Definitions

  • the present application is concerned with a device for mixing liquids.
  • the utility model DE 20 205 020 118 U1 shows a sampling device with a cleaning device for a dosing, which is cleaned by means of an ultrasonic actuator.
  • an ultrasonic actuator causes unwanted movements in the fluid, which then splash around.
  • Devices for mixing liquids are shown in DE 102 60 141 A and DE 94 185 38 U1.
  • a device for mixing liquids comprises a vessel having an interior containing an opening at its lower end. The opening can be closed and opened by means of a closure.
  • the apparatus also includes a drain pipe, the interior of which is connected to the opening, and a drain and a first valve for switchably connecting the drain to the drainage pipe.
  • this is not limited to inflexible pipe, it may also be a flexible hose.
  • the apparatus also includes a cleaning fluid reservoir for cleaning fluid and a second valve for switchably connecting the cleaning fluid reservoir to the drainage tube and transport means for transporting cleaning fluid from the cleaning fluid reservoir to the interior.
  • the cleaning fluid reservoir can be designed, for example, as a container or as a supply system for ultrapure water, as is typically provided in clean rooms.
  • the transport means may be a pump which ensures that the cleaning liquid in the first cleaning liquid reservoir is under pressure, so that the cleaning liquid can enter the interior.
  • the device allows the cleaning liquid to be introduced into the vessel not only from above, but also to be passed through the drainage pipe. It may seem unusual at a first glance that cleaning fluid is passed through a drainpipe. However, it has been found that the conventional cleaning with cleaning fluid, for example with ultrapure water only from one side was not sufficient if the highest demands are made on purity. In the conventional cleaning, the flow of the cleaning liquid is only in one direction, so that flushing operations are similar. By contrast, as a result of the fact that cleaning fluid is also conducted through the outflow pipe, a flow is generated whose direction points out of the opening into the interior space. Depositions eg colloids on the walls and edges of the vessel can be better removed.
  • the vessel contains an exterior space for catching liquid overflowing from the interior.
  • the interior can be completely cleaned, that is to say to overflow, by cleaning liquid from the cleaning liquid reservoir.
  • the side walls of the interior can be cleaned and protected up to their upper edge, because if you let the cleaning liquid slowly continue to run, that prevents falling from the top of the container particles pollute the liquid, as they are rinsed out the same.
  • a drainage channel between the outer space and the drain is provided so that liquid, which, coming from inside, overflows, can also run off the same.
  • the device contains a further cleaning liquid reservoir and a liquid dispenser from the further cleaning liquid reservoir, the dispenser being provided above the interior such that liquid from the dispenser falls into the interior.
  • a dosing liquid dispenser in the apparatus serves to dispense liquid to be mixed into the interior of the vessel.
  • an exhaust device and a pump is provided, wherein the exhaust device is connected to the drain pipe and the pump for generating a negative pressure is provided such that liquid particles from the interior into the Extractor be pulled.
  • a drying process can be supported, so that the interior of the vessel is dried before a new dosing.
  • the drain pipe is separated from the interior of the exhaust device when liquid from the drain pipe is not intended to flow inadvertently into the exhaust device.
  • the application also relates to a liquid mixing apparatus comprising:
  • a vessel with an interior for receiving liquids, a first dosing liquid discharge device for injecting liquid to be mixed into the interior, characterized in that the first dosing liquid discharge device has an end which has the shape of a tube and in that the orientation of the tube in an angle greater than 5 degrees to the vertical.

It has been found that in tools where only the tips are made of hard metal and these tips are soldered to the rest of the tool, the solder joints contaminate the components to be manufactured.
