- the industrial process for cleaning mechanical parts according to the invention is of the type consisting of spraying on said parts, while they are in motion, liquid products for washing and then rinsing them, then drying them by spraying them. air, and it is characterized essentially in that said washing and rinsing are carried out by means of the same product, which consists of a neutral pH compound consisting of an alcohol base, marketed by "OK WACK-CHEMIE GmbH” under the name “ZESTRON VD200”, and in that said product is used under particular conditions, namely that washing of the mechanical parts is carried out using said product at a temperature of between 45 ° C and 55 ° C.
- the method according to the invention also provides that said product is regenerated continuously, which limits the discharges.
- the present invention also relates to a device for implementing such a method, and which comprises an enclosure with a drum inside which said mechanical parts can be rotated and undergo the different phases of washing, rinsing and characterized in that it comprises a set of spray nozzles with flat jet nozzles for washing and / or rinsing mechanical parts, said assembly being connected to a centrifugal washing pump and a pump centrifugal flushing valve controlled by a valve, for projecting on the mechanical parts the liquid washing and rinsing product contained respectively in a washing tank and a rinsing tank each equipped with heating resistors and a means for controlling the flow rate of spray, and a set of pulsed hot air blowing ramps connected to a fan.
- the device comprises means for regenerating the washing and rinsing liquid product, defined by a three-phase decanter connected to the washing tank, to which the liquid washing and rinsing product is transferred to the a volumetric pump, and an evaporator connected to the decanter and the rinsing tank, while a tank makes it possible to recover the residues resulting from the decantation and the evaporation.
- the regeneration is obtained by means of centrifugation means.
- the invention relates to the field of the cleaning of mechanical parts, in particular intended to rid them of residues of greases, oils and other lubricants used during different phases of their manufacture.
- the subject of the invention is an industrial process, as well as a device for its implementation, making it possible to clean mechanical parts in accordance with the most recent legislation on environmental protection and waste management, with nevertheless a maximum degreasing efficiency and no additional cost.
- Such a method makes it quite conventional to submit moving parts of a movement to a wash, followed by rinse by spraying with a suitable cleaning agent before drying.
- the specificity of the invention consists in using, both for washing and rinsing, a neutral pH compound, constituted on an alcohol base, marketed under the name "Zestron VD200” by the company “OK WACK-CHEMIE GmbH”, in particular conditions including temperature.
- the mechanical parts concerned are thus installed to undergo the steps of the cleaning process in a receiving basket and then set up by an operator, via a manual or automatic conveyor, in the chamber 1 of the device according to the invention, preferably comprising a sliding door at the front, and equipped with a drum 2.
- This type of device is suitable for washing parts in the mechanical industry and especially specially designed to optimize the use of the product "Zestron VD200" in the context of the method according to the invention.
- the latter is carried out by jetting liquid washing product, while the mechanical part is driven in a rotational movement, either 360 °, or in alternating movement, along a horizontal axis through the displacement of the drum 2 in the enclosure 1.
- the liquid washing product spraying is provided by a set of fixed ramps with flat jet nozzles 3 in which the product is sent by a centrifugal washing pump system 4 integrated in the device, via a pipe 100, from a reservoir of washing 5 equipped with a resistance of heating for bringing the liquid to the required temperature, preferably between 45 C C and 55 ° C
- the effectiveness of the washing is increased by using a centrifugal pump 4 which provides a liquid washing product flow rate of the order of 45 m 3 / h with an adjustable pressure preferably set at around 17 bar.
- the rinsing of the parts is carried out in a similar manner inside the enclosure 1, by the projection of the same liquid product, via the set of ramps 3, into which the product is injected, through a pipe 101, by a centrifugal pump 6, from a rinsing tank 7.
- the present method preferably provides that the centrifugal pump 6 provides a flushing liquid product flow rate of 26 m 3 / h with an adjustable pressure preferably set at around 5 bars.
- the washing and rinsing phases are carried out through the same projection ramps 3, which the present invention provides for each time to be installed in pairs, respectively in depth above the drum 2, deep below the drum 2. , in height at the front and at the back of the drum 2.
- the present device thus comprises a three-way valve 8 permitting, as the case may be, the operation of the centrifugal pump 4 or the centrifugal pump 6, depending on the cycle to be considered, namely washing or rinsing respectively.
- the invention provides for continuous and closed-circuit filtration of the bath of liquid washing and rinsing product during the various washing and rinsing cycles.
- Filters 9 and 10 are thus used to retain large particles, they are of the mesh basket type and are placed on the gravitational returns of the solution after washing and rinsing, materialized, respectively, by a pipe 102 and a pipe 103.
- a finer filtration is also provided between the pump 6 and the projection ramps 3 in order to complete the cleaning.
- the device according to the invention is also equipped in series with pressure switches 12, 13 and flowmeters 14, 15 respectively output pumps 4 and 6.
- the filling of the washing tank 5 is preferably cascaded, via a pipe 104, from the rinsing tank 7, which itself is filled manually, and then leveled automatically via a valve 16 from a storage tank 17 monitored by a level detector.
- the washing and rinsing liquid product of the washing tank 5 is continuously agitated by the passage of the product in two ramps 18 equipped with nozzles to prevent the deposition of heavy particles.
- the flushing tank 7 is additionally equipped with an agitator and a probe for monitoring the pH with automatic temperature compensation, not shown.
- the drying of the mechanical part is provided by hot air drawn by a fan of a power of 5.5 kW through electrical resistors, via blowing ramps.
- the suction of the drying air is carried out inside the chamber 1 preferably and is filtered, which allows a significant energy saving.
- the present method further provides for the continuous regeneration of the washing and rinsing liquid product used for washing and rinsing parts.
- the liquid product contained in the washing tank 5 is transferred to the decanter 19 via a positive displacement pump 20, preferably having a flow rate of 40 l / h and making it possible to suck the product on the one hand at the top and secondly at the bottom of the tank, thanks to the valves 21, 22 respectively.
- the particulate filter 23 is thus intended to remove the solid particles, while the oils are decanted upwards.
- the liquid product is brought to a temperature below 30 ° C.
- This operation is performed by means of a heat pump type heat exchanger system 24 integrated in a pipe 105 that borrows the liquid product between the washing tank 5 and the decanter 19, to either trigger the heating of the washing tank 5, or the cooling of the decanter 19.
- the present process further provides for the introduction of a distillation system, by means of an evaporator capable of removing the remaining oil residues which do not have not decanted.
- the transfer of the product to be distilled takes place between the decanter 19 and the evaporator 25 via a pipe 106.
- the return of the condensate is carried out, via a pipe 107, between the evaporator 25 to the rinsing tank 7 which, by pouring, re-feeds the washing tank 5 and is reused for the cleaning of the mechanical parts.
- This system makes it possible to keep the product contained in the rinsing tank 7 clean, this always in the interest of maximum cleaning efficiency.
- the ultimate reprocessing consists in the incineration of the particles and oils recovered in a tank 26, placed at the outlet of the decanter 19 and the evaporator 25.
- the present method provides, in lieu of decantation followed by evaporation, to regenerate the product by separating it from the soil by centrifugation.
- the device according to the invention also has the advantage of a very simple use and allows a fast and easy work, managed by a PLC and an operator panel.
