/or the pressure distribution chamber have too large or too small a diameter, either a flow dead space results, which leads to an uneven pressure distribution, or a pressure difference results from the open end side of the upper part to the other end side of the opposite feed-free opening via the throughflow openings in the intermediate wall. This adverse effect on pressure distribution and overall pressure loss is minimized when the ratio of the pressure chamber diameter to the pressure distribution chamber diameter is optimized, i.e., 70mm to 90mm for the pressure chamber diameter and 30mm to 40mm for the pressure distribution chamber diameter.
It is particularly advantageous if the pressure chamber has a diameter of 75mm to 85mm and the pressure distribution chamber has a diameter of 33mm to 37 mm. It can furthermore be stated that it is more advantageous when the pressure chamber has a diameter of 80mm and the pressure distribution chamber has a diameter of 35 mm. As a result, a minimum overall pressure loss is obtained when the pressure distribution chamber diameter is slightly less than half the pressure chamber diameter.
A further significant influence is determined by the length of the throughflow bore in the intermediate wall between the pressure chamber and the pressure distribution chamber. The distance of the center axis of the pressure chamber from the center axis of the pressure distribution chamber therefore also influences the overall pressure loss in the nozzle beam and the water pressure distribution over the length of the nozzle plate, which is as uniform as possible on the inner side in front of the orifice. It is particularly advantageous if the distance from the center axis of the pressure chamber to the center axis of the pressure distribution chamber is 80mm to 100mm, preferably 85mm to 95mm, particularly preferably 92 mm. Correspondingly, the length of the throughflow orifice is 34.5 mm. The through-flow opening is further advantageously designed in a segmented manner, and the diameter of the through-flow opening at the inlet into the pressure chamber is smaller than the diameter of the through-flow opening at the inlet into the pressure distribution chamber.
A further advantage is that a bluff body is provided which is arranged cylindrically in the pressure distribution chamber, wherein the bluff body is oblong cylindrically with a diameter of 20mm to 25mm and/or 22.5 mm. It is particularly advantageous if the bluff body has an elongated cylindrical shape at its end and/or if the bluff body has spacers distributed over its length, by means of which the bluff body is arranged centrally and fixedly in the pressure distribution chamber. As is given above, when the bluff body is arranged centrally in the pressure distribution chamber, very favorable flow characteristics are obtained within the pressure distribution chamber. In other words, the bluff body is formed over its entire surface at the same distance from the wall of the pressure distribution chamber, so that the flow cross section of the water from the through-opening to the slit around the bluff body remains substantially the same. In this case, it can be ascertained that with a bluff body configured in this way and arranged in the pressure distribution chamber, only minimal or no turbulence is produced. Accordingly, the pressure loss is minimized while optimizing the pressure distribution over the length of the nozzle beam as far as possible.
A further advantage is achieved when the pressure chamber located in the upper part is closed with a closing element on at least one end side of the upper part, and the closing element has an opening for supplying the pressure chamber with water. In this case, it is also conceivable for the pressure chamber to be closed by the material of the upper part on the side opposite the closing element with the opening. For production-technical reasons, it is advantageous if the upper part has a substantially uniform material cross-section over its entire length.
It is also advantageous if the pressure distribution chamber in the upper part is closed with a closing element on the end face of the upper part opposite thereto. In this case, it is particularly advantageous if the bluff body is accommodated with its ends between the closure elements. If the bluff body has to be removed from the pressure distribution chamber, for example for the purpose of cleaning the pressure distribution chamber, it is sufficient to remove one of the two closing elements at the end side of the upper part.
Drawings
Further measures for improving the invention are shown below with the aid of the figures together with a description of a preferred embodiment of the invention.
In the figure:
FIG. 1 shows a cross-sectional view of a nozzle beam for processing textiles with water jets, wherein the cross-section extends longitudinally through the nozzle beam;
fig. 2 shows a cross-sectional view through the nozzle beam according to fig. 1 along the section line a-a shown.
Detailed Description
Fig. 1 shows a cross-sectional view through a nozzle beam 1 for processing fibres with water jets, and fig. 2 shows a cross-sectional view through the nozzle beam 1 along section line a-a, wherein section line a-a extends transversely to the section through the nozzle beam 1 in fig. 1. The nozzle beam 1 will be further described with reference to fig. 1 and 2.
The housing of the nozzle beam 1 has an upper part 10, which upper part 10 is screwed to a lower part 16 at a plurality of points in length by bolts 24. The upper part 10 has two perforations 11 and 13 extending in the longitudinal direction, wherein the upper perforation constitutes the pressure chamber 11 and the lower perforation constitutes the pressure distribution chamber 13. The pressure chamber 11 and the pressure distribution chamber 13 are open on the end side of the upper part 10, the closure element 22 of the pressure chamber 11 sealing the pressure chamber 11 in a liquid-tight manner and the closure element 23 of the pressure distribution chamber 13 sealing the pressure distribution chamber 13 in a liquid-tight manner. The closing element 22 for closing the pressure chamber 11 has a pressure measuring device 25 and the closing element 22 for closing the pressure chamber 11 has an opening 12 on the right, through which opening 12 water can be supplied to the pressure chamber 11 by means of a water connection, not shown in detail.
The pressure chamber 11 is separated from the pressure distribution chamber 13 by an intermediate wall 15, wherein the intermediate wall 15 is formed by the cross-sectional area of the upper part 10. A plurality of throughflow holes 14 located in the intermediate wall 15 connect the pressure chamber 11 to the pressure distribution chamber 13 over the length of the nozzle beam 1, so that the water flow flowing into the pressure chamber 11 flows into the pressure distribution chamber 13 uniformly distributed over the length of the nozzle beam 1. The pressure distribution chamber 13 opens downwards, more precisely through a narrow slit 19 relative to the perforation diameter of the pressure distribution chamber 13, which likewise extends over the length of the nozzle beam 1.
According to fig. 2, the upper part 10 and the lower part 16 are screwed liquid-tightly and fixedly with bolts 24. The tightness is achieved by an O-ring 26, which O-ring 26 is embedded in a groove surrounding the slit 19. The spring projection 27 is embedded in a corresponding groove in the lower part 16 and in this groove there is a further O-ring 28 for sealing the nozzle plate 17.
The sectional view in fig. 1 shows a nozzle plate 17 with a plurality of small holes 18, wherein the small holes 18 are distributed on the nozzle plate 17 at equal distances from one another in the longitudinal direction. The water flow under pressure from the pressure distribution chamber 13 and from the adjacent slits 19 acts internally on the nozzle plate 17 and passes through the orifices 18 and forms water jets ejected from each orifice 18.
With the described configuration of the nozzle beam 1, the water flow flows under pressure through the openings 12 in the closure element 22 into the pressure chamber 11, uniformly distributed through a plurality of throughflow holes 14 in the intermediate wall 15 to the pressure distribution chamber 13. The bluff body 20 is fixedly accommodated between two closing elements 23 and is mounted centrally in the pressure distribution chamber 13, by means of its cylindrical configuration the pressure distribution in the direction of extension of the nozzle beam 1 is further homogenized, so that the nozzle plate 17 is subjected to substantially the same pressure over its entire length, while keeping pressure losses to a minimum. A plurality of spacers 29 arranged on the bluff body 20 are distributed over the length of the bluff body 20, the spacers 29 being disc-shaped and centering the bluff body 20 in the pressure distribution chamber 13. For this purpose, the spacer 29 is seated with its outer contour on the inside in the pressure distribution chamber 13 and is therefore supported on the inner wall. In this connection, the spacer 29 can be firmly attached to the rod-shaped or cylindrical bluff body 20. As a result, a uniform water jet is generated when the water flows through the plurality of small holes 18, so that a uniform processing of the textile over the entire width of the textile can be achieved. In addition, the advantage is achieved that the bluff body 20 can be removed from the pressure distribution chamber 13, for example for cleaning purposes, when one of the closure elements 23 is removed.
According to this embodiment, the pressure chamber 11 has a diameter of 80mm and the pressure distribution chamber 13 has a diameter of 35 mm. The pressure chamber 11 and the pressure distribution chamber 13 have a substantially cylindrical cross section over the entire length of the nozzle beam 1. The center axis of the pressure chamber 11 is spaced 92mm from the center axis of the pressure distribution chamber 13. This results in a desired length of the throughflow holes 14, which makes it possible for the water under pressure to enter the pressure distribution chamber 13 as homogeneously as possible in the direction of extent of the nozzle beam 1. By arranging the bluff body 20 centrally in the pressure distribution chamber 13, the water flow under pressure is likewise brought most homogeneously and preferably less swirlingly into the slits 19 bordering the pressure distribution chamber 13, so that the water flow acts substantially uniformly on the nozzle plate 17 over the entire length of the nozzle plate 17.
The invention is not limited in its implementation to the preferred embodiments mentioned above. Rather, variants are conceivable which make use of the presented solution even if implemented substantially in different types. The features and/or advantages, including structural details or spatial arrangements, which can be derived from the claims, the description and the drawings, can be regarded as essential both in themselves and in various combinations.
