Description
L'invention se rapport à une épandeuse de produits salins de déverglaçage pour le traitement par arrosage de chaussées et de surfaces analogues, comprenant, sur une plate-forme mobile, une citerne destinée à recevoir le produit à épandre et une barre d'arrosage reliée via une pompe i ladite citerne. The invention relates to a spreader of saline de-icing products for the treatment by spraying of roadways and similar surfaces, comprising, on a mobile platform, a tank intended to receive the product to be spread and a connected sprinkler bar via a pump to said tank.
Une telle épandeuse est, selon la présente invention, munie de moyens aptes à réaliser dans la citerne un produit à épandre composé d'une saumure mélangée de fines particules salines. According to the present invention, such a spreader is provided with means capable of producing in the tank a product to be spread comprising a brine mixed with fine salt particles.
On sait qu'un produit de déverglaçage ainsi composé est particulièrement efficace pour le traitement hivernal des chaussées et voies diverses, notamment en raison du fait que l'eau libérée par fusion de la neige ou de la glace sous l'action de la saumure dissout au fur et à mesure le sel accompagnant celle-ci sous forme de fines particules, ce qui évite la dilution de la saumure et maintient sa concentration, donc son activité de déverglaçage. It is known that a de-icing product thus composed is particularly effective for the winter treatment of roads and various routes, in particular due to the fact that the water released by melting of snow or ice under the action of dissolved brine gradually the salt accompanying it in the form of fine particles, which avoids dilution of the brine and maintains its concentration, therefore its de-icing activity.
Dans une forme d'exécution préréri d'une épandeuse selon l'invention, la citerne comporte, disposé dans sa partie supérieure et ouvert vers l'extérieur, un panier perforé à l'intérieur duquel débouche un tuyau relié à la sortie de la pompe et susceptible, après remplissage partiel de la citerne avec une saumure, d'assurer la dissolution d'un sel introduit sous forme solide dans le panier perforé par déversement sur ce sel de saumure prélevée dans la citerne et de faire corrélativement apparattre dans la citerne un précipité du sel constitutif de la saumure imi1ialement introduite dans celle-ci. In a preferred embodiment of a spreader according to the invention, the tank comprises, arranged in its upper part and open towards the outside, a perforated basket inside which opens a pipe connected to the outlet of the pump. and likely, after partial filling of the tank with brine, to ensure the dissolution of a salt introduced in solid form into the perforated basket by pouring on this brine salt taken from the tank and to correlatively appear in the tank a precipitate of the constituent salt of the brine originally introduced therein.
C'est ce précipité qui apport dans la saumure les fines particules salines précitées.It is this precipitate which brings the aforementioned fine salt particles into the brine.
De préférence, sur le tuyau débouchant dans le panier perforé est montée une vanne, qui permet d'interrompre le déversement de saumure dans le panier perforé en dehors des périodes de dissolution du sel introduit sous forme solide. Preferably, on the pipe opening into the perforated basket is mounted a valve, which makes it possible to interrupt the discharge of brine into the perforated basket outside the periods of dissolution of the salt introduced in solid form.
La citerne peut avantageusement comporter, dans Sa partie inférieure, une rampe reliée à la sortie de la pompe et munie de buses émettant des jets qui assurent le brassage du contenu de la citerne et la mise en suspension de manière homogène des particules du précipité an sein de la saumure. Il convient d'interposer entre cette rampe et la pompe un clacet taré à limitation de pression de de manière que l'alimentation/la rampe assure en meme temps le maintien à une valeur constante de la pression appliquée à la barre d'arrosage,avec renvoi de l'excédent de saumure dans la citerne. The tank may advantageously comprise, in its lower part, a ramp connected to the outlet of the pump and provided with nozzles emitting jets which ensure the mixing of the contents of the tank and the homogeneous suspension of the particles of the precipitate within brine. It is advisable to interpose between this ramp and the pump a calibrated valve with pressure limitation so that the supply / the ramp ensures at the same time the maintenance at a constant value of the pressure applied to the sprinkler bar, with return of excess brine to the tank.
De préférence, la saumure initialement introduite dans la citerne est une solution saturée de chlorure de sodium, tandis que ,en ce qui concerne le sel ajouté pour dissolution dans le panier perforé, on peut
choisir le chlorure de calcium.Preferably, the brine initially introduced into the tank is a saturated solution of sodium chloride, while, as regards the salt added for dissolution in the perforated basket, it is possible to
choose calcium chloride.
Une épandeuse selon l'invention, capable d'assurer la préparation et l'6pandage du produit de salage mixte précité àhaut pouvoir déverglaçant, est surtout destinée au traitement des chaussées dans les cas difficies, à titre curatif (neige tassée, verglas déjà formé) ou à titre préventif ou semi-préventif (pluie verglaçante, pluie en surfusion). Elle peut évidemment aussi être utilise pourl'épandage de saumures simples, sans particules solides. A spreader according to the invention, capable of ensuring the preparation and spreading of the aforementioned mixed salting product with high de-icing power, is especially intended for the treatment of pavements in difficult cases, for curative purposes (packed snow, ice already formed) or as a preventive or semi-preventive measure (freezing rain, supercooled rain). It can obviously also be used for spreading simple brines, without solid particles.
Par ailleurs, elle peut être conçw selon le brevet n 76/01 856 pour effectuer l'épandage avec un débit dépendant de la vitesse de progression, et eile peut recevoir au surplus un équipement pour l'épandage de produits solides conformément aux certificats d'addition n 76/28 285 et n 79/14 169.Furthermore, it can be designed according to patent n 76/01 856 to carry out spreading with a flow rate dependent on the speed of progression, and it can also receive equipment for spreading solid products in accordance with the certificates of addition no 76/28 285 and no 79/14 169.
La description qui va suivre, en regard du dessin annexé à titre d'exemple non limitatif , permettra de bien comprendre comment la présente invention peut autre mise en pudique. The description which follows, with reference to the attached drawing by way of non-limiting example, will make it possible to understand clearly how the present invention can be put in a different mood.
La figure unique représente schématiquement une épandeuse selon l'invention. The single figure schematically represents a spreader according to the invention.
L'épandeuse représentée est un camion comprenant une cabine de conduite 1 et une plate-forme 2 qui supportE une citerne 3 destinée à contenir le produit à épandre. Une pompe 4 est prévue pour soutirer ce produit à la base de la citerne 3, via une conduite 5 munie d'une crépine 6, et ltenvoyer, via une conduite 7 munie d'une vanne 8, à une barre d'arrosage 9. Une conduite de retour relie la sortie de la pompe 4 à une rampe 10 équipée de buses 11 et disposée dans la citerne 3, à la partie inférieure de celle-ci. Sur cette conduite de retour est interposé, outre une vanne 12, un dispositif 13 à clapet de limitation de pression, taré à la pression désirée pour l'alimentation de la rampe 9. The spreader shown is a truck comprising a driving cab 1 and a platform 2 which supports a tank 3 intended to contain the product to be spread. A pump 4 is provided to withdraw this product at the base of the tank 3, via a pipe 5 provided with a strainer 6, and send it, via a pipe 7 provided with a valve 8, to a watering bar 9. A return line connects the outlet of the pump 4 to a ramp 10 fitted with nozzles 11 and arranged in the tank 3, at the bottom of the latter. On this return pipe is interposed, in addition to a valve 12, a device 13 with a pressure limiting valve, calibrated at the desired pressure for supplying the ramp 9.
La sortie de la pompe 4 est églement reliée à une conduite 14, via une vanne 15, aboutissant dans un panier perforé 16 ouvert par le haut et encastré dans la paroi supérieure de la citerne 3. L'extrémité correspondante de la conduite 14 porte des buses de sortie 17 par où se déverse dans le panier 16 la saumure envoyée par le pompe 4. The outlet of the pump 4 is also connected to a pipe 14, via a valve 15, ending in a perforated basket 16 open from above and embedded in the upper wall of the tank 3. The corresponding end of the pipe 14 carries outlet nozzles 17 through which the brine sent by the pump 4 flows into the basket 16.
L'épandeuse donnée en exemple peut s'utiliser de la manière décrite ci-après. The example spreader can be used as described below.
Après avoir rempli partiellement la citerne 3 d'une saumure de chlorure de sodium, on introduit dans le panier perforé 16,progressivement ou par doses successives, une certaine quantité de chlorure de calcium en paillettes. La vanne 8 étant fermée et la vanne 15 ouverte , la pompe 4 envoie, via la conduite 14 et ses buses de sortie 17,des jets de saumure sur le chlorure de calcium contenu dans le panier 16, qui en causent la dissolution. Il en résulte que la saumure de la citerne 3 s'enrichit n chlorure de calcium et qu'y apparatt bientôt un précipité du chlorure de sodium qu'elle renferme en solution. Finalement, la citerne contient une mixture formée d'une saumure, très concentrée, de chlorure de sodium et de chlorure de calcium, mélangée de fins cristaux de chlorure de sodium précipité. C'est cette mixture, brossée et homogénéisée par l'action des jets ascendants émis par les buses 11 de la rampe 10, qui sera épandue par ouverture de la vanne 8 après fermeture de la vanne 15. After partially filling the tank 3 with sodium chloride brine, a certain quantity of calcium chloride in flakes is introduced into the perforated basket 16, gradually or in successive doses. The valve 8 being closed and the valve 15 open, the pump 4 sends, via the line 14 and its outlet nozzles 17, jets of brine on the calcium chloride contained in the basket 16, which cause its dissolution. As a result, the brine in tank 3 is enriched with calcium chloride and a precipitate of sodium chloride soon appears in it, which it contains in solution. Finally, the tank contains a mixture of very concentrated brine, sodium chloride and calcium chloride, mixed with fine crystals of precipitated sodium chloride. It is this mixture, brushed and homogenized by the action of the ascending jets emitted by the nozzles 11 of the boom 10, which will be spread by opening the valve 8 after closing the valve 15.
A titre indicatif, on peut remplir initialement la citerne 3 auKdeux tiers de sa capacité avec 5500 litres de saumure à 26% de chlorure de sodium, puis y introduire environ 3 tonnes de chlorure de calcium en paillettes, ce qui conduit à un mélange composé environ de 7200 litres de saumure à 40 et de 1 tonne de chlorure de sodium précipité. As a guide, you can initially fill the tank 3 to two thirds of its capacity with 5500 liters of brine containing 26% sodium chloride, then introduce approximately 3 tonnes of calcium chloride in flakes, which leads to a compound mixture of approximately from 7200 liters of brine to 40 and 1 ton of precipitated sodium chloride.
