Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a rotary self-driven magnetized concrete mixing device. Background Technology

[0002] Concrete, as a core material in modern construction engineering, directly affects the durability, strength, and construction efficiency of structures. Traditional concrete preparation often relies on chemical admixtures or mineral additives to improve early strength and workability. However, these methods suffer from problems such as incomplete reactions, high energy consumption, rising costs, and environmental pollution. For example, admixtures can leave unreacted components, leading to unstable concrete performance in later stages; the activation of mineral additives requires high temperatures or strong acid / alkali conditions, making the process complex and imposing significant environmental pressures. Therefore, developing green and low-cost concrete modification technologies has become an urgent need for the industry.

[0003] Magnetized water technology alters the structure of water molecules through the action of a magnetic field, reducing surface tension and viscosity, and enhancing water molecule activity, providing a new approach to optimizing concrete performance. Studies have shown that magnetized water can accelerate cement hydration and refine pore structure, thereby significantly improving the compressive strength and durability of concrete. Compared to chemical methods, magnetized water technology requires no added substances, offering advantages such as environmental friendliness, energy efficiency, and low cost. However, existing magnetization devices still face several bottlenecks in engineering applications: firstly, traditional permanent magnet devices often employ a fixed magnetic field design, resulting in poor adaptability and difficulty in matching water supply pipelines of different diameters or materials, leading to fluctuations in magnetization efficiency; secondly, magnetized water is susceptible to demagnetization effects, with its activity decreasing over time and with environmental changes, making it difficult to maintain long-term stability.

[0004] In conclusion, developing a magnetization device with strong adaptability, adjustable magnetization parameters, and the ability to maintain water activity over a long period is crucial to overcoming the technological bottlenecks in concrete performance optimization and environmental remediation. There is an urgent need to achieve efficient preparation of magnetized concrete through innovative structural design and the integration of dynamic magnetic field control technology, thereby driving the concrete industry towards green and intelligent upgrades.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Example 1

[0050] like Figure 1 and Figure 2 As shown: This embodiment provides a rotary self-driven magnetized concrete mixing device, including: a base, a drum water tank assembly, a magnetization device, and a mixer 7.

[0051] Specifically, the drum water tank assembly, the magnetizing device, and the mixer 7 are all mounted on the base. The magnetizing device is symmetrically arranged on both sides of the drum water tank assembly, and the distance between the magnetizing device and the drum water tank assembly can be dynamically adjusted; the magnetizing device can magnetize the water in the drum water tank assembly; the drum water tank assembly can discharge the magnetized water into the mixer for mixing concrete materials.

[0052] This device is based on the synergistic effect of centrifugal force and a dynamic magnetic field. The centrifugal force generated by the rotation of the drum water tank causes the water to circulate, extending the residence time of water molecules in the magnetic field while avoiding external circulation systems. Magnetization causes some hydrogen bonds in water molecules to break, reducing surface tension and viscosity, increasing the contact area with cement particles, accelerating the hydration reaction, and optimizing the pore structure of concrete. Compared with existing technologies, this device, through its innovative structure, eliminates the need for an external circulation system, significantly simplifying the process flow, while also offering greater compatibility and controllable modification costs. Concrete prepared using this device exhibits significantly optimized overall performance, improving mechanical strength while reducing material consumption and enhancing durability, thus combining environmental benefits with engineering economics.

[0053] Specifically, the drum water tank assembly includes: a housing 2, a drum water tank 4, and a drive device; the housing 2 is disposed on the base; the drum water tank 4 and the drive device are both disposed within the housing 2. The rotating shaft of the drum water tank 4 is rotatably connected to the housing 2; the drive device is drivenly connected to the rotating shaft and can drive the drum water tank 4 to rotate within the housing 2 by driving the rotating shaft.

[0054] In this embodiment, the magnetizing device is fixedly installed on the outer wall of the housing 2; the magnetizing device can form a rectangular annular magnetic field region in the housing 2; the driving device drives the rotation direction of the drum water tank to be perpendicular to the magnetic field lines distribution.

[0055] It should be noted that the magnetization device includes four neodymium iron boron permanent magnets 1 and a hydraulic adjustment rod assembly 3. The four neodymium iron boron permanent magnets 1 are connected to the hydraulic adjustment rod assembly 3; the neodymium iron boron permanent magnets 1 are arranged in pairs, respectively on the left and right sides of the housing 2 by means of the hydraulic adjustment rod assembly 3. For example, the hydraulic adjustment rod assembly 3 includes a left hydraulic adjustment frame and a right hydraulic adjustment frame; the left and right hydraulic adjustment frames are symmetrically fixed on both sides of the housing; the left and right hydraulic adjustment frames have the same structure.

[0056] In practical applications, a set of neodymium iron boron permanent magnets 1 are arranged vertically in parallel on the left hydraulic adjustment frame; a set of neodymium iron boron permanent magnets 1 are arranged vertically in parallel on the right hydraulic adjustment frame. The distance between the two neodymium iron boron permanent magnets 1 in the left set and the housing 2 can be adjusted by the left hydraulic adjustment frame; the distance between the two neodymium iron boron permanent magnets 1 in the right set and the housing 2 can be adjusted by the right hydraulic adjustment frame.

[0057] In this embodiment, the drum water tank 4 is provided with an inlet 5 and an outlet 6; the inlet 5 is provided with a sealing cover that can be opened or closed; the outlet 6 is provided with a drain valve; the drain valve can be aligned with the drain pipe to discharge magnetized water into the drain pipe; the drain pipe is connected to the mixer and can discharge magnetized water into the mixer 7 for mixing and preparing concrete materials.

[0058] Accordingly, the mixer 7 is provided with a feed inlet; the mixer 7 is connected to a first control switch and a power supply; the drive device of the drum water tank assembly is connected to a second control switch and a power supply; the left hydraulic adjustment frame and the right hydraulic adjustment frame are both connected to a third control switch and a hydraulic pump power source.

[0059] In practice, according to the concrete mix requirements, a measured amount of mixing water is injected into the drum water tank 4 through the inlet 5. The drum water tank 4 is started to rotate at a preset speed, and the extension and retraction are adjusted by the hydraulic adjusting rod 3 to achieve the target distance between the neodymium iron boron permanent magnet 1 and the outer wall of the outer shell 2. During this process, the water is driven by centrifugal force to circulate closely against the inner wall of the drum water tank 4, prolonging its residence time in the magnetic field and ensuring uniform magnetization. After magnetization is completed, the outlet 6 is opened, and the magnetized water flows into the mixing chamber of the mixer 7 through the pipe. Cement, sand, and other materials are added through the feed inlet, and the mixer 7 is started to mix thoroughly.

[0060] Example 2

[0061] Device structure construction

[0062] like Figure 1 and Figure 2 As shown: First, place the base on a flat surface and use a level to check the levelness of the base surface. If the levelness deviation exceeds 3mm / m, adjust the height of the four support legs. During adjustment, first loosen the locking nuts at the bottom of the support legs, then use a wrench to rotate the adjusting screw, following the level indicator, until the base is level. After adjustment, tighten the locking nuts to ensure the support legs are securely fixed, and check that the anti-slip rubber pads are in close contact with the ground to prevent slippage during operation.

[0063] Install housing 2 onto the base, determining its installation position according to the design drawings, and secure it with high-strength bolts. During installation, ensure the bolts are tightened evenly, with the tightening torque of each bolt controlled at 80-100 N·m to ensure housing 2 is firmly installed and will not deform due to uneven stress. Before installing the drum water tank 4, clean the bearing mounting holes of housing 2 to remove impurities and oil. Then, install two high-precision 6310 deep groove ball bearings into the bearing mounting holes using a heat-fitting method, heating the bearings to 80-100℃ to expand their inner diameter, facilitating smooth installation onto the shaft. After installing the bearings, install double-lip rubber seals on the outside of the bearings, ensuring the sealing device is properly installed to prevent water and dust from entering the bearing area. Next, hoist the drum water tank 4 into housing 2 as a whole, ensuring accurate alignment between the drum water tank 4's shaft and the bearings. Adjust the position of the drum water tank 4 to ensure a uniform gap between it and housing 2, controlled at 2-3 mm. Fix the variable frequency motor in the predetermined position on the base. The motor installation should ensure that the parallelism error between its axis and the axis of the drum water tank's 4-spindle does not exceed 0.5mm. Connect the motor to the shaft via a belt drive mechanism. Select an A-type V-belt of appropriate length. After installing the belt, adjust its tension to prevent slippage during operation, while also avoiding excessive load on the bearings and motor due to over-tightness. Generally, applying vertical pressure to the middle of the belt, resulting in a belt deflection of 15-20mm, is recommended.

[0064] Install the left and right hydraulic adjustment brackets on both sides of the housing 2. First, fix the fixed brackets to the housing 2 with M12 bolts, tightening the bolts to a torque of 60-80 N·m. When installing the hydraulic cylinder, ensure that the installation direction of the hydraulic cylinder is correct, and that its axis is consistent with the movement direction of the neodymium iron boron permanent magnet 1. Connect one end of the telescopic rod to the piston of the hydraulic cylinder, and weld the other end to the corrosion-resistant neodymium iron boron permanent magnet. During the welding process, pay attention to controlling the welding temperature and time to prevent the permanent magnet from weakening due to overheating. After welding, check the firmness of the connection to ensure that it will not loosen during hydraulic adjustment.

[0065] Install the mixer 7 on the base. Based on the direction and length of the drain pipe, determine the appropriate installation position of the mixer to ensure a smooth connection between the drain pipe and the outlet 6 of the drum water tank 4 and the feed inlet of the mixer 7, while avoiding excessive bending or breakage of the drain pipe. Install two sets of spirally distributed mixing blades inside the mixing drum. During installation, ensure the angle and position of the blades are accurate, and control the gap between the blades and the inner wall of the mixing drum to 3-5mm to ensure effective mixing. Electrically connect the intelligent touchscreen controller to the mixer's motor, sensors, and other components. Strictly follow the electrical wiring diagram during connection to ensure correct and secure wiring, preventing short circuits and open circuits. After connection, check and test the electrical system to ensure the controller can properly control the mixer's operation.

[0066] Implementation process

[0067] Preparation: Conduct a comprehensive inspection of all connections of the device, ensuring all bolts are tight and secure; check the electrical wiring connections for correctness and the firmness of all terminals; use a multimeter to test the continuity of the circuit, ensuring there are no short circuits or open circuits; check the hydraulic system's pipe connections for tightness and leaks, inject an appropriate amount of hydraulic oil into the hydraulic system, start the hydraulic pump, and observe for oil seepage from the hydraulic pipes and joints. Open the inlet seal and inject 1000 liters of mixing water into the drum tank through the inlet pipe. Observe the water level changes during the filling process. When the water level reaches the predetermined height, close the inlet valve and then close the inlet seal to ensure a good seal and prevent water leakage in subsequent processes.

[0068] Initiating the magnetization process: Start the drive unit of the drum water tank assembly via the second control switch. Set the rotation speed of the drum water tank 4 to 120 rpm on the control panel of the variable frequency motor. After the motor starts, observe the operation of the drum water tank 4 to ensure smooth rotation without abnormal vibration or noise. Control the left and right hydraulic adjustment frames via the third control switch. Adjust the extension and retraction of the hydraulic cylinders according to the preset magnetic field strength and range of action, adjusting the distance between the neodymium iron boron permanent magnet 1 and the outer wall of the outer shell 2 to 4 cm, so that the four neodymium iron boron permanent magnets 1 form a stable rectangular annular magnetic field area around the shell 2. During the adjustment process, use a magnetic field strength detector to monitor the magnetic field strength in real time to ensure that the magnetic field strength meets the requirements. The water flows tightly against the inner wall of the drum water tank 4 under the action of centrifugal force, continuously magnetizing in the magnetic field for 12 minutes. During the magnetization process, regularly observe the state of the water flow and the changes in the magnetic field strength, and make timely adjustments if any abnormalities are found.

[0069] Discharging magnetized water: After magnetization is complete, remotely open the electric butterfly valve at the outlet via the control system to observe the discharge of magnetized water and ensure smooth drainage. During the discharge process, carefully check the connection between the drain pipe and the feed inlet of mixer 7 for leaks; if any leaks are found, address them promptly. Once the magnetized water in drum water tank 4 has been completely discharged, close the electric butterfly valve.

[0070] Add materials and mix: Add 500 kg of cement and 1200 kg of sand and gravel sequentially into mixer 7 through the feed inlet. Control the adding speed to prevent material accumulation at the feed inlet. After adding, set the mixing speed to 180 rpm and the mixing time to 6 minutes on the intelligent touchscreen controller. After setting, turn on the first control switch of the mixer, and mixer 7 will begin to thoroughly mix the materials. During the mixing process, observe the operation of mixer 7 to ensure the mixing blades operate normally without abnormal noise or vibration. After mixing is complete, turn off the mixer, open the discharge door of mixer 7, and discharge the prepared concrete for subsequent construction.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
