DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0029] like Figure 1-5As shown, the production device and the collection device are included. The production device includes a stirring tank body 10, a base 20, an upper cover 30 and a stirring group 40. The base 20 is located at the bottom and placed on the ground. The stirring tank body 10 is installed on one end face of the base 20 through an end face bearing 103. Support frames 101 are symmetrically arranged on both sides of the stirring tank body 10. The support frames 101 on both sides can play a supporting role. Moreover, through the arrangement of the end face bearing 103, the stirring tank body 10 and the base 20 are in a state of relative rotation, and various outlets and inlets on the stirring tank body 10 can be adjusted. The position of the opening can adapt to the use requirements of different environments, and the support frame 101 can also rotate to the side away from the mixing tank body 10, so that the supporting force it receives is completely on the end bearing 103. At this time, the mixing tank body can be rotated by pulling 101. When it is rotated to the corresponding position, the support frame 101 can be put down vertically to support part of the weight of the mixing tank body 10, so that it can support a part of the tank body instead of the end bearing 103. On the one hand, it can be used to limit the mixing tank body 10 from continuing to rotate so that it is limited. On the other hand, the end bearing 103 The mixing tank body 10 is easily damaged by the weight of the mixing tank body 10 for a long time. The support frame 101 can protect the end bearing 103, which greatly prolongs its service life. The upper cover 30 is installed on the mixing tank body 10 by bolts 302. A storage chamber 303 is fixed in the middle of the upper cover 30. A secondary grinding disc 304 is fixed at the bottom of the storage chamber 303. The storage chamber 303 and the secondary grinding disc 304 are hollow in the middle. A feeding pipe 301 is arranged in the storage chamber 303, wherein the feeding pipe 301 is connected to a feeding machine for receiving calcium carbonate raw materials. The mixing group 40 is arranged In the stirring tank body 10 and the base 20, the stirring group 40 includes a motor 403 and a rotating shaft 401 on the motor 403. The rotating shaft 401 penetrates the base 20 to the stirring tank body 10. At least two stirring rods 404 are also provided on the rotating shaft 401. The stirring rods 404 are located on the side close to the base 20. A main grinding disc 402 is fixed to the top of the rotating shaft 401. The main grinding disc 402 cooperates with the auxiliary grinding disc 304 to grind larger calcium carbonate raw materials into smaller powdered calcium carbonate particles with a particle size less than 0.1um and a relatively uniform particle size.

[0030] The stirring tank body 10 is in an inverted trapezoidal shape, and an isolation plate 105 is fixed on the inner wall of the stirring tank body 10. The isolation plate 105 is also in an inverted trapezoidal shape. The auxiliary grinding disc 304 and the main grinding disc 402 are located in the isolation plate 105, which is convenient for the ground calcium carbonate to fall in the center so that it has less impact on the separation process. At the same time, the separated calcium carbonate will be isolated to avoid mutual influence between it and the ground calcium carbonate. A discharge port 104 and a feeding port are fixed on the outer peripheral side of the stirring tank body 10. The discharge port 104 and the feeding port are on the opposite side. The discharge port 104 is located at the isolation plate 105, and an auxiliary feeding block 102 is detachably installed on the feeding port. Various modifiers can be added through the feeding port for the modification process.

[0031] A discharge port 201 is provided inside the base 20, one end of the discharge port 201 is connected to the inside of the mixing tank body 10, and the other end is connected to the outside. A baffle 202 is slidably provided inside the base 20, and the baffle 202 is located at the discharge port 201. The remaining calcium carbonate after separation can be taken out through the discharge port 201 to facilitate the next use of the equipment.

[0032] Working principle: When in use, the calcium carbonate raw material is transported from the feed pipe 301 to the storage chamber 303, the equipment is started, and the motor 403 drives the rotating shaft 401 to rotate, which can drive the main grinding disc 402 to rotate, and then it can cooperate with the auxiliary grinding disc 304 to grind the calcium carbonate raw material. The size after grinding is generally between 400 mesh and 1200 mesh. Then, the ground calcium carbonate will fall on the isolation plate 105 along the edge of the main grinding disc 402, and then fall in the center at the bottom of the stirring tank body 10 through the restriction of the isolation plate 105. By removing the auxiliary adding block 102, other powder modifiers can be added inside, and then the rotation of the rotating shaft 401 will stir the calcium carbonate through the stirring rod 404, so that the calcium carbonate and the modifier are fully mixed to produce a reaction. Example 2

[0033] A separation component is also provided on the rotating shaft 401, and the separation component includes a lower turntable 405 and an upper turntable 406, wherein the lower turntable 405 is fixed on the rotating shaft 401, and the upper turntable 406 is movably connected to the rotating shaft 401, and a support spring 407 is movably installed between the upper turntable 406 and the lower turntable 405 through a movable plate, and the upper turntable 406 slides on the rotating shaft 401, and a plurality of protruding blocks are provided on the end surface of the upper turntable 406 opposite to the lower turntable 405, wherein an electromagnet 4051 is also installed on the end surface of the lower turntable 405, and the upper turntable A magnetic block is also provided on the end surface of 406 at a position corresponding to the electromagnet 4051. A battery may be provided in the lower turntable 405 or a wire may be provided in the rotating shaft 401 to supply power to the electromagnet 4051. The electromagnet 4051 may be used to absorb the magnetic block so that the upper turntable 406 and the rotating shaft 401 can rotate synchronously. In addition, both ends of the supporting spring 407 rotate relative to the upper turntable 406. Under normal conditions, the lower turntable 405 cannot drive the upper turntable 406 to rotate through the spring. After the upper turntable 406 and the lower turntable 405 are attached to each other, the raised blocks on the two restrain each other. The lower turntable 405 is in the position so that the lower turntable 405 can drive the upper turntable 406 to rotate. A separation fan is fixed on the outer peripheral side of the upper turntable 406. The separation fan includes a separation rod 4061 and a separation blade 4062. At least two separation rods 4061 and separation blades 4062 are provided. The separation blade 4062 is obliquely fixed on the separation rod 4061. The portion of the separation rod 4061 close to the separation blade 4062 is bent. The bent separation rod 4061 can make the airflow generated by the separation blade 4062 when rotating flow toward the inner wall edge of the mixing tank body 10 to avoid the flow of air. The calcium carbonate separated by the separation blade 4062 and the ground calcium carbonate meet in the air and influence each other. Through the setting of the separation fan, the stirring rod 404 and the main grinding disc 402, the equipment can stir while grinding. At the same time, after the upper turntable 406 and the lower turntable 405 are coordinated, grinding, stirring and separation can be carried out at the same time, achieving the effect of one machine with multiple uses. The previous use of multiple large-scale equipment can be reduced to the same equipment, reducing the number of powder transportation times, which can effectively reduce the powder content in the factory. At the same time, reducing the equipment can also greatly reduce the production cost.

[0034] The collecting device includes a collecting pipe 501 and a collecting block 50. A collecting fan 5011 is fixed inside the collecting pipe 501. The collecting fan 5011 blows air into the collecting block 50, which can generate a certain suction force on the connecting pipe 60 to absorb the calcium carbonate floating in the stirring tank 10. The collecting pipe 501 is connected to the discharge port 104 through the connecting pipe 60. A material guide trough 503 is opened inside the collecting block 50. A collecting bag 502 is fixed on the inner wall of the material guide trough 503. The inner wall corner of the material guide trough 503 is a round surface. The collecting bag 502 is provided with a plurality of air holes, through which the separated calcium carbonate can be collected. The collecting bag 502 can filter calcium carbonate and is breathable. By setting the collecting fan 5011 in the collecting device, a certain negative pressure can be generated at the discharge port 104, so that the calcium carbonate blown up by the separation blades 4062 can be absorbed, so as to achieve the purpose of separating calcium carbonate of different weights and make the quality of calcium carbonate more uniform and fine.

[0035] Working principle: When calcium carbonate powder needs to be separated, the modified calcium carbonate after the reaction will have different sizes and weights, and the difference is large. At this time, it is necessary to separate them and screen out the modified calcium carbonate with better quality. The electromagnet 4051 can be started to generate electricity to generate magnetism, adsorb the magnet on the upper turntable 406, and then the upper turntable 406 compresses the support spring 407 to cooperate with the lower turntable 405. At this time, the rotation of the rotating shaft 401 can also drive the upper turntable 406 to rotate through the lower turntable 405. The rotation of the upper turntable 406 can drive the separation fan to rotate, and because the separation rod 4061 The part is bent, and the airflow generated by the separation blade 4062 will blow the lighter modified calcium carbonate along the inner wall of the stirring tank body 10 to the outside of the isolation plate 105, close to the same plane of the discharge port 104, and be restricted by it. Then the suction force generated by the rotation of the collecting fan 5011 will absorb the modified calcium carbonate around the discharge port 104, and collect the particles with relatively uniform mass size into the guide trough 503, so as to achieve the separation effect. When the separation is completed, the modified calcium carbonate with larger mass size is taken out through the discharge port 201, so grinding, stirring and separation can be carried out at the same time, so as to achieve the multi-purpose effect of one machine. Example 3

[0036] The invention discloses modified calcium carbonate prepared by a stirring modified calcium carbonate preparation device. The modified calcium carbonate comprises 78 parts of heavy calcium carbonate powder, 8 parts of stearic acid and 12 parts of titanate. Example 4

[0037] The modified calcium carbonate is prepared by a stirring modified calcium carbonate preparation device. The modified calcium carbonate comprises 90 parts of heavy calcium carbonate powder, 10 parts of polymer emulsion powder and 12 parts of surfactant. Example 5

[0038] The modified calcium carbonate is prepared by a stirring modified calcium carbonate preparation device. The modified calcium carbonate comprises 90 parts of heavy calcium carbonate powder, 5 parts of eleostearic acid anhydride hydrolyzate, and 6 parts of polyethylene glycol.

[0039] In the above embodiments, the heavy calcium carbonate powder is directly mixed with various modifier powders in a dry environment and stirred. The modifier reacts with the surface of the calcium carbonate to produce a hydroxyl group to form an organic coating layer, thereby improving the compatibility and dispersibility of the calcium carbonate with the organism.

[0040] In summary, the stirring modified calcium carbonate preparation equipment, through the setting of the separation fan and the stirring rod 404 and the main grinding disc 402, enables the equipment to stir while grinding, and after the upper turntable 406 and the lower turntable 405 are matched, grinding, stirring and separation can be carried out at the same time, so as to achieve the effect of one machine with multiple uses, and reduce the previous use of multiple large-scale equipment to the same equipment, reduce the number of powder transportation times, and can effectively reduce the content of powder in the factory. At the same time, reducing the equipment can also greatly reduce the production cost; the separated calcium carbonate can be collected through the air vents, which can filter calcium carbonate and is breathable. By setting the collecting fan 5011 in the collecting device, a certain negative pressure can be generated at the discharge port 104, so that it can absorb the calcium carbonate blown up by the separation blades 4062, so as to achieve the purpose of separating calcium carbonate of different weights and make the quality of calcium carbonate more uniform and fine; the support frames 101 on both sides can support the stirring tank body 10, and the end bearings 103 are set to make the stirring tank body 10 and the base 20 in a state of relative rotation, so that the positions of various outlets and inlets on the stirring tank body 10 can be adjusted to adapt to the use requirements of different environments.
