SUMMARY

[0005] In order to overcome the problem that the existing natural gas hydrogen mixing even mixing device does not have auxiliary stirring structure when using, only relies on the collision between natural gas and hydrogen and pipe wall and relative collision and mixes, and the density difference between natural gas and hydrogen is larger, and the problem of insufficient mixing easily occurs.

The driven gear drives the rotating shaft to rotate when rotating, thereby driving the stirring plate to rotate. The gas in the mixing tank is stirred to improve the mixing efficiency. The existing natural gas hydrogen mixing device does not have an auxiliary stirring structure, and only relies on the collision between natural gas and hydrogen and the relative collision with the pipe wall for mixing. However, the density difference between natural gas and hydrogen is large, which easily leads to insufficient mixing.

[0008] Preferably, the inner surface of the mixing tank is provided with a fixing ring below the stirring plate. The inner surface of the fixing ring is provided with one end of three circumferentially distributed support rods. The other end of the support rods is provided with a fixing disc. The upper surface of the fixing disc is rotatably connected with a rotating rod. The outer surface of the rotating rod is circumferentially provided with a plurality of blades.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a drive motor, its output end will drive the drive gear to rotate during operation. When the drive gear rotates, it can drive the driven gear meshing with it to rotate synchronously. When the driven gear rotates, it can drive the rotating shaft to rotate, thereby driving the stirring plate to rotate. This stirs the gas inside the mixing tank, thereby improving the mixing efficiency. This solves the problem that the existing natural gas-hydrogen blending uniform mixing device does not have an auxiliary stirring structure and relies solely on the collision and relative collision between natural gas and hydrogen and the pipe wall for mixing. However, the density difference between natural gas and hydrogen is large, which easily leads to insufficient mixing. Attached Figure Description
