- ABSTRACT Philpitt [5 7 ABSTRACT A washing machine comprising an elongated rotating tube having several, separate treatment sections and means positioned behind one or more treatment sections for restricting the flow area of the tube so as to obtain a more uniform distribution of the washing goods in the preceding sections.
- the present invention relates to a washing machine of the type comprising an elongated rotating tube, which is divided into a plurality of successive sections and through which the washing goods is passed and treated, e.g. by means of washing, bleaching, rinsing in the various sections.
- Washing machines comprising an elongated, rotating tube with a plurality of treatment sections are previously known.
- the tube of such machines are normally arranged slightly inclined relative the horizontal plane and the washing goods is fed into the higher located end of the tube and is then with the assistance of the inclination and rotation of the tube caused to pass through the various treatment sections of the tube to the other end of the tube where it is discharged.
- a treatment liquid is added, e.g. washing liquid to the washing goods in the tube.
- This washing liquid is usually added to the washing goods by the tube throughout its length or portions thereof being immersed with the lowermost portion of its circumference into one or more liquid containers and the mantle surface of the tube being perforated so that during the rotation of the tube the washing liquid is allowed to pass from the liquid container into the tube to the washing goods and back again.
- the operations are usually divided into a prewashing, whereafter one or more main washings follow, bleaching, one or more rinsings, and an anti-static treatment.
- the prewashing is normally performed at a different temperature from the main washing and with other additions of washing materials.
- bleaching and anti-static treatment the addition of further chemicals is required and at the rinsing pure water must be added. Therefore, in order to attain a perfect result an accurate control of the operations and processes in the various treatment sections is required.
- This control comprises an accurate supervision of temperatures and chemical additions and it is therefore necessary to delimit the various sections from each other as effectively as possible, so that the temperature and the chemicals in the treatment liquid utilized in one section do not to any substantial extent influence the temperature and the composition of the treatment liquid utilized in a preceding or succeeding section.
- tubular washing machines of the type mentioned above it has proved difficult in tubular washing machines of the type mentioned above to attain a satisfactory control of the treatment processes in all the various sections, since the sections have influenced each other and the washing liquid has flowed in an uncontrollable manner from one section into another, and the quantity of washing goods is different in different sections.
- the main object of the present invention is to provide a washing machine of the type mentioned above, wherein the various treatment operations can be controlled and supervised in a substantially more efficient manner than has previously been possible so as to obtain a better washing result and a higher capacity of the machine.
- the varying quantity of washing goods in the various sections as mentioned above occurs since the washing goods fed into the inlet end of the tube meets a certain resistance from the washing goods already present in the tube, whereby the flow rate of the washing goods is reduced and the quantity of washing goods is increased in the first sections. At the end of the tube this resistance to the washing goods is no more present and the flow will be more rapid there at the same time as the quantity of washing goods will be smaller.
- the quantity of washing goods at least in some sections is substantially constant. The whole washing tube with all the sections is maintained in rotation at a certain speed and is reversed at certain intervals.
- the rotary speed and the revising intervals must be selected so that they fit all the sections, which may require considerablecompromises, if the quantities of washing goods are very different in the tube. With a more even quantity of washing goods in the various sections of the tube the washing machine can be dimensioned and the washing process can be controlled to optimum, which causes a better washing result and a higher capacity of the machine.
- a more even quantity of washing goods in the tube is obtained according to the invention by placing at a convenient position in the tube a member, e.g. a baffle provided with a central aperture, which limits the flow area of the tube, whereby the quantity of washing goods in the sections in front of the baffle increases and becomesmore even at the same time as the quantity of washing goods in the sections after the baffle becomes substantially smaller, which is an advantage during e.g. rinsing.
- a member e.g. a baffle provided with a central aperture
- washing liquid is added to the goods by means of buckets, which are provided on the rotating tube at the external periphery thereof and which during the rotation of the tube pass through a washing liquid container below the tube and thereby carry washing liquid, which is then during the rotation of the tube introduced through apertures in the washing tube and poured over the washing goods in order to perform the washing operation required.
- the washing tube is further provided with perforations for the washing liquid so that it can flow back into the same washing liquid container.
- Washing machines of the type described have the great advantage that there is no liquid level in the tube since the capacity of the buckets, the size of the draining holes and the rotary speed can be matched in such a manner that the liquid quantity provided by the buckets is drained through the draining holes at such a speed that no significant liquid level is ever formed in the tube.
- This fact brings the advantage that the clothes to be washed do not fall down into a liquid surface, as is usual in other types of washing machines, but against the wall of the tube or other clothes in the tube, which provides a better washing result.
- the height of fall of the clothes to be washed in the tube can also be controlled to a certain extent by the rotary speed of the tube. Higher rotary speeds give a larger height of fall up to a certain limit.
- FIG. 1 illustrates a side view, partly in section, of a tubular washing machine according to the invention
- FIG. 2 at an enlarged scale a section through the washing machine
- FIG. 3 a cross-section normally of the tube through a portion of a tube and a bucket
- FIG. 4 a suitable array of perforations for a rib introducing the treatment liquid.
- the washing machine as illustrated in FIG. 1 comprises an elongated tube with an inlet aperture 10a and an outlet aperture 10b for the washing goods to be treated. Below the tube there is a plurality of troughs or containers l1, l2, 13 for treatment liquid.
- the tube is provided with a plurality of buckets 14 along its external periphery, which are adapted to pass through the liquid containers below the tube during the rotation of the tube and thereby carry treatment liquid, which is then poured out of the bucket and projected into the tube, when the buckets have arrived at a higher position during the rotation of the tube.
- the tube is divided into' a plurality of treatment sections 15, 16, 17 and each section has its separate container 11, 12, 13 for treatment liquid.
- Each section comprises one or two rings of buckets, depending on the length-of the section. Of course more rings of buckets can be used than has been illustrated, if this is necessary for the operation.
- the washing tube is shown in FIG. 1 with certain parts removed in an area immediately in front of the last but one rings of buckets. In this area there is illustrated a baffle 18, which is provided with a central aperture 19. Conveniently the central aperture 19 has a diameter, which is 40-60 percent of the diameter of the baffle, depending on the washing goods.
- This baffle is adapted to restrict the flow area in the tube so that a more even quantity of washing goods is obtained in the sections located in front of the baffle, i.e. between the inlet aperture 10a and the baffle 18.
- the sections located rearwardly of the baffle are substantially intended for the rinsing of the washing goods.
- the ready washing goods are fed out onto a conveyor, not illustrated, or to any other transport device.
- the various liquid containers ll, 12, 13 below the tube are, in a manner not illustrated, interconnected by means of piping and valve members so as to allow the supply of suitable quantities of various substances and liquids and on the other hand the transfer of various liquid quantities from or to the other sections if desired. (e.g., it might be convenient to utilize used rinsing water in a section for prewashing.)
- These valves can be moved easily depending on the quantity. and type of washing goods introduced into the washing machine.
- the washing tube is rotatably supported within and surrounded by a housing 20, which is supported at its rearward end pivotally in a vertical direction in a frame 21 and in addition at its forward end connected with a lift device 22, which allows a varying inclination of the tube 10 for adaption to various washing conditions.
- the washing tube 10 proper is rotatably supported within said housing and is supported by means of roller bearings 23 in two positions.
- the tube is further provided with members for the rotation of the tube at a variable speed and the reversal of the rotary direction. These members, however, have not been illustrated in detail, since they form no part of the present invention.
- Dot-dash lines 20a illustrate the machine with the inlet end of the washing tube lifted to its topmost position.
- the machine illustrated has an overall length of about 12 meters and the tube has a diameter of about 1,2 meters.
- the left end, as shown in FIG. 1, the inlet end can be lifted about 300 mm, which position is used for emptying the tube but the normal position of operation is mm higher than the outlet end. It is also possible to lower the inlet end so that it will be positioned lower than the outlet end. This lowering under the outlet end, however, can not attain more than about 80 mm.
- the rotary speed is conveniently maintained at 25-30 revolutions per minute.
- the machine has an approximate capacity of 1,500 kg dry washing goods per hour.
- FIG. 2 shows a section 17 of the machine at an enlarged scale.
- the'tube 10 comprises two parts, one tight part 24 and one perforated part 25, said perforated part serving as a drain for returning the treatment liquid to the container 13.
- the tube is provided with internal hollow ribs 26 which are adapted to increase the lift height of the washing goods within the tube.
- the ribs are provided with perforations 27 of the type illustrated more closely in FIG. 4.
- the buckets 14 are arranged at the external side of the tube 10 in connection with these perforated areas on the ribs so as to allow the inlet of the treatment liquid lifted by the buckets.
- the buckets 14 are located so that they partially overlap the portion 25 provided with drain apertures of the tube in the section.
- said overlapping is not necessary but it is possible to dimension the section so that in one section a certain spacing is provided between the rearward edge of the buckets and the forward edge of the perforation of the tube.
- baffle edge 28 which extends substantially radially from the internal wall of the tube 10 and serves to prevent treatment liquid from flowing into the succeeding section.
- the baffle edge should not be so high that the passage of washing goods is prevented.
- an external baffle edge 28a Externally of the rotating tube there is an external baffle edge 28a, which is bent forwardly towards the inlet aperture of the tube and prevents treatment liquid from flowing into the succeeding section via the external side of the tube.
- FIG. 3 shows a cross section at an enlarged scale through a bucket 14 of the type utilized on the rotating washing tube 10 and the arrangement of the bucket in connection with an axial rib 26 arranged in the interior of the tube 10.
- the bucket 14 comprises a base plate 14a, which is provided at either end with an edge 14b bent upwardly so as to hold treatmentliquid, which has been collected from the container into which the bucket has been immersed during the rotation of the tube.
- the bucket is also provided with side edges, not
- the base plate of the bucket is connected with a wall 29 projecting normally from the base plate and extending in a direction towards the centre axis in the rib 26.
- Said wall 29 is adapted to guide the treatment liquid into the rib 26, when the bucket has arrived at a lifted position due to the rotation of the tube.
- the bucket is formed symmetrically relative the wall 29 so that it will operate independently of the rotary direction of the tube.
- the bucket 14 is mounted on a flange 30 bent outwardly on the periphery of the tube.
- the rib 26, which is located in the interior of the tube, is also secured to said flange 30.
- the centre wall 29 of the bucket is terminated at a certain distance from the crest 26a of the rib, as clearly illustrated in FIG. 3.
- the interspace between the centre wall and the rib provides a better distribution of the treatment liquid fed into the tube.
- an angle bar 31 at either side of the central wall 29 of the bucket.
- Said angle bars 31 have a leg extending inwardly in the direction of the centre wall 29 so that a baffle edge is formed for preventing return flow of liquid from the rib into the bucket.
- the baffle edge is arranged approximately along the periphery of the tube and consequently externally of the perforation of the rib 26, as seen from the centre of tube.
- the array of perforations for the rib 26 as illustrated in H0. 4 presents a number of equally sized holes, which are arranged in rows, saidrows being mutually staggered in a longitudinal direction by a spacing corresponding to half the distance between two holes.
- the diameter of the holes is about 10 mm
- the spacing between the rows is about 16 mm
- the spacing between the holes in the same row is about 18 mm.
- the dimensions indicated and the arrangement illustrated is, of course, only intended as examples. A very large number of different arrays of holes or perforations can, of course, be used with substantially the same function.
- the sections can be made of different length, size and shape, whereby a certain treatment process is repeated a plurality of times in each section. It is, of course, also possible to provide means in order to restrict the flow area of the tube at a plurality of different locations in the tube so that consequently a plurality of series of sections with succeeding restricting means are obtained, if it is desirable to have a plurality of series of sections with substantially constant but mutually different quantity of washinggoods or level of washing goods.
- the restriction of the flow area of the tube can also be performed in other Ways than by utilization of a baffle with a central aperture, e.g. by means of a tapering shape of the washing tube.
- the number of buckets around the periphery of the tube and the arrangement of the inlet apertures for the treatmentliquid and draining apertures for the treatment liquid from the tube can also be formed in many different ways. It is possible that the buckets can be replaced by a fixed piping system arranged at the upper part of the rotary path of the tube, said piping system injecting treatment liquid into the rotating tube.
- the external baffle edge can also have many different shapes, e.g. consist of an edge abutting the tube for the removal of liquid or be replaced by an air flow.
