Especially for systems with high-viscosity additives or containing fiber or particulate reinforcing phases, agglomeration is prone to occur, resulting in poor mixing uniformity.

A fixing frame 47 is fixedly connected to the outer wall of the outer ring body 42 and the outer wall of the fixing frame 47 is fixedly connected to the outer wall of the mixing cylinder 41. When the outer ring body 42 rotates, the hammering balls 44 move in a circular motion with the ring body and collide with the wear-resistant balls 46 fixed to the cylinder wall at high frequency. This impact action achieves the crushing of material particles through the momentum transfer principle. The linear velocity of the hammering balls 44 is converted into impact kinetic energy, which impacts and breaks up agglomerated particles.

[0021] The cleaning assembly 5 includes a main inlet pipe 53, with connecting pipes 52 symmetrically fixed to the outer wall of the main inlet pipe 53.

When the cleaning fluid enters the rotating shell 66 through the liquid inlet pipe 65, the guide vane 63 guides the fluid to be sprayed at an angle along the inclined spray groove 62. According to the principle of conservation of momentum, the reaction torque generated by the sprayed fluid drives the rotating shell 66 to rotate, forming a dynamic cleaning mode of rotating and spraying at the same time.

[0023] The discharge assembly 2 includes a discharge shell 21. A control shell 24 is fixedly connected to the top of the discharge shell 21. A pipe body 23 is fixedly connected to the top of the control shell 24. A blocking plate 27 is symmetrically slidably connected to the inner wall of the control shell 24.

The outer wall of the connecting frame 26 is fixedly connected to the outer wall of the top spring 25. The outer wall of the connecting frame 26 is fixedly connected to the outer wall of the blocking plate 27. The end of the top spring 25 away from the connecting frame 26 is fixedly connected to the outer wall of the control shell 24. When unloading is required, an external force (such as cylinder thrust or electric actuator) compresses the top spring 25 through the connecting frame 26, causing the blocking plate 27 to slide to both sides, opening the discharge channel. The material is discharged through the discharge shell 21. This mechanical linkage design makes the opening and closing of the discharge port quick and reliable, avoiding the jamming phenomenon that may occur in traditional valve structures. The outer wall of the discharge shell 21 is fixedly connected to the inner wall of the support leg 1. The top of the pipe body 23 is fixedly connected to the bottom of the mixing cylinder 41.

[0024] A method for using a uniformly mixing cement admixture mixing reactor, comprising the following steps: Step 1: Material is fed into the mixing drum 41 through the top feed inlet. The stepper motor 45 is started to drive the outer ring body 42 to rotate. A composite flow field is formed through the double ring gap structure. The material is crushed and mixed by the impact and shearing action of the hammer ball 44 and the wear-resistant ball 46 to obtain a preliminary mixture. Step 2: The connecting frame 26 is driven by external force to compress the top spring 25, opening the discharge channel of the blocking plate 27. The material is discharged through the discharge shell 21. The flow rate is controlled by adjusting the stroke of the blocking plate 27 to obtain the finished material. After the unloading is completed, the discharge channel is reset and sealed by the top spring 25. Step 3: Cleaning liquid is connected through the liquid inlet manifold 53 and diverted through the top spray shell 51 and the bottom spray shell 54. The inner ring body 43 is started to drive the spraying assembly 6 to rotate. The guide vane 63 and the inclined spray channel 62 form a spiral spray. The cleaning waste liquid is discharged through the discharge assembly 2, completing the cleaning of the mixing drum 41.

[0025] The cement admixture mixing reactor provided by this invention addresses the technical bottlenecks of traditional mixing equipment in terms of mixing uniformity, ease of cleaning, and controllable discharge. Through mechanical structural innovation and multi-component collaborative design, a multi-functional system integrating mixing, cleaning, and discharge is constructed. The main body of the equipment consists of support legs 1, discharge components 2, and integrated components 3 (including mixing components 4 and cleaning components 5). Through the organic combination of mechanical transmission, fluid mechanics principles, and material properties, the entire process of cement admixture production is optimized. The following will elaborate on the working mechanism of the core components, the collaborative process, and the technological innovation.

[0026] The mixing component 4 is the core unit for achieving uniform material dispersion. Its design is based on the principles of mechanical transmission and fluid dynamics. Through the combined action of the rotation of the double-ring structure and the impact of the elements, a multi-dimensional mixing field is formed.

[0027] The core of the mixing component 4 is a double-ring structure consisting of an outer ring 42 and an inner ring 43. A stepper motor 45 drives the outer ring 42 to rotate, and a fixing frame 47 restricts the position of the outer ring 42 at the other end. The inner ring 43 inside the outer ring 42 remains stationary, forming a reverse differential motion. This design breaks the laminar flow limitation of traditional single-shaft stirring and induces a key flow field effect in the mixing cylinder 41. That is, the gap between the outer ring 42 and the inner wall of the mixing cylinder 41 forms a high-speed shearing zone, which generates strong shear force on the material and effectively disperses particle agglomerates. The double-ring operation induces vortex disturbance in the central region of the mixing cylinder 41, forming a chaotic mixing domain, which accelerates the diffusion and convection of different components.

[0028] This composite flow field causes the material to undergo both radial shear dispersion and axial circulation within the mixing cylinder 41, improving mixing efficiency and uniformity. Compared to traditional single-shaft mixing equipment, the double-ring reverse structure can achieve uniform mixing of materials in a shorter time, reducing mixing energy consumption and time costs. The hammer balls 44 evenly distributed on the outer side of the outer ring 42 and the wear-resistant balls 46 on the inner wall of the mixing cylinder 41 form an impact system. When the outer ring 42 rotates, the hammer balls 44 move in a circular motion with the ring and collide with the wear-resistant balls 46 fixed on the cylinder wall at high frequency. This impact action breaks up the material particles through the principle of momentum transfer. The linear velocity of the hammer balls 44 is converted into impact kinetic energy, which impacts and breaks up agglomerated particles. The hammer balls 44 and wear-resistant balls 46 are made of high-hardness materials (such as hard alloy and ceramic), which causes local stress concentration at the impact point, effectively destroying the bonding force between particles. The staggered arrangement of the hammer balls 44 along the circumferential direction ensures that the material is impacted at different axial positions, avoiding mixing blind spots.

[0029] Through the synergistic effect of impact and shear, the mixing component 4 can effectively disperse the agglomerated particles in the cement admixture. Compared with the use of chemical dispersants, this physical crushing method not only reduces production costs but also avoids the problem of cement performance fluctuations that may be caused by the introduction of additives.

[0030] In the initial stage of mixing, the material enters the mixing cylinder 41 through the top feed port. After the stepper motor 45 is started, the double-ring structure quickly establishes a reverse flow field. The impact of the hammer ball 44 and the wear-resistant ball 46 first breaks up the large particle agglomerates. At the same time, the shear flow in the gap between the double rings further disperses the broken particles. As the rotation continues, the axial propulsion flow drives the material to circulate along the axis of the mixing cylinder 41. The eddy current coupling effect ensures the uniform distribution of the radial layer.

[0031] During this process, the material undergoes a triple action of "impact crushing → shear dispersion → eddy mixing". For high-viscosity admixture systems, the strong shear force generated by the double-ring structure can reduce the apparent viscosity of the material and improve its fluidity. For composite admixtures containing fiber or particulate reinforcing phases, the impact system can prevent fiber agglomeration and ensure the uniform distribution of the reinforcing phase in the matrix. This dynamic synergistic mechanism makes the mixing component 4 suitable for the production of various types of cement admixtures and has a wide range of process adaptability.

[0032] The cleaning component 5, through a combination of multi-directional spraying and rotary jetting, solves the problems of incomplete cleaning and excessive manual intervention required by traditional mixing equipment. Its working principle is based on fluid jet dynamics and mechanical kinematics. After the cleaning fluid (such as water or alkaline cleaning agent) is connected to the main inlet pipe 53, it is diverted to the top spray shell 51 and the bottom spray shell 54 through the connecting pipe 52. The top spray shell 51 uses a wide-angle nozzle with the spray direction perpendicular to the top surface of the tank to form a fan-shaped coverage area, which quickly washes away the residual adhering additives on the top. The bottom spray shell 54 performs directional flushing on the bottom of the tank and the vicinity of the discharge port to prevent the deposited material from solidifying.

[0033] The dual-spray system forms a three-dimensional rinsing network that works in tandem with the top, side walls, and bottom of the tank to cover the main adhesion areas. During the cleaning process, the top spray first removes large areas of loose deposits, while the bottom spray intensifies the rinsing of areas prone to deposits. The combination of the two reduces cleaning dead spots and improves cleaning efficiency.

[0034] The spraying assembly 6 is fixedly connected to the inner ring body 43 by the support column 61. The guide vane 63 on the inner wall of the core component rotating shell 66 adopts a spiral design, and a diversion block 64 is provided at the liquid inlet pipe 65, so that the cleaning fluid through the connecting branch pipe 56 is diverted and impacts the guide vane 63. When the cleaning fluid enters the rotating shell 66 through the liquid inlet pipe 65, the guide vane 63 guides the fluid to spray at an angle along the inclined spray groove 62. According to the principle of conservation of momentum, the reaction torque generated by the sprayed fluid drives the rotating shell 66 to rotate, forming a dynamic cleaning mode of rotating and spraying at the same time.

[0035] This design allows the cleaning fluid to form a spiral scouring trajectory on the inner wall of the mixing cylinder 41, covering the entire circumferential and axial areas. It effectively cleans the junction between the cylinder wall and the bottom, which is difficult for traditional mixing equipment to reach. The presence of the rotating spray component 6 transforms the local coverage of static spraying into dynamic full-surface coverage, significantly improving the cleaning effect.

[0036] During the cleaning process, the cleaning component 5 and the mixing component 4 work together. The rotation of the inner ring 43 causes the residual material to be accelerated to leave the tank wall under the dual action of fluid flushing and mechanical stirring. The waste liquid after cleaning is discharged through the discharge component 2, completing the entire cleaning process. This collaborative cleaning mechanism makes equipment maintenance more convenient, reduces manual intervention, and lowers labor intensity.

[0037] The discharge assembly 2 achieves control and reliable sealing of the unloading process through an elastic blocking structure and mechanical linkage mechanism. Its design integrates the principles of elasticity and mechanical transmission theory.

[0038] The core of the discharge assembly 2 is the sealing fit between the blocking plate 27 inside the control housing 24 and the tube 23. In the initial state, the preload provided by the top spring 25 makes the blocking plate 27 fit tightly against the inner wall of the tube 23, forming a reliable seal. When unloading is required, external force (such as cylinder thrust or electric actuator) compresses the top spring 25 through the connecting frame 26, causing the blocking plate 27 to slide to both sides, opening the discharge channel, and the Shudie material is discharged through the discharge housing 21. This mechanical linkage design makes the opening and closing of the discharge port quick and reliable, avoiding the jamming phenomenon that may occur in traditional valve structures.

[0039] During the unloading process, the sliding stroke of the blocking plate 27 can be controlled by adjusting the magnitude of the external force, thereby controlling the discharge flow rate. For materials with different flow rates, the opening of the discharge port can be adjusted according to the actual situation to ensure a smooth and stable unloading process. After the unloading is completed, the external force is removed, and the elastic reset action of the top spring 25 causes the blocking plate 27 to quickly return to its initial position and restore the sealing state.

[0040] The bottom spray system (bottom spray shell 54 and spray shell 55) of the cleaning component 5 can directly flush the discharge port to prevent residual materials from solidifying and clogging the channel. This combination of anti-residue design and self-cleaning function ensures the long-term reliable operation of the discharge component 2 and reduces equipment failures caused by blockage.

[0041] After the material enters the mixing cylinder 41 through the top feed port, the stepper motor 45 is started to drive the outer ring body 42 to rotate, and the mixing component 4 starts to work. Through the synergistic effect of double ring shearing and impact grinding, the material reaches a uniform mixing state in a short time. During this process, the discharge component 2 remains sealed to prevent material leakage.

[0042] Once mixing is complete, push the blocking plate 27 to open the discharge port. The uniformly mixed material is discharged through the pipe 23 under gravity or external pressure. During the unloading process, the opening of the discharge port can be adjusted as needed to control the unloading speed.

[0043] After unloading, switch to cleaning mode. The inlet manifold 53 of the cleaning component 5 is connected to the cleaning fluid. The top spray shell 51, bottom spray shell 54 and rotating spray component 6 work simultaneously. The inner ring 43 of the mixing component 4 drives the spray component 6 to rotate, so as to achieve comprehensive cleaning of the inner wall of the mixing cylinder 41. The cleaning waste liquid is discharged through the discharge component 2, completing the cleaning process.
