[0002] Emulsification mixing tanks are mainly used for the preparation and premixing of various liquids, such as pharmaceuticals, daily chemicals, food, adhesives, and chemical products. They have a wide range of applications. The inventor is aware of an emulsification mixing tank that has an internal stirring device. The stirring device includes a rotating shaft and stirring blades fixed on the rotating shaft. A motor is located on the top of the tank. One end of the rotating shaft is connected to the output shaft of the motor, and the other end of the rotating shaft is suspended. When the rotating shaft rotates and when stirring materials, the rotating shaft will shake. The shaking of the rotating shaft is particularly obvious when stirring more viscous materials, which affects the stirring effect of the materials.

[0003] Therefore, how to design an emulsification mixing tank to improve the stability of the rotating shaft and enhance the mixing effect on materials is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to address the defects and deficiencies in the existing technology by providing an emulsification mixing tank, which improves the stability of the rotating shaft and enhances the mixing effect on the materials by supporting both ends of the rotating shaft.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an emulsification mixing tank, including a tank body, a stirring device, a support component, and a drive assembly for driving the stirring device to rotate. The stirring device includes a rotating shaft that is pulverizedly connected to the drive assembly and stirring blades placed inside the tank body and fixed on the rotating shaft. The support component is placed inside the tank body, and the top surface of the support component is connected to the end of the rotating shaft away from the drive assembly to support the rotating shaft.

[0007] Preferably, the axis of the rotating shaft coincides with the central axis of the tank, the support component has a cavity inside, and the side and bottom surfaces of the support component are provided with openings that communicate with the cavity, and the opening on the bottom surface communicates with the material outlet of the tank.

[0008] Preferably, the bottom of the tank is also provided with an emulsifying shearing device, the stator of the emulsifying shearing device and the rotor placed in the stator both extend into the interior of the tank, and the top surface of the stator is provided with a mixing material inlet, and the side surface of the stator is provided with a mixing material outlet.

[0009] Preferably, two or more of the emulsifying shearing devices are provided at intervals along the circumference of the tank.

[0010] Preferably, the stirring blade is a frame-type stirring blade.

[0011] Preferably, the end face of the frame-type stirring blade away from the rotating shaft is also provided with a scraper, which is in contact with the inner wall of the tank to scrape off the material adhering to the inner wall of the tank.

[0012] Preferably, the bottom end of the frame-type stirring blade is higher than the inlet of the mixture; the scraper includes a first scraper disposed on a portion of the frame-type stirring blade and a second scraper disposed on the remaining frame-type stirring blade, the first scraper covering the area from the middle part of the liquid surface to the highest liquid surface, and the second scraper covering the area from the middle part of the liquid surface to the bottom of the tank.

[0013] Preferably, the tank body is also provided with a heating device that surrounds the side wall of the tank body.

[0014] Preferably, the heating device is a heating jacket, the interior of which is provided with a cavity for filling a heating medium, and the heating jacket is provided with a heating medium inlet and a heating medium outlet respectively connected to the cavity.

[0015] Preferably, the top of the tank is also provided with a feeding port for adding the material to be processed and an observation mirror for observing the material processing in the tank.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] 1. This utility model provides a support component inside the tank. One end of the rotating shaft of the stirring device is connected to the drive assembly located on the top of the tank, and the other end of the rotating shaft is connected to the top surface of the support component. The drive assembly and the support component support both ends of the rotating shaft respectively, thereby improving the stability of the rotating shaft and thus improving the stirring effect.

[0018] The other technical solutions of this utility model have achieved the following technical effects compared with the prior art:

[0019] 2. Because the mixture will settle at the bottom of the tank, this application places the emulsification and shearing device at the bottom of the tank to improve the emulsification and shearing effect. However, in the prior art, the stirring blades extend to the bottom of the tank, which causes the material at the bottom of the tank to be constantly agitated during operation, reducing the amount of material entering the mixture inlet and thus weakening the emulsification and shearing effect of the emulsification and shearing device on the material in the tank. To address this, this application sets the bottom of the frame-type stirring blades higher than the mixture inlet, and the scraper includes a first scraper and a second scraper. The first scraper only covers the upper middle area of ​​the inner wall of the tank, and the second scraper only covers the lower middle area of ​​the inner wall of the tank. This allows the material at the bottom of the tank to be agitated only intermittently, reserving sufficient time for the mixture to be drawn into the mixture inlet, thereby increasing the amount of mixture entering the mixture inlet and improving the emulsification and shearing effect on the material in the tank. In addition, two or more emulsification and shearing devices are arranged at intervals along the circumference of the tank, which can increase the coverage area of ​​the material at the bottom of the tank, thereby further improving the emulsification and shearing effect on the material in the tank.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, this utility model provides an emulsification mixing tank, including a tank body 2, a stirring device, a support component 7, and a drive assembly for driving the stirring device to rotate. The drive assembly is located on the top of the tank body 2. The stirring device includes a rotating shaft 14 driven by the drive assembly and stirring blades located inside the tank body 2 and fixed to the rotating shaft 14. The support component 7 is located inside the tank body 2, and the end of the rotating shaft 14 away from the drive assembly is connected to the top surface of the support component 7 to support the rotating shaft 14. Compared with the prior art where only one end of the rotating shaft 14 is driven by the drive assembly and the other end is suspended, this application can improve the stability of the rotating shaft 14, thereby improving the stirring effect. The drive assembly includes a motor 16 and a reducer 17 driven by the motor 16, and the rotating shaft 14 is driven by the reducer 17. When the support component 7 is fixed inside the tank body 2, the rotating shaft 14 is rotatably connected to the support component 7; when the support component 7 is rotatably connected to the tank body 2, the rotating shaft 14 is fixedly connected to the support component 7. In an exemplary embodiment, the support member 7 is fixed inside the tank 2, and the rotating shaft 14 is rotatably connected to the top surface of the support member 7.

[0026] When the rotating shaft 14 is tilted, the supporting component 7 will not obstruct the material outlet of the tank 2. Therefore, the supporting component 7 can be a solid structure or a structure with an internal cavity and openings on the side. When the rotating shaft 14 is vertically installed inside the tank 2 (i.e., the axis of the rotating shaft 14 coincides with the central axis of the tank 2, which improves the stability during stirring), the supporting component 7 is positioned to coincide with the material outlet of the tank 2. In this case, to ensure that the material in the tank 2 can be discharged smoothly, the supporting component 7 is designed to have an internal cavity and openings on the side and bottom. The opening at the bottom is connected to the material outlet of the tank 2, allowing the emulsified and uniformly stirred material to flow into the material outlet through the opening on the supporting component 7, thereby discharging the material. The bottom surface of the supporting component 7 refers to the surface that is in contact with the inner wall of the tank 2, the top surface refers to the surface located at the top of the supporting component 7 and in contact with the rotating shaft 14, and the remaining surfaces of the supporting component 7 are all side surfaces.

[0027] Because the emulsification effect of a simple stirring device is limited, this application also includes an emulsifying shearing device 10 at the bottom of the tank 2. The emulsifying shearing device 10 is inclined at the bottom of the tank, with the inclination direction facing the center of the tank 2. The stator and rotor of the emulsifying shearing device 10 both extend into the interior of the tank 2. The top surface of the stator has a mixing material inlet 11, and the side surface of the stator has a mixing material outlet (not shown in the figure). The material enters the area between the stator and rotor through the mixing material inlet 11. Under the high-speed rotation of the rotor, large particles are sheared into smaller particles, and the sheared material is thrown out from the mixing material outlet into the interior of the tank 2, thereby enhancing the emulsification and shearing effect on the material inside the tank 2. Here, the stator and rotor refer to the structure within the emulsifier, not the structure within the motor. Furthermore, the mixing material inlet 11 is positioned higher than the material outlet of the tank 2.

[0028] To reduce the resistance exerted on the mixing blades by viscous materials during the mixing process and improve the mixing effect, this application sets the mixing blades as frame-type mixing blades 13. Frame-type mixing blades 13 refer to mixing blades that only have a frame structure, with the interior of the frame structure being hollow and without any filler. A scraper is provided on the end face of the frame-type mixing blade 13 away from the rotation axis 14. The scraper is in contact with the inner wall of the tank 2 to scrape off the material adhering to the inner wall of the tank 2.

[0029] If all the scrapers directly cover the entire liquid level in the tank 2, the material at the bottom of the tank 2 will be constantly stirred, which is not conducive to the material entering the mixing inlet 11 of the shear emulsification device, thus weakening the emulsification effect of the material. To solve this technical problem, this application sets the scrapers to include a first scraper 4 set on a portion of the frame-type stirring blades 13 and a second scraper 12 set on the remaining frame-type stirring blades 13. The first scraper 4 covers the area from the middle part of the liquid surface to the highest liquid surface, and the second scraper 12 covers the area from the middle part of the liquid surface to the bottom of the tank 2. To illustrate the arrangement of the first scraper 4 and the second scraper 12, consider a cross-section passing through the central axis of the tank 2. If the first scraper 4 is installed on the frame-type stirring blades 13 located on the left side of the cross-section passing through the central axis, and the second scraper 12 is installed on the frame-type stirring blades 13 located on the right side of the cross-section passing through the central axis, then all frame-type stirring blades 13 located on the left side of the cross-section passing through the central axis will have the first scraper 4 installed, and all frame-type stirring blades 13 located on the right side of the cross-section passing through the central axis will have the second scraper 12 installed. There will be no situation where some frame-type stirring blades 13 located on the left side of the cross-section passing through the central axis have the first scraper 4 installed, and other frame-type stirring blades 13 located on the left side of the cross-section passing through the central axis have the second scraper 12 installed. The arrangement of the scrapers on the frame-type stirring blades 13 located on the right side of the cross-section passing through the central axis is similar. This design allows sufficient time for the mixture at the bottom of tank 2 to fully enter the emulsifying shearing device 10, thereby improving the emulsification effect on the material inside tank 2. To ensure proper operation of the device, the movement trajectories of the frame-type stirring device 13 and the second scraper 12 are designed not to intersect with the emulsifying shearing device 10. Furthermore, to prevent material on the side furthest from the emulsifying shearing device 10 from settling at the bottom of tank 2, two or more emulsifying shearing devices 10 are spaced apart along the circumference of tank 2.

[0030] The tank body 2 is also equipped with a heating device that surrounds the side wall of the tank body 2. The heating device can be an electric heating tube, heating coil, or other components. In an exemplary embodiment, the heating device is a heating jacket 6 (i.e., a sandwich structure disposed on the outer wall of the tank body 2). The heating jacket 6 has a cavity inside for filling with a heating medium. The heating jacket 6 has a heating medium inlet 3 and a heating medium outlet 5, which are respectively connected to the cavity. A cover is provided at the heating medium outlet 5. When heating medium is filled into the heating jacket 6, the cover is closed. When it is necessary to discharge the heating medium from the heating jacket 6, the cover is opened. The heating medium can be hot water, steam, heat transfer oil, etc. In an exemplary embodiment, the heating medium is heat transfer oil.

[0031] The top of the tank 2 is also equipped with a feeding port 1 for adding materials to be processed and an observation mirror 15 for observing the material processing inside the tank 2. A discharge pipe 8 is also connected to the material outlet of the tank 2, and a valve 9 is installed on the discharge pipe 8. When it is necessary to discharge the stirred and emulsified material, the valve 9 is opened; otherwise, the valve 9 is closed.

[0032] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
