[0002] The extraction tower is a turntable tower container, which contains 74 layers of sieve turntables and 96 layers of turntables, a total of 170 layers of turntables. The central axis is divided into three sections: upper axis, middle axis and lower axis. The assembly size requirements of the turntable and the central axis are relatively high. During operation, the process medium promotes the dispersion of droplets and improves the mass transfer efficiency of the medium through the rotation of the turntable and the interaction of the tower body fixed ring disk, so as to achieve the extraction of the process medium. This requires that the spacing between adjacent turntables is uniform, so that each layer of turntable is located in the middle of two adjacent fixed ring disks after the turntable assembly is installed; at the same time, the horizontality of the turntable surface should be ensured to ensure that the process medium does not deviate in this plane, so as to achieve the requirement of uniform dispersion of the process medium.

[0031] like Figure 1-Figure 7 The turntable type stirring assembly installation structure shown includes a static balance test device and a horizontal installation structure. First, a static balance test is performed on the turntable of the stirring assembly through the static balance test device, and then the turntable is installed on the central axis through the horizontal installation structure.

[0032] Specifically, the static balance experimental device is as follows: Figure 1 As shown, it is composed of a bracket 1, a rotating shaft 2, a bearing 3, a clamping nut 4, a first pressure plate 5 and a second pressure plate 6. Two groups of coaxially distributed bearings 3 are arranged above the bracket 1. Both ends of the rotating shaft 2 in the length direction are rotatably connected to the top of the bracket 1 through the bearings 3. The first pressure plate 5 and the second pressure plate 6 are coaxially fixedly connected to the rotating shaft 2, and the two are distributed at a certain interval. A circular boss is integrally formed on the inner side surface of the second pressure plate 6, and the circular boss is coaxially arranged with the second pressure plate 6. The diameter of the circular boss is slightly smaller than the inner hole diameter of the turntable 7, and the thickness of the circular boss is smaller than the thickness of the turntable 7. Two groups of clamping nuts 4 are arranged, which are respectively located on the outside of the first pressure plate 5 and the second pressure plate 6. The clamping nuts 4 are coaxially threaded with the rotating shaft 2, and the turntable to be detected is arranged between the first pressure plate 5 and the second pressure plate 6. The first pressure plate 5 and the second pressure plate 6 can be clamped by two groups of clamping nuts 4, so as to fix the turntable 7.

[0033] The turntable 7 of the stirring assembly is inspected by using a static balance test device. The turntable 7 is fixed between the first pressure plate 5 and the second pressure plate 6 and is tightened and fixed by two sets of compression nuts 4. The turntable 7 is rotated to check the random stop position. It is qualified if it is balanced. If it is unbalanced, the turntable 7 is ground and the experiment is continued until the turntable 7 is qualified to complete the inspection of the turntable 7. The turntable is subjected to a static balance test by using a static balance test tool to verify the uniformity of the turntable quality. If there is an imbalance, the turntable is ground and adjusted to ensure the levelness of the turntable after installation and the stability during rotation.

[0034] Horizontal installation structure Figure 2-Figure 7 As shown, it is composed of a base 8, a movable bracket 9, a fixed bracket 17 and a distance tube 11. The length of the base 8 is horizontally distributed in the left and right directions. The movable bracket 9 is arranged in multiple groups at intervals along the length direction of the base 8. A connecting plate 12 is welded on the upper end of the movable bracket 9. The upper end surface of the connecting plate 12 is provided with a first arc groove for fitting with the outer cylindrical surface of the distance tube 11. A first supporting plate 13 is arranged above the connecting plate 12. Bolt holes corresponding to the positions are arranged on the first supporting plate 13 and the connecting plate 12. The two are detachably fixedly connected by fixing bolts 14 and nuts, and the first supporting plate A second arc groove is provided on the upper end surface of 13, which is used to fit with the outer cylindrical surface of the central axis 10 of the turntable stirring assembly; a second support plate 18 is fixedly connected above the fixed bracket 17, and a third arc groove is provided on the upper end surface of the second support plate 18, which is used to fit with the outer cylindrical surface of the central axis 10 of the turntable stirring assembly; a plurality of groups of distance tubes 11 are provided, and the plurality of groups of distance tubes 11 are coaxially fixed on the outside of the central axis 10 and are spaced apart along the length direction of the central axis 10, and the distance tubes 11 are located between the two turntables 7, and the spacing between two adjacent groups of turntables 7 can be controlled by the distance tubes 11.

[0035] The bottom of the movable bracket 9 is rotatably connected to the base 8 through a rotating seat 15. Figure 4 , Figure 5 as well as Figure 6 As shown, the rotating seat 15 is composed of two groups of vertical plates 1501 and a rotating shaft 1502. The two groups of vertical plates 1501 are fixedly connected to the top of the base 8 and are spaced apart from each other to form a rotating groove. The size of the rotating groove is larger than the size of the lower part of the movable bracket 9, so that the movable bracket 9 can rotate in the rotating groove easily. The vertical plates 1501 and the lower part of the movable bracket 9 are provided with through holes corresponding to the positions. The rotating shaft 1502 is distributed in the front and rear directions and passes through the above-mentioned through holes. The movable bracket 9 is connected to the rotating seat 15 for left and right rotation through the rotating shaft 1502.

[0036] A limiting mechanism is provided between the movable bracket 9 and the rotating seat 15, and the limiting mechanism includes a movable limiting member and a fixed limiting member. The fixed limiting member is a limiting channel steel 901 fixedly connected to the right side of the lower end of the movable bracket 9, and the movable limiting member is composed of a limiting boss 1503 and a limiting plate 16 fixedly connected to the upper left end of the vertical plate 1501; the lower end surface of the limiting channel steel 901 is flush with the lower end surface of the movable bracket 9. When the movable bracket 9 is in a vertical state, due to the limiting effect of the limiting channel steel 901, the movable bracket 9 cannot continue to rotate to the right; the limiting boss 1503 is provided with two groups and is located at the front and rear ends respectively. At the upper left end position of the rear two vertical plates 1501, the gap between the two groups of limiting bosses 1503 is the same as the gap between the two groups of vertical plates 1501. When the movable bracket 9 is in a vertical state, a limiting groove is formed between the left side of the movable bracket 9 and the right side of the limiting boss 1503. The limiting plate 16 is clamped in the limiting groove to fix the movable bracket 9, so that the movable bracket 9 is kept in a vertical state. When the angle of the movable bracket 9 needs to be adjusted, the limiting plate 16 is taken out, and the movable bracket 9 can be rotated 90° to the left in the rotating groove through the rotating shaft 1502 until it is as shown in FIG. Figure 6 Status shown.

[0037] After the static balance test of the turntable 7 is completed, the turntable 7 is assembled using a horizontal installation structure. First, the movable bracket 9 is installed above the base 8. The movable bracket 9 is distributed in the vertical direction and fixed by the limit plate 16. At the same time, it is ensured that the first arc grooves on the connecting plates 12 in the multiple groups of movable brackets 9 are concentrically distributed; then the first support plate 13 is fixed to the connecting plate 12 by bolts, and the multiple groups of first support plates 13 are kept concentrically distributed; then the central axis 10 is placed in the arc grooves on the first support plate 13 and the second support plate 18; the movable bracket 9 is placed horizontally, and the turntable 7 and the distance tube 11 are installed from left to right in sequence. When installed to the position of the movable bracket 9, since the diameter of the distance tube 11 is larger than the central axis 10, it is necessary to remove the first support plate 13 on the movable bracket 9 so that the distance tube 11 fits the first arc groove on the connecting plate 12. Repeat the above steps to complete the installation of all the turntables 7 and the distance tube 11.

[0038] Use the turntable assembly tool to place the shaft horizontally for turntable assembly installation, which is convenient for measuring and checking the turntable spacing and improving the quality of turntable assembly. The gap deviation of the turntable group is controlled within 0.5mm, meeting the manufacturing process requirements. The horizontal installation form reduces the risk of operators working at heights, improves working conditions, reduces the labor intensity of operators, and improves working efficiency.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
