Description

Technical Field

[0001] The invention relates to the technical field of autoclaved brick shaping, in particular to a fly ash recycling autoclaved brick production device and a process thereof. Background Art

[0002] Fly ash autoclaved brick is a new type of wall material made of fly ash, lime or cement as the main raw materials, mixed with appropriate amount of gypsum and aggregate, and made through blank preparation, pressing and high temperature and high pressure steam curing. The main raw materials are fly ash, lime or cement, mixed with appropriate amount of gypsum and aggregate, mixed through a precise batching system, and then pressed and cured by high temperature and high pressure steam. The size of fly ash autoclaved brick is exactly the same as that of ordinary solid clay brick, which is 240mm x 115mm x 53mm. It can directly replace solid clay brick. Fly ash autoclaved brick has the characteristics of light weight, heat preservation, heat insulation, and machinability. It is mainly used for walls and foundations of industrial and civil buildings.

[0003] In the conventional production process, fly ash needs to be mixed with other ingredients and poured into a mold for shaping. During the shaping period, in order to quickly increase the shaping speed, it is usually necessary to strictly control the ratio of water to fly ash, so that the cement poured into the mold becomes particularly viscous. However, since the previous stirring is carried out through continuous rotation and stirring, there will be more air bubbles in the cement, which will reduce the strength of the autoclaved bricks. In addition, during the 24 to 48 hours of curing period, the cement itself settles downward before solidifying, causing the excess water to float upward, so that the strength of the autoclaved bricks after curing will gradually decrease from the bottom to the top.

[0015] Autoclaved brick production process:

[0016] S1: Pour cement into the mold, then the hydraulic rod drives the mounting frame and the extrusion block to press the cement in the mold to initially stabilize the cement. Then the hydraulic rod drives the mounting frame and the extrusion block to lift up slightly, the cylinder drives the vibration rod and the plastic shell to insert into the cement, and the motor drives the camshaft to rotate, so that the excess water and air in the cement quickly float up to form a floating layer.

[0017] S2: The motor stops, and cylinder 1 drives the vibration rod back to its original position. During this period, the plastic shell is forced to remain in the cement because the sealing component is stuck in the plastic shell. Cylinder 2 drives the sealing plug upward and starts the hydraulic rod to continue to drive the mounting frame and the extrusion block to press the cement in the mold downward. The water forming the floating layer will be discharged outward through the flow groove and the drainage groove due to the pressure from above, so that the cement is re-shaped.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present application uses the cooperation between the extrusion block, the vibration rod, the plastic shell, the flow groove, the drainage groove, the sealing plug, the mounting frame, the cylinder 1, the cylinder 2 and the motor. After the stirred cement is poured into the mold, a hydraulic rod is installed just above the mold. The output end of the hydraulic rod is fixed to the mounting frame. The hydraulic rod can drive the entire device to move up and down through the mounting frame. When moving upward, the extrusion block can move downward to squeeze the cement in the mold, so that the cement is quickly deformed into a square shape. Then, the cylinder 1 pushes the vibration rod downward to move downward and insert it into the cement. When the vibration rod moves downward, it can drive the plastic shell to move downward together. The plastic shell can avoid direct contact between the cement and the vibration rod. Then, the vibration rod can be driven by the motor to vibrate rapidly to accelerate the sedimentation speed in the cement. Excess moisture and bubbles float up quickly. After completing this step, cylinder one drives the vibration rod back to its original position and leaves the plastic shell in the cement. At this time, cylinder two drives the sealing plug to move upward, and then the hydraulic rod continues to apply pressure downward. Subject to the pressure from above, the floating air and water will be discharged to the outside through the flow groove and the drainage groove. When the extrusion block reaches the specified height, the hydraulic rod stops pressurizing, and cylinder two pushes the sealing plug back to its original position to block the flow groove, so that excess moisture can be removed in time before the cement solidifies, and the excess water content in the cement is reduced, reducing the difference in rigidity between the upper and lower areas of the cement block after solidification, and solving the problem that the firmness of the autoclaved brick will gradually decrease from the bottom to the top due to air bubbles and more moisture.

[0020] 2. The cooperation between the plastic shell, the vibration rod, the directional rod, the reserved groove, the movable groove and the sealing assembly of the present application is that the vibration rod can move up and down through the space reserved by the movable groove. When the vibration rod moves downward with the plastic shell, it can push open the sealing assembly below, so that the sealing assembly can move to both sides through the reserved groove, so that the vibration rod can move normally. When the vibration rod is reset upward, since the overall diameter of the plastic shell is larger than the overall diameter of the vibration rod, the plastic shell will be stuck by the sealing assembly, so that the plastic shell will not be reset upward with the vibration rod, but will remain in the cement forever, thereby eliminating the possibility of cement entering the reserved groove.

[0021] 3. The reserved groove, sealing assembly, slide rail and directional groove of the present application are matched. When the sealing assembly moves, it can move through the directional groove and the slide rail. The directional groove and the slide rail can prevent the sealing assembly from shifting or misaligning when moving. BRIEF DESCRIPTION OF THE DRAWINGS

Then the vibration rod 2 can be driven by the motor 10 to vibrate rapidly, accelerate the sedimentation speed in the cement, and make the excess water and bubbles float up quickly. After completing this link, the cylinder 1 8 drives the vibration rod 2 back to its original position and leaves the plastic shell 3 in the cement. At this time, the cylinder 2 9 drives the sealing plug 6 to move upward, and then the hydraulic rod continues to apply pressure downward. Under the pressure from above, the floating air and water will be discharged to the outside through the flow groove 4 and the drainage groove 5. When the extrusion block 1 reaches the specified height, the hydraulic rod stops pressurizing, and the cylinder 2 9 pushes the sealing plug 6 back to its original position to block the flow groove 4, so that the excess water can be removed in time before the cement solidifies, and the excess water content in the cement is reduced, which reduces the difference in rigidity between the upper and lower areas of the cement block after solidification, and solves the problem that the firmness of the autoclaved brick will gradually decrease from the bottom to the top due to air bubbles and more water.

[0033] A slide groove is provided on the outer surface of the vibration rod 2, and a bearing 11 is sleeved on the outside of the vibration rod 2.

The motor 10 can drive one of the three bearings 11 and the camshaft 12 to rotate through the driving gear 14. The high-speed rotating camshaft 12 can generate vibration and transmit the vibration to the vibration rod 2 through the bearing 11, so that the vibration rod 2 can vibrate.

[0035] A movable groove 18 is provided on the inner side of the extrusion block 1, and a reserved groove 19 is provided on the inner side of the movable groove 18 of the extrusion block 1. A sealing component 20 is slidably connected to the inner wall of the reserved groove 19.

A directional rod 21 is slidably connected to the inner wall of the sealing component 20. One end of the directional rod 21 is fixedly installed on the inner surface of the reserved groove 19. The vibration rod 2 can move up and down through the space reserved by the movable groove 18. When the vibration rod 2 moves downward with the plastic shell 3, it can push open the sealing component 20 below, so that the sealing component 20 can move to both sides through the reserved groove 19, so that the vibration rod 2 can move normally. When the vibration rod 2 is reset upward, since the overall diameter of the plastic shell 3 is larger than the overall diameter of the vibration rod 2, the plastic shell 3 will be stuck by the sealing component 20, so that the plastic shell 3 will not be reset upward with the vibration rod 2, but will remain in the cement forever, thereby eliminating the possibility of cement entering the reserved groove 19.

[0036] A spring 22 is sleeved on the outer surface of the directional rod 21, one end of the spring 22 is fixedly installed on the inner surface of the reserved groove 19, and the other end of the spring 22 is fixedly installed on the outer surface of the sealing component 20. The directional rod 21 can provide a fixed moving direction for the reserved groove 19 and prevent the spring 22 from deforming in all directions. The spring 22 can always push the sealing component 20 to ensure that the sealing component 20 can jam the plastic shell 3 and can also be quickly reset.

[0037] Cylinder 1 8 is fixedly mounted on the outer surface of the mounting frame 7. There are two cylinders 2 9, which are distributed on both sides of cylinder 1 8. The outer surface of cylinder 2 9 and the outer surface of the mounting frame 7 are fixedly mounted.

[0038] A square plate 23 is fixedly installed at the output end of the cylinder 8, and the bottom surface of the square plate 23 and the top of the vibration rod 2 are fixedly installed. When the cylinder 8 outputs downward, it can drive the three vibration rods 2 to move at the same time through the square plate 23.

The outer surface of the limit ring 26 is slidably connected to the outer surface of the sealing plug 6. The limit ring 26 can provide a minimum limit for the sealing plug 6 to ensure that when the sealing plug 6 moves to the lowest height, its bottom surface can maintain the same height as the bottom surface of the limit ring 26 and the extrusion block 1, so that no obvious concave and convex marks will appear on the cement surface when the cement is pressed down. When the sealing plug 6 moves upward, the push of the extrusion block 1 can enable excess air and water to be discharged outward through the through-flow groove 4 and the drainage groove 5.

When the sealing component 20 moves, it can move through the orientation groove 28 and the slide rail 27. The orientation groove 28 and the slide rail 27 can prevent the sealing component 20 from shifting or misaligning when moving.

[0042] When using the equipment, cement is poured into the mold, and then the hydraulic rod drives the mounting frame 7 and the extrusion block 1 to move downward as a whole to extrude the cement in the mold, so that the cement is initially shaped as a whole, and then the hydraulic rod stops applying pressure, and the cylinder 1 8 drives the vibration rod 2 to move downward and insert into the cement, and the motor 10 drives the camshaft 12 to rotate, so that the vibration rod 2 vibrates, and the vibration can make the cement settle quickly and make the air and water inside float quickly, and then the cylinder 1 8 drives the vibration rod 2 back to its original position and leaves the plastic shell 3 in the cement, and then the cylinder 2 9 drives the sealing plug 6 to move upward, and starts the hydraulic rod to press down again. Under the pressure from above, the water and air can be discharged through the flow groove 4 and the drainage groove 5. When the extrusion block 1 is pressed down to the specified height, the cylinder 2 9 drives the sealing plug 6 back to its original position, and then the hydraulic rod drives the extrusion block 1 to press down slightly to shape the cement for the second time, and then drives the extrusion block 1 back to its original position.
