[0002] The filter can filter some high-concentration and high-urea liquids, such as liquids like engine oil. By installing a spin-on filter, the engine oil can be filtered, thereby ensuring that the engine oil recycling is more convenient. However, some existing spin-on filters still have some shortcomings when used, such as:

[0003] The oil filter elements of some existing spin-on filters isolate water to allow the oil to pass through and then collect the oil. Since the water is blocked outside, when the staff needs to replace and repair the filter, after opening the entire filter, water will automatically flow, causing sewage to drip onto the ground, which can easily pollute the environment and is inconvenient for the staff to centrally treat the sewage.

[0004] Therefore, we propose a spin-on filter to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a spin-on filter, comprising a shell 1, characterized in that: an upper clamping block 2 is threadedly connected to the upper surface of the shell 1, a lower clamping block 3 is threadedly connected to the lower outer surface of the shell 1, a center tube 4 is arranged inside the shell 1, and a threaded cover assembly 8 is threadedly connected to the upper surface of the center tube 4. Through the arrangement of the upper clamping block 2 and the lower clamping block 3, it is convenient for the staff to disassemble and assemble the shell 1, and then it is convenient for the staff to inspect and replace the interior of the entire device. At the same time, through the arrangement of the center tube 4, the entire device can only allow oil to pass through, and water cannot pass through, so that the entire device can achieve efficient oil-water separation, improve the filtering capacity of the entire device, and through the clamping position of the threaded cover assembly 8, the entire device can automatically squeeze and absorb water, so that after the entire device is disassembled, the dripping of sewage is reduced, thereby reducing the impact of sewage on the environment, and at the same time, during transportation, the immersion of the replaced filter element by sewage is reduced, so that the recycling and reprocessing of the filter element is more convenient.

[0024] The connection method between the shell 1 and the threaded cover assembly 8 is a snap-fit ​​connection. The lower surface of the threaded cover assembly 8 is fixedly connected with a connecting block 9 by bolts, and the upper surface of the threaded cover assembly 8 is snap-fitted with an inner sealing ring 13. Through the sealing of the inner sealing ring 13, the engine oil inside the entire device will not evaporate through the upper part of the shell 1, thereby reducing the waste of engine oil and the impact of engine oil on the air environment. At the same time, through the disassembly and assembly of the threaded cover assembly 8, the connecting block 9 can be moved, so that the entire device can automatically squeeze the moisture on the filter element, so that after the entire device is disassembled, the dripping of sewage is reduced, thereby reducing the impact of sewage on the environment. At the same time, during transportation, the immersion of the replaced filter element by sewage is reduced, making the recycling and reprocessing of the filter element more convenient.

[0025] The outer surface of the central tube 4 is snap-connected with a water filter assembly 401, the outer surface of the central tube 4 is snap-connected with a filter element sealing ring 402, the outer surface of the water filter assembly 403 is covered with an oil filter element 401, and the arrangement of the water filter assembly 401 prevents water from penetrating, and the arrangement of the filter element sealing ring 402 ensures the sealing of the central tube 4, thereby reducing leakage of the central tube 4 and ensuring that the filtered oil will not be mixed with sewage again, thereby ensuring the purity of the filtered oil, making it convenient for staff to reuse the filtered oil and improving the utilization rate of the oil.

[0026] The water filter component 403 is made of Teflon material, and the connection between the oil filter element 401 and the center tube 4 is a snap-fit ​​connection. The opening on the lower surface of the center tube 4 is in contact with the tightening spring 5. The water filter component 403 filters the oil so that the oil can pass through, but the water cannot, so that the entire device can effectively purify the oil. At the same time, through the setting of the tightening spring 5, it is convenient for the staff to push the tightening spring 5, so that the entire device can discharge the filtered objects and facilitate the collection of the staff.

[0027] The connection between the end of the tensioning spring 5 and the lower cover end 12 is a bolted connection, and the connection between the lower cover end 12 and the outer shell 1 is a threaded connection. The accommodating block 15 and the outer shell 1 form a sliding structure. The tensioning spring 5 is connected to the lower cover end 12, so that after the lower cover end 12 is removed, the tensioning spring 5 is also removed at the same time, thereby facilitating the maintenance of the entire device by the staff.

[0028] The connection between the connecting block 9 and the connecting gear 10 is a meshing connection, and the connection between the connecting gear 10 and the rotating rod 14 is a bolted fixed connection. The connecting block 9 limits the connecting gear 10, so that the connecting gear 10 cannot rotate with the deformation of the torsion spring in the rotating rod 14, so that the entire device can operate normally when it is not disassembled, so that the entire device can better filter the engine oil.

[0029] Adhesive 6 is filled between the lower cover end 12 and the central tube 4. The setting of adhesive 6 not only facilitates the lower cover end 12 to lift the central tube 4, but also plays a sealing role, so that the central tube 4 can perform filtering operations better, thereby reducing the occurrence of leakage in the central tube 4.

[0030] The outer surface of the rotating rod 14 is wound and fixedly connected with the connecting wire 11, and the connection between the end of the connecting wire 11 and the receiving block 15 is fixedly connected. The rotating rod 14 reels up the connecting wire 11, so that the receiving block 15 can move, so that the receiving block 15 can squeeze the engine oil, so that the excess engine oil can be discharged and collected in a centralized manner, thereby reducing the staff's disassembly of the entire device, reducing the drop of oil stains, and thus reducing damage to the environment.

[0031] The receiving block 15 and the outer shell 1 form a sliding structure, and the inner surface of the receiving block 15 fits with the outer surface of the oil filter element 401. The receiving block 15 fits with the outer surface of the oil filter element 401 so that excess oil on the oil filter element 401 can be squeezed out, so that the staff can collect the filtered oil for reuse, and at the same time, when the entire device is disassembled, there will be no oil dripping, reducing the pollution of the oil to the environment. At the same time, the oil can be recycled, so that during the transportation of the filter element, the oil will not contaminate the transportation equipment.

[0032] Working principle: When the spin-on filter is used, the oil mixture enters from the upper part of the whole device, and then passes through the water filter assembly 403. The water filter assembly 403 blocks the flow of water, while the oil can smoothly pass through the water filter assembly, so that the oil can be filtered by the oil filter element 401. The oil filtered by the oil filter element 401 enters the receiving block 15, which is convenient for the staff to collect and reuse the mechanism in the receiving block 15;

[0033] When the entire device needs to be disassembled, use professional tools to rotate the upper clamping block 2 and the lower clamping block 3 to separate the upper clamping block 2 and the lower clamping block 3 from the outer shell 1, and then remove the threaded cover assembly 8. At this time, the assembly sealing ring 7 is still engaged in the threaded cover assembly 8, and the threaded cover assembly 8 is moved upward, thereby driving the connecting block 9 to drive the connecting gear 10 to rotate, so that the connecting gear 10 drives the rotating rod 14 to rotate, and then the rotating rod 14 reels the connecting line 11. When the connecting block 9 is separated from the connecting gear 10, under the action of the torsion spring of the rotating rod 14 to restore the deformation, the rotating rod 14 continues to reel in the connecting line 11, so that the connecting line 11 pulls the receiving block 15 to move upward, and then the receiving block 15 squeezes the outer surface of the oil filter element 401, so that the excess oil can be squeezed out, reducing the damage to the environment caused by oil dripping.

[0034] Then remove the central tube 4, so that the oil filter element 401 and the water filter assembly 403 are taken out to facilitate maintenance by the staff. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
