Description

Technical Field

[0001] The utility model application relates to the technical field of mechanical processing, in particular to a single-layer coil structure of a reactor heat exchange tube. Background Art

[0002] The reactor heat exchange tube single-layer coil structure is a device used for heat transfer in a reactor. It is usually composed of one or more coils. These coils transfer heat from the inside of the reactor to the outside or from the outside to the inside of the reactor by heat conduction.

[0003] In the prior art, for example, Chinese patent announcement number: CN213956104U discloses "a single-layer coil structure of a reactor heat exchange tube", which includes a coil, a column, a U-shaped pipe clamp and a nut. The coil is a coaxial spring-type spiral tube structure, and three columns are radially evenly distributed on the outer circumference of the coil. A plurality of U-shaped pipe clamps are evenly installed at intervals above and below the column. The inner side of each U-shaped pipe clamp wraps around the adjacent coil, and the two tail ends of the U-shaped pipe clamp pass through the column and are locked with a nut.

[0004] However, in the prior art, the single-layer coil structure of the heat exchange tube is mostly fixed and installed inside the reactor by multiple fixing bolts or welding. During long-term use, scale will be deposited at the connection between the coil and the reactor and on the surface of the coil. Since the single-layer coil structure of the heat exchange tube is fixed as a whole inside the reactor, the internal space of the reactor is small, which makes it difficult to clean the connection between the coil and the reactor and the surface of the coil. The welding fixation method will make it impossible to disassemble and clean the coil. At the same time, the method of fixing it with multiple fixing bolts will make it difficult to disassemble and install the coil, which is inconvenient to clean and maintain the coil. Summary of the invention

[0005] In order to solve the problem that the single-layer coil structure of the heat exchange tube is mostly fixed and installed inside the reactor by multiple fixing bolts or welding, during long-term use, scale will be accumulated at the connection between the coil and the reactor and on the surface of the coil. Since the single-layer coil structure of the heat exchange tube is fixed inside the reactor as a whole, the internal space of the reactor is narrow, which makes it difficult to clean the connection between the coil and the reactor and the surface of the coil. The welding fixation method will make the coil unable to be disassembled and cleaned. At the same time, the method of fixing it with multiple fixing bolts will make it difficult to disassemble and install the coil, and it is inconvenient to clean and maintain the coil. The utility model provides a single-layer coil structure of heat exchange tubes for a reactor to solve the above problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A single-layer coil structure of a reactor heat exchange tube comprises a coil mechanism, a mounting mechanism is installed at the lower part of the coil mechanism, the coil mechanism comprises a coil body, and a bottom plate is fixedly connected to the lower part of the coil body;

[0008] The mounting mechanism includes a fixing plate, a support rod is fixedly connected to the center of the fixing plate, a limiting plate is fixedly connected to the top of the support rod, a No. 2 limiting groove is provided at the center of the bottom plate, the limiting plate is located inside the No. 2 limiting groove and is clamped with the bottom plate, and the support rod is plugged into the bottom plate.

[0009] Furthermore, a mounting plate is fixedly connected to a side surface of the bottom plate, a connecting plate is fixedly connected to a side surface of the mounting plate, a fixing block is fixedly connected to a side surface of the connecting plate, and the fixing block is fixedly connected to the coil body.

[0010] Furthermore, a limiting rod is fixedly connected to the upper portion of the fixed plate, a limiting groove No. 1 is arranged at the lower portion of the base plate, and the top end of the limiting rod is located inside the limiting groove No. 1 and is slidably connected to the base plate.

[0011] Furthermore, a spring is arranged on the surface of the limiting rod, one end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the supporting plate.

[0012] Furthermore, the support plate is slidably connected to the surface of the limiting rod.

[0013] Furthermore, a third limiting groove is provided on the side of the limiting rod, a limiting block is slidably connected inside the third limiting groove, the limiting block is fixedly connected to the support plate, and the support plate is fitted with the bottom of the base plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, the second limiting groove on the surface of the bottom plate is plugged into the limiting plate on the top of the support rod. When the limiting plate is plugged into place, the rotating support plate drives the mounting plate and the bottom plate to rotate, and the bottom plate is rotated ninety degrees so that the limiting plate and the bottom plate are clamped, which is convenient for limiting and fixing the bottom plate. When the coil body needs to be disassembled and cleaned, the bottom plate only needs to be rotated ninety degrees in the opposite direction to release the clamping connection between the limiting plate and the bottom plate, which is convenient for disassembling and cleaning the coil body.

[0016] 2. In the utility model, during the process of plugging the bottom plate and the limit plate, the No. 1 limit groove is plugged into the upper part of the limit rod, and at the same time, the bottom plate and the surface of the support plate are squeezed. At this time, the support plate slides along the surface of the limit rod, and the spring is compressed and deformed. When the bottom plate is installed in place, the bottom of the bottom plate is supported by the elastic force of the spring, thereby improving the stability of the bottom plate after installation.

[0025] The mounting mechanism 2 includes a fixing plate 21, a support rod 27 is fixedly connected to the center of the fixing plate 21, a limiting plate 28 is fixedly connected to the top of the support rod 27, a second limiting groove 29 is provided at the center of the bottom plate 22, the limiting plate 28 is located inside the second limiting groove 29 and is clamped with the bottom plate 22, and the support rod 27 is plugged into the bottom plate 22.

[0026] Specifically, the fixing plate 21 is welded and fixed to the bottom of the reactor. When the coil body 11 is installed, the bottom plate 22 is placed into the reactor by holding the connecting plate 13, and the limiting plate 28 on the top of the support rod 27 is plugged into the No. 2 limiting groove 29 on the surface of the bottom plate 22. When the limiting plate 28 is plugged into place, the rotating connecting plate 13 drives the mounting plate 14 and the bottom plate 22 to rotate, and the bottom plate 22 is rotated ninety degrees so that the limiting plate 28 and the bottom plate 22 are clamped, which is convenient for limiting and fixing the bottom plate 22. When the coil body 11 needs to be disassembled and cleaned, it is only necessary to rotate the bottom plate 22 in the opposite direction ninety degrees to release the clamping connection between the limiting plate 28 and the bottom plate 22, which is convenient for disassembling and cleaning the coil body 11.

At this time, the spring 24 is compressed and deformed. When the bottom plate 22 is installed in place, the bottom of the bottom plate 22 is supported by the elastic force of the spring 24;

[0032] When the support plate 25 slides along the surface of the limiting rod 23 , the support plate 25 drives the limiting block 211 to slide along the third limiting groove 210 to limit the movement of the support plate 25 .
