Description
- The present invention relates to a frameless containment system with magnetic locking means.
- When performing maintenance work, such as abrasive blasting operations, it is often desirable to be able to reduce dissemination of particles, such as debris, dust or blasting media. To protect surrounding equipment, installations and nearby personnel, it is thus often necessary to build a containment system or enclosure around an area that needs to be maintained.
- Enclosures of this type are often constructed from a large rigid frame covered by a membrane material.
- As an alternative to the use of rigid frames, flexible enclosure have shown better versatility.
- For example,
WO 2016/198419 discloses a frameless containement system for providing a substantially dust-tight working space surrounding a work area. However, ensuring substantially dust-tight connection along the edges of the working area protected by the enclosure have shown to be not straight forward. Abrasive blasting operations and other operations involving flying particles may also pose a serious liability to the operator performing the operation. Thus, tightness of the enclosure around the edges of the working area is rather crucial to avoid undesired distribution of particles in the vicinity of the working area. Unfortunately, the joining of the edges of these enclosures around the edges of the working area is very often not sufficient requiring more permanent additional sealing means to provide substantially dust-tight connection. However, more permanent additional sealing means reduce the versatility and the removal of the enclosure when blasting operations are terminated. - Furthermore, permanent additional sealing means, such as glue, has also the disadvantage that they may contaminate the working area leading eventually to a less efficient treatment of the working area.
- Hence, there is a need for a system ensuring dust-tight connection between the enclosure and the edges of the working area defined by the enclosure.
- Hence, an improved containment system would be advantageous, and in particular a containment system that ensure dust-tight connection between the edges of the working area and the areas surrounding the enclosure.
- An object of the present invention is to provide a dust tight containment system ensuring dust-tight connection between the edge of the containment system and the edge of the working area.
- In particular, it may be seen as an object of the present invention to provide a frameless containment system that solves the above-mentioned problems of the prior art with a removable sealing mean.
- An object of the present invention may be seen as to provide an alternative to the prior art.
- Thus, the above described object and several other objects are intended to be obtained in a first aspect of the invention by providing a frameless containment system according to claim for providing a substantially dust-tight working space surrounding a work area, such as a work area on a ferritic or magnetic surface, the frameless containment system comprising: a flexible enclosure comprising one or more flexible sheets adapted to be placed around the work area, the one or more flexible sheets comprising an outlet for releasing gas and particles and tides, one or more gas inlet devices; wherein the flexible enclosure, when placed around the work area, defines a dust-tight working space through magnetic means, located, at least partially, within the edge of the flexible enclosure. When assembled, said flexible enclosure comprises one or more wedge shaped elements between said magnetic means and said working area, wherein said one or more wedge shaped elements comprise said outlet for releasing gas and particles and said one or more gas inlet devices.
- The flexible enclosure is adapted to be placed, positioned or assembled around the work area.
- The outlet for releasing gas and particles may release gas vapors and material originated from the actions, such as surface treatments, performed underneath the flexible enclosure.
- The outlet for releasing gas and particles may be connected to a suction hose so as to allow removal of gas and particles by suction.
- The flexible enclosure may be composed by one or more flexible sheets having a plurality of edges adapted to be assembled providing a main body section. The plurality of edges of the flexible sheets may be adapted for being assembled around structures extending in and out of the working space. The magnetic means may be located, at least partially, within the edge of the flexible enclosure defined by the boundaries or plurality of edges of the one or more flexible sheets.
- In some embodiments, the one or more flexible sheets are made from a transparent polymer-based material. It is thus possible to see through the flexible enclosure during operation of the blasting nozzle or the like positioned inside the enclosure. More specifically the material may be a polyethylene composition comprising flame-retardants and/or antistatic agents. Antistatic or electrically dissipative properties may prevent dust from attaching to the inside of the flexible enclosure, hence, preserving visibility.
- In some further embodiments, the one or more flexible sheets are made of different materials.
- In some embodiments, the one or more gas inlet devices are adapted to introduce compressed fluids, such as gas or liquids, into the flexible enclosure, thereby keeping the frameless containment erected. The containment is thus kept erected without the need of a frame.
- In some further embodiments, the one or more gas inlet devices are adapted to introduce compressed fluids, such as gas or liquids, and particles, thereby allowing for introduction of materials suitable for surface treatment within the work area.
- The one or more gas inlet devices may thus be used for both keeping the frameless containment system erected and for introducing materials to perform surface treatment.
- In some embodiments, the one or more gas inlet devices comprise a second gas inlet device which is adapted to keep the frameless containment system erected.
- In some embodiments, the work area is a surface to be subjected to a surface treatment such as abrasive blasting or painting.
- In some further embodiments, the outlet for releasing gas and particles is configured for connecting a vacuum device for drawing gas and particles out of the flexible enclosure.
- Thus, the outlet may be configured for connecting to a suction hose.
- In some embodiments, the frameless containment system further comprising a vacuum device connected to the outlet for releasing gas and particles, the vacuum device suitable for drawing gas and particles out of the flexible enclosure.
- In some further embodiments, the magnetic means comprise permanent magnets arranged in a chain structure.
- For example, the permanent magnets may be block-shaped permanent magnets arranged in a chain structure.
- In some embodiments, the magnetic means comprises electromagnets.
- The chain structure may comprise nonmagnetic materials.
- In some embodiments, the magnetic means are attached to the edge of the flexible enclosure.
- The magnetic means maybe within the edge of the flexible enclosure or attached to or within the plurality of edges of the flexible sheets.
- In some embodiments, the magnetic means are located within sleeves at the edge of the flexible enclosure.
- The sleeves may comprise metallic materials, such as metallic braids.
- The sleeves may also comprise plastic, rubber or other materials.
- In some embodiments, the magnetic means has a magnetic strength between 0.3 N/mm to 30 N/mm, such as between 1 N/mm and 5 N/mm.
- The force measured when pulling the magnets from the surface, depends on the strength of the magnet and the distance from the magnet to the ferritic surface or to another magnet. The strength of the magnet depends on the quality of material and the size and shape of the magnet. The distance is defined by the thickness of the braid, such as a metallic braid, the sheeting thickness and the thickness of the surface treatment, such as the paint, or other surface substances, such as the one produced by corrosion. The resultant pull force is defined in N/mm, wherein the length measurement relates to the length of the magnetic means, such as a magnetic chain.
- In practical use, the wanted pull force is typically between 0.3 N/mm to 2 N/mm. As distance between the magnets and the ferritic surface or another magnet, can typically differ from 0.1 mm to 15 mm depending on the thickness of the paint, braid and sheeting, the magnet force of the magnets measured when pulling the magnets from a plane steel surface, 5 mm thick, can differ between 0.3 N/mm to 30 N/mm, when measured on a row of magnets from 50 to 100 mm long.
- Magnets come in different temperature classes, and for work on hot surfaces a suitable temperature class should be chosen.
- The magnets are assembled with alternated polarity.
- The magnetic means has a magnetic strength between 1 N/mm and 5 N/mm when measured on a 5 mm thick steel plate with a roughness of 0-100 µm, wherein the length measurement relates to the length of the magnetic means, such as a magnetic chain.
- The specific magnetic strength between 0.3 N/mm to 30 N/mm, such as between 1 N/mm and 5 N/mm, is necessary so as to allow for keeping the flexible enclosure attached to the work area during operation and at the same time allowing for removal after use.
- In that, it is an optimized range in relation to the needs of the flexible enclosure, i.e. tight during operation but removable upon pulling action from the user. Thus, the magnetic means may comprise a row of permanent block shaped magnets placed inside a metallic braided sleeve. The ends of the sleeves may be closed with tape. The magnetic means are thus flexible and can be bent and can be attached and removed easily. This in turn allows for efficient fastening of the frameless containment system to magnetic/ferrous structures with complex structures.
- In some further embodiments, the frameless containment system further comprises an inlet opening, such as a blasting hole, suitable for introducing compressed gas and particles.
- The particles may be blasting media or paint, thus blasting may be achieved through a separate line via the inlet opening.
- The one or more wedge shaped elements may comprise magnetic materials. The one or more wedge may thus be part of the magnetic locking system and provide a robust structure for the location of the outlet for releasing gas and particles and the one or more gas inlet devices.
- The edges of the one or more flexible sheets may be adapted to be joined onsite during assembly of the flexible enclosure around the work area. Additionally, some of the edges, such as the edges of the parts of the flexible sheets defining the lower funnel-shaped section, may be pre-joined prior to delivery of the flexible enclosure.
- The edges may also be adapted for being assembled around structures extending in and out of the working space, for example via magnetic means, such as one or more magnets or components comprising magnetic materials, located within the edges, to provide a substantially dust-tight connection.
- In some embodiments, magnetic means may comprise additional magnetic means, such as one or more magnets located, at least partially, along the edges of the openings of the flexible enclosure so as to provide substantially dust-tight connection between the pipe and the flexible sheets.
- The first, and other aspects of the present invention may each be combined with any of the other aspects and embodiments. These and other aspects and embodiments of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
- The frameless containment system according to the invention will now be described in more detail with regard to the accompanying figures.
