Description

Technical Field

[0001] This utility model relates to the technical field of mixing tanks, and more particularly to a concrete mixing tank. Background Technology

[0002] Concrete, as a core material in contemporary civil engineering, occupies a pivotal position in modern building systems. It is an artificial stone material formed by mixing cement as the main binder with water, sand, and gravel in a scientific ratio, and adding chemical admixtures and mineral additives according to project requirements, through processes such as mixing, molding, and curing.

[0003] Currently, concrete mixing mainly relies on mixing tanks. However, traditional mixing tanks mostly use a rotary mixing method with built-in spiral blades. This operating mode also has some drawbacks: firstly, the concrete needs to be continuously mixed for a long time to reach the ideal mixing state, which affects construction efficiency; secondly, this mixing method may also cause material sedimentation and stratification, resulting in uneven mixing of concrete and affecting the quality of the finished product. Utility Model Content

[0012] Specifically, the stirring device includes a support shaft, a drive mechanism, and a stirring frame.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The concrete mixing tank of this utility model is described below with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the concrete mixing tank of this embodiment may include a tank body 10, a plurality of first mixing mechanisms 20, a plurality of second mixing mechanisms 30, and a mixing device 40. The plurality of first mixing mechanisms 20 and the plurality of second mixing mechanisms 30 are sequentially arranged around the inner wall of the tank body 10, and the plurality of first mixing mechanisms 20 and the plurality of second mixing mechanisms 30 are staggered to ensure comprehensive and uniform mixing. For example, the plurality of first mixing mechanisms 20 may be 3, 4, 5, 6, or 7, etc., and the specific number can be selected according to actual conditions, which is not limited here. The mixing device 40 is rotatably disposed in the middle of the tank body 10. It should be noted that the second mixing mechanism 30 described in this embodiment may include a plurality of equally spaced conical rods 31, which are vertically arranged on the inner wall of the tank body 10. For example, the plurality of conical rods 31 may be 2, 3, 4, or 5, etc., and the specific number can be set according to actual conditions, which is not limited here.

[0022] Understandably, when materials flow within the tank, the conical surface of the conical rod 31 exerts a unique force on the materials. Upon contact with the conical rod 31, the materials are compressed and diverted along the shape of the conical surface, resulting in more thorough mixing between the material particles. For example, when mixing highly viscous concrete, the conical rod 31 can effectively break up material agglomeration and improve mixing quality.

[0023] In this embodiment, the tank 10 is cylindrical in shape, with one end being an open structure for feeding concrete raw materials and discharging the mixed concrete, and the other end being a sealed structure to ensure that the materials do not leak during the mixing process and to provide a stable support environment for the internal mixing components.

[0024] To clearly illustrate the above embodiments, in one embodiment of this utility model, as follows: Figure 2As shown, the first mixing mechanism 20 may include a U-shaped mixing rod 21 and multiple connecting rods 22. The opening of the U-shaped mixing rod 21 faces the middle of the tank 10, and both ends of the U-shaped mixing rod 21 extend outward. There is a gap between the U-shaped mixing rod 21 and the inner wall of the tank 10. This design allows the U-shaped mixing rod 21 to effectively agitate the concrete material near the inner wall of the tank when rotating, while avoiding collision damage with the inner wall of the tank.

[0025] Multiple connecting rods 22 are distributed at intervals along the edge of the U-shaped stirring rod 21. For example, there may be 2, 3, 4, or 5 connecting rods 22. The specific number used can be selected according to the actual situation and is not limited here. One end of the connecting rod 22 is fixedly connected to the U-shaped stirring rod 21, and the other end of the connecting rod 22 is fixedly connected to the tank body 10.

[0026] Understandably, multiple connecting rods 22 are evenly spaced along the edge of the U-shaped stirring rod 21. One end of the connecting rod 22 is connected to the U-shaped stirring rod 21 by a reliable fixing method such as welding, and the other end is also firmly fixed to the tank body 10, thereby ensuring the stability of the U-shaped stirring rod 21 during the stirring process.

[0027] During the mixing process, the U-shaped stirring rod 21 rotates, drawing more material into its internal space and then ejecting it as it rotates, enhancing the mixing and agitation effect. Maintaining a distance between the U-shaped stirring rod 21 and the inner wall of the tank prevents hard friction and collision between the rod and the tank wall during high-speed rotation, extending the service life of both the stirring rod and the tank. Multiple connecting rods 22 are spaced apart along the edge of the U-shaped stirring rod 21. Besides providing a fixing function, these connecting rods 22 also disturb the surrounding material during mixing, further promoting the blending process.

[0028] Furthermore, in one embodiment of this utility model, such as Figure 3 As shown, the stirring device 40 may include a support shaft 41, a drive mechanism 42, and a stirring frame 43, wherein the support shaft 41 is vertically and rotatably mounted on the bottom wall of the inner cavity of the tank 10.

[0029] The drive mechanism 42 is mounted on the bottom wall of the tank 10, and its output end is connected to the support shaft 41. The stirring frame 43 is sleeved and fixed on the support shaft 41, and multiple through holes 401 are provided around the stirring frame 43. The center lines of the through holes 401 and the center line of the support shaft 41 are arranged in a cross shape, so that when the stirring frame 43 rotates, the material can be more fully convected and mixed through the through holes 401. For example, the material inside near the support shaft 41 can be thrown to the outside through the through holes 401, while the material outside can enter the inside, which enhances the convective mixing of the material and improves the stirring efficiency and uniformity.

[0030] It should be noted that the drive mechanism 42 described in this embodiment may be a drive motor.

[0031] Specifically, during concrete mixing, cement, water, sand, gravel, and any chemical admixtures and mineral additives that may be added are first poured into the tank 10 through its open end. An external drive device (which may include an external gear ring and a geared motor, wherein the external gear ring is fitted and fixed to the tank 10, and the gear meshes with the external gear ring) drives the tank 10 to rotate. Simultaneously, the drive mechanism 42 is activated, causing the support shaft 41 to rotate at high speed (the rotation direction of the support shaft 41 is opposite to the rotation direction of the tank 10), thereby causing the mixing frame 43, which is fitted onto the support shaft 41, to rotate accordingly. During rotation, the mixing frame 43, on the one hand, stirs and agitates the material in the middle of the tank 10 due to its own structure. On the other hand, through the surrounding through-holes 401, the material, under the combined action of centrifugal force and stirring force, forms convection inside and outside the mixing frame 43, promoting material mixing.

[0032] Meanwhile, since the first stirring mechanism 20 and the second stirring mechanism 30 are staggered on the inner wall of the tank 10, when the stirring device 40 drives the material inside the tank 10 to rotate as a whole, the U-shaped stirring rod 21 of the first stirring mechanism 20, during rotation, utilizes its special shape and the interval with the inner wall of the tank 10 to agitate and stir the material, drawing back any material that may have settled or been insufficiently mixed near the inner wall of the tank 10 into the stirring area. The multiple connecting rods 22 not only fix the U-shaped stirring rod 21 but also disturb the material to a certain extent. During the material flow, the conical rod 31 of the second stirring mechanism 30, with its conical shape, exerts a squeezing and diverting effect on the material, further refining the mixing between material particles and preventing material sedimentation and stratification.

[0033] Throughout the mixing process, the mixing device 40, the first mixing mechanism 20, and the second mixing mechanism 30 work together to mix the concrete materials from different positions and angles, greatly shortening the time required for the concrete to reach a uniform mixing state and improving construction efficiency. At the same time, it avoids the problem of material sedimentation and stratification, ensuring the uniformity of concrete mixing and thus improving the quality of the finished concrete product.

[0034] In summary, the concrete mixing tank of this utility model can effectively shorten the concrete mixing time, greatly improve construction efficiency, and at the same time avoid material sedimentation and stratification, ensure the uniformity of concrete mixing, and improve the quality of finished products.
