[0024] When in use, the used cutting fluid flows downward along the feed pipe 2 to the inside of the housing 1, and the cutting fluid flows downward along the housing 1 to the sieve plate 32. After being filtered by the sieve plate 32, the cutting fluid continues to flow downward, and the solid impurities in the cutting fluid slide downward along the sieve plate 32 to the inside of the collecting device 33. The filtered cutting fluid flows downward to the inside of the storage device 5, and the cutting fluid is temporarily stored in the storage device 5.

[0025] When in use, the cutting fluid is filtered by setting up a filtering device 3 to separate the cutting fluid and solid impurities, and the filtered solid impurities are collected by a collecting device 33. The filtered cutting fluid is stored inside the storage device 5. The cutting fluid can be returned to the cold rolling mill through the storage device 5 for recycling to avoid waste.

[0026] The collecting device 33 includes a sliding bin 331, the outer side of the sliding bin 331 is slidably connected to the outer side of the fixed plate 31, a filter hole 332 is opened in the wall of the sliding bin 331, the top of the sliding bin 331 is fixedly connected to a support plate 333, and the bottom of the support plate 333 is slidably connected to the top of the fixed plate 31. When in use, solid impurities slide down along the sieve plate 32 into the sliding bin 331, and the cutting fluid remaining in the solid impurities is filtered through the filter hole 332 and continues to flow downward, and the solid impurities are collected by the collecting device 33, which is convenient for subsequent staff to handle the solid impurities.

[0027] The detachable device 4 includes a straight plate 41, the outer side of the straight plate 41 is slidably connected to the outer side of the shell 1, a material collection window 42 is opened in the wall of the shell 1, the outer side of the straight plate 41 is fixedly connected to a sliding plate 43, the outer side of the sliding plate 43 is slidably connected to the inner side of the material collection window 42, and the outer side of the sliding plate 43 is slidably connected to the inner side of the shell 1. During use, when the device stops being used, if there are many solid impurities in the collecting device 33, the straight plate 41 and the sliding plate 43 can be removed, and the straight plate 41 releases the material collection window 42. At this time, the collecting device 33 can be taken out through the material collection window 42, and the worker pours out the solid impurities in the collecting device 33, and then puts the collecting device 33 back to the fixed plate 31, and then installs the straight plate 41 back to the outer side of the shell 1.

The end of the discharge pipe 52 away from the storage bin 51 passes through the shell 1 and extends to the outside of the shell 1. When in use, the filtered cutting fluid flows downward to the inside of the storage bin 51. When the cold rolling mill is running, the cold rolling mill drives the cutting fluid to flow through the discharge pipe 52. The cutting fluid flows along the discharge pipe 52 to the inside of the cold rolling mill and is reused by the cold rolling mill. By setting up the storage device 5, the filtered cutting fluid is sent back to the cold rolling mill again, so that the cutting fluid can be recycled, avoiding waste of cutting fluid, saving resources, and reducing the pollution caused by waste cutting fluid to the environment.

The baffle 54 contacts the guide plate 53, and the guide plate 53 and the baffle 54 block the storage bin 51. The guide plate 53 and the baffle 54 cooperate with each other to prevent the cutting fluid inside the storage bin 51 from overflowing, and to avoid contamination of the filtered cutting fluid.

[0030] Working principle:

[0031] When in use, the cutting waste fluid flows downward along the feed pipe 2 to the inside of the outer shell 1, and the cutting fluid flows along the outer shell 1 to the sieve plate 32. The sieve plate 32 filters the cutting fluid, and the filtered cutting fluid continues to flow downward. The solid impurities in the cutting fluid slide down along the sieve plate 32 to the inside of the sliding bin 331. The cutting fluid remaining in the solid impurities continues to flow downward after being filtered through the filter hole 332. The filtered cutting fluid flows downward to the inside of the storage bin 51, and the cold rolling mill drives the cutting fluid to flow through the discharge pipe 52. The cutting fluid flows along the discharge pipe 52 to the inside of the cold rolling mill and is recycled by the cold rolling mill. When there are many solid impurities in the collecting device 33, the straight plate 41 can be removed, and the collecting device 33 can be taken out through the material taking window 42 to pour out the solid impurities in the collecting device 33.
