  • the present invention relates to the general field of high pressure water supply installations; it concerns in particular the misting installations, that is to say the installations which, from a water source, a motor pump unit and one or more adapted nozzles, allow the spraying of the high pressure water in the form of a mist of very fine droplets.
  • Such misting plants are widely known and used especially in livestock buildings to provide room cooling. They are conventionally constituted of a high pressure pump unit whose inlet pipe is connected to the city water network (arriving at a pressure of the order of 1 to 3 bars). The output pipe of the pump unit supplies one or more ramps of suitable misting nozzles, this generally at a pressure of between 70 and 110 bar, the flow rate of water at each of the nozzles being between 5 and 20 liters / hour. .
  • the breeders very generally need washing equipment, in particular for cleaning and / or disinfecting the buildings during the period of vacuum, by example between two lots of animals.
  • the washing equipment used by the breeders, or by the service companies specialized in this task, are conventional cleaners operating at high pressures of between 150 and 300 bar.
  • the present invention provides an original misting installation, the pump unit of which is provided, at the outlet, with means also allowing the feeding of a washing lance comprising a suitable nozzle provided at the end of a flexible pipe.
  • This type of multifunctional equipment using the same pump set for a "misting" function and for a “washing” function significantly reduces the investment involved in acquiring the two corresponding functionalities.
  • the pump unit has either a single outlet equipped with means for connecting, optionally, to a misting ramp or to a washing lance, ie a plurality of outlets, at least one of which is dedicated to a washing lance and at least one of which is dedicated to a misting ramp.
  • the pump unit is adapted to allow work in operation "misting”, according to a pressure torque P1 / D1 flow, and to allow work in "washing” operation, according to a pressure pair P2 / D2 flow , the pressure P2 in function "washing" being lower than the pressure P1 in function "misting".
  • the pump unit is advantageously adapted to allow work in operation "misting” at high pressure P1 between 70 and 110 bar, this at a flow rate D1 of up to 20 liters / minute, and to allow work in operation "Medium pressure washing” P2, between 20 and 60 bar, at a flow rate D2 of between 20 and 35 liters / minute.
  • the pump unit comprises an output dedicated to the washing lance and at least one outlet dedicated to a misting ramp, the selection of the "washing" or “misting” mode automatically resulting in the implementation of the adapted pressure, feeding this equipment being carried out by manual operations of opening and closing of the valves provided at the corresponding outlets.
  • the pump unit comprises a high pressure pump actuated by an electric motor, which motor is associated with - a frequency converter powered by a power box, and - an electronic control, said electronic control receiving information from a manual control for selecting one of two pressure and / or flow-rate setpoints to slave said frequency converter and supply either the misting ramp (s) or washing.
  • the washing lance is provided with a manually operated strike and the pump unit further comprises means for stopping the electric motor when disabling said striker of the washing lance.
  • These means are preferably in the form of a pressure switch placed downstream of the high pressure pump and shunted electrically in "misting" mode.
  • the installation comprises a dosing pump of treatment product mounted downstream of the high pressure pump, in parallel with a direct supply of water, the passage of water from the source, by said direct supply or by said metering pump, being determined by a manual selection device of the three-way valve type.
  • FIG. 1 The installation of FIG. 1 comprises a pump unit 1 whose inlet pipe 2 is connected to a source of water 3 (in particular the water supplied by the city network) and whose outlet pipe 4 has the possibility of supplying either a washing lance 5 or one or more misting ramps 6.
  • the washing lance 5 is fed through the outlet 7, associated with a manual valve 8.
  • the washing lance 5 comprises, in particular, an appropriate end nozzle 9 and a manually operated strike 10; it is connected to the valve 8 by a flexible pipe 11 of suitable length.
  • the supply of the misting ramps 6 is carried out by outputs 12 each associated with a manual valve 13.
  • the ramp or ramps 6 each consist of a rigid pipe network equipped with a plurality of conventional misting nozzles 14.
  • the pump unit 1 comprises a high pressure pump 15 actuated by an electric motor 16 associated with a frequency converter 17 (not shown in Figure 1).
  • the electric motor 16 is powered by a power box 18 (not shown in FIG. 1) via the frequency converter 17.
  • this frequency converter 17 is controlled by an electronic control unit 19 (not shown in FIG. 1). ) whose role is to automatically regulate the pressure at the outlet pipe 4, according to an adjustable set point and the flow required by the spray system.
  • the pump unit 1 is adapted to supply either the washing lance 5 or the misting ramp (s) 6, according to two different adapted pressure / flow torque and from a two-position manual control ( position "misting" marked 21, or “washing” position marked 22, in Figure 1), sending the corresponding selection information to the electronic control 19.
  • the pump unit 1 has the ability to provide a variable pressure water flow from 0 to 110 bar.
  • this pump unit 1 is set to deliver a first pressure / flow torque adapted to ensure proper operation of the misting ramp (s) 6; in particular, it then makes it possible to work at a water pressure of between 70 and 110 bar (preferably around 100 bar), for example up to 15 liters / minute.
  • the pump unit 1 is set to deliver a second pair of pressure / flow adapted to ensure proper operation of the washing nozzle 9; in particular, it then makes it possible to work at a water pressure of between 40 and 60 bars (preferably around 50 bars), for example up to 27 liters / minute.
  • the corresponding parameterization is performed according to the type of nozzle 9, 14, and as a function of the number of nozzles 14 related to the misting function. It is possible to set a target value to reach, either pressure or flow. In practice, the maximum value of flow rate to be ensured in "misting" mode is determined, then the motor rotation frequency is adjusted by adjusting the setpoint II of the variator. The same is done for the "washing" mode with setpoint 1.
  • the action on the selector 20 causes the implementation of the desired pressure / flow torque; the supply of equipment 5 or 6 that is to be implemented is effected by manually opening and closing, in a suitable manner, the valves 8 and 13 of the outlets 7 and 12.
  • FIGS. 1 and 2 also show the presence of a pressure switch 29 placed downstream of the high-pressure pump 15, able to detect a high threshold and a low pressure threshold and able to send the corresponding information to the electronic control unit. 19. From the detected pressure values, the electronic control 19 is charged, in "washing" mode, to stop the electric motor 16 when the high pressure threshold is reached, and to restart said motorization when the low threshold is reached. achieved. In particular, this feature makes it possible to secure the operation of the lance 5 and the pump unit 1 by stopping the motorization 16 when the keeper 10 of the washing lance 5 is deactivated.
  • the pressure switch 29 is shunted electrically in "misting" mode to allow and not disrupt the implementation of this function.
  • a metering pump 30 connected in parallel with a direct supply pipe 31.
  • the metering pump 30 is a positive displacement pump used to incorporate into the supply water of the high pressure pump 15 a selected dosage of any treatment product useful in "washing" and / or "misting" mode.
  • a disinfectant product for the "misting" mode of a disinfectant product, a disinsectant product, a wetting product, a preventive and / or curative product for animals or a product for the treatment of odors of ammonia, hydrogen sulphide or other components.
  • a cleaning product or detergent it may be a cleaning product or detergent.
  • a pressure-controlled multifunctional high-pressure apparatus is obtained which makes it possible to carry out all the activities related to high-pressure misting (room cooling, odor destruction, disinfection, disinsectisation, curative treatment, soaking, dust abatement, etc.). ) and perform "medium pressure" washing work.
  • This type of multifunction device significantly reduces the hardware investment required to implement all these functions.
  • all these functions can be implemented very quickly, from a simple operation of the selection control 20, the output valves 8, 13 and the three-way valve 32, in association where appropriate with a appropriate choice of the treatment product provided by the metering pump 30.
  • this apparatus allows the implementation of an original procedure for cleaning structures or premises / buildings equipped; indeed, this cleaning may advantageously consist of a prior operation of soaking structures by implementing the installation in function "misting", then, when it is estimated that sufficient soaking, using the washing lance 5 to perform the cleaning well said.
  • the pre-soaking (which advantageously uses a wetting agent delivered by the metering pump 30) makes it possible to substantially facilitate the subsequent cleaning by the lance 5. It allows in particular the use of medium pressure (40 to 60 bar, preferably around 50.degree. bars) with all the inherent advantages in terms of reducing the hardness of work, saving water and reducing the degradation of structures.
  • the pump unit 1 may be provided with a single outlet equipped with means (for example of the quick-connect type) making it possible to connect it either to the misting ramp or to the washing lance. .
