Background
In the existing cable production process, the process generally comprises the working procedures of wire drawing, toughening, stranding, insulation, crosslinking, disc matching, extrusion molding, cabling and the like, wherein the wire drawing refers to a pressure processing method for reducing the section and increasing the length of a wire blank by plastic deformation under the action of a certain tensile force through a die hole. In the process of drawing copper wires and the like, a large amount of metal chips are generated by friction between the copper wires and a drawing die and enter a drawing liquid, wherein small metal chips are suspended in the liquid and enter the drawing die again along with the continuous circular flow of the drawing liquid, so that the metal chips at the opening of the drawing die are accumulated, the drawing is broken, and meanwhile, the metal chips can block a drawing liquid circulating pipeline and damage equipment such as a drawing liquid supply pump; the larger metal chips sink to the bottom of the bath and also deposit on the wire-drawing die, guide wheels, damaging the steel wires, aluminum wires, etc., and must therefore be filtered from the drawing oil.
At present, the commonly used filtering method of various domestic wiredrawing manufacturers is non-woven fabric filtering or filter cotton filtering (such as CN207221485U and CN 209451463U), after the wiredrawing liquid is discharged from a wiredrawing machine, the wiredrawing liquid firstly flows through the non-woven fabric or filter cotton for filtering and then enters a wiredrawing liquid pool, and then the wiredrawing liquid is pumped into the wiredrawing machine by a supply pump, so that the filtering of the wiredrawing liquid is realized. However, the non-woven fabric electrode or the filter cotton is easily blocked by metal chips, so that the filtering efficiency of the wire drawing liquid is low, and the normal operation of the wire drawing process is seriously influenced.

However, in the actual use process, the following technical problems still exist:
firstly, because the wire drawing liquid is rich in copper mud, the wire drawing liquid splashes to an insulating support provided with two electrode rods when the filtering device works, so that the two electrode rods are conducted on the support, an error signal is given, and when the liquid level falls to a normal position, the paper feeding mechanism continues to feed paper. If the filter paper is not found in time and is manually shut down, the filter paper is continuously conveyed, so that the filter paper is seriously wasted, and meanwhile, the filter device cannot normally work, so that the filtering efficiency and the filtering quality of the wire drawing liquid are greatly influenced;
secondly, the existing wire drawing liquid filtering device is low in working efficiency and poor in filtering quality, actual production requirements cannot be met, and finally the service life of the wire drawing liquid is short.
