Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a cross-shaped bottom frame type agitator. Background Technology

[0002] In industrial production fields such as chemical, food, and building materials, agitators are core equipment for achieving processes such as material mixing, reaction, and dissolution, and their performance directly affects product quality and production efficiency. Currently, although traditional agitators are widely used in various production scenarios due to their relatively simple structural design, they have gradually revealed many technical limitations in actual operation, making it difficult to meet the requirements of high-precision and high-efficiency mixing.

[0003] Traditional mixers generally suffer from insufficient bottom mixing. In most traditional equipment, the mixing blades are concentrated in the upper and middle areas, or the blade angle and installation position are fixed, resulting in insufficient coverage of the material on the inner wall of the bottom of the mixing tank. In addition, some mixers use a single shaft drive with a fixed mixing path, which makes the material at the bottom prone to sedimentation due to insufficient mixing force. This sedimentation phenomenon is more obvious when dealing with high viscosity or granular materials, directly affecting the overall mixing uniformity.

[0004] Meanwhile, the easy stratification of materials is another prominent problem of traditional mixers. When dealing with mixtures with large differences in specific gravity, the mixing method of traditional mixers is relatively simple, mainly horizontal stirring, which makes it difficult to form an upward and downward convection flow of materials. In addition, there are dead corners in the mixing path, and heavier materials tend to sink while lighter materials tend to float, which ultimately leads to material stratification and fails to achieve the ideal mixing effect.

[0005] Therefore, this utility model proposes a cross-shaped bottom frame mixer to solve the above problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings mentioned in the background section by proposing a cross-shaped bottom frame stirrer.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cross-shaped bottom frame mixer, including a mixing tank, a cross-shaped frame, a drive motor, two mixing shafts, two mixing shafts, two mixing shafts, a stirring assembly, a turbulence assembly, a turbulence assembly, a turbulence assembly, and a control panel;

[0009] The top and bottom of the mixing tank are fixedly equipped with feed pipes and multiple support legs. A discharge pipe is fixedly installed on one side of the bottom of the mixing tank, and a discharge valve is provided on the discharge pipe. The drive motor is fixedly installed at the top center of the mixing tank. The control panel is fixedly installed on the outside of the mixing tank and electrically connected to the drive motor. The output shaft of the drive motor extends into the mixing tank and is fixedly installed with a mounting sleeve. A cross-shaped frame is fixedly installed horizontally on the mounting sleeve. Six mounting seats are fixedly installed on the bottom side of the cross-shaped frame. The top ends of two mixing shafts one, two mixing shafts two, and two mixing shafts three are respectively fixedly installed on the corresponding mounting seats. The first turbulence component is located at the bottom end of the two mixing shafts one, two mixing shafts two, and two mixing shafts three. The tumbling component is located on the bottom side of the mounting sleeve. The second turbulence component is located on the side of the tumbling component away from the mounting sleeve. The third turbulence component is located on one mixing shaft one, one mixing shaft two, and one mixing shaft three.

[0010] Preferably, the first turbulence assembly includes six lower turbulence plates. The bottom ends of the two first stirring shafts, the two second stirring shafts, and the two third stirring shafts are all fixedly installed with lower turbulence plates, and the six lower turbulence plates are all arranged in an inclined manner.

[0011] Preferably, the six lower spoilers are installed at different angles.

[0012] Preferably, the mixing assembly includes a fixed shaft and spiral blades. The fixed shaft is fixedly installed at the center of the bottom of the cross-shaped frame, and the spiral blades are fixedly installed on the fixed shaft.

[0013] Preferably, the second turbulence component includes a connecting shaft, multiple upper deflector plates, and two lower deflector plates. The bottom end of the fixed shaft is axially fixedly connected to the connecting shaft, and multiple upper deflector plates and two lower deflector plates are fixedly installed on the connecting shaft. The multiple upper deflector plates and two lower deflector plates are all inclined, and the two lower deflector plates are symmetrically arranged based on the connecting shaft and close to the bottom inner wall of the mixing tank.

[0014] Preferably, the turbulence assembly three includes three upper turbulence plates. One of the two stirring shafts, one of the two stirring shafts, and one of the two stirring shafts are fixedly installed with an upper turbulence plate. The three upper turbulence plates are installed at different tilt angles.

[0015] Preferably, a guide plate is fixedly installed on the cross-shaped frame at the end away from the mounting sleeve, and the guide plate is inclined toward the inner wall of the mixing tank.

[0016] Preferably, the top side of the cross-shaped frame is inclined.

[0017] Preferably, the fixed shaft, the cross-shaped frame, the first stirring shaft, the second stirring shaft, and the third stirring shaft are all hollow.

[0018] Preferably, a shock-absorbing pad is fixedly installed at the bottom end of the support leg.

[0019] The beneficial effects of this utility model are:

[0020] By installing six lower baffles at different angles at the bottom of different stirring shafts, a multi-directional thrust is generated on the material at the bottom inner wall of the mixing tank, effectively preventing material deposition and promoting its upward churning. At the same time, the spiral blades in the churning assembly can continuously push the material at the bottom center upward to the upper middle area, forming convection with the horizontal material flow. Furthermore, the upper and lower baffles in the second baffle assembly perform secondary churning on the material at the bottom center, forming a circulating flow path for the bottom material in conjunction with the spiral blades. In addition, the three upper baffles in the third baffle assembly perform multi-directional cutting and disturbance on the material in the upper middle area, breaking the horizontal flow inertia and avoiding stratification or vortex phenomena.

[0021] The guide plate moves materials close to the barrel wall toward the center, while the inclined design of the top side of the cross-shaped frame prevents material accumulation. The hollow structure of the stirring shaft, cross-shaped frame, and fixed shaft effectively reduces the overall weight and the load on the drive motor, while the shock-absorbing pads improve the stability of the equipment operation.

[0022] This invention constructs a three-dimensional, highly efficient mixing system by setting a cross-shaped frame as the core for bearing and transmitting the mixing power, and cooperating with a drive motor to drive two mixing shafts (one, two, and three) to rotate around the installation. Through the cooperation of these structures, the material in the mixing tank can be acted on from bottom to top and from center to edge in all directions, which significantly improves the uniformity of material mixing and mixing efficiency. It solves the problems of insufficient bottom mixing and easy material stratification in traditional mixers. It is suitable for the mixing needs of various materials and has strong practicality and economy. Attached Figure Description

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Reference Figure 1-8 A cross-shaped bottom frame mixer includes a mixing tank 1, a cross-shaped frame 2, a drive motor 22, two mixing shafts 3, two mixing shafts 5, two mixing shafts 6, and a control panel 10.

[0035] The top and bottom of the mixing tank 1 are fixedly installed with a feed pipe 12 and multiple support legs 11. The bottom side of the mixing tank 1 is fixedly installed with a discharge pipe 13, and a discharge valve 14 is provided on the discharge pipe 13. The drive motor 22 is fixedly installed at the top center of the mixing tank 1. The control panel 10 is fixedly installed on the outside of the mixing tank 1 and electrically connected to the drive motor 22. The output shaft of the drive motor 22 extends into the mixing tank 1 and is fixedly installed with a mounting sleeve 21. The cross-shaped frame 2 is fixedly installed horizontally on the mounting sleeve 21. Six mounting seats 201 are fixedly installed on the bottom side of the cross-shaped frame 2. The top ends of the two first stirring shafts 3, the two second stirring shafts 5 and the two third stirring shafts 6 are respectively fixedly installed on the corresponding mounting seats 201.

[0036] The bottom ends of the two stirring shafts 1 (3), the two stirring shafts 2 (5), and the two stirring shafts 3 (6) are all fixedly installed with lower baffles 8. The six lower baffles 8 are all set at an angle, which can effectively enhance the stirring effect of the material at the bottom inner wall of the mixing tank 1, prevent the material from settling at the bottom, and the six lower baffles 8 are installed at different angles. When they rotate with the cross-shaped frame 2, they can generate multi-directional thrust on the bottom material, causing the settled material to surge upward and mix fully with the upper material, improving the uniformity of the overall mixing and solving the problem of insufficient mixing at the bottom of traditional mixers.

[0037] A fixed shaft 4 is fixedly installed at the center of the bottom of the cross-shaped frame 2. A spiral blade 41 is fixedly installed on the fixed shaft 4, which can generate an upward pushing force on the material during the mixing process. The material at the center of the bottom inner wall of the mixing tank 1 is continuously transported upward to the upper middle area of ​​the mixing tank 1 and the horizontally moving material flow forms convection, further breaking the stratification of the material and promoting the rapid fusion of materials in different areas.

[0038] A connecting shaft 42 is axially fixed to the bottom end of the fixed shaft 4. Multiple upper deflector plates 43 and two lower deflector plates 44 are fixedly installed on the connecting shaft 42. The multiple upper deflector plates 43 and two lower deflector plates 44 are all inclined. The two lower deflector plates 44 are symmetrically arranged based on the connecting shaft 42 and close to the bottom inner wall of the mixing tank 1. They can perform secondary agitation on the material in the central area at the bottom of the mixing tank 1. Combined with the upward pushing action of the spiral blades 41, a circulating flow path for the bottom material is formed.

[0039] Upper baffles 7 are fixedly installed on one of the two stirring shafts 1 3, one of the two stirring shafts 2 5, and one of the two stirring shafts 3 6. The three upper baffles 7 are installed at different tilt angles, which can form multi-directional cutting and disturbance of the material in the upper area of ​​the mixing tank 1 when rotating with the cross-shaped frame 2. This breaks the flow inertia of the material in the horizontal direction, promotes the interweaving and mixing of materials at different heights and positions, avoids material stratification or vortex phenomena caused by a single stirring direction, and further improves the overall convection effect of the material in the mixing tank 1. Together with multiple lower baffles 8, spiral blades 41, upper baffles 43 and lower baffles 44, they form a three-dimensional stirring system from bottom to top and from center to edge, which significantly improves the uniformity of material mixing and stirring efficiency.

[0040] In order to move the material close to the inner wall of the mixing tank 1 towards the axis of the mixing tank 1 when the drive motor 22 controls the cross-shaped frame 2 to rotate, a guide plate 9 is fixedly installed on the cross-shaped frame 2 at the end away from the mounting sleeve 21, and the guide plate 9 is inclined towards the inner wall of the mixing tank 1.

[0041] In this embodiment, in order to avoid the accumulation of materials on the top side of the cross-shaped frame 2 when adding materials into the mixing tank 1 through the feed pipe 12, the top side of the cross-shaped frame 2 is set in an inclined shape.

[0042] In this embodiment, in order to effectively reduce the weight of the overall structure and reduce the load on the drive motor 22, thereby reducing energy consumption and extending the service life of the equipment, while also saving material costs, the economy and practicality of the stirrer are optimized while ensuring structural strength. Installation positions are also reserved for possible future functional expansion, such as built-in temperature sensors or material concentration detection elements, to improve the multifunctionality and applicability of the equipment. The fixed shaft 4, cross-shaped frame 2, stirring shaft one 3, stirring shaft two 5 and stirring shaft three 6 are all hollow.

[0043] In this embodiment, in order to effectively buffer the vibration generated by the mixer during operation, reduce the hard impact between the equipment and the ground, reduce the impact of vibration transmission on the working environment and surrounding equipment, and at the same time avoid the vibration causing displacement or loosening between the support leg 11 and the ground, improve the stability and safety of the mixer in working condition, and extend the service life of the support structure, a shock-absorbing pad is fixedly installed at the bottom of the support leg 11.

[0044] It is worth noting that the content protected by this application does not involve improvements to software, circuits, and methods. Therefore, the circuits, electronic components, and module mechanisms involved all adopt existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0045] Among them, the two stirring shafts 3 and 5 are located in the same plane as the mounting sleeve 21, and the two stirring shafts 6 are located in the same plane as the mounting sleeve 21. The distance between the axes of the two stirring shafts 3 and the mounting sleeve 21 is different, the distance between the axes of the two stirring shafts 5 and the mounting sleeve 21 is different, and the distance between the axes of the two stirring shafts 6 and the mounting sleeve 21 is also different. The specific distance values ​​can be determined and implemented by the technicians according to the actual situation. The purpose is to enable different stirring shafts to stir different areas in the mixing tank 1 when the cross-shaped frame 2 rotates under the drive of the drive motor 22, thereby further improving the stirring effect.

[0046] Working Principle: In operation, first connect the power supply and add the material to be mixed into the mixing tank 1 through the feed pipe 12. Then, start the drive motor 22 via the control panel 10. The output shaft of the drive motor 22 drives the mounting sleeve 21 and the cross-shaped frame 2 to rotate synchronously. The cross-shaped frame 2 then drives the two stirring shafts 3, 5, and 6 to move in a circular motion around the axis of the mixing tank 1. During this process, the six lower baffles 8 rotate with their corresponding stirring shafts. Due to their different angles of inclination, they can generate multi-directional thrust on the material at the bottom inner wall of the mixing tank 1, effectively agitating the bottom material and causing the sediment to rise, preventing material from settling at the bottom. Simultaneously, the spiral blades 41 on the fixed shaft 4 rotate with the cross-shaped frame 2, generating an upward pushing force, continuously conveying the material from the bottom center area to the upper middle area. The mixing zone forms a convection with the horizontally moving material flow, breaking the material stratification. In addition, multiple upper baffles 43 and two lower baffles 44 on the connecting shaft 42 rotate synchronously, which can perform secondary agitation on the material in the bottom center area. Together with the spiral blades 41, they form a circulating flow path for the bottom material, further enhancing the mixing effect of the bottom material. Meanwhile, the three upper baffles 7 rotate with the corresponding mixing shaft in the upper middle area, and cut and disturb the material in multiple directions through different tilt angles, breaking the horizontal flow inertia of the material, and promoting the interweaving and mixing of materials at different heights and positions, avoiding stratification or vortex phenomena. When the guide plate 9 rotates in the cross-shaped frame 2, it can push the material close to the inner wall of the mixing tank 1 towards the center, preventing the material from adhering and accumulating on the tank wall. The inclined design of the top side of the cross-shaped frame 2 avoids the accumulation of material on top when it is added.

[0047] The cross-shaped bottom frame stirrer provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
