Description

Technical Field

[0002] As an engine that generates power by burning fuel, the internal combustion engine is one of the most widely used engines in modern industry and transportation. With the advancement of technology, new energy internal combustion engines can achieve low-carbon and zero-carbon emissions, low noise, and high-efficiency operation, effectively solving the problems of high fuel consumption, high emissions, and high noise of old internal combustion engines, thereby gradually replacing old internal combustion engines and becoming a new development trend of internal combustion engines.

[0003] In recent years, ammonia hydrogen internal combustion engine, as a new energy internal combustion engine, uses a mixture of ammonia and hydrogen as fuel, combining the advantages of both fuels to achieve the goal of zero carbon emissions, thus helping to meet the challenges of global climate change and environmental protection. The air filter is an essential component of the intake system of the ammonia hydrogen internal combustion engine. Its main function is to filter out dust and impurities in the air, ensure the cleanliness of the gas entering the internal combustion engine, reduce the wear of various movement-related parts of the internal combustion engine, improve the reliability and durability of the internal combustion engine, thereby extending the service life of the internal combustion engine and reducing the maintenance frequency.

[0004] The existing air filter is mainly composed of an outer shell and a filter element. The filter element is cylindrical. When in use, air enters from the side of the outer shell through the air inlet pipe, and then is filtered by the filter element, so that dust in the air is separated from the filter element or attached to the filter element, and the filtered air is discharged from the outlet pipe connected to the inside of the filter element, thereby improving the cleanliness of the air entering the ammonia hydrogen internal combustion engine, avoiding the "cylinder pulling" phenomenon, and extending the service life of the internal combustion engine.

[0005] However, the existing air filter still has some defects during use: since the air enters from the side wall of the shell, one side of the filter element is always subjected to the instantaneous impact force when the airflow enters, which not only makes this part of the filter element more susceptible to damage than other parts, affecting the service life of the filter element, but also makes this part of the filter element more susceptible to accumulation of dust and impurities than other parts, affecting the filtering effect of the filter element.

[0033] The beneficial effects of the present invention are as follows:

[0034] The present application provides an air filter suitable for a new energy internal combustion engine. A guide mechanism is movably arranged between the filter mechanism and the intake pipe, and the guide mechanism is composed of a guide plate, a guide rail and a cleaning assembly. When the intake pipe takes in air, the guide plate effectively guides the airflow to move circumferentially along the main shell, thereby protecting the side wall of the filter element facing the intake pipe, so that the side wall of the filter element does not have to bear the instantaneous impact force when the airflow enters, thereby preventing the filter element from being damaged and extending the service life of the filter element. At the same time, the guide plate is pushed by the airflow to move toward the filter element, so that the cleaning assembly is inserted into the filter element for cleaning, thereby fully cleaning the dust and impurities attached to the side wall of the filter element, improving the filtering effect and efficiency of the filter element on the air, thereby preventing the outer wall of the filter element from continuously accumulating dust and impurities and causing a decrease in the filtering effect.

[0035] By providing a guide groove on the outer wall of the guide plate and a spiral groove on the guide groove, the air flow blocked by the guide plate is effectively guided, and the air flow is prompted to rotate when moving circumferentially along the main shell body, so that a part of the dust with large mass does not have time to pass through the filter element with the air due to inertia and adheres to the inner wall of the main shell body, which effectively reduces the filtering pressure of the filter element. At the same time, because the cleaning component is movably connected to the guide groove of the guide plate and can swing up and down, when the air flow rotates along the guide groove of the guide plate, the air flow can push the cleaning component to swing up and down, so as to fully clean the outer wall of the filter element, thereby further improving the filtering effect of the air and further extending the service life of the filter element.

[0036] By setting up a filtering mechanism, the filter element is set between the fixed plate and the movable plate, and the filter element is fixed and supported by an external fixing rod and an internal fixing rod, so that the layers of the filter element remain separated, thereby improving the stability of the position and posture of the filter element. This can avoid the problem of reduced filtering effect caused by the adhesion of the filter element due to long-term use, facilitate the disassembly and replacement of the filter element, and prepare for the subsequent self-rotation of the filter element.

[0037] By connecting a movable push plate to the inner wall of the guide plate, and a tooth block is movably provided in the movable push plate, when the guide plate moves toward the direction close to the filter element, the tooth block on the movable push plate engages with the movable column, thereby driving the filter mechanism to rotate as a whole, realizing the change of the position of the side wall of the filter element, so that the cleaning component on the guide plate can clean various positions of the filter element, further improving the filtering efficiency of the filter element; at the same time, by arranging a fixed push plate at the bottom end of the upper sealing cover, and a tooth block is movably provided in the fixed push plate, when the guide plate moves away from the filter element, the tooth block on the fixed push plate engages with the movable column, so that the filter mechanism as a whole does not rotate, effectively ensuring that the filter mechanism rotates only in one direction, further ensuring that various parts of the filter element can be fully cleaned.

The fixed push plate 6 is meshed with the tooth groove of the movable column 26 through the tooth block 7. The size of the connecting groove is larger than that of the tooth block 7, and the right side wall of the connecting groove and the right side wall of the tooth block 7 have the same magnetism. The tooth block 7 can be pushed to a vertical state in the connecting groove through the magnetic repulsion force and meshed with the movable column 26. When the tooth block 7 and the movable column 26 are in a meshing state, the left side wall of the tooth block 7 fits with the left side wall of the connecting groove, and the right side wall of the tooth block 7 does not fit with the right side wall of the connecting groove. At this time, if the movable push plate 5 is pushed to the left When the movable push plate 5 is moved, the movable column 26 will have a counterclockwise rotation force under the action of the movable push plate 5, so that the tooth block 7 in the fixed push plate 6 is pushed and deflected to the right in the connecting groove, so that the tooth block 7 on the fixed push plate 6 does not mesh with the tooth groove of the movable column 26, so as to facilitate the movable push plate 5 to push the movable column 26 to rotate. If the movable push plate 5 is pushed to the right, the tooth block 7 on the fixed push plate 6 is in a vertical state meshed with the movable column 26 and cannot be deflected to the left, so that the movable column 26 cannot rotate clockwise under the thrust of the movable push plate 5. Therefore, when the guide plate 31 moves away from the filter element 24, the tooth block 7 on the fixed push plate 6 meshes with the movable column 26, so that the filter mechanism 2 as a whole does not rotate, effectively ensuring that the filter mechanism 2 only rotates in one direction, and further ensuring that all parts of the filter element 24 can be fully cleaned.

[0065] The working principle of the method of the present invention is as follows:

[0066] When the device is assembled, the filter element 24 is first sleeved on the fixed plate 21, and the lower end of the filter element 24 is fitted with the fixed plate 21. When sleeved, pay attention to the corners of the filter element 24 to be clamped with the outer fixing rod 22 and the inner fixing rod 23 one by one. Then, the movable plate 25 is installed on the top of the outer fixing rod 22 and the inner fixing rod 23, and the upper end of the filter element 24 is fitted with the movable plate 25. In this way, the fixed plate 21, the outer fixing rod 22, the inner fixing rod 23 and the movable plate 25 can fix and support the filter element 24, so that the layers of the filter element 24 are kept separated, the stability of the position and posture of the filter element 24 is improved, and the adhesion of the filter element 24 caused by long-term use can be avoided. The filter element 24 can be easily disassembled and replaced, and the filter element 24 can be prepared for self-rotation. Then, the lower sealing cover 13 is installed at the bottom of the main housing 11, and the guide plate 31 is installed in the main housing 11, and the guide plate 31 is movably engaged with the guide rail 32. The filter mechanism 2 is installed in the main housing 11, and the fixed plate 21 is movably engaged with the lower sealing cover 13. Then, the movable push plate 5 is placed on the movable plate 25, and the movable push plate 5 is connected with the guide plate 31. Finally, the upper sealing cover 12 is installed at the top of the main housing 11 to fix the filter mechanism 2 and the guide mechanism 3, thereby realizing the assembly of the device.

[0067] When air enters the main housing 11 through the air intake pipe 14, since a guide plate 31 is provided between the air intake pipe 14 and the filter mechanism 2, the air flow is blocked by the guide plate 31 and cannot directly face the filter mechanism 2, thereby effectively protecting the side wall of the filter element 24 facing the air intake pipe 14, so that the side wall of the filter element 24 does not need to bear the instantaneous impact force when the air flow enters, thereby preventing the filter element 24 from being damaged and extending the service life of the filter element 24. The blocked air flow moves along the guide groove of the guide plate 31. Since a spiral groove is provided on the guide groove, the air flow is effectively caused to rotate when it moves to both sides of the guide plate 31, so that a part of the dust with a large mass does not have time to pass through the filter element with the air due to inertia. 24 is attached to the inner wall of the main shell 11, which effectively reduces the filtering pressure of the filter element 24. At the same time, due to the thrust of the air flow, the guide plate 31 is approached to the filtering mechanism 2. Since the cleaning component 4 is provided on the guide plate 31, the cleaning component 4 can be inserted into the filter element 24 for cleaning, so that the dust and impurities attached to the side wall of the filter element 24 are fully cleaned, and the filtering effect and efficiency of the filter element 24 on the air are improved, thereby preventing the outer wall of the filter element 24 from continuously accumulating dust and impurities and causing the filtering effect to decrease. In addition, since the air flow on the guide plate 31 performs self-rotation motion, the cleaning component 4 can be pushed to swing up and down, so that the outer wall of the filter element 24 is fully cleaned.

[0068] When the guide plate 31 is acted upon by the wind and approaches the filter mechanism 2, the tooth block 7 on the movable push plate 5 meshes with the movable column 26, thereby driving the filter mechanism 2 to rotate as a whole, thereby changing the position of the side wall of the filter element 24. This not only enables the cleaning component 4 on the guide plate 31 to clean various positions of the filter element 24, thereby further improving the filtration efficiency of the filter element 24, but also changes the position of the filter mechanism 2, so that the filter mechanism 2 will not stay in the same position for a long time, thereby increasing the service life of the filter mechanism 2. When the guide plate 31 is acted upon by the spring and approaches the intake pipe 14, the tooth block 7 on the fixed push plate 6 meshes with the movable column 26, thereby moving the movable push plate 5 but not rotating the filter mechanism 2 as a whole, thereby effectively ensuring that the filter mechanism 2 rotates only in one direction, thereby further ensuring that various parts of the filter element 24 can be fully cleaned.
