Description

Technical Field

[0001] The invention relates to the technical field of diesel filters, in particular to a diesel filter assembly. Background Art

[0002] With the rapid development of the automobile industry, diesel engines are widely used in various types of vehicles due to their advantages such as high efficiency and durability. As one of the key components of the diesel engine fuel system, the diesel filter mainly filters impurities, moisture and pollutants in the diesel to ensure the normal operation of the fuel system and the performance of the engine. However, the existing diesel filter assembly still has some problems and shortcomings in actual use. The existing diesel filter is generally composed of a shell and a filter element. The diesel in the fuel supply pipe is transported to the shell, and the impurities and moisture in the diesel are separated by the filter element arranged in the shell. A large diesel filter on one side will also be specially provided with an oil-water separator to facilitate the thorough separation of moisture in the diesel. Therefore, the diesel filter improves the service life of the engine and reduces the loss of the engine by separating the impurities and moisture in the diesel.

[0003] The existing Chinese patent with publication number CN116220978A includes a cylinder, a filter cartridge arranged inside the cylinder, a connecting seat installed at the upper end of the cylinder, a mounting rib fixed at the rear end of the connecting seat, a pump body installed at the upper end of the connecting seat and a bottom cup installed at the lower end of the cylinder, two electric heating rings distributed in concentric circles are installed on the inner side of the connecting seat, an oil passage is arranged between the connecting seat, the pump body and the cylinder, a drain valve and an electric heating pipe are respectively installed at the lower end of the bottom cup, an oil passage regulating mechanism for diesel flow path control is arranged between the cylinder and the bottom cup, and an electric control unit for monitoring and controlling the temperature and pressure of the connecting seat and the cylinder flow wall is arranged on the connecting seat.

[0004] When the above device is in use, when the temperature of the diesel pumped into the connecting seat through the pump body is too low or the circulation pressure is too high, the energized coil outside the soft iron core can be energized, and the soft iron core will generate electromagnetic force. Under the magnetic attraction between the soft iron core and the magnetic block, the valve disc is pushed downward to separate from the fixed disc. At this time, the diesel is preliminarily heated by the electric heating ring. However, in actual use, due to changes in the vehicle's driving speed and driving gear, as the engine's demand for diesel increases, a large amount of diesel will flow into the diesel filter in a short period of time, increasing the requirements for the filtering amount of the filter element. Impurities can easily cause blockage of the filter element, resulting in insufficient or interrupted fuel supply, affecting the normal driving of the vehicle. Therefore, it is difficult to automatically adjust the dynamic flow rate of the filter element according to the amount of diesel required by the engine.

[0005] For this purpose, we propose a diesel filter assembly. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up an adjustment mechanism, the dynamic flow rate of the filter element can be automatically adjusted according to the amount of diesel required by the engine. When the engine's demand for diesel increases, the lifting cylinder automatically descends under the action of pressure, increasing the filtration area of ​​the filter paper, thereby increasing the filtration flow rate; when the demand decreases, the lifting cylinder resets under the action of the spring, reducing the filtration area and the flow rate, effectively solving the problems of filter element clogging and insufficient fuel supply caused by fixed flow in traditional filters, ensuring the stable operation of the engine under different working conditions.

[0017] Second, the triangular grooves and triangular blocks in the cleaning mechanism can scrape off impurities on the surface of the filter paper, realizing automatic cleaning of impurities on the surface of the filter paper. The triangular grooves and triangular blocks can support the folds of the filter paper, ensuring the distance between each fold of the filter paper, avoiding deformation of the filter paper under the flow impact of diesel, and further improving the filtering effect of the filter paper; The impurities are transferred to the slag discharge pipe and discharged into the collection tank through the gear ring and material transfer plate in the collection mechanism, which not only prolongs the service life of the filter element and reduces the maintenance frequency, but also avoids the influence of impurity accumulation on the filtering effect.

[0018] 3. By setting up electric heating tubes and temperature sensors, the diesel temperature inside the filter cartridge can be monitored and heated in real time. When the temperature sensor detects that the diesel temperature is too low, the external controller will automatically start the electric heating tube to heat the diesel to ensure the fluidity of the diesel in a low temperature environment, thereby improving the cold start performance of the engine and effectively solving the problem of performance degradation of traditional filters in a low temperature environment.

[0019] 4. Automatic separation and discharge of water in diesel is achieved through the separation mechanism and liquid level monitoring system. The drainage holes and sealing blocks in the separation mechanism can be opened and closed periodically under the push of the gear ring to discharge the water into the bottom cup; the liquid level sensor monitors the water level in the bottom cup in real time. When the water level is too high, it automatically alarms and prompts discharge, effectively preventing water from entering the engine combustion chamber and improving the combustion efficiency and service life of the engine.

[0020] The coordinated use of the above-mentioned structure solves the problem that, in actual use of the existing device, as the vehicle's driving speed and driving gear change, as the engine's demand for diesel increases, a large amount of diesel will flow into the diesel filter in a short period of time, increasing the requirement for the filter element's filtration capacity, impurities can easily cause clogging of the filter element, resulting in insufficient or interrupted fuel supply, affecting the normal driving of the vehicle, and therefore it is difficult to automatically adjust the dynamic flow rate of the filter element filtration according to the amount of diesel required by the engine.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0024] See also Figures 1 to 9 The present invention provides a technical solution: a diesel filter assembly comprises a cylinder 1, the end of the cylinder 1 is fixedly connected with a mounting rib 2 for supporting the cylinder 1, and the inner wall of the end of the cylinder 1 is fixedly connected with a liquid inlet end cover 3, the bottom of the liquid inlet end cover 3 is fixedly connected with a filter cartridge 7, the outer contour of the filter cartridge 7 is fixedly connected with a filter paper 701 for filtering impurities in diesel, and the end of the filter cartridge 7 is penetrated and fixedly connected with a main oil pipe 8 connected with the port of the liquid inlet end cover 3, one side of the mounting rib 2 is penetrated and fixedly connected with a liquid inlet pipe 4 for conveying diesel to the inside of the cylinder 1, the end of the liquid inlet end cover 3 is penetrated and fixedly connected with a drain pipe 5 for discharging diesel at a symmetrical position away from the liquid inlet pipe 4, and the outlet end of the drain pipe 5 is penetrated to the outside of the mounting rib 2 and fixedly connected, the mounting rib 2 is fixedly connected with an oil pump 6 for conveying diesel, and the cylinder 1 is provided with an adjusting mechanism for adjusting the dynamic flow rate filtered by the filter paper 701.

[0025] When in use, by setting the cylinder 1 and the mounting ribs 2 arranged on the cylinder 1, the mounting ribs 2 can support the cylinder 1 to improve the stability of the cylinder 1, and by the liquid inlet end cover 3 arranged on the cylinder 1, the liquid inlet end cover 3 is fixedly supported on the inner wall of the cylinder 1, and by the filter cartridge 7 arranged on the liquid inlet end cover 3 and the filter paper 701 arranged on the filter cartridge 7, the filter cartridge 7 can drive the filter paper 701 to be fixedly supported on the bottom end of the liquid inlet end cover 3, so as to facilitate the subsequent filtering of impurities and moisture in the diesel, and by the liquid inlet pipe 4 and the liquid discharge pipe 5 arranged on the mounting ribs 2 and the liquid inlet end cover 3, the liquid inlet pipe 4 and the liquid discharge pipe 5 can be fixedly supported on the mounting ribs 2 and the liquid inlet end cover 3 respectively.

[0026] By installing the oil pump 6 set on the rib plate 2, during use, when the oil pump 6 starts to work and negative pressure is generated in the liquid inlet pipe 4, the liquid inlet pipe 4 can draw diesel to the liquid inlet end cover 3, so that the diesel can evenly enter the inner wall of the cylinder 1 through the through holes on the liquid inlet end cover 3. When the diesel contacts the filter paper 701, the filter paper 701 can filter impurities in the diesel, and the filtered diesel can enter the interior of the filter cartridge 7. Due to the large density of water, the filter paper 701 can separate the moisture in the diesel, so that the moisture can be deposited at the bottom, through the main oil pipe 8 set on the filter cartridge 7, and the main oil pipe 8 is fixedly supported, then the diesel at the bottom of the filter cartridge 7 can be discharged through the main oil pipe 8.

[0027] Through the adjustment mechanism arranged on the cylinder 1, the adjustment mechanism can automatically adjust the dynamic flow rate filtered by the filter paper 701 according to the amount of diesel required by the engine. Embodiment 2:

[0028] On the basis of the first embodiment, further: The regulating mechanism includes a circular plate 9 fixedly connected to the inner wall of the cylinder 1 near the bottom end, a cylindrical shell 10 penetrated and fixedly connected to the circular plate 9, and the end of the cylindrical shell 10 penetrates the inner wall of the filter cartridge 7 and is fixedly connected, a lifting cylinder 11 for adjusting the dynamic flow rate of the filter paper 701 is connected to the cylindrical shell 10 for lifting and moving, and the lifting cylinder 11 is sleeved on the outer contour of the bottom of the filter paper 701 and movably connected, and a first spring 12 for guiding the lifting cylinder 11 to reset and move is fixedly connected to the bottom end of the lifting cylinder 11 and the opposite surface to the circular plate 9.

When the diesel temperature is too low, the external controller starts the electric heating tube 13 to heat the diesel inside the filter cartridge 7. The above-mentioned temperature sensor 14 converts the detected value of the diesel temperature into an electrical signal and transmits it remotely to the external controller, which is a prior art, so it will not be repeated here.

As the lifting cylinder 11 moves in a downward vertical direction, the first spring 12 can be squeezed and contracted under the action of the lifting cylinder 11. When the demand for diesel by the engine decreases, the pressure inside the cylinder body 1 decreases accordingly. Then, the first spring 12 can push the lifting cylinder 11 to reset in an upward vertical direction under the action of elastic force, thereby reducing the dynamic flow rate of diesel filtered by the filter paper 701, thereby realizing automatic adjustment of the dynamic flow rate filtered by the filter paper 701 according to the amount of diesel required by the engine.
