Description

Technical Field

[0001] This utility model relates to a filtration device, and more particularly to a filtration device for diesel engine oil production. Background Technology

[0002] Diesel engine oil filters are important equipment for filtering lubricating oil in diesel engines. Their main function is to remove impurities, gum, and other substances from the diesel engine oil to ensure its cleanliness and thus extend the engine's service life.

[0003] To ensure oil quality, some existing filtration devices employ multi-stage filtration, which is effective, but smaller pore sizes are more prone to clogging by metallic impurities and colloids, leading to decreased filtration efficiency over time. Furthermore, clogged filters typically require disassembly and cleaning, which is not only labor-intensive but also causes downtime and production disruptions. Therefore, developing a diesel engine oil filtration device capable of automatically cleaning the filter screen is essential. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, this utility model provides a diesel engine oil production filtration device, which improves the filtration effect and reduces maintenance costs by automatically cleaning the filter screen.

[0005] The technical solution is as follows: A filtration device for diesel engine oil production includes a housing and a filter element and a vertical shaft arranged coaxially within the housing; the filter element is a cylindrical structure with openings at both the top and bottom, and the filter element divides the internal space of the housing into a mixing zone inside the filter element and a filtrate zone outside the filter element; the vertical shaft passes through the upper end of the housing and is connected to a drive motor, the vertical shaft is a hollow structure with an opening at the top, and its upper opening is connected to a water supply end, the vertical shaft is provided with a scraper for cleaning the inner wall of the filter element and a cleaning part for cleaning the filter element, the cleaning part being in communication with the interior of the vertical shaft.

[0006] Preferably, the cleaning unit includes a cleaning unit body and a plurality of cleaning nozzles arranged circumferentially along the cleaning unit body.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model sets a vertical shaft coaxial with the filter element and drives the vertical shaft to rotate through a drive motor. At the same time, the scraper and the cleaning part rotate together. After the water supply is turned on, the cleaning liquid is sprayed out along the cleaning part to rinse the gaps of the filter element. The rotating scraper cleans the filter element.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0027] like Figure 1-2 As shown, a filtration device for diesel engine oil production includes a housing 1 and a filter element 2 and a vertical shaft 3 arranged coaxially within the housing 1. The shape of the housing 1 is not limited, but a cylindrical shape is preferred. The filter element 2 is a cylindrical structure with openings at both the top and bottom. The filter element 2 divides the internal space of the housing 1 into two regions: a mixing zone inside the filter element 2 and a filtrate zone outside the filter element 2. Diesel engine oil enters the mixing zone, is filtered by the filter element 2, and then enters the filtrate zone. Specifically, as shown... Figure 1 In the filter housing 1, the upper side wall is provided with an inlet 1a, one end of which extends to the mixing zone. The lower side wall of the filter housing 1 is provided with an outlet 1b, which is connected to the filtrate zone. The basic principle of filtration is that the liquid flows in from the filter inlet 1a, flows outward from the inner surface of the filter element 2, and flows out from the outlet 1b, thereby completing the filtration. The filter residue is left in the funnel-shaped collection chamber 11 at the bottom of the filtrate zone, which is specifically used to retain the filter residue. The collection chamber 11 is integrally formed with the filter housing 1. The lower end of the collection chamber 11 is provided with a drain port 1c, and a control valve is provided at the drain port 1c to open or close the drain port 1c at regular intervals.

[0028] like Figure 1-4As shown, the vertical shaft 3 passes through the upper end of the housing 1 and is connected to the drive motor 6. The drive motor 6 is fixedly mounted on the upper cover of the housing 1 via a frame 7. The drive motor 6 is a geared motor. The vertical shaft 3 and the drive motor 6 can be driven by gears, belt pulleys, or sprockets, etc., which is not limited here. It should be noted that the vertical shaft 3 is a hollow tubular structure with an open upper end and a closed lower end. The upper opening is connected to a water supply end (not shown in the figure), which is used to supply cleaning fluid to the vertical shaft 3. The liquid flowing into the vertical shaft 3 is preferably a high-pressure fluid. The vertical shaft 3 is provided with a cleaning section 5 for cleaning the filter element 2, and the cleaning section 5 is in communication with the interior of the vertical shaft 3. Specifically, the cleaning section 5 includes a cleaning section body 51 and a plurality of cleaning nozzles 52 arranged circumferentially along the cleaning section body 51.

[0029] like Figure 4 As shown, the cleaning nozzle 52 includes an upper nozzle 5a that is inclined upward along the body of the cleaning section 5 and a lower nozzle 5b that is inclined downward. By setting the upper nozzle 5a that is inclined upward and the lower nozzle 5b that is inclined downward, the gaps of the filter element 2 can be rinsed from different angles, resulting in a better and more thorough cleaning effect.

[0030] In addition, the vertical shaft 3 is also provided with a scraper 4 for cleaning the inner wall of the filter element 2. The scraper 4 includes a blade 41 with one end set on the side of the vertical shaft 3, and a blade head 42 set on the end of the blade 41 away from the vertical shaft 3. The blade head 42 is close to the inner wall of the filter element 2.

[0031] like Figure 3 As shown, specifically, the scraper 4 includes multiple blades 41 spirally arranged along the length direction of the vertical axis 3, such as... Figure 7 As shown, the tool holder 41 is elastically telescopic. The tool holder 41 includes a main rod and a secondary rod. The secondary rod is telescopically disposed inside the main rod, and a telescopic spring is provided inside the main rod.

[0032] like Figure 5 As shown, the side wall of the vertical shaft 3 is provided with a jacket, and a heating device 8 is provided inside the jacket. By setting the heating device, the cleaning liquid flowing through the vertical shaft 3 can be heated. The heated cleaning liquid can soften the impurities in the gaps of the filter element 2, making it easier to clean.

[0033] like Figure 1 and Figure 6 As shown, the lower end of the vertical shaft 3 extends to the sludge collection chamber 11, and a material transfer baffle 9 is provided at the lower end. The material transfer baffle 9 continuously transfers material to the sludge discharge port 1c while rotating. The material transfer baffle 9 can prevent the settled impurities from caking and blocking the sludge discharge port 1c, and can also transfer material to the sludge discharge port 1c, thus accelerating the sludge discharge efficiency.

[0034] After filtration, when a certain amount of impurities are intercepted on the surface of filter element 2, the drive motor 6 is started to drive the scraper 4, which is attached to the inner surface of filter element 2, to rotate. The water valve is opened to provide cleaning fluid to the vertical shaft 3. As the vertical shaft 3 rotates, the scraper 4 scrapes off the impurities on the inner surface of filter element 2. The cleaning nozzle 52 sprays cleaning fluid toward the inner wall of filter element 2 for rinsing. The impurities leave the surface of filter element 2 along the scraper 4 and fall into the collection chamber 11 at the bottom of the filter with the downward cleaning fluid. The impurities accumulate in the collection chamber 11 and the bottom of the equipment. The intelligent control valve opens automatically at timed intervals to discharge the liquid containing high concentrations of impurities from the drain port 1c. If necessary, the discharged residual liquid can be recycled and reused.

[0035] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
