An oil inlet switch valve 4 is provided on the oil inlet pipe 3, and the staff controls the opening and closing state of the oil inlet pipe 3 by operating the oil inlet switch valve 4.

[0026] The upper open end of the recovery tank 1 is processed with an inner edge on the inner side of the tank; the lower part of the sealing cover 5 is processed with a sealing cover 12 that matches the inner edge of the recovery tank 1. A rubber ring 13 is bonded to the lower part of the sealing cover 5, and the rubber ring 13 is sleeved outside the sealing cover 12. A lifting ear 101 is processed on one side of the upper open end of the recovery tank 1; a connecting plate 501 that matches the lifting ear 101 is processed on one side of the sealing cover 5. Based on the above content and the attached manual Figure 1 ~Attached Figure 3 It can be seen that the sealing cover 5 is buckled at the upper opening of the recovery tank 1, the sealing cover 12 cooperates with the inner edge of the upper end of the recovery tank 1, and the rubber ring 13 is between the sealing cover 5 and the recovery tank 1. The sealing cover 12 and the rubber ring 13 play a double sealing role for the sealing cover 5 and the recovery tank 1, ensuring the sealing effect of the sealing cover 5. The sealing cover 5 set at the upper opening of the recovery tank 1 has its connecting plate 501 inserted between the lifting ears 101, and the lifting ears 101 and the connecting plate 501 are connected through the fixing pin 11, so that the sealing cover 5 is fixed on the recovery tank 1. This design is simple to disassemble and assemble, and is convenient for later maintenance.

[0027] The stirring component includes a servo motor 9, a stirring blade 10, a rotating rod 14, a nut connecting sleeve 15, a threaded connecting rod 16, a rubber sheet 17, a support rod 18 and a scraper 19. The servo motor 9 is fixed on the top of the sealing cover 5 by bolts. The output end of the servo motor 9 passes through the center of the sealing cover 5, extends into the recovery tank 1, and is mechanically connected to one end of the rotating rod 14. The end of the rotating rod 14 away from the output end of the servo motor 9 is welded to one end of the nut connecting sleeve 15, and the rotating rod 14 forms a closed shield for the end of the nut connecting sleeve 15 connected to it. The internal thread of the nut connecting sleeve 15 is matched with a threaded connecting rod 16. The rubber sheet 17 is arranged at the end of the threaded connecting rod 16 located at the opening of the nut connecting sleeve 15, and one side of the rubber sheet 17 is in contact with the end of the threaded connecting rod 16; the support rod 18 is arranged on the side of the rubber sheet 17 away from the threaded connecting rod 16, and one end of the support rod 18 is in contact with one side of the rubber sheet 17; the threaded connecting rod 16, the rubber sheet 17 and the support rod 18 are fixed together by screws. The stirring blades 10 are arranged in a ring on the outer periphery of the support rod 18 and fixed to the support rod 18 by screws; the stirring blades 10 are provided with slots 1001 distributed at intervals; and a scraper 19 is fixed to the side of the stirring blades 10 away from the rubber plate 17 by bolts.

[0028] Combining the above contents with the attached Figure 2 It can be seen that the stirring component uses a servo motor 9 to drive the rotating rod 14 to rotate, the rotating rod 14 drives the nut connecting sleeve 15 to rotate, the nut connecting sleeve 15 drives the threaded connecting rod 16 to rotate, the threaded connecting rod 16 drives the support rod 18 to rotate, and then the support rod 18 drives the stirring plate 10 to rotate, so as to stir the hydraulic waste oil collected in the recovery tank 1 and accelerate the separation of sediment. During the stirring process, the waste oil flows between the slots 1001, which improves the uniformity of the waste oil during stirring. The nut connecting sleeve 15 and the threaded connecting rod 16 in the stirring component adopt threaded matching, which can realize convenient assembly and disassembly operations, and facilitate the disassembly and cleaning of the support rod 18 and the stirring plate 10 connected to the threaded connecting rod 16 during later maintenance.

[0029] The filter component includes a primary filter plate 20 , a secondary filter plate 21 , a limit plate 22 , a lifting ring 23 and a sealing ring 24 .

[0030] Limiting plates 22 are welded on both sides of the primary filter plate 20; sliding grooves 102 that match the limiting plates 22 are opened on both sides of the inner wall of the recovery tank 1; the primary filter plate 20 is inserted and installed in the recovery tank 1 through the matching of the limiting plates 22 and the sliding grooves 102. The upper surface of the primary filter plate 20 contacts the lower surface of the scraper 19. A lifting ring 23 is welded on the upper side of the limiting plate 22.

[0031] A receiving ring 103 is machined inside the recovery tank 1. The receiving ring 103 is located below the sliding groove 102. A sealing ring 24 is provided on the outer sleeve of the secondary filter plate 21; the outer diameter of the sealing ring 24 is larger than the inner diameter of the receiving ring 103 and smaller than the inner diameter of the recovery tank 1; the secondary filter plate 21 is placed on the receiving ring 103 through the sealing ring 24 and installed in the recovery tank 1.

[0032] Both the primary filter plate 20 and the secondary filter plate 21 are provided with dense filter holes; the area of ​​the filter holes of the primary filter plate 20 is larger than the area of ​​the filter holes of the secondary filter plate 21, and the number of the filter holes of the primary filter plate 20 is smaller than the number of the filter holes of the secondary filter plate 21.

[0033] Combining the above contents with the attached Figure 3 ~Attached Figure 5 It can be seen that the filtering component uses a primary filter plate 20 and a secondary filter plate 21 to filter and recover the waste oil in the recovery tank 1, wherein the filtering grade of the secondary filter plate 21 is higher than that of the primary filter plate 20. The upper surface of the primary filter plate 20 contacts the lower surface of the scraper 19, so that the scraper 19 assists in scraping the waste oil through the primary filter plate 20, thereby improving the working efficiency. The secondary filter plate 21 adopts a simple placement structure and is installed in the recovery tank 1, which is convenient for disassembly and assembly, and is convenient for later maintenance; the sealing ring 24 can ensure the sealing between the secondary filter plate 21 and the bearing ring 103. The primary filter plate 20 can ensure the working stability of the primary filter plate 20 when the scraper 19 is scraping the oil on the upper surface of the primary filter plate 20 through the limiting cooperation between the limiting plate 22 and the sliding groove 102, thereby avoiding the position displacement of the primary filter plate 20. The function of the lifting ring 23 is to facilitate the staff to directly hold it by hand to drive the primary filter plate 20 and the limiting plate 22 to be disassembled and assembled in the recovery tank 1, which is convenient for later maintenance.

[0034] The static tank 6 is welded below the recovery tank 1. The static tank 6 is an inverted truncated cone structure interpenetrating with the recovery tank 1. The static tank 6 is used to store the hydraulic oil obtained after the waste oil is filtered. The bottom of the static tank 6 is provided with an oil drain pipe 7 interpenetrating with it. When the recovered hydraulic oil needs to be used, it is led out of the device through the oil drain pipe 7. The oil drain pipe 7 is provided with an oil drain switch valve 8, and the staff controls the opening and closing state of the oil drain pipe 7 by operating the oil drain switch valve 8.

[0035] The specific usage and function of this embodiment are as follows:

[0036] Before use, the recovery tank 1 is installed near the hydraulic device of the port equipment through existing support tools such as brackets, and the waste oil conduit on the hydraulic device is connected to the oil inlet pipe 3. When in use, the staff operates to open the oil inlet switch valve 4, and the waste oil overflowed from the hydraulic device is collected in the recovery tank 1 through the oil inlet pipe 3. At the same time, the servo motor 9 is started to drive the rotating rod 14 to rotate, and after transmission, the stirring blade 10 is driven to rotate. The stirring blade 10 rotates to stir the waste oil falling into the recovery tank 1. The stirred waste oil is filtered through the primary filter plate 20 and the secondary filter plate 21 in turn, and when the waste oil passes through the primary filter plate 20, the stirring blade 10 drives the rotating scraper 19 to assist in scraping the waste oil through the primary filter plate 20; finally, the new oil obtained after filtration will fall into the static tank 6 for storage. When it is needed, the staff operates to open the oil discharge switch valve 8, so that the new oil recovered in the static tank 6 is led out of the device through the oil discharge pipe 7. During later maintenance and cleaning, the staff can remove the sealing cover 5 and the stirring component from the recovery tank 1 by removing the fixing pin 11, and can remove it from the nut connecting sleeve 15 by twisting the threaded connecting rod 16, and then clean the stirring plate 10. After the sealing cover 5 and the stirring component are removed from the recovery tank 1, the staff can remove the primary filter plate 20 by the lifting ring 23, and then directly take out the secondary filter plate 21 manually to complete the cleaning operation of the two filter plates.

[0037] To sum up, compared with the prior art, the utility model effectively solves the problem that the hydraulic oil inside the hydraulic device of the port equipment overflows when it is in a long-term working state, causing on-site pollution and waste of resources due to the lack of waste oil recovery technology. The utility model also has the characteristics of easy disassembly, which is convenient for on-site maintenance and management.
