Description

Technical Field

[0001] The present application relates to the technical field of engine oil treatment, and in particular to an engine oil settling tank. Background Art

[0002] Engine oil, also known as engine lubricant, is mainly composed of base oil and additives. Engine oil plays a vital role in the engine, including lubrication and wear reduction, auxiliary cooling and temperature reduction, sealing and leak prevention, rust and corrosion prevention, and shock absorption and buffering. However, when engine oil is circulated in mechanical equipment such as engines, it will inevitably be mixed with impurities such as water, dust, other miscellaneous oils, and metal powder or particles generated by wear of machine parts. These impurities will cause the engine oil to lose its original lubricating and protective properties after mixing with the engine oil. If the waste engine oil is directly treated by incineration or chemical methods, it will not only pollute the environment, but also increase the cost of engine oil treatment. For this reason, it is necessary to use an oil settling tank to treat the engine oil.

[0003] An oil settling tank is a device dedicated to oil treatment. It purifies oil by utilizing the density difference between oil, impurities and water. It is widely used in situations where high-quality oil is required, such as engine maintenance and oil regeneration.

[0004] Existing engine oil sedimentation tanks are usually composed of a vertical cylindrical tank body with partitions and diversion devices installed inside the tank body. When processing waste engine oil, you only need to pour the engine oil into the tank body and wait for it to settle naturally. Since the impurities and water in the waste engine oil have a large specific gravity, they will sink to the bottom of the sedimentation tank under the action of gravity, while the clean engine oil will float on top. After a period of sedimentation, the waste engine oil can be processed.

[0005] Although the above-mentioned oil settling tank can process waste oil, since the waste oil is used in a wide range of scenarios before being discarded and the degree of contamination of the oil varies, some waste oil may contain a lot of particulate impurities. If the waste oil containing a lot of particulate impurities is directly poured into the settling tank for natural sedimentation, the particulate impurities will cover the bottom of the settling tank. When the tank body after sedimentation is discharged, it may make it difficult to discharge the slag from the settling tank or difficult to clean the inside. Therefore, it is necessary to provide an oil settling tank to solve the above problems. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide an oil settling tank to solve the problem that the upper oil settling tank cannot pre-treat the oil and causes slag discharge difficulties.

The diameter of the lower end is larger than the diameter of the upper end and forms an installation step. A first spring is fixedly installed at the bottom of the cone, and the other end of the first spring is fixedly connected to the installation step.

[0009] Furthermore, the conical net is trumpet-shaped, and is divided into an inner ring close to the main shaft and an outer ring away from the main shaft.

[0010] Furthermore, an annular frame is fixedly installed in the tank body, and the annular frame is located at the bottom of the first filter plate.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0025] like Figure 1-Figure 2 As shown, the present application provides an engine oil sedimentation tank, including a main tank 1, which is the main body of the sedimentation tank and is a vertical cylindrical tank body for storing engine oil. The engine oil is settled in the main tank 1. A feed port 2 is provided at the upper end of the main tank 1, and the engine oil mainly enters the main tank 1 through the feed port 2. At the same time, a discharge port 3 is provided on the side of the main tank 1. The discharge port 3 is mainly used for discharging engine oil impurities and water after sedimentation. Thus, the waste engine oil is suitable for entering the main tank 1 through the feed port 2 for natural sedimentation. After sedimentation, the staff can extract the upper layer of engine oil through the feed port 2, and finally the remaining engine oil impurities and water can be discharged from the discharge port 3;

[0026] However, in order to avoid the main tank 1 from depositing a lot of impurities that are difficult to clean during discharge, the waste oil needs to be pre-treated, such as Figure 2-Figure 4 As shown, a secondary tank 4 is fixedly installed on the top of the main tank 1. The secondary tank 4 includes a tank body 41 provided on the main tank 1. A connecting bracket is fixedly installed on the top of the main tank 1. The other end of the connecting bracket is fixedly installed with the tank body 41, mainly serving to stabilize the secondary tank 4.

[0027] An inlet portion 42 is provided on the tank body 41, which is mainly used to facilitate the entry of waste oil. A discharge portion 43 is provided at the bottom of the tank body 41, and the other end of the discharge portion 43 is connected to the interior of the main tank 1. Thus, the waste oil can enter the tank body 41 through the inlet portion 42 for sedimentation, and then enter the main tank 1 through the discharge portion 43 for further sedimentation.

[0028] A main shaft 44 is disposed within the tank body 41. At least two sets of auxiliary rods 45 are fixedly connected to the upper and lower ends of the main shaft 44. The other ends of the auxiliary rods 45 are fixedly connected to the inner wall of the tank body 41, thereby fixing the main shaft 44 within the tank body 41. In this embodiment, the auxiliary rods 45 are inclined downwardly away from the main shaft 44, which is suitable for guiding the exhaust oil entering the tank body 41 to prevent a small amount of waste oil from being retained on the auxiliary rods 45.

[0029] like Figure 3-Figure 6A first filter plate 46 for filtering the exhaust oil is fixedly mounted in the tank body 41. The first filter plate 46 includes an outer frame 461 fixedly mounted in the tank body 41, and a conical net 462 fixedly connected to the outer frame 461. The conical net 462 is provided with a plurality of first filter holes to facilitate solid-liquid separation of the waste oil. A cone 49 is fixedly mounted at the center of the cone net 462. The cone 49 is slidably connected to the main shaft 44.

[0030] In this embodiment, the conical net 462 is made of rubber material. When subjected to an external force, the conical net 462 is adapted to deform. In its initial state, the conical net 462 is trumpet-shaped. For ease of explanation, the conical net 462 is divided into an inner ring close to the main shaft 44 and an outer ring away from the main shaft 44. When no force is applied, the inner ring is higher in level and continuously tilts downward near the outer ring. The outer ring is lower in level than the inner ring. When a large amount of solid oil particles and impurities accumulate on the conical net 462, gravity causes the inner ring to move downward. At this time, the inner ring is lower in level than the outer ring and tilts upward near the outer ring.

[0031] It can be understood that when the waste engine oil enters the tank body 41 through the feed part 42, it will pass through the first filter plate 46 for filtration, and the impurities in the engine oil will be preliminarily screened through the first filter hole. Impurities with a size larger than the first filter hole size cannot pass through the conical net 462 and accumulate on the conical net 462. Since the conical net 462 is inclined, it will preferentially roll toward the position of the outer frame 461. When the impurities accumulate to a certain extent, due to the action of gravity, the inner circle of the conical net 462 will move downward, and drive the cone 49 to move downward synchronously. At this time, the impurities will roll toward the main shaft 44 and accumulate at the main shaft 44. After all the engine oil has passed through the tank body 41 for pretreatment, the staff can judge the impurity content according to the deformation degree of the conical net 462, and estimate the oil sedimentation time according to the impurity content, so as to improve the efficiency of subsequent engine oil sedimentation.

[0032] like Figure 5-Figure 6 As shown in , the main shaft 44 is mainly composed of an upper end close to the feeding part 42 and a lower end close to the discharging part 43. The diameter of the lower end of the main shaft 44 is larger than the diameter of the upper end thereof and forms a mounting step. A first spring 410 is fixedly installed at the bottom of the conical body 49, and the other end of the first spring 410 is fixedly connected to the mounting step. In the initial state, the conical body 49 is located at a position away from the mounting step. When subjected to an external force, the conical body 49 is adapted to move downward toward the mounting step. When the external force is released, the conical body 49 is adapted to be reset by the rebound force of the first spring 410, so that after each oil pretreatment, the conical net 462 can be restored to its initial state.

[0033] In order to further improve the filtering effect of impurities, such as Figure 3-Figure 6 As shown, the conical body 49 is a conical setting with a larger upper portion and a smaller lower portion, and the diameter of the upper end thereof continuously decreases in the direction away from the feed portion 42. An annular frame 47 is fixedly installed in the tank body 41. The annular frame 47 is located at the bottom of the first filter plate 46. The interior of the annular frame 47 is hollow and forms an installation chamber. For the convenience of description, the installation chamber is divided into an outer port 471 close to the main shaft 44 and an inner port 472 away from the main shaft 44.

[0034] A second filter plate 48 is slidably installed in the installation chamber. In this embodiment, the second filter plate 48 is mainly composed of two groups of plates. The portion of the plate close to the main shaft 44 is provided with an arc surface (not shown in the figure). The arc surface contacts the outer surface of the cone 49. At the same time, a second spring 411 is fixedly installed between the two groups of plates. When subjected to external force, the two groups of plates are suitable for approaching or moving away. At the same time, the second spring 411 is suitable for stretching or compressing. In the initial state, the arc surface contacts the lower end of the outer ring of the cone 49. At this time, the outer ring of the plate Located at the outer port 471, when the conical body 49 moves downward, due to its larger upper and smaller lower configuration, the larger diameter portion of the conical body 49 moves downward. As the diameter of the conical body 49 contacted by the curved surface changes, the curved surface is squeezed outward by the conical body 49, causing the plates to move away from each other. In the initial state, at the same time, the outer ring of the plate moves from the outer port 471 toward the inner port 472. Conversely, when the conical body 49 gradually rises, the conical surface contacted by the curved surface changes from larger to smaller. Under the action of the second spring 411, the plates automatically return to their original position by approaching each other.

[0035] It should be noted that a second filter hole of the same size as the first filter hole is formed on the surface of the second filter plate 48. In the initial state, the first filter hole and the second filter hole completely overlap, and impurity particles of the same size as the first filter hole can be filtered. When the plate moves, the second filter hole moves synchronously, and the first filter hole and the second filter hole partially overlap, and can only filter smaller impurities.

[0036] When too much impurities accumulate on the first filter plate 46, the conical mesh 462 is deformed due to the action. The deformation of the conical mesh 462 drives the conical body 49 to move downward, compressing the first spring 410. Since the conical body 49 is an arc-shaped arrangement with a larger upper portion and a smaller lower portion, the arc-shaped surface is squeezed during its downward movement. The squeezed arc-shaped surface drives the plates away from each other, and the outer ring of the plate moves from the outer port 471 to the inner port 472. As a result, the first filter hole and the second filter hole partially overlap instead of completely overlapping initially, and only smaller solid impurities can be filtered.

[0037] In summary, when a batch of waste engine oil contains a large amount of solid impurities, the second filter plate 48 will be displaced under the influence of the first filter plate 46, thereby controlling the size of the filter holes and further screening the solid impurities, thereby improving the quality of engine oil pretreatment.

[0038] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
