Definitions

  • the invention relates to a cooling and rinsing device for tools for machining Rock, preferably for core drill bits used in diamond core drilling machines Masonry, concrete or stone.
  • a fluid coolant and flushing agent such as water in a closed flushing circuit with one Collection container conveyed by means of a pump at least over parts of the tool.
  • the cooling and rinsing device for a tool in the form of a Stone saw with a stone saw blade cooled with coolant and washing-up liquid and a storage tank connected via a float valve, which holds the Refills the collection container automatically.
  • This cooling and rinsing device forms without a pump does not have a closed rinsing cycle and therefore needs one at least discontinuously Refill of coolant and detergent.
  • the cooling and rinsing device for a tool device a float valve inside a collecting tank, which is in a closed Circuit with reservoir, pump and filter for a control circuit for the cooling or Lubricant flow determined and depending on it blocked the tool.
  • EP0941828 has a cooling and rinsing device for in diamond core drilling machines used core drill bits a collecting container with a suction pump and one over a pressure pump connected filter in a closed flushing circuit.
  • the Collection container which has to hold the entire amount of coolant and detergent, can with larger amounts of coolant and detergent due to its volume and its mass can not be arranged near the tool in all applications.
  • the object of the invention is to implement a cooling and rinsing device for Tools for processing stone, their collection containers even with larger ones required amounts of coolant and detergent can be arranged close to the tool.
  • the cooling and flushing device has a coolant and flushing agent in a closed one Collection container, which with a suction pump to generate a vacuum is connected to the atmosphere and a closed flushing circuit from the collection container by one connected via a pressure pump to generate the flushing circuit Filters for cleaning the coolant and dishwashing liquid and through one assigned to the tool Collecting agent for collecting the contaminated material flowing back from the tool Coolant and flushing agent with a suction line back to the collection container.
  • this rinsing circuit combines with a supply circuit in which coolant and detergent, mediated by the suction pump connected to the collection container and in the rinsing circuit above the catchment and the suction line due to the flow resistance vacuum developed to absorb the cooling and Detergent is sucked into the collection container from an open storage container when a float valve arranged in the collecting tank for regulating the fill level is open.
  • the coolant and flushing agent in the supply circuit arrive together with the Coolant and flushing agent of the flushing circuit through the pressure pump into the filter and overflows a filter concentrate drain at the bottom of the filter as a dirty cooling and Detergent back into the storage container.
  • the inflow from the reservoir predominates Drain into the reservoir and thus compensates for the lack of coolant and detergent in the Rinsing cycle off.
  • the outflow predominates in the Storage container the inflow from the storage container and thus removes excess Coolant and flushing agent from the flushing circuit. Thanks to the combined supply cycle the collection container is made very small and thus arranged close to the tool be, so that the suction of the coolant and flushing agent through the collecting agent is improved, or larger quantities of cooling and Detergent can be used.
  • a tool device to be cooled between filter and tool in the is advantageous Integrated rinsing circuit.
  • suction pump and the pressure pump are advantageous due to a common drive combined, which is further advantageously combined with the drive of the tool device.
  • the tool device advantageously contains the collecting container and further advantageously the Storage container, with the tool device also advantageously being designed as a core drilling device is.
  • the collecting container is advantageously floatable on the coolant and flushing agent of the storage container executed, whereby only a very low negative pressure to promote the supply cycle necessary is.
  • the collecting means is advantageous as a, a core drill bit coaxially inside radially sealing, axially open on one side and axially against a surface at the edge sealing torus with a connection for a suction line.
  • Water is the coolant and flushing agent, which has a high heat capacity and is advantageous Cleaning power with biological harmlessness and the greatest possible availability combined.
  • a cooling and rinsing device 1 has a coolant and rinsing agent 2 in the form of Water in a closed reservoir 3, which with a suction pump 4 an atmosphere 5 is connected, and a closed flushing circuit 6 from Collection container 3 through a via a pressure pump 7, further through a filter 8 through a tool device 9 in the form of a core drilling device, further over parts of a tool 10 in the form of a core drill bit and further via a tool 10 assigned Collection means 11 with a suction line 12 back to the collecting container 3.
  • the rinsing circuit 6 is combined with a supply circuit 13 in which the coolant and rinsing agent 2 from a large storage container 14 open to the atmosphere 5 via a storage container 3 arranged, controlled by the level, float valve 15 in the collecting container 3, further together with the flushing circuit 6 through the pressure pump 7 into the filter 8 and over a filter concentrate drain or valve 16 at the lower end of the filter 8 as contaminated coolant and flushing agent 2 gets back into the storage container 14.
  • the Suction pump 4 and the pressure pump 7 are connected to the tool device 9 by a combined drive 17 combined.
  • the collecting means 11 as a, a core bit as a tool 10 coaxially in Interior with radial seals 18 radially sealing, axially open on one side and at the edge with axial seals 19 axially sealing against a surface 20 to be machined Torus executed with a connection 21 for the suction line 12, through which the removed material 22 contaminated coolant and detergent 2 is discharged.
