Definitions

  • the present invention relates to a tank of the type comprising an enclosure defined by a cylindrical outer enclosure and a movable radial partition mounted sliding in the enclosure and delimiting on either side, in said enclosure, two reservoirs of variable capacities.
  • Such tanks designed in particular to be mounted on vehicles, have been produced by the applicant company in particular for sanitation applications, in particular for discharging waste present in works such as sewers and / or for emptying pits .
  • One of the reservoirs is intended for the recovery of liquid sludge from the structure or the pit being cleaned, the other reservoir constituting a reserve of clean water which can be injected under pressure into the structure or the pit to be cleaned or possibly a compartment intended to also receive sludge.
  • a tank comprising three tanks for transporting different products, and in particular in the sanitation application indicated above, comprising a tank containing clean water, a tank intended for the reception of sludge and a third tank intended to collect water separated from the recovered sludge, for example by decantation for recycling.
  • tanks with three tanks defined by two fixed partitions or a fixed partition and a movable partition inside the enclosure.
  • This solution only partially makes it possible to vary the volumes of the reservoirs as a function of the quantity of products to be transported and in particular does not prevent a reservoir containing a liquid product from being partially filled during transport, which has tendency to unbalance the vehicle transporting the tank as a result of the accelerations undergone by the liquid contained in the partially filled tank.
  • the tank according to the present invention is essentially characterized by the fact that the movable partition is formed by two walls secured by a cylindrical wall, said movable partition constituting in the enclosure a third reservoir of fixed capacity between the two reservoirs of variable capacities.
  • the present invention also relates to a road vehicle essentially characterized in that it comprises, on a platform; a tank as defined above.
  • filtration means produced in the cylindrical wall of the movable partition formed between said cylindrical wall and the outer casing and / or in the exit of the annular space.
  • seals are advantageously provided between the movable partition constituting the third tank and the envelope defining the enclosure of the tank.
  • These may in particular be inflatable rubber seals.
  • the tank according to the invention also comprises, preferably adjustable, positioning and abutment members for the movable partition so as to position the latter according to one of several positions inside the enclosure.
  • means are provided according to the invention for moving the movable partition inside the enclosure, these means being of the type making it possible to apply a pressure difference on either side of the movable partition.
  • These means may for example include a vacuum pump capable of producing a vacuum on one side of the movable partition.
  • the tank comprises a cylindrical casing 1 closed at the ends by bottoms 2 and 3, which can for example be produced in a conventional manner in the form of covers mounted to pivot to allow access to the interior of the tank.
  • a movable partition generally designated by 4 and comprising, in the example illustrated, two radial partitions of convex shape 5 and 6 secured by a cylindrical wall 7 arranged at a distance of the cylindrical wall of the casing 1 of the tank, leaving an annular space 8.
  • the partition 4 is slidably mounted inside the enclosure 1, inflatable seals 9 being provided between the movable partition and the outer enclosure.
  • the two walls 5 and 6 define between them and the cylindrical wall 7 a reservoir of fixed capacity 10.
  • two reservoirs 11 and 12 are produced in the enclosure of the tank, the capacity of which varies according to the position of the movable partition.
  • the stop 13 which can be fixed, and the stop 14 removable, and on the other hand retractable cleats maneuverable from the outside 15, 16 and 17.
  • the movable partition 4 is immobilized by the lugs 15 and 16 which are in the extended position.
  • the partition were to be more to the left in the drawing, it would be positioned and immobilized by the stop 13 and the cleat 15, the cleat 16 can then be retracted.
  • the partition in the example illustrated can also be maintained between the cleats 16 and 17 or between the cleat 17 and the stop 14.
  • Each of the tanks 10, 11 and 12 is of course provided with inlet and outlet sockets for the connection of conduits making it possible to introduce and respectively extract from the corresponding tank the product which is to remain there.
  • this pressure differential is produced by vacuum using a vacuum pump 18 which can be selectively connected at 19 to the volume of the reservoir 11 and at 20 to the volume of the reservoir 12.
  • the vacuum circuit is of the conventional type and includes a distributor 21 in the form of a four-way valve, a silencer 22, a filter 23 and a safety tank 24.
  • a distributor in the form of a four-way valve 25 allows the selective connection of the vacuum circuit to one or other of the volumes of the reservoirs 11 and 12.
  • filtration means (not shown) at the level of the reservoir 10 defined in the movable partition 4.
  • These filtration means can be of any suitable type and mounted on the cylindrical wall 7, in the annular space 8 or in the means for bringing the annular space 8 into communication with the outside.
