DETAILED DESCRIPTION
[0024] In order to more clearly explain the overall concept of the present application, the following will be described in detail in an exemplary manner combined with the drawings of the specification.
[0025] As Figures 1-5The utility model discloses a rotary kiln fish scale movable type fastening device, including rotary kiln body 1, the kiln wall of rotary kiln body 1 is fixedly connected first mounting ring 2, the kiln tail of rotary kiln body 1 is fixedly connected second mounting ring 3, and the outside of first mounting ring 2 with second mounting ring 3 is fixedly connected a plurality of first fixed column 4 with second fixed column 5 respectively, and a plurality of fish scale sealing sheets 6 are installed between first fixed column 4 with second fixed column 5, and the pressure tight fixed assembly 7 is equipped with on each fish scale sealing sheet 6, and when installing, the two through -holes on the first mounting plate 8 on fish scale sealing sheet 6 are aligned with two first fixed column 4, and the through slot on second mounting plate 9 is aligned with two second fixed column 5, fish scale sealing sheet 6 is installed between first mounting ring 2 with second mounting ring 3, and is fixed using pressure tight fixed assembly 7, and fish scale sealing sheet 6 is installed and is dismantled more convenient and fast through the pressure tight fixed assembly 7 replacement screw and nut to fish scale pressure tight sheet and fix, save time.
[0026] As Figures 2 to 5As shown, both ends of all the fish-scale sealing sheets 6 are fixedly connected to the first mounting plate 8 and the second mounting plate 9, respectively. The first mounting plate 8 fits against the first mounting ring 2, and the second mounting plate 9 fits against the second mounting ring 3. The first mounting plate 8 has two through holes that mate with the first fixing post 4. The second mounting plate 9 has two through slots that mate with the second fixing post 5. The clamping and fixing assembly 7 includes two clamping boxes 71, each of which is rotatably connected to a rotating rod 72. A horizontal plate 73 is fixedly connected to the outside of the rotating rod 72. The upper surface of the box 71 is provided with a sliding groove, in which a sliding block 74 is slidably connected. A plug rod 75 is fixedly connected to one side of the sliding block 74. A first spring 76 is fixedly connected between the sliding block 74 and the sliding groove. Both the first fixing post 4 and the second fixing post 5 are provided with slots. The slots on two adjacent first fixing posts 4 are opposite each other, and the slots on two adjacent second fixing posts 5 are opposite each other. The two pressing boxes 71 and their internal structures are of different sizes, but their internal structures are the same. The smaller pressing box 71 is adapted to the first mounting plate 8, and the larger pressing box 71 is adapted to the second mounting plate 8. In use, mounting plate 9 is used by placing the smaller clamping box 71 over the first mounting plate 8 and the larger clamping box 71 over the second mounting plate 9. The two clamping boxes 71 cover the two first fixing posts 4 and the two second fixing posts 5 respectively. The two horizontal plates 73 are located between the two first fixing posts 4 and the two second fixing posts 5 respectively. Rotating the rotating rod 72 causes the horizontal plates 73 to rotate, and both ends of the horizontal plates 73 extend into the slots. The slots on adjacent first fixing posts 4 are in opposite directions, and the same applies to the second fixing posts 5, but the slots on the opposite first fixing posts 4 and the second fixing posts 5 are in opposite directions. The slots on the fixed column 5 are in the same direction. During installation, the slots on the first fixed column 4 on the first mounting plate 8 are opposite each other, and the slots on the second fixed column 5 on the first mounting plate 8 are opposite each other. When the horizontal plate 73 rotates, the horizontal plate 73 will be locked in the slots on the two first fixed columns 4 and the two second fixed columns 5, so that the clamping box 71 is fixed on the first mounting plate 8 and the second mounting plate 9, and the first mounting plate 8 and the second mounting plate 9 are fixed, thereby fixing the fish scale sealing sheet 6. Compared with screws and nuts, the installation is more convenient.
[0027] like Figure 4 As shown, the lower surface of the rotating rod 72 is provided with a sliding hole, and a sliding rod 13 is slidably connected in the sliding hole. The upper end of the sliding rod 13 is fixedly connected to the sliding hole with a second spring 14. During installation, before the clamping box 71 is pressed on the first mounting plate 8 and the second mounting plate 9, the sliding rod 13 abuts against the first mounting plate 8 and the second mounting plate 9. As the clamping box 71 comes into close contact with the first mounting plate 8 and the second mounting plate 9, the sliding rod 13 slides on the rotating rod 72, and the second spring 14 is stretched and stores force. When the horizontal plate 73 is stuck in the slot, the second spring 14 pulls the horizontal plate 73 and the slot to make the contact between them tighter and prevent shaking. After installation, a flexible integrated sealing rubber sleeve is fitted on the outside of the fish scale sealing sheet 6, which can effectively reduce the air leakage rate and play a good wind-blocking role, so as to maintain a stable negative pressure environment in the rotary kiln.
[0028] like Figure 3 As shown, a clamping plate 10 is fixedly connected between the two clamping boxes 71. The clamping plate 10 is located above the fish scale sealing sheet 6. The clamping plate 10 and the fish scale sealing sheet 6 are offset. When the fish scale sealing sheet 6 is installed, there is a clamping plate 10 in the gap between the fish scale sealing sheets 6. The clamping plate 10 contacts the fish scale sealing sheet 6 and restricts the fish scale sealing sheet 6 to prevent the fish scale sealing sheet 6 from deforming and expanding outward.
[0029] like Figure 1 and Figure 3 As shown, a square fixing ring 11 is fixedly connected to one side of all the pressing plates 10. Multiple steel wire ropes 12 are sleeved inside the square fixing ring 11. The multiple steel wire ropes 12 bind and squeeze the pressing plates 10, and the pressing plates 10 press the fish scale sealing sheet 6 tightly, thereby improving the pressing effect on the fish scale sealing sheet 6.
[0030] Working principle: Align the two through holes on the first mounting plate 8 of the fish scale sealing sheet 6 with the two first fixing posts 4, and align the through groove on the second mounting plate 9 with the two second fixing posts 5. Install the fish scale sealing sheet 6 between the first mounting ring 2 and the second mounting ring 3. Cover the first mounting plate 8 with the smaller clamping box 71 and the second mounting plate 9 with the larger clamping box 71. The two clamping boxes 71 cover the two first fixing posts 4 and the two second fixing posts 5 respectively. The two horizontal plates 73 are located between the two first fixing posts 4 and the two second fixing posts 5 respectively. Rotate the rotating rod 72 to make the horizontal plates 73 rotate. The two ends of the horizontal plates 73 extend into the slots. At this time, there is a clamping plate 10 in the gap between the fish scale sealing sheets 6. The steel wire rope 12 is sleeved in the square fixing ring 11.
