Non-powered fluid mixing device

technical field

The invention relates to a mixing device, in particular to a non-powered fluid mixing device.

Background technique

The current mixing devices all use motors to drive the stirring blades to stir and mix in a closed container. This mixing method not only occupies a large area, but also requires a motor as power for stirring, and it takes a long time to mix evenly and has low efficiency.

Contents of the invention

The purpose of the present invention is to overcome the above disadvantages and provide a non-powered fluid mixing device, which is provided with more than two stirring devices and the helical angles of the helical stirring blades in each stirring device are different, which can be directly connected to the pipeline Using the flow of fluid to drive each stirring device to achieve stirring at different speeds, it not only occupies a small area, does not require additional power, but also stirs evenly and has high efficiency.

The present invention is achieved in the following way: a non-powered fluid mixing device, including a body, a mixing cavity is arranged in the body, and the feature is that the device also includes more than two stirring devices arranged in the mixing cavity, so The body also includes inlet 1 and inlet 2 arranged at one end of the mixing chamber, and an outlet arranged at the other end of the mixing chamber. Each stirring device includes a stirring shaft sleeve rotatably connected to the mixing chamber, The helical stirring blades and more than one stirring rod fixed on the stirring shaft sleeve, the helical angle of each helical stirring blade is different.

In order to achieve stirring in different directions and make the stirring more uniform, the spiral directions of two adjacent spiral stirring blades are different.

Preferably, the axis of the stirring rod is perpendicular to the stirring shaft sleeve and uniformly distributed around the axis of the stirring shaft sleeve.

Preferably, the body further includes a fixed shaft coaxially fixed in the mixing chamber, and the stirring sleeves of each stirring device are coaxially sleeved on the fixed shaft.

Compared with the prior art, the present invention has the following advantages:

(1) The unpowered fluid mixing device provided by the present invention is provided with more than two stirring devices and the helical angles of the spiral stirring blades in each stirring device are different, and can be directly connected to the pipeline and utilize the flow of the fluid to drive each stirring device The device realizes stirring at different speeds, which not only occupies a small area, does not require additional power, but also stirs evenly and has high efficiency;

(2) In the unpowered fluid mixing device provided by the present invention, the helical directions of two adjacent helical stirring blades are different, which can realize stirring in different directions, making the stirring more uniform;

(3) The non-powered fluid mixing device provided by the present invention has the advantages of simple structure, energy saving and environmental protection, uniform stirring, reliable performance, and easy popularization and application.

detailed description

The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments of the description:

As shown in Figures 1 to 3, a non-powered fluid mixing device provided by the present invention includes a body 1, and a mixing chamber 11 is provided in the body 1, and the feature is that the device also includes more than two The stirring device 2 arranged in the mixing chamber 11, the body 1 also includes an inlet one 12 and an inlet two 13 arranged at one end of the mixing chamber 11, an outlet 14 arranged at the other end of the mixing chamber 11, each stirring device 2 includes a stirring shaft sleeve 21 rotatably connected to the mixing chamber 11, a spiral stirring blade 22 fixed on the stirring shaft sleeve 21, and more than one stirring rod 23 fixed on the stirring shaft sleeve 21, each spiral stirring blade 22 have different helix angles.

In order to achieve stirring in different directions and make the stirring more uniform, the spiral directions of two adjacent spiral stirring blades 22 are different.

Preferably, the axis of the stirring rod 23 is perpendicular to the stirring sleeve 21 and uniformly distributed around the axis of the stirring sleeve 21 .

Preferably, the body 1 further includes a fixed shaft 15 coaxially fixed in the mixing chamber 11 , and the stirring sleeves 21 of each stirring device 2 are coaxially sleeved on the fixed shaft 15 .

The unpowered fluid mixing device provided by the present invention is connected to the fluid pipeline during use, and then the fluid to be mixed with it is inserted from the inlet two 13 (flocculant in this embodiment), because each stirring device The helical angles of the helical stirring blades 22 on the 2 are all different, and the helical directions of two adjacent helical stirring blades 22 are different. The flow of the fluid can drive each stirring device 2 to rotate in different directions and at different speeds, which not only occupies a small area, but also No extra power is needed, and the stirring is even and efficient.

The above-mentioned specific implementation is only a detailed explanation of the technical solution of the present invention, and the present invention is not limited to the above-mentioned embodiments, and any improvement or replacement based on the principle of the present invention shall fall within the scope of protection of the present invention.
