Description

Technical Field

[0001] This utility model relates to the field of fuel filtration technology, and in particular to a fuel filtration and purification device. Background Technology

[0002] Fuel often contains solid impurities such as metal shavings, dust, and rust, which can severely wear down high-precision components such as fuel injectors and fuel pumps, leading to equipment failure.

[0003] In the existing technology, fuel needs to be filtered through a filter device before use to remove impurities and reduce the possibility of equipment failure.

[0004] After a period of use, the filter needs to be cleaned of impurities inside. The impurities attached to the inner side wall of the device need to be removed by workers using tools such as brushes, which is difficult and reduces the cleaning efficiency of the filter tank. Utility Model Content

[0005] To address the technical problem in existing technologies where impurities adhering to the inner sidewalls of filter tanks are difficult to clean, requiring workers to use brushes and other tools for removal, resulting in high cleaning difficulty and low cleaning efficiency, this utility model provides a fuel filtration and purification device.

[0006] The fuel filtration and purification device provided by this utility model adopts the following technical solution: A fuel filtration and purification device includes a filter tank and a filter disposed inside the filter tank. An inlet is provided on the upper part of the side wall of the filter tank, and a drain outlet is provided on the lower part of the side wall of the filter tank. A base is fixedly disposed at the bottom of the filter tank, and the bottom of the filter is fixedly mounted on the base. A fixing plate is sleeved on the upper part of the filter. A rod fixing mechanism is rotatably connected to the fixing plate to fix the installation position of the fixing plate. A decontamination removal mechanism for scraping off impurities adhering to the inner wall of the filter tank is screwed externally to the rod fixing mechanism.

[0007] By adopting the above technical solution, the filter is installed in the filter canister through the chassis and fixed plate to filter and purify the fuel. When cleaning the inside of the filter canister, the dirt removal mechanism scrapes off the impurities attached to the inner side wall of the filter canister, eliminating the need for workers to use brushes or other tools to clean it. This reduces the difficulty of cleaning the filter canister and improves the cleaning efficiency of the filter canister.

[0008] Furthermore, the filter tank has an opening at the top, and a cover is provided on the opening at the top of the filter tank. A flow guide tank is fixedly provided at the bottom of the chassis. The flow guide tank is connected to the filter. The bottom of the flow guide tank has a discharge port, and a support is provided on the side of the flow guide tank.

[0009] By adopting the above technical solution: the filtered and purified fuel flows into the diversion tank through the filter and finally flows out through the outlet. The support makes a certain storage space between the bottom of the outlet and the ground. Users can place the fuel storage device in the storage space to collect and store the fuel, or connect it to the outlet through a pipe to transfer the filtered fuel in the diversion tank.

[0010] Furthermore, the chassis has multiple threaded holes, and the bottom of the filter is locked in the threaded holes to fix the bottom of the filter. The fixing plate has fixing holes that cooperate with the filter, and the fixing holes are fitted onto the upper end of the filter.

[0011] By adopting the above technical solution, the chassis fixes the lower end of the filter, and the fixing plate fixes the upper end of the filter.

[0012] Furthermore, the rod fixing mechanism includes a fixing sleeve and a fixing shaft slidably disposed inside the fixing sleeve. The upper part of the fixing sleeve is provided with two bosses, and the fixing disc is rotatably disposed between the two bosses.

[0013] By adopting the above technical solution, the rod fixing mechanism and the fixed plate are rotatably connected.

[0014] Furthermore, the top of the fixed shaft has a pull plate, the bottom of the pull plate has a limiting plate, the bottom of the fixed shaft is also provided with a triangular connecting claw, the bottom of the fixed sleeve has an inclined wall that cooperates with the side wall of the triangular connecting claw, and the chassis is provided with a conical groove that cooperates with the triangular connecting claw.

[0015] By adopting the above technical solution: under the elastic force of the triangular connecting claw, the triangular connecting claw slides downward along the inclined wall, and the limiting plate stops at the upper end of the fixed sleeve, thereby limiting the extreme position of the downward movement of the triangular connecting claw by the limiting plate.

[0016] Furthermore, a fixing beam is welded to the bottom of the fixed plate, and a connection hole for connecting the fixing beam is opened on the chassis.

[0017] By adopting the above technical solution, the fixed beam is inserted into the connecting hole to prevent the fixed plate from rotating during the process of fixing the filter.

[0018] Furthermore, the decontamination mechanism includes a connecting block and a circular spring. A thread is provided around the outer wall of the fixed sleeve at the bottom of the boss. The connecting block is screwed onto the fixed sleeve. Multiple connecting ribs are evenly welded to the outside of the connecting block. A connecting ring is welded to the end of the connecting rib. A circular spring is welded to the end of the connecting ring. The circular spring forms a sliding connection with the inner wall of the filter tank.

[0019] By adopting the above technical solution: rotating the fixed sleeve allows the connecting ring to drive the circular spring to slide downward on the inner wall of the filter tank, thereby scraping away the impurities attached to the inner wall of the filter tank.

[0020] Furthermore, a groove is provided on the side of the fixed beam in the vertical direction, and a slider is located on one of the connecting ribs, which is slidably disposed in the groove on the side of the fixed beam.

[0021] By adopting the above technical solution, the connecting bars can slide downwards along the fixed beam.

[0022] Furthermore, a drive ring for driving the fixed sleeve to rotate is also provided at the upper end of the fixed sleeve.

[0023] By adopting the above technical solution: by rotating the drive ring, the drive ring drives the fixed sleeve to rotate.

[0024] In summary, the beneficial effects of this utility model are as follows: This invention, through the setting of a rod fixing mechanism and a decontamination mechanism, allows fuel to be fed into the filter tank through the inlet during use. The fuel is filtered and purified by the filter, then enters the filter's interior and flows into the guide tank through an opening at the bottom of the filter. Finally, it is discharged outwards through the outlet at the bottom of the guide tank. When cleaning impurities inside the guide tank, the drive ring in the rod fixing mechanism is rotated. The drive ring drives the fixing sleeve to rotate on the chassis. During this rotation, the fixing sleeve drives the connecting ring in the decontamination mechanism to slide vertically downwards along the fixed beam. At this time, the circular spring in the decontamination mechanism slides downwards on the inner wall of the filter tank, scraping away the impurities adhering to the inner wall. Finally, the impurities are discharged from the filter tank through the drain outlet. This device eliminates the need for workers to use brushes or other tools to clean the inner sidewalls of the filter tank, reducing the difficulty of cleaning and improving the cleaning efficiency.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model discloses a fuel filtration and purification device, including a filter tank 1 and a filter 5 disposed inside the filter tank 1 to filter the fuel inside the filter tank 1. Specifically, a cover 4 is provided at the top of the filter tank 1 to cover the top opening of the filter tank 1, an inlet 12 connected to the filter tank 1 is provided at the upper part of the side wall of the filter tank 1, and a drain outlet 13 connected to the filter tank 1 is provided at the lower part of the side wall of the filter tank 1. During use, fuel is transported into the filter tank 1 through the inlet 12 for filtration, and impurities filtered out inside the filter tank 1 are discharged outward through the drain outlet 13. A guide tank 2 connected to the filter 5 is welded at the bottom of the filter tank 1. The bottom of the guide tank 2 has a discharge outlet 21. The filtered and purified fuel flows into the guide tank 2 through the filter 5 and finally flows outward through the discharge outlet 21.

[0029] In addition, a support 3 is provided on the side of the diversion tank 2 to support the device upwards. The support 3 creates a certain storage space between the bottom of the discharge port 21 and the ground, allowing the user to place the fuel storage device in the storage space to collect and store the fuel, or to connect the device to the discharge port 21 via a pipe to transfer the filtered fuel in the diversion tank 2.

[0030] Moreover, referencing Figure 1 and Figure 2 As shown, a base plate 11 is welded to the bottom of the filter tank 1. The flow guide tank 2 is welded to the bottom of the base plate 11. Multiple threaded holes 111 are provided on the base plate 11. The bottom of the filter 5 is locked into the threaded holes 111 to fix the bottom of the filter 5. (Refer to...) Figures 3-5As shown, a fixing plate 6 is sleeved on the upper part of the filter 5 to fix the upper end of the filter 5. Preferably, the fixing plate 6 has a fixing hole 61 that cooperates with the filter 5. The fixing hole 61 is sleeved on the upper end of the filter 5. A rod fixing mechanism 7 is rotatably connected at the center of the fixing plate 6 to fix the installation position of the fixing plate 6.

[0031] The structure of the rod fixing mechanism 7 is as follows: Figures 3-5 As shown, the device includes a fixed sleeve 71 and a fixed shaft 73 slidably disposed inside the fixed sleeve 71. The fixed sleeve 71 has two bosses 72 on its upper part, and the fixed disk 6 is rotatably disposed between the two bosses 72. The fixed shaft 73 has a pull plate 733 at its top, a limiting plate 732 at its bottom, and a triangular connecting claw 731 at its bottom. The fixed sleeve 71 has an inclined wall 711 at its bottom that mates with the sidewall of the triangular connecting claw 731. Under the elastic force of the triangular connecting claw 731, it slides downward along the inclined wall 711, and the limiting plate 732 stops at the upper end of the fixed sleeve 71, thus limiting the extreme position of the downward movement of the triangular connecting claw 731. The chassis 11 has a tapered groove 112 that mates with the triangular connecting claw 731.

[0032] Furthermore, referring to Figure 5 and Figure 6 As shown, a fixing beam 76 is welded to the bottom of the fixing plate 6, and a connecting hole 113 is provided on the base plate 11 to connect with the fixing beam 76, so that the fixing beam 76 is inserted into the connecting hole 113 to prevent the fixing plate 6 from rotating during the process of fixing the filter 5.

[0033] When fixing the upper end of the filter 5, first pull the pull plate 733 upward, so that the triangular connecting claw 731 slides upward along the inclined wall 711. Then, the fixing plate 6 is sleeved on the upper end of the filter 5. At the same time, the bottom of the fixing beam 76 is inserted into the connecting hole 113, and the triangular connecting claw 731 at the bottom of the fixing shaft 73 is inserted into the conical groove 112. Finally, release the pull plate 733. Under its own elastic force, the triangular connecting claw 731 slides along the inclined wall 711 into the conical groove 112. The side wall of the triangular connecting claw 731 and the side wall of the conical groove 112 stop each other, fixing the installation position of the fixing plate 6 so that the fixing plate 6 fixes the upper end of the filter 5.

[0034] Reference Figure 3 and Figure 5As shown, the rod fixing mechanism 7 is externally screwed with a cleaning mechanism 8 for scraping off impurities adhering to the inner wall of the filter tank 1. Specifically, the cleaning mechanism 8 includes a connecting block 84 and a circular spring piece 82. A thread is provided around the outer wall of the fixing sleeve 71 at the bottom of the boss 72. The connecting block 84 is screwed onto the fixing sleeve 71. Multiple connecting ribs 83 are evenly welded to the outside of the connecting block 84. A connecting ring 81 is welded to the end of each connecting rib 83, and a circular spring piece 82 is welded to the end of each connecting ring 81. The circular spring piece 82 forms a sliding connection with the inner wall of the filter tank 1. Furthermore, a groove is vertically formed on the side of the fixing beam 76. A slider is located on one of the connecting ribs 83. This slider is slidably disposed within the groove on the side of the fixing beam 76, allowing the connecting ring 81 to drive the circular spring piece 82 to slide downwards on the inner wall of the filter tank 1, scraping off the impurities adhering to the inner wall of the filter tank 1. A drive ring 74 is also provided at the upper end of the fixing sleeve 71 to drive the fixing sleeve 71 to rotate.

[0035] In use, this fuel filtration and purification device delivers fuel into the filter tank 1 through the inlet 12. The fuel is filtered and purified by the filter 5, then enters the filter 5 and flows into the guide tank 2 through the bottom opening of the filter 5. Finally, it is discharged outward through the outlet 21 at the bottom of the guide tank 2. When cleaning impurities inside the filter tank 1, the drive ring 74 is rotated, which drives the fixed sleeve 71 to rotate on the chassis 11. During the rotation, the fixed sleeve 71 drives the connecting ring 81 to slide vertically downward along the fixed beam 76. At this time, the circular spring 82 slides downward on the inner wall of the filter tank 1, scraping off the impurities attached to the inner wall of the filter tank 1. Finally, the impurities in the filter tank 1 are discharged through the drain port 13. This device eliminates the need for workers to use brushes or other tools to clean the inner side walls of the filter tank 1 when cleaning impurities inside the filter tank 1, reducing the difficulty of cleaning the filter tank 1 and improving the cleaning efficiency of the filter tank 1.
