Patented July 15, 1930 UNITED STATES PATENT OFFICE AUGUST AELDERT, F DUSSELDORF, GERMANY MACHINE FOR CLEANING PAPER BAGS AND THE LIKE Application filed October 5, 1927, Serial No. 224,194, and in Germany September 6, 1926.
The invention relates to a machine for cleaning paper rags or the like.
Machines for cleaning paper are already known, which are Eharacterized in that the dust is sucked outwardly through a station ary sieve surrounding the device. But a complete removal of the dust is not possible in this manner. The present invention gives a machine in which complete cleaning is given and also eflicient removal of the dust, breaking and tearing devices on a rapidly rotating drum being employed with powerful suction in the interior of the drum so that the ma terial to be cleaned until its final discharge from the cleaning apparatus is agitated within the container and the dusty matter drawn from it is sucked inwardly and released by means of sieve-like apertures in the upper surface of the drum and the edge of the rear wall which extends above the drum.
The object of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a side view and Fig. 2 is a plan view of the machine. The drum a of conical form is arranged in a casing b and mounted upon a rotary spindle c. The drum as well as the casing may be provided in a known manner with teeth, claws, knives or the like all. A hopper A for the introduction into the machine of the material to be cleaned and freed from dust is mounted at the narrowed end of the drum. The cover part of the casing can be formed with corru ations or perforations or may be grid-shapetl according to the purpose in View. The casing of the drum is provided with sieve-like apertures. A fan V serves for drawing off the dust.
The material to be cleaned is thrown into the hopper A of the machine is seized by the tearing devices (Z and through the centrifugal force of the rapidly rotating drum a and the conical formation of the drum is driven through the space between the drum and the casing and thoroughly agitated, until the material arrives at the other end of the drum and is here discharged through the exit apertures B in a cleaned state. The suction of the dust produced by the cleaning which is collected in the space between the drum and the casing is efi'ected through the famwhich draws the dust inwardly through the holes in the outer surface of the drum into the interior of the latter and then out of the latter.
In order to produce a uniform suction through the whole space the suction device may be located directly in the interior of the drum, or the suction maybe strengthened at any desired point.
The complete abstraction of the dust cloud may be more effectually ensured in that the rear wall of the drum on the side of the fan V can be extended over the outer surface of the drum and so far until it contacts with the inner wall of the casing Z) and is connected with this by means of suitable leads. The edge of the rear wall extending over the drum is provided with sieve-like apertures. The fan V is then arranged in such a manner that the suction of the dust mixture is etfected as much through the holes in the outer surfaces of the drum as through the holes in the forward edge of the rear wall. I The protruding edge of the rear wall of the drum can be provided either corrugated or smooth. The material is fed into the hopper A and falls into the space between the hopper and the casing. The rotating drum with its attached knives tears and fibers the material and separates from it the dirt and dust. This is drawn off through the perforated sides of the drum or the section of the casing that is perforated, the material due to the conical shape of the drum being fed from the receiving end to the delivery hopper B.
I claim A. machine for cleaning and fibering waste 7 material comprisng a housing, a casing mounted in the housing, the upper portion of the casing being solid and the lower portion of the casing being perforated, a perforated conical shaped drum rotatably mounted in the casing, teeth on the outside of the drum. a hopper admitting material between the drum and the casing at the reduced end of the drum. and a fan mounted at one end of the housing wholly beyond the drum to create a suction on the inside of the drum and the outside of the casing.
