Description

Technical Field

[0001] This utility model relates to the field of cement slurry mixing technology, and in particular to a cement slurry mixer for construction engineering. Background Technology

[0002] In the field of construction engineering, cement grout is a key material in core processes such as concrete preparation, wall construction, and foundation reinforcement. Its mixing uniformity directly determines the structural strength, durability, and construction quality of the project. As construction projects develop towards high-rise and large-span structures, the requirements for the mixing efficiency and uniformity of cement grout have significantly increased. It is necessary to meet the grout supply speed in large-scale construction scenarios while avoiding potential hazards such as structural cracks and insufficient strength caused by uneven grout mixing.

[0003] Currently, common cement slurry mixing machines on the market typically include a motor, transmission device, mixing drum, and mixing blades. The motor transmits power to the mixing blades inside the mixing drum through the transmission device, thereby agitating the slurry. During the mixing process, the mixing blades use their rotational motion to draw the slurry upwards from the bottom of the drum and then push it against the four walls of the drum, thus achieving the flow and mixing of the slurry.

[0004] However, during operation, existing mixers often have fixed mixing blades with a single rotation trajectory, which can easily lead to local eddies or dead zones in the cement slurry within the mixing tank. This results in uneven mixing and localized clumping of the slurry, which not only reduces the final quality of the cement slurry but also affects the mechanical properties and construction results of the concrete. Therefore, a cement slurry mixer for construction engineering is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to improve the uniformity of cement slurry mixing, aiming to address the problems of uneven mixing and local clumping that easily occur during mixing in existing mixers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cement slurry mixer for construction engineering includes a mixing tank and a support frame. The mixing tank is mounted on the top of the support frame. A support frame is fixedly connected to one end of the mixing tank. A second motor is fixedly connected to the side wall of the support frame. A coupling is fixedly connected to the output end of the second motor. A mixing component is mounted on one end of the coupling. The mixing assembly includes a drive shaft, one end of which is fixedly connected to one end of a coupling. Multiple tilting plates are fixedly connected to the outer wall of the drive shaft. The outer walls of the tilting plates are rotatably connected to the inner wall of the mixing tank. The inner wall of the mixing tank is provided with a limit assembly.

[0007] The above technical solution achieves the effect of uniformly mixing cement slurry inside the mixing tank. Preferably, the limiting component includes a limiting ring and a limiting block. The outer wall of the limiting ring is fixedly connected to the inner wall of the mixing tank, the side wall of the limiting block is fixedly connected to the side wall of the flip plate, and the side wall of the limiting block is slidably connected to the inner wall of the limiting ring.

[0008] The above technical solution achieves the effect of limiting the movement of the flip plate.

[0009] Preferably, a second support plate is fixedly connected to the top of the bracket, a first motor is fixedly connected to the side wall of the second support plate, a first rotating shaft is fixedly connected to the output end of the first motor, the side wall of the first rotating shaft is fixedly connected to the outer wall of the mixing tank, and the outer wall of the mixing tank is rotatably connected to the side wall of the second support plate.

[0010] The above technical solution achieves the effect of rotating the mixing tank.

[0011] Preferably, a first support plate is fixedly connected to the top of the bracket, a second rotating shaft is rotatably connected inside the first support plate, and the side wall of the second rotating shaft is fixedly connected to the outer wall of the mixing tank.

[0012] The above technical solution achieves a more stable rotation of the mixing tank.

[0013] Preferably, an L-shaped connecting plate is fixedly connected to the top of the bracket, and a soft block is slidably connected to the inner wall of the L-shaped connecting plate.

[0014] The above technical solution achieves the effect of buffering the mixing tank.

[0015] Preferably, a spring is provided on the inner wall of the L-shaped connecting plate, with one end of the spring fixedly connected to the inner wall of the L-shaped connecting plate and the other end of the spring fixedly connected to the side wall of the soft block.

[0016] The above technical solution achieves the effect of initial buffering of the mixing tank.

[0017] Preferably, a damping rod is fixedly connected to the inner wall of the L-shaped connecting plate, the output end of the damping rod is fixedly connected to the side wall of the soft block, and the outer wall of the damping rod is sleeved on the inner wall of the spring.

[0018] The above technical solution achieves a secondary buffering effect on the mixing tank.

[0019] Preferably, the outer wall of the mixing tank is provided on the soft block sidewall, and the soft block sidewall is slidably connected to the inner wall of the L-shaped connecting plate.

[0020] The above technical solution effectively mitigates the impact force generated when the mixing tank rotates.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the coupling and transmission shaft are driven to rotate by a second motor. During the rotation of the transmission shaft, the flipping plate on the outer wall is driven to rotate. The rotation of the flipping plate will drive the limiting block to rotate on the inner wall of the limiting ring, thereby achieving efficient and uniform mixing of cement slurry. This solves the problem that traditional mixers can only mix cement slurry in one direction, resulting in uneven mixing and local clumping of cement slurry, and improves the uniformity of cement slurry mixing.

[0022] 2. In this utility model, the first rotating shaft is driven by the first motor to rotate, and the rotation of the first rotating shaft will drive the mixing tank to rotate. At the same time, the rotation of the first rotating shaft will drive the second rotating shaft to rotate on the inner wall of the first support plate. After the mixing tank rotates to the designated position, it will squeeze the soft block on the side wall. The squeezing of the soft block will compress the spring and soft block on the side wall together, thereby achieving the effect of tilting the mixing tank for discharge and shock absorption and protection. This solves the problem that traditional mixers rely on the gravity of cement slurry to flow naturally from the discharge port, resulting in slow discharge speed of the mixing tank and excessive vibration that easily damages the equipment, and improves the service life of cement slurry mixing.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a cement slurry mixer for construction engineering, including a mixing tank 3 and a support 1. The mixing tank 3 is set on the top of the support 1. The mixing tank 3 is used to contain the cement slurry to be mixed, thereby providing a closed mixing space for the cement slurry, avoiding material waste and environmental pollution caused by slurry splashing during mixing. At the same time, it provides an installation carrier for internal components such as the tilting plate 11 and the limiting ring 13, ensuring the orderly operation of the internal structure. A support frame 8 is fixedly connected to one end of the mixing tank 3. A second motor 6 is fixedly connected to the side wall of the support frame 8. A coupling 7 is fixedly connected to the output end of the second motor 6. The coupling 7 rotates synchronously with the transmission shaft 10, thereby stably transmitting the power of the second motor 6 to the tilting plate 11, achieving the effect of ensuring that the tilting plate 11 continuously obtains power and efficiently mixes the cement slurry in the mixing tank 3. A mixing component is set at one end of the coupling 7. The mixing assembly includes a drive shaft 10, one end of which is fixedly connected to one end of a coupling 7. Multiple tilting plates 11 are fixedly connected to the outer wall of the drive shaft 10. These tilting plates 11 rotate along the inner wall of the mixing tank 3 under the drive of the drive shaft 10, creating multi-directional tumbling and shearing action on the cement slurry within the mixing tank 3. This breaks the static state of the slurry, ensuring uniform mixing of cement, water, and other additives, preventing slurry clumping and component stratification, and improving mixing quality and efficiency. The outer wall of the tilting plates 11 is rotatably connected to the inner wall of the mixing tank 3. A limiting assembly is provided on the inner wall of the mixing tank 3, including a limiting ring 13 and a limiting block 12. The limiting ring 13 is fixed to the inner wall of the mixing tank 3, providing an annular sliding track for the limiting block 12. This allows it to cooperate with the limiting block 12 to constrain the rotation range of the tilting plate 11, ensuring that the tilting plate 11 and the inner wall of the mixing tank 3 always maintain a reasonable gap. The outer wall of the limiting ring 13 is fixedly connected to the inner wall of the mixing tank 3, and the side wall of the limiting block 12 is fixedly connected to the side wall of the tilting plate 11. The side wall of the limiting block 12 is slidably connected to the inner wall of the limiting ring 13. The limiting block 12 cooperates with the limiting ring 13 to slide and rotate, thereby constraining the rotation range of the tilting plate 11. This achieves the effect of ensuring that the tilting plate 11 and the inner wall of the mixing tank 3 maintain a reasonable gap, avoiding collisions between components, and covering the entire mixing area.

[0027] Reference Figure 1 , Figure 2 and Figure 4The bracket 1 is fixedly connected to the top of a second support plate 5. The second support plate 5 is fixedly connected to the side wall of a first motor 4. The second motor 6 is connected to the first motor 4. The outer shell is made of HT200 gray cast iron, which serves to reduce vibration and noise, and protect the internal windings. The stator windings inside the motor are made of copper wire, which serves to reduce conductive loss and improve the energy conversion efficiency. This is existing technology and will not be described in detail here. The output end of the first motor 4 is fixedly connected to a first rotating shaft 9. The side wall of the first rotating shaft 9 is fixedly connected to the outer wall of the mixing tank 3. The mixing tank 3 is made of 304 stainless steel, which serves to resist the corrosion of alkaline substances in cement slurry and prevent the inner wall from rusting after long-term use, which could lead to slurry contamination or leakage of the mixing tank 3. The outer wall of the mixing tank 3 is rotatably connected to the side wall of the second support plate 5. The bracket 1 is fixedly connected to the top of a first support plate 2. The first support plate 2 is rotatably connected to the inside of the first support plate 2. The side wall of the second rotating shaft 18 is fixedly connected to the outer wall of the mixing tank 3.

[0028] Reference Figure 5 and Figure 6 An L-shaped connecting plate 14 is fixedly connected to the top of the bracket 1. The L-shaped connecting plate 14 is used to fix and install the spring 16 and the damping rod 17, and to provide sliding space for the soft block 15, thereby providing an installation carrier for the buffer assembly and ensuring that the buffer structure can accurately correspond to the outer wall of the mixing tank 3, so as to play a buffering role when the mixing tank 3 rotates into position. The soft block 15 is slidably connected to the inner wall of the L-shaped connecting plate 14. The soft block 15 is made of nitrile rubber, which has good elasticity and oil resistance, and can initially buffer the impact force when the mixing tank 3 is impacted. The inner wall of the L-shaped connecting plate 14 is provided with a spring 16. The spring 16 is used to be compressed when the soft block 15 slides, and absorbs the impact force generated by the squeezing of the mixing tank 3 through elastic deformation, thereby initially buffering the impact force when the mixing tank 3 rotates into position. To reduce vibration transmission to structures such as support plate 1 and support plate 1, one end of spring 16 is fixedly connected to the inner wall of L-shaped connecting plate 14, and the other end of spring 16 is fixedly connected to the side wall of soft block 15. A damping rod 17 is fixedly connected to the inner wall of L-shaped connecting plate 14. Spring 16 and damping rod 17 move in extension and retraction, thereby absorbing the impact force of mixing tank 3 and slowing down the rebound speed. This achieves the effect of initial buffering of vibration, avoiding secondary oscillation, reducing hard wear of equipment parts, and extending the overall service life of the mixer. The outer wall of damping rod 17 is sleeved on the inner wall of spring 16, and the other end of damping rod 17 is fixedly connected to the side wall of soft block 15. The outer wall of mixing tank 3 is set on the side wall of soft block 15, and the side wall of soft block 15 is slidably connected to the inner wall of L-shaped connecting plate 14.

[0029] Working principle: When using the cement slurry mixer for construction engineering, the material to be mixed is first poured into the mixing tank 3 through the opening at one end. Then, when mixing the cement slurry, the coupling 7 is driven to rotate by the output end of the second motor 6. Then, the coupling 7 drives the transmission shaft 10 to rotate. Then, the transmission shaft 10 rotates and drives the tilting plate 11 to rotate on the inner wall of the mixing tank 3. Then, the tilting plate 11 mixes the slurry on the inner wall of the mixing tank 3. The tilting plate 11 can form a multi-directional turning and shearing action on the cement slurry inside the mixing tank 3. Then, the tilting plate 11 rotates and drives the limiting block 12 on the side wall to rotate. Then, the limiting block 12 rotates on the inner wall of the mixing tank 3. The tilting plate 11 is limited by the limiting block 12 and the limiting ring 13, ensuring that the tilting plate 11 and the inner wall of the mixing tank 3 maintain a reasonable gap, so as not to collide and damage the parts, and to cover all areas inside the mixing tank 3. When the angle of the mixing tank 3 needs to be adjusted, the first motor 4 is started, and its output drives the first rotating shaft 9 to rotate. The first rotating shaft 9 directly drives the mixing tank 3 to rotate around its own axis. At the same time, the second rotating shaft 18 on the other side of the mixing tank 3 moves synchronously within the rotating hole of the first support plate 2, forming a double-sided support rotation structure. This balances the rotational force on the mixing tank 3, avoids axial offset caused by unilateral drive, and ensures that the mixing tank 3 rotates accurately to the target angle and stays stably. At the moment the mixing tank 3 reaches its rotation position, one end of the mixing tank 3 is positioned downwards. After the cement slurry remaining inside the mixing tank 3 is fully discharged, the outer wall of the mixing tank 3 will squeeze the soft block 15 inside the L-shaped connecting plate 14. The soft block 15 slides into the L-shaped connecting plate 14 under force, while compressing the spring 16 on the inner wall. The spring 16 absorbs the impact force generated by the squeezing of the mixing tank 3 through elastic deformation, and initially buffers the vibration. The damping rod 17 sleeved inside the spring 16 can play a damping role, slowing down the rebound speed of the soft block 15 and the spring 16, avoiding secondary vibration, reducing hard wear of equipment parts, and extending the overall service life of the mixer.
