Abstract
Description
Technical Field
[0001] This utility model relates to the field of cementitious materials technology, and more specifically, to a fully automatic cementitious material preparation device. Background Technology
[0002] In modern infrastructure construction fields such as architecture, water conservancy, and transportation, cementitious materials, as a core component of composite materials such as concrete and mortar, directly determine the strength, durability, and stability of engineering structures. With the acceleration of global urbanization, the market demand for cementitious materials continues to grow. At the same time, the research and application of high-performance concrete and special engineering materials have placed higher demands on the precise and standardized production of cementitious materials, highlighting the limitations of traditional preparation technologies.
[0003] Traditional cementitious material preparation processes rely on manual operation, which has significant drawbacks from raw material proportioning and weighing to mixing. Manual batching is not only inefficient and unsuitable for large-scale continuous production, but also prone to batch-to-batch quality fluctuations due to human error, failing to meet the stringent requirements for material performance consistency in engineering projects. For example, in major projects such as bridges and nuclear power plants, even minor performance differences in cementitious materials can pose structural safety hazards. Furthermore, traditional equipment often employs intermittent production modes, resulting in long material mixing cycles and frequent equipment start-ups and shutdowns, leading to energy waste and capacity limitations.
[0004] Therefore, there is an urgent need for a technology to replace the existing methods of preparing cementitious materials in order to solve the problems of reducing material mixing cycles, frequent equipment start-ups and shutdowns, and resulting energy waste and capacity limitations.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] See Figure 1 and Figure 2 As shown, this embodiment provides a fully automatic cementitious material preparation device, including a frame 100, a mixing chamber 600, and a tilting mechanism 700.
[0034] Specifically, the frame 100 includes a mixing chamber 600 located inside the frame 100. The mixing chamber 600 has a mixing cavity, inside which is a mixing body 630. Asymmetrical turbine blades 632 are provided on the side of the mixing body 630. A first driven gear 631 is provided at the end of the mixing body 630 that extends from the top of the mixing cavity to the outside of the mixing chamber 600. A motor box 640 is provided on the upper surface of the mixing chamber 600. A first drive motor 641 is provided inside the motor box 640. A first driving gear 642 is provided at the output end of the first drive motor 641. The first driving gear 642 corresponds to the driven gear. A tilting mechanism 700 consists of two sets of tilting components symmetrically arranged on the outer side of the mixing chamber 600. The tilting mechanism 700 is used to adjust the tilt angle of the mixing chamber 600.
[0035] Specifically, the inner wall of the mixing chamber 600 is sprayed with a superhydrophobic and wear-resistant coating.
[0036] It is understood that the unique asymmetric turbine blades 632 in the above embodiment, combined with the first drive motor 641 and gear transmission structure, enable the agitator 630 to achieve high-speed and asymmetric mixing motion within the mixing chamber. Compared to traditional symmetrical blades, the asymmetric design breaks the material flow inertia, generates a more complex vortex field, effectively eliminates mixing blind spots, improves the uniformity of cementitious material mixing, significantly shortens mixing time, and meets the dual requirements of efficiency and quality for large-scale production.
[0037] Two sets of symmetrical tilting components can precisely adjust the tilt angle of the mixing chamber to 600 degrees. During unloading, the tilting action allows the material to slide down quickly under gravity, avoiding residue accumulation, improving unloading efficiency, and reducing the frequency of manual cleaning. In addition, the tilted state allows for all-round flushing of the mixing chamber, more thoroughly cleaning residual material in dead corners, ensuring the purity of materials produced in different batches, and reducing the risk of performance fluctuations between batches.
[0038] The integrated layout of the frame 100 support and motor box 640 makes the equipment structure compact and stable, reducing vibration and noise during operation; the gear transmission system has good sealing performance, reducing dust leakage and mechanical wear, and extending the service life of the equipment; the linkage control between the tilting mechanism 700 and the stirring system can be automated through PLC, avoiding safety hazards caused by manual intervention, while supporting rapid switching of process parameters in multiple scenarios, significantly improving production flexibility and intelligence level.
[0039] See Figure 3 As shown, a baffle is provided at the bottom of the mixing chamber, and the baffle has several discharge holes arranged in a ring. The baffle has a through hole at the center of the ring. A first corrugated pipe 530 is connected to the bottom of the mixing chamber 600, and a discharge valve 620 is provided between the first corrugated pipe 530 and the baffle.
[0040] Specifically, a rotating base 660 is provided on the upper surface of the partition, and a support column 662 and a discharge blocking rod 661 are provided on the lower surface of the rotating base 660. The positions of the support column 662 and the discharge blocking rod 661 correspond to the through hole and several discharge holes, respectively. The support column 662 and the discharge blocking rod 661 are slidably connected to the through hole and several discharge holes, respectively. The bottom end of the support column 662 passes through the through hole to the bottom of the partition. A limit block 663 is provided at the bottom end of the support column 662. The radius of the limit block 663 is smaller than the minimum radius of the circle formed by the discharge holes. A return spring 670 is sleeved on the outer side of the support column 662 above the partition.
[0041] Specifically, the upper surface of the rotating base 660 is rotatably connected to the bottom end of the stirring body 630, and the stirring body 630 is movably connected to the top of the stirring chamber.
[0042] See Figure 4 As shown, a hydraulic mechanism 110 is provided on the lower surface of the top plate of the frame 100. The hydraulic mechanism 110 is provided with a hydraulic rod. The position of the hydraulic rod corresponds to the position of the stirring body 630. The hydraulic mechanism 110 is used to change the horizontal position of the stirring body 630 and the rotating base 660 until the first driven gear 631 and the first driving gear 642 are on the same horizontal line.
[0043] The specific working process of the above embodiment is as follows: Before the device is started, the discharge valve 620 is in the closed state. At this time, the return spring 670 is in the naturally extended state, pushing the support column 662 upward, causing the discharge blocking rod 661 to tightly leave the discharge hole; the limit block 663 is stuck under the partition plate to ensure that the support column 662 will not disengage from the through hole, maintaining structural stability. The rotating base 660 is rotatably connected to the bottom end of the stirring body 630, the first driven gear 631 and the first driving gear 642 are in a misaligned state, and the equipment is in the standby preparation stage.
[0044] Hydraulic mechanism 110 is activated, and the hydraulic rod pushes the mixing body 630 and the rotating base 660 horizontally, causing the first driven gear 631 to precisely mesh with the first driving gear 642. The discharge blocking rod 661 is embedded in the discharge hole, achieving a seal on the mixing chamber 600. The first drive motor 641 operates, driving the first driven gear 631 through the first driving gear 642, thereby driving the mixing body 630 to rotate at high speed. The asymmetric turbine blades 632 agitate the cementitious material in the mixing chamber, forming complex vortices to achieve uniform mixing of the material. During this process, the support column 662 and the discharge blocking rod 661 remain fixed, maintaining a seal on the discharge hole and through hole, ensuring that the material is fully mixed in the mixing chamber without leakage.
[0045] After the material is mixed, the hydraulic mechanism 110 reverses the hydraulic rod, lifting the mixing body 630 and the rotating base 660 upwards, separating the first driven gear 631 and the first driving gear 642, and stopping the transmission of mixing power. Simultaneously, the discharge valve 620 is opened. The rotating base 660 continues to rise under the influence of the hydraulic mechanism 110. The support column 662 is blocked by the partition, the rotating base 660 stops sliding, the return spring 670 returns to its extended state, and the discharge blocking rod 661 gradually withdraws from the discharge hole. The annularly distributed discharge holes open, and the material, under gravity, disperses through the discharge holes and falls into the first bellows 530, then is discharged through the discharge channel. Because the radius of the limiting block 663 is smaller than the minimum radius of the circle formed by the discharge holes, it ensures that the support column 662 does not obstruct the material from being discharged through the through hole during its downward movement, achieving rapid and residue-free discharge.
[0046] Understandably, this device achieves efficient linkage and precise control of the mixing and unloading processes through a multi-structure collaborative design. The annularly distributed unloading holes and through-holes, combined with the unloading blocking rod 661, prevent material leakage during mixing and allow for rapid unloading with no residue. The return spring 670 and limit block 663 ensure stable sliding of the support column 662, guaranteeing reliable operation of the unloading structure. The hydraulic mechanism 110 drives the mixing body 630 to move horizontally, achieving precise gear meshing and power switching, reducing idling energy consumption. The rotating base 660 integrates the mixing and unloading components, making the equipment operate compactly and orderly, significantly improving the efficiency and quality stability of cementitious material preparation, and reducing the frequency of manual intervention and maintenance costs.
[0047] See Figure 5As shown, the inclined assembly is provided with a fixing plate 710, which is fixedly connected to the outer side of the mixing chamber 600. A fixing rod 720 is provided on the surface of the fixing plate 710. A second driven gear 730 is provided at the end of the fixing rod 720 away from the mixing chamber 600. A first transmission bar 740 and a second transmission bar 750 are respectively provided on the upper and lower sides of the second driven gear 730. Both the first transmission bar 740 and the second transmission bar 750 are provided with racks 741 that mesh with the second driven gear 730. The first transmission bar 740 and the second transmission bar 750 pass through both sides of the frame 100 and are slidably connected to the frame 100.
[0048] Specifically, the frame 100 is provided with a second drive motor 760 on each of its two sides, and a second drive gear 770 is provided at the output end on each side of the second drive motor 760. The second drive gear 770 meshes with the rack 741 of the first transmission bar 740 and the second transmission bar 750 respectively.
[0049] Specifically, when the angle of the mixing chamber 600 needs to be adjusted in the above embodiment, the second drive motors 760 on both sides of the frame 100 start synchronously, and the second drive gear 770 at the output end begins to rotate. Since the second drive gear 770 meshes with the rack 741 of the first transmission bar 740 and the second transmission bar 750, the motor torque is converted into linear driving force, pushing the two transmission bars to slide along the frame 100.
[0050] Specifically, if the two second drive motors 760 rotate in the same direction, the first transmission bar 740 and the second transmission bar 750 will move synchronously and in the same direction, driving the fixed rod 720 and the fixed plate 710 to move as a whole, thereby achieving a fine-tuning of the horizontal position of the mixing chamber 600. When the two motors rotate in opposite directions, the first transmission bar 740 and the second transmission bar 750 move towards or away from each other, causing the second driven gear 730 to rotate. This rotation, through the fixed rod 720, drives the fixed plate 710 to rotate around the fulcrum, thereby achieving a tilting action of the mixing chamber 600.
[0051] Understandably, this tilting assembly employs an innovative structure with dual-drive double racks 741 and gear meshing. A second drive motor 760 drives a second active gear 770 to drive the first and second transmission bars 750. The precise and stable adjustment of the angle of the mixing chamber 600 is achieved through the cooperation of the racks 741 and the second driven gear 730. Compared to traditional single-drive or linkage-type tilting mechanisms 700, the symmetrical drive of the double racks 741 ensures uniform force distribution on the mixing chamber 600, preventing swaying or jamming during tilting. The angle control accuracy reaches ±0.5°, and stepless adjustment within the range of 0-90° is possible. Simultaneously, the self-locking characteristic of the racks 741 ensures stable fixation of the mixing chamber 600 at any angle, eliminating the need for additional locking devices. This improves unloading efficiency and material residue cleaning, while reducing equipment maintenance costs and failure risks, significantly enhancing the practicality and reliability of the cementitious material preparation device.
[0052] Specifically, a constant temperature liquid storage component 610 is also provided on the outer side of the mixing chamber 600. The constant temperature liquid storage component 610 is provided with a constant temperature liquid storage tank 611. The constant temperature liquid storage tank 611 is annular and fixed to the outer side of the mixing chamber 600. Several water supply pipes 612 are provided on the upper surface of the constant temperature liquid storage tank 611. Each water supply pipe 612 passes through the outer wall of the mixing chamber 600 to the inside of the mixing chamber. A nozzle 613 is provided at the end of the water supply pipe inside the mixing chamber.
[0053] Specifically, several water supply pipes 612 are evenly distributed on the upper surface of the constant temperature storage tank 611, penetrating the outer wall of the mixing chamber 600 and extending into the mixing cavity. This multi-point layout ensures that the water glass solution can be quickly and evenly integrated into the material. The nozzles 613 at the end of the pipes are specially designed to use atomization or fan-shaped spray patterns, which can spray the water glass solution into the mixing cavity in the form of fine particles. Compared with the traditional direct injection method, this significantly increases the contact area between the water glass solution and the material, reduces the stirring time, and improves the mixing uniformity. For example, when preparing water glass cementitious materials, the precise addition of the curing agent aqueous solution through the nozzle 613 can make the reaction more complete and effectively avoid the problem of clumping caused by excessively high local concentrations.
[0054] Understandably, the annular constant-temperature storage tank 611 fits tightly against the mixing chamber 600, achieving 360° surround temperature control. This keeps the temperature fluctuation within the mixing chamber within ±1℃, effectively preventing abnormal coagulation of the cementitious material or chemical reaction imbalance caused by temperature changes. It is particularly suitable for the production of temperature-sensitive materials such as special cement and water glass. Several water supply pipes 612, in conjunction with the nozzles 613, can evenly spray the water glass solution additive into the mixing chamber in an atomized form. Compared with the traditional direct injection method, the material mixing efficiency is increased by more than 40%, ensuring full contact between the additive and the cementitious material and eliminating the problem of uneven local concentration. In addition, the integrated function of constant temperature and liquid supply simplifies the equipment structure and reduces space occupation. At the same time, through the linkage of the intelligent control system, precise control of temperature regulation and water glass solution addition is achieved, significantly improving the intelligence level and production stability of the preparation device, and reducing the defect rate and energy consumption.
[0055] Specifically, a tailings bin 200 and a slag bin 300 are installed on the top of the frame 100. A feeding pipe 400 is installed at the bottom of the tailings bin 200 and the slag bin 300. The amount of raw material fed is fed in real time through a weighing sensor. The feeding pipe 400 is L-shaped. A screw feeder 420 is installed inside the long pipe of the feeding pipe 400. A third drive motor 410 is installed at the end of the long pipe away from the bend. The output end of the third drive motor 410 is connected to the screw feeder 420. The short pipe of the feeding pipe 400 is a second corrugated pipe 430. The second corrugated pipe 430 passes through the top plate of the frame 100 and is connected to the feed inlet 650 on the upper surface of the mixing chamber 600.
[0056] Understandably, the L-shaped feeding pipe 400, in conjunction with the screw feeder 420, enables tailings and slag to form a stable spiral flow during transportation, preventing particle deposition and pipe blockage, thus improving transportation efficiency by more than 30%. The flexible connection design of the second corrugated pipe 430 can compensate for displacement changes during the tilting process of the mixing chamber 600, and also buffer material impact through its own elasticity, reducing pipe wear and extending service life by 50%. The screw feeder 420 is independently controlled by the third drive motor 410, which can precisely adjust the feeding speed according to the preparation process requirements, with a feeding accuracy of ±0.3%, ensuring the stability of the cementitious material formula. The independent setting of the tailings bin 200 and the slag bin 300 supports differentiated supply of multi-component materials, providing flexible configuration for the preparation of high-performance composite cementitious materials. The overall enclosed conveying structure effectively suppresses dust emission, reducing dust emissions by 85%, meeting environmental protection requirements while improving the working environment and realizing the green and efficient reuse of industrial waste.
[0057] Specifically, the bottom end of the first corrugated pipe 530 is connected to the conveying pipe 500. The conveying pipe 500 is equipped with a screw conveyor 510. A fourth drive motor 520 is provided at one end of the conveying pipe 500 near the first corrugated pipe 530. The output end of the fourth drive motor 520 is connected to the screw conveyor 510. A retainer 540 is provided at one end of the conveying pipe 500 away from the first corrugated pipe 530. Several fastening bolts 541 are provided on the side of the retainer 540.
[0058] Specifically, the 500 conveying pipeline is a fully enclosed stainless steel pipeline.
[0059] Understandably, driven by the fourth drive motor 520, the screw conveyor 510 can forcibly convey the material discharged from the first corrugated pipe 530. Compared with gravity flow, the conveying efficiency is increased by 40%, and the accumulation and blockage of materials in the pipe can be avoided. At the same time, the screw conveying process can perform secondary agitation on the material, further improving the mixing uniformity. The connection between the flexible first corrugated pipe 530 and the rigid conveying pipe 500 effectively mitigates the impact of unloading and reduces equipment vibration. The retainer 540 at the end of the conveying pipe 500, together with the fastening bolt 541, can achieve quick connection and disassembly with different types of receiving equipment (such as storage tanks and transport vehicles), which is highly versatile. By adjusting the fastening bolt 541, the installation angle and position of the conveying pipe 500 can also be flexibly adjusted to adapt to diverse production scenarios, significantly reduce equipment modification costs, enhance the practicality and expandability of the device, and provide reliable protection for the subsequent processing of cementitious materials.
