Definitions

  • the invention relates to a pressure chamber blasting device consisting of a blasting agent container with a blasting agent insertion opening which can be closed by means of a cone and a blasting nozzle connected to the blasting agent container by means of a blasting hose, the blasting agent container and the blasting hose being connected to a compressed air source via a pressure medium control valve and the closing cone in the pressure medium supply line leading into the container is guided such that it is actuated in the closing direction by the inflowing pressure medium.
  • the pressure chamber blasting devices of this type have proven themselves well in that good blasting results are achieved with their help.
  • the abrasive medium container remains under pressure after the pressure medium control valve is closed and the pressure relief or venting until the air stored in the blast medium container is completely blown off after the control valve designed as a two-way valve is switched off the blasting hose or via the blasting nozzle with the appropriate subsequent blasting of the blasting medium.
  • the aim of the present invention is to provide a pressure chamber jet device of the type described, in which the pressure relief of the container and the pressure medium lines takes place automatically, and the invention is that a two / three-way valve is provided as the pressure medium control valve, which is used by a further two / three-way valve Push button is pneumatically actuated and the pressure medium control valve controls a pressure medium line branching to the blasting medium container and the blasting hose, a water separator being arranged between the pressure medium control valve and the container before the branching, and a check valve being arranged in the branch leading to the blasting hose.
  • the invention provides a pressure chamber blasting device in which, at the same time as the pressure medium flow is blocked, the container is vented by automatically opening the container to the atmosphere via the pressure medium supply line, which now serves as the ventilation line, and the R port of the control valve. This means that the additional vent valve attached to the boiler can be dispensed with; all the required functions are controlled in one valve.
  • pressure chamber blasting device Another significant advantage of the pressure chamber blasting device according to the invention can also be seen in the fact that the pressure is not relieved directly via a valve that opens directly to the atmosphere, but via the closing cone guide located in the dome of the container, through which no or at most negligible small amounts of wear the abrasive that caused it is entrained outside
  • the pressure medium control valve is reversed immediately upon closing the button and thereby pressure relief takes place via the pressure medium line.
  • the water separator downstream of the pressure medium control valve serves as a self-cleaning dust filter in this air flow direction, through which both the pressure medium
  • the control valve and the atmosphere are reliably protected from any type of entrained dust or blasting media and are cleaned by backwashing immediately when the blasting process is resumed by the compressed air flowing back into the container or the blasting hose.
  • the blasting agent located in the blasting hose and entrained with the refluxing air is therefore only returned to the container and held back by the blasting agent column, whereby blasting agent entrained from the blasting agent column or entrained dust particles are essentially retained at the closing cone of the container filling opening. Any particulate matter that is entrained is then filtered out in the water separator.
  • the invention is illustrated, for example, in the schematic representation of a pressure chamber blasting device with an automatically pneumatically controlled control valve drawing.
  • 1 denotes the blasting agent container of a pressure chamber blasting device, which is provided with a blasting agent filling opening 3 which can be closed by means of the closing cone 2 and a blasting nozzle (not shown) connected to the blasting agent container 1 by means of blasting hose 4, the blasting agent container 1 and the blasting hose 4 being provided with a pressure medium control valve a compressed air source are connected and the closing cone 2 is guided in the pressure medium supply line 6 leading into the container such that it is actuated in the closing direction by the inflowing pressure medium.
  • the pressure medium control valve is formed by a two / three-way valve 5, which is actuated pneumatically by means of a two / three-way valve 7 as a button arranged on the blasting nozzle and controls a branching line at 10, from which one branch 6 to the blasting agent container and the other branch 8 leads to the blasting hose.
  • a water separator 9 is arranged between the pressure medium valve 5 and the branch 10, while in the line 8 leading to the blasting hose 4 directly behind the branch 10, i. H.
  • a check valve 12 is arranged at a large distance from the blasting nozzle or the blasting agent inlet 11.
  • the pressure path from the compressor supply line 13 to the Z connection of the pressure medium control valve is released, whereby the pressure chamber jet device is acted upon with compressed air by closing the R connection and opening the pressure medium path from P to A of this valve.
  • the closing cone 2 is raised, thus closing the blasting agent filling opening 3 and consequently building up pressure in the container 1, the check valve 12 is opened at the same time as the pressure builds up, and the pressure medium path is released into the blasting hose, into which the blasting medium comes out of the container 1 is fed into the mouth 11 under the pressure building up there.
  • the separator 9 acts as a water separator, on the sintering insert 9a of which the moisture introduced with the air condenses, which drips into the bottom of the separator and can be removed from time to time via the bottom valve.
  • the P connection of the pressure medium control valve 5 is closed and its R connection is opened towards A, whereby the entire device is opened to the atmosphere.
  • the check valve 12 is first closed, thereby preventing the air from flowing back via the line 8 and, in particular, from the blasting hose 4 flowing back beyond the valve. Rather, the pressure medium and blasting medium return flow takes place completely via the container 1, in which the blasting medium flowing back from the blasting hose 4 is collected. Any abrasive that is entrained from the blasting agent column and entrained dust particles primarily catch on the closing cone 2 and fall back into the container. Residual dust quantities passing into the line 6 are caught in the sintering insert 9a of the water separator 9, which acts as a dust filter in this phase. The valve 5 and the atmosphere are completely protected against dust.
