Technical Field
[0001] This utility model relates to the field of chemical reaction equipment technology, and in particular to a high-efficiency self-aspirating gas reaction stirring device. Background Technology
[0002] The high-efficiency self-priming gas reaction stirring device is a specialized piece of equipment used in chemical, pharmaceutical, and environmental protection fields to enhance mass transfer and reaction efficiency between gas and liquid. With a stirring shaft as its core, the device introduces external gas into the reaction system through a unique self-priming mechanism design. In chemical production, many reactions require thorough mixing of gas and liquid to promote the reaction, such as oxidation and hydrogenation reactions.
[0003] Currently, traditional gas reaction stirring devices typically introduce gas into the reactor via an external gas source, and then mix it using stirring blades. However, traditional stirring blades have limited dispersion effect on the gas, insufficient gas-liquid contact area, and slow reaction rate, which affects the mixing effect of gas and liquid. Therefore, an efficient self-priming gas reaction stirring device is proposed for improvement and upgrading. Utility Model Content

[0008] As a preferred embodiment of the above technical solution, the dispersing paddle is shaped as an inclined paddle, and the mixing paddle is shaped as an anchor paddle.
[0009] As a preferred embodiment of the above technical solution, the self-priming structure includes a self-priming sleeve, a suction pipe, and an injector. The self-priming sleeve is located in the upper middle part of the stirring shaft and communicates with the inside of the stirring shaft. The stirring shaft and the self-priming sleeve are rotatably mounted. A suction hole is provided on the outer side wall of the self-priming sleeve. One end of the suction pipe communicates with the suction hole, and the other end extends to the outside of the reaction vessel. A dust cap is rotatably mounted on one end of the suction pipe.
[0010] As a preferred embodiment of the above technical solution, a self-priming chamber is provided inside the stirring shaft, and the ejector is installed at the lower end of the stirring shaft and connected to the self-priming chamber, with the ejector outlet facing the bottom of the mixing tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Excellent gas-liquid mixing effect: By setting the upper dispersion paddle, the gas is dispersed into tiny bubbles, which increases the gas-liquid contact area. The lower mixing paddle promotes the liquid circulation flow, so that the bubbles are evenly distributed in the reactor, which promotes full gas-liquid mixing, improves the reaction rate and conversion rate, and is conducive to improving the gas and liquid mixing effect.
[0013] High-efficiency self-priming gas: The liquid forms a high-speed jet at the outlet of the ejector, which creates a negative pressure in the self-priming chamber. The liquid then flows into the chamber through the suction pipe and suction hole. The high-speed jet generated by the ejector creates a negative pressure in the self-priming chamber, enabling automatic gas intake. No external gas source is required, which simplifies the equipment structure, reduces costs, and provides high self-priming efficiency.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 5 As shown in the figure, this embodiment provides a high-efficiency self-aspirating gas reaction stirring device, including a reaction vessel 1. The reaction vessel 1 includes a feed pipe 4, a discharge pipe 6, and a support frame 2. The support frame 2 is located at the bottom of the outer wall of the reaction vessel 1, the discharge pipe 6 is located at the bottom of the reaction vessel 1, and a top bracket 3 is fixedly installed at the upper end of the reaction vessel 1. A stirring structure 7 is provided inside the reaction vessel 1. The stirring structure 7 includes a drive motor 71 fixedly installed inside the top bracket 3. The output shaft of the drive motor 71 is fixedly connected to a reducer 72. The output shaft of the reducer 72 is fixedly connected to a stirring shaft 73 through a coupling. Two dispersing paddles 76 are provided on the outer wall of the stirring shaft 73, and a mixing paddle 77 is provided below the dispersing paddles 76 on the stirring shaft 73. A self-aspirating structure 8 is provided on the outer side of the stirring shaft 73.
[0024] like Figures 3 to 4 As shown, a mixing tank 74 is fixedly installed inside the reactor 1. The dispersing paddle 76 and the mixing paddle 77 are both rotatably installed inside the mixing tank 74. The stirring shaft 73 is rotatably installed inside the reactor 1. A control panel 5 is fixedly installed on the outer wall of the reactor 1. An installation sleeve 75 is fixedly installed in the middle of each of the two dispersing paddles 76 and the installation sleeve 75 is fixedly installed on the outer wall of the stirring shaft 73. The mixing paddle 77 is fixedly sleeved on the outer wall of the stirring shaft 73. The dispersing paddle 76 is shaped as an inclined paddle, and the mixing paddle 77 is shaped as an anchor paddle.
[0025] By connecting the reducer 72 to the motor output shaft, the rotational speed is reduced and the torque is increased. A coupling is installed at the bottom of the reducer 72 to connect the output shaft of the reducer 72 to the stirring shaft 73 to achieve power transmission. Meanwhile, the upper dispersion paddle 76 is a multi-bladed oblique blade paddle used to disperse the self-absorbed gas into tiny bubbles and mix it with the liquid. The lower mixing paddle 77 is an anchor paddle used to push the liquid flow at the bottom of the reactor 1 to prevent material sedimentation.
[0026] like Figure 5 As shown, the self-priming structure 8 includes a self-priming sleeve 82, a suction pipe 81, and an injector 84. The self-priming sleeve 82 is located in the upper middle part of the stirring shaft 73 and communicates with the interior of the stirring shaft 73. The stirring shaft 73 and the self-priming sleeve 82 are rotatably mounted. A suction hole is provided on the outer side wall of the self-priming sleeve 82. One end of the suction pipe 81 is connected to the suction hole, and the other end extends to the outside of the reaction vessel 1. A dust cap is rotatably mounted on one end of the suction pipe 81. A self-priming chamber 83 is provided inside the stirring shaft 73. The injector 84 is installed at the lower end of the stirring shaft 73 and communicates with the interior of the self-priming chamber 83. The outlet of the injector 84 faces the bottom of the mixing tank 74.
[0027] By installing the ejector 84 at the lower end of the stirring shaft 73 and communicating with the inside of the stirring shaft 73, with the outlet of the ejector 84 facing the bottom of the mixing tank 74, when the stirring shaft 73 rotates, the liquid forms a high-speed jet at the outlet of the ejector 84, which generates a negative pressure in the self-priming chamber 83, thereby drawing in gas through the suction hole and the suction pipe 81.
[0028] The working principle and operation process of this utility model are as follows: First, the operator adds the reaction liquid into the reactor 1 through the feed pipe 4 and adjusts the liquid level control panel 5 to the appropriate position. At this time, the external power supply is turned on, and the drive motor 71 is started. The drive motor 71 drives the stirring shaft 73 to rotate through the reducer 72 and the coupling. The ejector 84 at the lower end of the stirring shaft 73 rotates with the stirring shaft 73. The liquid forms a high-speed jet at the outlet of the ejector 84, which creates a negative pressure in the self-priming chamber 83. External gas enters the self-priming chamber 83 through the suction pipe 81 and the suction hole, and then... The gas is ejected from the outlet of the injector 84 through the internal channel of the stirring shaft 73 and mixed with the reaction liquid. The two sets of dispersion paddles 76 on the upper layer of the stirring shaft 73 rotate to disperse the ejected gas into tiny bubbles. The mixing paddle 77 on the lower layer of the stirring shaft 73 drives the liquid to circulate, so that the bubbles are evenly distributed in the reaction vessel 1, achieving a thorough gas-liquid mixing reaction. According to the reaction requirements, the speed of the drive motor 71 can be adjusted through the control panel 5 to control the speed of the stirring shaft 73, thereby adjusting the gas intake and the gas-liquid mixing effect. After the reaction is completed, the drive motor 71 is turned off, and the reaction products are discharged through the discharge pipe 6.
