Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil impurity removal, in particular to a lubricating oil impurity removal device for an oil pump. Background Art

[0002] The function of the oil pump is to increase the oil to a certain pressure and then force it to the moving surfaces of various parts of the engine. It is used to increase the oil pressure and ensure a certain amount of oil, and to force oil to be supplied to various friction surfaces. It is widely used in internal combustion engines and engineering fields such as semiconductors and solar energy. When the oil pump is running, the engine works, and the driving gear on the camshaft drives the transmission gear of the oil pump, so that the driving gear fixed on the driving gear shaft rotates, thereby driving the driven gear to rotate in the opposite direction, and sending the oil from the oil inlet chamber along the tooth gap and the pump wall to the oil outlet chamber.

[0003] In order to prevent the oil pump from being clogged due to impurities in the lubricating oil, the lubricating oil will be filtered and impurity-removed before entering the oil pump. During the process, most impurity-removing devices use a rotating scraper structure to scrape the impurities on the filter screen evenly to avoid clogging of the filter screen, but the impurities on the filter screen cannot be removed. After a long period of filtration, the filter screen is still prone to clogging, and even if the impurities are scraped evenly, they will still block the filter screen, resulting in a reduction in the filtration efficiency of the filter screen. For this reason, we propose a lubricating oil impurity-removing device for an oil pump. Utility Model Content

[0018] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 4 The present embodiment is a lubricating oil impurity removal device for an oil pump, comprising an impurity removal box 1, the top and bottom surfaces of which are respectively fixed with an oil inlet 2 and an oil outlet 3, a motor 4 is arranged at the rear side of the impurity removal box 1, and driving rollers 5 are rotatably connected to the impurity removal box 1 at symmetrical positions inside the impurity removal box 1 through bearings, the rear end of the upper driving roller 5 passes through the rear side of the impurity removal box 1 and is fixed on the output shaft of the motor 4, a filter mesh belt 6 is transmission-connected between the two driving rollers 5, a collecting box 7 is fitted on the bottom surface of the top of the filter mesh belt 6, and a filter bottom net 8 is fixed on the bottom surface of the inner part of the collecting box 7, support plates 9 are symmetrically arranged on the bottom surface of the collecting box 7, and the outer sides of the support plates 9 are all fixed on the inner wall of the impurity removal box 1 for supporting the collecting box 7, a sealing plate 10 is fixed on one end of the collecting box 7 extending to the outside of the impurity removal box 1, and a material shifting assembly is arranged on the upper inner part of the filter mesh belt 6.

[0020] In this embodiment, the oil inlet 2 and the oil outlet 3 are located at the lower part of the filter mesh belt 6 to prevent the lubricating oil from being directly poured into the collecting box 7. A guide plate 20 is fixed on the side wall of the impurity removal box 1 below the oil inlet 2, and the bottom surface of the guide plate 20 is slidably fitted with the top surface of the filter mesh belt 6 to guide the lubricating oil. The guide plate 20 is used to perform guiding and limiting to ensure that the lubricating oil can be filtered by the two filter mesh belts 6 and then flow out through the oil outlet 3.

[0021] In this embodiment, a guide plate 18 is fixed inside the impurity removal box 1 on the side of the oil outlet 3 and is inclined downward toward the oil outlet 3. The guide plate 18 is used to guide the filtered lubricating oil. The height of the guide plate 18 is less than the height from the bottom surface of the support plate 9 to the bottom surface of the inner bottom of the impurity removal box 1. The lubricating oil is guided by the guide plate 18 so that the filtered lubricating oil can flow to the oil outlet 3, making it convenient for the lubricating oil to be discharged through the oil outlet 3.

[0022] In this embodiment, the material-discharging assembly includes a rotating rod 14, a material-discharging plate 15, a pulley 16 and a transmission belt 17. The rotating rod 14 is rotatably connected to the inner wall of the dust collecting box 1 inside the filter mesh belt 6 through a bearing, and a plurality of material-discharging plates 15 are equidistantly fixed on the outer surface of the rotating rod 14. The rotating rod 14 extends to one end of the rear side of the dust collecting box 1 and the output shaft of the motor 4 at the rear side of the dust collecting box 1 are both fixed with pulleys 16. The two pulleys 16 are connected by a transmission belt 17. The filter mesh belt 6 is moved by the material-discharging plate 15, so that impurities on the bottom surface of the filter mesh belt 6 can be shaken off into the collection box 7, which is convenient for collecting impurities.

[0023] In this embodiment, a limiting plate 19 is fixed to the inner top surface of the impurity removal box 1 above the collecting box 7, and one end of the collecting box 7 extending into the interior of the impurity removal box 1 is arranged to be inclined to cooperate with the filter mesh belt 6, so that the collecting box 7 can scrape impurities on the bottom surface of the filter mesh belt 6, and the lubricating oil is further blocked by the limiting plate 19 to prevent the lubricating oil from falling on the upper part of the filter mesh belt 6, thereby ensuring the filtering distance of the lubricating oil.

[0024] In this embodiment, a handle is symmetrically fixed on the outside of the sealing plate 10, and a fixing rod 11 is symmetrically fixed on the outside of the sealing plate 10. A limiting clamp plate 12 is rotatably sleeved on the fixing rod 11. The bottom of the limiting clamp plate 12 is hung on the fixing clamp rod 13, and the fixing clamp rod 13 is fixed on the side wall of the debris removal box 1, which is used to fix the sealing plate 10. The sealing plate 10 is limited by the limiting clamp plate 12 and the fixing clamp rod 13 to ensure the stability of the collecting box 7 after insertion.

[0025] In this embodiment, the length of each unloading plate 15 is equal to the width of the filter mesh belt 6, and the width of the filter mesh belt 6 is greater than the width of the oil inlet 2 and the oil outlet 3. The width of each unloading plate 15 is greater than the vertical distance from the rotating rod 14 to the inner bottom surface of the filter mesh belt 6, ensuring that after the unloading plate 15 is rotated to the bottom, the filter mesh belt 6 can be moved to facilitate the falling of impurities on the bottom surface of the filter mesh belt 6 above the collection box 7, thereby avoiding obstruction and blockage caused by residual impurities on the surface of the filter mesh belt 6.

[0026] Working principle: when it is necessary to remove impurities from the lubricating oil, the lubricating oil enters the impurity removal box 1 through the oil inlet 2, and the motor 4 is turned on, so that the motor 4 runs to drive the driving roller 5 to rotate, and the filter belt 6 can be driven to move through the driving roller 5. When the filter belt 6 moves, the motor 4 drives the pulley 16 on its output shaft to rotate at the same time, and the transmission belt 17 can drive the pulley 16 on the rotating rod 14 to rotate, thereby driving the rotating rod 14 to rotate. When the rotating rod 14 rotates, it drives the unloading paddle 15 to make a circular motion. At this time, the lubricating oil falls on the filter belt 6 and is filtered through the filter belt 6. After filtering, it flows to the bottom surface of the impurity removal box 1, and the filter belt 6 with impurities on the surface moves upward. When it moves to the top of the collecting box 7, the unloading paddle 15 pokes the filter belt 6 during its rotation, and at this time, the side of the filter belt 6 with impurities faces downward. Under the prying of the unloading paddle 15, the impurities fall into the collecting box After falling, the filter bottom net 8 filters out the impurities inside the collection box 7, and the lubricating oil on the impurities flows down to the bottom of the impurity removal box 1, and then the filter belt 6 continues to move. When it moves to the side of the collection box 7, the top surface of the collection box 7 scrapes and cleans the bottom of the filter belt 6 for the second time, and the impurities on the bottom of the filter belt 6 can be completely removed. The cleaned filter belt 6 continues to move below the oil inlet 2 under the drive of the driving roller 5, and the lubricating oil can be continuously filtered. When there are many impurities collected in the collection box 7, the limiting card plate 12 is rotated to separate the limiting card plate 12 from the fixed card rod 13, so that the limit of the sealing plate 10 can be released, and the collection box 7 can be pulled out by holding the handle, and the impurities inside the collection box 7 can be poured out, and the collection box 7 can be inserted into the interior of the impurity removal box 1, and the support plate 9 supports it. Finally, the limiting card plate 12 is rotated and sleeved on the fixed card rod 13, and the collection box 7 can be fixed.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
