Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing, in particular to a concrete admixture anti-sedimentation device. Background Art

[0002] At present, in the concrete production process, the use of admixtures is essential to improve the performance of concrete. However, many admixtures are prone to precipitation during storage and transportation, which seriously affects their use effect and concrete quality. Traditional admixture storage tanks are usually only equipped with simple stirring devices, which have poor stirring effects and cannot effectively prevent admixture precipitation.

[0003] In order to solve the above problems, the Chinese patent with application number: 202020772927.8 discloses an anti-sedimentation concrete admixture mixer, which, when in use, lifts up the hemisphere when the stirring blade passes through the hemispherical block, and then drives the piston plate to move up through the hemispherical block, thereby separating the discharge hole on the piston plate from the plug block, and then the admixture in the tank enters the mixing tank through the discharge hole on the piston plate, thereby achieving uniform addition of the admixture. However, before using the above technical solution, the user needs to put the admixtures into the admixture addition tank separately, and then add them evenly. This method increases the operating steps, which will affect the mixing efficiency of the admixture, and although it can stir and mix the admixtures in the mixing tank, it cannot process the admixtures remaining on the inner wall of the mixing tank, which leads to certain limitations in its mixing mechanism; The design of existing concrete mixing devices mainly focuses on the mixing function of concrete, and insufficient consideration is given to the anti-sedimentation and precise addition of admixtures. Although some mixing devices have simple mixing mechanisms, they cannot effectively prevent the precipitation of admixtures, resulting in the admixtures 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 of admixtures, and still rely on manual operation, which cannot meet the requirements of modern concrete production for efficiency and precision. In addition, existing mixing devices also have certain problems in structural stability and reliability, and are prone to loosening and wear of components during long-term operation, affecting the normal use of the device.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a concrete admixture anti-sedimentation device.

[0021] Example 1: Please refer to Figure 1-Figure 8 , a concrete admixture anti-sedimentation device, comprising a mixing tank 2, wherein a mixing mechanism 5 is provided inside the mixing tank 2, and the mixing mechanism 5 is used to mix the concrete inside the mixing tank 2; The top of the mixing tank 2 is provided with an extraction assembly, and the extraction mechanism includes a reciprocating mechanism 6 and a material extraction mechanism 7, and the material extraction mechanism 7 includes an injection tube 75, an additive box 78, and a transfer box 710. When the reciprocating mechanism 6 is in operation, the injection tube 75 is driven to extract the additive in the additive box 78 into the transfer box 710; A feeding mechanism 8 is arranged on the outside of the transfer box 710. The feeding mechanism 8 includes a baffle plate 88, and the baffle plate 88 is movably connected to the inside of the transfer box 710. When the reciprocating mechanism 6 is running, the baffle plate 88 opens to feed the additive inside the transfer box 710 out.

[0022] Example 2: See Figure 1-Figure 8 , which is different from the above-mentioned embodiment 1, a support plate 1 is fixedly connected to the outer side of the stirring tank 2, and the support plate 1 is symmetrically distributed on the outer side of the stirring tank 2, a controller 3 is arranged on the outer side of the support plate 1, a feed trough 4 is arranged on the outer side of the top of the stirring tank 2, a stirring mechanism 5 includes a motor 51, and the motor 51 is fixedly connected directly below the stirring tank 2, a rotating shaft 52 is fixedly connected to the output end of the motor 51, and stirring blades 53 are evenly and symmetrically connected to the outer side of the rotating shaft 52, and a discharge pipe 54 is arranged on the outer side of the stirring tank 2.

[0023] It should be noted that the stirring mechanism 5 drives the rotating shaft 52 and the stirring blades 53 through the motor 51 to fully stir the concrete in the mixing tank 2, forming a strong turbulence, so that the admixture is continuously in a dispersed state in the concrete, and its precipitation is effectively prevented. This ensures that the concentration of admixtures in various parts of the concrete is uniform, thereby ensuring the consistency of concrete performance. Whether it is compressive strength, impermeability or durability, etc., they can reach a stable and high level, thereby improving the quality reliability of concrete products, reducing quality defects caused by admixture precipitation, and reducing the potential risks of construction projects.

[0024] Specifically: 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 vibration and impact force generated during the mixing process, ensuring that the device will not experience unstable phenomena such as shaking and displacement during operation, thereby ensuring the safety of the production process and reducing interference with concrete production caused by equipment instability.

[0025] At the same time: scientific and reasonable connection methods are adopted between the rotating shaft 52 and the stirring blade 53, the slider 66 and the slide rail convex plate 67, the connecting rod 72 and the slide groove 71 and other components. These connections have been carefully designed and tested and can maintain stable connections under long-term high-load operating conditions, effectively reducing the probability of failures caused by loose components, wear and other problems, extending the overall service life of the device, reducing maintenance costs and downtime, and improving the efficiency and economy of the equipment.

[0026] Example 3, see Figure 1-Figure 8 , which is different from the above-mentioned embodiment 2, the rotating shaft 52 and the stirring blade 53 are rotatably connected to the inside of the stirring tank 2, and the top of the rotating shaft 52 is fixedly connected to a reciprocating mechanism 6, the reciprocating mechanism 6 includes a stabilizing plate 61, and the stabilizing plate 61 is fixedly connected to the top of the stirring tank 2, a rotating disk 62 is arranged on the top of the stabilizing plate 61, and the bottom center position 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, a connecting column 65 is fixedly connected to the end of the moving rod 64 away from the stabilizing column 63, a slider 66 is fixedly connected to the bottom of the connecting 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.

[0027] Example 4, see Figure 1-Figure 8 , which is different from the above-mentioned embodiment 3, the extraction mechanism 7 includes a slide groove 71, and the slide groove 71 opens the inside of the stabilizing plate 61, the bottom of the slider 66 is fixedly connected to a connecting rod 72, the bottom of the connecting rod 72 is fixedly connected to a pushing plate 73, the outer side of the pushing plate 73 is fixedly connected to a movable rod 74, an injection tube 75 is arranged below the stabilizing plate 61, the outer side of the movable rod 74 is fixedly connected to a piston cover 76, 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 the guide tube 77, the additive box 78 is fixedly connected to the top of the stabilizing plate 61, and the transfer box 710 is connected to the injection tube 75 through a through pipe 79.

[0028] Specifically, the injection tube 75 is fixedly connected to the bottom of the stabilizing plate 61 through the conduit 77, the transfer box 710 is fixedly connected to the outside of the mixing tank 2, and both the conduit 77 and the through pipe 79 are provided with a one-way valve, the connecting rod 72 is symmetrically distributed at the bottom of the slider 66, and the connecting rod 72 is slidably connected to the inside of the slide groove 71, and the push plate 73 is movably connected to the bottom of the stabilizing plate 61 through the connecting rod 72.

[0029] It should be noted that the stabilizing plate 61, as a supporting component of the reciprocating mechanism 6, is made of thick metal plates to ensure that it will not deform when subjected to the impact force of the reciprocating motion of the slider 66. The connecting parts of the rotating disk 62, the stabilizing column 63, the moving rod 64 and other components are made of high-strength bolts or welding to ensure a 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 is running, it cleverly drives the injection tube 75 to extract the admixture from the admixture box 78 to the transfer box 710. This process is completed automatically without the need for frequent manual operations, which greatly reduces the labor intensity of workers and improves the efficiency of admixture extraction. In large-scale concrete production scenarios, the admixture extraction work can be completed quickly and stably, providing strong support for efficient and continuous production, while reducing the errors that may be caused by manual operations to ensure the accuracy of the extraction amount of each batch.

[0030] At the same time: while the reciprocating mechanism 6 is running, through the precise coordination of the tooth plate 82, the rotating gear 84, the speed change gear 85 and the like in the feeding mechanism 8, the shielding plate 88 is automatically opened to deliver the admixture in the transfer box 710 to the mixing tank 2. The entire adding process does not require manual intervention, and the amount of addition and the timing of addition can be precisely controlled, which meets the strict requirements of different concrete formulas for the addition of admixtures, ensures the high consistency of the quality of each batch of concrete, improves the controllability and stability of the production process, and reduces the quality fluctuation caused by inaccurate manual addition.

[0031] 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 additives. The diameters of the conduit 77 and the through pipe 79 are designed according to the flow requirements of the additive to ensure that the additive can be smoothly transported. The sealing material of the one-way valve is made of chemically resistant and wear-resistant rubber or polytetrafluoroethylene to ensure reliable one-way conduction performance.

[0032] Example 5, see Figure 1-Figure 8 , which is different from the above-mentioned embodiment 4, the feeding mechanism 8 includes a fixed rod 81, and the fixed rod 81 is fixedly connected to the outer side of the slider 66, and a tooth plate 82 is fixedly connected to the outer side of the fixed rod 81. A running plate 83 is arranged on the outer side of the transfer box 710, and the tooth plate 82 is slidably connected to the outer side of the running plate 83. The bottom of the tooth plate 82 is meshed with a rotating gear 84, and the bottom of the rotating gear 84 is meshed with a speed change gear 85. The center position of the speed change gear 85 is fixedly connected with a rotating rod 86, and a nylon rope 87 is wound around the outer side of the rotating rod 86, and the bottom of the nylon rope 87 is fixedly connected to the top of the baffle plate 88. A discharge port 89 is provided at the connection between the transfer box 710 and the mixing tank 2.

[0033] Specifically, 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 to the top of the transfer box 710, 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.

[0034] Furthermore: the rotating gear 84 and the speed 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 gear ratio is designed according to the addition speed requirement of the admixture. By adjusting the gear ratio, the rotation speed of the rotating rod 86 can be accurately controlled, and then the opening speed of the baffle 88 can be controlled.

[0035] Specifically: the shielding plate 88 is made of corrosion-resistant, lightweight materials, such as aluminum alloy or plastic, and the connection between it and the transfer box 710 is sealed with a sealing strip to prevent leakage of the admixture. The opening and closing actions of the shielding plate 88 should be flexible and smooth, and can be optimized by adjusting the length and tightness of the nylon rope 87.

[0036] It should be noted that the stirring mechanism 5, the reciprocating mechanism 6 and the feeding mechanism 8 cleverly achieve power coordination through the rotating shaft 52. The motor 51 drives the stirring while supplying energy to the reciprocating mechanism 6, thereby reducing the setting of additional power sources, reducing equipment costs and energy consumption. This integrated design not only improves energy utilization efficiency, but also simplifies the device structure, reduces failure points, and enhances the stability and reliability of the equipment.

[0037] Specifically: the piston cover 76 in the extraction mechanism 7 cooperates with the injection tube 75, and the gear set in the feeding mechanism 8 can accurately control the extraction amount and delivery amount of the admixture. For example, by adjusting the gear ratio of the speed 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 88 can be accurately controlled, so as to achieve fine adjustment of the amount of admixture added and meet the strict requirements of different concrete formulas on the amount of admixture.

[0038] 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; 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. 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.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
