The invention relates to a cleaning device as well as a method for cleaning wool,

In the recovery of wool it has been shown that a Most of the resulting wool is of little value because cleaning it is too difficult and therefore too expensive. In Australian Patent Specification Nos. <+03 108,403 and 403110 are devices and methods for Cleaning dirty wool described, but the perforated ones provided there tend to separate dirt Plates cause clogging because of the high fat content of the dirt contained in the wool.

In contrast, the object of the invention is to provide improved possibilities for cleaning dirty wool to create, in particular, to separate the dirt more easily and reliably from the wool, as well as the separated dirt particles easier and more reliable to remove.

The solution to this problem results from the features of the independent claims 1, 4 and 10.

Advantageous refinements and developments the WoIl re I η Igungsapparate according to claims 1 and 4 · result from the subclaims.

Drag with the WoI1reiηigungsapparat according to the invention the knocking fingers attached to a rotating drum the abandoned dirty wool circularly in a cleaning room, which is between the rotating drum and the rods attached to the outside of the drum are parallel to its axis of rotation. Happened in the process the wool the rods, which have both a burst and Have a cleaning effect on the wool. The brush effect is due to the whipping of the wool against the rods, while the cleaning effect is partially on this impact and partly on the existing centrifugal force is based. Furthermore, the rotating drum generates an air flow through the dirt separation spaces between the bars. Furthermore, the Rotate the rods freely, so that at least some of the separated dirt particles are also caused by the rotation of the rod is conveyed out of the cleaning room.

That of the drum's knocking fingers as it rotates generated air flow, in which the knocking finger has the effect of fan blades, the other owns

beneficial effect that the cleaned wool from the Cleaning apparatus is blown out. It will far more air is moved by the rotating drum than is necessary for the latter purpose Is. However, as already mentioned above, it is advantageous if the conveyed air flow through the dirt separation spaces pass between the rotatable rods, with large amounts of air being conveyed for this purpose are cheap.

In a preferred embodiment of the invention a receiving channel is attached to the downstream end of the cleaning apparatus, on which a partially curved duct is attached, which one for the exhaust air flow from the duct Represents flow resistance. As a result of this measure, a greater amount of air is conveyed between maintain the rotating rods, thus improving the cleaning efficiency.

The embodiment shown in the drawings of the WoI1reiηigungsapparates 10 according to the invention comprises a frame 11 which supports a housing. The housing consists of an upper part 12, a middle part 13 and a lower part 14, the latter one Has pair of side plates 15 extending above sloping downwardly sloping shaft walls are located. The shaft walls 16 are attached above a vibration conveyor 17, which is used to transport the separated WoI1 dirt to a discharge end 18 of the WoI1reiη Igungsapparates 10 is used.

The middle part 13 of the housing has side plates 21 on, between which a variety of rod support plates 22 is attached. Each rod support plate 22 has, with the exception of yours, semicircular extending upper edge 23 is a rectangular profile. Of the Curvature middle point of the semicircular curvature of the upper edge 23 lies on the axis of rotation of a beating drum

The top 12 of the housing has a top plate and side plates 26 which extend from the side plates 21 of the central part 13 extend upwards. the The base plate 28 of the upper part 12 is semi-circular

- 12 -

trained at the top. The surface of the bottom plate 28 is smooth. The center of curvature of the semi-cylindrical base plate 28 lies on the axis of rotation of the beating drum 2 ¹ +.

For clamping the upper part 12 with the middle part 13 a clamping device 30 is provided. To the Disassembly of the upper part 12 from the middle part 13 is furthermore, as can be seen from FIG. 5, a crane winch 31 is provided, by means of which the upper part 12 can be lifted off the beating drum 24. Another one Lifting gear 55 is used to lift the beating drum 24 from the sub1 14.

Each rod support plate 22 of the central part 13 is provided with a multiplicity of openings 34, which lie on a Te I1kreIsrad1 us slightly is greater than the radius of curvature of the upper edge 23 of the plate 22, so that between each opening and the Upper edge 23 is a narrow metal web. Each opening 34 serves to receive a rod 35, which at their ends through two openings 34-

- 13 -

is plugged. The plates 22 and their associated openings 34 are in the longitudinal direction of the drum 24 aligned, the of the plates 22 and their Openings 34 supported rods 35 a free Allow rotation of the rods 35.

The housing is also at its entry and exit points provided with end plates 37 and 38, on the outside of which pivot bearings 39 for the central shaft 41 of the Drum 24 are attached. The shaft 41 is with the Drum 24 over disc-shaped drum st inner plates 42 and connected to a rotary drive 40 located on the outside of the cleaning apparatus 10. The shaft 41 extends in the longitudinal direction through the housing of the cleaning apparatus 10. The tapping drum 24 has a cylinder wall 44, on which a plurality of L-shaped retaining rails for Knocking finger 45 is welded on. Any mounting rail 45 carries a plurality of radially outwardly projecting knocking fingers 44, which are arranged in a slightly spiral shape are so that the abandoned wool is conveyed through the cleaning room, which is between the beating drum 24 on the one hand and the rotating rods 35

- 14 -

as well as the smooth cylinder surface of the upper part 12 of the Housing is present.

At the discharge end of the housing is a tangential
Channel 48 provided to the passage of the conveyed by the drum 24 air together with that from the
Cleaning space conveyed out within the housing to enable cleaned wool. However, the discharge channel does not extend in a straight line in all cases, but in certain cases is connected to a curved channel 49, which runs first downwards and then upwards to provide a certain flow resistance for the air and wool flow and thus an increase in the air flow to achieve behind the rotatable rods 35.

How the Wollrein described above works The device is as follows.

The wool to be cleaned passes through a feed chute 51 CFIg. 2) Enter the cleaning room and is between the knocking fingers 46 and the rotating rods 35 and the cylindrical plate 28 out. The wool is there first of impact blocks at the end of the task the drum knocked. The wool is due to the

- 15 -

Centrifugal force against the upper and lower parts of the Thrown housing and then taken by the knocking fingers and gradually in the longitudinal direction the cleaning device transported, whereby the wool against both the smooth surface of the cylindrical plate 28 and against the rotating rods 35 is pressed. When pressing against the rotating rods 35, the friction of the wool bouncing against the rods causes a Rotation of all rods in the same direction. This rotational movement of the rods 35 is supported the separation of dirt particles from the wool the dirt penetration openings between neighboring Rods and the transport of these separated dirt particles outside the range of the rotating Poles. The finger bracket slides 45 call one Air flow out, which is part of the dirt particles entrains while another part of the dirt particles falls onto the conveyor belt 17 and is conveyed by this to a dirt elevator 52.

It is not always the case with the dirty ones around dry particles; rather, it is also

- 16 -

greasy particles, so these are inevitable knock down the rods 35. If one Dirt grease precipitation occurs, the rods 35 cleaned by hand with or without the application of heat. For this purpose, the middle part 13 of the housing of the Lower part 14 of the housing lifted up and lowered onto the carriage 53 pushed underneath, which be pulled away to one side. The drum 24 can still hang on the dismantled middle part 13, which, however, first during the normal cleaning process is lifted by means of a crane winch 55, as In Fig. 5 is shown.

In a further embodiment, the axis of rotation is the beating drum arranged vertically, with the entire wall surface surrounding the drum with parallel to the drum axis axis, rotatable Is provided with bars. This increases the cleaning effect and separates dirt even further improved.

Instead of the above-described curved channel 49 behind the discharge channel 48 for formation an air flow resistance can also be a straight one Channel used with a

- 17 -

Baffle plate or some other kind of damming device can be provided in order to impede the exit of the air flow from the cleaning apparatus.

It has been shown that the cleaning apparatus according to the invention is far more effective at cleaning Dirty wool than the cleaning apparatus according to the prior art mentioned at the beginning, which works with perforated plates.
