Description

The connection De pulls itself up on mobile ones arranged in an elevated position pneumatic cleaning devices for removing fiber waste, dust and the like in textile machine rooms, and more particularly, it relates to improved air blower impellers for mobile cleaning devices of the type that comprise a separate air system as a unitary unit, which make it possible to blow fiber waste down from textile machines and vacuuming aser waste from the floor on which the Textile machines are standing.

Various constructions have been in use for several years from mobile pneumatic cleaning devices used in iiextilfabriicen to fiber waste from textile machines and to remove these neighboring surfaces with the help of air blasts and to suck up fiber waste from the floor .. One of the most functional and least space consuming Constructions of this type is the combined, constructive uniform cleaning pre-

direction described in U.S. Patent 3,304,571. This cleaning device comprises suction and blower housings arranged one above the other, essentially nodding in flow connection, which are movably arranged on a rail above one or more rows of textile machines. The suction housing is provided with one or more hanging suction hoses or tubes, the lower ends or suction nozzles of which move in the immediate vicinity of the floor. The blowing case is provided with hanging Blasschläuchen, the w are equipped with air outlets, so that Blasluftströme on different parts can be directed to clean the -Textilmaschinen.

One of the most important new features of the mobile cleaning device according to the above-mentioned USA Jr'atenu is that the suction housing and the blower housing are arranged one above the other and are not in fluid communication with each other, so that it is possible, in the various G -to use 3-blade fan housings or impellers, which differ significantly in terms of their airflow properties. As mentioned in the above-mentioned U _a S. A. Patent, resulting in the purification by means of Blasluftströmen requirements that differ considerably from the requirements for cleaning by means of suction air. For example, the blown air should be kept clean, and it should be distributed in the form of several air flows of sufficient cross-section and with sufficient speed so that it is possible to clean different zones of "textile machines". The cleaning of floors however, requires the auxiliaries to maintain strong suction

In some of the difficulties that arise when fiber traps are to be filtered out of the building air and removed from the cleaning process, it has proven to be very expedient to guide the fiber incidents picked up by the suction nozzles through the impeller and remove the fiber waste the front of the suction fan and filter them out of the air. With such an arrangement, the rotor of the suction fan must be designed in such a way that "clogging of the rotor by the fiber waste passing through it is avoided. A suitable construction of such a suction fan rotor is described in the aforementioned IT.S.Ap patent." however, this patent Ü.SA two separate impellers are arranged according to a common axis and the like separated by a wall between the üauggebläsegehäuse and the Blasluftgehäuse. Although this arrangement has proved very successful in practice, but this is a danger that The present cover now provides a construction in which this difficulty is avoided and further parts of the gate are achieved.

An object of the invention is to provide a mobile cleaning device of the type mentioned, one above the other arranged, not in fl ow connection with one another

The inner ends of the blades of the second set on the side serving to generate blown air are spaced a substantial radial distance from the hub in order to minimize the turbulence that would otherwise occur near and around the hub Way to increase the airflow rate of the second set of blades. This different design and arrangement of the blades of the second set is possible because it is not necessary to design the blades so that they too

is supported and completed by a plate 17, which an electric motor 20 encloses and in a suitable manner on the Motor is mounted as in the referenced U.S.A. patent is described.

The motor 20 can be regarded as a component of a carriage which in a suitable manner carries the filter 16 and the housing 12 and 12 and is movable along the rail T which is arranged in an elevated position. Since the construction of the carriage and means for moving the carriage along the track T is fully described in said Patent ü.S.Ao-%, a more detailed explanation at this point is likely to be unnecessary.

The air inlet for the dauggehause 12 is formed by an air inlet chamber or a collecting container 21, the wall in a suitable ueise at the top of the top of the \ ie ttäuses 12 is mounted and communicates with the interior of the housing in connection ,, The inlet chamber 21 is provided with two hanging flexible construction hoses 22 which are connected to the chamber and extend into the passages on both sides of the row of machines H and carry open suction nozzles 23 near the bottom P.

“When air is sucked in through the nozzles 23, it is created Vacuum zones or suction air flows on the floor F, by means of their .Fiber waste and other light premdstocks from the neighboring ones i'läcnen of the floor are sucked off, so that aie via the suction hoses 22 and the air inlet chamber 21 to the Housing 12 arrive.

these associated chambers 25 for collecting the extracted Ma-, ■:; /> terials delivered. The collecting chambers 25 are provided with filter sieves 26 which hold back the fiber waste and the like, when the air is discharged from the chambers 25 through the screens 26 to the outside. The fiber waste is collected in the chambers 25 to be used in a suitable manner at a later point in time to be eliminated- ·. -

■ The air flows for both the blower housing 11 and for the suction housing 12 are produced with the aid of a single rotatable rotor or blower wheel 30. The fan or paddle wheel 30 comprises an annular partition or disc 31 which is disposed in a suitable opening of a plate 32, which latter the adjacent walls of the two housings 11 and 12 forms. The wall 31 thus forms a partition between the suction housing 12 and the blower housing 11 that are not are in flow connection with each other. On the partition wall 31 a hat 35 is formed with a substantially perpendicular shaft 36 of an electric motor 20 by a Wedge or the like. Is firmly connected. The hub 35 jumps opposite both sides of the partition wall 31 in front.

At the top of the partition wall 31 are several suction fan blades 37, which protrude into the suction chamber 12. According to FIG. 2, the blades 37 extend from the property 35 from substantially radially outward, but are against the Direction of rotation of the rotor 30 at a small angle tilted back. Since the blades 37 not only air upwards through the hoses 22, the inlet chamber 21, the housing 12 ·
