Description

Technical Field

[0001] This utility model relates to the field of gypsum powder processing technology, specifically a dissolving tank for processing high-strength gypsum powder. Background Technology

[0002] A dissolving tank for high-strength gypsum powder processing is a device specifically designed to mix gypsum powder with water to prepare gypsum slurry. To ensure long-term use and prevent chemical corrosion, the dissolving tank is typically made of corrosion-resistant materials, such as stainless steel or steel with a special coating. During processing, an internal stirring device within the dissolving tank thoroughly mixes the water and gypsum powder to obtain the desired gypsum slurry. Additionally, the dissolving tank can be optionally equipped with a heating element to heat the water, thereby accelerating the dissolution rate of the gypsum powder and improving the quality of the solution by appropriately increasing the temperature.

[0003] Patent CN217139974U discloses a dissolving tank for processing high-strength gypsum powder. It includes a rotating shaft rotatably connected to the upper end of an outlet pipe, a stirring rod on the side of the rotating shaft, a connecting groove at the upper end of the rotating shaft, a transmission head rotatably connected to the center of the lower end of a placement tank, connecting grooves and connecting plates on the upper and lower ends of the transmission head, a mounting plate slidably connected inside the placement tank, a motor on the upper end of the mounting plate, a rotating shaft below the mounting plate, a stirring rod on the rotating shaft, a connecting plate at the lower end of the rotating shaft, a connecting plate on the left side of the upper end of the placement tank, support rods 1 and 2 on the left and right sides of the upper end of the dissolving tank, support plates 1 and 2 on the upper ends of support rods 1 and 2, and cylinders 1 and 2 on opposite ends of support plates 1 and 2, respectively. This method results in rapid gypsum powder dissolution and minimizes the formation of solid precipitates in the prepared gypsum solution.

[0004] However, the dissolving tank in the above-mentioned technology still has the following problems: During the preparation of gypsum slurry using the dissolving tank, gypsum slurry with a specific viscosity is sometimes prepared as needed. However, after the dissolving and stirring steps are completed, this more viscous gypsum slurry often adheres to the stirring device and is difficult to remove easily, increasing the overall workload and cleaning difficulty of gypsum slurry preparation. Utility Model Content

A drive port is provided through the annular groove on the side near the lifting plate, and a drive assembly is provided in the drive port.

[0009] Furthermore, the drive assembly includes a drive motor and a drive gear. The drive motor is mounted on the side of the lifting plate near the drive port via a motor mount. The output shaft of the drive motor is fixedly connected to the drive gear. The outer wall of the rotating ring is provided with several tooth grooves. The drive gear passes through the drive port and meshes with the tooth grooves.

[0010] Furthermore, the scraping assembly includes a lifting plate, two lifting cylinders, and two symmetrically arranged U-shaped lifting frames. The lifting plate is located directly above the bucket lid. The tops of the three stirring rods pass through three perforations and are connected to the lifting plate. The two lifting cylinders are fixedly connected to both ends of the top of the bucket lid. The outer shells of the two lifting cylinders extend upward through the lifting plate and are slidably connected to the lifting plate. The telescopic ends of the two lifting cylinders extend upward and are fixedly connected to the inner walls of the two U-shaped lifting frames.

[0011] Furthermore, continuous spiral blades are fixedly connected to the outer walls of the three stirring rods, and annular positioning grooves are opened on the inner walls of the three perforations.

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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 7 A high-strength gypsum powder processing dissolving tank includes a mixing tank 2 mounted on a base 1. A tank cover 3 is connected to the top of the mixing tank 2. Three through holes 301 are provided through the upper surface of the tank cover 3. A stirring rod 4 is provided in each of the three through holes 301. The tops of the three stirring rods 4 pass through the three through holes 301 and are connected to a scraping component. A rotating component is connected to the outside of the tank cover 3. A lifting plate 5 is connected to the outside of the rotating component. The other end of the lifting plate 5 is connected to a lifting component. The lifting component is connected to the base 1.

[0025] like Figures 1 to 7 As shown, the main improvement of this utility model lies in reducing the cleaning process of the stirring rod 4 and improving the processing efficiency of gypsum powder, such as... Figures 1 to 7 As shown, in use, the high-strength gypsum powder processing dissolving tank of this utility model uses a lifting component to cover the mixing tank 2 with a lid 3. Then, a rotating component drives the lid 3 and the stirring rods 4 to rotate, thereby mixing the gypsum powder and the mixed liquid in the mixing tank 2. After the gypsum powder dissolves into the mixed liquid, a scraping component moves the three stirring rods 4 upward on the lid 3. With the help of the perforation 301, the gypsum slurry adhering to the surface of the stirring rods 4 is scraped off to the bottom of the lid 3. After the bottom of the stirring rods 4 is flush with the bottom of the lid 3, the lifting component lifts the lid 3 upward, thereby exposing the gypsum slurry in the mixing tank 2. At this point, only the gypsum slurry adhering to the bottom of the lid 3 needs to be cleaned, reducing the cleaning process of the stirring rods 4 and improving the efficiency of gypsum slurry dissolving and mixing.

[0026] like Figures 1 to 5As shown, the lifting assembly includes a U-shaped lifting frame 6, a threaded rod 7, and a lifting motor 8. Both ends of the U-shaped lifting frame 6 penetrate downwards through the lifting plate 5 and are fixedly connected to the base 1. The lifting motor 8 is fixedly connected to the top center of the U-shaped lifting frame 6. The output shaft of the lifting motor 8 penetrates the top of the U-shaped lifting frame 6 and is fixedly connected to the threaded rod 7. The other end of the threaded rod 7 penetrates through the lifting plate 5 and is rotatably connected to the base 1. The threaded rod 7 is threadedly connected to the lifting plate 5. When the mixing tank 2 is opened, the lifting motor 8 is started, driving the threaded rod 7 to rotate, thereby causing the lifting plate 5 to gradually move upwards, thus opening the mixing tank 2. The U-shaped lifting frame 6 supports the lifting plate 5, and both ends of the U-shaped lifting frame 6 also limit the vertical movement of the lifting plate 5, improving the stability of the lifting plate 5 during its vertical movement.

[0027] like Figures 1 to 7 As shown, the rotating assembly includes a circular frame 9 and a rotating ring 10. The inner wall of the rotating ring 10 is fixedly connected to the outer wall of the bucket lid 3. The circular frame 9 is fixedly connected to the lifting plate 5. An annular groove 901 is provided on the inner wall of the circular frame 9. The rotating ring 10 is rotatably connected to the annular groove 901. A drive port 902 is provided through the annular groove 901 near the lifting plate 5. A drive assembly is provided in the drive port 902. When the stirring rods 4 need to stir and mix the gypsum powder and the mixed liquid inside the mixing bucket 2, the drive assembly drives the rotating ring 10 to rotate in the annular groove 901 of the circular frame 9. This causes the bucket lid 3 to rotate horizontally at the top of the mixing bucket 2, which in turn causes the three stirring rods 4 to rotate inside the mixing bucket 2, thereby stirring and mixing the gypsum powder and the mixed liquid inside the mixing bucket 2 to finally obtain gypsum slurry.

[0028] like Figures 1 to 7 As shown, the drive assembly includes a drive motor 11 and a drive gear 12. The drive motor 11 is mounted on the side of the lifting plate 5 near the drive port 902 via a motor mount. The output shaft of the drive motor 11 is fixedly connected to the drive gear 12. The outer wall of the rotating ring 10 has several toothed grooves 101. The drive gear 12 passes through the drive port 902 and meshes with the toothed grooves 101. When the drive motor 11 is started, it drives the drive gear 12 to rotate. Then, through the meshing of the toothed grooves 101 with the drive gear 12, the rotating ring 10 and the bucket cover 3 rotate inside the ring frame 9 to mix the gypsum powder.

[0029] like Figures 1 to 7As shown, the scraping assembly includes a lifting plate 13, two lifting cylinders 14, and two symmetrically arranged U-shaped lifting frames 15. The lifting plate 13 is located directly above the bucket lid 3. The tops of the three stirring rods 4 pass through three through holes 301 and are connected to the lifting plate 13. The two lifting cylinders 14 are fixedly connected to the two ends of the top of the bucket lid 3, respectively. The outer shells of the two lifting cylinders 14 extend upward through the lifting plate 13 and are slidably connected to the lifting plate 13. The telescopic ends of the two lifting cylinders 14 extend upward and are fixedly connected to the inner walls of the two U-shaped lifting frames 15, respectively. After the gypsum powder is mixed, the two lifting cylinders 14 drive the two U-shaped lifting frames 15 to move upward, which in turn drives the lifting plate 13 to gradually move away from the bucket cover 3. This simultaneously lifts the three stirring rods 4 upward. At this time, the gypsum paste attached to the outer wall of the three stirring rods 4 will be scraped off by the perforation 301 during the lifting process and left at the bottom of the bucket cover 3. This scrapes off the gypsum paste attached to the outside of the three stirring rods 4 and leaves it at the bottom of the bucket cover 3 or drops it into the mixing bucket 2, reducing the cleaning process of the stirring rods 4.

[0030] like Figures 1 to 7 As shown, continuous spiral blades 16 are fixedly connected to the outer walls of the three stirring rods 4. Annular positioning grooves 302 are provided on the inner walls of the three through holes 301. Positioning rings 17 are rotatably connected to the three annular positioning grooves 302. Annular scrapers 18 are fixedly connected to the inner walls of the three positioning rings 17. Spiral grooves 102 matching the continuous spiral blades 16 are provided on the inner walls of the three annular scrapers 18. The continuous spiral blades 16 are slidably connected to the spiral grooves 102. The three stirring rods 4 are slidably connected to the inner walls of the three annular scrapers 18 respectively. A linkage mechanism is connected to the top of the lifting plate 13, and the linkage mechanism is connected to the top of the three stirring rods 4. When using the stirring rod 4 to stir and mix the gypsum powder and the mixture in the mixing tank 2, the three stirring rods 4 are driven to rotate inside the mixing tank 2 synchronously through the linkage mechanism. The rotating stirring rod 4 can stir and mix the gypsum powder and the mixture in the mixing tank 2 through the continuous spiral blades 16 on the outside. With the overall rotation of the tank cover 3, the stirring and dissolving effect of the gypsum powder in the mixing tank 2 is further improved, and the viscous gypsum slurry is prevented from not being fully stirred and mixed. When the stirring rod 4 rises to scrape off the attached gypsum slurry, the continuous spiral blades 16 drive the annular scraper 18 to rotate in the perforation 301 through the spiral groove 102. This allows the stirring rod 4 with the continuous spiral blades 16 to rise smoothly, and the gypsum slurry attached to the surface of the stirring rod 4 and the continuous spiral blades 16 is scraped off by the annular scraper 18 below the tank cover 3. The connection between the positioning ring 17 and the annular positioning groove 302 can ensure that the annular scraper 18 is always in the perforation 301.

[0031] like Figures 1 to 7As shown, the linkage mechanism includes a linkage motor 19, a driving gear 20, and two driven gears 21. The tops of the three stirring rods 4 are all fixedly connected to the driving gear 20 and the two driven gears 21 respectively after passing through the lifting plate 13 via a rotating shaft. The two driven gears 21 are located on both sides of the driving gear 20, and both driven gears 21 mesh with the driving gear 20. A lifting plate 22 is fixedly connected to one side of the two adjacent U-shaped lifting frames 15. The linkage motor 19 is fixedly connected to the bottom of the lifting plate 22, and the output shaft of the linkage motor 19 is fixedly connected to the driving gear 20. By starting the linkage motor 19, the driving gear 20 is driven to rotate, which simultaneously drives the two driven gears 21 on both sides to rotate, thereby causing the three stirring rods 4 at the bottom of the bucket lid 3 to rotate simultaneously. It should be noted that the tops of the stirring rods 4 are connected and fixed to the corresponding driving gear 20 or driven gear 21 through the lifting plate 13 via a rotating shaft. The rotating shaft is fixed to the lifting plate 13 by bearings, thereby ensuring that the stirring rods 4 and the lifting plate 13 remain in a fixed position during the lifting and scraping process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
