Definitions

  • the innovation relates to a device according to the type of protection claim 1.
  • both containers are known in which the machine parts to be cleaned are lowered into a washing liquid, and also cleaning devices such as that of DE-GM 1 962 757, in which washing liquid is removed from a reservoir by means of a pump and onto which parts to be cleaned is injected and then, collected by an outlet, is returned to the reservoir via filter devices.
  • cleaning devices such as that of DE-GM 1 962 757, in which washing liquid is removed from a reservoir by means of a pump and onto which parts to be cleaned is injected and then, collected by an outlet, is returned to the reservoir via filter devices.
  • the cleaning effect is determined only by dissolving and softening them and is therefore inadequate, regeneration of the washing liquid is difficult, and due to the extensive filling of the washing chamber with a cleaning liquid there is an undesirably high weight.
  • the device according to DE-GM 1 962 757 has moderate dimensions and a lower weight, the open spraying of the cleaning liquid limits the intensity of the cleaning jets, and even with liquid sprayed with only low energy, an undesirable odor nuisance as well as a considerable pollution of the surroundings due to the dropping off of liquid drops.
  • the often proposed ultrasonic cleaning results in high mechanical stresses for sensitive parts, which they are often not up to.
  • electronic components and type wheels of printing units react to ultrasonic cleaning processes due to hairline cracks and early failure.
  • the washing liquid required in large quantities quickly becomes dirty and causes considerable procurement costs and disposal difficulties.
  • the innovation is based on the task of creating an arrangement of the designated type in which the operating personnel are relieved and at the same time the respective location can be selected without problems by improved regeneration of the cleaning agent in connection with a restriction on the towing thereof.
  • the separation of the cleaning agent contained in the exhaust air is also improved by the structure of the downstream filter.
  • Figure 2 is a partially broken front view.
  • a substructure 2 On fixedly mounted or rotatable or pivotable and advantageously also lockable castors 1, a substructure 2 is provided, which carries a cleaning chamber 3, the loading opening of which is closed by a door 4, which by means of hinges 5 upwards can be folded away and placed on rubber buffer 6.
  • the cover plate of the cleaning chamber is equipped with a viewing panel 7, for example made of acrylic glass, just as the door 4 is closed by a front panel 8 which has an opening 9 for inserting and engaging the
  • a perforated turntable 12 is supported on an axle pin 10 in the cleaning chamber, supported by a thrust bearing 11, for setting up the items to be cleaned, which turntable can be locked by means of a locking device (not shown). This can brake the turntable or its hub by friction or engage lockingly in holes thereof.
  • the cleaning chamber is closed by an impact filter 13, which is removable and consists of at least two packages of slotted disks connected to one another.
  • a manifold 14 is used to extract exhaust air, and liquid that is sprayed onto the floor 15 of the cleaning chamber 3, which can easily fall off towards the door 4, and, if necessary, dripping from the impact filter 13, can run into a filter housing 16 which is provided with a is also provided as a slotted disc filter plate 17, but can also be designed as a narrow line filter, for example with a mesh size of 1.20 mm.
  • the bottom 18 of the filter housing rises slightly to the side and has two openings 19 in the center.
  • Linear guides 20 are provided on the underside of the filter housing 16, in which a filter attachment 21 is provided by means of a button that can be pulled out by means of a not shown locking device the operating position shown is fixed.
  • the filter attachment 21 has, in each case below the openings 19, two support cones 22, in each of which paper filters 23 are inserted;
  • conventional coffee filters can be used here, which ensure excellent regeneration of the cleaning liquid and can be carried out in " two-
  • a parallel arrangement can also cope with stronger liquid flows.
  • a normally open drain valve 24 is arranged in the bottom of the filter attachment 21, via which the regenerated cleaning liquid is returned by means of the hose 25 into a container 26 placed on the standing surface 27.
  • the spray gun (not shown) used for cleaning can be operated from the same container.
  • a blower 30 operated by means of an electric motor 29, which is blown into the compensation chamber 31 arranged in the lower part of the substructure 2 and is able to calm down here , coarse, medium and even fine droplets of the cleaning agent are able to precipitate out and form a sump in the lower part of the compensation chamber 31.
  • a frame 32 which extends over the entire cross section of the substructure 2, a number of filter mats 33 are provided, which are knitted from metal wire and, due to their strong packing, form a tight-meshed baffle filter.
  • a collecting space 34 in which the air quantities passing through the filter mats 33 with a relatively low flow speed and over a large area are collected and further cleaned by droplets dropping out.
  • the liquid residues that precipitate here also fall down into the filter mats 33 and, with the cleaning liquid collected by them, into the sump of the compensation chamber 31, from which the liquid present there is withdrawn periodically, for example weekly or monthly, via a drain valve 35 can be.
  • a small rotor pump similar to that of a windshield washer system of a motor vehicle, to also periodically pump the liquid present over the
  • an exhaust space 36 is partitioned off by means of a shield plate 37.
  • the air which is still calmer here and cleaned by precipitation, can escape through the overpressure in the collecting space 34 via the elbow 38, the exhaust hose 40 connected to its flange 39 and an activated carbon filter 41.
  • the exhaust air in front of the activated carbon filter is cleaned even more extensively, so that its efficiency increases as well as its service life. Due to the gap formed in front of the screen 37 and the flow resistance of the activated carbon filter, the air flow passing through it remains low.
  • the major portion of the air sucked in by the blower 30 is returned to the cleaning chamber via two elbows 43, two return hoses 44 and two guide sleeves 45 and expediently by means of return nozzles 46 which are rotatable and adjustable in height in the guide sleeves 45, at least after the cleaning has been completed the pre-cleaned workpiece directed so that a quick drying of the same is achieved.
  • Both the compressed air and the spray gun can be supplied with compressed air via a predefined compressed air network, by storage or by a compressor, which can be set up remotely from the device, if necessary.
  • the connection is made via a fitting which, however, is expediently not on the rear, as shown, but on a flank of the arrangement.
  • REPLACEMENT LEAF is arranged, expediently that edge which is opposite the maintenance flap 47.
  • This maintenance flap can be pivoted, but it is also possible to fasten it with screws.
  • it can optionally be connected to the frame 32 if it is held so as to be extendable via a linear guide.
  • the compressed air fitting is designed as a water separator 48, which is equipped with a pressure reducing valve 49 and a shut-off valve 50 and expediently also has a pressure gauge (not shown) or is connected to it.
  • the water separator 48 is provided with two connections 51 and 52 in order to be able to connect both a compressed air pistol and a spray pistol.
  • the separator housing 53 is expediently provided with a filter. Paper filters can also be used here; Cotton filters, for example, have proven useful, e.g. can be introduced in the form of a tampon and bring about the necessary cleaning of the compressed air.
  • the connecting cord for the electrical connection can be provided at the free end with a conventional Schuko plug and connected in the connection box 54, which can also be equipped with a mains switch, if the latter is not provided for better accessibility on the sides or the front of the arrangement .
  • riser pipes 55 are provided in the cleaning chamber on both sides of the turntable 12, which end in a spray nozzle 56 and which, in the area of a spray line, are preferably provided with further spray nozzles directed towards the turntable.
  • These spray nozzles can be inserted, pressed in or screwed in, but they can also be directed bores
  • REPLACEMENT LEAF be executed.
  • a drive device 57 that rotates slowly, which can consist of an electric gear motor arranged behind the cleaning chamber, a connecting shaft and an angular gear, it is achieved that practically all surface areas applied to the turntable also for the items to be cleaned Detergent jets can be reached.
  • the riser pipes 55 are fed by a water pump 58 and a valve 59 arranged downstream of the latter, the suction connection of the water pump 58 being guided into one of the containers 26.
  • the automatic mode of operation can be set on the switch box 60, which has several setting elements by means of which the time of the spraying, i.e. the effectiveness of the water pump 58, and that of drying can be adjusted via the return nozzles 46, and by means of which the speed of the drive device 57 of the turntable 12 is also advantageously determined.
  • a limit switch 61 is also advantageously provided, which detects the opening of the door 4 of the cleaning chamber 3, for example via an angle lever connected to the hinge, and at least prevents spraying operations after a short opening stroke, and expediently also interrupts the air circulation in order to prevent the escape of To prevent air containing cleaning agents from the open cleaning chamber. It was also found to be expedient to design one of the rollers 62 as a switchable brake roller in order to achieve a defined state of the arrangement. The work is facilitated by a lamp 63 provided above the cleaning chamber 3 and illuminating it through the lens 7. In a pipe connected to the rear of the cleaning chamber, a telescopic boom 64 is arranged, which can be pulled out and adjusted in height, which allows the desired height of the active
  • the objects to be cleaned are applied to the perforated turntable 12 or the turntable 12 formed from wire mesh; if necessary, this can be done, for example in the case of printed circuit boards, by means of special holding devices adapted to these.
  • the door is pivoted back into the illustrated working position, and a compressed air gun 67 can first be inserted through the opening 9 of a relatively small cross section in order to blow loose dirt and dirt off the objects to be cleaned.
  • the water pump 58 is then switched on in order to effect a first cleaning of the items to be cleaned.
  • the required soaking is achieved with a certain service life, and then the items to be cleaned are sprayed in again by means of the spray liquid, the detached contamination components, such as partially resinified oils, being sprayed off after soaking.
  • the turntable 12 with the items to be cleaned is continuously rotated by switching on the drive device 57, so that the jets of the spray nozzles 56 reach them from all sides.
  • a final overmolding ensures the desired cleanliness.
  • Superficial drying can first be effected by repeated use of the compressed air gun 67, by means of which still adhering parts and dripping cleaning fluid can be blown off. An even longer stay
  • REPLACEMENT LEAF in the cleaning chamber when the fan is operating allows for complete drying, although even with electronic devices the complete conductivity of the cleaning liquid used is not absolutely necessary because of the complete drying.
  • the opening 9 is designed in such a way that, on the one hand, practically undisturbed working with the compressed air and the spray pistol is possible, on the other hand but not too much outside air enters.
  • the low negative pressure which arises in the cleaning chamber 3 is used to prevent any escape of droplets or vapors of the cleaning agent to the outside: through the opening 9, a small air flow will always flow into the cleaning chamber and thus the air already in it push back towards the impact filter 13 and the manifold 14.
