Description

Technical Field

[0001] This utility model relates to the field of red mud-based solid waste cementitious material production technology, and in particular to a red mud-based solid waste cementitious material processing device. Background Technology

[0002] Red mud-based solid waste cementitious material (hereinafter referred to as "red mud cement") is prepared by mixing red mud discharged from alumina production with industrial solid wastes such as fly ash, steel slag, carbide slag, and desulfurization gypsum, and through high-alkali-calcium synergistic activation. During the raw material mixing process, the slurry is rich in OH... - Cl - SO4 2- Corrosive ions can cause severe corrosion to metal parts; secondly, the high content of hard particles in the slurry can cause serious wear on contact parts such as the agitator blades; finally, the initial setting time of red mud adhesive is 15-40 minutes, and the final setting time is 30-90 minutes, with a local temperature rise of up to 60 ℃, which easily leads to crusting and solidification on the surface of the agitator blades. When the raw material formula is changed on the production line, the mixing chamber needs to be cleaned in time and damaged blades need to be replaced to avoid cross-contamination between different batches of products. Since the agitator blades and the shaft of traditional mixing equipment are connected by welding, blade replacement requires a series of processes including shutdown, disassembly, and reinstallation, which is not only time-consuming and labor-intensive, but also increases the risk of production interruption. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a processing device for red mud-based solid waste cementitious materials, specifically employing the following technical solution: The red mud-based solid waste cementitious material processing device of this utility model includes a base frame, on which a stirring mechanism is mounted. The stirring mechanism includes a shell, a motor, stirring rods, mounting rods, mounting blocks, and stirring blades. The shell is connected to the base frame on both sides via auxiliary mechanisms. The motor is mounted on one side of the shell. The stirring rods are rotatably mounted inside the shell and connected to the motor output end. Multiple mounting rods are provided and fixedly connected to the stirring rods. The mounting blocks are U-shaped structural components corresponding to the ends of each mounting rod. The stirring blades are inserted into the middle of the mounting blocks and connected together by a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a snap-fit ​​sleeve, a snap-fit ​​rod, a movable groove, a push rod, a snap-fit ​​block, a snap-fit ​​groove, and a connecting plate. The snap-fit ​​sleeve is provided with... The mounting block is positioned on one side. The slot is located at the top of the inner cavity of the snap-fit ​​sleeve. The movable slot is a radial slot evenly distributed on the side wall of the snap-fit ​​sleeve. The push rod is slidably installed in each movable slot and is correspondingly set with each positioning hole of the slot. The snap block is located at the inner end of the push rod. Each snap block has a locking groove on its bottom surface. Each movable slot has a tension spring that passes through the push rod. The inner end of the tension spring is connected to the snap block. The connecting plate is located at the bottom of the side wall of the snap-fit ​​sleeve below the movable slot. The snap-fit ​​rod is correspondingly located on the other side of the mounting block and inserted into the snap-fit ​​sleeve. The top of the snap-fit ​​rod is provided with a locking sleeve located between the slot and the snap-fit ​​sleeve. The top of the locking sleeve is provided with locking tongues that are adapted to the locking groove at even intervals.

[0004] In this invention, the outer shell of the stirring mechanism is connected to the base frame via an auxiliary mechanism, facilitating shell tilting for quick material pouring and cleaning. The stirring blades are connected to the stirring rod via a snap-fit ​​mechanism. This snap-fit ​​mechanism connects the stirring blades and the mounting block together, and locks the stirring blades in place through cooperation with the snap-fit ​​sleeve. To disassemble the stirring blades, simply rotate the snap-fit ​​sleeve, causing the locking sleeve at the top of the snap-fit ​​rod to separate from the locking groove at the bottom of the push rod. The push rod then automatically retracts under the action of a tension spring, releasing the locking sleeve and snap-fit ​​rod. Removing the snap-fit ​​rod completes the blade disassembly. This snap-fit ​​mechanism securely locks the stirring blades and allows for quick and easy disassembly when replacement is needed. The entire process is time-saving and labor-saving, effectively preventing damaged blades from operating while damaged, and avoiding cross-contamination between different batches of products, thus ensuring smooth production.

[0005] Preferably, an anti-slip sleeve is fixedly provided on the outer side of the snap-fit ​​sleeve. This invention, by providing an anti-slip sleeve on the snap-fit ​​sleeve, can prevent the snap-fit ​​sleeve from slipping and failing to rotate properly, reducing operational errors and improving operational accuracy.

[0006] Preferably, a positioning mechanism is provided between the side walls of the locking rod and the locking sleeve. The positioning mechanism includes a positioning groove and a positioning block. The positioning groove is disposed on the outer wall of the locking rod, and the positioning block is disposed on the locking sleeve. By providing a positioning mechanism between the locking rod and the locking sleeve, this utility model can ensure precise locking between the locking sleeve and the locking groove when the locking sleeve rotates, thereby improving the connection reliability of the stirring fan blade.

[0007] Preferably, the positioning block is a positioning bead connected to the snap-fit ​​sleeve via a compression spring. This invention uses a positioning bead with a compression spring as the positioning block, enabling the snap-fit ​​rod and snap-fit ​​sleeve to achieve automatic positioning, improving positioning speed, and reducing human error.

[0008] Preferably, the auxiliary mechanism includes a mounting base, a support frame, hinge rods, and a hydraulic cylinder. The mounting base is mounted on a base frame, the support frame is mounted on the outer casing, and two hinge rods are provided. The two ends of each hinge rod are connected to the mounting base and the support frame, respectively. The cylinder body of the hydraulic cylinder is rotatably mounted on the base frame, and the piston rod of the hydraulic cylinder is rotatably connected to one of the hinge rods. When the hydraulic cylinder is working, it can drive the two hinge rods to swing, thereby tilting the outer casing, facilitating material unloading and internal cavity cleaning, and preventing material buildup on the blades and cross-contamination between different materials.

[0009] Preferably, an alumina ceramic anti-corrosion and wear-resistant layer is provided on the inner wall of the outer shell and the outer walls of the stirring rod, mounting rod, mounting block, stirring blades, and snap-fit ​​mechanism. This invention improves the corrosion and wear resistance of each component by providing an anti-corrosion and wear-resistant layer on the surface of parts that come into direct contact with materials. Furthermore, with timely cleaning, it effectively prevents the formation of a crust on the surface of the stirring blades.

[0010] The red mud-based solid waste cementitious material processing device provided by this utility model has an ingenious structure and is easy to use. The precise locking of the locking sleeve and locking groove can achieve a firm lock on the stirring fan blade. The stirring fan blade can be quickly disassembled by simply rotating the snap-fit ​​sleeve, which facilitates operations such as fan blade replacement and is conducive to the smooth progress of production.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Beneficial effects of the stirring mechanism: The stirring mechanism achieves efficient mixing of materials by driving the stirring rod to rotate through the motor. The power of the motor is transmitted to multiple sets of mounting rods through the stirring rod. The mounting blocks at the ends of the mounting rods drive the stirring blades to perform all-round stirring. This multi-point stirring design significantly improves the uniformity of mixing. The outer shell not only protects the internal structure but also prevents material splashing, improving operational safety. The design of multiple sets of stirring blades increases the contact area of ​​the stirring, improves the stirring efficiency, and also adapts to the needs of materials with different viscosities.

[0012] 2. Beneficial effects of the auxiliary mechanism: The auxiliary mechanism, through the cooperation of hydraulic cylinders and hinged rods, realizes the height adjustment of the mixing mechanism. The mounting base and support frame are fixed on the base frame and the outer shell respectively, providing stable support for the entire mechanism. The design of multiple sets of hinged rods ensures the smoothness of the lifting process. The use of hydraulic cylinders makes height adjustment simple and quick, without the need for manual operation. This design greatly increases the adaptability of the device, enabling it to adapt to containers or workbenches of different heights, thus improving the versatility and work efficiency of the equipment.

[0013] 3. Beneficial Effects of the Snap-fit ​​and Positioning Mechanisms: The snap-fit ​​mechanism, through the ingenious cooperation of the snap-fit ​​sleeve, snap-fit ​​rod, movable groove, push rod, snap-fit ​​block, and snap-fit ​​slot, enables the rapid installation and disassembly of the agitator blades. The design of the connecting plate makes operation simple and intuitive; locking or unlocking can be completed with a gentle rotation. The tension spring allows the snap-fit ​​block to automatically return to its original position, simplifying the operation process. The design of the locking sleeve and locking slot further increases the reliability of locking and prevents accidental unlocking. The cooperation of the positioning slot and positioning block in the positioning mechanism ensures the accuracy of each installation. The use of the compression spring automates the positioning process, reducing human error. The design of multiple positioning slots allows for precise positioning at multiple angles, increasing the flexibility of adjustment. This design not only greatly shortens the agitator blade replacement time and improves production efficiency but also improves the consistency of the agitation effect, ensuring the stability of product quality.

[0019] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0020] like Figure 1-5As shown, the red mud-based solid waste cementitious material processing device of this utility model includes a base frame 1, on which a stirring mechanism is installed. The stirring mechanism includes a shell 2, a motor 3, a stirring rod 4, mounting rods 5, mounting blocks 6, and stirring blades 7. The shell 2 is connected to the base frame 1 on both sides through auxiliary mechanisms. The motor 3 is installed on one side of the shell 2, and the output end of the motor 3 is connected to the stirring rod 4 located inside the shell 2, causing the stirring rod 4 to rotate under the action of the motor 3. Multiple mounting rods 5 are welded to the stirring rod 4, and a U-shaped mounting block 6 is welded to the end of each mounting rod 5. The stirring blades 7 are inserted into the middle of the mounting blocks 6 and connected together by a snap-fit ​​mechanism.

[0021] The aforementioned snap-fit ​​mechanism includes a snap-fit ​​sleeve 8, a snap-fit ​​rod 9, a movable groove 10, a push rod 11, a snap block 12, a snap groove 13, and a connecting plate 14. The snap-fit ​​sleeve 8 is an axisymmetric cavity structure with an opening facing downwards. The snap groove 13 is fixedly installed at the top of the inner cavity of the snap-fit ​​sleeve 8. Multiple positioning holes are evenly provided on the side wall of the snap groove 13. Each positioning hole corresponds to a radial movable groove 10 provided on the side wall of the snap-fit ​​sleeve 8. A push rod 11 is inserted into each movable groove 10. A tension spring 17 is sleeved on the push rod 11. The outer end of the tension spring 17 is fixedly connected to the side wall of the snap groove 13, and the inner end of the tension spring 17 is fixedly connected to the snap block 12 at the end of the push rod 11. A locking groove 15 is provided on the bottom surface of each snap block 12. Without external force intervention, the push rod 11 extends its tail out of the movable groove 10 under the action of the tension spring 17, and the snap block 12 connected to the push rod 11 is located inside the movable groove 10. The bottom of the aforementioned snap-fit ​​sleeve 8 is connected to the annular connecting plate 14. When the snap-fit ​​mechanism connects to the stirring fan blade 7, the connecting plate 14 is attached to one side of the mounting block 6. The snap-fit ​​rod 9 also adopts an axisymmetric structure, with a locking sleeve 16 at its top and a locking plate at its bottom. When the snap-fit ​​rod 9 is inserted into the snap-fit ​​sleeve 8 from the other side of the mounting block 6 and locked in place, the locking plate is attached to the mounting block 6. The aforementioned locking sleeve 16 is an annular structure coaxially arranged with the push rod 11. Its top is evenly spaced with locking tongues that are compatible with the locking groove 15, and the locking sleeve 16 is located between the locking groove 13 and the snap-fit ​​sleeve 8. Furthermore, an anti-slip sleeve 18 is installed on the outside of the snap-fit ​​sleeve 8. The bottom surface of the anti-slip sleeve 18 is in contact with the top surface of the connecting plate 14. It can improve the gripping difficulty caused by insufficient friction in humid or oily environments and improve the operator's control accuracy for rotating the snap-fit ​​sleeve 8. Furthermore, a positioning mechanism is provided between the side walls of the locking rod 9 and the locking sleeve 8. This positioning mechanism includes a positioning block 19 and a positioning groove 20. The positioning groove 20 is located on the outer wall of the locking rod 9, and the positioning block 19 is a positioning bead connected to the locking sleeve 8 by a compression spring. Multiple sets of the above-mentioned positioning mechanism are evenly arranged along the circumference of the locking rod 9. During the rotation of the locking sleeve 8, once the positioning groove 20 and the positioning block 19 are paired and matched, the locking groove 15 rotates to the position where it engages with the locking tongue.

[0022] When installing the agitator blade 7, first insert the agitator blade 7 into the middle of the mounting block 6, ensuring that the mounting holes on the agitator blade 7 and the mounting block 6 are aligned. Then, place the snap-fit ​​rod 9 on one side of the mounting block 6 and insert it into the mounting hole. Simultaneously, remove the snap-fit ​​sleeve 8 and press down all the push rods 11. Under pressure, the snap-fit ​​block 12 at the head of the push rod 11 moves towards the center of the snap-fit ​​sleeve 8 and enters the positioning hole of the snap-fit ​​groove 13. At this time, the tension spring 17 is in a stretched state. Next, align the center hole of the connecting plate 14 with the mounting hole of the mounting block 6 and attach it, so that the snap-fit ​​rod 9 is inserted into the inner cavity of the snap-fit ​​sleeve 8. Subsequently, rotate the locking sleeve 8. When the positioning block 19 on the locking sleeve 8 corresponds to the positioning groove 20 on the locking rod 9 and they are paired and matched, the push rod 11 inside the locking sleeve 8 drives the locking block 12 to rotate just above the locking tongue of the locking sleeve 16 at the top of the locking rod 9, so that the locking tongue corresponds to the locking groove 15 of the locking block 12. At this time, release the finger pressing the push rod 11. Under the action of the tension spring 17, the push rod 11 moves outward along the movable groove 10, so that the locking groove 15 is firmly locked on the locking tongue of the locking sleeve 16, making the locking rod 9 and the locking sleeve 8 firmly connected, thereby completing the installation of the stirring fan blade 7. When disassembling the stirring fan blade 7, simply press the push rod 11 and rotate the locking sleeve 8 to release the double lock between the locking rod 9 and the locking sleeve 8, and the locking rod 9 can be pulled out from the mounting block 6, thereby removing the stirring fan blade 7.

[0023] The auxiliary mechanism for connecting the outer shell 2 and the base frame 1 in this utility model includes a mounting base 22, a support frame 23, a hinge rod 24, and a hydraulic cylinder 25, such as... Figure 5 As shown, the mounting base 22 is mounted on the base frame 1, and the support frame 23 is mounted on the outer shell 2. The mounting base 22 and the support frame 23 are connected by two hinge rods 24. Specifically, both the support frame 23 and the mounting base 22 are square structures, and the mounting base 22 is relatively small. The vertical center lines of the mounting base 22 and the support frame 23 coincide. The two hinge rods 24 are at the same height, with the inner end of each hinge rod 24 connected to the mounting base 22 and the outer end connected to the support frame 23. Furthermore, the cylinder body of the hydraulic cylinder 25 is rotatably mounted on the base frame 1, and the piston rod of the hydraulic cylinder 25 is rotatably connected to the middle of the hinge rod 24 near the rear side of the outer shell 2. When the piston rod of the hydraulic cylinder 25 extends, the hinge rod 24 connected to it causes the rear side of the outer shell 2 to rise, while the front hinge rod 24 causes the front side of the outer shell 2 to descend, thus tilting the outer shell 2 for material unloading. Furthermore, if the formula needs to be changed, the inner cavity of the outer shell 2 and its related components can be rinsed with water first. Then, the auxiliary mechanism can be activated to pour the cleaning water out of the outer shell 2 to avoid cross-contamination between different materials.

[0024] Furthermore, an alumina ceramic anti-corrosion and wear-resistant layer is provided on the inner wall of the outer casing 2 and on the outer walls of the stirring rod 4, mounting rod 5, mounting block 6, stirring blade 7, and snap-fit ​​mechanism. This invention improves the corrosion and wear resistance of each component by providing an anti-corrosion and wear-resistant layer on the surface of parts that come into direct contact with materials. Simultaneously, with timely cleaning, it effectively prevents the formation of a crust on the surface of the stirring blade.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
