Abstract

The inner drum (1) comprises two separate half-shells (2,3) each extending across half of the drum periphery. At least one half-shell (3) can be shifted in the axial direction (26) in relation to the other half-shell (3). The inner space of each shell (2,3) is divided by at least one partition (21-24) into at least two adjacent parts (12-17). When the inner drum rotates, at least one section of a half-shell (2) forms a joint inner drum chamber (18-20) with at least one opposite section of the other shell (3).

Description

The invention relates to a drying device for laundry with a housing Semantle for the air flow for moisture removal and with one in it rotating drum and perforated to allow air to pass through as a cam always for laundry.

Known such drying devices are single drum machines with sta tional outer drum and one in a substantially horizontal Drum axis rotating driven inner drum. The inner drum is there usually from a hollow cylindrical or tubular jacket made of perforated Stainless steel sheet passing through the inner drum at its inner axial end rear wall forming, essentially aligned radially to the drum axis Stainless steel sheet is closed. The front wall delimiting the other end differs from the back wall in that it has a central filler opening Has for the item of laundry to be dried, which only after filling is closed by a door hinged to the outer housing. During the Drying process is the laundry lot in the manner of a chamber vice versa The inner drum is kept rotating to loosen up the laundry and the laundry items of the laundry item as evenly as possible to the current exposed to the drying air.

In the known single drum machine, the individual process steps run the drying process in the same inner drum one after the other. There are which is essentially shaking the previously drained inside drum imported laundry, their heating up, their full drying and that before cooling necessary to remove laundry. Cooling down is for safety found necessary because the drying process with up to 150 ° hot air is carried out and only after the cooling process a safe handha  laundry. The door for laundry removal may therefore only be removed be opened after cooling to a safe laundry temperature can. After loading with the new batch of laundry, the dryer becomes like the heated up. All of this means loss of time and energy.

The invention has for its object a drying device type mentioned so that the drying process largely continuously and avoiding disadvantageous loss of time and energy expires. This object is solved by claim 1.

The solution shown is based on its basic design comparable to that usually already found in large industrial laundries used car washes, in which the individual process steps in behind mutually connected drums run off. But this is an application of the Conveyor systems usual for washing machines to push the individual Lots of laundry from one chamber to the next chamber are not possible. The too Drying laundry is found in large industrial laundries dehydrated the drying process. The drainage takes place in, for example a press. Then the laundry to be dried is in the form of a compress press cake. Even after it is loosened, the use of Washing facilities tested conveyor systems for the passage of the laundry Schepostens not possible due to dryer chambers lying one behind the other Lich, because the dried laundry takes up a much larger volume than Wet wash. The sliding vanes or commonly used in car washes An Archimedean screw is therefore an analogue funding designed drying process in a drying line unusable. Au In addition, sliding blades or an Archimedean screw can be used as a conveyor tel for a dryer line designed roughly analogously to a car wash be used because the air is very easily washed up by the air Swirling dryer chamber to dryer chamber and thus the individual laundry batches of cheeses or laundry items could be mixed.  

In the solution according to the invention, each batch of laundry or each is Linen items in the drying phase in a self-contained, from the Adjacent chamber separate inner drum chamber, the principle of which one Single drum machine or a single drum dryer of the conventional type equal. The rotary drive is used for the further conveyance of the individual items drum stopped when the sliding half-shell is approximately at its bottom ren dead center position. As a result, the laundry collects within the lower half shell. Then we move the lower half-shell towards "unload", d. H. forward in the conveying direction or in the direction of flow by one chamber width pushed. This will simultaneously position the one in each compartment below Half-shell laundry items lying in the chamber following in the conveying direction advanced. In addition, this means that the lower half-shell stands with its on Front unloading end adjacent compartment freely over the inner drum or out of the machine.

Now the inner drum is turned half a turn. The advanced, lower half-shell rises and is then above the other, undisplaced Half-shell positioned. As a result, the ge lying in its unloading compartment falls dried laundry e.g. B. on a conveyor. At the same time, they fall into the insert the rear compartments of the half-shell, which has been turned up and pushed forward items of laundry in the corresponding compartments of the others, now lower and undisplaced half-shell. In this new one Rotary position is the now empty, rearward in the conveying direction compartment of the half-shell, which has remained undisplaced and is now positioned at the bottom free and is therefore ready for the loading or filling of a new one Laundry items.

After the unloading and reloading has been carried out in this way, the pre-shifted and half shell positioned above pushed back until both half shells completely cover themselves again and all of their corresponding compartments each other in a mutually assignable manner Form drum chambers.  

Now the new drying process is started. There is a renewed opening heat the loosening and heating chamber filled with new laundry and the drying chamber connected in the direction of flow is not necessary, because they haven't been cooled down before. Cooled down and perma Only the one adjacent to the unloading side, i.e. in the direction of conveyance, is used chamber, whose after cooling and turning off the rotary drive bes lower half-shell with its unloading compartment to the unloading side so far is pushed forward that the unloading compartment with initially upward Unloading opening is exposed. The inner drum is then turned half a turn turns. This causes the lower half-shell to rise and become around the inner drum salmon turned. As a result, your filler opening swivels down and the inlet Due to their inherent weight, the dried laundry drops out of the unloading compartment z. B. on a conveyor belt.

The further invention relates to the management, treatment and distribution of the Subject matter of the invention used for drying fresh air until recirculation as exhaust air into the ambient air of the drying device or into the free atmosphere sphere. It is the subject of claims 10 ff.

The invention is described with reference to the figures, for example. In it show:

Fig. 1 is a schematic cross section through which by means of a rotary drive (not shown) in rotation around your imaginary, perpendicular to the image plane longitudinal axis drivable inner drum.

Fig. 2 is a longitudinal section through the essential parts, that both the interior and through the outer drum of the drying device in their usual for the drying process relative position and in specific matically simplified form according to the section line II-II in FIG. 1.

Fig. 7 is a schematic representation of the air flow of the drying device in longitudinal sectional view.

Fig. 8, the air duct for the drying air similar to a flow diagram in cross section according inner drum chambers 7 shown the sections VIIIa-VIIIc in Fig..

The core of the drying device is the inner drum 1 . It is formed by two independent half shells 2 , 3 each extending over approximately half the drum circumference. The half-shells 2 , 3 each have the outline shape of a tube section which is approximately halved in its longitudinal direction and has a relatively large tube diameter, the ends 4 , 5 and 6 , 7 of the two tube sections halving each being closed by end walls 9 running at right angles to the tube axis = drum axis of rotation 9 wherein the tubular jacket or the two half-shells assigned to the half-shells 2 , 3 are perforated. The holes 8 of the tubular jacket are shown schematically. They are used for free, in a manner known in a drum dryer, radially to the drum rotation axis 9 directed flow through a drying chamber enclosed by the perforated jacket with drying air. The drum axis of rotation 9 , which runs perpendicular to the plane of FIG. 1, does not appear within the inner drum 1 or within half of its halves 2 , 3 . In the inner drum area it is only imaginary. The inner drum 1 is namely rotatably mounted on its outer circumference between support rollers 10 within an outer drum 11 serving as a stationary housing jacket. The outer drum 11 serves in addition to the position of the inner drum 1 also for air guidance for moisture removal.

The half-shells 2 , 3 are by a not shown, only on one of the two half-shells - here the half-shell 2 - acting displacement drive in the axial direction 12 relative to each other. The axial displaceability of the half-shell 2 is symbolically indicated in FIGS. 2, 3, 5 and 6 by a double-directional arrow drawn in the middle compartment 13 of the half-shell 2 . In addition, the interior of each half-shell 2 , 3 between the end walls 4 , 5 and 6 , 7 is divided into three compartments 12-14 (inner drum 2 ) and 15-17 (inner drum 3 ) of the same compartment size. The compartments 12-14 and 15-17 lie next to each other in the axial direction and in the direction of the drum axis of rotation 9 . In the in Fig. 2 and Fig. Shown full overlapping position 6 between the two half-shells 2, 3 which are diametrically opposite compartments of the half-shells 2, 3 together in each case an inner drum chamber, the half-shells 12 form, 15 form the inner drum chamber 18, the Half shells 13 , 16 the inner drum chamber 19 and the half shells 14 , 17 the inner drum chamber 20th This is the case in the normal position of the two half-shells 2 , 3 relative to one another ( FIGS. 2 and 6), in which the actual drying process is fully drawn and in which the inner drum 1 formed from both half-shells 2 , 3 is driven in rotation and thereby is exposed to the air flow from drying air, the course of which is described in more detail below.

Loading and unloading the drying device with individual laundry items and passing them through the compartments 12-14 and 15-17 separated by means of radial partition walls 21 , 22 and 23 , 24 of the half-shells 2 , 3 and the unloading of one Dried laundry items are described in detail below, in particular with reference to FIGS . 3-5:
The loading of the drying device with a laundry item 25 takes place from the loading side 27 which is at the rear with respect to the passage direction 26 to the removal or ejection side 28 at the front for the dried laundry item 25 .

When loading as in the removal or during ejection, the two half-shells 2 , 3 in the axial direction, ie in the longitudinal direction of the drum axis of rotation 9 by a compartment or drum chamber width against each other in the manner ben. The axially fixed half-shell 3 located in its bottom dead center position is at the rear with its loading compartment 12 beyond the end wall 6 facing the loading side 27 of the shifted half-shell 2 located in the top dead center position ( FIG. 5). As a result, the loading compartment 12 of the lower, undisplaced half-shell 3 is freely accessible from above within the outer drum 10 . Therefore, the loading device designed in the exemplary embodiment as a conveyor belt 29 can move freely into the space surrounded by the stationary external drum 11 above the loading compartment 12 of the unshifted lower half-shell 3 and deliver a laundry item 25 . This falls from above in the direction of the arrow 30 into the loading compartment 12 of the axially immovable, that is to say axially fixed, half-shell 3 which is in its bottom dead center position. This item of laundry 25 is in the form of a dewatered press cake as it is transferred from a dewatering press to the conveyor belt 29 .

After loading the loading compartment 12 of the axially fixed lower half shell 3 , the upper inner half 2 is retracted in its full overlap position relative to the lower, axially fixed half shell 3 against the passage direction 26 . In this complete overdec position shown in FIG. 6 between the two half-shells 2 , 3 , the inner drum 1 formed from them lies completely within its casing by the outer drum 11 . It is the normal relative position between the half-shells 2 , 3 , within which the individual stages of the drying process take place. In this position, the end compartment 15 of the above axially displaceable half shell 2 facing the loading side 27 supplements the loading compartment 12 of the axially fixed half shell 2 below to form an all-round inner drum chamber 20 . The same is the case with respect to the adjacent inner drum chamber 19 in the direction of passage 26 , which is formed by the overlapping central compartments 13 , 16 of the two half-shells 2 , 3 . Furthermore, this is the case in an analogous manner with respect to the front inner drum chamber 20 , which is formed by the inner drum chambers 14 , 17 through the mutual overlapping position. In this normal position shown in FIGS . 2 and 6, the actual drying process takes place and since the inner drum 1 with its two half-shells 2 , 3 is rotated in the direction of rotation 31 about the inner drum axis 9 within the outer drum 11 . In addition, the inner drum 1 is blown by an essentially radially directed ge, inside the jacket of the outer drum 11 air flow of dry air. The air flow is described in more detail below with reference to FIGS. 7 and 8.

Within the inner drum chamber 18, which is located at the rear with respect to the direction of passage 26, the inner drum 1 is rotated in the dry air stream, and the shaken and heated laundry item 25 is heated.

The middle, also filled with a laundry item 25 Innentrommelkam mer 19 serves the actual drying process at a drying temperature up to about 150 ° C. The inner drum chamber 20 which faces the ejection side 28 and which is at the front in the passage direction 26 is the cooling chamber in which the dried laundry item is cooled to a temperature which no longer means any danger for manual handling of the laundry. When the inner drum 1 rotates in its adjacent chambers 18-20 , the shaking and heating (chamber 18 ), drying (chamber 19 ) and cooling (chamber 20 ) of a laundry item 25 take place at the same time.

To remove a dried and cooled laundry item 25 , the rotary drive of the inner drum 1 is stopped in the bottom dead center position of the axially displaceable ren shell 2 . Thereafter, the lower half-shell 2 is first advanced in the passage direction 26 relative to the upper half-shell 3, which is axially displaceable within the outer drum 11 . Then the Entnah meabteil 14 is open uncovered up ( Fig. 3). While maintaining this open position, the inner drum 1 is then rotated clockwise by a half turn (direction of rotation 31 ). The transfer of the axially displaceable half-shell 2 into an overlying position relative to the other half-shell, as shown in FIG. 5, is thus synonymous. Fig. 4 indicates an intermediate position between the rotational positions according to Fig. 3 (starting position) and Fig. 5 (end position) of the ejection process. When the axially displaced half-shell 2 is swiveled up from its initial position shown in FIG. 3, a catch device 32 simultaneously moves into the space now released below the unloading compartment 14 . The collecting device is effective in the manner of a receptacle into which the dried laundry item 25 falls downward in the direction of arrow 33 from the swung-out removal compartment 14 ( FIG. 4). The collecting device 32 is expediently connected to a conveying device which supplies the dry laundry to a next processing station (not shown). The ejection end position shown in FIG. 5 is at the same time the loading position for the new loading of the loading compartment 12 at the rear end of the drying device.

The invention now makes it possible to divide the drying process, which was previously only fully drawn from heating to cooling within a single inner drum, into several individual steps, which are carried out step by step in the direction of passage 26 side by side. As a result, it is not necessary dig to heat the inner drum 1 one after the other, to add the drying heat and then to cool it down again for unloading and receiving a new laundry batch. In the exemplary embodiment, three inner drum chambers 18-20 are arranged next to one another in the same inner drum. In principle, it would already be advantageous compared to the conventional single-drum machine to work according to the invention with only two inner drum chambers 18 , 19 arranged next to one another. It is also conceivable, instead of existing in the exemplary embodiment in the normal position a total of three nebeneinan commonly the inner drum 1 forming the inner drum chambers provide 18-20 more than three inner drum chambers adjacent to each other and thereby the drying process from the feed side 27 to the ejection side 28 in more than three individual steps to make without changing the principle of the invention. This is based on the division of the inner drum 1 into two half-shells 2 , 3 which, in addition to the conventional drum rotation, also enable an axial relative displacement relative to one another in that one half-shell 2 is axially displaceable relative to the other, axially fixed half-shell 3 . This enables a step-by-step passage of the laundry in the axial direction through the drying device while maintaining its batch-wise introduction.

The air routing inside the drying facility enables special energy savings. It is particularly effective in the normal position of the inner drum 1 shown in FIGS . 2 and 6 and 7 and 8, ie outside the loading or unloading and ejection phase of the drying process. It is described in more detail with reference to FIGS. 7 and 8.

Each inner drum chamber 18-20 is struck or flowed through by an independent air flow which, as the passage direction 26 in the form of a counter-air flow, starting from the fresh air 35 extracted from the ambient air, initially through the cooling chamber 20 serving to cool the dried laundry item there through the Trocknungskam 19 and finally passed through the heating chamber 18 before the counter-air flow by means of the heat exchanger 36 removes the inherent heat and then it is returned to the ambient air or outside atmosphere as exhaust air 37 .

The introduction of the counter air flow into an inner drum chamber 18-20 as a chamber air flow 38 , 39 or 40 takes place in the clockwise direction of rotation 31 of the inner drum 1 approximately in the 7 o'clock position ( FIG. 8) on the inside of the outer drum 11 in a diametrical direction to the drum rotary axis 9 . This blowing-in direction for the dry air means that the dry air is drawn off in approximately the 1 o'clock rotary position from the peripheral region of the rotatingly driven inner drum 1 on the outer jacket of the outer drum 11 and is essentially passed on to the 7 o'clock peripheral region of the inner drum chamber adjacent in the counterflow direction .

A special feature is that the supply air 38-40 does not consist entirely but only partially, namely only roughly approx. 40% of the counter-air flow originally fed by the fresh air 35 . For the most part, roughly 60%, the supply air flow 38-40 to one of the inner drum chambers 18-20 consists of circulation air. This distribution of quantities is currently still based on theoretical considerations, which, however, can still be determined more experimentally and through empirical values to be acquired in practice. They will also depend on the quality of the dewatering press upstream in the laundry flow of the drying device according to the invention, that is to say on the water content within the laundry item fed to the loading side 27 . Another criterion is the quality of the laundry material to be dewatered, i.e. the textiles (cotton or e.g. blended fabrics).

To branch off the circulating air, the counter-air stream is blown after passing through an inner drum chamber 20 , 19 and then 18 in the region of a fork-shaped line division 41 , 42 or 43 into a circulating stream 44 which is returned to the inner drum chamber 20 , 19 or 18 through which flow has already taken place , 45 or 46 and into the further counter air flow, which is carried on to the next inner drum chamber and finally to the exhaust air 37 . The air volume distribution into the recirculated circulation flow 44-46 on the one hand and the further counterflow to the exhaust air 37 on the other hand takes place through valves 47 in the respective flow paths. A filter 48 , 49 or 50 is connected upstream of the respective line division 41-43 . In addition, a fan 51 , 52 and 53 is used in the line path of the countercurrent behind each inner drum chamber 18-20 , which ensures the flow pressure or flow generation.

The heat extracted by the heat exchanger 36 from the exhaust air 37 is fed to the heat exchanger 54 , which is assigned to the counter-air flow before the drying chamber 19 and heats it up. In addition, the drying chamber 19 and the heating chamber 18 supplied chamber air flow 39 or 40 heat is supplied by external steam 55 or 56 , as it is basically available in industrial laundries for heating purposes in particular for the washing water.

Starting from the ambient or fresh air 35, the counter air flow takes the following course: The fresh air 35 is fed completely to the chamber air flow 38 to the cooling chamber 20 . However, it only feeds about 40% of the chamber air flow 38 to the cooling chamber 20 . About 60% of this chamber air stream 38 is fed by the circulating air 44 added, which is taken from the counter-air stream behind the cooling chamber 20 , namely in the area of the line portion 41 is branched from the latter.

Behind the chamber outlet 57 , the counter air flow passes through the filter 48 and the flow is accelerated by the fan 51 . The temperature level of the chamber air flow in the cooling chamber 20 is during the cooling process from approximately 80 ° at the beginning to approximately 30 ° at the end, as shown in FIG. 8.

The branched-off through the line division 41 and the drying chamber 19 is directed to counter air flow quantity about 40% of the exhaust stream from the cooling chamber twentieth However, this counterflow amount only contributes to about 40% of the total amount of the chamber air stream 39 fed to the drying chamber, which is fed to about 60% from the circulation air 45 which branches off from the chamber air of the drying chamber 19 in the region of the line division 42 . The chamber air flow 39 is heated by external steam 55 to a drying temperature of approximately 150 °. This is the temperature level reached in the drying chamber 19 during the drying process approximately at the end of the drying process. Behind the drying chamber 19 , the counter air flow again flows through a filter 49 and it is accelerated by a fan 52 . About 40% of the exhaust air flow from the drying chamber 19 is branched off in the region of the line division 52 and directed further in the direction of the heating chamber 18 . Here, however, this counter air flow in turn forms only about 40% of the total amount of the air flow 40 that is supplied and heated by external steam 56 to a temperature of 150 °. It flows through the heating chamber 18 and heats up the laundry item 25 contained therein. Behind the heating chamber 18 , the exhaust air in turn flows through a filter 50 and it is accelerated by the fan 53 . 40% of the exhaust air is passed through a further filter 58 and pressed through the heat exchanger 36 by means of a fan 59 and fed to the exhaust air 37 . The heat extracted from the exhaust air flow in the heat exchanger 36 is supplied to the heat exchanger 54 for heating the supply air flow to the drying chamber 19 .
