[0021] The mixing chamber 1 in the utility model is connected with a cooling chamber 10, the cooling chamber 10 is sleeved on the outer rotor 5, and a movable gap is provided between the cooling chamber 10 and the outer rotor 5 for the outer rotor 5 to move, and the cooling chamber 10 is connected with a cooling water inlet 11 and a cooling water outlet 12. Rapid cooling can be achieved and the durability of operation can be improved.

[0022] The width of the reaction gap 7 in the present invention is 7.5 mm to 10 mm. The width of the reaction gap 7 in the present invention is preferably 7.5 mm.

[0023] The working principle of the utility model is as follows:

[0024] During specific operation, a reaction gap is provided between the inner rotor and the outer rotor to form a transition flow, wherein the inner rotor is used to allow the raw material to form an inner circle of liquid film, and the outer rotor is used to allow another raw material to form an outer circle of liquid film. By controlling the rotation speed of the inner and outer rotors, the inner and outer circle liquid films can form corresponding low shear forces for mixing between the liquids, which are then discharged through the raw material outlet after mixing.

[0025] During the above operation, the gap between the inner rotor and the outer rotor is adjustable (7.5mm-10mm), and the rotation speed is adjustable, that is, the speeds of the two fluids are adjustable, which are adjusted by their respective drive motors. The motors are existing equipment known to those skilled in the art and will not be described in detail.

[0026] In the above operation process, the Reynolds number is an important parameter for judging the fluid motion state. When it is less than 2000, it indicates laminar flow, when it is greater than 4000, it indicates turbulent flow, and between 2000 and 4000, there is a transition state.

[0027] Reynolds number calculation Re=ρvd / μ, where v, ρ, μ are the velocity, density and viscosity coefficient of the fluid respectively, and d is a characteristic length. That is, if the fluid flows through a circular pipe, d is the equivalent diameter of the pipe. The Reynolds number can be used to distinguish whether the flow of the fluid is laminar or turbulent, and can also be used to determine the resistance encountered by an object flowing in a fluid.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of this application, it should be noted that the terms "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
