Technical Field
[0001] This utility model relates to the field of calcium carbonate processing and modification technology, specifically to an auxiliary device for surface modification of ultrafine heavy calcium carbonate. Background Technology
[0002] Ultrafine heavy calcium carbonate refers to a functional inorganic material with an average particle size between 0.02 and 0.1 μm. It exhibits diverse crystal morphologies, including calcite, aragonite, and spherulite, and possesses high specific surface area and active surfaces, thus demonstrating excellent reinforcing, toughening, and functional modification effects in composite materials. To improve dispersibility, enhance compatibility, reduce oil absorption, and other properties to meet market demands, surface modification of ultrafine heavy calcium carbonate is necessary.
[0003] In existing technologies, when surface-modifying ultrafine heavy calcium carbonate, modifiers are generally added to the ultrafine heavy calcium carbonate raw material, and the mixture is stirred to achieve the modification operation. However, in the use of existing mixing tanks, ultrafine heavy calcium carbonate accumulates at the bottom of the tank. When it comes into contact with the modifier, ultrafine heavy calcium carbonate is prone to accumulating and agglomerating at the bottom of the mixing tank, which seriously affects the modification effect of ultrafine heavy calcium carbonate and is not conducive to practical applications.
[0004] Therefore, those skilled in the art provide an auxiliary device for surface modification of ultrafine heavy calcium carbonate to solve the problems mentioned in the background art. Utility Model Content

[0008] The above technical solution involves installing a dispersion cylinder with dispersion holes inside the modification tank, and installing spiral blades inside the dispersion cylinder to lift the ultrafine heavy calcium carbonate at the bottom of the modification tank. The spiral blades continuously lift the ultrafine heavy calcium carbonate at the bottom of the modification tank into the dispersion cylinder, where it is dispersed and discharged through the dispersion holes.

[0013] Preferably, the modified tank has an annular heating groove inside, and electric heating tubes are installed at equal intervals on the top of the sealing cover, with all electric heating tubes extending into the interior of the heating groove.
[0014] The above technical solution utilizes an electric heating tube to uniformly heat ultrafine heavy calcium carbonate material, thereby drying the ultrafine heavy calcium carbonate powder and preventing it from caking during the modification process.

Simultaneously, an inlet pipe for introducing a modifier is located outside the dispersion cylinder, ensuring better mixing of the discharged ultrafine heavy calcium carbonate with the introduced modifier. This guarantees the modification effect of the device on the ultrafine heavy calcium carbonate and facilitates practical application and operation. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] Reference Figures 1-5 This utility model provides an auxiliary device for surface modification of ultrafine heavy calcium carbonate, including a modification tank 1 and a sealing cap 2. The sealing cap 2 is threaded to the top of the modification tank 1 for easy opening. The modification tank 1 has an annular heating groove 15 inside. Electric heating tubes 16 are equidistantly installed on the top of the sealing cap 2, extending into the heating groove 15. The electric heating tubes 16 uniformly heat the ultrafine heavy calcium carbonate material, drying the powder and preventing clumping during modification. A feeding funnel 17 is installed on the top of the sealing cap 2, extending to the bottom of the sealing cap 2, allowing ultrafine heavy calcium carbonate to be added into the modification tank 1. A discharge pipe 18 is installed at the bottom of the modification tank 1, extending into the tank, allowing the modified ultrafine heavy calcium carbonate to be discharged. A valve 19 is installed on the discharge pipe 18, which can be used to control the opening and closing state of the discharge pipe 18.
[0031] A rotating tube 3 is rotatably connected to the middle of the sealing cap 2. A dispersion cylinder 4 is sealed and fixedly installed at the bottom of the rotating tube 3. Dispersion holes 5 are equidistantly opened on the outer side of the dispersion cylinder 4. A fixed shaft 6 is installed at the top of the inner wall of the dispersion cylinder 4, and a spiral blade 7 is installed on the outer side of the fixed shaft 6. When the dispersion cylinder 4 rotates, it can drive the fixed shaft 6 and the spiral blade 7 to rotate together. The spiral blade 7 can lift the ultrafine heavy calcium carbonate located at the bottom of the modified tank 1, so that it enters the interior of the dispersion cylinder 4, and then is dispersed and discharged through the dispersion holes 5 on the outer side of the dispersion cylinder 4.
[0032] In one aspect of this embodiment, a drive assembly is provided on the top of the sealing cover 2. The drive assembly is used to drive the rotating tube 3 and the dispersing cylinder 4 to rotate. The drive assembly includes a driven gear 8, a motor 9, and a driving gear 10. The driven gear 8 is mounted on the outside of the rotating tube 3. The motor 9 is mounted on the top of the sealing cover 2. The driving gear 10 is mounted on the output shaft of the motor 9, and the driving gear 10 is meshed with the driven gear 8. By operating the motor 9, the driving gear 10 can be driven to rotate, thereby driving the driven gear 8 and the rotating tube 3 to rotate, and further driving the dispersing cylinder 4 to rotate.
[0033] In one aspect of this embodiment, a feeding assembly is provided on the rotating tube 3 for introducing a modifier to the outside of the dispersion cylinder 4. The feeding assembly includes an inlet pipe 11, inlet holes 12, a rotary joint 13, and a suction pump 14. The inlet pipe 11 is equidistantly installed on the outside of the rotating tube 3 and located below the sealing cap 2. The inlet pipe 11 communicates with the interior of the rotating tube 3, allowing the modifier entering the interior of the rotating tube 3 to enter the interior of the inlet pipe 11. The inlet pipe 11 has an L-shaped structure and is distributed on the outside of the dispersion cylinder 4, facilitating the modification of the dispersed ultrafine heavy calcium carbonate discharged by the dispersion cylinder 4. The inlet holes 12 are equidistantly opened on the outside of the inlet pipe 11, and each inlet hole 12 is equipped with a one-way valve. The one-way valve prevents the solution inside the modification tank 1 from entering the interior of the inlet pipe 11 through the inlet holes 12. The rotary joint 13 is fixedly installed on the top of the rotating tube 3, and the suction pump 14 is fixedly installed on the top of the sealing cover 2. The output end of the suction pump 14 is fixedly connected to the top of the rotary joint 13 through a pipe, and the input end of the suction pump 14 is connected to the external modifier container through a pipe. By using the operation of the suction pump 14, the modifier inside the external modifier container can be sucked out into the interior of the rotary joint 13, and then into the interior of the rotating tube 3 through the rotary joint 13. Finally, it is discharged through the inlet hole 12 on the inlet pipe 11. During use, due to the presence of the rotary joint 13, the pipe connected to the output end of the suction pump 14 will not rotate with the rotating tube 3.
[0034] Working principle:
[0035] When using, first place the modified tank 1 in the designated position and power on the equipment. Then, install the sealing cover 2 on the top of the modified tank 1, and at the same time, let the electric heating tube 16 extend into the heating tank 15. Then, electrically connect the motor 9, the suction pump 14 and the electric heating tube 16 to the external control equipment to facilitate the control of its operation. At the same time, connect the input end of the suction pump 14 to the external modified agent container through the pipe.
[0036] Then, ultrafine heavy calcium carbonate is added into the interior of the modified tank 1 through the feeding funnel 17. After the addition is completed, the motor 9, suction pump 14 and electric heating tube 16 are controlled by external control equipment to work simultaneously.
[0037] When the motor 9 is working, it drives the drive gear 10 to rotate, which in turn drives the driven gear 8 and the rotating tube 3 to rotate, which in turn drives the dispersion cylinder 4 to rotate. When the dispersion cylinder 4 rotates, it drives the fixed shaft 6 and the spiral blade 7 to rotate together. The spiral blade 7 can lift the ultrafine heavy calcium carbonate located at the bottom of the modified tank 1 and make it enter the interior of the dispersion cylinder 4, and then disperse and discharge it through the dispersion hole 5 on the outside of the dispersion cylinder 4.
[0038] Meanwhile, the rotating tube 3 drives the connected inlet tube 11 to rotate, and the suction pump 14 draws the modifier from the external modifier container into the rotating joint 13, and through the rotating joint 13 it enters the rotating tube 3. Finally, it is discharged through the inlet hole 12 on the inlet tube 11, so that the dispersed ultrafine heavy calcium carbonate can be better mixed with the introduced modifier, thereby ensuring the modification effect of the equipment on ultrafine heavy calcium carbonate, which is beneficial to practical application and operation. At the same time, the electric heating tube 16 can evenly heat the ultrafine heavy calcium carbonate material, making the ultrafine heavy calcium carbonate powder dry and less prone to agglomeration during the modification process.
[0039] After the modification is completed, open valve 19 and discharge the modified ultrafine heavy calcium carbonate through discharge pipe 18.
