[0014] A green geopolymer cement production and processing feeding method, comprising the following steps: Step one: the driving mechanism is the core of feeding switching and sealing. After the hydraulic rod is started, the central table is vertically lifted, and the outer side plate is synchronously moved; the two sides of the first spring are deformed with the lifting of the side plate, buffer impact and auxiliary reset, and the elastic expansion rod at the bottom of the central table drives the first block and the second block to move synchronously, laying a foundation for the subsequent feeding mechanism triggering; Step two: the driving mechanism triggers the second feeding mechanism, that is, when the side plate moves downward, the side plate hole limits the first jacking rod, and the second jacking rod is not limited. The second electric push rod is started, the second multi-fold rod is slid, and the rotating plate is rotated; the device moves above the stirring equipment, the external magnet attracts the sealing plate magnet block, the sealing plate is deflected to discharge, and after the end, the device is reset, and the elastic strip drives the sealing plate to reset; Step three: the driving mechanism triggers the first feeding mechanism, that is, when the side plate moves upward, the side plate hole limits the second jacking rod, and the first jacking rod is not limited. The first electric push rod is started, the first multi-fold rod is slid, the trapezoidal block is inserted into the first feeding cylinder, and the column is extruded to slide downward to discharge; after the end, the electric push rod is retracted, the second spring drives the column to reset, and the notch and the discharge channel are dislocated to realize sealing; Step four: the sealing mechanism is linked with the double feeding mechanism to strengthen the bottom sealing. When the first feeding mechanism is not working, the associated force makes the first reset expansion plate unfold and adhere to the bottom; when the second feeding mechanism is not working, the second reset expansion plate unfolds and adheres to the bottom. When the second feeding mechanism is working, the sealing mechanism reversely strengthens the sealing of the first feeding cylinder to avoid leakage of raw materials.

[0015] Compared with the prior art, the green geopolymer cement production and processing feeding device has the following beneficial effects: 1. The double feeding mechanism can be flexibly switched to adapt to the conveying requirements of multiple types of raw materials. The device is equipped with the second feeding mechanism suitable for liquid sodium silicate solution and the first feeding mechanism suitable for solid-liquid mixed slag slurry. The driving mechanism controls the lifting of the hydraulic rod to realize the quick switching of the two mechanisms. Without the need to replace equipment or make complex adjustments, the conveying requirements of raw materials in different forms such as liquid and solid-liquid mixture can be met, which greatly improves the adaptability of the equipment to diversified production scenes and reduces the cost of multiple equipment investment.

[0016] 2. The synchronous sealing design eliminates the risk of raw material leakage. No matter which feeding mechanism is working, the sealing mechanism can simultaneously strengthen the sealing of the non-working mechanism. That is, the reset expansion plate is unfolded by driving the change of air pressure, tightly adheres to the bottom of the non-working feeding cylinder, and cooperates with the sealing structure of the feeding cylinder to form double protection. This effectively avoids the leakage of liquid raw materials or the overflow of solid-liquid mixed slurry, not only ensures the cleanliness of the production environment, but also reduces raw material waste and the risk of equipment failure caused by leakage.

[0017] 3. Stable operation and convenient operation improve the feeding efficiency. The driving mechanism buffers the lifting impact through springs, elastic expansion rods and other components to ensure the stability of the switching and operation process of the feeding mechanism. During the feeding stage, the electric push rod drives the multi-fold rod, trapezoidal block and other components to cooperate and move to realize accurate conveying of raw materials. The wedge-shaped structure of the trapezoidal block can prevent particles in the solid-liquid slurry from being stuck, ensuring smooth conveying. The entire operation can be completed by controlling the hydraulic rod and electric push rod without complex manual intervention, which greatly improves the feeding efficiency and adapts to continuous production requirements.

[0018] 4. Mechanism reset automation ensures the smooth connection of continuous operation: after the feeding is completed, the hydraulic rod retraction can automatically reset the center table, and the springs, elastic strips and other components can simultaneously drive the sealing plate, column and reset expansion plate to return to the initial state, preparing for the next feeding switching or operation. Without manual adjustment, the operation steps and waiting time are reduced, ensuring the smooth connection of different raw material conveying operations and further improving the continuity and efficiency of the overall production process.

[0039] When the liquid sodium silicate solution needs to be delivered, i.e. the second feeding mechanism 3 is adapted to the liquid raw material, the hydraulic rod 12 starts to push the center platform 13 to move downward, the surrounding plate 14 moves downward synchronously, the two sides of the first spring 16 are stretched, and the buffer lifting impact is buffered; the elastic telescopic rod 19 at the bottom of the center platform 13 drives the first block 10 and the second block 101 to move downward, the surrounding plate 14 surface hole covers the first ejector rod 24 of the first feeding mechanism 2 and limits it, so as to ensure that it does not act. At the same time, the second electric push rod 33 of the second feeding mechanism 3 starts to push the second multi-fold rod 34 to slide to the center, and through the hinge rod 303, the rotating plate 302 is driven to repeatedly deflect around the fixed shaft in the frame 301, so as to assist the flow of the raw material; when the feeding device moves above the mixing and stirring equipment, the magnet outside the top of the equipment and the magnetic block 39 at the bottom of the sealing plate 38 are opposite poles and generate an attractive force, which pulls the sealing plate 38 to deflect downward around the shaft body of the bottom support 37, stretches the elastic strip 30, and separates the sealing plate 38 from the discharge port of the second feeding cylinder 36, so that the liquid sodium silicate solution flows into the stirring equipment through the discharge port. During this process, the sealing mechanism 4 synchronously strengthens the sealing of the first feeding mechanism 2: when the center platform 13 moves downward, the first block 10 is blocked from moving downward by the bridge 18 below, and at the same time, the elastic telescopic rod 19 arranged at the top of the first block 10 is compressed, the first sliding block 104 on the second block 101 moves downward along the groove of the first block 10, and extrudes the flat plate 46; the flat plate 46 moves downward to compress the third spring 45, which pushes the first piston 44 in the first sleeve rod 41 to move downward along the first air pipe 42, the change of air pressure in the air pipe makes the bottom first reset telescopic plate 43 unfold, adhere to the bottom of the first feeding cylinder 25 and limit the column body 26, strengthen the sealing, prevent the liquid raw material from leaking.

[0040] Example two, driving mechanism switching and first feeding mechanism feeding stage.

[0041] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 , and Figure 12 , the core bearing of the first feeding mechanism 2 is the first slotted plate 21, which is fixed by welding through the transition piece second plate 17 and the first plate 15: the second plate 17 is in L-shaped structure, one of the right angles is welded with the outer side wall of the first plate 15, and the other right angle is full-welded with the outer side of the first slotted plate 21. The inside of the first slotted plate 21 is provided with a groove, and the cylinder body of the first electric push rod 22 is installed in the inside of the first slotted plate 21 by bolts; The bottom of the first slotting plate 21 is connected with the top end of the first feeding cylinder 25 by welding. The cylinder 26 inside the first feeding cylinder 25 is in clearance fit with the cylinder wall, and can smoothly slide along the cylinder wall in the axial direction. An annular clamping groove is formed on the outer side of the cylinder 26 near the top end. A limiting ring 28 is clamped in the clamping groove by interference fit. The outer diameter of the limiting ring 28 is slightly smaller than the inner diameter of the first feeding cylinder 25, and can slide synchronously with the cylinder 26, while limiting the sliding stroke of the cylinder 26 to prevent the cylinder 26 from being pulled out of the cylinder. A second spring 29 is sleeved on the outer side of the cylinder 26. The top end of the spring is in contact with the bottom of the first feeding cylinder 25, and the bottom end is in contact with a preformed annular step on the outer side of the cylinder 26, thereby providing an upward restoring force for the cylinder 26. Two groups of symmetrical notches are formed on the side surface of the cylinder 26 in the axial direction. The length of the notches is adapted to the height of the discharging channel of the first feeding cylinder 25. When the cylinder 26 slides to a specific position, the notches can be completely aligned with the discharging channel to form a material conveying channel. The top end of the first multi-fold rod 23 is fixedly connected with the output shaft of the first electric push rod 22 through a shaft coupling. The bottom end of the first multi-fold rod 23 is connected with the trapezoidal block 27 by butt welding. The inclined surface of the trapezoidal block 27 faces the cylinder 26, and the inclined surface is completely in contact with the conical surface at the top end of the cylinder 26. The contact surface is polished to reduce the frictional resistance when the two are pressed. When the first multi-fold rod 23 moves inward under the action of the first electric push rod 22, the inclined surface of the trapezoidal block 27 can precisely press the conical surface of the cylinder 26 to push the cylinder 26 to slide downward along the cylinder wall. The second sleeve rod 47 of the sealing mechanism 4 is connected with the second slotting plate 32 by vertical welding. The welding position is located at the central region of the outer side of the second slotting plate 32. A cylindrical cavity is formed in the inside of the second sleeve rod 47. The second air pipe 48 is fixed in the cavity by interference fit, and the outer wall of the air pipe is in close contact with the inner wall of the second sleeve rod 47. One end of the second air pipe 48 extends to the outside of the top end of the second sleeve rod 47. The number of the third air pipes 401 is two, and the bottom ends of the two third air pipes 401 are respectively connected with the air cavity interfaces of the two second reset telescopic plates 402 one by one. The two second reset telescopic plates 402 are uniformly distributed on the outer side of the bottom of the second feeding cylinder 36. The second piston 49 is slidably arranged in the cavity at the top end of the second air pipe 48. A circular groove is formed on the outer side of the second piston 49. The bottom end of the fourth spring 40 is embedded in the groove and fixed with the piston. The top end of the fourth spring 40 is welded with the top end cover of the second air pipe 48. When the external force pushes the second piston 49 to move upward, the piston can press the gas in the second air pipe 48, so that the gas enters the air cavity of the second reset telescopic plate 402 through the third air pipe 401 to push the telescopic plate to expand. When the external force disappears, the fourth spring 40 can push the second piston 49 to reset upward, the gas in the air pipe flows back, and the telescopic plate resets.

[0042] In this process, the sealing mechanism 4 synchronously strengthens the sealing of the second feeding mechanism 3: the center table 13 moves up, driving the first block 10 and the second block 101 to move up, the first block 10 extrudes the second piston 49 in the second sleeve rod 47, the second piston 49 compresses the fourth spring 40 into the second air pipe 48, causing the air pressure in the second air pipe 48 and the third air pipe 401 to change, making the second reset expansion plate 402 unfold and tightly fit the bottom of the second feeding cylinder 36, ensuring that there is no leakage in the non-working state. After the feeding is completed, the first electric push rod 22 is retracted, the second spring 29 rebounds to drive the cylinder 26 to reset, the slot is misaligned with the discharge channel, and the first feeding cylinder 25 is closed.

[0043] Example three, sealing mechanism continuous sealing and device reset stage.

[0044] As shown in Figure 11 and Figure 12 , no matter which feeding mechanism works, the sealing mechanism 4 always maintains the strengthened sealing of the non-working mechanism: when the first feeding mechanism 2 works, the first reset expansion plate 43 retracts and the second reset expansion plate 402 unfolds to seal the second feeding cylinder 36; when the second feeding mechanism 3 works, the second reset expansion plate 402 retracts and the first reset expansion plate 43 unfolds to seal the first feeding cylinder 25. During the gap of the alternating work of the two mechanisms, the hydraulic rod 12 drives the center table 13 to return to the middle position, and the surrounding plate 14 simultaneously limits the first top rod 24 and the second top rod 35, so that both feeding mechanisms are in a sealed state; the elastic expansion rod 19 and the first spring 16 reset, preparing for the next feeding switch; the reset expansion plates of the sealing mechanism 4 recover to the initial state under the action of air pressure and spring, ensuring that the sealing structure has no deformation.

[0045] The working principle of the present application: the driving mechanism 1 is the core control unit of the feed switching and sealing. When the hydraulic rod 12 is started, the center table 13 is pushed to move up and down in the vertical direction, the surrounding plate 14 outside the center table 13 moves synchronously, the two sides of the first spring 16 deforms with the surrounding plate 14 up and down, buffers the impact of lifting and assists the center table 13 to reset. The elastic telescopic rod 19 at the bottom of the center table 13 drives the first block 10 and the second block 101 to move synchronously, when the driving mechanism 1 triggers the second feeding mechanism 3, that is, when the surrounding plate 14 moves downward, the hole on the surface will cover the first ejector rod 24 and limit it, on the contrary, the second ejector rod 35 in the second feeding mechanism 3 is not restricted, and at the same time, the second electric push rod 33 is started, which pushes the second multi-fold rod 34 to slide towards the center, and the bottom end drives the rotating plate 302 to rotate around the fixed shaft in the frame 301 through the hinged rod 303. In addition, when the whole feeding device moves above the mixing and stirring equipment, the external magnet arranged at the top of the stirring equipment will generate an attractive force with the magnetic block 39 at the bottom of the sealing plate 38, so that the sealing plate 38 deflects downward through the shaft in the bottom support 37 and stretches the elastic strip 30, at this time, the sealing plate 38 is separated from the discharge port of the second feeding cylinder 36, and the raw materials are discharged through the discharge port; after the feeding is completed, the feeding device rises and resets, and at the same time, the magnet and the magnetic block 39 are away from each other, and the elastic strip 30 rebounds to drive the sealing plate 38 to reset.

[0046] When the driving mechanism 1 triggers the first feeding mechanism 2, that is, when the surrounding plate 14 moves upward, the hole on the surface will cover the second ejector rod 35 and limit it, on the contrary, the first ejector rod 24 in the first feeding mechanism 2 is not restricted, and at the same time, the first electric push rod 22 is started, which pushes the first multi-fold rod 23 to slide along the inner wall of the first slotted plate 21, and the bottom end drives the trapezoidal block 27 to extend into the inside of the first feeding cylinder 25. The inclined surface of the trapezoidal block 27 is extruded and matched with the cylinder 26, which pushes the cylinder 26 to slide down along the bottom of the first feeding cylinder 25 and stretches the second spring 29, at this time, the slot on the surface of the cylinder 26 is aligned with the discharge channel of the first feeding cylinder 25, the cement liquid or solid-liquid mixed raw materials are discharged through the slot, and the feeding is completed; after the feeding is completed, the first electric push rod 22 is retracted, the second spring 29 rebounds to drive the cylinder 26 to reset, and the slot is misaligned with the discharge channel, realizing the sealing of the first feeding cylinder 25.

[0047] The sealing mechanism 4 is connected with the double feeding mechanism to realize the reinforced sealing of the bottom of the feeding device, avoiding the leakage of the non-feeding mechanism or the insufficient sealing of the feeding mechanism. When the first feeding mechanism 2 does not work, the outer side of the first sleeve rod 41 is affected by the associated force, that is, the center table 13 and the surrounding plate 14 move downward synchronously, so that the two elastic expansion rods 19 at the bottom of the center table 13 move downward with the first block 10 and the second block 101 respectively. However, the first block 10 is arranged below the bridge 18, so that the first block 10 is blocked and cannot move downward, and at the same time, the elastic expansion rod 19 fixedly installed at the top of the first block 10 is compressed. At the same time, the first sliding block 104 on the second block 101 moves downward along the groove arranged on the surface of the first block 10, until the downward extrusion of the plane plate 46, the downward compression of the third spring 45, the pushing of the first piston 44 along the first air pipe 42, the change of the air pressure in the first air pipe 42, the unfolding of the bottom of the first reset expansion plate 43, the close contact with the bottom of the first feeding cylinder 25 and the limiting of the cylinder 26, and the reinforcement of the sealing. On the contrary, when the second feeding mechanism 3 does not work, the outer side of the second sleeve rod 47 is affected by the associated force, that is, the first block 10 and the second block 101 move upward synchronously, so that the first block 10 extrudes the second piston 49, the second piston 49 compresses the fourth spring 40 and extends into the second air pipe 48, and then the air pressure change in the second air pipe 48 and the third air pipe 401 makes the bottom of the second reset expansion plate 402 unfold and closely contact with the bottom of the second feeding cylinder 36, so as to ensure the sealing in the non-working state. Therefore, when the second feeding mechanism 3 works, the sealing mechanism 4 reverses the action to reinforce the sealing of the first feeding cylinder 25, always maintains the sealing reliability of the whole device, and avoids the leakage and pollution or waste of raw materials.

Those skilled in the art can make various modifications without creative labor, which are all within the protection scope of the present application.
