Definitions

  • the present invention relates to the drying of spreadable materials in a bed, in particular fodder, with a large flow of air. It more specifically aims to reduce the cost of equipment by allowing the installation of drying in low installations in which the drying beds are coplanar.
  • the conventional installation consists in using perforated conveyor belts circulating in opposite directions, the material to be dried being brought to the upstream end of a conveyor belt and transferred to the downstream end thereof on the upstream end of the carpet flowing in the opposite direction, the gas flow passing through the conveyor belt and the bed of material which it carries.
  • the conveyor belts are superimposed and the material falls from the highest conveyor belt onto the conveyor immediately below the downstream end of each conveyor belt.
  • the degree of dryness of the material increases as it goes down in the stages. The material is in movement during the entire drying process, the transport equipment is complex and expensive and this movement does not improve the efficiency of the exchange of moisture between the material and the drying gas.
  • DE-A-3 006 126 describes a device of this type in which, in order to be able to have beds of material to be dried on the two strands of the chain, the latter consists of flaps which are released at the end of the chain close to a deflection roller to drop the material carried by the flap which opens on the other strand of the same chain or on the upper strand of the chain placed below.
  • DE-A-2 209 013 Also known from DE-A-2 209 013 is an installation in which the material is spread on an upper drying area constituted by shutters and after a first drying stage it falls on the drying area situated below and thus immediately from area to area, all of the drying areas being traversed by an ascending stream of drying air.
  • US-A-2050477 describes a similar installation, the superimposed areas each consisting of a plurality of oscillating plates with which cooperate scanning means which cause, during each oscillation, to drop the material carried on a plate of the area located in below.
  • the object of the present invention is to propose an installation for drying spreadable materials in gas-permeable beds, according to the counter-current method, which greatly reduces the investments necessary for the implementation of the previously known methods in which the material to be dried is circulated, continuously or step by step, during the drying period, in a zigzag course parallel to the largest dimension of the surface of the bed and perpendicular to the direction of flow of the gas flow drying.
  • the installation for drying materials spreadable in gas-permeable beds according to the counter-current method according to the invention which comprises a plurality of perforated drying areas arranged parallel to each other and in series along the circulation path drying gas so that they pass successively through the gas flow, with means for bringing the material subjected to drying to the upstream area which is furthest downstream in the gas flow, and means for transferring it from area to area, up to the most downstream area which is furthest upstream in the gas flow from where means evacuate it in the dry state
  • the perforated drying areas are fixed and coplanar and in that the installation includes means for bringing the material subjected to drying to the upstream area most downstream in the gas flow, means which move above said area in the greatest direction of the areas and deposit the material to be dried in successive sections of said upstream drying area and means for transfer from area to area which take the material in a section from the upstream area and transfer it to a section of the downstream area from which the material has been removed to be transferred to the area further downstream or to be evacuated
  • the transfer of the material from the upstream area to the downstream area can be achieved by a first movable chassis along the length of the upstream area and carrying a pickup device picking up across the width of the upstream area in front of the chassis and a spreading device spreading the material to be dried over the width of the upstream area behind the frame and a second frame movable along the length of the downstream area and carrying a pickup device picking up across the width of the area downstream in front of the second chassis and a spreading device spreading the material collected by the collecting device of the upstream area over the width of the downstream area behind the second chassis and means for transporting the material collected by the device of collecting the first chassis to the spreading device of the second chassis.
  • the two frames can be joined in the form of a carriage spanning the two areas and carrying the means of transport arranged transversely. It is also possible to provide two independent carriages moving in opposite directions over the areas while occupying homologous positions, the means of transport being constituted by conveyors parallel to the areas with a means of transfer from the upstream area to the downstream area located at the end of the upstream area.
  • the material can be brought to the device for spreading the upstream area and evacuated from the device for collecting the downstream area by skips carried by the movable frame of the upstream area and the movable frame of the downstream area respectively. It is also possible to provide conveyors arranged parallel to the drying areas.
  • the duration of transport of a load representing only a very small part of the total duration of the drying, handling and transport of the material to be dried are provided by a single carriage moving on rails above the various drying areas, this carriage comprising a loading platform, recovery means capable of taking up the fodder on a surface for loading it on this platform and means for spreading the loading of fodder being on this platform.
  • the two drying areas constituted by a perforated sheet or a mesh AV and AM are arranged side by side and only the parts of these areas where the transfer of the material to be dried is in progress have been schematized .
  • the AM area is the upstream area on which the fresh material is and the AV area is the downstream area on which drying ends.
  • the gas flow G in practice air which, for example, is heated by passing over the hot exchanger of a heat pump, is brought under the AV area and ascends upwards the bed of material already rid of part of its humidity carried by this area then it crosses in an ascending manner, as shown schematically by the arrows G, the bed of more humid material carried by the upstream area AM to be taken up below this area.
  • RAM designates the reservoir for supplying the material to be dried and REV designates the reservoir for discharging the dry material, an example of which will be described in more detail below but which could also be continuous conveyors such as conveyor belts transporting the material in the direction of arrow F.
  • These tanks as well as the means of distribution and recovery on the areas and of transfer from area to area which will be described schematically below circulate in the direction of the arrows F.
  • the material to be dried brought into the RAM tank is distributed over the section a 1 to constitute the bed A 1 behind the device.
  • the bed of material A 2 already half dried and which is on the upstream area AM in front of the device is taken up in section a 2 located in front of a 1 to be transferred to section a 3 of the area of AV drying to constitute the bed of material A 3 behind the device and the bed of material A 4 at the final dryness which is on the downstream area AV in front of the device is taken up to be loaded into the REV drain tank.
  • the RAM supply tank is loaded with material to be dried at the upstream end of the drying areas and the dry material is removed from the REV tank downstream from the drying areas.
  • the details of the device may vary depending on the nature of the material to be dried and a device suitable for drying the fodder will be described more particularly below.
  • the AM-AV drying areas each consist of a perforated sheet 1 carried by longitudinal beams forming rails 2 of circulation for the carriage and extended downwards by aprons to constitute supply and return air tunnels for drying.
  • the sheets 1 are reinforced by crosspieces 3.
  • the carriage frame and the rollers on the rails 2 as well as the drive means are not shown to simplify the drawings.
  • the frame carries, by bearings 4-5, two parallel axes 6 and 7.
  • the two axes are driven in the same direction shown by arrows in the figures.
  • the front axis 6 carries a hedgehog whose teeth 8 come to tangent the surface of the perforated sheet 1 so as to pick up the forage lying in bed on the area and to project it, with the help of a guide plate 9 and deflecting teeth 10, on a conveyor belt 11 disposed transversely to the carriage and the upper strand of which flows from the area AM towards the area AV as represented by the arrow F 1 .
  • a sheet 12 across the width of the AM area prevents the material from being projected beyond the conveyor.
  • the rear axis 7 carries a hedgehog equalizing the bed, the teeth 13 of which are spaced from the sheet 1 of the thickness of the bed.
  • a chute 14 Behind the sheet 12 and in front of the hedgehog 13 opens a chute 14 whose rear edge is extended by deflecting teeth 15 interposed between the teeth of the hedgehog 13.
  • the chute 14 is located at the base of an enclosure 16 forming a reserve of spreadable fodder for a start of drying on the upstream area AM.
  • a conveyor belt 17 At the bottom of the enclosure and over its entire width is mounted a conveyor belt 17 provided with teeth 17a which paint the base of the load and bring the material to the opening of the chute 14, the material being deflected towards the chute by deflecting teeth 18.
  • the axis 6 carries the return cylinder 19 of a lifting belt 20 provided with projecting teeth 21.
  • a deflecting plate 22 cooperates with the lifting belt 20 to prevent the dried material being found on the AV area and taken up by the teeth 21 of the lifting belt, falls back on said area.
  • the material is projected by centrifugal force when the belt passes over the upper return cylinder 24 and it falls into an enclosure 25 intended to collect the dry material.
  • Teeth 26 which engage between the teeth 21 of the lifting belt release the material which could stuff between said teeth.
  • At the top of the tank 25 is mounted an endless belt 27 which can be driven in the direction of the arrow or lowered by jacks 28. The purpose of this conveyor belt is to spread the pile of material over the entire surface of the tank 25 and compact the material to reduce its volume.
  • the shaft 7 carries a hedgehog whose teeth 30 pass over the upper surface of the sheet 1 at a distance equal to the thickness of the bed. Deflecting teeth 31 prevent the material from stuffing around the hedgehog 30.
  • the enclosure 25 is empty and the enclosure 16 is loaded with material, for example fodder to be dried.
  • material for example fodder to be dried.
  • the truck is started.
  • the fodder beds which were on the areas are picked up by the lifting belt 20-21 for the dry fodder located on the downstream area AV and by the hedgehog 8 for the semi-dried fodder found on the upstream area AM .
  • the dry fodder raised by the lifting belt 20-21 is poured into the enclosure 25.
  • the semi-dry fodder picked up by the hedgehog 8 is projected onto the conveyor belt 11 which brings it above the downstream area AV on which it is spread by the sheet 29 and the hedgehog 30, this area having been freed from the dry fodder treated during the preceding half-period by the lifting belt 20-21.
  • the fodder to be dried being in the enclosure 16 is spread by the chute 14 and the hedgehog 13 on the upstream drying area AM which has been freed from the half-dried fodder during the preceding half-drying period by the hedgehog 8.
  • the homologous sections are symmetrical with respect to a point P located between the areas equidistant from their ends. Namely, the fodder to be dried being supplied with M and the dry fodder discharged at S, the fodder supplied with M is deposited in a section a, 'which was released during the previous cycle and the semi-dried fodder is collected in the section a 2 'close to a i ' to be spread in section a 3 'released during the previous cycle, the dry fodder in section a; neighbor being picked up to be evacuated in S.
  • the above embodiment of the method can be implemented with a trans device single carrier, pick-up and spreader, for example of the type described with reference to FIGS. 6 and 7, which moves on rails forming a circuit above the drying areas and the loading and unloading devices S.
  • the meaning of forward movement is the direction of arrow C, FIG. 5.
  • the carriage comprises bogies 41 with rollers 42 some of which are motors which carry the frame 43. Under this frame hangs a transport platform 44 at a end of which is mounted the drum 45 of a pick-up 46 whose teeth pass between bars 47.
  • the platform 44 is suspended from the frame, at the end corresponding to the pick-up, by fixed points 48 created by bars 49, fixed points around which levers 50 are articulated, one of the arms of which rotates the axis 51 of the pick-up while the other arm is actuated by a jack 52 acting between its end 53 and the frame 43 At its other end, platform 44 is suspended from the end 54 of a jack 55 articulated at 56 on the frame 43.
  • the platform 44 can thus be raised, lowered and tilted longitudinally.
  • a spreading hedgehog 57 is suspended by an oscillating bar 58 from the frame 43, the position of the hedgehog relative to the neighboring edge of the platform being adjustable by means of a jack 59.
  • the spreading and the equalization of the batch are ensured by a spreader designated as a whole by the reference 60 in FIG. 7.
  • This spreader comprises a frame 61 secured to the arm 58 which carries four axes 62 on which pinions 63 are mounted, at least one of which is driven from the hedgehog axis 57; these sprockets guide two endless chains 64.
  • On said endless chains are mounted regularly spaced axes 65 which carry flaps 66 directed towards the rear and capable of coming into abutment on the rear axis 65.
  • the assembly is surrounded by a casing 67 which surrounds the two vertical strands and the upper strand of the chain, this casing being closed on its vertical face opposite to the hedgehog 57.
  • the endless chains of the spreader device rotate in the direction of the arrow H so that the axis of articulation of the flaps 66 is located in front.
  • the hedgehog 57 projects the fodder which is brought against it by sliding on the platform 44 suitably inclined by extension of the jack 52 and adjustment of the jack 59, above the lower strand of the chains without end 64 in the housing 67. If there is no bed formed on the perforated plate 68 on which the bed L is formed or if the thickness of the bed is small as illustrated in the left part of the figure 7, the flaps 66 hang freely and the projected fodder passes freely between them. When, on the other hand, the fodder bed rises, the flaps 66 gradually rise and brake then stop the passage of the fodder which is retained in bed F above the flaps. Detectors of any known type detect the raising position of all the flaps 66, which corresponds to a bed L formed over the entire width of the drying area 68, and control the advancement of the device.
  • the device of FIG. 6 raised by lengthening the jack 52 and shortening the jack 55 so that it can circulate freely above the beds, is brought to station M where it receives, on the platform 44, a load of fodder corresponding to the quantity spread over an area a '.
  • the device is then brought above the area a ' i , the pick-up 46 being, in the site plan adopted, in front of the device and the spreader device in the rear.
  • the carriage In line with the downstream end of the area a ' i , the carriage is stopped, the spreading device is placed in a position of cooperation with the end of the platform 44 and the fodder is sent by the hedgehog 57 into the spreader 60.
  • the carriage moves rearwards with respect to arrow C (Fig. 5) to spread its load over the entire area a ' 1 .
  • the pick-up 47 is then brought to the right of the edge of the area a ′ 2 on which the partially dried fodder is located.
  • the end of the platform 44 carrying the pick-up is lowered, this lowering being limited by stop rollers 69.
  • the pick-up is then started and the device advances to scan the area at ' 2 and load the forage on this area onto platform 44.
  • the load can be equalized by tilting, using the jacks, the loading platform.
  • the loaded forage is then spread on section a ' 3 as described above for section a' 1 and the completely dry forage in section a ' 4 is loaded on platform 44 and unloaded in S to be evacuated.
  • the device described with reference to Figures 6 and 7 can also be used in the case of a number of drying areas greater than two.
