Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate processing technology, and specifically relates to an activation machine for processing active calcium carbonate. Background Technology

[0002] Calcium carbonate activation is a process of surface modification of calcium carbonate powder using physical or chemical methods, often employing an activation machine. Its core function is to improve the compatibility of calcium carbonate with organic matter, thereby enhancing its performance in composite materials. Specifically, surfactants (such as coupling agents and fatty acids) are added, and under mechanical stirring and heating conditions, the modifier is uniformly coated onto the surface of the calcium carbonate particles, forming a monomolecular film that transforms the hydrophilic surface into a hydrophobic one. Continuous stirring of the calcium carbonate and surfactant is required during this process. In wet processes, calcium carbonate is typically mixed as a slurry, but its high density makes it prone to settling in the activation machine, and its poor fluidity necessitates longer stirring times and higher speeds for uniform mixing, resulting in a longer processing time. Utility Model Content

[0003] The purpose of this invention is to provide an activation machine for processing active calcium carbonate, which can introduce an upward-flowing airflow during the stirring process. The rising bubbles will disrupt the original laminar flow and form an upward flow. Combined with the stirring of mechanical agitation, it can counteract the sinking tendency of calcium carbonate due to its density and accelerate the mixing speed of calcium carbonate and modifier.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] An activation machine for processing activated calcium carbonate includes a base, an activation box mounted on top of the base, and a stirring mechanism installed inside the activation box.

[0006] The stirring mechanism includes a rotating platform, which is rotatably mounted at the bottom of the activation box. Several first stirring rods are mounted on the outside of the rotating platform, and several scrapers are fixed on one side of each first stirring rod. The rotating platform, the first stirring rods, and the second stirring rods are all hollow inside, and the top of each first stirring rod and scraper is fixed with a second stirring rod. An air pump is installed inside the base, which is used to inject air into the rotating platform, the first stirring rods, and the second stirring rods. Curved air pipes are installed on the top of each rotating platform and the second stirring rod.

[0007] Furthermore, a second pulley is fixed to the bottom of the rotary table. The middle of the second pulley is hollow. The second pulley is rotatably connected to the base. A motor is fixed to one end inside the base. A first pulley is fixed to the output end of the motor. A transmission belt is installed between the first pulley and the second pulley.

[0008] Furthermore, an air supply pipe is installed at the output end of the air pump, and an intermittent jet assembly is installed between the air supply pipe and the second pulley. The intermittent jet assembly includes a first pinion, which is fixed to the bottom of the second pulley and is also hollow inside. A first large gear is rotatably connected to one side of the first pinion, and a second pinion is fixed to the bottom of the first large gear. A second large gear is rotatably mounted to the other side of the second pinion, and a connecting pipe is fixed to the bottom of the second large gear.

[0009] The connecting pipe is rotatably connected to the air outlet of the air supply pipe. An air inlet pipe is provided between the second large gear and the first small gear. A first air inlet is provided at the bottom of the air inlet pipe, and a second air inlet is provided in the middle of the second large gear.

[0010] Furthermore, a mounting bracket is fixed inside the base, and a fixing plate is fixed in the middle of the top of the mounting bracket. One end of the fixing plate is fixed to the air intake pipe, and a rotating collar is fixed to the other end of the fixing plate. The first large gear and the second small gear are respectively rotatably mounted above and below the rotating collar.

[0011] Furthermore, a venting pipe is installed on the gas supply pipe.

[0012] Furthermore, a scraper is provided on the outer side of the first stirring rod and in contact with the inner liner of the activation box, and a discharge port is provided on one side of the activation box.

[0013] Furthermore, a top cover is installed on the top of the activation box, and a vacuum chamber is provided between the inner liner and the outer shell of the activation box. A heating wire is installed in the vacuum chamber and in contact with the inner liner of the activation box.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the linkage of an air pump, a first stirring rod, a second stirring rod, and a curved air tube, allows air to be injected during the stirring process, from which rising bubbles are blown out from the curved air tube, forming turbulence and pushing the sinking calcium carbonate upward. Combined with mechanical stirring, this reduces sedimentation, accelerates the contact and coating of calcium carbonate with the modifier, and increases the mixing speed and efficiency.

[0016] This invention achieves periodic air supply through the design of an intermittent jet assembly, causing the curved air pipe to blow out intermittent bubbles. Combined with mechanical stirring, this creates an irregular turbulence effect, further accelerating the mixing speed and efficiency. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1 to 5 As shown, an activation machine for processing activated calcium carbonate includes a base 1, an activation box 2 is installed on the top of the base 1, and a stirring mechanism 3 is installed inside the activation box 2.

[0026] The stirring mechanism 3 includes a rotating table 31, which is rotatably mounted on the bottom of the activation box 2. Several first stirring rods 32 are mounted on the outside of the rotating table 31. Several scrapers 33 are also fixed on one side of the first stirring rods 32. The rotating table 31, the first stirring rods 32 and the second stirring rods 34 are all hollow. The top of the first stirring rods 32 and the scrapers 33 are all fixed with the second stirring rods 34. An air pump 14 is installed inside the base 1. The air pump 14 is used to inject air into the rotating table 31, the first stirring rods 32 and the second stirring rods 34. Curved air pipes 35 are installed on the top of the rotating table 31 and the second stirring rods 34.

[0027] In the above process, calcium carbonate and modifier mixed into a slurry are added to the activation tank 2 in proportion, and the stirring mechanism 3 is controlled to rotate. During rotation, the first stirring rod 32 and the second stirring rod 34 can stir the calcium carbonate and modifier. At the same time, air can be delivered to the interior of the first stirring rod 32 and the second stirring rod 34 through the air pump 14 and blown out from the curved air pipe 35 to form rising bubbles, which push the deposited calcium carbonate at the bottom upward. In conjunction with the continuous disturbance of the rotating first stirring rod 32 and the second stirring rod 34, the uniformity and speed of mixing of calcium carbonate and modifier are accelerated.

[0028] Furthermore, a top cover 21 is installed on the top of the activation box 2, and a vacuum chamber 22 is provided between the inner liner and the outer shell of the activation box 2. An electric heating wire 23 is provided in the vacuum chamber 22 and in contact with the inner liner of the activation box 2. The electric heating wire 23 is used to heat the material during the mixing process. A scraper 33 is provided on the outer side of the first stirring rod 32 and in contact with the inner liner of the activation box 2. A discharge port is provided on one side of the activation box 2. The scraper 33 is used to continuously scrape the inner wall of the inner liner of the activation box 2 during the mixing process to avoid material residue. The discharge port is used to discharge the uniformly mixed activated calcium carbonate.

[0029] Please refer to the following: Figure 3 and Figure 4 As shown, a second pulley 38 is fixed at the bottom of the rotary table 31. The middle part of the second pulley 38 is hollow. The second pulley 38 is rotatably connected to the base 1. A motor 36 is fixed at one end inside the base 1. A first pulley 37 is fixed at the output end of the motor 36. A transmission belt 39 is installed between the first pulley 37 and the second pulley 38.

[0030] As described above, when the rotary table 31 rotates, the motor 36 drives the first pulley 37 to rotate, and the transmission belt 39 drives the second pulley 38 fixed at the bottom of the rotary table 31 to rotate, so that the first stirring rod 32 and the second stirring rod 34 can continuously stir the calcium carbonate and the modifier.

[0031] Please refer to it again. Figure 2As shown, an air supply pipe 15 is installed at the output end of the air pump 14. An intermittent jet assembly 4 is installed between the air supply pipe 15 and the second pulley 38. The intermittent jet assembly 4 includes a first pinion 41, which is fixed to the bottom of the second pulley 38. The interior of the first pinion 41 is also hollow. A first large gear 42 is rotatably connected to one side of the first pinion 41. A second pinion 43 is fixed to the bottom of the first large gear 42. A second large gear 44 is rotatably installed on the other side of the second pinion 43. A connecting pipe 46 is fixed to the bottom of the second large gear 44. The connecting pipe 46 is rotatably connected to the air outlet of the air supply pipe 15. An air inlet pipe 45 is provided between the second large gear 44 and the first pinion 41. A first air inlet 47 is provided at the bottom of the air inlet pipe 45. A second air inlet 48 is provided in the middle of the second large gear 44.

[0032] In the above description, the second pulley 38, while rotating, drives the first pinion 41 fixed below it to rotate. Under the action of meshing transmission, it drives the first large gear 42 and the second pinion 43 to rotate together. And under the action of meshing again, it drives the second large gear 44 to rotate. Since the size of the first large gear 42 and the second large gear 44 is larger than that of the first pinion 41 and the second pinion 43, after transmission, the rotational speed of the second large gear 44 is lower than that of the first pinion 41. Therefore, the second large gear 44 will only rotate once after the first pinion 41 rotates several times. For example, if the first pinion 41 rotates 3 times, it will drive the second large gear 44 to rotate. When the second large gear 44 rotates to the point where the second air inlet 48 aligns with the first air inlet 47, the air passage is connected, allowing air to enter the first stirring rod 32 and the second stirring rod 34. The air is blown out, accelerating the mixing speed and efficiency. When the second large gear 44 rotates to the point where the second air inlet 48 is misaligned with the first air inlet 47, air cannot enter the first stirring rod 32 and the second stirring rod 34, and the air stops blowing out. Through high-frequency, intermittent, short-duration air blowing out, high-frequency small and medium-sized bubbles rise, forming irregular turbulence. Combined with the turbulence of the first large gear 42 and the second large gear 44, the mixing rate can be further accelerated.

[0033] Furthermore, a mounting bracket 11 is fixed inside the base 1, and a fixing plate 12 is fixed in the middle of the top of the mounting bracket 11. One end of the fixing plate 12 is fixed to the air intake pipe 45, and a rotating collar 13 is fixed to the other end of the fixing plate 12. The first large gear 42 and the second small gear 43 are respectively rotatably mounted above and below the rotating collar 13.

[0034] As described above, the mounting bracket 11 is used to provide support for the installation of the first large gear 42, the second small gear 43 and the air intake pipe 45, so that the air intake pipe 45 is fixed and the second large gear 44 can be rotated to allow intermittent airflow.

[0035] Furthermore, the gas supply pipe 15 is equipped with a vent pipe, which is used to discharge excess gas and balance the pressure inside the gas supply pipe 15 when the first air inlet 47 and the second air inlet 48 are in a staggered state.

[0036] The working principle of this utility model is as follows: The material is put into the activation box 2 in proportion, and the stirring mechanism 3 is driven to rotate through the curved air pipe 35. During the process, the first stirring rod 32 and the second stirring rod 34 continuously stir the material to make the calcium carbonate and modifier evenly mixed. At the same time, the air pump 14 injects air into the first stirring rod 32 and the second stirring rod 34 and blows the air out from the curved air pipe 35 to form rising bubbles, which lift the deposited calcium carbonate at the bottom. Together with the rotation and stirring, the contact and coating of calcium carbonate and modifier are accelerated. While the air is introduced, the transmission speed is reduced by the meshing of the first small gear 41, the first large gear 42, the second small gear 43 and the second large gear 44, so that the rotation speed of the second large gear 44 is lower than the stirring speed. At the same time, the first air inlet 47 and the second air inlet 48 set on the air inlet pipe 45 of the second large gear 44 will be connected or closed according to the rotation angle of the second large gear 44 to achieve the purpose of intermittent air supply, forming intermittent rising bubbles, creating an irregular turbulence effect, which, together with the rotation and stirring, achieves a better mixing effect.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
