Definitions

  • the present invention generally relates to cleaning devices which, intended to intervene between the inlet and outlet pipes serving water any installation to clean, implement, for the cleaning thereof, a load cleaning body to circulate in this installation.
  • the cleaning bodies used are of relatively small dimensions, of the order for example of 1 or 2 mm, and present in practice in the form of beads or granules.
  • the inlet filter and the outlet cleaning body manifold are rotatable which makes them subject to wear and therefore to maintenance.
  • the exit manifold filter by its rotation and the shear between cartridge and shutter resulting, damages a number of cleaning bodies at each cycle, which gradually reduces the cleaning efficiency and reduces the life of every load of body cleaners.
  • This system comprises to date, in all cases, at least one valve installed on the pipe connecting the storage lock of the cleaning bodies to the injection venturi of said body at the output of the input filter. This open valve at each injection phase and closed during the collection phase intercepts the water loaded with cleaning bodies.
  • the present invention generally relates to a cleaning device free from all or part of these disadvantages.
  • the invention makes it possible to separate the filtration functions from the debris and the recovery of the cleaning bodies.
  • the corresponding filtering devices can therefore be specifically adapted to their function, it being understood that, arranged upstream of the separation means, the filtration means must satisfy a finer filtration setting or, in other words, have a lower mesh. to that of the means of separation.
  • the filtration function is thus mainly provided by the filtration means and the separation means are provided to retain the cleaning bodies. Since the mesh of the separation means is greater than that of the filtration means, the pressure drop generated by the passage of the fluid through the separation means is lower than before.
  • controlled valves which allow the circulation and the stopping of fluid in one and the other of the recovery and reinjection circuits are positioned in parts of the circuits which do not carry cleaning bodies.
  • a controlled valve is not a valve that is operated manually. This is for example a valve whose actuation is controlled by a motor.
  • the filtering member comprises an inlet and an outlet and is surrounded by a body, the inlet being connected to an upstream recovery pipe through which the cleaning bodies are transported to the filtering member prior to to be collected by the latter, the outlet being connected to a downstream line for reinjection of the cleaning bodies into the inlet pipe, two pipes respectively provided with two controlled valves V2, V3 being respectively connected to the body upstream and downstream of the it to bring fluid and evacuate according to the actuation of the controlled valves.
  • the recovery circuit comprises the recovery line, the filtration unit and the pipe provided with the valve V3, while the reinjection circuit comprises the pipe provided with the valve V2, the filtering member and the reinjection line.
  • the recovery circuit of the cleaning bodies is mounted in shunt with respect to the discharge pipe so that the filter member stops the cleaning bodies circulating in the pipe and lets the fluid pass through the pipe. downstream part of the circuit to bring it back into the discharge pipe when the valve V2 is actuated in the closed position and the valve V3 is actuated in the open position.
  • the reinjection circuit of the cleaning bodies is mounted in shunt with respect to the inlet pipe in order to bring, at the level of the body, the fluid taken from the pipe, to make it penetrate into the filtration for driving the cleaning bodies in the downstream part of the reinjection circuit and to the inlet pipe when the valve V2 is actuated in the open position and the valve V3 is actuated in the closed position.
  • the reinjection circuit thus makes it possible, by drawing water from the inlet pipe, to create a circulation of fluid which will entrain the cleaning bodies which have been collected in the filtration unit downstream of the circuit in question. to reinject them into the incoming pipe.
  • the separation means further comprise another filter member placed upstream of the filter member, on the discharge pipe, in order to stop the cleaning bodies and let the fluid pass in the pipe .
  • This other filtering member makes it possible to stop the cleaning bodies and let the fluid flow through the filtering member in order to be discharged from the system.
  • the cleaning bodies are stopped and the fluid flows through said member to join the downstream portion of the recovery circuit and to be introduced into the discharge line downstream of the two bodies of filtration.
  • each of the recovery and reinjection circuits of the cleaning bodies comprises means for creating a suction in the circuit concerned so as to allow the circulation of the fluid.
  • these means comprise a venturi, which makes it possible to obtain a very reduced pressure drop.
  • these means comprise a diaphragm which has the advantage of being less expensive than the venturi.
  • the filtering member is a multicart filter comprising, at the inlet, a fluid flow distribution part which comprises a plurality of flow distribution channels communicating with each other. each with a filter cartridge, the whole of the distribution piece and filter cartridges substantially parallel to each other being arranged in a generally elongated form.
  • This structure is, for example, that of the filtering member common to the two circuits and, optionally, that of the other filtering member of the separation means which is arranged, upstream of the common member, on the circuit of recovery.
  • channels formed in the room are, for example, inclined relative to the longitudinal direction of the filter. They will flare out from the inlet face of the plate to the exit face in order to connect to an upstream pipe of diameter less than the transverse dimension of all the filter cartridges.
  • These filter cartridges may be in practice in a generally cylindrical form and all of these cartridges are, for example, advantageously arranged elongated in a longitudinal direction corresponding to the direction of flow of the fluid.
  • the filter cartridges of the above-mentioned multicartar member are each held in position at their respective two opposite ends.
  • the separation means according to the invention advantageously comprise, excluding valves, whose intervention is only momentary, no mobile mechanical member.
  • no valve intervening in the Normal operation is installed on the lines where the fluid loaded with cleaning substances passes through.
  • the cleaning bodies passing through these pipes are therefore less degraded than before, which reduces maintenance operations and is less expensive.

  • the filtration means 16 comprise a filtering apparatus 19 comprising, in a generally cylindrical body 20, a filtering wall 21 which is also generally cylindrical and fixed. Cleaning the filter body 21 is effected by opening a valve 26 mounted on a pipe 27 connected to the downstream end of the filter body 21 and leading the washing water leaving the filter body 21 to the outlet pipe 12.
  • the driving force creating the flow is constituted by the pressure drop of the circuit between the inlet of the filter 16 and the downstream of the separator 17.
