Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a shell and tube cooler. Background Technique

[0002] The shell and tube cooler is a common heat exchange device, mainly used for the cooling requirements in industrial systems. The shell and tube cooler uses a tube bundle for heat exchange. Among them, the liquid flowing inside the tube is the tube side, and the liquid flowing outside the tube is the shell side. The shell and tube cooler adopts a bare tube heat transfer tube, with a high film heat transfer coefficient outside the tube and strong anti-pollution ability. Its working principle and structural design enable it to be widely used in multiple industries, mainly for heat exchange in large refineries, chemical plants, thermal power plants, etc.

[0003] In the prior art, the shell and tube cooler mainly consists of a shell, tube sheets, partition plates, and cooling tube bundles, etc. Among them, the staff can optimize the fluid distribution between the tubes by adjusting the distance between the partition plates on the cooling tube bundle to make the heat exchange more uniform. However, since the shell and tube cooler will vibrate during use, after long-term vibration, the installation hole grooves on the cooling tube bundle and the partition plates will wear, resulting in the partition plates may shift, causing the partition plates to deviate from the pre-set position, and further affecting the turbulence degree of the fluid between the partition plates, resulting in the heat exchange efficiency of the cooler being affected.

[0006] Multiple partition plates, multiple uniformly distributed heat exchange tubes are arranged in the middle of the partition plates, multiple uniformly distributed notches are formed on the surfaces of the partition plates, a moving frame is slidably installed in each notch, an adjusting bolt is rotatably installed in the middle of one side of the notch close to the middle of the inside of the partition plate, the moving frames are respectively threadedly connected to the outer circumference of the adjusting bolts on the same side, and a limiting frame is symmetrically and fixedly installed on one side of the moving frame close to the heat exchange tube, and an arc groove corresponding to the heat exchange tube is arranged on one side of the limiting frame close to the heat exchange tube.

[0007] Preferably, a tube sheet is arranged on one side of the heat exchange tube, and a hole groove adapted to the heat exchange tube is formed on the surface of the tube sheet.

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present utility model, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 to 4 Figures 1 to 4 , the present utility model provides a technical solution: a shell and tube cooler, comprising: a plurality of partition plates 2, in the middle of each partition plate 2, a plurality of heat exchange tubes 3 are evenly distributed, on the surface of each partition plate 2, a plurality of evenly distributed notches 9 are provided, in each notch 9, a moving frame 7 is slidably installed, in the middle of one side of each notch 9 close to the middle part inside the partition plate 2, an adjusting bolt 8 is rotatably installed, the moving frames 7 are respectively threadedly connected to the outer periphery of the adjusting bolts 8 on the same side, on one side of each moving frame 7 close to the heat exchange tube 3, a limiting frame 6 is symmetrically and fixedly installed, and on one side of each limiting frame 6 close to the heat exchange tube 3, an arc groove corresponding to the heat exchange tube 3 is provided. When it is necessary to adjust the distance between the partition plates 2 installed on the heat exchange tubes 3, at this time, the staff uses an external auxiliary wrench to rotate the adjusting bolt 8 clockwise. Under the cooperation of the thread, the moving frame 7 will move along the notch 9 until the limiting frame 6 disengages from the surface of the heat exchange tube 3. Furthermore, the staff can move the partition plate 2. After the adjustment is completed, the staff rotates the adjusting bolt 8 counterclockwise. At this time, the moving frame 7 will drive the limiting frame 6 to approach the heat exchange tube 3, and then the partition plate 2 can be limited and fixed. By using the limiting frame 6 to fix the heat exchange tube 3, it is avoided that after the partition plate 2 is used for a long time, the holes and grooves on the partition plate 2 will be worn, resulting in deformation of the holes and grooves on the partition plate 2. Furthermore, the partition plate 2 cannot be stably installed at the predetermined position and shifts, so that the turbulence degree of the fluid between the partition plates 2 is affected, and the heat exchange efficiency of the cooler is reduced.

[0022] On one side of the heat exchange tube 3, there is a tube sheet 1, on the surface of the tube sheet 1, holes and grooves adapted to the heat exchange tubes 3 are provided. On the other side of the heat exchange tube 3, there is a U-shaped tube. On one side where the U-shaped tubes are close to each other, a plurality of evenly distributed cushion strips 4 are provided. By providing the cushion strips 4, at the same time, the cushion strips 4 are made of elastic materials, which can effectively fix the ends of adjacent heat exchange tubes 3 and prevent the vibration of the U-shaped tube part of the heat exchange tubes 3 from affecting the use effect of the cooler. Arc-shaped anti-slip pads are installed in the arc grooves. By providing the anti-slip pads, the heat exchange tubes 3 can be firmly limited on the partition plates 2, avoiding the shift of the partition plates 2 during the later use process and affecting the distance between adjacent partition plates 2. On the surface of each partition plate 2, a plurality of evenly distributed guiding grooves 12 are provided. On both sides of each limiting frame 6, guiding plates 11 are fixedly installed, and the guiding plates 11 are respectively slidably installed in the guiding grooves 12 on the same side. By providing the guiding grooves 12 and the guiding plates 11, the movement of the limiting frame 6 can be assisted, and the movement stability of the limiting frame 6 can be increased. On the surface of each partition plate 2, a plurality of evenly distributed mounting holes 5 are provided. In the mounting holes 5 on the same side, fixing bolts 10 are provided.

[0023] During actual use, the staff rotates the adjusting bolt 8. With the cooperation of the threads, the limiting frame 6 can move along the notch 9. At this time, the heat exchange tube 3 loses its limit with the partition plate 2, so that the staff can adjust the distance between adjacent partition plates 2. After the adjustment is completed, the staff rotates the adjusting bolt 8 again. At this time, with the cooperation of the limiting frame 6, the guide plate 11 and the guide groove 12, the arc groove on the limiting frame 6 can be engaged with the surface of the heat exchange tube 3, and then the partition plate 2 and the heat exchange plate can be limited, preventing the partition plate 2 from shifting, affecting the dead zone formed by the fluid inside the cooler, and reducing the heat exchange effect.

[0024] Although the above description of the illustrative specific embodiments of the present application is provided for those skilled in the art of the present technology to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of the present technology, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all applications and creations using the concept of the present application are within the scope of protection.
