Description
Technical Field
The invention relates to an air inlet system of an engine, in particular to an integrated mixer.
Background
With the increasing severity of air pollution and the increasingly strict emission conditions, natural gas is widely used as a clean energy source in the industries of automobiles, power generation, engineering and the like. The market demand of natural gas is increased year by year, the requirement on combustion of the natural gas is higher and higher, and when the engine is used, the natural gas is required to be fully combusted when entering the engine, so that the mixing uniformity of the natural gas and air is of great importance. The mixer and the fuel gas injection system are two independent parts in the existing market, the injection system is connected through a long pipeline, enters the mixer for mixing and then enters an engine, and the long pipeline is connected to waste materials and have the defects of poor safety, time delay, unfavorable engine arrangement and the like.
Disclosure of Invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art by providing an integrated mixer.
The purpose of the invention can be realized by the following technical scheme:
an integrated mixer is connected with a gas inlet pipeline and comprises a mixer body, an injection component, a spoiler and a mixer core, wherein the spoiler and the mixer core are arranged in the mixer body, and the injection component is arranged on the mixer body;
air enters the mixer body, meanwhile, natural gas is directly sprayed into the mixer body through the spraying part, the natural gas and the natural gas are mixed through the mixer core, and then the mixed gas of the air and the fuel gas is obtained through the flow around of the spoiler.
Preferably, the mixer further comprises a pressing plate, and the injection part is pressed by the pressing plate.
Preferably, the pressure plate is connected with the mixer body through bolts.
Preferably, the spoiler is pressed into the mixer body by interference fit.
Preferably, said means for injecting comprises a nozzle which injects gas directly into the mixer body cavity.
Preferably, the mixer core is fixed by a spoiler.
Preferably, the mixer core is first loaded into the mixer body and then pressed into the spoiler.
Preferably, the mixer body is connected with the gas inlet pipeline by a flange.
Compared with the prior art, the invention has the following advantages:
firstly, the safety is high: the mixer and the injection component are connected without a pipeline joint, and the injection component is directly arranged on the mixer body, so that the danger of gas leakage can be avoided.
Secondly, the cost is low: and the two parts are made into one part, so that the cost is better controlled.
Thirdly, the mixing effect is good: the gas sprayed by the spraying component directly enters the mixer without entering other pipelines, so that the energy loss is reduced.

FIG. 2 is a schematic diagram of the right view structure of the present invention;
FIG. 3 is a left side view of the present invention;
fig. 4 is a schematic sectional view along the direction of C-C in fig. 1.
Wherein, the mixer comprises a mixer body 1, a mixer body 2, an injection component 3, a spoiler 4, a mixer core 5 and a pressure plate.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
As shown in fig. 1 to 4, an integrated mixer is connected to a gas intake pipe, the mixer includes a mixer body 1, an injection member 2, a spoiler 3 and a mixer core 4, the spoiler 3 and the mixer core 4 are installed in the mixer body 1, and the injection member 2 is installed on the mixer body 1;
air enters the mixer body 1, meanwhile, natural gas is directly sprayed into the mixer body 1 through the spraying part 2, the natural gas and the natural gas are mixed through the mixer core 4, and then the mixed gas of the air and the fuel gas is obtained through the circumfluence of the spoiler 3.
The mixer also comprises a pressure plate 5, and the injection part 2 is pressed by the pressure plate 5. The pressing plate 5 is connected with the mixer body 2 through bolts. The spoiler 3 is pressed into the mixer body 1 through interference fit.
Said injection means 2 comprise a nozzle which injects the gas directly into the chamber of the mixer body 1.
The mixer core 4 is fixed by a spoiler 3. The mixer core 4 is first inserted into the mixer body 1 and then pressed into the spoiler 3. The mixer body 1 is connected with a gas inlet pipeline by a flange.
The integrated mixer of the invention is a part assembly designed by the mixer and the injection component: the mixer body integrates a mixer core, an injection component and a spoiler together, and the mixer body is connected with a gas inlet pipeline by adopting a flange. The injection component is fixed on the mixer body through the pressure plate, and directly injects gas into the mixer cavity without passing through any pipeline, so that the circulation time of the pipeline after injection is shortened. The mixer core is arranged in the mixer body. The spoiler is pressed into the mixer body through interference fit.
The integrated mixer of the present invention works as follows: the air enters the mixer body, the natural gas is directly sprayed into the mixer through the spraying part, the air and the natural gas are mixed through the mixer core, and then the air and the natural gas are obtained through the flow around of the flow around plate.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
