Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

The specific implementation manner of the utility model is as follows: as shown in fig. 1-4, a large-scale gas engine mixer comprises a hollow mixer main body 1, an air inlet 2 arranged at one end of the mixer main body 1, a mixed gas outlet 5 arranged at one end of the mixer main body 1, and a gas inlet 3 arranged at one side of the mixer main body 1, wherein a mixer core 4 is arranged in an inner cavity of the mixer main body 1, and a turbulent flow grating 6 is arranged at one end of the inner cavity of the mixer main body 1, which is close to the mixed gas outlet 5. In this large-scale gas engine blender, air and gas get into in the blender main part 1, carry out the intensive mixing through blender core 4, then flow direction gas mixture export 5, and flow down at the disturbance of vortex grid 6, make air and gas intensive mixing once more, can make gas redirecting during the grid, thereby strengthen the mixture, make the mixture of gas and air more even, be favorable to the burning of combustible gas mixture, improve combustion efficiency, reduce the detonation and the risk of catching fire, can promote the reliability of engine, mechanical efficiency and reduce and discharge.

In this embodiment, air intlet 2,

gas mixture export

5 and 3 departments of gas import are equipped with flange, the business turn over gas piping connection of being convenient for, and simple to operate is quick.

In this embodiment, the inner cavity of the mixer main body 1 is provided with an annular gas cavity 7 adapted to the gas inlet 3, the inner cavity of the mixer main body 1 is a through hole penetrating through both ends of the inner cavity, and the annular gas cavity 7 is an annular groove structure recessed radially outward on the hole wall of the through hole. Annular gas chamber 7 surrounds blender core 4 setting on the chamber wall of blender main part 1, and the gas flows into annular gas chamber 7 from gas import 3, can make the gas fully contact with the lateral wall of blender core 4 to in getting into blender core 4, guarantee that the gas flows unobstructed and the gas can be abundant with air mixing.

In this embodiment, the mixer core 4 is a cross-shaped hollow structure, a first vent hole extending axially is formed in the mixer core 4, a second vent hole communicated with the first vent hole and arranged radially is formed in the side wall of the mixer core 4, and air enters the inner cavity of the mixer core 4 from the peripheral side of the mixer core 4 and is mixed with air.

In this embodiment, one end of the cavity wall of the mixer main body 1 is provided with a positioning step, the inner cavity of the mixer main body 1 is provided with a positioning cylinder 8, two ends of the positioning cylinder 8 are respectively matched with the positioning step and one end of the mixer core 4, the inner cavity of the mixer main body 1 is inserted with a pressing cylinder 9 which is matched with the other end of the mixer core 4, and the positioning cylinder 8 and the pressing cylinder 9 can be inserted into the inner cavity of the mixer main body 1 from the mixed gas outlet 5. The mixer core 4 is positioned through the positioning cylinder 8 and the pressing cylinder 9, so that the mixer core 4 can be quickly installed in the mixer main body 1, the mixer core 4 is ensured to be installed in place, the mixer core 4 is arranged corresponding to the annular gas cavity 7, and the accuracy of the installation position is ensured; moreover, the positioning cylinder 8 is of a cylindrical structure, so that materials are convenient to obtain, the manufacturing is simple, and the maintenance and the replacement are convenient.
