Description

Technical Field

[0001] This utility model relates to the field of air filter technology, and in particular to an engine air filtration device. Background Technology

[0002] As a core component of a vehicle, the engine's performance not only directly affects the car's power output and fuel economy, but also greatly influences exhaust emission levels, thus impacting the environment.

[0003] When the vehicle's operating environment is dusty, the untreated air it draws in may contain solid particles such as dust and sand. If these impurities enter the engine, they will accelerate component wear and shorten engine life. Filtering the air entering the engine's combustion chamber ensures complete fuel combustion, thereby improving engine thermal efficiency and reducing fuel consumption. Therefore, ensuring that the air entering the engine's combustion chamber is pure and free of impurities is crucial for improving engine efficiency and reducing harmful emissions.

[0004] In existing engine air filtration systems, the filter element is often exposed at the air intake. If the vehicle operates in rainy or high-humidity environments, rainwater can enter the air filter element through the intake vents, causing it to become wet. This not only reduces the filter's filtration efficiency but can also obstruct engine airflow, affecting the vehicle's normal operation. Therefore, designing an air filtration system that effectively prevents rainwater from entering is crucial. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an engine air filtration device.

[0006] To achieve the above objectives, this utility model provides an engine air filtration device, including a housing, a filter unit, and a barrier unit. The housing includes at least two mounting cylinders, each with a mounting cavity that is connected to the first mounting cylinder. The first mounting cylinder has an air inlet, and the second mounting cylinder has an air outlet. The filter unit includes a filter element, which is installed in the mounting cavity of the mounting cylinder. The barrier unit is fixedly connected to the first mounting cylinder and installed between the air inlet and the filter element.

[0007] Furthermore, the blocking unit is a circular ring plate, and the height of the upper side of the circular ring plate, which is perpendicular to its axis, is higher than the highest point of the air inlet.

[0008] Furthermore, the air filtration device also includes a safety alarm unit, which includes a differential pressure alarm and a controller. The differential pressure alarm is installed at the air outlet and is electrically connected to the controller.

[0009] Furthermore, the air filtration device is also equipped with an automatic cleaning unit, which includes a vibration mechanism disposed on the inner wall of the first mounting cylinder, the vibration mechanism being in contact with the inner wall of the first mounting cylinder.

[0010] Furthermore, the vibration mechanism includes an annular support and at least two electromagnetic vibrators. The annular support is fixedly installed on the inner wall of the first mounting cylinder, and the electromagnetic vibrators are evenly distributed along the circumference of the annular support.

[0011] Furthermore, the engine air filtration device also includes multiple dust discharge ports, which are evenly distributed around the axis of the first mounting cylinder at the bottom of the first mounting cylinder and located on the outside of the filter core inside the first mounting cylinder.

[0012] Furthermore, the air filtration device also includes a dust collection box, which is installed at the bottom of the first mounting cylinder and detachably connected to the first mounting cylinder.

[0013] Furthermore, the outer surface of the dust collection box is provided with a handle and a transparent observation window, and the inner wall is provided with an anti-static coating.

[0014] Furthermore, the bottom of the dust collection box is provided with a discharge hole, and a one-way baffle is provided at the discharge hole. The one-way baffle is hinged to the dust collection box and installed inside the dust collection box.

[0015] Furthermore, the dust collection box is equipped with a material level sensor, which is electrically connected to the controller.

[0016] The beneficial effects of this utility model are:

[0017] 1. By installing a barrier unit between the filter element and the air intake, rainwater is prevented from entering through the air intake and wetting the filter element during vehicle use. This extends the filter element's lifespan and improves the stability and reliability of the vehicle's air intake system. Simultaneously, the design of this barrier unit also considers airflow efficiency, ensuring that while blocking rainwater, it does not affect the vehicle's normal air intake requirements.

[0018] 2. By installing a differential pressure alarm at the air outlet, the resistance change of the filter element can be monitored in real time. Once the differential pressure alarm detects that the resistance exceeds the preset threshold, it will immediately issue an alarm to remind the driver or maintenance personnel to replace or clean the filter element in time, thus preventing engine failure caused by filter element blockage, thereby extending the service life of the vehicle and improving overall operating efficiency.

[0019] 3. By incorporating an automatic cleaning unit, the filter element inside the first mounting cylinder can be automatically cleaned, effectively preventing clogging caused by dust or particles accumulating on the filter element's surface and extending its service life. Simultaneously, this automatic cleaning unit, in conjunction with the dust outlet and dust collection box, can collect the dust or particles filtered by the filter element, reducing the maintenance costs of the air filtration equipment.

[0031] This utility model discloses an engine air filtration device. (See attached diagram.) Figure 1The engine air filtration device includes a housing 100, a filter unit, and a barrier unit 200. The housing 100 includes at least two mounting cylinders 101, each with a mounting cavity, and the two mounting cavities are connected. The first mounting cylinder 111 has an air inlet 301 on its outer side, and the second mounting cylinder 112 has an air outlet 302. The filter unit includes a filter element 300, which is installed in the mounting cavity of the mounting cylinder 101. The gas to be filtered passes through the air inlet 301, is filtered by the filter element 300, and is discharged through the air outlet 302. The barrier unit 200 is fixedly connected to the first mounting cylinder 111 and is installed between the air inlet 301 and the filter element 300.

[0032] The engine air filtration device of this utility model is particularly suitable for special vehicles such as coal pan cars. Coal pan cars often operate in high-dust and high-humidity coal mine environments. By setting a barrier unit 200 between the filter element 300 and the air inlet 301, it can effectively intercept coal dust, rainwater and large particulate pollutants from directly contacting the filter element 300. This avoids problems such as pore blockage and fiber expansion caused by local water absorption in the filter element 300, and extends the service life of the filter element 300. It also reduces the sudden change in air resistance caused by local moisture in the filter element 300, stabilizes the intake airflow and air-fuel ratio of the vehicle engine, reduces the risk of power fluctuations or incomplete combustion, and improves the environmental tolerance of the intake system.

[0033] The working process of this engine air filtration device is as follows: the gas to be filtered enters the first mounting cylinder 111 through the air inlet 301, is filtered by the filter element 300 in the first mounting cylinder 111, and then enters the second mounting cylinder 112. After being filtered again, it is discharged through the air outlet 302. The engine air filtration device provided by this utility model, by setting at least two mounting cylinders 101 for mounting the filter element 300, ensures that the gas to be filtered can fully contact the filter material, thereby improving the filtration efficiency of the filter element 300.

[0034] In one embodiment of this utility model, the blocking unit 200 is a circular ring plate, and the height of the upper side of the circular ring plate perpendicular to its axis is higher than the highest point of the air inlet 301. For example... Figure 1 , Figure 2 As shown, the air intake 301 is located on the side wall of the first mounting cylinder 111 near the bottom. The annular plate is fixedly installed at the bottom of the first mounting cylinder 111, and the axis of the annular plate is collinear with the axis of the first mounting cylinder 111. A gap is left between the outer edge of the annular plate and the inner wall of the first mounting cylinder 111 to ensure that air can smoothly enter the interior of the first mounting cylinder 111 through the air intake 301. The upper side of the annular plate, which is perpendicular to its axis, is higher than the highest point of the air intake 301. Thus, the annular plate can prevent rainwater from entering through the air intake 301 and wetting the filter element 300, while not affecting the normal air intake requirements of the vehicle, thus ensuring the air intake efficiency of the engine.

[0035] In a preferred embodiment of the present invention, the engine air filtration device further includes a safety alarm unit, which includes a differential pressure alarm 400. The differential pressure alarm 400 can monitor the air pressure data in the mounting cavity and is electrically connected to a controller (not shown).

[0036] This engine air filter has an automatic detection function, which can monitor the pressure changes on both sides of the filter element 300 in real time. Users can preset the differential pressure value of the air filter. When the differential pressure alarm 400 detects that the differential pressure exceeds the preset threshold or safety value, it will immediately issue an alarm to remind the driver or maintenance personnel to replace the filter element 300 in time, ensuring that the filtration effect is always in the best condition. This prevents engine failure caused by the clogging of the filter element 300, thereby extending the service life of the vehicle and improving the overall operating efficiency.

[0037] In a preferred embodiment of the present invention, the air filtration device is further provided with an automatic cleaning unit. The automatic cleaning unit includes a vibration mechanism 500 disposed on the inner wall of the first mounting cylinder 111. The vibration mechanism 500 is in contact with the inner wall of the first mounting cylinder 111. The vibration mechanism 500 includes an annular bracket 501 and at least two electromagnetic vibrators 502. The annular bracket 501 is spirally fixedly installed on the inner wall of the first mounting cylinder 111. The electromagnetic vibrators 502 are evenly distributed circumferentially along the inner wall of the first mounting cylinder 111.

[0038] By incorporating an automatic cleaning unit, the filter element 300 inside the first mounting cylinder 111 can be automatically cleaned, preventing clogging caused by dust or particles accumulating on the surface of the filter element 300, extending its service life, and effectively improving the filtration capacity of the air filtration equipment. Specifically, for example... Figure 3 As shown, before the air filtration device stops operating after a certain period of time, the vibration mechanism 500, upon receiving a signal from the controller, activates the electromagnetic vibrator 502 to vibrate the inner wall of the first mounting cylinder 111. Since the cover 102 is locked to the first mounting cylinder 111, the filter core 300 will not shift relative to the first mounting cylinder 111 or the cover 102. The vibration of the inner wall of the first mounting cylinder 111 is transmitted to the filter core 300 through the cover 102 and itself, causing it to vibrate and dislodging dust or particles blocked on the outside of the filter core 300. Furthermore, by providing an annular support 501 on the inner wall of the first mounting cylinder 111, the electromagnetic vibrator 502 is evenly and fixedly installed on the annular support 501, covering a larger vibration area and avoiding cleaning dead zones caused by a single vibration point.

[0039] It should be noted that in another embodiment of this utility model, the automatic cleaning unit is a back-blowing component. The air outlet of the back-blowing component extends into the filter core 300 inside the first mounting cylinder 111. The back-blowing component can back-blow the filter core 300 to remove dust adhering to the outside of the filter core 300. This back-blowing function can be achieved by existing technical means, so the back-blowing component will not be described in detail.

[0040] In a preferred embodiment of this utility model, the engine air filtration device further includes dust discharge ports (not shown). These dust discharge ports are evenly distributed around the axis of the first mounting cylinder 111 at the bottom of the first mounting cylinder 111 and are located on the outer side of the filter element 300 inside the first mounting cylinder 111. By evenly distributing the dust discharge ports at the bottom of the first mounting cylinder 111, when the automatic cleaning unit automatically cleans the filter element 300 of the first mounting cylinder 111, it helps to promptly discharge the dust accumulated on the surface of the filter element 300, preventing it from being re-inhaled into the engine and ensuring the filtration effect of the air filtration device.

[0041] Furthermore, the number of dust discharge ports can be set according to actual needs, such as six, eight or more, to ensure that the dust adhering to the surface of the filter core 300 can be smoothly discharged from the first mounting cylinder 111.

[0042] In a preferred embodiment of this utility model, the air filtration device further includes a dust collection box 700, which is installed at the bottom of the first mounting cylinder 111 and detachably connected to the first mounting cylinder 111. Figure 1 , Figure 2 As shown, by setting up the dust collection box 700, dust or particles discharged from the dust outlet can be effectively collected, avoiding secondary pollution from dust and facilitating cleaning and maintenance for users. Furthermore, by making the dust collection box 700 and the first mounting cylinder 111 detachably connected, users can easily disassemble the dust collection box 700 to empty or further process the dust, making replacement and cleaning of the dust collection box 700 more convenient and improving the ease of use and maintainability of the equipment. This ensures the continuous and efficient operation of the air filtration equipment.

[0043] It should be noted that the present invention does not limit the connection method between the dust collection box 700 and the first mounting cylinder 111. In one embodiment, the dust collection box 700 and the first mounting cylinder 111 can be connected by a snap-fit. In another embodiment, the dust collection box 700 and the first mounting cylinder 111 can be fixedly connected by bolts.

[0044] In a preferred embodiment of the present invention, the dust collection box 700 has a handle 701 and a transparent observation window 702 on its outer surface, and an antistatic coating on its inner wall.

[0045] like Figure 1 , Figure 4 As shown, the handle 701 on the outer surface of the dust collection box 700 makes it easier for users to grip when disassembling and installing it, improving operational convenience. The transparent observation window 702 allows users to visually observe the dust accumulation inside the dust collection box 700 without opening it, enabling timely cleaning and preventing excessive dust buildup from affecting the air filtration effect. Furthermore, the anti-static coating on the inner wall effectively prevents dust from adhering to the inner wall of the dust collection box 700, further improving dust collection efficiency and reducing cleaning difficulty, making equipment maintenance simpler and more efficient.

[0046] In a preferred embodiment of the present invention, the bottom of the dust collection box 700 is provided with a discharge hole 703, and a one-way baffle 800 is provided at the discharge hole 703. The one-way baffle 800 is hinged to the dust collection box 700 and installed inside the dust collection box 700.

[0047] like Figure 4 As shown, by designing a one-way baffle 800, external air or impurities cannot enter the dust collection box 700, effectively preventing dust leakage during disassembly or transportation, and maintaining the cleanliness and filtration effect of the equipment. At the same time, the hinged design of the one-way baffle 800 and the dust collection box 700 means that when the user cleans the dust in the dust collection box 700, they only need to open the one-way baffle 800 relative to the dust collection box, avoiding the problem of dust leakage, further improving the reliability and durability of the equipment, and ensuring the efficient and stable operation of the air filtration equipment in various operating environments.

[0048] In a preferred embodiment of this invention, a level sensor 900 is provided inside the dust collection box 700. The level sensor 900 is connected to the controller and triggers an audible and visual alarm when the dust accumulation reaches a set threshold. In this embodiment, the material sensor, photoelectric alarm device, and controller are electrically connected. The level sensor 900 allows for real-time monitoring of dust accumulation in the dust collection box 700. Once the dust accumulates to a preset height threshold, the sensor immediately sends a signal to the controller. Upon receiving the signal, the controller triggers the audible and visual alarm device (not shown), promptly informing the user that the dust collection box 700 needs cleaning through both sound and light alerts. The level sensor 900 and the audible and visual alarm device greatly simplify the user's operation and improve the timeliness of equipment maintenance.

[0049] It should be noted that this utility model does not limit the type of material level sensor 900 and photoelectric alarm device, so it will not be described in detail.

[0050] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
