Description

Technical Field

[0001] The invention relates to the technical field of chemical material mixing and stirring, in particular to a chemical material mixing and stirring tank. Background Art

[0002] In the field of chemical material mixing and stirring technology, existing mixing and stirring equipment has many problems when processing solid powders. These problems limit the mixing and stirring effect and the efficiency and quality of related chemical production.

[0003] Traditional mixing equipment for solid powders uses a relatively simple mixing method. It typically relies on simple circular rotation of rotating blades, resulting in limited horizontal mixing of the solid powder within the tank, making it difficult to achieve three-dimensional, thorough mixing. This results in the solid powder easily agglomerating, which in turn affects its reactivity.

[0004] During the mixing process, vortices rotating in the same direction are prone to form within the tank. When these vortices appear, the relative motion efficiency of the particles within the solid powder is significantly reduced. Because the vortices cause the solid powder to move in a specific direction, the particles are more likely to agglomerate, further hindering the uniformity of the mixing and resulting in poor mixing results. Summary of the Invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 4 As shown;

[0036] A chemical material mixing and stirring tank, comprising:

[0037] Tank 1;

[0038] A motor 11, wherein the motor 11 is fixedly connected to the lower end of the tank body 1, and the output shaft of the motor 11 extends into the interior of the tank body 1;

[0039] The main shaft 12 is rotatably connected to the interior of the tank body 1, with its lower end rigidly connected to the output shaft of the motor 11 and its upper end rotatably connected to the upper end of the tank body 1 via a spring assembly 25. The middle portion of the main shaft 12 is composed of three rigid shaft sections alternately connected to the coil spring 25 to form an axial elastic compensation structure. The three shaft sections are an upper shaft section 121, a middle shaft section 122, and a lower shaft section 123.

[0040] Rotating plates 13, the rotating plates 13 are respectively connected to the upper shaft body and the lower shaft body in the middle of the main shaft 12, and the rotating plates 13 are three in each group and are evenly distributed circumferentially around the central axis of the main shaft 12;

[0041] A fixed plate 14, the fixed plate 14 is evenly fixed to the inner wall of the tank body 1, and one end of the fixed plate 14 close to the main shaft 12 is rotatably connected to the outer ring surface of the middle shaft body 122 through a collar, and the fixed plate 14 is located between adjacent rotating plates 13;

[0042] An adding unit 2, the adding unit 2 is provided on the tank body 1, and the adding unit 2 is used to add additives into the tank body 1;

[0043] During use, a mixture of solid powder and water is placed into the mixing tank through a feed pipe at the upper end of the tank body 1, and then the motor 11 is rotated, which drives the main shaft 12 to rotate. Since the lower end of the main shaft 12 is rigidly connected to the output shaft of the motor 11, its upper end is rotatably connected to the upper end of the tank body 1 through a spring assembly 25, and the middle part of the main shaft 12 is composed of three rigid shafts (upper shaft 121, middle shaft 122 and lower shaft 123) alternately connected with the coil spring 25 to form an axial elastic compensation structure.

[0044] When the main shaft 12 rotates under the drive of the motor 11, the spring assembly 25 and the coil spring 25 in the middle of the main shaft 12 play a key role; the spring assembly 25 can not only buffer the vibration generated by the operation of the motor 11, reduce the impact on the tank body 1 and other components, and ensure the stability of the equipment operation; more importantly, the spring itself can be deformed in the up and down directions.

[0045] When the main shaft 12 rotates, the vertical deformation of the spring is transmitted to the connected rotating plate 13. Because the rotating plate 13 is respectively connected to the upper shaft 121 and the lower shaft 123 in the middle of the main shaft 12, the rotating plate 13 can simultaneously rotate in a circular manner with the main shaft 12 while also achieving a certain degree of vertical movement under the action of the spring. This unique combination of circular rotation and vertical movement enables the rotating plate 13 to more fully and three-dimensionally stir the mixture of solid powder and water in the tank.

[0046] The fan blade structure of the rotating plate 13 can disperse and stir the mixture of solid powder and water at different heights and levels during the up and down movement, breaking the limitations of traditional single circular rotation and allowing the solid powder to mix and contact with water and additives more fully, thereby achieving better mixing and dilution effects;

[0047] The rotating plate 13 disperses the solid powder inside the tank 1. When large or small particles of the solid powder agglomerate, the agglomerated particles are broken up by the stirring action generated by the rotation of the rotating plate 13, thereby preventing the particles inside the solid powder from agglomerating and thus preventing uneven distribution of the solid powder.

[0048] When the rotating plate 13 rotates, one end of the fixed plate 14 inside the tank body 1 is fixedly connected to the inner wall of the tank body 1, and the other end is rotatably connected to the main shaft 12, so that when the main shaft 12 rotates, the fixed plate 14 remains stationary, and further, when the rotating plate 13 rotates, the fixed plate 14 blocks the mixture formed by the solid powder and water; therefore, when the rotating plate 13 rotates, the fixed plate 14 disrupts the vortex generated by the rotating plate 13 in the mixture formed by the solid powder and water, thereby avoiding the formation of a vortex rotating in the same direction inside the tank body 1, resulting in a decrease in the efficiency of the relative movement of the particles inside the solid powder, thereby avoiding the agglomeration of the particles inside the solid powder, resulting in poor reaction performance of the solid powder, and the addition unit 2 inside the tank body 1 is used to add a small amount of additives to the mixture formed by the solid powder and water.

[0049] As a specific embodiment of the present invention, the adding unit 2 includes:

[0050] A first pipe 21, the first pipe 21 is evenly fixed to the inner wall of the tank body 1, the first pipe 21 contains additives, the first pipe 21 is located below the rotating plate 13 at the lower end, and there is a gap between the first pipe 21 and the main shaft 12;

[0051] A first slider 22 is slidably connected to the inside of the first tube 21 via a return spring, and an end of the first slider 22 close to the main shaft 12 extends out of the first tube 21;

[0052] A top block 23 , the top block 23 being fixedly connected to the outer ring surface of the main shaft 12 , and when the motor 11 rotates, the top block 23 presses the first slider 22 ;

[0053] A through hole 24 is provided on the upper end surface of the No. 1 pipe 21. A one-way valve is provided inside the through hole. A one-way water inlet valve is hingedly connected to the top wall of the No. 1 pipe 21.

[0054] The diameter of the through hole 24 gradually increases from top to bottom;

[0055] When in use, when the motor 11 drives the main shaft 12 to rotate, the main shaft 12 drives the top block 23 to move, and the top block 23 rotates with the main shaft 12. When the top block 23 rotates, the top block 23 and the No. 1 slider 22 extending out of the No. 1 tube 21 are squeezed. When the top block 23 squeezes the No. 1 slider 22, the No. 1 slider 22 moves toward the inside of the No. 1 tube 21, and the return spring inside the No. 1 tube 21 is compressed. When the No. 1 slider 22 slides inside the No. 1 tube 21, the No. 1 slider 22 squeezes the additive inside the No. 1 tube 21, and the one-way water inlet gate is closed. The additive inside the No. 1 tube 21 flows out from the through hole 24 at the upper end of the No. 1 tube 21, and passes through the one-way valve inside the through hole 24, so that the mixture of solid powder and water inside the tank body 1 cannot flow into the No. 1 tube 21. As the main shaft 12 rotates, the rotating plate 13 mixes and stirs the mixture formed by the solid powder and water, and in the process of dispersion, the additive is mixed with the solid powder, so that the additive is fully mixed;

[0056] And when the mixture of solid powder and water inside rotates with the rotating plate 13, the main body of the No. 1 tube 21 is in a stationary state, thereby disturbing the vortex formed by the mixture of solid powder and water in the lower part of the tank body 1, and further preventing the solid powder from agglomerating through the No. 1 tube 21; and by gradually increasing the aperture of the through hole 24 from top to bottom, when the No. 1 slider 22 slides in the No. 1 tube 21, the additive is sprayed out from the through hole 24. When the additive passes through the through hole 24, according to the narrow tube effect, the flow rate of the additive is faster when the additive is sprayed from the through hole 24, thereby making the impact force of the additive stronger, so that the contact between the additive and the solid powder is more sufficient.

[0057] As a specific embodiment of the present invention, one end of the rotating plate 13 is connected to a scraper 15. The scraper 15 is made of magnetic material and can form adsorption with the tank body 1, ensuring that the rotating plate 13 drives the scraper 15 to rotate horizontally and stably; one side of the scraper 15 is fixedly connected to a guide block 151, which is used to converge the mixture formed by the solid powder and water to the middle; the surface of the scraper 15 close to the main shaft 12 is evenly fixed with a guide plate 16; the guide plate 16 is set in an arc shape, and is used to guide the mixture formed by the solid powder and water inside the tank body 1 to roll upward;

[0058] When in use, a scraper 15 is fixedly connected to the end of the rotating plate 13 away from the main shaft 12, so that 15 is made of magnetic material and can form adsorption with the tank body 1, ensuring that the rotating plate 13 drives the scraper 15 to rotate horizontally and stably. When the motor 11 rotates, the motor 11 drives the main shaft 12 to rotate. When the main shaft 12 rotates, the main shaft 12 drives the rotating plate 13 to rotate inside the tank body 1, and the rotating plate 13 drives the scraper 15 to rotate. When the rotating plate 13 rotates, the rotating plate 13 causes the mixture of solid powder and water inside the tank body 1 to form a vortex, generating centrifugal force, and the solid powder is gathered to the inner wall of the tank body 1. When the scraper 15 rotates, the scraper 15 scrapes the inner wall of the tank body 1, thereby preventing the solid powder from adhering to the inner wall of the tank body 1 and agglomerating.

[0059] When the scraper 15 is scraping, the solid powder scraped off by the scraper 15 is guided by the guide block 151 to the middle and gathered. In the process of the solid powder being guided to the middle by the guide block 151, the solid powder scraped off by the scraper 15 is broken up, thereby preventing the solid powder adhering to the inner wall of the tank body 1 from agglomerating. In addition, the scraper 15 further increases the mixing efficiency of the solid powder inside the tank body 1.

[0060] Furthermore, by fixing a guide plate 16 to one end of the scraper 15 near the main shaft 12, when the rotating plate 13 rotates, the guide plate 16 scrapes off the solid powder dispersed to the inner wall of the tank body 1 by the centrifugal force, thereby further preventing the solid powder from adhering to the inner wall of the tank body 1 and agglomerating, thereby improving the mixing degree of the solid powder. Moreover, by making the guide plate 16 arc-shaped, when the rotating plate 13 rotates, the guide plate 16 rotates. When the guide plate 16 rotates, the guide plate 16 causes the mixture of solid powder and water inside the tank body 1 to roll upward from bottom to top, further promoting the additive below to flow upward and mix with the mixture of solid powder and water flowing downward from top to bottom, thereby increasing the mixing efficiency of the additive with the mixture of solid powder and water. During the mixing and stirring process, under the reverse action of the liquid, the guide plate 16 will be subjected to the upward or downward force of the liquid, and with the cooperation of the coil spring 25, the guide plate 16 is moved in the vertical direction to scrape off the solid powder at different positions inside the tank body 1.

[0061] As a specific embodiment of the present invention, the rotating plate 13 is configured to be in the shape of a fan blade;

[0062] When in use, the rotating plate 13 is configured as a fan blade, so that when the motor 11 rotates, the motor 11 drives the main shaft 12 to rotate. When the main shaft 12 rotates, the main shaft 12 drives the rotating plate 13 to rotate. The rotating plate 13 is configured as a fan blade. When the rotating plate 13 rotates, the mixture formed by the solid powder and water rolls. When the rotating plate 13 rotates, the rotating plate 13 causes the mixture formed by the solid powder and water to surge upward, thereby causing the additive at the lower end to move upward, thereby increasing the mixing efficiency of the additive and the solid powder, thereby improving the reaction efficiency of the additive.

[0063] As a specific embodiment of the present invention, the motor 11 is a forward and reverse motor 11;

[0064] During use, by rotating the motor 11 forward and reversely, when the motor 11 rotates clockwise, the motor 11 drives the rotating plate 13 to rotate, and the rotating plate 13 drives the mixture of solid powder and water inside the tank body 1 to rotate clockwise. When the rotating plate 13 rotates clockwise, the fixed plate 14 remains stationary, so that the fixed plate 14 blocks the stirred solid powder, so that the solid powder cannot maintain clockwise movement, thereby avoiding the problem of particle agglomeration inside the solid powder. When the motor 11 rotates counterclockwise, the mixture of solid powder and water rotates clockwise, and the motor 11 rotates counterclockwise, thereby breaking up the rotation of the solid powder, thereby further avoiding the problem of particle agglomeration inside the solid powder, thereby improving the dispersion efficiency of the solid powder.

[0065] As a specific embodiment of the present invention, one end of the No. 1 pipe 21 passes through the inner wall of the tank body 1 and is located at the outer ring of the tank body 1. A water tank 17 is provided at one end of the No. 1 pipe 21 located at the outer ring of the tank body 1. The water tank 17 contains additives.

[0066] During use, one end of the No. 1 pipe 21 is passed through the inner wall of the tank body 1 and is located on the outer circle of the tank body 1. A water tank 17 is set at one end of the No. 1 pipe 21. When the additive inside the No. 1 pipe 21 is insufficient, the additive is added into the water tank 17 to ensure the supply of the additive inside the No. 1 pipe 21. The water tank 17 facilitates the addition of additives into the No. 1 pipe 21, thereby improving the use efficiency of the No. 1 pipe 21.

[0067] The fixing plate 14 is provided with grooves 18 on both sides thereof, the inner walls of which are spherical surfaces;

[0068] During use, when the motor 11 rotates, the motor 11 drives the main shaft 12 to rotate. When the main shaft 12 rotates, the main shaft 12 drives the rotating plate 13 to rotate. When the rotating plate 13 causes the mixture of solid powder and water inside the tank body 1 to form a vortex, the mixture of solid powder and water forming the vortex contacts the side of the fixed plate 14, and the mixture of solid powder and water enters the interior of the groove 18. Since the inner wall of the groove 18 is a spherical surface, the mixture of solid powder and water will generate a backflow in the groove 18, so that the mixture of solid powder and water hitting the groove 18 has an opposite movement direction to the mixture of solid powder and water forming a vortex in the outside world, thereby avoiding the formation of vortices with the same flow direction inside the tank body 1, avoiding the agglomeration phenomenon inside the solid powder, and thereby improving the dispersion efficiency of the solid powder.

[0069] The specific working process is as follows: the mixture of solid powder and water is transported to the mixing tank through the feed pipe at the upper end of the tank body 1 in a certain proportion; the solid powder and water are first mixed and stirred, and the motor 11 is started. The motor 11 begins to rotate, and its output shaft drives the main shaft 12 rigidly connected to it to rotate synchronously. Since the middle part of the main shaft 12 is formed by three sections of rigid shaft bodies and coil springs 25 alternately connected to form an axial elastic compensation structure, and the upper end is rotatably connected to the upper end of the tank body 1 through the spring assembly 25, during the rotation process, the spring assembly 25 and the middle coil spring 25 can buffer the vibration generated by the operation of the motor 11, reduce the impact on other parts of the equipment, and ensure operational stability. At the same time, the elastic effect of the spring enables the rotating plate 13 connected to the main shaft 12 to not only perform circular motion when it rotates, but also to move up and down to a certain extent in the vertical direction.

[0070] The rotating plates 13 rotate along with the main shaft 12 . The rotating plates 13 , which are three in each group and evenly distributed circumferentially around the central axis of the main shaft 12 , have fan structures that continuously stir the mixture of solid powder and water in the tank body 1 during rotation.

[0071] As the rotating plates 13 rotate, a key function is played by the fixed plate 14, which is fixed to the inner wall of the tank body 1. One end of the fixed plate 14 is pivotally connected to the outer surface of the main shaft 12 via a collar, positioned between adjacent rotating plates 13. As the main shaft 12 rotates, the fixed plate 14 remains stationary. The fixed plate 14 and the rotating plates 13 move in opposite directions, disrupting the vortex generated by the rotating plates 13 in the mixture of solid powder and water, thus preventing the formation of co-rotating vortices within the tank body 1. This ensures a high level of relative motion efficiency among the solid powder particles, further preventing particle agglomeration.

[0072] Adding unit 2 inside tank 1 begins operating. As motor 11 rotates spindle 12, top block 23 on spindle 12 rotates accordingly. This rotation squeezes slider 22, which extends out of tube 21. Slider 22 slides within tube 21, squeezing the additive, forcing it out through hole 24 on the top end of tube 21, which is fitted with a one-way valve. Because hole 24 gradually increases in diameter from top to bottom, the additive flows out at a faster rate and with greater force, thanks to the constriction effect. This allows the additive to mix thoroughly with the solid powder and water mixture, improving mixing efficiency.

[0073] The scraper 15 fixedly connected to one end of the rotating plate 13 away from the main shaft 12 is made of magnetic material and adsorbs to the inner wall of the tank body 1, so it can rotate stably horizontally with the rotating plate 13. During the rotation process, the scraper 15 scrapes off the solid powder that may be attached to the inner wall of the tank body 1 to prevent it from agglomerating against the wall. The drainage block 151 on one side of the scraper 15 guides the scraped solid powder to converge in the middle of the tank body. At the same time, the arc-shaped guide plate 16 fixedly connected to the surface of the scraper 15 close to the main shaft 12 guides the mixture of solid powder and water inside the tank body 1 to roll upward during rotation, promoting the full mixing of the additives below with the mixture of solid powder and water flowing from top to bottom, further improving the mixing efficiency.

[0074] If the motor 11 is in forward and reverse rotation mode, alternating forward and reverse rotation can further disrupt the rotation of the solid powder and prevent particle agglomeration. The first pipe 21 is located at one end of the outer ring of the tank body 1 and is connected to the water tank 17. This can replenish the additives in the first pipe 21 in a timely manner to ensure that the dilution operation continues. The inner walls of the fixed plate 14 are spherical grooves 18. When the mixture of solid powder and water forms a vortex and contacts the side of the fixed plate 14, the grooves 18 cause the incoming mixture of solid powder and water to reflux in the opposite direction of the movement of the mixture of solid powder and water in the external vortex, disrupting the vortex again and preventing agglomeration.
