Coarse and fine double-layer external filtering equipment for cutting fluid of metal cutting machine tool

Abstract

The invention discloses coarse and fine double-layer external filtering equipment for cutting fluid of a metal cutting machine tool. The machine tool structurally comprises a water tank, a water pump,an electric control box, a motor, a filtering tank, an injection port, a filtering plate, a shielding plate and a filter residue collecting tank, wherein the water pump is fixedly mounted at the topof the water tank in an embedded mode. According to the equipment, a contact plate performs downward extrusion, then telescopic hoses contract and extend to generate certain air pressure, rotating shaft plates drive unidirectional opening and closing plates to rotate through extrusion force of the air pressure, and the air pressure is sprayed out through nozzles at the moment, so that the oxygen content of the water-based cutting fluid in the filtering tank is increased, and large-quantity propagation and proliferation of anaerobic bacteria are reduced; and dredging rods are inserted into filtering holes of the filtering plate at an inclined angle and move along with the conveying of the filtering plate, so that steering shafts drive the dredging rods to rotate, then adjusting rods contract in fixed pipe sleeves, the dredging rods move out of the filtering holes of the filtering plate, and the effect of filtering solid impurities such as abrasive particles and cuttings is improved through continuous stretch-in and move-out.

Description

technical field [0001] The invention relates to the field of metal cutting machine tools, and more specifically, relates to a rough and fine double-layer external filter device for cutting fluid of metal cutting machine tools. Background technique [0002] Water-based cutting fluid is represented by emulsion, in which fine oil droplets are highly dispersed in water, which can lubricate the tool, improve cutting ability and effectively prevent the corrosion of the workpiece and the guide rail of the cutting machine tool. The cutting fluid is filtered so that the water-based cutting fluid can be recycled. However, after the emulsion passes through the processing part, in addition to solid impurities such as abrasive grains and cutting, the insoluble oxygen in the emulsion is consumed, resulting in the lack of oxygen in the water body. At this time, anaerobic Bacteria will multiply and proliferate in large numbers, and a large number of bacteria will grow, causing the emulsion ...

[0002] Water-based cutting fluid is represented by emulsion, in which fine oil droplets are highly dispersed in water, which can lubricate the tool, improve the cutting ability and effectively prevent the corrosion of the workpiece and the guide rail of the cutting machine tool. The cutting fluid is filtered so that the water-based cutting fluid can be recycled. However, after the emulsion passes through the processing part, in addition to solid impurities such as abrasive grains and cutting, the insoluble oxygen in the emulsion is consumed, resulting in a lack of oxygen in the water body. At this time, anaerobic Bacteria will multiply and proliferate in large numbers, and a large number of bacteria will grow, causing the emulsion to turn black and smelly, and the effect of cooling and lubrication will drop rapidly. The effect of filtering solid impurities such as particles and chips
