Definitions

  • the invention relates to a method for surface treatment, in particular cleaning of surfaces with CO 2 dry ice granules and a device for performing this method with a dry ice cleaning device for surface treatment with CO 2 dry ice reservoir and at least one high-pressure-resistant hose line with a spray gun at its free end.
  • the object of the invention is to avoid these disadvantages of the prior art, in an economically and structurally simple manner, wherein not only a reduction in dry ice consumption, but also an adapted beam intensity is achieved.
  • the invention lies in a method for surface treatment of the type mentioned, with CO 2 dry ice granules through a dry ice granulate hose using a blasting gun, by generating a negative pressure on the blasting gun, which supplies the carbonic acid (CO 2 ) dry ice granules from a supply Dry ice granulate is sucked into the blasting gun via a dry ice supply line and blasted onto the surface to be treated by means of a separate compressed air line and in which a blasting pressure regulator is used to regulate the impact intensity of the carbon dioxide (CO 2 ) dry ice granulate, the blasting pressure preferably being adjustable from 3 to 20 bar.
  • the jet pressure is regulated by changing the air supply to form compressed air, the supply of the dry ice granules being changed at the same time.
  • the blasting pressure on the blasting gun and the delivery rate of the CO 2 dry ice granulate can also be adjusted by separate but working in a controllable manner dependent on each other.
  • the blasting pressure or the blasting quantity can also be regulated directly on the blasting gun using an electrical potentiometer control or a pneumatic control with a separate line from the device to the Venturi nozzle gun.
  • the invention in a device for carrying out the method according to the invention with a blasting gun arranged at the free end of a supply hose, a CO 2 dry ice filling funnel and a screw conveyor, at its mouth and an air motor operated with compressed air to drive it and a downstream agitator driven by it, the supply hose to the blasting gun having both a compressed air line and a separate line for the supply of CO 2 dry ice granules, which opens at its free end on the blasting gun into a chamber which is pressurized by means of the compressed air line , whose CO 2 dry ice granules sucked into it can be blasted from the blasting gun onto the surface to be treated or cleaned.
  • the amount of CO 2 dry ice can preferably be regulated jointly from the operating handle of the blasting gun by simultaneously driving the air motor and the screw conveyor by means of the compressed air compressor, or the amount of compressed air and the CO 2 dry ice granulate can be regulated separately from the operating handle of the blasting gun using the screw conveyor.
  • solid carbonic acid (CO 2 ) in the form of highly compressed granules is filled as dry ice granules 2 into a double-walled, insulated dry ice filling funnel 1, which forms a supply 3 in the dry ice filling funnel 1 and on a side wall slope 44 under the effect of gravity, optionally with a vibrating or tapping vibration by means of a knocker 10 or tapping on the dry ice filling funnel 1 in adjustable time intervals to ensure even slipping of the dry ice granules 2.
  • the dry ice granules 2 pass through the mouth 9 of the dry ice filling funnel 1 into a screw conveyor 5, which is driven by a pneumatically operated air motor 16, so that the dry ice granules are conveyed through a blasting agent connection 57 into the dry ice granulate hose 6.
  • the air motor 16 simultaneously drives an agitator 4, which protects the CO 2 granules from clumping by means of its stirring movement.
  • the negative pressure generated in a chamber 17 of a blasting gun 11 sucks in the CO 2 granulate and is blasted by the compressed air fed in by a compressor through a nozzle 12 of the blasting gun 11 onto the surface to be treated.
  • a display panel 13 is attached to the front of the device, behind which there is a pneumatic control 45.
  • a delivery pressure regulator 18 allows a variation in the impact intensity of the CO 2 granulate in this area.
  • Another manometer 21 shows the dry ice granulate consumption per hour, which can also be varied by the delivery pressure regulator 22 in a range from 20 kg to 80 kg per hour. This effect is achieved by throttling the air supply to the air motor 16, which is the rotation of the Screw conveyor 5 is affected.
  • the desired aggressiveness of the granular CO 2 pellet jet is achieved by exchangeable air fingers 23-31 and associated jet nozzles or jet pipes 32-40.
  • the individual air fingers 23-31 differ in their air throughput capacity.
  • the operator has the option of changing the jet pressure and delivery rate both on the device and on the blasting gun 11 using two regulators 14-15 or pressure gauges 18 and 19 (FIGS. 4-7).
  • the decisive advantage that this innovation brings is a significantly lower dry ice consumption. Because the operator can regulate the required amount of dry ice and compressed air while blasting the various surfaces. This means that only as much dry ice is blasted as is necessary for the surface to be cleaned.
  • the regulators 14 and 15 can be simple throttles (FIG. 4).
  • the controller 14 or 20 consists of a ball valve 20 which can be actuated by means of the hand screw 21 and with which the air supply can be regulated more uniformly in order to save dry consumption.
  • the controller 15 is connected to the air motor 16 by means of schematically illustrated connecting hoses 15 'in the form of a valve and regulates it pneumatically.
  • the pressure gauge 19 shows the air jet pressure and the pressure gauge 18 shows the delivery pressure of the screw 5.
  • the delivery rate of the air motor 16 can be regulated via a pneumatic switch 46 with an air inlet (47) and outlet 48, specifically by means of a regulator lever 49 which can be pivoted about an axis (50) and which has a spring 51 is biased.
  • the regulator lever 45 is secured at its free end 52 within a long slot 53 of a pawl 54 with limited movement, which can be pivoted about a pivot axis 55 and is held in the securing position within the recess 60 of the pistol grip 59 by means of a tension spring 56.
  • the proportions of the dry ice consumption and the compressed air can be adjusted by different nozzle dimensions of the air fingers 23-31 and the jet nozzles or jet pipes 32-40, which must be adapted to one another in order to optimize the effect of the Venturi suction nozzle 58.
