The invention discloses a cold rolling mill rolling oil filtration and sedimentation system and a processing method thereof.The cold rolling mill rolling oil filtration and sedimentation systemcomprises a filtration tank and a plurality of sedimentation tanks, wherein the filtration tank is connected to the sedimentation tanks through sewage pipelines; the sewage pipelinesare sequentially connected with a breaking valve, a diaphragm pump, and an oil inlet valve; the sedimentation tankscomprises a square tank bodyand a sludge discharge opening, wherein the square tank body and the sludge discharged opening are integrally connected; the side edges of square tank body and the sludge discharged opening are connected with oil discharge pipes through oil discharge valves; the upper part of the square tank body is connected to an overflow pipeline through an overflow opening; the lower part of the sludge discharge opening is connected to a sludge discharge pipelinethrough a sludge discharge valve, and a liquid level gauge is connected to the side edge of the sludge discharge opening. Compared with the prior art, the cold rolling mill rolling oil filtration and sedimentation system and theprocessing method thereof have the advantages that the structure is simple,by reasonably setting the number of sedimentation tanks, the requirements of cold rolling mill rolling oil filtration and sedimentationare met, and the efficiency of the filtration and sedimentation systemis effectively improved after preliminary filtration, sump oil discharging, secondary filtration, and sludge discharging.
Description
technical field [0001] The invention relates to the technical field of stainless steel production, in particular to a cold rolling mill rolling oil filtration precipitation system and a treatment method thereof. Background technique [0002] Rolling oil has the function of cooling and lubricating during the rolling process, washing away impurities. In order to save costs, general enterprises can continue to use the rolling oil after filtering; the impurities and oxide scales taken away by the rolling oil during the rolling process etc. are mixed in rolling oil, and these impurities can be discharged after being filtered; at present, the existing filtering equipment has a complicated structure and high price and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cold rolling mill rolling oil filtration sedimentation system and a treatment method thereof in view of the above-mentioned deficiencies in the prior...
