Description

{Coolant tank filter clogging device}

The present invention relates to an eye blocking device of a coolant tank filter. And more particularly, to a cockpit filter filter for preventing clogging of a filter due to chips generated during processing of a workpiece.

Generally, a coolant used in a machine tool is continuously sprayed and circulated by a coolant pump of an external coolant storage tank attached to the side of the machine tool, and is used for cutting, drilling, boring, It serves to prevent heat and tool wear due to friction between materials and to prevent material changes due to heat. Such coolants are classified into individual methods and concentrated methods.

Coolant is a cutting oil that is used in machining lines for improving cooling, machinability, tool life, and chip flow. There are water-soluble cutting oil and water-insoluble cutting oil. In recent years, The use of cutting oil causes factors such as fire occurrence and environmental deterioration. However, the use of cutting oil has been promoted to be water-soluble. However, it is still not enough and a water-soluble coolant has been developed and will be described in detail with reference to Patent Document 1 .

(Patent Document 1) relates to a coolant grinding apparatus, which comprises a primary tank through which coolant and chips flow through a flow path so as to separate coolant and chips recovered after cutting, And a clean tank for collecting the re-filtered coolant in the secondary tank. The coolant and coolant introduced from the inlet are separated from the coolant and the chip, And a chute conveyor made of mesh net on the upper part of the car conveyor.

However, when the coolant and the fine chips pass through the primary tank, the secondary tank, and the chip-chip conveyor, when the filter is clogged by the chip, the coolant flow is not smooth, The frequency of the filter cleaning cycle is frequently increased, resulting in inconvenience to the user.
