Description

Technical Field

[0001] The present invention belongs to the technical field of electrically assisted turbochargers, and more specifically, particularly relates to an electrically assisted turbocharger with a double filtering system. Background Art

[0002] An E-Boosting Turbocharger is an improved turbocharger that incorporates the assistance of an electric motor to provide additional boost when the efficiency of the turbocharger is insufficient, especially at low speeds or when the engine load varies greatly. Traditional turbochargers often have a "worm gear lag" problem at low speeds. This is because the exhaust volume is not enough to drive the turbocharger to run at high speed, resulting in unsatisfactory boost effect at low engine speeds. The E-Boosting Turbocharger is designed to solve this problem by providing additional power to drive the compressor through an electric motor when the turbocharger is not fully engaged, thereby achieving a faster boost response.

[0003] The existing electrically assisted turbocharger usually relies on a filter element to filter the air during operation, which has the following technical problems: Since the air often contains a lot of dust, particles and other impurities, especially in a dusty environment, a lot of dust and impurities will gradually accumulate on the surface of the filter element after long-term use. These impurities will block the pores of the filter element, causing the permeability of the filter element to deteriorate. When the permeability of the filter element decreases, the intake flow rate will be restricted, resulting in the compressor being unable to obtain enough air, thereby reducing the boost efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an electrically assisted turbocharger with a dual filtering system to solve the above problems.

[0005] An electrically assisted turbocharger with a dual filtering system comprises a compressor, wherein the compressor is provided with a compressor inlet and a compressor outlet, the compressor is also provided with a conical cylinder, the side wall of the top of the conical cylinder is provided with an air inlet, the air inlet is tangent to the conical cylinder, the top center of the conical cylinder is rotatably connected with a connecting cylinder, the center of the interior of the conical cylinder is provided with a rotating cylinder with air seepage holes, the outer peripheral side wall of the rotating cylinder is provided with rotating cylinder blades, the top of the rotating cylinder is fixedly connected to the bottom of the connecting cylinder, the top of the connecting cylinder is rotatably connected to the air filter inlet end of the air filter, the air filter outlet end is connected to the compressor inlet, and the compressor is also provided with a dual-shaft motor, one output shaft of the dual-shaft motor is connected to the compressor blades of the compressor, and the other output shaft of the dual-shaft motor drives the connecting cylinder and the rotating cylinder to rotate through a transmission device.

[0006] Preferably, the conical cylinder includes two parts connected in an upper and lower manner, the upper part is a cylindrical air cylinder, and the lower part is a conical cylinder body, the air inlet is arranged on the side wall of the air cylinder, the connecting cylinder is rotatably connected to the air inlet end of the air filter with a sealed bearing, the transmission device includes a worm and a worm wheel, the worm wheel is sleeved on the top of the connecting cylinder, and the worm is fixedly connected to the output shaft of the dual-axis motor.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a double filtering device is provided, that is, a group of filtering devices is added in front of the air filter to improve the filtering effect of dust and other pollution in the air, thereby avoiding clogging of the air filter and affecting the air intake.

[0010] In the present invention, a rotating cylinder is arranged in the conical cylinder so that the rotating cylinder drives the high-speed rotation of the rotating cylinder blades. On the one hand, the gas in the conical cylinder produces a strong rotational motion to form a rotating airflow to promote gas dust removal; on the other hand, the flow speed of the gas is accelerated, thereby increasing the intake flow rate of the compressor.

[0011] In the present invention, the compressor blades and the rotating cylinder are connected by the output shafts on both sides of the dual-shaft motor, so that the rotation speed of the compressor blades is linearly positively correlated with the rotation speed of the rotating cylinder, thereby realizing automatic matching of the air intake volume and the gas dust removal efficiency. When the rotation speed of the compressor blades increases, the rotation speed of the rotating cylinder also increases synchronously, and the air intake volume and the dust removal rate increase synchronously; when the rotation speed of the compressor blades decreases, the rotation speed of the rotating cylinder also decreases synchronously, and the air intake volume and the dust removal rate decrease synchronously.

A dual-shaft motor 6 is also provided on the compressor 9, one output shaft of the dual-shaft motor 6 is connected to the compressor blades of the compressor 9, and the other output shaft of the dual-shaft motor 6 drives the connecting cylinder 16 and the rotating cylinder 14 to rotate through the transmission device 3.

[0016] The conical cylinder 2 includes two parts connected in an upper and lower manner, the upper part is a cylindrical wind cylinder 19, and the lower part is a conical cylinder body. The air inlet 1 is arranged on the side wall of the wind cylinder 19, and the connecting cylinder 16 is rotatably connected to the air inlet end of the air filter inlet end 4 with a sealed bearing. The transmission device 3 includes a worm 17 and a worm wheel 18. The worm wheel 18 is sleeved on the top of the connecting cylinder 16, and the worm 17 is fixedly connected to the output shaft of the dual-axis motor 6. The rotating cylinder 14 includes a rotating cylinder upper edge 15, and the rotating cylinder upper edge 15 is fixedly connected to the connecting cylinder 16.

A control device is arranged on the compressor 9, and the control device is used to control the dual-axis motor 6.

[0017] Working principle: The rotation of the compressor blades draws the dust-containing or liquid droplet-containing gas into the interior of the conical cylinder 2 through the air inlet 1 at a certain speed. In the conical cylinder 2, the airflow is constrained by the inner wall of the conical cylinder 2 and guided by the rotating cylinder blades, generating a strong rotational motion to form a rotating airflow. The dust particles or liquid droplets in the rotating airflow are thrown to the outer wall of the conical cylinder 2 under the action of inertial centrifugal force. Once these particles come into contact with the inner wall of the conical cylinder 2, they lose their inertial force and fall along the inner wall under the action of gravity to the drain pipe 5 for discharge. The rotating airflow gradually shrinks in the cylinder body and flows toward the center to form a secondary vortex, which enters the air filter 10 through the rotating cylinder 14 and the connecting cylinder 16 for secondary filtration, and then the air after the secondary filtration enters the compressor.

[0018] By arranging the rotating cylinder 14 in the conical cylinder 2, the rotating cylinder 14 drives the rotating cylinder blades 13 to rotate at a high speed. On the one hand, the gas in the conical cylinder 2 produces a strong rotational motion to form a rotating airflow to promote gas dust removal. On the other hand, it also speeds up the flow speed of the gas and increases the intake flow rate of the compressor.
