Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixing, and particularly to a device for preventing precipitation of concrete admixtures. Background Art

[0002] Currently, in the process of concrete production, the use of admixtures is crucial for improving the performance of concrete. However, many admixtures are prone to precipitation during storage and transportation, seriously affecting their use effect and the quality of concrete. Traditional admixture storage tanks are usually only equipped with simple stirring devices, and the stirring effect is not good, unable to effectively prevent the precipitation of admixtures.

[0003] To solve the above problems, a Chinese patent with the application number 202020772927.8 discloses a mixer for anti-precipitation concrete admixtures. When in use, when the stirring blade passes through the hemispherical block, the hemispherical block is lifted, and then the piston plate is driven to move upward by the hemispherical block, so that the material discharge hole on the piston plate is separated from the plug block. Then, the admixture in the tank enters the mixing pool through the material discharge hole on the piston plate, thereby realizing the uniform feeding of the admixture. However, before using the above technical solution, the user needs to first put the admixture into the admixture addition tank respectively, and then add it evenly. This method increases the operation steps, thus affecting the mixing efficiency of the admixture. And although it can mix the admixture in the mixing pool, it cannot process the admixture remaining on the inner wall of the mixing pool, resulting in certain limitations of its mixing mechanism.

[0004] The existing concrete mixing devices mainly focus on the mixing function of concrete in design, and insufficient consideration is given to the anti-precipitation and precise addition of admixtures. Although some mixing devices have simple mixing mechanisms, they cannot effectively prevent the precipitation of admixtures, resulting in the admixture not being fully and evenly dispersed in the concrete during the mixing process. At the same time, these devices lack automated design in the extraction and addition links of the admixture, still relying on manual operation, unable to meet the requirements of modern concrete production for high efficiency and precision. In addition, there are also certain problems with the structural stability and reliability of the existing mixing devices, and it is easy to have situations such as component loosening and wear during long-term operation, affecting the normal use of the device.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a device for preventing precipitation of concrete admixtures.

[0032] Embodiment 1: Please refer to Figures 1-8 , a device for preventing precipitation of concrete admixtures, including a mixing tank 2, inside which a mixing mechanism 5 is provided for mixing the concrete inside the mixing tank 2;

[0033] At the top of the mixing tank 2, an extraction assembly is provided, and the extraction mechanism includes a reciprocating mechanism 6 and a material extraction mechanism 7. The material extraction mechanism 7 includes an injection pipe 75, an admixture tank 78, and a transfer tank 710. When the reciprocating mechanism 6 operates, it drives the injection pipe 75 to extract the admixture inside the admixture tank 78 into the transfer tank 710.

[0034] On the outside of the transfer tank 710, a feeding mechanism 8 is provided. The feeding mechanism 8 includes a baffle plate 88, and the baffle plate 88 is movably connected inside the transfer tank 710. When the reciprocating mechanism 6 operates, the baffle plate 88 opens to send out the admixture inside the transfer tank 710.

[0035] Embodiment 2: Refer to Figures 1-8 , which is different from the above Embodiment 1. A support plate 1 is fixedly connected to the outside of the mixing tank 2, and the support plates 1 are symmetrically distributed on the outside of the mixing tank 2. A controller 3 is provided on the outside of the support plate 1. On the outside of the top of the mixing tank 2, a feeding trough 4 is provided. The mixing mechanism 5 includes a motor 51, and the motor 51 is fixedly connected directly below the mixing tank 2. The output end of the motor 51 is fixedly connected to a rotating shaft 52, and evenly and symmetrically connected to the outside of the rotating shaft 52 are mixing blades 53. A discharge pipe 54 is provided on the outside of the mixing tank 2.

[0036] It should be noted that: The mixing mechanism 5 drives the rotating shaft 52 and the mixing blades 53 through the motor 51 to fully mix the concrete in the mixing tank 2, forming a strong turbulent flow, so that the admixture is continuously in a dispersed state in the concrete, effectively preventing its precipitation. This ensures that the admixture concentration in each part of the concrete is uniform, thereby guaranteeing the consistency of the concrete performance. Whether it is compressive strength, impermeability, durability or other indicators, they can all reach a stable and relatively high level, improving the quality reliability of concrete products, reducing quality defects caused by admixture precipitation, and reducing potential risks in construction projects.

[0037] Furthermore: The support plates 1 symmetrically distributed on the outside of the mixing tank 2 provide solid and reliable support for the entire device. The support plates 1 are made of high-strength materials and can withstand the weight of the mixing tank 2 and the materials inside it, as well as the strong vibrations and impact forces generated during the mixing process, ensuring that the device does not shake, displace or other unstable phenomena during operation, guaranteeing the safety of the production process, and reducing the interference to concrete production caused by equipment instability.

[0038] Meanwhile: Scientific and reasonable connection methods are adopted between components such as the rotating shaft 52 and the mixing blades 53, the slider 66 and the slide rail convex plate 67, and the connecting rod 72 and the chute 71. These connections are carefully designed and tested, and can maintain stable connections under long-term high-load operating conditions, effectively reducing the probability of failures caused by problems such as component loosening and wear, extending the overall service life of the device, reducing maintenance costs and downtime, and improving the usage efficiency and economy of the equipment.

[0039] Embodiment 3, refer to Figures 1-8 , which is different from the above Embodiment 2 in that the rotating shaft 52 and the mixing blades 53 are rotatably connected inside the mixing tank 2, and a reciprocating mechanism 6 is fixedly connected to the top of the rotating shaft 52. The reciprocating mechanism 6 includes a stabilizing plate 61, and the stabilizing plate 61 is fixedly connected to the top of the mixing tank 2. A rotating disk 62 is arranged on the top of the stabilizing plate 61, and the center position of the bottom of the rotating disk 62 is fixedly connected to the top of the rotating shaft 52. A stabilizing column 63 is fixedly connected to the top of the rotating disk 62. A moving rod 64 is fixedly connected to the outside of the stabilizing column 63. One end of the moving rod 64 away from the stabilizing column 63 is fixedly connected to an adapter column 65, and a slider 66 is fixedly connected to the bottom of the adapter column 65. A slide rail convex plate 67 is arranged on the top of the stabilizing plate 61, and the slider 66 is slidably connected to the outside of the top of the slide rail convex plate 67.

[0040] Embodiment 4, refer to Figures 1-8 , which is different from the above Embodiment 3 in that the material extraction mechanism 7 includes a chute 71, and the chute 71 is opened inside the stabilizing plate 61. A connecting rod 72 is fixedly connected to the bottom of the slider 66, a pushing plate 73 is fixedly connected to the bottom of the connecting rod 72, a movable rod 74 is fixedly connected to the outside of the pushing plate 73. An injection tube 75 is arranged below the stabilizing plate 61. A piston cover 76 is fixedly connected to the outside of the movable rod 74, and the piston cover 76 is movably connected to the inside of the injection tube 75 through the movable rod 74. The top of the injection tube 75 is fixedly connected to a conduit 77, an admixture tank 78 is fixedly connected to the top of the stabilizing plate 61, and a transfer tank 710 is connected to the injection tube 75 through a connecting pipe 79.

[0041] Furthermore: The injection tube 75 is fixedly connected below the stabilizing plate 61 through the conduit 77. The transfer tank 710 is fixedly connected to the outside of the mixing tank 2. One-way valves are provided inside both the conduit 77 and the through pipe 79. The connecting rods 72 are symmetrically distributed at the bottom of the slider 66, and the connecting rods 72 are slidably connected inside the chute 71. The pushing plate 73 is movably connected below the stabilizing plate 61 through the connecting rods 72.

[0042] It should be noted that: The stabilizing plate 61, as the supporting component of the reciprocating mechanism 6, is made of thick metal plates to ensure that it does not deform when bearing the impact force of the reciprocating movement of the slider 66. High-strength bolts or welding are used at the connection parts of components such as the rotating disk 62, the stabilizing column 63, and the moving rod 64 to ensure firm connection. The surface of the slide rail convex plate 67 is hardened to improve wear resistance and extend service life. When the reciprocating mechanism 6 operates, it cleverly drives the injection tube 75 to extract the admixture from the admixture tank 78 to the transfer tank 710. This process is automatically completed without frequent manual operation, greatly reducing the labor intensity of workers and improving the extraction efficiency of the admixture. In the scenario of large-scale concrete production, it can quickly and stably complete the extraction work of the admixture, providing strong support for efficient continuous production. At the same time, it reduces the errors that may be brought by manual operation and ensures the accuracy of the extraction volume per batch.

[0043] Meanwhile: While the reciprocating mechanism 6 is operating, through the precise cooperation of components such as the toothed plate 82, the rotating gear 84, and the speed-changing gear 85 in the feeding mechanism 8, the baffle 88 is automatically opened to send the admixture in the transfer tank 710 to the mixing tank 2. The entire adding process does not require manual intervention, and the adding amount and adding timing can be precisely controlled. This meets the strict requirements for admixture addition in different concrete formulations, ensures a high degree of consistency in the quality of each batch of concrete, improves the controllability and stability of the production process, and reduces the quality fluctuations caused by inaccurate manual addition.

[0044] Specifically: The injection tube 75 and the piston cover 76 are made of corrosion-resistant materials such as stainless steel or special engineering plastics to adapt to the chemical properties of different admixtures. The diameters of the conduit 77 and the through pipe 79 are designed according to the flow requirements of the admixture to ensure smooth transportation of the admixture. The sealing materials of the one-way valves are selected from rubber or polytetrafluoroethylene that are resistant to chemical corrosion and wear, ensuring reliable one-way conduction performance.

[0045] Example Five, refer to Figures 1-8, different from the fourth embodiment above, the feeding mechanism 8 includes a fixed rod 81, and the fixed rod 81 is fixedly connected to the outside of the slider 66. A toothed plate 82 is fixedly connected to the outside of the fixed rod 81. An operating plate 83 is arranged on the outside of the transfer box 710. The toothed plate 82 is slidably connected to the outside of the operating plate 83. A rotating gear 84 is meshed and connected to the bottom of the toothed plate 82. A speed-changing gear 85 is meshed with the bottom of the rotating gear 84. A rotating rod 86 is fixedly connected to the central position of the speed-changing gear 85. A nylon rope 87 is wound around the outside of the rotating rod 86, and the bottom of the nylon rope 87 is fixedly connected to the top of the baffle plate 88. An outlet 89 is opened at the connection between the transfer box 710 and the mixing tank 2.

[0046] Furthermore: The rotating gear 84 and the speed-changing gear 85 are rotatably connected to the outside of the operating plate 83. The rotating rod 86 is rotatably connected above the transfer box 710. The feeding position of the through pipe 79 is between the baffle plate 88 and one inner wall of the transfer box 710, and the area of the baffle plate 88 is larger than the area of the outlet 89.

[0047] Still further: The rotating gear 84 and the speed-changing gear 85 are made of high-quality alloy steel, and are processed and heat-treated with high precision to ensure the meshing accuracy and strength of the gears. The tooth ratio of the gears is designed according to the requirement of the addition speed of the admixture. By adjusting the tooth ratio, the rotation speed of the rotating rod 86 can be accurately controlled, and then the opening speed of the baffle plate 88 can be controlled.

[0048] Specifically: The baffle plate 88 is made of corrosion-resistant and lightweight materials such as aluminum alloy or plastic. The connection part between it and the transfer box 710 uses a sealing strip to prevent the leakage of the admixture. The opening and closing actions of the baffle plate 88 should be flexible and smooth, and can be optimized by adjusting the length and tightness of the nylon rope 87.

[0049] It should be noted that: The mixing mechanism 5, the reciprocating mechanism 6, and the feeding mechanism 8 are cleverly coordinated in power through the rotating shaft 52. While the motor 51 drives the mixing, it supplies energy to the reciprocating mechanism 6, reducing the setting of additional power sources, lowering the equipment cost and energy consumption. This integrated design not only improves the energy utilization efficiency, but also streamlines the device structure, reduces the failure points, and enhances the stability and reliability of the equipment.

[0050] Specifically: The piston cover 76 in the pumping mechanism 7 cooperates with the injection pipe 75, and the gear set in the feeding mechanism 8 can accurately control the extraction amount and conveying amount of the admixture. For example, by adjusting the tooth ratio of the speed-changing gear 85, the rotation speed of the rotating rod 86 can be changed, and then the speed and amplitude of the nylon rope 87 pulling the baffle plate 88 can be accurately controlled, realizing the fine adjustment of the admixture addition amount and meeting the strict requirements of different concrete formulations for the admixture dosage.

[0051] Working principle: When in use, the controller 3 is turned on, and the motor 51 installed directly below the mixing tank 2 starts to work. The output end of the motor 51 drives the rotating shaft 52 to rotate, and the stirring blades 53 evenly and symmetrically connected to the outside of the rotating shaft 52 rotate inside the mixing tank 2 to stir the concrete entering the mixing tank 2 from the feed trough 4 to prevent the precipitation of concrete admixtures;

[0052] When the rotating shaft 52 rotates, the rotating disk 62 connected to its top rotates synchronously, and the stabilizing column 63, the moving rod 64, the connecting column 65 and the slider 66 fixed on the top of the rotating disk 62 make a circular motion with the rotating disk 62. Since the slider 66 slides on the slide rail convex plate 67 on the top of the stabilizing plate 61, the slider 66 will make a reciprocating linear motion along the slide rail convex plate 67. The connecting rods 72 symmetrically distributed at the bottom of the slider 66 slide in the slide groove 71 inside the stabilizing plate 61. The connecting rods 72 drive the push plate 73 below to make a reciprocating motion, and the movable rod 74 connected to the outside of the push plate 73 moves accordingly. The movable rod 74 drives the piston cover 76 to make a reciprocating motion in the injection tube 75. When the piston cover 76 moves outward, negative pressure is formed in the injection tube 75, and the additive in the additive box 78 is sucked into the injection tube 75 through the conduit 77. When the piston cover 76 moves inward, the additive in the injection tube 75 is pressed into the transfer box 710 through the through pipe 79. The one-way valves in the conduit 77 and the through pipe 79 ensure the one-way flow of the additive.

[0053] When the slider 66 reciprocates, the fixed rod 81 fixed on the outside drives the toothed plate 82 to slide on the outside of the running plate 83, and the toothed plate 82 meshes with the rotating gear 84, driving the rotating gear 84 to rotate, and the rotating gear 84 in turn drives the speed change gear 85 meshed therewith to rotate, and the rotating rod 86 at the center of the speed change gear 85 rotates synchronously, and the nylon rope 87 wound around the outside of the rotating rod 86 is retracted and released as the rotating rod 86 rotates. When the nylon rope 87 is retracted, the shielding plate 88 is pulled upward, and the middle The discharge port 89 at the connection between the transfer box 710 and the mixing tank 2 is opened, and the admixture in the transfer box 710 enters the mixing tank 2 through the discharge port 89 to mix with the concrete; when the nylon rope 87 is lowered, the baffle plate 88 falls back to close the discharge port 89, and the feeding position of the through pipe 79 is between the baffle plate 88 and the inner wall of one side of the transfer box 710, and the area of the baffle plate 88 is larger than the area of the discharge port 89, ensuring that the transportation and discharge control of the admixture are accurate and effective. Finally, the mixed concrete is discharged from the discharge pipe 54.
