Definitions

  • the present invention refers to a device for alternately charging and cleaning of tubes and hoses, said device is equipped with flexible organs for adaptation of the length and form of said tube/hose.
  • the object of the present invention is to achieve a device of the type mentioned above which allows simultaneously cleaning of tubes/hoses, said device comprising washing heads, service unit with tank, pump and filtrated compressed air is arranged so that two washing stations can be used independent from each other.
  • the device is arranged so that while one station is performing a cleaning operation the other station is unloaded and reloaded.
  • Fig 1 shows a schematic side view of an example, which includes two workstations with pair arrangement of washing heads,
  • Fig 2 shows a view of an exemplified device from fig 1 together with an example of the movable flexibility of the washing heads and
  • Fig 3 shows a flow scheme of the cleaning process.
  • a physical unit for alternated loading/unloading and cleaning operation comprising flexible means 3 ' - 6 ' for adapting of various lengths and forms of the tube/hose.
  • the physical unit consists of a frame wherein a tank 12 is attached together with purifying devices for liquid and compressed air and a liquid/air separation cyclone 1 1.
  • On the framework of the tank 12 two movable arms 20 are attached, on which means 22 are telescopic attached, these means are holding washing heads 3-6 with exchangeable clamping means 3 ', 6' for tubes and hoses 7, 8 of various length and forms.
  • the means 3', 6' are movable attached with means to enable fixation of washing heads 3 and 6 in various positions.
  • On the arm 20 an individual, further movable arm 21 is also fixed, which also comprises washing heads 4 and 5 respectively, with clamping organs 4', 5' for tubes and hoses 7, 8 which equally can be fixt in various positions.
  • Fig. 3 shows the schematic flow of the process in closer details.
  • the process is divided in tree steps: Step one concerns the liquid flow from tank 12 by means of a pump 13 through a back valve 17 and a 2-way valve 16 to a choice between, on one hand, washing head 3 in a first pair of washing heads 3,4 or a washing head 5 in a second pair of washing heads 5,6.
  • This choice of direction is set in a programmable control unit in order to direct the flow trough valve 1 or 2.
  • the liquid flow passes trough the tube/hose 7 to the second washing head 4 in the first pair 3,4 and the second washing head 6 in the second pair 5,6, alternatively between the first washing head 3 in the first pair 3,4 and the second washing head 6 in the second pair 5,6 via the tube/hose 8 and the first washing head 5 in the second pair 5,6 and the second washing head 4 in the first pair 3,4, respectively, and from there further back to the tank 12 via dirt filters 19 and 20, respectively and through back valves 9 and 10, respectively, and from there via a cyclone 11 for separation of liquid and air, back to the tank 12.
  • the steps 2 and 3 are a combination of liquid evacuation and dry blowing phase with compressed air, whereby as the first step the remaining liquid in the tube/hose is evacuated with boosted compressed air P through a back valve 15 respective 14, next step is a blowing phase with compressed air from the net without the booster function.
  • oil can be injected in the compressed air stream, which give an efficient rust protection in the tube/hose application.
  • the oil injection takes place at the end of the clean blowing phase in the second step.
  • a valve 18 the remains of liquid in the circuit system will be evacuated back to tank 12 together with the normal evacuation through the washing heads 3 - 6.
  • the invention is about the physical and technical solution, which optimises the function within the frame of a compact unit shearing control and performance.

Abstract

La présente invention concerne un dispositif permettant le chargement /déchargement et le nettoyage alternés de tubes et de tuyaux, comprenant un organe flexible (20-22) destiné à ajuster les diverses longueurs et formes des tubes/tuyaux (7, 8), cet organe étant équipé de têtes de lavage (3-6) et de dispositifs de fixation (3'-6') attachés à celui-ci, et ces dispositifs étant placés par paires et pouvant se régler au dimensions de différents raccords de tube/tuyaux. Le processus de nettoyage est effectué de façon alternée entre une première (3, 4) et une seconde (5, 6) paire de têtes de nettoyage, et enfin, par ailleurs, entre la première tête de nettoyage (3) de la première paire (3, 4) et la seconde tête de nettoyage (6) de la seconde paire (5, 6) et entre la seconde tête de nettoyage (4) de la première paire (3, 4) et la première tête de nettoyage (5) de la seconde paire (5, 6). Toutes ces têtes de nettoyage sont couplées ensemble avec une même unité physique, sur laquelle des programmes individuels peuvent être installés pour des circuits de nettoyage respectifs.
