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.
- Fig. 1 shows parts of a whole designated 10 Conveyor, of which only the upper run 12 of an endless conveyor chain and a support or deflection roller 14 (which is possibly also be a roller) were.
- a cleaning station 16 has an elongated, straight one Channel 18, the front and rear, d. H. 1 on the left and is open on the right, a rectangular cross section (see Fig. 2) with constant cross-sectional area over its entire length has and shape and the walls except one position to be described are closed everywhere.
- Fig. 1 shows only a few of these Partitions or bulkheads, namely bulkheads 20a, 20b, 20c, 20d and 20e, like all the others, not shown and bulkheads attached to the conveyor chain at equal intervals arranged from each other and formed identically are.
- each bulkhead should be so smooth Adjusted inner surfaces of the channel 18 formed channel cross section be that as long as it is in channel 18, at least almost airtight against the inner surfaces of the channel side walls (if necessary with the help of the bulkhead edges attached, not shown grinding seals), so that two consecutive and just in the Channel 18 bulkheads together with the channel walls form an at least almost airtight space, hereinafter referred to as the channel segment.
- each bulkhead has a gas-impermeable wall through which the Conveyor chain is passed gastight.
- the upper run 12 of the invention runs Conveyor chain only a short distance above the lower wall 18a of the channel 18 so that workpieces to be cleaned on the upper Run 12 of the conveyor chain and so on convey through the channel 18.
- the direction of funding or the running direction of the upper run 12 of the conveyor chain was indicated in Fig. 1 by the arrow "F", and a to The cleaning workpiece "W” is on the left of the channel 18 in FIG. 1 a workpiece W was also dot-dashed in FIG. 2 indicated.
- This blow nozzle has an annular nozzle body 30a, which runs around the channel 18 and one in itself forms closed annular cavity 30b. Also forms the nozzle body 30a is again an annular outlet nozzle 30c with a likewise annular nozzle slot 30d, which is the outlet opening of the blowing nozzle 30. As can be seen in FIG. 3, the nozzle slot runs 30d around the entire channel 18 because the outlet nozzle 30c into the lower wall 18a, the upper wall 18b and the two Side walls 18c and 18d of the channel 18 is inserted and with flush with the smooth inner surfaces of the channel walls.
- the outlet nozzle 30c and thus the Nozzle slot 30d with respect to the longitudinal direction of the channel 18 inclined, namely against the conveying direction F, it has proven to be appropriate to choose this inclination so that the compressed air jets emerging from the blowing nozzle 30 P (see Fig. 3) with a perpendicular to the conveying direction F oriented plane an angle of the order of 10 form up to 30 ° and preferably from about 15 °.
- this includes an air high-pressure pump 34, an area of the canal to be discussed later 18, a silo-like dirt collecting container 36 and connecting pipelines 38, 40 and 42.
- the direction of conveyance of the High-pressure pump 34 was indicated by the arrow L.
- the collection container 36 contains just before the connecting pipeline 42 an in particular sieve-shaped solid particle filter 44, above this filter, i.e. H. on whose Downstream side, one with a opens into the collecting tank 36
- Compressed air line 48 provided with valve 46, below is the collecting container provided with a slide valve 50 through which one Dirt discharge opening can be formed, and approximately in middle area of the collecting container opens into this Connection pipe 40 a.
- At 52 was accumulated in Fig. 1 Dirt indicated, which through the filter 44 the circulated air flow has been separated and which already has fallen off the filter.
- the connecting pipeline 40 includes a valve 40a that Connection pipe 42, a valve 42a and the connection pipe 38 a pressure switch PS and a pressure gauge PI.
- the high-pressure pump 34 is a so-called side channel compressor with an output of the order of 10 kW, a delivery rate of approximately 750 m 3 / h and a delivery pressure of approximately 200 mbar.
- the volume of the dirt collecting container 36 is approximately 150 l, and the filter 44 is designed such that the maximum filter load (air flow volume) is of the order of 800 m 3 / h.
- one of the pulleys or rollers of the conveyor must be 10 be driven, e.g. B. the one shown in FIG Deflection roller 14.
- the exhaust air including all impurities blown off the workpiece, enters the funnel 50 and thus into the connecting pipeline 40 - during the cleaning process, the valves 40a and 42a are open, while the valve 46 and the slide valve 50 are closed.
- the filter 44 separates the solid particles from the air flow circulated with the aid of the high-pressure pump 34, while oil residues are previously separated from the air flow with the aid of an oil separator (not shown) (suitable oil separators, which can be, for example, an electrostatic separator, are known from the prior art).
- the exhaust air is then compressed again by the high-pressure pump 34 and conveyed to the blowing nozzle 30.
- the cleaning process begins in the next chamber segment, d. H. cleaning the next workpiece.
- the pressure switch PS responds, whereupon a system control, not shown, the high pressure pump 34 switches off, the valves 40a and 42a closes and the valve 46 as well as the slide valve 50 opens what a Clean filter 44 by backwashing and discharging of the dirt collected in the collecting container 36 by the Slider valve 50 causes. Then the valves 46 and 50 closed, the valves 40a and 42a opened and the high pressure pump 34 put back into operation, so that the Cleaning process can be continued. During one Cleaning the filter 44, the conveyor 10 is expedient also turned off.
