Description

Technical Field

[0001] This utility model relates to the field of concrete product manufacturing machinery technology, specifically a mixing reactor for concrete block production. Background Technology

[0002] In the construction industry, concrete blocks are an important material for building construction due to their good strength and durability. The mixing reactor is the core equipment for concrete block production, which directly affects the uniformity of concrete and the quality of finished blocks.

[0003] Currently, commercially available concrete block production mixing reactors suffer from poor mixing performance. Some reactors have poorly designed impellers, limiting their ability to grip and agitate materials. This results in incomplete mixing of raw materials such as cement, sand, water, and additives, leading to localized segregation and clumping. Furthermore, some reactors lack effective mixing path planning, resulting in a single flow trajectory for materials within the reactor, hindering efficient convection and creating dead zones that negatively impact mixing efficiency. Additionally, traditional mixing reactors struggle to adjust mixing intensity and speed according to different proportions and properties of materials, failing to meet diverse production needs. This leads to unstable strength and density properties in concrete blocks, increasing scrap rates and hindering the quality and efficiency of concrete block production. Utility Model Content

[0004] The purpose of this invention is to provide a mixing reactor for the production of concrete blocks, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a mixing reactor for concrete block production, including a reactor, a cover, a servo motor, a mixing assembly, and a support assembly. The cover is adapted to cover the top opening of the reactor, and the servo motor is mounted on the cover to drive the mixing assembly. The mixing assembly includes a connecting rod, a spiral blade, a mixing blade, a mounting rod, a mixing rod, and a spiral mixing blade. One end of the connecting rod is connected to the output shaft of the servo motor, and the other end extends into the reactor. The spiral blade, mixing blade, mounting rod, mixing rod, and spiral mixing blade are sequentially or in combination mounted on the connecting rod for stirring the materials inside the reactor. The support assembly includes legs for supporting the reactor.

[0006] Furthermore, the bottom of the reactor is provided with a discharge pipe for discharging the stirred material, and the discharge pipe is equipped with a valve for controlling its opening and closing.

[0007] Furthermore, the cover is provided with a feed pipe for feeding raw materials into the reactor, and a sealing cover can be installed at the feed pipe.

[0008] Furthermore, there are multiple spiral blades, stirring blades, and spiral stirring blades, which are distributed at intervals along the axial direction of the connecting rod, and the stirring trajectories of adjacent components are intersected.

[0009] Furthermore, the operating speed of the mixing component is adjustable. By controlling the rotation speed of the servo motor, it can adapt to the mixing requirements of materials with different proportions and characteristics, so that the mixing force and speed are adapted to the materials, thus ensuring the quality of concrete mixing.

[0010] Furthermore, the cover and the reactor are detachably connected via mounting blocks and a suitable connecting structure, facilitating cleaning, maintenance, and repair of the reactor interior and stirring components.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, after the servo motor is started, its output shaft drives the connecting rod to rotate, which in turn drives the spiral blades, stirring blades, and other components to rotate synchronously. The spiral blades lift the material upward to form a vertical circulating flow, while the stirring blades radially shear and disperse the material. The mounting rod and stirring rod expand the mixing range and intensity, and the spiral stirring blades promote the spiral flow of the material. Multiple mixing components work together to form a three-dimensional cross mixing path, gripping and turning the material to prevent segregation and clumping, improving the uniformity of the concrete mixture and enhancing the stability of the block performance. Furthermore, the components are spaced apart along the axial direction of the connecting rod, and the mixing trajectories are staggered, eliminating mixing dead zones and effectively improving mixing efficiency.

[0013] 2. In this utility model, multiple components, including spiral blades, stirring blades, and spiral stirring blades, are distributed at intervals along the connecting rod axis. This allows them to cover materials at different heights within the reactor, promoting vertical circulation and avoiding uneven mixing caused by height differences. The stirring trajectories of adjacent components are staggered, breaking the single flow trajectory of the materials, forming efficient convection, eliminating stirring dead zones, strengthening the gripping, turning, and dispersing of raw materials such as cement, reducing segregation and agglomeration, achieving three-dimensional full mixing of materials, improving the uniformity of concrete mixtures, and ensuring the stability of concrete block strength, density, and other properties.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution:

[0021] See Figures 1-4 As shown, a mixing reactor for producing concrete blocks includes a reactor 1, a cover 2, a servo motor 3, a mixing assembly, and a support assembly. The cover 2 is fitted to the top opening of the reactor 1. The servo motor 3 is mounted on the cover 2 to drive the mixing assembly. The mixing assembly includes a connecting rod 4, a spiral blade 5, a stirring blade 6, a mounting rod 7, a stirring rod 8, and a spiral stirring blade 9. One end of the connecting rod 4 is connected to the output shaft of the servo motor 3, and the other end extends into the reactor 1. The spiral blade 5, the stirring blade 6, the mounting rod 7, the stirring rod 8, and the spiral stirring blade 9 are sequentially or in combination mounted on the connecting rod 4 to stir the materials inside the reactor 1. The support assembly includes legs 12 for supporting the reactor 1.

[0022] When the servo motor 3 is started, its output shaft drives the connecting rod 4 to rotate, thereby driving the spiral blade 5, stirring blade 6, mounting rod 7, stirring rod 8, and spiral stirring blade 9 mounted on the connecting rod 4 to rotate synchronously. The rotation of the spiral blade 5 generates axial thrust, lifting the material at the bottom of the reactor 1 upwards, forming a vertical circulation flow of the material. The stirring blade 6 performs radial shearing and dispersion of the material during rotation, breaking up material agglomeration. The mounting rod 7 and stirring rod 8 further increase the range and intensity of the stirring, ensuring that the material is fully agitated in all directions. The spiral stirring blade 9, while stirring, promotes the formation of a spiral flow trajectory, enhancing the mixing effect between materials. Through this multi-dimensional and multi-layered stirring method, the problems of a single material flow trajectory and dead zones in traditional stirred reactor 1 are effectively solved, allowing raw materials such as cement, sand, water, and additives to be fully mixed.

[0023] Multiple mixing components, such as spiral blade 5, mixing blade 6, and spiral mixing blade 9, work together to form a three-dimensional cross mixing path, which can effectively grab and turn the material, avoid local segregation and clumping, significantly improve the uniformity of the concrete mixture, and thus improve the strength, density and other performance stability of the concrete blocks.

[0024] Multiple stirring components are distributed at intervals along the connecting rod 4 and their stirring trajectories are interwoven, ensuring that the materials in each area of ​​the reactor 1 can be fully stirred, eliminating the stirring dead zones that exist in traditional stirred reactor 1, and improving stirring efficiency.

[0025] See Figure 3 The bottom of the reactor 1 is equipped with a discharge pipe 10 for discharging the stirred material. The discharge pipe 10 is equipped with a valve to control its opening and closing.

[0026] The bottom of the reactor 1 is equipped with a discharge pipe 10, which allows for the rapid discharge of materials after mixing is completed by opening the valve, eliminating the need for additional pouring operations, simplifying the unloading process, and improving production efficiency. The valve, which controls the opening and closing, can precisely control the timing and flow of discharge, preventing material leakage before mixing is complete and also preventing material spillage and waste due to excessively rapid unloading. At the same time, when it is necessary to continuously mix and adjust the material in the reactor 1, closing the valve can keep the material in the reactor, ensuring the mixing effect and material stability, making the entire production process more controllable, and facilitating the orderly production of concrete blocks.

[0027] See Figure 2 The cover 2 is provided with a feed pipe 11, which is used to feed raw materials into the reactor 1. A sealing cover can be installed at the feed pipe 11.

[0028] The cover 2 is equipped with a feed pipe 11, which facilitates the precise addition of raw materials such as cement, sand, water, and additives into the reactor 1 without the need to frequently open the cover 2, reducing the risk of material splashing and impurities entering, and ensuring the purity of the materials. The sealing cover can promptly close the feed pipe 11 after the raw materials are added, preventing materials from overflowing from the feed pipe 11 during the mixing process. It also prevents dust and debris from falling into the reactor 1 and affecting the mixing quality of the materials, while maintaining a stable mixing environment inside the reactor 1, thus helping to improve the efficiency and quality of concrete block production.

[0029] See Figure 1 There are multiple spiral blades 5, stirring blades 6, and spiral stirring blades 9, which are distributed at intervals along the axial direction of the connecting rod 4, and the stirring trajectories of adjacent components are intersected.

[0030] The spiral blades 5, stirring blades 6, and spiral stirring blades 9 are arranged in multiples and spaced apart along the connecting rod 4. They can cover materials at different heights within the reactor 1, enabling the materials to form a continuous vertical circulation flow and avoiding uneven mixing caused by height differences. The stirring trajectories of adjacent components intersect each other, breaking the original single flow trajectory of the materials and forming a complex and efficient convection motion. This eliminates stirring dead zones, effectively improves the ability to grasp, turn over, and disperse raw materials such as cement, sand, water, and additives, reduces local segregation and clumping, and ensures that the materials are fully mixed in three-dimensional space. This significantly improves the uniformity of the concrete mixture, thereby ensuring the stability of the strength, density, and other properties of the concrete blocks.

[0031] See Figure 1 The operating speed of the mixing component is adjustable. By controlling the speed of the servo motor 3, it can adapt to the mixing requirements of materials with different proportions and characteristics, so that the mixing force and speed are matched with the materials, ensuring the quality of concrete mixing.

[0032] By controlling the rotation speed of the servo motor 3 to adjust the operating speed of the mixing component, the mixing scheme can be flexibly adjusted for materials with different proportions and characteristics. For materials with poor flowability, the rotation speed can be increased to enhance the mixing force and promote thorough mixing. For materials that are prone to segregation, the rotation speed can be reduced to avoid over-mixing and damaging the structure. It can adapt to the mixing needs of aggregates with different particle sizes and different additive combinations, so that raw materials such as cement, sand, water and additives are uniformly mixed under the optimal mixing force and speed, reducing segregation and agglomeration, improving the uniformity and stability of concrete mixtures, thereby effectively ensuring the quality indicators such as strength and density of concrete blocks. At the same time, it avoids energy waste and low production efficiency caused by improper mixing parameters, and improves the overall efficiency of concrete block production.

[0033] See Figure 4 The cover 2 and the reactor 1 are detachably connected by the mounting block 13 and the matching connection structure, which facilitates cleaning, maintenance and repair of the inside of the reactor 1 and the stirring components.

[0034] The cover 2 and the reactor 1 are detachably connected via mounting block 13 and an adapter connection structure. The cover 2 can be quickly removed after the equipment is used, allowing staff to easily access the reactor 1 to clean the stirring components and prevent residual materials from solidifying and affecting the quality of the next stirring operation. During maintenance, the cover 2 can be directly removed to visually inspect the operating status of components such as the servo motor 3 and connecting rod 4, enabling timely detection and handling of faults and reducing the difficulty of equipment maintenance. During maintenance, worn stirring blades 6, spiral stirring blades 9, and other components can be replaced to ensure the stable performance of the stirring components and extend the service life of the equipment. At the same time, the detachable structure makes the maintenance process more convenient and efficient, reduces downtime for maintenance, and improves the continuity and reliability of concrete block production.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
