Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, and in particular to a fuel tank that prevents clogging. Background Technology

[0002] Diesel fuel tanks are containers used to store diesel fuel and are widely used in various diesel-powered equipment and vehicles, such as automobiles, trucks, ships, and generator sets. The design and manufacture of diesel fuel tanks require consideration of multiple factors, including material selection, structural design, corrosion resistance, sealing performance, and safety.

[0003] In the prior art, patent publication number CN214513051U discloses an oil tank filtration device for preventing clogging, including an oil tank body with an anti-clogging mechanism inside. The anti-clogging mechanism includes a motor protective cover, a motor, a motor shaft, a first rotating rod, a first gear, a fixing plate, a second gear, a second rotating rod, a stirring rod, and oil pipes. The motor protective cover is bolted to the top center of the oil tank body, and the motor is bolted to the top of the inside of the motor protective cover. The motor shaft is rotatably connected to the bottom of the motor. This invention, through the first gear on the first rotating rod and the second rotating rod and stirring rod inside the second gear, not only allows the first gear to drive the second gear to rotate, and the second gear to drive the two second rotating rods and stirring rods to rotate, but also actively stirs within the four oil pipes, actively cleaning blockages in the oil pipes. Furthermore, when multiple oil pipes are provided, if one oil pipe is blocked, the other oil pipes can be opened for use.

[0004] Although the above-mentioned fuel tank can achieve the effect of cleaning the inner wall of the fuel tank through the motor, the first rotating rod, the first gear and the fixed plate, it still has the following shortcomings in practical application: when diesel is poured into the fuel tank, impurities in the diesel enter the fuel tank along with it and cannot be filtered. In addition, diesel impurities are very easy to adhere to the inner wall of the fuel pipe, which can easily lead to blockage after long-term use. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an oil tank that prevents clogging.

[0006] To achieve this objective, the present invention adopts the following technical solution: an oil tank for preventing blockage, comprising an oil tank body, a primary filter assembly fixedly installed on the top of the oil tank body, the primary filter assembly comprising a filter box fixedly installed on the top of the oil tank body, an oil injection pipe fixedly inserted into the top wall of the filter box, a connecting pipe fixedly inserted into the bottom wall of the filter box and the top wall of the oil tank body, and a secondary filter assembly fixedly inserted into the side wall of the oil tank body, the secondary filter assembly comprising an oil delivery pipe fixedly inserted into the side wall of the oil tank body, and a collection assembly fixedly installed at the bottom of the oil delivery pipe.

[0007] Preferably, a liquid pump is fixedly installed on the top of the oil tank body, and the input end and output end of the liquid pump are respectively connected to the side wall of the oil tank body and the top of the filter box.

[0008] Preferably, a filter drawer is slidably installed on the front of the filter box, and a filter screen plate is fixedly sleeved on the inner ring of the bottom wall of the filter drawer.

[0009] Preferably, a fixing frame and a filter screen are fixedly installed inside the oil pipeline. A fixing shaft is fixedly installed on the side of the fixing frame near the filter screen. The fixing shaft is located on the central axis of the oil pipeline, and the outer wall of the oil pipeline is fixedly connected to the filter screen. A rotating cylinder is rotatably sleeved around the fixing shaft, and a sleeve is fixedly installed at the end of the fixing shaft away from the fixing frame.

[0010] Preferably, multiple spiral blades are uniformly fixedly installed on the periphery of the rotating drum, and the spiral blades all abut against the inner wall of the oil pipeline. A cleaning brush is fixedly installed on the side of the spiral blades near the filter screen, and the cleaning brush abuts against the filter screen.

[0011] Preferably, the collection assembly includes a collection box fixedly installed at the bottom of the oil pipeline, and the bottom of the oil pipeline has an opening located directly below the cleaning brush.

[0012] Preferably, the collection box has an observation window fixedly fitted on the inner ring of the front side, a door hinged to the bottom of the collection box, and a sealing gasket at the connection between the top of the door and the bottom of the collection box.

[0013] The beneficial effects of this invention are as follows: When using this device, diesel fuel is injected into the fuel tank through the injection pipe. The diesel fuel first enters the filter box and is filtered by the filter screen, preventing impurities in the diesel fuel from entering the fuel tank. Periodically activating the pump extracts diesel fuel from the fuel tank and injects it into the filter box from the top. As the diesel fuel enters the filter box, impurities are filtered and intercepted by the filter screen and stored inside the filter drawer. Through these features, the device can filter the diesel fuel entering the fuel tank and automatically filter it periodically, reducing the sedimentation of impurities in the fuel tank. Diesel fuel is output to the outside through the fuel delivery pipe. As the diesel fuel passes through the fuel delivery pipe, it is pushed... Multiple spiral blades rotate, continuously cleaning the inner wall of the oil pipeline to prevent diesel impurities from adhering and clogging. A cleaning brush rotates along with the spiral blades, continuously removing impurities filtered onto it. The diesel impurities cleaned by the spiral blades and cleaning brush enter the collection box through a port, preventing accumulation and blockage inside the oil pipeline. Users can observe the collection box's impurity collection status through an observation window for timely cleaning. Opening the box door allows for the removal of impurities. These features enable the device to automatically clean the inner wall of the oil pipeline and the filter screen, preventing blockages. Attached Figure Description

[0023] like Figure 1-3 As shown, the present invention proposes an anti-clogging fuel tank, comprising a fuel tank body 1, a primary filter assembly 2 fixedly installed on the top of the fuel tank body 1, the primary filter assembly 2 comprising a filter box 22 fixedly installed on the top of the fuel tank body 1, an oil injection pipe 5 fixedly inserted into the top wall of the filter box 22, a connecting pipe 25 fixedly inserted into the bottom wall of the filter box 22 and the top wall of the fuel tank body 1, and a secondary filter assembly 3 fixedly inserted into the side wall of the fuel tank body 1, the secondary filter assembly 3 comprising an oil delivery pipe 31 fixedly inserted into the side wall of the fuel tank body 1, and a collection assembly 4 fixedly installed at the bottom of the oil delivery pipe 31.

[0024] In this embodiment: A liquid pump 21 is fixedly installed on the top of the fuel tank body 1. The input end and output end of the liquid pump 21 are connected to the side wall of the fuel tank body 1 and the top of the filter box 22, respectively. With this setting, the liquid pump 21 can be started periodically to extract diesel fuel from the fuel tank body 1 and inject it into the filter box 22 from the top. A filter drawer 23 is slidably installed on the front of the filter box 22. A filter screen plate 24 is fixedly sleeved on the inner ring of the bottom wall of the filter drawer 23. With this setting, when the diesel fuel injected into the filter box 22 passes through the filter screen plate 24, the impurities inside the diesel fuel will be filtered and intercepted by the filter screen plate 24 and stored inside the filter drawer 23.

[0025] Example 2

[0026] like Figure 1-3As shown, the present invention proposes an anti-clogging oil tank. Compared with Embodiment 1, this embodiment further includes a fixing frame 32 and a filter screen 33 fixedly installed inside the oil delivery pipe 31. A fixing shaft 34 is fixedly installed on the side of the fixing frame 32 near the filter screen 33. The fixing shaft 34 is located on the central axis of the oil delivery pipe 31, and the outer wall of the oil delivery pipe 31 is fixedly connected to the filter screen 33. A rotating cylinder 35 is rotatably sleeved around the fixing shaft 34. A sleeve head 38 is fixedly installed at the end of the fixing shaft 34 away from the fixing frame 32. Through this arrangement, the fixing shaft 34 passes through the fixing frame... The filter 32 is fixed on the central axis of the oil pipe 31. The rotating drum 35 can rotate around the fixed shaft 34. The filter screen 33 can filter the diesel fuel passing through the oil pipe 31. The sleeve 38 acts as a guide. Multiple spiral blades 36 are evenly fixedly installed on the outer periphery of the rotating drum 35, and the spiral blades 36 all abut against the inner wall of the oil pipe 31. Cleaning brushes 37 are fixedly installed on the side of the spiral blades 36 near the filter screen 33, and the cleaning brushes 37 all abut against the filter screen 33. Through this arrangement, when the diesel fuel passes through the oil pipe 31, it will drive the multiple spiral blades 36 to rotate. As the spiral blade 36 rotates, it continuously cleans the inner wall of the oil delivery pipe 31, preventing diesel impurities from adhering to the inner wall and thus avoiding blockage. The cleaning brush 37 rotates along with the spiral blade 36, continuously cleaning the impurities filtered on it. The collection assembly 4 includes a collection box 41 fixedly installed at the bottom of the oil delivery pipe 31. The bottom of the oil delivery pipe 31 has an opening 42, which is located directly below the cleaning brush 37. This arrangement allows the diesel impurities cleaned by the spiral blade 36 and the cleaning brush 37 to pass through. The oil enters the collection box 41 through the opening 42, thus preventing impurities from accumulating inside the oil pipe 31 and causing blockage. An observation window 43 is fixedly fitted on the inner ring of the front of the collection box 41. A box door 44 is hinged to the bottom of the collection box 41. Sealing gaskets are provided at the connection between the top of the box door 44 and the bottom of the collection box 41. This setting allows the user to observe the collection of impurities inside the collection box 41 through the observation window 43, making it convenient for the user to clean the impurities collected inside the collection box 41 in a timely manner. The impurities inside the collection box 41 can be processed by opening the box door 44.

[0027] Working principle: When using this device, diesel fuel is injected into the fuel tank body 1 through the fuel injection pipe 5. The diesel fuel first enters the filter box 22 and is filtered by the filter screen plate 24 to prevent impurities in the diesel fuel from entering the fuel tank body 1. The pump 21 is periodically started to extract the diesel fuel from the fuel tank body 1 and inject it into the filter box 22 from the top. When the diesel fuel injected into the filter box 22 passes through the filter screen plate 24, the impurities in the diesel fuel are filtered and intercepted by the filter screen plate 24 and stored inside the filter drawer 23. The diesel fuel is output to the outside through the fuel delivery pipe 31. When the diesel fuel passes through the fuel delivery pipe 31, it will drive multiple spiral blades 36 to rotate. The rotation of the spiral blades 36 The inner wall of the oil pipe 31 is constantly cleaned to prevent diesel impurities from adhering to it and thus avoid clogging. The cleaning brush 37 rotates with the rotation of the spiral blade 36, thereby continuously cleaning the impurities filtered on the cleaning brush 37. The diesel impurities cleaned by the spiral blade 36 and the cleaning brush 37 enter the collection box 41 through the inlet 42, thus preventing impurities from accumulating inside the oil pipe 31 and causing clogging. The user can observe the impurity collection inside the collection box 41 through the observation window 43, which allows the user to clean the impurities collected inside the collection box 41 in a timely manner. The impurities inside the collection box 41 can be processed by opening the box door 44.
