Definitions
- the invention relates to a suction and discharge device for a rinsing liquid according to the Preamble of claim 1.
- Flushing liquids are used for the machining of Rock, concrete, masonry or similar materials to cool a tool and that remove drilling cuttings removed from the tool from the machining point.
- a suction and discharge device from EP-0 776 627 known, which has two closed containers, with a smaller container in a larger container is arranged. The larger container works with one device to create a vacuum together. With the help of this vacuum leaves put himself with cuttings. Flush liquid through a suction device the second Feed the container. In the second container there is clean rinsing liquid by means of a device for generating an overpressure and a discharge device can be fed to a processing point. Because the two containers have a limited size have, is the ongoing filling of the smaller one during the machining process Container and emptying the larger container necessary. These measures work not only disadvantageous in terms of time expenditure but also in terms of handling out.
- US 5,601,659 A is a cleaning water treatment system with a suction and Discharge device and a high pressure cyclone sprayer for cleaning large, flat ones Concrete or asphalt surfaces are known, the suction and discharge device having several containers comprises, which are connected to one another via lines.
- the first as a recovery tank trained container acts with a device for generating a negative pressure as well as with a suction device and has several hydrocarbon absorbent Filter bags, which are arranged in several cascade chambers.
- a first device for generating an overpressure is connected to the first container provided in the connecting line, which the pretreated cleaning water pumps into a first and then into a second settling tank.
- the suction and discharge device comprises several individual components and is for transport between the different Application locations arranged on a two-axle trailer.
- the invention has for its object a suction and discharge device for a rinsing liquid to create that related to the whole editing process brings time advantages and is also easy to use.
- the device according to the invention thus acts as a preparation device for the rinsing liquid by using the first container to deposit the cuttings and the second container thanks the line connecting the containers is continuously supplied with rinsing liquid, which via the discharge device is fed to the processing point. An ongoing filling and There is no need to empty the container.
- the device for generating the positive pressure To a certain flow rate of the rinsing liquid within the To be able to reach the container connecting line is in the container connecting line arranged the device for generating the positive pressure.
- the device for generating the positive pressure creates a negative pressure in that Section of the line which is arranged in the flow direction in front of this device.
- rinsing liquid is sucked out of the first container and the Device for generating the excess pressure supplied. So when sucking in Rinsing liquid from the first container does not remove the cuttings that have accumulated on the bottom can get into the second container, is advantageously in the direction of flow the device for generating the excess pressure lying part of the line as from one Bottom of the first container spaced riser formed.
- a particularly good filter effect is achieved if preferably the largest Extent of the pores of the filter element is 0.1 ⁇ m to 10 ⁇ m.
- any Drill cuttings mainly only on the outer contour of the filter element takes preferably the size of the pores in the direction of flow.
- the filter element is expediently made of ceramic educated.
- a very good suction power is achieved in that the device is advantageous generates a pressure of -0.1 to -1 bar to generate the negative pressure.
- the device for generating an overpressure advantageously generates a pressure from 1 to 5 bar. With this pressure, the rinsing liquid can flow well from the first to the second Container and from this through the filter element into the discharge device reach.
- the invention is based on a drawing in which a suction and discharge device for a Rinsing liquid is shown schematically, explained in more detail.
- the device has two containers 1, 2, each of which is closed with a lid 11, 21.
- the first container 1 is equipped with a device 6 for generating a negative pressure Connection that creates a negative pressure in the first container 1.
- This Vacuum is mixed with drilling fluid rinsing liquid, for example in the Drilling holes in hard surfaces such as concrete, stone, masonry or The like occurs via a suction device 3 in the area of a processing point sucked in and fed to the first container 1.
- a suction device 3 in the area of a processing point sucked in and fed to the first container 1.
- the first container 1 that can Separate the cuttings from the dirty rinsing liquid by gravity and on Collect the bottom 12 of the first container 1.
- the flushing liquid which may still contain drilling dust, is passed through one of the two Container 1, 2 connecting line 5 and a device arranged in line 5 7 for generating an overpressure in the second container 2. So that the bottom 12th cuttings from the first container 1 cannot get into the second container 2, is the part of the line 5 projecting into the first container 1 as from the bottom 12 spaced riser formed.
- a filter element having pores is located on the lid 21 of the second container 2 8 through the rinsing liquid into the discharge device 4 in the form of a line and got back to the processing point. Anything in the rinsing liquid Small cuttings stick to the outside of the filter element 8 and only the clean one Flushing liquid gets into the discharge device 4.
- the device 6 for generating the negative pressure is used, for example, by a Vacuum pump or a suction pump formed.
- the device 7 for generating the Overpressure is, for example, a self-priming impeller pump that works with a separate drive cooperates in the form of an electric motor.
- the device 7 for generating the excess pressure and the device for Generating the vacuum together with a single electric motor.
