Definitions

  • the invention relates to a mixing device for liquids, in particular for the dilution of cleaning and disinfecting concentrates with water in a defined mixing ratio.
  • the dilution of detergents and disinfectants is done in the prior art with devices that operate on the so-called "Venturi principle". It is a vacuum system that works in proportion to the flow rate. Due to the negative pressure arising behind the venturi nozzle, which theoretically depends solely on the flow rate of the water, the respective amounts of cleaning agent or disinfectant are added to the water. However, the amount of sucked cleaning or disinfecting agent is also dependent on other factors, than only the amount of water flowing through. Among other things, the amount depends on the respective water pressure. Varying water pressures in the pipe system therefore lead to an inaccurate mixing ratio. In addition, water temperature and water hardness have an effect on the amount of concentrate supplied.
  • the invention aims to remedy this situation.
  • the invention has for its object to provide a mixing device for liquids, in particular for the dilution of cleaning and disinfectant concentrates, in which a continuous, accurate mixing ratio is guaranteed.
  • this object is achieved in that the concentrate supply takes place by means of a proportional mixer and a regulating screw is provided with a locking ring for adjusting the mixing ratio.
  • a mixing device for liquids in particular for the dilution of cleaning and disinfectant concentrates is created, which ensures a continuous and accurate mixing ratio.
  • the adjustment screw enables a supply of the cleaning and disinfectant concentrates based on the respective application.
  • the device is independent of water pressure fluctuations, the water temperature or water hardness consistently used exactly. Also, the risk of blockage of the device is significantly reduced.
  • the regulating screw is part of a connecting piece, which comprises a Saugventilfeder, a Saugventildichtung and a connection head for a suction hose.
  • suction hoses are provided for connection of concentrate containers, which have a check valve with a weight.
  • a quick coupling is provided for connecting a water gun to at least one connection hose. This allows a simple connection of a water gun for cleaning or disinfecting large areas.
  • a mixer tap is provided for exact water control. As a result, the adjustment of the temperature of the water inlet is possible.
  • the selected as an embodiment device for dosing of cleaning and disinfecting agents comprises a hot water pipe system 1 and a cold water pipe system 2.
  • the hot water pipe system 1 has in the embodiment two and the cold water pipe system 2 each four branches, each in mixing valves open, in which hot and cold water are mischbar miteinender.
  • the mixing valves 3 are part of a - not shown - mixer for accurate hot water temperature control. A defined maximum permissible water temperature can be set on the mixer tap.
  • the mixing valves 3 are in each case connected to a proportional mixer 4, to each of which a container 5 for receiving cleaning or disinfecting concentrate is connected. From each proportional mixer 4 performs a discharge line 6, which is provided at its free end with a valve 7.
  • the entire device is arranged in the embodiment in a cabinet 8, which consists of stainless steel and is lockable.
  • the hot water pipe system 1 enters the cabinet 8 through an opening 81; the cold water pipe system 2 enters the cabinet 8 through an opening 82. Adjacent to the openings 81 and 82, system dividers 11, 21 are respectively arranged in the piping systems 1 and 2.
  • the system separators 11, 21 are prescribed in devices of the present type, in order to prevent a backflow of cleaning or disinfecting agent into the water pipes from which the hot or cold water is removed.
  • the line systems 1, 2 furthermore have pressure reducers 12, 22, which ensure a uniform pressure in the device and thus form a protection against pressure fluctuations, in particular for the proportional doser 4.
  • the pressure reducer 12, 22 are equipped in the embodiment with a filter on the water inlet side. They can also be equipped with a pressure gauge.
  • the mixing valves 3 are formed in the embodiment as ball valves. They each have two inlets, one of which is intended for hot, the other for cold water.
  • the mixing valves 3 furthermore each have an outlet, from which the mixture resulting from cold and warm water leaves the respective mixing valve 3.
  • the setting of the mixing ratio takes place via an actuating lever 31.
  • the proportional mixer 4 has an inlet for the mixed water of hot and cold water and an inlet for the cleaning and disinfecting concentrate. Furthermore, the proportional mixer 4 is provided with an outlet to which the discharge line 6 is connected.
  • a connecting piece 41 is arranged on the proportional mixer 4, which has a regulating screw with locking ring 411 for continuous adjustment of the desired mixing ratio, which is connected to a suction valve 412.
  • the suction valve 412 is biased by a Saugventilfeder 413 and is sealed via a Saugventildichtung 414 opposite the inlet 415 of the fitting 41.
  • the intake hose 52 can be connected to the connection piece 41 via a connection head 416.
  • the proportional mixer 4 operates in principle like a pump.
  • the water pressure of the mixed water flowing through the proportional mixer 4 acts as a drive for the piston and sucks the concentrate from the containers 5.
  • the mixture of water with the concentrate takes place in an integrated mixing chamber in which the metered solution is homogenized ,
  • the delivery rate of the pump is dependent on the volume flow of the water flowing through the proportional mixer 4.
  • the mixing ratio of the detergent or disinfectant concentrate to the amount of water does not need to be checked and readjusted after a single adjustment.
  • the amount of concentrate remains constant and strictly proportional to the amount of water even in case of pressure or throughput fluctuations.
  • the containers 5 are usually commercially available canisters in which the cleaning and disinfecting concentrates are offered by the manufacturers.
  • the container sizes can be arbitrary, with sizes up to 10 kg predominantly apply.
  • the containers 5 each have an opening 51. Via a suction hose 52, the container 5 are connected to the proportional mixer 4 in connection. It is not necessary to attach the suction hoses 52 to the containers 5; rather, it is sufficient to suspend the suction tubes 52 through the openings 51 of the container 5 in this.
  • the suction hoses 52 have for this purpose at their end a check valve with a weight 53, whereby an inadvertent suction of over the Konzentrat Schillpegel air is avoided. Due to the secure placement of the container 5 in the cabinet 8 there is no risk that the suction hoses 52 are accidentally removed from the containers 5.
  • the discharge line 6 leads from the proportional meter 4 to the bottom of the cabinet 8, in which openings 83 are provided for the exit of the lines 6.
  • the valves 7 are arranged, via which the removal of the metered solution can be shut off.
  • the valves 7 are provided with connections 71 for cleaning hoses.
  • the terminals 71 are designed as a quick coupling.
  • the metered solution can also be filled in a bucket or a watering can.
