Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling, in particular to a primary filtering device for cold rolled grease mixture. Background Art

[0002] Cold rolling uses hot-rolled steel coils as raw materials, and then cold rolling is carried out after pickling to remove the oxide scale. The finished product is hardened coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the hardened coils increase, and the toughness and plasticity index decrease, so the stamping performance will deteriorate and it can only be used for parts with simple deformation. At the same time, a large amount of sewage mixture containing grease will be generated during the cold rolling process, so how to deal with it becomes a problem that must be solved.

[0003] The patent with the publication number of CN 219662938 U discloses an industrial waste grease recovery device, which includes a recovery tank, a support frame connected to the lower surface of the recovery tank, a top cover connected to the top of the recovery tank, a motor connected to the upper surface of the top cover, and a feed pipe arranged on one side of the motor. The device increases the adjustable two-way collection pipe arranged at the bottom of the recovery tank to avoid mixing the flushing water with the grease mixture during collection, so as to improve the purity of the waste gas grease collection, thereby effectively solving the problems and shortcomings of the existing device. However, the device has the problem that when filtering and collecting the grease mixture, the grease mixture is filtered by a filter plate, and the impurities left by the filtration will remain on the filter plate. Although the filter plate is detachable, it is difficult to use a tool to clean the impurities on the filter plate after opening the top cover. If the filter plate is directly removed for cleaning, the process may be misoperated such as offset, and the filtered impurities may easily fall into the recovery pipe and be difficult to clean out. Therefore, a primary filtering device for cold-rolled grease mixture is proposed to solve the problem that the existing grease mixture filtering device is difficult to quickly collect and clean the filtered impurities.
