Description

Technical Field

[0001] This utility model relates to the field of nano-calcium carbonate technology, specifically to a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate. Background Technology

[0002] To fully utilize the nano-effect of nano-calcium carbonate, effective modification processes and surface modification methods must be employed to enhance its surface and broaden its application areas. Dry surface modification involves adding a modifier to nano-calcium carbonate powder and thoroughly mixing it using a stirring device to achieve surface modification. This method is simple, offers flexible formulation control, and allows for the integration of calcium carbonate surface treatment with downstream processes. The dry modification process requires rapid stirring to ensure the coupling agent quickly coats each calcium carbonate particle, and a suitable modification temperature to facilitate the coating reaction and achieve the desired surface modification.

[0003] According to the published information on a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate (publication number: CN215139001U), the above application operates through an external controller, which is simple to operate. The built-in heating wire around the tank can effectively control the modification temperature. The setting of multiple sets of stirrers can improve the mixing uniformity of the modifier and nano-calcium carbonate powder. Although the above method has multiple sets of stirrers, the stirring direction is relatively singular. Therefore, during the mixing process, it is easy to have the problem of mixing dead zones, resulting in uneven mixing. In order to address this problem, we propose a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate. Utility Model Content

[0004] The purpose of this invention is to provide a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate, comprising a mixing tank, a motor fixedly mounted on the top of the mixing tank, the output shaft of the motor being fixedly connected to the top of a stirring rod, and a control component provided inside the mixing tank, the control component comprising:

[0006] A crossbar, which is connected to a cone block via a support plate;

[0007] The oscillating component is used to promote material mixing. When the fixed block in the mixing tank abuts against the crossbar, the crossbar can drive the support plate to move laterally within the connecting plate. When the support plate moves, the surface of the support plate can move laterally synchronously through the inclined plate connected to the crossbar. The surface of the inclined plate has multiple sets of through holes, which can break the conventional flow pattern of materials during the mixing process and avoid uneven mixing due to excessively high local particle concentration.

[0008] Preferably, a support plate is fixedly installed on the side of the crossbar, and a cone block is fixedly installed on the side of the support plate. When the crossbar moves, the support plate fixed to the surface of the crossbar can move laterally synchronously within the connecting plate.

[0009] Preferably, the swinging component includes a spring, one end of which is fixedly mounted on the side of the support plate, and the other end of which is fixedly mounted on the inner wall of the connecting plate. The connecting plate is penetrated by a crossbar and slidably connected to the crossbar. When the crossbar is no longer in contact with the crossbar, the support plate can bounce up under the support of the spring.

[0010] Preferably, the inner wall of the connecting plate is fixedly equipped with a conical spike, and the connecting plate is fixedly installed on the arc surface of the stirring rod. When the stirring rod rotates, the connecting plate can perform a circular motion synchronously.

[0011] Preferably, the side of the support plate is fixedly connected to one end of the cross block, and the other end of the cross block is fixedly installed on the side of the inclined plate. When the support plate moves, the cross block fixed to the surface of the support plate can drive the inclined plate to move synchronously.

[0012] Preferably, the inclined plate has through holes, the inclined plate is inclined, and multiple sets of through holes are provided, so the mixing path can be changed during rotation.

[0013] Preferably, a fixing block is fixedly installed on the inner wall of the mixing tank. The fixing block inside the mixing tank can cause the crossbar to move when it comes into contact with the cross-section of the crossbar.

[0014] Compared with the prior art, this utility model provides a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate, which has the following beneficial effects:

[0015] 1. The stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate is equipped with a control component. When the output shaft of the motor drives the stirring rod to rotate, the connecting plate fixed on the surface of the stirring rod can rotate synchronously. When the fixed block in the mixing tank abuts against the crossbar, the crossbar can drive the support plate to move laterally within the connecting plate. When the support plate moves, the inclined plate connected to the crossbar on the surface of the support plate can move laterally synchronously. The surface of the inclined plate has multiple sets of through holes, which can break the conventional flow pattern of materials during the stirring process and avoid uneven mixing caused by excessively high local particle concentration.

[0016] 2. The stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate is equipped with a swinging component. During the lateral movement of the crossbar, the support plate fixed on the surface of the crossbar can drive the cone block to move in the direction of the cone spike, thereby squeezing and breaking up the agglomerates, further dispersing the nano-calcium carbonate particles and improving their uniformity in the mixing system.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a stirring and mixing device for heat-resistant surface modification of nano-calcium carbonate, including a mixing tank 1. A motor 3 is fixedly installed on the top of the mixing tank 1. The output shaft of the motor 3 is fixedly connected to the top of the stirring rod 2. A control component 4 is provided inside the mixing tank 1. The control component 4 includes: a crossbar 41, a support plate 42, a cone block 43, and a swinging component 44. When the fixed block 447 inside the mixing tank 1 abuts against the crossbar 41, the crossbar 41 can drive the support plate 42 to move laterally within the connecting plate 442. When the support plate 42 moves, the inclined plate 445 connected to the crossbar 444 on the surface of the support plate 42 can move laterally synchronously. The surface of the inclined plate 445 has multiple sets of through holes 446, which can break the conventional flow pattern of materials during the stirring process and avoid uneven mixing due to excessively high local particle concentration.

[0023] A support plate 42 is fixedly installed on the side of the crossbar 41, and a cone block 43 is fixedly installed on the side of the support plate 42. When the crossbar 41 moves, the support plate 42 fixed to the surface of the crossbar 41 can move laterally synchronously within the connecting plate 442. The swinging component 44 includes a spring 441. One end of the spring 441 is fixedly installed on the side of the support plate 42, and the other end of the spring 441 is fixedly installed on the inner wall of the connecting plate 442. The connecting plate 442 is penetrated by the crossbar 41 and is slidably connected to the crossbar 41. When the cross section of the crossbar 41 is no longer in contact, the support plate 42 can spring up under the support of the spring 441. A cone 443 is fixedly installed on the inner wall of the connecting plate 442. The connecting plate 442 is fixedly installed on the arc surface of the stirring rod 2. When the stirring rod 2 rotates, the connecting plate 442 can move in a circular motion synchronously. The side of the support plate 42 is fixedly connected to one end of the cross block 444, and the other end of the cross block 444 is fixedly installed on the side of the inclined plate 445. When the support plate 42 moves, the cross block 444 fixed to the surface of the support plate 42 can drive the inclined plate 445 to move synchronously. The inclined plate 445 has through holes 446. The inclined plate 445 is inclined and has multiple sets of through holes 446, so the mixing path can be changed during rotation. The inner wall of the mixing tank 1 is fixedly installed with a fixing block 447. The setting of the fixing block 447 in the mixing tank 1 can cause the cross bar 41 to move when it comes into contact with the tangential surface of the cross bar 41.

[0024] In this invention, during use, the modifier and nano-calcium carbonate powder to be mixed are poured into the mixing tank 1 through the feed pipe. After placement, the motor 3 at the top of the mixing tank 1 is started. The output shaft of the motor 3 drives the stirring rod 2 to rotate. When the stirring rod 2 rotates, the modifier and nano-calcium carbonate powder can be mixed. During the rotation of the stirring rod 2, the connecting plate 442 fixed to the surface of the stirring rod 2 can rotate synchronously. When the fixing block 447 in the mixing tank 1 abuts against the crossbar 41, the crossbar 41 can drive the support plate 42 to move laterally within the connecting plate 442. 2. During the movement, the inclined plate 445 connected to the support plate 42 via the cross block 444 can move laterally in sync. The inclined plate 445 has multiple sets of through holes 446 on its surface, which can break the conventional flow pattern of materials during the mixing process and avoid uneven mixing due to excessively high local particle concentration. During the lateral movement of the cross bar 41, the support plate 42 fixed to the surface of the cross bar 41 can drive the cone block 43 to move in the direction of the cone spike 443, squeezing and breaking the agglomerates, further dispersing the nano-calcium carbonate particles and improving their uniformity in the mixing system.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
