Description

Technical Field

[0001] The present invention relates to the technical field of stirrers, in particular to a solution mixing stirrer. Background Art

[0002] In many fields such as chemical industry, food, and pharmaceuticals, it is often necessary to mix powdered solids with liquids to form solutions. The solution system formed by the mixture of powdered solids and liquids is relatively complex and significantly different from general solutions. This type of solution faces many difficulties during the mixing process, which greatly affects the stirring effect and production efficiency.

[0003] Powdered solids have the characteristics of small particle size and large specific surface area. When they are mixed with liquids, they are very easy to clump together. This is because there are strong intermolecular forces between powdered solid particles. In a liquid environment, these particles are easily attracted to each other, forming agglomerates of different sizes. These agglomerates are difficult to be fully broken up during the stirring process, resulting in uneven distribution of the components in the solution, affecting the stability of product quality.

[0004] At the same time, powdered solids are prone to stick to the wall during the stirring process. When the stirrer is running, the powdered solid particles are affected by multiple forces such as gravity, liquid flow friction, and adhesion to the inner wall of the stirrer. During long-term stirring, the powdered solid particles gradually accumulate on the inner wall of the stirrer, forming a wall-sticking phenomenon. This will not only reduce the mixing efficiency of the stirrer and increase energy consumption, but also cause material waste. The residual powdered solids may contaminate subsequent batches of products, affecting the purity and quality of the products.

[0005] Currently, existing agitators have difficulty in effectively solving the problem of powdered solids clumping and adhering to the wall when processing solutions of powdered solids and liquids. Since different particles are subjected to different centrifugal forces, the powdered solids cannot be evenly dispersed in the liquid, resulting in uneven mixing of the solution. The problem of adhesion to the inner wall of the agitator also increases the cleaning and maintenance costs of the agitator, further reducing production efficiency and restricting the development of related industries.

[0006] In view of this, the present invention proposes a solution mixing agitator to solve the above problems. Summary of the Invention

[0007] In order to make up for the defects of the existing technology in processing mixed solutions of powdered solids and liquids, and solve the problem that when the existing agitator stirs such solutions, the powdered solids are very easy to clump together, and the difference in centrifugal force exerted on different particles makes it difficult for them to be evenly dispersed in the liquid, thereby causing uneven mixing of the solution; at the same time, it solves the problem that the powdered solids are easy to adhere to the inner wall of the agitator, and the long-term accumulation leads to molecular accumulation and particle agglomeration, which not only reduces the efficiency of the agitator, but also increases the cleaning and maintenance costs and affects the product quality; the present invention proposes a solution mixing agitator.

During stirring, the slave shaft rotates with the main shaft and expands outward under the action of centrifugal force, and the stirring and mixing operation of the solution is achieved through the stirring rods.

[0012] Stirring rods are evenly distributed on the shaft and are divided into three layers: upper, middle, and lower. The stirring rods on the upper layer can drive the rotating plate to rotate. The stirring rods on the middle layer intermittently contact the rotating plate to achieve vibration when stirring the middle material. The stirring rods on the lower layer cooperate with the spiral blades to stir the solution near the bottom of the cylinder;

[0013] An annular block, the annular block is slidably connected to the inner wall of the cylinder through a sliding groove;

[0014] A rotating plate is fixedly connected to the annular block, and one side of the rotating plate is an arc-shaped guide surface, which is used to remove materials on the inner wall of the cylinder and realize the convergence of the materials to the middle of the cylinder;

[0015] Preferably, the stirring rods are hinged to the slave shafts respectively through rotating shafts, and the stirring rods are able to swing up and down around the hinge points, and the lengths of the stirring rods in the upper and middle layers are greater than the minimum distance between the slave shafts and the rotating plate after being extended outwards;

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The arc-shaped guide surface of the rotating plate will scrape the inner wall of the cylinder during the rotation process, preventing the wall adhesion caused by molecular accumulation and particle agglomeration, ensuring the continuous and efficient operation of the agitator and extending the service life of the equipment.

[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 solution mixing agitator, comprising: a cylinder 1,

[0037] Spiral blades 2, wherein the plurality of spiral blades 2 are arranged in an inverted cone shape, with the upper blades being larger and the lower blades being smaller, and becoming smaller from top to bottom. The spiral blades 2 are fixedly connected to the bottom of the main shaft 3 and are used to transport the material at the bottom of the cylinder 1 to the middle of the cylinder 1;

[0038] The main shaft 3 is arranged from top to bottom, with its bottom end fixedly connected to the motor output shaft at the center of the bottom outer side. The part of the bottom that fixes the spiral blade 2 is a whole shaft, and the upper part is connected to the slave shaft 4, which is used to transmit the power of the motor to drive the spiral blade 2 and the slave shaft 4 to rotate;

[0039] There are three slave shafts 4, each made of a material with a certain toughness, such as a spring steel bar or a composite fiber rod. The bottom of the slave shaft 4 is firmly connected to the upper part of the main shaft 3. Each slave shaft 4 is evenly provided with three layers of stirring rods 5 from top to bottom. During stirring, the slave shaft 4 rotates with the main shaft 3 and opens outward under the action of centrifugal force, and the stirring and mixing operation of the solution is achieved through the stirring rods 5;

[0040] Stirring rods 5 are evenly distributed on the shaft 4 and are divided into three layers: upper, middle, and lower. The stirring rods 5 on the upper layer can drive the rotating plate 14 to rotate. The stirring rods 5 on the middle layer intermittently contact the rotating plate 14 to achieve vibration when stirring the middle material. The stirring rods 5 on the lower layer cooperate with the spiral blades 2 to stir the solution near the bottom of the cylinder 1;

[0041] An annular block 13, the annular block 13 is slidably connected to the inner wall of the cylinder 1 through a sliding groove 131;

[0042] The rotating plate 14 is fixedly connected to the annular block 13. One side of the rotating plate 14 is an arc-shaped guide surface 141. The arc-shaped guide surface 141 is used to remove materials on the inner wall of the cylinder 1 and realize the materials to converge to the middle of the cylinder 1.

[0043] When in use, the solution is placed into the cylinder 1 through the feed port at the upper end of the cylinder 1. After placement is completed, the servo motor is started, and the servo motor changes speed and rotates. The servo motor controls the main shaft 3 to rotate. When the main shaft 3 rotates, the spiral blade 2 at the bottom is driven to rotate together. The spiral blade 2 transports the material at the bottom of the cylinder 1 upward along the inverted cone wall of the cylinder 1 to the middle of the cylinder 1. At the same time, the main shaft 3 drives the three slave shafts 4 connected thereto to rotate. Since the slave shaft 4 is elastic, the three slave shafts 4 are opened outward under the action of centrifugal force. After the slave shaft 4 is opened, the length of the top stirring rod 5 thereon is sufficient to push the rotating plate 14 to rotate. The rotating plate 14 slides in the slide groove 131 on the inner wall of the cylinder 1 through the annular block 13, and then rotates on the inner wall of the cylinder 1. When the rotating plate 14 rotates, the arc-shaped guide surface 141 on one side guides the internal mixed solution to the middle part. The solution guided to the middle of the cylinder 1 through the arc-shaped guide surface 141 collides with the stirring rod 5, thereby promoting solution mixing.

[0044] When the stirring rod 5 in the middle stirs the material in the middle, it will intermittently contact with the rotating plate 14 and generate vibrations, which helps to further break up the agglomerated particles in the solution and improve the uniformity of solution mixing. The stirring rod 5 in the lower layer cooperates with the spiral blade 2 to stir the solution near the bottom of the cylinder 1 to ensure that the bottom solution is fully mixed.

[0045] The solutions inside the cylinder 1 are mixed and stirred, so that the mixing between the solutions is more sufficient. When the mixed solution flows, the stirring rod 5 on the upper layer pushes one side of the rotating plate 14, and the rotating plate 14 is subjected to force and transmitted to the annular block 13, so that the annular block 13 slides in the slide groove 131 on the inner wall of the cylinder 1, thereby causing the rotating plate 14 to rotate on the inner wall of the cylinder 1, and when the rotating plate 14 rotates, the arc-shaped guide surface 141 on one side of the rotating plate 14 guides the internal mixed solution toward the middle, and the solution guided to the middle of the cylinder 1 by the arc-shaped guide surface 141 collides with the stirring rod 5, thereby causing the stirring rod 5 to mix the solutions on the inner wall of the cylinder 1, and when the rotating plate 14 rotates on the inner wall of the cylinder 1, the arc-shaped guide surface 141 on one side of the rotating plate 14 scrapes the inner wall of the cylinder 1, thereby avoiding the problem of the inner wall of the cylinder 1 sticking to the wall;

[0046] As a specific embodiment of the present invention, the stirring rods 5 are hinged to the slave shafts 4 through rotating shafts, and the stirring rods 5 can swing up and down around the hinge points. The lengths of the stirring rods 5 on the upper and middle layers are greater than the minimum distance between the slave shafts 4 and the rotating plate 14 after being extended outward.

[0047] When in use, by making the stirring rod 5 hinged to the slave shaft 4 through the rotating shaft, and making the length of the stirring rod 5 of the upper layer and the middle layer greater than the minimum distance between the slave shaft 4 and the rotating plate 14 after being extended outward, when the mixed solution inside the cylinder 1 is small, by controlling the speed of the motor at the center of the bottom outer side, when the motor drives the main shaft 3 to rotate, the main shaft 3 drives the slave shaft 4 to rotate. Since the stirring rod 5 and the slave shaft 4 are hinged through the rotating shaft, the centrifugal force on the stirring rod 5 is small when rotating, so that the inclination angle between the stirring rod 5 and the slave shaft 4 is small, and the contact depth of the stirring rod 5 with the inside of the solution is large when rotating, thereby making the stirring efficiency higher. When the liquid level inside is high, the rotation speed of the motor is increased, the centrifugal force exerted on the stirring rod 5 during rotation increases, and the inclination angle between the stirring rod 5 and the slave shaft 4 increases. Since the length of the stirring rods 5 in the upper and middle layers is greater than the minimum distance between the stirring rods 5 and the rotating plate 14 after being extended from the slave shaft 4, the stirring rods 5 in the upper and middle layers will contact the side of the rotating plate 14, and then when the stirring rods 5 rotate, they can push the rotating plate 14 to rotate. The rotating plate 14 slides in the chute 131 on the inner wall of the cylinder 1 through the annular block 13, thereby improving the scraping efficiency of the rotating plate 14 on the inner wall of the cylinder 1, and also making the solution mixed more fully.

[0048] As a specific embodiment of the present invention, the angle between the side surface of the rotating plate 14 corresponding to the arc-shaped guide surface 141 and the inner wall of the cylinder 1 is an acute angle;

[0049] A first groove 15 is evenly formed on one side of the rotating plate 14 corresponding to the arc-shaped guide surface 141, and a gasket is disposed in the first groove 15;

[0050] The blades 16 are evenly fixed on the arc-shaped guide surface 141;

[0051] When in use, by making the angle between the side surface corresponding to the arc-shaped guide surface 141 on the rotating plate 14 and the cylinder 1 be an acute angle, when the servo motor rotates, the main shaft 3 rotates, and the main shaft 3 drives the slave shaft 4 to rotate, and the stirring rod 5 on the slave shaft 4 rotates accordingly, and the stirring rod 5 stirs the mixed solution inside the cylinder 1, thereby mixing and stirring the mixed solution inside the cylinder 1, and causing the mixed liquid to impact the side surface corresponding to the arc-shaped guide surface 141 on the rotating plate 14. Since the angle between one side of the rotating plate 14 and the inner wall of the cylinder 1 is an acute angle, the resistance of the solution when impacting the rotating plate 14 increases, thereby increasing the power generated by the rotating plate 14, thereby increasing the effect of the rotating plate 14 scraping the inside of the cylinder 1, and The phenomenon of sticking to the wall is avoided; by opening a No. 1 groove 15 on the side corresponding to the rotating plate 14 and the arc-shaped guide surface 141, and arranging a gasket in the No. 1 groove 15, when the stirring rod 5 rotates and contacts the rotating plate 14, the stirring rod 5 enters the No. 1 groove 15, and the stirring rod 5 is buffered by the gasket, thereby avoiding the stirring rod 5 from colliding with the rotating plate 14, thereby improving the service life of the rotating plate 14 and the stirring rod 5; and by evenly arranging blades 16 on the arc-shaped guide surface 141, when the arc-shaped guide surface 141 of the rotating plate 14 scrapes the inner wall of the cylinder 1, the scraped solution, when passing through the arc-shaped guide surface 141, the part of the solution that sticks to the wall is broken by the blade 16, thereby increasing the mixing degree of the solution.

[0052] As a specific embodiment of the present invention, a spoiler 17 is hingedly connected to one side of the stirring rod 5;

[0053] The spoiler 17 is evenly provided with strip-shaped grooves 171;

[0054] When in use, a spoiler 17 is hinged on one side of the stirring rod 5. When the servo motor rotates, the main shaft 3 rotates, driving the slave shaft 4 and the stirring rod 5 to rotate, and the spoiler 17 also rotates accordingly. Since the spoiler 17 is hinged, and the mixed liquid flows unevenly inside the cylinder 1 when it is stirred, the mixed liquid will impact the spoiler 17 during the stirring process, and the spoiler 17 will swing, so that when the spoiler 17 swings, the spoiler 17 will stir the solution, thereby increasing the mixing efficiency of the solution, and when the rotating plate 14 flows inside the cylinder 1, the rotating plate 14 The arc-shaped guide surface 141 on the plate 14 causes the solution on the inner wall of the cylinder 1 to converge toward the middle. When the solution converges toward the middle, the solution impacts the spoiler 17, further increasing the swing efficiency of the spoiler 17. By providing a strip groove 171 on the spoiler 17, the surface roughness of the spoiler 17 is increased when the solution impacts the spoiler 17, so that when the spoiler 17 moves in the solution, the friction between the surface of the spoiler 17 and the solution is increased, thereby reducing the stability of the solution on the surface of the spoiler 17, thereby increasing the disturbance efficiency of the spoiler 17 on the solution.

[0055] As a specific embodiment of the present invention, a first post 18 is provided at one end of the spoiler 17 away from the stirring rod 5;

[0056] The first column 18 is rotatably connected to the spoiler 17 via a rotating shaft;

[0057] The outer ring of the first column 18 is uneven;

[0058] When in use, by arranging a No. 1 column 18 at the end of the spoiler 17 away from the stirring rod 5, when the stirring rod 5 rotates, the spoiler 17 rotates with the stirring rod 5. When the spoiler 17 rotates, the No. 1 column 18 at the end of the spoiler 17 away from the stirring rod 5 moves in the solution, and the solution impacts the outer circle of the No. 1 column 18, and by making the arc-shaped guide surface 141 on the rotating plate 14, the solution on the inner wall of the cylinder 1 converges to the middle. In the process of solution convergence, the flow of the solution will intermittently impact the No. 1 column 18, thereby making the No. 1 column 18 unstable, and then causing the spoiler 17 to swing, so that the spoiler 1 7 disturbs the solution, and by making the column No. 18 rotatably connected to the spoiler 17 through the rotating shaft, the activity of the column No. 18 on the spoiler 17 is increased. When the column No. 18 rotates inside the solution, the stability of the spoiler 17 driven by the column No. 18 is reduced, thereby increasing the swing amplitude of the spoiler 17. Moreover, by making the outer ring of the column No. 18 uneven, when the solution impacts the column No. 18, the column No. 1 is unevenly impacted by the solution, thereby further reducing the stability of the column No. 18, thereby improving the swing efficiency of the spoiler 17, thereby improving the mixing uniformity of the solution.

[0059] The specific workflow is as follows:

[0060] The solution is placed into the cylinder 1 through the feed port at the upper end of the cylinder 1. After placement, the motor at the bottom of the cylinder 1 is started. The motor drives the main shaft 3 to rotate. When the main shaft 3 rotates, the spiral blade 2 at the bottom is driven to rotate together. The spiral blade 2, with its inverted cone structure, transports the material at the bottom of the cylinder 1 upward along the inverted cone wall of the cylinder 1 to the middle of the cylinder 1, allowing the bottom solution to fully participate in mixing.

[0061] At the same time, the main shaft 3 drives the three slave shafts 4 connected to it to rotate. Since the slave shafts 4 are elastic, the three slave shafts 4 are opened outward under the action of centrifugal force. After the slave shafts 4 are opened, the length of the stirring rod 5 on the top layer is sufficient to push the rotating plate 14 to rotate. The rotating plate 14 slides in the slide groove 131 on the inner wall of the cylinder 1 through the annular block 13, and then rotates on the inner wall of the cylinder 1. When the rotating plate 14 rotates, the arc-shaped guide surface 141 on one side thereof guides the internal mixed solution toward the middle. The solution guided to the middle of the cylinder 1 through the arc-shaped guide surface 141 collides with the stirring rod 5, thereby promoting the mixing of the solutions.

[0062] When the stirring rod 5 in the middle layer stirs the material in the middle, it will intermittently contact the rotating plate 14 and produce vibration. This vibration helps to further break up the agglomerated particles in the solution and improve the uniformity of solution mixing. The stirring rod 5 in the lower layer cooperates with the spiral blade 2 to stir the solution near the bottom of the cylinder 1 to ensure that the bottom solution is fully involved in the mixing.

[0063] When the internal mixed solution rotates, the flow of the mixed solution will push one side of the rotating plate 14, and the force exerted on the rotating plate 14 is transmitted to the annular block 13, causing the annular block 13 to slide in the slide groove 131 on the inner wall of the cylinder 1, thereby causing the rotating plate 14 to rotate on the inner wall of the cylinder 1, and when the rotating plate 14 rotates, the arc-shaped guide surface 141 on one side of the rotating plate 14 guides the internal mixed solution toward the middle, and the solution guided to the middle of the cylinder 1 by the arc-shaped guide surface 141 collides with the stirring rod 5 again, further causing the stirring rod 5 to mix the solution on the inner wall of the cylinder 1, and at the same time, the arc-shaped guide surface 141 on one side of the rotating plate 14 scrapes the inner wall of the cylinder 1, thereby avoiding the problem of the inner wall of the cylinder 1 sticking to the wall.

[0064] Since the angle between the side surface corresponding to the arc-shaped guide surface 141 on the rotating plate 14 and the cylinder 1 is an acute angle, when the motor drives the main shaft 3 to rotate, and then drives the stirring rod 5 to stir the solution, the mixed liquid impacts the side surface corresponding to the arc-shaped guide surface 141 on the rotating plate 14. At this time, because the angle is an acute angle, the resistance encountered by the solution increases, and the power generated by the rotating plate 14 increases, thereby increasing the effect of the rotating plate 14 when scraping the inside of the cylinder 1, further avoiding the wall adhesion phenomenon.

[0065] When the stirring rod 5 is rotating, when it contacts the rotating plate 14, it will enter the No. 1 groove 15 opened on the side of the rotating plate 14 corresponding to the arc-shaped guide surface 141. The gasket arranged in the No. 1 groove 15 cushions the stirring rod 5 to prevent the stirring rod 5 from colliding with the rotating plate 14, thereby improving the service life of the rotating plate 14 and the stirring rod 5. Moreover, the blades 16 evenly arranged on the arc-shaped guide surface 141 of the rotating plate 14 can break the part of the scraped solution that adheres to the wall when the arc-shaped guide surface 141 scrapes the inner wall of the cylinder 1, thereby increasing the mixing degree of the solution.

[0066] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
