The wire drawing oil after impurity removal is stored in the impurity removal box 91, and the impurity removal box 91 is not controlled by the driving motor 93, so the wire drawing oil stored in the impurity removal box can directly flow into the oil storage box 1 through the oil outlet and the oil pipe 2 for next cooling and standby.
And the upper part of the impurity removing roller 92 is connected with the wire drawing machine 4 through an oil pipe 2. The drawing oil passing through the drawing machine 4 needs to directly flow into the trash removal drum 92 and should be prevented from directly flowing into the trash removal box 91, and thus the oil pipe 2 is connected to the trash removal drum 92 instead of the trash removal box 91.
The filter layer 10 is a mesh filter layer 10 or a filter paper filter layer 10. The purpose of the filter layer 10 is mainly to remove impurities in the drawing oil, which are generally debris generated during the drawing process of the copper wire, so that the meshes of the filter screen should be as small as possible, or multiple layers of screens are alternately stacked to reduce the pore size of the meshes. If filter paper is used for the filter layer 10, the filter paper is rated 35 to 45 μm and cannot be lowered any more, otherwise the drawing oil is destroyed.
In addition, the bottom of the impurity removing box 91 is provided with an oil outlet, and the oil outlet is connected with the oil storage tank 1 through an oil pipe 2. The wire drawing oil after impurity removal is stored in the impurity removal box 91, and the impurity removal box 91 is not controlled by the driving motor 9393, so the wire drawing oil stored in the impurity removal box can directly flow into the oil storage box 1 through the oil outlet and the oil pipe 2 for next cooling standby.
The working principle of the wire drawing oil cooling device with the impurity removing function in the embodiment is as follows:
a wire drawing oil circulation circuit: drawing oil is taken out through oil pump 3 in following the batch oil tank 1 to carry and lubricate and cooling operation to copper line wire drawing process in the wire drawing machine 4, the drawing oil that uses up flows into edulcoration device 9, carries out the edulcoration to the drawing oil that falls into metal debris and handles, then cools off in flowing into batch oil tank 1 again, and the drawing oil is all carried through oil pipe 2. The operation is repeated continuously in sequence.
A water circulation loop: the water storage tank 6 stores cold water, and realizes the flowing circulation of water through the power of the water pump and the transmission route of the water pipe.
The liquid flowing directions of the wire drawing oil circulation loop and the water circulation loop are opposite, so that the contact area and the contact time of water and the wire drawing oil are increased to the maximum extent, the heat in the wire drawing oil is brought quickly, and the cooling efficiency of the wire drawing oil is improved.
