[0002] Stirred tanks, especially, are widely used as mixing and reaction vessels in the pharmaceutical, chemical, and food industries. In a broad sense, a stirred tank is a vessel that undergoes physical or chemical reactions. Through structural design and parameter configuration, the performance principle of the vessel is the same as that of a reaction vessel, realizing the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. The configuration, design conditions, process, inspection, manufacturing, and acceptance of stirred tanks must be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-to-high-speed mixing reaction functions required by the process.

[0003] In the process of industrial product manufacturing, in order to achieve homogeneous mixing between different raw materials and facilitate subsequent processing and quality control of industrial products, it is necessary to use a mixing vessel to mix the raw materials. However, most existing mixing vessels are used for unidirectional mixing, resulting in poor mixing effect. Furthermore, during mixing, uneven mixing and stratification of the raw materials inside the mixing vessel can easily occur, affecting the mixing effect of the raw materials. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a mixing and homogenizing stirring vessel that has the advantages of mixing and homogenizing, and solves the problem that most existing stirring vessels only mix in one direction and have poor mixing effect during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and homogenizing stirring vessel, comprising a stirring vessel, an inner liner inside the stirring vessel, a stirring rod inside the inner liner, the top of the stirring rod penetrating to the top of the stirring vessel and fixedly connected to a first motor, the bottom of the first motor being fixedly connected to the top of the stirring vessel, a hollow tube fixedly connected to the top surface of the inner liner, a branch pipe connected to the bottom of the hollow tube, the inner side of the branch pipe being fixedly connected to the surface of the inner liner, the output end of the branch pipe penetrating to the interior of the inner liner, a ring slidably connected to the top of the interior of the hollow tube, a connector connected to the top of the ring, the input end of the connector penetrating to the front of the stirring vessel and connected to an air pump, the back of the air pump being fixedly connected to the front of the stirring vessel, a second motor fixedly connected to the left side of the stirring vessel, a gear fixedly connected to the output end of the second motor, and the right side of the gear penetrating to the interior of the stirring vessel.

The side of the protective shell near the mixing vessel is fixedly connected to the surface of the mixing vessel, and the surface of the protective shell is provided with air holes.

[0008] As a preferred embodiment of this utility model, the top of the connector is connected to a one-way control valve, and the input end of the one-way control valve is connected to a water inlet pipe.

[0009] As a preferred embodiment of this invention, a limiting frame is fitted at the bottom of the surface of the stirring rod, and the bottom of the limiting frame is fixedly connected to the inner wall of the inner liner.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, the mixing and homogenizing stirring vessel provided by this utility model includes a stirring vessel 1, which is a common stainless steel stirring vessel on the market. The stirring vessel 1 has an inner liner 2 inside, and a stirring rod 3 inside the inner liner 2. The top of the stirring rod 3 extends through to the top of the stirring vessel 1 and is fixedly connected to a first motor 4. The bottom of the first motor 4 is fixedly connected to the top of the stirring vessel 1. A hollow tube 5 is fixedly connected to the top of the surface of the inner liner 2. A branch pipe 6 is connected to the bottom of the hollow tube 5. The inner side of the branch pipe 6 is fixedly connected to the surface of the inner liner 2. The output end of the branch pipe 6 extends through to the interior of the inner liner 2. A ring 7 is slidably connected to the top of the interior of the hollow tube 5. A connector 8 is connected to the top of the ring 7. The input end of the connector 8 extends through to the front of the stirring vessel 1 and is connected to an air pump 9. The back of the air pump 9 is fixedly connected to the front of the stirring vessel 1. A second motor 10 is fixedly connected to the left side of the stirring vessel 1. A gear 11 is fixedly connected to the output end of the second motor 10. The right side of the gear 11 extends through to the interior of the stirring vessel 1.

[0023] refer to Figure 3 The inner liner 2 has a toothed groove 12 on its surface that is used to cooperate with the gear 11. The right side of the gear 11 meshes with the surface of the inner liner 2. The left side of the stirring vessel 1 has a through hole 13 that is used to cooperate with the gear 11.

[0024] As a technical optimization of this utility model, the tooth groove 12 can facilitate the rotation of the gear 11 to drive the inner liner 2, hollow tube 5 and branch tube 6 to rotate counterclockwise. The through hole 13 can reduce the friction between the gear 11 and the stirring vessel 1.

[0025] refer to Figure 6 The air pump 9 is provided with a filter block 14. The filter block 14 and the second motor 10 are both provided with a protective shell 15. The protective shell 15 is fixedly connected to the surface of the mixing vessel 1 on the side close to the mixing vessel 1. The protective shell 15 is provided with air holes 16 on its surface.

[0026] As a technical optimization of this utility model, the filter block 14 can filter the air entering the air pump 9, preventing dust and debris in the air from entering the air pump 9. The protective shell 15 can limit and protect the positions of the second motor 10 and the air pump 9. The air hole 16 can facilitate the air pump 9 to take in air and facilitate the second motor 10 to dissipate heat.

[0027] refer to Figure 6 The top of connector 8 is connected to a one-way control valve 17, and the input end of the one-way control valve 17 is connected to a water inlet pipe 18.

[0028] As a technical optimization of this utility model, the one-way control valve 17 can prevent the air pump 9 from delivering air into the water inlet pipe 18, and at the same time prevent water from being delivered into the hollow pipe 5 and the branch pipe 6 when water is not needed. The water inlet pipe 18 can be conveniently delivered into the hollow pipe 5 and the branch pipe 6 to clean the debris attached to the inside of the branch pipe 6.

[0029] refer to Figure 3 A limiting frame 19 is fitted on the bottom of the surface of the stirring rod 3, and the bottom of the limiting frame 19 is fixedly connected to the inner wall of the inner liner 2.

[0030] As a technical optimization of this utility model, the position of the stirring rod 3 can be limited by the setting of the limiting frame 19, so as to prevent the stirring rod 3 from shaking when rotating clockwise.

[0031] refer to Figure 3 The top of the inner liner 2 is slidably connected to a retaining ring 20. A bolt is provided inside the retaining ring 20, and the threaded end of the bolt extends to the outside of the retaining ring 20 and is threadedly connected to the inner wall of the mixing vessel 1.

[0032] As a technical optimization of this utility model, the position of the inner liner 2 can be limited by the setting of the retaining ring 20 to prevent the inner liner 2 from falling off the mixing vessel 1. The position of the retaining ring 20 can be fixed by the setting of the bolt to prevent the retaining ring 20 from falling off the mixing vessel 1.

[0033] The working principle and usage process of this utility model are as follows: During use, the user pours the raw materials into the inner liner 2 inside the mixing vessel 1 through the feed end. Then, the first motor 4 is started. The output end of the first motor 4 drives the stirring rod 3 to rotate clockwise, causing the stirring rod 3 to stir and mix the raw materials inside the inner liner 2. Simultaneously, the second motor 10 and the air pump 9 are started. The output end of the second motor 10 drives the gear 11 to rotate clockwise. The clockwise rotation of the gear 11 causes the inner liner 2, hollow tube 5, and branch pipe 6 to rotate counterclockwise. At the same time, the air pump 9 draws air from the outside of the protective shell 15, and the air passes through the filter block 1. At 4 o'clock, the air is filtered, and then the output end of the air pump 9 delivers the filtered air to the inside of the branch pipe 6 through the connector 8 and the hollow pipe 5. Then, the raw materials inside the inner tank 2 are sprayed through the branch pipe 6, so that the raw materials at the bottom of the inner tank 2 are mixed and contacted with the raw materials at the top through the air. At this time, the raw materials inside the mixing vessel 1 are mixed and homogenized. When cleaning, the user opens the one-way control valve 17, and then the user delivers water through the water inlet pipe 18, the one-way control valve 17 and the connector 8 to the inside of the hollow pipe 5 and the branch pipe 6 to clean the raw materials remaining inside the branch pipe 6.

[0034] In summary, this mixing and homogenizing reactor, through the coordinated use of the mixing vessel 1, inner liner 2, stirring rod 3, first motor 4, hollow tube 5, branch pipe 6, ring 7, connector 8, air pump 9, second motor 10, and gear 11, solves the problems of existing mixing vessels, which mostly involve unidirectional mixing, resulting in poor mixing effect and easy heterogeneous stratification of raw materials inside the mixing vessel, thus affecting the mixing effect of the raw materials.
