Definitions

  • the invention relates to a cleaning and coagulation device for cleaning tools or components with paints, varnishes, coolants, abrasives, degreasing agents or the like and for separating the resulting wastewater into clear water and contaminant residue, for example paint sludge, consisting of a basic housing with a cleaning basin, a stirring device arranged in the cleaning basin with a stirring tool, a collecting container for receiving the clear water from the cleaning basin and a filter for filtering out residues of the waste water which can be conducted from a drain tap of the cleaning basin into the collecting basin.
  • a cleaning and coagulation device for cleaning tools or components with paints, varnishes, coolants, abrasives, degreasing agents or the like and for separating the resulting wastewater into clear water and contaminant residue, for example paint sludge, consisting of a basic housing with a cleaning basin, a stirring device arranged in the cleaning basin with a stirring tool, a collecting container for receiving the clear water from the cleaning basin and a
  • soiled tools are rinsed off with a water spray, the waste water being collected in the cleaning basin.
  • flocculants, splitting agents or other separating aids are stirred in for the purpose of separating the waste water into clear water and dirt components.
  • the resulting mixture can then be passed into a filter, in which case the filtered-out constituents can be disposed of or processed and the clear water is collected in order to repeatedly feed it to the process.
  • Cleaning and coagulation devices of the type mentioned are known in the form of large stationary systems which have cleaning basins with a capacity of approximately 200 to 2000 liters. In addition to color wastewater treatment, they are also used in industry for the preparation and disposal of coolant emulsions, degreasing solutions, painting, grinding and other wastewater. They are not suitable for use in small businesses, for daily cleaning of small quantities of tools, for example dirty paint processing tools in paint shops, and for environmentally friendly separation of the waste water.
  • the large stationary systems have permanently installed stirring devices which require a certain fill level in the cleaning basin in order to be able to stir in the separation aid properly.
  • Their cleaning basins have shapes whose cross-sections decrease more or less as the depth of the basin increases from the opening to the bottom.
  • a system with a large reduction in cross-section with increasing depth of the cleaning basin results in better stirrability and a short stirring time for the separation aid, but a comparatively low capacity in relation to the space required for the cleaning basin.
  • a system with a small reduction in cross-section with increasing depth of the cleaning basin has a comparatively large capacity, but has a poorer ability to be stirred in and a longer stirring time of the separation aid into the waste water.
  • the object of the present invention is therefore to create a small cleaning and coagulation device for daily use in small businesses, in which, due to the shape of the cleaning basin, the ability of the separating aid to be stirred into the waste water and the capacity of the cleaning basin are optimally coordinated with one another .
  • the cleaning basin has a first side wall arranged approximately perpendicular to the top opening, a second side wall opposite it, inclined towards it, and a third and fourth side wall adjacent to the first and second, the opposite side wall are arranged and approximately are evenly inclined to each other.
  • the proposed basin shape Due to the constantly changing distance of a point of the stirring tool to the adjacent wall of the cleaning basin during a stirring tool revolution, turbulences arise in the flow of the sewage in the cleaning basin, which cause the separating aid to be optimally stirred into the sewage.
  • the proposed basin shape has an approximately 25% larger capacity than when using a precisely pyramid-shaped basin.
  • the cleaning basin can consist of sheet metal, or it can consist of salt water-resistant plastic, for example polypropylene, which leads to a light construction of the cleaning basin.
  • the cleaning basin has a narrow bottom wall compared to the opening on the top. This measure prevents a fluidic dead water area from forming in a narrow gap at the bottom of the cleaning basin, in which the wastewater is not mixed with the separation aid. Furthermore, this measure makes it easier to attach a drain tap to the underside of the cleaning basin.
  • the bottom wall is inclined from the first to the second side wall and is provided with the drain cock at its lowest point, in the vicinity of the second side wall. This ensures a rapid and residue-free discharge of the waste water into the filter.
  • the stirring device is provided with an adjusting device with which at least the immersion depth of the stirring tool in the cleaning basin can be adjusted.
  • the device can thus be set to any filling level in the cleaning basin and the separating agent can be stirred into the waste water without problems.
  • the adjusting device simply consists of an outer tube, in which an inner tube is arranged such that it can be moved and locked, the inner tube having a receptacle for the stirring device.
  • the stirring device can consist of a stirring guide which is present in every small business and which is accommodated in a commercially available hand drill, the hand drill being mountable in the receptacle of the inner tube.
  • a stirring device that can be operated with low voltage is expediently provided as the stirring device.
  • a pneumatically driven stirring device is used as the stirring device.
  • the cleaning and coagulation device can be moved with the aid of rollers.
  • these are arranged on the underside of the basic housing.
  • the collecting container also has rollers
  • the basic housing is provided with a dividing surface for the collecting container, which is arranged between the rollers of the basic housing and is at a small distance from the floor in comparison to the diameter of the rollers of the collecting container. In this way, the collecting container can be easily moved into and out of the basic housing.
  • a pump is arranged in the basic housing, which projects into the collecting container on the suction side and is provided with a water shower on the pressure side via a hose.
  • the clear water in the drip pan is used for many cleaning cycles. Consequently drinking water can be saved.
  • Various types of energy supply units for the pump can be attached to the basic housing, such as, for example, an electrical mains connection for connecting an electrically drivable stirring device to an energy source or a pneumatic maintenance unit for connecting a pneumatically drivable stirring device to an energy source.
  • the cleaning and coagulation device can be used in rooms where there is a risk of explosion.

  • a stirring tool for stirring the clear water 7 from the cleaning basin 3 and a filter 8 for filtering out colored sludge parts which can be conducted from a drain tap of the cleaning basin 3 into the collecting container 6 Color waste water.
  • the filter 8 lies in a sieve 9, which is inserted into the opening of the collecting container 6.
  • the cleaning basin 3 has a first side wall 11 arranged approximately perpendicular to the opening 10 on the top.
  • the slight deviation of the side wall 11 from the above-mentioned vertical position to the opening 10 on the top represents a slight draft bevel Ila for shaping the cleaning basin 3 produced in the deep-drawing process from the deep-drawing tool.
  • the first side wall 11 is opposite a second side wall 12 inclined towards it.
  • a third side wall 13 and a fourth side wall 14 adjoin the first and second side walls 11, 12, which are arranged opposite one another and are inclined approximately uniformly to one another.
  • the cleaning basin 3 has a long, narrow bottom wall 15, the narrow dimension of which is just large enough to accommodate a drain tap 16. It extends in its long extension between the first side wall 11 and the second side wall 12 and has the drain tap 16 at the deepest point of the cleaning basin 3, which is arranged in the vicinity of the second side wall 12.
  • the stirring device 4 can be adjusted at least in its immersion depth by means of an adjusting device 17 in the cleaning basin 3.
  • the adjusting device 17 of the stirring device 4 is provided with an upright outer tube 18, in which an inner tube 19 is displaceable and can be locked by means of a clamping screw 20.
  • the inner tube 19 has a receptacle 21 for the stirring device 4.
  • the stirring device 4 is in the described embodiment Example from a whisk 23 held in a commercially available hand drill 22, the hand drill 22 being mountable in the receptacle 21 of the inner tube 19. If the cleaning and coagulation device 1 is to be used, for example, for cleaning solvent-containing impurities, a pneumatically or low-voltage stirring device is used.
  • the cleaning and coagulation device 1 can be moved by rollers 24 arranged on the underside of the basic housing 2.
  • the collecting container 6 also has rollers 25 arranged on the underside.
  • the basic housing 2 is provided with a dividing surface 26 for the collecting container 6, which is arranged in between between the rollers 24 of the basic housing 2 and has a small distance from the floor in comparison to the diameter of the rollers 25 of the collecting container 6.
  • a pump 27 is arranged in the basic housing 2, which projects on the suction side with a suction pipe 28 into the collecting container 6 and is seen on the pressure side via a hose 29 with a water shower 30.
  • An electrical power supply unit for the pump 27 in the form of a mains connection socket is provided on the basic housing. This can also serve as a connection for the electric hand drill 22 of the stirring device 4.
  • a low-voltage voltage supply or a preferably pneumatic pressure medium connection can be provided for use in an inflammable atmosphere.
