For example, "connected" 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 a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figures 1 to 4As shown, the assembly connection structure for the distillation tower in this embodiment includes two distillation tower tubes 1, and the distillation tower is composed of a plurality of distillation tower tubes 1. A filler is installed at the connection between the two distillation tower tubes 1, and a partition is installed at the connection between every two distillation tower tubes 1. The upper end of the partition is installed with a filler, and two supporting arc plates 6 are symmetrically installed between the two distillation tower tubes 1. The two distillation tower tubes 1 are connected together by the two supporting arc plates 6. The supporting arc plates 6 can play a certain supporting role, and the height of the supporting arc plates 6 is greater than the height of the filler, so that the filler can be taken out from the spacing between the two distillation tower tubes 1. It should be noted that the width of the filler is less than the spacing between the two supporting arc plates 6. A fixed annular component 2 is fixedly installed on the surface of the distillation tower tube 1, and a fixed annular component 2 is fixedly installed on the surface of each distillation tower tube 1. The outer sides of the two supporting arc plates 6 Two semicircular closed shells 3 are sleeved, and multiple threaded rods 4 are installed in an array at the upper and lower ends of the closed shells 3. The multiple threaded rods 4 penetrate into the interior of the fixed annular component 2 through multiple adaptive through holes and are threadedly connected through nuts. The two semicircular closed shells 3 are combined into a complete ring and sleeved at the connection between the two distillation tower tubes 1 to play a sealing role. The threaded rods 4 at the upper and lower ends are connected to the fixed annular component 2. Since the positions of the two fixed annular components 2 and the two distillation tower tubes 1 are fixed, the position of the closed shells 3 threadedly connected to the fixed annular component 2 is fixed. When the packing needs to be replaced, it is only necessary to disconnect the threaded connection relationship between the threaded rods and the fixed annular component 2 to release the connection relationship between the closed shell 3 and the distillation tower tube 1, and then remove the two closed shells 3. The packing can be regularly replaced without disassembling the entire distillation tower.

[0022] Specifically, an annular sealing groove 5 is provided on the surface of the two distillation tower tubes 1, and two semicircular arc blocks 8 are installed in an array inside the two closed shells 3. The positions and sizes of the two arc blocks 8 are adapted to the two sealing grooves 5. By providing the sealing groove 5 on the surface of the distillation tower tube 1 and installing the arc blocks 8 inside the closed shell 3, when installing the closed shell 3, the arc blocks 8 are snapped into the inside of the closed groove, which can increase the connection strength between the closed shell 3 and the distillation tower tube 1 and enhance the sealing of the connection.

[0023] Furthermore, a mounting plate 7 is installed at both ends of the closed shell 3, and the two mounting plates 7 are threadedly connected by bolts 9, such as Figure 3 As shown, the two closed shells 3 are threadedly connected by bolts 9 to enhance the connection strength of the two closed shells 3 .

[0024] Furthermore, multiple grooves 10 are arranged in an array at the upper and lower ends of the closed shell 3, and a spring telescopic rod 11 is installed inside the groove 10. The other end of the spring telescopic rod 11 away from the groove 10 is connected to one end of the threaded rod 4. Under the action of the spring telescopic rod 11, the threaded rod 4 can be lifted and lowered within a certain range inside the groove 10. When the closed shell 3 needs to be installed, the multiple threaded rods 4 are first squeezed in the direction of the groove 10 to reduce the extension length of the threaded rod 4, and then the closed shell 3 is sleeved on the outside of the connection between the two distillation tower tubes 1, and the force squeezing the threaded rod 4 is removed. Under the action of the spring telescopic rod 11, the threaded rod 4 will be ejected and penetrate into the interior of the fixed annular assembly 2 through the through hole, and then fixed in position by a nut. The disassembly process is the same as the installation process. First remove the nut, then squeeze the threaded rod 4 into the interior of the groove 10, and then remove the closed shell 3.

[0025] Furthermore, the fixed annular assembly 2 includes a first fixed annular plate 201, a connecting rod 202 and a second fixed annular plate 203. The first fixed annular plate 201 and the second fixed annular plate 203 have the same size and are both fixedly mounted on the surface of the distillation tower tube 1. The first fixed annular plate 201 and the second fixed annular plate 203 are connected by a plurality of connecting rods 202. The first fixed annular plate 201 is used to connect the closed shell 3 of the upper distillation tower tube 1, and the second fixed annular plate 203 is used to connect the closed shell 3 of the lower distillation tower tube 1. The surfaces of the first fixed annular plate 201 and the second fixed annular plate 203 are both provided with a plurality of through holes. The connecting rods 202 installed between the first fixed annular plate 201 and the second fixed annular plate 203 can increase the connection strength. It should be noted that the through holes and the connecting rods 202 need to be staggered.

[0026] The method of using this embodiment is as follows: a filler is installed at the connection of two distillation tower tubes 1, the spacing between the two distillation tower tubes 1 is greater than the width of the filler, the two distillation tower tubes 1 are supported by a supporting arc plate 6, two semicircular closed shells 3 are combined into a complete ring and are sleeved at the connection between the two distillation tower tubes 1 to play a sealing role, and are connected to the fixed annular component 2 through the threaded rods 4 at the upper and lower ends. Since the positions of the two fixed annular components 2 and the two distillation tower tubes 1 are fixed, the position of the closed shell 3 threadedly connected to the fixed annular component 2 is fixed. When the filler needs to be replaced, it is only necessary to disconnect the threaded connection relationship between the threaded rod and the fixed annular component 2 to release the connection relationship between the closed shell 3 and the distillation tower tube 1, and then remove the two closed shells 3, so that the filler can be regularly replaced without disassembling the entire distillation tower.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
