Definitions

  • the object of the invention is a cleaning device for mechanically manufactured products using a modular drive of individual cleaning chambers separated from each other, the drives and cleaning nozzles being controlled so that each chamber module performs a certain degree of cleaning of the products.
  • the cleaning water of the individual chambers does not flow freely back and forth between the chambers, but is controlled according to the degree of contamination.
  • Such a modular cleaning system is useful wherever metallic and non-metallic materials are processed to remove impurities in the form of chips, shavings, burrs, emulsions, dust and other contaminants.
  • the present invention proposes a treatment plant for purifying indoor flue gases which, in addition to cleaning, also provides humidification and temperature control of the indoor air.
  • This patent has no technical features in common with the proposed invention.
  • None of these inventions proposes pumping contaminated water between chambers.
  • the present invention relates to a process for the treatment of industrial wastewater with a low content of toxic organic substances, in particular highly toxic, non-biodegradable organic substances, using catalytic oxidation.
  • Some of the machines - treatment plants use the same water through all the tunnel chambers.
  • Machines with multiple pools usually use multiple water systems in different chambers.
  • the dirty water from the first chamber - with cleaner agent - moves strongly gradually and along the conveyor chain, belt, etc. towards the second chamber.
  • the maintenance cycle is extended and the cleaning quality is improved.
  • Computer-controlled servo drives ensure that the items that are being washed can be cleaned in a targeted manner (in case of jammed chips, etc.).
  • the problem with the existing systems is that they also use a lot more treatment water because we have to use fresh, unpolluted water at the end of the sewerage system, which means that the cost of treatment is high and the pollution of the environment or the discharges into the sewerage system are high.
  • Another problem with existing systems is that the journey through the cleaning tunnel is just one and the products cannot be treated partially depending on the level of contamination (in each separate chamber), but are treated continuously along the entire treatment route.
  • washing in existing systems is random and a lot of energy is wasted in this random manner (random water spraying, random positioning of the items, no closing of the chambers).
  • the objects to be cleaned are of different shapes and must be rotated according to the direction of the cleaning water of the cleaning nozzles for complete cleaning, which is not possible with the existing systems, so that the required degree of cleanliness of the objects cannot be achieved.
  • the pallet is moved up and down the chamber as desired, depending on the shape and dirtiness of the objects, to achieve optimal cleaning. It allows pallet and its items to stop and to even reach inside of different parts with moving rods connecting to air or servo driven cylinders.
  • a module or chamber is usually 2 times as long as the pallet or object carrier.
  • CNC program is set - programmed with classic G and M codes.
  • the nozzles can be mounted on the cylinders and perfectly positioned on the air cylinders near the dirty zone of each object.
  • the proposed invention allows a much better, faster and higher quality cleaning of objects, since the objects are cleaned step by step in each chamber according to a predetermined program which allows reversing the driving direction of the carrier on which the objects are placed according to a certain geometry, or positioning the objects under the cleaning nozzles in such a way that these nozzles clean the intended surfaces of the objects.
  • the first chamber cleans most of the contaminants
  • the next chamber again uses its unique single program to clean the remaining contaminants and so on until the last chamber again rinses the objects according to its program intended for a specific range of objects.
  • the objects are loaded onto the carrier (pallet etc.), usually by a robot or a manipulator, according to a specific program that we have established according to the results of the washing tests for the different objects.
  • the individual chamber recognises - reads - a specific carrier via a CNC program, via a barcode, RFS signal, mechanically or otherwise, which is not the object of the present invention, and triggers the individual program of the respective chamber intended for cleaning the objects held on the carrier according to a partial standard cleaning protocol entered in the computer program of the entire system.
  • a partial standard cleaning protocol entered in the computer program of the entire system.
  • the cleaning waters or cleaning agents from the individual chambers do not mix uncontrollably with each other and the cleaning rate is therefore much higher, as the last chamber has the cleanest water intended only for rinsing the objects.
  • the clean water is used and periodically flows to the prior chamber, where the cleaning agent is automatically added.
  • This water or cleaning agent from the last chamber which is occasionally partially replaced by fresh water, can be dosed into the previous chambers via a controlled system, which is the case with all interconnected chambers.
  • This water is also treated and returned to the process or the last chamber through special treatment systems, which are not the subject of this application.
  • the final chamber may be a blow-off chamber in which air is injected under pressure through nozzles onto the objects, thereby drying the objects.

  • the last chamber K can also be a so-called vacuum chamber K, in which water vapour and water or cleaning agent OV are extracted from the objects P or from the chamber K via the spray nozzles BS.

  • the mutual control of the chambers K is not the subject of the present application, since it relies on known prior art. However, it is of the utmost importance that the following conditions are met when moving the carrier N from the preceding chamber K to the succeeding chamber K, namely: a.
