Technical Field

[0001] This utility model relates to the field of polymer mixing equipment, and in particular to a high-performance polymer slurry storage and mixing equipment that prevents sedimentation. Background Technology

[0002] In fields such as building construction and bridge construction, high-performance polymer grouting materials are widely used as key filling and reinforcement materials in prestressed duct grouting and other operations. Their performance stability directly affects the load-bearing capacity and durability of engineering structures.

[0003] To ensure that the grouting material remains uniformly mixed before use and to avoid a decline in construction quality due to component stratification, it is usually necessary to use specialized storage and mixing equipment for continuous processing to meet the strict performance requirements of the project for the grouting material.

[0004] However, conventional grout storage and mixing equipment has shortcomings in practical applications. Most equipment relies on a single mixing shaft to drive the mixing blades to rotate for mixing, and the mixing range is generally at the same height. This leads to the grout being prone to stratification during the mixing process, which in turn affects the uniformity of the grout and impacts its subsequent use. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a high-performance polymer grout storage and mixing device that prevents sedimentation. It aims to improve the problem that existing grout storage and mixing devices rely on a single mixing shaft to drive the mixing blades at the same height, which easily leads to grout stratification, affects grout uniformity, and hinders subsequent use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-performance polymer slurry storage and mixing device for preventing sedimentation, comprising a base, a support frame fixedly connected to the upper surface of the base, a mixing tank rotatably connected to the inner surface of the support frame, a feed pipe penetrating and fixedly connected to the top of the left surface of the mixing tank, a discharge pipe penetrating and fixedly connected to the bottom of the left surface of the mixing tank, a tank cover fixedly installed on the upper surface of the mixing tank by bolts, a protective frame fixedly connected to the upper surface of the base on the right side of the mixing tank, a drive assembly provided on the right side of the mixing tank, and a mixing assembly provided inside the mixing tank; The drive assembly includes a motor, which is located at the top of the inner wall of the protective frame. The output shaft of the motor is fixedly connected to a rotating shaft. A guide plate is fixedly connected to the upper surface of the rotating shaft. A guide ring is rotatably connected to the outer wall of the guide plate. One end of a connecting plate is hinged to the left surface of the guide ring. A hinge seat is hinged to the outer wall of the other end of the connecting plate. A groove is provided on the right surface of the mixing tank.

[0007] As a further description of the above technical solution: The stirring assembly includes a rotating rod, which is fixedly connected to the upper surface of the guide plate. A pulley is fixedly connected to the top of the outer wall of the rotating rod. A pulley is connected to the outer wall of the pulley via a transmission belt. A stirring shaft is fixedly connected through the inner wall of the pulley. A stirring blade is fixedly connected to the lower half of the outer wall of the stirring shaft. A guide hole is opened through the inner wall of the stirring blade.

[0008] As a further description of the above technical solution: The support frame is configured as a U-shape with the opening facing downwards, and valves are installed in the middle sections of both the discharge pipe and the feed pipe.

[0009] As a further description of the above technical solution: The rotating shaft passes through and is rotatably connected to the inner wall of the protective frame, and the guide plate is configured as a U-shape with the opening facing backward.

[0010] As a further description of the above technical solution: The hinge seat is slidably connected to the inner wall of the slide groove, and a trapezoidal protrusion is provided at the left end of the connecting plate. The cross-section of the slide groove from top to bottom is trapezoidal.

[0013] As a further description of the above technical solution: The guide hole is tapered with a large opening at the front and a small opening at the rear.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the driving component drives the mixing tank to swing back and forth in a pendulum-like manner around the support frame, thereby realizing the overall tumbling of the slurry inside the tank. At the same time, the mixing component drives the mixing blades to rotate, and the conical guide holes of the mixing blades form a velocity difference to enhance turbulence, thereby solving the problem of easy stratification when mixing alone, improving the uniformity of the slurry, and providing a stable guarantee for the quality of subsequent engineering construction.

[0015] In this invention, a single motor can synchronously drive the mixing tank to swing and the mixing blades to rotate, eliminating the need for multiple power sources and reducing energy consumption. Furthermore, the valves on the feed pipe and discharge pipe facilitate the control of raw material addition and slurry discharge, ensuring the ease of use of the device. Attached Figure Description

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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a high-performance polymer slurry storage and mixing device with anti-sedimentation properties, including a base 1 for supporting the overall device. The base 1 is flat, and a support frame 2 is fixedly connected to the upper surface of the base 1. A mixing tank 3 for mixing polymer slurry raw materials is rotatably connected to the inner surface of the support frame 2. A feed pipe 4 is fixedly connected through and to the top of the left surface of the mixing tank 3, and the polymer slurry raw materials are added through the feed pipe 4. A discharge pipe 5 is fixedly connected through and to the bottom of the left surface of the mixing tank 3, and the mixed polymer slurry is discharged from the discharge pipe 5. A tank cover 6 is fixedly installed on the upper surface of the mixing tank 3 by bolts. A protective frame 7 is fixedly connected to the upper surface of the base 1 on the right side of the mixing tank 3. The front surface of the protective frame 7 is provided with a door that can be rotated and opened to facilitate maintenance and replacement of internal components. A drive assembly 8 is provided on the right side of the mixing tank 3. The drive assembly 8 is used to drive the mixing tank 3 to generate a pendulum motion to improve the mixing effect and achieve high performance. A mixing assembly 9 for mixing polymer slurry raw materials is provided inside the mixing tank 3.

[0020] Reference Figures 3-5 The drive assembly 8 includes a motor 81, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The motor 81 is located at the top of the inner wall of the protective frame 7. The output shaft of the motor 81 is fixedly connected to a rotating shaft 82. A guide plate 83 is fixedly connected to the upper surface of the rotating shaft 82. The rotating shaft 82 will drive the guide plate 83 to rotate. A guide ring 84 is rotatably connected to the outer wall of the guide plate 83. One end of a connecting plate 85 is hinged to the left surface of the guide ring 84. The connecting plate 85 can swing up and down around the hinge point with the guide ring 84. A hinge seat 86 is hinged to the outer wall of the other end of the connecting plate 85. The connecting plate 85 can swing back and forth around the hinge point with the hinge seat 86. A vertical groove 87 is provided on the right surface of the mixing tank 3.

[0021] Reference Figures 3-5 The support frame 2 is configured as a U-shape with the opening facing downwards. Valves are installed in the middle sections of the discharge pipe 5 and the feed pipe 4. The valves are used to control the opening and closing of the discharge pipe 5 and the feed pipe 4. The rotating shaft 82 passes through and is rotatably connected to the inner wall of the protective frame 7. The guide plate 83 is configured as a U-shape with the opening facing backwards. When the guide plate 83 rotates, it will produce a circular motion that deviates from the center of the rotating shaft 82. The hinge seat 86 is slidably connected to the inner wall of the slide 87 and slides in the up and down direction. Under the transmission action of the guide ring 84, the connecting plate 85 and the hinge seat 86, the hinge seat 86 will produce a left and right direction movement, thereby pushing the mixing tank 3 to rotate around its and the support frame 2's rotation point. A trapezoidal protrusion is provided on the left end of the connecting plate 85. The cross-section of the slide 87 from top to bottom is set as a trapezoid.

[0022] Reference Figure 1 , Figure 3 , Figure 5 The stirring assembly 9 includes a rotating rod 91, which is fixedly connected to the upper surface of the guide plate 83. A pulley 92 is fixedly connected to the top of the outer wall of the rotating rod 91. A pulley 94 is connected to the outer wall of the pulley 92 via a transmission belt 93. Both the outer walls of the pulley 92 and the pulley 94 have tooth-shaped recesses. The inner wall of the transmission belt 93 has tooth-shaped protrusions that mesh with each other. A stirring shaft 95 is fixedly connected to the inner wall of the pulley 94. A stirring blade 96 is fixedly connected to the lower half of the outer wall of the stirring shaft 95. The stirring blade 96 is used to stir the polymer slurry raw material. A guide hole 97 is opened through the inner wall of the stirring blade 96.

[0023] Reference Figure 1 , Figure 3 , Figure 5 The center limits of the rotating shaft 82 and the rotating rod 91 are on the same vertical line. The upper surface of the can lid 6 has a notch, and the stirring shaft 95 passes through the notch, so that there will be no motion interference when the can lid 6 moves in a pendulum-like manner. The stirring shaft 95 passes through and is rotatably connected to the inner wall of the support frame 2. The support frame 2 provides support for the stirring shaft 95. The guide hole 97 is opened in the shape of a cone with a large opening at the front end and a small opening at the rear end, which can create a flow rate difference and improve the stirring effect.

[0024] Working principle: After the motor 81 is started, the output shaft of the motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 synchronously drives the guide plate 83 to make a circular motion. Since the guide ring 84 is sleeved on the outer wall of the guide plate 83, the circular motion of the guide plate 83 causes the guide ring 84 to deviate. Then, through the hinged connecting plate 85, the hinge seat 86 is pushed to slide up and down in the groove 87 on the right surface of the mixing tank 3. During this process, the mixing tank 3 swings back and forth in a pendulum manner with the sliding of the hinge seat 86 around the rotation connection point with the support frame 2 as the axis, realizing the overall turning of the polymer high-performance slurry in the tank, and initially avoiding the sedimentation of the slurry due to static standing.

[0025] Simultaneously, when the guide plate 83 rotates, it synchronously drives the rotating rod 91 on its surface to rotate. The pulley 92 at the top of the rotating rod 91 drives the pulley 94 to rotate through the transmission belt 93. The pulley 94 then drives the stirring shaft 95 to rotate inside the mixing tank 3. The stirring blades 96 on the outer wall of the stirring shaft 95 rotate with the shaft to stir and mix the slurry in the tank. The conical guide holes 97 with a large front opening and a small rear opening on the stirring blades 96 can form a slurry flow velocity difference during the stirring process, enhance the local turbulence effect, and further break the tendency of slurry agglomeration. Through the pendulum motion of the mixing tank 3 and the rotational stirring of the stirring blades 96, efficient anti-settling stirring of the high-performance polymer slurry is achieved, ensuring the uniformity of the slurry.

[0026] When it is necessary to discharge the slurry, open the valve of the discharge pipe 5, and the stirred slurry can be discharged stably along the discharge pipe 5. If it is necessary to add raw materials, open the valve of the feed pipe 4 to add them into the tank.

[0027] 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.
