Description

Technical Field

[0001] The present invention relates to the technical field of construction, and specifically to a production and mixing device for fluidized solidified soil. Background Art

[0002] Construction is a complex and systematic project, covering a series of operations from foundation construction to overall construction. Among them, the processing of basic materials such as cement, clay or stone is a key link. As a special material composed of cement and other materials, fluidized solidified soil is widely used in scenarios such as building foundation treatment and road cushion construction due to its good fluidity and strength characteristics after curing. To fully utilize the performance advantages of fluidized solidified soil, it is necessary to rely on an efficient and precise mixing device to achieve uniform mixing of various component materials.

[0003] Existing mixing devices for manufacturing mixtures of cement and other materials (such as fluidized solidified soil) have many deficiencies. From the perspective of the control of the mixing device, the control systems of most current devices have a low degree of intelligence and cannot dynamically adjust the mixing parameters according to the real-time state of the materials (such as the humidity and particle size of the materials), resulting in overloading of the mixing motor, which not only affects the mixing efficiency but may also damage the equipment. Moreover, during the mixing process of the existing mixing devices, the mixing effect of materials with different densities and particle sizes is not good. Since the mixing blades are relatively single, they cannot effectively drive large particle size stones to be fully mixed with fine particle materials such as cement and clay, and cannot be applied to a variety of mixing occasions, resulting in uneven local components in the fluidized solidified soil after mixing, reducing the overall performance of the material and not meeting the strict requirements of construction for high-quality and stable materials.

Specific embodiments

[0028] The following will refer to the accompanying drawings of the specification to describe the embodiments of the present invention in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0029] Embodiment:

[0030] Please refer to Figures 1 to 11 , a production and mixing device for fluid-solidified soil and its use method, including a base 1, on the upper surface of the base 1 are respectively fixedly connected with a mixing tank 10 and a PLC programmable logic controller 3, on the outer surface of the mixing tank 10 are fixedly connected with four stabilizing seats 2, and the bottom surface of each stabilizing seat 2 is fixedly connected with the upper surface of the base 1. A transmission mechanism is arranged on the right side of the mixing tank 10. A main rotating shaft 21 is arranged inside the mixing tank 10. The transmission mechanism is fixedly connected with a mixing and stirring unit through the main rotating shaft 21. An auxiliary stirring unit is fixedly connected to the outside of the main rotating shaft 21 through the mixing tank 10. Feed bins 9 and injection pipes 11 are respectively fixedly connected to the outer surface of the mixing tank 10.

[0031] Working principle: The base 1 of this device is the support foundation, on which the mixing tank 10 and the PLC programmable controller 3 are fixed. The stabilizing seat 2 ensures the stability of the mixing tank 10. The feeding bin 9 and the injection pipe 11 are responsible for the input of materials, preparing raw materials for the subsequent mixing operation. Among them, the transmission mechanism can rotate through the main rotating shaft 21, providing continuous power for the entire mixing device to ensure the stable operation of the device. The mixing and stirring unit can enable the stirring components to rotate flexibly, efficiently stir the materials, enhance the uniformity of material mixing, and the auxiliary stirring unit works in coordination with the mixing and stirring unit to optimize the stirring effect, prevent the materials from accumulating on the inner wall of the mixing tank 10, make the composition of the fluidized solidified soil more uniform, and improve the material performance.

[0032] Please refer to Figures 1 to 11 , the transmission mechanism includes two first sealing bearings 17 fixedly connected to the inner wall of the mixing tank 10. The inner ring of each first sealing bearing 17 is fixedly connected to the outer surface of the main rotating shaft 21. The left end of the main rotating shaft 21 is fixedly connected with a stepping motor 7. The outer surface of the right end of the main rotating shaft 21 is fixedly connected with a first main gear 18. The outer surface of the first main gear 18 is engaged with a first transmission gear 19. The inner wall of the first transmission gear 19 is fixedly connected with a transmission shaft 22. The outer surface of the left end of the transmission shaft 22 is fixedly connected with a first ball bearing 26. The outer surface of the first ball bearing 26 is fixedly connected to the inner wall of the mixing tank 10. An annular groove 23 is formed on the right side surface of the mixing tank 10. A double-ring positioning groove 24 is formed on the inner wall of the annular groove 23. Six driving shafts 16 are slidably connected inside the annular groove 23. Two limit balls 27 are fixedly connected to the outer surface of each driving shaft 16. The inner part of the double-ring positioning groove 24 is slidably connected with the outer surfaces of the two limit balls 27. The right ends of the six driving shafts 16 are fixedly connected together with a double-tooth meshing rotary cover 12. The outer surface of the first transmission gear 19 is engaged with the inner teeth of the double-tooth meshing rotary cover 12. The outer surface of the stepping motor 7 is fixedly connected with a frame 8. The right side surface of the frame 8 is fixedly connected to the left side surface of the mixing tank 10.

[0033] Working principle: The stepping motor 7 is installed on the frame 8, and the frame 8 is connected to the mixing tank 10. When the stepping motor 7 is started, it drives the main rotating shaft 21 to rotate. The first main gear 18 at the right end of the main rotating shaft 21 rotates and meshes with the first transmission gear 19, driving the transmission shaft 22 to rotate. The first ball bearing 26 ensures the stable rotation of the transmission shaft 22. The transmission shaft 22 drives the double-tooth meshing rotary cover 12 to rotate. The double-tooth meshing rotary cover 12 slides along the double-ring positioning groove 24 in the annular groove 23 through the driving shafts 16 and the limit balls 27, stably transmitting power to the mixing and stirring unit and the auxiliary stirring unit, solving the problems of mixing power transmission and conversion, and ensuring the coordinated operation of each part of the mixing device.

[0034] Please refer to Figures 1 to 11, the mixing and stirring unit includes three U-shaped stirring paddles 13 fixed on the outer surface of the main rotating shaft 21. A sealing unit is provided on the outer side of each U-shaped stirring paddle 13. A driving cavity 38 is formed inside each U-shaped stirring paddle 13. A plurality of telescopic openings 45 are formed on the outer surface of each U-shaped stirring paddle 13. The inside of each telescopic opening 45 communicates with the inside of the driving cavity 38. A plurality of stabilizing cylinders 32 and limiting plates 33 are fixedly connected to the inner wall of each driving cavity 38. A telescopic rod 39 is slidably connected inside each stabilizing cylinder 32. The top of each telescopic rod 39 penetrates through the telescopic opening 45 and extends to the outside of the U-shaped stirring paddle 13. A reset connecting plate 40 is fixedly connected to the outer surface of each telescopic rod 39. Two sleeve rods 41 are fixedly connected to the upper surface of each reset connecting plate 40. Two sleeves 34 are fixedly connected to the bottom surface of each limiting plate 33. The outer surface of each sleeve rod 41 is slidably connected to the inside of the sleeve 34. A compression spring 31 is fixedly connected to the inner wall of each sleeve 34 and one end of the sleeve rod 41 together. A counterweight ring 42 is fixedly connected to the outer surface of each telescopic rod 39.

[0035] Working principle: When the main rotating shaft 21 rotates, it drives the three U-shaped stirring paddles 13 to rotate synchronously. The telescopic rod 39 in the driving cavity 38 inside the U-shaped stirring paddle 13 realizes axial sliding through the guiding structure of the stabilizing cylinder 32 and the limiting plate 33. Its expansion and contraction are driven by centrifugal force. When the rotational speed increases, the counterweight ring 42 on the outer surface of the telescopic rod 39 is thrown outwards due to centrifugal force, driving the telescopic rod 39 to extend out from the telescopic opening 45. The compression spring 31 is compressed by the sleeve rod 41 and the sleeve 34 to store elastic potential energy. At this time, the extended telescopic rod 39 drives the mixing and stirring blades 37 to stir the material in a large range, which is suitable for the crushing and dispersion of large particle size stones. When the rotational speed decreases and the centrifugal force decreases, the compression spring 31 resets and pushes the telescopic rod 39 to retract. The mixing and stirring blades 37 contract to near the U-shaped stirring paddle 13, focusing on the fine mixing of fine particle materials such as cement and clay. At the same time, the stabilizing cylinder 32 restricts the radial displacement of the telescopic rod 39, and the limiting plate 33 restricts the axial stroke through the sleeve 34 and the sleeve rod 41 to avoid damage to the structure due to excessive expansion and contraction.

[0036] Please refer to Figures 1 to 11 , a tension spring 35 is fixedly connected to the inner wall of each driving cavity 38. One end of each tension spring 35 is fixedly connected to one end of the telescopic rod 39 close to the tension spring 35. Six mixing and stirring blades 37 are fixedly connected to the outer surface of the top of each telescopic rod 39.

[0037] Working principle: One end of the tension spring 35 in the driving cavity 38 is fixed to the telescopic rod 39, and the other end is fixed to the inner wall of the driving cavity 38. Its functions are reflected in assisting in resetting and tension adjustment. When the U-shaped stirring paddle 13 starts or the rotation speed suddenly changes, the tension spring 35 uses elastic tension to assist the telescopic rod 39 to quickly reset, avoiding telescopic lag caused by inertia. Moreover, when the telescopic rod 39 is in the extended state, the tension spring 35 provides continuous tension to ensure stable contact between the mixing and stirring blades 37 and the material and enhance the stirring force. At the same time, when the mixing and stirring blades 37 contact materials with high viscosity or large particle size, the material resistance compresses the tension spring 35 through the telescopic rod 39, causing the telescopic rod 39 to retract slightly. The elastic buffer reduces mechanical shock and avoids motor overload. This "soft contact" characteristic enables the stirring device to adapt to materials with different densities and improves the stirring compatibility.

[0038] Please refer to Figures 1 to 11 , the sealing unit includes a plurality of first conical sealing inner sleeves 48 and a plurality of conical sealing outer sleeves 36 fixed on the outer surface of each U-shaped stirring paddle 13. Each first conical sealing inner sleeve 48 is embedded inside the conical sealing outer sleeve 36. The inner wall of each driving cavity 38 is fixedly connected with a second conical sealing inner sleeve 47. The inner wall of each telescopic opening 45 is fixedly connected with three stainless steel sealing rings 49. The outer surface of each telescopic rod 39 is in contact with the inner wall of the first conical sealing inner sleeve 48, the inner wall of the conical sealing outer sleeve 36, the inner wall of the second conical sealing inner sleeve 47, and the inner wall of the three stainless steel sealing rings 49 respectively.

[0039] Working principle: In the sealing unit, the first conical sealing inner sleeve 48 is embedded inside the conical sealing outer sleeve 36. The second conical sealing inner sleeve 47 on the inner wall of the driving cavity 38 and the three stainless steel sealing rings 49 on the inner wall of the telescopic opening 45 closely fit the outer surface of the telescopic rod 39. Moreover, the first conical sealing inner sleeve 48 and the conical sealing outer sleeve 36 are conical, which can ensure that during the process of the telescopic rod 39 retracting into the U-shaped stirring paddle 13, the flowing and solidified soil during stirring is scraped off, effectively blocking the material from entering the driving cavity 38, protecting the internal transmission components, preventing material leakage, ensuring the normal operation of the transmission components, and extending the service life of the equipment.

[0040] Please refer to Figures 1 to 11, the auxiliary stirring unit includes six fixed ports 25 respectively opened on the left and right side surfaces of the stirring tank 10. The inner wall of each fixed port 25 is fixedly connected with a second sealing bearing 15. The inner rings of every two second sealing bearings 15 at the same level are jointly fixedly connected with an auxiliary rotating shaft 4. The outer surface of each auxiliary rotating shaft 4 is fixedly connected with a plurality of stirring auxiliary blades 14. The outer surface of the right end of each stirring auxiliary blade 14 is fixedly connected with a third transmission gear 20. The outer surface of each third transmission gear 20 meshes with the outer teeth of the double-tooth meshing cover 12. One end of each stirring auxiliary blade 14 is fixedly connected with a connecting disc 56. The outer surface of each connecting disc 56 is fixedly connected with a scraping plate 54. The outer surface of each scraping plate 54 is fixedly connected with a rubber scraping strip 55.

[0041] Working principle: When the double-tooth meshing cover 12 rotates, its outer teeth mesh with the third transmission gear 20, driving the auxiliary rotating shaft 4 to rotate, so that the stirring auxiliary blades 14 rotate. One end of the stirring auxiliary blade 14 is connected to the connecting disc 56. The scraping plate 54 and the rubber scraping strip 55 on the connecting disc 56 scrape the materials on the inner wall of the stirring tank 10, assisting the mixing and stirring unit to prevent the materials from adhering and accumulating on the tank wall, stirring the materials in all directions, making the mixing of the fluidized solidified soil more uniform, and improving the material quality.

[0042] Please refer to Figures 1 to 11 , a discharge pipe 6 is fixedly communicated with the left side surface of the stirring tank 10. A slurry pump 5 is fixedly communicated with the outer surface of the discharge pipe 6. The right side surface of the slurry pump 5 is fixedly connected with the left side surface of the stirring tank 10. A humidity sensor 28, a pressure sensor 29 and a particle size sensor 30 are respectively fixedly connected to the inner wall of the stirring tank 10. The PLC programmable controller 3 is electrically connected to the humidity sensor 28, the pressure sensor 29 and the particle size sensor 30 through wires respectively.

[0043] Working principle: After the stirring is completed, the slurry pump 5 is started to convey the stirred fluidized solidified soil out through the discharge pipe 6. The humidity sensor 28, the pressure sensor 29 and the particle size sensor 30 monitor the state of the materials in the stirring tank 10 in real time and transmit the data to the PLC programmable controller 3. The PLC programmable controller 3 intelligently adjusts the operating parameters of the stepping motor 7 according to the data, realizes precise control of the stirring process, and can also add other additives such as water through the injection pipe 11 to dilute the viscous solidified soil, assist in stirring, avoid overloading of the stirring motor, and ensure the stirring quality and stable operation of the equipment.

[0044] In summary, when the overall equipment is in use, the production and mixing device for fluid-solidified soil takes the base 1 as the support foundation, fixes the mixing tank 10 through the stabilizing seat 2 to ensure its stability. The PLC programmable controller 3 is integrated above the base 1 and is used to intelligently control the entire mixing process. Materials are transported into the mixing tank 10 through the feed bin 9 and the injection pipe 11. The injection pipe 11 can add water or additives as needed to adjust the state of the materials. The transmission mechanism takes the stepping motor 7 as the power source, which is fixed on the left side of the mixing tank 10 through the frame 8. After starting, it drives the main rotating shaft 21 to rotate. The main rotating shaft 21 realizes stable rotation through the first sealing bearings 17 at both ends. The first main gear 18 at the right end meshes with the first transmission gear 19, driving the transmission shaft 22 and the double-tooth meshing cover 12 to rotate. The double-tooth meshing cover 12 slides in the double-ring positioning groove 24 of the annular groove 23 through the drive shaft 16 and the limit ball 27, synchronously transmitting power to the mixing and auxiliary mixing units. In the mixing and auxiliary mixing units, the main rotating shaft 21 drives three U-shaped mixing paddles 13 to rotate. The telescopic rod 39 in the internal drive cavity 38 of the mixing paddle is guided by the stabilizing cylinder 32 and the limiting plate 33, and realizes telescoping by using the centrifugal force of the counterweight ring 42. When rotating at high speed, the counterweight ring 42 drives the telescopic rod 39 to extend, and the mixing and stirring blades 37 stir the large-sized stones in a large range. The compression spring 31 stores potential energy. When rotating at low speed, the tension spring 35 and the compression spring 31 reset, retracting the telescopic rod 39, focusing on the mixing of fine-grained materials. At the same time, the tension spring 35 assists in resetting and provides continuous tension, buffering the material resistance to avoid overload. The sealing unit uses the first conical sealing inner sleeve 48, the conical sealing outer sleeve 36, the second conical sealing inner sleeve 47 and the stainless steel sealing ring 49 to scrape the materials and seal the drive cavity 38 during the telescoping process of the telescopic rod 39 to prevent leakage. In the auxiliary mixing unit, the external teeth of the double-tooth meshing cover 12 drive the third transmission gear 20, driving the auxiliary rotating shaft 4 and the auxiliary mixing blades 14 to rotate. The scraper 54 and the rubber scraper strip 55 on the connecting disc 56 scrape the materials on the tank wall synchronously, avoiding accumulation and assisting in uniform mixing. During the mixing process, the humidity sensor 28, the pressure sensor 29 and the particle size sensor 30 monitor the state of the materials in real time. After the data is transmitted to the PLC programmable controller 3, the rotation speed of the stepping motor 7 and the injection amount of additives are intelligently adjusted to achieve precise control. After mixing is completed, the slurry pump 5 outputs the fluid-solidified soil through the discharge pipe 6. The entire set of systems realizes the efficient mixing of materials with different particle sizes and intelligent control through the coordinated operation of multiple units, improving the uniformity and material properties of the fluid-solidified soil.

[0045] A method for using a production and mixing device for fluid-solidified soil includes the following steps:

[0046] S1: Turn on the power supply, start the PLC programmable controller 3, calibrate the sensors, set the corresponding preset values on the PLC programmable controller 3, pour the raw materials such as cement, clay and stone weighed according to the designed ratio into the feed bin 9, and at the same time prepare an appropriate amount of water or other additives for adding through the injection pipe 11;

[0047] S2: Start the device. The stepping motor 7 runs on the frame 8, driving the main rotating shaft 21 to rotate. The main rotating shaft 21 drives the U-shaped stirring paddle 13 to preliminarily stir the materials entering the mixing tank 10. At the same time, the internal telescopic rod 39 realizes expansion and contraction through the centrifugal force of the counterweight ring 42. When it is at high speed, the mixing and stirring blades 37 extend to crush large-sized stones, and when it is at low speed, they retract to finely mix the cement and clay. The compression spring 31 and the tension spring 35 cooperate to buffer the load and assist in resetting. The sealing unit prevents the intrusion of materials into the driving inner cavity 38 through the conical sealing sleeve and the stainless steel ring 49. The double-tooth meshing rotary cover 12 drives the third transmission gear 20, driving the auxiliary rotating shaft 4 and the stirring auxiliary blades 14 to rotate. The scraper 54 and the rubber scraper strip 55 synchronously clean the materials on the tank wall to avoid accumulation;

[0048] S3: Real-time monitor the data of the materials in the tank through the humidity sensor 28, the pressure sensor 29 and the particle size sensor 30. After transmitting the data to the PLC programmable controller 3, automatically adjust the motor speed and the additive flow rate of the injection pipe 11 to achieve precise stirring. After completion, the slurry pump 5 outputs the fluidized solidified soil through the discharge pipe 6. The whole process realizes the efficient mixing and intelligent control of materials with different particle sizes through the cooperation of multiple units, improving the material uniformity and performance.
