Description

Technical Field

[0001] The utility model relates to an air intake filter device, in particular to an engine air intake filter device for heavy vehicles. Background Art

[0002] At present, the air intakes of heavy-duty vehicle engines are mostly equipped with air intake filtration devices, namely air filters, which are mainly used in the engine intake system to filter impurities in the air filter entering the engine, ensuring that the air entering the engine is clean and preventing impurities from entering the engine. This can further prevent the pistons, piston rings, valves and other moving parts in the engine from wearing out and failing due to impurities, directly affecting the reliability of the engine operation.

In work areas with strong winds and sand or poor air cleanliness, the filter element is very easy to be clogged, which will directly affect the filtration performance of the air filtration device. During use, the engine is prone to serious faults such as cylinder scuffing and high oil consumption. Utility Model Content

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model includes a shell, and a primary air intake filter assembly, a secondary air guide filter assembly and a gas outlet assembly which are sequentially arranged in the shell from right to left. This arrangement allows the gas entering the engine to be filtered in a primary single-stage manner in the primary air intake filter assembly, filtered in a secondary multi-stage manner in the secondary air guide filter assembly, and finally exported to the outside of the shell through the gas outlet assembly. Compared with the previous air intake filter device, this air intake filter device adopts a multi-stage filtering method with higher filtering efficiency. The entire filter channel is arranged in a straight line, and the air intake is smoother. The primary air intake filter assembly includes an air intake pipe, the right end of the air intake pipe is connected to the right side of the shell and extends to the outside of the shell, the left end of the air intake pipe is correspondingly provided with a primary filter screen, and the left end of the air intake pipe is connected to the left corresponding to the primary filter screen and is provided with a primary air filter channel.

After the initial filtration, the air is introduced into the secondary air filter assembly through the primary air filter channel. The entire path is "straight", which can achieve rapid air intake and effectively intercept larger particles in the gas, effectively reducing the filtration pressure of the secondary air filter assembly while also improving the filtration efficiency to a certain extent; the secondary air filter assembly includes a motor arranged on the inner outer wall of the right end of the primary air filter channel, a controller is arranged above the motor, the motor is electrically connected to the controller, a rotating shaft is horizontally arranged at the left end of the motor, a secondary filter cartridge is horizontally arranged on the rotating shaft, a first spiral air guide channel is correspondingly arranged on the periphery of the secondary filter cartridge, a second spiral air guide channel is arranged on the periphery of the rotating shaft corresponding to the first spiral air guide channel, the left end of the secondary filter cartridge is connected to the left with a first air outlet pipe, a secondary filter bin is correspondingly arranged on the periphery of the first spiral air guide channel, and the controller can adopt a small controller PNOZmu lti 2 model controller, this controller can be applied to commonly used communication networks and can also connect, control and monitor multiple components at the same time.

The entire flow path is "straight line", and the gas filtering and exporting are carried out simultaneously, which effectively improves the efficiency of air intake filtering and exporting;The gas outlet assembly includes a second outlet pipe that is rotatably connected to the first outlet pipe through a rotating pipe joint.

[0015] 2. An oil bath layer is provided at the bottom of the secondary filter bin of the utility model. This arrangement can utilize the oil foam generated by the oil bath layer rotating with the secondary filter bin to allow the gas to be bathed in oil while being filtered by the secondary filter cartridge, thereby causing part of the dust and impurities contained in the gas to be adhered to the oil, which is conducive to achieving efficient filtration of the gas in a short time.

[0016] 3. The bottom of the air inlet channel of the utility model is located on the right side of the primary filter screen and is connected downwardly to a dust collecting pipe.

[0018] 5. The secondary filter cartridge of the utility model is formed by overlapping and sleeved multiple layers of filter screens, and the mesh size of the multiple layers of filter screens increases from the outside to the inside. This arrangement ensures the multi-level and high efficiency of gas filtration.

[0019] 6. The left end of the primary air filter channel of the utility model is arranged in the secondary filter bin and is located between the secondary filter bin and the secondary filter cylinder. The primary air filter channel as a whole presents a shape formed by a parabola opening to the left rotating circumferentially along the horizontal central axis, which is conducive to the normal transportation of the gas after the primary filtration and also avoids interference with the secondary filtration process of the gas.

[0020] 7. The right side wall of the secondary filter cartridge of the utility model is closed and fixedly connected to the right inner wall of the secondary filter bin. This arrangement ensures that the secondary filter cartridge and the secondary filter bin can rotate synchronously while also ensuring that the gas can only enter the cartridge through the cartridge wall of the secondary filter cartridge.

[0035] The specific operating principle is:

[0036] When using this air intake filter device, first connect the air intake filter device to an external power source, so that the flow sensor and the controller are in operation, and the motor and other electrical components are in standby state; then the gas to be introduced into the engine flows through the air intake pipe, is initially filtered by the primary filter screen, and then is introduced into the secondary filter bin through the primary filter channel. The controller controls the motor so that the motor starts and drives the shaft to rotate, which can synchronously drive the secondary filter cartridge, the first spiral air guide channel, the second spiral air guide channel and the secondary filter bin to rotate, so that the gas introduced into the secondary filter bin through the primary filter channel gradually passes through the wall of the secondary filter cartridge along with the guiding effect of the first spiral air guide channel. At the same time, the oil filter can be used to The oil foam generated by the bath layer rotating with the secondary filter bin causes the gas to be bathed in oil while being filtered by the secondary filter cartridge, so that some dust and impurities contained in the gas are adhered to the oil. The gas after being filtered by the secondary filter cartridge and bathed in the oil bath layer gradually flows through the left wall of the secondary filter cartridge along with the guiding effect of the second spiral air guide channel and enters the first air outlet pipe, and then is discharged from the shell through the second air outlet pipe. During the entire air intake filtration process, the flow rate of the intake air can be monitored in real time by the flow sensor, and the measured flow rate is then transmitted to the controller in real time in the form of an electrical signal. The controller controls the motor to switch to an appropriate speed according to the numerical value of the flow rate to ensure that the engine intake rate is always stable within a certain range.
