Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid mixing equipment, in particular to a high-speed jet gas-liquid mixing reactor. Background Art

[0002] Gas-liquid mixing refers to injecting a special gas into a reactor containing liquid so that the gas can fully mix and react with the liquid. This reaction method is used in many chemical fields. The main purpose is to fully react the gas with the corresponding liquid to obtain the required derivatives.

[0003] Current gas-liquid mixing reactors all introduce gas into and out of liquid, and then stir and mix them. This method will cause the gas to remain in the liquid for a period of time, during which time the gas will float upwards and eventually separate from the liquid. The fusion efficiency is not high, so a gas-liquid mixing reactor is set up for this purpose. Utility Model Content

DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-4The utility model discloses a high-speed jet gas-liquid mixing reactor, comprising a reaction tank 1, a top plate 2 is fixedly connected to the top of the reaction tank 1, a stirring rod 5 is arranged inside the reaction tank 1, and the side walls on both sides of the stirring rod 5 are evenly fixedly connected with support arms 12, and the outer wall of the support arm 12 is evenly fixedly connected with an exhaust column 13, the stirring rod 5 and the support arm 12 are both hollow structures, the inside of the stirring rod 5 is communicated with the inside of the support arm 12, and the support arm 12 is communicated with the inside of the exhaust column 13, the bottom side wall of the reaction tank 1 is fixedly connected with a discharge pipe, and a valve is detachably connected to the discharge pipe;

[0015] The side walls on both sides of the exhaust column 13 are evenly fixedly connected with extension columns, the exhaust column 13 and the extension column are internally communicated with each other, and the opening at one end of the extension column away from the exhaust column 13 is rotatably connected to a sealing plate 14 through a torsion spring, a mounting groove 10 is opened inside the top plate 2 near one side, and a motor 11 is detachably connected to the mounting groove 10, a main gear 3 is set on the top of the top plate 2, the output end of the motor 11 passes through the top side wall of the mounting groove 10 and is detachably connected to the bottom side wall of the main gear 3, a slave gear 4 is meshedly connected to one side of the main gear 3, and a ring-shaped slider 16 is fixedly connected to the bottom side wall of the slave gear 4, a slide groove 15 is opened at the top of the top plate 2 opposite to the slider 16, and the slider 16 is rotatably connected in the slide groove 15.

[0016] The preferred technical effect of the present scheme is that the gas enters the stirring rod 5 through the gas injection pipe 6, is discharged into the corresponding support arm 12 through the stirring rod 5, is then injected into the corresponding exhaust column 13, and finally is injected into the liquid through an extension column on the side wall of the exhaust column 13. In order to prevent the liquid from entering the stirring rod 5 through the exhaust column 13, a sealing plate 14 is connected to the opening of the extension column via a torsion spring. The sealing plate 14 is closed under normal conditions and is only deployed to discharge gas under the drive of air pressure. When discharging gas, liquid is blocked from entering due to the air pressure. The injection of gas and the rotation of the stirring rod 5 are carried out synchronously, which can effectively improve the gas-liquid mixing efficiency and the reaction efficiency.

[0017] One end of the stirring rod 5 passes through the top plate 2 and is fixedly inserted and connected in the middle of the slave gear 4. A rotating groove is opened at one end of the stirring rod 5 located at the top of the slave gear 4. An air injection pipe 6 is set above the stirring rod 5. One end of the air injection pipe 6 is rotatably connected in the rotating groove. One end of the air injection pipe 6 is detachably connected to the air injection pump. A section of the outer wall of the air injection pipe 6 is fixedly connected with a fixing block 7. The fixing block 7 is detachably connected to the outer wall of one side of the reaction tank 1, and the outer wall of the reaction tank 1 near the bottom end is fixedly connected with an annular connecting ring 8, and the bottom side wall of the connecting ring 8 is fixedly connected with a support column 9.

[0018] The preferred technical effect of this scheme is that, in order to ensure the smooth rotation of the stirring rod 5, it is fixed in the middle of the slave gear 4. As the slave gear 4 rotates, the stirring rod 5 will also be driven to rotate synchronously. In order to ensure the smooth rotation of the slave gear 4, a slider 16 and a slide groove 15 are set to support the slave gear 4, ensuring that the slave gear 4 always remains in a horizontal state to avoid deflection and affect the stirring effect.

[0019] Specifically, when the utility model is used, the motor 11 located in the installation groove 10 is started in advance, and the main gear 3 is driven to rotate by the motor 11, and the slave gear 4 is driven to rotate synchronously through the meshing connection relationship, thereby driving the stirring rod 5 to rotate. As the stirring rod 5 rotates, it can drive the support arm 12 fixed thereto to rotate synchronously to achieve stirring of the liquid. At the same time, gas is injected into the stirring rod 5 through the gas injection pipe 6, and the gas enters the corresponding support arm 12 along the stirring rod 5, and then enters the corresponding exhaust column 13 through the flow of gas. The air pressure will push open the corresponding sealing plate 14 to inject the gas into the liquid. Because the liquid is in a state of rotating and stirring, the injected gas can also rotate synchronously with the liquid, thereby improving the efficiency of gas-liquid mixing and preventing the gas from escaping from the liquid. At the same time, the internal space of the stirring rod 5, the support arm 12 and the exhaust column 13 is gradually reduced. As the space is reduced, the flow rate and pressure will increase, thereby ensuring that the gas can be smoothly injected into the liquid, and the mixed product is finally discharged from the discharge pipe.

It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
