Description

Technical Field

[0001] The utility model relates to a heat exchange tube installation structure of a heat exchanger, belonging to the technical field of heat exchange equipment. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. According to the heat transfer principle, heat exchangers are classified into direct contact heat exchangers, compound heat exchangers, etc.; according to the structure, they are classified into floating head heat exchangers, fixed tube sheet heat exchangers, U-shaped tube sheet heat exchangers, plate heat exchangers, etc. [2] Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] Chinese patent number CN208805080U discloses a heat exchanger equipped with heat exchange tubes with bell-mouth sleeves. The heat exchanger comprises a heat exchanger shell, heat exchange tubes mounted in the heat exchanger shell via tube sheets at both ends, the heat exchange tubes comprising a heat exchange tube body, a plurality of bell-mouth sleeves mounted outside the heat exchange tube body, and a heat sink disposed between two adjacent bell-mouth sleeves. This application increases the heat exchange efficiency of the heat exchanger by simply changing the structure of the heat exchange tubes in the heat exchanger.

[0004] However, during the disassembly and assembly of the existing heat exchanger, when the heat exchange tubes are displaced in and out of the shell, multiple tubes need to be manually lifted together to allow them to extend smoothly into the shell, which is time-consuming and labor-intensive, and inefficient. The lack of an auxiliary installation structure is not conducive to ensuring the smoothness of the installation process.

[0005] To this end, a heat exchange tube installation structure of a heat exchanger is proposed. Utility Model Content

[0006] In view of this, the present invention provides a heat exchange tube installation structure of a heat exchanger to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the present utility model is implemented as follows: a heat exchange tube installation structure of a heat exchanger includes a heat exchanger shell, the inner end of the heat exchanger shell is fixedly connected to an internal interlayer, the inner side walls of the internal interlayer are provided with concave sliding grooves on all sides, circular pairs of plates are installed on the front and back sides of the inner end of the heat exchanger shell, a plurality of heat exchange tube bodies are fixedly connected to the inner end between the two circular pairs of plates, and the plurality of heat exchange tube bodies extend into the heat exchanger shell, the outer ends of the circular pairs of plates are fixedly connected to concave blocks on all sides, the two ends of the concave blocks are symmetrically fixedly connected to side vertical plates, and a roller slide is installed between the two corresponding side vertical plates.

[0008] Further preferably, the plurality of roller slides respectively penetrate into the corresponding concave slide grooves, and the plurality of roller slides are slidably connected to the corresponding concave slide grooves.

[0009] Further preferably, covers are provided at both the front and rear ends of the heat exchanger housing, and the covers are threadedly connected to the heat exchanger housing.

[0010] Further preferably, a sealing inner ring is fixedly connected to one end of the cover body close to the heat exchanger shell, and the sealing inner ring is in contact with the front and rear outer walls of the heat exchanger shell.

[0011] Further preferably, a pair of hollow columns are detachably connected to the ends of the two circular pairs of plates that are away from each other, and the two hollow columns are arranged in bilateral symmetry.

[0012] Further preferably, the upper inner wall of the hollow column is fixedly connected with a fixable stretch strip, and the fixable stretch strip passes through the outside of the hollow column.

[0013] Further preferably, the lower end of the fixable tensile strip is fixedly connected to a sealing outer column, and the sealing outer column contacts the ground.

[0014] Further preferably, the ends of the sealing outer column and the fixable tensile strip close to each other are fixedly connected with a bottom gasket, and the bottom gasket and the hollow column are engaged with each other.

[0015] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0016] 1. In this solution, when multiple heat exchange tubes follow the circular plates at both ends to enter and exit the heat exchanger shell, the four roller slides on the outside of the circular plates can be docked with the four concave slide bars on the inner wall of the internal interlayer, so that the circular plates can be smoothly aligned with the inside of the heat exchanger shell. At this time, the multiple heat exchange tubes are pushed into the heat exchanger shell along the circular plates. At the same time, the roller slides on the outside of the circular plates slide in the concave slide bars, and the multiple heat exchange tubes can be installed into the heat exchanger shell following the circular plates in a time-saving and labor-saving manner. The installation efficiency is high and the docking accuracy is high, which helps to reduce the amount of manual work.

[0017] 2. At the same time, when the multiple heat exchange tubes in the heat exchanger shell are pulled out of the heat exchanger shell for inspection and maintenance, the fixed tensile strip in the hollow column in front of the heat exchanger shell can be pulled down to make the sealing outer column under the fixed tensile strip contact with the ground, so that the outer position of the hollow column can be supported, and manual limiting is no longer required, which facilitates the maintenance of the hollow column. At the same time, when the fixed tensile strip is retracted, a sealing outer column can be set between the sealing outer column and the fixed tensile strip. The sealing outer column keeps the inside of the hollow column sealed, so that the liquid in the heat exchanger shell is not easy to extend into the hollow column, so that the use efficiency of the fixed tensile strip is guaranteed.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
