Definitions
- the invention relates to a self-cleaning nozzle for spraying a fluid with a nozzle housing and arranged therein, a multi-part nozzle head, which includes a flow channel with an outlet opening for the fluid.
- the nozzle head is slidably mounted in the nozzle housing and pressed by the fluid pressure against the force of a spring in the working position relative to a spray head.
- the spring pushes the nozzle head
- Nozzle head opposite to the flow direction away from the spray head, which leads to an enlargement of the outlet opening and to the washing away of foreign substances from this area.
- the object of the invention is therefore to develop a self-cleaning nozzle, which is as reliable as possible and associated with the lowest possible production cost.
- the object has been achieved in that the nozzle head has at least one fixed and at least one displaceably mounted head element, each forming a portion of the outlet opening, wherein the displaceable head element during normal operation of the fluid pressure against a in Flow direction of the fluid lying stop and during self-cleaning at reduced fluid pressure by a spring against the flow direction is pressed.
- Outlet opening forms.
- the size and shape of this section but also the shape of the flow channel affect the extent of the enlargement and thus the quality of self-cleaning significantly.
- the displaceable head element should be pressed during self-cleaning by the spring against a lying opposite to the direction of flow stop.
- Reduction in the direction of the outlet also increases the degree of enlargement of the outlet opening when pushing back the head element during self-cleaning.
- the construction can be further simplified in that the stops are formed by the nozzle housing and / or the spring in one
- a parting plane between the two head elements should be parallel or inclined to the flow direction.
- the nozzle head is formed in two parts.
- the dividing plane should run between the two header elements for simplicity through the middle of the flow channel, so that the displaceable head element has a sufficient size for influencing the outlet opening during self-cleaning.
- the nozzle can be further improved by the fact that the fixed head element projects beyond the outlet opening with a jet guide and changes the fluid jet emerging from the outlet opening with respect to the jet direction and / or the jet shape. This can be used in particular for a laterally inclined radiation of the fluid jet.
- the outlet opening of the nozzle head should preferably be releasably secured in a nozzle housing
- the spray head may have only one or more channels, which distribute the fluid on several sides, preferably on all sides.
- FIG. 1 shows a schematic longitudinal section through a nozzle in the operating position
- FIG. 2 shows a cross section according to FIG. 1 and FIG
- Figure 3 a longitudinal section through another nozzle during self-cleaning.
- the nozzle is due to its high reliability and high degree of self-cleaning especially for spraying process water of the same but also changing qualities, especially in proportions of fiber materials, as they are needed for the production of fibrous webs.
- the nozzle is essentially a
- Nozzle housing 1 is formed, which receives the two-part nozzle head.
- the nozzle head itself forms the flow channel 4, the fluid to the
- Outlet opening 5 promotes.
- the flow channel 4 has a circular
- the two parts of the nozzle head are formed by a fixed 2 and a parallel to the flow direction 6 of the fluid slidably mounted 3 head element.
- the dividing plane 1 1 extends between the two head elements 2, 3 essentially through the middle of the flow channel 4 parallel to the flow direction 6.
- both head elements 2, 3 form an approximately equal section of the outlet opening 5.
- the fixed head element 2 and the nozzle housing 1 are made in one piece.
- the force acting on the displaceable head element 3 fluid pressure causes a pressing of this head element 3 against the force of a spring 8 against a lying in the flow direction 6 stop 7 of the nozzle housing. 1
- the fluid pressure exposed In order to generate a sufficient force for this purpose, the counter to the flow direction 6 facing, the fluid pressure exposed
- Attack surface of the displaceable head element 3 to be sufficiently large.
- the displaceable head element 3 is sealed relative to the nozzle housing 1, so that the fluid can generate a corresponding force.
- the displaceable head element 3 at the, the outlet opening 5 opposite end has a circular, aligned perpendicular to the flow direction 6 and parallel to the flow direction 6 in the nozzle housing 1 slidably mounted stabilizing ring 16. This stabilizing ring 16 forms the beginning of
- Flow channel 4 and has to seal against the nozzle housing 1, a sealing bead 14, which projects into a recess 15 of the nozzle housing 1.
- the recess 15 allows the sliding of the sealing bead 14 between
- the spring 8 is in this case in a recess 10 of the displaceable
- Head element 3 wherein the counter to the flow direction 6 facing end of the spring 8 in the recess 10 of the head element 3 and the opposite end of the nozzle housing 1 is supported.
- the fixed head element 2 can also project beyond the outlet opening 5 with a jet guide 12.
- this beam guide 12 is intended to deflect the fluid jet emerging from the outlet opening 5 and / or to change its shape.
- a spray head 13 in each case releasably fastened to the nozzle housing 1, into which the outlet opening 5 of the nozzle head opens.
- the releasable attachment can be done for example via screw or a clip closure and thus allows easy replacement of a spray head 13 in case of wear or changing requirements on the shape of the fluid jet.
- the spray head 13 according to Figure 1 the fluid also multi-sided, in particular distribute on all sides.
- Head element 3 and the spray head 13 made of plastic. In addition, the facilitated
