Definitions

  • the invention refers to a cooling and rinsing device for tools for processing rocks, preferably used in diamond core drilling coring bits for masonry, concrete or rock.
  • a fluid cooling and rinsing agent such as water is conveyed in a closed rinsing circuit with a collecting container 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 by means of cooling and rinsing contains a collecting container and a reservoir, which is connected via a float valve and automatically refills the collecting container.
  • This cooling and flushing device without pump does not form a closed flushing circuit and therefore at least discontinuously requires a filling of cooling and flushing agent.
  • US3782501 includes the cooling and flushing device for a power tool within a sump a float valve, which determines the coolant or lubricant flow in a closed circuit with reservoir, pump and filter for a control circuit and blocks depending on the tool.
  • a cooling and rinsing device for core drill bits used in diamond core drilling machines has a collecting container with a suction pump and a filter connected via a pressure pump in a closed rinsing cycle.
  • the collecting container which must absorb the entire amount of cooling and detergent, can not be arranged in all applications near the tool for larger amounts of cooling and detergent required due to its volume and mass.
  • the object of the invention is the realization of a cooling and flushing device for tools for processing of rock, the collecting container can be arranged close to the tool even with larger required amounts of cooling and detergent.
  • the cooling and rinsing device has a cooling and rinsing agent in a closed collecting container, which is connected via a suction pump for generating a negative pressure to the atmosphere and a closed rinsing circuit from the collecting container by a connected via a pressure pump for generating the rinsing circuit filter for cleaning the Cooling and rinsing agent and by a tool associated with the collecting means for collecting the flowing back of the tool contaminated cooling and detergent with a suction line back to the collection.
  • this rinsing circuit is combined with a supply circuit in which cooling and rinsing agent, mediated by the suction pump connected to the collecting container and formed in the rinsing circuit on the collecting means and the suction line due to the flow resistance to the atmosphere negative pressure for absorbing the cooling and Rinsing agent is sucked from an open reservoir into the sump, when a arranged in the sump float valve is open to control the level.
  • the cooling and rinsing agent of the storage circuit passes together with the cooling and rinsing agent of the rinsing circuit through the pressure pump in the filter and flows through a filter concentrate drain at the bottom of the filter as soiled cooling and detergent back into the reservoir.
  • the inflow from the reservoir outweighs the outflow into the reservoir and thus compensates for missing coolant and rinsing agent in the rinsing cycle.
  • the outflow into the reservoir outweighs the inflow from the reservoir and thus removes excess coolant and detergent from the rinse cycle. Due to the combined storage circuit, the sump can be made very small and thus placed close to the tool, whereby the absorption of the cooling and rinsing agent is improved on the collecting means, or can be used in the same collection larger amounts of cooling and detergent.
  • a tool device to be cooled is integrated between the filter and the tool in the rinsing cycle.
  • the suction pump and the pressure pump are combined by a common drive, which is further advantageously combined with the drive of the tool device.
  • the collecting container is advantageously designed to float on the cooling and rinsing agent of the reservoir, whereby only a very low negative pressure to promote the storage circuit is necessary.
  • the collecting means is designed as a, a core bit coaxially inside radially sealing receiving, one-sided axially open and at the edge axially sealed against a surface torus with a connection for a suction line.
  • water is the cooling and rinsing agent which combines a high heat capacity and cleaning power with biological safety and the greatest possible availability.
  • a cooling and flushing device 1 a cooling and detergent 2 in the form of water in a closed collection container 3, which is connected via a suction pump 4 with an atmosphere 5, and a closed flushing circuit 6 from the collecting container 3 by a via a pressure pump 7, further through a filter 8, further through a tool device 9 in the form of a core drilling, further on parts of a tool 10 in the form of a core bit and further via a tool 10 associated collecting means 11 with a suction line 12 back to the collecting container.
  • the rinsing circuit 6 is combined with a supply circuit 13, in which the cooling and rinsing agent 2 of a large open to the atmosphere 5 reservoir 14 via a arranged in the reservoir 3, controlled by the level, float valve 15 in the reservoir 3, further together with the rinsing cycle 6 through the pressure pump 7 in the filter 8 and a Filterkonz entratabpound respectively valve 16 at the lower end of the filter 8 as a dirty coolant and detergent 2 back into the reservoir 14 passes.
  • the suction pump 4 and the pressure pump 7 are combined with the power tool 9 by a common drive 17.
  • the collecting means 11 as a, a core bit as a tool 10 coaxially inside with radial seals 18 radially sealing receiving, axially open on one side and axially with axial seals 19 axially against a surface to be machined 20 sealing torus with a port 21 for the Suction line 12 executed by which the contaminated with removed material 22 cooling and detergent 2 is discharged.
