Definitions

the invention relates to a device for applying a coating medium to at least a partial surface of an elongated work piece in a vacuum chamber, consisting of a housing with a storage container having an inclined bottom and an air line opening into the same, and a separating device located above the storage container.
a coating medium on at least part of their surface.
the workpieces often consist of wood or materials containing wood.
Pumpable and filterable, nozzle-compatible liquids such as pigment solutions, paints, varnishes, primers and impregnants are used as coating media.
This coating medium is located in a storage container, which is usually formed in the lower region of a housing and has an inclined bottom.
the coating medium is conveyed from this storage container to an application unit which is designed as a spray or flood frame or as a slot nozzle - depending on the profile or independent of the profile.
This application unit is formed in a so-called vacuum chamber, which is connected to a vacuum tank.
the workpiece to be coated is now sent through this stream of finely atomized coating medium and air.
so-called pore air is extracted from the workpiece and, on the other hand, the coating medium accumulates intensively on the intended surfaces of the workpiece.
Excess coating medium is drawn off together with the air from the vacuum chamber and returned to the housing with the storage container.
the air flow loaded with excess coating medium enters an opening in the housing located above the storage container and meets an impact plate likewise inserted above the storage container.
the air flow is first deflected downwards before it is sucked up into the vacuum tank via a perforated plate or the like.
the baffle plate and the perforated plate together are also referred to as a separator.
the coating medium is pumped again to the application unit in the vacuum chamber.
the coating medium contains oil or oil-containing components
This oil mist can affect the further coating process. If the air extracted from the vacuum chamber is not returned to the vacuum tank, but instead is directed into the work area, the quality of the room air is significantly impaired.
the invention is therefore based on the object of designing a device for applying a coating medium to at least one partial surface of an elongated workpiece in such a way that the air stream flowing out of the vacuum chamber is treated before it re-enters the vacuum tank or in the work space in such a way that the air stream unites Has a degree of purity that complies with the legal requirements, so that on the one hand the coating process is not impaired and on the other hand the exhaust air can also be introduced into the work area if necessary.
housing 1 of a device for applying a coating medium to at least one partial surface of an elongated workpiece which is transported in its longitudinal direction and which has in its lower region a storage container 2 with an inclined bottom 3 for receiving the coating medium.
the housing 1 Above the storage container 2, the housing 1 has an opening 4, through which air can flow into the lower region of the housing 1.
This air comes from a vacuum chamber in which a coating medium is applied to elongated workpieces on at least part of the surface.
the air sucked out of the vacuum chamber and flowing into the housing 1 via the opening 4 thus contains finely atomized coating medium and possibly also dust. This dust can get into the air flow in that air is also sucked in due to the vacuum in the vacuum chamber.
baffle plate 5 in the housing 1, which is directed downwards in the direction of the storage container 2 and deflects the inflowing air downwards.
an inclined intermediate plate 6 is provided, into which a perforated plate 7, for example made of stainless steel, is inserted.
a first intermediate floor 8 in which an interchangeable and, for example, regenerable air filter 9 is used.
a second intermediate floor 10 which is provided with a plurality of openings 11. Each opening 11 is enclosed by a short, tubular connecting piece 12, which in turn serves to receive a sleeve-like filter rod 13.
Each filter rod 13 is advantageously formed in two layers and consists of an inner, fine-meshed collecting layer and an outer, coarse-meshed drainage layer made of borosilicate glass fibers.
the sleeve-like filter rods 13 are formed closed at their end facing away from the second intermediate floor 10, that is to say at the top.
the housing 1 ends above the filter rods 13 and merges into an opening 14 to which, for example, a vacuum line can be connected.
the air stream entering the lower region of the housing 1 via the opening 4 is now first deflected downward by the baffle plate 5 before it flows upwards again through the perforated plate 7. This on the one hand deflects the air flow while on the other hand the air expands, which inevitably leads to a reduction in the flow velocity of the air.
existing particles of the coating medium in the air that has entered are separated out and returned to the storage container 2.
the air flows through the dust filter 9. Any dust particles contained in the air are filtered out.
the air filter 9 is either replaced as a replaceable filter and can be replaced. However, it is also possible to use a filter that can be regenerated and thus used multiple times.
the air flowing upwards through the dust filter 9 of the intermediate base 8 now reaches the openings 11 of the second intermediate base 10 and then flows through the sleeve-like filter rods 13 made of borosilicate glass fibers.
the inner layer of the sleeve-like filter rods acts as a so-called fine-meshed collecting layer for an oil mist that may be present in the air, for example consisting of aerosol particles.
aerosol particles coalesce into larger droplets on the fine glass fiber threads of the inner layer and are discharged to the outside through the outer, coarse-mesh drainage layer.
these droplets combine to form larger drops of liquid, which then flow downward under the force of gravity and are collected by the intermediate floor 10, which acts as a collecting device.
the oily liquid collecting on the intermediate floor 10 can be collected in a container 18, for example via a line 15 with valves 16, 17.
the liquid collected here can, depending on requirements, be processed or returned directly to the storage container 2.
a rotary valve can also be used here.
