[0044] Embodiment 1

[0045] like Figures 1 to 3As shown, the oil cleaning and filtering device for cold rolling of aluminum plate of the present application comprises a housing 100 and an upper cover 110, wherein the housing 100 and the upper cover 110 are detachably connected, the upper part of the upper cover 110 is connected to an oil inlet pipe 120, and the lower part of the housing 100 is connected to an oil drain pipe 130, and the upper cover 110 is connected to the oil inlet pipe 120 at a fixed connection to a small end face of an oil inlet hopper 140, and the large end face of the oil inlet hopper 140 is detachably connected to a filter bag 150;

[0052] The working process of the oil cleaning and filtering device in the cold rolling of aluminum plate in the embodiment of the present application is as follows:

[0053] The airbag 200 can adjust its own size according to the specifications and amount of oil. When the specifications of the processed aluminum plates are different, the specifications and amount of oil used are also different. At this time, the air pump delivers gas into the airbag 200 through the air intake pipe 210. The airbag 200 first expands and contracts axially and then expands and contracts radially.

[0054] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0055] The invention solves the technical problem that the existing equipment cannot adjust its own size according to the specifications and amount of oil, thereby reducing the filtering effect; and realizes the technical effect that the oil cleaning and filtering device can adjust its own size according to the specifications and amount of oil, thereby improving the filtering effect.

[0056] Embodiment 2

[0057] The following problems were found during the test of the above embodiment: Although the above embodiment can adjust its own size according to the specifications and amount of oil, thereby improving the filtering effect; after the filtration is completed, a large amount of oil still remains in the filter bag 150, which increases the subsequent flushing time and oil consumption.

[0058] In response to the above problems, Figures 4 to 5 As shown, this embodiment adds an external bag 300 and a bottom bag 310 on the basis of the above embodiment;

[0059] The external bag 300 is a rubber bag fixedly connected to the outer wall of the air bag 200, with the top thereof being in the same plane as the top of the air bag 200 and the bottom thereof being located 1 / 3 above the bottom of the air bag 200; the top of the external bag 300 is connected to a vent pipe 320 connected to an air pump, so as to squeeze and remove the residual oil on the inner wall of the filter bag 150;

[0060] The bottom bag 310 is a rubber bag fixedly connected to the outer bottom of the air bag 200, and the top is fixedly connected to the bottom of the outer bag 300; it plays the role of squeezing and removing the residual oil at the bottom of the filter bag 150;

Gas can only enter the bottom bag 310 from the outer bag 300, and plays the role of exhausting gas when the gas inside the outer bag 300 exceeds the set value of the exhaust valve 330.

[0062] A bottom exhaust valve 340 is fixedly connected below the bottom bag 310. The bottom exhaust valve 340 is a one-way valve. Gas can only be discharged through the bottom exhaust valve 340. When the gas inside the bottom bag 310 exceeds the set value of the bottom exhaust valve 340, the gas is discharged.

[0063] The outer bag 300 and the bottom bag 310 are both fixed with an elastic rope 350, which extends when the outer bag 300 and the bottom bag 310 are inflated, and drives the outer bag 300 and the bottom bag 310 to retract to their original positions when the ventilation tube 320 is not inflated, thereby driving the outer bag 300 and the bottom bag 310 to empty their internal gas and reset.

[0064] Preferably, the bottom exhaust valve 340 is an exhaust valve. When the amount of gas inside the bottom bag 310 reaches a set value of the bottom exhaust valve 340, the bottom exhaust valve 340 opens and exhausts all the gas in the outer bag 300 and the bottom bag 310 and then resets.

[0065] Preferably, the airbag 200, the outer bag 300 and the bottom bag 310 are all made of oil-resistant rubber.

[0068] When the airbag 200 has completed filtering the oil passing through the filter bag 150, the air pump inflates the outer bag 300 through the vent pipe 320 and drives the elastic rope 350 to stretch (the amount of gas during inflation is quantitative). When the outer bag 300 hits the filter bag 150, the air pressure in the outer bag 300 exceeds the set value of the exhaust valve 330, and the gas is discharged into the bottom bag 310 through the exhaust valve 330. When the bottom bag 310 hits the filter bag 150, the air pressure in the bottom bag 310 exceeds the set value of the bottom exhaust valve 330. 340 set value; then the gas in the outer bag 300 and the bottom bag 310 is discharged through the bottom exhaust valve 340; at the same time, since the gas no longer enters the outer bag 300 through the ventilation pipe 320, the elastic rope 350 gradually retracts and drives the outer bag 300 and the bottom bag 310 to retract, so the bottom exhaust valve 340 will exhaust all the gas when exhausting; the technical effect of further reducing the residual oil in the filter bag 150 after the filtration is completed and reducing the subsequent flushing time and oil consumption is achieved.

[0069] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0073] In response to the above problems, Figures 6 to 8 As shown, the external bag 300 is composed of a plurality of unit bags 400, and the unit bags 400 are annular bags that evenly divide the external bag 300 into a plurality of sections laterally. The connection between the unit bags 400 is fixedly connected with an exhaust valve 330 and the inside is fixedly connected with an elastic rope 350; the upper end of the bag body of the unit bag 400 is fixed at the middle position of the bag body of the previous unit bag 400, and when the bag body of the upper unit bag 400 expands, the bag body of the lower unit bag 400 is pulled to tilt upward.

[0074] Preferably, the number of the unit capsules 400 is four.
