Abstract

Catcher for fluid jet-cutting devices which has an insert (18) which is provided with deflection bodies (20) which cover the screening floor (19) of the said insert (18), the said catcher being filled up to the inlet gap (28) with service water. It is built into a service water circuit in the case of which service water is pumped by a pump (12) from a multi-chamber settling basin (9) via a flexible tube (14) into a free space (21) which is situated between the screen floor (19) and the catcher floor (16). The outlet (17), through which the catcher (4) is drained into a tunnel (5) which is situated on the floor (31) of a trough (2), is passed through by less service water than is delivered by the pump (12) so that the service water fills the catcher (4) up to an overflow (25). The overflow (25) leads to pocket-like chambers (34) which extend over the entire sides (24) and have a floor strip (35) which drops sharply from the inflow to the outflow side of the catcher (4) and terminates immediately in front of the end face (36) of the chamber (34). The service water with sludge which runs into the trough (2) is pumped into the multi-chamber settling basin (9) by means of a sludge pump (8). Above the catcher (4) there is situated a grating which acts as a supporting table, covers the trough and is made of strips of material, against the underside of which there rest sealing strips (29) which take the form of brush strips. The bed of water situated above the gap (28) between the sealing strips (29) is made to splash up by the impact of a jet of fluid and fills the grating chamber situated above. <IMAGE>

Description

Die Erfindung betrifft einen flächenüberstreichenden Liniencatcher für eine Fluidstrahlschneidanlage mit einem Wasserbett und einer Abrasivmittelausschwemmung.The invention relates to an area-covering line catcher for a fluid jet cutting system with a water bed and an abrasive washout.

Allgemein ist es bekannt, den Reststrahl einer Fluidstrahlschneidanlage in einem wassergefüllten Catcher von entsprechender Tiefe aufzufangen. Es werden dazu Liniencatcher verwendet, deren Bauhöhe durch eine auf dem Boden des Catchers befindliche Prallplatte verringert wird. Über diese Prallplatte fließt ein Wasserstrom, der das Abrasivmittel und Schneidgutreste aus dem Catcher auswäscht (EP 0270 364).It is generally known to catch the residual jet of a fluid jet cutting system in a water-filled catcher of the appropriate depth. Line catchers are used for this purpose, the overall height of which is reduced by a baffle plate located on the bottom of the catcher. A flow of water flows through this baffle plate, which washes the abrasive and cutting material residues out of the catcher (EP 0270 364).

Es sind auch kugelgefüllte Trockencatcher bekannt, bei denen der Reststrahl Kugeln in Bewegung setzt und das Fluid durch eine Bodenöffnung abläuft. Der Ablauf kann auch an der Seite des Catchers angebracht sein, so daß sich der Catcher mit Fluid bis zum Auslauf füllt. Für das Auffangen eines mit Abrasivmittel arbeitenden Fluidstrahls scheint dieser Catcher wenig geeignet (EP 020 8038).Ball-filled dry catchers are also known, in which the residual jet sets balls in motion and the fluid runs off through a bottom opening. The drain can also be attached to the side of the catcher so that the catcher fills with fluid up to the outlet. This catcher appears to be unsuitable for collecting a fluid jet working with an abrasive (EP 020 8038).

Aus EP 0319143 ist ein Liniencatcher bekannt, der als flexibler Netzschlauch U-förmig unter dem Schneidsystem angebracht ist und mit Füllkörpern, die gekühlt werden, gefüllt ist.A line catcher is known from EP 0319143, which is attached as a flexible mesh tube U-shaped under the cutting system and is filled with packing elements that are cooled.

Flächencatcher in Trogform sind auch bekannt. Über dem eine Prallplatte tragenden Boden des Troges ist ein Bett aus Wabenmaterial aufgebaut, unter dem geneigte Ablenkplatten zur Reststrahlablenkung bzw. Zerstreuung des Strahls angebracht sind. Es handelt sich um einen Trockencatcher, der ebenfalls wenig geeignet für die Arbeit mit einem mit Abrasivmittel beaufschlagten Fluidstrahl erscheint (OS 28 13489).Trough-shaped area catchers are also known. A bed of honeycomb material is built above the bottom of the trough carrying a baffle plate, under which inclined baffle plates are attached for deflecting the residual beam or scattering the beam. It is a dry catcher, which also appears to be unsuitable for working with a fluid jet loaded with an abrasive (OS 28 13489).

Der Erfindung liegt die Aufgabe zugrunde, einen in einem Brauchwasserkreislauf eingebundenen, flächenüberstreichenden Liniencatcher mit Brauchwasser zu füllen und zu spülen. Er soll in einem Trog in Längsrichtung beweglich sein und von Abrasivmittel und Schneidgutresten entsorgt werden.The object of the invention is to fill and rinse a line catcher which is integrated in a process water circuit and covers the area with process water. It should be movable in a longitudinal direction in a trough and disposed of by abrasives and cutting material residues.

Zur Lösung der Aufgabe ist ein Behälter als Liniencatcher in einem Trog aufgehängt. Der Trog befindet sich unter einem Maschinentisch. Der Maschinentisch besteht aus senkrecht stehenden, sich kreuzenden und dabei Kammern bildenden Materialstreifen. Der Behälter reicht über die Breite des Troges und ist in dessen Längsrichtung verfahrbar. Im Behälter befindet sich ein Einsatz, der einen Siebboden hat, der mit Prallkörpern abgedeckt ist. Der Einsatz läßt unter sich im Behälter eine Spülrinne frei. Die obere Öffnung des Einsatzes besteht aus als Schwallbrecher wirkenden abgekröpften Führungen, die zwischen sich einen Spalt als Zugang zum Inneren des Einsatzes frei lassen. Die Führungen tragen Dichtungsstreifen, die in Längsrichtung des Behälters verlaufen und an der Unterseite des Maschinentisches anliegen. Die Dichtungsstreifen können von Bürstenleisten gebildet werden. An einer Stirnseite des Behälters ist über einen Schlauchanschluß ein auf der Außenseite des Troges ablegbarer flexibler Schlauch zur Brauchwasserzuführung angeschlossen. Am Boden, neben der gegenüberliegenden Stirnseite des Behälters, befindet sich ein Ausfluß, der den Behälter in eine am Boden des Troges befindliche Rinne entwässert. Dem Behälter wird mehr Brauchwasser zugeführt, als durch den Ausfluß abfließen kann. Zwischen jeder Seitenwand des Einsatzes und der des Behälters befindet sich ein Steigschacht. An der Außenseite der Seitenwände des Behälters sind über die gesamte Seitenwand reichende taschenförmige Kammern angebracht. Der Bodenstreifen der Kammern ist stark zur Rinne im Trogboden hin geneigt. Der Bodenstreifen endet vor der Stirnwand der Kammer und läßt ein Abflußloch über der Rinne frei. Die Rinne ist wie der gesamte Boden des Troges zu einer Sammelmulde hin geneigt. Aus der Sammelmulde wird das mit Abrasivmittel und Schneidgutresten belastete Brauchwasser durch eine Schlammpumpe abgesaugt. Das Brauchwasser wird in ein neben dem Trog befindliches Mehrkammerabsetzbecken gefördert, dort gereinigt und wieder den Brauchwasserkreislauf schließend dem Behälter zugeführt.To accomplish the task, a container is suspended in a trough as a line catcher. The trough is located under a machine table. The machine table consists of vertical strips of material that intersect and form chambers. The container extends across the width of the trough and can be moved in its longitudinal direction. There is an insert in the container which has a sieve bottom which is covered with impact bodies. The insert leaves a flush channel underneath in the container. The upper opening of the insert consists of angled guides which act as a surge breaker and leave a gap between them for access to the interior of the insert. The guides carry sealing strips that run in the longitudinal direction of the container and lie against the underside of the machine table. The sealing strips can be formed by brush strips. At one end of the container, a flexible hose, which can be placed on the outside of the trough, is connected to the process water supply via a hose connection. On the bottom, next to the opposite end of the container, there is a Outflow, which drains the container into a trough located at the bottom of the trough. More process water is supplied to the container than can flow through the outflow. There is a riser between each side wall of the insert and that of the container. On the outside of the side walls of the container, pocket-shaped chambers extending over the entire side wall are attached. The bottom strip of the chambers is strongly inclined towards the trough in the trough bottom. The bottom strip ends in front of the front wall of the chamber and leaves a drain hole above the channel. The gutter, like the entire bottom of the trough, is inclined towards a collecting trough. The process water contaminated with abrasive and cutting material residues is sucked out of the collection trough by a slurry pump. The process water is pumped into a multi-chamber settling tank located next to the trough, cleaned there and the process water circuit is closed and returned to the tank.

A trough 2 is located in a machine substructure 1. A container 3 of a line catcher 4 is stored in the trough 2. The line catcher 4 bridges the trough 2 and runs in the longitudinal direction on the edge 30 of the trough 2 designed as rails. In the trough bottom 1 there is a groove 5 which is inclined towards a collecting trough 6. In the collecting trough 6, the inlet of a suction hose 7 of a slurry pump 8 is inserted.

Die Schlammpumpe 8 pumpt das belastete Brauchwasser aus der Sammelmulde 6 in ein Mehrkammerabsatzbecken 9. Im Mehrkammerabsatzbecken 9 befindet sich ein Förderband 10, das den sich absetzenden Schlamm aus Abrasivmittel und Schneidgutresten aus dem Mehrkammerabsatzbecken 9 fördert. In das Mehrkammerabsatzbecken 9 ragt ein Ansaugstutzen 11 einer Pumpe 12. Vor den Ansaugstutzen 11 befindet sich ein hier nicht dargestellter Filter. An die Pumpe 12 ist ein flexibler Schlauch 14 angeschlossen, der auf einer Ablage 13 neben dem Trog 2 liegt. An den Schlauch 14 ist ein als Siphon ausgebildeter Zufluß 32 angeschlossen. Der Zufluß 32 ist durch einen Spalt 33 von außen. in den Trog 2 geführt. Er ist an einer Stirnwand 15 des Behälters 3 dicht über dessen Boden 16 angeschlossen. Im Boden 16 des Behälters 3 ist neben der gegenüberliegenden Stirnwand ein Ausfluß 17 angebracht, dessen Durchlaßöffnung einstellbar ist. Der Ausfluß 17 entwässert den Behälter 3 in die Rinne 5. Im Behälter 3 befindet sich ein Einsatz 18. Sein Siebboden 19 ist mit Prallkörpern 20 bedeckt. Zwischen dem Siebboden 19 und dem Boden 16 des Behälters 3 befindet sich ein vom Brauchwasser durchströmter Freiraum 21. An diesen Freiraum 21 schließen sich Steigschächte 22 an. Die Steigschächte 22 werden durch die Seitenwände 23 des Einsatzes 18 und den Seitenwänden 24 des Behälters 3 gebildet. Sie führen zu einem Überlauf 25. In der oberen Öffnung 26 des Einsatzes 18 sind Führungen 27 angebracht. Sie lassen zwischen sich einen Spalt 28 frei. Auf den Führungen 27 sind Dichtungsstreifen 29 befestigt. Diese Dichtungsstreifen 29 können Bürstenleisten mit nach oben stehenden Borsten sein. Die Bürstenleisten können den Überlauf 25 umrahmen. Die Dichtungsstreifen 29 liegen an der Unterseite des nicht dargestellten Maschinentisches an. Der Maschinentisch besteht aus einem Gitterrost. Der Gitterrost besteht aus senkrechtstehenden, sich kreuzenden Materialstreifen. Auf jeder Außenfläche der Seitenwände 24 ist eine taschenförmige Kammer 34 aufgesetzt. Die Kammer 34 ist nach oben offen und folgt auf den Überlauf 25. Der Bodenstreifen 35 der Kammer 34 senkt sich von der Zuflußseite 15 zur Abflußseite des Liniencatchers 4 hin ab. Er endet vor der Stirnwand 36 der Kammer 34 und läßt ein Abflußloch 37 frei. Dieses Abflußloch 37 befindet sich neben dem Ausfluß 17 über der Rinne 5.The sludge pump 8 pumps the contaminated service water from the collecting trough 6 into a multi-chamber sales basin 9. In the multi-chamber sales basin 9 there is a conveyor belt 10 which conveys the sludge from abrasive and cutting material residues from the multi-chamber sales basin 9. An intake port 11 of a pump 12 projects into the multi-chamber sales basin 9. A filter (not shown here) is located in front of the intake port 11. A flexible hose 14 is connected to the pump 12 and lies on a shelf 13 next to the trough 2. An inflow 32 designed as a siphon is connected to the hose 14. The inflow 32 is through a gap 33 from the outside. led into the trough 2. It is connected to an end wall 15 of the container 3 close to the bottom 16 thereof. In the bottom 16 of the container 3, an outlet 17 is attached next to the opposite end wall, the passage opening is adjustable. The outflow 17 drains the container 3 into the channel 5. There is an insert 18 in the container 3. Its sieve bottom 19 is covered with impact bodies 20. Between the sieve bottom 19 and the bottom 16 of the container 3 there is a free space 21 through which the process water flows. Rising shafts 22 adjoin this free space 21. The risers 22 are formed by the side walls 23 of the insert 18 and the side walls 24 of the container 3. They lead to an overflow 25. In the upper opening 26 of the insert 18 guides 27 are attached. They leave a gap 28 between them. Sealing strips 29 are fastened on the guides 27. These sealing strips 29 can be brush strips with upstanding bristles. The brush strips can frame the overflow 25. The sealing strips 29 rest on the underside of the machine table, not shown. The machine table consists of a grating. The grating consists of vertical, intersecting strips of material. A pocket-shaped chamber 34 is placed on each outer surface of the side walls 24. The chamber 34 is open at the top and follows the overflow 25. The bottom strip 35 of the chamber 34 lowers from the inflow side 15 to the outflow side of the line catcher 4. It ends in front of the end wall 36 of the chamber 34 and leaves a drain hole 37 free. This drain hole 37 is located next to the outlet 17 above the channel 5.

Durch den Zufluß 32 wird der Linincatcher 4 mit Brauchwasser versorgt. Dabei wird ihm mehr Brauchwasser zugeführt, als durch den einstellbaren Ausfluß 17 abfließen kann. Der Liniencatcher 4 füllt sich bis zum Überlauf 25. Das überschüssige Brauchwasser fließt über den Überlauf 25 in die Kammern 34. Durch die Neigung der Bodenstreifen 35 wird es zum Abflußloch 37 geleitet. Es fließt zusammen mit dem den Liniencatcher durchspülenden, aus dem Ausfluß 17 austretenden Brauchwasser in die Rinne 5. In der Rinne 5 herrscht eine Strömung, die ein Absetzen von Abrasivmittel oder Werkstoffresten verhindert.The line catcher 4 is supplied with process water by the inflow 32. It is supplied with more process water than can flow through the adjustable outlet 17. The line catcher 4 fills up to the overflow 25. The excess service water flows via the overflow 25 into the chambers 34. The inclination of the bottom strips 35 leads it to the drain hole 37. It flows into the channel 5 together with the process water flushing through the line catcher and emerging from the outlet 17. In the channel 5 there is a flow which prevents abrasive agent or material residues from settling.

Der mit Abrasivmittel beaufschlagte Schneidstrahl tritt in den wassergefüllten Einsatz 18 durch den Spalt 28 ein. Er wird im Brauchwasser und den Prallkörpern 20 entspannt. Beim Eintreten des Schneidstrahls wallt das Brauchwasser auf. Die Dichtungsstreifen 29 verhindern, daß das aufwallende Brauchwasser seitlich in den Überlauf 25 abfließt. Das aufwallende Brauchwasser füllt nun die über der Eintreffstelle des Schneidstrahls liegende Kammer des Gitterrostes. Dadurch wird der vom aus dem Schneidgut austretenden Schneidstrahl verursachte Geräuschpegel stark gemindert. Das Abrasivmittel fällt durch den Siebboden 19 in den brauchwasserdurchströmten Freiraum 21. Durch den Brauchwasserstrom wird es aus dem Liniencatcher 4 in die Rinne 5 gespült und weiter von dort aus der Sammelmulde 6 mit der Schlammpumpe 8 in das Mehrkammerabsatzbecken 9 gefördert.The cutting jet acted upon by abrasive agent enters the water-filled insert 18 through the gap 28. It is relaxed in the process water and the impact bodies 20. When the cutting jet enters the process water rises. The sealing strips 29 prevent the inflowing service water from flowing laterally into the overflow 25. The surge of process water now fills the grating chamber above the point of arrival of the cutting jet. The noise level caused by the cutting jet emerging from the material to be cut is thereby greatly reduced. The abrasive falls through the sieve tray 19 into the space 21 through which the process water flows, and is rinsed out of the line catcher 4 into the channel 5 by the process water flow and from there it is conveyed from the collecting trough 6 with the sludge pump 8 into the multi-chamber sales basin 9.
