Description

Technical Field

[0001] The present application relates to the technical field of lubricating oil storage, and in particular to a lubricating oil circulating constant temperature storage device. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

[0003] Existing lubricating oil storage methods often store it in a tank body. However, in cold weather, the lubricating oil in the tank body will gradually solidify, affecting its use. The patent document with announcement number CN212686402U discloses a lubricating oil circulating constant temperature storage device. The lubricating oil can be sucked into the heating circulation pump for heating through a first circulation heating pipe, and then the heated lubricating oil is discharged through a second circulation heating pipe. In this way, the lubricating oil in the lubricating oil storage device body can be continuously circulated and heated, which has certain positive significance. However, there are also certain disadvantages. For example, when the lubricating oil level inside the tank body gradually drops, a small amount of lubricating oil will adhere to the exposed inner wall inside the tank body. Due to the lack of flow and heat transfer between the lubricating oil, the lubricating oil attached to the lubricating oil tank body will become hardened or even deteriorate, thereby affecting the use of the remaining lubricating oil inside the tank body, and also causing certain pollution to the tank body.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0026] like Figure 1-6 As shown, the lubricating oil circulating constant temperature storage device includes a tank body 1, within which is a chamber 2 for storing lubricating oil. To maintain the lubricating oil at a constant temperature, an annular heating chamber 3 is formed on the outer wall of the tank body 1. A first inlet 31 is provided at the bottom of the annular heating chamber 3 for introducing heat medium, while a first outlet 32 ​​is provided at the top of the annular heating chamber 3 for discharging the heat medium. This allows the heat medium to circulate within the annular heating chamber 3, providing a continuous heating effect for the tank body 1.

[0027] The heat medium can be circulated between the first inlet 31 and the first outlet 32 ​​by a pump component.

[0028] The heat medium may be heated water.

[0029] The annular heating chamber 3 can be specifically formed by enclosing an annular shell and the outer wall of the tank body 1. In actual practice, the tank body 1 is nested inside the annular shell.

[0030] By setting an annular heating chamber 3 on the outside of the tank body 1, the temperature of the entire accommodating chamber 2 can be effectively increased to prevent the lubricating oil on the inner wall of the accommodating chamber 2 from becoming hardened. Since the annular heating chamber 3 is set on the outer wall of the tank body 1, it can also play a certain insulation role for the accommodating chamber 2, thereby better providing constant temperature protection for the lubricating oil inside the accommodating chamber 2.

[0031] Furthermore, a heating pipe 4 is installed at the bottom plate of the accommodating chamber 2. Both ends of the heating pipe 4 pass through the outer wall of the accommodating chamber 2 and are located outside the tank body 1. The heating pipe 4 is also used to circulate the heat medium, thereby enhancing the heating effect on the lubricating oil. The heat medium in the annular heating chamber 3 and the heating pipe 4 can be heated by external heating equipment and then circulated and pumped in, ensuring a continuous supply and circulation of the heat medium.

[0032] To prevent the lubricating oil from settling or condensing during storage, a stirring shaft 5 is provided in the receiving chamber 2, and a stirring blade 6 is provided on the stirring shaft 5. The stirring shaft 5 can be driven to rotate by an external motor 15, thereby driving the stirring blade 6 to stir the lubricating oil in the receiving chamber 2 to maintain a uniform state.

[0033] Specifically, the motor 15 is located outside the top of the tank.

[0034] To further improve the efficiency and uniformity of lubricating oil heating, a drainage tube 7 is installed on the tank body 1. The lower and upper sections of the drainage tube 7 are located inside the accommodating chamber 2, while the middle section is located outside the accommodating chamber 2. A pump body 8 is installed in the middle section of the drainage tube 7 to extract the lubricating oil from the bottom of the accommodating chamber 2 and pump it to the spray rack 9. The spray rack 9 is equipped with spray holes 91, which spray the lubricating oil evenly back into the accommodating chamber 2, thereby achieving cyclic heating and improving the fluidity of the lubricating oil.

[0035] Specifically, the spray rack 9 comprises an annular tube 92, a relief ring 93 located within the annular tube 92, and a plurality of diverter tubes 94. These diverter tubes 94 are spaced circumferentially, with their central ends interconnected with the outer ring of the relief ring 93, while their distal ends connect to the inner ring of the annular tube 92. Spray holes 91 are positioned on the annular tube 92, facing the inner wall of the accommodating chamber 2. This ensures that the lubricating oil is evenly sprayed onto the inner wall of the accommodating chamber 2, promoting fluidity and preventing consolidation.

[0036] In order to allow the stirring shaft 5 to pass through the spray rack 9 smoothly, a clearance hole 931 is provided in the clearance ring 93, and the stirring shaft 5 is arranged through the clearance hole 931 and is rotatably connected to the clearance hole 931. In this way, the stirring shaft 5 will not be interfered by the spray rack 9 during rotation.

[0037] Specifically, the stirring shaft 5 and the clearance hole 931 can be matched through a bearing.

[0038] In practice, the upper and lower sections of the drainage tube 7 are relatively centrally located within the accommodating chamber 2 to ensure heat preservation. To avoid the stirring blade 6, the stirring blade 6 is positioned on the stirring shaft 5 at a height corresponding to the middle section of the drainage tube 7. This allows the stirring blade 6 to avoid interference with the drainage tube 7 when the stirring shaft 5 rotates.

[0039] In addition, an auger blade 10 is provided on the stirring shaft 5 at a height corresponding to the upper middle section of the drainage tube 7. The auger blade 10 can generate an upward thrust when the stirring shaft 5 rotates, helping to push the lubricating oil at the bottom of the accommodating chamber 2 upward, thereby further improving the fluidity of the lubricating oil and uniformly heating the lubricating oil.

[0040] In order to facilitate the injection and discharge of lubricating oil into the tank body 1, an oil filling port 11 is provided at the top of the tank body 1, and an oil outlet 12 is provided at the bottom of the tank body 1. In this way, the injection and discharge operations of the lubricating oil can be easily achieved.

[0041] In order to improve the stability and service life of the tank body 1, the bottom of the tank body 1 is also provided with supporting legs 13. The supporting legs 13 can disperse the weight of the tank body 1 and prevent it from directly contacting the ground and being damaged.

[0042] In addition, to protect the middle section of the drainage tube 7 and the pump body 8 from interference and damage from the external environment, a protective box 14 is also provided on the outer wall of the tank body 1. The middle section of the drainage tube 7 and the pump body 8 are both placed in the protective box 14, which effectively prolongs their service life and ensures their normal operation. At the same time, the insulation material in the protective box 14 can be heated to prevent the temperature of the lubricating oil flowing through this section from dropping.

[0043] In other embodiments, a temperature sensor may be provided on the tank body 1 to detect the temperature of the lubricating oil, thereby realizing the storage of the lubricating oil in a scientific and reasonable manner.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
