Description

Technical Field

[0001] This utility model relates to the field of ethanol gasoline processing technology, and specifically to an ethanol gasoline processing filtration device. Background Technology

[0002] Ethanol gasoline, a clean and environmentally friendly vehicle fuel, is made by adding a certain proportion of denatured fuel ethanol to gasoline, effectively reducing harmful emissions from vehicle exhaust. However, during production, storage, and transportation, ethanol gasoline is prone to contamination with impurities such as solid particles, gum, and moisture. If these impurities are not effectively removed, they can lead to problems such as clogged engine fuel systems and worn fuel injectors, severely affecting vehicle performance and engine life.

[0003] During the current production process of ethanol gasoline, solid impurities are easily present inside. These impurities can affect the normal use of ethanol gasoline and cause engine damage if used in a car for a long time. Therefore, ethanol gasoline needs to be filtered. However, the existing filtration of ethanol gasoline is insufficient, which easily causes solid impurities to accumulate at the bottom. The existing ethanol gasoline filter element can only be installed on the fuel tank. During the pre-treatment filtration (i.e., coarse filtration at the production end), some ethanol gasoline blending plants use simple filtration equipment, but it generally has the following problems: Incomplete filtration: The single-stage filter structure cannot intercept impurities of different particle sizes, resulting in uneven load on the filter element; Difficulty in draining: Impurities accumulate at the bottom of the equipment, requiring shutdown for disassembly and cleaning, affecting production efficiency; Poor adaptability: It is impossible to dynamically adjust the draining frequency according to the impurity content, which easily leads to gasoline waste or secondary pollution.

[0004] The prior art proposes a Chinese patent with publication number CN219167916U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A filter element for ethanol gasoline includes a central filter tube, pleated filter paper, end cap rings, an inner folded bottom edge, a sandwiched inner tube, and superabsorbent polymer cotton. The pleated filter paper is sleeved on the outside of the central filter tube. End cap rings are fixedly installed at both ends of the central filter tube. An inner folded bottom edge is fixedly installed inside the central filter tube near its lower end surface. A sandwiched inner tube is fixedly installed on the upper surface of the inner folded bottom edge. There is a gap between the outer surface of the inner tube of the jacketed filter and the inner wall surface of the central filter tube. Compared with the filter structure in the prior art, the filter element of this utility model places the superabsorbent polymer cotton on the inside of the folded filter paper. This allows ethanol gasoline to be filtered first through the folded filter paper and then through the superabsorbent polymer cotton to remove water, thus extending the service life of the superabsorbent polymer cotton. However, this device can only filter ethanol gasoline during use and cannot filter it in advance. This method is prone to causing excessive pressure on the filter element, which will cause the filter element to become clogged after long-term use, affecting the normal supply of gasoline. Utility Model Content

[0005] The purpose of this invention is to provide an ethanol gasoline processing and filtration device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An ethanol gasoline processing and filtration device includes an ethanol gasoline filter housing and a top cover. The housing forms a filter chamber inside, and the top cover is provided with an inlet pipe and an outlet pipe. The filter chamber is provided with a filter element inside, and the top cover is provided with a through hole for connecting the inlet pipe and the filter chamber. The filter element divides the filter chamber into an inner cavity and an outer cavity. The inner cavity is connected to the outlet pipe, and the outer cavity is connected to the inlet pipe through the through hole. The ethanol gasoline in the outer cavity enters the inner cavity after being filtered by the filter element.

[0008] Using the above technical solution, the filter element can separate ethanol gasoline. Ethanol gasoline enters the housing and is filtered by the filter element. The filtered ethanol gasoline enters the inner cavity, while the filtered solids remain in the outer cavity. This design facilitates the disassembly and assembly of the device, allows for easy removal of the filter element for replacement and cleaning, prevents the filter element from becoming clogged after prolonged use, and maintains the filter element's high filtration efficiency.

[0009] A further improvement of the present invention is that the filter element includes a frame and a filter screen mounted on the frame.

[0010] Using the above technical solution, the frame and filter screen can be easily disassembled and assembled, and the filter screen can be separated for cleaning.

[0011] A further improvement of the present invention is that the frame includes an inner frame and an outer frame connected together at the bottom, the filter screen is located between the inner frame and the outer frame, and a sealing cover is provided on the top of the frame.

[0012] The above technical solution integrates the inner and outer frames into a single unit, both of which are porous structures. The filter screen is placed between the inner and outer frames, and can be easily removed for cleaning by opening the top cover. This ensures a good seal between the filter element and the external structure, preventing leakage and enabling further filtration of solid impurities in ethanol gasoline.

[0013] A further improvement of this utility model is that: the bottom of the top cover is provided with a partition plate, and the partition plate is provided with a detachable filter plate.

[0014] Using the above technical solution, the partition plate is snapped onto the bottom of the top cover, and the filter screen is snapped onto the partition plate and the top cover. The filter screen can be easily removed for cleaning or replacement simply by removing the partition plate. This allows for the initial filtration of ethanol gasoline entering the housing, while also facilitating the cleaning of the filter screen.

[0015] A further improvement of this utility model is that: a drain pipe is connected to the bottom of the outer cavity, and a discharge pipe is connected to one side of the drain pipe; an adjusting component is provided inside the drain pipe.

[0016] Using the above technical solution, the sewage pipe and the discharge pipe are connected together, and the sludge in the outer cavity can be discharged through the sewage pipe and the discharge pipe, which facilitates internal cleaning.

[0017] A further improvement of the present invention is that the adjusting component includes a first plate and a second plate, and an adjusting rod is fixedly connected between the first plate and the second plate, with one end of the adjusting rod extending to the outside of the sewage pipe.

[0018] Using the above technical solution, plate one, plate two, and adjusting rod are fixed together. The adjusting rod extends to the outside of the sewage pipe, and the position of adjusting rod plate one and plate two can be adjusted from the outside, which facilitates the discharge of sludge, makes the sewage discharge process easy to control, and reduces gasoline loss.

[0019] A further improvement of this utility model is that a support ring is provided inside the sewage pipe.

[0020] Using the above technical solution, the support ring in the solution can limit the position of plate two, prevent plate one and plate two from overstepping their limits, and facilitate the discharge of sludge.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides an ethanol gasoline processing filtration device, which uses a filter element composed of a frame and a filter screen. The outer shell and the top cover can be fixed together. After a certain period of use, the internal filter screen can be removed for cleaning, which avoids excessive accumulation of solid impurities inside the device and facilitates the cleaning of the filtration device.

[0023] 2. This utility model provides an ethanol gasoline processing and filtration device, which uses an adjusting component consisting of a plate, a second plate, and an adjusting rod. By pushing and pulling the adjusting rod, the first and second plates can be moved. The sludge will not be discharged directly from the discharge pipe, but will stay between the first and second plates for a certain period of time, which can avoid excessive discharge at one time and waste of gasoline.

[0032] The present invention will be further described in detail below with reference to embodiments:

[0033] Example 1:

[0034] like Figures 1-6 As shown, this utility model provides an ethanol gasoline processing and filtration device, including an ethanol gasoline filter housing 1 and a top cover 2. The housing 1 forms a filter chamber inside. The top cover 2 is provided with an oil inlet pipe 3 and an oil outlet pipe 4. The filter chamber is provided with a filter element inside. The top cover 2 is provided with a through hole 5 for connecting the oil inlet pipe 3 and the filter chamber. The filter element divides the filter chamber into an inner cavity 6 and an outer cavity 7. The inner cavity 6 is connected to the oil outlet pipe 4, and the outer cavity 7 is connected to the oil inlet pipe 3 through the through hole 5. The ethanol gasoline in the outer cavity 7 enters the inner cavity 6 after being filtered by the filter element.

[0035] In this embodiment, the outer shell 1 and the top cover 2 are made of aluminum alloy. The outer shell 1 and the top cover 2 can be snapped together. The filter chamber is located inside the outer shell 1. The top cover 2 can be fixed to the top of the outer shell 1. The oil inlet pipe 3 and the oil outlet pipe 4 are integrally formed on the top cover 2. The filter element is located inside the filter chamber. The through hole 5 is opened on the top cover 2. The inner cavity 6 and the outer cavity 7 are separated by the filter element. The gasoline in the oil inlet pipe 3 can enter the outer cavity 7 through the through hole 5. The oil in the outer cavity 7 will be filtered by the filter element and then enter the inner cavity 6. During this process, solid impurities in the ethanol gasoline will be separated by the filter element and retained in the outer cavity 7. The filtered ethanol gasoline will be discharged from the oil outlet pipe 4, which facilitates the filtration of ethanol gasoline. The double-layer filtration of the filter plate 13 and the filter screen 8 can improve the removal rate of impurities.

[0036] like Figures 1-6 As shown in this embodiment, preferably, the filter element includes a frame and a filter screen 8 installed on the frame. The frame is made of polypropylene plastic, and the filter screen 8 can be placed inside the frame, which facilitates the replacement of the filter screen 8.

[0037] like Figure 1-6 As shown, preferably, the frame includes an inner frame 9 and an outer frame 10 connected at the bottom. The filter screen 8 is located between the inner frame 9 and the outer frame 10. The top of the frame is provided with a sealing cover 11. The inner frame 9 and the outer frame 10 are integrally formed. Multiple holes are opened on the inner frame 9 and the outer frame 10. The holes on the outer frame 10 are larger than those on the inner frame 9. The sealing cover 11 is snapped onto the top of the frame. The filter screen 8 can be easily replaced simply by opening the sealing cover 11.

[0038] Example 2:

[0039] like Figures 1-6 As shown, based on the embodiments, the present invention provides a technical solution: preferably, the bottom of the top cover 2 is provided with a partition plate 12, and the partition plate 12 is provided with a detachable filter plate 13.

[0040] In this embodiment, the partition plate 12 is snapped onto the bottom of the top cover 2, and the filter plate 13 is snapped onto the top cover 2 and the partition plate 12. Ethanol gasoline entering the outer cavity 7 will first be filtered by the filter plate 13, which can pre-treat the ethanol gasoline, filter out some of the solid impurities in the ethanol gasoline in advance, and improve the treatment effect of ethanol gasoline.

[0041] Example 3:

[0042] like Figures 1-6 As shown, based on the embodiments, the present invention provides a technical solution: preferably, a drain pipe 14 is connected to the bottom of the outer cavity 7, and a discharge pipe 15 is connected to one side of the drain pipe 14; an adjusting component is provided inside the drain pipe 14.

[0043] In this embodiment, the drain pipe 14 is connected to the bottom of the outer cavity 7, and the sludge in the outer cavity 7 can enter the drain pipe 14 to avoid excessive sludge accumulation inside the filter chamber. The discharge pipe 15 is connected to one side of the drain pipe 14, and the sludge in the drain pipe 14 will be discharged from the discharge pipe 15. The adjusting component can switch the opening and closing of the discharge pipe 15 to control the discharge of sludge and reduce the loss of ethanol gasoline.

[0044] Example 4:

[0045] like Figures 1-6 As shown, based on the embodiments, the present invention provides a technical solution: preferably, the adjusting member includes a first plate 16 and a second plate 17, an adjusting rod 18 is fixedly connected between the first plate 16 and the second plate 17, and one end of the adjusting rod 18 extends to the outside of the sewage pipe 14.

[0046] In this embodiment, plate 16 and plate 2 are fixed together by adjusting rod 18. When plate 16 and plate 2 are raised by adjusting rod 18, plate 16 will enter the outer cavity 7. The solids separated from the outer cavity 7 will enter between plate 16 and plate 2. At this time, plate 2 will be higher than the discharge pipe 15. When plate 2 falls to the lowest point, the solids between plate 16 and plate 2 will enter the discharge pipe 15. The inside of the sewage pipe 14 is provided with support rings 19. There are two support rings 19. The two support rings 19 can limit the position of plate 2 17 and prevent plate 16 and plate 2 17 from moving too much. When discharging sewage under high impurity conditions, the sewage discharge interval is shortened and the sludge is discharged quickly by frequently operating adjusting rod 18. When discharging sewage under low impurity conditions, the sewage discharge cycle can be extended and gasoline consumption can be reduced.

[0047] The working principle of this ethanol gasoline processing and filtration equipment will be explained in detail below.

[0048] like Figures 1-6 As shown, when assembling this filter device, the aluminum alloy outer shell 1 and the top cover 2 are first fixed with snaps to ensure that the sealing ring 20 is well sealed. When installing the filter element, the filter screen 8 is placed between the inner frame 9 and the outer frame 10 of the frame, and the top is sealed with the sealing cover 11. The whole is placed into the filter chamber. The partition plate 12 and the removable filter plate 13 are installed at the bottom of the top cover 2 for primary filtration. Ethanol gasoline enters from the inlet pipe 3 and flows into the outer cavity 7 through the through hole 5. The oil is coarsely filtered by the filter plate 13 and finely filtered by the filter screen 8. Solid impurities are retained in the outer cavity 7, and the clean oil enters the inner cavity 6 and is discharged from the outlet pipe 4.

[0049] When in use, first, ethanol gasoline is introduced into the filter chamber through the inlet pipe 3. As ethanol gasoline is continuously introduced, it will be filtered through the filter element and discharged from the outlet pipe 4. The filter element divides the filter chamber into an inner cavity 6 and an outer cavity 7.

[0050] When it is necessary to discharge sludge, first push the adjusting rod 18. The adjusting rod 18 will allow plate 16 to enter the outer cavity 7. At this time, plate 2 17 will follow the adjusting rod 18 to block the discharge pipe 15. When the sludge accumulated inside the outer cavity 7 enters the sewage pipe 14, pull the adjusting rod 18 outward. At this time, plate 16 will gradually enter the sewage pipe 14, and plate 2 17 will gradually lose its obstruction to the discharge pipe 15. At this time, the sludge between plate 16 and plate 2 17 will be discharged through the discharge pipe 15.

[0051] When the filter screen 8 needs to be cleaned, first open the top cover 2, then take out the filter element, remove the sealing cover 11 on the filter element, and then the filter screen 8 can be removed for cleaning. The filter plate 13 can be disassembled and reassembled by removing the partition plate 12. After cleaning, it can be reinstalled.

[0052] More specifically, a sealing ring 20 is provided between the top cover 2 and the outer shell 1. The sealing ring 20 is a commonly used rubber ring gasket. This sealing ring 20 is adapted to the size of the top cover 2 and the outer shell 1. The sealing ring 20 can reduce the leakage of ethanol gasoline and reduce the loss in the ethanol gasoline filtration process.

[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
