Description
L'invention se rapporte à une installation pour la préparation de saumure de sel. The invention relates to an installation for the preparation of salt brine.
Pour, en période hivernale, traiter préventivement ou crativement les routes contre la formation de plaques de verglas et/ou l'accumulation de neige, il est connu de répandre sur ces routes de la saumure de sel pour la préparation de laquelle les services d'entretien de routes ne disposent généralement que de moyens archaïques incompatibles avec l'importance de la demande et qui, par ailleurs, ne garantissent pas l'obtention d'une concentration en sel suffisante pour produire un effet durable. For, in winter, preventively or critically treat the roads against the formation of ice patches and / or the accumulation of snow, it is known to spread on these roads salt brine for the preparation of which the services of Road maintenance generally only has archaic means incompatible with the size of the demand and which, moreover, do not guarantee the obtaining of a sufficient salt concentration to produce a lasting effect.
Un résultat que l'invention vise à obtenir est une installation automatique de production de saumure en quantité importante et avec une concentration suffisante. A result which the invention aims to obtain is an automatic installation for producing brine in a large quantity and with a sufficient concentration.
A cet effet, elle a pour objet une -installation du type précité notamment caractérisée en ce qu'elle comprend
- une cuve dépourvue de couvercle, au fond de laquelle est logée une rampe par laquelle un courant ascendant d'eau est injecté sous pression dans la masse de sel placée dans la dite cuve,
- un réservoir clos,
- une tubulure de trop-plein raccordée en partie haute de la cuve et qui transfert le dit trop-plein dans le réservoir clos,
- une conduite alimentant la dite rampe au travers d'une vanne régulatrice du débit d'eau afin de garantir un certain temps de passage de l'eau dans la cuve avant qu'elle ne gagne le trop-plein,
- piquée à la base du réservoir clos, une conduite de prélèvement de la saumure présente dans ce réservoir.To this end, it relates to an installation of the aforementioned type, in particular characterized in that it comprises
- a tank without a cover, at the bottom of which is housed a ramp by which an ascending stream of water is injected under pressure into the mass of salt placed in said tank,
- a closed tank,
- an overflow pipe connected in the upper part of the tank and which transfers the said overflow into the closed tank,
a pipe supplying said ramp through a valve regulating the water flow in order to guarantee a certain time for the passage of water in the tank before it gains overflow,
- tapped at the base of the closed tank, a brine sampling line present in this tank.
L'invention sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé, qui représente le schéma de l'installation. The invention will be better understood with the aid of the description given below, by way of nonlimiting example, with regard to the attached drawing, which represents the diagram of the installation.
En se reportant au dessin, on voit que l'installation comprend principalement une cuve 1 dépourvue de couvercle et servant à la préparation de la saumure par un courant ascendant d'eau 2 injecté sous pression dans la masse de sel 3 placée dans la dite cuve. Referring to the drawing, it can be seen that the installation mainly comprises a tank 1 devoid of a cover and used for the preparation of brine by an ascending stream of water 2 injected under pressure into the mass of salt 3 placed in said tank .
Cette eau 2 est injectée dans le sel grâce à une rampe 4 logée au fond de la cuve et reliée à une arrivée d'eau 5 sur laquelle peuvent être intercalées une vanne d'isolation 6, une vanne régulatrice du débit 7 et une électrovanne 8 commandant la réalimentation de la cuve 1. This water 2 is injected into the salt through a ramp 4 housed at the bottom of the tank and connected to a water inlet 5 on which an isolation valve 6, a flow control valve 7 and a solenoid valve 8 can be inserted. controlling the tank refill 1.
En partie haute de la cuve est raccordée une tubulure 9 de trop-plein qui transfert la saumure 10 dans un réservoir clos 11 dans lequel la dite saumure est stockée en attendant d'être prélevée par une conduite 12 raccordée à sa base. In the upper part of the tank is connected a tube 9 of overflow which transfers the brine 10 into a closed tank 11 in which said brine is stored while waiting to be withdrawn by a pipe 12 connected to its base.
Cette conduite 12 peut être raccordée à l'épandeuse (non représentée) par un tuyau souple (non représenté). This line 12 can be connected to the spreader (not shown) by a flexible pipe (not shown).
La vanne régulatrice du débit 7, placée à l'entrée de la cuve- 1, est réglée de manière que l'eau mette un certain temps et par exemple quarante cinq minutes pour traverser le sel et parvenir à la tubulure de transfert (9), ce qui garantit une certaine concentration de la saumure. The flow regulating valve 7, placed at the inlet of the tank 1, is adjusted so that the water takes a certain time and for example forty five minutes to pass through the salt and reach the transfer tubing (9) , which guarantees a certain concentration of the brine.
Dans le réservoir clos 11, à sa partie supérieure, est prévu un lecteur 13 du niveau de saumure présente dans le réservoir clos 11, lequel lecteur 13 est relié à un dispositif 14 de pilotage de l'électrovanne 8 précitée pour interrompre l'arrivée d'eau dès que le niveau de saumure est suffisant et pour, au contraire, commander un nouveau cycle de fabrication dès que ce niveau est jugé insufissant. In the closed tank 11, at its upper part, there is provided a reader 13 for the brine level present in the closed tank 11, which reader 13 is connected to a device 14 for controlling the above-mentioned solenoid valve 8 to interrupt the arrival of water as soon as the brine level is sufficient and to, on the contrary, order a new production cycle as soon as this level is deemed insufficient.
La conduite 12 de prélèvement de la saumure présente dans le réservoir clos 11, porte une vanne d'arrêt 15, une vanne régulatrice du débit 16 et une pompe-17. The brine sampling line 12 present in the closed tank 11 carries a stop valve 15, a flow control valve 16 and a pump-17.
Pour le cas où, après contrôle, la concentration de la saumure présente dans la cuve s'avèrerait insuffisante, en sortie de la pompe 17 de prélèvement de la saumure, est raccordée une extrémité 18 d'une conduite de recyclage 19 dont l'autre extrémité 20 est raccordée à l'entrée de la cuve 1 et permet de faire repasser la saumure à travers le sel 3 et d'augmenter ainsi la concentration. In the case where, after control, the concentration of brine present in the tank proves to be insufficient, at the outlet of the brine sampling pump 17, one end 18 of a recycling pipe 19 is connected, the other of which end 20 is connected to the inlet of the tank 1 and makes it possible to iron the brine through the salt 3 and thus to increase the concentration.
Cette concentration pourra se contrôler périodiquement par prélèvement et analyse d'échantillons par la conduite 21 prévue à cet effet. This concentration can be checked periodically by taking and analyzing samples via line 21 provided for this purpose.
Une des causes de l'insuffisance de concentration étant le manque de sel dans la cuve, sur la masse de sel est appuyé un élément 22 relié par un cable 23 passé sur une poulie de renvoi 24 avant de recevoir un contre-poids 25 donnant une information sur la hauteur du sel présent dans la cuve et commande éventuellement l'arrêt de l'arrivée d'eau et/ou un avertisseur et/ou la réalimentation en sel. One of the causes of insufficient concentration being the lack of salt in the tank, on the mass of salt is supported an element 22 connected by a cable 23 passed over a return pulley 24 before receiving a counterweight 25 giving a information on the height of the salt present in the tank and optionally controls the stopping of the water supply and / or an alarm and / or the salt refilling.
Sur la conduite de recyclage 19 sera avantageusement prévu un clapet anti-retour 26 n'autorisant la circulation que dans le sens du recyclage. On the recycling line 19, a non-return valve 26 will advantageously be provided, authorizing circulation only in the direction of recycling.
