Description

Technical Field

[0001] The utility model belongs to the technical field of shell and tube heat exchangers and relates to a shell and tube heat exchanger supporting structure. Background Art

[0002] Shell and tube heat exchanger, also known as shell and tube heat exchanger, is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross section, easy to clean scale, and can be used under high temperature and high pressure. Among them, the steel shell and tube heat exchanger is a shell and tube heat exchanger with excellent performance. The shell and tube and other main components of the steel shell and tube heat exchanger are made of steel, which has high corrosion resistance and pressure bearing capacity. It is suitable for various complex environments and process conditions, and its structure is simple and compact, with high heat transfer efficiency. The internal heat transfer element is a steel pipe, and it is made of thin-walled steel pipe, which has high heat transfer efficiency and can achieve efficient heat exchange. At present, during use, the heat exchanger needs to be assembled with the support frame for use, and the shell and tube heat exchanger needs to be connected and fixed with the support frame. The existing utility model patent with patent number CN219454773U is a shell and tube heat exchanger with an auxiliary support structure, including a heat exchanger and a support frame arranged at the bottom of the heat exchanger, a mounting block is provided at the bottom of the heat exchanger, a positioning groove is provided on the mounting block, a fixed box is provided on the side wall of the support frame, an adjustment window is penetrated through the side wall of the fixed box, a positioning plate is provided inside, one end of the positioning plate passes through the fixed box and is arranged in the positioning groove, and the other end is connected to the fixed box through a reset device, and an adjustment device is provided on the top of the positioning plate, and the adjustment device cooperates with the adjustment window.

[0003] The prior art has the following technical defects:

[0004] When the above technical solution is installed and used, the supporting structure is too simple and does not have an adjustment function to adapt to heat exchangers of different sizes. The supporting effect becomes poor when facing heat exchangers of different sizes. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a shell and tube heat exchanger supporting structure.

[0006] The shell and tube heat exchanger support structure of the utility model comprises a heat exchanger and a base, wherein the base is provided with an adjusting structure, the adjusting structure is provided with a fixing structure, and a movable groove corresponding to the adjusting structure is provided on the top of the base.

[0007] Working process or working principle:

[0008] When in use, the heat exchanger is placed on the base, and the adjustment structure is adjusted so that the fixed structure can be driven to move through the movable groove, and the fixed structure is adjusted to contact the heat exchanger to achieve support and fixation of various specifications.

[0009] The adjustment structure includes a double-headed screw and a sliding rod arranged inside the base. The two ends of the double-headed screw are connected to moving arms corresponding to the moving grooves through main sleeves. Both moving arms are slidably connected to the sliding rod. The front end of the double-headed screw passes through the front surface of the base and is connected to an adjustment handle. By rotating the double-headed screw, the two ends of the screw with opposite threads can drive the moving arms to move toward or away from each other synchronously.

[0010] The two ends of the slide bar are respectively fixedly connected to the front and rear sides of the inner wall of the base, and the moving arm is slidably connected to the slide bar through the auxiliary sleeve. By setting the sleeve, the sliding stability of the moving arm on the slide bar is enhanced.

[0011] The movable arm is fixedly connected to the main sleeve and the auxiliary sleeve respectively, and the movable arm can move stably and synchronously on the double-headed screw and the sliding rod through the fixed arrangement.

[0012] The fixed structure includes a moving plate fixedly connected to the moving arm, a return spring fixedly connected to the moving plate, and a linkage plate fixedly connected to the other end of the return spring. The moving arm drives the moving plate to move so that the linkage plate contacts the heat exchanger for fixation.

[0013] The fixed structure includes a movable plate fixedly connected to the movable arm, a linkage arm is hinged on the top of the movable plate, a linkage groove is provided on the linkage arm, a movable rod is slidably connected in the linkage groove, both ends of the movable rod are fixedly connected with linkage rods, the linkage rod is slidably connected to the movable plate, the other end of the linkage rod is fixedly connected to the linkage plate, the top of the linkage arm is hinged with a fixed plate, and the movable plate is driven to move by the movable arm. As the linkage plate approaches the heat exchanger, the linkage plate is pushed by the heat exchanger and drives the movement of the linkage rod. The linkage rod drives the movement of the movable rod, and the movable rod drives the linkage arm through the linkage groove to rotate it on the top of the movable plate, thereby driving the fixed plate to approach the heat exchanger. As the heat exchanger continuously pushes the linkage plate, the fixed plate is close to the surface of the heat exchanger, thereby completing the support and fixation of the heat exchanger.

[0014] A return spring is arranged between the linkage plate and the movable plate. When fixation is not required, the return spring can make the fixed plate be at the highest position, which is convenient for fixation next time and will not hinder the placement of the heat exchanger.

[0015] The working surfaces of the linkage plate and the movable rod are both arc-shaped. The arc-shaped setting can increase the contact area between the fixed plate and the linkage plate and the heat exchanger, so that better fixation can be performed.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model can enable the adjusting structure to drive the fixed structure to move so as to be suitable for heat exchangers of different models and sizes, and the heat exchanger can be supported and fixed by driving the fixed structure to move through the heat exchanger.
