A guide wheel for guiding the traction rope is arranged at the bottom of the lower fixing plate.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. By starting the drive motor, the output shaft of the drive motor drives the switching rod to rotate. The switching rod drives the switching disc to rotate, switching another filter bag between the liquid inlet pipe and the liquid outlet pipe to maintain normal filtration. At the same time, the used filter bag rotates to the position of the processing mechanism, and the processing mechanism pre-treats the filter bag. The previously pre-treated filter bag is switched to the backwashing component to discharge the filter residue on the filter bag. After the pre-treatment is performed, the cleaning of the filter bag is more thorough.

[0044] 2. The cleaning liquid is discharged through the nozzle to the through groove of the switching disc to soak the filter bag inside the through groove, separating the engine oil from the filter bag. The cleaning liquid can be alcohol or gasoline. The organic solvent can dissolve in water and can effectively dissolve the engine oil, thus avoiding the difficult-to-clean situation caused by the viscosity of the engine oil itself.

[0045] 3. The winding disc drives the fixedly connected rotating disc to rotate through the support rod. The rotating disc drives the eccentrically rotating rotating plate to pull the sliding plate to reciprocate up and down, so that the pushing plate is continuously pushed upward, pushing the cleaning liquid on the top of the pushing plate, making the cleaning liquid continuously pass through the filter bag, thereby improving the cleaning effect of the cleaning liquid on the engine oil.

[0046] 4. As the moving disc rises, the third spring provided on the isolation baffle contacts the lower fixed plate. When the moving disc continues to rise, the flow groove on the moving disc is exposed at this time. A large amount of water enters the inside of the rotating cylinder through the flow groove, pushing up the sealing plate inside the rotating cylinder. At this time, the water continuously flushes out through the flow holes on the outside of the rotating cylinder, thereby flushing the filter bag. As the sealing plate continuously rises, the contact surface of the flushing filter bag also continuously changes. In the early stage of flushing, the cleaning brush rotates and cleans the filter bag. At this time, the flushing can easily remove the filter substances on the filter bag.

[0047] 5. The electromagnet ring drives the annular brush plate to rotate through the limiting rod, and the rotating cylinder pushes the filter bag to continuously pass through the annular brush plate. Then the annular brush plate continuously rotates and cleans the outside of the filter bag, cooperating with the cleaning brush on the outside of the rotating cylinder for cleaning. By cleaning the upper and lower sides of the filter bag, the cleaning effect is improved. When the cleaning is completed, the electromagnet ring is powered off, and the water inside the lower cleaning cylinder flows back and is discharged. At this time, the moving disc descends and resets under the action of gravity. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0064] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0065] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0066] As Figures 1 to 14 shown, the precision strip rolling oil filtration system includes the following embodiments:

[0067] Embodiment 1: As Figure 1 , Figure 2 , Figure 3 and Figure 14 shown, it includes a filter cartridge 1, and further includes:

[0068] A switching disk 2 rotatably connected inside the filter cartridge 1. A plurality of through slots are provided inside the switching disk 2, and filter bags 200 for filtration are fixedly connected inside each of the plurality of through slots. An upper fixing plate 201 is provided above the switching disk 2, and a lower fixing plate 202 is provided below the switching disk 2. Both the upper fixing plate 201 and the lower fixing plate 202 are fixedly connected to the inner wall of the filter cartridge 1;

[0069] The switching rod 203 fixedly connected to the switching disk 2 passes through the lower fixing plate 202 and the bottom of the filter cylinder 1 in sequence and is rotatably connected to the lower fixing plate 202 and the filter cylinder 1. A driving motor 204 is fixedly connected to the bottom of the filter cylinder 1, and the output shaft of the driving motor 204 is fixedly connected to the switching rod 203 for driving the switching disk 2 to switch the filter bag 200 through the rotation of the switching rod 203;

[0070] A cleaning mechanism disposed inside the filter cylinder 1 is used to clean the used filter bag 200. The cleaning mechanism includes a processing mechanism 4 and a backwashing component. The filter bag 200 is pretreated by the processing mechanism 4, and then the pretreated filter bag 200 is backwashed and cleaned by the backwashing component;

[0071] A liquid inlet pipe 301 is fixedly connected to the top of the upper fixing plate 201. The liquid inlet pipe 301 passes through the outside of the filter cylinder 1 for inputting engine oil. A liquid outlet pipe 302 is fixedly connected to the bottom of the lower fixing plate 202. The liquid outlet pipe 302 extends to the outside of the filter cylinder 1 for outputting the filtered engine oil. The liquid inlet pipe 301, the liquid outlet pipe 302 and one of the filter bags 200 form a filtering channel.

[0072] Specifically, during the strip rolling process, engine oil is used. After the engine oil is used, it will carry waste residues and cannot be directly used. It is often filtered through a filtering device and then used continuously. The existing filtering is carried out through a filter bag or other filter meshes. After the filtering device is used, a large amount of filter residues will remain inside the filtering equipment. At this time, the equipment often needs to be paused and then cleaned. First, it will affect the normal operation of filtering, and it is too cumbersome to disassemble the equipment. Therefore, in the present invention, when the engine oil to be filtered is introduced through the liquid inlet pipe 301, it passes through the through groove opened on the switching disk 2. By arranging the filter bag 200 inside the through groove, after passing through the filter bag 200, it is then discharged through the liquid outlet pipe 302, so as to achieve the filtering of the engine oil. After the filter bag 200 has filtered a large amount of filter residues after long-term use, the driving motor 204 is started at this time. The output shaft of the driving motor 204 drives the switching rod 203 to rotate, and the switching rod 203 drives the switching disk 2 to rotate, switching another filter bag 200 between the liquid inlet pipe 301 and the liquid outlet pipe 302 to maintain normal filtering. At the same time, the used filter bag 200 is rotated to the position of the processing mechanism 4, and the filter bag 200 is pretreated by the processing mechanism 4, while the previously pretreated filter bag 200 is switched to the backwashing component to discharge the filter residues on the filter bag 200. After the pretreatment is performed, the cleaning of the filter bag 200 is more thorough.

[0073] Embodiment 2: As Figure 4 、 Figure 5 and Figure 6 shown, the processing mechanism 4 includes:

[0074] The upper soaking cylinder 401 is fixedly connected to the top of the upper fixing plate 201, and an infusion member is arranged inside the upper soaking cylinder 401 for discharging the cleaning liquid into the through groove;

[0075] The lower soaking cylinder 402 is fixedly connected to the bottom of the lower fixing plate 202, and the lower soaking cylinder 402 is arranged corresponding to the upper soaking cylinder 401. An impact member is arranged inside the lower soaking cylinder 402, and the impact member is used to repeatedly push the cleaning liquid through the filter bag 200.

[0076] The infusion member includes:

[0077] The upper baffle 4011 arranged inside the upper soaking cylinder 401 is slidably connected to the inside of the upper soaking cylinder 401;

[0078] A plurality of sliding rods 4012 fixedly connected to the top of the upper baffle 4011. The plurality of sliding rods 4012 all penetrate through the upper soaking cylinder 401 and are slidably connected to the upper soaking cylinder 401. A first spring 4015 is sleeved outside each of the plurality of sliding rods 4012, and two ends of the first spring 4015 are respectively fixedly connected to the sliding rod 4012 and the upper soaking cylinder 401;

[0079] The nozzle 4013 for discharging liquid is fixedly connected to the inside of the upper baffle 4011. A liquid spraying pipe 4014 is fixedly connected to the top of the upper soaking cylinder 401. One end of the liquid spraying pipe 4014 extends into the upper soaking cylinder 401 and is communicated with the nozzle 4013, and the other end of the liquid spraying pipe 4014 extends outside the filter cylinder 1 and is communicated with an external cleaning liquid pipeline.

[0080] During specific implementation, when the filter bag 200 to be pretreated is switched between the upper soaking cylinder 401 and the lower soaking cylinder 402, by opening the control valve arranged outside the liquid spraying pipe 4014, the cleaning liquid is discharged through the nozzle 4013 to the through groove of the switching disk 2, the filter bag 200 inside the through groove is soaked, the machine oil is separated from the filter bag 200, and the cleaning liquid can be alcohol or gasoline. The organic solvent can dissolve in water and can effectively dissolve the machine oil, thereby avoiding the difficult-to-clean situation caused by the viscosity of the machine oil itself.

[0081] In this embodiment: As Figure 6 and Figure 7 shown, the impact member includes:

[0082] The pushing plate 4021 arranged inside the lower soaking cylinder 402 is slidably connected to the inner wall of the lower soaking cylinder 402;

[0083] The sliding plate 4022 fixedly connected to the bottom of the push plate 4021 penetrates through the lower soaking cylinder 402 and is slidably connected to the lower soaking cylinder 402. One end of the sliding plate 4022 away from the push plate 4021 is rotatably connected to a rotating plate 4023;

[0084] The rotating disk 4026 is arranged below the lower soaking cylinder 402. The rotating disk 4026 is rotatably connected to the rotating plate 4023, and the rotation connection point between the rotating disk 4026 and the rotating plate 4023 is eccentrically arranged;

[0085] The winding disk 4025 is arranged on one side of the rotating disk 4026. A rotating rod is fixedly connected between the winding disk 4025 and the rotating disk 4026. A support plate 4024 is fixedly connected to the bottom of the lower soaking cylinder 402. The rotating rod penetrates through the support plate 4024 and is rotatably connected to the support plate 4024. The rotating rod and the support plate 4024 are connected by a torsion spring. A driving member is arranged outside the winding disk 4025, and the driving member is in transmission connection with the winding disk 4025 for driving the rotating disk 4026 to rotate.

[0086] During specific implementation, when the winding disk 4025 is driven to rotate by the driving member, the winding disk 4025 drives the fixedly connected rotating disk 4026 to rotate through the support rod. The rotating disk 4026 drives the eccentrically rotating rotating plate 4023 to pull the sliding plate 4022 to reciprocate up and down, so that the push plate 4021 is continuously pushed upward, and the cleaning liquid on the top of the push plate 4021 is pushed, so that the cleaning liquid continuously passes through the filter bag 200, thereby improving the cleaning effect of the cleaning liquid on the engine oil.

[0087] Embodiment Three: As Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, the backwashing assembly includes:

[0088] The upper cleaning cylinder 501 fixedly connected to the top of the upper fixing plate 201. A rotating member for cleaning the upper part of the filter bag 200 is arranged inside the upper cleaning cylinder 501;

[0089] The lower cleaning cylinder 502 fixedly connected to the bottom of the lower fixing plate 202. A rising member for rising into the through groove is arranged inside the lower cleaning cylinder 502. The lower cleaning cylinder 502 is arranged below the upper cleaning cylinder 501. When water passes through the lower cleaning cylinder 502, the rising member is pushed into the through groove of the switching disk 2, thereby cleaning the filter bag 200.

[0090] During specific implementation, when the filter bag 200 soaked in the cleaning liquid rotates to the backwashing component, clean water is introduced into one end of the lower cleaning cylinder 502 downward. The clean water pushes the lifting member, causing the lifting member to move into the through groove and jack the filter bag 200 upward and into the upper cleaning cylinder 501. And the clean water is discharged through the upper cleaning cylinder 501, and the filter residue is carried away during the discharging process, so as to clean the filter bag 200 without disassembling the equipment.

[0091] In this embodiment, as Figure 8 、 Figure 9 、 Figure 11 and Figure 12 shown, the lifting member includes:

[0092] A moving disk 5021 disposed inside the lower cleaning cylinder 502, and a circulation groove is formed at the bottom of the moving disk 5021;

[0093] A rotating cylinder 5022 rotatably connected to the top of the moving disk 5021. A plurality of circulation holes are formed on the outer side of the rotating cylinder 5022, and a plurality of cleaning brushes 5024 for cleaning the filter bag 200 are fixedly connected to the outer side of the lower cleaning cylinder 502;

[0094] An isolation baffle 504 disposed at the bottom of the moving disk 5021. A plurality of mounting rods 5041 are fixedly connected to the top of the isolation baffle 504. The plurality of mounting rods 5041 all penetrate the moving disk 5021 and are slidably connected to the moving disk 5021. And a third spring 5042 is sleeved on the outer side of each of the plurality of mounting rods 5041. The two ends of the third spring 5042 are respectively fixedly connected to the mounting rod 5041 and the moving disk 5021, and are used to push the isolation baffle 504 to close the circulation groove;

[0095] An external gear ring 5025 fixedly connected to the outer side of the rotating cylinder 5022. A connecting member is disposed inside the lower cleaning cylinder 502, and when the water pushes the moving disk 5021 to rise, the external gear ring 5025 is driven to rotate through the connecting member;

[0096] A sealing plate 5027 disposed inside the rotating cylinder 5022. A fixing rod 5028 is fixedly connected to the inside of the rotating cylinder 5022. The fixing rod 5028 penetrates the sealing plate 5027 and is slidably connected to the sealing plate 5027. And a second spring 5029 is sleeved on the outer side of the fixing rod 5028;

[0097] A magnetic ring 5026, and the magnetic ring 5026 is fixedly connected to the top of the rotating cylinder 5022.

[0098] During specific implementation, when water is introduced into the interior of the lower cleaning cylinder 502, it pushes the moving disk 5021 inside the lower cleaning cylinder 502 to rise. Since the isolation baffle 504 at the bottom of the moving disk 5021 seals the flow groove inside the moving disk 5021, the water can thus push the moving disk 5021 to rise, causing the rotating cylinder 5022 to insert into the through groove. The cleaning brush 5024 provided on the outer side of the rotating cylinder 5022 continuously contacts the filter bag 200, thereby cleaning the filter bag 200. And during the rising process, the outer gear ring 5025 is driven to rotate through the connecting member, and the outer gear ring 5025 drives the rotating cylinder 5022 to rotate, thereby further improving the cleaning effect on the filter bag 200. It should be noted that cleaning brushes are also provided at the top of the rotating cylinder 5022. And as the moving disk 5021 rises, the third spring 5042 provided on the isolation baffle 504 contacts the lower fixing plate 202. When the moving disk 5021 continues to rise, the flow groove on the moving disk 5021 is exposed at this time. A large amount of water then enters the interior of the rotating cylinder 5022 through the flow groove, pushing up the sealing plate 5027 inside the rotating cylinder 5022. At this time, the water continuously rushes out through the flow holes on the outer side of the rotating cylinder 5022, thereby flushing the filter bag 200. As the sealing plate 5027 continuously rises, the contact surface of the flushing filter bag 200 also continuously changes. In the early stage of flushing, the cleaning brush 5024 rotates and cleans the filter bag 200, and at this time, the flushing can easily remove the filter substances on the filter bag 200.

[0099] In this embodiment, as Figure 11 and Figure 12 shown, the connecting member includes:

[0100] A plurality of sliding rods 5031 fixedly connected to the interior of the lower cleaning cylinder 502, and spiral grooves are provided on the outer sides of the plurality of sliding rods 5031;

[0101] A transmission gear 5032 sleeved on the outer side of the sliding rod 5031. A rotating ring 5033 is connected to the interior of the transmission gear 5032 through a one-way bearing. A slider is fixedly connected to the interior of the rotating ring 5033, and the slider extends into the spiral groove inside the sliding rod 5031. The transmission gear 5032 is rotatably connected to the moving disk 5021. When the moving disk 5021 pushes the transmission gear 5032 to rise, the transmission gear 5032 rotates through the rotating ring 5033.

[0102] During specific implementation, when the moving disk 5021 rises, the driving gear 5032 rotating on the moving disk 5021 also continuously rises. At this time, the rotating ring 5033 connected to the inside of the driving gear 5032 through a one-way bearing slides on the outside of the sliding rod 5031. The slider arranged inside the rotating ring 5033 rotates through the action of the spiral groove, thereby driving the driving gear 5032 to rotate. The driving gear 5032 drives the external gear ring 5025 to rotate, and the external gear ring 5025 drives the rotating cylinder 5022 to rotate, so as to achieve the upward rotation of the cleaning brush 5024 on the outside of the rotating cylinder 5022 relative to the filter bag 200.

[0103] In this embodiment: As Figure 13 shown, the rotating member includes:

[0104] An annular brush plate 5011 rotatably connected inside the upper cleaning cylinder 501, and a brush is arranged inside the annular brush plate 5011;

[0105] A plurality of limiting rods 5013 fixedly connected to the top of the annular brush plate 5011, and a rotating ring 5014 is fixedly connected to the tops of the plurality of limiting rods 5013. The rotating ring 5014 is rotatably connected to the upper cleaning cylinder 501;

[0106] An electromagnet ring 5012, and a plurality of limiting rods 5013 penetrate through the electromagnet ring 5012 and are slidably connected to the electromagnet ring 5012. After the rotating cylinder 5022 rises, the electromagnet ring 5012 is magnetically attracted by the magnetic ring 5026 after being energized, and drives the electromagnet ring 5012 to rotate together.

[0107] During specific implementation, when the rotating cylinder 5022 continuously pushes the filter bag 200 to rise, at this time the magnetic ring 5026 passes through the electromagnet ring 5012, and the electromagnet ring 5012 is energized and magnetically attracted to the magnetic ring 5026, and rises and moves together with the magnetic ring 5026. During the movement, the magnetic ring 5026 rotates with the rotating cylinder 5022, thereby driving the electromagnet ring 5012 to rotate. The radius of the magnetic ring 5026 is smaller than that of the electromagnet ring 5012, and the electromagnet ring 5012 does not contact the filter bag 200. The electromagnet ring 5012 drives the annular brush plate 5011 to rotate through the limiting rods 5013, and the rotating cylinder 5022 continuously pushes the filter bag 200 through the annular brush plate 5011. Then the annular brush plate 5011 continuously rotates and cleans the outside of the filter bag 200, and cooperates with the cleaning brush 5024 on the outside of the rotating cylinder 5022 for cleaning. By cleaning the upper and lower sides of the filter bag 200, the cleaning effect is improved. After the cleaning is completed, the electromagnet ring 5012 is powered off, and the water inside the lower cleaning cylinder 502 flows back and is discharged. At this time, the moving disk 5021 is reset by gravity.

[0108] Embodiment 4: As Figure 4 and Figure 6As shown, the driving member includes a towing rope 4027. The towing rope 4027 is wound and connected to the outside of the winding disc 4025. The other end of the towing rope 4027 passes through the lower cleaning cylinder 502 and is fixedly connected to the moving disc 5021. A guide wheel 4028 for guiding the towing rope 4027 is provided at the bottom of the lower fixing plate 202.

[0109] In this embodiment, when the moving disc 5021 rises, the winding disc 4025 can be driven to rotate through the towing rope 4027, so as to provide power for the impact member and implement synchronously with the recoil mechanism.
