Definitions
- Both the primary and secondary air streams are discharged into the room approximately horizontally, with the secondar air stream being discharged at a level above the primary air stream.
- the secondary air stream further functions as a means to protect the ceiling of the room against spray and mist contained in the primary air stream.
- the instant invention generally relates to atomizers and particularly concerns an atomizer for liquids, such atomizer being of the type wherein a separate primary and secondary air stream is generated.
- Atomizers for liquids of the general type in which both a primary and a secondary air stream is produced and guided through the apparatus completely separate from one another are known to the art.
- This construction affords the advantage that dust particles which may have been suctioned into the atomizer apparatus with the non-filtered secondary air, remain relatively dry and do not tend to exhibit crust formations. In this manner, the operational readiness of the apparatus is maintained even if cleaning of the apparatus is only occasionally performed, which cleaning, however can be easily effected.
- the primary air stream as well as the secondary air stream emerge upwardly from the apparatus into the room.
- the secondary air stream which is primarily provided to assist the transportation and mixing of the primary air stream in which the mist is contained, must be guided and channeled through the atomizer apparatus so as to be properly accelerated. Additionally, discharge of the air stream in an upward direction necessitates that the apparatus be placed a sufficient distance from the ceiling of the room in which it is disposed so as to prevent spraying the ceiling with mist. Placing the apparatus in such a manner oftentimes is disadvantageous and limits its environment of use.
- the novel atomizer for liquids which incorporates this concept comprises a housing in which a water tank, a rotating atomizer means disposed above the water tank, two blowers, and inlet and outlet openings for both the primary and secondary air flows are provided.
- the novel apparatus is further characterized by the features that the air inlet opening for the secondary air stream is disposed on the top side of the housing and contains an air filter, the blower for the secondary air stream being defined by a radial blower.
- the outlet opening for the primary air stream is disposed beneath the outlet opening for the secondary air stream in the side of the atomizer housing.
- the secondary air blower comprises a radial blower and wherein the air inlet for the secondary air stream is disposed on the top side of the housing, a very simple and quiet guidance of the air is obtained, this simple and quiet guidance itself constituting a major advantage over prior-art constructions. Filtering of the secondary air stream in the manner contemplated by the instant invention not only protects the atomizer apparatus against dirt, but further prevents dirt from accumulating on the ceiling under which flows the secondary air stream, this stream gradually mixing with the primary air stream contained in the most.
- FIG. 1 depicts a sectional elevational view of the novel atomizer for liquids constructed in accordance with the instant invention.
- FIG. 2 depicts the novel atomizer for liquids in a side elevational view, with portions thereof broken away for illustrative clarity.
- reference numeral 2 serves to identify the lower portion of a housing which is constructed to have an approximately square configuration.
- the bottom 8 of the housing portion slants downwardly relative to the horizontal and runs from a forward wall 4 towards a rearward wall 6.
- Bottom 8 is provided with a square recess 10 into which a primary air filter 14 is inserted and held by frame 12.
- a cover plate 16 also disposed in frame 12 is provided with perforated partitions or holes 18 (FIG. 2) which form inlet openings for the primary air flow.
- the lower portion 2 of the housing contains, in its interior, a liquid storage tank 20 which is coupled to a nonillustrated feed line for transporting the liquid to the atomizer.
- a float unit or device 22 as depicted in FIG. 2 is secured to the rear wall of the housing portion and cooperates with the liquid tank 20, the float unit serving to control the intake of liquids into the tank in known manner.
- the uppermost area 24 of the lower housing portion 2 is provided with a circular opening 26 in which an atomizer unit of known construction is inserted, such unit generally being designated by reference numeral 30.
- the atomizer unit will be seen to comprise a ring jacket 32 supported on the lower portion 2 of the housing, a suction extension member 34, a suction pump 36, a blower disc 40 provided with blades 38, a centrifugal disc 42, a guide disc 44, and a stationary atomizer ring 46.
- the atomizer ring 46 is supported on a motor support plate 48 which, together with a housing member 50, surrounds an electric motor 52.
- Electric motor 52 is vertically disposed and, on its downwardly extending shaft end 54, carries discs 40, 42 and 44 and further operates suction pump 36.
- a radial blower 58 is disposed, such blower being located above the housing member 50.
- Housing member 50 which supports the motor 52 and the atomizer ring 46 is itself supported by means of an annular flange or sealing ring 60 which surrounds the upper end of the ring jacket. Housing member 50 is therein rotatable about a vertical axis relative to the lower portion 2 of the housing.
- a cover member 62 is disposed upon the housing member 50 and has a configuration corresponding to the rectangular configuration of housing member 50.
- a rectangular-shaped opening 64 is provided in the upper portion of the cover member 62 and contains a filter plate 66 supported on ribs 68 of an inlet member 70.
- Inlet member 70 defines a ring-shaped opening 72 coaxially disposed to the radial blower 58 immediately above the same.
- a separating wall 74 is provided and serves to separate the secondary air chamber 76 from the primary air chamber 78, which primary air chamber is, in turn, connected to a mixing chamber 82 between atomizer ring 46 and ring jacket 32 via a ring-shaped opening 80 in the underside of the housing member 50.
- the front side 84 of the upper portion of the housing formed by members 50 and 62 defines ribbed grid-containing outlet openings 86 and 88 connected to the secondary and primary air chambers 76 and 78, respectively, via blow-out chutes 90 and 92.
- Blow-out chutes 90 and 92 are provided with vertical guide blades 94 with chute 90 being additionally provided with a horizontal guide member 96.
- liquids to be atomized such as water, for example, is suctioned-in from the liquid storage tank 20 by suction pump 36 and is conveyed to discs 40 and 42 which serve to throw the water against the atomizer ring.
- primary air is suctioned-in at the atomizer disc by blades 38 which form the primary air blower, this primary air entering through opening 18 and being purified and filtered as same passes through primary air filter 14.
- the primary air flows about the water tank 20 and is suctioned into ring jacket 32 whereupon such air is conveyed beneath the discs 40 and 42 into the mixing chamber 82 after passing through the atomizer ring.
- the purified primary air now mixes with the mist or vapor formed by the atomizer ring 46, such mixing taking place in the mixing chamber 82, and the primary air then passes through opening 80 into primary air chamber 78 in the upper portions 50 and 62 of the housing.
- the air is deflected in primary air chamber 78 towards the blowout chute 92 with the air flow being directed through the guide blades 94. Thereupon, the primary air emerges from the liquid atomizer through outlet opening 88.
- the secondary air is taken or suctioned into the atomizer through opening 64 and filter plate 66, respectively, disposed in the cover member 62, the suction action being effected by the radial blower 58 which, together with the primary air blower 38, the pump 36 and the rotatable atomizer discs, is driven by the electric motor 52.
- the purified or filtered secondary air now fiows between the filter plate 66 and the inlet member 70 toward opening 72 and is then transported into the secondary air chamber 4t 76 by the radial blower 58.
- the secondary air stream leaves the atomizer via the blow-out chute and outlet opening '86 during the course of which such secondary air is likewise directed through guide members 94 and 96.
- the discharge air streams can be directed into the room in any desired direction throughout an enclosed angle of approximately 90 relative to the rear wall 6 of the atomizer, which wall would be secured to a respective room wall.
- cover member 62 can be removed from the atomizer simply by lifting the same from housing member 50.
- the upper portions 50 and 62 of the housing together with the atomizer unit 30 can be lifted out of the housing lower portion 2 thereby significantly simplifying cleaning and maintenance operations of the atomizer.
