Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a self-stirring mixed gas / steam device without external power. Background Art

[0002] In engineering, many devices require gas / vapor at a specific temperature. One way to provide gas / vapor at a specific temperature is to mix cold and hot gas / vapor in proportion. However, this requires the mixing speed to be fast and the temperature to be uniform to meet the needs of the equipment.

[0003] If only relying on the impact and diffusion of cold and hot air / gas to mix, it is very slow, so some effective measures need to be taken to achieve fast and uniform mixing. The usually added mixing equipment, such as a mixer, requires a separate power source, which not only consumes a lot of energy, but also has very high equipment costs and operation and maintenance costs.

[0004] In summary, when the equipment requires gas / vapor at a specific temperature, the mixing of cold and hot gas / vapor by counteraction and diffusion is very slow. The use of stirring equipment requires a separate power source, consumes a lot of energy and has high equipment cost and operation and maintenance cost. Summary of the invention

[0005] The purpose of the patent of this invention: The invention is to solve the problem that when the equipment needs gas / vapor of a specific temperature, the mixing is very slow only by the impact and diffusion of cold and hot gas / vapor, and the use of stirring equipment requires a separate power source, consumes a lot of energy and has high equipment cost and operation and maintenance cost. The present invention provides a self-stirring mixed gas / vapor device without external power.

[0006] The object of the present invention is achieved as follows: a self-stirring mixed gas / steam device without external power comprises a gas flow channel, a front connecting shaft, a rear connecting shaft, a speed change device, two guide support frames, at least one large leaf blade group and at least one funnel blade group;

[0007] Two guide support frames are fixed in the gas flow channel in sequence along the inlet to the outlet direction of the gas flow channel. The front connecting shaft and the rear connecting shaft are respectively rotatably connected to a guide support frame. The front connecting shaft and the rear connecting shaft are connected through a speed change device. The large leaf blade group is fixed on the front connecting shaft, and the funnel blade group is fixed on the rear connecting shaft.

[0008] Furthermore, each guide support frame is equipped with a supporting rolling bearing, and the front connecting shaft and the rear connecting shaft are respectively connected to a guide support frame through at least one supporting rolling bearing.

[0009] Furthermore, a sealing cover is fixed above each guide support frame, which is sleeved on the front connecting shaft / rear connecting shaft and shields the supporting rolling bearing.

[0010] Furthermore, the blades of the funnel blade group include a plurality of funnel-shaped modules connected to each other, the openings of the funnel-shaped modules are arranged horizontally, and the closing ends of the funnel-shaped modules are provided with a plurality of small holes.

[0011] Furthermore, the plurality of small holes on the funnel-shaped module are evenly distributed.

[0012] Beneficial effects:

[0013] This patent uses the flow of mixed gas / steam as a power source to achieve the automatic stirring and mixing function of cold and hot gas / steam, which can save a lot of costs and quickly and evenly mix the gas / steam.

[0014] The gas / steam flow entering the gas flow channel will have a certain initial velocity, and does not require other external power sources. It can first flush one or more groups of large leaf blade groups to make the large leaf blade groups rotate; the large leaf blade group is fixed on the front connecting shaft to drive the front connecting shaft to rotate; the front connecting shaft and the rear connecting shaft are connected through a speed change device, which can increase the rotation angular velocity of the rear connecting shaft; the funnel blade group is fixed on the rear connecting shaft, and the high-speed rotating rear connecting shaft drives the funnel blade group to rotate at a high speed, and the blades of the funnel blade group contain multiple groups of funnel-shaped structures, which can carry and delay the release of gas / steam, that is, gas / steam of different temperatures can be carried to other areas, thereby enhancing the stirring and mixing effect, and can quickly stir and mix cold and hot gas / steam.
