Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a liquid mixing tank. Background Technology

[0002] A mixing tank is a device used for mixing and stirring materials, widely used in food, dairy products, fruit juice beverages, pharmaceuticals, chemicals, and bioengineering. Its main functions include heating, cooling, heat preservation, and stirring to ensure uniform mixing of materials. Chinese utility model patent CN222841954U discloses a mixing tank device for producing chemical tin solution, comprising: a mounting frame, with support rods evenly mounted on the upper surface of the mounting frame, and a support frame mounted on the upper surface of the support rods; the support frame has a ring design; a mixing tank shell, located within the inner cavity of the support frame, with a discharge pipe installed at the bottom of the mixing tank shell; a motor, located on the upper surface of the mixing tank shell, with a main shaft coaxially extending through the upper surface of the mixing tank shell, and stirring rods evenly mounted on the surface of the main shaft; and a drive motor, located on the lower surface of the top plate of the mounting frame. A drive rod is coaxially mounted on the rotor, and a drive plate is screwed onto the surface of the drive rod. The drive plate is connected to the surface of the mixing tank shell. Scrapers are mounted on the surface of the stirring rod, and the scrapers are in contact with the inner wall of the mixing tank shell. The scrapers can remove the liquid adhering to the inner wall of the mixing tank. For liquids with low viscosity, only a small amount of pressure needs to be applied to the mixing tank by the scrapers to remove the liquid adhering to the inner wall of the mixing tank. This not only saves energy but also avoids damaging the mixing tank. For liquids with high viscosity, a large amount of pressure needs to be applied to the mixing tank by the scrapers to remove the liquid adhering to the inner wall of the mixing tank. However, the above-mentioned mixing tank device cannot adjust the pressure applied by the scrapers to the inner wall of the mixing tank, so it needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a liquid mixing tank to solve the technical problem that the existing mixing tank device cannot adjust the pressure applied by the scraper to the inner wall of the mixing tank.

[0004] To achieve the above technical objectives, the present invention provides a liquid mixing tank, comprising a tank body, an internal stirring shaft, a stirring rod mounted on the side wall of the stirring shaft, the stirring rod having an internal hollow structure, and a telescopic rod movably mounted inside, one end of the telescopic rod extending from the end of the stirring rod away from the stirring shaft and having a scraper mounted thereon, the stirring shaft having an internal hollow structure, and a connecting rod movably mounted inside, a conical block coaxially mounted on the connecting rod, the side wall of the conical block abutting against the other end of the telescopic rod, one end of the connecting rod abutting against an elastic element, the other end of the elastic element abutting against a threaded element, and the threaded element being threadedly connected to the upper end of the stirring rod.

[0005] Furthermore, the contact end between the telescopic rod and the conical block is provided with an inclined surface to ensure line contact between the conical block and the telescopic rod.

[0006] Furthermore, a sealing ring is provided on the inner wall of the end of the stirring rod away from the stirring shaft to seal the connection between the stirring shaft and the telescopic rod.

[0007] Furthermore, the inner wall of the upper end of the stirring shaft is provided with internal threads, and the threaded parts are connected to the inside of the upper end of the stirring shaft through the internal threads.

[0008] Furthermore, the stirring shaft is connected to a drive device for driving the stirring shaft to rotate.

[0009] Furthermore, the drive device includes a driven gear coaxially mounted on the stirring shaft, the driven gear meshing with the driving gear, and the driving gear connected to the output shaft of the drive motor.

[0010] Furthermore, the elastic element is a spring.

[0011] Furthermore, threaded parts are made using bolts.

[0012] The beneficial effects of this utility model include: This utility model provides a liquid mixing tank, in which the elastic element can be extended and retracted by adjusting the threaded part, thereby adjusting the pressure applied by the elastic element to the connecting rod. At the same time, the connecting rod can apply pressure to the telescopic rod through the conical block, thereby adjusting the pressure applied by the connecting rod to the telescopic rod, which in turn adjusts the pressure applied by the telescopic rod to the scraper. Therefore, the pressure applied by the scraper to the inner wall of the tank can be adjusted according to the viscosity of the liquid being mixed. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] This utility model embodiment provides a liquid mixing tank, such as Figure 1-2 As shown, the device includes a tank body 1, inside which is a stirring shaft 2. The upper end of the stirring shaft 2 is mounted on the top of the tank body 1 via a bearing. A stirring rod 3 is mounted on the side wall of the stirring shaft 2. The stirring rod 3 has a hollow internal structure and a telescopic rod 4 is movably mounted inside. Both ends of the stirring rod 3 are open. One end of the telescopic rod 4 extends from the end of the stirring rod 3 away from the stirring shaft 2 and is equipped with a scraper 5. The stirring shaft 2 has a hollow internal structure and a connecting rod 6 is movably mounted inside. The upper end of the stirring shaft 2 is open, and the lower end is closed. A conical block 7 is coaxially mounted on the connecting rod 6. The side wall of the conical block 7 abuts against the other end of the telescopic rod 4. One end of the connecting rod 6 abuts against an elastic element 8, which is one of a spring, a metal sheet, or a silicone block. The other end of the elastic element 8 abuts against a threaded element 9, which is one of a bolt or a screw. The threaded element 9 is threadedly connected to the upper end of the stirring rod 3.

[0020] By adjusting the threaded part 9, the elastic part 8 can be extended or retracted, thus adjusting the pressure applied by the elastic part 8 to the connecting rod 6. At the same time, the connecting rod 6 can apply pressure to the telescopic rod 4 through the conical block 7, thereby adjusting the pressure applied by the connecting rod 6 to the telescopic rod 4, which in turn adjusts the pressure applied by the telescopic rod 4 to the scraper 5. Therefore, the pressure applied by the scraper 5 to the inner wall of the tank 1 can be adjusted according to the viscosity of the liquid being stirred.

[0021] It should be noted that when the viscosity of the liquid is low, the scraper 5 only needs to apply a small pressure to the inner wall of the tank 1 to scrape the liquid from the inside of the tank 1. At this time, adjusting the threaded part 9 to extend the elastic part 8 reduces the pressure applied by the elastic part 8 to the connecting rod 6, thereby reducing the pressure applied by the scraper 5 to the inner wall of the tank 1. This not only saves energy but also avoids damaging the tank 1 and extends its service life. When the viscosity of the liquid is low, the scraper 5 needs to apply a larger pressure to the inner wall of the tank 1 to scrape the liquid from the inside of the tank 1. At this time, adjusting the threaded part 9 to shorten the elastic part 8 increases the pressure applied by the elastic part 8 to the connecting rod 6, thereby increasing the pressure applied by the scraper 5 to the inner wall of the tank 1 and scraping the liquid from the inner wall of the tank 1.

[0022] It should be noted that a feed hopper 11 is installed on the top of the tank body 1, through which liquid can be added into the tank body 1; a discharge port 12 is provided on the top of the tank body 1, through which the stirred liquid can be discharged from the inside of the tank body 1. At the same time, a discharge valve is installed on the discharge port 12 to control the liquid to be discharged through the discharge port 12.

[0023] In this embodiment, as Figure 3 As shown, the contact end between the telescopic rod 4 and the conical block 7 is provided with an inclined surface 41 so that there is line contact between the conical block 7 and the telescopic rod 4, thereby improving the reliability and stability of the contact between the telescopic rod 4 and the conical block 7.

[0024] To prevent liquid from inside tank 1 from entering the stirring rod 3 and stirring shaft 2, in this embodiment, as follows: Figure 4 As shown, a sealing ring 31 is provided on the inner wall of the end of the stirring rod 3 away from the stirring shaft 2. The sealing ring 31 is made of either a silicone ring or a rubber ring. The sealing ring 31 can seal the stirring shaft 2 and the telescopic rod 4 to prevent liquid from entering the stirring shaft 2 and the stirring rod 3.

[0025] It should be noted that the inner wall of the upper end of the stirring shaft 2 is provided with internal threads, and the threaded part 9 is connected to the inside of the upper end of the stirring shaft 2 through the internal threads.

[0026] In this embodiment, the stirring shaft 2 is connected to the driving device 10 for driving the stirring shaft 2 to rotate. The driving device 10 can drive the stirring shaft 2 to rotate, which in turn drives the stirring rod 3 to rotate. The stirring shaft 3 can drive the telescopic rod 4 to rotate, and the telescopic rod 4 can drive the scraper 5 to rotate. Therefore, the liquid inside the tank 1 can be stirred while the liquid inside the tank 1 is scraped off. In this embodiment, the driving device 10 includes a driven gear 101 coaxially mounted on the stirring shaft 2. The driven gear 101 meshes with the driving gear 102. The driving gear 102 is connected to the output shaft of the drive motor 103. The drive motor 103 is an electric motor, a hydraulic motor, or a pneumatic motor. The driving device 10 of this utility model is not limited to the above structure. For example, in some other embodiments, the driving device 10 includes a driven pulley coaxially mounted on the stirring shaft 2. The driven pulley meshes with the driving pulley via a belt. The driving pulley is connected to the output shaft of the drive motor 103. The drive motor 103 is an electric motor, a hydraulic motor, or a pneumatic motor.

[0027] Specific principle: Before stirring the liquid, the threaded part 9 is adjusted according to the viscosity of the liquid to be stirred. By adjusting the threaded part 9, the elastic part 8 can be extended or retracted, adjusting the pressure applied by the elastic part 8 to the connecting rod 6. At the same time, the connecting rod 6 can apply pressure to the telescopic rod 4 through the conical block 7, thereby adjusting the pressure applied by the connecting rod 6 to the telescopic rod 4, which in turn adjusts the pressure applied by the telescopic rod 4 to the scraper 5. Therefore, the pressure applied by the scraper 5 to the inner wall of the tank 1 can be adjusted. When stirring the liquid, the stirring shaft 2 can be driven to rotate by the driving device 10. The stirring shaft 2 can drive the stirring rod 3 to rotate, which in turn drives the telescopic rod 4 to rotate. The telescopic rod 4 can drive the scraper 5 to rotate, thus allowing the liquid inside the tank 1 to be stirred while the liquid inside the tank 1 is scraped off.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
