Abstract

The utility model discloses a gas rotational flow device used for an internal combustion engine or a diesel. The utility model is characterized in that the gas rotational flow device is composed of a set of turbine blades without a cut and a shell body which is used for fixing the blades, and the blades divide the shell body into contraction-shaped jet tubes of which the number is corresponding to the number of the blades. The shell body is a circular cylinder, the directions of the outlet and inflow of the blades are rotated into an angle, and the blades can be curved surfaces or flat surfaces.

Description

The gas cyclone device

The utility model relates to a kind of gas cyclone device that is used for internal-combustion engine or diesel engine, and the blade of a plurality of non-incisions of particularly a kind of usefulness is separated into annulus post housing in the gas cyclone device of a plurality of contraction shape jet pipes.

As everyone knows, enter the air abundance of combustion chambers of internal combustion engines, and air is abundant with mixing of fuel oil, can improves combustion characteristic to reach perfect combustion.Korean Patent C/V2105560U discloses a kind of internal-combustion engine of being used for, the air flow system that comprises an air-strainer and installation vortex device within it, it has a plurality of blades that have slit, improves mixing and engine performance of air and fuel.Yet this air flow system has destroyed jet pipe and has flowed because blade has slit, and it is bloated that air can not be splashed, and pressure can can't be converted into kinetic energy, causes tangential swirl velocity low, and the air quantity that enters reduces, and power is low, thereby fuel saving not.

The purpose of this utility model is to provide a kind of air inlet energy that can at utmost utilize pressure difference to produce, makes the tangential gas flow momentum of ejection big as far as possible, speed as quickly as possible, strengthen the gas cyclone device of rotating force.

To achieve these goals, the utility model adopts following technological scheme: a kind of gas cyclone device, it is characterized in that: it is made up of with the housing of fixing this blade the turbine blade of one group of non-incision, and blade is separated into the contraction shape jet pipe corresponding with the blade number to housing.

Compared with the prior art the utility model has conspicuous advantage:

1, it is bloated mobile to adopt subsonic effuser to splash, and can give full play of the energy of pressure difference, obtains to try one's best big airflow kinetic energy, jet speed and powerful whirlwind power.

2, outlet pressure is low, and the air inlet amount is big.

3, there is not slit on the blade, easily manufactured.

4, can prevent that fuel from sticking on the wall of gas handling system.

5, air fully mixes with fuel oil.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 7 is a utilization example of the present utility model.

To shown in Figure 6, the composition of the utility model gas cyclone device 9 is at annulus post housing 3 internal fixation four non-incision turbine blades 2 to be set as Fig. 1, and blade is separated into four to circle ring column and shrinks shape jet pipe 5.Blade adopts cold play to be fixed in the annulus post housing.Annulus post housing two ends are respectively equipped with hoop 4 and bind round 1 down.Blade Design becomes the outlet port direction and comes angle of flow path direction rotation, and as shown in Figure 2, Blade Design becomes three

curved surfaces

6,7,8.Blade of the present utility model also can be the plane, and the quantity of blade can be more.Interlobate distance is adjusted to the formation jet pipe and is flowed, and select the suitable air inlet sectional area and the ratio of discharge area, the acquisition big kinetic energy of trying one's best, flow path shrinks the jet pipe of shape concerning subsonic flow, pressure can be converted into kinetic energy, nozzle velocity is increased greatly, strengthened the rotating force in the admission line.Blade is made curved shape, and suction port place curvature is smaller, and air outlet place curvature can be greatly, makes direction blade that the air outlet locates and airintake direction at an angle, and purpose is in order to produce tangential gas flow.

Fig. 7 is use-case of the utility model.Gas cyclone device 9 is fixedly installed on the central authorities of air-strainer 10, in order to produce powerful air swirl.This device is fixed on the position between vaporizer 11 and the suction tude 12, is used for further increasing the active force of eddy current.This device is fixedly mounted on outlet pipe 13 ingress, improves exhaust to produce eddy flow.
