However, the pressure of the quenching oil in the oil return pipeline is low, and the sediment causes a large pipe resistance of the oil cleaning equipment, which makes the oil on the working face overflow due to poor oil return.
In addition, the quenching oil contains a lot of hard slag such as scale, and these hard slag not only block the filter screen (because the hardness of the hard slag is even higher than the filter screen, it is very difficult to clean the filter screen blocked by the hard slag, and it is difficult to break the filter screen during cleaning. avoid), but if it is not cleared, it will not only block the pipeline and reduce the water cooling efficiency, but also cause the safe use of the oil supply pump

The invention discloses a working method of a decontamination device for an oil quenching production line, which is realized through the following steps: 1) When the quenching oil with slag in the oil return pipe (1) flows back from left to right, start the motor (14 ); 2) the motor (14) drives the water wheel (3) to rotate clockwise through the reducer (13), and the rotation of the water wheel (3) makes the fishing claw (4) installed thereon rotate thereupon. The invention can realize long-term continuous operation without being on duty; it is easy to serialize and can be applied to 40m 3 Requirements for slag removal at a flow rate of more than / h; under the condition that the returned oil does not overflow, the degree of cleanliness can be adjusted at will, and the highest degree of cleanliness can reach more than 75%; no heat will be generated during the process of slag removal , additionally the function of naturally cooling the oil temperature brought by the agitation of the oil, which can reduce the oil temperature by an average of more than 3 degrees Celsius; cascade installation can be realized.
Description
technical field [0001] The invention relates to the field of heat treatment equipment processing and manufacturing, in particular to a decontamination device for an oil quenching production line. Background technique [0002] For the oil quenching production site, the quality of the oil is directly related to the quenching quality. The faster an oil is cooled, the generally lower its viscosity and correspondingly lower flash point. And quenching with poorly cooled oil, no matter how good the quality of the oil is, the workpiece will have insufficient hardness after quenching, and the deformation will be large, resulting in quality claims. In addition, if the oil temperature is too high, it will cause unsafe accidents. At present, the oil quenching production line mostly uses a water cooling system to cool down the oil after quenching, so that the oil after quenching can be recycled. Obviously, the cooling degree of the quenching oil is directly related to the quenching qu...
