Problems solved by technology

At present, paper dry filters are generally equipped with an air intake pipe and an air outlet pipe. The air intake pipe is directly connected to the outside to introduce external air into the paper dry filter. The air outlet pipe is directly connected to the cylinder of the internal combustion engine of the car. The filter does not pre-treat the air entering the intake system. After a period of use, a large amount of large particles of dust and impurities may accumulate on the filter element, resulting in low filtration efficiency and short service life of the filter.
[0003] On the other hand, the amount of air intake directly affects the running state of the automobile engine. With the increasing importance of energy saving and emission reduction, the technical space for reducing engine fuel consumption and improving engine performance with traditional technologies is very small, and the technical cost is high

Embodiment 1

[0028] What the present invention discloses is a kind of centrifugal filter pressurized air intake pipeline, such as Figure 1-8 As shown, it is a preferred embodiment of the present invention, such as figure 1 - As shown in 2, the intake duct includes a front section 1 and a rear section 2 that are independent of each other. One end of the front section 1 is the air inlet 11 of the entire intake duct, and the other end is sleeved outside one end of the rear section 2. The vane assembly 3 is installed to make the air flow rotate around the axis of the intake pipe. When the external air enters the intake pipe from the air inlet 11, the high-speed air flow begins to form an acceleration around the central axis of the intake pipe under the influence of the vane assembly 3 , and quickly form a peripheral velocity, and then the high-speed airflow spirals forward in the intake pipe. Impurities in the airflow also obtain circumferential speed. Due to their relatively large air mass,...

Embodiment 2

[0036] Further, in order to increase the intake air volume of the engine while pre-processing the air intake, the blade assembly can be driven by a motor, and the blade assembly driven by an external motor can increase the intake air volume while changing the direction of the airflow. Such as Figure 9 As shown, the design of the structure of the front section 1, the rear section 2, the annular dust outlet 12 and the dust collection tube 4 in this embodiment is the same as that of the first embodiment, the only difference is the blade assembly 3 installed in the front section 1. The blade assembly 3 may be a traditional fan blade, but due to the limited circumferential speed formed by the traditional fan blade, it may also be considered that the blade assembly 3 used is a spiral blade assembly. Similarly, the spiral leaf assembly includes a central shaft 33 and a spiral blade 31 whose inner edge is fixedly connected to the central shaft 33. There are spiral passages 32 between...

Abstract

The invention discloses a centrifugal filtration type supercharged air intake pipeline and a supercharged air intake filtration method. The air intake pipeline comprises a front section and a rear section. An air inlet is formed in one end of the front section, and the other end of the front section is connected to one end of the rear section in a sleeving manner. A blade assembly for making air flow rotate around the axis of the air intake pipeline is installed in the front section. An annular dust discharge opening is formed in the connection position of the front section and the rear section, and the outer side of the connection position is further wrapped by a dust collection barrel. The air intake pipeline and a paper dry type filter form a secondary filter system in cooperation. Whenintake air is filtered, large-particle dust impurities in the intake air are preprocessed first directly through the kinetic energy of the intake air, and therefore concentration of the impurities onthe paper dry type filter is greatly reduced, the service life of air-filter filter paper is prolonged, and the filtration efficiency of the filter is improved; and on the other hand, the blade assembly can be driven through an outside source motor, and therefore the air intake can be increased through the air intake pipeline while intake air preprocessing is achieved, and the operation performance of engines is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a centrifugal filter pressurized intake pipe and a pressurized intake filter method. Background technique [0002] The air filter is the core component of the automobile engine intake system. With the rapid development of the automobile industry, it has higher requirements for performance and service life. Automotive air filters generally include dry inertia air filters, wet inertia air filters, dry filter air filters and wet filter air filters, among which dry filter air filters Cleaner is the most widely used in automobile production because of its advantages of small weight, convenient production and installation. Dry filter air filters are commonly used in car engines, the most common of which is paper dry filters. The filter element of this type of filter is made of resin-treated microporous filter paper. The filter paper is porous, loose, It is easy to fold and has certain mecha...
