Description

Technical Field

[0001] This utility model relates to centrifugal oil purifiers, and more particularly to a sealed centrifugal oil purifier. Background Technology

[0002] Centrifugal oil purifiers, also known as centrifugal oil filters, use the principle of centrifugal separation. Based on the different specific gravities of oil and solid-liquid impurities, they use high-speed rotation to remove solid-liquid impurities from the oil, efficiently completing the purification process and enabling the oil to be recycled multiple times. They are suitable for the purification of lubricating oil, heavy diesel oil, and edible rapeseed oil, tea oil, peanut oil, etc. in power plants, ships, and large machinery.

[0003] The sealed design of the centrifugal oil purifier can effectively prevent oil mist and impurities from leaking out, reducing environmental pollution. At the same time, it can protect the equipment from the influence of external dust and impurities, thereby extending the service life of the equipment.

[0004] Existing closed-loop centrifugal oil purifiers are often single-unit designs, for example:

[0005] Publication No. CN214766209U discloses a sealed centrifugal oil purifier, comprising a body, two mounting rings symmetrically fixedly installed on both sides of the top of the body, an oil inlet hood fixedly installed in the middle of the top of the body, a power mechanism fixedly connected to one side of the body, a support mechanism fixedly connected to the bottom of the body, a sealing mechanism installed inside the oil inlet hood via fasteners, and an oil storage tank installed inside the body. This patented solution is a single-unit design, and the single-pass oil filtration capacity is limited by the oil filtration volume of the single-unit inner tank.

[0006] Publication No. CN220404905U discloses a sealed centrifugal oil purifier, comprising a sealed barrel, a centrifugal tank for centrifuging oil rotatably mounted inside the sealed barrel, several centrifugal valves uniformly fixedly connected to the bottom conical sidewall of the centrifugal tank, a centrifugal plug slidably mounted inside each centrifugal valve and positioned near the centrifugal tank, each centrifugal plug having several uniformly distributed flow holes, a spring slidably mounted inside the cavity of each centrifugal valve, a rotating cover rotatably mounted on the top of the sealed barrel, a sealing ring bonded to the bottom of the rotating cover and in contact with the sealed barrel, a rotating seat fixedly mounted on the top of the sealed barrel, a fixed seat adapted to the rotating cover fixedly connected to the rotating cover, a rotating screw rotatably mounted on the rotating seat, the rotating screw threadedly connected to a threaded seat, and the threaded seat engaging in a groove in the fixed seat. This patented solution is also a single-unit design, and the single-pass oil filtration capacity is limited by the oil filtration volume of the single-unit inner tank.

[0007] Single-unit centrifugal oil purifiers are limited by the oil filtration capacity of a single inner tank, resulting in limited economic efficiency. However, it is expensive for small-scale production enterprises to equip themselves with multiple centrifugal oil purifiers. This application aims to provide a double-unit sealed centrifugal oil purifier that doubles the oil filtration capacity in a single cycle while reducing the cost to less than two single-unit centrifugal oil purifiers. Utility Model Content

[0008] To address the shortcomings of the aforementioned technologies, this utility model provides a sealed centrifugal oil purifier.

[0009] To solve the above technical problems, the technical solution adopted by this utility model is: a sealed centrifugal oil purifier, including a first oil purifier outer liner and a second oil purifier outer liner arranged side by side. Abutment handles are formed on the outer surfaces of both the first and second oil purifier outer liners. Both the first and second oil purifier outer liners have an open top and a cavity. An oil inlet pipe communicating with the cavity is provided on the body of both the first and second oil purifier outer liners. An oil outlet component communicating with the cavity is provided at the bottom of both the first and second oil purifier outer liners. An upper cover is sealed to the open top of both the first and second oil purifier outer liners by an O-ring. The upper cover of the first and second oil purifier outer liners is fastened together by a double-body connector.

[0010] Furthermore, the first and second outer tanks of the oil purifier are arranged symmetrically to each other, and each of the first and second outer tanks includes a cylindrical outer tank body and a tank bottom located at the bottom of the outer tank body.

[0011] Furthermore, the abutting handles are located on the outer shell. The outer shells of the first and second oil purifiers are each equipped with two symmetrical abutting handles, and the bottom of the abutting handles abuts against the outer frame structure.

[0012] Furthermore, each abutting handle is located above the waist of the outer liner, and a reserved connecting liner is left between each abutting handle and the top of the outer liner.

[0013] Furthermore, the oil inlet pipe is connected to the bottom of the outer liner near the bottom of the liner, and a connecting pipe seat welded to the outer liner is provided between the oil inlet pipe and the outer liner. The connecting pipe seat passes through the inner and outer sides of the liner cavity.

[0014] Furthermore, the oil outlet is connected to the bottom of the bladder. The oil outlet includes a connecting plate and an expansion body arranged sequentially from top to bottom. The connecting plate is connected to the bladder cavity from top to bottom, and the connecting plate is connected to the expansion body from bottom to bottom. The bottom of the expansion body has a double outlet.

[0015] Furthermore, the upper cover is implemented by connecting the reserved inner tube to cover the outer inner tube.

[0016] Furthermore, vertically extending connecting strips are formed at the four corner edges of the upper cover. The closely spaced extending connecting strips of the upper cover of the first oil purifier outer liner and the upper cover of the second oil purifier outer liner together cross the double-body connector. The double-body connector is also fastened to the extending connecting strips by spot welding.

[0017] Furthermore, the dual-body connector includes a connecting body, the top of which has an upper opening groove, and the two sides of the middle part of the connecting body have adapter connecting strips that match the extension connecting strips.

[0018] A sealed centrifugal oil purifier innovatively transforms the traditional single-unit design of centrifugal oil purifiers into a dual-unit structure. The dual-unit, single-machine oil filtration mode doubles the oil filtration efficiency per unit time. Due to the use of identical components, manufacturing costs are effectively distributed, and the consumables of the frame structure are saved. Compared with two independent single-unit centrifugal oil purifiers, the dual-unit model of this application has a lower cost and huge market sales potential. In addition, by strengthening the fastening of the dual-unit connecting parts, the connection stability of the dual-unit model is further improved, effectively reducing vibration and noise.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-5As shown in the figure, this embodiment relates to a sealed centrifugal oil purifier. Compared with the traditional single-unit design, this embodiment is a two-unit structure. This embodiment does not redesign the inner tank, including the rotor assembly, motor, hollow shaft, oil distribution pan, and water collection pan. Only the outer tank structural components are designed. Therefore, the inner tank is not the content to be protected in this application. It is prior art and is not shown in this embodiment. In actual production and manufacturing, the inner tank with the required size and parameters can be customized.

[0027] This embodiment includes a first oil purifier outer tank 1 and a second oil purifier outer tank 2 arranged side by side. The dual-tank design enables a single unit to have dual filtration capabilities. Both the first oil purifier outer tank 1 and the second oil purifier outer tank 2 have abutment handles 6 formed on their outer surfaces. Both the first oil purifier outer tank 1 and the second oil purifier outer tank 2 have open tops and form a bladder cavity 5. Both the first oil purifier outer tank 1 and the second oil purifier outer tank 2 are provided with oil inlet pipes 7 that communicate with the bladder cavity 5. Both the first oil purifier outer tank 1 and the second oil purifier outer tank 2 are equipped with oil outlet parts 9 that communicate with the bladder cavity 5 at their bottoms. The upper open tops of the first oil purifier outer tank 1 and the second oil purifier outer tank 2 are sealed with upper covers 14 by O-rings. The upper covers 14 of the first oil purifier outer tank 1 and the upper covers 14 of the second oil purifier outer tank 2 are fastened together by a double-body connector 17.

[0028] In this embodiment, the first oil purifier outer liner 1 and the second oil purifier outer liner 2 are symmetrically arranged. Each of the first oil purifier outer liner 1 and the second oil purifier outer liner 2 includes a cylindrical outer liner body 3 and a liner bottom 4 located at the bottom of the outer liner body 3. Figures 1-2 As shown in the diagram, the bottom of the filter is a smooth transition, which facilitates the liquid phase falling under gravity and accelerates the oil filtration efficiency.

[0029] The abutting handle 6 is located on the outer liner 3. Each of the outer liner 3 of the first oil purifier 1 and the second oil purifier 2 is provided with two symmetrical abutting handles 6. That is to say, each of the first oil purifier 1 and the second oil purifier 2 is provided with two abutting handles 6. The two abutting handles 6 on each outer liner 3 are also symmetrical and located on the front and rear surfaces respectively. The bottom of the abutting handle 6 abuts against the outer frame structure. In actual production and manufacturing, the assembled first oil purifier 1 and the second oil purifier 2 are abutted against the frame structure through their respective abutting handles 6, thus supporting the first oil purifier 1 and the second oil purifier 2. In order to ensure a stable connection, the connection between the abutting handle 6 and the frame structure is welded. It should be noted that during the assembly process, the abutting handle 6 can also be used as a handle, making it convenient for operators to lift and raise.

[0030] Each abutting handle 6 is located above the waist of the outer liner 3, and a reserved connecting liner 13 is left between each abutting handle 6 and the top of the outer liner 3. The reserved connecting liner 13 is used for the connection depth of the upper cover 14, thereby increasing the stability of the connection between the first oil purifier outer liner 1 and the second oil purifier outer liner 2 and the upper cover 14. Correspondingly, the upper cover 14 is implemented by covering the reserved connecting liner 13 of the outer liner 3. When connecting, an O-ring is added to the edge of the opening of the upper cover 14 to enhance its sealing effect with the outer liner 3.

[0031] The oil inlet pipe 7 is connected to the bottom of the outer liner 3 near the bottom 4 of the liner. A connecting pipe seat 8 is welded to the outer liner 3 between the oil inlet pipe 7 and the outer liner 3. The connecting pipe seat 8 passes through the inner and outer sides of the connecting liner cavity 5. The connecting pipe seat 8 is used to enhance the resistance of the opening position and facilitates the connection with the oil inlet pipe 7 and strengthens the sealing of the connection. It can be understood that the oil inlet pipe 7 is used to input the oil to be treated into the inner liner of the first oil purifier outer liner 1 and the second oil purifier outer liner 2, respectively.

[0032] like Figure 3 As shown, the oil outlet 9 is connected to the bottom 4 of the tank. The oil outlet 9 includes a connecting plate 10 and an expansion body 11 arranged sequentially from top to bottom. The connecting plate 10 is connected to the tank cavity 5 upwards and to the expansion body 11 downwards. The bottom of the expansion body 11 has a double outlet 12. The connecting plate 10 is specifically a flange. A cavity is formed inside the expansion body 11. The cavity can increase the liquid outlet volume, thereby enhancing the liquid-repellent effect and helping to reduce the flow rate and prevent outlet splashing. The double outlet 12 in this embodiment is, as the name suggests, two adjacent and connected outlets, which further enhances the liquid discharge efficiency of the filtered oil.

[0033] like Figure 4 As shown, vertically extending connecting strips 15 are formed at the four corner edges of the upper cover 14. The closely spaced connecting strips 15 of the upper cover 14 of the first oil purifier outer liner 1 and the upper cover 14 of the second oil purifier outer liner 2 are connected to the double-body connector 17. The double-body connector 17 is also fastened to the connecting strips 15 by spot welding. Thus, the double-body connector 17 is used to limit the connection of the two upper covers 14 and ensure the connection stability of the upper body. In actual use, the standard cleaning time of the inner liner is about once every 5000-8000 hours, so it does not need to be disassembled for a long time. Therefore, the double-body connector 17 mentioned above in this application is spot welded to the connecting strips 15 to further ensure the connection is stable.

[0034] like Figure 5 As shown, the double-body connector 17 includes a connecting body 18. The top of the connecting body 18 is provided with an upper opening groove 20. The upper opening groove 20 is used for raising and erecting the power cord on site to ensure electrical safety. Adaptive connecting strips 19 that match the extension connecting strip 15 are formed on both sides of the middle part of the connecting body 18.

[0035] This application discloses a sealed centrifugal oil purifier, which innovatively transforms the traditional single-unit design of centrifugal oil purifiers into a dual-unit structure. The dual-unit, single-machine oil filtration mode doubles the oil filtration efficiency per unit time. Due to the use of identical components, manufacturing costs are effectively distributed, and the consumables of the frame structure are saved. Compared with two independent single-unit centrifugal oil purifiers, the dual-unit model of this application has a lower cost and huge market sales potential. In addition, by strengthening the fastening of the dual-unit connecting parts, the connection stability of the dual-unit model is further improved, effectively reducing vibration and noise.

[0036] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
