Technical Field

[0001] The utility model relates to the technical field of diesel anti-wear agent impurity removal, in particular to a diesel anti-wear agent filtering and impurity removal device. Background Art

[0002] With the implementation of the China VI diesel standard, sulfur reduction technologies such as hydrotreating and hydrocracking have been adopted domestically, significantly reducing diesel sulfur content to below 10 parts per million (PPM). However, since the lubricity of diesel fuel primarily comes from sulfur-containing substances, reducing the sulfur content also reduces diesel lubricity. Due to the poor lubricity of low-sulfur diesel, high-pressure fuel pumps and injectors in diesel engines can rapidly wear out and fail. Therefore, low-sulfur and ultra-low-sulfur diesel fuels are often treated with lubricity additives (diesel antiwear agents) to improve their lubricity.

[0003] Industrially prepared diesel anti-wear agent needs to go through a filtering and impurity removal process before it can meet factory requirements. For example, the Chinese utility model patent CN201520068202.X discloses a diesel anti-wear agent filtering and impurity removal device. The material is fed through a feed port provided on the rotating shaft, and the filter barrel is driven by a motor to stir. Through centrifugal action, impurities in the diesel anti-wear agent are thrown into the brush, and the moisture in the diesel anti-wear agent is removed through the second filter tank. At the same time, when cleaning, the filter barrel can be disassembled as a whole, which makes cleaning convenient and thorough.

[0004] However, the device disclosed in the above-mentioned document still has certain defects. The device cannot completely remove impurities in the diesel anti-wear agent by utilizing centrifugal action in combination with a brush. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0027] like Figures 1 to 5 In the embodiment of the diesel anti-wear agent filtering and impurity removal device of the present invention shown, the diesel anti-wear agent filtering and impurity removal device includes a centrifugal turntable 1 and a base 2, and the centrifugal turntable 1 and the base 2 are rotatably connected via a bearing.

[0028] The centrifugal turntable 1 is a cylindrical multi-step boss with multiple steps. The cylindrical shape can be a cylinder or a regular prism, such as a regular decagonal prism, a regular dodecagonal prism, etc. The cylindrical shape of each step can be different or the same, and each step is coaxial with the central step of the centrifugal turntable 1 so that the centrifugal turntable 1 will not lose its roundness when rotating as a whole.

[0029] A filter plate 11 is fixed to the side wall of each step of the centrifugal turntable 1. The filter plate 11 covers the side wall of the step on which it is located. Specifically, the filter plate 11 can be fixed to the centrifugal turntable 1 in a spiral manner; the closer the filter plate 11 is to the center of the centrifugal turntable 1, the larger the filter hole on it. This allows the multi-stage filter plates 11 to filter impurities of different particle sizes, thereby accelerating the filtration and impurity removal process.

[0030] A filter element 12 is fixed to the top surface of each step of the centrifugal turntable 1. This cylindrical element 12 has a bottom surface. The bottom surface of the filter element 12 on the center step is not perforated, while the bottom surfaces of the filter elements 12 on the other steps are perforated to facilitate placement on their respective steps. The filter element 12 covers the top surface of a single step and the inner wall of the filter plate 11 located on the sidewall of that step. The closer the filter element 12 is to the center of the centrifugal turntable 1, the larger its filtration gap. This allows multiple stages of filter elements 12 to filter impurities of varying sizes, accelerating the filtration and impurity removal process.

[0031] A collection shell 21 is provided on the outermost step of the centrifugal turntable 1 and the outermost filter plate 11 to collect the filtered diesel anti-wear agent. The collection shell 21 is fixedly connected to the base 2; a feed pipe 22 is provided at the upper end of the central step of the centrifugal turntable 1, and the feed pipe 22 extends into the interior of the filter element 12 on the central step.

[0032] In this embodiment, the filter plate 11 mainly plays the role of a baffle to prevent the side wall of the filter element 12 from being deformed due to the lack of a baffle. The filter holes on the filter plate 11 can also play a certain filtering role; the filter element 12 plays the main filtering role. When there are too many impurities accumulated on the filter element 12, the filter element 12 can be conveniently removed for cleaning or replacement; a multi-step stepped centrifugal filtration scheme is adopted. On the one hand, the impurity removal and filtration process can be carried out quickly, and the diesel anti-wear agent can be filtered and removed from the center to the outermost step without too much hindrance by centrifugal action. On the other hand, the diesel anti-wear agent can be filtered and removed to a higher standard, and the impurities in the diesel anti-wear agent can be removed more thoroughly.

[0033] In one embodiment of the present application, preferably, the bottom surface of the centrifugal turntable 1 is provided with a multi-step concave platform corresponding to the boss, which can reduce the weight of the centrifugal turntable 1 on the one hand, and on the other hand, the bottom surface can be conveniently embedded in the rotating flange 31 of the drive assembly 3 to drive the centrifugal turntable 1 to rotate.

[0034] In one embodiment of the present application, preferably, a drive assembly 3 is also included, which includes a rotating flange 31, a drive shaft 32 and a motor 33. The rotating flange 31 and the drive shaft 32 are both coaxially arranged with the centrifugal turntable 1. The rotating flange 31 is fixed to the bottom surface of the centrifugal turntable 1. The rotating flange 31 is driven to rotate by the motor 33. The bottom surface of the rotating flange 31 is rotatably connected to the upper end surface of the base 2 through a bearing 34. The drive shaft 32 is passed through the upper end surface of the base 2 and is rotatably connected to the base 2 through another bearing.

[0035] In one embodiment of the present application, preferably, the common center of gravity of the centrifugal turntable 1 and the accessories fixed thereon is on the axis of the centrifugal turntable 1, and the relevant fixed accessories may include a filter plate 11, a filter element 12, a rotating flange 31, a drive shaft 32, etc., to ensure that the centrifugal turntable 1 does not deviate from its rotation axis during rotation.

[0036] In one embodiment of the present application, preferably, the rotating flange 31 is embedded in the bottom concave portion of the centrifugal turntable 1 and contacts each concave portion, so that the rotating flange 31 can effectively fix and support the centrifugal turntable 1 .

[0037] In one embodiment of the present application, preferably, the collecting shell 21 includes an inner retaining wall 212, which extends into the bottom recess of the centrifugal turntable 1 to prevent the diesel anti-wear agent from accidentally splashing out, and there is a certain gap between the inner retaining wall 212 and the centrifugal turntable 1 and the rotating flange 31 to prevent interference.

[0038] In one embodiment of the present application, preferably, the collecting shell 21 is provided with an inclined bottom channel 213, the inner retaining wall 212 is provided on the upper surface of the bottom channel 213, and the lowest point of the bottom channel 213 is provided with a discharge port 214 to facilitate the collection of the filtered diesel anti-wear agent; on the collecting shell 21, it continues to extend inward along the bottom channel 213 and conflicts with the base 2, and a fixing ring 215 is provided around the outer wall of the base 2, and the collecting shell 21 is fixedly connected to the base 2 through the fixing ring 215.

[0039] In one embodiment of the present application, preferably, the collecting shell 21 includes an outer baffle wall 211, which is inclined outward from top to bottom, so that after the diesel anti-wear agent thrown out due to centrifugal action is thrown onto the outer baffle wall 211, it will smoothly slide from the outer baffle wall 211 to the bottom channel 213 due to gravity; the top height of the outer baffle wall 211 is greater than the top height of the outermost filter plate 11, and in addition, the top of the outer baffle wall 211 is also provided with a top cover 216, and the center of the top cover 216 is provided with a central through hole through which the feed pipe 22 can pass; the outer baffle wall 211 and the top cover 216 jointly prevent the diesel anti-wear agent from accidentally splashing out.

[0040] In one embodiment of the present application, preferably, a hard skeleton is provided in the filter element 12. The hard skeleton enables the filter element 12 to be clamped and fixed by the centrifugal turntable 1 and the filter plate 11, and can also prevent the filter element 12 from being deformed due to centrifugal force.

[0041] In one embodiment of the present application, preferably, the height of the step is greater than the bottom thickness of the filter element 12 within the outer step, so that in the process of the diesel anti-wear agent being centrifuged from the center to the periphery, the filter element 12 is always lower than the height of the step and will not hinder the filtration of the diesel anti-wear agent.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
