Cochlea washers
The cochlea washers are machines used for continuous washing or degreasing of small and medium-sized parts. It is an ideal machine to be connected directly to the output of a production equipment such as a lathe or a stamping line.
Its operation is based on a tunnel with an internal auger, with a determined number of turns depending on the size of the parts to be treated. This auger rotates at an adjustable speed, transporting the parts along the entire length of the equipment.
Work process
Depending on the contaminant contained in the parts and the type of metal to be washed, the machine can be equipped with different stages. For example, for a brass part that contains coolant, an initial cleaning with hot water is performed followed by a drying process. In case the part contains oil, a three-phase process is designed, firstly degreasing, secondly rinsing and finally drying.
All phases of the machine are temperature controlled by a digital thermostat. A mesh filter is installed in each treatment tank to retain shavings and small particles so as not to affect the washing of subsequent parts and to prevent clogging of the sprinklers during the spraying phase.
Specific equipment for parts degreasing
In a degreasing equipment, the first three or four vacuums maintain the parts with complete immersion. Subsequently, they pass through a stage equipped with sprinklers that direct the degreasing product with a certain pressure on the parts, which are permanently in motion. This is followed by a rinsing phase to remove any remaining degreasing product and finally drying.
Normally the degreasing tanks are communicated without mixing of products so that their levels can be regulated when necessary. For this reason, the level detector is activated in the degreasing tank, water will automatically flow from the rinsing tank to the degreasing tank and the rinsing tank will receive water from the mains by means of a solenoid valve.
When defining an installation, it is important to adjust the dosage of the material to be washed inside the cochlea. The parts in each loop must have enough space so that degreasing, rinsing and drying air can reach all parts of them.
Other Applications
This type of machines can also be used for the application of phosphates with all their corresponding phases and also for the impregnation of a product on the parts, since there are complete immersion machines available.
In addition to the standard machines, Coniex supplies all types of machines for any process and can even combine spraying and immersion phases simultaneously in the same machine.
