[0020] The present invention will be further described in detail below with reference to embodiments:
[0021] This utility model discloses an alumina segment sand making device. (Refer to...) Figure 1-5 The device includes a processing cylinder 1 and a top cover 2. A feeding pipe 3 with a mounting cover is installed on one side of the top of the top of the top cover 2 for adding alumina. An installation groove 4 is opened on the top of the inner side of the processing cylinder 1. An installation plate 5 is installed on the bottom of the top cover 2 and is installed in the installation groove 4. A crushing mechanism for crushing alumina is installed on the top of the inner side of the processing cylinder 1. A filtering mechanism for filtering the crushed alumina is installed on the bottom of the inner side of the processing cylinder 1.
[0022] By adopting the above technical solution, this utility model, through its crushing and filtering mechanisms, facilitates the addition of alumina into the processing cylinder 1 via the feeding pipe 3. The motor 15 drives the drive rod 16 to rotate, thereby rotating the guide plate 9. This crushes the alumina falling between the guide plate 9 and the crushing ring 6. The crushed alumina then falls into the mounting frame 11 via the connecting ring 8. Several limiting rings 14 sequentially support the falling crushed alumina. The motor 15 drives the mounting frame 11 to rotate via the connecting rod 17, and centrifugal force drives the crushed alumina towards the filter screen 13. The filter screen 13 filters the crushed alumina, which is then collected in the collection box 19. This multi-stage filtration system effectively filters and collects the crushed alumina, improving processing efficiency.
[0023] Reference Figure 1-5 The crushing mechanism includes a crushing ring 6, the outer side of which is installed in the mounting groove 4, and a number of crushing holes 7 are opened on the inner side of the crushing ring 6. A connecting ring 8 is installed at the bottom end of the crushing ring 6, and the connecting ring 8 is inclined downward from the outside to the inside.
[0024] By adopting the above technical solution, the connecting ring 8 facilitates the concentrated movement of the crushed alumina towards the inside of the mounting frame 11, thereby allowing it to be filtered through the filter screen 13.
[0025] Reference Figure 1-5The crushing mechanism also includes a guide plate 9, which is inclined downward from the inside out. Several isolation plates 10 are fixedly installed on the top of the guide plate 9, and the tops of the isolation plates 10 are all arc-shaped.
[0026] By adopting the above technical solution, by setting the guide plate 9, the material can be moved from the middle to the outside, so that the crushing ring 6 and the crushing hole 7 can cooperate with the outside of the guide plate 9 for crushing. The isolation plate 10 can isolate the material, thereby avoiding material accumulation and blockage.
[0027] Reference Figure 1-5 The filtration mechanism includes a mounting frame 11, the top of which is fixedly connected to the bottom of the connecting ring 8. Several fixing grooves 12 are evenly provided on both sides of the mounting frame 11, and filter screens 13 are fixedly installed in each fixing groove 12.
[0028] By adopting the above technical solution, the filter screen 13 facilitates the centrifugal force to drive the pulverized alumina to move towards the filter screen 13, and the filter screen 13 filters the pulverized alumina.
[0029] Reference Figure 1-5 A number of limiting rings 14 are evenly installed on the inner side of the mounting bracket 11. The outer sides of the limiting rings 14 are respectively matched with the inner side of the fixing groove 12, and the inner diameter of the limiting rings 14 is arranged in a frustum shape from top to bottom.
[0030] By adopting the above technical solution, the limiting ring 14 allows the crushed alumina to pass through the limiting ring 14 and the filter screen 13 in sequence for filtration. This multi-stage filtration process ensures that the crushed alumina is fully filtered and collected, thereby improving processing efficiency.
[0031] Reference Figure 1-5 A motor 15 is fixedly installed on the top of the top cover 2. The output shaft of the motor 15 passes through the top cover 2. A drive rod 16 is installed on the output shaft of the motor 15. The top of the drive rod 16 is fixedly connected to the guide plate 9. A connecting rod 17 is fixedly installed on the inner side of several limiting rings 14. One end of the connecting rod 17 is fixedly connected to the drive rod 16.
[0032] By adopting the above technical solution, the connecting rod 17 facilitates the motor 15 to drive the mounting frame 11 to rotate, thereby centrifugal force can drive the crushed alumina to move towards the filter screen 13, the filter screen 13 filters the crushed alumina and collects it through the collection box 19.
[0033] Reference Figure 1-5The bottom of the mounting frame 11 is fixedly installed with a discharge pipe 18, and the end of the discharge pipe 18 passes through the processing cylinder 1. Several collection boxes 19 are installed on both sides of the mounting frame 11, and the ports of the collection boxes 19 are respectively matched with several filter screens 13.
[0034] By adopting the above technical solution, the alumina filtered by the corresponding filter screen 13 can be collected through the set collection box 19.
