Background
With the upsizing of chemical equipment, a number of large vertical reactors are emerging. Some of these devices are up to 30 meters in height. Due to the process requirements, these reactors have to be provided with internal tubes inserted from the top into the bottom of the reactor for the measurement of liquid level, temperature etc. Because of the need of overhauling and maintenance, the inner extension pipes need to be designed into a pluggable structure, and the operation is convenient. The traditional design method adopts whole root or splice welding, takes the inner extension pipe as a whole, and realizes the detachability through the connection of the flange cover. For the shorter inner extension tube, the disassembly and assembly are easy. However, if the inner extension pipe is as long as 20 meters or even 30 meters, the whole inner extension pipe is difficult to be inserted and pulled out due to limited space or inconvenient operation. Although the diameter of the inner extension pipes is small, the weight is light, the length of the connecting pipes is very long, and the equipment is very high, so that a large crane with the height of 50 meters can be needed for disassembling and assembling the connecting pipes with the weight of tens of kilograms. The difficulty and cost of disassembly and assembly are great. From a manufacturing perspective, the inner tube is not suitable for splice welding because the inner surface of the tube does not allow for any height or deformation of the weld due to the need to insert an instrument for measuring temperature or liquid level. The manufacturing and transportation costs of the whole tube are also enormous.

Detailed Description
Referring to fig. 1-7, an inner extension pipe assembly of a vertical reactor comprises a plurality of pipe units 1 and a plurality of screwed joints 2, wherein connecting rings 3 are coaxially arranged on two end faces of each pipe unit 1, the inner diameter of each connecting ring 3 is equal to the inner diameter of each pipe unit 1, the outer diameter of each connecting ring 3 is smaller than the outer diameter of each pipe unit 1, external threads are arranged on the outer circumferential surface of each connecting ring 3, the rotation directions of threads at two ends of each pipe unit 1 are opposite, internal threads are coaxially arranged at two ends of the inner circumferential surface of each screwed joint 2, the rotation directions of the internal threads at two ends of each screwed joint 2 are opposite, the internal threads on each screwed joint 2 are mutually matched with the external threads on each pipe unit 1, and the outer diameter of each screwed joint 2 is equal to the outer diameter of each pipe unit 1.
In this embodiment, in the process of splicing the pipe units 1 into the inner extension pipe, two ends of the pipe units 1 with opposite screw thread rotation directions are respectively inserted into two ends of the screw thread joint 2, and then the screw thread joint 2 is rotated, so that the two pipe units 1 are mutually adjacent to be connected into a whole, and thus the inner extension pipe can be spliced, because the outer diameter of the screw thread joint 2 is equal to the outer diameter of the pipe units 1, after the two adjacent pipe units 1 are spliced in place on the inner extension pipe, the outer surface of the inner extension pipe is smooth, and the inner extension pipe can be installed and disassembled in a segmented manner, so that the manufacturing cost is reduced, and the problem that the whole inner extension pipe is difficult to be inserted into the vertical reactor 9 due to the fact that the space is limited at present is solved by the fact that the inner extension pipe is not convenient to be spliced in place by the way of the segmentation splicing and the segmented disassembly is also realized by the segmented splicing and the segmented transportation process.
As a preferred way, the lengths of the internal threads at both ends of each of the screw joints 2 are equal so that the portions of the spliced two adjacent pipe units 1 on the inner extension pipe inserted into the screw joints 2 are identical, thereby making the stress of each pipe unit 1 uniform over the entire inner extension pipe.
As a preferable mode, as shown in fig. 2, an annular limiting protrusion 4 is arranged between two sections of internal threads in each threaded joint 2, the inner diameter of the limiting protrusion 4 is equal to the inner diameter of each pipe unit 1, and the length of each pipe unit 1 inserted into the threaded joint 2 is limited by the limiting protrusion 4, so that the length of an internal extension pipe spliced in the calculation is convenient.
As a preferred manner, as shown in fig. 3, an annular concave area 5 is coaxially arranged on the outer surface between the two ends of the threaded joint 2, the projection of the bottom surface of the annular concave area 5 on the end surface of the threaded joint 5 is a hexagon, and the geometric center of the hexagon is located on the axis of the threaded joint 2. So arranged, the threaded joint 2 is conveniently screwed down using the wrench 12.
As a preferred way, the cross section of the threaded joint 2 forms an outer circle which is the circumscribing circle of the hexagon. So arranged, the probability of the annular recess 5 being caught by the support 10 can be reduced during the extension of the inner extension pipe spliced from the pipe unit 1 into the vertical reactor 9. Because fillets coinciding with the outer circumferential surface of the nipple 2 and parallel to the axis of the nipple 2 are formed at the vertices of the hexagon.
As a preferable mode, six grooves 6 are formed in the outer circumferential surface of the threaded joint 2 in an equidistant circumferential array around the axis of the threaded joint 2, the grooves 6 are radially arranged on the threaded joint 2, the projection of the grooves 6 on any cross section of the threaded joint 2 is a combination of a rectangle and an arc, the straight edge of the arc is one edge of the rectangle, one end of the arc on the groove 6 faces the outside of the threaded joint 2, one end of the rectangle on the groove 6 faces the central axis of the threaded joint 2, a pressing block 7 is arranged in the groove 6 through a spring 8, the axis of the spring 8 is perpendicular to the axis of the threaded joint 2, the surface of the pressing block 7 facing the outside of the threaded joint 2 is a curved surface, the projection of the curved surface on any cross section of the threaded joint 2 is the same arc, and the radius of the virtual circle where the arc is located is equal to the radius of the outer circumferential surface of the threaded joint 2; in a state that the spring 8 is not elastically deformed, the virtual circle is an outer circle of the cross section of the threaded joint 2, and four side walls perpendicular to the bottom of the groove 6 on the pressing block 7 are in sliding contact with four inner side walls of the groove 6; in the contracted state of the spring 8, the pressing block 7 is completely entered into the rectangular portion of the recess 6. After such setting, in the process of splicing the pipe unit 1, the pressing block 7 can be squeezed into the rectangular part of the groove 6, so that the wrench 12 can clamp the threaded joint 2 conveniently (as shown in fig. 6 and 7), after the splicing is completed and the wrench 12 leaves the threaded joint 2, the pressing block 7 resumes to fill up the groove 6, so that the inner extension pipe can not be clamped by the hole edge of the through hole of the support 10 in the process of extending into the through hole of the support 10.
Preferably, the curved surface of the pressing block 7 is a rough surface, and the rough surface is provided to avoid slipping when the wrench 12 clamps the threaded joint 2.
