[0002] A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. From the initial feeding-reaction-discharging, the pre-set reaction steps can be completed with a high degree of automation, and important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), and reactant / product concentrations during the reaction process are strictly regulated.

[0003] However, since the raw materials inside the reactor need to be stirred during use, the disturbance range of the stirring paddle is limited, which results in a longer stirring and mixing time. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The inner stirring frame inside the outer stirring frame will be thrown outward under the action of centrifugal force, thereby reducing the overall distance between the outer stirring frame, the inner stirring frame and the inner wall of the reactor. At the same time, the embedded through holes opened on the inner stirring frame can allow the liquid to flow freely, so that the flow speed difference of the internal liquid can be achieved during the stirring process, forming a certain vortex and accelerating the stirring and mixing efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides a high-efficiency and energy-saving chemical reactor, including a reactor 1, a drive motor 3 is installed at the upper end of the reactor 1, and the lower end of the drive motor 3 passes through the interior of the reactor 1 and is connected to a drive shaft 9, an outer array of the drive shaft 9 is installed, the outer array of the drive shaft 9 is fixedly connected to the drive shaft 9, an inner array of the outer array of the outer array 902 is provided, the inner array of the outer array 901 is provided with a movable through hole located on the outer side of the inner array 902, a spring 903 is connected in array between the inner array 902 and the outer array 901, an anti-slip pad 904 is installed at one end of the inner array 902 close to the spring 903, the anti-slip pad 904 is fixedly connected to the outer array 901 through the spring 903, and an embedded through hole 905 is provided inside the inner array 902.

[0024] like Figure 2-3 As shown, in this embodiment, a partition 2 is installed on the outer side of the lower end of the reactor 1, and a hanger 8 is installed on the outer array of the partition 2. A heat storage mechanism 10 is provided between the partition 2 and the reactor 1. The heat storage mechanism 10 includes: an outer coil 1001, an inner coil 1002, and a pump body 1003. The outer coil 1001 and the inner coil 1002 are arranged through. A manhole 7 is installed on the upper end of the reactor 1. A feed hole 4 is installed on one side of the manhole 7 located at the upper end of the reactor 1. A cleaning pipe 6 is installed on the other side of the manhole 7 located at the upper end of the reactor 1. The feed hole 4 and the cleaning pipe 6 are both arranged through the reactor 1. A pressure pipe 5 is installed on one side of the drive motor 3 located at the upper end of the reactor 1.

[0025] The working principle of the present invention is as follows: when in use, after the raw materials that need to be mixed and reacted are filled into the interior of the reactor 1 from the position of the feed hole 4, the reactor 1 is started to drive the driving motor 3 to drive the driving shaft 9 to rotate as a whole, and the rotating driving shaft 9 will drive the outer stirring frame 901 to rotate. The rotating outer stirring frame 901 will be subjected to a large centrifugal force as a whole, so the inner stirring frame 902 inside the outer stirring frame 901 will be thrown outward under the action of the centrifugal force, so the spring 903 will be stretched, and the anti-slip pad 904 at the end of the inner stirring frame 902 can prevent the inner stirring frame 902 from being thrown out from the inside of the outer stirring frame 901. When the driving shaft 9 is controlled to rotate at different speeds, the inner stirring frame 902 The frame 902 will be subjected to centrifugal forces of different sizes, and the extended length can be controlled to adjust the stirring efficiency. Therefore, the overall distance between the outer stirring frame 901, the inner stirring frame 902 and the inner wall of the reactor 1 can be reduced. At the same time, the embedded through hole 905 opened on the inner stirring frame 902 can provide free flow of liquid, so that the flow velocity difference of the internal liquid can be achieved during the stirring process, forming a certain vortex, thereby increasing the mixing efficiency of the internal liquid. The outer coil 1001 is installed inside the partition 2, and the inner coil 1002 is installed inside the reactor 1. The outer coil 1001 and the inner coil 1002 are placed in a heat-insulating or cooling liquid through the pump body 1003 to cope with different stages of liquid processing.
