Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated block processing, in particular to an autoclaved aerated block casting device. Background Technique

[0002] During the processing of aerated blocks, first, concrete materials need to be poured into the mold frame. After the materials harden, they are cut into aerated blocks of the same specification size, and then pushed into the steam curing chamber for steam curing, thus completing the production and preparation of aerated blocks. Among them, during the casting and forming process, a casting device is required. The casting device can inject concrete materials into the mold frame and can also generate vibrations through a concrete vibrator to facilitate the discharge of air in the concrete and improve the product quality of aerated blocks. However, when the existing casting device is in use, the concrete is prone to accumulate directly below the casting outlet. During the casting process, it is necessary to stop casting for a period of time in the middle and then cast again, or reduce the casting volume per minute, but both will result in a longer casting time and it is difficult to meet the production requirements.

Specific Embodiments

[0017] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0018] As Figures 1-5As shown in the figure, an autoclaved aerated concrete block casting device includes a mounting frame 1. A fixing plate 3 is provided on the mounting frame 1. A through groove is formed in the fixing plate 3. A casting pipe 4 is installed inside the through groove. A cavity 5 is slidably connected to the outer surface of the casting pipe 4. Cylinders 6 are symmetrically arranged on the fixing plate 3. The output end of the cylinder 6 penetrates through the fixing plate 3 and is fixedly connected to the upper surface of the cavity 5. Rotating shafts 7 are respectively rotatably connected to both ends of the cavity 5. A motor 8 for driving the rotation of the rotating shaft 7 is arranged at the upper end of the cavity 5. A bottom plate 9 is arranged at the lower end of the rotating shaft 7. Mounting holes are evenly formed in the bottom plate 9. Vibrators 10 are fixedly connected inside the mounting holes. A grille 11 is arranged on the outer surface of the vibrator 10. The grille 11 is arranged in the outer direction of the bottom plate 9. The position of the grille 11 can effectively spread the concrete in the mold frame 2 and prevent the concrete from accumulating under the casting pipe 4 for a long time.

[0019] During use, the mold frame 2 needs to be placed inside the mounting frame 1. A conveying device can be arranged at the bottom of the mounting frame 1 to convey the empty mold frame 2 into the mounting frame 1 through the conveying device and transport the mold frame 2 filled with concrete out of the mounting frame 1. At the same time, rollers can also be arranged at the bottom of the mold frame 2 to push the mold frame 2 to move separately.

[0020] The upper end of the casting pipe 4 is connected to the discharging pipe of the concrete mixing equipment. A valve is arranged on the discharging pipe of the concrete mixing equipment. Open the valve, and pump the concrete in the concrete mixing equipment into the casting pipe 4 through a suction device and transport it to the mold frame 2 through the casting pipe 4.

[0021] During the process of transporting the concrete to the mold frame 2 through the casting pipe 4, the vibrator 10 needs to extend into the mold frame 2, as Figure 1As shown, in this case, as the concrete continuously enters the mold frame 2, the gas in the concrete is discharged through the vibrator 10, improving the forming quality of the aerated block. During the operation of the vibrator 10, two motors 8 on the cavity 5 are controlled to rotate simultaneously. The two motors 8 respectively drive the bottom plate 9 to rotate through the rotating shafts 7. The bottom plate 9 drives the vibrator 10 on the bottom plate 9 to rotate. During the rotation of the vibrator 10, through the grid 11 arranged on the vibrator 10, the concrete continuously accumulating directly below the pouring pipe 4 can be pushed towards both sides of the pouring pipe 4, thus preventing the concrete directly below the pouring pipe 4 from piling up too high and improving the efficiency of the concrete spreading evenly in the mold frame 2. After a predetermined amount of concrete is injected into the mold frame 2 and when the concrete in the mold frame 2 has been evenly dispersed, the motors 8 stop working, and the vibrator 10 still remains working. Then, two cylinders 6 are controlled to work simultaneously. The output ends of the cylinders 6 retract and drive the cavity 5 to move upward. The cavity 5 drives the bottom plate 9 and the vibrator 10 to move upward. When the vibrator 10 completely disengages from the concrete in the mold frame 2, the vibrator 10 continues to work for a period of time so that as much of the concrete on the surface of the vibrator 10 as possible can fall into the mold frame 2, preventing the concrete on the vibrator 10 from drying and hardening and damaging the vibrator 10.

[0022] When cleaning the concrete on the vibrator 10, the concrete on its surface can be cleaned either by the vibration of the vibrator 10 itself, or by controlling the bottom plate 9 to rotate rapidly by the motor 8 to throw out the concrete on the surface of the vibrator 10, or by controlling the vibration of the vibrator 10 while controlling the rapid rotation of the bottom plate 9, all of which can achieve the cleaning of the concrete on the surface of the vibrator 10.

[0023] Furthermore, an outer extension ring plate 12 is provided at the lower end of the pouring pipe 4. The lower surface of the outer extension ring plate 12 is a concave arc surface. When the concrete enters the mold frame 2 through the pouring pipe 4, concrete spattering will occur at the lower port of the pouring pipe 4. By providing the outer extension ring plate 12, the range and height of the concrete spattering can be reduced. At the same time, through the provided concave arc surface, after the concrete impacts the lower surface of the outer extension ring plate 12, as much of it as possible will enter the mold frame 2, preventing more concrete from splashing outside the mold frame 2.

[0024] Furthermore, a shock-absorbing washer 13 is provided inside the mounting hole. The vibrator 10 is fixedly installed inside the shock-absorbing washer 13. The shock-absorbing washer 13 can reduce the vibration of the vibrator 10 on the bottom plate 9, thereby improving the stability of the bottom plate 9 and the cavity 5. The shock-absorbing washer 13 is fixedly connected to the bottom plate 9, and the vibrator 10 is fixedly connected to the shock-absorbing washer 13.

[0025] Furthermore, the bottom plate 9 is circular, and shielding covers 14 are respectively arranged at both ends of the cavity 5. An arc-shaped groove is arranged on the shielding cover 14, and the bottom plate 9 rotates within the arc-shaped groove of the shielding cover 14. By providing the shielding cover 14, it is possible to shield a relatively large area of the opening above the mold frame 2, reducing the probability of the concrete in the mold frame 2 splashing out.

[0026] Furthermore, a reinforcing sleeve 15 is arranged on the upper end surface of the cavity 5. The reinforcing sleeve 15 is slidably connected to the pouring pipe 4, and the reinforcing sleeve 15 can increase the stability of the cavity 5 moving on the pouring pipe 4.

[0027] When the device is in use, during the process of continuously pouring concrete from the pouring pipe 4 into the mold frame 2, it can continuously disperse the poured concrete in the mold frame 2, thereby preventing the concrete from accumulating directly below the pouring pipe 4. On the premise of continuous and uninterrupted pouring of the pouring pipe 4, it ensures the pouring volume per minute, improves the pouring efficiency, and has a good use effect.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
