High-efficiency coolant filter unit

Abstract

The invention provides a high-efficiency coolant filter unit which comprises a filter box, filter screens, a circulating pipeline and a cooling layer, wherein the upper end of the filter box is provided with a filtrate inlet, and the lower end is provided with a filtrate outlet; the upper end and lower end of the filter box are respectively provided with a circulating liquid inlet and a circulating liquid outlet; the filter screens divide the inside of the filter box into a first filter chamber, a second filter chamber, a third filter chamber and a buffer chamber; the circulating pipeline comprises a main pipe and a branch pipe; the main pipe is connected with the circulating liquid outlet; the branch pipe is connected with the corresponding circulating liquid inlet; the main pipe and branch pipe are respectively provided with a valve; the cooling layer is arranged outside the side wall of the filter box; and the upper end and lower end of the cooling layer are respectively provided with a cooling water outlet and a cooling water inlet. The cooling layer can quickly lower the temperature of the grinding fluid. The circulating pipeline implements sufficiency of filtration. The filter screens are obliquely arranged at the scrap iron outlet on the lower side, thereby greatly facilitating the cleaning of the scrap iron.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a cooling liquid high-efficiency filter device. Background technique [0002] In the field of mechanical processing, it is often necessary to use a grinding machine to grind and shape the mechanical workpiece to be processed. When the grinding machine is processing metal objects, the grinding head of the grinding machine rubs against the processed object, rotates at a high speed, the surface heats up quickly, and the temperature is high. Grinding fluid is poured over the grinding head and the friction surface of the processed object to cool down and wash metal shavings. After the grinding fluid drips from the grinding head, it becomes a tail fluid, which is mixed with metal shavings. If the tail liquid is directly discharged, it will not only seriously pollute the environment, but also waste the grinding fluid. The current common method is t...

Problems solved by technology

When the iron filings between the filters accumulate too much, it is necessary to stop filtering to remove the iron filings, and there is no guarantee that the final filtered grinding fluid meets the standard

At present, most of the filtering devices adopt the natural cooling method for the grinding fluid, and the natural cooling speed is slow, and often the grinding fluid has not reached the recyclable temperature after the final filtration
