Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a concrete admixture storage tank. Background Technology

[0002] Concrete admixtures are chemical substances added during the concrete mixing process to improve concrete performance. By using different types of admixtures such as water-reducing agents, retarders, and accelerators, the workability of fresh concrete can be significantly improved, the heat of hydration reduced, setting time adjusted, and the strength and durability of hardened concrete enhanced. Therefore, the correct use of admixtures is an indispensable key step in the production of modern high-performance concrete, and the quality stability and component homogeneity of the admixtures before addition to concrete are prerequisites for ensuring they achieve their intended effects.

[0003] Currently, storage of liquid or slurry-like concrete admixtures typically employs tanks with integrated mixing capabilities. The commonly used structure involves installing a mixing motor at the top center of the tank, with the motor's output shaft extending vertically downwards into the tank's interior. One or more mixing blades are fixedly mounted on the output shaft. When mixing of the admixtures within the tank is required, the mixing motor is activated, driving the mixing blades to rotate in the liquid, thus creating a flow field that agitates the admixtures within the tank, achieving uniform mixing of their components. This built-in mixing structure is currently the most common and conventional technique in this field.

[0004] However, traditional storage tanks with built-in rotating agitators have inherent drawbacks in practical applications, such as insufficient mixing and the formation of mixing dead zones. Because the agitator blades are typically small relative to the tank body, their agitation is mainly concentrated in the central area, while the fluid disturbance effect is drastically reduced at the bottom edges, corners, and areas near the tank walls, creating mixing "dead zones." For some easily sedimenting suspension or emulsion admixtures, after prolonged settling, their active ingredients will redeposit and accumulate in these mixing dead zones, forming a high-concentration sediment layer. Even when agitation is started, the sediment in these areas is difficult to effectively flush away and stir up, resulting in a concentration stratification phenomenon in the admixture throughout the tank, with a clear upper layer and a thick lower layer, failing to achieve true overall uniformity. Therefore, a concrete admixture storage tank is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete admixture storage tank, aiming to improve the defects of traditional built-in mixing paddle tanks, such as insufficient mixing and the easy formation of mixing dead zones. The mixing effect is concentrated in the center, with poor effect in the bottom and edge areas, leading to admixture sedimentation and accumulation, resulting in concentration stratification and failing to achieve overall uniformity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete admixture storage tank, comprising a mobile vehicle, a support frame fixedly connected to the upper surface of the mobile vehicle, a connecting shaft rotatably connected inside the support frame, a fixing ring fixedly connected to one end of the connecting shaft, a storage tank fixedly connected inside the fixing ring, an inlet pipe fixedly connected to the upper surface of the storage tank, and a shaking component installed on the outer wall of the connecting shaft.

[0007] The oscillation assembly includes a gear, which is internally fixedly connected to the outer wall of a connecting shaft. A slide rail is fixedly connected to the outer wall of the support frame near the gear. A rack plate is slidably connected to the outer wall of the slide rail, and the rack plate meshes with the gear teeth. A connecting shaft is fixedly connected to one side of the outer wall of the rack plate. A support plate is fixedly connected to the upper surface of the moving vehicle near the outer wall of the support frame. A limiting groove is formed through the inside of the support plate. A hydraulic cylinder is provided on the outer wall of the support plate near the limiting groove. A hinge seat is fixedly connected to the output end of the hydraulic cylinder.

[0008] As a further description of the above technical solution:

[0009] A motor is fixedly connected to the upper surface of the storage tank, a stirring shaft is fixedly connected to the output end of the motor, and a U-shaped frame is fixedly connected to the outer wall of the stirring shaft.

[0010] As a further description of the above technical solution:

[0011] A scraper is slidably connected inside the U-shaped frame, and the outer wall of the scraper abuts against the inner wall of the storage tank.

[0012] As a further description of the above technical solution:

[0013] A sliding plate is fixedly connected to one side of the outer wall of the scraper, and a limiting block is fixedly connected to one side of the outer wall of the sliding plate. The outer wall of the limiting block is slidably connected in a groove inside the U-shaped frame.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the U-shaped frame is provided with a telescopic rod, and the outer wall of the telescopic rod is fitted with a spring.

[0016] As a further description of the above technical solution:

[0017] One end of the telescopic rod is fixedly connected to one side of the inner wall of the U-shaped frame, and the other end of the telescopic rod is fixedly connected to the outer wall of the sliding plate.

[0018] As a further description of the above technical solution:

[0019] One end of the spring is fixedly connected to one side of the inner wall of the U-shaped frame, and the other end of the spring is fixedly connected to one side of the outer wall of the sliding plate.

[0020] As a further description of the above technical solution:

[0021] The hinge seat is rotatably connected to the second connecting shaft, and the outer wall of the second connecting shaft is slidably connected to the inner wall of the limiting groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by activating the hydraulic cylinder, its output end drives the rack plate to reciprocate linearly under the guidance of the limiting inclined groove via the hinge seat and connecting shaft 2. Due to the meshing transmission between the rack plate and the gear, its linear motion is converted into the reciprocating rotational motion of the gear, thereby driving the connecting shaft 1 and the entire storage tank to periodically sway and shake. This design, through external forced shaking, can comprehensively, gently, and uniformly stir the concrete admixture stored in the tank, effectively preventing component sedimentation or stratification that may occur during long-term static storage of the admixture, ensuring the concentration uniformity and performance stability of the admixture during use. This shaking mechanism is located outside the tank and does not directly contact the material, avoiding the problem of uneven stirring that may be caused by a single stirring paddle. The structure is reliable and maintenance is convenient.

[0024] 2. In this invention, starting the motor at the top of the storage tank drives the stirring shaft and the U-shaped frame fixed thereon to rotate. Inside the U-shaped frame, the elastic pushing action of springs and telescopic rods ensures that the scraper remains tightly attached to the inner wall of the storage tank. As the stirring shaft rotates, the scraper simultaneously and continuously scrapes the inner wall of the storage tank. This design effectively solves the problem of some admixtures, due to their high viscosity, easily adhering to and forming a crust on the tank wall. Through continuous physical scraping, not only is material adhesion and waste prevented, ensuring the cleanliness of the storage tank interior, but the risk of contamination of newly added admixtures by hardened crusts is also avoided, further guaranteeing the quality of the admixtures. This dynamic wall scraping function, combined with the overall shaking and mixing function, greatly enhances the practical value of the equipment. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-5 An embodiment of this utility model provides: a concrete admixture storage tank, including a mobile vehicle 1, a support frame 2 for supporting the tank body and related components fixedly connected to the upper surface of the mobile vehicle 1, a connecting shaft 3 serving as the rotation center axis of the storage tank 6 rotatably connected inside the support frame 2, a fixing ring 4 for clamping and fixing the storage tank 6 fixedly connected to one end of the connecting shaft 3, a storage tank 6 serving as an admixture storage container fixedly connected inside the fixing ring 4, an inlet pipe 5 for facilitating the addition of materials into the tank fixedly connected to the upper surface of the storage tank 6, and a shaking component installed on the outer wall of the connecting shaft 3;

[0034] The swaying assembly includes a gear 7, which serves as the core transmission component for converting linear motion into rotational motion. The gear 7 is internally fixedly connected to the outer wall of the connecting shaft 3. A slide rail 8, which provides stable linear motion guidance for the rack plate 9, is fixedly connected to the outer wall of the support frame 2 near the gear 7. The rack plate 9, which serves as a power transmission actuator, is slidably connected to the outer wall of the slide rail 8. The rack plate 9 meshes with the tooth ends of the gear 7. A connecting shaft 10, which connects the power source to the rack plate 9, is fixedly connected to one side of the outer wall of the rack plate 9. A support plate 11, which provides a mounting base and guide structure for the swaying mechanism, is fixedly connected to the upper surface of the moving vehicle 1 near the outer wall of the support frame 2. A limiting groove 12 is formed through the support plate 11. A hydraulic cylinder 13, which serves as the power source for driving the entire swaying assembly, is provided on the outer wall of the support plate 11 near the limiting groove 12. A hinge seat 14 is fixedly connected to the output end of the hydraulic cylinder 13. The hinge seat 14 is rotatably connected to the connecting shaft 10, and the outer wall of the connecting shaft 10 is slidably connected to the inner wall of the limiting groove 12.

[0035] Specifically, during operation, the hydraulic cylinder 13 provides reciprocating thrust, which is transmitted to the rack plate 9 via the hinge seat 14 and the connecting shaft 10. Under the combined action of the limiting groove 12 and the slide rail 8, the rack plate 9 performs reciprocating linear motion along a set trajectory. Due to the meshing transmission relationship between the rack plate 9 and the gear 7, this linear motion is stably converted into the reciprocating rotational motion of the gear 7, which in turn drives the connecting shaft 3 and the entire storage tank 6 to perform periodic swaying and shaking, thereby achieving overall and uniform stirring of the material in the tank and effectively preventing the precipitation and stratification of the additives.

[0036] Reference Figures 1-5 A motor 15, serving as the power source for the wall scraping mechanism, is fixedly connected to the upper surface of the storage tank 6. A stirring shaft 16, used for transmitting power, is fixedly connected to the output end of the motor 15. A U-shaped frame 17, serving as a mounting bracket for the scraper 20, is fixedly connected to the outer wall of the stirring shaft 16. A scraper 20, used for scraping off deposits on the inner wall, is slidably connected inside the U-shaped frame 17. The outer wall of the scraper 20 abuts against the inner wall of the storage tank 6 during operation. A sliding plate 18, serving as a support for the scraper 20, is fixedly connected to one side of the outer wall of the scraper 20. A limiting block 19 is fixedly connected to one side of the outer wall of the sliding plate 18, and the outer wall of the limiting block 19 is slidably connected to the U-shaped frame 17. The groove inside the frame 17 is used to guide the scraper 20 to move radially in a stable manner. In order for the scraper 20 to elastically conform to the tank wall, the inner wall of the U-shaped frame 17 is provided with a telescopic rod 21 for support and guidance. The outer wall of the telescopic rod 21 is fitted with a spring 22 to provide a continuous pushing force. One end of the telescopic rod 21 is fixedly connected to one side of the inner wall of the U-shaped frame 17, and the other end of the telescopic rod 21 is fixedly connected to the outer wall of the sliding plate 18. One end of the spring 22 is fixedly connected to one side of the inner wall of the U-shaped frame 17, and the other end of the spring 22 is fixedly connected to one side of the outer wall of the sliding plate 18, together forming a set of elastic pushing device.

[0037] Specifically, after starting the motor 15, it drives the stirring shaft 16 and the U-shaped frame 17 to rotate synchronously. Inside the U-shaped frame 17, the spring 22 continuously generates elastic potential energy, which, through the telescopic rod 21 and the sliding plate 18, applies a constant, outward thrust to the scraper 20, allowing it to tightly and elastically contact the inner wall of the storage tank 6. As the U-shaped frame 17 rotates, the scraper 20 continuously and physically scrapes the entire inner circumference of the tank, effectively solving the problems of wall adhesion and crusting caused by the viscosity of the material, ensuring the cleanliness of the tank and the effective utilization rate of the material.

[0038] Working principle: When the storage tank is needed, the hydraulic cylinder 13 mounted on the mobile vehicle 1 is first activated. Its output end pushes the connecting shaft 10 through the hinge seat 14. The connecting shaft 10, guided and constrained by the limiting groove 12 inside the support plate 11, drives the rack plate 9 fixed to it to perform reciprocating linear motion. Since the rack plate 9 and the gear 7 fixed on the connecting shaft 3 are always meshed, the linear motion of the rack plate 9 is precisely converted into the reciprocating rotational motion of the gear 7. This rotational motion then drives the connecting shaft 3 and the entire storage tank 6 connected to it through the fixing ring 4 to periodically sway and shake around the connecting shaft 3. This externally driven overall shaking can produce a gentle and comprehensive flow of liquid in the tank, effectively overcoming the mixing dead zone problem caused by traditional internal stirring paddles.

[0039] Secondly, the motor 15 installed on top of the storage tank 6 can be started. The motor 15 drives the stirring shaft 16 and the U-shaped frame 17 fixed thereon to rotate. Inside the U-shaped frame 17, the scraper 20 can slide radially through the sliding plate 18. The spring 22 and the telescopic rod 21 together form an elastic support mechanism, continuously applying an outward thrust to the sliding plate 18, which allows the front end of the scraper 20 to always be in close contact with the inner wall of the storage tank 6. Therefore, when the U-shaped frame 17 rotates, the scraper 20 simultaneously and continuously scrapes the inner wall of the tank, scraping off the attached material, preventing it from crusting and accumulating, and ensuring the cleanliness of the tank and the effective utilization rate of the material.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
