Definitions

  • Workpieces especially those that are grinded, Drilling, milling and the like have been processed often thorough cleaning to remove chips, abrasive grains, but also residues of processing fluids, such as cutting and cooling oils, or other processing residues to remove as completely as possible.
  • a cleaning liquid is particularly useful in metalworking Companies common: After processing blow off the workpiece by hand using a compressed air nozzle with the result that chips and other processing residues in the surroundings are blown, causing a highly distracting Pollution of the workplace. That's why it is already state of the art, a cleaning chamber with an over to provide a filter-equipped exhaust air opening into the Workpiece to be cleaned introduced and in which it by means one or more compressed air nozzles that come from the compressed air factory network be fed, cleaned, the exhaust air escapes through the filter into the workshop. That kind of Workpiece cleaning faces an improvement the previously described type of cleaning with a manual handled compressed air nozzle, since the exhaust air in all Rule loaded with processing residues despite the filter is, e.g. B. with vapors used in processing Cooling and / or cutting fluid, it also leads to one Impact on the hall atmosphere. Both procedures are also the disadvantage of high compressed air consumption in common.
  • DE-37 10 367-A1 describes a system for de-oiling workpieces become known by means of several compressed air jets; this system is also intended for machining Machining to remove oil from the chips, in both cases the system serves the purpose, in addition to the Avoiding the use of cleaning fluids in the Blow off removed oils and recover them for reuse to be able to supply.
  • this known system the goods to be de-oiled on a horizontally running endless conveyor belt put on, which is permeable to air and out a wire mesh or the like and a cleaning station passes through in the above the conveyor belt and in whose direction of rotation several as slot nozzles trained blow nozzles and under the conveyor belt, namely below the blow nozzles, a bowl-shaped air collector are arranged or is.
  • the latter and the blow nozzles are components of an air circulation system, which a Air high pressure pump in the form of a high pressure fan upstream the blow nozzles and an oil separator downstream of the Air catcher and upstream of the high pressure fan contains.
  • a Air high pressure pump in the form of a high pressure fan upstream the blow nozzles and an oil separator downstream of the Air catcher and upstream of the high pressure fan contains.
  • Each of the blow nozzles extends over the entire Transport width of the conveyor belt, and the same applies to the Air catchment container.
  • the delivery pressure of the high pressure blower is in the order of 5000 pa, and the air outlet speed between 30 and 70 m / sec.
  • EP-A-0 158 904 describes a blow-off system of dust from the surfaces of workpieces, such as for example to paint bodies, in the the workpieces to be cleaned in an at least essentially cleaned airtight sealed cleaning chamber will.
  • This well-known system has a channel-like lock chamber, which at both ends by an inlet side and an outlet-side lifting gate can be closed.
  • the lock chamber is one along the entire length of the the latter, arranged as a whole, stationary roller conveyor, on which the objects to be cleaned are placed and with which the latter moves through the lock chamber will.
  • the known system also has an air circulation system with a blower to convey air to two annular blow air channels, which in the longitudinal direction of the Lock chamber forming channel spaced apart are and each of which is formed by four straight segments which is in the interior of the lock chamber Protrude into the channel. Between the two blown air channels the lock chamber is equipped with an air extraction duct, downstream of the two air filters connected in series from which the fan sucks the air back out. The workpieces to be cleaned are removed using the roller conveyor clocked through the lock chamber.
  • the invention is based on the object, a dry cleaning system to create that allows in one continuous operation even such workpieces thoroughly to clean, which after processing impurities, such as chips, abrasive grains, residues from Machining fluids (cutting and cooling oils) and others Processing residues are cleared as completely as possible have to.
  • blowing nozzle or blowing nozzles must of course do so be ordered that they do not move the bulkheads hampers or hinder; for this purpose you become the blow nozzle expediently outside the inner surfaces of the channel walls arrange, with the blow nozzle opening with these inner surfaces can be flush, but in principle it would also be possible, the blow nozzle transverse to the direction of flow of the bulkheads mobile, e.g. B. pivotable to attach so that during of the cleaning process in the serving as cleaning chamber Channel segment protrudes, but be moved out of this can if a bulkhead is to pass through the blow nozzle.
  • blow nozzle out of the way of the bulkheads this should not be interpreted as if it were should always be the case, although the latter should be preferred is; in principle, it would also be possible to use the blow nozzle movable transversely to the direction of flow, e.g. B. pivotable to attach, so that during the cleaning process Channel segment currently formed for the cleaning process protrudes, but can be withdrawn from it if a bulkhead to pass the blow nozzle.
  • the endless conveyor element can have any shape as long as it is not the compressed air jet generated by the blow nozzle so annoying that it affects the cleaning result becomes; it would be z. B. conceivable as an endless conveyor endless rope to use, on the longitudinal distance from each other arranged holding devices for the workpieces attached are.
  • the endless conveyor element also act as a conveyor belt on which the workpieces are placed and which are permeable to air across the belt level is, e.g. B. because the conveyor belt of a relative wire mesh having large openings is formed.
  • the endless conveyor element is formed by a conveyor chain that is articulated from several Chain links exist and on which the workpieces are placed be, of course, also several, side by side arranged and parallel conveyor chains can provide, since such a structure transversely to the direction of flow is permeable to air.
  • the blow nozzle arrangement could be made as shown in DE-37 10 367-A1; such an arrangement but has the disadvantage that the compressed air jets always only directed in one direction at the workpieces to be cleaned are what often do not give optimal cleaning results will lead. Therefore it is preferable if the Blower nozzle at least essentially the workpiece to be cleaned enclosing air outlet opening, the Course of the particularly slot-shaped air outlet opening - Seen in the direction of the workpieces - advantageously the workpiece contour is adjusted.
  • blow nozzle is one of those cleaning workpiece at least essentially enclosing, d. H. an at least almost annular air outlet opening and has moved the workpieces by means of an endless conveyor element should, the endless conveyor element through the Extend the air outlet opening of the blow nozzle.
  • the length of the chamber could be the cleaning station formed channel can be only slightly larger than the longitudinal distance of the attached to the endless conveyor Bulkheads or partitions; this is sufficient if the endless conveyor element during the actual cleaning process stopped or moved very slowly.
  • the channel length is much greater than the longitudinal distance between two successive Scots, especially with relatively high throughput speeds to be able to work.
  • offers such an embodiment has the advantage that the bulkheads in Channel one after the other several at least almost airtight Form duct segments, so that the exhaust air outlet if necessary to reduce the area even further and / or additional or before cleaning the workpieces Workpiece treatments in a closed treatment room to be able to perform.
  • Superheated steam jet nozzle in the direction of flow in front of the blow nozzle to arrange.
  • a hot steam jet of approx. 140 ° C and 5 bar to work.
  • the high-pressure pump in such a way that it delivers at least about 600 m 3 / h per blowing nozzle, and a side-channel compressor is preferably used as the high-pressure pump - such side-channel compressors are known and available on the market, so that no further description of such a compressor is required.
  • This process can also be easily automated, by the pressure drop across the filter or downstream the high pressure pump the pressure of the generated by it High pressure air flow measured, the pump switched off briefly, the dirt discharge opening of the dirt collecting container opened and the downstream side of the filter with compressed air is applied when the pressure drop across the filter certain size exceeds or the pressure behind the high pressure pump falls below a predetermined value.
  • the subject of the invention also a method for cleaning workpieces by means of at least one compressed air jet in which the workpiece brought to a cleaning station by means of a Air high pressure pump generates a high pressure air flow, this a blowing nozzle directed towards the workpiece and Exhaust air is returned to the suction side of the pump via a filter is, according to the invention the workpiece in one to an air inlet in the form of the blow nozzle and an exhaust air outlet at least essentially airtight chamber cleaned and the air in a closed, the chamber containing air circulation system is circulated, and wherein also upstream of the pump solid particles from the air flow mechanically filtered out.
  • the Invention even more so that a high consumption of one Factory network compressed air can be avoided and that the Operation of the high pressure pump takes place more energy-efficiently because the all air conveyed by the latter again on the suction side is fed to the pump and at least the high pressure pump do not suck in any significant quantities of ambient air and must condense.
  • this air is heated and hot air is supplied to the blow nozzle what has a positive effect on the cleaning result, and not only with regard to one if necessary required de-oiling or degreasing, but also if the workpieces to be cleaned or the cleaned workpieces also need to be dried for some reason.
  • the cleaning system not just as pure Use dry cleaning system - after wet cleaning there is the possibility with an inventive Plant to dry the workpieces and, if necessary, to clean them, a system according to the invention can also without be trained so that the workpieces in it first pre-cleaned dry, then using a cleaning liquid cleaned and finally dried such embodiments are particularly recommended in which in a channel formed by the chamber Bulkheads several closed channel segments in a row be formed.
