Abstract:
This invention concerns a machine (50) for removing wrap-around labels (2) or shrink-wraps from bottles or similar devices (1). To achieve a simple and compact embodiment of such a machine (50), the cutting blades (62) are located in the intake area of the machine (50).
Abstract:
The present invention relates to a method for cleaning a container (30) and conduits (32, 33, 36) associated with said container by adding a cleaning solvent to the container and circulating said solvent through said conduits back to said container. In accordance with the invention the cleaning solvent additionally is forced intermittently through a filter unit (1) containing an absorbent material, preferably active carbon (3), and then is allowed to flow through said conduits to said container, said container and conduits thus intermittently being flushed with clean solvent. The container may be a reaction vessel for chemical processes.
Abstract:
A process and device are disclosed for automatically unfolding plastic trays to be cleaned having side walls that may be folded onto the bottom of the tray and that are snap-locked in the completely unfolded state at the entrance area into a washing installation through which the trays are automatically transported. Pairs of opposite side walls are unfolded downwards by the force of gravity and water pressure, and supported by a device that essentially consists of a pyramid-shaped body made of metal guiding plates and hook-shaped fingers, whereas the bottom of the tray faces upwards.
Abstract:
The invention relates to an equipment for cleaning of different objects such as tanks, pipeline systems etc. in a plant for treatment of food, in which equipment there is an arrangement comprising means for conveying a liquid. This means is arranged to convey a variable controlled amount of liquid with a variable controlled flow rate. In series with this means there is a volume and/or flow rate metering means and a control means connected to the volume and/or flow rate metering means and receiving signals from the same. The control means is arranged to actuate the means for conveying liquid in dependence of this signal such that the desired amount of liquid is conveyed with a desired flow rate. The conveying means mentioned above and the volume and/or flow rate metering means are arranged in a conduit for supplying rinsing or cleaning liquid to one or several objects which are to be cleaned.
Abstract:
A method and apparatus for cleaning the interior of a container (46) or one or more objects (48) suspended therein comprising generating a fluid vapor column by forming an air column having a direction of air flow in a vaporization chamber (20). The air column is passed through a heating means (40), so as to heat the air, and then the cleaning fluid from supply tank (12) is injected into the air column against the direction of air flow. The fluid vapor column is then brought into contact with the interior of the container (46) so that the vapor condenses on the interior of the container (46) or on objects (48) suspended therein.
Abstract:
A washing system for oil tanks comprises a washer head (16) for mounting within an oil tank, and a conduit (22) for delivering fluid under pressure to nozzles (26) on the washer head which are movable so as to distribute the fluid emerging under pressure from the nozzles over the internal walls of the tank. A cam and follower device (27, 32) is arranged to sense the continuing operative movement of the nozzles, and to transmit to the exterior of the tank, through a fluid filled conduit (33), pressure pulse signals indicative of said continuing movement, means (38) being provided to monitor the signals and produce an output in response thereto.
Abstract:
Cleaning device, especially for cleaning of tanks, comprising a pipeline (3) suspended from the top of the tank, a cleaning head (1) comprising a number of nozzles being secured to the pipe and comprising a plurality of nozzles rotating about a horizontal axis when the head as such is rotating around a vertical axis by mechanical meshing gears and where the cleaning fluid is supplied to the nozzles to the pipe, where the pipe (3) being suspended in a drive means (2) which is rotating a shaft (4) arranged in interior of the pipe, the rotation of the shaft being transferred to the cleaning head to rotate the cleaning head about the vertical axis and thereby rotating the nozzles about the horizontal axis, the cleaning head comprising the nozzles having a ball shape without protruding parts and that further pipe segments having a cleaning head arranged on the lower end, may be fixed to the lowermost cleaning head thereby connecting the shafts (4) in the interior of the pipe segments for rotating all cleaning heads and nozzles.
Abstract:
An apparatus for cleaning the interior surfaces of a vessel (1) which includes a cleaning head (2) supported and guided into the vessel by a rigid air shaft (3). The cleaning head (2) is supplied with a process fluid and directs and removes the process fluid from a cleaning zone located on the interior surface of the vessel (1). The process fluid is heated by a heat exchanger hose assembly (5) that is connected to the air shaft (3). The apparatus utilizes turbulent fluid flow, thermal shock, ultrasonic vibration and/or piezoelectric vibration to dislodge particulates from the inner surfaces of the vessel. The apparatus is useful for cleaning chemical vapor deposition reactors and other similar vessels.
Abstract:
A method and apparatus for cleaning the interior of storage tanks of the type used for storing large volumes of liquids, such as crude oil, wherein hydrocarbon sludge accumulates with the passage of time, such apparatus comprising a hollow housing (310), liquid agitation means including a plurality of nozzled outlet jets laterally rotatably mounted on the housing in fluid communication with the hollow interior thereof, connecting means comprising an independently rotatable tubular casing (382) rotatably mounted on the housing in fluid communication with the interior thereof, the tubular casing having a kelley (400) mounted therein and being operatively connected with the nozzled outlet jets, and multi-joint support pipe (500) means rotatably jointed to the connecting means in fluid communication with the interior of the tubular casing. With this construction, an appropriate pump means may be provided for forcing a liquid, such as crude oil through the multi-joint support pipe means into the hollow housing and out of the hollow housing through the nozzled outlet jets and indexing power means may suitably be provided and operatively rotatably connected to the laterally rotatable outlet jets for their rotation at a predetermined rate independent of the rate of flow of liquid through the nozzled outlet jets.
Abstract:
Cleaning a milk tank (1) includes rinsing the tank (1) with cold water and washing the tank (1) with a warm liquid. During rinsing, the tank (1) is finally rinsed with substantially warmer water than the cold water with which the tank (1) is initially rinsed, the cold water being cold enough to remove milk residues, such as proteins, from the milk tank (1). A dairy farm milk storage facility specifically adapted for carrying out this method is also described. Milk residues such as proteins are effectively rinsed away by the initially used cold water and no energy is consumed for heating this rinsing water. Subsequently the storage tank is gradually, evenly and very effectively pre-warmed by the final rinsing water prior to the washing stage, so less washing water is required to achieve the required washing temperature while thermal stresses occurring in the tank are kept low.
