The inventor of CARLSSON ERIC HARALD ing., ANGELHOLM (Sweden) and the proprietor of the patent (54 J Apparatus for drying the substance and contacting the drying agent 1)

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for contacting a dried substance with a drying agent, for example a semi-solid or solid material with a drying gas, that is to say substantially a dryer, similar to the dryer of British Patent No. 1,265,719.

British Patent No. 1,265,719 discloses a new and high performance dryer. This dryer has a very large field of application, which includes in particular the drying or thickening of liquid, semi-solid and rigid materials. However, this field of application is not limited to self-drying, but also involves contact between two fluids, such as contact between liquid and gas, contact between two gases, and contact between two fluids for chemical reactions. According to the present invention, it should not be forgotten that the liquid and semi-solid materials are dried. The prior art apparatus does not allow efficient feeding of the material for drying and efficient separation of the processed material. Also, the processing of materials with significantly different structures and densities in one and the same drier has not yet been possible without significant variations in the individual devices.

The drawbacks of the prior art 202027 2 are now removed by an apparatus for bringing a dried substance, such as a liquid semi-solid or solid material, into contact with a desiccant, e.g. a plurality of spherical contact lenses, which are guided in a circulating tank along a path having in said follow-up region a material which is to be entrained on the contact body, the main drying area lying in the upper a portion of a backing bed, a peripherally disposed drying chamber, a landing area disposed in the bottom of the backing bed, and a separating area provided below the backing surface to peel the finished material away from the contact bodies, wherein the separation zone a perforated bottom that passes through the finished material, but does not retains the contact bodies to return them to the material discharge area by means of a centrally located conveyor which surrounds the downwardly extending sleeve against the perforated bottom, according to the invention, the base of which is that the sleeve the surrounding screw conveyor is rotatable relative to the worm conveyor, the discharge area of the conveyor has discharge members which are disposed at the upper end of the conveyor worm 202027 34 and with the rotary sleeve of the worm conveyor have the dispersing arms mounted so that the worm conveyor at its the lower end of the separating member, which consists of rotatable feeder arms which are mounted on a rotatable sleeve of the screw conveyor for co-running and handing contact bodies of the lower portion of the support bed on the inner and below feeder arms, the gap being formed the inner separating rotor, which is connected to the shaft conveyor for co-circulating, and the outer stationary separating station, which is located under the gap with the inner separating rotor. In order to improve the separation of the finished material from the contact panels, the rotor plate separator rotor has a stator plate separator stator projecting into the gap. In the treatment of a material which tends to be smudged when heated, the gap of its upper periphery is provided with a feed gas channel.

To process the liquid material, the discharge members consist of a dampening container arranged on a rotatable sleeve and arranged around it from a rotatable liquid receiver connected to the worm shaft, which liquid receiver is folded down into the dampening container for introducing the substance to be dried from the rotating spiral arms connected to the worm shaft for circulation and movement of the contact lenses against the outer edge of the dampening vessel and the rotating diffuser arms associated with the outer periphery of the dampening vessel extending to the outer wall of the dispersing tank contact bodies coming from the dampening vessel through the support bed in the tank. The liquid collector consists of a collecting vessel arranged around the screw conveyor shaft and outflow tubes extending downwardly of the collecting vessel.

According to a further feature, the substance discharge members comprise feeders of an insert substance to be dried through the upper hollow shaft of the screw conveyor to the distribution tubes provided on the lower part of the upper hollow part, of the first and second mixing arms provided for the upper portion of the screw conveyor for mixing the first substance, discharged from the distribution bodies with the contact bodies, of the dampening vessel, located on the rotating sleeve and the extending wheel, of the spiral arms, connected by the shaft of the screw conveyor and extending into the dampening vessel, of the distribution pipes associated with a dampening vessel, and a circular cap closing the dampening vessel extending from the worm conveyor shaft to the ducting tubes.

In a particularly advantageous embodiment, the feeder consists of an auxiliary screw conveyor, which is located in the upper hollow part of the shaft of the screw conveyor, and the first and second mixing arms are located on the upper part of the shaft of the screw conveyor or the sleeve.

To process the solid material, the fabric entraining members consist of a dampening container disposed on a rotatable housing extending around it, of the rotatable diffuser arms connected to the outer periphery of the dampening container and extending to the outer wall of the container for distributing contact bodies coming in from the dampening vessel through the base bed in the tank, from the spreading container for the substance to be dried, placed between the outer edge of the dampening vessel and the wall of the tank as well as above the base, which spreading carriage has a bore and a rotary cone arranged therein. to extend the cylinder to rotate the center of the tank along the path above the bed, preferably in front of the diffuser arm when viewed in the direction of rotation.

To process the material that is cut into pieces by gas, the discharge member comprises a distribution tube located at the top of the screw conveyor by a rotating sleeve, from the discharge spiral arms located at the top of the screw conveyor shaft. for discharging the substance to be dried and the contacting bodies of the distribution tube, from the cylindrical housing around the top of the shaft of the worm conveyor extending the lid, located by the guide tubes and discharge spiral arms having the insert arm to be dried, and insert members for inserting the substance to be dried into an insertion space surrounded by a lid. The device according to the invention allows for efficient feeding of the material for drying and no less efficient separation of the final processed material. Thus, the invention makes it possible to process materials with significantly different density in one and the same drier, with only minor variations. This has not been possible yet. Furthermore, the construction of the dryer according to the invention also permits a satisfactory and reliable operation of very large apparatuses.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of an apparatus for contacting a desiccant with a desiccant according to the invention; FIG. 2 is a vertical sectional view of the apparatus of the present invention; Fig. 3 is a cross-sectional view of the apparatus of Fig. 2, taken along the line III-III of Fig. 2; FIG. 7 is a cross-sectional view of a rigid material feeder; FIG. 8 is a vertical sectional view of another embodiment of the apparatus of the present invention; with a feeder for semi-rigid and viscous material; FIG. according to the invention, with feeders for fine material.

The dryer of the embodiment shown in FIG. 1 has a fan 2 driven by a first motor 1 and connected to a main pipe 3 with an air filter 4 and a heat exchanger 5. in which the air circulating through the main tube 3 can be heated to an appropriate temperature. The heat exchanger 5 may be discharged if a highly sensitive material is to be processed so that the air at room temperature or lower temperature then flows through the main pipe 3 to the tank 6 of the drying apparatus according to the invention. channel 7 arranged around the tank 6 and interconnected with its interior. The lower part of the tank 6 is connected through a first tube 8 to a series of cyclones 9, which, if a dried substance is to be recovered from the liquid, as in the illustrated drying device, serves to separate the dry substance from the drying device. The air which escapes into the atmosphere through the air tube 10 and the suction fan 12 driven by the second motor 11. The drying air, saturated with the liquid vapor vapor, also leaves the tank 6 through the second tubes 13.

If a complete enclosure is required or necessary, for example for the treatment of very odorous or poisonous substances, the drying air or gas leaving the tank 6 through the second pipe 13 is recirculated to the fan 2 as shown in Fig. 1.

The drying apparatus of Fig. 2 is a schematic of the British Patent Specification No. 1,265,719 and details common to both apparatuses, such as contact bodies, will be described briefly. In addition, the drying apparatus of FIG. 2 will be described with respect to liquid drying.

The drying apparatus according to the invention has a tank 6 with a plurality of spherical contact portions 14, in particular of plastic materials. A worm conveyor 16 driven by a third motor 15 is arranged in the middle of the tank 6 and serves to move contact bodies 14 from the bottom of the tank 6 to its upper part. During operation, the contact bodies 14 are continuously moved by the worm conveyor 16 upwardly within the middle portion of the tank 6 and downwardly fall by gravity along the wall 6 which surrounds the middle portion with the screw conveyor 16. The material to be dried is fed by one or more The drying gas is fed through a peripheral channel 7 which extends around the periphery of the tank 6 and is connected through openings in the tank shell 6 with the air radial channels 18. The dried material is discharged through the first tube 8 (FIG. 1). The saturated drying gas leaves both the first pipe 8 and the second pipe 13 (FIG. 1). From a working point of view, the drying device is divided into four zones, namely the strip of dried material, the main drying zone, the drying zone and the separation of the dried desiccant material. In the depicted device, a feed tube 17 is provided in the feed zone of the dried material which feeds the liquid or sludge, the intended drying, into the bowl-shaped liquid receiver 19 provided with downwardly directed discharge tubes at its edge and a shaft of the shaft arranged The discharge tubes are terminated by a tightly moistening vessel 20 which is mounted outside the housing 21 of the screw conveyor 16. The screw conveyor 21 of the screw conveyor 16 is arranged rotatably around the screw conveyor 16 by means of a sprocket 22, a chain 23 and a fourth motor 24 ( Fig. 3). The rotation is adjusted in such a way that when the screw conveyor 16 is rotated in one direction, the housing 21 will rotate in the opposite direction. The rotational speeds are not critical, but can be varied according to convenience. In addition to the discharge pipes of the liquid collector 19, a pair of coil arms 25, connected by a shaft of the screw conveyor 16, intervenes in the wetting vessel 20. The liquid collector 19 and the spiral arms 25 serve to liquidate the feed pipe 17 into the wetting vessel 20 without contacting for example, with the upper side of the spiral arms 25 on which a thick layer of dried liquid would otherwise be deposited. In the dampening vessel 20, the liquid comes into contact with the contact bodies 14 which have been introduced into it by the screw conveyor 16. The contact bodies 14 are inverted by the action of the spiral arms 25, so that the contact surfaces of the contact bodies 14 are completely in contact with each other. forming a uniform layer of liquid, and the contact bodies 14 are then guided towards and beyond the o-region of the dampening container 20 where the scatter arms 26 are arranged. The scattered arms 26 extend from the inner wall of the container 6 to the outer edge of the dampening container 20 and attached to the dampening vessel 20, as a result of which they are rotated therewith. The scatter arms 26 serve to disperse the contact bodies 14 in a uniform layer on the support bed 27 without forming a flow angle.

The second zone, which is the main drying zone, starts at the base bed 27 from the coated contact bodies 14 and includes the upper portion of the base bed 27. In the main drying zone, contact bodies 14 moving downward through the drying gas stream meet. controlled by the upstream of the air radial channels 18. This countercurrent transport of the contact layer 14 and the drying gas provides maximum drying in the main drying zone. The zone of main drying and in the lower part of the base bed 27, or below the introduction point of the gas from the air radial channels 18, starts the drying zone, as indicated by the name of the material bound to the contact 202027 of the body 14. the main drying, the gas in the drying zone is conducted in parallel with the contact bodies 14, thereby allowing the last drying stage to take place the least.

This is especially important if it is desired! avoid overheating of sensitive materials, such as foodstuffs and the like. Subsequently, the contact bodies 14 come into the fourth and last zone, i.e. into the drying zone of the dried material, which is located in the lower part of the tank 6 and in which the dried material is separated from the contact bodies 14, which are then returned to the material transport belt by a screw conveyor 16 for the next drying cycle.

As can be seen from FIG. 2, the desiccant separation zone consists of a plurality of cooperating cells, first of which are two feeder arms 28, located in the lowermost portion of the support bed 27 and directly above the taper at the tank 6. 3, they may have a top view 28, seen from above, of a helical face, which extends from the center of the container. The height of the inlet opening of the supply arms 28 is substantially constant, as shown in Fig. 2, and corresponds to a factor of two to five times, preferably three times the total diameter of the contact bodies 14. This dimension has proved to be This reduces the entrapment of the spherical contact bodies 14 with the guide arms 28. The tapered constriction with the separator rotor 29, located centrally in the lowest part of the tank 6, produces a relatively narrow circular slot, which moves the contact bodies 14 through the guide arms. 28. In order to completely separate the dried material from the contacting bodies 14, the separation rotor 29 in the gap is provided with rotor plates 30 which engage said gap and are made of stainless steel or other lower material, and furthermore, the constriction is formed as a separator stator31 which is similarly to the separating rotor 29, it is provided with stator plates 32, which engage in said gap. The separator rim 29 is connected to the worm shaft 16 and is formed as a cone of the outer wall of the worm conveyor housing 21. Experiments have shown that the effective radial distance of the gap axis from the center of the drier is between 0.5 and 1 meter since a greater distance would result in unacceptably high circumferential speeds of the rotor plates 30a of the separator rotor 29. It should be borne in mind that this relates to a rotational speed of about 10 to 40 rpm of screw conveyor 16 and that at other speeds, other values are. Under the aforementioned gap, a perforated separating bottom 33 is arranged which is shaped to allow the passage of the dried material and to retain the contact bodies 14 released from the dried material. The clean contact bodies 14 are then transported upwards into the material feed belt by a screw conveyor 16 which reaches down to the perforated separating bottom 33.

The separation device operates on the basis of the following principle. In the lower portion of the base bed, the contact bodies 14 with the layered material pass substantially already in a dry state co-current with the drying gas to the supply arms 28. The contact surfaces 14 are captured by the feed radii 28 and moved towards the center of the receptacle 6 towards the circular separator gap. As they pass through the aforementioned gap, the contact bodies 14 are brought into perfect mutual friction on the one hand and on the other side of the orotor and stator plates 38 and 32, which fall into the gap and rotate one second, thereby completely and quickly removing them. the dried material from the contact bodies 14. This removal is further facilitated by a strong gas stream which reduces the space in the space and entrains any loose flakes of dried material and ensures the named material moves in a predetermined direction through the perforated separating bottom 33k. The first tube 8 for conveying to the cyclone separator 9 shown in FIG. 1. By suitable control of the blower fan 12 and the blower 2, the gas flow and hence the temperature in the tank 6 and the separation gap can be adjusted to the desired value.

The dryer shown in FIG. 2 has an additional channel 34, which is provided by a wheel of the lower cylindrical portion of the tank 6 and connected by said circular separating gap. The auxiliary channel 34, without which it can be bypassed in most cases, serves to supply the cooling air to avoid any tendency to stick to the materials exhibiting said heating tendency and to facilitate the separation of the finally dried material.

FIG. 4 shows another arrangement of the feeders which is intended in particular for feeding semi-solid or doughy material. In order to provide sufficient contact between the material to be fed and the contact bodies 14 and to provide a layer of material to the surface contact bodies 14, the arrangement is such that the material being introduced is brought into contact with the contact bodies 14 at a distance from the screw conveyor 16 For this reason, the shaft of the screw conveyor 16 in its upper portion 35 is hollow and there is an auxiliary screw conveyor 36 driven by the fifth motor 37 within the shaft portion 35. In the illustrated device, the hollow shaft of the screw conveyor 16 is shaped at its upper end as a receiving hopper 38 for a material to be dried and at its lower end has a distributor pipe shaft 39 through which the material is discharged into the space between the screw conveyor 16 and its housing 21. As shown in FIG. ends at the screw conveyor 16 in the region of the distributors The pipes 39 are a mixing zone 40 with the first and second mixing arms 9, 10, 202027, 41, 42 which are attached to the shaft of the screw conveyor 16 and to the inner wall of its housing 21, each separately. This first and second mixing arms 41, 42 contribute to bringing the dried material into contact with the contact bodies 14. As the dryer of FIG. 2, the dryer shown in FIG. 4 is provided with a dampening container 20 at the upper end of the housing 21 of the screw conveyor 16. is arranged around said housing 21, the advancing rotatable spiral arms 25, which engage the dampening vessel 2D. 4, as in the embodiment of FIG. 2, are connected to the shaft of the screw conveyor 16 and are adjusted to rotate to move contact contact 14 towards the edge of the wetting container 20. In order to provide effective the dispersion of the coated contact bodies 14 on the lower support bed 27 is provided with a distribution tube 43 attached to the edge of the moistening container 20 according to FIG. 4. In addition, the manifolds 43, as above, may exhibit a slight curvature of the rearward direction of rotation. In order to obtain a positive supply of the coated contact pads 14 through the distribution tubes 43, the moistening container 20 is provided with a lid 44 which can be removed for inspection and repair purposes.

FIG. Figures 5, 6 and 7 show a further example of the arrangement of the feeders, in particular for providing and distributing solid material, for example grass. As in FIG. 2, the dryer is provided with a screw conveyor 16, a housing 21, and a dampening vessel 20, which is arranged around said housing 21, and one or more dispersion arms 26 attached to the dampening vessel 20. However, when the material to be dried is solid, the contact bodies 14 do not come into contact with the feed material in the humidification period 20, as is the case with the apparatus of FIG. Instead, the contact is achieved only when the contact bodies 14 are dispersed through the base bed 27. For this reason, the lance 17 and the fluid cutter 19 of FIG. 5 have been replaced by a spreading carriage 45 which is positioned above the bed 27 and constructed to be a rigid dried material such as grass, spread evenly over the backing bed 27 through a conical spreading roll 46 which is mounted on the bottom of the spreading carriage 45. This spreading carriage 45 is attached to the dampening vessel 20 so as to rotate it around to rotate, the spherical spreading roller 46 is provided at its end facing the wall of the tank 6 with a toothed wheel that engages the respective teeth arranged around the periphery of the tank 6 and is mounted to the wetter in the second end. distribution of the material over the substrate 27, the opening in the bottom of the spreading carriage 45 and the spreading roller 46, corresponding to said opening, is conically tapered towards the center of the tank 6. The spreading roll 46 shown in the drawings has nails, but it is self-evident that using other types of rollers suitable for distributing solid or piece material. Furthermore, it is also understood that instead of one spreading roller 46, the spreading carriage 45 may have two or more named spreaders which travel along the marked path along the backing bed 27. In order to achieve the desired layered structure In the lower layer shown in FIG. 6, the diffuser arm 26 should be rotated immediately downstream of the spreading carriage 45 in order to prevent distributed light material, such as grass, raising and entraining upwardly flowing gas passing through it. the base bed 27.

The dryer shown in FIG. 8 is designed for viscous materials and substantially corresponds to the dryer shown in FIG. 4. However, the dry material feeders are somewhat simplified compared to the arrangement of FIG. Instead, the material is fed directly through the third pipe 47 which is connected to the hollow portion of the shaft of the screw conveyor 16. The material is guided by the third pipe 47 into the hollow upper portion 35 the worm conveyor shaft 16 and the diverter pipe 39 of the worm feeder.

FIG. 9 shows the arrangement of the feeders of the feed material particularly useful for feeding into pieces of chopped products and under. As with the driers shown in Figures 2 and 4, the worm conveyor 16 is provided in its upper portion with spiral arms 25, which discharge a mixture of contact bodies 14 and pieces cut with material through the ducts 43 associated with the rotations. a housing 21 of the screw conveyor 16, which is arranged around said screw conveyor 16. A lid 44 is provided above the discharge spiral arms 25 and the distribution tubes 43, which extends upwardly in the shape of a cylindrical housing and closes the space , into which the chopped material is fed through the inserting element 48, for example by a screw feeder.
