Description

A car cartridge type air filter dust removal device with wading capability

technical field

The utility model relates to an automobile engine intake system, in particular to a dust discharge device for an automobile cylinder air filter with water wading capability.

Background technique

Under normal circumstances, when diesel engines are used in trucks or construction machinery, the working conditions are generally harsh and there is a lot of dust. Generally, a dust bag will be installed under the air filter assembly or at the bottom of the intake pipe to discharge the intake system. The dust in the air is mainly separated by the principle of centrifugal force. The dust falls into the bottom of the cartridge air filter shell under the action of gravity, and is discharged through the dust bag under the action of engine pulse intake and gravity. A small amount When water enters, it can also be discharged through the dust bag.

As shown in Figure 1, the structure of the existing dust removal device is as follows: the air filter 1 is connected with an air intake pipe 2 and an air exhaust pipe 3, and the bottom of the air filter 1 is provided with a dust discharge port 4 and a dust discharge port 4 The lower end is connected with a dust bag 5 having an opening. The air enters the air filter 1 through the air intake pipe 2, and the large particles of dust fall into the bottom of the air filter 1 through the centrifugal force generated by the internal swirl plate, and are discharged from the dust discharge bag 5 through the dust discharge port 4, and the clean air is discharged from the dust discharge bag 5 through the dust discharge port 4. The air exhaust pipe 3 is discharged.

However, the existing dust bag 5 is a middle opening structure formed by two-lobed rubber. When wading, the air filter assembly will be submerged in the water, and water will enter the filter from the dust bag, causing water to enter the engine. . If the dust discharge bag is canceled in order to meet the wading ability, the dust holding capacity of the air filter assembly will be seriously affected, and the dust cannot be discharged in time.

Therefore, there is a need to develop a car cylinder air filter dust removal device that has water-wading capability and can collect internal dust or water.

Contents of the invention

The purpose of this utility model is to solve the deficiency of the above-mentioned background technology, and provide a car cylinder air filter dust removal device which has the capability of fording water and can collect the internal dust or water.

The technical solution of the utility model is: a car cylinder air filter dust discharge device with wading ability, including an air filter with a dust discharge port, characterized in that the dust discharge port passes through a transparent rubber tube Connected to a closed dust collection tank connected to the chassis below the dust outlet.

Preferably, the dust collection tank includes an upper cover and a tank body which are movable and hermetically connected, and the upper cover is connected to the lower end of the transparent rubber tube.

Further, the upper cover and the tank body are screw-tightly connected.

Further, the upper cover is provided with a protruding connecting mouth, and the connecting mouth is fixedly connected to the lower end of the transparent rubber tube through a first clamp.

Preferably, the dust outlet is fixedly connected to the upper end of the transparent rubber hose through a second clamp.

Preferably, the dust collection tank is filled with oil.

The beneficial effects of the utility model are:

1. Dust is introduced into the closed dust collection tank through the transparent rubber tube. Even if the air filter assembly is submerged in water when driving ford, water will not enter the filter, ensuring the driving safety of the engine.

2. There is a proper amount of special oil in the dust collection tank, which is used to absorb dust and prevent dust from flying. According to the use of the whole vehicle, the amount of dust collected can be estimated, and the size of the dust collection tank can be designed to ensure that the vehicle is in the required condition. There is no need to clean the air filter dust frequently during the mileage.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in FIG. 1 , it is a structural schematic diagram of the dust-exhausting device of an automobile cartridge air filter in the prior art, which has been described in detail in the background art, and will not be repeated here.

As shown in Figure 2, the dust removal device for the automobile cylinder air filter with wading capability provided by the utility model includes an air filter 1 provided with a dust discharge port 4, and the air filter 1 is connected with an air inlet The air pipe 2, the air exhaust pipe 3, and the dust discharge port 4 are connected to the closed dust collection tank 7 through the transparent rubber tube 6, and the dust collection tank 7 is connected to the lower part of the dust discharge port 4 on the chassis (the dust collection tank 7 of this embodiment is located at bottom of chassis). The dust collection tank 7 is fixed on the chassis by a hoop type support.

The dust collecting tank 7 comprises a detachable upper cover 8 and a tank body 9 which are movable and hermetically connected, and the upper cover 8 and the tank body 9 are screw-tightly connected. The upper cover 8 is provided with a protruding connecting nozzle 10 , and the lower end of the transparent rubber tube 6 is sleeved on the connecting nozzle 10 and fixedly connected by a first clamp 11 . The upper end of the transparent rubber hose 6 is sleeved on the dust outlet 4 and fixedly connected by the second clamp 12 . Special oil liquid is housed in the dust collecting tank 7 .

The working principle of the utility model is:

When the engine is running, the air enters the air filter 1 through the air intake pipe 2, and rotates through the swirl plate in the air filter assembly. Under the action of centrifugal force, large particles of dust are separated and fall into the air filter. The bottom of the filter housing enters the transparent rubber tube through the dust discharge port at the lower part of the air filter assembly, and enters the dust collection tank 7 along the transparent rubber tube 6. The dust entering the dust collection tank 7 will be absorbed by the oil and form a solid form. .

When the dust filled the dust collecting tank 7, the dust would accumulate in the transparent rubber tube 6, and now the dust collection situation could be observed from the transparent rubber tube 6, if it was full, the dust would need to be cleaned up as required. Unscrew the detachable upper cover 8 of the dust collection tank 7 from the tank body 9, pour out the dust-oil mixture in the tank body 9, add oil after cleaning, and reinstall.

According to the usage of the vehicle, the amount of dust collected can be estimated, and the size of the dust collection tank 7 can be designed to ensure that the vehicle does not need to frequently clean the air filter dust within the required mileage. This can greatly increase the dust holding capacity of the air filter assembly, and it will not affect the normal use of the air filter when a small amount of water enters. At the same time, the whole vehicle has the ability to ford water. Check the collection of dust for timely treatment.
