Detailed implementation manners

[0027] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0028] Embodiment 1:

[0029] Please refer to Figure 1-8, the utility model provides a fixing component for a distilling ammonia tower tray, which comprises four groups of U-shaped seats 1. The four groups of U-shaped seats 1 are fixedly connected to the upper surface of the inner ring plate 2 in a cross distribution. The inner ring plate 2 is fixedly connected to the inner wall of the tower body 3. Two groups of rotating seats 11 are fixedly connected to one side of the U-shaped seat 1. An L-shaped pressing plate 4 is rotatably connected to the inner sides of the two groups of rotating seats 11. Fixing holes 14 are respectively formed through the two side edges at the upper end of the U-shaped seat 1. A limiting rod 5 for restricting the rotation of the L-shaped pressing plate 4 is movably connected inside the fixing holes 14. A second threaded hole 42 is formed through the upper surface of the long side of the L-shaped pressing plate 4 and away from one end of the short side. An adjusting bolt 6 is threadedly connected inside the second threaded hole 42. The L-shaped pressing plate 4 fixes the tower tray 9 on the upper surface of the inner ring plate 2. The lower end of the adjusting bolt 6 abuts against the upper surface of the tower tray 9. Two groups of fixing seats 12 are fixedly connected to the other side of the U-shaped seat 1. A positioning block 7 is slidably connected to the inner sides of the two groups of fixing seats 12. A first threaded hole 13 is formed through the side surface of the U-shaped seat 1. A fixing bolt 8 is threadedly connected inside the first threaded hole 13. The end of the fixing bolt 8 abuts against one side of the positioning block 7. A through slot 41 is formed through the short side of the L-shaped pressing plate 4.

[0030] With the four groups of positioning blocks 7 of the utility model, when installing the tower tray 9, four-point positioning can be carried out on the side of the tower tray 9 to ensure that the installed tower tray 9 is in the correct position, reducing the positioning time. Secondly, by rotating the fixing bolt 8, the actual position of the positioning block 7 can be adjusted, so that the four groups of positioning blocks 7 can firmly limit the four points of the tower tray 9 under the abutting force of the fixing bolt 8, preventing displacement during the working process. Through the mutual cooperation of the U-shaped seat 1, the L-shaped pressing plate 4 and the limiting rod 5, the tower tray 9 can be fixed on the upper surface of the inner ring plate 2. Through the mutual cooperation of the L-shaped pressing plate 4 and the adjusting bolt 6, on the basis of the preliminary fixation of the L-shaped pressing plate 4, secondary fixation can be carried out on the upper surface of the tower tray 9 to make it more firm, which not only simplifies the disassembly and assembly process, but also improves the operation efficiency and reduces the maintenance time.

[0031] Specific operation steps: First, rotate and open the four groups of L-shaped pressing plates 4 in sequence. Then, place the tray 9 inside the four positioning blocks 7 on the inner ring plate 2. Next, rotate the four groups of L-shaped pressing plates 4 in the opposite direction to the inner side of the opening of the U-shaped seat 1, so that the lower surface of the L-shaped pressing plate 4 fits the upper surface of the tray 9. Then, insert the limiting rod 5 into the fixing hole 14. At this time, the position of the L-shaped pressing plate 4 is fixed. After the four groups of L-shaped pressing plates 4 are fixed, adjust the position of the positioning block 7 according to the actual cooperation between the tray 9 and the positioning block 7 (rotate the fixing bolt 8, and under the cooperation of the fixing bolt 8 and the first threaded hole 13, it gradually moves towards the tray 9 direction, so as to firmly abut the positioning block 7 against the side of the tray 9), so that the tray 9 is firmly fixed inside the four positioning blocks 7. Finally, adjust the height of the adjusting bolt 6 according to the cooperation between the L-shaped pressing plate 4 and the tray 9. By rotating the adjusting bolt 6, the lower end of the adjusting bolt 6 firmly abuts the upper surface of the tray 9, thereby locking the position of the tray 9.

[0032] Furthermore, square frames 44 are symmetrically and fixedly connected to both sides of the L-shaped pressing plate 4, and the upper ends of both sides of the U-shaped seat 1 are movably connected inside the square frames 44.

[0033] Specifically, during the process of the L-shaped pressing plate 4 being buckled, the upper ends of both sides of the U-shaped seat 1 will gradually be inserted into the square frames 44. The function of the square frames 44 is to ensure that the L-shaped pressing plate 4 moves along the correct trajectory during the buckling process, playing a role of positioning and guiding, so as to ensure the precise docking between the L-shaped pressing plate 4 and the U-shaped seat 1.

[0034] Furthermore, a movable block 61 is rotatably connected to the lower end of the adjusting bolt 6, and a placement groove 43 for accommodating the movable block 61 is opened at the lower end of the second threaded hole 42.

[0035] Specifically, when the height of the adjusting bolt 6 is adjusted downward, it will drive the movable block 61 to move downward accordingly. At this time, the movable block 61 will come into contact with the upper surface of the tray 9, thereby increasing the force-bearing area of the adjusting bolt 6 and making the force distribution more uniform. This design not only enhances the contact area between the adjusting bolt 6 and the tray 9, but also can effectively reduce the local pressure, improve the fixing effect, and ensure the stability of the tray 9.

[0036] Furthermore, a sliding groove 121 is opened inside the fixing seat 12, and sliding blocks 71 are fixedly connected to both sides of the positioning block 7. The sliding blocks 71 are slidably connected inside the sliding groove 121.

[0037] Specifically, when adjusting the position of the positioning block 7, by rotating the fixing bolt 8, the end of the fixing bolt 8 abuts against the positioning block 7 and slides towards the tray 9 direction. During the sliding process of the positioning block 7, the positioning block 7 drives the sliding block 71 to slide inside the sliding groove 121. The sliding groove 121 plays a role of positioning and limiting the sliding block 71, ensuring that the positioning block 7 can only slide along the path of the sliding groove 121.

[0038] Further, through holes 51 are respectively formed through both outer ends of the limiting rod 5, and a locking buckle 52 is detachably connected inside the through holes 51.

[0039] Specifically, the locking buckle 52 can be made of a wire buckle made of stainless steel to ensure durability and firmness. After the limiting rod 5 is inserted into the fixing hole 14 in place, the locking buckle 52 can be inserted into the through holes 51 at both ends of the limiting rod 5. At this time, the limiting rod 5 cannot slide out of the fixing hole 14, effectively preventing the movement of the limiting rod 5.

[0040] Embodiment 2:

[0041] Please refer to Figure 1-9 , on the basis of Embodiment 1, as another implementation manner of the present utility model, threads are provided on the outer side of the limiting rod 5, and nuts 53 are threadedly sleeved on both ends of the limiting rod 5.

[0042] Specifically, after the limiting rod 5 is inserted into the fixing hole 14, the nuts 53 are threadedly sleeved on both ends of the limiting rod 5, and the locking of the limiting rod 5 can be completed, preventing it from sliding out of the fixing hole 14.

[0043] Embodiment 3:

[0044] Please refer to Figure 1-9 , on the basis of Embodiment 1, as another implementation manner of the present utility model, threads are provided on the inner side of the fixing hole 14, and the limiting rod 5 is threadedly connected inside the fixing hole 14.

[0045] Specifically, when fixing the limiting rod 5, the limiting rod 5 can be directly screwed into the two groups of fixing holes 14, and at this time, the limiting rod 5 is in a limited state.

[0046] The above are only the preferred implementation manners of the present utility model and are not used to limit the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
