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 eine Fangeinrichtung für Fluidstrahlschneidanlagen mit einem in einem Brauchwasserkreislauf zur Abrasivmittelausschwemmung eingebundenen, in einem Trog befindlichen Einsatzbehälter nach dem Oberbegriff des Anspruchs 1.The invention relates to a catching device for fluid jet cutting systems with an insert container, which is integrated in a process water circuit for the abrasive discharge and is located in a trough, according to the preamble of claim 1.

Allgemein ist es bekannt, den Reststrahl einer Fluidstrahlschneidanlage in einem wassergefüllten Catcher von entsprechender Tiefe aufzufangen. Es wurden 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 270364).
Es sind auch kugelgefüllte Trockencatcher bekannt, bei denen der eindringende Reststrahl die 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 0208038)
Aus EP 0319143 ist ein Liniencatcher gemäß dem Oberbegriff des Anspruchs 1 bekannt, der als flexibler Netzschlauch U-förmig unter dem Schneidsystem angebracht ist und mit Füllkörpern, die gekühlt werden, gefüllt ist.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 were used for this purpose, the overall height of which is reduced by a baffle plate located on the bottom of the catcher. A water flow flows through this baffle plate, which washes the abrasive and cutting material residues out of the catcher (EP 270364).
Ball-filled dry catchers are also known, in which the penetrating residual jet sets the 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 0208038)
From EP 0319143 a line catcher according to the preamble of claim 1 is known, which is attached as a flexible mesh tube U-shaped under the cutting system and is filled with packing elements that are cooled.

Aus dem US-Patent 51 27 199 ist eine trogförmige, sich über die ganze Arbeitsfläche eines in zwei Richtungen bewegbaren Wasserstrahlschneidkopfs erstreckende Fangeinrichtung für den Restwasserschneidstrahl bekannt, die von Brauchwasser durchströmt wird. Der Boden ist mit Verschleißplatten geschützt. Unter den Verschleißplatten strömt Spülwasser die Schneidgutreste und Abrasivmittel von der Bodenfläche des Troges. Ein Gitterrost dient als Maschinentisch und deckt den Trog oben ab. Über die Verschleißplatten und durch Löcher in ihnen strömt Brauchwasser von einem Raum über den Verschleißplatten in den Raum zwischen Verschleißplatten und Trogboden.From US Patent 51 27 199 a trough-shaped, over the entire working surface of a water jet cutting head movable in two directions catching device for the residual water cutting jet is known, which is flowed through by domestic water. The floor is protected with wear plates. Rinsing water flows under the wear plates of the material to be cut and abrasive from the bottom surface of the trough. A grating serves as a machine table and covers the trough at the top. Service water flows from a room above the wear plates into the space between the wear plates and the trough bottom through the wear plates and through holes in them.

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 angebracht sind. Es handelt sich um einen Trockencatcher, der ebenfalls wenig geeignet für die Arbeit mit einem mit Abrasivmittel beaufschlagten Fluidstrahl erscheint (05 2813498).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 residual radiation or scattering. It is a dry catcher, which also appears to be unsuitable for working with an abrasive fluid jet (05 2813498).

Der Erfindung liegt die Aufgabe zugrunde, einen in einen Brauchwasserkreislauf eingebundenen, in einem Trog verfahrbaren Einsatzbehälter mit Brauchwasser zu füllen und zur Entsorgung von Abrasivmittel und Schneidgutresten zu spülen.The object of the invention is to fill an insert container, which is integrated in a process water circuit and can be moved in a trough, with process water and to rinse it for the disposal of abrasive agents and material residues.

Zur Lösung der Aufgabe ist die Fangeinrichtung durch die Merkmale des Anspruchs 1 gekennzeichnet. Weiter vorteilhafte Ausgestaltungen der Fangeinrichtung sind Gegenstand weiterer Unteransprüche.To achieve the object, the catching device is characterized by the features of claim 1. Further advantageous embodiments of the catching device are the subject of further subclaims.

In einem Maschinenunterbau 1 befindet sich ein rechteckiger Trog 2. In dem Trog 2 ist ein Einsatzbehälter 3 beweglich gelagert. Der Einsatzbehälter 3 überbrückt den Trog 2 und läuft auf dem als Schienen ausgebildeten langen Rand 30 des Troges 2. In dem Trogboden 31 befindet sich eine Rinne 5, die zu einer Sammelmulde 6 hin geneigt ist. In die Sammelmulde 6 ist der Einlaß eines Saugschlauches 7 einer Schlammpumpe 8 eingelegt.A rectangular trough 2 is located in a machine substructure 1. An insert container 3 is movably mounted in the trough 2. The insert container 3 bridges the trough 2 and runs on the long edge 30 of the trough 2 designed as rails. In the trough bottom 31 there is a channel 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 dem Ansaugstutzen 11 befindet sich ein hier nicht dargestelltes 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. Der Zufluß 32 ist an einer Stirnwand 15 des Einsatzbehälters 3 dicht über dessen Boden 16 angeschlossen. Im Boden 16 des Einsatzbehälters 3 ist neben der der Stirnwand 15 gegenüberliegenden Stirnwand ein Ausfluß 17 angebracht, dessen Durchlaßöffnung in der Größe einstellbar ist. Der Ausfluß 17 entwässert den Einsatzbehälter 3 in die Rinne 5. Im Einsatzbehälter 3 befindet sich ein Einsatz 18. Sein Siebboden 19 ist mit Prallkörpern 20 bedeckt. Zwischen dem Siebboden 19 und dem Boden 16 des Einsatzbehälters 3 befindet sich ein vom Brauchwasser durchströmter Freiraum 21. An diesen Freiraum 21 schließen sich Steigschächte 22 an. Die Steigschächte 22 werden durch die Seitenwänden 23 des Einsatzes 18 und den Seitenwänden 24 des Einsatzbehälters 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. Das Gitterrost besteht aus senkrechtstehenden, sich kreuzenden Material streifen. Auf jeder Außenfläche der Seitenwände 24 des Einsatzbehälters 3 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 Zuflußstirnseite 15 zur Abflußstirnseite des Einsatzbehälters 3 hin ab und endet vor der Stirnwand 36 der Kammer 34. Damit bleibt ein Abflußloch 37 neben dem Ausfluß 17 über der Rinne 5 frei.The sludge pump 8 pumps the polluted 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 carries the sludge which settles out promotes 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 guided through a gap 33 from the outside into the trough 2. The inflow 32 is connected to an end wall 15 of the insert container 3 close to the bottom 16 thereof. In the bottom 16 of the insert container 3, an outlet 17 is attached in addition to the end wall opposite the end wall 15, the outlet opening of which is adjustable in size. The outflow 17 drains the insert container 3 into the channel 5. An insert 18 is located in the insert container 3. Its sieve bottom 19 is covered with impact bodies 20. Between the sieve bottom 19 and the bottom 16 of the insert container 3 there is a free space 21 through which the process water flows. Rising shafts 22 are connected to 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 insert 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 of the insert container 3. 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 end 15 to the outflow end of the insert container 3 and ends in front of the end wall 36 of the chamber 34. This leaves a drain hole 37 next to the Outflow 17 over the channel 5 free.

Durch den Zufluß 32 wird der Einsatzbehälter 3 mit Brauchwasser versorgt. Dabei wird ihm mehr Brauchwasser zugeführt, als durch den einstellbaren Ausfluß 17 abfließen kann. Der Einsatzbehälter 3 füllt sich zum Überlaufen über den Überlauf 25. Das überlaufende 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 Einsatzbehälter 3 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 feed tank 3 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 insert container 3 fills to overflow via the overflow 25. The overflowing 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 out of the insert container 3 and emerging from the outlet 17. A channel prevails in the channel 5, which prevents abrasive agents 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 vom es aus dem Einsatzbehälter 3 in die Rinne 5 des Troges 2 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 free space 21 through which the process water flows. The process water flows from the insert container 3 into the channel 5 of the trough 2 and from there it is conveyed from the collecting trough 6 with the sludge pump 8 into the multi-chamber sales basin 9.
