title

Device for cleaning oil or grease soiled machine parts.

Technical environment

The invention relates to a device for cleaning with oil or grease soiled machine parts such as motor vehicle parts or the like in the manner of a dividing table that includes a trained as a work surface with recessed in the drain drainage or cleaning area in which the individual part with a can be sprayed with microorganisms treated cleaning medium, and wherein below the working surface designed as a bio-reactor container for receiving the enriched with the soil particles medium is arranged, in which the medium is heated by means of a Heizeinπch- device, and wherein the medium by means of a pump on circulating a discharge in the working area with a nozzle or brush.

So-called partial proofing washers have been developed to purify items contaminated with organic waste products. These conventional parts washing machines usually use chlorine solvents, benzine, other organic solvents, aqueous detergents or mixtures of surfactants as rhyming fluids. These known parts washer have the problem that the disposal of the Reimgungsflussigkeit used is extremely problematic due to their ingredients.

State of the art

For example, from the prior art Teilereimgungsge rates are known which use a wash fluid offset with a biological agent to replace in this way benzine and chlorinated solvent. Such Teilereimger is known for example from DE 29522341, in which microbiological Teilewascher a closed system for cleaning motor vehicle parts, equipment parts and machine parts is known, consisting essentially of a first chamber for cleaning the parts by bringing into contact with a wassπgen Liquid. In this case, a second chamber is provided which contains the liquid and accommodates a plurality of living microorganisms which biodegrade the organic material in the liquid. The liquid is pumped from the second chamber to the first chamber to be available for the cleaning of the parts, wherein it flows from the first chamber to the second chamber again. For this purpose, a drain at the bottom of the first chamber is designed such that below the drain, the washing liquid is enriched with microorganisms. Due to this design results in a closed cleaning system, which is mixed with microorganisms, wherein the liquid is then fed via a pump back to the winding area, in which then the soiled parts are cleaned.

task

In these Teilereimgungstisch known in the prior art, it is considered disadvantageous that in particular due to the circumstances of the table, a mechanical cleaning of the parts can be made only with the brush, for example. It is not possible to unwind the parts under pressure with a rubbing fluid, in order to radiate the particles from the part in this way. However, it is often desired that particularly stubborn adhering dirt should be removed from the machine parts.

It follows from the object underlying the invention to further develop a device for cleaning oil or grease soiled machine parts in the manner of a part of the rule table whose cleaning efficiency is much better.

This object is achieved according to the invention by the main claim 1; advantageous developments of the invention will become apparent from the dependent claims.

solution

Due to the design, in particular the dividing table with a set on the work surface designed as a housing cover, in the front side a transparent surface is arranged below the Eingπffsoffnungen for handling the parts to be cleaned is arranged, brings in particular the advantage that with a material higher pressure can be used without liquid can escape from the area of Teilereimgungstisches. Thus, it is now possible with high pressure and a mechanical action by means of the cleaning medium to act on the parts, so that a much higher efficiency in the Cleaning is achieved. Because it is precisely with stubborn caking 01- and fat residues on machine parts that there is the possibility that with a pressurized high-pressure jet of Reimgungs- liquid here the hartnackigen areas can be solved by the machine parts. For handling the machine part to be cleaned below the cover, a viewing window is provided, through which the part can be observed, whereby the user has sufficient handling freedom through the openings to clean the part. The user is thus protected from splashes.

In a further development of the invention, the front side of the housing is designed as a hinged flap, so that a quick change of the cleaned part can be made. In a further development, in particular of the housing, this has a base frame, which rests in the mounted state on the working surface on the one hand and on the other hand, the edge partially covered. This results in a form-fitting housing or attachment to the frame of the cleaning table. In this case, the rear wall of the housing extends in extension of Behaltnisruckwand the bioreactor, wherein the side walls are formed as triangular faces, so that there is a running under a bevel Rahmenoffnung on which the flap is pivotally mounted. The flap itself is mounted on the Rahmenoffnung means of parallel pivoting bracket on the Rahmenoffnung. Thus, the flap can be pivoted up so that the entire opening area becomes free in order to insert or remove the part to be cleaned. In order to prevent an automatic loosening of the flap of the frame opening area, a closure element designed as a bracket is arranged laterally in the region of the side wall of the flap.

The flap is hood-shaped, the side walls and the upper rear wall run under a slope, wherein the front wall extends in extension of Behaltnisvorderwand the bioreactor, so that there is a window located under a bevel. Because of this oblique design, in particular the flap or the transparent window area, there is therefore the possibility that the user can see from above on the part, in order to effect an efficient cleaning in this way.

In a further development of the invention, the Einπffsoffnungen are arranged for handling in the front wall of the flap, which consists of a provided with horizontal and vertical slots elastomeric Material exist. Thus, in particular, the housing is adapted to the working position of the user, so that the hands or the arms can be inserted through the front in a simple manner, which are not hindered by the elastomeric material with their slots in the freedom of movement. Prevention gives good visibility into the table area, so that efficient cleaning can be carried out. In order to handle the flap easily handle elements are provided on the front wall of the flap above the Einπffsoffnungen means of which one can easily and easily pivot the flap, after which the locking lever is unlocked.
